To provide a communication system in which a transmission-side communication terminal device can transmit data by designating an area where a reception-side communication terminal device is located by direct wireless communication method.SOLUTION: A first communication terminal device 31 (1) transmits, by direct wireless communication method, data to which a communication identifier yyy corresponding to a specific management area located around the current position of the first communication terminal device is added as a transmission-destination communication identifier. A second communication terminal device 31 (2) makes received data usable in an application if the transmission-destination communication identifier yyy added to the received data by direct wireless communication method coincides with a communication identifier corresponding to a management area including the current position of the second communication terminal device 31 (2).SELECTED DRAWING: Figure 2 【課題】送信側の通信端末装置が、直接無線通信方式により、受信側の通信端末装置が位置しているエリアを指定してデータを送信することができる通信システムを提供する。【解決手段】第１の通信端末装置３１（１）は、その第１の通信端末装置の現在位置の周辺に位置する特定の管理エリアに対応する通信識別子ｙｙｙを送信先の通信識別子として付加したデータを、直接無線通信方式によって送信する。第２の通信端末装置３１（２）は、直接無線通信方式によって受信したデータに付加されている送信先の通信識別子ｙｙｙが、その第２の通信端末装置３１（２）の現在位置を含む管理エリアに対応する通信識別子に一致している場合に、受信したデータをアプリケーションで使用可能にする。【選択図】図２
