Multimode wireless communication apparatus and high frequency integrated circuit therefore

Abstract

A multimode wireless communication apparatus including a radio frequency unit having controllable communication mode and a control unit for periodically making the radio frequency unit operate in a mobile telephone mode and, after predetermined time, switching the mode to a wireless LAN mode, wherein if occurrence of an incoming call event is detected when the radio frequency unit is in standby reception in the mobile telephone mode, the control unit suppresses the switching to the wireless LAN mode and determines whether the communication in the mobile telephone mode should be continued or not.

1 . A multimode wireless communication apparatus comprising:
 a radio frequency unit having controllable communication mode; and   a control unit for making said radio frequency unit operate periodically in a first communication mode and, after predetermined time interval, switching from the first communication mode to a second communication mode, and   said control unit includes determining means for suppressing the switching of said radio frequency unit to the second communication mode when occurrence of a predetermined event is detected from a signal received during a period in which said radio frequency unit is operating in the first communication mode and determining whether communication in the first communication mode should be continued on or not.
