Abstract
A session management function (SMF) sends, to a network repository function (NRF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel. The SMF receives, from the NRF, a discovery response comprising an identity of a UPF that supports the L2TP tunnel. The SMF selects, based on the UPF supporting the L2TP tunnel, the UPF. The SMF sends, to the UPF, a session request message comprising tunnel information of the L2TP tunnel.

A method comprising:
- sending, by a session management function (SMF) to a network repository function (NRF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel;
- receiving, by the SMF from the NRF, a discovery response comprising an identity of a UPF that supports the L2TP tunnel;
- selecting, by the SMF and based on the UPF supporting the L2TP tunnel, the UPF;
- and
- sending, by the SMF to the UPF, a session request message comprising tunnel information of the L2TP tunnel.

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 network repository function (NRF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel;
- receiving, from the NRF, a discovery response comprising an identity of a UPF that supports the L2TP tunnel;
- selecting, based on the UPF supporting the L2TP tunnel, the UPF;
- and
- sending, to the UPF, a session request message comprising tunnel information of the L2TP tunnel.
