METHOD AND SYSTEM FOR PRIVATE NETWORK SERVICE

摘要

The present invention relates to a method and a system for providing a private network service which is broken away from dependency of a terminal and provides a private network service. The private network service system according to the present invention comprises: a service connecting server which confirms identification information of the mobile terminal and requests a home subscriber server to change an access point name-operator identifier (APN-OI) when the service connecting server receives a connection request for a private network connection from a mobile communication terminal connected to a public network or receives a connection request for a private network connection of the mobile communication terminal from a third server; a home subscriber server which certificates whether the mobile terminal is subscribed in a private network service when there is a request for the APN-OI change from the service connecting server, and confirms an access point name (APN) contained in a subscriber profile of the mobile terminal and changes a public APN-OI recorded in the APN into a private APN-OI when the certification is successful; and a mobility management entity which receives a subscriber profile of the mobile terminal from the home subscriber server when the mobile terminal tried to connect, uses an IP address of a public gateway or a private gateway corresponding to the APN contained in the subscriber profile, and induces the mobile terminal to connect the public or private gateway.
