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 the steps of:
- a. analyzing a speed to determine a mobility state of an ad hoc cellular base station;
b. querying a local or remote cache stored in a computing server to determine a backhaul configuration or an access configuration for the ad hoc cellular base station;
c. receiving the backhaul configuration or the access configuration for the ad hoc cellular base station from the local or remote cache;
d. evaluating an operational parameter of a neighboring cellular base station;
e. determining if the access configuration or backhaul configuration should be updated based on the operational parameter; and
f. transmitting or receiving an access signal or a backhaul signal using the access configuration or the backhaul configuration.

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.
