BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone exchange connection method, and more particularly, to a mobile telephone exchange connection method for an incoming call in a state where a mobile terminal cannot receive an incoming call due to a power failure or out of service area.

[0002]

2. Description of the Related Art A conventional mobile telephone exchange connection method will be described with reference to the drawings.

FIG. 7 is a schematic configuration diagram of an automobile telephone exchange showing an example of a conventional mobile telephone exchange system.

In FIG. 7, this conventional example is disclosed in
No. 170573, which shows an automatic transmission device 117
When there is an incoming call from the calling subscriber A to the car telephone subscriber B outside the service area SA, and when the calling subscriber A desires the callback, the telephone number and the timer 115 for the callback are requested. The measured incoming time is recorded in the incoming call recording device 114, and thereafter, when the mobile phone subscriber B enters the service area SA, the telephone number and the incoming time are notified to the mobile phone subscriber B. If car telephone subscriber B wants to talk directly to calling subscriber A, he calls subscriber A using the telephone number recorded in incoming call recording device 114, otherwise this telephone number is used. After calling the calling subscriber A, the mobile telephone subscriber is notified that it has entered the service area SA.

FIG. 8 is a flow chart for explaining the incoming call record sending process in the conventional example shown in FIG.

[0008] In FIG. 8, particularly in the conventional example, the automatic transmission device 117 monitors the home memory 113 at any time as to whether or not the mobile telephone subscriber B has moved from outside the service area SA into the service area SA (step S 1). S2
1) When recognizing that the mobile telephone subscriber B has moved into the service area SA, the mobile telephone subscriber B is called, and then the telephone number from the calling subscriber A recorded in the incoming call recording device 114 and The incoming call time is converted into a voice message signal by the voice message device 114 and transmitted to the mobile phone subscriber B as a voice message (step S22). When the mobile telephone subscriber B wants to call the calling subscriber A and talk directly, the mobile telephone subscriber B transmits a specific dial tone signal (DTMF signal) such as “#” to the mobile telephone exchange 110. Car telephone exchange 11
0, upon receiving the dial tone signal from the car telephone subscriber B, automatically calls the calling subscriber A according to the telephone number recorded in the incoming call recording device 114 (steps S23, S24). Thereby, the mobile telephone 133 of the mobile telephone subscriber B and the telephone 121 of the calling subscriber A are automatically connected.

[0007]

In the conventional connection method for mobile telephone exchange, if the called party is in a state of being unable to accept an incoming call and there is an incoming call, the called party will not receive the call-back desired number. There is a problem that the caller cannot talk to the called party unless he / she always wants to be aware of the call back even if the called party cannot receive the call because the power is turned off because the method cannot connect with the calling party. .

Further, when the called party moves into the service area and hears an incoming voice message from the exchange, in order to consciously talk with the calling party, a specific number must be transmitted before the calling party can communicate with the calling party. There is a problem that it cannot be connected.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a mobile telephone switching system according to an embodiment of the present invention.

Referring to FIG. 1, the mobile telephone switching system according to the present embodiment includes a switching equipment (GS) 1 for accommodating a telephone set via a fixed network and a mobile equipment via radio, and this switching equipment (GS) 1 Is the phone and mobile device to be accommodated
Subscriber registration information and the current status of each mobile device
Subscriber data , including information on the acceptability of incoming calls at the point, and communication with the destination for that call when a call is detected.
Call connection status information including talk connection possible, completed, disabled and hold
To the subscriber data accommodating device (HLR) 2 and the exchange (GS) 1 for storing various telephone services in which the caller and the called party are registered (for example, an incoming call for an incoming call received when the called party cannot receive a call). Service control station (SCP) 3 which issues processing instructions for outgoing calls and incoming calls, and a guide corresponding to the connection processing process to callers and callees by voice according to a response processing service when possible. Audio device (I
P) 4 is connected to an exchange network.

Next, the operation of the embodiment of the present invention will be described with reference to FIG.

As an example, a description will be made assuming a general call in which Mr. A calls Mr. B. (However, the callee B at this time is a mobile terminal.) The caller (A) dials the number of the callee (B).

When the exchange 1 reads out the subscriber information of the called party (B), if it is out of service area or the power is turned off, it refers to the registration bit of this service, and if it is this service subscriber, it reads the subscriber data accommodating device 2 Caller (A) responds to called party (B)
To set a "call hold bit" indicating that the call is on hold.

The exchange 1 notifies the service control station 3 that there has been a call that did not result in a call.

For the caller (A), a special guidance is heard from the voice device 4 and the call is temporarily terminated.

When the first called party (B) moves to a place where radio waves can reach or turns on the power and enters a state in which a call can be made, location registration is executed. At that time, the exchange 1 inquires of the subscriber data accommodating device 2 whether or not the subscriber is the service subscriber.

When the subscriber is the service subscriber and the "call hold bit" is set, the exchange 1 notifies the service control station 3.

The service control station 3 instructs the exchange 1 to call the called party (B).

When the called party (B) answers, the service control station 3 instructs the exchange 1 to call the calling party (A).

