Due to rapid growth of wireless communication technology, people frequently view maps or get related services from the handheld devices, such as mobile phones and PDAs. Range queries, as one of the most commonly used tools, a spatial database. However, due to the limits of are often posed by the users to retrieve needful information from communication bandwidth and hardware power of handheld devices, displaying all the results of a range query on a handheld device is neither communication efficient nor informative to the users. This is simply because that there are often too many results returned from a range query. In view of this problem, we present a novel idea of effective navigation and Best edge cut mechanisms for queried results, that increases the performance and reduces the communication cost and also effects the navigation cost ,also offers better usability to the users, providing an opportunity for interactive exploration. The usefulness of the concise range queries is confirmed by comparing it with other possible alternatives, such as sampling and clustering and edge cut mechanisms.
