Abstract

A method and a system for adding a group member, includes: sending a client corresponding to a user to be possibly added to a group a notification message to confirm whether the user agrees to be added to the group; obtaining a confirmation result from the client, and adding to the group the user who agrees to be added to the group. By utilizing the method and the system, unwanted disturbance caused by group management in a group communication system is lessened, meanwhile security of a group communication system is improved, and illegal spread of media which is harmful to individuals and society caused by flaws of a group system may be prevented.

Claims

1. A method for adding a group member, comprising:

receiving a request message for adding a group member from a PoC client, the request message including the PoC group information and information of a user to be possibly added to the PoC group;

obtaining the information of the user to be possibly added to the PoC group from the request message, and sending a confirmation message for confirming whether the user agrees to be added to the group to the client corresponding to the user to be possibly added to the PoC group;

obtaining the confirmation response information indicating agreeing to be added to the group;

adding the user corresponding to the confirmation response information to the group according to the group information in the request message.

2. The method of claim 1, wherein the information of the users to be possibly added to the PoC group is a list of the users to be possibly added to the PoC group or a name of a sub-list of the users to be possibly added to the PoC group.

3. The method of claim 2, wherein, obtaining the information of the user to be possibly added to the PoC group from the request message comprises

obtaining the information of the user to be possibly added to the PoC group according to the list of the users to be possibly added to the PoC group.

4. The method of claim 1, wherein, the group information is a group ID;

obtaining the information of the user to be possibly added to the PoC group from the request message comprises;

or,

setting the status identifier of the user corresponding to the confirmation response message as active.

6. The method of claim 2, wherein, adding the user corresponding to the confirmation response message to the group according to the group information in the request message comprises:

preserving the information of the user corresponding to the confirmation response message in a group description file;

or,

setting the status identifier of the user corresponding to the confirmation response message as active.

7. An application server, comprising:

a member information obtaining module, receiving a request message sent from a client, obtaining a group ID in the request message, and obtaining information of users to be possibly added to the group from a group management server according to the group ID;

a notification message sending module, sending a user to be possibly added to the group a notification message to confirm whether the user agrees to be added to the group according to the obtained information of the users to be possibly added to the group.

8. An application server, comprising:

a group change notification subscribing module, subscribing to a group change notification from a group management server;

a group change notification receiving module, receiving the group change notification sent from the group management server, the group change notification comprising information of users whom a client intends to add to a group;

a notification message sending module, sending the user whom the client intends to add to the group a notification message for confirming whether the user agrees to be added to the group.

a group member management module, obtaining the confirmation response information indicating agreeing to be added to the group, adding the user corresponding to the confirmation response information to the group according to the group information in the request message.

10. The group management server of claim 9, further comprising:

a group and group description file creating module, creating a group and generate a group description file according to the request message.

11. A communication system, comprising:

an application server, receiving a request message sent from a client, obtaining a group ID in the request message, and obtaining information of users to be possibly added to the group from a group management server according to the group ID, sending a user to be possibly added to the group a notification message to confirm whether the user agrees to be added to the group according to the obtained information of the users to be possibly added to the group;
