Dynamic bandwidth allocation to transmit a wireless protocol across a code division multiple access (CDMA) radio link

摘要

A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

主权项

1. An apparatus comprising:
circuitry to establish a network layer connection with a subscriber unit; circuitry to allocate a plurality of code division multiple access (CDMA) channels for the network layer connection with the subscriber unit, wherein the plurality of CDMA channels includes a data traffic channel comprising a channel bandwidth; circuitry to queue a request to allocate the plurality of CDMA channels for the network layer connection if either the channel bandwidth for the data traffic channel or any of the plurality of CDMA channels are unavailable; circuitry to receive data from the subscriber unit indicating that the subscriber unit has entered an idle state in response to the request to allocate the plurality of CDMA channels being queued; and circuitry to receive data from the subscriber unit indicating an expiration of a traffic timer related to the data traffic channel, and to release the data channel comprising the channel bandwidth while the network layer connection with the subscriber unit is maintained, wherein the circuitry to allocate the plurality of CDMA channels further includes circuitry to receive a network layer message that includes channel selection information for a channel multiplexer that selects among control and data traffic channels based on the channel selection information.
