　<< 1. Introduction
　　>> <1.1. MEC>
　　(1) Overview
　First, referring to FIG. 1, an outline of the MEC.
[0016]
　Figure 1 is an explanatory diagram for explaining the outline of the MEC. In Figure 1, the upper, the current represented by LTE (Long Term Evolution) (MEC is not introduced) in a mobile communication, it shows the communication path for UE (User Equipment) to access the applications and content ing. Further, the lower, when the MEC is introduced shows a communication path for the UE to access the application and content.
[0017]
　As shown in the upper part of FIG. 1, in a mobile communication situation, the application and the content is arranged in the IP network is a EPC (Evolved Packet Core) than outside (farther from the UE). Thus, UE may or run the application, in order to or to acquire the content, the relay network in the middle of the route to the data center (e.g., Backbone network), EPC, backhaul link, a base station, and access It was communicating through all the links. Therefore, vast network cost and delay has occurred.
[0018]
　On the other hand, as shown in the lower part of FIG. 1, in the MEC, applications and content are held in EPC inner (closer to the UE side). For example, in the example shown in FIG. 1, the base station are integrally formed with MEC server (i.e., the edge server) functions as an application server and a content server. Thus, UE may or run the application, in order to or to acquire the content may be performed only communicate with inside the EPC. Therefore, by introducing the MEC, not only can communicate extremely low delay, other than the access link (e.g., backhaul link, EPC, and transit network) allows also reduction of traffic. Furthermore, the traffic reduction other than delay reduction and access link communications, increased throughput, and may also contribute to lower power consumption of the UE and the network side. Thus, the introduction of MEC, user, network provider, the service provider may born many benefits. MEC is more locally (i.e., closer to the UE) because distributed processing of data, in particular application to application rooted in the region is expected.
[0019]
　Incidentally, FIG. 1 shows an example in which MEC server is formed integrally with the base station, the present technology is not limited to the embodiment. MEC server may be formed as a device different from the base station may be base station and physical away. In the present embodiment, as an example, MEC server is described as being provided integrally with the base station. Hereinafter, a base station and integrally formed MEC server, also referred to as MEC server corresponding to the base station, as well the reverse, also referred to as a base station corresponding to the MEC server.
[0020]
　　(2) Platform
　Next, with reference to FIG. 2, illustrating the MEC server platform.
[0021]
　Figure 2 is an explanatory diagram for explaining the MEC server platform. 3GPP radio network element is a component of the lowermost layer (3GPP Radio Network Element) is a base station equipment such as antennas and the amplifier. Thereon, hosting infrastructure (Hosting Infrastructure) includes a hardware resource such as a server equipment (Hardware Resources), made from them virtualization layer formed by software virtualization (Virtualization Layer), common virtual it is possible to provide a server technology. On this virtual server, application platform (Application Platform) is operated.
[0022]
　Virtualization Manager (Virtualization Manager) manages such generation and extinction of VM each application of the top-level (MEC App) is vessel to operate (Virtual Machine). Since each application can be performed by different companies, the virtualization manager although considerations separation or the like of the resource security and allocating are determined, it is possible to apply the general cloud infrastructure technology.
[0023]
　Application Platform Services (Application Platform Service) is a collection of characteristic common services to MEC. Traffic offloading (Traffic Offload Function) is a the case of the process (the parent application on the data server) when the on the internet application a request from the UE to the application processing on the MEC server, switching control of such routing I do. Wireless Network Information Service (Radio Network Information Services), if the application on the MEC server requires radio status information strength such radio waves between the base station and the UE corresponding to the MEC server, the underlying wireless network to get the information from to provide to the application. Communication Services (Communication Services), each application on the MEC server provides a path when communicating with the application on the UE or the Internet. Service Registry (Service Registry), when there is generated or operation requirements of each application on the MEC server, or authenticate the application legitimate ones, registered, answer inquiries from other entities.
[0024]
　Or on the application platform described, each application running on each VM, provides various services to the UE by or in cooperation behalf of the application on the Internet.
[0025]
　MEC server, so be placed in a number of base stations is assumed, considering the mechanism to manage and coordinating multiple MEC between servers is also determined. Hosting Infrastructure Management System (Hosting Infrastructure Management System), an application platform management system (Application Platform Management System), an application management system (Application Management System) manages each corresponding entity on MEC server, linking.
[0026]
　　(3) of standardization trends
　in Europe, in October 2014, ISG (Industry Specification Groups) is installed to ETSI, standardization work of the MEC has been started. The first specification to the 2016 year-end target, has been promoted the current standardization work. More particularly, ETSI ISG NFV (Network Function Virtualization ) and cooperation of the original, such as 3GPP, standardization standardization in the center of the API for the MEC realization is underway.
