7. The method of claim 6 , wherein the base station element detects a failure at the other base station element by detecting an interruption in data flow from the other base station element.
8. The method of claim 1 , wherein the indication of a failure condition is received from at least one of the other base station element and a base station controller.
9. The method of claim 8 , wherein a failure indication associated with a wireless communication portion of the other base station element is received by the base station controller via a wireline connection to the other base station element.
10. The method of claim 8 , wherein a failure indication associated with a wireline communication portion of the other base station element is received by the base station controller via a wireless connection to the other base station element.
11. The method of claim 1 , wherein the method is adapted for use at each of a plurality of base station elements within a network, each base station element being associated with at least one other base station element.
12. The method of claim 1 , wherein the indication of a failure condition is received at the base station element via a communication channel associated with one of the other base station element and a network management system.
13. The method of claim 1 , wherein said base station element is associated with a plurality of other base station elements, said method further comprising:
at said base station, periodically polling said plurality of other base station elements to determine thereby whether a failure conditions exists.
14. A base station element comprising a processor configured for:
at the base station element, in response to an indication of a failure condition associated with another base station element serving a plurality of wireless terminals, performing a self-reconfiguration according to a reconfiguration solution;
said reconfiguration solution adapted to reconfigure the base station element to serve a portion of the plurality of wireless terminals, wherein the reconfiguration solution depends on a type of the failure condition;
at the base station element, upon completion of the self-reconfiguration, initiating communication with each of the portion of wireless terminals to provide thereby a respective continuity of service.
15. The base station element of claim 14 , wherein the self-reconfiguration comprises increasing a power level employed by the base station element for expanding a wireless coverage area of the base station element.
16. The base station element of claim 14 , wherein the self-reconfiguration comprises:
monitoring each of the plurality of wireless terminals for determining a direction of travel associated with each of the plurality of wireless terminals; and
selecting as said portion of the plurality of wireless terminals those wireless terminals for which the respective direction of travel is toward the base station element.
17. The base station element of claim 14 , wherein the base station element detects a failure at the other base station element by detecting an interruption in data flow from the other base station element.
18. The base station element of claim 14 , wherein the indication of a failure condition is received at the base station element via a communication channel associated with one of the other base station element and a network management system.
19. A tangible and non-transient computer readable storage medium storing instructions which, when executed by a computer, adapt the operation of the computer to provide a method, comprising:
at a base station element, in response to an indication of a failure condition associated with another base station element serving a plurality of wireless terminals, performing a self-reconfiguration according to a reconfiguration solution;
said reconfiguration solution adapted to reconfigure the base station element to serve a portion of the plurality of wireless terminals, wherein the reconfiguration solution depends on a type of the failure condition;
at the base station element, upon completion of the self-reconfiguration, initiating communication with each of the portion of wireless terminals to provide thereby a respective continuity of service.
20. A computer program product wherein computer instructions, when executed by a processor in a base station element, adapt the operation of the base station element to provide a method, comprising:
at a base station element, in response to an indication of a failure condition associated with another base station element serving a plurality of wireless terminals, performing a self-reconfiguration according to a reconfiguration solution;
said reconfiguration solution adapted to reconfigure the base station element to serve a portion of the plurality of wireless terminals, wherein the reconfiguration solution depends on a type of the failure condition;
