Method and system for implementing pool mechanism of b-trunc group business

Abstract

This application discloses a method and system for implementing the POOL mechanism of B-TrunC group business, including: the group opens accounts in all TCFs, and each group is configured with a TCF with the highest priority; During group registration, the corresponding V-TCF initiates a group control right competition request to all TCFs including the V-TCF, and determines the G-TCF of the group through dynamic competition; the G-TCF The TCF periodically broadcasts heartbeat information to other TCFs, and when the other TCFs do not receive the heartbeat information of the G-TCF over time, the other TCFs delete the group information associated with the G-TCF, and the UE re-initiates the corresponding group business. By applying the technical solution disclosed in this application, multiple core networks can be configured to implement PTTPOOL, thereby expanding the processing specifications of the cluster, and realizing PTT backup based on core network load sharing.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and system for implementing a POOL mechanism of B-TrunC group services. Background technique [0002] In the broadband trunking communication (B-TrunC: Broadband Trunking Communication) standard, a roaming architecture across the core network of the cluster is defined. The architecture supports the unified enhanced home subscriber server (eHSS) architecture mode, which is used in scenarios where there are multiple cluster core networks (TCN) and one public land mobile network (PLMN). The specific architecture of roaming across the cluster core network is as follows: figure 1 shown. [0003] Here are three classifications of the roles of the Cluster Control Function (TCF): [0004] 1) H-TCF: TCF of UE's home (namely: account opening place). [0005] 2) V-TCF: UE visits (ie: access) TCF. [0006] 3) G-TCF: TCF of the place where the group business...

AI Technical Summary

Problems solved by technology

That is, in the case of a certain H-TCF or G-TCF failure, the corresponding group services cannot be automatically migrated to other TCFs

[0017] It can be seen that in the cluster application scenario, for the cluster core network backup scenario, only the 1+1 active / standby mode can be used, and multiple core networks cannot be configured to form a POOL, and the cluster core network backup is implemented using the POOL method
