    摘要： A system and method for handoff in an integrated cell. A user equipment selects an integrated cell as a target cell supporting a target network based on a white list and physical cell identities. A cell-to-cell handoff is performed to the target cell. After the cell-to-cell handoff, a base station of the target cell establishes a communication session directly to a service. Then, the user equipment determines whether or not a physical cell identity of a base station of the target cell is an integrated physical cell identity. The user equipment turns on a module for the target network when the physical cell identity of the base station is determined to be the integrated physical cell identity. A heterogeneous-network handoff is then performed, and the base station communicates directly with a service server using a mapping table in order to seamlessly provide the service to the user equipment.

    摘要： Described embodiments provide a method of a circuit switched (CS) fallback procedure at a first network providing only a packet switched (PS) service. A CS fallback procedure may be initiated upon a receipt of a call associated with a CS service. One of carriers assigned to a second network that provides a circuit switched (CS) service may be selected. Then, a second network cell mapped to a serving cell of the first network and using the selected carrier may be selected as a target cell. The user equipment may be handed over o to the selected second network cell in order to provide a requested CS service.

    摘要： The disclosure is related to measuring macrocell quality of a macrocell using femtocells. A method may be provided for measuring macrocell quality of at least one macrocell using a femtocell base station. The method may include measuring, by the femtocell base station, macrocell quality of at least one macrocell based on event information, generating macrocell quality report information based on a result of the measuring, and transmitting the generated macrocell quality report information to a server through a femtocell gateway. The measuring macrocell quality may include determining whether a macrocell identifier is present in the event information, measuring the macrocell quality of a target macrocell corresponding to the mermen identifier of the event when the macrocell identifier is present in the event information, and measuring the macrocell quality of substantially all neighbor macrocells when the macrocell identifier is absent from the event information.

    摘要： Provided are an ARQ apparatus and method for a multihop system in a broadband wireless access communication system. The ARQ method of a relay includes determining if the relay successfully receives specific data from a source and transmitting the specific data to a destination; receiving feedback data from the destination and determining if the destination successfully receives the specific data; generating feedback data including data indicating if the relay and the destination successfully receive the specific data, and outputting the feedback data to the source; and retransmitting the specific data, when the relay successfully receives the specific data but the destination fails to receive the specific data. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.
