METHODS AND ARRANGEMENTS IN A CELLULAR COMMUNICATIONS NETWORK

摘要

The present invention relates to methods and arrangements that make CSG cell discovery more resource efficient. That is achieved by providing the UE with accurate and up-to-date knowledge of the physical cell identity (identities) of its allowed CSG cell(s). Accurate knowledge of the PCI of an allowed CSG cell greatly simplifies the search/ discovery procedure for this CSG cell, in particular the procedure can be made much more resource efficient and UE battery lifetime can be prolonged.
