Abstract

A method of use of a UMTS telecommunications network, comprising utilizing UMTS signalling to indicate changes in an IP sub-network. To register a Mobile Terminal (MT) or to update its location within the network, signalling relevant to the IP domain is transmitted with UMTS signalling in an integrated approach. This reduces the number of signalling messages that are required and minimizes delays.

Claims

1. A method for a mobile terminal in a UMTS and IP mobile telecommunications network to register its position by using UMTS ‘

register request’

messages, and/or UMTS ‘

register complete’

messages, to transmit IP information for IP registration.

2. A method as claimed in claim 1, wherein fields of information relevant to the IP domain are sent with the ‘

register request’

message.

3. A method as claimed in claim 2, wherein the fields are:

(1) type of home address, (2) type of care of address (COA), and, optionally, any of the following;

(3) home IP address, (4) home agents (HA) address and (5) last used COA.

4. A method as claimed in claim 3, wherein additional fields of information are sent with the ‘

register complete’

message.

5. A method as claimed in claim 4, wherein the additional fields comprise (1) home address, (2) COA type and (3) COA.

6. A method for a mobile terminal in a UMTS and IP mobile telecommunications network to update its location by using UMTS ‘

location update’

messages, and/or UMTS ‘

location update complete’

messages, to transmit IP information for IP location update.

7. A method as claimed in claim 6, wherein additional fields of information relevant to the IP domain are sent with the ‘

location update’

message.

8. A method as claimed in claim 7, wherein the additional fields comprise (1) home address, (2) COA type and (3) COA.

9. A method as claimed in claim 6, wherein additional fields are sent with the ‘

location update complete’

message.

10. A method as claimed in claim 9, wherein the additional fields comprise (1) type and (2) COA.
