Abstract

The present invention provides a method, device and system for improving the voice quality of a private network. A centralized scheduler is used to obtain a list of semi-static activated subframes of the cluster voice of each cell in a cluster, and the video of each cell is obtained according to the list of semi-static activated subframes of the voice of the cluster. The schedulable subframe list is then sent to the base station of the corresponding cell, so that the base station performs video service scheduling in the cell according to the video schedulable subframe list. The centralized scheduler performs interference coordination for all base stations in the cluster, and the base station only performs video services in the cell within each video schedulable subframe in the video schedulable subframe list, so that any cell in the cluster is performing the cluster voice service. It will not be interfered by the same frequency caused by the scheduling of video services in adjacent areas, avoid the loss of words in the trunking voice, improve the quality of trunking voice services, and improve the system performance.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, device and system for improving voice quality of a private network. Background technique [0002] With the development of public network service and multimedia communication technology, trunking communication has been widely used. The current trunking system can not only perform trunked voice calls, but also data services such as video calls and video distribution. [0003] Under the condition of co-frequency networking, when a cell is performing trunked voice services, if adjacent cells are performing video services, co-channel interference will occur, resulting in lost words in the trunking voice of the cell, affecting the quality of trunked voice calls. SUMMARY OF THE INVENTION [0004] The present invention provides a method, device and system for improving the voice quality of a private network, so as to perform interference scheduling, so ...
