A method and apparatus in accordance with the present invention includes a home agent and a mobile terminal that communicate to facilitate the home agent becoming aware of a device type and access technology being used to gain access to a network by way of the home agent so that the home agent may provide appropriate billing and network control. More specifically, the mobile IP registration process according to a mobile IP protocol is modified to add parameter extensions that allow the mobile terminal to provide this information. The two specific parameters that are added include one that defines the access technology and another that defines the device type in the described embodiments of the present invention. Specifically, the extension that defines the access technology includes a mobile IP client that has operator definable configurations that relate to the access technology. The mobile IP client specifies whether a wireless local area network or wireless cellular network is being used and, in one embodiment of the invention, which type of wireless local area network or cellular network is being used.
