Redirection of traffic instance identification in a 5g sa core network

A session management function, comprising:

• one or more processors;
• one or more transceivers;
• and
• non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, at the session management function (SMF), a communication from a network function repository function (NRF) indicating that the SMF is a selected SMF by the NRF, wherein the communication includes a request for IPv4 packet data network type capabilities;
• querying an SMF status datastore for capabilities of the selected SMF;
• determining that the selected SMF is not capable of handling the IPV4 packet data network type;
• and
• transmitting to an AMF an identification of a capable SMF based on SMF status datastore information, the capable SMF having an associated UPF with an IPV4 lane capable of handling the IPv4 packet data network type.

A non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, at an access management function (AMF) of a 5G core network from a mobile device, a connection request comprising an indication of IPv4 packet data network type;
• transmitting, from the AMF to a network function repository function (NRF), an identification of a session management function (SMF);
• selecting, by the NRF, a selected SMF;
• querying an SMF status datastore for capabilities of the selected SMF;
• determining that the selected SMF is not capable of handling the IPV4 packet data network type;
• and
• transmitting to the AMF an identification of a capable SMF based on SMF status datastore information, the capable SMF having an associated UPF with an IPv4 lane capable of handling the IPv4 packet data network type.
