Problems solved by technology

However, the disadvantage of this first solution is that a limit / requirement has to be set for the time interval of the repair request which needs to be signaled to the receiver in the service announcement
Even adding these parameters to the request URL does not lead to a satisfactory solution, as the size of the request line increases significantly due to including the extra parameters
Furthermore, such solutions limit the available possibilities for implementing a repair server, where the repair server needs to maintain a list of all file download sessions that host a given file and that are used in each of these file download sessions different TOI values ​​for

Embodiment Construction

[0021] Various embodiments of the present invention improve the file repair functionality defined in the protocols and codecs that can be found in 3GPP TS 26.346 (available at www.3gpp.org / ftp / Specs / archive / 26_series / 26.346 / , which is hereby incorporated by reference in its entirety). Accordingly, various embodiments of the present invention can provide unambiguous identification of the version associated with the file for which a file repair request was initiated. Unambiguous identification of file versions is achieved by extending the repair request with information that can identify file versions globally and independently of file download sessions.

[0022]According to an exemplary embodiment of the present invention, the last modification date of a file may be used in conjunction with the URL of the file to identify the file and file version. According to another exemplary embodiment of the present invention, the hash value of the file may also be used in conjunction wi...

Abstract

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 valueof the file can be utilized in conjunction with the file's URL to identify the file and its version.

Description
