A mobile communication system for providing a home zone service and a method thereof. In the mobile communication system, a home zone signal generator generates a home zone signal, a mobile radio terminal receives the home zone signal and determines whether the mobile radio terminal is currently within or outside a home zone based on the strength of the home zone signal, and a base station communicates with the mobile radio terminal. A visitor location register temporarily stores a first and a second telephone numbers of a subscriber, wherein each telephone number represents different charge rates. A mobile exchange receives a call information, a mobile identification number, and the home zone in/out information from the base station and selects one of the first and second telephone numbers of a subscriber corresponding to the mobile identification number and the home zone in/out information. A billing center receives the call information and one of the selected first and the second telephone numbers from the mobile exchange and generates a service charge for the call connection. |

DETAILED DESCRIPTION It is, therefore, an object of the present invention to provide a mobile communication system and method for providing home zone service in a wireless communication network, wherein a wireless subscriber using a single terminal is charged for the call inside a home zone at a first charge rate and the call outside the home zone at a second charge rate.
The above object is achieved by providing a mobile communication system, which includes a home zone signal generator for generating a home zone signal; a mobile radio terminal for receiving the home zone signal and for determining whether the mobile radio terminal is currently within the home zone based on the strength of the home zone signal; and, a base station for communicating with the mobile radio terminal.
Accordingly, a visitor location register temporarily stores the first and the second telephone numbers of a subscriber, for which different charge rates are applied.
A mobile exchange receives the call information, a mobile identification number, and the home zone in/out information from the base station and selects the first or the second telephone number of the subscriber that corresponds to the mobile identification number by referring to the visitor location register according to the home zone in/out information.
A billing center receives the call information and the first and the second telephone numbers from the mobile exchange and provides billing for the call corresponding to the selected telephone number.
