COMMUNICATION TERMINAL AND COMMUNICATION NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a communication terminal capable of dynamically reconfiguring connection with a different wireless communication network, and to provide a technique capable of efficiently using a number of wireless communication networks while reducing the size of a device operated by a user and performing power saving. SOLUTION: The communication terminal 20 capable of dynamically reconfiguring a connection method or the like with a plurality of wireless communication networks includes: a data communication aggregation device 21; a communication application execution device 22; and a local communication path 23 for connecting the data communication aggregation device with the communication application execution device. The data communication aggregation device 21 includes a single or a plurality of communication means corresponding to the plurality of wireless communication networks physically or logically configured and a first local communication means for communicating with the communication application execution device through the local communication path. The communication application execution device 22 includes a second local communication means for communicating with the data communication aggregation device through the local communication path and an application execution means for executing an application for communicating with at least an external communication network.
