Group communication method and device

Abstract

The invention discloses a group communication method and device. The method comprises the following steps of: receiving a group access request for accessing a group from a network application, wherein the group access request comprises a group identifier of the group; acquiring the group member information of each group member in the group according to the group identifier; determining first group members connected with a service functional entity through the same gateway according to the group member information; and transmitting a first group member access request for accessing the first group members to the gateway. The device comprises the service functional entity and the gateway, wherein the service functional entity comprises a first receiving module, an acquiring module, a first determining module and a first transmitting module. Due to the adoption of the method and the service functional entity, signaling overhead during group communication can be reduced and the efficiency of group communication is increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a group communication method and a group communication device in the communication field. Background technique [0002] M2M is the abbreviation of "machine to machine (Machine to Machine) communication" or "man to machine (Man to Machine) communication", which mainly refers to the transmission of information through "communication network", so as to realize the data exchange of machine to machine or man to machine , That is to realize the interconnection and intercommunication between machines through the communication network. Due to the particularity of the network, the mobile communication network does not require manual wiring on the terminal side, can provide mobility support, is beneficial to save costs, and can meet the communication needs in dangerous environments, so that the M2M service carried by the mobile communication network can be obtained. It has attracted extensive at...

Problems solved by technology

However, in this group communication, the number of group members may be very large, so if the M2M platform sends a request to each group member separately, then this will cause a large signaling overhead, thereby affecting the quality of group communication. efficiency

For example, if the power company application needs to collect the power consumption of thousands of users in several communities, the power company platform needs to send a separate power consumption report request to each user after receiving the request from the power company application, and Receive a response to the request sent by each user, resulting in a large overhead
