摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： A method for use in a cellular system with a controlling node and user terminals, UEs. In the system, UEs can assume one of at least two states, a non-listening state, i.e. a state during which a UE does not listen for data from its controlling node, and a listening state, an “on duration” state. According to the method a UE in the system is able to alternate between said two states according to a certain scheme, the scheme according to which a UE in the system alternates between said two states being dependent on whether or not data units which are transmitted between the UE and its controlling node are received entirely and correctly within an initially allocated resource for each data unit.

摘要： A method in a user equipment (UE) includes transmitting, to a first radio base station, one or more protocol data units (PDUs) that are each associated with a respective Internet Protocol (IP) packet. The method also includes receiving one or more feedback indications from the first radio base station, each indicating whether a corresponding PDU was successfully received, and transmitting a retransmission of at least one PDU based on the feedback indications. Additionally, the method includes determining a time point for performing a cell change based on whether the first radio base station has not successfully received all of the PDUs associated with IP packets for which a complete IP packet has been transmitted and performing the cell change at the determined time point.
