Background Art
[0002]
15 In recent years, a method of optimizing a setting of each proc essing node
which makes up a mobile communication system has been demanded. 3GPP
proposes a method of optimizing network processing according to use
characteristics of a mobile communication terminal (Non-Patent Literature 1) .
For example, network proces sing may be executed with respect to a terminal
20 located by being fixed to a specific location to reduce control processing related to
a move. More specifically, an interval at which the terminal executes position
registration may be set longer than a predetermined time. Furthermore, when a
mobile communicat ion terminal is a terminal which allows a delay, network
processing may be executed to transmit data to the mobile terminal by controlling
25 a communication time and avoiding a timing at which a data
transmission/reception amount comes to a peak.

network system configuration as i llustrated in Fig. 19 to execute the above
30 network processing (Non-Patent Li terature 2) . The network system in Fig. 19

Description of Embodiments
[0015]
20 (First Embodiment )
Embodiments of the present invention wil l be described below with
reference to the drawings. A configurat ion example of a mobi le communication
system according to the first embodiment of the present invention will be
described with reference to Fig. 1. The mobile communicat ion system in Fig. 1
25 has a detection server 40, a control apparatus 30 and a processing node 20 . A
mobile terminal 10 communicates with other mobile terminals and a server
apparatus through the mobile communication system. Wireless communication is
used for communication between the mobile terminal 10 and the mobile
communicat ion system. The processing node 20 may be, for example, a radio
30 base stat ion 21 or a mobility management ent ity 22. The mobility management
entity 22 and the control apparatus 30 make up a core network 50 managed by a
mobile communicat ion business operator.
[0016]
The mobile terminal 10 may be a mobile telephone terminal, a smartphone
8
terminal or a notebook personal computer, or may be transport ing means such as a
car or a train in which a communication function is installed or a machine such as a
watch which a user puts on and in which a communication function is installed.
Alternatively, the mobile terminal 10 may be an apparatus which less frequently
moves such as an automatic vending machine in which a communication functio5 n
is installed.
[0017]
The detection server 40 detects a characteri stics change of a mobile
communicat ion apparatus based on an event not ice transmitted from the mobile
10 terminal 10. The detection server 40 may be arranged in the core network 50
managed by the mobi le communication business operator, or may be arranged
outside the core network 50 to be managed by a third party other than the mobile
communicat ion business operator.
[0018]
15 An event notice may be, for example, information of a user operation of the
mobile terminal 10 or sensor information detected by the mo bile terminal 10.
When, for example, the mobile terminal 10 is a car, the operation information may
be information indicating that the user has turned on or off an engine of the car.
Alternatively, the operation information may be information indicating that the
20 user has started or stopped operat ing a car navigation system installed in the car or
information indicating a position set as a destination . Alternatively, the
operation information may be information indicating that the user has activated a
moving image browsing software installed in a mobile telephone terminal . The
sensor information may be information obtained by detecting environment
25 information of the surroundings or information related to a temperature of the
surroundings when, for example, a temperature sensor is mounted on a mobile
telephone terminal . Furthermore, the sensor information may be velocity
information of a mobile telephone when, for example, an accelerat ion sensor is
mounted on a mobile telephone terminal .
30 [0019]
A characteristics change may be, for example, a behavior change of the
mobile terminal 10 and a change of a communication situation of the mobile
terminal 10. When, for example, the mobile terminal 10 is a car and an event
notice transmit ted from the mobile terminal 10 notifies that an engine is turned off,
9
the detection server 40 may detect a behavior change indicating that the car has
stopped moving. Furthermore, when notified that the engine is turned on, the
detection server 40 may detect a behavior change indicating that the car has started
moving. When notification of an event indicating that the user has act ivated the
moving image browsing software of the mobile telephone terminal is transmitted5 ,
the detection server 40 may detect a change of a communicati on situation
indicating that the user is going to execute broadband communication from now.
Furthermore, when notification of an event indicating that the user has performed
an operation of starting a voice call of the mobile telephone terminal is transmi tted,
10 the detection server 40 may detect a change of a communication situation
indicating that the user is going to execute narrowband communication from now.
