FAST NOTIFICATION OF RELATIVE RADIO-ACCESS TECHNOLOGY PRIORITIES

摘要

System information transmitted from a wireless network is enhanced to contain additional information that indicates the relative priority between neighboring cells or frequencies in multiple Radio-Access Technologies, such as GERAN, UTRAN and E- UTRAN. In an example method implemented in a mobile station, a system information message of a first type transmitted by a base station is read. The mobile station determine whether one or more RAT priority bits are present in the system information message, wherein the presence or absence of the one or more RAT priority bits indicates whether additional ones of a plurality of available system information messages of the first type must be read before inter-RAT cell reselection may begin. If RAT priority bits are present, the mobile station selectively initiates inter-RAT cell reselection based on the one or more RAT priority bits.
