Patent Searching and Data


Title:
BETTER SYSTEM RESELECTION IN MULTI-SYSTEM WIRELESS COMMUNICATION ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2010/045256
Kind Code:
A3
Abstract:
Disclosed are systems, methods and computer program products for better system reselection (BSR) in a multi-system wireless communication environment. In one aspect, the BSR procedure provisions a mobile device to determine if a currently-registered wireless communication system is the most-preferred system among systems of a similar technology and among systems of different technologies identified in the device's combined preferred roaming list (PRL). The mobile device then activates an intra-system BSR timer if the currently-registered system is not the most-preferred system among systems of similar technology and an inter-system BSR timer if the currently-registered system is not the most- preferred system among systems of different technologies. Upon expiration of the intra- system BSR timer, the mobile device searches for a more-preferred system among systems of similar technology. Upon expiration of the inter-system BSR timer, the mobile device searches for a more-preferred system among systems of different technologies.
