Specification

Communication control system, communication control method, communication control device, and communication terminal

TECHNICAL FIELD [0001] The present invention relates to a communication control system, method, apparatus, and communication terminal for a mobile communication network, and more specifically, by user operation or independent control of a communication terminal / device.

The present invention relates to a communication control system, a communication control method, a communication control apparatus, and a communication terminal that manage a plurality of communication terminals / devices forming a PAN (Personal Area Network) as a group and perform communication control.

Background art

[0002] In conventional mobile communication systems such as GSM (Global System for Mobile Communications) and IMT—2000, an IC card called SIM (Subscriber Identity Module) or U SIM (Universal Subscriber Identity Module) (hereinafter, SIM or User management is performed using USIM (collectively referred to as USIM card) (see, for example, Patent Document 1). When a user subscribes to a mobile communication service provided by a mobile carrier, the user can use the mobile communication service by purchasing from the mobile carrier or using the USI M card provided. It becomes.

[0003] Specifically, a user accesses a mobile communication service to which he / she subscribes by using the USIM card, which is a subscriber information storage module, as a communication terminal by attaching the USIM card to the communication terminal. Various services can be used. Specifically, the communication terminal notifies the subscriber information and identification information of the user stored in the installed USIM card to the mobile communication network, and registers the subscriber using the communication terminal. That is, it identifies the owner of the USIM card attached to the communication terminal. For example, in the case of a telephone service, a telephone number given to a user is managed in a mobile communication network in association with a USIM card that is not a communication terminal. That is, when the USIM card is installed in a certain communication terminal, the communication terminal is treated as if it has the user's telephone number, and a call to the telephone number is processed to be received by the communication terminal. . [0004] With such a management method using a USIM card, a user can flexibly select an appropriate communication terminal according to his / her preference and situation, and use the communication terminal as his / her own communication terminal. There is an advantage that you can. In a conventional mobile communication network, the user's attributes (address, name, subscription details, etc.) are usually used as subscriber identification information linked to the USIM card identification information, and the identification information of the communication terminal equipped with the USIM card. It was managed in a one-to-one correspondence with. The mobile communication network also has a location management function to support the movement of the communication terminal. When a location registration is made from the communication terminal, the user who uses the communication terminal, in other words, the communication terminal The subscriber identification information of the owner of the installed USIM card is managed in association with the location information of the communication terminal. Therefore, it is possible to grasp who is the current user of the communication terminal and where it is located.

FIG. 11 is a block diagram showing a system configuration of a conventional mobile communication network. The mobile communication network includes a multimedia communication control subsystem 200, a core network 204, a radio access network 206, a communication terminal 209, and the like. Is done. The communication terminal 209 is equipped with a USIM card 210 as a device for identifying the subscriber of the user in use. The radio access network 206 is an access network that provides a means for the communication terminal 209 to access the core network 204 via a radio section, and includes a base station 207, a base station control device 208, and the like.

[0006] The core network 204 is a network and control system that performs transmission of information between communication terminals, connection control, communication management, and the like, and includes location management information of the communication terminals and subscribers of users who use the communication terminals. VLR / HL R (Visited Location Register / Home Location Register 205) is a location management server that manages information etc.

[0007] In addition, the multimedia communication control subsystem 200 is a subsystem intended to realize an additional function for providing an IP-based multimedia communication service on the packet switching system of the core network 204. It is. Multimedia communication control subsystem 200 is an application server AS (Application Server) 201 and CSCF (Call Session Control) that provides a session control function between communication terminals. Function) 202, HSS (Home Subscriber Server) 203, which is a subscriber information management device, and the like.

[0008] SIP (Session Initiation Protocol) is adopted as a session control protocol. CSCF202 provides call and session state control functions between communication terminals, and communicates with users in SIP or HSS203, which functions as a registration server for communication terminals. In addition to registering identification information, it manages and transmits information for controlling the session, and controls session connection.

