1. A method for providing softswitch failure protection in a communication network having a first softswitch and at least a second softswitch, the first and second softswitches selectably operable to perform control services at least at a selected part of the communication network, said method comprising:
- assigning an alias point code to the first softswitch;
assigning the alias point code to the second softswitch; and
generating a message comprising a destination point code that identifies a destination for the message, the destination point code comprising the alias point code.

Abstract
A method for providing softswitch failure protection in a communication network is provided that includes assigning an alias point code to a first softswitch. The alias point code is also assigned to a second softswitch. A message is generated that comprises a destination point code that is operable to identify a destination for the message. The destination point code comprises the alias point code.

6. A method for providing softswitch failure protection in a communication network having a first softswitch and a second softswitch, the first softswitch and the second softswitch selectably operable to provide control service at least at a selected portion of the communication network, said method comprising:
-
assigning a first alias point code to a first softswitch; assigning the first alias point code to a second softswitch; assigning a second alias point code to the first softswitch; assigning the second alias point code to the second softswitch; generating a first message at a first network element, the first message comprising a destination point code operable to identify a destination for the first message, the destination point code comprising the first alias point code. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A system for providing softswitch failure protection in a communication network, said system comprising:
-
a first network element operable to generate a first message comprising a destination point code that is operable to identify a destination for the first message, the destination point code comprising a first alias point code; a plurality of signal transfer points coupled to the first network element, a first softswitch coupled to the signal transfer points, the first softswitch operable to be identified by the first alias point code; and a second softswitch coupled to the signal transfer points, the second softswitch operable to be identified by the first alias point code. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for providing softswitch failure protection in a communication network, said method comprising:
-
sending a transfer allowed message comprising a first alias point code from a first softswitch to each of a plurality of adjacent signaling transfer points; sending a transfer prohibited message comprising the first alias point code from a second softswitch to each of the adjacent signaling transfer points; monitoring the first softswitch for failure; and if the first softswitch fails, sending a transfer prohibited message comprising the first alias point code from the first softswitch to each of the adjacent signaling transfer points, establishing control with the second softswitch, and sending a transfer allowed message comprising the first alias point code from the second softswitch to each of the adjacent signaling transfer points. - View Dependent Claims (20)
