Abstract
A network repository function (NRF) receives, from a session management function (SMF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel. The NRF determines, in response to the discovery request, a first UPF that supports the L2TP tunnel. The NRF transmits, to the SMF, a discovery response comprising an identity of the first UPF that supports the L2TP tunnel.
Claims20
A method comprising:
- receiving, by a network repository function (NRF) from a session management function (SMF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel;
- determining, by the NRF and in response to the discovery request, a first UPF that supports the L2TP tunnel;
- and
- transmitting, by the NRF to the SMF, a discovery response comprising an identity of the first UPF that supports the L2TP tunnel.
A network repository function (NRF) comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the NRF to:
- receive, from a session management function (SMF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel;
- determine, in response to the discovery request, a first UPF that supports the L2TP tunnel;
- and
- transmit, to the SMF, a discovery response comprising an identity of the first UPF that supports the L2TP tunnel.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause a network repository function (NRF) to:
- receive, from a session management function (SMF), a discovery request for at least one user plane function (UPF) that supports a layer 2 tunneling protocol (L2TP) tunnel;
- determine, in response to the discovery request, a first UPF that supports the L2TP tunnel;
- and
- transmit, to the SMF, a discovery response comprising an identity of the first UPF that supports the L2TP tunnel.
