ABSTRACT:
A mobile switching system distributes location registration and mobile subscriber's outgoing call using a plurality of managed intelligence nodes (MINs) having a call server function. Upon receipt of a location registration or outgoing call request from a subscriber, a Mobile Switching Center (MSC) transmits a location registration or outgoing call request message to a corresponding one of the managed intelligence nodes. Upon receipt of the location registration or outgoing call request message, the corresponding managed intelligence node reads a mobile identification of a calling party and searches the mobile identification for a target managed intelligence node address. When the target managed intelligence node address is searched, the managed intelligence node determines whether a target prefix is a converted prefix having a target managed intelligence node prefix head digit, and immediately performs a location registration or outgoing call process, when the target prefix is the converted prefix.
