Abstract:
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.
