摘要： A communication system 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 being serviced by the communication system for MBMS service. The system broadcasts an access probability factor in a control message to the user equipments. For a large number of MBMS users being counted, the method will select a point-to-multipoint broadcast. 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. The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.

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： 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 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： A method for informing a relay node when to receive data. The method includes the relay node being informed of a fixed point in a subframe of data when an access node will begin transmitting relevant data over a physical downlink shared channel. The method further includes the relay node beginning to receive data at approximately the fixed point.

摘要： Methods and systems for managing Multimedia Broadcast Multicast Service (MBMS) service continuity include, with a source node in a communication system, providing an MBMS, processing an event that indicates that a User Equipment (UE) being serviced by the source node is to be transferred to one of a number of candidate nodes, receiving a congestion bit from each of the candidate nodes, and providing data to the UE that causes the UE to be serviced by a target node selected from the candidate nodes based at least in part on values of the congestion bits from each of the candidate nodes.
