The group user terminal of first group is after obtaining the down link detected parameters that the base station issues, detect according to the down link detected parameters, be specially: the group user terminal is obtained the down link quality of reception of group service channel in first assessment cycle when first assessment cycle arrived, and judges whether the down link quality of reception of group service channel in first assessment cycle satisfies first and trigger thresholding; And when second assessment cycle arrived, obtain the down link quality of reception of group's control channel in second assessment cycle, and judge whether the down link quality of reception of group service channel in second assessment cycle satisfies second and trigger thresholding.If the group user terminal judges knows that the down link quality of reception of group service channel in first assessment cycle satisfies first and trigger thresholding, then send the down wireless link failed message to the base station; Perhaps, the down link quality of reception of group's control channel in second assessment cycle satisfies second and triggers thresholding, then send the down wireless link failed message to the base station, thereby the base station receives the down wireless link failed message that the group user terminal sends.
Set in advance the processing time of down-chain resource configuration in the base station, when arriving the processing time, the base station reports the quantity of the group user terminal of down wireless link failed message in this first group in the Preset Time section according to the group identification statistics, and the total quantity of all group user terminals in this first group, and determine to trigger the ratio that reports according to the ratio of the total quantity of the quantity of the group user terminal that reports the down wireless link failed message and group user terminal, thereby report ratio and the configured threshold of presetting to compare triggering, judging to trigger reports ratio whether to satisfy default configured threshold, know that triggering reports ratio to satisfy configured threshold if judge, then the base station is this first group configurating downlink air-link resources again, to improve the communication quality of the down wireless link of group user terminal in first group, guarantee the group service reliability of data transmission.
The downlink quality detection method based on the group user terminal that present embodiment provides, issue the down link detected parameters by the base station to the group user terminal of first group, the group user terminal is obtained the down link quality of reception of group service channel and group's control channel according to the down link detected parameters, know that the down link quality of reception satisfies the triggering thresholding if judge, then report the down wireless link failed message to the base station, the base station is informed in the satisfied default configured threshold of ratio that the group user terminal that reports the down wireless link failed message in the Preset Time section in this first group accounts for the total quantity of group user terminal if judge, reconfigure the down wireless link resource, improved reasonability and the validity of base station to the configuration of group user terminal downlink resource, thereby improved the downlink communication quality of group user terminal, guaranteed the group service reliability of data transmission.

9. a group user terminal is characterized in that, comprising:
Second receiver module is used for receiving the down link detected parameters that the base station issues, and described down link detected parameters comprises first assessment cycle of group service channel and second assessment cycle and the second triggering thresholding of the first triggering thresholding and group's control channel;
Acquisition module is used for obtaining the down link quality of reception and described group control channel the down link quality of reception during described second assessment cycle of described group service channel in described first assessment cycle;
Second judge module is used for judging whether the down link quality of reception in described first assessment cycle satisfies the described first down link quality of reception that triggers in thresholding and described second assessment cycle and whether satisfy the described second triggering thresholding;
Second sending module, be used for if judge that the down link quality of reception of knowing in described first assessment cycle satisfies described first and triggers thresholding, or the down link quality of reception in described second assessment cycle satisfies the described second triggering thresholding, then send the down wireless link failed message to described base station, so that described base station determines whether to reconfigure the down wireless link resource according to described down wireless link failed message.
10. group user terminal according to claim 9 is characterized in that, described first triggers thresholding and described second triggers the triggering thresholding that thresholding comprises at least one the channel transmission parameters correspondence in the error rate, bit error rate, Block Error Rate and the frame error rate;
Described acquisition module specifically is used for: obtain described group service channel and trigger at least one corresponding channel transmission parameters of thresholding with described first in described first assessment cycle, and obtain described group control channel and trigger at least one corresponding channel transmission parameters of thresholding with described second in described second assessment cycle.
11. the downlink quality detection system based on the group user terminal is characterized in that, comprises as claim 7 or 8 described base stations, and as claim 9 or 10 described group user terminals.
