Description

Group communication transmission method, device and device

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a method, an apparatus, and a device for transmitting a group communication.

Background technique

The Mission Critical Service (MCS) includes the Mission Critical Push To Talk (MCPTT) service, the MCVideo service, and the MCData service.

In the prior art, the MCPTT service has two group communication scenarios: a single MCPTT system group call and a multiple MCPTT system group call. In the scenario of a single MCPTT system group call, the MCPTT servers (Primary MCPTT servers) of all group users are the same and are the same MCPTT server as the group MCPTT server (Group home MCPTT server); in the multiple MCPTT system group call scenario, The Primary MCPTT server and the Group home MCPTT server are different MCPTT servers, that is, the group call members are distributed under different MCPTT servers.

The MCPTT service can use the Multimedia Broadcast and Multicast Service (MBMS) bearer mode for group call communication, or the unicast bearer mode for group call communication. Whether it is a single MCPTT system group call or a multiple MCPTT system group call, the MCPTT server needs to determine the transmission mode of the MCPTT service according to the location information of the user.

At present, the method for obtaining the location information of the user defined in the MCPTT system is as follows: The Primary MCPTT server sends configuration information including the trigger condition to the MCPTT client, and the MCPTT client determines the location of the user when the current situation meets the trigger condition. The information is reported to the Primary MCPTT server; or the Primary MCPTT server sends a location information request to the MCPTT client, and when the MCPTT client receives the location information request, the location information of the user is sent to the Primary MCPTT server. Similarly, the method is equally applicable to the MCVideo service, the MCData service, and the like.

However, in a multi-system scenario, for a particular group, the group members are partially owned by the group. The home MCPTT system is partially owned by other MCPTT systems. Before the group call is initiated, the Group home MCPTT server can obtain the location information of the group users belonging to the Group home MCPTT server through the existing method, but cannot obtain the group belonging to other MCPTT servers. Group user location information. Therefore, when the group call is initiated, the Group home MCPTT cannot determine whether to use the MBMS bearer service according to the location information of all users in the group.

Step 201: The first server acquires location information of the user in the group from the second server according to the group information. The group information includes an identifier of the group and/or a user identifier of the user in the group.

In this embodiment, one group corresponds to the identifier of one group, and each user in the group corresponds to one user identifier, and the user identifier of the user in the group may be recorded in the form of a list. The first server may obtain the location information of the user in the group from the second server according to the group information in different manners. For example, when the user in the group initiates the group communication, the first server sends the group information to the second server. The server returns the location information of the user in the group to the first server by the second server; or the second server actively reports the location information of the user in the group to the first server at each preset time interval. Or, in the group communication service, when the location information of the user in the group is updated, the second server reports the updated user location information and the like to the first server. Moreover, when the types of the second servers are different, the method for the first server to obtain the location information of the users in the group from the second server according to the group information is different, and those skilled in the art may select an appropriate method to obtain the group according to actual conditions.

When it exceeds 10, the MBMS bearer service is adopted.

It should be noted that using the MBMS bearer service includes establishing, modifying, and deleting the MBMS bearer service. For example, if the group does not have an established MBMS bearer service, the MBMS bearer service needs to be established. If the group has an established MBMS bearer service, the established MBMS bearer service may be established according to the location information of the user in the group. The modification is performed. When the MBMS bearer service is no longer used by the group, the MBMS bearer service may also be deleted.
