Abstract

PROBLEM TO BE SOLVED: To effectively utilize a PHS slave unit as an original use shape by allowing an exchange network to detect a transmission operation of a telephone number or transmission operation of the PHS slave unit of a calling side customer owned and maintained base station, to notify the customer-owned-and-maintained base station of an incoming call of the transmission operation when the customer owned and maintained base station detects the PHS slave unit and to notify a public base station of the incoming call when it does not detect the PHS slave unit. SOLUTION: When a PHS slave unit 5 operates the number of a customer owned and maintained base station 1 with a telephone terminal 7, an exchange network 100 receives a call out. If the station 1 rejects an incoming call when it is a call out by an operation of the station 1, the incoming call is transferred to a public base station where the position registration of the unit 5 is performed, and speech communication processing is started with the response of the unit 5. If incoming call reject is set to a public base station 3 by the public base station where the position registration of the unit 5 is performed when the unit 5 performs a call out via the station 3, a controlling part 100B of the network 100 performs calling to the unit 5 from the station 3 and signals an incoming call to the station 1 when the incoming call reject is not set.

When the switching network detects a calling operation of either the telephone number of the self-operating base station or the telephone number of the PHS handset, the notifying means sets the PHS If the notification of the detection of the slave is notified, the incoming call based on the calling operation is notified to the own base station, while if the notifying means does not notify the detection of the PHS slave, the incoming is notified to the public base station. It is provided with incoming call notification means.
Therefore, the private base station notifies the switching network when it detects a PHS slave, and when the switching network detects a calling operation of either the telephone number of the calling private base station or the telephone number of the PHS slave, When the self-operating base station detects the PHS slave, the incoming call based on the calling operation is notified to the self-operating base station. On the other hand, when the self-operating base station does not detect the PHS slave, the incoming call is notified to the public base station. Notify. Further, the self-operating base station includes a detection unit for detecting whether or not the self-service base station is set to be away, and a notification unit for notifying the switching network of the absence setting when the detection unit detects the absence setting. The network notifies the public base station of an incoming call based on the outgoing operation when the notifying unit notifies the absence setting when the outgoing operation is detected when the notifying unit detects the outgoing operation. It is provided with an incoming call notifying means for notifying the self-managed base station. Accordingly, the private base station notifies the switching network that it is set to be away, and when the switching network detects the call origination operation, it notifies the public base station of an incoming call when the private base station is set to leave. If the private base station is not set to answer, the incoming call is notified to the private base station. Further, the public base station includes a notifying unit for notifying the switching network of the location registration information when the PHS slave unit is detected. An incoming call notifying unit is provided for notifying the public base station of the incoming call based on the calling operation, but notifying the incoming call to the self-operating base station when the notifying unit does not notify the location registration information. Therefore, the public base station is PHS
Upon detecting the slave unit, the switching network notifies the location registration information to the switching network. When the switching network detects the calling operation, if the PHS slave unit is location-registered in the public base station, it notifies the public base station of the incoming call. If the location of the PHS slave is not registered in the public base station, the incoming call is notified to the own base station.

T, antenna AT of PHS slave unit 5, radio unit 51, modem unit 52, channel codec unit 53, audio processing unit 59
By using the microphone 62 and the receiver 63 via the telephone, a call between the user of the PHS slave 5 and the other party is started.

The user of the self-operated base station 1 operates the operation unit 16.
When the destination number is dialed by operating, the control unit 14 detects this calling operation, gives operation information to the line control unit 18, and sends the operation information to the switching network 100 via the line La from the line control unit 18. When the switching network 100 receives the transmission operation information, the switching network 100 calls the other party. Then, when the other party answers, using the microphone 22 and the receiver 23 through the switching network 100, the line La, and the voice processing unit 19 of the own base station 1, a call can be made between the user of the own base station 1 and the other party. Be started.

When the control unit 14 of the base station 1 detects an incoming call from the switching network 100 via the line La and the line control unit 18, the control unit 14 displays an incoming call on the display unit 15 and sounds the buzzer 17 to ring the incoming call. Let it. At this time, if the PHS slave 5 is wirelessly connected to itself, the PHS slave 5 sends the incoming call information to the channel codec unit 13. Then, the incoming call information is modulated by the modem unit 12 and transmitted to the PHS slave 5 via the radio unit 11 and the antenna AT. The incoming information is received by the antenna AT and the radio unit 51 of the PHS slave device 5, and further demodulated by the modem unit 52, and then provided to the control unit 54 via the channel codec unit 53. When the incoming information from the private base station 1 is input, the control unit 54 displays an incoming call on the display unit 55 and causes the buzzer 57 to ring. When either the self-operating base station 1 or the PHS handset 5 performs an incoming call response operation to the incoming call notification, the response operation signal is transmitted to the switching network 100 and the self-operating base station 1 or the PHS handset A call is started between the user who has performed any one of the response operations of No. 5 and the other party.

