Problems solved by technology

In this way, since each protocol entity will perform a large number of unnecessary user traversals, it will lead to a large group establishment time overhead and a waste of server computing resources, especially when the group size is large, these problems are more prominent, such as When the number of group users reaches the order of thousands, the group creation time may exceed several seconds, which seriously affects the user experience

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] figure 1 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 1 As shown, the method for establishing a group call implemented in this embodiment mainly includes:

[0033] Step 101, the session initiation protocol (SIP) server uses the group entity to maintain the user status of all member users in each group in real time.

[0034] This step is used for a group entity to maintain the status of member users in each group in real time, so that when the SIP server requests to receive a group session establishment request, the group entity can update the group users based on the user status information Further division, and each group sub-entity establishes a corresponding group user...

Abstract

The invention discloses a method and device for establishing a group call. The method comprises the steps that a session initiation protocol (SIP) server maintains user states of all member users in each group in real time by using a group entity; when the SIP server receives a session establishment request of the group, the group entity groups the users in the corresponding group according to theuser type and the user state and a preset grouping type; and for each group of users except the unregistered users, the group entity sends a list of the group of users to a group sub-entity matched with a protocol used by the group of users, and triggers the group sub-entity to establish a corresponding group user session according to the received list. By adopting the method, the group creationefficiency can be effectively improved, and the resource overhead is reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for establishing a group call. Background technique [0002] The Session Initiation Protocol (Session Initiation Protocol, SIP) protocol is a multimedia communication protocol developed by the Internet Engineering Task Force (Internet Engineering Task Force, IETF). It is a text-based application-layer control protocol for creating, modifying, and releasing sessions between participants. In addition to point-to-point calls, there are relatively complex SIP applications, such as group calls, where one person speaks and others listen. If a listener wants to speak, he can also seize the right, and the SIP server will judge whether to authorize according to the established strategy. [0003] In practical applications, a group may include different users, such as dispatcher users, unicast users following the 3GPP protocol, multicast users following the 3GPP proto...
