    Abstract: The link layer (68, 64) of the sending end of a wireless link (66) is enhanced (10, 74) by providing a mechanism for discriminating (36, 38; 79, 82) between special, critical or otherwise important packets from among a plurality of packets send over the wireless link. Special link layer treatment (42; 89) is accorded to such special, critical or otherwise important packets, while the remaining packets are subjected to normal link layer treatment (44; 86) before transmission over the wireless link.

    Abstract: The present invention provides an enhanced H-ARQ scheme that optimizes bandwidth utilization and spectrum efficiency. When an H-ARQ attempt is unsuccessful due to loss or error over a hop between the BS and MS/SS, then only the first node in the hop chain that fails to decode the packet transmits another H-ARQ attempt. The BS determines the first node that fails on decoding based on certain information such as the feedback information sent from the nodes on the path. The previous node of the failed node is then instructed to retransmit by the BS.

    Abstract: A method for operating a firewall includes: in response to the firewall receiving a TCP SYN request packet that is sent towards a first node from a second node, said TCP SYN request packet comprising a sequence value (“seq”), sending to the second node a SYN|ACK packet, said SYN|ACK packet comprising a seq and an ack_sequence value (“ack_seq”), where ack_seq of the SYN|ACK packet is not equal to the TCP SYN request packet's seq+1; and in response to the firewall receiving a TCP RST packet from the second node, verifying that the seq in the TCP RST packet matches the ack_seq of the SYN|ACK packet and, if it does, designating the connection with the second node as an authorized connection.

    Abstract: The invention proposes a method for controlling a packet transmission between a sender and a receiver sent via a packet transport protocol, the receiver being a mobile network element, comprising the steps of detecting whether a mobility event has occurred, detecting whether a downlink packet loss has occurred, and providing, in case a mobility event and a packet loss has been detected, an indication to the sender that a packet loss due to mobility has occurred.
