摘要： The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.

摘要： UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n = the number of bits in C/T field.

摘要： A method of optimising the use of radio resources in a mobile radio communication system during a combinational multimedia session involving circuit switched and packet switched sessions between user terminals, communicating over two cascaded radio links the method comprising: disabling an in-sequence delivery option of packets for the radio link of the sending side of the packet switched session. Another method comprises the step of altering the TCP segment size and/or the TCP initial window size in order to avoid that the packet switched session remains in slow-start conditions for too long.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
摘要翻译：根据本发明的方法和设备解决和/或防止由ACK / NACK错误引起的HARQ系统中丢失的协议同步。一个实施例检测基于NDI的重传协议的丢失同步错误，并通过发送显式RESET消息来恢复同步。响应于RESET消息，发送器中止当前PDU的发送并发送新的PDU和对应的NDI。另一个实施例通过在逐个分组的基础上发送调度授权来防止协议同步错误。接收器基于接收到的PDU的错误评估向发送器发送后续显式调度许可。除非接收到后续的显式调度授权，否则发送器不会发送下一个PDU。

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.