[0009] Also, an AS 201 is provided that provides a more advanced application service to the user by using the basic functions provided by the multimedia communication control subsystem 200. The CSCF 202 also has interface means for notifying the AS 201 of information on sessions and users / terminals and accepting session control by the AS 201.

[0010] An outline of subscriber information managed by the HSS 203 or the like in a conventional mobile communication network will be described. As shown in FIG. 12, the conventional mobile communication network subscriber information is hierarchically composed of a private identifier, a public identifier, a service profile, and the like. This private identifier is a unique identifier used by the carrier for subscriber management (registration / management of subscribers and available services, authorization for access to services, billing, etc.). Information (ID).

[0011] In FIG. 12, the private identifier is only required to be used in the system so that the carrier can manage his / her subscriber, and for security to protect the subscriber information. It is sufficient that it can be managed outside the system in a private or proprietary information format, for example, managed in a format called NAI (Network Access Identifier). This private identifier also includes a subscriber identification number for the multimedia communication control subsystem 200. In this system configuration, multimedia communication control is provided as a subsystem, so subscriber information for basic communication services such as telephones and subscriber information for multimedia services are managed separately. It is necessary to do this. This private identifier is one for one USIM card Assigned uniquely.

Problems to be solved by the invention

[0018] In such a conventional communication control system, a public identifier made up of address information specified when requesting a call connection or a session connection is managed based on the USIM card and its identification information. There, it was only assumed that one user owns one USIM card and uses one communication terminal equipped with the US IM card. Therefore, services can only be provided on the premise that there is only one terminal owned by the user. This is because there is only one communication terminal that can access the mobile communication network owned by the user, such as a conventional mobile phone, and it is premised on services such as voice calls and simple e-mail! It didn't matter so much.

[0019] However, in the future mobile communication networks, users will be able to access the mobile communication network and its services when high-quality multimedia services and advanced services that combine various functions are provided. Use multiple communication terminals and devices in accordance with the user's situation, service content, communication partner, desired quality, etc., or use them in combination. Therefore, there is a demand to enjoy sufficient service quality and performance.

[0020] For example, when a user owns a plurality of communication terminals or devices! /, The user terminal or the autonomous control of the communication terminals / devices, a small-sized group of communication terminals / devices By forming a network (hereinafter referred to as PAN) and communicating with each other via the PAN, the functions are shared according to their characteristics, and the terminals used by the user are used! It is also considered to transfer calls and sessions according to requests!

[0021] Also, as a service provider or a communication carrier, the same user owns a plurality of communication terminals owned by the user by collectively managing and controlling communication terminals / device groups constituting the PAN as a group. It is possible to provide advanced services that take into account individual attributes and capabilities. By providing services that meet the needs of users as described above, we will improve convenience and improve the characteristics and resource allocation of mobile communication networks.

Even if it could be connected to the network, it could not be used for communication with its performance.

[0024] In addition, in a mobile communication network, it is difficult to handle a group of communication terminals constituting a PAN as a group regardless of whether or not a USIM card is installed, and select an appropriate terminal from the group to make an incoming call. there were. Therefore, combining multiple devices It was difficult to use a hybrid communication service that maximized the capabilities of the terminal.

[0025] The present invention has been made in view of the above circumstances, and in a mobile communication network, an identifier for designating and identifying a communication terminal that does not have a USIM card, and at least a USIM card mounted Combining with the public identifier for one communication terminal, define a new identifier for each communication terminal, and use this to make a connection request specifying a communication terminal that does not have a public identifier. Objective.

[0026] Also, the USIM card contains the profile information necessary for handling the PAN, such as the network configuration of the PAN, the identification information of each communication terminal that constitutes the PAN, and the preference of the communication terminal recommended for use in response to the service. By connecting to the public identifier of the communication terminal and managing it in association with the identifier for the communication terminal so that a plurality of communication terminal groups can be managed as a group, an appropriate communication terminal in the PAN is attached to the USIM card. Regardless of whether or not there is a communication terminal, it is possible to select services freely and flexibly, to use a single service by combining multiple terminals, or to make calls or session establishment requests from other users optimally. It is an object of the present invention to provide a mobile communication system that can make an incoming call.

