Dash-aware network application function (D-NAF)

At least one non-transitory machine readable storage medium having instructions embodied thereon for authenticating and authorizing a client to receive dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) content, the instructions when executed by one or more processors of a server performs the following:

• authenticating, at the server that includes a network application function (NAF), a client using a Generic Bootstrapping Architecture (GBA)-based authentication and authorization procedure;
• authorizing, at the server that includes the NAF, the client for access to dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) content subject to content-specific policy information using the GBA-based authentication and authorization procedure, wherein the content-specific policy information is for a specific bitrate or resolution of the DASH content;
• receive, using the NAF, DASH authentication information for the DASH content and a DASH content information location in a media presentation description (MPD), wherein the DASH authentication information includes a signature and an authentication key, and the DASH content information location includes a DASH content information uniform resource locator (URL);
• authorize, using the NAF, the client for access to the DASH content based upon the received DASH authentication information and the received DASH content information;
• delivering, from the server that includes the NAF, the DASH content to the client when the client is successfully authenticated and authorized using the GBA-based authentication and authorization procedure;
• and
• providing, from the server that includes the NAF, operator network authentication and authorization for a DASH service provider, wherein the NAF received the content-specific policy information from the DASH service provider.

A server that includes a network application function (NAF), the server comprising one or more processors and memory configured to:

• authenticate, using the NAF, a client using a Generic Bootstrapping Architecture (GBA)-based authentication and authorization procedure;
• authorize, using the NAF, the client for access to dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) content subject to content-specific policy information using the GBA-based authentication and authorization procedure, wherein the content-specific policy information is for a specific bitrate or resolution of the DASH content;
• receive DASH authentication information for the DASH content and a DASH content information location in a media presentation description (MPD), wherein the DASH authentication information includes a signature and an authentication key, and the DASH content information location includes a DASH content information uniform resource locator (URL);
• authorize, using the NAF, the client for access to the DASH content based upon the received DASH authentication information and the received DASH content information;
• deliver the DASH content to the client when the client is successfully authenticated and authorized via the NAF using the GBA-based authentication and authorization procedure;
• and
• provide operator network authentication and authorization for a DASH service provider, wherein the NAF receives the content-specific policy information from the DASH service provider.
