To provide a communication device or the like that can prevent messages to be frequently transmitted regardless of a cycle to detect whether the communication device is in the inside of a communication service area or the outside of the communication service area.SOLUTION: A communication device determines that a communication state is changed from the inside of a communication service area to the outside of the communication service area, or the communication state is changed from the outside of the communication service area to the inside of the communication service area, and gives notice of information indicating change in the communication state if it has determined that the communication state is changed. If it has determined that the communication state is changed although it has not been moved since it gave notice of the information indicating the change in the communication state, it does not notify a user of the information indicating change in the communication state.SELECTED DRAWING: Figure 2

    【課題】通信圏内と通信圏外の検知周期に関わらず、頻繁にメッセージが通知されることを防ぐことが可能な通信装置等を提供する。【解決手段】通信圏内から通信圏外に通信状態が変化したこと、又は通信圏外から通信圏内に通信状態が変化したことを判定し、通信状態が変化したと判定した場合に通信状態が変化したことを示す情報を通知するが、前回通信状態が変化したことを示す情報を通知してから、移動していないにも関わらず通信状態が変化したと判定した場合には、通信状態が変化したことを示す情報をユーザへ通知しない。【選択図】図2