[0027] In addition, by managing the priority information of communication terminals that are suitable for use according to the type and attributes of services as PAN profile information, it is possible to easily select the optimal communication terminal for a certain service. Providing a mobile communication system that enables users to select and make decisions appropriately, improve user convenience, use services with optimal quality, and effectively use the capabilities of communication terminals.

[0055] Further, the session control means 4a processes a session connection request from a certain user (communication terminal) to another user (communication terminal), and changes the subscriber information of the connection destination user to the subscriber information management means 4b. Obtain and refer to it, and control the connection of the session with the connection destination communication terminal. In addition, the session control means 4a determines whether or not processing by the application server 1 is necessary from the subscriber information and the type and attribute of the requested session, and obtains instructions and information from the application server 1 as necessary. , Control to connect an appropriate session, control session transfer, etc. As in the conventional technology, the application server 1 has advanced malware by functions such as mediating and relaying sessions that require establishment. Provide application services such as multimedia communication services. In addition, when it is necessary to perform complex session control, the session control function 4a is instructed and supported for session connection functions such as control.

FIG. 2 is a diagram for explaining a configuration example of subscriber information (including information for managing PAN) in the present invention. In the subscriber information database 4c, subscriber information of each subscriber to the mobile communication service is stored and stored. Public identifiers, like conventional technologies, are information such as telephone numbers, e-mail addresses, SIP URIs, etc. for identifying and specifying the communication terminal when the communication terminal performs communication control such as call connection and session connection. This is a so-called terminal address.

In addition to the conventional subscriber information, a PAN public identifier may be stored and managed as PAN9 information. The public identifier for PAN is used to collectively specify a group of these communication terminals rather than specifying one of the communication terminals that make up PAN9 and requesting a call connection or session connection.

[0057] Fig. 2 (A) shows an example of a public identifier used for a communication terminal to access a mobile communication network. The PAN profile information (PAN profile) is the disclosure of a communication terminal representing the PAN. It is associated with one or more of identifier 1, public identifier 2, and public identifier 3. The reason why multiple public identifiers are assigned to the same communication terminal is that the identification information / address system and description method differ depending on the type and attribute of the service. For example, a telephone number is used as identification information in a telephone service, and a mail address is used in e-mail. These multiple public identifiers can also be used as, for example, alias addresses (aliases) for the same service type.

[0058] Fig. 2 (B) shows an example of the public identifier assigned to the PAN. The public identifier 4 is used as a public identifier for the PAN that collectively specifies a group of communication terminals constituting the PAN. Two public identifiers 5 are managed. In this example, the PAN profile is associated with one or more of public identifier 4 and public identifier 5. The reason why these multiple public identifiers are assigned as public identifiers for PAN is the same as in the case of public identifiers for communication terminals described above. In the example of Fig. 2 (B), Open identifier 4 is assigned a telephone number, and public identifier 5 is assigned a SIP URI.

[0059] The PAN profile, which is information necessary for managing PAN 9, can be managed in association with a public identifier that identifies the communication terminal, or can be managed in association with a public identifier for PAN. In the case of the former shown in Fig. 2 (B), the PAN profile is associated with one or more of public identifier 1, public identifier 2, and public identifier 3. In the PAN profile, in addition to the same service profile that shows the attributes, types, conditions, etc. of services that can be used as PAN9, the terminal information of communication terminal # 1, communication terminal # 2, communication terminal # 3; 3 and the contents of sessions that can be processed and used by each communication terminal are managed.

Normally, this information is installed in the home domain of the USIM card 10 installed in communication terminal # 1 (a mobile communication network provided by a telecommunications carrier!). Information management means 4b.

[0060] In addition, it is necessary to consider that the network configuration of PAN 9, that is, the communication terminal group constituting PAN 9, is dynamically changed depending on the user's situation and behavior that is not predetermined. Therefore, in order to respond flexibly to the addition and deletion of communication terminals that make up PAN9, the subscriber information management means 4b can manage service profiles, terminal information, etc. managed as PAN profiles in accordance with requests from communication terminals. The configuration can be changed dynamically.

