SYSTEM AND METHOD FOR OPTIMIZING DOWNLOAD USER SERVICE DELIVERY TO ROAMING CLIENTS

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.
