Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiment:

[0019] Group calls and private calls are important service features in the trunking system. A group call means that a single user can talk to all the people in the group at the same time when allowed. Except for the person who is speaking, other users in the group must listen, and once a user in the group presses the PTT button, if the priority of other users is the same as that of the person who is speaking, they cannot intercept and can only wait to speak people to complete the call. A private call is a one-to-one user call. In a group, you can also choose the person you want to talk to and make a call without being heard by other members of the group. The CDMA trunking communication system adopts fast group call and private call connection. For the trunking group call service, a packet data channel is used, that is, the establishment of a fast call is realized by means o...

Abstract

The invention discloses a method for quickly establishing a call of a CDMA trunking communication system in the field of mobile communication. Firstly, the system is initialized; The user terminal initiates a group call; the base station uses the pre-stored default parameters to establish service information without negotiating with the terminal, and sends the call-initiating user terminal message to the group scheduling server through the public group message channel; the group The scheduling server initiates a trunking service establishment request to other user terminals in the group through the public trunking message channel; the base station uses the saved parameter information to directly establish a service channel for other user terminals in the group; finally enters the trunking call state. The invention overcomes the defect that the connection time of the existing CDMA system is long and cannot meet the needs of cluster services, realizes the always-online of users, and saves the connection time of cluster users.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for quickly establishing a call in a trunking mobile communication system of the CDMA system. Background technique [0002] The trunking communication system refers to a dedicated mobile communication system in which multiple users share a group of wireless channels and dynamically use these channels. It is a command and dispatch system. It is widely used in enterprises, institutions, industrial and mining, oil fields, farms, public security, police and military departments with high command and dispatch functions. [0003] The main feature of the trunking communication system of the CDMA standard is that it adopts a half-duplex communication mode, which can realize fast connection, and supports group calls (that is, one-to-many call mode). In the trunking communication system, the users in the group are required to share the forward channel in the same cell. When the gr...