[0020]
As described above, the detection server 40 receives an event notice, and
extracts a characteristics change of the mobile terminal 10 corresponding to the
15 received event notice.
[0021]
The control apparatus 30 determines control content s in the mobile
terminal 10 based on the characteristics change of the mobile terminal 10 detected
by the detection server 40, and sets the determined control content s to the
20 processing node 20 which executes data transfer processing between the mobile
terminal 10 and another mobile terminal or control processing related to data
transfer.
[0022]
The control contents in the mobile terminal 10 may be, for example, control
25 of changing a paging area of the mobile terminal 10 or control of allocating a
communicat ion band to the mobile terminal 10. When, for example, the detection
server 40 detects a characteri stics change indicating that the mobile terminal 10
has stopped, the control apparatus 30 may perform control to narrow the paging
area of the mobile terminal 10 to a cell size . A paging area refers to an area for
30 calling the mobile terminal 10 when, for example, processing of receiving a call at
the mobile terminal 10 is executed. When the mobile terminal 10 stops, it is
possible to narrow a call range and, consequently, narrow the paging area to a cel l
area in which the mobile terminal 10 exists and which is configured by a base
station. Furthermore, when detecting a characteristics change indicating that the
10
mobile terminal 10 has started to move, the control apparatus 30 may perform
control to widen the paging area of the mobile terminal 10 in units of prefectures
to enable the mobile terminal 10 to be reliably called.
[0023]
In another example, when the detection server 40 detects a characteristic5 s
change indicating that the mobile terminal 10 has executed broadband
communicat ion, the control apparatus 30 may perform control to secure, for
example, 10 Mbps as a bandwidth to be allocated to the mobile terminal 10 .
Furthermore, when the detection server 40 detects a characterist ics change
10 indicating that the mobile terminal 10 has executed narrowband communication,
the control apparatus 30 may perform control to secure, for example, 1 Mbps as a
bandwidth to be allocated to the mobile terminal 10 .
[0024]
The processing node which executes data transfer processing between the
15 mobile terminal 10 and another mobile terminal may be, for example, the radio
base stat ion 21 or a switch (not illustrated) . The processing node which executes
control processing related to data transfer between the mobile terminal 10 and
another mobile terminal may be, for example, the mobility management ent ity
(MME) 22 which executes movement control of the mobile terminal 10 or a
20 subscriber informat ion server (HLR or HSS: Home Subscriber Server) .
[0025]
As described above, by using the mobile communication system in Fig, 1 ,
the detection server 40 connected to the core network 50 can detect a
characteristics change of the mobile terminal 10 based on an event notice
25 transmitted from the mobile terminal 10. Furthermore, the control apparatus 30
arranged in the core network 50 can change contents to be set to the processing
node 20 per mobile terminal according to the detected characteristics change .
Consequently, it is possible to configure a network according to characteristics of
each mobile terminal , and adequately distri bute network resources or radio
30 resources.
[0026]
Next, a configurat ion example of the detection server 40 according to the
first embodiment of the present invention will be descried with reference to Fig. 2 .
The detection server 40 has an interface 41, a detecting uni t 42, a characteristics
11
change detecting DB 43 and a notifying unit 44.
[0027]
The interface 41 transmits and receives data to and from the control
apparatus 30. Although Fig. 2 illustrates a configuration where the detection
server 40 has one interface 41, the detection server 40 may have a plurality o5 f
interfaces to transmit and receive data to and from the radio base station 21 or the
mobility management ent ity 22.
[0028]
The detecting unit 42 receives an event notice transmitted from the mobile
10 terminal 10, through the interface 41. The detecting uni t 42 extracts a
characteristics change corresponding to the received event notice using the
characteristics change detecting database (DB) 43. Hereinafter, a configuration
example of the characteristics change detecting DB 43 wil l be described with
reference to Fig. 3.
15 [0029]
The characteristics change detecting DB 43 in Fig. 3 associates and
manages information related to event contents for which a notification is to be
transmitted, and information related to characteristics change contents.
Furthermore, the characteristics change content s are classified into a
20 characteristics type and characteristics content s corresponding to the
characteristics type. For example, the event contents include engine stop, engine
activation, navigation start , navigation stop, multimedia use start and multimedia
use end. Event contents indicating engine stop are associated with a move as a
characteristic type and characteristics change content s indicating stop as contents.
