  • Switching multiple link layer resources for media independent handover
    Patent number: 8274946
    Abstract: A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions.

    Abstract: Embodiments contemplate one or more techniques for packet filtering. One or more embodiments may apply specific routing and/or forwarding rules on some or each packet when a device has one or more, or multiple, interfaces. Contemplated filtering techniques may be implemented in a module and/or without modifying an IP stack. The contemplated packet filtering techniques may apply to a terminal in uplink and/or downlink as well as to any network node. An incoming packet table may be created using 5-tuple, 6-tuple, and/or tags, among other mechanisms, to support incoming and/or outgoing packet filtering.

  • Method and apparatus for identifying mobile network protocol capabilities
    Patent number: 8238261
    Abstract: A method and apparatus for improving handover in an IEEE 802.21 compliant communication network. A query is transmitted from a wireless transmit/receive unit (WTRU) to a media independent handover (MIH) server (MIHS). The WTRU includes a target point of attachment (PoA) and/or a preferred mobile inter protocol (MIP) method. The WTRU receives a response from the MIHS indicating the MIP method supported by the target PoA. Based on the received response, the WTRU may make an informed decision regarding handover.
