Abstract
A radio frequency communications system () includes wireless terminals () and base sites (). The wireless terminals communicate with the base sites over a radio frequency channel (). The base sites are interconnected to each other and other network elements via a packet network. The communication system has a radio frequency channel () with time slots () for transmission of both delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data (). Each packet of data transmitted over the wireless channel has a type of service field (). The type of service field has a precedence or priority value () and a service type (). The priority values are used to determine which packet should be transmitted across the radio frequency channel next and the service type determines the transmission protocol.
