Abstract
In the TD-SCDMA trunking communication system, users need to have predefined priority in the trunking group, according to the users priority access the uplink traffic channel, the users with the high priority give priority to make use of these channels. To solve these problems, we proposed one random access algorithm based on priority to maximize the access success rate and provide the high priority users with better QoS (Quality of Service). For further discussion, three kinds of algorithms were given to divide the priorities in this article. Each algorithm was simulated and its applicable situation was analyzed.
Supported by National Science & Technology Major Program (2012ZX03004009), the special fund of Chongqing key laboratory (CSTC) and the transformation project of excellent achievement of Chongqing Municipal Education Commission (Kjzh11206).
