Claim 0:
1. An apparatus, comprising:
a processor configured to cause a serving gateway control-plane (SGW-C) system to:
transmit, to a serving gateway user-plane computing system (SGW-U), a request to get a user data general packet radio service tunneling protocol (GTP-U) tunnel endpoint identifier (TEID) of the SGW-U;
receive, from the SGW-U, a response including the GTP-U TEID of the SGW-U;
transmit, to a packet data network gateway control-plane computing system (PGW-C) a create session request message including the GTP-U TEID of the SGW-U;
receive, from the PGW-C, a create session response including the GTP-U TEID of a packet data network gateway user-plane computer system (PGW-U);
create one or more GTP user-plane tunnels; and
update the SGW-U with a plurality of GTP TEIDs that correspond to the one or more GTP user-plane tunnels.
