However, the communication network is formed by more communication nodes, that is, an exchange, a transmission device, a communication terminal, and the like. Of course, these communication nodes may refer to and update the subscriber information of the subscriber information device 100. It is also conceivable to refer / update the subscriber information of the subscriber information apparatus 100 directly from the communication terminals 400a and 400b.
In the following description, the communication nodes 200a, 200b, and 200c are described as “communication node 200” unless they are particularly distinguished. Similarly, when the communication terminals 400a and 400b are not particularly distinguished and described, they are described as “communication terminal 400”.

[1.2. Subscriber information device]
Next, the configuration of the subscriber information device 100 will be described in detail. The subscriber information device 100 has a general computer hardware configuration. That is, the subscriber information device 100 includes a central processing unit (CPU) that executes a program and controls the entire subscriber information device 100, a storage unit including a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. And a communication interface for controlling the exchange of data via the communication network.

  Various data and programs, that is, software are stored in the ROM and hard disk of the subscriber information device 100. The function unit shown in FIG. 2 has the subscriber information as a result of these software, the function realized by the CPU of the subscriber information apparatus 100 executing the program, and the hardware function of the subscriber information apparatus 100 described above. Implemented in apparatus 100.

  As shown in the figure, the subscriber information device 100 includes a subscriber information storage unit 101, a subscriber information control unit 102, an index unit 103, an event trigger reservation unit 104, an event detection notification unit 105, a determination Part 106. In the present embodiment, the subscriber information device 100 is configured using a single device, but may be configured using a plurality of devices.

The subscriber information storage unit 101 includes a hard disk, an RDBMS (Relational DataBase Management System), and subscriber information in a plurality of types of communication networks. Here, RDBMS is software for managing a relational database (RDB). The RDB is a tabular database, and one data (record) is represented as a set (table format) of a plurality of items (fields). RDB makes it possible to describe a conceptual data model in a tabular format. Further, the subscriber information storage unit 101 stores SQL (Structured Query Language) that is software for performing operations such as search, extraction, deletion, and addition to the RDB.
Note that RDBMS, RDB, and SQL here are general and general, and are not constructed or customized depending on a specific communication control method.

  The subscriber information stored in the RDB includes subscriber information in a PDC mobile communication network, subscriber information in an IMT-2000 mobile communication network, and subscriber information such as Internet service and mail service. . The subscriber information stored in the RDB may include subscriber information based on other communication methods, for example, a communication method such as PHS or W-LAN.

  FIG. 3 shows an example of the data structure of subscriber information stored in the subscriber information storage unit 101. As shown in the figure, the subscriber information includes E.E. “Subscriber identifier” representing a telephone number in 164 format, “Location area” representing the area where the communication terminal 400 specified by the subscriber identifier is present, and “Voice answering phone call seconds” representing the number of answering machine call seconds. Contains. In this example, the “subscriber information identifier” is set to E.E. For example, a SIP URI (Session Initial Protocol Uniform Resource Indicator) may be used.

In addition, the subscriber information is a characteristic item of the present invention that indicates whether or not a third party is allowed to refer to or update the subscriber information. It is configured to include “non-permitted”, “event condition” representing an operation to be executed when the occurrence of a specific event is detected, and “hobby” representing a subscriber's hobby identified by the subscriber identifier.
The subscriber information in the subscriber information storage unit 101 is referred to / updated by the subscriber information control unit 102, the event trigger reservation unit 104, the event detection notification unit 105, and the determination unit 106.

  The index unit 103 stores subscriber information arrangement information in the subscriber information storage unit 101. In addition, when there are a plurality of subscriber information devices 100, arrangement information indicating in which subscriber information device 100 the subscriber information is stored is stored. FIG. 4 shows an example of arrangement information stored in the index unit 103. Even when there is a large amount of subscriber information to be stored in the subscriber information storage unit 101 and the subscriber information storage unit 101 has to be divided into a plurality of subscriber information devices 100 due to memory limitations and the like, the communication nodes 200a and 200b. 200c, or the subscriber information control unit 102, the event trigger reservation unit 104, the event detection notification unit 105, and the determination unit 106 can obtain the arrangement information by making an inquiry to the index unit 103. The arrangement information of the index unit 103 is changed when the arrangement information is changed, such as the introduction of new subscriber information in the subscriber information storage unit 101, the change of the subscriber information arrangement, and the occurrence of a failure of the subscriber information device 100. It is changed by the subscriber information storage unit 101.

