Methods, systems, and computer program products for selectively limiting access to signaling network nodes that share a point code
First Claim
1. A method for selectively limiting access to signaling nodes that share a point code, the method comprising:
- provisioning at least a first destination node and a second destination node in a communications network to be identified by a common point code;
routing messages to the first and second destination nodes respectively using first and second exception routes that are keyed by different combinations of parameters that include the common point code as a destination point code (DPC);
providing at least one default route to the first and second destination nodes;
detecting failure of at least one of the first exception route and the first destination node; and
in response to detecting the failure, restricting fallback access to the second destination node via the at least one default route.

Abstract
Methods, systems, and computer program products for selectively limiting access to signaling network nodes that share a point code are disclosed. According to one method, first and second destination nodes are provisioned to be identified by a common point code. Messages are routed to the first and second destination nodes respectively using first and second exception routes that are keyed by different combinations of parameters that include the common point code as a destination point code (DPC). At least one default route is provided to the first and second destination nodes. Failure of at least one of the first exception route and the first destination node is detected. In response to detecting the failure, fallback access to the second destination node via the at least one default route is restricted.

12. A system for selectively limiting access to signaling nodes in a communications network, the system comprising:
-
first and second destination nodes identified by a common point code; and
a routing node for routing messages to the first and second destination nodes using first and second exception routes that are keyed by different combinations of parameters that include the common point code as a destination point code (DPC), for providing at least one default route to the first and second destination nodes, for detecting failure of at least one of the first exception route and the first destination node, and, in response to detecting the failure, for restricting fallback access to the second destination node via the at least one default route. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