On the other hand, when the PHS handset 5 is within the range of the public base station 3 shown in FIG. 2 and the user dials the other party number by operating the operation unit 56, the control unit 54 similarly performs this transmission operation. Upon detection, the operation information is transmitted to the channel codec unit 53. Then, the operation information is modulated by the modem 52 and transmitted to the public base station 3 via the radio unit 51 and the antenna AT. When the public base station 3 receives the transmission operation information of the PHS slave unit 5 via the antenna AT and the radio unit 31, it demodulates it with the modulation / demodulation unit 32 and sends it out to the control unit 34 via the channel codec unit 33. When inputting the operation information, the control unit 34 gives the operation information to the line control unit 38. As a result, the operation information is transmitted from the line control unit 38 to the switching network 100 via the line Lb.
When the switching network 100 receives the transmission operation information, the switching network 100 calls the other party. When the other party answers, the switching network 100,
The line Lb, the voice processing unit 39 of the public base station 3, the channel codec unit 33, the modem unit 32, the wireless unit 31, the antenna AT, the antenna AT of the PHS slave unit 5, the wireless unit 51, the modem unit 52, the channel codec unit 53, By using the microphone 62 and the receiver 63 via the audio processing unit 59, a call between the user of the PHS slave 5 and the other party is started.

When the control unit 34 of the public base station 3 detects an incoming call from the switching network 100 via the line Lb and the line control unit 38, the control unit 34 determines whether the PHS slave unit 5 is wirelessly connected to itself. Sends this incoming information to the channel codec unit 33. Then, the incoming information is modulated by the modem 32 and transmitted to the PHS slave 5 via the radio 31 and the antenna AT. This incoming information is received by the antenna AT and the radio section 51 of the PHS slave device 5 and further demodulated by the modem section 52.
To the control unit 54 via In this case, the control unit 5
In step 4, similarly, an incoming call is displayed on the display unit 55, and the buzzer 57 is caused to ring. In response to such an incoming call notification, P
When the incoming call response operation is performed on the HS handset 5 side, this response operation signal is transmitted to the switching network 100 side, and a call between the user of the PHS handset 5 and the other side is started.

The self-operated base station 1 and the PHS slave 5
Are assigned different telephone numbers, and when a caller dials the telephone number of the private base station 1, the switching network 100 generally makes the private base station 1 terminate the call. Thereby, the buzzer of the self-operated base station 1 rings and, when the PHS slave 5 is wirelessly connected to the self-operated base station 1, the buzzer 57 of the PHS slave 5 also rings. However, if the PHS slave 5 is not wirelessly connected to the private base station 1, the PHS slave 5 cannot be called. For this reason, in the present invention, the self-operated base station 1
The switching network 100 determines whether or not the PHS handset has been detected, and if the self-service base station 1 detects the PHS handset 5, the incoming call addressed to the PHS handset is transferred to the self-service base station 1. To P
The HS slave unit 5 is called. In addition, own base station 1
If the PHS slave 5 is not detected, the incoming call addressed to the PHS slave is transferred to the public base station 3 shown in FIG. 2, and the PHS slave 5 is called from the public base station 3.

On the other hand, when the caller dials out the telephone number of the PHS handset 5, the switching network 100 generally makes a call to the public base station 3 shown in FIG. 2 according to the location registration information of the PHS handset 5. That is, in the public base station 3, the PHS slave 5
Is detected, the location registration is performed, and the location registration information is sent to the exchange network 100. Switching network 100
Stores the public base station in which the location of the PHS slave 5 has been registered in the memory 100A as the location registration information of the corresponding PHS slave 5. The switching network 100 is connected to the PHS handset 5 of the caller.
When the above-mentioned dialing of the telephone number is accepted, the incoming call addressed to the PHS slave unit 5 is notified to the corresponding public base station 3 where the location registration was last performed. However, when the PHS slave 5 is already out of the service area of the public base station 3, the corresponding public base station 3 cannot call the PHS slave 5. Therefore, according to the present invention, in such a case, the incoming call addressed to the PHS slave device 5 is transferred to the self-managed base station 1, and the PHS slave device 5
To be called. With such a configuration, the caller transmits the telephone number of the self-operated base station 1 or the telephone number of the PHS child device 5 according to the location of the holder (user) of the PHS child device 5. There is no need to select which phone number to call, no matter which phone number you call.
Can be called.

