Problems solved by technology

If a group user first receives the FLOOR INFORM message and records the NAS COUNT value of 2, and then receives the GROUP CALL SETUP INDICATION message with the NAS COUNT value of 1, the group user will consider the message as an error message and discard it directly. As a result, users in this group cannot correctly receive multicast group services

Embodiment Construction

[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a signaling processing method for a cluster group according to the present invention, which may specifically include the following steps:

[0028] Step 102, after the trunking group call service is established, periodically send a group call establishment indication message, wherein the group call establishment indication message is used to indicate the access user's trunking group call establishment.

[0029] A UE (User Equipment, user equipment) in an idle (IDLE) state can initiate a group call and execute an RRC connection establishment procedure. The UE carries the NAS message, TRUNKING SERVICE REQUEST (trunk service request) in the connectio...

Abstract

The embodiment of the invention provides a signal processing method and device for a trunking group and is used for ensuring normal performance of trunking group business. The method comprises the steps of periodically sending a group call setup indication message after trunking group call business is set up, wherein the group call setup indication message is used for indicating trunking group call setup of an access user; updating the group call setup indication message according to a business state of the trunking business after a downlink bearer of a base station is set up successfully, thereby indicating the business state of the trunking business through the group call setup indication message; and periodically sending the group call setup indication message, wherein the group call setup indication message is sent after being encrypted. The group call setup indication message indicates the group call setup and also indicates the business state of the trunking business, the normalperformance of the business is ensured, and the user is guaranteed to receive multicast group business accurately.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a signaling processing method for a trunking group and a signaling processing device for a trunking group. Background technique [0002] The private network broadband trunking system based on TD-LTE (Time Division-Long Term Evolution) technology can maximize the basic business needs of different industries and different networking scenarios, and has attracted more and more attention. A feature of the TD-LTE broadband trunking system is to use the trunking shared channel for the cells, thereby saving air interface resources. Among them, the NAS (Non-Access Stratum, non-access stratum) message base station in the trunking TCCH (Trunking Control Channel, trunking control channel) sends periodically, so that users who enter later can quickly obtain the trunking group information configuration and receive it in time cluster business. [0003] Wherein, for a voice call...
