摘要： A compression context for a plurality of packets (130) is established with a receiving device (102b). Each of these packets is associated with one or more reliable multicast protocols. Such as the Layered Coding Transform (LCT) protocol, the Asynchronous Layered Coding (ALC) protocol, the FLUTE protocol, the MUPPET protocol, and the NACK-Oriented Reliable Multicast (NORM) protocol. Upon establishment of the compression context, a compressed packet is generated for one of the plurality of packets and transmitted to the receiving device. The compressed packet has a reduced number of bits in its header. Upon receipt, a decompresso (116) of the receiving device decompresses the compressed packet based on the compression context.
摘要翻译：用接收设备（102b）建立多个分组（130）的压缩上下文。这些分组中的每一个都与一个或多个可靠的多播协议相关联。例如分层编码转换（LCT）协议，异步分层编码（ALC）协议，FLUTE协议，MUPPET协议和面向NACK的可靠组播（NORM）协议。在建立压缩上下文时，为多个分组之一生成压缩分组，并发送给接收设备。压缩包在其头部中具有减少的比特数。在接收到接收设备的解压缩（116）时，基于压缩上下文对压缩分组进行解压缩。

摘要： An apparatus, system method, and computer program product that combine the attributes of ALC and NORM for communicating data between devices (1 and 5) on a network. A sending device (1) uses multiple data rates on different channels to reliably send data packets and receivers use NACKS to request retransmission of missing or mangled data from the sending device or other receiving devices on the network. The sending device (1) using an active ALC mechanism and the receiving devices use NACK and transmitting mechanisms for transmitting acknowledgements or data from the device. The sending and receiving devices (1 and 5) can be located in the same or in different networks for communicating data packets during a data transmission session.
摘要翻译：一种装置，系统方法和计算机程序产品，其组合了用于在网络上的设备（1和5）之间传送数据的ALC和NORM的属性。发送设备（1）在不同信道上使用多个数据速率可靠地发送数据分组，接收机使用NACK来请求从发送设备或网络上的其他接收设备重传丢失或丢失数据。使用活动ALC机制的发送设备（1）和接收设备使用NACK和从设备发送确认或数据的发送机制。发送和接收设备（1和5）可以位于相同或不同的网络中，以在数据传输会话期间传送数据分组。

摘要： The invention relates to signalling in broadcast and multicast environments. For a service in the broadcast is defined an indicator, which is formulated into a unique indicator. The indicator is mapped into one time-slot in a signalling channel. A notification relating to the service is transmitted during the said time-slot. The notification is used for enabling the receiver for receiving said service, wherein the receiver may be turned off at other times.

摘要： For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.
摘要翻译：对于关于即将到来的传输会话的接收设备的通知，传输会话中的各种可能类型的标识符之一的标识符被映射到传输会话标识符字段。该字段用于通知接收设备。此外，重复值被添加到传输会话标识符字段，其指示即将到来的传输会话是否为新的。此外，如果可以终止由传输会话标识符识别的传输会话中的数据的获取，则接收设备可以释放为特定传输会话标识符存储的上下文数据。

摘要： PROBLEM TO BE SOLVED: To provide a method, a system, a transmitter, a network element, a receiver and a software application improved for data packet transmission in a system capable of point-to-multipoint transmission.
SOLUTION: One or more data packets are transmitted from a transmitter to one or more receivers, at least at one specific receiver of the receivers, a reception of repair data packets is required, repair information is signaled to a repair server in order to trigger a transmission of the repair data packets, and the repair information comprises information related to the number of transmitted data packets correctly received at the specific receiver. The transmission of data packets may for instance be controlled by file delivery over a unidirectional transport protocol and the signaling of the repair information may for instance be controlled by a hypertext transfer protocol.

摘要： A method and system for performing multicast broadcast handover in a wireless data network are disclosed. Each cell broadcasts administrative announcements over a logical channel to mobile terminals. The announcements indicate which multicast broadcasts are available in specified cells, as well as connection information for each cell. The mobile terminals may tune to a multicast broadcast as defined by the administrative announcements. While tuned to the multicast, the mobile terminal continues to receive administrative announcements. As the broadcast fades out or is otherwise interrupted, the mobile terminal can retune to the same multicast broadcast in another cell, based on the cell connection information included in the previously received administrative announcements.

摘要： A method, system, device, and computer code product is disclosed in which a sender (10) transmits data to a plurality of receivers (20) via a point-to-multipoint session. The receiver sends data repair requests to the sender (10) requesting data expected but not received and the sender (10) retransmits the expected but not received data via the point-to-multipoint session. The sender (10) can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender (10) can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session.