When the caller (A) answers, the caller (A) and the callee (B) enter a call state. If the caller (A) does not respond and the response times out, the exchange 1 notifies the service control station 3. The service control station 3 instructs the called party (B) to hear the guidance from the audio device 4. Further, after a certain period of time (settable / changeable), retry processing for connection is performed.

FIG. 2 is a flowchart showing a process of the exchange at the time of an incoming call according to the present embodiment, FIG. 3 is a flowchart showing a process of the exchange at the incoming call having an incoming call, and FIG. Sender in form (A)
FIG. 5 is a sequence diagram showing a first connection process from the first to the called party (B), FIG. 5 is a sequence diagram showing a second connection process following the first connection process shown in FIG. 4, and FIG. 6 is a sequence diagram showing the second connection process shown in FIG. It is a sequence diagram which shows the last 3rd connection process following the 2nd connection process.

Next, the sender (A) in the present embodiment
The operation of connection from the user to the called party (B) will be described in detail with reference to FIGS.

When an address (IAM) signal is transmitted from the communication carrier to which the caller (A) belongs to the gateway exchange (GS) 1 of the communication carrier to which the called party (B) belongs, the received GS
1 reads out incoming information from the HLR 2 (S2). At this time, the out-of-service area (or power-off) of the called party (B) can be detected (S3). Next, it is determined whether the called party B is a service subscriber (S4). When Callee B is a Contractor (S
5), GS1 is HLR2, sender (A) is receiver
A MAP signal for setting a "call hold bit" indicating a hold state is transmitted to (B) (S6).
The GS 1 that has received the response signal from the HLR 2 notifies the service control station 3 that there is a response hold call (S
7). The SCP 3 instructs the GS 1 to ask the caller (A) for the dedicated guidance via the IP 4 (S
8). The caller (A) who has heard this guidance goes on-hook and temporarily terminates the call (S9).

Next, when the location of the first called party (B) is registered (S11), GS1 makes an inquiry to HLR2 (S12). The HLR 2 notifies the GS 1 when the subscriber is the service subscriber and the “call hold bit” is set (S 13). GS1 notifies SCP3 (S1
4). SCP3 instructs GS1 to call subscriber (B) (S15). When the subscriber (B) responds (S16), the GS1 notifies the SCP3 that it responded. SCP3 instructs GS1 to hear dedicated guidance from IP4. GS1 is a subscriber (B)
Guidance is sent from IP4. At the same time, S
CP3 calls GS1 to call subscriber (A),
An instruction is issued (S17). When the subscriber (A) answers (S
18) The subscriber (A) is made to listen to the dedicated guidance in the same sequence as the subscriber (B) (S19,
S20). When both the subscriber (A) and the subscriber (B) have finished listening to the guidance, they are in a talking state with each other. The disconnection process is the same as the existing sequence (S20).

As described above, in the present embodiment, a subscriber who receives this service for connection to an incoming call whose call cannot be accepted will move to a place where power cannot reach, for example, an answering machine service. You do not need to do anything to start the service when you say that, and to stop the service when you return to the place where radio waves reach, so once you apply at the service window,
Service users can receive this service without awareness. As a result, even when the service user goes out of the area without noticing, the service can be received without any special operation. Further, even if the user has intentionally wished to connect to the answering service while driving a car, this service can be realized by turning off the power of the terminal.

For example, if the power of the terminal is turned on again when the driving of the automobile is completed, a call (actually from an exchange) is received from the other party who came in when the power was turned off.

Further, the number of incoming calls to be stored can be set and changed by the user declaring. In addition, when there is no response when the caller (A) is called, the user can set how many times to retry by reporting.

[0031]

As described above, according to the present invention, in an exchange accommodating a plurality of telephones via a fixed network and a plurality of mobile units via radio, the exchange provides a predetermined telephone service to be provided. If a call is made from the telephone to a mobile device that is out of the wireless service area or is in a state of rejection of incoming calls due to power outage, the outgoing telephone is stored as incoming call hold, the call is temporarily terminated, and The following effects can be obtained by calling the outgoing telephone and the mobile device in the incoming call acceptable state when detecting that the mobile device in the non-acceptable state has entered the incoming call acceptable state, and connecting the two when the call is answered. Can be.

The first effect is, for example, while riding a subway.
When a call that cannot be reached due to lack of radio waves becomes available, the user does not need to take any action (even if the user has not been informed that he was out of reach of radio waves). become able to. This allows the called party to be aware that he or she is out of reach of the radio wave, check the contents of the answering machine assuming that there may have been a call to him during that time, or send the call to that person. Or need to be done. Also, there are no cases in which the caller has not given up many times and has given up.

The reason is that a call which did not reach from the telephone of the caller (A) to the mobile station of the callee (B) is stored in the exchange located therebetween.

A second effect is that no operation such as an answering service is required at all. As a result, operations such as service start / stop are not required as in the past, so that even if the user goes out of the service area without noticing, the user can receive the service.

The reason is that the caller (A) of the telephone does not know that the called party (B) of the mobile device is ready to talk again, but only the exchange located in the middle knows. This is because the switching equipment activates both the telephone of the caller (A) and the mobile device of the receiver (B).
