Therefore, the management device 30 can accurately specify the position of the mobile communication terminal 20 without being affected by the change of management information in the mobile network 40 by the communication carrier.

(Embodiment 2)
Subsequently, a configuration example of the communication system according to the second exemplary embodiment of the present invention will be described with reference to FIG. The communication system of FIG. 2 shows a network configuration defined in 3GPP. 2 includes a UE (User Equipment) 50, an eNB (evolved NodeB) 60, an SGW (Serving Gateway) 70, a PGW (PDN-Gateway) 80, an MME (Mobility Management Entity) 90, a PCRF (Policy and Charging Rules). Function) 100, HSS (Home Subscriber Server) 110, and management device 30.

UE 50 is a general term for mobile communication terminals in 3GPP. The UE 50 corresponds to the mobile communication terminal 20 in FIG. The eNB 60 is a base station that can execute LTE (Long Term Term Evolution) as a communication method. The SGW 70 and the PGW 80 are devices that relay user data related to the UE 50. The MME 90 performs call processing control related to the UE 50. The PCRF 100 performs charging control or path control according to a network policy. The HSS 110 holds subscriber data of the UE 50. SGW70, PGW80, MME90, PCRF100, and HSS110 are equivalent to the core network apparatus 10 of FIG. Moreover, eNB60, SGW70, PGW80, MME90, PCRF100, and HSS110 comprise the mobile network 40 of FIG.

The GPS information generation unit 52 generates GPS information. The GPS information generation part 52 may generate | occur | produce GPS information regularly and may produce | generate GPS information according to the instruction | indication of the user who operates UE50. The GPS information may be information indicating latitude and longitude, or information indicating an address generated using information indicating latitude and longitude.

The signal generation unit 53 generates a signal to be transmitted to the mobile network 40. For example, the signal generation unit 53 may generate a control message or user data to be transmitted to the mobile network 40. The control message may be referred to as C-Plane data, and the user data may be referred to as U-Plane (User Plane) data.

The signal generator 53 generates a control message in which the GPS information generated by the GPS information generator 52 is set. That is, the signal generation unit 53 can transmit the GPS information as a control message to the mobile network 40 instead of transmitting the GPS information as application data or user data.

Further, after the UE 50 is connected to the mobile network 40, the signal generation unit 53 may transmit the GPS information generated by the GPS information generation unit 52 to the management device 30 as user data.

The communication unit 51 transmits the signal generated by the signal generation unit 53 to the eNB 60. The communication unit 51 may transmit a signal to the eNB 60 by wireless communication using LTE, for example.

Subsequently, a configuration example of the MME 90 according to the second exemplary embodiment of the present invention will be described with reference to FIG. The MME 90 includes a communication unit 91 and a signal generation unit 92.

The communication unit (transmission / reception unit) 91 receives a control message transmitted from the UE 50 via the eNB 60. Further, the communication unit 91 transmits the control message generated by the signal generation unit 92 to the surrounding node devices including the management device 30.

The signal generator 92 extracts the GPS information set in the control message transmitted from the UE 50. Further, the signal generation unit 92 generates a control message in which the extracted GPS information is set. The signal generation unit 92 transmits the control message in which the GPS information is set, for example, to the HSS 110 or the management device 30 via the communication unit 91.

In this figure, the configuration example of the MME 90 has been described, but the SGW 70, the PGW 80, and the PCRF 100 may have the same functions as the MME 90. That is, the SGW 70, the PGW 80, and the PCRF 100 can transmit a control message in which GPS information is set to the HSS 110 or the management apparatus 30.

Subsequently, a flow of processing for determining whether or not to permit connection of the UE 50 to the mobile network 40 according to the second embodiment of the present invention will be described with reference to FIG. In this figure, the flow of determination processing will be described assuming that the HSS 110 has the function of the management device 30. In addition, in this figure, a flow of processing for determining whether or not to permit connection of the UE 50 to the mobile network 40 in the Attach processing executed when the UE 50 is turned on or the like will be described.

First, the UE 50 transmits a NAS: S1AP-InitialUEMessage / EMM-Attach Req / ESM-PdnConnectReq message to the MME 90 (S11). NAS: S1AP-InitialUEMessage / EMM-Attach Req / ESM-PdnConnectReq message indicates that S1AP-InitialUEMessage contains EMM (Evolved packet system Mobility Management) message and ESM (Evolved packet system Session Management) message Yes. For example, the UE 50 sets GPS information in the ESM-PdnConnectReq message. The MME 90 holds the GPS information set in the ESM-PdnConnectReq message transmitted in step S11.

