<p>While the LTE has been in widespread use and the line speed for data communications has also been improved, the exploding data traffic required by evolving applications is thought to increase the utilization factor of public WiFi services from now on. The throughput (TP) and the round trip time (RTT), however, might become longer for reasons of increasing heavy processing load on a public WiFi station or network load. On the other hand, the required TP or RTT are totally dependent on the application which a user is working on. This paper defines a degree of satisfaction of terminal that is the difference between the required TP or RTT for a user's application and the actual TP or RTT obtained when a mobile terminal gets connected to a station. The paper firstly formulates a problem to assign some mobile terminals with the different communications services by means of graph theory, and it also proposes a method to maximize the degree of satisfaction of terminal in the whole system with considering the required TP or RTT for user's applications based on a connection service determination logic by Hungarian method.</p>
