    • A radio frequency communications system (100) includes wireless terminals (102) communicating with base sites (104) over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. A radio frequency channel (400) includes time slots (406, 408) for transmission of 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 (704, 706, 708). Each packet of data transmitted over the wireless channel has a type of service field (900). The type of service field has a precedence or priority value (902) and a service type (904). 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.
    • 射频通信系统(100)包括通过射频信道(106)与基站(104)通信的无线终端(102)。 基站经由分组网络彼此互连和其它网络元件。 射频信道(400)包括用于传输诸如流式音频和视频之类的延迟敏感数据和不延迟敏感数据的时隙(406,408)。 提供一种方法和装置,用于确定射频信道中的时隙是否被分配给延迟敏感数据或非延迟敏感数据(704,706,708)。 通过无线信道发送的每个数据分组具有一种服务字段(900)。 服务类型具有优先级或优先权值(902)和服务类型(904)。 优先级值用于确定哪个分组应在下一个射频信道上传输,业务类型决定传输协议。
