IMS based P2P streaming and download services

摘要

Technology to provide P2P switching between HTTP based delivery of DASH formatted content to an MBMS download is disclosed. In an example, a host UE can include computer circuitry configured to: receive a session initiation protocol (SIP) termination message, from a service control function (SCF) module to terminate an SIP session for delivery of DASH based content to a mobile device; send a SIP acknowledgement message to the SCF to be forwarded to the mobile device; and establish a FLUTE protocol based MBMS download session between the mobile device and a BMSC.UPF module operating on the host mobile device for the MBMS download. Technology is also disclosed for P2P MBMS download via BMSC and file repair via an HTTP server using the switching.

1. A service control function (SCF) module operable to switch from a multimedia broadcast multicast services (MBMS) download to a hypertext transfer protocol (HTTP) based delivery of dynamic adaptive streaming over HTTP (DASH) formatted content, the SCF having one or more processors and memory configured to:
receive a session initiation protocol (SIP) re-invitation at a service control function (SCF) module from a mobile device while the mobile device is receiving an MBMS download in a content delivery session that includes DASH formatted content from a broadcast multicast service center user plane sub-function (BM-SC.UPF) module operating on a host wireless mobile user device; send a SIP invitation from the SCF module to an HTTP/SIP adapter operating on the host wireless mobile user device to select an HTTP server operating on the host wireless mobile user device for an HTTP-based delivery to the mobile device; receive a SIP acknowledgement at the SCF module from the HTTP/SIP adapter indicating a selection of the HTTP server on the host wireless mobile user device for the content delivery session; and forward the SIP acknowledgement to the mobile device indicating a switch to the HTTP server for the content delivery session.
