Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a communication device such as a telephone, and more particularly, to a communication device capable of accommodating at least one slave unit.

[0002]

2. Description of the Related Art With the development of communication technology in recent years, public lines have become more intelligent, communication speed has been increased, and a line accommodating a plurality of lines has been proposed.

[0003] This is a digital line called, for example, ISDN.
In S64, two lines are accommodated using the subscriber line used in the current analog public line, and the data transmission speed is further improved to 64 kbps.

[0004] As PCs (personal computers) have become widespread in homes, the need for the simultaneous use of the two lines and the need for high-speed data communication have increased, and the ISDN lines have exploded.

[0005] Further, wireless communication technology has been improved, and systems using various wireless communications have been proposed. Among these wireless technologies, digital cordless telephones (PHS) with high sound quality, excellent confidentiality, and corresponding to high-speed data communication have been spotlighted.

In such a situation, a system has been proposed which integrates the device connected to the ISDN with the digital wireless communication system. It is connected to the ISDN and houses a digital wireless handset, and can be used as a normal cordless telephone. In this case, since two or more lines are accommodated, two lines can be used at the same time. By registering these two lines as different telephone numbers (dial-in) or distinguishing them by subaddress,
Not only can two lines be used at the same time, but also two independent lines can be used, and a system that further utilizes the above advantages of the digital wireless handset can be obtained.

Further, a device such as a printer can be built in or externally attached to the device, and high-speed wireless data communication can be performed with a data processing device connected to a slave unit, thereby enabling wireless printing and the like. There is a system to do.

[0008]

In such a system, if an incoming call to an outside line occurs during data communication between the slave units and a printer or the like, the slave unit used for data communication cannot receive an incoming call. Only the handset of the main unit (parent device) or another accommodated child device can receive an outside line. For example, when a slave unit or master unit other than during data communication is installed in a remote place, there is a disadvantage that it is necessary to go to that place and take an outside line.

In order to solve this drawback, there has been proposed a method of interrupting data communication in a slave unit during data communication and giving priority to an outside line call in the slave unit if there is an external incoming call and the call has priority. However, in this case, data communication is always interrupted. For example, in the case of ISDN, data communication is not performed even if a call is made without specifying a sub-address or dial-in (broadcasting), or if a terminal other than a slave unit that is performing data communication is specified by a sub-address or dial-in. There is a problem that the data communication is interrupted and the data communication throughput is reduced.

According to the present invention, when an incoming call is received while a slave unit is communicating, according to the type of incoming call and the communication mode of the slave unit,
An object is to enable optimal incoming call control.

[0011]

FIG. 3 is a diagram showing the configuration of the slave unit 101 in the above embodiment.

The slave unit 101 has a CP for controlling the slave unit 101.
U301 and memory 30 for storing data / program
2 and an operation panel 303 for inputting a telephone number and the like
A display device 304 for displaying a telephone number or the like, a baseband processing unit 306 similar to the baseband processing unit 207,
A wireless unit 307 similar to the wireless unit 208 is provided.

Further, the baseband processing unit 306 includes:
A microphone 308 and a speaker 309 are connected, and input and output of sound are performed with this. The external interface 305 connects the information processing device 103 such as an external personal computer.

In the slave unit 101, when a normal voice call is made, a voice signal from the microphone 308 is converted into a digital signal by the baseband processing unit 306, and the radio unit 30
7 to the wireless band, and as the wireless audio data, the master unit 1

For example, when data from the slave unit 101 of the data communication to the master unit 100 is print data,
If the print data is printed by the print processing unit 205 of the master device 100, a wireless print function becomes possible.

The configuration of the child device 102 is the same as that of the child device 101 described above.

Next, the outside line receiving function in the above embodiment will be described.

FIG. 4 is a flowchart showing the outside line receiving function in the above embodiment.

First, it is checked whether there is an incoming call from outside (S
1). This can be checked in the case of ISDN by checking whether a call setup signal has been received from the control channel (D channel). Here, if it is determined that there is an incoming call, the process proceeds to S2, and it is checked whether the incoming call is an individual incoming call.

In this method, it is possible to determine whether the incoming call is an individual incoming call by analyzing the called number included in the call setting and determining whether the incoming call number is specified by a dial-in number or a subaddress. . Here, when it is determined that the incoming call is not the individual incoming call, it is the simultaneous incoming call operation (S3) (this simultaneous incoming call operation will be described later). If it is determined that the incoming call is an individual incoming call, it is determined whether or not the designated terminal is a handset (S4). If not, the incoming call is made to the base unit 100 (S5).

