Abstract: An apparatus, a signaling method, and a tangible machine-readable medium thereof for callback handover procedure in a femto-network are provided, wherein the femto-network comprising a plurality of femto base stations. The apparatus comprises a storage module, a receiving module, a transmission module, and a determination module. The storage module is configured to store and restore information of the femto BS, the information indicating a relation between the apparatus and the related stations. The receiving module is configured to receive the inbound handover signals and outbound handover signals. The transmission module is configured to transmit the inbound handover signals and outbound handover signals. The determination module is configured to determine whether generating inbound handover signals or outbound handover signals.

Abstract: A method for a handover procedure comprises detecting a status of a backhaul connection between an original femto base station and a backbone network, and sending a handover request message including a reason code and/or flag to at least one mobile station served by the original femto base station, then the at least one mobile station re-associates with at least one base station other than the original femto base station.

Abstract: The apparatus, signaling method, and tangible machine-readable medium thereof for time synchronization procedure in a cellular network are provided, wherein the network comprising a plurality of femto base stations and relay stations. The source of providing time synchronization information to femto base stations and relay station could be macro base station, femto base station, relay station or mobile station. The apparatus comprises a clock module, a receiving module, a transmission module, and a determination module. The clock module is configured to generate clocks to synchronize with the network.
