    • 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. The communication system has a radio frequency channel (400) with time slots (406, 408) 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 (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)包括无线终端(102)和基站(104)。 无线终端通过射频信道(106)与基站通信。 基站经由分组网络彼此互连和其它网络元件。 通信系统具有用于传输诸如流式音频和视频之类的延迟敏感数据以及非延迟敏感数据的具有时隙(406,408)的射频信道(400)。 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。

    • Methods for enabling floor control are performed in an endpoint terminal (140, 142, 146) and a session controller (106). The session controller: receives (410) a message requesting a session that includes an SDP packet with a requested floor control profile having a requested set of floor control parameters or a requested list of potential floor owners; accepts (410) the session; determines (420) a final floor control profile having a final set of floor control parameters and a final list of potential floor owners; and communicates at least a portion of the floor control profile within a system (100). The endpoint terminal: communicates a message requesting a session that includes an SDP packet with a requested floor control profile; and receives a message having an SDP packet with a final floor control parameter. The final floor control profile may be the same as or different from the requested floor control profile.
    • 在端点终端(140,142,146)和会话控制器(106)中执行用于启用楼层控制的方法。 会话控制器:接收(410)请求包括SDP分组的会话的消息,所述会话具有请求的楼层控制简档,所述请求的楼层控制简档具有请求的楼层控制参数集合或所请求的潜在楼层所有者列表; 接受(410)会议; 确定(420)具有最终楼层控制参数集合的最终楼层控制简档和潜在业主的最终列表; 并且在系统(100)内通信楼层控制简档的至少一部分。 端点终端:通过请求的楼层控制简档来传送请求包含SDP包的会话的消息; 并接收具有最终楼层控制参数的具有SDP包的消息。 最终楼层控制简档可以与请求的楼层控制简档相同或不同。
