Disclosed herein is a technique for enhanced parameter negotiation in Evolution-Data Optimized (EVDO) communication systems that use Generic Configuration Protocol to negotiate session parameters or session attributes. The technique reduces the number of parameter negotiation cycles involved during the session configuration process. A new AlternateValueAllowed field is added in the attribute record. The Configuration Request message sent by the initiator allows the Configuration Response message responder to send the responder's preferred attribute value to the initiator, when the Configuration Request message does not contain the preferred attribute value of the responder. Such a modified attribute record structure obviates the need for multiple attribute negotiation cycles, and therefore saves session negotiation time.

The invention relates to a method for managing the mobility of a mobile terminal, while receiving a service via an access node of a mobile communication network. The mobile communication network has overlapping pool areas, while the access node is assigned to at least two pool areas simultaneously. After the UE changes to the access node of the overlapping area, it is proposed that the mobility management entity serving the UE arbitrarily selects a prospect user plane entity for transporting service data into the next pool areas, and requests from the service provider information about UPEs handling this service. After the actual attachment to an access node within the new pool area, the handover is finalized by changing the UPE from the old one to the selected UPE in the new pool area. Thereby, the data path from the service provider to the UE is constantly being optimized.

A wireless communication transceiver compensates a given received signal for retransmission interference, if (uncompensated) decoding of the given received signals fails. The transceiver estimates the retransmission interference bearing on the given received signal based on hypothesizing that another user (or users) mistakenly transmitted in the same time interval, using some or all of the same channel resources as were allocated to the given received signal. The transceiver may retain information in any given interval, indicating the channel allocations used for those user signals successfully received in that interval. The retained information allows the transceiver to determine, with respect to a given signal received in a current time interval, which other users would be interfering users if they mistakenly retransmitted in the current time interval. The transceiver may target its compensated decoding, which may be iterative, to the most likely and/or most significant ones of the potentially of interfering user(s).

A communication system (100) transmits data packets from a sender (120A) to a receiver (130A) using hybrid automatic repeat request processes. The sender redundantly encodes each packet, divides the packet into subpackets, and sends the subpackets to the receiver in a time-interlaced manner. When the receiver returns a positive acknowledgement of a subpacket using an acknowledgement channel, the sender terminates transmission of the subpackets. The sender interprets the signals on the acknowledgement channel using a metric resulting from correlation of the signals with positive and negative acknowledgement symbols. The sender interprets low correlation of the acknowledgement channel signal with both positive and negative acknowledgement symbols as a preamble miss, and terminates transmission of the subpackets. After termination, the packet may be rescheduled for transmission. Early termination of packet transmission after a preamble miss improves bandwidth utilization and decreases latency of the packet with the missed preamble.

A method of manufacturing two screens in a jig by laying a length of woven wire cloth across two rectangular frames laid side by side in the jig with longer edges abutting, and orientating the cloth so that the warp wires extend continuously across the two screens. The cloth is tensioned and bonded to the frames after which it is severed along the join and surplus cloth is trimmed away from the edges of the frame. If the cloth has a square mesh and the warp wires are of greater cross-section than the weft wires, the warp wires will extend across the width of the frame, and if the cloth has a rectangular mesh, the greater number of warp wires per unit length also extends across the width of the frame. In each case warp wires will resist the stresses across the width of the central region of each opening.
