The method for sending out seeking message includes steps: constructing multiple seeking messages to same user terminal; sending out multiple seeking messages within a seeking cycle. The method for receiving seeking message includes steps: receiving the seeking message; and receiving seeking messages for many times within a seeking cycle based on judgment rules. The seeking message includes steps: constructing multiple seeking messages to same user terminal; sending out multiple seeking messages within a seeking cycle; and receiving seeking messages for many times within a seeking cycle based on judgment rules. Since sending out seeking messages for many times within a seeking cycle, and receiving seeking messages for many times within a seeking cycle, the invention raises probability for receiving correct seeking message within a seeking cycle.
