Call distribution method in a mobile switching system
First Claim
1. A method for distributing a call in a mobile switching network, comprising the steps of:
- transmitting a location registration request message from a mobile switching center to a corresponding one of a plurality of managed intelligence nodes upon receipt of a location registration request from a subscriber, the mobile switching center performing a signaling interfacing and switching function, the plurality of managed intelligence nodes including a visitor location register as a call server for performing a unified call control function;
reading in the corresponding managed intelligence node a mobile identification of the subscriber making a call and searching the mobile identification for a target managed intelligence node address upon receipt of the location registration request message, the target managed intelligence node corresponding to a target subscriber being called by the subscriber; and
determining whether a target prefix is a converted prefix having a prefix head digit of the target managed intelligence node when the target managed intelligence node address is searched, and immediately performing a location registration process when the target prefix is the converted prefix.

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.
