摘要： A method and apparatus for negotiating capability information for a broadcast service in a communication system. In one embodiment, the generic capabilities are pre-configured in BSC, which provides the generic capability information to MS and to PDSN based on a listing of available BC services and the corresponding capabilities. Another embodiment pre-configures PDSN with the generic capability information. According to still another embodiment, PDSN is pre-configured with the generic capability information, wherein the MS queries the PDSN directly for generic capability information via a PPP connection. In yet another embodiment, the MS queries the PCF, which in turn queries all of the PDSN in the system. The PDSN responsible for the BC responds to the query. Where multiple PDSNs may support the BC, the first to respond using multicast addressing obviates the need for the others to respond.

摘要： Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A trigger recognized at the transmission node initiates a broadcast transmission, and the resultant set up of a transmission path. A termination trigger then indicates that the transmission node is not serving users desiring the broadcast transmission, and in response the transmission path is shut down. In one embodiment, a multi-cast call, such as a group call, may be transmitted to active users via uni-cast channel(s) or multi-cast channel(s) based on a predetermined criteria, such as number of active users.

摘要： Systems and methodologies are described that facilitate relocating an IP buffer from a conventional location in a user device handset to a radio-access network (RAN) interface in order to reduce acquisition delay in the user device. By performing IP buffering at the transmission side of a forward link transmission, acquisition time can be reduced by approximately 5-7 seconds. Additionally, a physical layer aware encoder can be employed, which has knowledge of transmission constraints associated with, for example, a conventional DVB-H transmission protocol, and can parse streaming media into 1-second segments that can be pre-packaged in a current superframe for display at a subsequent time.
摘要翻译：描述了有助于将IP缓冲器从用户设备手持机中的常规位置重新定位到无线电接入网络（RAN）接口的系统和方法，以便减少用户设备中的采集延迟。通过在前向链路传输的发送侧执行IP缓冲，获取时间可以减少约5-7秒。另外，可以采用物理层感知编码器，其具有与例如常规DVB-H传输协议相关联的传输约束的知识，并且可以将流媒体解析为可以预先封装在当前的1秒段中超帧在随后的时间显示。
