Abstract:

A multi-services group handover algorithm under constraint of blocking probability was proposed to solve the network congestion problem in multi-services heterogeneous networks. Users are assigned with different handover priorities according to their service types, and the handover is controlled under blocking probability constraints for the users with same priority. The proposed algorithm disperses the users into different slots to avoid large amount of users selecting the same network at the same time. Simulation shows that the proposed algorithm can keep the handover blocking probability of the system manageable and meet the quality of service requirements of different services.

Key words: group handover, network selection, multi-services, priority queues, handover blocking probability
