摘要： The present invention provides a method for receiving broadcast data in a system where broadcast data is transmitted on a plurality of frequencies. A user device monitors (302) a first frequency (108) for broadcast data to be transmitted on the first frequency. The device receives on the first frequency a notification of a broadcast data session which is to be sent on a second frequency (114) that is different from the first frequency. The device then determines a configuration associated with the second frequency and in accordance with receiving the broadcast data session and then configures (310) to receive the broadcast data session in accordance with the determined configuration. After receiving the broadcast data session, the device returns to monitoring the first frequency.

摘要： A communication system (100) determines whether to establish a point-to-multipoint communication or a point-to-point communication for conveyance of Multimedia Broadcast Multicast Service (MBMS) data based on a number of mobile stations (MSs) (102-104), both idle mode and maintaining an active connection, serviced by the system and subscribed to an MBMS service. The system, broadcasts (306) a control message that includes an access probability factor. In order to avoid overloading the system with responses to the control message, MSs maintaining an active connection ignore (506, 508) the control message while idle mode MSs determine (506, 512) whether to respond based on the access probability factor. The system compares (310) a number of received responses to a threshold and determines whether to establish a point-to-multipoint communication (312) or a point-to-point communication (322) based on the comparison. The system also adjusts (314, 330) the access probability factor based on the number of responses.

摘要： A system and method for enhancing service over a high-speed downlink packet access (HSDPA) service in a cellular communication network includes informing a UE of the cells in an HSDPA active subset of cells. The US makes a measurement of the cells and selects a best cell for switching. The UE determines whether the best cell is an intra-node B cell or inter-node B cell with the serving cell from the network. If the best cell is an intra-node B cell, the UE signals the node B of the best cell, the node B switches to the best cell directly and UE receives the data from the target cell directly, and then Node B reports the switch to a radio network controller (RNC) that completes the final switching to the best cell by the RNC. If the best cell is an inter-node B cell, the UE signals the RNC of the best cell directly, whereupon the RNC sends the UE an acknowledgment without waiting for the completeness of the network configurations. The RNC re-routes data to the best cell, and the UE switches to the best cell after receiving the acknowledgment.
摘要翻译：一种用于在蜂窝通信网络中通过高速下行链路分组接入（HSDPA）服务来增强业务的系统和方法包括向小区通知小区的HSDPA活动子集。美国测量单元格并选择最佳的单元进行切换。 UE确定最佳小区是否是来自网络的服务小区的节点内小区或节点间小区B小区。如果最佳小区是节点内B小区，则UE向最佳小区的节点B发信号，节点B直接切换到最佳小区，UE直接从目标小区接收数据，然后节点B报告交换机到由RNC完成到最佳小区的最终切换的无线网络控制器（RNC）。如果最佳小区是节点间小区，则UE直接向RNC发送最佳小区的RNC，由此RNC在不等待网络配置的完整性的情况下向UE发送确认。 RNC将数据重新路由到最佳小区，并且UE在接收到确认之后切换到最佳小区。

摘要： A communication system (100) determines whether to establish a point-to-point or point-to-multipoint communication for conveyance of Multimedia Broadcast Multicast Services (MBMS) data based on a number of user equipments (102-104) being serviced by the communication system for MBMS service. The system broadcasts an access probability factor (154) in a control message to the user equipments. For a large number of MBMS users being counted (158), the method will select a point-to-multipoint broadcast (160). If the number of user equipments being counted is relatively small, the access probability factor is modified by a ratio of the number of point-to-point connections over the point-to-multipoint connections over the number of users being counted (174). The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.
