IP multimedia subsystem and method for MBMS file repair using HTTP servers
First Claim
1. A user equipment (UE) comprising:
- a control module to;
determine that a media file, downloaded over a Multimedia Broadcast Multicast Service (MBMS) bearer from an Internet Protocol Multimedia Subsystem (IMS) network component, requires a file repair; and
a transmission and reception module to;
initiate a file repair session by sending a Session Initiation Protocol (SIP) re-invite request to the IMS network component;
receive a SIP response message from the IMS network component; and
send a HTTP request to a file repair server to repair the media file.

Abstract
Disclosed in some examples is a method of media repair in an IMS based network, the method includes communicating with an IMS network using SIP to setup a download session with a BMSC over a MBMS bearer; responsive to determining that one or more received encoding symbols of media downloaded using the established MBMS bearer cannot be decoded: requesting a file repair procedure from the IMS network component using a SIP re-invite request, the SIP re-invite request including an address of an HTTP repair server indicated by the IMS network component during the MBMS bearer setup; responsive to receiving a SIP acknowledgement indicating that the request was successful, requesting an HTTP connection with the HTTP server to re-download the one or more encoding symbols of the media that could not be decoded; and receiving the one or more encoding symbols from the HTTP server.
