Problems solved by technology

[0005] In view of this, the purpose of the present invention is to provide a method for quickly establishing a call in a TD-SCDMA trunking communication system, utilizing the characteristics of the air interface structure of TD-SCDMA, and adopting dynamic allocation and competition to solve the problem of UE quickly establishing a call. The method of quick call establishment is different from that of ordinary business, and also different from the method of quick call establishment in the two aforementioned modes

Embodiment Construction

[0041] In TD-SCDMA, except for the Uu interface, the UE is always online on other interfaces. For the Uu interface, at the initial stage of establishing a group call, regardless of whether there is a UE in the cell, the air interface resources are used to allocate the corresponding group call in each legal cell. Group call service channel, which is a pair of uplink and downlink channels. When the cell has UEs entering the trunking service, the UE access information is reported in a competitive manner. If the network side does not receive the UE's reported access information (that is, feedback response information) within the specified time, it is considered that a certain cell has no UE. , if there is no UE in this cell, delete the corresponding uplink and downlink channels.

[0042] The method for quickly establishing a group call of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

This invention relates to a quick setting-up method for calls of a TD-SCDMA cluster communication system applying a mode of dynamic distribution and competition, in which, the network side sets up multi-call service channels for all legal local areas and initiates a multi-call broadcast message at the beginning of initiating multi-call, a called UE decides if it sends a feedback response message according to its grade and if the network side needs feeding back a message, and the multi-call service channels and empty resources of the un-activated regions will be released.

Description

technical field [0001] The present invention relates to a method for quickly establishing a call in a trunked communication system based on the 3rd generation (3G) mobile communication system, and in particular to Time Division-Synchronous Code Division Multiple Access (hereinafter referred to as TD -Call fast establishment method of SCDMA) trunking communication system. Background technique [0002] At present, the main domestic systems include the Global Open Trunking Architecture (hereinafter referred to as GOTA) system based on Code Division Multiple Access 2000 (hereinafter referred to as CDMA 2000), and the Global System for Mobile Communications (Global System for Mobile Communications) based system. System for Mobile Communication) (hereinafter referred to as GSM) GT800 technology, for the trunking system, one of the core technologies is the rapid call establishment of the user terminal, and the solution for the rapid call establishment is related to the access metho...
