Method and appatatus for determining and reserving bandwidth for transmitting delay-sensitive streaming data over a radio frequency channel
First Claim
1. A method for allocating bandwidth on a radio frequency channel for transferring delay-sensitive data, the method comprising the steps of:
- receiving a request to transfer delay-sensitive application data, wherein the request includes parameters defining an application bandwidth requirement;
converting the application bandwidth requirement into a channel bandwidth requirement, wherein the channel bandwidth requirement is related to a bandwidth characteristic of the radio frequency channel;
determining whether the channel bandwidth requirement exceeds an available channel bandwidth; and
reserving the channel bandwidth requirement if the channel bandwidth requirement does not exceed the available channel bandwidth.

Abstract
A radio frequency communications system (100) includes wireless terminals (102) and base sites (104). The wireless terminals communicate with the base sites over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. A method and apparatus determine for a particular delay-sensitive application on the wireless terminal, for example, an audio or video transmission, the requirements for bandwidth for transmission over the radio frequency channel (500, 502). After the requirements on the radio frequency channel are determined, the necessary channel bandwidth, if available, is reserved or allocated to guarantee performance to the application (510). The reserved bandwidth is utilized by selectively granting access to the radio frequency channel on the basis of the bandwidth allocated to the device.