  When the determination unit 106 receives an access (reference or update) request to subscriber information stored in the subscriber information storage unit 101, the determination unit 106 determines whether to permit the access. Specifically, the determination unit 106 determines whether the subscriber information control unit 102 and the event trigger reservation are based on “allowing / non-permitting reference / update from a third party” stored in the subscriber information storage unit 101. In response to requests from the unit 104 and the event detection notification unit 105, the admissibility / non-permission of the request is determined.

  Specifically, before registering “baseball” in “hobby” in the subscriber information storage unit 101, the user of the communication terminal 400 b can set “allowing reference / update from a third party” in the subscriber information storage unit 101. -By registering “non-permitted” to “unallow all references from third parties”, it is possible to prevent event notification to the communication terminal 400a when “baseball” is registered as “hobby”. It becomes.

The subscriber information control unit 102 refers to and updates the subscriber information stored in the subscriber information storage unit 101 via the determination unit 106 based on requests from the communication nodes 200a, 200b, and 200c. is there.
The subscriber information control unit 102 includes an access request receiving function 1021 and a subscriber information access function 1022 as functions characteristic of the present invention.

  The access request receiving function 1021 receives access requests for subscriber information from communication nodes 200a, 200b, and 200c belonging to different communication networks by the same protocol for accessing subscriber information. Here, JDBC (Java (registered trademark) Database Connectivity) is used as a protocol for accessing subscriber information. As is well known, JDBC is a software for establishing a connection between a client and a server that manages an RDB using the Java (registered trademark) language, or transmitting an access request for a database including SQL from the client to the server. It is. The JDBC software is stored in the storage unit of the subscriber information device 100.

The subscriber information access function 1022 accesses the subscriber information stored in the subscriber information storage unit 101 in response to the access request received by the access request reception function 1021. Specifically, the subscriber information access function 1022 extracts an SQL sentence included in the access request and passes it to the RDBMS of the subscriber information storage unit 101.
The event trigger reservation unit 104, based on the request from the communication nodes 200a, 200b, 200c, the value related to the “event condition” in the subscriber information stored in the subscriber information storage unit 101 via the determination unit 106. Is referred to and updated. Specifically, when the event trigger reservation unit 104 receives from the communication nodes 200a, 200b, and 200c a registration request for information indicating an event that should be detected and an operation that should be executed upon detection of the event occurrence. The “event condition” in the subscriber information storage unit 101 is updated with the received information.

The event detection notification unit 105 detects the occurrence of a registered event by referring to a value related to “event condition” in the subscriber information stored in the subscriber information storage unit 101 via the determination unit 106. In this case, an operation registered as an operation to be executed is performed.
Specifically, the event trigger reservation unit 104 stores information indicating “notify the communication node 200c when the communication terminal 400a enters Tokyo” in the “event condition” of the communication terminal 400a of the subscriber information storage unit 101. If the communication terminal 400a moves into Tokyo and the “location area” of the communication terminal 400a stored in the subscriber information storage unit 101 is updated to “Tokyo”, the event detection notification The unit 105 notifies the communication node 200c accordingly. Accordingly, the communication terminal 400 on the Internet that can access the communication node 200c can display the fact on the display.

  Further, when the event trigger reservation unit 104 stores information indicating “notify the communication terminal 400b when baseball is registered as a hobby” in the “event condition” of the communication terminal 400b of the subscriber information storage unit 101, When “baseball” is registered in the “hobby” of the subscriber information storage unit 101 in response to a request from the communication terminal 400a, the communication node 200b is notified of the registration and the subscriber identifier of the communication terminal 400a. Can be displayed on the display of the communication terminal 400b.

In addition, when performing these processes, the communication channel setting between the communication terminals 400 is not required. As the subscriber information is changed, the program stored in the subscriber information device 100 is started, so that the event detection notification unit 105 functions and executes processing. It is also possible to specify time as an event condition. In this case, the event detection notification unit 105 connects to a necessary device such as a clock device and uses information supplied from the connected device. Event detection and notification.
In this way, subscriber information of multiple types of communication networks can be cross-referenced and updated in multiple types of communication networks, so that subscriber information based on mobile communications can be reflected in other services, The mobile communication can be controlled by the service subscriber information.