FIGS. 6 to 8 are flowcharts showing the operation of the main part of the present invention. First, the operation of the control unit 14 of the self-service base station 1 shown in the flowchart of FIG. 6 will be described. The self-managed base station 1 monitors at regular intervals whether or not the PHS slave 5 exists within its own area by activating a slave detection timer for a fixed time. If the slave unit detection timer is not running ("N" in step S1), the PHS slave unit 5 is inquired to determine the presence or absence of the slave unit (step S2). When 5 is detected, it is determined whether or not a slave unit detection flag has been set (step S3). If the detection flag is not set, it means that the PHS slave device 5 has been detected for the first time, and the control unit 14 sets the slave device detection flag in the memory 14A (step S4). The fact that the slave unit has been detected is notified (step S5), and a slave unit detection timer for a fixed time is started (step S6). In addition, PHS
If the slave unit detection flag has already been set when the slave unit 5 is detected, it means that the slave unit 5 is still present in its own area, and the slave unit 5 is not notified to the switching network 100. Only the detection timer is started (step S6).

On the other hand, if the PHS slave unit 5 is not detected, it is determined whether or not the slave unit detection flag has been set (step S7). Has left the service area, and resets the slave unit detection flag (step S8).
After notifying the switching network 100 that a slave unit has not been detected (step S9), a slave unit detection timer is started (step S6). If the PHS slave 5 is not detected and the slave detection flag is not set, it means that the PHS slave 5 does not exist within its own area, and only the slave detection timer is started (step S10). S6).

During the operation of the slave unit detection timer thus activated, the processes in steps S2 to S9 are not executed, but are executed again when the slave unit detection timer expires and becomes inactive. . When the switching network 100 is notified of the non-detection of the slave unit, the switching network 100 sets a rejection of the call to the self-managed base station 1 as described later. Release the call rejection when notified.

Next, irrespective of whether the slave unit detection timer is activated or not, the control unit 14 of the private base station 1 detects the setting of the absence mode and the release setting of the absence mode based on the operation of the operation unit 16, When the answering mode setting operation is detected, and the determination in step S10 becomes "Y", an incoming call rejection is notified by transmitting incoming call rejection data to the switching network 100 in step S11. Also, when the absence operation of the absence mode is detected and the determination in step S10 becomes "Y", step S1 is performed.
In step 1, the call rejection release data is transmitted to the switching network 100 to notify the call rejection release.

Next, FIG. 7 is a flowchart showing the operation of the main part of the control unit 34 of the public base station 3. When the control unit 34 of the public base station 3 newly detects the PHS handset 5, the "position" Is registration information received? "Is determined to be" Y. " In this case, the public base station 3 notifies the switching network 100 of the location registration information of the PHS slave 5 (step S2).
2). As a result, the switching network 100 sets the PHS slave 5 to reject the incoming call as described later.

FIG. 8 is a flowchart showing the operation of the control unit 100B of the switching network 100 in response to the operation of the private base station 1 of FIG. 6 and the operation of the public base station 3 of FIG. The control unit 100B of the switching network 100 receives the location registration information from the public base station 3 and, when the determination in step S31 becomes “Y”, the number of the receiving public base station in the memory 100A and the corresponding PHS slave 5 Step S33 in association with the telephone number
Sets the call rejection flag and sets the handset detection flag. In this case, in the switching network 100, the information of the PHS slaves 5 in the public base stations other than the public base station that last registered the position of the PHS slave 5 is deleted. Further, the control unit 100B of the switching network 100
When notified that the S slave 5 is not detected, the memory 100A
The incoming call rejection flag is set corresponding to the telephone number of the self-managed base station 1 and the handset detection flag is reset. When notified of the detection of the PHS handset 5, the call rejection flag corresponding to the telephone number of the private base station 1 is reset and the handset detection flag is set.

