METHOD AND APPARATUS FOR SEARCHING FOR CLOSED SUBSCRIBER GROUP CELLS

摘要

PROBLEM TO BE SOLVED: To provide a procedure that addresses the problems, keeping in mind the restrictions imposed by the standardization bodies, in which: while some tentative solutions have been proposed for active mode mobility between LTE macro-cells and CSG cells, no comprehensive solution incorporating different types of mobility has been developed as yet.SOLUTION: A method and apparatus for searching for CSG cells are described. A wireless transmit/receive unit (WTRU) transmits, to a network of CSG cells, a measurement/cell-search gap request message including a cause value having at least one bit that indicates whether the request message was transmitted due to a manual cell search command or a WTRU autonomous determination. The WTRU receives a measurement/cell-search gap allocation message from the network in response to the measurement/cell-search request message.
