Topology Hiding Of Mobile Agents
First Claim
1. A communication infrastructure node for a mobile communication network, arranged to communicate with at least one mobile node using a first communication protocol and at least one host server, the infrastructure node further arranged to communicate with the mobile node with a second communication protocol in a packet based mobility enabled network, the infrastructure node comprising:
- a processor arranged with functionality for acting as a Care-of-Address identifying device for connecting a host address in the second communication protocol to a network identifier excluding network topology address information in the second communication protocol network and the processor further comprising means to use session management signaling of the first communication protocol as bearer of Internet Protocol (IP) based mobility control information of the second communication protocol.

Abstract
A method, infrastructure node (11, 12, 202), and mobile node (1) arranged to hide topology information from the user and mobile node by translating topology information to non-topology related address information and using session management messages of a first communication protocol as bearer for Internet Protocol mobility messages relating to a second communication protocol.

11. A method for hiding topology information in a mobile communication network comprising a first and second communication protocols, said method comprising the steps of:
-
translating in a node of said network a host Internet Protocol (IP) Address in the second communication protocol into a second address excluding network topology address information; and using one or several session management messages for the first communication protocol in the mobile communication network for distributing mobility IP control information of the second communication protocol between said node and a mobile node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

- 20. A mobile node for use in a mobile communication network, wherein said mobile node comprises processing means for connecting to an infrastructure node in said communication network with specific session management control messages for a first communication protocol for said mobile communication network and adding mobile Internet Protocol, i.e. IP, control messages for a second communication protocol to said session management messages, wherein control messages of the second communication protocol comprise a host server identifier excluding network topology address information.
