  The present invention relates to an information management apparatus.

  2. Description of the Related Art Conventionally, communication terminals that provide a wireless communication network and can be used by the wireless communication network are provided. The communication terminal provided for each wireless communication network is a so-called SIM lock in which only a USIM (Universal Subscriber Identity Module) used for connection to a specific wireless communication network can be used. It was a terminal. On the other hand, in recent years, so-called SIM lock-free terminals that can use SIMs used for connection to different wireless communication networks are increasing (for example, see Patent Document 1). In this case, by changing the SIM attached to the communication terminal, it becomes possible to connect to different wireless communication networks while using the same communication terminal.

Japanese Unexamined Patent Publication No. 2016-32283

  Here, in order to start communication using a specific wireless communication network by the SIM lock-free terminal, it is necessary to perform initial setting according to the service used in the communication terminal such as APN (Access Point Name) setting. However, the SIM lock-free terminal side does not know what services are available on the connection destination communication network. Therefore, it is necessary to provide the information from the information management device on the wireless communication network side to the communication terminal.

  The present invention has been made in view of the above, and is capable of notifying a SIM lock-free terminal that starts communication by connecting to a wireless communication network, with information related to services available on the wireless communication network. It is an object to provide a simple information management device.

  In order to achieve the above object, an information management apparatus according to an embodiment of the present invention is an information management apparatus included in a communication system that controls a wireless communication network, and is a communication terminal related to a communication carrier of the wireless communication network. A terminal information storage unit for storing information for specifying the model of the terminal, terminal identification information including information for identifying the communication terminal and information for identifying the model of the communication terminal, and information for identifying the user of the communication terminal A registration request receiving unit that receives a registration request to the wireless communication network from a communication terminal including the user identification information, and the terminal identification information included in the registration request received by the registration request receiving unit Information for specifying the model of the communication terminal is extracted, information for specifying the extracted model of the communication terminal, and information stored in the terminal information storage unit A terminal determination unit that determines whether the communication terminal that transmitted the registration request corresponds to a communication terminal that needs to notify a service provided by the wireless communication network, and a determination by the terminal determination unit As a result, a message delivery unit that delivers a message notifying the service provided by the wireless communication network to the communication terminal determined to be notified of the service provided by the wireless communication network. It is characterized by that.

  According to the above information management device, in the terminal determination unit, information specifying the model of the communication terminal extracted from the terminal identification information included in the registration request, and communication of the wireless communication network stored in the terminal information storage unit Whether or not the communication terminal to which the information management device has transmitted a registration request based on the information specifying the model of the communication terminal related to the carrier falls under the category of a communication terminal that needs to notify the service provided by the wireless communication network Judgment is made. As a result, the communication terminal that needs to notify the service provided by the wireless communication network is notified by distributing a message from the message distribution unit of the information management apparatus. Therefore, for example, when the communication terminal that transmitted the registration request is not a communication terminal related to a communication carrier of the wireless communication network, such as a SIM lock-free terminal, wireless communication is performed based on the determination result by the terminal determination unit. It is possible to notify information related to services available on the network.

  Here, the terminal information storage unit stores information for specifying a specification for each model of the communication terminal in association with information for specifying a model of a communication terminal related to a communication carrier of the wireless communication network, The terminal determination unit is a communication terminal related to a communication carrier of the wireless communication network in which information specifying the model of the communication terminal extracted from the communication terminal that transmitted the registration request is stored in the terminal information storage unit When the information matches the information specifying the model of the communication terminal, the communication terminal that transmitted the registration request refers to the information specifying the specification of each model of the communication terminal and notifies the service provided by the wireless communication network. It can be set as the aspect which determines whether it corresponds to the communication terminal which needs to be performed.

  As described above, in addition to the information specifying the model of the communication terminal, information specifying the specification for each model is stored, and the communication terminal needs to notify the service provided by the wireless communication network in the terminal determination unit For example, even if it is a model of a communication terminal related to a communication carrier of a wireless communication network, a service provided by the wireless communication network is notified. When there is a communication terminal that needs to be used, it is possible to select an appropriate notification destination using the specification information, and to notify information related to services available on the wireless communication network Become.

