Using Registration State to Determine Potential Change in User Location

摘要

A method for determining potential relocation of an IP-enabled telephony device involves subscribing to a registration events package of a VoIP network, receiving one or more notifications indicating a registration state of the IP-enabled telephony device, and determining that the IP-enabled telephony device has potentially relocated, based on the registration state changes. A system for determining potential relocation of a user of a VoIP-enabled device includes an application server that includes a user relocation determination application that subscribes to a VoIP registration events package and determines whether the user has potentially relocated based on a change in registration state of the user's VoIP-enabled device.