25 That is, when an event not ification indicating that an engine has stopped is
transmitted from the mobile terminal 10, the detecting unit 42 detects that the
mobile terminal 10 has stopped moving. When an event notification indicating
that the engine has been activated is transmitted from the mobi le terminal 10, the
detecting uni t 42 detects that the mobile terminal 10 has started to move.
30 [0030]
Furthermore, when an event notification indicating that navigation has
started is transmitted from the mobile terminal 10, the detecting unit 42 detects
that a communication interval such as an information distribution interval for the
navigation system is five minutes. When an event notification indicating that
12
navigation has ended is transmi tted from the mobi le terminal 10, the detecting unit
42 detects that a communication interval such as an information distribution
interval for the navigation system is one hour. Furthermore, when an event
notification indicat ing that use of multimedia has started has been transmitted
from the mobile terminal 10, the detecting unit 42 detects that the mobile termina5 l
10 uses a communication band up to 10 Mbps . When an event notification
indicating that use of the multimedia ends has been transmitted from the mobile
terminal 10, the detecting unit 42 detects that the mobile terminal 10 uses a
communicat ion band up to 1 Mbps .
10 [0031]
Referring back to Fig. 2, when the characteristics change corresponding to
the event contents notificat ion transmi tted from the mobile terminal 10 is extracted,
the detecting unit 42 outputs the extracted characteristics change to the notifying
unit 44.
15 [0032]
The not ifying unit 44 outputs the characteristics change output from the
detecting uni t 42 to the control appa ratus 30 through the interface 41.
[0033]
Next, a configurat ion example of the control apparatus 30 according to the
20 first embodiment of the present invention will be described with reference to Fig. 4 .
The control apparatus 30 has interfaces 31 and 32, a control uni t 33, a NW
(Network) control policy DB 34 and a notifying unit 35 .
[0034]
The interface 31 transmits and receives data to and from the detection
25 server 40. The interface 32 transmits and receives data to and from the
processing node 20. When the radio base station 21 and the mobility management
entity 22 transmit and receive data using different interfaces, different interfaces
may be used per apparatus of a communicating party which transmits and receives
data.
30 [0035]
The control uni t 33 receives information related to the characteristics
change of the mobile terminal 10 output from the detection server 40, through the
interface 31. Furthermore, the control unit 33 may output the event notice
received from the mobile terminal 10 through the interface 32, to the detection
13
server 40 through the interface 31. The control unit 33 extracts a NW control
policy corresponding to the received characteristics change using the NW control
policy DB 34. Hereinafter, a configuration example of th e NW control policy DB
34 will be described with reference to Fig. 5.
[00365 ]
The NW control policy DB 34 in Fig. 5 associates and manages information
related to characteristics change content s and information related to a NW control
policy. Information related to characteristics change content s is the same as
characteristics change content s in the characteristics change detecting DB 43.
10 Informat ion related to a NW control policy is classified into a control type and
control contents corresponding to the control type.
[0037]
When, for example, the detection server 40 transmits a notification of
information indicating a move as a characteristics type and move stop as
15 characteristics change content s, the control unit 33 determines a NW control policy
of sett ing a size of a paging area related to the mobile terminal 10 to a cell si ze
managed by one base stat ion, and determines a position registration interval of the
mobile terminal 10 as every three hour s. Furthermore, when the detection server
40 transmits a notification of information indicating a move as a characteristics
20 type and a move start as characteristics change content s, the control unit 33 may
determine a NW control policy of setting a size of a paging area related to the
mobile terminal 10 to a size in units of prefectures, and determine a posit ion
registration interval of the mobile terminal 10 as every ten minute s.
[0038]
25 That is, when the mobile terminal 10 stops moving, a movement range
narrows, so that it is also possible to set a narr ow paging area. Consequently, it is
possible to set only a cell area configured by one base station to a paging area. In
contrast with this, when the mobile terminal 10 starts moving, a movement range
widens. Hence, it is necessary to widen the paging a rea to enable the mobile
30 terminal 10 to be reliably called. Consequent ly, for example, all cell areas
configured by base stations in the same prefecture may be set to a paging area.
