Packet routing in a wireless communications environment

摘要

The claimed subject matter relates to performing routing in a wireless communications system. In more detail, each device associated with a wireless packet-switched network may not be aware of an identity and/or address of a particular point of attachment with respect to a wireless terminal. A data packet that should be provided to a particular point of attachment can be initially directed to a wireless terminal or a one-hop multicast address, for instance. Thereafter, the data packet can be encapsulated in a frame format and identity of the particular point of attachment can be provided in such frame. The frame can thereafter be routed to the point of attachment.

1. A method for routing in a cellular communications environment, comprising:
receiving a data packet of a given type; if the given type corresponds to a first type, selecting a point of attachment from amongst a plurality of available points of attachment for a wireless terminal in the cellular communications environment based on link qualities associated with the plurality of available points of attachment; if the given type corresponds to a second type, selecting a particular point of attachment from amongst the plurality of available points of attachment that is used for routing data packets of the second type irrespective of the link qualities; encapsulating the data packet in a logical link control frame; and indicating that the logical link control frame should be directed towards the selected point of attachment.
