Abstract: An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.

Abstract: Techniques for performing handover of a user equipment (UE) in a cell-to-base station manner are described. The UE may receive a handover command to perform handover from a source base station to a target base station. The source base station may send context information for the UE to the target base station, and the context information may be available to all cells of the target base station. The UE may attempt handover from a serving cell of the source base station to a first cell of the target base station. The UE may attempt handover to a second cell of the target base station if the handover to the first cell fails. The UE may (i) receive the first and second cells from the source base station or (ii) receive only the first cell from the source base station and determine the second cell based on broadcast system information.

Abstract: UTRAN ENHANCEMENTS FOR THE SUPPORT OF INTER-CELL INTERFERENCE CANCELLATIONSystems and methodologies are described that facilitate providing uplink inter-cell interference cancellation. A radio network controller can receive measurement reports in order to identify non-serving nodes that are receiving interference from user equipment. Based on evaluation of such measurement reports, an interference message can be communicated to a Node B, wherein such measurement report can include information that allows the Node B to cancel or terminate the interference caused by such identified user equipment.Figure 4

Abstract: A method for SRNS relocation comprises sending a relocation request from a Source Node B+ to a Target Node B+ based on measurements received from a User Equipment; sending a Physical Channel reconfiguration message from the Source Node B+ to the UE; forwarding packet Data Units (PDU) from the source Node B+ to the Target Node B+; and performing physical layer synchronization and radio link establishment with a target cell of the Target Node B+.

Abstract: Firstly, the invention concerns a method for access control in a femto cell, comprising: assigning at least one femto cell to correspond to a first identifier that identifies valid access to said femto cell; storing a list comprising at least one second identifier and at least one first identifier, wherein a second identifier corresponds to an AT and said list indicates valid first identifier and second identifier pairs; receiving, at a femto cell, a request from an AT for access (1030); sending, by the femto cell, the first identifier to at least one access control component (1035); determining, from said list, whether a second identifier for said AT corresponds to a valid first identifier for a said femto cell (1040); and granting access to said AT at said femto cell in response to said request if said AT is identified. Secondly, the invention concerns a method for paging in femto cells.
