PROBLEM TO BE SOLVED: To make a sub communication device without a call control function have an interface with an external apparatus and to make the sub communication device make a call on the basis of a connection instruction from the external apparatus.SOLUTION: A communication terminal 1 according to the present invention comprises: a main communication device 10 corresponding to a first communication system; and a sub communication device 20 that corresponds to a second communication system having communication speed faster than the first communication system, performs communication processing according to an instruction from the main communication device 10, and has an interface with an external apparatus. The sub communication device 20 transfers a connection instruction from the external apparatus 50 to the main communication device 10. The main communication device 10 instructs the sub communication device 20 to make a call on the basis of the connection instruction.SELECTED DRAWING: Figure 1 |