After the incoming call operation at the base unit 100, S
8 and later. When it is determined that the child device has been designated (S4), the usage status of the designated child device is determined (S4).
6) If the designated slave unit is not used, an incoming call is made to the slave unit (S7). Whether or not the slave unit is in use can be determined using, for example, a flag for managing the used resources. After S5 and S7, a call signal is sent out to the line (S8), and it is determined whether or not a call is received by the designated master unit 100 or slave unit.
This incoming call is determined by off-hook of the parent device 100 or the child device (S9). When this off-hook is detected, a response signal is sent to the line 105 (S10), and a call to an outside line is started at the designated master unit 100 or slave unit (S11).

Next, when it is determined that the designated slave is in use (S6), it is determined whether or not the designated slave is performing data communication (S20). This determination can be made by using the operation mode flag of the operation resource or the like in the same manner as the above-mentioned determination during use of the slave unit. When it is determined that the designated slave unit is in non-data communication (ie, during a call) (S20), a busy signal is transmitted to the line (S21), and the line is disconnected (S2).
2). Here, the line is disconnected when busy, but instead of disconnecting when busy, a busy call may be made to the slave unit by, for example, a call waiting function.

When it is determined that the designated slave unit is performing data communication (S20), the data communication is interrupted (S23) (this interruption processing means will be described later).

Then, a call signal is transmitted to the line (S
24), the off-hook of the slave unit is determined (S25). When the off-hook is confirmed, a response signal is transmitted to the line (S2).
6), a call with the slave unit is started (S27).

Next, it is determined that the communication with the slave unit has ended (S2).
8) At the end of the call, the line is disconnected (S29). Here, the termination of the call is determined, for example, in the case of disconnection from the slave unit, by detecting the on-hook of the slave unit, and, when disconnecting from the other party, by receiving a disconnection signal on the line. The line disconnection is performed by a normal ISDN disconnection unit.

Next, the suspended data communication between the parent device and the child device is resumed (S30). About this resumption means,
It will be described later.

[Second Embodiment] Next, a simultaneous incoming call according to a second embodiment of the present invention will be described.

The configuration of the second embodiment is the same as the configuration shown in FIGS.

In the second embodiment, the CPU 201
This is an example of a general incoming call detecting means for detecting that the type of incoming call on the external line is a general incoming call, and a data communication mode detecting means for detecting that the communication mode of the slave unit being used is the data communication mode. It is an example.

Further, when the simultaneous incoming call detecting means detects that a simultaneous incoming call has been received from the external line when the external incoming call is received from the external line, the CPU 201 determines that only one handset is in use, and If the communication mode of the slave unit being used is the data communication mode, the data communication with the slave unit is interrupted, the simultaneous radio call is received by the slave unit, and the slave unit receives an outside line. It is an example of a data communication interruption unit for making a call.

Further, the CPU 201 is an example of external line communication end detecting means for detecting the end of the external line communication by the slave unit. When the external line communication end detecting means detects the end of the external line communication, the data for restarting the data communication is provided. It is an example of communication restart means.

FIG. 5 is a flowchart showing the operation of the second embodiment of the present invention.

FIG. 5 is a continuation of step S5 in the flowchart shown in FIG. That is, the operation after the simultaneous incoming call is already determined.

First, it is determined whether or not there is an in-use slave unit using the same resource management flag or the like as described above (S31). (At this time, if the base unit 100 is also unused, the incoming call is also made to the base unit 100) (S32), and the process proceeds to S37 and thereafter.

Next, it is determined whether or not another unused handset exists (S33). If there is an unused handset, the process proceeds to S33.
34, and if the base unit 100 is also unused,
, And a call is made to an unused slave unit at the same time, and the process proceeds to S37 and thereafter.

Next, it is determined whether or not the child device in use is performing data communication (S35). Since there is no unused child device before S35, only the child device that is being used is in data communication.

Here, it is determined that the slave unit is in a call,
If the base unit 100 is not used, the incoming call is made to the base unit 100 (S36). Here, if the base unit 100 is also in use, processing such as returning a busy to the line and disconnecting the line is also necessary. However, the description is omitted here, and the case where the base unit 100 is unused is used. Only the following will be described.

Next, a call signal is transmitted to the line (S3).
7), when an incoming call is detected by on-hook detection or the like in the parent device 100 or the child device (S38), a response signal is transmitted to the line (S39), and a call is started in the parent device 100 or the child device. Is performed (S40).

Next, when it is determined that the only slave unit is performing data communication (S35), the data communication is interrupted by means described later (S50), and a calling signal is sent out to the line (S35).
51) When the off-hook of the slave unit is confirmed (S52),
A response signal is transmitted to the line (S53), and an external call is started by the slave unit (S54).

