The location registration information is updated, and the incoming call record information is transmitted from the incoming call information management server in an electronic mail (e-mail) format.

On the other hand, in the portable terminal (specific subscriber), the fact that the own terminal has requested the incoming call recording is registered by dialing the special number for incoming call recording request. When requesting record of incoming call, when it moves from outside the service area to within service area or when the power is turned on, if it is within service area, the call record inquiry signal (also serving as location registration request) is automatically sent to the center side. To do. Call record information from the center (e-mail format)
When is received, the fact that there is an incoming call is edited and displayed. Therefore, when the user enters the service area or turns on the power, it is possible to obtain an immediate effect that the user can be notified that there is an incoming call.

Further, as a feature of the present invention, as a method for canceling a request for incoming call recording, manual release by dialing a special number for incoming call record request cancellation from a portable terminal, automatic cancellation when a designated time elapses on the center side, or incoming call record distribution is used. Automatic release is used. Further, it is possible to specify which method is used when canceling the incoming call recording request special number on the mobile terminal.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, the mobile communication system of this example includes a mobile terminal 1 that is a subscriber that can move arbitrarily.
It accommodates the mobile terminal 1 in the wireless zone 21 formed by itself and the wireless base station 2 that can be connected by a wireless line, the wireless base station 2 as one of the nodes of the mobile communication network, and is also a center for recording incoming calls. The mobile communication exchange 3, the subscriber database (HLR) 4 connected to the mobile communication exchange 3 for registering information of each subscriber (information regarding operation and status, other management information), and the mobile communication exchange 3 An incoming call information management server 5 which is connected to the subscriber and manages incoming call information to the subscriber, and a voice which is connected to the mobile communication exchange 3 and stores a voice message from the caller when the incoming call is received by the subscriber whose incoming call is being recorded. The storage device 6 is provided with a mail server 7 that is connected to the mobile communication switching system 3 and the packet network to send and receive electronic mail.

Although only one mobile terminal 1, radio base station 2, mobile telecommunications switching system 3 and the like are shown in FIG. In addition, the mobile telecommunication switch 3 is a wired public telephone network (PSTN).
The mobile terminal 1 is connected to another mobile terminal or P
It is possible to communicate with other terminals accommodated in the STN.

FIG. 2 is a block diagram showing a configuration example of the mobile terminal 1. In FIG. 2, the mobile terminal 1 of the present example has a signal encoding / decoding and modulation / demodulation function, and the antenna 1
1 has a wireless unit 12 for wirelessly transmitting and receiving data and voice information to and from the wireless base station 2, a call unit 14 for inputting and outputting voice information, and a display such as an LCD for the user. A display unit 15 for visually displaying character information and the like, an operation unit 16 having a push-button switch (key) and the like for inputting various instruction information from a user, and a power supply unit 17 for supplying power to each unit in the terminal. , And a control unit 13 having a CPU and a memory to control each of the above units.

The mobile communication system of the present invention is provided with an incoming call information management server 5 in a generally known mobile communication system such as a PDC system or a CDMA system. Under the control of the mobile communication exchange 3, the incoming call information management server 5 records an incoming call to a specific subscriber (mobile terminal 1) requesting the incoming call record and makes an inquiry about the incoming call record. In this case, the mail server 7 instructs the mail server 7 to send the incoming call record information to the specific subscriber in the electronic mail format.

A special number (for example, "1419") is set to instruct to record the incoming call so that the center facility (mobile communication exchange 3) can detect the incoming call request from the specific subscriber (portable terminal 1). I'll do it. When the mobile communication exchange 3 receives this special number, it identifies that the specific subscriber requests the incoming call record, and informs the HLR (subscriber database) 4 that the specific subscriber requests the incoming call record. Record.

On the contrary, a special number (for example, "1418") for instructing to cancel the request for recording the incoming call is also set.

