Mission critical video identifier for mission critical video policies
A policy control function device receives, from a mission critical video (MCVideo) application function, a DIAMETER AA-Request (AAR) command. The DIAMETER AAR command comprise: an attribute value pair (AVP) comprising an MCVideo-identifier identifying an MCVideo service; and a quality of service (QoS) parameter indicating a QoS of the MCVideo service. A Diameter command comprising one or more QoS policies based on the MCVideo-identifier and the QoS parameter is sent to a network function.
1. A method comprising:
receiving, by a policy control function from a mission critical video (MCVideo) application function, a DIAMETER AA-Request (AAR) command comprising:
an attribute value pair (AVP) comprising an MCVideo-identifier identifying an MCVideo service; and
a quality of service (QoS) parameter indicating a QoS of the MCVideo service; and
sending, by the policy control function to a network function, a Diameter command comprising one or more QoS policies based on the MCVideo-identifier and the QoS parameter.
2. The method of claim 1 , wherein:
the DIAMETER AA-Request (AAR) command further comprises a priority of the MCVideo service; and
the one or more QoS policies are further based on the priority of the MCVideo service.
3. The method of claim 1 , further comprising enforcing, by the policy control function, the one or more QoS policies on a plurality of packets transmitted via an MCVideo bearer.
4. The method of claim 1 , further comprising establishing, for an MCVideo application, an MCVideo bearer for a mission critical video call among a plurality of wireless devices comprising:
a first wireless device; and
a second wireless device.
5. The method of claim 4 , further comprising modifying, by the MCVideo application function, a floor of a floor control from the first wireless device to the second wireless device for the mission critical video call.
6. The method of claim 5 , wherein the modifying the floor control is performed by the first wireless device in response to releasing the floor.
7. The method according to claim 1 , wherein the QoS parameter indicate a priority.
8. The method of claim 1 , wherein a session initiation protocol (SIP) Resource-Priority header field triggers the DIAMETER AAR command.
9. The method of claim 8 , wherein the SIP Resource-Priority header field indicates an emergency priority.
10. The method of claim 1 , wherein the MCVideo application function resides in at least one of:
a MCVideo application server; and
a proxy call session control function.
11. A policy control function device comprising:
one or more processors; and
memory storing instructions that, when executed, cause the policy control function device to:
receive, from a mission critical video (MCVideo) application function, a DIAMETER AA-Request (AAR) command comprising:
an attribute value pair (AVP) comprising an MCVideo-identifier identifying an MCVideo service; and
a quality of service (QoS) parameter indicating a QoS of the MCVideo service; and
send, to a network function, a Diameter command comprising one or more QoS policies based on the MCVideo-identifier and the QoS parameter.
12. The policy control function device of claim 11 , wherein:
the DIAMETER AA-Request (AAR) command further comprises a priority of the MCVideo service; and
the one or more QoS policies are further based on the priority of the MCVideo service.
13. The policy control function device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the policy control function device to enforce the one or more QoS policies on a plurality of packets transmitted via an MCVideo bearer.
14. The policy control function device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the policy control function device to establish, for an MCVideo application, an MCVideo bearer for a mission critical video call among a plurality of wireless devices comprising:
a first wireless device; and
a second wireless device.
15. The policy control function device of claim 14 , wherein the instructions, when executed by the one or more processors, further cause the policy control function device to modify, by the MCVideo application function, a floor of a floor control from the first wireless device to the second wireless device for the mission critical video call.
16. The policy control function device of claim 15 , wherein the modification of the floor control is performed by the first wireless device in response to releasing the floor.
17. The policy control function device according to claim 11 , wherein the QoS parameter indicate a priority.
18. The policy control function device of claim 11 , wherein a session initiation protocol (SIP) Resource-Priority header field triggers the DIAMETER AAR command.
19. The policy control function device of claim 18 , wherein the SIP Resource-Priority header field indicates an emergency priority.
20. A system comprising:
a mission critical video (MCVideo) application function device; and
a policy control function device comprising:
one or more processors; and
memory storing instructions that, when executed, cause the policy control function device to:
receive, from the MCVideo application function device, a DIAMETER AA-Request (AAR) command comprising:
an attribute value pair (AVP) comprising an MCVideo-identifier identifying an MCVideo service; and
a quality of service (QoS) parameter indicating a QoS of the MCVideo service; and
send, to a network function, a Diameter command comprising one or more QoS policies based on the MCVideo-identifier and the QoS parameter.