Next, UE50, MME90, and HSS110 perform the authentication process regarding UE50 (S12). Next, the MME 90 transmits an Update Location Request message to the HSS 110 (S13). Next, the HSS 110 transmits an Update 応答 Location Answer message in which subscriber information of the UE 50 is set as a response signal to the MME 90 (S14).

Next, the MME 90 transmits a Notify request message in which the GPS information of the UE 50 received in step S11 is set to the HSS 110 (S15). Next, HSS110 determines whether the position of UE50 specified from GPS information is in the area where communication is permitted previously (S16).

Next, the HSS 110 transmits a NotifyAnwser message in which a determination result regarding whether or not to permit the connection of the UE 50 is set to the MME 90 (S17). The Notify Request message and Notify Answer message are messages used in the S6a interface defined between the MME 90 and the HSS 110. When the MME 90 receives a determination result indicating that the connection is not permitted, the MME 90 performs a process of rejecting the Attach of the UE 50, and when receiving a determination result that permits the connection, the MME 90 continues the Attach process of the UE 50 (S18). In step S18, the MME 90 may notify the UE 50 of information related to whether or not the Attach connection is possible. When the HSS 110 determines that the connection is not permitted, the HSS 110 may set a value indicating the reason for determining that the connection is not permitted in the NotifyNotAnswer message.

Subsequently, the processing flow for determining whether or not to permit connection of the UE 50 to the mobile network 40 according to the modification of the second embodiment of the present invention using FIG. 6 is different from the processing flow of FIG. Processing will be described. In this figure, the HSS 110 does not have a function executed in the management device 30, and the HSS 110 and the management device 30 are described as different devices.

Steps S21 to S24 are the same as steps S11 to S14 in FIG.

Next, the MME 90 transmits a Notify request message to the HSS 110 (S25). In step S25, the MME 90 does not set the GPS information received in step S21 in the Notify Request message. For example, the MME 90 transmits a Notify request message to the HSS 110 in order to notify the HSS 110 of the Cell ID indicating the cell where the UE 50 is located (S25). Next, the HSS 110 transmits a Notify Answer message to the MME 90 as a response message to the Notify Request message (S26).

Next, the MME 90 transmits a location information notification message in which the GPS information of the UE 50 received in step S21 is set to the management device 30 (S27). The location information notification message may be, for example, a message defined by the Diameter protocol.

Next, the management device 30 determines whether or not the position of the UE 50 specified from the GPS information is an area where communication is permitted in advance (S28).

Next, the management apparatus 30 transmits a location information notification response message in which a determination result regarding whether or not to permit connection of the UE 50 is set to the MME 90 (S29). The location information notification response message may be a message defined by the Diameter protocol in the same manner as the location information notification message. When the MME 90 receives a determination result indicating that the connection is not permitted, the MME 90 executes a process of rejecting the Attach of the UE 50, and when receiving a determination result that permits the connection, the MME 90 continues the Attach process of the UE 50 (S30). In step S30, the MME 90 may notify the UE 50 of information regarding whether or not the Attach connection is possible. When determining that the connection is not permitted, the management device 30 may set a value indicating the reason for determining that the connection is not permitted in the position information notification response message.

Subsequently, with reference to FIG. 7, the processing flow for determining whether to permit the connection of the UE 50 to the mobile network 40 according to the second modification of the second embodiment of the present invention is shown in FIG. 5 and FIG. 6. A process different from the flow will be described.

Steps S31 to S36 are the same as steps S21 to S26 in FIG. However, here, the MME 90 performs processing with the PCRF 100 instead of the HSS 110. Next, the MME 90 sends a GTP (General packet radio system tunneling protocol) v2 Create Session Request message with GPS information set to the SGW 70, and the SGW 70 sends a GTPv2 Create Session Request message with the GPS information set to the PGW 80. (S37). A session between the SGW 70 and the PGW 80 is established by transmitting and receiving a GTPv2ＷCreate Session Request message between the MME 90 and the PGW 80.

Next, the PGW 80 transmits a Credit Control Request message in which the GPS information received in Step S37 is set to the PCRF 100 (S38).

Next, the PCRF 100 transmits a location information notification message in which the GPS information of the UE 50 received in step S38 is set to the management device 30 (S39). The location information notification message may be, for example, a message defined by the Diameter protocol.

