摘要： A system and method for providing improved session control in unicast ses sions such as FLUTE sessions. According to various embodiments, a series of new commands are defined that permit a receiver to perform actions such as r equest a list of files to be delivered, trigger the delivery of selected fil es, ask that certain files not be delivered, and others. As a result, the ba ndwidth usage between the sender and the receiver can be reduced, and the da ta flow between the devices can be optimized.

摘要： An improved system and method for scheduling Join or Leave operations in a MBMS system. When a Join operation or a Leave operation is initiated by user equipment, it is determined whether the current time is within a protection period. If the current time is within a protection period, a first random time is calculated and an operation message is scheduled for transmission at the first random time. If the current time is outside of a protection but within an allowed period, the operation message is scheduled for immediate transmission. If the current time is outside of a protection and outside of the allowed period, a second random time is calculated and the operation message is scheduled to be sent at the second random time.

摘要： Systems and methods applicable, for instance, in data delivery. For example a service operator server and/or other computer might act to determine which of point-to-point repair mode and point-to-multipoint repair mode should be employed in the case where one or more receivers do not correctly receive dispatched data. As another example, the service operator server and/or other computer might calculate one or more estimates, request one or more values from one or more repair servers, and/or provide to one or more repair servers one or more directives regarding repair mode to be employed.

摘要： Various embodiments of present invention relate to the synchronization of an SDP stream to the media stream. In various embodiments, the SDP-consuming application initiates a FLUTE receiver and retrieves new versions of the SDP file. The terminal also retrieves information from the RTCP layer about the current sender time. The sender time is indicated as an NTP timestamp in RTCP sender reports. The receiver indicates to the player that the new SDP file will be valid after some time period. Various embodiments of the present invention also cover the behavior of a terminal upon receiving an SDP update. Still further, various embodiments of the present invention provides for richer out-of-band ESG delivery than conventional systems, permitting more meaningful session updates.

摘要： A system and method for ensuring an improved transition at the application layer when distribution of media is changed from broadcast/multicast bearers to unicast bearers and vice versa. A mapping is defined between the timeline of a Packet-Switched Streaming Service (PSS) session and the Multimedia Broadcast Multicast Service (MBMS) session timeline. This mapping is used to enable the correct positioning of the stream in a PSS session by a PSS server after a handover has occurred. Broadcast multicast service center (BM-SC) signals can support various options for media playback after a MBMS-PSS handover in a PSS session description protocol (SDP) file or in the MBMS user service description (USD). In response, the client can signal its choice in the RTSP request that is sent when switching to the PSS session.

摘要： Apparatuses and methods may include receiving a data flow comprising a plurality of packets, identifying static data and dynamic data in packet headers of the plurality of packets, generating a plurality of protocol packets by removing the static data from the packet headers while retaining the dynamic data, generating signaling data based on the static data, and generating a transport stream comprising the signaling data and the protocol each data flow packets.

摘要： A system and method for providing MBMS content distribution using unicast bearers. According to various embodiments, MBMS download user services are delivered to pieces of user equipment by delivering a FLUTE file delivery table via an OMA Push message. One of a number of different additional actions may be used in the delivery of the MBMS download user services. These actions include (1) making a single HTTP GET request using simple URL-encoding format to retrieve all files of the FDT; (2) making a single HTTP GET request using "group" field of FDT in URL-encoding to retrieve a logical group of files of the FDT; (3) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (4) making serialized HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (5) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one logical group of files of the FDT; (6) making serialized HTTP GET requests where each HTTP GET request retrieves at least one logical group of files of the FDT; (7) delivering the serviceID of the MBMS user service in the above mentioned OMA PUSH message but not including the serviceID in the FLUTE FDT; (8) an HTTP request to de-register the MBMS UE from the BM-SC for stopping the unicast delivery of the MBMS download user service; and (9) delivering the FDT Instance ID of the FDT Instance in an OMA Push message.
