Abstract:
1. A method for better system reselection (BSR), the method comprising: registering a mobile device with a first wireless communication system; determining if the first wireless communication system is a most-preferred system among one or more second wireless communication systems of a similar technology and among one or more third wireless communication systems of different technologies; activating an intra-system BSR timer if the first wireless communication system is not the most-preferred system among the one or more second wireless communication systems; activating an inter-system BSR timer if the first wireless communication system is not the most-preferred system among the one or more third wireless communication systems; upon expiration of the intra-system BSR timer, searching for a more-preferred system among the one or more second wireless communication systems; and upon expiration of the inter-system BSR timer, searching for a more-preferred system among the one or more third wireless communication systems; wherein searching for a more-preferred wireless communication system is performed for a predetermined reselection period of time, and wherein duration of the reselection period in which the mobile device searches for a more-preferred system varies based on the number of prior failed attempts to acquire a more-preferred system.
