Embodiment Construction

[0023] The LTE network needs to provide services such as mobility management, connection and bearer establishment, modification, and release for the trunking communication system. The cluster business belongs to the category of the application layer and is transparent to the top-layer network. Therefore, in order to effectively utilize the resources of the LTE network, the LTE network should provide the cluster application with a necessary interface, so that the bearer can be established and managed according to the requirements of the cluster application.

[0024] Based on the above requirements of 3GPP, the embodiment of the present invention proposes a solution for establishing a group call service by enhancing the EPC architecture. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 , is a schematic diagram of the interface between the EPC network and the cluster control server define...

Abstract

The invention discloses a trunking communication method, a device and a system. According to the method, a multi-point service function entity receives a group call establishing request sent by a trunking control server; according to the received group call establishing request, the multi-point service function entity initiates a group call process through a mobile management entity to trigger establishment of multicast bearing; after accomplishing establishment of multicast bearing, the multi-point service function entity returns a group call establishment response to the trunking control server. Through the method, group communication business based on EPC can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a trunking communication method, device and system. Background technique [0002] The main application scenario of cluster communication is to meet the needs of public safety communication and emergency communication. At present, 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) is studying the support of group communication based on LTE (Long Term Evolution, long-term evolution) network The problem is mainly to study how to enable LTE network to efficiently support trunking communication services, such as voice group calls, video group calls, etc., so that trunking communication applications can use the system functions provided by 3GPP networks to establish communication services. [0003] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the co...
