End-to-end resource prioritization for a multimedia priority service on-demand service user

A system for facilitating an on-demand multimedia priority service (MPS) for a data transport services (DTS) session in a radio access network (RAN), comprising:

• a processor;
• and
• a memory device that contains instructions that are readable by said processor to cause said processor to perform operations of:
• sending, by a Policy Control Function (PCF) to a Session Management Function (SMF), an MPS On-Demand indication;
• receiving, at said SMF, said MPS On-Demand indication;
• and
• sending said MPS On-Demand indication from said SMF to an Access and Mobility Management Function (AMF),
• wherein said AMF, in response to receiving said MPS On-Demand indication, sends, to user equipment (UE), an MPS indicator in downlink Non-Access Stratum (NAS) messaging to indicate said UE may use MPS;
• wherein said SMF excludes said session from congestion controls that reduce services offered to non-MPS sessions;
• and
• wherein said AMF, in response to receiving said MPS On-Demand indication, also triggers a release of a non-MPS session.

A non-transitory storage device for facilitating an on-demand multimedia priority service (MPS) for a data transport services (DTS) session in a radio access network (RAN), wherein said storage device comprises instructions that are readable by a processor to cause said processor to perform operations of:

• sending, by a Policy Control Function (PCF) to a Session Management Function (SMF), an MPS On-Demand indication;
• receiving, at said SMF, an MPS On-Demand indication;
• and
• sending said MPS On-Demand indication from said SMF to an Access and Mobility Management Function (AMF),
• wherein said AMF, in response to receiving said MPS On-Demand indication, sends, to user equipment (UE), an MPS indicator in downlink Non-Access Stratum (NAS) messaging to indicate said UE may use MPS;
• wherein said SMF excludes said session from congestion controls that reduce services offered to non-MPS sessions;
• and
• wherein said AMF, in response to receiving said MPS On-Demand indication, also triggers a release of a non-MPS session.
