Abstract
A system for hiding an internal topology of a network having plurality of client and server entities is provided herein. The system comprises a topology hiding node that coordinates communication between systems in two distinct networks: Home Public Land Mobile and Visited Public Land Mobile. The topology hiding node includes long term storage and a short term storage which includes a change list.A real identity of one system entity is represented by at least one virtual identity allocated from a group of at least two virtual identities, when communicating with the other system entities, and the relation between the virtual identities and the real identities of a current communication session is recorded in the change list and stored in short term storage and the relation between the virtual identities and the real identities of a previous communication sessions is stored in the long term storage.
