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.
摘要翻译：在无线通信网络中，其中基站从移动台接收用于解压缩和解密的协议数据单元（PDU），用于有序的顺序传送作为服务数据单元（SDU）到相关联的核心网络，本文给出的教导提供了一种支持无缝将移动台从源基站切换到目标基站。作为示例，本文的教导适用于由3GPP公布的基于E-UTRA规范的网络。然而，该示例是非限制性的，因为本文的教导适用于在切换时采用顺序数据传递和重复数据检测的任何网络。广泛地说，源基站将无序SDU和相应的序列号信息转发给目标基站以支持无缝切换，目标基站使用该信息来根据需要重新分组以重新分组。

摘要： The present invention relates to methods and arrangements in a telecommunication system, in particular to transmission of uplink buffer status information. The buffer status reports are complemented with happy bits carrying buffer status information which are interpreted according to a first semantic or to a second semantic. The first semantic is based on the QoS parameter of the logical channel whereas the second semantic is based on the amount of data available for transmission across the first logical channel group in the user equipment.

摘要： User equipment (200) in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.

摘要： Methods and devices are disclosed for forwarding data packets during handover in a packet-switched wireless communications system, such as a 3GPP Long-Term Evolution/System Architecture Evolution system. In an exemplary method, a source base station node (410, 900) determines (520) that handover of at least one radio bearer for a served user terminal (160) to a target base station node (430, 900) is imminent. The source base station node (410, 900) classifies (530) a plurality of data packets into two or more data flow classifications according to a transmission status for each data packet, a service requirement for each data packet, or both and selectively forwards (540) one or more of the data packets to the target base station node (430, 900) based on the data flow classification for each data packet. In some embodiments, the source base station node (410, 900) classifies (530) the data packets by inspecting (610) an Internet Protocol header for each packet to determine a corresponding service requirement. In some embodiments, the source base station node (410, 900) classifies (530) data packets by evaluating (650) a radio link control status to determine a transmission status for each data packet. In either case the source base station node (410, 900) selectively forwards (540) data packets corresponding to one or more of the classifications. For example, data packets associated with a reliable delivery service requirement may be forwarded while data packets associated with a maximum delay service requirement are not.

摘要： A method (400) for use in a cellular system with at least one controlling node (110), eNodeB, which controls user terminals, UEs (130), in a cell (120). According to the method, a UE can be in one of at least two different states (410), an idle state, a DRX state, and an "on duration" state. A UE (130) can receive at least a first (420) and a second (425) type of traffic from its eNodeB (110). If (415) the first type of traffic is received by a UE during an on duration period, the UE assumes the idle (DRX) state at the end of the on duration period, and if (430) the second type of traffic is received by the UE during an on duration period, the UE prolongs the current on duration period by a certain amount of time.

摘要： A method (300) for use in a cellular system (100) with a controlling node (110) and user terminals, UEs (130). In the system, UEs can assume one of at least two states, a non-listening state, i.e. a state during which a UE (130) does not listen for data from its controlling node (110), and a listening state, an "on duration" state. According to the method (300) a UE in the system is able to alternate (310) 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 and mobile terminal for providing uplink scheduling information to a scheduler in a wireless telecommunication system. When a logical channel having data available to transmit triggers a buffer status report, the mobile terminal determines whether a priority level associated with the logical channel exceeds a predefined threshold. If so, the mobile terminal performs a scheduling request procedure with the scheduler. If not, the mobile terminal delays the scheduling request procedure until a predefined timing event has occurred. The predefined timing event may be at least one of expiration of a timer, a radio bearer associated with the logical channel becoming active, and if the scheduling request procedure is being performed using a contention-based random access, contention resolution succeeding for the mobile terminal.

摘要： Methods and apparatus for producing a compressed buffer status report (400) for use in a wireless network are disclosed. In several of the disclosed embodiments, a wireless terminal (160) forms a compressed buffer status report (400) that includes a field (410) of one or more bits that indicate an overall status corresponding to all or substantially all of the uplink data buffers for the wireless terminal (160), along with one or more fields (420) that indicate buffer status for specific corresponding radio bearers or groups of radio bearers. Accordingly, a small buffer report (410) may be sent in-band with the uplink data transmission, such as in headers (810) of one or more MAC packet data units (800), to convey information about the status of the wireless terminal's buffers, both for all the buffers (i.e., collectively), and for each of several high-priority radio bearers or groups of radio bearers.