[0027]
　　<1.2. Paging>
　　(1) LTE system configuration
　First, with reference to FIG. 3, the structure of the LTE core network.
[0028]
　Figure 3 is an explanatory diagram for explaining an example of the configuration of the LTE core network. 3 shows the configuration of the IP network to the base station.
[0029]
　MME (Mobility Management Entity) (typically, eNodeB) base station by S1-MME interface accommodates, mobility management of the terminal authentication (including security control), and the setting processing of the transfer path of the user data do. The MME, the mobility management and authentication of the terminal is performed in cooperation with HSS (Home Subscriber Server) by the S6a interface. With respect to mobility management, for efficient location management registration process by the movement between the radio area of ​​the LTE and 3G, MME via's S3 interface, the SGSN is a logical node 3G core network (Serving GPRS Support Node) it is possible to perform cooperative location registration control. Further, MME is between eNodeB and S-GW (Serving Gateway), the S1-MME and S11 interface to send and receive control signals, the user data in the S1-U interface is a section eNodeB from S-GW for setting and releasing the transfer path.
[0030]
　PCRF determines the policies such as QoS and charging methods for communicating quality control in P-GW, S-GW and Trusted Non-3GPP IP Access, distribute the policy information through the respective Gx, Gxc and Gxa interface to.
[0031]
　HSS is a subscriber information database of subscriber users the operator is contracted (e.g., UE). HSS manages information such as, for example, is present where the authentication information and current. Also, HSS controls the service provided to the UE. If the UE is as roaming, it is managed by the HSS being in roaming.
[0032]
　The S-GW, mainly dealing with data of user plane (IP data). S-GW is an entity that the RAN (Radio access network) relayed between the core network, while corresponding to each UE mobility, responsible for the routing of the data.
[0033]
　P-GW (Packet Data Network Gateway) is primarily handled data of user plane (IP data). P-GW is an entity relayed between the core network and the external network. Further, P-GW is a policy control of the core network and provides for RAN, charging control, also perform IP address management. S-GW and P-GW is logically a separate entity, sometimes physically identical.
[0034]
　SGSN (Serving GPRS Support Node) is an entity that has the function of both the MME and S-GW. The SGSN, type of network (GPRS (General Packet Radio Services)) and is the entity that exists on the type of RAN (WCDMA (TM) / GMS). The SGSN, because it has the function of both the MME and S-GW, so that the handle control plane, both user plane.
[0035]
　eNB each other, logically are connected by X2 interface is physically are connected via a core network, and can communicate with each other.
[0036]
　　(2) paging
　Subsequently, illustrating a paging in LTE.
[0037]
　In LTE, mainly the UE in idle mode because the network side call, a technique called paging is used. Paging, for example, incoming data or voice, used for emergency notification, etc., such as tsunami warning. The main application is as follows.
[0038]
　Initiate a mobile · terminating PS (Packet Switching) data connection
　　(initialization of the PS data communication by the mobile)
　· Initiate a mobile terminating SMS connection
　　(initialization of SMS communication by the mobile)
　· Initiate a mobile terminating CS fallback connection
　　(mobile body circuit switched initialization fallback communication)
　- trigger a UE-to re-the acquire system information
　　(trigger to reacquire system information UE)
　, a provide ETWS (Earthquake and Tsunami Warning system) for notification
　　provides (ETWS notification)
　- a CMAS provide (Commercial Mobile Alert Service) notification
　　(CMAS provide notification)
[0039]
　Referring to FIG. 4, an example of a process flow according to the paging. Figure 4 is a sequence diagram showing an example of a paging procedure flow. This sequence, UE, eNB, and the MME involved.
[0040]
　As shown in FIG. 4, via the eNB from first MME, a paging message to the UE (also referred to as paging signals) is notified (step S10, S11). Paging message from MME to eNB is also referred S1AP paging message. Paging message from the eNB to the UE, also referred RRC paging message. The MME, for a plurality of TA (Tracking Area), and transmits the S1AP paging message (step S10). Each eNB generates an RRC paging message based on S1AP paging message received, and transmits to the UE (step S11). Here, MME is at the timing of transmitting a paging message to the paging timer T3413 (step S12).
[0041]
　UE is, if you find a paging message of itself addressed, the process proceeds to the random access procedure (step S13). Then, UE transmits RRC connection request (RRC Connection Request) to eNB (step S14), RRC connection setup (RRC Connection Setup) is performed by eNB (step S15).
[0042]
　The UE transits to the RRC connected state RRC connection setup is completed, it sends a service request to the eNB (step S16). Then, eNB sends a service request to the MME. MME receives the service request, stops the paging timer T3413 (step S18). Incidentally, when it is not possible to stop until the expiration of the Paging Timer T3413, the paging failure.
