Restricted service type for restricted local operator services in a wireless network
An session management function (SMF) receives, from an access and mobility management function, a packet data unit (PDU) session request message comprising: a first parameter indicating a restricted service type for restricted local operator services (RLOS); and a second parameter indicating a network slice selection assistance information (NSSAI) for the RLOS. A policy request comprising the first parameter and the second parameter is sent to a policy control function (PCF). A policy response comprising a policy and charging rule for the RLOS is received from the PCF.
1. A method comprising:
receiving, by a session management function (SMF) from an access and mobility management function, a packet data unit (PDU) session request message comprising:
a first parameter indicating a restricted service type for restricted local operator services (RLOS); and
a second parameter indicating a network slice selection assistance information (NSSAI) for the RLOS;
sending, by the SMF to a policy control function (PCF), a policy request comprising the first parameter and the second parameter; and
receiving, by the SMF from the PCF, a policy response comprising a policy and charging rule for the RLOS.
2. The method of claim 1 , wherein the policy and charging rule is based on the first parameter and the second parameter.
3. The method of claim 1 , further comprising sending, by the SMF to a user plane function, the policy and charging rule.
4. The method of claim 1 , wherein the PDU session request message further comprises at least one of:
a third parameter indicating a data network name (DNN) for the RLOS; or
a fourth parameter indicating an identifier of a wireless device.
5. The method of claim 4 , wherein the policy request further comprises the third parameter and the fourth parameter.
6. The method of claim 4 , wherein the policy and charging rule is further based on the third parameter and the fourth parameter.
7. The method of claim 1 , wherein the policy and charging rule for the RLOS comprises at least one of:
a redirect policy;
a gating policy;
a quality of service (QoS) policy; or
a charging policy.
8. The method of claim 1 , wherein the policy response further comprises a restricted local operator service information.
9. The method of claim 8 , wherein the restricted local operator service information comprises at least one of:
a service type of one of the RLOS; or
application information associated with the service type.
10. The method of claim 1 , further comprising selecting, by the SMF and based on the restricted service type, a user plane function.
11. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause a session management function (SMF) to:
receive, from an access and mobility management function, a packet data unit (PDU) session request message comprising:
a first parameter indicating a restricted service type for restricted local operator services (RLOS); and
a second parameter indicating a network slice selection assistance information (NSSAI) for the RLOS;
send, to a policy control function (PCF), a policy request comprising the first parameter and the second parameter; and
receive, from the PCF, a policy response comprising a policy and charging rule for the RLOS.
12. The apparatus of claim 11 , wherein the policy and charging rule is based on the first parameter and the second parameter.
13. The apparatus of claim 11 , further comprising sending, by the SMF to a user plane function, the policy and charging rule.
14. The apparatus of claim 11 , wherein the PDU session request message further comprises at least one of:
a third parameter indicating a data network name (DNN) for the RLOS; or
a fourth parameter indicating an identifier of a wireless device.
15. The apparatus of claim 14 , wherein the policy request further comprises the third parameter and the fourth parameter.
16. The apparatus of claim 14 , wherein the policy and charging rule is further based on the third parameter and the fourth parameter.
17. The apparatus of claim 11 , wherein the policy and charging rule for the RLOS comprises at least one of:
a redirect policy;
a gating policy;
a quality of service (QoS) policy; or
a charging policy.
18. The apparatus of claim 11 , wherein the policy response further comprises a restricted local operator service information.
19. The apparatus of claim 18 , wherein the restricted local operator service information comprises at least one of:
a service type of one of the RLOS; or
application information associated with the service type.
20. A system comprising:
an access and mobility management function (AMF);
a policy control function (PCF); and
an session management function (SMF) comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause a session management function (SMF) to:
receive, from the AMF, a packet data unit (PDU) session request message comprising:
a first parameter indicating a restricted service type for restricted local operator services (RLOS); and
a second parameter indicating a network slice selection assistance information (NSSAI) for the RLOS;
send, to the PCF, a policy request comprising the first parameter and the second parameter; and
receive, from the PCF, a policy response comprising a policy and charging rule for the RLOS.
