Example Embodiment

[0031] Such as figure 1 As shown, an embodiment of a method for updating call information of a trunking communication system terminal includes the following steps:

[0032] Step 1. After the terminal enters the cell, if the terminal is not in a talking state, perform steps 2-5;

[0033] Step 2. The terminal decodes the message of the BCCH channel, obtains system message 1, and obtains the configuration parameters of the NCH channel from the system message 1, and starts NCH channel monitoring according to the configuration parameters;

[0034] Step 3. If a group call / broadcast is established, the terminal monitors the group call / broadcast notification message sent by the network on the NCH channel, and saves the group call / broadcast group call / broadcast information in the terminal;

[0035] Step 4. If the group call / broadcast information is changed, the terminal monitors the group call / broadcast notification message sent by the network on the NCH channel, and compares and updates the gr...

Abstract

The invention discloses a call information updating method for a trunking communication system terminal. The method comprises the following steps that: after entering a cell, a terminal executes the subsequent steps if not in a call state; the terminal decodes a message of a broadcast control channel (BCCH) to obtain a system message 1, obtains configuration parameters of a notification channel (NCH) from the system message 1, and starts NCH listening according to the configuration parameters; if a group call/broadcast is established, the terminal saves the information of the group call/broadcast at the terminal after listening to a group call/broadcast notification message transmitted in the NCH by a network; if the information of the group call/broadcast is changed, the terminal compares and updates the information of the group call/broadcast saved at the terminal after listening the group call/broadcast notification message transmitted in the NCH by the network; and the terminal displays the information of the group call/broadcast in real time, wherein the information comprises information on group number and information on whether the group call/broadcast is initiated by the terminal or not.

Description

technical field [0001] The invention relates to a method for updating call information of a cluster communication system terminal. Background technique [0002] Group call / broadcast service is an important service of the trunking communication system. It breaks through the limitations of point-to-point communication. It can establish group calls in a simple way, realize specific functions such as dispatching command and emergency notification, and is especially suitable for railway traffic command and dispatch. department. [0003] Voice Group Call Service (VGCS) is a telecommunication service. The group call service defines a point-to-multipoint voice communication mode in which multiple parties participate (mobile stations or fixed-line telephones), some of whom can speak, and multiple parties listen. The voice group call service can call all members of the group with one group function code (group ID), and the mobile users participating in the same voice group call serv...