Furthermore, when the mobile terminal 10 stops moving, the mobile terminal 10 is
highly likely to exist in the same position registration area and therefore a long
position registration interval may be set and, when the mobile terminal 10 starts
14
moving, the mobi le terminal 10 is highly l ikely to exist in posit ion registration
areas which differ as the time passes and therefore a short posit ion registration
interval may be set .
[0039]
Still further, when the detection server 40 transmits a notification o5 f
information indicating a communication interval as a characteristics ty pe and five
minutes as characteristics change content s, the control unit 33 may set an interval
at which the mobile terminal 10 operates in a normal power mode to five minutes
and set an intermi ttent reception interval to 0.128 s. The mobile terminal 10
10 operates in a power-saving mode when the mobile terminal 10 does not operate in
the normal power mode. When the detect ion server 10 transmi ts a not ification of
information indicating a communication interval as a characteristics type and one
hour as characteristics change content s, the control unit 33 may set an interval at
which the mobile terminal 10 operates in the normal power mode to one hour and
15 set the intermittent reception interval to 128 s.
[0040]
Furthermore, when the detection server 40 transmits a notification of
information indicating a communication band as a characteristics type and up to 10
Mbps as characteristics change content s, the control unit 33 may set to a maximum
20 allowable band to be allocated to the mobi le terminal 10 to 10Mbps. When the
detection server 40 transmi ts a notification of informat ion indicating a
communicat ion band as a characteristics type and up to 1 Mbps as characteristics
change contents, the control unit 33 may set a maximum allowable band to be
allocated to the mobi le terminal 10 to 1Mbps.

Referring back to Fig. 4, the NW control policy extracted using the NW
control policy DB 34 is output to the notifying unit 35. The notifying unit 35
outputs the NW control pol icy to the processing node 20 through t he interface 32.
[0042]
30 Next, a flow of processing of registering a mobile terminal which is a
characteristics change monitoring target , in the detection server according to the
first embodiment of the present invention will be described with reference to Fig. 6.
First, the mobile terminal 10 transmits a connection request to the radio base
station 21 (S11) . When, for example, the mobile terminal 10 is powered on, the
15
connection request is executed. A terminal identifier of the mobile terminal 10 is
also included in a message related to the connect ion request . The mobi le terminal
identifier is, for example, a model number, a telephone number, a MAC (Media
Access Control) address or an IP ( Internet Protocol) address allocated to the
mobile terminal 105 .
[0043]
Next, when the connection request from the mobile terminal 10 is executed,
NW connection processing is performed between the mobile terminal 10, the radio
base stat ion 21 and the mobility management entity 22 (S12) . The NW
10 connection processing is directed to providing a state where communicat ion can be
executed between the mobile terminal 10 and the radio base stat ion 21 and is
general processing in mobile communication, and therefore will not be described
in detail .
[0044]
15 Next, the mobility management entity 22 transmits a message related to the
connection request transmi tted from the mobile terminal 10, to the control
apparatus 30 (S13). The terminal identifier of the mobile terminal 10 is also
included in the message transmitted from the mobil ity management entity 22 to the
control apparatus 30 and the message is related to the connection request .
20 [0045]
Next, the control apparatus 30 transmits a characteristics change
monitoring request message to the detection server 40 to set the mo bile terminal 10
to a characteristics change monitoring target terminal in the detection server 40
(S14). Furthermore, the control apparatus 30 includes the terminal identifier of
25 the mobile terminal 10 in the characterist ics change monitoring request mes sage
and transmits the characteristics change monitoring request message to clarify the
mobile terminal 10 requested as a monitoring target terminal .
[0046]
Next, the detection server 40 starts moni toring the characteristics change of
30 the mobile terminal 10 corresponding to the terminal identifier set to the
characteristics change monitoring request message (S15) .
[0047]
Next, a flow of processing of setting a NW control policy according to the
first embodiment of the present invention will be describ ed with reference to Fig. 7.
16
The processing of set ting a NW control policy is executed after the processing of
registering the mobile terminal in Fig. 6.
[0048]
First, the mobile terminal 10 transmits an event notice to the detection
server 40 (S21) . The event notice includes the terminal identifier of the mobil5 e
terminal 10 and contents of an event which occurs . Next, the detection server 40
detects a characterist ics change of the mobile terminal 10 corresponding to the
event contents in the notification (S22). Subsequently, the detection server 40
transmits a notification about the detected characteristics change to the control
10 apparatus 30 (S23) . The terminal identifier of the mobile terminal 10 is also
included in the message in which a notificat ion about the characteristics change is
transmitted from the detection server 40 to the control apparatus 30 .
[0049]
Next, the control apparatus 30 determines NW control policy content s
15 corresponding to the characteristics change which the detect ion server 40 has
transmitted a notification about (S24) . Next, the control apparatus 30 transmits a
notification about the determined NW control policy to the mobility management
entity 22 (S25). The control apparatus 30 also notifies the mobility management
entity 22 about the NW control policy and the mobile terminal ident ifier of the
20 mobile terminal 10.
[0050]
Next, the mobility management ent ity 22 changes the NW control policy
related to the mobile terminal 10, to the NW control policy which the control
apparatus 30 has transmitted a notification about (S26).
25 [0051]
In this regard, although a notification about the NW control policy is
transmitted to the mobility management entity 22 in step S25, the notificat ion
about the NW control policy may be transmitted to the radio base stat ion 21. For
example, the control apparatus 30 may determine a notice destination according to
30 a NW control policy by transmitting a notification about the NW control policy to
the mobili ty management entity 22 when a control type is a NW control policy
related to a paging area, and by transmitting a notification about the NW control
policy to the radio base stat ion 21 when the control type is a NW control policy
related to a maximum allowable band. Furthermore, the control apparatus 30 may
17
transmit a notification about a NW control policy which needs to be set , to another
apparatus such as a switch which makes up the core network in addition to the
radio base station 21 and the mobility management ent ity 22 .
[0052]
As described above, by using the mobile communication system accordin5 g
to the first embodiment of the present invention, the detection server 40 can
receive information related to event content s from the mobile terminal 10. The
detection server 40 can detect a characteristics change based on information
related to event contents, and the control apparatus 30 can determine a NW control
10 policy based on the characteristics change . Consequently, the mobile
communicat ion system can set an optimal NW control policy according to the
characteristics change in the mobile terminal 10.
[0053]
Furthermore, although an example has been described in the first
15 embodiment of the present invention where the detection server detects a
characteristics change based on a notificat ion of event contents transmitted from
the mobile terminal 10, the detection server 40 may detect a characteristics change
by analyzing content s of data transmitted from the mobile terminal 10 . The
detection server 40 may detect a characteristics change u sing data transmitted from
20 the mobile terminal 10 as word information disclosed in a document such as an
electronic mail . Alternat ively, the detect ion server 40 may detect a
characteristics change by analyzing video data and audio data.
[0054]
Furthermore, the detection server 40, the control apparatus 30 and the
25 processing node 20 may be associated with apparatuses discussed by 3GPP in Fig.
19 as follows. For example, the detection server 40 may correspond to a MTC
Application 110, the control apparatus 30 may correspond to a MTC- IWF 106, a
CDF/CGF (CDF/Charging Gateway Function) 107, a SMS-SC/ IP-SM-GW 108 and
a MTC Server 109, and a processing node may correspond to a SGSN/MME 103, a
30 GGSN/S-GW+P-GW 104 and a HLR/HSS105.
[0055]
(Second Embodiment )
Next, a configurat ion example of a detection server 40 according to the
second embodiment of the present invention will be described with reference to
18
Fig. 8. The detection server 40 has an interface 41, a detecting unit 42, a
characteristics change detecting DB 43, a notifying unit 44 and a terminal specific
detection item DB 45. The components other than the terminal specific detection
item DB 45 are the same as those in Fig. 2, and therefore will not be described in
detail 5 .
[0056]
The terminal specific detection item DB 45 manages, per mobile terminal,
items related to a characteristics change of a mobile terminal which the detection
server 40 needs to detect . Hereinafter, a configuration example of the terminal
10 specific detect ion item DB 45 according to the second embodiment of the present
invention will be described with reference to Fig. 9 .
[0057]
The terminal specific detection item DB 45 associates and manages a
terminal identifier and a characteristics type regarding which a notification needs
15 to be transmit ted. The terminal identifier may be, for example, a model number, a
telephone number, a MAC address or an IP address allocated to each mobile
terminal . In Fig. 8, for example, terminal identifiers identified as terminals 1 to 3
are managed. The characteristics type which needs to be detected is the same as
the characteristics type described with reference to Figs. 3 and 5 .
20 [0058]
In Fig. 8, move, a communicat ion interval and a communicat ion band are
associated as characteristics type s with the terminal 1. A move is associated as a
characteristics type with the terminal 2, and a communicat ion interval and a
communicat ion band are associated as characteristics types with the terminal 3 .
25 That is, for example, only the characterist ics chan ge related to a move is detected
for the terminal 2. Hence, in an example in Fig. 3, although the terminal 2 detects
a characteristics change and executes processing when a notification of event
contents indicat ing engine stop or engine activat ion is transmit ted, the terminal 2
does not execute processing of detecting a characteristics change even when a
30 notification of event contents indicat ing navigation start and end or mul timedia
use start and use end is transmitted.
[0059]
Next, a flow of processing of registering a mobile terminal which is a
characteristics change monitoring target , in a detection server according to the
19
second embodiment of the present invention will be described with reference to
Fig. 10. Steps S31 to S33 and step S35 are the same as steps S11 to 13 and step
S15 in Fig. 6, and therefore will not be described.
[0060]
In step S34, a control apparatus 30 transmi ts a not ification of 5 a
characteristics change monitoring request message to the detect ion server 40 .
The characteristics change monitoring request includes information related to a
terminal identifier of a mobile terminal 10 and a characteristics type which needs
to be detected.
10 [0061]
Although Fig. 10 illustrates an example where the mobile terminal 10
transmits a noti fication of information related to a characterist ics type which needs
to be detected, information related to a characteristics type which needs to be
detected may be acquired from a subscriber server which manages subscriber
15 information of a plurality of mobile terminals. In this case, information related
to a characteristics type which needs to be detected per mobile terminal is
registered in advance in the subscriber server.
[0062]
Next, a flow of processing of detect ing a characteristics change in th e
20 detection server 40 according to the second embodiment of the present invention
will be described with reference to Fig. 11. First, the detecting unit 42 receives
an event notice from the mobile terminal 10 (S41) . Next, the detecting unit 42
checks a terminal identifier included in the event notice, and identifies a mobile
terminal which is a transmission source of the event notice (S42) . Next, the
25 detecting uni t 42 determines whether or not event contents indicate the event
related to the characterist ics type managed by being associated with the identified
mobile terminal in the terminal specific detection item DB 45 (S43) . When
determining that event content s regarding which a notification has been
transmitted from the mobile terminal 10 indicate the event related to the
30 characteristics type managed in the terminal specific detection item DB 45, the
detecting unit 42 detects the characteristics change of the mobile terminal 10 using
the characteristics change detecting DB 43 (S44) . When determining that the
event contents regarding which a notification has been transmitted from the mobi le
terminal 10 do not indicate the event related to the characteristics type managed in
20
the terminal specific detection item DB 45, the detecting unit 42 finishes
processing. In this regard, when the processing is finished, the detection server
40 may notify the control apparatus 30 that the processing is finished .
Alternatively, when determining that the event content s regarding which a
notification has been transmitted from the mobile terminal 10 do not indicate th5 e
event related to the characteristics type managed in the terminal specific detection
item DB 45, an inquiry whether or not the characteristics change related to the
event contents regarding which a notificat ion has been transmitted becomes a
monitoring target may be transmitted to the mobile terminal 10.
10 [0063]
Processing after the characteristics change is detected is the same as the
processing subsequent to step S23 in Fig. 7.
[0064]
As described above, by using the mobile communication system according
15 to the second embodiment of the present invention, the detection server 40 can
register in advance a characteristics change which needs to be detected. When,
for example, an automatic vending machine which is less frequent ly moved is used
as a mobile terminal, it is not necessary to detect a characteristics change related
to a move. In such a case, a move is not registered as a characteristics type which
20 needs to be detected. By so doing, it is possible to reduce a processing load
related to detection processing of the detection server 40.
