Gateway arrangements for wireless communication networks
First Claim
1. A network controller computing system, comprising:
- serving gateway (SGW) control plane circuitry to virtualize control plane functions of an SGW in a wireless communication network;
packet data network gateway (PGW) control plane circuitry to virtualize control plane functions of a PGW in the wireless communication network;
first communication circuitry to establish a first secure communication link between the SGW control plane circuitry and an SGW user plane computing system that is to perform user plane functions of an SGW, wherein the SGW user plane computing system is different from the network controller computing system; and
second communication circuitry to establish a second secure communication link between the PGW control plane circuitry and a PGW user plane computing system that is to perform user plane functions of a PGW, wherein the PGW user plane computing system is different from the network controller computing system,wherein;
the first communication circuitry is to further transmit, following a first stage of an attach procedure, an update message to the SGW user plane computing system to update a user data general packet radio service tunneling protocol (GTP-U) tunnel endpoint identifier assigned to the SGW user plane computing system; and
the network controller computing system is to further transmit in an attach accept message or an initial context setup message, the GTP-U tunnel endpoint identifier assigned to the SGW user plane computing system to an access node.
