Abstract: In the case where a plurality of wireless systems differing in service area from each other are present, there is provided a wireless terminal having a function for collecting a history of application information, and a history of position information, a function for transmitting these histories to a priority table control server, a function whereby the priority table control server prepares a priority table on the basis of information obtained, and a function whereby the information is transmitted to the wireless terminal. The wireless terminal selects a connection destination on the basis of the information.

Abstract: When a TCP packet communication acceleration technique is applied to a wireless communication network, an acceleration effect is determined according to various pieces of information in real time, and acceleration control is dynamically performed to efficiently accelerate the communication by the use of the TCP of a wireless terminal present in the wireless communication network. A wireless communication system including at least one wireless terminal and at least one base station that communicates with the wireless terminal further includes an information collection server that collects various pieces of information from the base station and the wireless terminal. The base station includes a packet acceleration unit that accelerates a TCP packet communication, and the information collection server determines whether to accelerate the base station from the various pieces of information, or not, and controls the acceleration of the base station on the basis of its determination result.