[0043]
　The UE, in order to implement paging correctly, it is necessary to read the paging signal received from the network side properly. However, if constantly awaits a signal from the network side, the power consumption of the UE becomes enormous. Therefore, in the LTE, DRX method (Discontinuous Reception) intermittent reception that it is incorporated. DRX is a mechanism that performs intermittent reception at a fixed cycle. The default value of the interval, SIB2 (System Information Block Type 2 ) is notified by a value set in the following range.
　　{32, 64, 128, 256 } [Radio Frames]
[0044]
　The value of the interval, it is possible to request from the UE side to the network side. In this case, possible values are the same, "Attach Request" or using "Tracking Area Update Request" is notified to the network side.
Incidentally, if the value of the default value and the UE requests are both set, a smaller value is employed of them.
[0045]
　UE based on the predetermined paging interval, and identification information of itself UE_ID information such as a frame for receiving paging signals: Set (PF Paging Frame). PF is calculated for example by the following equation.
[0046]
　　ＳＦＮ　ｍｏｄ　Ｔ＝（Ｔ／Ｎ）×（ＵＥ＿ＩＤ　ｍｏｄ　Ｎ）
　　Ｔ＝ＤＲＸ　ｃｙｃｌｅ　ｌｅｎｇｔｈ　ｒａｄｉｏ　ｆｒａｍｅｓ
　　Ｎ＝Ｍｉｎ（Ｔ，ｎＢ）
　　　　　　　　　　｛Ｔ，Ｔ／２，Ｔ／４，Ｔ／８，Ｔ／１６，Ｔ３２｝
　　ｎＢ：ｂｒｏａｄｃａｓｔ　ｉｎ　ＳＩＢ２
　　　　　　　　　　｛４Ｔ，２Ｔ，Ｔ，Ｔ／２，Ｔ／４，Ｔ／８，Ｔ／１６，Ｔ３２｝
　　ＵＥ＿ＩＤ＝ＩＭＳＩ　ｍｏｄ　１０２４
[0047]
　Then, UE is a subframe for receiving a paging signal in the PF (PO: Paging Occasion) determining. First, UE, due the following equations to calculate the parameters Ns, the I_s. Then, UE refers to Table 1 and Table 2 of the look-up table below (Look up table), to determine the PO.
[0048]
　　Ｎｓ＝Ｍａｘ（１，ｎＢ／Ｔ）
　　ｉ＿ｓ＝Ｆｌｏｏｒ（ＵＥ＿ＩＤ／Ｎ）ｍｏｄ　Ｎｓ
[0049]
[Table 1]

[0050]
[Table 2]

[0051]
　Parameter Ns is set to a cell-specific (Cell specific). The more the value of Ns is becomes larger, paging capacity (Paging capacity) increases.
[0052]
　The Subframe0,5, because it is in the synchronization signal or system information, it is impossible to set the MBSFN subframe. Therefore, if the paging information is also stored in the Subframe, specs impact is small. However, for the paging capacity of small (narrow bandwidth) cells, Subfmrae0,5 already no resources, it is difficult to store the paging information. Therefore, the cell paging capacity is small, except Subframe0,5, especially if the paging information tends to assign (4,9 to Subframe4,9, is that the UE read the sync signal and the system information immediately after the paging can, efficient). On the other hand, (a large paging capacity) relatively there is sufficient Subframe 0, 5 relative to the cell can be assigned a paging information to Subframe0,5.
[0053]
　In TDD case, it is necessary to map the paging information to at least DL (Downlink) subframe, always assigned to 0, 5 subframe with the Configuration of DL is the highest priority. In this case, it is acceptable crash paging and system information. For paging capacity is large cells, it is possible to use additionally Subframe1,6. Subframe1 is a Special subframe, Subframe6 is a Special subframe or DL ​​subframe. Special subframe, since the area of ​​the PDCCH is limited, can not be used in the cell paging capacity is small. Therefore, the paging information is assigned only to the paging capacity is high cell.
[0054]
　　<1.3. Technical Issues>
　paging in the current 3GPP manages a cohesive base stations that have MME as one TA. If the UE mobility is somewhat, such mobility management in large TA units are also considered to be effective. However, MME, to the target UE, and transmits the paging message in TA units, overhead is large according to the paging.
[0055]
　Here, when the MEC is introduced, from the MEC server provided in a location closer to the UE to UE, the service with low delay is provided. Nevertheless, for example, other UE call request from the UE, once it means reaching layers of MME, the latency is increased.
[0056]
　Therefore, it led to the creation of the system according to an embodiment of the present disclosure by one Viewpoints of the above circumstances. In the system according to this embodiment, by applying the concept of MEC to mobility management, the functions of the MME and HSS, arranged distributed at a position closer to the user. Accordingly relates mobility management, small communication overhead and latency is achieved.
