Abstract:

Methods and apparatus for providing a mediation device infrastructure that allows a mobile node to be tapped while roaming among and within service providers are disclosed. In one embodiment, a method includes determining when a node that is tapped by a first mediation device has moved from a first domain associated with the first mediation device into a second domain associated with a second mediation device. A first packet is sent to the second mediation device if the node has moved. The first packet provides an indication that the second mediation device is to tap the node. The method also includes opening a call data channel to the second mediation device, and receiving information from the second mediation device on the call data channel that is obtained by the second mediation device from the node. Finally, the method includes providing the information to the first mediation device.

Abstract:

In an embodiment, a care-of address associated with a first node coupled to a communications network via an access node is received. The care-of address may be contained in a notification message sent by a home agent associated with the first node or by a binding update message sent by the first agent. The access node is identified using the care-of address. A request to tap communications associated with the first node at the access node is generated and the request is forwarded to the access node to cause communications associated with the first node to be tapped at the access node.
