Charging control for standalone non-public network
A session management function (SMF) sends, to a policy control function (PCF), a policy request message comprising a network identifier for a non-public network (NPN) and a PLMN identifier for the NPN. The SMF receives, from the PCF, a policy response message comprising a charging control policy.
1. A method comprising:
sending, by a session management function (SMF) to a policy control function (PCF), a policy request message comprising:
a network identifier for a non-public network (NPN); and
a Public Land Mobile Network (PLMN) identifier for the NPN; and
receiving, by the SMF from the PCF, a policy response message comprising a charging control policy.
2. The method of claim 1 , wherein the NPN comprises a stand-alone NPN (SNPN).
3. The method of claim 1 , further comprising receiving, by the SMF from an access and mobility management function (AMF), a message comprising one or more of the network identifier and the PLMN identifier.
4. The method of claim 3 , wherein the message comprises at least one of: a data network name (DNN); a single network slice selection assistance information (S-NSSAI); and a packet data unit (PDU) session identifier.
5. The method of claim 3 , wherein the sending the policy request message is based on the receiving the message from the AMF.
6. The method of claim 1 , further comprising sending, by the SMF to a charging function, a charging data request message based on the policy response message.
7. The method of claim 6 , wherein the charging data request message comprises the PLMN identifier.
8. A session management function (SMF), comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the SMF to perform operations comprising:
sending, to a policy control function (PCF), a policy request message comprising:
a network identifier for a non-public network (NPN); and
a Public Land Mobile Network (PLMN) identifier for the NPN; and
receiving, by the SMF from the PCF, a policy response message comprising a charging control policy.
9. The SMF of claim 8 , wherein the NPN comprises a stand-alone NPN (SNPN).
10. The SMF of claim 8 , wherein the operations further comprise receiving, from an access and mobility management function (AMF), a message comprising one or more of the network identifier and the PLMN identifier.
11. The SMF of claim 10 , wherein the message comprises at least one of: a data network name (DNN); a single network slice selection assistance information (S-NSSAI); and a packet data unit (PDU) session identifier.
12. The SMF of claim 10 , wherein the sending the policy request message is based on the receiving the message from the AMF.
13. The SMF of claim 8 , wherein the operations further comprise sending, to a charging function, a charging data request message based on the policy response message.
14. The SMF of claim 13 , wherein the charging data request message comprises the PLMN identifier.
15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a session management function (SMF) to perform operations comprising:
sending, to a policy control function (PCF), a policy request message comprising:
a network identifier for a non-public network (NPN); and
a Public Land Mobile Network (PLMN) identifier for the NPN; and
receiving, by the SMF from the PCF, a policy response message comprising a charging control policy.
16. The computer-readable medium of claim 15 , wherein the NPN comprises a stand-alone NPN (SNPN).
17. The computer-readable medium of claim 15 , wherein the operations further comprise receiving, from an access and mobility management function (AMF), a message comprising one or more of the network identifier and the PLMN identifier.
18. The computer-readable medium of claim 17 , wherein the message comprises at least one of: a data network name (DNN); a single network slice selection assistance information (S-NSSAI); and a packet data unit (PDU) session identifier.
19. The computer-readable medium of claim 17 , wherein the sending the policy request message is based on the receiving the message from the AMF.
20. The computer-readable medium of claim 15 , wherein the operations further comprise sending, to a charging function, a charging data request message based on the policy response message.