  The terminal information storage unit stores terminal identification information related to a communication terminal that has received a registration request in the past in association with user identification information included in the registration request, and the terminal determination unit receives the registration request. When the terminal identification information included in the registration request received at the terminal is stored in the terminal information storage unit in association with the user identification information as information indicating that the registration request has been received in the past. It can be set as a mode in which it is determined not to correspond to a communication terminal that needs to notify a service provided by the wireless communication network.

  As described above, in the information management device, the terminal identification information included in the registration request received by the registration request receiving unit is included in the terminal identification information of the communication terminal that has previously received the registration request stored in the terminal information storage unit In such a case, the same message is again notified to the communication terminal that has received the registration request in the past by determining that the service does not correspond to the communication terminal that needs to notify the service provided by the wireless communication network. Can be prevented. Therefore, it is possible to notify information related to services available on the wireless communication network while preventing an increase in communication volume.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic configuration diagram of a communication system 1 including an information management apparatus according to an embodiment of the present invention. The communication system 1 is a system provided by a telecommunications carrier that provides a wireless communication network, and provides data communication, voice communication, and the like to a communication terminal connected to the wireless communication network controlled by the communication system 1. It is. The communication system 1 includes an HSS (Home Subscriber Server) 10, an exchange 20, and an SMS distribution device 30 corresponding to the information management device according to the present embodiment. The communication terminal 40 realized by a smartphone, a tablet terminal, or the like can perform communication using a wireless communication network provided by the communication system 1 by connecting to the communication system 1.

  The HSS 10 is also referred to as a subscriber information management device, and is a server that performs authentication processing for the communication terminal 40 to perform communication using a wireless communication network, management of area information of the communication terminal, and the like. In the present embodiment, when there is a communication terminal 40 that is about to be newly located in the wireless communication network, the HSS 10 notifies the communication terminal 40 of services that can be used in the wireless communication network. This point will be described later.

  The exchange 20 is a device that relays a signal from the communication terminal 40 when the communication terminal 40 performs communication using a wireless communication network. As the exchange 20, different devices are used depending on the type of communication standard of the wireless communication network. For example, in the case of LTE (Long Term Evolution), MME (Mobility Management Entity) corresponds to the exchange. In 3G (3rd Generation), xGSN (serving / gateway General packet radio service Support Node) corresponds to an exchange. In the case of voice communication, ASN (Application Serving Node) corresponds to an exchange. As described above, as the exchange 20 that relays the signal from the communication terminal 40, an apparatus corresponding to the standard of the wireless communication network is used.

  The SMS distribution device 30 has a function of distributing a text message (SMS: Short Message Service) to the communication terminal 40. The SMS delivered to the communication terminal 40 via the SMS delivery device 30 includes a message exchanged between the communication terminals. In this embodiment, communication is performed from the wireless communication network side based on an instruction from the HSS 10. The SMS for network connection distributed to the terminal 40 will be described. The SMS transmitted from the SMS distribution device 30 is transmitted to the communication terminal 40 via an IWG (InterWork Gateway: not shown) corresponding to an SMS exchange.

  The communication terminal 40 is a so-called SIM lock-free terminal, and is attached to the USIM by attaching a USIM (Universal Subscriber Identity Module) in which information relating to connection to a telephone number and a wireless communication network is described. It is a terminal that enables communication using the described wireless communication network. In the present embodiment, a process when the communication terminal 40 attached with a USIM for connecting to a wireless communication network provided by the communication system 1 connects to the communication system 1 and starts communication will be described.

  Next, the HSS 10 that is the information management apparatus according to the present embodiment will be described. As shown in FIG. 1, the HSS 10 includes a location registration request reception unit 11 (registration request reception unit), a location registration processing unit 12, an SMS distribution necessity determination unit 13 (terminal determination unit), and an SMS distribution processing unit 14 (message distribution). Part) and the terminal information storage part 15 are comprised.

