Abstract: A mobile station communicates with an RSVP-aware network over an air interface standard that has a wireless quality of service standard. The mobile station transmits an RSVP message to an end terminal through the network's RSVP-enabled routers. The end terminal transmits an RESV response message back to the mobile station. A base station controller intercepts this message and sets up the wireless resources if possible.

Abstract: A controller module is coupled to a plurality of application modules over a backplane. The backplane comprises a differential bus(s) having a TX and RX data signal, a differential clock signal, and a single ended collision detection line. The application modules transmit data to the controller module. The controller module retransmits a recovered version of the data back to the application modules over the collision detection line. Each application module compares the retransmitted data bits with the data bits it originally transmitted. If the data is not the same, a collision has occurred and the application module removes itself from the bus. If the data is the same as that transmitted originally, that particular application module continues to transmit on the bus. Metastability at the controller module's differential receiver enables multiple differential transmitters to be on the differential bus at the same time.
