    摘要： A method and apparatus for minimizing data forwarding between Evolved Node Bs (ENBs) during a handover. A User Equipment (UE) sends a status report to an ENB of a source cell immediately before the handover occurs. In this manner, a target cell avoids retransmission of the RLC PDUs, which were successfully transmitted but have not yet been ACKnowledged (ACKed) by the UE, thereby minimizing the amount of data being forwarded from the ENB of the source cell to an ENB of the target cell.

    摘要： Improving communication efficiency in handover re-establishing an ARQ entity in a mobile communication system is disclosed. The method includes transmitting first Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) correctly received from the source cell, together with a special indication requiring reordering of the first PDCP PDUs, from a Radio Link Control (RLC) receiving buffer to a PDCP receiving entity when a handover command message from a source cell to a target cell is received; buffering the first PDCP PDUs in a PDCP PDU reordering buffer by the PDCP receiving entity in response to the special indication; and when a second PDCP PDU is received from the target cell through a new RLC receiving entity for the target cell, outputting third PDCP PDUs up to a PDCP PDU before a first missing PDCP PDU having a sequence number higher than that of the second PDCP PDU from the PDCP reordering buffer. In the method, a PDCP entity performs reordering, thereby improving efficiency of communication.

    摘要： A method of changing the serving cell in a cellular communications network is provided. A radio communications link is established between a serving network node of a serving cell and a mobile terminal. The mobile terminal sends radio measurement reports for cells other than the serving cell. Once a predetermined condition has been fulfilled, a pre-configuration is performed to establish a radio communications link for one or more cells being a candidate for a new serving cell.

    摘要： A method and apparatus for controlling measuring the frequency of a new cell within a forbidden registration area when a User Equipment (UE) enters into the new cell in a mobile communication system are provided. If the UE recognizes the new registration area as forbidden, the UE does not measure the frequency of the current cell for a predetermined reference time, and searches for a suitable cell for a normal service by measuring other frequencies. If no suitable cell in the other frequencies is found, the UE removes a measuring limitation and searches for an acceptable cell for a limited service by measuring frequencies including frequency of the current cell.

    摘要： A user equipment (UE) is provide which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.
