Abstract

Communication between base station controllers and a mobile switching center may be provided by a consolidating device that operates between the BSCs and the MSCs. One example method of operation may include initiating an active process on an active network device and a standby process on a redundant network device configured as a backup to the active network device. Other operations may include receiving a data message from at least one base station controller on the active network device, and detecting a communication failure by at least one of the active process and the standby process, in response to the received data message. Other operations may include automatically configuring the redundant network device to become the active network device.

Claims

1. A method of communicating between a plurality of base station controllers and at least one mobile switching center, the method comprising:

initiating an active process on an active Internet Protocol Signaling Concentrator (IPSC) and a standby process on a redundant (IPSC) configured as a backup to the active (IPSC), the active (IPSC) and the redundant (IPSC) intermediate the plurality of base station controllers and the at least one mobile switching center;

receiving a data message from at least one of the plurality of base station controllers on the active (IPSC);

detecting a communication failure by at least one of the active process and the standby process, in response to the received data message; and

automatically configuring the redundant (IPSC) to become the active (IPSC).

2. The method of claim 1, wherein the data message is destined for the at least one mobile switching center.

3. The method of claim 1, further comprising:

allocating a port on the active (IPSC) for the at least one base station controller that transmitted the data message and forwarding the data message from the active (IPSC) to the at least one mobile switching center.

4. The method of claim 1, further comprising:

determining that the failure occurred while being processed by the active process.

5. The method of claim 1, further comprising:

disconnecting all active calls being processed by the plurality of base station controllers as a result of the communication failure being detected.

6. The method of claim 1, wherein the communication failure is detected by the active (IPSC), and wherein the communication failure is determined to be a lack of communication with the at least one mobile switching center.

7. The method of claim 1, further comprising:

upon detection of the communication failure, shutting down the active (IPSC) and restarting the active (IPSC), and during the shutting down and restarting operations, the redundant (IPSC) takes over the role as the new active (IPSC) and the active (IPSC) takes over the role as the new redundant (IPSC).

8. An apparatus configured as an Internet Protocol Signaling Concentrator (IPSC) to communicate between a plurality of base station controllers and at least one mobile switching center, the apparatus comprising:

a processor configured to initiate an active process on the apparatus and a standby process on a redundant (IPSC) configured as a backup to the apparatus, the apparatus and the redundant (IPSC) intermediate the plurality of base station controllers and the at least one mobile switching center; and

a receiver configured to receive a data message from at least one of the plurality of base station controllers, wherein the processor is further configured to detect a communication failure by at least one of the active process and the standby process, in response to the received data message, and automatically configure the redundant (IPSC) to become an active (IPSC).

9. The apparatus of claim 8, wherein the data message is destined for the at least one mobile switching center.

10. The apparatus of claim 8, wherein the processor is further configured to allocate a port on the apparatus for the at least one base station controller that transmitted the data message, and further comprising a transmitter that is configured to forward the data message to the at least one mobile switching center.

11. The apparatus of claim 8, wherein the processor is further configured to determine that the failure occurred while being processed by the active process.

12. The apparatus of claim 8, wherein the processor is further configured to disconnect all active calls being handled from the plurality of base station controllers as a result of the communication failure being detected.

13. The apparatus of claim 8, wherein the communication failure is detected by the apparatus, and wherein the communication failure is determined to be a lack of communication with the at least one mobile switching center.

14. The apparatus of claim 8, wherein upon detection of the communication failure, the processor is further configured to shut down the apparatus and restart the apparatus, and during the shutting down and restarting operations, the redundant (IPSC) takes over the role as the new active (IPSC) and the apparatus takes over the role as the new redundant (IPSC).

15. A non-transitory computer readable storage medium configured to store instructions that when executed by a processor cause the processor to perform communications between a plurality of base station controllers and at least one mobile switching center, the processor being further configured to perform:

initiating an active process on an active Internet Protocol Signaling Concentrator (IPSC) and a standby process on a redundant (IPSC) configured as a backup to the active (IPSC), the apparatus and the redundant (IPSC) intermediate the plurality of base station controllers and the at least one mobile switching center;

receiving a data message from at least one of the plurality of base station controllers on the active (IPSC);

detecting a communication failure by at least one of the active process and the standby process, in response to the received data message; and

automatically configuring the redundant (IPSC) to become the active (IPSC).

16. The non-transitory computer readable storage medium of claim 15, wherein the data message is destined for the at least one mobile switching center.

17. The non-transitory computer readable storage medium of claim 15, further comprising:

allocating a port on the active (IPSC) for the at least one base station controller that transmitted the data message and forwarding the data message from the active (IPSC) to the at least one mobile switching center.

18. The non-transitory computer readable storage medium of claim 15, further comprising:

determining that the failure occurred while being processed by the active process.

19. The non-transitory computer readable storage medium of claim 15, further comprising:

disconnecting all active calls being processed by the plurality of base station controllers as a result of the communication failure being detected.

20. The non-transitory computer readable storage medium of claim 15, wherein the communication failure is detected by the active (IPSC), and wherein the communication failure is determined to be a lack of communication with the at least one mobile switching center.