[0057]

[0087]
　<< 4. Technical features >>
　Subsequently, explaining the technical features of the system 1 according to this embodiment.
[0088]
　(1) management information
　management device 300 (e.g., management unit 331) manages information of one or more terminal devices 200 located in the management area. Here management and includes storage of information, and to update the stored information. The information managed by the management device 300, also referred to as management information.
[0089]
　Terminal device 200 is managed by one or more management devices 300, including its location in the control area. Management device 300 may avoid duplication managed with other management device 300. For example, the management device 300 (e.g., manager 331), among the terminal apparatus 200 located within the management area of ​​itself may be managed terminal apparatus 200 is not more managed underlying other management device 300. Note that the the managed terminal device 200, is intended to refer to manage the management information of the terminal apparatus 200. That is, the management device 300 stores / updates the management information of the managed terminal apparatus 200. Furthermore, to the managed terminal device 200, it may refer to as a transmission origin of the paging message.
[0090]
　Management device 300 (e.g., manager 331) may acquire the management information from the MME or HSS. The management apparatus 300 may acquire the management information from other management device 300. The terminal device 200 (e.g., reporting section 241) is to the management device 300 itself managed, it may report management information thereof.
[0091]
　(2) Contents of the management information
　management information includes mobility information of the terminal apparatus 200, information about the application the terminal device 200 is used, or at least one of the attribute information of the terminal apparatus 200. Thus, the terminal device 200 can enter under the management of the management device 300 of the suits hierarchy own characteristics.
[0092]
　Mobility information may include location information of the terminal apparatus 200, the speed or direction of movement either at least. Thus, by predicting the management device 300 that manages the management area of ​​the movement destination, it is possible to ahead by notifying the like.
[0093]
　Attribute information, whether the terminal device 200 is a MTC device, whether a smart phone, such as may include a terminal category. Thus, the high and low mobility is predictable, the terminal device 200 can enter under the control of the management apparatus 300 suitable hierarchy.
[0094]
　(3) sharing
　the coordinator 400 assists the roles of the plurality of management devices 300.
[0095]
　For example, coordinator 400 (e.g., selector 433), based on the management information, it may be selected managed terminal apparatus 200 of each of the management apparatus 300. For example, coordinator 400 may be selected based on the attribute information of the terminal apparatus 200. More specifically, the coordinator 400, the terminal device 200 of low mobility as MTC devices as management targets of the underlying management device 300, the upper layer of the management apparatus 300 with high terminal device 200 of the mobility as automotive devices and managed. Additional coordinator 400 may be selected based on the application of the terminal device 200 is used. For example, if the application is communicating with the local area, such as battle game is performed is used, the coordinator 400, and managed underlying management device 300. Similarly, the coordinator 400 may be selected based on the mobility information of the terminal apparatus 200. Thus, the coordinator 400, the compatible management device 300 to the characteristics of the terminal device 200, it is possible to assign the management of the terminal device 200.
[0096]
　For example, coordinator 400 (e.g., storage control unit 431) is a hierarchical structure, and may also store information indicating the managed terminal device 200 of each of the management apparatus 300 (i.e., in the storage unit 420). More easily, the coordinator 400, which the management apparatus 300 of which layer is managing which terminal device 200, to grasp the. The information indicating the hierarchical structure information indicating the relationship between the management device 300. The information indicating the managed terminal device 200 of each of the management apparatus 300 is information indicating the relationship between the management device 300 and the terminal device 200. Based on this information, the coordinator 400, it is possible to perform accurately send and receive messages in the system 1. In the following, the information coordinator 400 stores, also called tree information.
[0097]
　Coordinator 400 (e.g., storage control unit 431) updates the tree information. For example, coordinator 400, according to the movement of the terminal device 200 may update the tree information. Accordingly, the coordinator 400 can correctly grasp the managed management device 300. Further, the coordinator 400 may update the tree information in response to changes in the hierarchy. Accordingly, the coordinator 400 can correctly grasp the hierarchical structure.
[0098]
　(4) Mobility Management
　management device 300 performs various processing for the mobility management.
[0099]
　For example, the management device 300 (e.g., manager 331) performs an attach procedure. For example, the management device 300 receives an attach request signal from the terminal apparatus 200 located in the control area, itself held, or on the basis of the acquired authentication information from the HSS, performs user authentication and bearer setup.
[0100]
　For example, the management device 300 (e.g., management unit 331) performs the paging procedure. For example, the management device 300 transmits a paging message to the managed terminal apparatus 200, receives a service request. Incidentally, the paging by the management apparatus 300 according to this embodiment, it may also referred to as a local paging.
[0101]
　In LTE, as a threshold value for determining a paging success / failure, it has paging timer T3413 is used in the MME. In contrast, in the present embodiment, instead of the timer of the paging timer T3413 (hereinafter, also referred to as local paging timer) is used. Management device 300 (e.g., manager 331), when the elapsed time from the transmission of the paging message exceeds local paging timer recognizes the movement possibilities of the management area outside the managed terminal apparatus 200. Note that the movability means there that may have been moving or moved.
[0102]
　Additional management device 300 (e.g., manager 331) may recognize the movability of the terminal device 200 based on information of the terminal apparatus 200. For example, the management device 300 determines the mobility information, the attribute of the terminal device 200, based on the use application or the like, the terminal device 200 is moved to the management area outside the own (i.e., deviating) possibilities. Thus, the management apparatus 300 before the terminal unit 200 moves actually outside the management area, it is possible to recognize the movement possibilities.
[0103]
　Management device 300 (e.g., the notification unit 333), when the movability of the management area outside the managed terminal apparatus 200 is recognized, the hierarchy of the terminal device 200 to the other management device 300 of the upper layer of the same or It notifies information indicating the movement possibilities. Thus, the periphery of the management apparatus 300, the movement possibilities are known. The notification destination may be controlled by the coordinator 400. For example, the management apparatus 300 inquires whether to notify to any other management device 300 to the coordinator, may notify based on the query result. Additional notification may be relayed by the coordinator 400.
[0104]
　Management device 300 (e.g., manager 331), if the information from the other management device 300 showing the movement possibilities of the terminal device 200 is notified, may send a paging message to the terminal device 200. For example, the management apparatus 300, based on a notification from the lower layer of the other management device 300 performs a paging procedure to target a wide management area than the lower layer. Thus, system 1, first in the minimum range, then with an increasing stepwise scope thereof, can make the search for the terminal device 200. In particular, with respect to the lower terminal device 200 of the mobility, it is possible to early detection. Note that when expanding the stepwise range (failed search) once search the management device 300 may be excluded from the search target. When a plurality of management apparatus 300 performs paging, it is desirable that each of the timing is shifted so as not to collide.
[0105]
　Incidentally, the local timer may be different for each hierarchy. The local timer is preferably shorter than the paging timer T3413. There is a possibility to be performed multiple times. Moreover, the sum of the local paging timer from the bottom layer to the top layer, it is desirable that less that or match the paging timer T3413. It raised one by one hierarchy, while expanding the range, because the paging may be performed.
[0106]
　Management device 300 (e.g., the notification unit 333) is to other management device 300 that manages the destination management area of ​​the terminal device 200, and notifies the management information of the terminal device 200. As a result, the management information is taken over from the source to the destination. The notification destination may be controlled by the coordinator 400. For example, the management apparatus 300 inquires whether to notify to any other management device 300 to the coordinator, may notify based on the query result. Additional notification may be relayed by the coordinator 400. Further, the destination management unit 300, the fact that managed the terminal device 200 that has potentially be newly moved or moving new and notifies the coordinator 400. Thus, the coordinator 400 is able to grasp the change in the managed management device 300.
[0107]
　Management device 300 (e.g., manager 331), when moved to the management area outside the managed terminal apparatus 200 is recognized (i.e., if the paging by another management device 300 is successful), the moved terminal 200 may exclude from the managed. As a result, the duplication of management target is eliminated. Further, the move source, the management information may be erased. However, basically, it is desirable that the management information is retained in each layer, it will not be erased (i.e., the management information is copied) it is desirable. That is, not an administrator managing apparatus 300 may also hold the management information. Incidentally, depending on the number of copying times or the update date and time, etc., it may be set the reliability of the management information. Further, the source management apparatus 300, the fact that excludes terminal device 200 that has moved from the managed, and notifies the coordinator 400. Thus, the coordinator 400 is able to grasp the change in the managed management device 300.
[0108]
　Here, in the above, along with the movement of the terminal apparatus 200, although the management apparatus 300 that manages an example has been shown to change from a lower layer to an upper layer, the reverse is also conceivable. For example, with the decrease or the like of the mobility, the management of the terminal apparatus 200 may be changed from the top of the management apparatus 300 to the underlying management device 300.
[0109]
　Management device 300 (e.g., manager 331), in the practice of the TA (Tracking Area) update, updates the management information of the managed terminal apparatus 200. That is, a plurality of management devices 300, and updates the management information collectively. Specifically, the management apparatus 300, based on the TA update message, recognizes the mobile terminal device 200, the above-described, the takeover of the management information from the source to the destination, and the management of the target deduplication etc. I do.
[0110]
　It has been described technical features of the system 1 according to this embodiment.
[0111]
　<< 5. Process flow >>
　Subsequently, an example of the flow of processing executed in the system 1 according to this embodiment. First, explaining the flow of basic processing, followed by explaining the flow of processing in a specific use case.
[0112]
　　<5.1. The basic processing flow>
　First, with reference to FIG. 10, to support paging by the management apparatus 300, an example of the flow of the processing performed in the coordinator 400.
[0113]
　Figure 10 is a flowchart showing an exemplary flow of a paging support processing that is executed in a coordinator 400 of the present embodiment.
[0114]
　As shown in FIG. 10, first, the coordinator 400 (e.g., selector 433) recognizes the movability of the terminal device 200 (step S102). For example, coordinator 400, from the management apparatus 300, when receiving a lost notification indicating that the local paging timer expires, recognizing the movement possibilities of the terminal apparatus 200.
[0115]
　Then, coordinator 400 (e.g., selector 433) may determine the initial search layer (step S104), and instructs the paging conducted management device 300 of the layer (step S106).
[0116]
　If the terminal device 200 is not found (step S108 / NO), the coordinator 400 (e.g., selector 433) is a search layer by one up (step S110), and instructs the paging performed again (step S106). Coordinator 400, these processes is repeated until the terminal is found, the process ends if it is found (step S108 / YES).
[0117]
　It has been described an example of the flow of the paging support processing. Subsequently, referring to FIG. 11, an example of the flow of local paging processing performed in the system 1.
[0118]
　Figure 11 is a sequence diagram showing an example of the flow of local paging processing performed in the system 1 according to this embodiment. As shown in FIG. 11, in this sequence, the terminal apparatus 200, the management device 300A of the layer A, the management device 300B of the layer B, and the coordinator 400 is involved. Layer A is assumed to be lower than the layer B.
[0119]
　First, management device 300A transmits a paging message to the terminal device 200 (step S202). Then, the management device 300A checks the lost terminal apparatus 200 based on the expiration of local paging timer (step S204), and transmits the lost notifications to the coordinator 400 (step S206). Note that the Lost notification, the lost management information of the terminal device 200 (at least, terminal ID) may be included.
[0120]
　Coordinator 400 reselects the management apparatus 300 (step S208). For example, coordinator 400 selects the upper layer of the management apparatus 300B than management device 300A. Then, the coordinator 400 sends a paging exemplary instruction to the management apparatus 300B (step S210).
[0121]
　Management apparatus 300B that has received the paging implementation instruction, transmits a paging message to the terminal device 200 (step S212). Terminal device 200 makes a response to successful reception of the paging message (step S214).
[0122]
　Management apparatus 300B that has received the response transmits a discovery-notification to the management device 300A via the coordinator 400 (step S216). Management apparatus 300A, in accordance with the discovery-notification, transmits the management information of the terminal apparatus 200 to the management device 300B via the coordinator 400 (step S218). The management device 300B registers the management information received (step S220).
[0123]
　It has been described an example of the flow of local paging.
[0124]
　　<5.2. Detailed Process Flow>
　Next, with reference to FIGS. 12 to 16, illustrating a detailed process flow.
[0125]
　　(1) call in application-based
　First, with reference to FIGS. 12 and 13, the terminal device 200, the application base, described use cases to invoke the neighborhood of the terminal device 200. This use case is, for example, terminal device 200A and 200B which are in close is the case corresponds to execute the game application involving communication. What game application without mobility (e.g., a game or the like performed by using the local information), then moving range is assumed to be somewhat limited. In such a use case, the management area is limited, the introduction of the management apparatus 300 according to this embodiment is effective.
[0126]
　In the following, first, with reference to FIG. 12, the flow of processing at the time of attaching.
[0127]
　Figure 12 is a sequence diagram showing an example of the flow of attach process performed in the system 1 according to this embodiment. As shown in FIG. 12, in this sequence, the terminal device 200A, 200B, management device 300A, 300B, and the coordinator 400 is involved. Management device 300B is assumed to be the uppermost layer of the MME / HSS.
[0128]
　First, the terminal device 200A and 200B sends an attach request to the MME / HSS300B (step S302). With or separately this attach request, information about the application to be used is transmitted to the MME / HSS300B.
[0129]
　MME / HSS300B transmits the management information of the terminal device 200A and 200B to the coordinator 400 (step S304).
[0130]
　Coordinator 400 checks the management information received (step S306), and selects the management device 300 that manages the attach request source terminal device 200A and 200B (step S308). For example, the coordinator 400 is included in the management information, it determines on the basis of information about the application that uses the terminal device 200A and 200B is managed by MME / HSS300, or management by the lower layer of the management apparatus 300 one is appropriate. For example, the application determines that as long as such work only in a particular area, the coordinator 400 should be managed by the lower layer of the management apparatus 300. Here, it is assumed that the management device 300A is determined that it should be managed.
[0131]
　In that case, the coordinator 400 sends an administrator change request indicating that change the administrator terminal device 200A and 200B to the management apparatus 300A to the MME / HSS (step S310).
[0132]
　Then, coordinator 400 transmits the activation message to the management device 300A (step S312). Management device 300A is activated based on the activation message (step S314). Incidentally, if you are already already activated the management device 300A, these processes may be omitted.
[0133]
　Next, the management apparatus 300A receives the control information of the terminal device 200A and 200B from the MME / HSS300B (step S316).
[0134]
　The management device 300A performs an attach accept processing of bearer setup or the like (step S318), and transmits the attach completion notification to the terminal apparatus 200A and 200B (step S320). Thus, attachment management is initiated by the management device 300A.
[0135]
　It has been described an example of the flow of attach procedure.
[0136]
　In the above sequence, in steps S302 and 304, information about the applications terminal 200 is used by, an example has been described that is provided from the terminal apparatus 200, the present technique is not limited to such an example. For example, application information, the application layer (e.g., an application server 60 or MEC server) may be provided from.
[0137]
　Subsequently, referring to FIG. 13, an example of the flow of processing when the local paging. More specifically, the terminal device 200B is the local paging process will be described in the case to call the terminal device 200A that transition to IDLE mode. Besides the case that call, the same processing at the paging procedure in the update or the like of the system information may be performed. In FIG 13 shows an example of a case where the paging by the management device 300A has succeeded. Example when paging by the management apparatus 300A fails will be described in detail later with reference to FIG. 14.
[0138]
　Figure 13 is a sequence diagram showing an example of the flow of local paging processing performed in the system 1 according to this embodiment. As shown in FIG. 13, in this sequence, the terminal device 200A, 200B, and the management apparatus 300A of the layer A is involved. Layer A is assumed to be lower than the layer B.
[0139]
　As shown in FIG. 13, the terminal device 200A is IDLE state (step S402), the terminal apparatus 200B is assumed to be CONNECTED state (step S404). First, the terminal device 200B performs a call of the terminal device 200A to the management apparatus 300A (step S406).
[0140]
　Then, the management apparatus 300A sets the local paging timer (step S408), and transmits a paging message to the terminal device 200A (step S410).
[0141]
　Terminal 200A receives the paging message (step S412), and transmits an RRC connection request (RRC Connection Request) to the management device 300A (step S414). The management device 300A transmits RRC connection setup complete (RRC Connection Setup complete) to the terminal device 200A (step S416).
[0142]
　Thus, the process ends.
[0143]
　　(2) search for with an increasing search range
　followed, with reference to FIGS. 14 and 15, it will be described use cases search terminal apparatus 200 while enlarging a search area. Incidentally, FIG. 14 shows an example of a time and searched (failed search) management device 300 is excluded from the search object, a search is performed in the new search range. Figure 15 is an example of a time and searched (failed search) management apparatus 300 without being excluded from the search target, the new search range is added. Further, FIG. 14 is an example in which search is performed by raising the hierarchy, Figure 15 is an example in which the search is performed in the same layer. Optionally such movement direction and the like are known a rough position is known, it is desirable to search the same hierarchy the position as management area is carried out. In either figure, in cases where reference to the above description of FIG. 13, an example of a case where the paging by the management apparatus 300A fails.
[0144]
　Figure 14 is a sequence diagram showing an example of the flow of local paging processing performed in the system 1 according to this embodiment. As shown in FIG. 14, in this sequence, the terminal device 200A, 200B, management device 300A of the layer A, the management of the layer B device 300B, MME / HSS300C, and the coordinator 400 is involved. Layer A is assumed to be lower than the layer B.
[0145]
　As shown in FIG. 14, the process in the step S502 ~ S510 are the same as the process in the step S402 ~ S410 described above with reference to FIG.
[0146]
　When the local paging timer expires (step S512), the management device 300A transmits the lost notifications to the coordinator 400 (step S514).
[0147]
　Then, coordinator 400 reselects the management apparatus 300 (step S516). For example, coordinator 400 selects the upper layer of the management apparatus 300B than management device 300A.
[0148]
　In that case, the coordinator 400 sends an administrator change request indicating that change the administrator terminal device 200A to the management apparatus 300B to the management apparatus 300A (step S518). Then, coordinator 400 transmits the activation message to the management device 300B (step S520). Management device 300B is activated based on the activation message (step S522). On the other hand, the management device 300A is to deactivate based on the administrator change request (step S524), and transmits the management information of the terminal device 200A to the management device 300B (step S526). Thus, the administrator of the terminal device 200A is changed to the management apparatus 300B.
[0149]
　As an alternative processing of steps S518 ~ according to S526 process (Alt.1) (Alt.2), management information may be transmitted from the MME / HSS300C to the management device 300B (step S528).
[0150]
　Then, the local paging is performed between the management device 300B and the terminal device 200A (step S530). Incidentally, if the local paging by the management device 300B also fails, the coordinator 400 may further perform the local paging by the upper or surrounding management device 300. Such repetition of the local paging is carried out until to the terminal device 200 is found, or to reach the MME / HSS of the highest level.
[0151]
　Thus, the process ends.
[0152]
　Figure 15 is a sequence diagram showing an example of the flow of local paging processing performed in the system 1 according to this embodiment. As shown in FIG. 15, in this sequence, the terminal device 200A, 200B, management device 300A of the layer A, the management of the layer A device 300B, MME / HSS300C, and the coordinator 400 is involved.
[0153]
　As shown in FIG. 15, in this sequence, the process in the step S502 ~ S510 described above with reference to FIG. 13, are omitted. As shown in FIG. 15, when the local paging timer expires (step S602), the management device 300A transmits the lost notifications to the coordinator 400 (step S604).
[0154]
　Then, coordinator 400 reselects the management apparatus 300 (step S606). For example, the coordinator 400 comprises a rough position of the terminal device 200A in the management area, selects the management device 300B of the management device 300A in the same hierarchy.
[0155]
　In that case, the coordinator 400 sends an administrator additional request indicates that adding a management device 300B to the administrator terminal device 200A to the management apparatus 300A (step S608). Then, coordinator 400 transmits the activation message to the management device 300B (step S610). Management device 300B is activated based on the activation message (step S612). On the other hand, the management device 300A, based on the administrator add request, it sends the management information of the terminal device 200A to the management device 300B (step S614). Thus, the management device 300B is added to the administrator of the terminal device 200A.
[0156]
　As an alternative processing of steps S608 ~ according to S614 process (Alt.1) (Alt.2), management information may be transmitted from the MME / HSS300C to the management device 300B (step S616).
[0157]
　Then, the local paging is performed between the management device 300A and the terminal device 200A (step S618), further, the local paging is performed between the management device 300B and the terminal device 200A (step S620).
[0158]
　Thus, the process ends.
[0159]
　　(3) Changing the administrator in accordance with the characteristics of the terminal device
　subsequently, with reference to FIG. 16, described use case of changing the administrator according to the characteristics of the terminal device 200. For example, the terminal device 200 moving speed is high, it is desirable to be managed in the management apparatus 300, i.e. the upper layer of the management apparatus 300 of the wide management area. Conversely, the terminal device 200 moving speed is low, it is desirable to be managed in the management apparatus 300, i.e. the lower of the management apparatus 300 of the narrow management area. Thus, the coordinator 400, according to the characteristics of the terminal device 200, assigns appropriate management apparatus 300 to the terminal device 200. In the following, the administrator of the moving speed is fast terminal apparatus 200, an example of the shift from the lower layer of the management apparatus 300 to the upper layer of the management apparatus 300.
[0160]
　Figure 16 is a sequence diagram showing an example of the flow of the administrator of the changing process executed in the system 1 according to this embodiment. As shown in FIG. 16, in this sequence, the terminal apparatus 200, the management device 300A of the layer A, the management device 300B of the layer B, MME / HSS300C, and the coordinator 400 is involved. Layer A is assumed to be lower than the layer B.
[0161]
　As shown in FIG. 16, first, the terminal device 200 transmits its mobility information to the management apparatus 300A (step S702). For example, the terminal device 200, the speed by using various sensors, and acquires information indicating the moving direction and geographical location, reports the information to the management device 300A.
[0162]
　Management apparatus 300A monitors the mobility information received from the terminal apparatus 200 (step S704), if the mobility information satisfies a predetermined condition, transmits the mobility information of the terminal device 200 to the coordinator 400 (step S706) . The predetermined condition, for example, such that the moving speed exceeds a predetermined threshold value are considered. If the moving speed is high, because the possibility that the terminal apparatus 200 to the management area outside of the underlying management device 300A is moved is increased.
[0163]
　Then, coordinator 400 reselects the management apparatus 300 (step S 708). For example, coordinator 400 selects the upper layer of the management apparatus 300B than management device 300A.
[0164]
　Subsequent steps S710 ~ S718 (Alt.1), and the process in the step S710 ~ S720 (Alt.2), the above described with reference to FIG. 14, steps S518 ~ S526 (Alt.1), and step S518 it is similar to the process according to ~ S528 (Alt.2). Thus, the administrator of the terminal device 200A is changed to the management apparatus 300B.
[0165]
　Thus, the process ends.
[0166]
