FIG. 2 is a flow chart showing the procedure of the incoming call notification method of the present invention. The operation of this embodiment will be described below with reference to FIGS. 1 and 2.

In FIG. 1, when the subscriber of the mobile telephone 1 on the calling side calls the subscriber of the mobile telephone 7 on the called side, the exchange 3 uses the HLR 4 based on the dialed number (the number of the mobile telephone 7 on the called side). Inquire whether or not you have a mail arrival notification service. The HLR 4 searches the subscriber data based on the dialed number and reports to the exchange 3 whether or not the mail arrival notification service is held. The exchange 3 sets and holds the information in the call information memory 31.

When the mobile telephone 7 on the called side is in a call-disabled state or when the calling subscriber disconnects without receiving a response from the called subscriber, the exchange 3 makes a mail arrival notification request to the mail server 5 according to the called subscriber status. An announcement or a predetermined tone is connected to the mobile phone 1 on the calling side. In case of disconnection of the calling subscriber without the answer of the called subscriber, the calling subscriber is released.

Next, the details of the operation will be described with reference to FIG. In the exchange, when the mobile phone of the called side is out of range / powered off or there is no response during the connection process, the release process is performed (step 1: S1 in FIG. 2, referred to as S1, hereinafter the same), and the mobile phone of the called side is registered in advance. On the other hand, it is confirmed whether or not the incoming call notification condition indicating the notification applicable category is unconditional notification (S2). In the case of an unconditional notification, an incoming mail notification request is immediately sent to the mail server (S5). If it is not an unconditional notification, the reason why the call cannot be received is checked. If the call is out of service area, power is turned off, or the like (S3), Whether or not the notification service is added is confirmed (S4), and if the notification service is added, a mail arrival notification request is sent to the mail server (S5). In the process of S4, whether or not the mobile phone 7 on the receiving side has the mail arrival notification service is checked by checking the inside of the call information memory.

In the mail incoming notification request, the telephone numbers of the mobile phone 1 on the outgoing side and the mobile phone 7 on the incoming side are reported to the mail server. At this time, an announcement or tone is connected to the mobile phone 1 on the calling side. In the process of S3, if the mobile phone of the calling side is disconnected without the response of the mobile phone of the receiving side, the calling subscriber is released (S6).

When the mail server receives the mail transmission request, the mail server requests the HLR to convert the telephone number into a mail address by the telephone number of the called subscriber. That is, based on the incoming mail notification request and the telephone number of the called subscriber 20, the HLR makes a conversion request from the telephone number to the mail address (S11), receives the conversion result (S12), and confirms the received mail address. Check (S13). If the mail address is registered, the outgoing number and the incoming time when the incoming call cannot be received received from the exchange are edited as the mail contents (S14), and the mail is sent to the registered destination mail address (S15). .

The HLR converts a telephone number into a mail address and reports the mail address to the mail server. That is, the subscriber data is searched from the requested telephone number, the registered mail address is retrieved (S21), and the retrieved mail address is reported to the mail server (S22).

As described above, when the notification destination e-mail address when the incoming call is impossible is the address of the mobile phone on the receiving side, when the mobile phone recovers from the incoming call disabled state, the subscriber checks the mail and receives the incoming call during that time. It becomes possible to know. Further, when the mail address is another address, for example, a personal computer in the office of work, it is possible to know the incoming call even if the mobile phone is not there. As an incoming call notification condition, unconditional notification is set or notification is made when the status of the mobile wireless terminal on the called side is out of range or the power is off. The registration of the incoming call notification condition is arbitrarily performed by the subscriber setting.

In the above-described embodiment, the mail address of the notification destination is managed by the HLR, and the mail server is configured to know the transmission destination address by inquiring the mail address to the HLR at the time of mail transmission. By providing the conversion data from number to mail address and the search function on the mail server side, it is not necessary to access the HLR from the mail server for mail address conversion when sending mail, and it is expected to reduce the load on the network. it can.
