Abstract
The present invention relates to a handover method for a dual band/dual mode mobile communication terminal between a synchronous mobile communication network and an asynchronous mobile communication network. The method includes the first step of the main processor setting an initial mobile communication network connection to the asynchronous mobile communication network and connecting to the asynchronous mobile communication network when power is applied; the second step of activating the synchronous RF device and setting up a connection to the synchronous mobile communication network when the intensity of a signal from the asynchronous mobile communication network is equal to or lower than a first predetermined reference value; the third step of determining whether the intensity of a signal from the asynchronous mobile communication network is equal to or lower than a second predetermined reference value previously set for the handover; the fourth step of activating the connection to the synchronous mobile communication network set up at the second step if the intensity of the signal from the asynchronous mobile communication network is determined to be equal to or lower than the …
