Abstract
A method for achieving operational reliability in an overlayed network of service nodes is disclosed. The overlayed network of service nodes is connected to a public telecommunications network. In response to a party using a subscriber number to make a call, the public telecommunications network routes the call to a preferred service node. The preferred service node is capable of providing a plurality of services in response to such a call. If the preferred service node experiences a failure or is otherwise not operational, and does not respond to such a call, the public telecommunications network reroutes the call to a standby service node, which provides the same services as the preferred service node.
Claims37
A method for achieving operational reliability in a service network, comprising the steps of:
- in response to a party using a subscriber number to make a call, a public telecommunications network routing said call to a preferred service resource, said preferred service resource providing at least one service in response to said call, and said preferred service resource comprising part of said service network;
- and
- if said preferred service resource does not respond to said call, said public telecommunications network rerouting said call to a standby service resource, said standby service resource providing said at least one service in response to said call, and said standby service resource comprising part of said service network.
An overlayed service network in conjunction with a second network, comprising:
- a maintenance server, said maintenance server comprising part of said overlayed service network;
- a plurality of service resources coupled to said maintenance server, said plurality of service resources comprising part of said overlayed service network;
- and
- a switch, responsive to a directive from said maintenance server, for routing a call to a first of said plurality of service resources, said switch comprising part of said second network, said first of said plurality of service resources providing at least one service in response to said call, and routing said call to a second of said plurality of service resources if said first of said plurality of service resources is unresponsive to said call, said second of said plurality of service resources providing said at least one service in response to said call.

An overlayed service network in conjunction with a second network, comprising:
- a maintenance server, said maintenance server comprising part of said overlayed service network;
- a plurality of service resources coupled to said maintenance server, said plurality of service resources comprising part of said overlayed service network;
- and
- a switch, responsive to a directive from said maintenance server, for routing a call to a preferred service resource of said plurality of service resources, said switch comprising part of said second network, said preferred service resource of said plurality of service resources providing at least one service in response to said call, and routing said call to a standby service resource of said plurality of service resources if said preferred service resource of said plurality of service resources is unresponsive to said call, said standby service resource of said plurality of service resources providing said at least one service in response to said call.
1 more element
An overlayed service network in conjunction with a second network, comprising:
- a maintenance server, said maintenance server comprising part of said overlayed service network;
- a plurality of service resources coupled to said maintenance server, said plurality of service resources comprising part of said overlayed service network, at least a first of said plurality of service resources being designated as a preferred service resource with respect to a first subscriber based, at least in part, on a first subscriber number and at least a second of said plurality of service resources being designated as a standby service resource with respect to said first subscriber;
- and
- a switch, responsive to a directive from said maintenance server, for routing a call to said preferred service resource of said plurality of service resources, said switch comprising part of said second network, said preferred service resource of said plurality of service resources providing at least one service in response to said call, and routing said call to said standby service resource of said plurality of service resources if said preferred service resource of said plurality of service resources is unresponsive to said call, said standby service resource of said plurality of service resources providing said at least one service in response to said call.
1 more element
A method for achieving reliability for an overlayed network of resources associated with a telecommunications network, comprising the steps of:
- routing, by said telecommunications network, a call to a first resource of said overlayed network of resources based, at least in part, on a first number that is associated with said first resource;
- re-routing, by said telecommunications network, said call to a second resource of said overlayed network of resources when said first resource is non-responsive to said call;
- and
- notifying, by said second resource, a maintenance resource of said overlayed network of resources of the nonresponsiveness of said first resource based, at least in part, on said first number.
1 more element
A network of resource nodes having reliability procedures that operate in conjunction with an associated telecommunications network, comprising:
- a first resource node, said first resource node corresponding to a first and a second plurality of numbers such that a call associated with a first number of said first plurality of numbers is directed to said first resource node by said telecommunications network;
- a plurality of second resource nodes, at least a second resource node of said plurality of second resource nodes having access to at least a portion of said second plurality of numbers, said at least a second resource node capable of receiving said call as re-directed by said telecommunications network when said first resource node is unresponsive to said call and determining that a second number associated with the re-directed call is part of said second plurality of numbers;
- a maintenance resource node in communication with said first resource node, said at least a second resource node, and said telecommunications network;
- and
- wherein said at least a second resource node is further capable of communicating to said maintenance resource node that said first resource node is unresponsive when said at least a second resource node determines that said second number associated with the re-directed call is part of said second plurality of numbers.
2 more elements
A method for sharing maintenance actions between two networks, comprising the steps of:
- providing a telecommunications network and an overlayed network of resources, said overlayed network of resources comprising a plurality of service nodes that operate independently of said telecommunications network;
- directing, by said telecommunications network, a call to a first service node of said plurality of service nodes based, at least in part, on a number;
- detecting, by said telecommunications network, a lack of response from said first service node with respect to said call;
- re-directing, by said telecommunications network responsive to the detected lack of response from said first service node, said call to a second service node of said plurality of service nodes based, at least in part, on said number;
- and
- determining, by said overlayed network of resources, that said number is one of a plurality of numbers for which said first service node is a primary service node and said second service node is a standby service node.
3 more elements
A network of resource nodes having reliability procedures that operate in conjunction with an associated telecommunications network, comprising:
- a first resource node, said first resource node corresponding to a first plurality of numbers such that a call associated with a first number of said first plurality of numbers is directed to said first resource node by said telecommunications network;
- a plurality of second resource nodes, at least a second resource node of said plurality of second resource nodes corresponding to a second plurality of numbers and having access to at least a portion of said first plurality of numbers, said at least a second resource node capable of receiving said call as re-directed by said telecommunications network when said first resource node is unresponsive to said call and determining that said first number associated with the re-directed call is part of said at least a portion of said first plurality of numbers;
- a maintenance resource node in communication with said first resource node, said at least a second resource node, and said telecommunications network;
- and
- wherein said at least a second resource node is further capable of communicating to said maintenance resource node that said first resource node is unresponsive when said at least a second resource node determines that said first number associated with the re-directed call is part of said at least a portion of said first plurality of numbers.
