Claim of US Patent No. 11,032,873

1. One or more non-transitory, computer-readable media having instructions that, when executed, cause a session management function (SMF) to:instantiate a target uplink classifier (T-ULCL);
establish a forwarding tunnel between the T-ULCL and a source uplink classifier (S-ULCL); and
configure the T-ULCL with packet filters to force uplink traffic from an existing session between a user equipment (UE) and a source application node in a source data network to be forwarded via the forwarding tunnel.
