Abstract

The invention provides a down-link quality test method, equipment and system based on grouped user terminals. The method comprises the steps as follows: a down-link detecting parameter is issued to a grouped user terminal of a first group by a base station, and comprises a first evaluation period and a first triggering threshold of a GTCH (grouping traffic channel), as well as a second evaluation period and a second triggering threshold of a GCCH ( grouping control channel); according to the number of grouped user terminals reporting failure information of the wireless down-link in the first group, as well as the total number of the grouped user terminals in a preset time range, the base station obtains a trigger reporting proportion and determines whether the proportion satisfies the preset configuration threshold, and if yes, wireless down-link resources of the first group is configured again. According to the down-link quality test method, equipment and system based on the grouped user terminals, the reasonability and effectiveness of down-link resource configuration of the grouped user terminals are improved, and the down-link communication quality of the grouped user terminals are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a downlink quality detection method, device and system based on group user terminals. Background technique [0002] Long Term Evolution (LTE) of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is referred to as TD-LTE. As a representative of broadband digital communication system, TD-LTE has high bandwidth utilization efficiency , high service bearing efficiency, etc., so the TD-LTE-based digital trunking communication system has become a new direction for the development of digital trunking. [0003] All user terminals under each group service in the digital trunking communication system (referred to as group user terminals) share the same set of downlink configurations. Since group user terminals have mobility requirements and may be located in various locations in the cell, some The group user terminal judges and learns ...
