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.

A “Media Identifier” operates on concurrent media streams to provide large numbers of clients with real-time server-side identification of media objects embedded in streaming media, such as radio, television, or Internet broadcasts. Such media objects may include songs, commercials, jingles, station identifiers, etc. Identification of the media objects is provided to clients by comparing client-generated traces computed from media stream samples to a large database of stored, pre-computed traces (i.e., “fingerprints”) of known identification. Further, given a finite number of media streams and a much larger number of clients, many of the traces sent to the server are likely to be almost identical. Therefore, a searchable dynamic trace cache is used to limit the database queries necessary to identify particular traces. This trace cache caches only one copy of recent traces along with the database search results, either positive or negative. Cache entries are then removed as they age.

The equipment comprises transmit equipment and receive equipment. The transmit equipment contains an aggregator that combines a plurality of packets based on user service requirements. The packets to be transmitted are retrieved at the fixed rate of the time delay-intolerant information. The size of the aggregate packet can be determined on a static or dynamic basis. The receiving equipment contains a de-aggregator circuit that receives aggregated packets and generates individual packets from the received aggregated packet. The generated individual packets are retrieved from the de-aggregator at the fixed rate of the time delay-intolerant information.

A method and system for reducing delay in wireless communications by use of a burst based access and assignment system.

The method concerns multicast service delivering through the UMTS and GSM networks. For this aim is given higher priority to an opportune subset of all the real-time services with guaranteed bandwidth transmissible by the network. This subset is named IS-MBMS (Immediate Streaming-Multimedia Broadcast Multicast Service). A certain amount of physical resources is reserved in all the system for the IS-MBMS services; not real-time services can be transmitted on the reserved resources when not used by the IS-MBMS ones. The reserved resources allow for transmitting the IS-MBMS services with minimum bit-rate, at least. The network announces in the service area that an IS-MBMS content becomes available; in reply one or more subscribed users transmit a request for joining a multicast group for that service. The network transmits a notification message on a multicast channel to give to the joined users useful information of how get the announced service, i.e.: Service-Id, RB parameters, etc. The IS-MBMS content is transmitted immediately on a point-to-multipoint channel set-up in each involved cells, even if there are zero recipients in the cell. Content is transmitted in parallel in different cells, leading to service continuity, and the mobile station can perform soft combining. During the IS-MBMS content delivery the network can count in each involved cell the number of subscribed users joined to the transmitted IS-MBMS service. The network switches from point-to-multipoint to point-to-point or to no transmission depending on the result of counting and on a fixed threshold. Alternatively the network, parallel to the content delivery, can execute a checking procedure to see if there are joined users in a cell: in this case the point-to-multipoint channel is switched to no transmission (fig. 3).
