Abstract

Embodiments related to gateway arrangements for wireless communication networks are disclosed herein. For example, in some embodiments, a network controller computing system may include serving gateway (SGW) control plane circuitry to virtualize control plane functions of an SGW, packet data network gateway (PGW) control plane circuitry to virtualize control plane functions of a PGW, 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, 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. Other embodiments may be disclosed and/or claimed.

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

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.

2. The network controller computing system of claim 1, wherein the network controller computing system is an evolved packet core controller.

3. The network controller computing system of claim 1, wherein communication between a mobility management entity of the wireless communication network and the SGW user plane computing system is via the SGW control plane circuitry of the network controller computing system.

4. The network controller computing system of claim 1, wherein the PGW user plane computing system is a first PGW user plane computing system, and further comprising a third secure communication link between the PGW control plane circuitry and a second PGW user plane computing system that is to perform user plane functions of a PGW, wherein the second PGW user plane computing system is different from the network controller computing system and from the first PGW user plane computing system.
