    摘要： A system and method for switching a session of a User Equipment (UE) in a wireless communication system are provided. According to the method, if the UE performs a handover from a macro base station of a macro cell to a femto base station of a femto cell, a femto base station transmits a path switch request message, which includes a serving gateway relocation Information Element (IE), to a Mobility Management Entity (MME) of the macro cell, in order to request a switching from an existing session of the UE to a new session managed by the femto base station. Then, in response to the path switch request message, the MME switches the existing session of the UE to the new session and transmits a path switch approval message to the femto base station. The serving gateway relocation IE includes information requesting relocation of a serving gateway of the UE to a femto serving gateway within the femto cell.

    摘要： A method and apparatus for determining a location of a User Equipment (UE) in a communication system. A Base Station (BS) connected to a plurality of antennas by cable receives from each of the antennas reception signal information related to an uplink signal transmitted from the UE, identifies an antenna having a partial service area in which the UE is located, using the reception signal information, and determines the partial service area of the identified antenna to be the location of the UE.

    摘要： A method and apparatus for supporting an idle mode of a Mobile Station (MS) in a superframe-based wireless communication system are provided. In a method for operating an MS to support an idle mode in a superframe-based wireless communication system, a paging listening interval is determined based on a Broadcast CHannel (BCH) information Transmit (TX) interval. BCH information including paging information is received during the paging listening interval. The inclusion/non-inclusion of a paging advertisement (MOB_PAG-ADV) message is detected based on the BCH information.

    摘要： A system is provided for performing location update in a wireless mobile communication system that uses an Internet protocol (IP) address and is classified as at least one paging group. A serving base station (BS) sends a message including an identifier of a paging group where the serving BS is located, determines whether there is a change in IP subnet of a mobile station (MS) upon receipt of a location update request from the MS, and upon recognizing a change in IP subnet of the MS, stores information on a new IP subnet and notifies the change in the IP subnet to the MS. Upon detecting a need for location update, the MS sends a request for location update to a serving BS, and receives a location update success notification and an allocated temporary IP address from the serving BS.

    摘要： A method for determining a handoff of a mobile station (MS) in a mobile communication system. In the method, a serving base station (BS) measures a level of a first uplink signal by monitoring an uplink to the MS. The serving BS receives a level of a second uplink signal, measured and reported by at least one neighbor BS. The serving BS determines a handoff for the MS considering the level of the first uplink signal and the level of the second uplink signal.
