A METHOD FOR ENSURING THE INFORMATION CONSISTENCY BETWEEN THE NETWORK NODES

摘要

A method for ensuring the information consistency between the network nodes comprises that save the route information of the user acquired by Serving Call Session Control Function (S-CSCF) entity after S-CSCF entity acquires the user's route information; S-CSCF entity acquires the user route information and the user profile information while S-CSCF entity restarts after a failure; S-CSCF informs the service control platform to implement the service control procedure corresponding to the de-registration of the user according to the acquired user profile information and informs the user to implement the de-registration procedure according to the acquired route information. The present invention ensures the information consistency between every network nodes so that the reliability and the security of the IMS network is improved greatly.
