The invention provides a system and method for realizing the calling of dual mode mobile phone by using an intelligent network. After the service user becomes a subscriber for calling process and called process in the intelligent network, when the dual mode mobile phone enters the work range of the access point device, the access point device dials to the service switch point device, triggers a service of the service control point device, and records a number of the access point device, a number of the dual mode mobile phone and the information of the mobile phone registered in the access point device. When the dual mode mobile phone moves out of the work range of the access point device, the access point device dials and triggers a service of the service control point device through the service switch point device, and the registration is released. The dual mode mobile phone makes a call out after registering, and the access point device changes the calling number and dials to the service switch point device to trigger the process of the service control point device. The process takes the number of the dual mode mobile phone as the calling number in the connection message, and connects the calling party and the called party. The calling party dials the number of the dual mode mobile phone and triggers the process of intelligent network at the service control point device, and the process changes the number and joints to the dual mode mobile phone through the service switch point device and the access point device. The dual mode mobile phone of the invention can communicate with any telephone in the existing communication networks without using its home wireless network.
