Abstract
The present invention provides a telecommunication system, a mobile phone and a calling method adapted for the telecommunication system. The telecommunication system includes a mobile phone connected to a wireless network and a wired phone connected to a wired network. The mobile phone and the wired phone communicate each other within a predetermined coverage area. When there is not a wired phone within the predetermined coverage area or there is a wired phone within the predetermined coverage area and the current state of the wired phone is busy, the mobile phone makes a call via the wireless network. If there is a wired phone within the predetermined coverage area and the current state of the wired phone is idle, the mobile phone sends a phone number to the wired phone, and the wired phone makes the call via the wired network.
