METHOD AND SYSTEM FOR DYNAMIC CALL ANCHORING
First Claim
1. A method of dynamic call anchoring to support call continuity for a subscriber who roams between an enterprise network and another network, comprising:
- on call setup between a device operated by the subscriber and a device operated by another party, storing call context information about the call so that the call context information is available to be retrieved via a data network by an authorized application that requires the call context information when criteria are satisfied for a handover of the call form the enterprise network to the other network or from the other network to the enterprise network;
when the criteria are satisfied, retrieving the call context information and formulating a call setup message to release the call from the one network and dynamically anchor the call in the other network without disconnecting the device operated by the other party, by using the call context information to invoke a replaces functionality in a switch in the enterprise network.

Abstract
Calls to/from one or more devices operated by a subscriber are dynamically anchored as a need is imposed by mobility of the subscriber. A dynamic call anchoring client application that operates on the one or more devices operated by the subscriber may determine when criteria are satisfied for handover of a call in progress form an enterprise network to another network, or vice versa. Replaces functionality in a switch in the enterprise network is used to effect the dynamic call anchoring by replacing a call leg anchored in one of the networks with a call leg anchored in the other of the networks.

11. A system for dynamically anchoring selected calls to support call continuity for a subscriber who roams between an enterprise network and another network, comprising:
-
an application client executed by communications devices operated by the subscriber, the application client being programmed to collect call context information respecting calls set up to/from the subscriber and to store the call context information in a data store; and a converged services node in a service provider network, comprising a dynamic call anchoring application programmed to;
retrieve the call context information from the data store;
to formulate a call setup message containing the call context information to invoke replaces functionality in a switch in the enterprise network when handover of a call to/from the subscriber is required; and
, to forward the call setup message to the switch in the enterprise network. - View Dependent Claims (12)

17. An application client for dynamically anchoring selected calls to support call continuity for a subscriber who roams between an enterprise network and another network, comprising:
-
program instructions for collecting call context information when a call is set up to/from the subscriber and program instructions for storing the call context information; and program instructions for launching a call setup message when criteria are satisfied for handover of a call from the enterprise network to the other network or handover of the call from the other network to the enterprise network.
