First Claim
Patent Images
1. A network server, comprising:
- a verification unit to determine if a mobile communication terminal entering a coverage area of a small-sized base station is a temporary closed subscriber group (CSG) member, and to verify an expiration time offered to the mobile communication terminal if the mobile communication terminal is the temporary CSG member;
a determination unit to compare the expiration time to a first threshold time value; and
a message transmission unit to transmit to the mobile communication terminal a driving command message including the expiration time if the expiration time is less than the first threshold time value to drive a terminal timer of the mobile communication terminal to reduce the expiration time

Abstract
A mobile communication terminal may include a reception unit to receive a message from a network server in accordance with an entrance of the mobile communication terminal to coverage area of a small-sized base station, a message definition unit to verify that an expiration time is included in the received message defining the message as a driving command message, and a terminal control unit to extract the expiration time from the defined driving command message and to drive a terminal timer to reduce the extracted expiration time.
