PROBLEM TO BE SOLVED: To provide a system and a method for synchronizing mobility management (MM) data between a CS domain and a PS domain.SOLUTION: A visitor location database 114 of a CS domain stores MM data regarding a mobile device 150. When the visitor location database 114 is to update the MM data regarding the mobile device 150 in such a manner that association with an MM node 122 about mobility management is added, the visitor location database 114 determines whether preceding association is present for another MM node 132. If so, the visitor location database cancels the preceding association with the other MM node and transmits a release indicator showing that the association has been canceled to the other MM node.SELECTED DRAWING: Figure 1 |
