Description

Method for providing group communication service using group identifier and system thereof

The present invention relates to a method and system for providing a group communication service using a group identifier. More specifically, it relates to a method and system for generating a single group Uniform Resource Identify (URI) representing multiple users using XML Configuration Access Protocol (XCAP) technology.

XCAP technology, one of the most actively discussed issues, is a technology for registering user configuration information for a specific application service in the XCAP server and directly managing the information registered in the server from the XCAP client.

Since the XCAP technology can register and manage user setting information directly by an XCAP client, that is, a user, it can be used for group communication service to facilitate frequent user registration and change of group information.

Group information of the group communication service is described in XML (eXtensible Markup Language) format and stored in the XCAP server.

Here, the group communication service refers to a service that registers users who want to communicate with a specific group and calls each registered group to simultaneously call each user belonging to the specific group.

At this time, an identifier for designating a specific group is called a group Uniform Resource Identify (URI).

The group URI is divided into 'global group URI' and 'user group URI' according to the database location of the XCAP server where the group URI is stored.

The global group URI is stored in a global database location on the XCAP server that can be accessed by multiple users at the same time. What is stored in the global database location is the same for other users if it is changed by a particular user.

User group URIs are stored in a database location on the XCAP server specific to each user. Database location specific to each user can only be accessed by that user.

Conventionally, 'user group URI' is mainly used for group communication service using XCAP technology, and the use of 'global group URI' is not activated.

The Global Group URI is not available to the general user because access to the global database location itself is only allowed for specific users, for example service administrators.

However, in the case of providing a group communication service using a 'user group URI' as in the related art, when a user adds a member to his group information, the changed group information should be delivered to all member users belonging to the group. Because the changed group information is stored in the database space assigned to the user, to apply the changed group information to the other users belonging to the changed group, the other users must also change the changed group information in the database space allocated to each user. This is because a registration process is required.

Therefore, in the case of storing group information in a database location specific to a user as in the related art, a procedure of notifying all of the group members and a group information changing procedure of all group members must be performed each time the group information is changed. There is a problem of hassle and waste of radio resources. In addition, since group information of the same content is stored for each user, there is a problem in that database space is wasted due to storage of duplicate content.

On the other hand, when managing group information using a global database, a collision may occur due to simultaneous access of several users. Here, the collision means that modifications between the group members collide with each other for the same group information. For example, if user A changes group information after user A changes group information, the changes made by user A may be deleted. This conflict is because the 'global group URI' conventionally does not contain information that can identify users. Therefore, in order to manage group information using a global database, there is a need for a method for resolving conflicts among users.

Accordingly, an object of the present invention is to provide a method and system for providing a group communication service using a group identifier for managing group information in a global database space that can be accessed by multiple users at the same time.

Group communication service providing method according to a feature of the present invention in order to achieve the above problems,

A method for providing a group communication service for simultaneously calling each group member terminal belonging to a group, the method comprising: representing a group consisting of the group member terminals according to a request of a user terminal, and not being specific to each user and simultaneously accessible by multiple users Registering group information using a group identifier stored in a database space; Receiving information about a group member of a corresponding group for which group communication is requested using the registered group identifier; And providing information about a group member of the corresponding group searched based on the requested registered group identifier.

Group communication service providing system according to a feature of the present invention,

A system for providing a group communication service for simultaneously calling each group member terminal belonging to a group, wherein the group information database stores group information on a group identifier stored in a database space which is not specific to each user and is accessible to multiple users at the same time. ; And to a group member of the corresponding group, which the user terminal requests for group communication using the group identifier in response to a request of a server for generating and storing group information on the group identifier according to a request of the user terminal and processing a group communication call. It includes a group information management server to retrieve and provide information about.

According to the present invention, since the group information is managed using the global group URI, each user does not need to update his or her group information whenever the group information is changed, thereby simplifying the procedure and the waste of radio resources. have.

In addition, since each user can create a unique global group URI, it is possible to solve the conventional problem that the changes of each user may conflict.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, terms such as “… unit”, “… module” described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

Now, a method and system for providing a group communication service using a group identifier according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a group communication service providing system according to an embodiment of the present invention.

According to FIG. 1, a group communication service providing system includes a user terminal 100, a group communication call processing server 200, a group information management system 300, and a plurality of group member terminals 401, 403, and 405. .

The user terminal 100 is a terminal capable of generating group information representing a plurality of users wishing to communicate with the group information management system 300 by performing an XML Configuration Access Protocol (XCAP) client function.

The group communication call processing server 200 performs call processing for group communication with a plurality of group member terminals 401, 403, and 405 belonging to group information requested by the user terminal 100. The group communication call processing server 200 may refer to a call state control function (CSCF) of an IP multimedia subsystem (IMS).

The group information management system 300 performs an XCAP server function to perform group information management to generate, modify, delete, and store group information requested by the user terminal 100. At this time, a global group URI generated in a global database location where the storage location of the group information is not specified for each user is used as the identifier representing the group information.

The group member terminals 401, 403, and 405 are terminals of group members belonging to the global group URI registered by the user terminal 100 in the group information management system 300.

FIG. 2 is a block diagram illustrating a detailed configuration of the group information management system of FIG. 1.

