| 20080222300 | METHOD AND APPARATUS FOR SYNCHRONIZING NOTIFICATION MESSAGES - Various embodiments provide for the splitting of a notification message to a user, where the notification message enables at least one of interactivity and delivery of information associated with a media broadcast service. A first component of the notification message carries media content and is transmitted utilizing a file delivery protocol, such as FLUTE, HTTP, and OMA-PUSH. A second component of the notification message carries any synchronization information associated with the interactivity and the delivery of the information associated with the media broadcast service. The second component of the notification message can be transported in an RTP payload via RTP to allow for accurate synchronization of the notification message with a media stream of the media broadcast service containing the media content. | 09-11-2008 |

Similar to deterministic multiplexing, aspects of the invention split the multiplex into several time-cycles and allocate, for each service, a time slot (data burst) from the total time-cycle according to the service's average bit rate. In accordance with aspects of the invention, however, the boundaries of each data burst are allowed to grow or shrink by a limited amount. | 12-04-2008 |

| 20080307041 | SYSTEM AND METHOD FOR IMPLEMENTING MBMS HANDOVER DURING DOWNLOADED DELIVERY - An improved system and method for implementing Multimedia Broadcast/Multicast Service (MBMS) handover during download delivery. Various embodiments of the present invention involve the use of the HTTP/1.1 “chunked” mode to deliver updates of the file delivery table (FDT) of a session in a push-like mode. In order to allow for push delivery of the contents of a FLUTE session, each FDT instance is encoded as one part of a multipart MIME message and is sent as a separate chunk. The receiver can interpret each of the separate chunks to extract the FDT instance from the chunks. The content type of each part of the message is set to “text/xml” or another MIMI type in order to indicate that the content is an FDT instance. After parsing the FDT instance and updating the FDT, the receiver is able to identify which files of the session are of interest and can perform a HTTP GET request to retrieve a specific file. | 12-11-2008 |
| 20080313191 | METHOD FOR THE SUPPORT OF FILE VERSIONING IN FILE REPAIR - A system and method are provided for changing the file repair functionality associated with MBMS systems in order to allow for the unambiguous identification of a file version in the file repair request. A file repair request is extended by information that can globally, and independently of the file download session, identify the version of a file. According to one embodiment of the present invention, a last modification date of a file can be utilized in conjunction with the file's URL to identify the file and its version. According to another embodiment of the present invention, a hash value of the file can be utilized in conjunction with the file's URL to identify the file and its version. | 12-18-2008 |

This system and method is forward-compatible and allows for legacy terminals to detect if a new feature, introduced in later releases, is required for the consumption of the service. If a required feature is not supported, then the terminal will not attempt to join the session. The service announcement or service discovery carries information about the requirements for the MBMS user service. Any requirement that is not understood by the terminal indicates to the terminal that it cannot correctly receive and decode the service. | 12-25-2008 |

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. | 03-19-2009 |
| 20090110132 | SYSTEM AND METHOD FOR RE-SYNCHRONIZATION OF A PSS SESSION TO AN MBMS SESSION - An accurate indication of a re-synchronization point/time in streamed media content is provided to allow playout of the streamed media content from or at a desired point/time when a client or receiver switches from multimedia broadcast multicast service (MBMS) to packet switch stream (PSS) service. Various parameters, e.g., synchronization source (SSRC) and real-time protocol (RTP) timestamp, of a last received media RTP packet is signaled to a receiver. Alternatively, the SSRC and sequence number of the last received media RTP packet is signaled to the receiver, or the SSRC, the RTP timestamp, and the sequence number of the last received media RTP packet is signaled to the receiver. Also, a UTC clock time can be calculated based upon the last received real-time control protocol (RTCP) sender report (SR) and the timestamp of the last received media RTP packet in order to effectuate proper synchronization between MBMS and PSS servers. | 04-30-2009 |
| 20090113471 | METHOD AND APPARATUS FOR SIGNALING UPDATES TO NOTIFICATION SESSION IN IP DATACAST - Systems and methods of signaling changes and updates associated with the default notification channels in a non-time sliced way are provided. A default notification channel event is signaled to a terminal. The signaling includes a reference to the relevant default notification channel, a timestamp, and/or a version number/counter. A comparison is made between a stored timestamp and/or version number/counter with the timestamp and/or version number/counter indicated in the signaling. A more recent timestamp and/or version number/counter prompts the terminal to tune in to the default notification channel to process the default notification channel event. The signaling can be performed using Program Specific Information/Service Information (PSI/SI), which is non-time-sliced and is received by all terminals. Additionally, the PSI/SI signaling is effectuated by creating descriptors in existing notification/network information tables and/or by creating a dedicated notification signaling table. | 04-30-2009 |
| 20090122740 | SYSTEM AND METHOD FOR SIGNALING AVAILABILITY OF AN MBMS USER SERVICE IN MULTIPLE VARIANTS - A system and method for signaling the availability of a Multimedia Broadcast/Multicast Service (MBMS) user service in multiple variants. Various embodiments involve the usage of the additional capacity introduced by MBMS Over a Single Frequency Network (MBSFN) in order to carry a higher quality or more robust variant of the service in MBMS. The broadcast multicast service center (BM-SC) provides the same MBMS user service in two variants, one for the regular MBMS and the other for MBSFN. The MBSFN variant of the service may be charged differently and would then need to be protected separately. In various embodiments, the user equipment is informed that the same service is present in different variants and therefore can then select one of the available variants for consumption. | 05-14-2009 |

The first-level filtering information may be separate of the transport object. If the transport object is not discarded after first-level filtering, then the second-level filtering information, which requires the processing of the transport object, is used to fetch the messages in the bundle. | 08-20-2009 |