Next, the management device 30 determines whether or not the position of the UE 50 specified from the GPS information is within an area where communication is permitted in advance (S40).

Next, the management device 30 transmits to the PCRF 100 a location information notification response message in which a determination result regarding whether or not to permit connection of the UE 50 is set (S41). The location information notification response message may be a message defined by the Diameter protocol in the same manner as the location information notification message. When determining that the connection is not permitted, the management device 30 may set a value indicating the reason for determining that the connection is not permitted in the position information notification response message.

Next, the PCRF 100 transmits a Credit Control Answer message to the PGW 80 as a response to the Credit Control Request message in Step S38 (S42). Here, if the value indicating the reason for determining that the connection of the UE 50 is not permitted in step S41 is set, the PCRF 100 sets the value indicating the reason for determining that the connection of the UE 50 is not permitted even in the Credit Control Answer message. It may be set.

Next, the PGW 80 transmits a GTPv2 Create Session Response message to the MME 90 as a response to the GTPv2 Create Session Request message in Step S37 (S43). Here, if the value indicating the reason for determining that the connection of the UE 50 is not permitted in step S42 is set, the value indicating the reason for determining that the connection of the UE 50 is not permitted even in the GTPv2 Create Session Response message. May be set. Next, the MME 90 may notify the UE 50 of information related to whether the Attach connection of the UE 50 is possible (S44).

Next, with reference to FIG. 8, FIG. 5, FIG. 6, and FIG. 5, FIG. 5, FIG. 6, and FIG. A process different from the process flow of 7 will be described. Steps S51 to S57 are the same as steps S31 to S37 in FIG.

Subsequently, the PGW 80 transmits a Credit Control Request message to the PCRF 100 (S58). Here, the PGW 80 may not set the GPS information of the UE 50 in the CreditCrControl Request message as in step S38 of FIG. Next, the PCRF 100 transmits a Credit Control Answer message to the PGW 80 as a response to the Credit Control Request message (S59).

Next, the PGW 80 transmits a location information notification message in which the GPS information of the UE 50 received in step S57 is set to the management device 30 (S60). The location information notification message may be, for example, a message defined by the Diameter protocol.

Next, the management device 30 determines whether or not the position of the UE 50 specified from the GPS information is an area where communication is permitted in advance (S61).

Next, the management device 30 transmits a location information notification response message in which a determination result regarding whether or not to permit connection of the UE 50 is set to the PGW 80 (S62). The location information notification response message may be a message defined by the Diameter protocol in the same manner as the location information notification message. When determining that the connection is not permitted, the management device 30 may set a value indicating the reason for determining that the connection is not permitted in the position information notification response message.

Next, the PGW 80 transmits a GTPv2 Create Session Response message to the MME 90 as a response to the GTPv2 Create Session Request message in Step S57 (S63). Here, if the value indicating the reason for determining that the connection of the UE 50 is not permitted in step S62 is set, the value indicating the reason for determining that the connection of the UE 50 is not permitted in the GTPv2 Create Session Response message. May be set. Next, the MME 90 may notify the UE 50 of information related to whether the Attach connection of the UE 50 is possible (S64).

As described above, by using the communication system according to the second embodiment of the present invention, the management apparatus 30 allows the UE 50 to connect to the mobile network 40 using GPS information in a network defined by 3GPP. It is possible to execute a process of determining whether or not

Further, the following service can be realized by using the communication system according to the second embodiment of the present invention. For example, by using the communication system according to the second embodiment of the present invention, a service provider or the like prohibits the use of a mobile phone or a smartphone in a specific place such as a hospital specified by GPS information. be able to. By using GPS information, a service provider or the like can set an area where use of a mobile phone or the like is prohibited in detail.

(Embodiment 3)
Next, a flow of PDP (Packet Data Protocol) release processing according to the third exemplary embodiment of the present invention will be described with reference to FIG. PDP (may also be referred to as PDP connection, PDP context, etc.) is logical path (route) information for transferring packet data set between UE 50 and PGW 80. The PDP is set for each call type or for each service. For example, a plurality of PDPs such as a PDP for packet data and a PDP for voice call may be set between the UE 50 and the PGW 80.

In this figure, the flow of the PDP release process will be described assuming that the HSS 110 has the function of the management device 30. Moreover, in this figure, it is set as the state by which the connection determination process of UE50 is performed and the connection of UE50 is permitted by the procedure of FIG.

First, the UE 50 transmits GPS information as U-Plane data to the HSS 110 (S71). UE50 may transmit GPS information to HSS110 regularly, and may transmit GPS information to HSS110, when moving a predetermined distance.

