[0027]
　In the broadcasting system, emergency bulletin message (CBS message) is delivered from the CBE10 to UE14.
[0028]
　CBE10 is a installed in the information processing apparatus to the Japan Meteorological Agency and local governments (server), a distribution apparatus of emergency bulletins.
[0029]
　CBC11 is connected to the CBE10, a radio network controller installed in each communication service provider.
[0030]
　HNB-GW 12 is a gateway apparatus that relays data transmitted to and received from the HNB13 core network. That, HNB-GW (Home Node B-Gateway) 12 is a relay device in the femto system, a plurality of femto base stations; acts as a gateway that is connected to the (HNB Home Node B) directly.
[0031]
　Each HNB13-1 ~ 13-3, to provide wireless connectivity to UE (terminal) 14, to form a single cell. HNB13-1 ~ 13-3 are each a very narrow range covering a femto cell base station (small radio base station). Distance radio waves, each of which emits of HNB13-1 ~ 13-3 becomes the cell. For example, a HNB13-1 cell 201, HNB13-2 cell 202, HNB13-3 the cell 203, respectively. In the following description, if there is no special reason to distinguish HNB13-1 ~ 13-3 are simply referred to as "HNB13".
[0032]
　UE14 is a wireless terminal, the UE residing in each cell of HNB13, can be connected to HNB13. If there are multiple UE14 to each cell, each UE14 can be connected with HNB13.
[0033]
　One or more cells that considers one virtually has, service area; corresponding to (SA Service Area). In Figure 2, the service area 211 and a cell 201 match. Furthermore, the service area 212 includes a cell 202 and the cell 203. In FIG. 2, although three the number of HNB, not intended to limit the number of HNB.
[0034]
　First, with reference to FIGS. 2-9, an outline of the operation of the broadcasting system according to the first embodiment.
[0035]
　Broadcasting system according to the first embodiment, emergency bulletin message by two phases is to serve to UE 14. The first phase is the HNB management phase. The second phase is an information delivery phase.
[0036]
[HNB management phase]
　The HNB management phase, a phase in which manages the state of the HNB that normally occurs in the broadcasting system.
[0037]
　Figure 3 is a sequence diagram for explaining the HNB management phase. Referring to FIG. 3, the power of HNB13 is turned on and the HNB13 becomes available (operating state), HNB13 position information registration request message (HNBAP HNB REGISTER REQUEST; hereinafter, HNB REGISTER REQUEST denoted) HNB-GW 12 a to notify the (step S01)
[0038]
　At that time, HNB13 is in the position information registration request message, HNB specific LAC IE (Location Area Code Information Element; hereinafter referred to as LAC) and Service Area for Broadcast IE (hereinafter, referred to as Service Area for Broadcast) to set to. In Figure 3, LAC = 100 and Service Area for Broadcast = SA1 is set.
[0039]
　HNB-GW 12 that has received the message, performs a mapping of the notified LAC and Service Are for Broadcast, is registered in the database (storage unit) (step S02). Specifically, HNB-GW 12 is the HNB management table manages the correspondence of the service area HNB13 and the HNB13 corresponding to the notified LAC belongs. Figure 4 is a diagram showing an example of a HNB management table. In the above example, the first row entry in FIG. 4 is added.
[0040]
　Referring to Figure 3, after the mapping, HNB-GW 12 notifies the RESTART message defined in SABP (Service Area Broadcast Protocol) to CBC11 (step S03). At that time, received location information registration request message, the service area; If the first message received from the (SA Service Area), HNB-GW12 (in the example of FIG. 3 SA1) the service area available it was to the effect, to notify the CBC11. More specifically, HNB-GW 12, the corresponding service area (service area that has received the first message) service area list; described (SA List Service Area List), and transmits a RESTART message to CBC11. That, HNB-GW 12 notifies using the RESTART message CBC11 values ​​of Service Area for Broadcast IE as Service Area IE.
