To provide a communication device, a communication system, a control method for the communication device, and a program that change a communication path while keeping communication connection between communication devices.SOLUTION: A communication device includes: first communication means for performing communication using a first communication mode; second communication means for performing communication using a second communication mode differing from the first communication mode; and control means that in the case of changing a communication path for the first communication mode in a state in which first communication connection using the first communication mode and second communication connection using the second communication mode are established for communication connection with an external device, performs control on the second communication means so as to transmit a determined request to the external device using the second communication connection and performs control so as to establish third communication connection with the external device having a changed communication path for the first communication mode.SELECTED DRAWING: Figure 3 【課題】通信装置間の通信接続を維持しながら、通信経路を変える通信装置、通信システム、通信装置の制御方法、及び、プログラムを提供する。【解決手段】通信装置は、第１の通信方式で通信する第１の通信手段と、第１の通信方式とは異なる第２の通信方式で通信する第２の通信手段と、外部装置との通信接続に第１の通信方式を使用する第１の通信接続と第２の通信方式を使用する第２の通信接続とがある状態で第１の通信方式の通信経路を変更する場合、定められた要求を第２の通信接続によって外部装置に送信するよう第２の通信手段を制御し、第１の通信方式の通信経路が変更された外部装置との第３の通信接続を確立するよう制御する制御手段と、を有する。【選択図】図３
