Method for optimizing indication information of control unit in B-TrunC system and equipment

Abstract

The invention discloses a method for optimizing indication information of a control unit in a B-TrunC system. The method comprises the steps that: an indication information bit is set in a reserved bit of a G-RNTI R2 MAC CE, wherein the indication information bit is used for indicating whether a terminal currently takes effect of group GAP parameter configuration or not; when the terminal currently takes effect of group GAP parameter configuration, the terminal sets the position of the indication information to be 1; when the terminal does not take effect on group GAP parameter configuration at present, the terminal sets the position of the indication information to be 0; and the terminal sends the G-RNTI R2 MAC CE to a base station. Corresponding to the method, the invention further discloses terminal equipment. By applying the method and the the terminal equipment disclosed by the invention, the problem of inconsistent GAP parameter configuration on the base station side and the terminal side can be avoided.

Description

technical field [0001] The present application relates to the technical field of trunking communication, and in particular, to a method and device for optimizing indication information of a control unit in a B-TrunC system. Background technique [0002] The Broadband Trunking Communication System (B-TrunC) TS 02.004 protocol is described as follows: [0003] The length of the group call wireless network temporary identification medium access control layer control element (G-RNTI R2 MAC CE) is 24 bits, and the format is as follows figure 1 shown, where: [0004] bit0: When the value is "0", it indicates that the terminal is a blind detection capability type 1 terminal, and when the value is "1", it indicates that the terminal is a blind detection capability type 2 terminal; [0005] bit1: When the value is "0", it means exiting the group call corresponding to the G-RNTI, and when the value is "1", it means joining the group call corresponding to the G-RNTI; [0006] R: Set...

AI Technical Summary

Problems solved by technology

[0015] Due to the unreliability of MAC CE air interface transmission, it is difficult for the base station to judge whether the currently received G-RNTI R2 MAC CE represents the GAP parameter of the effective group, that is to say: the base station cannot distinguish the currently received G-RNTI R2 MAC CE It means that the terminal joins the group, or it means the GAP parameter of the effective group

[0016] The main reason for the above problems is that the protocol definition does not distinguish between the above two scenarios

The existence of the above problems may easily lead to inconsistencies in the GAP parameter configurations that take effect on the base station side and the terminal side, thus affecting business operations.