[0041]
　CBC11 is, the service area, which has been notified, is stored as the delivery destination of emergency early warning messages. CBC11 After receiving the RESTART message, the service area of ​​the notified SA the List, stored in a database of its own device (storage unit). For example, referring to FIG. 2, HNB13-2 and HNB13-3 has a Service Area for Broadcast of the same value, each using a HNB REGISTER REQUEST message, and notifies the HNB-GW 12. HNB-GW 12, when two HNB13-2 or 13-3 receives the message notifies the service area 212 becomes effective CBC11. CBC11, based on the notification, the service area 212 is managed as a delivery target for emergency bulletin message.
[0042]
　HNB-GW 12, if it is notified service area Service Area for Broadcast corresponding to the two HNB13 from CBC11, by referring to the HNB management table shown in FIG. 4, the two HNB13 the same service area it can be determined to be located in.
[0043]
　In addition, HNB-GW12 sends back (return) to HNB13 the HNB REGISTER ACCEPT message (step S04).
[0044]
　The femto system, the operation or failure of the user, the power of HNB is sometimes turned OFF, the connection is broken. In this case, as shown in FIG. 5, HNB13 notifies FAILURE message specified in SABP to HNB-GW 12 (step S11 ~ S13).
[0045]
　HNB-GW 12 that has received the notification performs state management of the service area HNB which has transmitted the FAILURE message belongs (step S14). HNB-GW 12 receives the FAILURE message, the state of HNB13 that has transmitted the message is set to "stop (no)", and registers the HNB management table (see FIG. 4). In FIG. 4, a service area "COMPLETE" is set is in a usable state, the service area "FAILURE" is set indicating that the unusable state.
[0046]
　HNB-GW 12 performs the management every time reception of FAILURE message, if all HNB13 residing in each service area has a stopped (not allowed), and registers the service area SA the List, and, set the state of the service area unavailable (FAILURE state), and notifies the CBC11. For example, in FIG. 4, the state of HNB13 corresponding to LAC = 100, 101 is shifted from "running" to "stop", the service area SA1 in which all LAC = 100 ~ 102 belongs is registered in the SA the List, and, the status of the service area SA1 is set to FAILURE, it is notified to the CBC11.
Specifically, HNB-GW 12 after the updating of the HNB management table, above notifies (SA1 is disabled), and notifies the CBC11 by sending FAILURE message (step S15).
[0047]
　Further, there is a case where restart HNB13 belonging to the service area notified as FAILURE state relative CBC11. For example, as shown in FIG. 6, one of HNB13, it transmits a RESTART message prescribed by SABP (step S21). In this case, HNB-GW 12, upon receiving the message, by setting the corresponding service area in HNB management table COMPLETE state, manages the status of the service area (step S22). For example, in FIG. 4, although the service area SA2 is in FAILURE state, when HNB13 corresponding to LAC = 200 or 201 has been restarted, the state of the service area SA2 is set to COMPLETE.
[0048]
　HNB-GW 12 after the updating of the HNB management table for CBC11, and set the available services area SA the List, and notifies the RESTART message (step S23). Incidentally, HNB-GW 12 is, after transmitting the RESTART message to CBC11, even if receiving a RESTART message from another HNB13 (step S24, S25), the message is discarded by the HNB-GW 12. Among a plurality of HNB13 residing in the service area, if one HNB13 is available, the state transition of the service area (the state transition from FAILURE to COMPLETE) is to complete.
[0049]
[Information delivery phase]
　Next, description will be made regarding the information delivery phase.
[0050]
　The information delivery phase, the emergency bulletin message when a huge earthquake or the like occurs, a phase to be distributed to each UE14.
[0051]

[0052]
　The CBC11 that receives the INFORMATION message, a should deliver early warning message area, creating a service area list (SA List). CBC11 sets the service area listed in WRITE-REPLACE REQUEST message defined by SABP, distributed to HNB-GW 12 (step S32).
[0053]
　HNB-GW 12, upon receiving the message, the response reception timer (hereinafter, simply referred to as timer) is started (step S33).
