摘要： Control of a data packet buffer in a communication system is described. Control of a data packet queue in a transmission link is shown. In the queue there is stored a plurality of received data packets that are intended for transmission over a wireless interface. Selected packets are discarded from the queue without the selected packets having been transmitted. A packet is selected for discarding depending on at least the length of time the packet has been stored in the queue. The discarding of a selected packet is effectuated on condition that at least a predetermined time period has elapsed since a previous discarding of a packet has taken place. Such a solution is advantageous in that, for varying transmission bandwidth conditions in the transmission link, it is possible to achieve good link utilization and throughput, while at the same time enabling a low end-to-end delay for packets transmitted in the link.

摘要： A method of scheduling data for transmission over the air interface of a wideband code division multiple access network, said data being transported over the air interface on a downlink shared channel. The method comprises receiving data in the form of IP packets at a radio network controller, segmenting said IP packets into protocol data units, and forwarding said protocol data units from the radio network controller to a radio base station serving one or more user terminals. The radio network controller identifies to the radio base station the protocol data units belonging to a common IP packet. At the radio base station, each protocol data unit is scheduled for transmission over the air interface in dependence upon the IP packet to which it belongs.

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 invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.

摘要： A method of controlling a data unit relay device is described, applied to a relay ARQ protocol in accordance with which a source peer sends data units to a destination peer via at least one relay peer. The relay ARQ protocol provides for a first type and second type of receipt information, where the first type is indicative of a correct receipt at a relay peer, and the second type is indicative of a correct receipt at the destination peer. In a data unit relay device that is arranged for deliberately dropping data units of the relay ARQ protocol under one or more predetermined conditions, a procedure is provided for indicating to the source peer and the destination peer that a data unit has been deliberately dropped and for identifying the deliberately dropped data unit, such that the source and destination peer may perform retranmission control for the dropped data unit as if it had been successfully received at the destination peer.

摘要： A queue buffer control system is described, in which a queue length parameter QL is compared with a length threshold value Lth for triggering a congestion notification procedure that comprises a decision procedure for deciding whether to perform congestion notification or not. Also, an automatic threshold adaptation procedure S5 for adapting the threshold Lth on the basis of an estimated link capacity value LC is provided. The automatic threshold adaptation procedure S5 is operable in one of at least a first and a second adaptation mode, the first adaptation mode being associated with minimizing queuing delay and adapting the threshold value Lth on the basis of n•LC, where n≥1, and the second adaptation mode being associated with maximizing utilization and adapting the threshold value Lth on the basis of m•LC, where m>1 and m>n.
