Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The teachings presented herein enable a user terminal to perform a fast recovery from a radio link failure. In one aspect, the improvement in recovery time is achieved by commanding or otherwise causing the user terminal to perform radio link failure (RLF) recovery at a cell that is known to possess the user context, while considering that this cell should yield good radio conditions (if not the best) to the user terminal. A cell may be predefined for use by the user terminal in recovering its radio connection. Based on providing signal strength thresholds to the user terminal, for use in determining whether to use a predefined cell for reconnecting to the network, the user terminal attempts RLF recovery first in the predefined cell. By providing user context to the predefined cell in advance of a recovery attempt by the user terminal, the time for recovery is lessened. Note that the user terminal also may infer which cells are preferred.

Abstract: A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer (48) of the client device.
