Abstract
An exemplary mobile phone is for determining a using state of each of other mobile phones communicatively connected with the mobile phone. The mobile phone includes a first communicating unit, a power switch, a using state determining unit, a second communicating unit, and a control unit. The using state determining unit determines the using state of the mobile phone by monitoring the first communicating unit and the power switch. The control unit controls the second communicating unit to transmit a contact ID and the using state of the mobile phone to a mobile switching center (MSC) via a base station (BS). Each one of the other mobile phones obtains the using state of the mobile phone from the MSC by transmitting the contact ID of the mobile phone via the BS, and updates the using state of the contact ID in the address list with the obtained using state.
