When an incoming voice call is detected, a mobile phone 100 judges whether an application that coordinates multicast service and unicast communication is running. If the application is not running, the user is notified of incoming voice calls. On the other hand, if in an application running state, priority mode setting information 1041 is referenced and data cell priority mode is judged. If judged to be in data call priority mode, data communication is continued without notifying the user of the reception of incoming voice calls. On the other hand, if judged to be in voice call priority mode, the user is notified of incoming voice calls.
