CPC-assisted Network Selection Strategy

In a beyond 3G context, many wireless technologies can cooperate or interoperate, within dynamic and reconfigurable networks. In this changing radio environment, the challenge for the cognitive terminal is to be able to connect to the relevant network, according to several criteria. E2R has developed concepts and solutions for a Cognitive Pilot Channel (CPC) to bring enough information to the terminals for network selection when terminals are proceeding either initial connection or handoff. This paper focuses on the network selection strategy according to the information which could be brought by CPC and also some information of user preference stored in terminals previously. In the latter part, a network selection algorithm is presented, which can both improve the system performance and satisfy users well.
