Abstract
A method and apparatus for transferring a user data profile from a user's home terminal to a visiting terminal is disclosed. User or network configuration settings are transferred from a home telephony adapter to a visiting telephony adapter. In accordance with one embodiment, a computer readable medium, such as a flash drive is inserted into the home telephony adapter and, either with or without authentication, user or network configuration settings are transferred from the home telephony adapter to the medium. In another embodiment, the medium is then inserted into the visiting telephony adapter.
Claims9
A system for roaming in a telephony data network, the system comprising:
- a home telephony adapter for automatically transferring, without providing first authentication information, user profile data associated with the home telephony adapter to a non-transitory computer readable medium, wherein the user profile data comprises a telephone number associated with the home telephony adapter, settings related to features that can be applied to a call including caller identification settings, call waiting settings, three-way calling settings, and call forwarding settings, and settings related to a telephone associated with the home telephony adapter including ring tone selection settings, display settings, and telephone book information;
- a visiting telephony adapter:
- for receiving second authentication information;
- for receiving, based on the second authentication information, the user profile data from the non-transitory computer readable medium;
- for transmitting a registration message to a call control element, the registration message comprising a request to associate the telephone number associated with the home telephony adapter with an internet protocol address associated with the visiting telephony adapter;
- and for receiving a forwarded telephone call wherein the forwarded telephone call was destined for the telephone number associated with the home telephony adapter, and the call control element:
- for authenticating the registration message;
- and for associating the telephone number associated with the home telephony adapter with the internet protocol address associated with the visiting telephony adapter.

A method comprising:
- automatically receiving, without first authentication information being provided, user profile data associated with a home telephony adapter, wherein the user profile data comprises a telephone number associated with the home telephony adapter, settings related to features that can be applied to a call including caller identification settings, call waiting settings, three-way calling settings, and call forwarding settings, and settings related to a telephone associated with the home telephony adapter including ring tone selection settings, display settings, and telephone book information;
- receiving second authentication information;
- transferring, based on the second authentication information, the user profile data to a visiting telephony adapter;
- transmitting a registration message from the visiting telephony adapter to a call control element, the registration message comprising a request to associate the telephone number associated with the home telephony adapter with an internet protocol address associated with the visiting telephony adapter;
- authenticating the registration message;
- associating the telephone number associated with the home telephony adapter with the internet protocol address associated with the visiting telephony adapter;
- and
- receiving a forwarded telephone call at the visiting telephony adapter, wherein the forwarded telephone call was destined for the telephone number associated with the home telephony adapter.

A method of storing user profile data in a non-transitory computer readable medium comprising:
- automatically receiving, without first authentication information being provided, from a home telephony adapter, user profile data associated with the home telephony adapter, wherein the user profile data comprises a telephone number associated with the home telephony adapter, settings related to features that can be applied to a call including caller identification settings, call waiting settings, three-way calling settings, and call forwarding settings, and settings related to a telephone associated with the home telephony adapter including ring tone selection settings, display settings, and telephone book information;
- storing the user profile data in the non-transitory computer readable medium;
- and transmitting the user profile data, after second authentication information is provided, to a visiting telephony adapter to facilitate association of the telephone number associated with the home telephony adapter with an internet protocol address associated with the visiting telephony adapter:
- wherein the visiting telephony adapter transmits a registration message to a call control element, wherein the registration message comprises a request to associate the telephone number associated with the home telephony adapter with an internet protocol address associated with the visiting telephony adapter and third authentication information, wherein the visiting telephony adapter registers with the a network registration database in a voice over internet protocol network and informs the voice over internet protocol network that settings included in the user profile data including the settings related to features that can be applied to a call and the settings related to a telephone associated with the home telephony adapter are maintained, and wherein the call control element authenticates the registration message based on the third authentication information and associates the telephone number associated with the home telephony adapter with the internet protocol address associated with the visiting telephony adapter.
