CLAIMS

1 . A method of operating a communications network interconnected with a plurality of other communications networks, the method comprising the steps of:
establishing
a location register wherein each entry comprises a user identifier and a respective network identifier representing the latest notification to said communications network of the location of a respective user-associated data package, and
storage for user-associated data packages currently located at said communications network;
responding to an originating call to a called user by
accessing the location register in accordance with the identity of that called user, retrieving the respective network identifier, and
performing connection set up on the basis that the destination network for the called user is that communications network which corresponds to that retrieved network identifier; and
responding to receipt from a said other communications network of a move request in respect of a specified user by
retrieving that specified user's associated data package from storage, and
sending the retrieved data package to said other communications network.

2. A method as claimed in claim 1 , including the steps of connecting calls for a particular user, whose user-associated data package is currently located at said communications network, to a message recording service and recording messages, and incorporating those recorded messages within that particular user's data package.

3. A method as claimed in either claim 1 or claim 2, including the step of responding to receipt from said other communications network of a message in respect of that specified user and containing location register update information by changing the respective network identifier to that for said other communications network.

4. A method as claimed in any one of claims 1 to 3, wherein a user's data package incorporates call handling information, and including the steps of:
responding to receipt of a message in respect of that specified user and containing call handling information by storing that call handling information, and associating that specified user's identity in the location register with that stored call handling information;
and wherein the step of responding to an originating call includes
retrieving the call handling information associated with the called user, and performing connection set up in accordance with the retrieved call handling information.

5. A method as claimed in any one of claims 1 to 4, including the steps of: responding to a request from a user, currently registered with said communications network as a visitor, for that visiting user's associated data package to be moved to said communications network by
accessing the location register in accordance with the identity of that visiting user, and
if there is a corresponding entry,
retrieving the respective network identifier, and
sending a move request in respect of that visiting user to the other communications network corresponding to the retrieved network identifier,
else
requesting of at least one of the other communications networks a network identifier for the other communications network currently storing that visiting user's associated data package, and upon receipt of the requested network identifier
sending a move request in respect of that visiting user to the other communications network corresponding to the received network identifier.

6. A method of operating a communications network interconnected with a plurality of other communications networks, at least one of said other communications networks operating in accordance with claim 1 , the method comprising the steps of: responding to a request from a user, currently registered with said communications network as a visitor, for that user's associated data package to be moved to said communications network by
requesting of at least one of the other communications networks a network identifier for the other communications network currently storing that visiting user's associated data package, and upon receipt of the requested network identifier
sending to the other communications network corresponding to the received network identifier a request for that user's associated data package to be moved to said communications network.

7. A method as claimed in either claim 5 or claim 6, wherein the requesting step comprises sending a query message in respect of that visiting user to that one of said other communications networks which corresponds to the global address of that visiting user.

8. A method as claimed in any one of claims 5 to 7, wherein the requesting step comprises sending a query message in respect of that visiting user to every one of said other communications networks.

9. A method as claimed in any one of claims 4 to 8, including the steps of retrieving instructions from a received user's data package, and in accordance with those instructions, effecting modification of each of a predetermined set of the communications networks.

10. A method as claimed in claim 9, wherein the step of effecting modification comprises generating a message and sending that message to each of said predetermined set of the communications networks other than that communications network which performs the step of retrieving instructions.

1 1 . A method as claimed in either claim 9 or claim 10, wherein those instructions comprise instructions for modifying the respective location registers by changing the respective stored network identifier to that of the network which performs the step of retrieving instructions.

1 2. A method as claimed in any one of claims 9 to 1 1 , wherein the instructions comprise instructions for storing call handling information and modifyi the respective location registers to associate the user identity entry there corresponding to the received data package, with that stored call handli information.

13. A communications network arranged for interworking with a plurality of oth communications networks and employing a global addressing scheme, the netwo comprising:
means for storing user-associated data packages, and entries each comprising a us identifier and a respective network identifier representing the latest notification said communications network of the location of a respective said user-associate data package;
means arranged to respond to an originating call to a called user by
accessing the storing means in accordance with the identity of that called user, retrieving the respective network identifier, and
performing connection set up on the basis that the destination network for the calle user is that communications network which corresponds to that retrieved networ identifier; and
means arranged to respond to receipt from a said other communications network of move request in respect of a specified user by
retrieving that specified user's associated data package from storage, and
sending the retrieved data package to said other communications network.

14. A network as claimed in claim 13, having a message recording system, anc including means arranged to respond to messages recorded by the message recordinc system in respect of a particular user whose data package is currently stored in saic storing means by incorporating those recorded messages within that particular user's data package.

15. A network as claimed in either claim 1 3 or claim 14, including means arranged to respond to receipt from said other communications network of a message in respect of that specified user and containing location update information by changing the respective network identifier to that for said other communications network.

1 6. A network as claimed in any one of claims 1 3 to 1 5, for use when a user's data package incorporates call handling information, and including means arranged to respond to receipt of a message in respect of that specified user and containing call handling information by storing that call handling information in the storing means in association with that specified user's identity; and wherein said means arranged to respond to an originating call further responds by retrieving the call handling information associated with the called user, and by performing connection set up in accordance with the retrieved call handling information.

1 7. A network as claimed in any one of claims 1 3 to 1 6, including means arranged to respond to a request from a visiting user for that visiting user's associated data package to be moved to said communications network, by

retrieving the respective network identifier, and
sending a move request in respect of that visiting user to the other communications network corresponding to the retrieved network identifier,
else
requesting of at least one of the other communications networks a network identifier for the other communications network currently storing that visiting user's associated data package, and upon receipt of the requested network identifier
