Abstract

Methods, systems, and computer readable media for providing mobile device connectivity are disclosed. A system includes a mobile gateway implemented on one or more processors. The mobile gateway includes an on-premises telecommunications network core configured for establishing mobile data sessions for mobile user devices and enabling communication between the mobile user devices through the on-premises telecommunications network core. The mobile gateway includes a software-defined wide-area network (SD-WAN) controller configured for establishing an SD-WAN overlay network for connecting the mobile user devices to an external telecommunications network.

First claim

What is claimed is:

1. A system for providing mobile device connectivity, the system comprising:
one or more processors;
memory storing executable instructions for the processors; and
a mobile gateway implemented on the one or more processors, wherein the mobile gateway comprises:
an on-premises telecommunications network core configured for establishing mobile data sessions for a plurality of mobile user devices and enabling communication between the mobile user devices through the on-premises telecommunications network core, wherein the on-premises telecommunications core comprises a 5G core comprising an access and mobility management function (AMF), a session management function (SMF), and a user plane function (UPF); and
a software-defined wide-area network (SD-WAN) controller configured for establishing an SD-WAN overlay network for connecting the mobile user devices to an external telecommunications network;

wherein the mobile gateway comprises a session border controller (SBC), and
wherein the SBC is configured for controlling telecommunications control plane signaling at an edge between an on-premises access network and a remote system comprising a centralized controller;
wherein the SD-WAN controller is configured for establishing a tunnel over a data communications network with a remote system comprising a services gateway, and wherein the mobile gateway is configured for exchanging controlling signaling with the remote system over the tunnel to establish the mobile data sessions;
wherein the mobile gateway is configured for providing quality of service (QoS) and route optimization for the mobile user devices using the SD-WAN overlay network, and wherein providing QoS and route optimization for the mobile user devices using the SD-WAN overlay network comprises prioritizing the mobile data sessions and re-routing the mobile data sessions over the SD-WAN overlay network to maintain QoS according to prioritizing the mobile data sessions; and
wherein the SD-WAN controller is configured to collaborate with the SMF to manage mobile connectivity control and policy.

2. The system of claim 1 , wherein the on-premises telecommunications core comprises a packet data network (PDN) gateway (PGW).

3. The system of claim 2 , wherein the on-premises telecommunications core comprises an evolved packet core (EPC) comprising a mobility management entity (MME), a serving gateway (SGW), a home subscriber server (HSS), and an access network discovery and selection function (ANDSF).

4. A method for providing mobile device connectivity, the method comprising:
at a mobile gateway implemented on one or more processors:
establishing, using an on-premises telecommunications network core of the mobile gateway, mobile data sessions for a plurality of mobile user devices and enabling communication between the mobile user devices through the on-premises telecommunications network core, wherein the on-premises telecommunications core comprises a 5G core comprising an access and mobility management function (AMF), a session management function (SMF), and a user plane function (UPF); and
establishing, using a software-defined wide-area network (SD-WAN) controller, an SD-WAN overlay network for connecting the mobile user devices to an external telecommunications network;
wherein the mobile gateway comprises a session border controller (SBC), and
wherein the SBC is configured for controlling telecommunications control plane signaling at an edge between an on-premises access network and a remote system comprising a centralized controller;
wherein the SD-WAN controller is configured for establishing a tunnel over a data communications network with a remote system comprising a services gateway, and wherein the mobile gateway is configured for exchanging controlling signaling with the remote system over the tunnel to establish the mobile data sessions;
wherein the mobile gateway is configured for providing quality of service (QoS) and route optimization for the mobile user devices using the SD-WAN overlay network, and wherein providing QoS and route optimization for the mobile user devices using the SD-WAN overlay network comprises prioritizing the mobile data sessions and re-routing the mobile data sessions over the SD-WAN overlay network to maintain QoS according to prioritizing the mobile data sessions; and
wherein the SD-WAN controller is configured to collaborate with the SMF to manage mobile connectivity control and policy.

5. The method of claim 4 , wherein the on-premises telecommunications core comprises a packet data network (PDN) gateway (PGW).

6. A non-transitory computer readable medium comprising computer executable instructions embodied in the non-transitory computer readable medium that when executed by at least one processor of at least one computer cause the at least one computer to perform steps comprising:
at a mobile gateway implemented on one or more processors:
establishing, using an on-premises telecommunications network core of the mobile gateway, mobile data sessions for a plurality of mobile user devices and enabling communication between the mobile user devices through the on-premises telecommunications network core, wherein the on-premises telecommunications core comprises a 5G core comprising an access and mobility management function (AMF), a session management function (SMF), and a user plane function (UPF); and
establishing, using a software-defined wide-area network (SD-WAN) controller, an SD-WAN overlay network for connecting the mobile user devices to an external telecommunications network;
wherein the mobile gateway comprises a session border controller (SBC), and
wherein the SBC is configured for controlling telecommunications control plane signaling at an edge between an on-premises access network and a remote system comprising a centralized controller;
wherein the SD-WAN controller is configured for establishing a tunnel over a data communications network with a remote system comprising a services gateway, and wherein the mobile gateway is configured for exchanging controlling signaling with the remote system over the tunnel to establish the mobile data sessions;
wherein the mobile gateway is configured for providing quality of service (QoS) and route optimization for the mobile user devices using the SD-WAN overlay network, and wherein providing QoS and route optimization for the mobile user devices using the SD-WAN overlay network comprises prioritizing the mobile data sessions and re-routing the mobile data sessions over the SD-WAN overlay network to maintain QoS according to prioritizing the mobile data sessions; and
wherein the SD-WAN controller is configured to collaborate with the SMF to manage mobile connectivity control and policy.