[0054]
　Next, HNB-GW 12 retrieves the HNB management table stored in the HNB management phase, WRITE-REPLACE REQUEST LAC service area and its corresponding matching the service area of ​​the service area list included in the message (SA the List) to identify (step S34). For example, CBC11 shall set the SA1 to service area list. In this case, referring to FIG. 4, the first line-service areas SA1 and LAC = 100 ~ 102 described in the third line is identified.
[0055]
　Next, HNB-GW 12, based on the information specified above, the WRITE-REPLACE REQUEST message transmitted to each HNB13 (step S35).
[0056]
　HNB13 having received the message, if the reception is performed normally, it returns the WRITE-REPLACE COMPLETE message to the HNB-GW 12 (step S36). At that time, HNB13 is the Number of Completed the List, the corresponding service area (service area belongs itself; in the example of FIG. 7 SA1) is set and returns the message.
[0057]
　HNB13 is, to UE14 under by a paging (PAGING), to notify the emergency bulletin message (step S37).
[0058]
　HNB-GW 12, in response to reception of WRITE-REPLACE COMPLETE message, it manages the status of the broadcasting for HNB13 (step S38). Specifically, HNB-GW 12 is a broadcasting management table manages broadcast delivery status for each service area.
[0059]
　Figure 8 is a diagram showing an example of the broadcast distribution management table. In FIG. 8, a service area that has been set to "COMPLETE" is a service area of ​​broadcasting has been completed (successful), service area "FAILURE" is set broadcast delivery is not completed (or failed) which is the service area.
[0060]
　HNB-GW 12 (in the example above SA1) service area initially to receive a WRITE-REPLACE COMPLETE message from, and sets the service area to receive complete state (COMPLETE state). Further, HNB-GW 12 registers the service area Number of Completed List.
[0061]
　HNB-GW 12, the broadcasting state to all service areas under its, if a transition in the reception completion status (COMPLETE state) while the timer started, the timer is stopped (step S39).
[0062]
　Thereafter, HNB-GW 12 is toward the CBC11, returns the WRITE-REPLACE COMPLETE message (step S40). At that time, the WRITE-REPLACE COMPLETE message, Number of Completed List the service area SA1 is set is registered.
[0063]
　CBC11 receiving the message, to the CBE10, it returns the ACK (Step S41).

That is, the broadcasting controller 73, a service area that is set in the service area list, searches the HNB management table, identifies the corresponding LAC. By LAC is specified, HNB13 is identified that need to deliver emergency bulletin message.
[0081]
　If the service area is registered (step S103, Yes branch), the broadcasting controller 73 sends a WRITE-REPLACE message to all the HNB13 identified (HNB13 of the corresponding service area under) (step S104) to repeat the processing (loop 2).
[0082]
　On the other hand, if it is not registered the service area (step S103, No branch), the broadcasting controller 73, a service area that is set in the service area list, and registers the HNB management table and broadcasting management table ( step S105). For example, referring to FIGS. 4 and 8, the broadcasting controller 73 is notified from the service area CBC11 according to the service area SA4, the service area SA4 is not registered in the HNB management table and broadcasting management table if not, create an entry that corresponds to the service area SA4, to add to the above two tables.
[0083]
　Also, the broadcasting controller 73 the status of the service area for which the additional in broadcasting management table is set to FAILURE (step S106), and registers the Cause value (step S107).
[0084]
　Incidentally, in step S101, when receiving the WRITE-REPLACE message other than the message (KILL / LOAD QUERY / Message STATUS QUERY / RESET), multicasting control unit 73, a message in step 104, the other messages to execute the process is changed to.
[0085]
　If a response is received from HNB13, multicasting control unit 73 executes the process shown FIGS. 13 to 16.
[0086]
　Referring to FIG. 13, the broadcasting controller 73 receives the WRITE-REPLACE COMPLETE or WRITE-REPLACE FAIRURE message from HNB13 (step S201).
[0087]
　Thereafter, the broadcasting controller 73, the timer determines whether or not the start (step S202). If the timer is being activated (step S202, No branch), the process ends.
[0088]
　If the timer is being activated (step S202, Yes branch), the processing after step S203 is executed.
