Abstract

A method of establishing communication links during a failure within a mobile communications network includes detecting disruptions in communications between a plurality of base stations and a plurality of mobile terminals. Survivability components are activated within the base station and the mobile terminal to operate in a survivability mode. The survivability mode enables communications and services to be provided by the surviving base stations to mobile terminals through activated survivability components. The alternate communication links may operate for as long as a disruption exists.

First claim

What is claimed is:

1. A system of base stations and mobile terminals distributed within a communications network, the system comprising:
a number of survivability components located with at least one base station, the number of survivability components configured to:
monitor communications within the communications network, and
perform functions of corresponding components within the communications network,
wherein one or more of the survivability components are further configured to monitor and cache network communications and traffic information before a network failure occurs, wherein the cached information is stored within a storage server of the at least one base station.

2. The system of claim 1 , wherein the survivability components include a detector configured to determine an existence of a communications disruption within the communications network.

3. The system of claim 1 , wherein the survivability components are located within at least one mobile terminal.

4. The system of claim 2 , wherein the survivability components include an operations controller configured to manage operations of the at least one base station with a base station manager component in the at least one base station.

5. The system of claim 2 , wherein the survivability components include a mobility and location controller comprising a mobility management entity and a visitor location register and home location register to identify locations of mobile terminals within a coverage area of a base station.

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

7. The system of claim 1 , wherein the survivability components include a S-Radio link configured to establish a communications link between base stations within the communications network.

8. The system of claim 4 , wherein the storage server is configured to provide local information and resources.

9. A base station of a communications network, the base station comprising:
survivability components configured to maintain operation of the base station during a network failure of the communications network,
wherein a number of the survivability components correspond to components within the communications network that perform a same function, and
wherein one or more of the survivability components are configured to monitor and cache network communications and traffic information before the network failure occurs, wherein the cached information is stored within a storage server or the base station.

10. The base station of claim 9 , wherein the survivability components comprise:
a detector configured to determine the existence of the network failure.

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

12. The base station of claim 9 , wherein each of the number of survivability component is configured to monitor its corresponding component within the communications network and cache information and activity of the corresponding component.

13. The base station of claim 9 , wherein the number of the survivability components are preloaded with information.

14. The base station of claim 13 , wherein a storage server is preloaded with information.

15. The base station of claim 13 , wherein at least one of an authenticator, mobility management entity, visitor location register and home location register is preloaded with information.

16. The base station of claim 9 , wherein the survivability components further comprise:
a S-Radio link configured to enable communication traffic between operational base stations.

17. The base station of claim 10 , wherein the survivability components further comprise:
an operations controller configured to enable operations of the base station in a survivability mode.

18. A method of operating a base station, the method comprising:
determining an existence of a communications failure;
responsive activating operations of survivability components in a number of base stations included in a communication network in response to determining the existence of the communications failure; and
retrieving network communications and traffic information cached within a storage server of the base station in response to the existence of the communications failure,
wherein the cached information is stored within the storage server prior to determining the existence of the communications failure.