The control unit 100B of the switching network 100
When receiving the absence setting or absence data from the private base station 1, it determines “Y” as “Receive data from private base station?” In step S 32, and in this case, the received data indicates the absence setting Rejected data and step S3
If the determination in Step 4 is “Y”, the call rejection flag is set in correspondence with the telephone number of the self-operating base station 1 in the memory 100A (Step S35). On the other hand, if the received data from the private base station 1 is the incoming call rejection release data indicating the absence setting release and the determination in step S34 is "N", the incoming call rejection flag corresponding to the telephone number of the private base station 1 is reset. (Step S36).

FIG. 5 shows a management table 100C provided in the memory 100A of the switching network 100, in which the control unit 100B performs the processing shown in FIG. 8 and writes information such as an incoming call rejection flag.
FIG. 3 is a diagram showing the configuration of FIG. The management table 100C includes the telephone number of the self-operated base station 1 or the PHS of each public base station.
The presence / absence of detection of the PHS handset 5 via the private base station 1 or each public base station is set in association with the telephone number of the handset 5, and the presence / absence setting of the private base station 1 or the PHS of each public base station is set. The presence / absence of incoming call rejection is set according to the presence / absence of detection of the slave unit 5.

FIGS. 9 and 10 are flowcharts showing the transfer operation of the control unit 100B of the switching network 100 for transferring an incoming call to the PHS handset 5 according to the management table 100C shown in FIG. First, the call receiving operation shown in the flowchart of FIG. 9 will be described. The caller uses the telephone terminal 7 to
It is assumed that the user operates the telephone number of the HS slave unit 5 or operates the telephone number of the own base station 1. Then, the switching network 100
Then, a call based on the operation of the telephone number is accepted (step S41), and it is determined whether the call is a call based on the operation of the telephone number of the own base station 1 (step S4).
2).

Here, the outgoing call of the caller is sent to the own base station 1
In the case of a call based on the operation of the telephone number of
Is determined based on the management table 100C of FIG. 5 (step S43). If the incoming call is rejected, the PHS slave 5 is sent to the public base station whose location is registered. The incoming call is transferred (step S44).
As a result, the PHS slave device 5 is called from the public base station 3, and the call process is started by the response of the PHS slave device 5. If the incoming call rejection is not set for the own base station 1, the incoming call is made to the own base station 1 (step S 45).

If the caller's call is a call through the public base station 3 by dialing the telephone number of the PHS handset 5, the determination in step S42 is "N". In this case, the control unit 100B of the switching network 100 determines whether or not the PHS slave 5 is registered in the public base station 3 and whether or not call rejection is set in the public base station 3 by checking the management table 100C in FIG. (Step S4
6). Here, if incoming rejection is set by the PHS slave unit 5 being registered in the public base station 3, the incoming call is notified to the public base station 3 (step S4).
7) A call is made from the public base station 3 to the PHS slave 5. On the other hand, when the incoming call rejection is not set in the public base station 3, the self-operating base station 1 is notified of the incoming call (step S).
48).

FIG. 10 is a flow chart of the control unit 100B of the switching network 100 showing the call transfer operation to the PHS handset 5 in more detail. When receiving an incoming call addressed to the PHS slave 5 (step S51), the control unit 100B determines whether or not incoming call rejection is set for the public base station 3 (step S52). Here, if the incoming call is rejected by the public base station 3, the incoming call is transferred to the public base station 3, and the PHS slave 5 is called (step S54). In addition, public base station 3
If the incoming call rejection is not set, it is determined whether the incoming call rejection is not set in the private base station 1 and it is determined whether the private base station 1 is detecting the PHS slave 5 (step S53). . If the self-operating base station 1 is not detecting the PHS slave 5, the incoming call is forwarded to the public base station 3 to call the PHS slave 5 (step S54).

Here, when the incoming call is rejected by the public base station 3 (that is, the PHS slave unit 5 is registered in the public base station 3), the incoming call transferred to the public base station 3 is the PH.
Since the information is transmitted to the S slave unit 5 and called, the "slave unit incoming OK?" In step S55 becomes "Y". On the other hand, when incoming call rejection is not set in the public base station 3 and the private base station 1 is not detecting a slave, the incoming call is transferred to the public base station 3 (either of the determinations in steps S52 and S53). ("N" in the case where the incoming call is transferred to the public base station 3 in step S54), the PHS child device 5 cannot be called to the child device 5 because it is not within the service area of the public base station 3. Therefore, the determination in step S55 is "N". In such a case, the incoming call addressed to the corresponding PHS slave is transferred to the PHS answering center 110 in the switching network 100 (step S56). By doing so, the message message of the caller becomes P
It is recorded in the HS absence center 110. Further, when the incoming call rejection is not set in the public base station 3, the PHS slave unit 5 is detected by the own base station 1 and the determination in step S53 is “Y”.
In this case, the incoming call addressed to the PHS slave device 5 is transferred to the self-operating base station 1 (step S57), and the PHS is transmitted from the self-operating base station 1 to the PHS.
The calling of the slave unit 5 is performed.