  In addition, physically, as shown in FIG. 2, the HSS 10 physically includes a CPU 101, a RAM 102 and a ROM 103 that are main storage devices, a communication module 104 that is a data transmission / reception device, a hard disk, a flash memory, and the like. The computer system includes an input device 106 exemplified by a touch panel and a keyboard as input devices, an output device 107 such as a display, and the like. In the HSS 10, by reading predetermined computer software onto hardware such as the CPU 101 and the RAM 102 shown in FIG. 2, the communication module 104, the input device 106, and the output device 107 are operated under the control of the CPU 101, and the RAM 102 In addition, by reading and writing data in the auxiliary storage device 105, a series of functions in each device is realized.

  Returning to FIG. 1, the location registration request receiving unit 11 of the HSS 10 has a function of receiving a location registration request from the communication terminal 40. The location registration request is a process necessary when the communication terminal 40 uses the wireless communication network provided by connecting to the communication system 1 and is also called an attach request. This location registration request corresponds to a registration request for the communication terminal 40 to the wireless communication network controlled by the communication system 1. The communication terminal 40 starts processing for using the wireless communication network provided by the communication system 1 based on the information described in the USIM when the power is turned on with the USIM attached. At this time, the communication terminal 40 used by a specific user requests the HSS 10 to register terminal information (location registration). The location registration request transmitted from the communication terminal 40 to the HSS 10 includes terminal identification information that is information for identifying a terminal and user identification information that is information for identifying a user of the terminal. In the present embodiment, the “user” refers to a person who uses a wireless communication network specified by information described in one USIM. That is, one USIM corresponds to one user.

  For example, IMEI (International Mobile Equipment Identifier) is used as the terminal identification information. IMEI is an international mobile device identification number, for example, a 15-digit number assigned to each terminal. The 15-digit number of IMEI includes TAC (Type Allocation Code) which is information for specifying the terminal model. TAC is an 8-digit number, for example, and is a number set for each model. In addition, even if the terminals are manufactured in the same model, terminals whose internal software settings and the like are changed due to different providers are usually terminals of different models. Thus, the terminal identification information includes model specifying information for specifying the model.

  Also, as the user identification information, unique information described in the USIM and set for each USIM can be used. For example, IMSI (International Mobile Subscriber Identity), telephone number, and MSN (Mobile Subscriber number) are used as such user identification information. The user specifying information is information not related to the communication terminal (device).

  The location registration processing unit 12 performs processing related to location registration of the communication terminal 40 based on the location registration request from the communication terminal 40 received by the location registration request receiving unit 11. The processing performed in the location registration processing unit 12 is the same as the processing conventionally performed in the HSS.

  The SMS delivery necessity determination unit 13 is configured to connect the communication terminal 40 to the communication terminal 40 based on information included in the location registration request from the communication terminal 40 and information stored in the terminal information storage unit 15. It is determined whether or not to deliver the SMS. Here, the SMS for network connection is a message for notifying a service provided by the wireless communication network. The network connection SMS needs to be distributed to the communication terminal 40 when the following conditions are satisfied. That is, the provider of the communication terminal 40 is different from the communication carrier that operates the wireless communication network provided by the communication system 1.

  In general, in the case of a communication terminal related to a communication carrier operating a wireless communication network, information for facilitating the use of a communication service using the wireless communication network, for example, an APN (Access Point Name) setting Information relating to the above is stored in advance in the communication terminal. Therefore, when a USIM for connection to the wireless communication network is attached to a communication terminal related to a communication carrier that operates the wireless communication network, wireless communication is performed by combining information stored in advance in the communication terminal. Processing relating to connection to the communication network can be performed smoothly.

  On the other hand, for example, the communication source of the wireless communication network is provided by a provider such as a communication terminal provided by another communication carrier or a communication terminal that is not limited to use by a specific communication carrier. In the case of a communication terminal different from the service provider, information related to the wireless communication network is not stored in the communication terminal, and therefore processing related to connection to the wireless communication network is performed based only on the information described in the USIM. However, there are cases where it is not possible to sufficiently grasp various services used via the wireless communication network on the terminal side only by the information described in the USIM. In this case, various settings for using the various services are performed. I can't. Therefore, it is necessary to notify the service provided by the wireless communication network from the wireless communication network side, that is, the communication system 1 side to the communication terminal by SMS or the like. However, if the above information is notified to all the communication terminals that have transmitted the location registration request, there is a possibility that communication load and unnecessary signal transmission / reception increase. Therefore, the HSS 10 uses the TAC, which is information specifying the model included in the IMEI, to determine whether or not the communication terminal notifies information related to a service provided by the wireless communication network.

  In some cases, a communication terminal specified by the same TAC as a communication terminal related to a communication carrier that operates a wireless communication network is provided by another person such as another communication carrier. In this case, it is not possible to clearly determine whether the TAC alone corresponds to a communication terminal related to a communication carrier operating a wireless communication network. Therefore, it is desired to determine whether or not the communication terminal that notifies the service provided by the wireless communication network by SMS or the like is based on other information provided from the communication terminal. However, even if other information provided from the communication terminal is referred to, it may not be possible to determine whether the service provided by the wireless communication network corresponds to the communication terminal that notifies the service by SMS or the like. In this case, for the sake of safety, it is conceivable that a uniform SMS is distributed to a communication terminal corresponding to the TAC (even if the communication carrier of the wireless communication network provides). In the case where there is an exceptional case as described above, the SMS distribution necessity determination unit 13 of the HSS 10 considers those circumstances and determines whether or not to notify the service provided by the wireless communication network. Has a function to judge.

  As described above, in the communication system 1 according to the present embodiment, for each communication terminal that has received a location registration request, the SMS distribution necessity determination unit 13 of the HSS 10 notifies whether or not the service provided by the wireless communication network is notified. Determine whether. The SMS delivery necessity determination unit 13 makes a determination based on information provided from the communication terminal 40 together with the location registration request and information stored in the terminal information storage unit 15 of the HSS 10. Details will be described later.

  The SMS distribution processing unit 14 distributes the SMS as a message related to the notification to the communication terminal determined by the SMS distribution necessity determination unit 13 to be notified of the service provided by the wireless communication network. It has a function to perform such processing. Specifically, information specifying the communication terminal 40 (information specifying the destination of the SMS) and information to be transmitted to the communication terminal 40 (information to be described as the text of the SMS) to the SMS distribution device 30. ) And requesting SMS delivery to the communication terminal 40.

  The terminal information storage unit 15 stores information on communication terminals registered as a result of the communication terminal location registration process normally performed by the HSS 10. Further, the terminal information storage unit 15 stores information for determining whether or not to notify the communication terminal 40 about the service provided by the wireless communication network in the SMS distribution necessity determination unit 13.

  Examples of information stored in the terminal information storage unit 15 are shown in FIGS. FIG. 3 shows a table in which IMEI and telephone numbers are associated with each user. In FIG. 3, for each of the users U01 to U04, a telephone number and IMEI are stored in association with each other. IMEI is originally different information for each communication terminal, but for simplicity, all are shown as “XXX...” In FIG. The information shown in FIG. 3 is information corresponding to a user profile for each user (USIM), and when a location registration process is performed, a user profile is created for each user (USIM). Further, when the location registration is performed again with the communication terminal used by the user changed, the IMEI (terminal identification information) in the user profile corresponding to the user is rewritten. Therefore, the information shown in FIG. 3 is information indicating the terminal identification information of the latest communication terminal associated with the user identification information (here, the telephone number) in the HSS 10. Therefore, when a user performs location registration by inserting a USIM into a different communication terminal, the location registration request transmitted from the communication terminal includes information on a combination different from the combination of IMEI and telephone number in FIG. Is included.

  FIG. 4 is a record in which a part of the profile information shown in FIG. 3 is accumulated and a history of notifications to the communication terminal is recorded. In FIG. 4, in addition to the combination of IMEI and telephone number, when SMS delivery is performed, a flag indicating that SMS delivery has been performed is given. Among the information shown in FIG. 4, the phone number and IMEI are stored in each user by performing location registration processing based on a request from the communication terminal in the location registration processing unit 12, that is, from the user profile. Information to be extracted. However, when location registration is performed again with the communication terminal used by the user changed, IMEI (terminal identification information) is rewritten in the user profile shown in FIG. 3, but the profile information shown in FIG. 4 is shown in FIG. When the user profile is rewritten, a new telephone number and IMEI combination is added. That is, the information shown in FIG. 4 can be said to be information corresponding to a history of a location registration request transmitted from the communication terminal in the past. The information shown in FIG. 4 is information that is transmitted and accumulated every time the communication terminal with the USIM is turned on. Therefore, when a communication terminal having a different specific user (corresponding USIM) is used, a location registration process is performed in a combination of the user and a different communication terminal, and the information shown in FIG. 4 is updated. In the example illustrated in FIG. 4, the user U01 first uses the communication terminal specified by IMEI “AAA ...”, but then the communication terminal to which the USIM is attached is specified by IMEI “BBB ...”. The case where the location registration process is performed again after changing to the above is described. In this case, as shown in FIG. 4, information related to the user U01 (a combination of a telephone number and IMEI) is accumulated. In this way, each time the communication terminal to which the USIM is attached is changed, user information corresponding to the USIM is accumulated.

  In the table shown in FIG. 4, information indicating whether or not a communication terminal has been notified is recorded in association with the “distribution status”. In FIG. 4, the distribution status is not displayed for the communication terminal specified by IMEI “AAA. This indicates that the communication terminal specified by IMEI “AAA...” Is a communication terminal related to a communication carrier operating the wireless communication network and is a communication terminal that does not require notification. On the other hand, the communication terminal identified by IMEI “BBB...” Has a distribution status of “distributed”, indicating that notification is being made (SMS is distributed). In this manner, information related to whether notification has been performed is associated with the combination of the telephone number and IMEI and recorded.

  The SMS delivery necessity determination unit 13 refers to the information (registered user profile) shown in FIG. 3 to determine whether to deliver the SMS to the communication terminal based on whether the IMEI is registered. However, as shown in FIG. 4, information indicating whether the communication terminal specified by the telephone number and IMEI has been notified (whether SMS distribution has been performed) may be additionally provided.

  As illustrated in FIG. 4, when information indicating whether or not a notification related to a service provided by a wireless communication network is performed is stored in the terminal information storage unit 15 in association with a telephone number and IMEI, the same user When a location registration request is transmitted many times using the same communication terminal, it is possible to prevent the communication terminal from repeatedly providing notification about the service provided by the wireless communication network. Since the information shown in FIG. 4 is the information accumulated as described above, when location registration has been performed in the past by a combination of a specific user (phone number) and a communication terminal (IMEI). The combination should be accumulated as shown in FIG. However, as shown in FIG. 4, if information indicating whether or not a notification related to a service provided by the wireless communication network is stored in association with each other, a notification regarding the service provided by the wireless communication network is more appropriate. And the number of SMS distributions for notification can be reduced.

  FIG. 5 shows a table in which the specifications of the model are associated with each model of the communication terminal. In FIG. 5, TAC is used as information for specifying the model of the communication terminal. And, for TAC, manufacturer (manufacturer), contract (information specifying a wireless communication network to which the communication terminal can be connected), and various specifications related to the communication terminal (for example, OS (Operating System), steering, etc.) ) Are associated. Note that the terminal information storage unit 15 stores only information related to a communication terminal related to a telecommunications carrier operating a wireless communication network. That is, information related to a communication terminal different from a communication terminal related to a communication carrier operating a wireless communication network is not included in the table shown in FIG. In FIG. 5, information related to a communication terminal provided by a telecommunications carrier operating a wireless communication network and capable of grasping various information including TAC by the communication system 1 is stored.

  The information shown in FIG. 5 stored in the terminal information storage unit 15 is the basis for determining in the SMS distribution necessity determination unit 13 whether or not to notify the communication terminal of the service provided by the wireless communication network. Information. The SMS distribution necessity determination unit 13 determines, for each model, whether or not to notify the communication terminal of the service provided by the wireless communication network. Therefore, the determination is performed using the TAC, which is information for specifying the model included in the terminal identification information provided from the communication terminal. The information shown in FIG. 5 is basic information at that time. In addition, as described above, when there is a possibility that a communication terminal having the same TAC as a communication terminal related to a communication carrier operating a wireless communication network may be provided by another person, the information shown in FIG. The TAC and other information may be combined to determine whether to notify the communication terminal about the service provided by the wireless communication network. In the table shown in FIG. 5, the various types of information related to the communication terminals for each model are associated with the TAC because they are used when there is an exceptional condition regarding the necessity of SMS distribution. Note that the information shown in FIG. 5 is information provided from a communication carrier or the like, and is updated when the model of the communication terminal related to the communication carrier is updated.

  In addition, the format of the information memorize | stored in the terminal information storage part 15 is not limited to the format shown in FIGS. For example, one piece of information combining the information shown in FIG. 3 and the information shown in FIG. 4 may be prepared.

  Next, processing related to location registration of the communication terminal 40 in the communication system 1 will be described with reference to FIGS. 6 and 7. FIG. 6 is a sequence diagram for explaining a location registration method for the HSS 10 by the communication terminal 40. FIG. 7 is a flowchart relating to the necessity of SMS delivery in the SMS delivery necessity judgment unit 13 of the HSS 10.

  As shown in FIG. 6, first, a location registration request (Attach_Request) is transmitted from the communication terminal 40 to the exchange 20 (S01). The exchange 20 performs processing necessary for the location registration request in its own device, and then transmits a location registration request (Dia_ULR / MAP_ULC / MAP_UGL) related to the communication terminal 40 to the HSS 10 (S02). The location registration request from the communication terminal 40 via the exchange 20 includes terminal identification information (in this embodiment, IMEI) that identifies the terminal and user identification information (in this embodiment, a telephone number) that identifies the user. .

  The location registration request receiving unit 11 of the HSS 10 receives the location registration request transmitted from the communication terminal 40 via the exchange 20, and performs an authentication process related to location registration based on the received information (S03). Then, the HSS 10 transmits an authentication completion signal (Dia_ULA / MAP_ULA / MAP_UGA) as a signal in response to the signal (S03) from the exchange 20 to the exchange 20 (S04).

  Further, the SMS distribution necessity determination unit 13 determines whether SMS distribution is necessary for the communication terminal 40 that has transmitted the location registration request (S05).

  An example of a method for determining whether SMS delivery is necessary will be described with reference to FIG. First, the SMS delivery necessity determination unit 13 transmits from the communication terminal 40 the terminal identification information associated with the user identification information stored in the profile (see FIG. 3) stored in the terminal information storage unit 15. It is determined whether or not the telephone number corresponding to the user specifying information included in the location registration request matches the combination of IMEI corresponding to the terminal identification information (S11). More specifically, when the combination of IMEI and telephone number included in the location registration request transmitted from the communication terminal 40 is stored in the profile information stored in the terminal information storage unit 15 (S11-YES) Since the communication terminal 40 is a communication terminal for which processing related to location registration has been performed in the past, it is determined that SMS distribution for notifying the service provided by the wireless communication network is unnecessary, and processing related to SMS distribution is performed. Not performed (S12). On the other hand, when the IMEI included in the location registration request transmitted from the communication terminal 40 is not stored in the profile information stored in the terminal information storage unit 15 (S11-NO), the location registration by the communication terminal 40 is not performed. Indicates that it was done for the first time. Therefore, SMS delivery may be necessary.

  At this stage, the SMS distribution necessity determination unit 13 also refers to the information shown in FIG. 4 stored in the terminal information storage unit 15 and has performed location registration in the past (currently changed) IMEI. And a combination of telephone numbers may be referred to. Note that, referring only to the information shown in FIG. 4, the terminal identification information (IMEI) associated with the user identification information (telephone number) and the user identification information included in the location registration request transmitted from the communication terminal 40 ( It may be configured to determine whether or not a combination of (telephone number) and terminal identification information (IMEI) matches.

  Next, referring to the TAC included in the IMEI included in the location registration request transmitted from the communication terminal 40, it is determined whether the TAC matches the information stored in the terminal information storage unit 15 (see FIG. 5). (S13). When the TAC of the communication terminal 40 is not stored in the terminal information storage unit 15 (S13-NO), it indicates that the model corresponding to the TAC is not a communication terminal related to the communication carrier of the wireless communication network. . Therefore, it is determined that SMS distribution for notifying about the service provided by the wireless communication network is necessary (S15). On the other hand, when the TAC of the communication terminal 40 is stored in the terminal information storage unit 15 (S13-YES), the above-described exceptional situation, that is, a situation where a communication terminal having a common TAC is also provided by others. If there is no such message, it may be determined that SMS distribution is unnecessary. However, in this embodiment, a case where an exceptional situation exists will be described.

  Next, it is determined whether or not the communication terminal 40 corresponds to a communication terminal that requires SMS distribution although the TAC stored in the terminal information storage unit 15 matches the TAC of the communication terminal (S14). As one of the determination methods, a determination criterion that SMS is distributed when the specifications of the model satisfy a specific condition is determined in advance, and whether or not SMS distribution is necessary is determined based on whether or not the criterion is met. There is a method to do. In the example illustrated in FIG. 7, a determination criterion that SMS is distributed when an OS that is one of the specifications of the communication terminal is of a predetermined type is determined in advance, and corresponds to the TAC of the communication terminal 40. The information stored in the terminal information storage unit 15 is referred to to confirm whether the OS is a predetermined type. As a result, when the OS of the communication terminal 40 is an OS requiring SMS distribution (S14-YES), it is determined that SMS distribution is performed (S15). On the other hand, when the OS of the communication terminal 40 is different from the OS that requires SMS delivery (S14-NO), it is determined that SMS delivery is unnecessary (S12). As described above, even when the TAC stored in the terminal information storage unit 15 matches the TAC of the communication terminal, it is necessary to combine the other information such as the information related to the specification of the communication terminal to distribute the SMS. It can be set as the structure which determines NO.

  Returning to FIG. 6, the SMS distribution processing unit 14 of the HSS 10 performs processing related to SMS distribution for the communication terminal 40 that is determined to distribute SMS as a result of the SMS distribution necessity determination (S05). The SMS distribution processing unit 14 transmits an SMS distribution request to the SMS distribution device 30 (S06). The SMS distribution request includes information for specifying the destination communication terminal 40 (for example, a telephone number) and information related to text to be transmitted as SMS. In addition, when the content of SMS is common regardless of a communication terminal, the information regarding the text transmitted as SMS may be transmitted with respect to the SMS delivery apparatus 30 previously.

  Then, the SMS delivery device 30 delivers the SMS to the communication terminal 40 based on the SMS delivery request from the HSS 10 (S07). This SMS includes information for specifying a service provided by the wireless communication network of the communication system 1. Therefore, when receiving the SMS from the SMS distribution device 30, the communication terminal 40 can execute a necessary process based on the information described in the SMS. Note that, as a result of the SMS distribution necessity determination (S05), for the communication terminal 40 determined to be unnecessary for SMS distribution, the process related to SMS distribution is not performed, and only the necessary process related to location registration is performed.

  As described above, the HSS 10 corresponding to the information management apparatus according to the present embodiment acquires IMEI as terminal identification information for specifying a communication terminal when receiving a registration request to the wireless communication network from the communication terminal 40. . Then, based on whether or not the information (TAC) specifying the model included in the IMEI as the terminal identification information matches the information stored in the terminal information storage unit 15 of the HSS 10 in advance, Thus, it is determined whether or not to notify information related to the service provided in the wireless communication network, and when it is determined to notify, the communication terminal 40 is notified by SMS distribution. In the HSS 10, by having the above-described configuration, for example, a communication terminal that does not hold information related to a service provided by a wireless communication network, such as a SIM lock-free terminal, transmits a registration request to the wireless communication network. Even so, information related to the service can be appropriately provided to the communication terminal.

  Also, with the above configuration, it is possible to prevent information related to a service provided on the wireless communication network from being distributed to all communication terminals that transmit a registration request. Specifically, the notification of the service can be suppressed for a communication terminal that is assumed to hold information related to the service provided in the wireless communication network in advance. Therefore, since it is possible to provide information by selecting a communication terminal considered to require information, it is possible to prevent an increase in processing amount due to distribution of unnecessary information.

  Further, like the HSS 10 described above, the terminal information storage unit 15 stores information specifying the specification of the communication terminal of the model in association with the information specifying the model (TAC), and is included in the terminal identification information. Whether or not to deliver the SMS based on the specifications of the communication terminal, when the information (TAC) for identifying the model to be transmitted matches the information stored in the terminal information storage unit 15 of the HSS 10 in advance. It has the structure to judge. In this way, by having a configuration for determining whether or not to deliver SMS based on the specifications of the communication terminal, for example, for a communication terminal having a specific specification, information on the service Even when it is necessary to provide the information, it can be provided appropriately.

  Further, the HSS 10 stores a combination of user identification information and terminal identification information received in the past for registration requests stored in the terminal information storage unit 15, and uses this to determine whether SMS distribution is necessary. ing. Specifically, the combination of the user identification information and the terminal identification information included in the location registration request from the communication terminal 40 received by the location registration request receiving unit 11 is the location registration request stored in the terminal information storage unit 15. If it matches the combination of user identification information and terminal identification information received in the past (matches the information shown in FIG. 4), it does not correspond to a communication terminal that needs to notify the service provided by the wireless communication network By adopting the determination configuration, it is possible to prevent a similar message from being notified again to a communication terminal that has received a registration request in the past. Therefore, it is possible to notify information related to services available on the wireless communication network while preventing an increase in communication volume.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  For example, the HSS 10 (information management device) described in the above embodiment may be configured by combining a plurality of devices. Further, a plurality of devices included in the communication system 1 may be realized by a single device. For example, the HSS 10 may also have the function of the SMS distribution device 30. That is, the HSS 10 may be an apparatus integrated with an apparatus having other functions.

  Moreover, although the case where HSS10 was provided with the function as an information management apparatus was demonstrated in the said embodiment, another apparatus may have a function as an information management apparatus. The other device that can be equipped with a function as an information management device is preferably a device that participates in processing related to registration when a communication terminal to which a USIM is attached connects to a network.

  Further, in the above-described embodiment, a case has been described in which three-stage determination (S11, S13, S15) is performed as illustrated in FIG. However, the HSS 10 functioning as an information management apparatus refers to at least the TAC included in the IMEI included in the location registration request transmitted from the communication terminal 40, and the information (the TAC is stored in the terminal information storage unit 15) It suffices to make a determination (S12) to determine whether or not it matches (see FIG. 5). By providing at least the above-described configuration, it is possible to appropriately notify a communication terminal that needs information related to a service provided by a wireless communication network.

  Moreover, in the said embodiment, the structure which performs the determination using the information which specifies the specification for every model of a communication terminal in the determination of the 3rd step of the determination (S11, S13, S15) of 3 steps shown in FIG. However, the determination at the third stage may be performed without using the information specifying the specification for each model of the communication terminal. For example, in the second stage (S13), the information related to the service provided in the wireless communication network is referred to by referring to the TAC included in the terminal identification information and determining whether the TAC matches the information stored in the terminal information storage unit 15. However, this information can also be used. That is, for the TAC information stored in the terminal information storage unit 15, if it is a terminal that requires service notification, a flag indicating that is given, and after the second stage determination, It may be configured to determine whether or not to notify the service by determining the presence or absence of a flag in the TAC information stored in the terminal information storage unit 15. In this case, even if there is no information specifying the specifications for each model of the communication terminal, it is possible to determine the necessity of service notification.

  In the above embodiment, a case has been described in which a service is notified using SMS to a communication terminal that needs to notify a service provided by a wireless communication network. However, a method for notifying a service is different from SMS. It may be a method.
