COMMUNICATION SYSTEM, RADIO TERMINAL, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM

摘要

A radio terminal 100 capable of using a plurality of RATs includes a communication identification means 11 for identifying a type of communication made by the radio terminal 100, a connection control means 12 for controlling to use a communication route connected to which RAT as a communication route based on the communication type, and a route change means 13 for flowing communication through a designated RAT in response to an instruction of the connection control means 12. When a new communication route is connected to a RAT, the connection control means 12 instructs the route change means 13 to make user's data communication through an already-established RAT, and to flow communication required for NW connection establishment and quality measurement of a newly-connected communication route through a new RAT.

1. A radio terminal capable of using a plurality of RATs, comprising:
a communication identification unit which identifies unit which identifies a type of communication made by the radio terminal; a connection control unit which controls to use a communication route connected to which RAT as a communication route based on the type of the communication; and a route change unit which flows communication through a designated RAT in response to an instruction of the connection control unit, wherein when a new communication route is connected to a RAT, the connection control unit, instructs the route change unit, to make user's data communication by use of an already-established RAT and to flow communication required for NW connection establishment and quality measurement of a newly-connected communication route through a new RAT.
