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.

Claims

1. A method of establishing an ad hoc cellular network having an ad hoc cellular base station comprising the steps of:

a. optimizing a data path wherein the optimizing further comprises;

i. receiving a first data packet from a user equipment at a first ad hoc cellular base station wherein the first ad hoc cellular base station includes a local gateway providing local wireless access;

ii. removing a first protocol header from the first data packet;

iii. storing the first protocol header in a memory;

iv. receiving a second data packet wherein the second data packet was sent from a second ad hoc node having processor with limited core network functionality stored thereon;

v. analyzing a plurality of data packet headers stored in the memory in order to determine which corresponds to the second data packet; and

vi. appending a second data packet header to the second data packet.

2. The method of claim 1 further comprising a local packet data network gateway (LGW).

3. The method of claim 1 further comprising establishing a closed network.

4. A method of integrating an ad hoc cellular base station into a fixed cellular network comprising the steps of:

a. optimizing a data path wherein the optimizing further comprises;

i. receiving a first data packet from a user equipment at a first ad hoc cellular base station wherein the first ad hoc cellular base station includes a local gateway providing local wireless access;

ii. removing a first protocol header from the first data packet;

iii. storing the first protocol header in a memory;

iv. receiving a second data packet wherein the second data packet was sent from a second ad hoc node having processor with limited core network functionality stored thereon;

v. analyzing a plurality of data packet headers stored in the memory in order to determine which corresponds to the second data packet; and

vi. appending a second data packet header to the second data packet.

5. The method of claim 4 further comprising a local packet data network gateway (LGW).
