Abstract

Systems, methods, apparatuses, and computer program products for policy control for broadcast sessions. One method may include receiving, by a multicast/broadcast session management function, at least one broadcast session creation request comprising at least one broadcast session indication associated with at least one policy control function. The multicast/broadcast session management function may receive at least one policy update from the at least one policy control function, and transmit at least one resource allocation request associated with at least one broadcast session transmission to at least one application management function.

First claim

I claim:

1 . A method, comprising:
receiving, by a multicast/broadcast session management function, at least one multicast/broadcast session creation request comprising at least one indication of policy authorization for a multicast/broadcast session, wherein the at least one indication of policy authorization comprises at least one indication that indicates whether a network exposure function or a multicast/broadcast service function will provide a policy authorization for the multicast/broadcast session; and requesting, by the multicast/broadcast session management function, in response to the at least one indication of policy authorization for the multicast/broadcast session, creation of a policy control session for the multicast/broadcast session from at least one policy control function.

2 . The method of claim 1 , further comprising:
deferring, by the multicast/broadcast session management function, in response to the at least one indication of policy authorization for the multicast/broadcast session, at least one resource allocation request associated with the multicast/broadcast session to at least one access and mobility management function until the reception of an update request in the policy control session; receiving, by the multicast/broadcast session management function, at least one policy update request in the policy control session from the at least one policy control function; and transmitting, by the multicast/broadcast session management function, in response to the at least one indication of policy authorization for the multicast/broadcast session and the at least one policy update request, at least one resource allocation request associated with at least one broadcast session to the at least one access and mobility management function.

3 . The method of claim 2 , wherein at least one resource allocation request associated with the at least one broadcast session is deferred in response to the determination that the multicast/broadcast session comprises a broadcast session; and
the at least one resource allocation request associated with at least one broadcast session to the at least one access and mobility management function is transmitted in response to the determination that the multicast/broadcast session comprises a broadcast session.

4 . A method, comprising:
receiving, by a network exposure function or a multicast/broadcast service function, at least one request to create a multicast/broadcast session; determining, by the network exposure function or the multicast/broadcast service function, whether to create a policy authorization session for the multicast/broadcast session; requesting, by the network exposure function or the multicast/broadcast service function, from at least one multicast/broadcast session management function, a creation of the multicast/broadcast session, wherein, in response to determining to create the policy authorization session, the request for creation of the multicast/broadcast session comprises at least one indication of policy authorization, wherein the at least one indication of policy authorization comprises at least one indication that indicates whether the network exposure function or the multicast/broadcast service function will provide a policy authorization for the multicast/broadcast session; and requesting, by the network exposure function or the multicast/broadcast service function, creation of the policy authorization session for the multicast/broadcast session from at least one policy control function.

5 . The method of claim 4 , wherein the determining, whether to create the policy authorization session for the multicast/broadcast session is based on at least one of:
configured information; or at least one description of the multicast/broadcast session in the received request to create the multicast/broadcast session.

6 . The method of claim 5 , wherein the configured information includes an indication whether to create a policy authorization for all multicast/broadcast sessions.

7 . The method of claim 4 , wherein the determining further comprises determining, by the network exposure function or the multicast/broadcast service function, to create the policy authorization session for the multicast/broadcast session in response to the description of the multicast/broadcast session in the received request to create the multicast/broadcast session, wherein the multicast/broadcast session comprises a plurality of data flows.

8 . The method of claim 4 , wherein the creation of the policy authorization session for the multicast/broadcast session is requested in response to the determining to create the policy authorization session.

9 . An apparatus comprising:
at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: receive at least one multicast/broadcast session creation request comprising at least one indication of policy authorization for a multicast/broadcast session, wherein the at least one indication of policy authorization comprises at least one indication that indicates whether a network exposure function or a multicast/broadcast service function will provide a policy authorization for the multicast/broadcast session; and request, in response to the at least one indication of policy authorization for the multicast/broadcast session, the creation of a policy control session for the multicast/broadcast session from at least one policy control function.

10 . The apparatus of claim 9 , wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the apparatus at least to:
defer, in response to the at least one indication of policy authorization for the multicast/broadcast session, at least one resource allocation request associated with the multicast/broadcast session to at least one access and mobility management function until the reception of an update request in the policy control session; receive at least one policy update request in the policy control session from the at least one policy control function; and transmit, in response to the at least one indication of policy authorization for the multicast/broadcast session and the at least one policy update request, at least one resource allocation request associated with at least one broadcast session to the at least one access and mobility management function.

11 . The apparatus of claim 10 , wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the apparatus at least to:
defer at least one resource allocation request associated with the at least one broadcast session in response to the determination that the multicast/broadcast session comprises a broadcast session; and transmit the at least one resource allocation request associated with at least one broadcast session in response to the determination that the multicast/broadcast session comprises a broadcast session and the at least one policy update request.

12 . The apparatus of claim 10 , wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the apparatus at least to:
request the creation of a policy authorization session for the multicast/broadcast session in response to the determining to create the policy authorization session.

13 . An apparatus comprising:
at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: receive at least one request to create a multicast/broa