[1.3. Communication node]
Next, the configuration of the communication nodes 200a, 200b, and 200c will be described. The communication nodes 200a, 200b, and 200c have a general computer hardware configuration, and software for realizing the functions of the communication nodes 200a, 200b, and 200c is stored in the memory.

  The communication nodes 200a, 200b, and 200c belong to different communication networks. In the present embodiment, the communication node 200a belongs to the PDC network and is a control device in the PDC network. As shown in FIG. 5, the communication node 200 a includes a mobile communication control unit (PDC) 201. The mobile communication control unit (PDC) 201 has only a communication control function specific to PDC mobile communication among the subscriber information management function and communication control function provided in the conventional PDC-HLR station. The mobile communication control unit (PDC) 201 has a function of executing a Java (registered trademark) program and a function of accessing a database using the JDBC. Further, as shown in FIG. 6, the communication node 200a includes a PDC exchange, and communicates with a mobile communication control unit (PDC) 201 by a PDC-MAP.

  The communication node 200b is assumed to be a control device in the IMT-2000 network. As illustrated in FIG. 5, the communication node 200 b includes a mobile communication control unit (IMT) 202. The mobile communication control unit (IMT) 202 has only a communication control function specific to IMT mobile communication among the subscriber information management function and the communication control function provided in the conventional IMT-HLR station. In addition, the mobile communication control unit (IMT) 202 has a function of executing a Java (registered trademark) program and a function of accessing a database using the JDBC. Further, as shown in FIG. 6, the communication node 200b includes an IMT exchange, and communicates with the mobile communication control unit (IMT) 202 by GSM-MAP.

  The communication node 200c is assumed to be a service control device in the Internet network. The communication node 200c is a general httpserver. The communication node 200c includes a service control unit 203 as shown in FIG. The service control unit 203 has only a service control function among the subscriber information management function and the service control function provided in the conventional service subscriber information management apparatus. The service control unit 203 has a function of executing a Java (registered trademark) program and a function of accessing a database using the JDBC. The communication node 200c provides a web service to the communication terminals 400a and 400b via the Internet.

  FIG. 6 shows a conceptual diagram of a communication control network system according to the present invention. As shown in the figure, the subscriber information device 100 collectively manages subscriber information in a plurality of types of communication networks using a tabular database. The communication node 200a that belongs to the PDC network, the communication node 200b that belongs to the IMT network, and the communication node 200c that belongs to the Internet network use the subscriber information access protocol such as JDBC to update the subscriber information of the subscriber information device 100. It is configured to be commonly accessible.

[2. Operation]
Next, an operation example of the communication control method using the above-described subscriber information device according to the present embodiment will be described.
(2.1. Example of access to subscriber information)
First, the operation when the communication terminal 400a inquires the subscriber information of the communication terminal 400b will be described.
Here, the communication terminal 400a is a PDC terminal, and the subscriber identifier of the communication terminal 400a is “090-aaaa-bbbb”. The communication terminal 400b is an IMT-2000 terminal, and the subscriber identifier of the communication terminal 400b is “090-cccc-dddd”. Further, it is assumed that the subscriber information storage unit 101 of the subscriber information device 100 stores the subscriber information shown in FIG. Further, it is assumed that a JDBC connection is established in advance between the subscriber information device 100 and the communication node 200a.

FIG. 7 shows a sequence when the communication terminal 400a makes a call to inquire about the subscriber information of the communication terminal 400b. In steps S10 and S20, a signal at the time of calling is transmitted to the communication node 200a via the radio base station 300a.
In step S30, when there are a plurality of subscriber information devices 100, the communication node 200a refers to the index unit 103 in the subscriber information device 100, and the subscriber in which the subscriber information of the communication terminal 400b is stored. The information device 100 is specified.

Next, the communication node 200a generates an access request message including an SQL sentence for obtaining the subscriber information of the communication terminal 400b.
In step S40, the communication node 200a transmits the generated access request message to the identified subscriber information device 100 via a pre-established JDBC connection.
In step S50, the access request receiving function 1021 of the subscriber information device 100 receives an access request message from the communication node 200a by the JDBC. The subscriber information access function 1022 interprets the SQL statement included in the access request message. The subscriber information access function 1022 inquires of the determination unit 106 whether or not the communication terminal 400a can inquire about the subscriber information of the communication terminal 400b.

