Patent ID: 8165137

Claim:
A method for migrating a subscriber from an originating system to a terminating system, comprising the steps of: establishing a socket connection directly between intelligent processor unit nodes of the originating system and intelligent processor unit nodes of the terminating system; transferring home location register static data and home location register transient data for the subscriber via the socket connection, wherein the home location register static data and home location register transient data are transferred in parallel between the intelligent processor unit nodes of the originating system and the intelligent processor unit nodes of the terminating system, and bypassing the platform manager nodes of the originating system and the platform manager nodes of the terminating system during the parallel transferring of the home location register static data and the home location register transient data, the transferring comprising: filling a move buffer with home location register static data, indicating a filled move buffer, inserting the indicated filled move buffer in the intelligent processor unit nodes of the terminating system, packing a synchronization buffer with home location register transient data, receiving the home location register transient data from the packed synchronization buffer by the terminating system; and synchronizing the home location register transient data between the intelligent processor unit nodes of the originating system and the intelligent processor unit nodes of the terminating system.
