Title: OPTIMIZATION OF SYSTEM INFORMATION READING USING CHANGE OF AREA INFORMATION
Abstract:
The present invention relates to a wireless terminal for operating in a cellular network comprising a plurality of base stations the wireless terminal is configured to camp on, the wireless terminal comprising a transceiver, at least one processor and a memory, the transceiver being configured to receive a set of system information, each of the system information respectively transmitted by the base stations comprising an area system information transmitted by one of the base stations, the area system information is common for a local area covered by said base station and at least one other base station, and the processor being configured to store a received area system information in said memory, wherein the processor of the wireless terminal is further configured to process a later transmitted area system information only in case of detection of: -an area identifier transmitted with the system information indicating a change of area, or -a system value change field transmitted with the system information indicating a change of values of area system information values, or -an overrun field transmitted with the system information indicating an overrun of the system value change field.
