Abstract: Method and apparatus for efficient routing of mobile node packets. Nodes in a network are configured to classify a received flow from a mobile node to a second node based upon a home address option in a packet in the flow if the address is present. The address is a home address of the mobile node. The classification has associated reserved resources at each node for the received flow. Therefore, the Quality of Service is maintained for the flow between the mobile node and the second node if the mobile node moves to a new location. Resources reserved in nodes in the old path are torn down and released, while reserved resources in nodes in the old and the new path need not be reserved again.

In one embodiment the request is made to obtain a set of link layer addresses (LLAs) that are allocated to individual ones of the network nodes, while in another embodiment the request is made to obtain a group identification (Group_ID) that is used to formulate a set of LLAs that are allocated to individual ones of the network nodes.

Abstract: A “loose ACK” method by which a radio access network of a cellular network monitors wireless transmission of packets according to a layered protocol including a radio layer (near the physical layer) and an upper layer, the method including: a step (23) of slow release—in what is called normal buffer management—in which the upper layer removes from a buffer maintained by the upper layer the oldest packet in the buffer when the buffer is full and a new packet arrives, and does so independently of whether the packet being removed has been acknowledged by the radio layer of the terminal; and a step (24) of local acknowledgement in which the radio layer sends an acknowledgement to the upper layer on the occurrence of a predetermined event. The local acknowledgement can trigger either special mode buffer management or release of the buffer to a target (entity or layer).

Abstract: A system and method for determining which of a user node and an IP network will establish Quality of Service (QoS). The IP network transmits a message indicating whether the IP network, the user node, or both the IP network and the user node are capable of establishing QoS. If only the IP network or the user node can establish QoS, then it is done in that manner. If either can establish QoS, the user node may select which entity will establish QoS.

Abstract: A method and apparatus for eliminating the inefficient use of network bandwidth cause by numerous acknowledgment transmitted by the receiver to the transmitter by providing sparse feedback from the receiver to the transmitter indicating receipt of packets having headers to be used as reference headers. In the invention, upon receipt in the receiver of a packet having a reference header, a feedback is provided to the transmitter indicating receipt of the packet having the reference header. Thereafter, the receiver waits a predetermined period of time before providing another feedback in response to another packet having a reference header. The predetermined period of time allows time for the feedback to be received by the transmitter and for information from the transmitter indicating receipt of the feedback to be received by the receiver.