[0065]
(Third Embodiment)
Next, a configurat ion example of a mobile communicat ion system
25 according to the third embodiment of the present invention will be descr ibed. A
control apparatus 30 and a processing node 20 have been described as physically
different apparatuses in the first and second embodiments . In this regard, a
function executed in the control apparatus 30 may be installed in a mobility
management entity 22 in the third embodiment .
30 [0066]
A configurat ion example of the mobile communicat ion system according to
the third embodiment of the present invent ion will be described with reference to
Fig. 12. Hereinafter, differences between Figs. 1 and 12 will be mainly described.
The mobile communication system in Fig. 12 has a radio base station 21, a
21
detection server 40 and a mobility management entity 60.
[0067]
Next, a configurat ion example of the mobi lity management ent i ty 60
according to the third embodiment of the present invention will be described with
reference to Fig. 13. The mobility management entity 60 has interfaces 61 and 625 ,
a control unit 63, a NW control policy DB 64, a notifying unit 65 and a NW
connection processing control unit 66.
[0068]
The interface 61 transmits and receives data to and from the detection
10 server 40. The interface 62 transmits and receives data to and from the mobili ty
management entity 22.
[0069]
The control unit 63 receives information related to a chara cteristics change
of a mobile terminal 10 output from the detection server 40, through the interface
15 61. Furthermore, the control unit 63 may output an event notice received from
the mobile terminal 10 through the interface 62, to the detection server 40 through
the interface 61. The control unit 63 extracts a NW control policy corresponding
to the received characteristics change using the NW control pol icy DB 64. The
NW control policy DB 64 is the same as the configurat ion in Fig. 5, and therefore
20 will not be described in detail .
[0070]
Furthermore, the control unit 63 performs processing of applying the NW
control policy extracted from the NW control policy DB 64, and sett ing the NW
control policy. Alternatively, the control unit 63 may transmit a notification of
25 the NW control policy extracted from the NW control policy DB 64, to the base
station 21 through the notifying unit 65 and the interface 62 .
[0071]
When a connection request from the mobile terminal 10 is executed, the
NW connection processing control unit 66 controls NW connection processing to
30 provide a state where communication can be executed between the mobi le terminal
10 and the radio base stat ion 21. The NW connect ion processing is general
processing in mobile communicat ion, and therefore will not be described in detail .
[0072]
Next, a flow of processing of setting a NW control policy according to the
22
third embodiment of the present invention will be described with reference to Fig.
14. Step S51 to step S53 in Fig. 14 are the same as step S21 to step S23 in Fig. 7,
and therefore wil l not be described in detail .
[0073]
Next, the mobility management ent ity 60 determines NW control pol ic5 y
contents corresponding to the characterist ics change regarding which a notification
has been transmitted from the detection server 40 (S54) . Next, the mobility
management entity 60 changes the current ly set NW control pol icy to the NW
control policy determined in step S54 (S55) .
10 [0074]
As described above, the mobility management entity 60 acc ording to the
third embodiment of the present invention includes a function of the control
apparatus 30 in Fig. 1. Consequently, an interface between the control apparatus
30 and the mobility management enti ty 22 in Fig. 1 is not necessary. Furthermore,
15 it is not necessary to transmit and receive data between the control apparatus 30
and the mobility management ent ity 22 in Fig. 7, so that i t is possible to reduce a
signal amount of the entire mobile communication system.
[0075]
(Fourth Embodiment )
20 Next, a configurat ion example of a mobile communicat ion system
according to the fourth embodiment of the present invention wil l be described with
reference to Fig. 15. The mobile communication system in Fig. 15 defines an API
between a control apparatus 30 and a detection server 40, and executes data
communicat ion between the control apparatus 30 and the detection server 40 .
25 The detection server 40 executes data processing using a function provided by the
API.
[0076]
A mobile communication business operator managing the mobi le
communicat ion system provides the API between the control apparatus 30 and the
30 detection server 40, so that the detection server 40 can be managed by a third party
other than the mobi le communication business operator and can be arran ged
outside a core network 50. Consequently, the third party can operate and manage
the detection server 40.
