Enhanced Software-Defined Network Controller to Support Ad-Hoc Radio Access Networks

A method comprising:

• receiving, by an ad-hoc radio access controller, an attach request from a device operating in communication with an ad-hoc radio access technology transceiver node served by the ad-hoc radio access controller, wherein the attach request comprises a physical IP address associated with the device, and wherein the physical IP address comprises an IP address sub-interface pre-fix broadcast to the device by the ad-hoc radio access technology transceiver node combined with a physical address of the device;
• in response to the attach request, completing, by the ad-hoc radio access controller, an attachment procedure for allowing the device to access an ad-hoc radio access network comprising the ad-hoc radio access technology transceiver node;
• assigning, by the ad-hoc radio access controller, a local private IP address to the device;
• providing, by the ad-hoc radio access controller, on behalf of the device, the attach request to a software-defined networking (“SDN”) controller, wherein the SDN controller completes attachment for allowing the device access to an SDN network via the ad-hoc radio access network;
• receiving, by the ad-hoc radio access controller, from the SDN controller, notification of attachment success;
• receiving, by the ad-hoc radio access controller, from the SDN controller, an address of a preferred dynamic host configuration protocol server;
• requesting, by the ad-hoc radio access controller, from the SDN controller, a public session layer IP address from the preferred dynamic host configuration protocol server;
• receiving, by the ad-hoc radio access controller, from the preferred dynamic host configuration protocol server, the public session layer IP address;
• and
• informing, by the ad-hoc radio access controller, the SDN controller of an association between the public session layer IP address and the physical IP address, wherein the SDN controller updates a component operating within the SDN network to reflect how to reach the device via the public session layer IP address through the ad-hoc radio access controller with the IP address sub-interface pre-fix.

An ad-hoc radio access controller comprising:

• a processor;
• and
• memory that stores instructions that, when executed by the processor, cause the processor to perform operations comprising
• receiving an attach request from a device operating in communication with an ad-hoc radio access technology transceiver node served by the ad-hoc radio access controller, wherein the attach request comprises a physical IP address associated with the device, and wherein the physical IP address comprises an IP address sub-interface pre-fix broadcast to the device by the ad-hoc radio access technology transceiver node combined with a physical address of the device,
• in response to the attach request, completing an attachment procedure for allowing the device to access an ad-hoc radio access network comprising the ad-hoc radio access technology transceiver node,
• assigning a local private IP address to the device,
• providing, on behalf of the device, the attach request to a software-defined networking (“SDN”) controller, wherein the SDN controller completes attachment for allowing the device access to an SDN network via the ad-hoc radio access network,
• receiving, from the SDN controller, notification of attachment success,
• receiving, from the SDN controller, an address of a preferred dynamic host configuration protocol server,
• requesting, from the SDN controller, a public session layer IP address from the preferred dynamic host configuration protocol server,
• receiving, from the preferred dynamic host configuration protocol server, the public session layer IP address, and
• informing the SDN controller of an association between the public session layer IP address and the physical IP address, wherein the SDN controller updates a component operating within the SDN network to reflect how to reach the device via the public session layer IP address through the ad-hoc radio access controller with the IP address sub-interface pre-fix.
