    Abstract: Methods and apparatuses for facilitating switching HSPA (high speed packet access) serving cells from each of an RNC (radio network controller), base station, and access terminal are provided. The RNC pre-configures an access terminal and each base station in an active set for HS-DSCH operation by providing identification codes identifying each of the base stations. The RNC transmits data packets tagged with sequence numbers to each base station where they are synchronously buffered. The access terminal initiates a handover by transmitting a PDU (protocol data unit) to each of the base stations. The PDU is encoded with the identification code of a target base station and a sequence number of a subsequent packet. The target receives the PDU and directly completes the handover with the access terminal.

    Abstract: PROBLEM TO BE SOLVED: To provide an inter-system handover system that efficiently supports hand-down and hand-up to different radio access technologies.SOLUTION: Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about a neighboring system (target) when a UE 12 reception (RX) capability is both inside and outside a reception range of the neighboring system. A optimized list of neighboring RAT systems (targets) are broadcast from a network, including measurement parameters and reporting instructions. Thereby, reporting driven by the UE 12 minimizes the latency. The UE 12 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 efficiency.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques for quickly and efficiently performing handover.SOLUTION: UE may maintain uplink synchronization with one or more non-serving cells in a candidate set, without having to maintain links with any of the non-serving cells. The UE may update uplink synchronization with the non-serving cells via an access procedure, e.g., send access probes to the non-serving cells and receive timing adjustments from these cells. One non-serving cell with which the UE has maintained uplink synchronization may be selected as a target cell for handover. The UE may then perform handover from the serving cell to the target cell, without performing uplink synchronization during the handover, which may improve handover latency and success rate.
