Apparatus and method for controlling broadcast channel using position information of mobile communication terminal
First Claim
1. An apparatus for maintaining a broadcast channel transmitted at a first frequency when the apparatus moves to an area where the broadcast channel is transmitted at a different frequency, comprising:
- a mobile terminal for periodically receiving position information from a base station, and transmitting the position information to a broadcast channel controller; and
a broadcast unit for receiving the first broadcast frequency selected by a user, and transmitting the first broadcast frequency to the broadcast channel controller, wherein the broadcast channel controller is connectable to the mobile terminal and the broadcast unit, associates the broadcast channel with different broadcast frequencies for different areas, stores the broadcast channel associated with different broadcast frequencies for the different areas, stores the position information received from the mobile terminal and the broadcast frequency received from the broadcast unit, compares previous position information with current position information at each reception time of the position information, determines whether the apparatus moves from a first area to a second area using the result of the comparison, and provides the broadcast unit with a new broadcast frequency for providing the broadcast channel in the second area at the new broadcast frequency.

Abstract
An apparatus and method for controlling a broadcast channel using position information of a mobile terminal. The broadcast channel control apparatus maintains a radio or TV broadcast channel currently broadcast to a user who is in motion when the same broadcast channel as the radio or TV broadcast channel is broadcast to a plurality of areas at different broadcast frequencies. The method for maintaining the same broadcast channel using a broadcast channel controller even though the user moves from a first area to a second area includes the steps of a) associating different broadcast frequencies for different areas with a selected broadcast channel, and storing the associated broadcast frequencies, b) receiving position information from the mobile terminal and receiving a broadcast frequency from the broadcast unit, and storing the received position information and the received broadcast frequency and c) comparing previous position information with current position information, determining whether the user moves from a first area to a second area, and providing the broadcast unit with a new broadcast frequency for providing the user with the broadcast channel even in the second area at the new broadcast frequency.

11. A method for maintaining a broadcast channel received at a first frequency when a broadcast receiver moves to an area where the broadcast channel is transmitted at a different frequency, comprising the steps of:
-
a) associating different broadcast frequencies for different areas with the broadcast channel, and storing the associated broadcast frequencies;
b) periodically receiving position information from the mobile terminal and receiving a broadcast frequency from the broadcast unit, and storing the received position information and the received broadcast frequency; and
c) comparing previous position information with current position information each time the position information received, determining whether the broadcast receiver moves from a first area to a second area, and determining a new broadcast frequency for providing the broadcast channel at the new broadcast frequency. - View Dependent Claims (12, 13, 14)

15. A method for controlling a mobile terminal which includes a radio module to perform a radio function, and periodically receives position information from a base station, comprising the steps of:
-
a) associating different broadcast frequencies for different areas with the same broadcast channel, storing the associated broadcast frequencies, and storing the received position information and a broadcast frequency selected by a user; and
b) comparing previous position information with current position information, determining whether the mobile terminal moves from a first area to a second area, providing the radio module with a new broadcast frequency for providing broadcast channel at the new broadcast frequency in the second area at the new broadcast frequency. - View Dependent Claims (16, 17)