[0061] In this situation, a public identifier that can uniquely identify a terminal is not specified for all terminals, that is, terminals that do not have a USIM card. Therefore, in the present invention, a new identifier (corresponding to the composite identifier of the present invention) is defined by using the public identifier already defined above and the terminal identifier for identifying each terminal. Use.

FIG. 3 is a diagram showing a description example of a public identifier and a terminal identifier used in the present invention. First, public identifiers used for communication control include SIP-URI / terminal IP address / phone number assigned to USIM card, as explained in the background art above. Fig. 3 (A) shows a description example of public identifiers, 311 is a telephone number, 312 is an IP address, and 313 is a SIP URI. In addition to this, the present invention handles terminal identifiers for identifying each terminal including terminals that do not have a USIM card that constitutes PAN9. There are several possible ways to define terminal identifiers.

[0064] Considering sufficient conditions, a terminal identifier is unique (uniquely identifiable) in the entire mobile communication system. The public identifier associated with the USIM card has the ability to satisfy this condition. The object of the present invention is to provide an identifier to a terminal that does not have a USIM card, and therefore cannot be used in the present invention. Therefore, considering the necessary conditions, in the present invention, since all of the terminal identifiers are managed in association with the subscriber information corresponding to the USIM card of the terminal representing the PAN, the terminal identifier is at least inside the PAN. It should be unique. If this is established, it is combined with the public identifier of a communication terminal having a USIM card representing PAN, and the terminal identifier is unique throughout the system. A description example of a terminal identifier that satisfies this condition is shown in Fig. 3 (B).

First, an identifier that is not associated with the USIM card 10 but is managed by the mobile communication network 2 can be considered. An example of this is the International Mobile Station Equipment Identity (IMEI) that corresponds to the individual identification number. 321 is a description example of IMEI. However, IMEI can only use a device that has the ability to behave as an independent terminal in the mobile communication network 2 if the USIM card 10 is installed. However, it can be used to specify a communication terminal that is not attached. In addition, IMEI is guaranteed to be completely unique throughout the mobile communication system! /, But IMEI is used as a terminal identifier and is combined with the public identifier of a communication terminal representing PAN. It can be used as an identifier of the communication terminal.

[0066] Next, although not managed in the mobile communication network 2, it can be used as a terminal identifier that is managed in other places! /. An example of this is the serial number that is connected to the device. Since these are managed and managed in units of manufacturers, they are unique if they are the same devices or devices of the same manufacturer. Therefore, a unique code indicating the ability (for example, known as a bar code system attached to the product) It can be used in combination with the JAN code manufacturer code).

[0067] Next, when the PAN9 is configured, the devices are always connected to each other via a local network, and individual devices are identified in the network. What is managed in the protocol may be used as a terminal identifier. As an example of this, Bluetooth device ID, which is one of the short-range communication methods considered to be used when configuring PAN, USB device ID used when connecting peripheral devices of personal computers, For example, UPnP device ID. 322 is a description example of a Bluetooth device ID.

[0068] Finally, terminal identification information managed independently in PAN9 regardless of the standard may be used as the terminal identifier. There are several ways to define this. First, there is a method of using a name indicating the type or function of the device (eg, TEL, PC, FAX, HEADSET, SPEAKER, ...) as the terminal identifier. 323 is a description example of a name indicating the type or function of the device. In addition, a name (for example, * 001, * 002,...) Indicating the priority order when using the device may be used. 324 is a description example of the name indicating the priority when using the device.

[0069] On the other hand, the name does not have a special meaning, and the device type and priority order cannot be determined by just looking at the name. A unique name within the PAN (for example, bob, lucy, mary,...) May be used. 325 is a description example of an arbitrary unique name. In this case, it is not possible to know the type or capability (function) of the terminal simply by reading the name. To obtain information related to the terminal, it is necessary to make an inquiry to the subscriber information management means 4b. In addition, it is not necessary to expose the information of the terminal managed by the user, and the same name can be assigned to different devices according to the network conditions, so that secure and efficient network operation is possible.