Subsequently, the HSS 110 determines whether or not to allow the UE 50 to communicate via the mobile network 40 (S72). Here, a process for determining whether communication is possible for the UE 50 in the HSS 110 will be described.

The HSS 110 determines whether or not the position of the UE 50 specified from the GPS information received in step S71 is within an area where communication is permitted in advance. Here, the HSS 110 may determine to reject the communication of the UE 50 when the UE 50 determines that the UE 50 does not exist in an area where communication is permitted in advance. Alternatively, when the UE 50 determines that the UE 50 does not exist in an area where communication is permitted in advance, the HSS 110 may reject or permit communication according to the call type.

For example, when the UE 50 moves out of an area where communication is permitted in advance, the HSS 110 may determine that voice communication is permitted but packet data transmission / reception is not permitted.

When the HSS 110 determines to reject the communication in step S72, the HSS 110 transmits a PDP release request message to the MME 90 in order to instruct the release of the PDP associated with the rejected communication (S73). The HSS 110 may instruct release of all PDPs set between the UE 50 and the PGW 80 in the PDP release request message, for example, instruct to release only the PDP associated with transmission / reception of packet data. May be. Here, the HSS 110 may use an Insert Subscriber Data Request message used in the S6a interface as the PDP release request message.

Next, the MME 90 transmits a PDP release response message to the HSS 110 as a response to the PDP release request message in step S73 (S74). The MME 90 may use the Insert Subscriber Data Response message used in the S6a interface as the PDP release response message.

Next, the MME 90 activates a process for releasing the PDP instructed to be released in step S73 (S75).

Subsequently, the flow of the PDP release process according to the third embodiment of the present invention will be described with reference to FIG.

First, the UE 50 transmits a NAS: S1AP-UplinkNasTransport message in which GPS information is set to the MME 90 (S81). The GPS information may be set in, for example, an ESM message included in the S1AP-UplinkNasTransport message.

Next, the MME 90 transmits a Notify request message in which GPS information is set to the HSS 110 (S82). The MME 90 may set QCI (QoS Class Identifier) information indicating the call type set in the UE 50 in the Notify Request message.

Subsequently, the HSS 110 determines whether or not to allow the UE 50 to communicate via the mobile network 40 (S83). Since the determination process in step S83 is the same as step S72 in FIG. 9, detailed description thereof is omitted.

Next, when the HSS 110 determines to reject the communication in step S83, the HSS 110 transmits a Notify Answer message indicating that the PDP associated with the rejected communication is instructed to be released to the MME 90 (S84).

Next, the MME 90 activates a process for releasing the PDP instructed to be released in step S84 (S85).

First, the MME 90 transmits a NAS: S1AP-DownlinkNasTransport message to the UE 50 in order to request transmission of GPS information (S91). For example, information indicating that transmission of GPS information is requested may be set in an ESM message included in an S1AP-DownlinkNasTransport message. The MME 90 may transmit a NAS: S1AP-DownlinkNasTransport message to the UE 50 periodically. Or HSS110 may notify the timing which transmits NAS: S1AP-DownlinkNasTransport message to MME90, and MME90 may transmit a NAS: S1AP-DownlinkNasTransport message according to the timing notified from HSS110.

Further, when the HSS 110 notifies the MME 90 of the timing for transmitting the NAS: S1AP-DownlinkNasTransport message, the NetLoc (Network Provided Location Information Information for IMS) function may be used. The NetLoc function is a function defined in 3GPP, and defines a procedure for acquiring location information held by the UE under the initiative of the network side. Further, in the NetLoc function, information regarding a cell in which the UE is located in the network can be generally acquired. However, the network may acquire GPS information of the UE here.

Steps S92 to S96 are the same as steps S81 to S85 in FIG.

First, the MME 90 activates an LCS (Location Service) function (S101). The MME 90 acquires GPS information from the UE 50 by activating the LCS function (S102). Steps S103 to S106 are the same as steps S82 to S85 in FIG.

9 to 12, the HSS 110 has been described as having the function of the management apparatus 30. However, the HSS 110 does not have a function executed by the management apparatus 30, and the HSS 110 and the management apparatus 30 are different apparatuses. There may be. In this case, the PDP release request message and the PDP release request response message in FIG. 9 may be replaced with messages defined by the Diameter protocol. A message defined by the Diameter protocol is transmitted / received between the MME 90 and the management apparatus 30.
