Abstract: A wireless communication device receives a message periodically broadcast by a wireless broadcast device placed within a location, and determines a type of the location and a broadcast period of the message. The wireless communication device sets a check period for periodically checking whether the wireless communication device receives the message, and checks if a present alert mode of the wireless communication device is suitable for the type of the location in a present check period. When the present alert mode of the wireless communication device is not suitable, the wireless communication device automatically switches the present tone mode to a new tone. When the wireless communication device does not receive the message within a next check period, the wireless communication device is determined as having left the location and automatically switched back to the present alert mode from the new alert mode.

Abstract: A communication method is used for a mobile phone. The mobile phone is capable of receiving a first subscriber identity module (SIM) card and a second SIM card. The mobile phone acquires a first paging reception time of the first SIM card and a second paging reception time of the second SIM card, and further calculates a minimum time gap between the first paging reception time and the second paging reception time. If the minimum time gap is less than a threshold time gap, the mobile phone modulates the first paging reception time and the second paging reception time, such that the minimum time gap is not less than the threshold time gap.