[0070] Next, the configuration of an identifier used to identify a communication terminal that does not have a USIM card in the present invention will be described.

In the present invention, a public identifier unique on the mobile communication network 2 associated with a USIM card 10 that always exists in PAN9, and a unique terminal identifier for recognizing a terminal in PAN9, Create combined information and update it Identifier (equivalent to a composite identifier). As a simple method, the identifier is obtained by concatenating the public identifier and the terminal identifier.

[0071] Further, it is desirable that the identifier is configured so that the information of the public identifier and the information of the terminal identifier can be easily separated and extracted when referring to and interpreting.

Taking these into account, an example of identifier description is shown below.

[0072] Here, the SIP-URI (description method is "SIP: username @ domain name") as the public identifier, and the terminal identifier is a unique name (for example, bob, lucy, mary, ...) The case will be described as a representative example. In addition, at-mark (@), dot) and asterisk (*) are defined as characters that separate words from each other in the description.

[0073] FIG. 4 shows a description example of the destination address. In FIG. 4, the public identifier is “SIP: user name @ domain name”. Address description example 41;! To 414 in Fig. 4 (A) puts an identifier for the terminal between the SIP—URI at sign and the domain name, so the description of the identifier is “SIP: username @ terminal identifier. Domain name ". To separate the public identifier and terminal identifier from this identifier, read the identifier character string in order from the front, and when an at sign comes, the user name is there, and the dot appears after the at sign. Up to the terminal identifier, the dot follows the domain name, and the public identifier is "user name @ domain name".

[0074] Next, in FIG. 4B, address description examples 42;! To 424 place a terminal identifier between the user name and the symbol of the SIP-URI, so the description of the identifier is "SIP: User name.Terminal identifier @domain name ". To separate the public identifier and terminal identifier from this identifier, read the identifier string in order from the front, and when a dot comes, the user name is there, and the at sign appears after the dot. The terminal identifier, the domain name after the at sign, and the public identifier can be obtained as "user name @ domain name" as in Fig. 4 (A).

[0075] Next, in Fig. 4 (C), address description example 43;! -434 puts a terminal identifier at the beginning of the SIP URI, so the description of the identifier is "SIP: terminal identifier. Username @ Domain name ". To separate the public identifier and terminal identifier from this identifier, when a dot comes, it is the terminal identifier, the user name from the back of the dot until the next at sign appears, and the back of the at sign is the domain Similarly, in this example, the public identifier is "User The name is obtained as "@domain name".

As described above, the identifier of the present invention configured by combining the public identifier and the terminal identifier can be used and designated as the destination address of the connection control message from the communication terminal. That is, if the identifier of the present invention is designated as the destination address instead of the conventional public identifier, it is possible to designate a communication terminal that does not have a USIM card as the destination communication terminal.

As another method, FIG. 5 shows a configuration example in which the public identifier and the terminal identifier are individually specified in the destination address in the connection request message.

In Fig. 5 (A), as shown in address description example 511, an information field describing the information disclosure identifier and terminal identifier is provided in the format of the connection request message exchanged between devices. As a result, it is possible to specify in a separated form by including both in the message instead of composing the identifier by combining the public identifier and the terminal identifier.

In this message, since the public identifier and the terminal identifier are stored in different designated positions, it is clear that separation is easy. For example, there is a method of describing a terminal identifier after “pan—device—id =” as a position for describing a terminal identifier. The structure of the connection request message may be defined by syntax rules and grammars such as ASN. 1 (Abstract Syntax Notation One), which is not a physical structure such as the position and length of each field. However, even in this case, it is clear that the present invention can be applied if the position of the public identifier and the terminal identifier is specified in the grammar.

In FIG. 5B, address description example 52;! To 525 are telephone numbers as public identifiers.

