Abstract: A method for constructing a zone database for providing home zone services to the subscribers of a mobile communications system, comprises the steps of dividing a service area into a plurality of home service zones; simulating the communication coverage of the base stations for each of the home service zones; detecting the pilot signal strengths of the base stations; and, selecting a given number of the base stations in the order of pilot signal strength as the home zone.

Abstract: A recording and reproducing apparatus using a video tape includes a user interfacer for generating comment information in response to a user key input, a video cassette recorder for recording the comment information on a predetermined region in a video tape, a transmission interfacer for enabling the user interfacer and the video cassette recorder to a transmit and receive a signal therebetween and a display for displaying a signal reproduced from the video cassette recorder so that user can recognize the signal. This apparatus is particularly useful for an educational-purposed video system.
