Embodiment Construction
[0034] Embodiments of the present invention provide a PoC group communication method, system, and device. In the method, after the terminal where the first group member is located sends a group session request to the server, it receives each response from the server for accepting the group session request. The information of each second group member, compare the information of each second group member with the saved information of the third group member with session authority, when the third group member rejects the group When the group member of the session request, resend the group session request. Because in the embodiment of the present invention, the terminal where the first group member is located saves the information of the third group member with session authority, and when it is determined that there is a group member who rejects the group session request among the third group members , resend the group conversation request, thereby saving network resources.

The invention discloses a method, a system and a device for PoC (Push-to-talk over Cellular) group communication, which are used for solving the problem of the waste of network resources resulted from the method for the PoC group communication in the prior art. The method comprises the following steps of: after a terminal where a first group member belongs transmits a group session request to a server, receiving the information of each second group member receiving the group session request, wherein the information of each second group member is returned by the server; comparing the information of each second group member with stored information of third group members with session permissions; and when some group members of the third group members reject the group session request, retransmitting the group session request. According to the embodiment of the invention, the information of the third group members with session permissions is stored in the terminal where the first group member belongs to, and the group session request is retransmitted when the condition that some group members of the third group members reject the group session request, is determined, so that the network resources are saved.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and device for Push to Talk over Cellular (PoC) group communication. Background technique [0002] PoC refers to the half-duplex voice service based on the packet domain bearer of the mobile cellular network and realized by using IP-based voice transmission protocol (Voice over Internet Protocol, VoIP) technology. Users can conduct one-to-one conversations with other users through the PoC service platform. , or a one-to-many group conversation. [0003] A talk group can be created. When the first group member in the group initiates a group conversation with the group, the first group member sends a group conversation request to the server, and the server then sends the group conversation request to For all group members in the group, the voice information of the first group member will be sent to each group member who accepts the group conversation ...