(For example, 090-111-222), the case where the terminal identifier is a new name (for example, bob, lucy, mary,...) Is shown. A subaddress field is provided following the position of the public identifier stored in the message, and the terminal identifier is specified in the subaddress field. In this example, it can be considered that the public identifier and the terminal identifier are specified separately, or they are combined to form an identifier, and the identifier is specified as the destination address. You can also. [0080] While typical examples have been described above, various combinations other than the above are conceivable, and public identifiers and terminal identifiers can be specified and easily identified! /. It can be used as an identifier for devices that do not have a USIM card in PAN

[0081] The terminal identifier and the identifier information generated in PAN9 are the same as other parameters, and the U SIM attached to communication terminal # 1, which is a communication terminal representing PAN, is used. It is managed by the subscriber information management means 4b installed in the home domain of the card 10.

FIG. 6 is a diagram for explaining a detailed example of terminal information included in PAN profile information. Here, the description is based on the configuration of FIG. As terminal information, identification information of communication terminal # 1, communication terminal # 2, and communication terminal # 3 included in PAN9 is managed. The terminal information includes a public identifier, a terminal identifier associated with each communication terminal, and an identifier generated in PAN9. Here, as described above, since the identifier can be composed of a public identifier and a terminal identifier, it is not stored as terminal information, and may be generated or determined whenever necessary. .

[0083] The public identifier is address information used in communication control in the mobile communication network, and by referring to this information, the mobile communication network 2, specifically, the communication control device 4, communicates. When connecting to or accessing a terminal, select the wireless access network 5-7 to be used and set the connection route. In addition, by referring to the terminal information together, it is possible to set a connection path to PAN9 and to recognize and manage communication terminals constituting PAN9.

[0084] Next, an example of a connection control method between communication terminals in a mobile communication network to which the present invention is applied will be described. FIG. 7 is a flowchart for explaining an operation example of the session control means 4a when executing the communication control method. FIG. 8 is a diagram showing an example of a session connection with the communication terminals constituting the PAN according to the flow shown in FIG.

[0085] In this example, in response to a session connection request that specifies the public identifier of a communication terminal that constitutes the PAN, the session control means 4a selects an appropriate communication terminal in the PAN 9 according to the requested session type. An example of session connection with a selected communication terminal is shown. In this example, communication terminal # 1, communication terminal # 2, and communication terminal # 3 configure PAN9. It is made.

In FIG. 7, first, the session control means 4a accepts a session establishment request from a communication terminal not included in the group, in which the public identifier of the communication terminal having a USIM card representing PAN9 is designated ( Step S1) refers to the public identifier specified from the subscriber information and its profile information (step S2). Next, at least one communication terminal included in the group is selected, a new identifier is generated by combining the public identifier and the terminal identifier of the selected communication terminal (step S3), and this new identifier is received. A session establishment request is transmitted to the communication terminal selected by designating first (step S4). The flow up to session establishment executed according to the flow shown in FIG. 7 will be specifically described with reference to FIG.

[0087] In FIG. 8, communication terminal # 4 on the calling side designates the public identifier of the communication terminal having a USI M card representing PAN9 on the called side, and the session control means 4a receives the session control means 4a. When a connection request is sent (S11) and session control means 4a receives a session connection request from communication terminal # 4, it refers to the public identifier of the called communication terminal registered in subscriber information management means 4b. Then, it confirms that the public identifier indicated in the session connection request is valid (S 12), and accepts the session connection request.

[0088] Next, when the session control means 4a receives from the subscriber information management means 4b the terminal information associated with the public identifier and the PAN profile information included therein (S13), the PAN profile Referring to FIG. 4, it is recognized that the called communication terminal forms PAN9! /, And the service profile included in the PAN profile is referenced (S14).

[0089] Next, the session control means 4a refers to the type of session connection request from the communication terminal # 4 (type of voice, video, text, etc., or a combination thereof), and the service profile file Confirm that the requested session is available by checking the attributes, types, conditions, etc. of the service indicated in, and determine the type, attributes, etc. of the session to be connected.