  The determination unit 106 refers to the subscriber information storage unit 101 to determine whether or not the communication terminal 400a is allowed to refer to the subscriber information of the communication terminal 400b. Here, as shown in FIG. 3, “allowing / non-permitting reference / update from third party” corresponding to “subscriber identifier” “090-cccc-dddd” of communication terminal 400b is “090-aaaa-”. Since only “bbbb is all permitted” and “090-aaaa-bbbb” is a subscriber identifier of the communication terminal 400a, the determination unit 106 transmits the subscriber information of the communication terminal 400b to the communication terminal 400a. Judge that reference is allowed.

Note that the determination unit 106 refers to the arrangement information of the index unit 103 and specifies the storage location in the subscriber information device 100 or the subscriber information storage unit 10101 in which the subscriber information of the communication terminal 400b is stored. There can be.
The determination unit 106 passes the SQL sentence to the subscriber information storage unit 101. The subscriber information storage unit 101 searches for and extracts the subscriber information of the communication terminal 400b according to the SQL sentence. The subscriber information storage unit 101 returns the extracted subscriber information to the subscriber information control unit 102 via the determination unit 106.

In step S60, the subscriber information control unit 102 transmits the subscriber information of the communication terminal 400a to the communication node 200a using the JDBC.
In step S70, the communication node 200a receives the subscriber information of the communication terminal 400b by the operations in steps S40 to S60. Here, the communication node 200a transfers the received subscriber information to the communication terminal 400a via the radio base station 300a.

In this way, the communication terminal 400a can refer to and update not only the subscriber information of the communication terminal 400a itself but also the third party subscriber information that adopts a different communication method. Also, information that has not been used in conventional mobile communication, such as hobbies and current feelings, can be referred to and updated at the same time.
In this operation example, the communication terminal 400a makes a call and the communication terminal 400a itself receives the subscriber information. However, the subscriber information is transmitted to the communication terminal 400b via the communication node 200b, It is also possible to transmit subscriber information to the communication node 200c.

Even in such a case, each of the communication nodes 200a, 200b, and 200c can receive subscriber information using a unified protocol for accessing subscriber information called JDBC. For this reason, even when each communication node 200 transfers subscriber information to the communication terminal 400 via the communication nodes 200 belonging to different communication networks after step S70, the communication method of the called party that could not be achieved conventionally. It is possible to change the communication control contents in accordance with the optimal communication control according to the situation and the state of the called party.
As described above, the user can receive and receive subscriber information in a plurality of types of communication networks and provide services related to the subscriber information, and can receive various services using the subscriber information. Become.

(2.2. Examples of services using subscriber information devices)
Next, a service example using the subscriber information apparatus 100 according to the above-described embodiment will be described.
As a premise, it is assumed that the subscriber information storage unit 101 stores the subscriber information shown in FIG. The communication terminal 400a is a PDC terminal, and the subscriber identifier of the communication terminal 400a is “090-cccc-dddd”. The communication terminal 400b is an IMT-2000 terminal, and the subscriber identifier of the communication terminal 400b is “090-eeee-ffff”. Further, it is assumed that a JDBC connection is established in advance between the subscriber information device 100 and the communication node 200a.

FIG. 8 shows that the user of the communication terminal 400a updates his / her subscriber information “hobby” to “baseball”, and “baseball” is registered as “event condition” “hobby” set in advance by the user of the communication terminal 400b. This shows a sequence in which “notify 090-eeee-ffff” and “notify communication terminal 400b”.
In steps S110 to S190, the communication terminal 400a updates its own subscriber information stored in the subscriber information device 100 using the communication network of this embodiment.

Specifically, in step S110, the communication terminal 400a transmits a request for updating the “hobby” of the subscriber information of the terminal 400a to “baseball” by the user's operation. In step S120, the radio base station 300a transmits an update request to the communication node 200a in accordance with the PDC communication method.
In step S130, the communication node 200a generates an access request message including an SQL sentence for updating the subscriber information of the communication terminal 400a.

In step S140, the communication node 200a transmits the generated access request message to the subscriber information device 100 via a pre-established JDBC connection.
In step S150, the access request receiving function 1021 of the subscriber information device 100 receives an access request message by the JDBC.

