Abstract
A method for use in a communications network in which a Mobile Node accesses the communications network via a proxy node. An access control node receives attachment information from the proxy node. The attachment information relates to an attachment to the communications network of the Mobile Node and includes an identifier of the Mobile Node. On the basis of the received information, a Binding Unique Identifier is determined to associate with a Care-of-Address used by the proxy node on behalf of the Mobile Node. The Binding Unique Identifier is sent to the proxy node for subsequent registration with a mobility anchor function.

A method for use in a communications network in which a Mobile Node accesses the communications network via a proxy node, the method comprising:
- receiving, at an access control node, attachment information from the proxy node, the attachment information relating to an attachment to the communications network of the Mobile Node and comprising an identifier of the Mobile Node;
- on the basis of the received information, determining a Binding Unique Identifier to associate with a Care-of-Address used by the proxy node on behalf of the Mobile Node;
- and
- sending the Binding Unique Identifier to the proxy node for subsequent registration with a mobility anchor function.
An access control node for use in a communications network in which a Mobile Node accesses the communications network via a proxy node, the access control node characterized by:
- means for receiving attachment information from the proxy node, the attachment information relating to an attachment to the communications network of the Mobile Node and comprising an identifier identifying the Mobile Node;
- means for determining, on the basis of the received information, a Binding Unique Identifier to associate with a Care-of-Address used for the Mobile Node;
- and
- a transmitter for sending the Binding Unique Identifier to the proxy node for subsequent registration with a mobility anchor function.
A proxy node for use in a communications network in which a Mobile Node accesses the communications network via the proxy node, the proxy node comprising:
- a receiver for receiving from the Mobile Node a message requesting attachment of the Mobile Node to the network via the proxy node;
- a transmitter for sending attachment information to an access control node, the attachment information comprising an identifier identifying the Mobile Node;
- means for receiving from the access control node a Binding Unique Identifier associated with a Care-of-Address used for the Mobile Node;
- and
- means for sending the Binding Unique Identifier, the Care-of-Address, and the association between the Binding Unique Identifier and the Care-of-Address to a mobility anchor function.
A Local Mobility Anchor for use a communications network in which a Mobile Node accesses the communications network via a proxy node, the Local Mobility Anchor comprises:
- a receiver for receiving from the proxy node a Care-of-Address associated with the Mobile Node, a Binding Unique Identifier relating to the Mobile Node and an association between the Binding Unique Identifier and the Care-of-Address.
