First Claim
1. A core network apparatus configured to be connected to a plurality of base station apparatus each for forming a cell for connecting to a terminal through a wireless link, for being connected to a terminal through said base station apparatus, said core network apparatus comprising:
- a service area information storage for separately managing the information of an idle mode service area in which a terminal in an idle mode, in which the terminal is not communicating, being connected, and the information of an active mode service area in which a terminal in an active mode, in which the terminal is communicating, being connected, said active mode service area being wider than said idle mode service area, with respect to respective cells of said base station apparatus; and
a connection controller for keeping the core network apparatus connected to a terminal in the idle mode which is connected to the core network apparatus through a base station apparatus in said idle mode service area as long as said terminal in the idle mode is located in said idle mode service area, and keeping the core network apparatus connected to a terminal in the active mode which is connected to the core network apparatus through a base station apparatus in said active mode service area as long as said terminal in the active mode is located in said active mode service area.

Abstract
A mobile communication system for relaying user data includes a plurality of base station apparatus and a core network apparatus. Each of the base station apparatus forms a cell for connecting to a terminal through a wireless link. The core network apparatus can be connected to the base station apparatus. Even when the terminal moves between the base station apparatus while the terminal is in an active mode in which the terminal is communicating, the core network apparatus which is connected to the terminal keeps itself connected to the terminal.
