Terminal cluster registration method, device, system and core network equipment

Abstract

The present invention discloses a terminal trunking registration method, a terminal trunking registration device, a terminal trunking registration system and a core network device. The terminal trunking registration method includes the following steps that: a mobile management entity responds to a standard LTE movement flow executed by a terminal, a trunking registration context of the terminal is requested from a mobile management entity where the terminal is located before the movement of the terminal; the location information of the terminal and the trunking registration context are added to a trunking registration message, so that a trunking registration message carrying the location information of the terminal and the trunking registration context can be obtained; and the trunking registration message is sent to a trunking control function, so that the mobile management entity can act as an agent of the terminal so as to perform trunking registration at the trunking control function. The terminal trunking registration device, the terminal trunking registration system and the core network device are matched with the terminal trunking registration method. With the terminal trunking registration method, device, system and the core network device of the invention adopted, after the terminal moves through different mobile management entities, the corresponding mobile management entity can act as the agent of the terminal so as to perform trunking registration, and therefore, the problem of reliance on the active triggering of a terminal in the prior art in the prior art can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal cluster registration method, device, system and core network equipment. Background technique [0002] In the digital trunking communication system, in order to perform the trunking service, the terminal needs to complete the trunking registration in addition to the network registration. The flow of the network registration and the trunking registration is briefly described below. [0003] When the terminal is powered on, it first initiates the boot attachment process, performs network registration, and establishes a default bearer. After the default bearer is established, the terminal initiates the trunking registration process to the mobile management entity (MME, Mobile Management Entity), and the mobile management entity sends a trunking registration message to the trunking control function (TCF, Trunking Control Function) to complete the trunking reg...

AI Technical Summary

Problems solved by technology

[0004] After the terminal performs cluster registration, if it moves to another mobility management entity without performing cluster services, the previously registered cluster control function body will not know where the terminal is after moving, and the mobility management entity where the terminal is after moving will also not know. The terminal has already registered with the cluster before, so the terminal cannot directly perform the cluster business. Therefore, the terminal needs to initiate the cluster registration process again to facilitate the development of the subsequent cluster business.