[0031]

As described above, according to the present invention, when the private base station detects a PHS handset, it notifies the switching network and the switching network transmits the telephone number of the calling private base station. When the outgoing operation of the PHS slave is detected, if the own base station detects the PHS slave, the incoming call based on the outgoing operation is reported to the own base station, while the own base station detects the PHS slave. If not, the incoming call is notified to the public base station. Therefore, the PHS slave unit is used as a mobile terminal used through the public base station and a cordless mobile terminal used through the private base station. It can be used effectively as a machine. In addition, the private base station notifies the switching network that it is set to be away, and the switching network notifies the incoming call to the public base station when the private base station is set to leave when the switching network detects the calling operation. On the other hand, when the self-operating base station is not set to answer, the incoming call is notified to the self-operating base station, so that the PHS slave is similarly effectively used as a mobile terminal and a cordless slave, which are the original usage modes. it can. When the public base station detects the PHS handset, the public base station notifies the switching network of the location registration information.
When the location of the HS slave unit is registered, the incoming call is reported to the public base station, while when the location of the PHS slave unit is not registered in the public base station, the incoming call is reported to the self-operated base station. Similarly, the PHS slave can be effectively used as a mobile terminal and a cordless slave, which are the original usage forms.

Claims (3)

[Claims] 1. A self-contained base station, a public base station, a PHS slave unit wirelessly connectable to the self-contained base station and public base station, and a switching network accommodating the self-contained base station and public base station. In the PHS telephone system, the self-operating base station includes: a detecting unit that detects the PHS slave;
Notifying means for notifying the switching network that the PHS slave has been detected when the S slave has been detected, and notifying the switching network that the PHS slave has not been detected when the detecting means cannot detect the PHS slave. When the switching network detects any one of the outgoing operation of the telephone number of the self-managed base station and the telephone number of the PHS slave, if the notifying means notifies the detection of the PHS slave, the switching network performs the outgoing operation. On the basis of the PHS
P is provided with an incoming call notifying means for notifying the incoming call to the public base station when the detection of the handset is not notified.
HS phone system. 2. A self-contained base station, a public base station, a PHS slave unit wirelessly connectable to the self-contained base station and the public base station, and an exchange network accommodating the self-contained base station and the public base station. In the PHS telephone system, the self-operating base station includes: a detection unit that detects whether or not the self-attachment setting is performed; and a notification unit that notifies the switching network of the absence setting when the detection unit detects the absence setting. When the switching network detects one of the outgoing operation of the telephone number of the own base station and the telephone number of the PHS slave, the incoming call based on the outgoing operation is provided if the notifying unit notifies the absence setting. A PHS telephone system comprising: a call notification unit for notifying the public base station of the incoming call and notifying the absence setting by the notifying unit, but notifying the incoming call to the own base station. 3. A self-contained base station, a public base station, a PHS slave unit wirelessly connectable to the self-contained base station and the public base station, and a switching network accommodating the self-contained base station and the public base station. In the PHS telephone system, the self-operating base station has one of first detection means for detecting the PHS slave and second detection means for detecting whether or not itself is set to answer. When the first detecting means detects the PHS slave, the switching means notifies the switching network of the detection of the PHS slave, and the first detecting means
When the HS slave unit cannot be detected, the first notification unit and the second detection unit for notifying the switching network that the PHS slave unit has not been detected notify the switching network of the absence setting when the absence setting is detected by the second detection unit. The public base station detects the PHS slave, and notifies the switching network of location registration information indicating that the location of the PHS slave has been registered.
The switching network detects the outgoing operation of either the telephone number of the self-managed base station or the telephone number of the PHS slave unit, and the third notification unit notifies the location registration information. In such a case, while the third notification unit notifies the incoming call based on the calling operation to the public base station, when the third notification unit does not notify the location registration information, the third notification unit notifies the public base station of the incoming call. A PHS telephone system, characterized in that:
