Problems solved by technology

[0004] B-TrunC redefines the reserved field of LTE. This field is only 1 bit, and this reserved field is still 1 bit in 5G. There is a risk of conflict with B-TrunC due to 3GPP using this field during protocol evolution.
Therefore, in 5G communications, if this risk is not avoided in time, the losses caused are difficult to estimate

Abstract

The embodiment of the invention discloses a cluster service implementation method and device, a medium, a base station and a system. The method is executed by a base station, and comprises the following steps: establishing network interface connection with a cluster core network, and acquiring a network slice identifier of the cluster core network; responding to a connection request of terminal equipment, and determining a target identifier in request information of the connection request; determining a target network interface according to the target identifier; and sending the NAS message ofthe terminal equipment to a cluster core network through the target network interface so as to establish signaling connection related to the terminal and perform authentication and cluster service. By adopting the technical scheme provided by the invention, the corresponding cluster core network can be distinguished on one side of the base station according to the predefined slice identificationinformation of the cluster, so that the risk of air interface protocol conflict in 5G communication is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method, device, medium, base station, and system for implementing trunking services. Background technique [0002] With the development of science and technology and the official release of 3GPP R15, 5G communication has officially entered commercial deployment. [0003] At present, the B-TrunC (Broadband Trunking Communication, broadband trunking communication) standard has already started the research work on 5G trunking in the existing technology. Among them, B-TrunC is a TD-LTE-based "LTE digital transmission + trunking voice communication" private network broadband trunking system standard formulated by the Broadband Trunking (B-TrunC) Industry Alliance. [0004] B-TrunC redefines the reserved field of LTE. This field is only 1 bit, and this reserved field is still 1 bit in 5G. There is a risk of conflict with B-TrunC due to 3GPP usin...
