Problems solved by technology

However, when multiple message processes are executed between the core network and the base station, multiple messages need to be exchanged between the core network and the base station, which will lead to the problem of increasing the processing delay or processing complexity of the signaling plane
Specifically, if serial processing of messages is used between the core network and the base station, the processing delay of the signaling plane will be increased; if parallel processing of messages is used between the core network and the base station, the cross-flow processing of the two network elements will be increased respectively. the complexity

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The core idea of ​​the present invention is to add information elements in the group call context modification message to carry the TE-RAB change information, so that the group call context modification message can meet the requirements of network elements in the scenario where TE-RAB and GroupCallArea change simultaneously. The need for information interaction does not need to trigger the establishment or modification process of the group call bearer, so that the service establishment delay can be reduced, and the processing complexity caused by the cross process between network elements can be avoided.

Abstract

The invention discloses a group call information changing method, device and system of a wireless broadband cluster. The method comprises the following steps: when the newly added evolved UTRAN cluster radio access bearer (TE-RAB) and the group call area (GroupCallArea) are changed at the same time, the core network informing the base station of the change information of the corresponding TE-RAB and GroupCallArea by using the group call context modification message; and the base station updating the TE-RAB and the GroupCallArea of the corresponding group call according to the group call context modification message. By adopting the invention, the processing complexity caused by the service establishment delay and the cross flow between the network elements can be reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method, device and system for changing group call information of a wireless broadband cluster. Background technique [0002] In some business scenarios of wireless broadband trunking, such as emergency group calls, it may happen that the group call area (GroupCallArea) changes while the newly added evolved UTRAN trunking radio access bearer (TE-RAB) changes , specifically the following scenarios: [0003] When the new cluster bears TE-RAB, the GroupCallArea changes; [0004] When the cluster bears TE-RAB, the GroupCallArea is changed; [0005] When the cluster bearing TE-RAB is deleted, the GroupCallArea is changed. [0006] Under the current system protocol, as shown in the following table, in the B-TrunC trunking protocol, the group call context modification message can only modify AMBR and GroupCallArea cells, but cannot add or modify TE-RAB. [0007] [0008] In thi...
