    摘要： A method and apparatus for providing wireless communication services, (e.g., multimedia broadcast multicast services (MBMS)), are disclosed. A wireless transmit/receive unit (WTRU) detects a plurality of target cell evolved Node-Bs (eNodeBs) that neighbor a serving cell eNodeB. The WTRU evaluates cell reselection criteria and determines a neighboring target cell eNodeB to reselect. The WTRU receives and reads master information block (MIB) and system information messages of the neighboring target cell eNodeB, and confirms that the determined neighboring target cell eNodeB is not part of a multimedia broadcast single frequency network (MBSFN). The WTRU identifies the neighboring target cell eNodeB to the serving cell eNodeB. The WTRU then receives and reads MIB messages of the neighboring target cell eNodeB again to determine whether the system information has changed and, if so, the WTRU reads the system information and reselects to the neighboring target cell eNodeB, which provides the wireless communication services.

    摘要： A method and apparatus are used to perform a Circuit Switched (CS) fallback in wireless communications. The Non-Access Stratum (NAS) of the apparatus determines whether to perform a CS fallback based on an Internet Protocol (IP) Multimedia Subsystem (IMS) registration status, and sends a service request indicating a request to perform the CS fallback when the WTRU is attached to a CS domain. The apparatus also includes an Access Stratum (AS) that receives the CS service request from the NAS, sends an indication of the CS service request in a Radio Resource Control (RRC) message to an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), wherein the RRC message includes CS service information, and receives a handover command in response to the CS service request.

    摘要： Various procedures for operating a wireless transmit/receive unit (WTRU) in Long Term Evolution (LTE) Idle mode are described. The procedures include: methods for applying cell reselection priorities in the WTRU, methods for converting a mobility state of the WTRU between operating modes, a method for assigning a mobility state to the WTRU, and a method for determining whether the WTRU may access a closed subscriber group (CSG) cell. Also described are methods and an apparatus on the operations of the LTE mobility state transition mechanism between LTE WTRU Idle mode and Connected mode, a definition of the Pcompensation parameter for LTE, inter-frequency and inter-radio access technology cell reselection priority validity definitions, and coverage extension principles for CSG cells.
