Problems solved by technology

However, since the current 1.5 channel implementation methods all use the uplink group call channel allocated when the group call is established to send the uplink access request, unlike the 1.0 channel implementation method, the uplink group call channel is sent through the downlink channel. When the user sends an uplink access request to the two implementation methods that support both, the following problems occur
Problem 1: The user cannot know which implementation method is currently adopted by the network side of the trunking system, so when the message that the uplink group call channel is i

Embodiment Construction

[0032]In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0033] When the trunking system network side supports the 1.5 channel implementation method and / or the 1.0 channel implementation method, regardless of whether the trunking system network side is currently using the 1.5 channel implementation method or the 1.0 channel implementation method, the user in the trunking group sends an uplink access request The uplink channel can only be the uplink group call channel allocated when the group call is set up or the RACH in the trunking group. Therefore, the method provided by the present invention can uniformly use the downlink channel to send an indication message to indicate which uplink channel the users in the trunking group can use to send uplink access regardless of the channel implementation ...

Abstract

The invention discloses a method and a system for indicating an available channel for sending an uplink access request. The method comprises the following steps that: a cluster system network side sends an uplink busy message or a voice group call service (VGCS) additional information message in which an indication message is set in a cell of a cluster group, wherein the indication message carries information indicating a channel for sending the uplink access request; and an answering party in the cell of the cluster group sends an uplink access request on an uplink group call channel or a random access channel indicated by the information according to the information carried by the indication message set in the uplink busy message or the VGCS additional information message.

Description

[0001] This application was submitted to the Chinese Patent Office in April 2006, the application number is 200610073012.2, the application date is April 10, 2006, and the invention title is "a method and system for indicating available channels for sending uplink access requests" A divisional application of the application, the entire contents of which are incorporated into this application by reference. technical field [0002] The present invention relates to the technique of preempting uplink channel for speaking in trunking wireless communication system, in particular to a method and system for instructing available channel for sending uplink access request. Background technique [0003] Trunking wireless communication system, hereinafter referred to as trunking system, is a relatively economical and flexible command and dispatch communication system developed in recent years, widely used in government agencies, energy transportation, airport terminals, industrial and mi...