[0077]
23
(Fifth Embodiment )
Next, a configurat ion example of a mobile communicat ion system
according to the fifth embodiment of the present invent ion will be described with
reference to Fig. 16. An example will be described in the fifth embodiment where
a function executed in a detection server 40 is installed in a mobile terminal 705 .
The mobile communication system in Fig. 16 has a control appara tus 30, a base
station 21 and a mobi lity management ent i ty 22 . The mobile terminal 70
communicates with other mobile terminals and a server apparatus through the
mobile communicat ion system. The mobi le communication system in Fig. 16
10 differs from the mobi le communication system in Fig. 1 in that the detection server
40 is not provided.
[0078]
Next, a configurat ion example of the mobi le terminal 70 according to the
fifth embodiment of the present invention will be described with reference to Fig.
15 17. The mobile terminal 70 has an interface 71, a detecting unit 72, a
characteristics change detecting DB 73 and a not ifying unit 74 .
[0079]
The detecting unit 72 detects event information. As described above, the
event information may be information of an operat ion of a user who operates the
20 mobile terminal 70 or sensor information detected by the mobile terminal 70. The
detecting uni t 72 extracts a characteristics change corresponding to the detected
event information using the characteristics change det ecting DB 73. A
configuration of the characteristics change detecting DB 73 is the same as that in
Fig. 3, and therefore will not be described in detail .
25 [0080]
When extracting the characteristics change corresponding to the event
information detected by the detecting unit 72, the detecting unit 72 outputs the
extracted characterist ics change to the notifying unit 74 .
[0081]
30 The not ifying unit 74 outputs the characteristics change output from the
detecting uni t 72, to the control apparatus 30 through the interface 71.
[0082]
Next, a flow of processing of setting a NW control policy according to the
fifth embodiment of the present invention will be described with reference to Fig.
24
18. First, the mobile terminal 70 detects event information (S61) . Next, the
mobile terminal 70 detects a characteristics change corresponding to the detected
event contents (S62). Next, the mobile terminal 70 transmi ts a notification about
the detected characteristics change to the control apparatus 30 (63) . A terminal
identifier of the mobi le terminal 70 is also included in a message in which 5 a
notification about the characteristics change is transmitted from the mobile
terminal 70 to the control apparatus 30.
[0083]
Step S64 to step S66 are the same as step S24 to stop S26 in Fig. 7, and
10 therefore will not be described in detail .
[0084]
As described above, the mobile terminal 70 according to the fifth
embodiment of the present invention includes a function realized in the detect ion
server. Consequently, it is possible to skip data communication between the
15 mobile terminal 70 and the detection server, and reduce a signal amount of the
entire mobile communication system.
[0085]
Although the present invention has been described as a hardware
configuration in the above embodiments, the present invention is not limited to
20 these embodiments. The present invention can also be realized by execut ing a
computer program which causes a CPU (Central Processing Uni t ) to perform the
processing of the detection server and the control apparatus in Fig. 7 and the
processing disclosed in Fig. 11. ).
[0086]
25 In the above example, the program can be supplied to the computer by
being stored using various types of non-transitory computer readable media. The
non-transitory computer readable media include various types of tangible storage
media. The non-transitory computer readable media include, for example,
magnetic recording media (e.g. flexible disks, magnetic tapes and hard disk drives),
30 magnetooptical recording media (e.g. magnetooptical disks), CD-ROMs (Read
Only Memory), CD-Rs, CD-R/Ws, and semiconductor memories (e.g. mask ROMs,
PROMs (Programmable ROM), EPROMs (Erasable PROM), flash ROMs and
RAMs (Random Access Memory)). Furthermore, the program may be supplied to
the computer using various types of transi tory computer readable media. The
25
transitory computer readable media include, for example, electric signals, optical
signals and electromagnet ic waves . The transitory computer readable media can
supply the program to the computer using wired communication channels such as
electric wires and opt ical fibers or wireless communication channels .
[00875 ]
In addition, the present invention is not l imited to the above embodiments,
and can be adequately changed as long as the change does not deviate from the
spirit of the invention.
[0088]
10 Although the present invention has been described with reference to the