[0090] Next, the session control means 4a selects at least one of the communication terminals included in the group (PAN), and performs control to connect the requested session. The selected communication terminal does not have a USIM card, such as communication terminal # 2, that is, a public identifier. Session control means 4a refers to the terminal information included in the PAN profile and generates an identifier that identifies the selected communication terminal # 2 by combining the public identifier and the terminal identifier. (S 15). Then, a session connection request specifying the generated communication terminal # 2 by specifying the generated identifier is sent (S16). When communication terminal # 2 responds to the session connection request (S17), session control means 4a sends a response to the session connection request to communication terminal # 4, and between communication terminal # 4 and communication terminal # 2 Session is connected.

[0091] In the above description, the communication terminal in the selected PAN 9 responds to the session connection request, and the power shown for the connection success example. For example, the communication terminal # 2 is selected as the session connection destination, Attempt to connect session If communication terminal # 2 does not respond (e.g., the user did not respond) or if it refuses connection, communication terminal # 3 is connected to the next connection. It is also possible to connect a session with communication terminal # 3 by sending a session connection request specifying the identifier generated by combining the public identifier and the terminal identifier of communication terminal # 3. .

Next, another example of the flow until session establishment executed according to the flow shown in FIG. 7 will be described based on FIG. What is described here is that the terminal selected by the session control means 4a does not have a USIM card, for example, communication terminal # 3, that is, does not have a public identifier, and does not have mobile communication power. This is the case of a communication terminal that does not have a means to connect to Network 2. The processing of S2 ;! to S24 shown in FIG. 9 is the same as the processing of S1 ;! to S14 4 shown in FIG. The session control means 4a refers to the terminal information included in the PAN profile, and generates an identifier that identifies the selected communication terminal # 3 by combining the public identifier and the terminal identifier (S25). Then, a session connection request specifying the generated communication terminal # 3 with the generated identifier is sent (S26).

Here, it is assumed that communication terminal # 3 can be connected to mobile communication network 2 via communication terminal # 1 among the communication terminals having means for connecting to mobile communication network 2. . This information is transmitted in advance to communication terminal # 1. Communication terminal # 1 receives the session connection request, analyzes the contents, and reaches the destination of the session connection request Is confirmed to be communication terminal # 3, and then transferred to communication terminal # 3 (S27). When communication terminal # 3 responds to the session connection request (S28), the response is transmitted to session control means 4a via communication terminal # 1, and session control means 4a sends a session connection request to communication terminal # 4. And a session is connected between communication terminal # 4 and communication terminal # 3.

[0094] In addition, a session connection request is simultaneously sent to one or more communication terminals capable of processing the requested type of session among the communication terminals constituting the PAN 9, and an appropriate communication terminal responding to the session connection request is transmitted. It is also possible to establish a session between them. Figure 10 shows an example of the flow until such a session is established. In this case, the session control means 4a refers to the terminal information included in the PAN profile and combines the public identifier and the terminal identifier for all the communication terminals that are candidates for the connection destination of the session constituting the PAN9. An identifier is generated, and a session connection request specifying the identifier of these devices is sent simultaneously to each communication terminal.

The processes of S3;! To S35 shown in FIG. 10 are the same as the processes of S1;! To S15 shown in FIG. In the example shown in FIG. 10, a session connection request specifying the respective communication terminals # 1 and # 2 is transmitted by designating the respective identifiers of the communication terminals # 1 and # 2 (S36). When there is a response to the session connection request (S37), the session control means 4a connects the session between the responding communication terminal and communication terminal # 4. At this time, if the session control means 4a accepts a response from one of the communication terminals, the session control means 4a cancels the session connection request to the other communication terminal or receives a response from the other communication terminal. By controlling not to connect a session with the communication terminal, control is performed to ensure that only one session is connected.