According to FIG. 2, the group information management system 300 includes a group information database 320 and a group information management server 340.

The group information database 320 stores group information about group members designated for each global group URI in a global database location where the storage location of the group information for each user is not specified.

The group information management server 340 generates a global group URI requested by the user terminal 100, configures group information about the group information, and stores the group information in the group information database 320. The group information management server 340 modifies and deletes the stored group information at the request of the user terminal 100.

The group information management server 340 obtains group member information corresponding to the global group URI received from the group communication call processing server 200 from the group information database 320 and receives the group member information obtained from the group communication call processing server ( 200).

The group information management server 340 may include a generation module 342 and an extraction module 344 according to more detailed functions.

The generation module 342 generates a global group URI based on the group name received from the user terminal 100 and the “terminal identifier” of the user terminal 100. In this case, the 'terminal identifier' refers to identification information unique to the user terminal 100, and 'Mobile Station International ISDN Number' may be used. 'MSISDN' is a number assigned to a subscriber by WCDMA IMT-2000. Is one of.

The generation module 342 configures group information by receiving information of group members for group information on the generated global group URI from the user terminal 100. The configured group information is stored in the group information database 320.

The extraction module 344 searches the group information database 320 and searches for a specific group requested by the user terminal 100 for group communication based on the global group URI received from the group communication call processing server 200 to search for a specific group. Extract the information.

Now, a process of providing a group communication service through the configuration described with reference to FIGS. 1 and 2 will be described.

3 is a flowchart illustrating a group communication service providing method according to an embodiment of the present invention.

According to FIG. 3, the user terminal 100 of FIG. 1 requests group information generation to the group information management system 300 of FIG. 1 (S101). In this case, the group information generation request uses a PUT method for generating and modifying data in the XCAP communication method. In addition, XCAP communication messages have a GET method for data inquiry and a DELETE method for data deletion.

The group information management system 300 generates and stores the group information requested in step S101 using the global group URI (S103).

When the generation and storage of the group information is completed in step S103, the group information management system 300 responds to the request for generating group information to the user terminal 100 (S103).

Thereafter, the user terminal 100 requests group communication for a specific group registered through steps S101 to S103 (S107). At this time, the group communication request including the global group URI for the specific group is delivered to the group communication call processing server (200 of FIG. 1).

The group communication call processing server 200 requests (S109) and receives group member information on the global group URI from the group information management system 300 (S111).

The group communication call processing server 200 requests group communication to the group members (401, 403 and 405 of FIG. 1) belonging to a specific group requested by the user terminal 100 using the group member information received in step S111. (S113, S115).

When the group members (401, 403, 405 of Figure 1) in response to the group communication request (S117, S119) for the group communication between the user terminal 100 and the group members (401, 403, 405 of Figure 1) Call connection is made.

4 is a flowchart illustrating a group information registration process according to an exemplary embodiment of the present invention in detail, and illustrates a detailed procedure of steps S101 to S103 of FIG. 3.

According to FIG. 4, when a request for generating group information is received (S201), a group name for a specific group requested is received (S203).

In operation S205, the terminal identifier of the terminal requesting generation of group information is checked. In this case, the terminal may request 'MSISDN' of the terminal and generate the group information.

Next, a global group URI is generated based on the group name and the terminal identifier input and confirmed in steps S203 and S205 (S207).

Then, group information is generated and stored on the basis of the information of the group members input by the terminal requesting generation of group information with respect to the generated global group URI (S209).

FIG. 5 is a flowchart illustrating a detailed process of extracting group information according to an exemplary embodiment of the present invention, and illustrates a detailed procedure of steps S109 and S111 of FIG. 3.

According to FIG. 5, the group information management system 300 of FIG. 1 receives a global group URI for calling a specific group from the group communication call processing server 200 of FIG. 1 (S301).

The group information management system 300 checks the terminal identifier included in the global group URI (S303).

The group information management system 300 searches for corresponding group information with reference to the terminal identifier identified in step S303 (S305).

The group information management system 300 extracts the information of the group members belonging to the group information retrieved in step S305 and delivers it to the group communication call processing server 200 (S307).

FIG. 6 illustrates an XML document including group information according to an embodiment of the present invention, in which group information described with reference to FIGS. 1 to 5 is stored in the form of an XML document.

According to FIG. 6, in group information P100 of user A, a global group URI is defined in “service uri”. Group B of user B (P200) also has a global group URI defined in the “service uri”.

At this time, the global group URI of the user A is defined as 'sip: group000_0103010XXXX@ktf.com' (P101). Similarly, the global group URI of user B is defined as 'sip: group000_0103202XXXX@ktf.com' (P201).

Here, the group name P103 in the global group URI P101 of the user A is composed of 'group000' designated by the user A and '00103010XXXX', which is 'MSISDN' of the user A terminal.

In addition, in the global group URI P201 of the user B, the group name P203 includes 'group000' designated by the user B and '00103202XXXX' which is 'MSISDN' of the user B terminal.

Therefore, even though both of the user names A and B are designated as 'group000' through the global group URIs P201 and P203 of the user A and the user B, unique group information of each of the users A and B may be defined.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
