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.