[0096] As described above, according to this example, the communication terminal that responds to the call connection request and the session connection request on the called side is selected by the user, not the communication control device, so that the intention and state of the user can be accurately confirmed. Can be reflected in

[0097] Also, according to the configuration of the present invention, in response to a session connection request to PAN9, the session type specified in the session connection request is, for example, a videophone session that is a combination of audio and video. For example, the session control means 4a Select the appropriate communication terminal for each media type, for example, select communication terminal # 1 for the audio session and communication terminal # 2 for the video session, and connect these multiple communication terminals to the session. Thus, it is possible to adapt to the type of session requested by the combination of a plurality of communication terminals, or conversely, it is possible to control so as to divide the session.

[0098] Again, the session control means 4a refers to the terminal information included in the PAN profile for each communication terminal that is determined to be appropriate for each media type and selects the public identifier and the terminal. The identifier is combined to generate an identifier for identifying the communication terminal, and a session connection request specifying this identifier is sent to each communication terminal. In this case, after all the communication terminals selected for each medium respond to the session connection request, the session control means 4a sends a session connection request to the calling communication terminal # 4. And a session for each media is connected between communication terminal # 4 and each communication terminal.

[0099] In the present embodiment, since the connection of a plurality of communication terminals is combined and the session is divided, the content of the service profile managed and stored as the PAN profile is also the communication that constitutes PAN9. It shows the attributes, types, conditions, etc. of services that can be used and provided by appropriate combinations of terminals. In other words, it is shown as a simple set of service profiles for a single communication terminal, not a sum but a composite of these. For example, if PAN9 is configured with a communication terminal that supports only audio and a communication terminal that supports only video, the service profile of PAN9 includes videophone service.

[0100] In the above description, since the selected communication terminal does not have a USIM card and does not have a public identifier, an identifier that identifies the communication terminal is generated by combining the public identifier and the terminal identifier. In the case where the selected communication terminal is a communication terminal having a U SIM card, that is, a communication terminal having a public identifier, the communication terminal can be specified only by the public identifier. As in the conventional case, only the public identifier needs to be specified in the session connection request.

[0101] In the examples described so far, the identifier of the present invention is such that the session control means 4a In the procedure to specify the communication terminals that make up N as the connection destination, a unique identifier was generated and used for the communication terminal in the PAN.

[0102] However, since the identifier of the present invention can be guaranteed to be unique in the mobile communication network, it can be used by any device in the mobile communication network other than the session control means 4a. For example, the communication terminal # 4 can be used as an identifier for designating the called communication terminal used when sending a session connection request. In that case, the calling terminal is a communication terminal included in the called PAN and the USIM is installed! /, NA! /, So normally it cannot be specified as the destination! /, You can call a communication terminal by specifying it as a connection destination for direct communication.

[0103] As described above, even when the calling communication terminal makes a connection request by directly specifying the called communication terminal using the identifier of the present invention, which is not only the public identifier, session control is performed. The means 4a can determine that the communication terminal designated as the callee configures the PAN and change the connection destination to another communication terminal in the PAN.

[0104] As described above, according to the present invention, in a mobile communication network, a terminal that is not attached to a USIM card and that is not associated with a public identifier is the same as a communication terminal that is attached to a USIM card. In this way, it is possible to directly specify the destination as an incoming call and to receive the incoming call. In this way, a communication terminal and a user are not associated with each other in a one-to-one correspondence. It is possible to manage and control transfer and connection destinations between communication terminals.

In addition, it is possible to associate and manage communication terminals with USIM cards that are part of a group such as PAN, and communication terminals that do not have USIM cards. Can be used.

[0105] Further, by referring to the PAN profile information, a communication terminal suitable for the type or attribute of the session or service can be selected and determined. A route suitable for the type and attributes of the session can be determined. Depending on the amount of traffic required for the session, the status of each route, and the transmission capacity, one session can be divided into multiple sessions set on multiple routes for multiple communication terminals, or these multiple sessions can be separated. One session And the ability to switch routes flexibly according to the communication status and route congestion. As a result, it is possible to effectively utilize the resources of the transmission path, particularly the resources of the wireless section.