On the other hand, the portable terminal 1 which is a specific subscriber is connected to the mobile communication exchange 3 through the radio unit 12 and the radio base station 2 under the control of the control unit 13 and receives an incoming call by the key input operation of the operation unit 16. By dialing (transmitting) the special number “1419” of the recording request, the fact that the own terminal has requested the recording of the incoming call is recorded in the memory in the control unit 13. In a state where this incoming call record is requested, an incoming call record inquiry signal (position information signal forcibly transmitted) is automatically transmitted at the time of moving from the outside of the service area to the service area or at the time of turning on the power in the service area. After the incoming call record inquiry, the incoming call record information (e-mail format) is received, and the fact that there is an incoming call is edited by the control unit 13 and displayed in characters on the display unit 15. When the special number "1418" for canceling the incoming call recording request is dialed (transmitted), the record requested by the own terminal in the memory in the control unit 13 is deleted.

Next, the operation of this embodiment will be described.

A user of a mobile terminal 1 (subscriber)
Before the electric wave stops reaching the underground, or before the power is turned off for a train, a meeting, a hospital, etc., the operation unit 16 is operated to dial the special number for incoming call recording request (“1419”).

The mobile telecommunication exchange 3 receives this via the wireless base station 2, accepts the "incoming call record request", and
It requests the LR4 to record the "incoming call recording request" status.

In this state, when there is an incoming call from the PSTN or the like to the mobile communication exchange 3 to the corresponding subscriber (portable terminal 1), the mobile communication exchange 3 attempts a normal connection (calling) and also the HLR 4 You can also access and request information about the subscriber. If the subscriber is a “call record request”, the status is also read.

The subscriber does not answer the call because it is out of range or power is off.

The mobile telecommunication exchange 3 recognizes the "incoming call record request" state from the information read from the HLR 4, and instructs the incoming call information management server 5 to record the incoming call of this call in the "incoming call record request" state. The contents of the incoming call record include a corresponding subscriber number (incoming subscriber number), a calling subscriber number, date and time, and the like. If the calling subscriber number has not been received (non notification, etc.), leave it blank.

The incoming call information management server 5 records these pieces of information.

When the relevant subscriber moves from outside the service area to within the service area or when the power is turned on, if the service area is within the service area, an incoming call record inquiry signal (position registration signal) is automatically transmitted. In addition,
In a normal system, the location registration signal is sent when you move in the management area, and when the management area does not change, such as when you go in and out of the underground, the location registration signal is sent. Is not done. However, in the present invention, even in such a case, the position registration signal (incoming call record inquiry signal) is automatically transmitted.

When the mobile communication exchange 3 receives this position information registration signal through the radio base station 2, it sends the information to the HLR 4 for updating.

The HLR 4 adds the "incoming call record request" state to the response signal to the HLR 4 and sends the response signal to the mobile communication switching system 3.

The mobile telecommunications switching system 3 identifies that the subscriber is in the "incoming call record request" state and instructs the incoming call information management server 5 to retrieve the incoming call record by using the corresponding subscriber number as a key. .

As a search result, the incoming call information management server 5 records the corresponding subscriber number, calling subscriber number, and
Information such as date and time is edited in an electronic mail format and sent to the mail server 7. In addition, "incoming call history" is specified as the title of this e-mail. Also, the electronic mail address of the corresponding subscriber has been converted based on the corresponding subscriber number when the mobile communication exchange 3 previously accessed the HLR 4.

The mail server 7 sends the received information (e-mail) to the corresponding subscriber through the mobile communication exchange 3 and the wireless base station 2.

The subscriber (portable terminal 1) receives this e-mail in the same manner as general e-mail. Mobile terminal 1
Identifies the title "incoming call history" of the e-mail, distinguishes it from general e-mail, and regards it as an incoming call record notification, reads out the calling subscriber number, date and time, etc. from the body of the e-mail, and displays on the display unit 15
Incoming call is displayed on the screen. From this display, the user can know the incoming call whose communication is not possible and can take appropriate action.

When the subscriber (portable terminal 1) no longer needs to record the incoming call, the user operates the operation unit 16 to dial a special number ("1418") for canceling the incoming call request.

The mobile telecommunications switching system 3 receives this through the radio base station 2 and instructs the HLR 4 to cancel the "incoming call record request" state. Since the HLR 4 does not have the "incoming call record request" state as the information of the corresponding subscriber, the subsequent incoming call to the corresponding subscriber is treated as a normal incoming call.