Then, the end of the call is determined by the on-hook detection of the slave unit or the disconnection signal detection means from the outside line partner (S).
55) When the end of the call is detected, the line is disconnected by ordinary means.

Next, the data communication between the master unit and the slave unit is restarted by the data communication restart means described later.

[Third Embodiment] Next, the data communication suspending means and the resuming means which are not described in the above embodiment will be described.

As these means, two means can be considered.

FIG. 6 is a sequence diagram showing interruption / resumption of data communication in the third embodiment of the present invention.

The first of the above two means is:
Without disconnecting the communication channel, suspend only data communication,
FIG. 6 shows a sequence diagram in this case.

In FIG. 6, when a call is received from external line 105 during data communication between master unit 100 and the slave unit, a call setting signal is received from line 105 to master unit 100. Upon receiving this, master device 100 performs the process of the flowchart shown in FIG. 6 and executes a process of interrupting data communication.

More specifically, a data communication interruption request signal is sent to the child device, the reception of a data communication interruption completion signal from the child device is waited, and when the data communication interruption completion signal is received, the master device 100 A call setting signal is transmitted to the slave unit. At this time, the communication channel is not disconnected, and the child device
When the call setting signal is received, a call setting acceptance / call signal is transmitted to the line through the base unit 100 to notify the other party that the handset or the terminal including the handset is calling.

Here, when the slave unit receives an incoming call off-hook or the like, the slave unit sends a response signal to the line 105 via the base unit 100 and receives a response confirmation from the line 105 in the same manner as described above. Then, a call between the slave unit and the outside line partner is started.

Next, when the call is terminated, for example, in the case of disconnection from the slave unit, a disconnection signal is sent from the slave unit to master unit 100.
A release signal is transmitted to the line 105 and received through the line 105-base unit 100, the completion of release to the base unit 100-line 105 is completed, and the external line 105 is disconnected. Then, master device 100 issues a data communication restart request signal to the slave device, and upon receiving a data communication restart completion signal from the slave device, data communication between the master device and the slave device is restarted.

Next, a description will be given of the second data communication interruption / resumption processing in the third embodiment.

FIG. 7 shows a second embodiment according to the third embodiment of the present invention.
FIG. 10 is a sequence diagram showing a second data communication interruption / resumption.

The second of the above two means is:
This is a means for making a call after disconnecting the communication channel itself and resuming communication channel establishment when resuming. FIG. 7 shows a sequence diagram in this case.

Similarly to the above, if there is an incoming call from the external line 105 during data communication between the master unit and the slave unit,
5, a call setup signal is received. Here, master device 100 transmits a wireless disconnection request to the slave device to interrupt data communication, and upon receiving a wireless disconnection completion signal from the slave device, the wireless channel used for data communication is disconnected. .

Next, the slave unit issues a link channel establishment request to master unit 10 in order to reset the master unit 100 and the wireless channel.
By transmitting a link channel assignment signal from the base unit 100 to 0, a wireless channel with the base unit 100 is re-established.

Here, base unit 100 issues a call setting signal to the slave unit to notify the incoming call, and thereafter, a call between the slave unit and the external line is started in the same procedure as in FIG. .

Next, when the communication with the slave unit is completed, the slave unit issues a disconnection signal to the line 105 in the same manner as described above.
Upon receiving the release signal from the line 105, an open completion signal is sent to the line 105, and the external line 105 is disconnected.

Here, base unit 100 issues a wireless disconnection request to the slave unit, and upon receiving a wireless disconnection completion signal from the slave unit, temporarily disconnects the wireless channel used for external line 105. Next, the slave unit issues a link channel establishment request to master unit 100 and receives a link channel assignment signal from master unit 100, whereby a wireless channel is formed again. Further, base unit 100 issues a call setting signal to the slave unit to make an extension call for data communication, and thereafter, after receiving a call setting reception, a call signal, and a response signal, transmits a response confirmation signal. After transmission, a data channel is formed and data communication is resumed.

[0074]

As described above, according to the present invention, it is possible to perform optimal incoming call control according to the type of incoming call and the communication mode of the slave unit during communication. For example, in the case of an individual incoming call specified by the slave unit in response to an incoming call during data communication in the slave unit, the data communication is interrupted and the incoming call can be received by the slave unit, so that an external call can be reliably received. In addition, at the time of an incoming call to a device other than the child device during data communication, the data communication is not interrupted, and the data communication throughput is not reduced.

For example, in the case of a simultaneous incoming call,
If there is only one unit and the slave unit is in data communication, data communication is interrupted and incoming calls can be received at the slave unit, so even if the master unit is placed at a remote location, There is an effect that an incoming call can be received at the child device without moving.
