IP multimedia subsystem and method for MBMS file repair using HTTP servers
First Claim
1. An apparatus of a user equipment (UE), the apparatus comprising:
- processing circuitry; and
memory, the processing circuitry configured 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;
initiate a file repair session by sending a Session Initiation Protocol (SIP) re-invite request to the IMS network component; and
generate signaling to send a HTTP request to repair the media file to a file repair server identified in a SIP response message from the IMS network component,wherein the memory is configured to store the SIP re-invite request.

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.

10. An apparatus of an Internet Protocol Multimedia Subsystem (IMS) network component, the apparatus comprising:
-
processing circuitry; and
memory, the processing circuitry configured to;execute a service coordination function (SCF) configured to; receive a Session Initiation Protocol (SIP) re-invite request from a User Equipment (UE); determine that the SIP re-invite request includes a request for a file repair, the file received by the UE over a Multimedia Broadcast Multicast Service (MBMS) bearer; and send a SIP response message to the UE, the SIP response message including an address of a HTTP server to perform the file repair. - View Dependent Claims (11, 12, 13, 14, 15)

16. A non-transitory machine-readable medium that stores instructions which when performed by processing circuitry, cause the processing circuitry to perform operations comprising:
-
determining 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; initiating a file repair session by sending a Session Initiation Protocol (SIP) re-invite request to the IMS network component; and sending a HTTP request to repair the media file to a file repair server identified in a SIP response message from the IMS network component. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