[0089]
　Broadcasting control unit 73, at step S203, the received message is judged whether the WRITE-REPLACE COMPLETE message (step S203). If WRITE-REPLACE COMPLETE message (step S203, Yes branch), the broadcasting controller 73 determines whether the corresponding service area of ​​the message is set to COMPLETE (step S204).
[0090]
　If it sets to COMPLETE (step S204, Yes branch), the broadcasting controller 73 registers the corresponding service area to the Number of Completed List (step S205). Thereafter, the broadcasting controller 73, a broadcasting state of the corresponding service area is set to COMPLETE (step S206).
[0091]
　Broadcasting control unit 73, the received message is, if the WRITE-REPLACE COMPLETE message (step S203, No branch), the WRITE-REPLACE FAILURE message Number of Completed the List determines whether or not it is registered ( step S207).
[0092]
　If on the list (step S207, Yes branch), the broadcasting controller 73 registers the corresponding service area to the Number of Completed the List (step S208).
[0093]
　If it is not registered in the list (step S207, No branch), the broadcasting controller 73 determines whether or not the broadcasting status of the corresponding service area is set to COMPLETE (step S209). If COMPLETE not is set (step S209, No branch), the broadcasting controller 73, the Cause value of FAILURE message, and temporarily stores (step S210).
[0094]
　Thereafter, the broadcasting controller 73, messages received from all HNB13 working under the corresponding service area, determines whether the WRITE-REPLACE FAILURE message (step S211).
[0095]
　If the received message is a WRITE-REPLACE FAILURE message, the broadcasting controller 73 registers the corresponding service area FAILURE LIST IE, it sets the state of the broadcasting management table FAILURE (step S212, S213 ). The temporarily stored Cuase value is set (step S214).
[0096]
　In step S215, the broadcasting controller 73 For all service areas, determines whether or not the broadcasting state is set. If the state is set (step S215, Yes branch), the broadcasting controller 73 determines whether FAILURE LIST to FAILURE service area set exists (step S216).
[0097]
　If there is configured service areas FAILURE (step S216, Yes branch), the broadcasting controller 73, the timer is stopped (step S217), and transmits the WRITE-REPLACE FAILURE message to the CBC11 (Step S218) .
[0098]
　If the service area is present which is set to FAILURE (step S216, No branch), the broadcasting controller 73, the timer is stopped (step S219), and transmits the WRITE-REPLACE COMPLETE message to the CBC11 (step S220 ).
[0099]
　Incidentally, when receiving a WRITE-REPLACE COMPLETE and FAILURE message other than (KILL / LOAD QUERY / Message STATUS QUERY), the broadcasting controller 73, the message in step S201, S203, S207, S211, S218, S220 , executes processing to change to the other messages.
[0100]
　Figure 14 is a broadcasting control unit 73 is a flowchart of a case of receiving the LOAD QUERY COMPLETE or LOAD QUERY FAIRURE message from HNB13. Broadcasting control unit 73, even if the received message according to the LOAD QUERY, performs reception at essentially the same operation of the message according to the WRITE-REPLACE shown in FIG. 13. The points of difference, step 221 in FIG. 14, S223, S227, S231, S238, message in S240, the point where the LOAD QUERY message at step S225 and S228, a list for registering the corresponding service area Radio Resource Loading Loading is that the change in the List.
[0101]
　Figure 15 is a broadcasting control unit 73 is a flowchart of a case of receiving the RESET COMPLETE or RESET FAIRURE message from HNB13. Broadcasting control unit 73, even if the received message according to the RESET, perform reception at essentially the same operation of the message according to the WRITE-REPLACE shown in FIG. 13. The points of difference, message in step 261, S263, S271, S278, S280 of FIG. 15, the point at which the RESET message, at step S265, a point list for registering the corresponding service area is SERVICE AREA IE, processing corresponding to step S207 and S208 is that it does not exist.
[0102]
　Figure 16 is a flow chart showing an example of the operation of the broadcasting controller 73 when the activated timer expires.
