Method and means for redistribution of subscriber information in UMTS networks where the nodes are arranged in pools

摘要

The present invention relates to method and means for a system initiated subscriber information redistribution in order to achieve a load redistribution within a pool of core network nodes. The subscribers, that are affected by the redistribution, are determined by the bit values in their TMSI's. These specific TMSI's are then arranged to be treated as invalid by the cellular system. Messages etc. from subscribers with invalid TMSI's will be "trapped" in the cellular system and the subscriber information that belongs to these subscribers will be redistributed to new core network nodes.
