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 framework. 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 defined i...

Abstract

The invention discloses a cluster communication method, device and system. In the present invention, the multipoint service function entity receives the group call establishment request sent by the trunking control server; the multipoint service function entity initiates the group paging process through the mobility management entity to trigger the group call establishment request according to the received group call establishment request. Establishment of the multicast bearer: the multipoint service function entity returns a group call establishment response to the cluster control server after the establishment of the multicast bearer is completed. The EPC-based group communication service can be realized by adopting the invention.

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 network support group communication based on LTE (LongTerm Evolution, Long Term Evolution). 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 comma...
