    • A telephone number change notification method is provided in which a calling party is reliably identified when a new telephone number of a called party is notified to the calling party when the called party changed the telephone number. When a telephone exchange (2) detects (102) that a called number is changed based on a subscriber information database, the telephone exchange sends a prompt message (103) asking for sending a telephone number notification request to a calling telephone. The calling telephone creates a digital signature (104) and sends it to the telephone exchange (2). The telephone exchange (2) forwards it (105) to a new telephone number of a called telephone (1-2). The called telephone (1-2) receives the digital signature and verifies it (106). If the digital signature is valid, the called telephone notifies a new telephone number (107) to the calling telephone (1-1).
    • 提供一种电话号码变更通知方法,其中当被叫方更改电话号码时,当被叫方的新电话号码被通知给主叫方时,主叫方被可靠地识别。 当电话交换机(2)基于用户信息数据库检测到(102)呼叫号码被改变时,电话交换机向呼叫电话发送请求发送电话号码通知请求的提示消息(103)。 呼叫电话创建数字签名(104)并将其发送到电话交换机(2)。 电话交换机(2)将其(105)转发到被叫电话(1-2)的新电话号码。 被叫电话(1-2)接收数字签名并进行验证(106)。 如果数字签名有效,被叫电话将通知新的电话号码(107)给主叫电话(1-1)。

    • An object of the present invention is to provide a communication apparatus capable of being connected to a communication line through which calling party information comes at the time of termination, wherein without bothering a user, it is possible to perform display of incoming call history, automatic dialing origination by using the display. In the communication apparatus, when a calling party information receiving section (6) receives calling party information, a main controlling section (10) reads the calling party information out of a specific area of a memory (8), and sequentially compares the calling party information received by the calling party information receiving section (6) with the read calling party information. In the case where it is judged that they are not coincident with each other, the calling party information received by the calling party information receiving section (6) and the incoming call date and time thereof are associated with each other and stored in an incoming call history area of the memory (8), and then the communication apparatus goes into a telephone answering mode. In the case where it is judged that calling party information coincident with the received calling party information is read out of the specific area of the memory (8), the communication apparatus goes into the telephone answering mode at once.
