Problems solved by technology

[0016] In view of this, the main purpose of the present invention is to provide a method for indicating the available channels for sending uplink access requests. This method can not only instruct users in the trunking group to use idle uplink channels on the trunking system network side that supports the 1.0 channel implementation method. The channel sends the uplink access request, and it can solve the problem that the listener cannot pass the call when the speaking party is first assigned an uplink group call channel and then reassigns a dedicated uplink channel to speak in the 1.5 channel implementation method on the trunking system network side. The uplink group call channel occupied by the party initiates an uplink access request

Embodiment Construction

[0038] 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.

[0039] 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 for prompting a usable channel for sending an uplink aceessing request, the method comprises that, a trunking communication network sends an usable channel busy message or a voice group-calling service additional information message with a prompting message in a trunking group cell, the prompting message carries a message for prompting whether an uplink group-calling channel of a trunking group is usable; a receiver in the cell of the trunking group determines whether the uplink group-calling channel is usable based on the received uplink busy message or the information carried in the prompting message of the voice group-calling service additional information message, if it is, the uplink accessing request is sent via the uplink group-calling channel; otherwise, the uplink accessing request is sent via a random accessing channel.

Description

technical field [0001] The invention relates to the technique of seizing an uplink channel for speaking in a trunking wireless communication system, and particularly relates to a method for indicating an available channel for sending an uplink access request. Background technique [0002] 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 mining enterprises, fire police, water conservancy and The military and other units are used to meet the needs of internal communication of each unit. [0003] The most basic service provided by the trunking system is the Voice Group Call Service (VGCS). VGCS allows a user to establish a call with multiple users within a group group with the same group identification (ID) belonging to a given service area con...
