A method for providing a location based service (LBS) in a point-to-multipoint broadcasting system comprises, in a mobile station, receiving a transmitter identifier (ID) from a point-to-multipoint transmitter, and obtaining location information based on the transmitter ID. The method also comprises determining a service area for the LBS based on obtained location information, in the mobile station. The method may further comprise updating stored location information in the mobile station based on the obtained location information. The method may further comprise receiving an LBS selection from a user, and transmitting the LBS selection to the point-to-multipoint transmitter. The method may further comprise receiving the LBS from the point-to-multipoint transmitter based on transmitted LBS selection. The point-to-multipoint broadcasting system may comprise a digital multimedia broadcast (DMB) system. The DMB system may comprise at least one of a satellite DMB system and a terrestrial DMB system. |
