Abstract:
A method of extending RSVP QoS signaling to a wireless network comprising:intercepting a PATH message to or from a mobile terminal served by the wireless network, modifying its contents to reflect constraints of the wireless network and forwarding the PATH message; intercepting a RESV message received in response to the PATH message; and after intercepting the RESV message, in sequence: performing a QoS mapping from a RSVP QoS specified in the RESV message to wireless network parameters; checking if an existing wireless traffic channel satisfies the wireless network parameters and if not coordinating the establishment of a wireless traffic channel which satisfies the wireless network parameters; and forwarding the RESV message if a wireless traffic channel could be established and generating an RESVerr message if a wireless traffic channel could not be established.
