Methods of incorporating an ad hoc cellular network into a fixed cellular network
First Claim
1. A method of establishing an ad hoc cellular network having an ad hoc cellular base station comprising:
- establishing, at a first ad hoc cellular base station, a first connection with a core cellular network;
establishing, at a second ad hoc cellular base station, an inter-base station connection with the first ad hoc cellular base station for relaying traffic from the first and the second ad hoc cellular base stations to the core cellular network, thereby establishing an ad hoc cellular network;
establishing, at the second ad hoc cellular base station, a second connection with the core cellular network;
measuring, at the first ad hoc cellular base station, a quality of the first connection;
determining, at one of the first and the second ad hoc cellular base stations, if the quality of the first connection falls below a threshold parameter; and
terminating, at the first ad hoc cellular base station, the first connection in favor of the second connection if the quality of the first connection falls below the threshold parameter.

Abstract
In this invention, we disclose methods directed toward integrating an ad hoc cellular network into a fixed cellular network. The methods disclosed herein automate the creation and integration of these networks. In additional embodiments, we disclose methods for establishing a stand-alone, ad hoc cellular network. In either of these implementations, we integrate or establish an ad hoc cellular network using mobile ad hoc cellular base stations configured to transmit and receive over a variety of frequencies, protocols, and duplexing schemes. The methods flexibly and dynamically choose an access or backhaul configuration and radio characteristics to optimize network performance. Additional embodiments provide for enhancing an existing network'"'"'s coverage as needed, establishing a local network in the event of a loss of backhaul coverage to the core network, and providing local wireless access service within the ad hoc cellular network.

18. An ad hoc network system, comprising:
-
a first ad hoc cellular base station in communication with and operating as a gateway to a core network; and a second ad hoc cellular base station in communication with the first ad hoc cellular base station comprising; a core network wireless interface configured to connect to the core network; a Wi-Fi mesh networking interface configured to connect to the first ad hoc cellular base station; and a network processor coupled to the core network wireless interface and the Wi-Fi mesh networking interface, the network processor configured to; receive first connection quality information from the first ad hoc cellular base station, receive second connection quality information from the core network wireless interface, evaluate the first and the second connection quality information against a threshold parameter, and identify whether to use the first ad hoc cellular base station as the gateway to the core network, wherein the network processor is further configured to terminate a connection with the first ad hoc cellular base station in favor of the core network wireless interface to connect to the core network.
