An approach for establishing a communication session according to a subscriber profile that is automatically updated is disclosed. A locator device, which is associated with a subscriber and includes a Global Positioning System (GPS) transponder, outputs geographic information that is transmitted to a communications network for establishing the communication session. The geographic information corresponds to one of a plurality of addresses specified in the subscriber profile to set a current address. The addresses are associated with a plurality of devices adapted to complete the communication session. The one address is designated as the current address if the geographic information corresponds to the one address, otherwise the current address is set to a default address, wherein the communication session is established based on the current address.
