Abstract

In the TD-SCDMA system, there is a problem that non-emergency voice services probability of dropped call is not ideal when we use the dynamic allocation algorithm. To solve this problem, we propose a new algorithm, which is called protect channel reservation queue movable boundary dynamic channel allocation. This algorithm set aside channels for dropped calls of non-emergency voice services service, in order to keep blocking probability for service, the introduction of no patient customers, combined with the data packet to borrow algorithms. Simulation results show that, comparing to the movable boundary algorithm, the proposed algorithm reduce the drop probability for non-emergency voice services, and maintain a variety of service blocking probability, reducing the packet loss probability data services.
