A communication method and server based on group communication support system gcse

Abstract

The embodiment of the present invention discloses a communication method based on the group communication support system GCSE, which is applied to the communication system based on the GCSE; the communication system based on the GCSE includes: an industry application server, at least one GCSE application server, and each GCSE application server communicates with the Industry application server connection; wherein, the method includes: the industry application server receives the contact information acquisition request sent by the target GCSE application server; the industry application server obtains the contact information of the second terminal corresponding to the request identification according to the request identification; The target GCSE application server sends the contact information of the second terminal. The embodiment of the invention also discloses an industry application server and a GCSE application server.

Description

technical field [0001] The invention relates to the technical field of private network communication, in particular to a communication method and server based on a group communication support system GCSE. Background technique [0002] At present, private network communication has been widely used in various industries due to its network independence and security. With the continuous development of communication technology, the Group Communication System Enabler (GCSE) used in private network communication has gradually Accepted by public network users. [0003] GCSE is proposed by the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), figure 1 It is a schematic diagram of the structure based on GCSE in the prior art, such as figure 1 As shown, the GCSE includes: user equipment (UE, User Equipment), base station (eNB, Evolved Node B), packet core network (EPC, Evolved Packet Core) and GCSE application server (GCSE AS, GCSE Application Server), wh...

Problems solved by technology

[0004] However, based on the structure of GCSE, although the separation of network bearing applications in the same industry has been initially realized, with the gradual improvement of the network protocol (IP, Internet Protocol) of the bearing network, the continuous interconnection and intercommunication between various networks and the private network communication With the continuous diversification of industry applications, the functions of GCSE AS are gradually increasing, and the corresponding maintenance and management costs are gradually increasing. With the continuous increase of industry applications, it is inevitable that the bearer network will be coupled with the same industry applications, which is not conducive to the bearer network. Upgrading and subsequent expansion of industry applications

In this way, the existing GCSE-based private network communication technology has the defect of mutual coupling between the bearer network and industry applications, resulting in poor scalability and maintainability of the system
