SUBSTANCE: method includes a service control function (SCF) module receiving a session initiation protocol (SIP) re-invitation while the mobile device is receiving a MBMS download in a content delivery session including DASH formatted content, wherein the SCF module can send a SIP invitation to an HTTP/SIP adapter to select an HTTP server for an HTTP-based delivery. The SCF module can receive a SIP acknowledgement from the HTTP/SIP adapter indicating a selection of the HTTP server for the content delivery session. The SCF module can forward the SIP acknowledgement to the mobile device indicating a switch to the HTTP server for the content delivery session.
EFFECT: providing a method for switching from a multimedia broadcast multicast services download to a hypertext transfer protocol (HTTP)-based delivery of dynamic adaptive streaming over HTTP (DASH) formatted content in an Internet protocol multimedia subsystem network.