By connecting a message center equipped with a voice response device / voice editing device to the mobile communication exchange 3, a call can be made from a general telephone terminal to the message center and the incoming call history can be confirmed by voice. be able to.

Next, another embodiment of the present invention will be described.

The above-described embodiment (first embodiment)
In order to cancel the call recording request, a method of dialing a special number by the user's manual operation from the corresponding subscriber (mobile terminal 1) side was used, but an unnecessary "call recording request" state remains for a long time. In order to avoid such a situation, in the embodiments described below, in addition to the manual release by the special number dial, an automatic release method is used.

The second embodiment has a basic configuration shown in FIG.
It is similar to the first embodiment shown in FIG. At the incoming call recording center (mobile communication switch 3), after receiving the incoming call record request special number ("1419"), a predetermined time (for example, 12 hours) elapses, and then the call is automatically released. Specifically, the HLR 4 is provided with a timer for measuring a predetermined time set in advance,
"Record incoming call required" as information of the corresponding subscriber (mobile terminal 1)
After registering the status, the timer is started, and after a certain period of time, the registration of the "incoming call record request" status is canceled. Also,
The portable terminal 1 is also provided with a similar timer, and when a certain time has elapsed after the self terminal requested the automatic cancellation, the self terminal in the memory in the control unit 13 erases the record that the self terminal requested the incoming call recording. The fixed time may be fixedly designated in advance, or may be arbitrarily designated by the user at that time, as described later.

The basic configuration of the third embodiment is also shown in FIG.
It is similar to the first embodiment shown in FIG. After the incoming call record inquiry signal (position registration signal) is received at the incoming call record center (mobile communication switch 3), the incoming call record of the corresponding subscriber (mobile terminal 1) is searched, and if there is an incoming call record, it is distributed. ,
If there is no incoming call record, it will be automatically canceled as it is. Specifically, when the HLR 4 receives a position information registration signal for updating the registration information of the corresponding subscriber from the mobile communication exchange 3, the HLR 4 adds the "incoming call record request" state to the response signal to that. After transmitting to the mobile communication switchboard 3, the registration of the "incoming call record request" state is canceled. In addition, after the incoming call inquiry signal is transmitted, the portable terminal 1 records the incoming call record requested by its own terminal in the memory in the control unit 13 when the time required for receiving the incoming call record has passed with sufficient margin. to erase.

In yet another embodiment, the basic configuration is the same as that of the above-mentioned embodiment, but when the special number ("1419") of the incoming call record request of the subscriber (portable terminal 1) is dialed, the second configuration is performed. Also, it is possible to specify to cancel the incoming call recording request by one or both of the methods of automatically canceling the incoming call recording request shown in the third embodiment.

Specifically, the incoming call recording center (mobile communication switching system 3) sends an incoming call record request special number ("1419").
At the time of acceptance of the request, the corresponding subscriber (mobile terminal 1) is inquired as to whether or not there is optional information that specifies the condition for automatically canceling the incoming call recording request (a message prompting the input of the optional information is transmitted to the display unit 15 of the portable terminal 1). Then, the corresponding subscriber (user) operates the operation unit 16 as necessary to additionally transmit the option information. This optional information (conditions for automatic cancellation) means whether or not to automatically cancel after a certain period of time has passed, and how many hours is the certain period of time in that case, whether to automatically cancel when the incoming call record inquiry signal (position registration signal) is transmitted. This is information that specifies whether or not. Upon receipt of this optional information, the mobile switching center 3 transmits it to the HLR 4 and records it as the information of the corresponding subscriber. According to this record, the HLR 4 monitors whether or not the condition for automatically canceling the incoming call recording request is satisfied, and when it is satisfied, the HLR 4 automatically cancels by the method described above.

[0044]

According to the present invention, when a mobile terminal (portable terminal) that is in a communication-disabled state enters the service area, is turned on, or that there is an incoming call during a communication-disabled state, it can be immediately notified. . In addition, since it is possible to automatically cancel the incoming call recording request, it puts an extra load on the system,
It is possible to prevent unnecessary charges.
