Survivable mobile network system

1. A mobile terminal comprising:

one or more survivability components configured to:

monitor communications within a communications network;

cache network communications and traffic information before a network failure occurs, wherein the one or more survivability components store the cached network communications and traffic information in at least one storage device within the mobile terminal; and

upon a network failure, perform a same function as one or more components within the communications network using the cached network communications and traffic information,

wherein the one or more survivability components are configured to activate a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the mobile terminal to consume less power and radio resources than consumed when the survivability mode is inactive.

2. The mobile terminal of claim 1 , wherein the one or more survivability components include a detector configured to determine an existence of a communications disruption within the communications network.

3. The mobile terminal of claim 2 , wherein the survivability components include an operations controller configured to manage operations with a base station manager component in at least one base station in the communications network.

4. The mobile terminal of claim 2 , wherein the survivability components include a mobility and location controller comprising a mobility management entity (MME) and a visitor location register and home location register (VLR/HLR), wherein the MME and VLR/HLR enable the mobile terminal to identify locations of mobile terminals within a coverage area of a base station.

5. The mobile terminal of claim 2 , wherein the survivability components include an authenticator, and wherein the mobile terminal is configured to utilize the authenticator to provide authentication and authorization processes to mobile terminals in a surviving area.

6. The mobile terminal of claim 1 , wherein the one or more survivability components include an S-Radio link configured to establish a communications link between base stations within the communications network.

7. The mobile terminal of claim 1 , wherein the one or more survivability components are configured to receive local information and resources from a storage server during an emergency.

8. A base station of a communications network, the base station comprising:

one or more survivability components configured to:

monitor communications within the communications network;

cache network communications and traffic information within a storage server located on the base station before a network failure occurs;

upon a network failure, perform a same function as one or more components within the communications network using the cached network communications and traffic information; and

activate a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the base station to consume less power and radio resources than consumed when the survivability mode is inactive.

9. The base station of claim 8 , wherein the one or more survivability components comprise a detector configured to determine the existence of the network failure.

10. The base station of claim 9 , wherein the detector is further configured to activate operations of the one or more survivability components at the base station.

11. The base station of claim 8 , wherein each survivability component is configured to monitor its corresponding component within the communications network and cache information and activity of the corresponding component.

12. The base station of claim 8 , wherein the one or more survivability components are preloaded with information that enables the base station to authenticate and manage mobile terminals operating in the survivability mode during the network failure.

13. The base station of claim 12 , wherein the storage server is preloaded with information.

14. The base station of claim 8 , wherein the one or more survivability components perform, during the network failure, at least one function that would otherwise be performed by a mobility management entity (MME), a visitor location register (VLR) and/or a home location register (HLR).

15. The base station of claim 8 , wherein the one or more survivability components comprise an S-Radio link configured to enable communication traffic between operational base stations.

16. A method of operating a base station, the method comprising:

monitoring communications within a communications network;

caching network communications and traffic information within a storage server located on the base station before a network failure occurs;

upon a network failure, performing, by the base station, a same function as one or more components within the communications network using the cached network communications and traffic information; and

activating a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the base station to consume less power and radio resources than consumed when the survivability mode is inactive.

17. The method of claim 16 , further comprising activating operations of survivability components in a number of base stations in the communication network in response to detecting the network failure, wherein activating operations of the survivability components cause the base stations to perform functions that would otherwise be performed by a mobility management entity (MME), a visitor location register (VLR) and/or a home location register (HLR).

18. The method of claim 16 , further comprising using an S-Radio link to enable communication between operational base stations during the network failure.