The subscriber information access function 1022 interprets the SQL sentence included in the access request message, and inquires of the determination unit 106 whether the subscriber information of the communication terminal 400a can be updated.
Since the received request is an update request for the subscriber information of the communication terminal 400a itself, the determination unit 106 determines that the update is possible. The determination unit 106 passes the SQL sentence to the subscriber information storage unit 101. The subscriber information storage unit 101 searches for subscriber information including the subscriber identifier “090-cccc-dddd” of the communication terminal 400a according to the SQL sentence, and updates “hobby” of the searched subscriber information to “baseball”. To do.

When the update process is performed, the event detection notification unit 105 detects an event that the “hobby” of the subscriber information of the communication terminal 400a is updated to “baseball”. The event detection notification unit 105 transmits a subscriber information search request including an “event condition” that matches the event to the determination unit 106.
Since the “permission / non-permission of reference / update from a third party” of the subscriber information of the communication terminal 400a is “all permissible”, the determination unit 106 joins the communication terminal 400a to all the communication terminals 400. It is determined that notification of event occurrence related to person information is permitted. The determination unit 106 passes to the subscriber information storage unit 101 an SQL statement for searching for subscriber information including a matching “event condition”.

  Here, since the subscriber information shown in FIG. 9 is stored in the subscriber information storage unit 101, the subscriber information storage unit 101 uses “event condition” “baseball as a hobby as matching subscriber information. When registered, subscriber information including “notify 090-eeee-ffff” is extracted and passed to the event detection notification unit 105. The event detection notification unit 105 interprets the operation content set in the “event condition” of the subscriber information, and executes an operation in accordance with the content.

Here, in steps S210 to S230, the event detection notification unit 105 has said that baseball has been registered as a hobby using the JDBC for the communication terminal 400b identified by the subscriber identifier “090-eeee-ffff”. Notification of event occurrence.
In this way, it is possible to provide a service by dynamically changing subscriber information to the communication terminals 400 belonging to any communication network.
Note that when the communication terminal 400a does not allow the communication terminal 400b to refer to the subscriber information, the determination unit 106 prevents detection by the event detection notification unit 105, and thus steps S210 to S230 do not occur.

  Thus, by separating the conventional subscriber information storage unit of the HLR station from the communication control unit, the subscriber information storage unit 101 can be constructed independent of the communication method. For this reason, regardless of the communication method and the type of service, the subscriber information can be cross-referenced and updated, and various services can be provided. Further, since it becomes possible to construct the subscriber information apparatus 100 using a general-purpose product that does not depend on the communication system in the market, such as a JDBC or RDBMS, the subscriber information apparatus 100 can be shared and a communication network can be constructed. This can contribute to cost reduction.

  As described above, in the past, subscriber information in various services such as PDC, IMT-2000, and the Internet could not be cross-referenced and updated, but in the present invention, it does not depend on the communication method. It was possible by using various methods and protocols.

[3. Modified example]
Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made within the scope of the technical idea. As modifications, for example, the following can be considered.
(1) In the above-described embodiment, it has been described that the JDBC is used as a protocol for accessing the subscriber information storage unit 101. However, the present invention is not limited to this, and the subscriber information storage is common to different types of communication networks. Any protocol that can access the unit 101 may be used. For example, ODBC (Microsoft open Database Connectivity) or XML (Extensible Markup Language) may be used. A database access protocol that may be developed in the future may be used.
Further, the database for managing the subscriber information in the subscriber information storage unit 101 is not limited to the RDB. For example, when XML is used as a communication protocol, a native XML database can be used as a database for managing subscriber information in the subscriber information storage unit 101.

(2) In the above-described embodiment, the PDC network, the IMT-2000 network, and the Internet have been described as examples of the plurality of types of communication networks. However, for the types of communication networks, subscriber information is managed separately. Any communication network may be used. For example, a PHS network or a fixed network may be included.
(3) The subscriber information stored in the subscriber information storage unit 101 is an example, and information regarding various subscribers can be included. For example, information such as “current feeling” and “current state” may be included.

(4) In the above-described operation example, it has been described that a JDBC connection is established in advance between the subscriber information device 100 and the communication node 200a. However, the present invention is not limited to this. For example, in FIG. In step S40 or step S140 in FIG. 8, a JDBC connection may be established for each communication. However, it is advantageous to establish in advance because the amount of signals can be reduced rather than to establish each time for each communication.

  INDUSTRIAL APPLICABILITY The present invention can be used for providing various information services by centrally managing subscriber information in a plurality of types of communication networks and making them easily accessible without depending on communication methods.
