Abstract
A Public Land Mobile Network (PLMN) includes an Evolved Packet Data Gateway (ePDG) and a Non-Seamless Wireless Local Area Network (WLAN) Offload Function (NSWOF). The ePDG receives control plane (CP) and user plane (UP) traffic sent from a User Equipment device (UE) over a Non-Public Network (NPN). The NSWOF receives the CP traffic from the ePDG, translates the CP traffic to a Service-Based Interface (SBI) format of a Service-Based Architecture (SBA) of the PLMN, and sends the translated CP traffic to at least one Network Function (NF) in the PLMN for accessing a PLMN service provided by the at least one NF.
Claims20
A system within a Public Land Mobile Network (PLMN), comprising:
- an Evolved Packet Data Gateway (ePDG) configured to receive control plane (CP) and user plane (UP) traffic sent from a User Equipment device (UE) over a Non-Public Network (NPN);
- and
- a Non-Seamless Wireless Local Area Network (WLAN) Offload Function (NSWOF) configured to:
- receive the CP traffic from the ePDG,
- translate the CP traffic to a Service-Based Interface (SBI) format of a Service-Based Architecture (SBA) of the PLMN, and
- send the translated CP traffic to at least one Network Function (NF) in the PLMN for accessing a PLMN service provided by the at least one NF.
A method, comprising:
- receiving, by one or more processors in a Public Land Mobile Network (PLMN), control plane (CP) and user plane (UP) traffic sent from a User Equipment device (UE) over a Non-Public Network (NPN);
- translating, by the one or more processors, the CP traffic to a Service-Based Interface (SBI) format of a Service-Based Architecture (SBA) of the PLMN,
- sending, by the one or more processors, the translated CP traffic to at least one Network Function (NF) in the PLMN for accessing a PLMN service provided by the at least one NF;
- receiving, by the one or more processors, responsive CP traffic associated with the PLMN service provided by the at least one NF;
- translating, by the one or more processors, the responsive CP traffic to a first message format;
- and
- forwarding, by the one or more processors, the translated, responsive CP traffic to the NPN.
At least one non-transitory storage medium storing instructions executable by one or more network devices in a Public Land Mobile Network (PLMN), wherein execution of the instructions causes the one or more network devices to:
- receive control plane (CP) and user plane (UP) traffic sent from a User Equipment device (UE) over a Non-Public Network (NPN);
- translate the CP traffic to a Service-Based Interface (SBI) format of a Service-Based Architecture (SBA) of the PLMN,
- send the translated CP traffic to at least one Network Function (NF) in the PLMN for accessing a PLMN service provided by the at least one NF;
- receive responsive CP traffic associated with the PLMN service provided by the at least one NF;
- translate the responsive CP traffic to a first message format;
- and
- forward the translated, responsive CP traffic to the NPN.
