METHOD AND AN APPARATUS FOR PERFORMING HANDOVER USING A MOBILE COMMUNICATION SYSTEM IN A DIGITAL BROADCASTING SYSTEM, ESPECIALLY FOR SOLVING A PROBLEM THAT AN HANDOVER ERROR MAY BE GENERATED IN A TERMINAL IF THE TERMINAL DETERMINES WHETHER TO START A HANDOVER PROCESS BY USING ONLY STRENGTH OF A RECEIVED SIGNAL |
摘要 |
<p>A method is provided for performing handover by a terminal in a digital broadcasting system. The method includes measuring strength of a received signal from a serving broadcast transmitter while receiving a broadcast service, and comparing the measured strength of the received signal with a predetermined reference value; periodically measuring strength of the received signal while continuously receiving the broadcast service when the measured strength of the received signal is greater than the reference value; sending a handover start request message for the broadcasting system to a base station of a mobile communication system when the measured strength of the received signal is less than or equal to the reference value; and performing handover from the serving broadcast transmitter to a target broadcast transmitter upon receipt of an accept message for the handover start request for the broadcasting system from the base station.</p> |