[0103]
　Broadcasting control unit 73, the timer expires (step S301) Then, the processes of steps S302 ~ S308, repeated for the number of service area state is not determined (process of the loop 3).
[0104]
　Broadcasting control unit 73, after the timer expires, determines whether there is a response from the HNB13 under (step S302).
[0105]
　If there is no response (step S302, Yes branch), the broadcasting controller 73 registers the corresponding service area FAILURE LIST IE, to set the state of the service area FAILURE (step S303, S304) . Broadcasting control unit 73 sets the Cause value is set to FAILURE message (step S305).
[0106]
　On the other hand, if a response is received (step S303, No branch), the broadcasting controller 73 registers the corresponding service area FAILURE LIST IE, to set the state of the service area FAILURE (step S306 , S307). Broadcasting control unit 73 sets the temporary set Cause value according FAILURE message (step S308).
[0107]
　Thereafter, the broadcasting controller 73 toward the CBC11, transmits the WRITE-REPLACE FAILURE (step S309).
[0108]
　Referring to FIGS. 17 and 18, HNB-GW 12 (multicasting control unit 73) receives any one from WRITE-REPLACE COMPLETE message HNB13 included in the service area under the state of the service area setting the COMPLETE (step S407, S428).
[0109]
　Thereafter, HNB-GW 12 is a corresponding service area, registered in the Number of Completed the List, and transmits the WRITE-REPLACE COMPLETE message to the CBC11 (step S410, S431).
[0110]
　Thus, the response from HNB13 after the response has been made to CBC11 from HNB-GW 12 is not considered. That, HNB-GW 12, the (step S432 of step S411, S412 and FIG. 18 in FIG. 17) if the broadcasting state of each service area COMPLETE, to ignore the received message. However, HNB-GW12 is, the timer is running, and, broadcasting the status of the service area is not the COMPLETE, to wait for a response from the other HNB13.
[0111]
　Referring also to FIG. 19, upon receiving a WRITE-REPLACE FAILURE message from all HNB13 included in the service area under, HNB-GW 12 sets a broadcasting state of the services areas FAILURE (Step S449) . Thereafter, the CBC11 from HNB-GW12, WRITE-REPLACE FAILURE message is transmitted (step S452).
[0112]
　Referring also to FIG. 20, while the timer start, even if the response from the HNB13 included in the service area under the not obtained, HNB-GW 12 sets the state of the service area FAILURE (step S467).
[0113]
　Furthermore, HNB-GW 12, even when receiving the return of COMPLETE message from HNB13, if the timer is already stopped (expiration), ignoring the received message. Alternatively, HNB-GW 12 is, when transferring the message to HNB13, if there is no HNB13 transferable to the service area under the condition of the corresponding service area is set to FAILURE, is notified to the CBC11.
[0114]
Operation of the service area management unit]
　Next, the operation of the service area management unit 74 in the case of receiving the signals of the above Class2, with reference to FIGS. 21 to 23, will be described.
[0115]
　Referring to FIG. 21, the service area management unit 74 receives a RESTART message defined by SABP from HNB13 (step S501). The service area management unit 74, sets the state of HNB13 corresponding to the received LAC to "operation (Yes)" reflects the HNB management table (step S502).
[0116]
　Service area management unit 74, sent to the CBC11 set the broadcasting state of the service area FAILURE, and is transmitted to when it is not transmitting a RESTART message (step S503, Yes branch), a RESTART message to CBC11 (step S504).
[0117]
　Note that the message received from the service area is registered, if the message from the first HNB13, the service area management unit 74, add the appropriate SA in the SA the List by RESTART message SABP, transferred to CBC11. Also, the already set the appropriate SA in the SA the List, if the sent a RESTART message to CBC11, HNB-GW12 discards the RESTART message.
[0118]
　Referring to FIG. 22, the service area management unit 74 receives the FAIULRE message from HNB13 (step S511). In this case, the service area management unit 74, sets the state of HNB13 corresponding to the received LAC to "stop (poor)" reflects the HNB management table (step S512). As a result, if the HNB13 available in the same service area becomes absent (step S513, No branch), the service area management unit 74 sends a FAILURE message to CBC11 (step S514).
[0119]
　The service area management unit 74, HNB13 other than the above is when it becomes unavailable, transmits a FAILURE message to CBC11 (see FIG. 23).
[0120]
　Referring to FIG. 23, when receiving the HNB DEREGISTER If the message has been sent (if lost connection between HNB-GW and HNB) or HNB from HNB DEREGISTER message to (step S521), the state of the HNB13 is " is set to stop (not allowed) "(step S522). Further, as a result, HNB13 available in the same service area when a absence (step S523, No branch), the service area management unit 74 sends a FAILURE message to CBC11 (step S524).
[0121]
　As described above, in the broadcasting system according to the first embodiment, a relay device located in the middle of the CBC11 and HNB13 is (HNB-GW 12), manages related to HNB13 belonging to the service area and the service area . In addition, HNB-GW12 performs control related to the operation state and the broadcasting of the HNB, the management. In other words, CBC11 is complicated control such as HNB-GW 12 is responsible, the management is not necessary to (a state management of all HNB), it is sufficient to perform the state management of the service area units. As a result, the load for delivering Early warning message to HNB13 in CBC11 is reduced.
[0122]
　Save More specifically, as described with reference to FIG. 3, the HNB registration phase, when a new HNB13 has been added, using a HNB REGISTER REQUEST message, associates the LAC and Service Area for Broadcast to. That, HNB-GW 12 is HNB13 identified by LAC is managed so as to belong to one of the Service Area for Broadcast. Furthermore, HNB REGISTER REQUEST message, if it is the first of the REGISTER REQUEST message acquired from the service area, HNB-GW 12 is the Service Area IE of RESTART message specified by SABP, setting the Service Area for Broadcast IE that is, to notify the delivery destination of emergency early warning message to the CBC11.
[0123]
　Corresponding results in more HNB-GW 12, the broadcasting system according to the first embodiment, it becomes possible to register multiple HNB13 one service area.
[0124]
　Also, the broadcasting system according to the first embodiment, upon receipt of the early warning message from CBC11, the SA the List included in the message, by referring to the mapping information of the service area and HNB, a plurality of the message can be delivered to the HNB13.
[0125]
　Furthermore, broadcasting system according to the first embodiment, after transmitting the emergency bulletin message from CBC11 from HNB-GW 12 to HNB13, manages the response message from HNB13 a service area basis, a response message to the CBC11 returnable (it corresponds to the signal of the Class1).
[0126]
　Furthermore, broadcasting system according to the first embodiment, after receiving a message from HNB, manages HNB in ​​service area units, (it corresponds to the signal of the Class2) can send messages to the CBC11.
[0127]
　Incidentally, the broadcasting controller 73 and the service area management unit 74, the onboard computer to HNB-GW 12, using the hardware can be realized by a computer program for executing the processing described above.
[0128]
　Thus, CBC11 is, without managing HNB13 state such as over hundreds of thousands, by the management of the service area unit, can deliver emergency bulletin message to UE14. That, HNB-GW 12 is, on behalf of the CBC11, for managing the state of HNB13, CBC11 will it is sufficient to manage only the status of the service area, the load drops.
[0129]
　Also, when delivering emergency bulletin message, CBC11, create a list that contains all of HNB13, such as over hundreds of thousands, it becomes unnecessary to be delivered. That, CBC11 is the number corresponding to the number of service areas, may be delivered a message. Further, by the above-mentioned matters, the number of signals between the HNB-GW 12 and CBC11 is reduced. Specifically, specifications on, since possible number of cells of up to 65535 to one service area registration can reduce the number of signals to one-up 65535 minutes.
[0130]
　Incidentally, configuration and operation of the broadcasting system described in the first embodiment is exemplary, and various modifications are possible. For example, HNB-GW is a service area list (SA the List) obtained from CBC11, techniques to associate the HNB13 is changed to the use of the LAC, even using Cell ID (Identifier) ​​and RAC (Routing Area Code) good.
