2. Description of the Related Art Today, telephone lines are widely used not only for voice communication but also for data communication such as the Internet. As one method of effectively using a telephone, a parent-child telephone using a parent device and a plurality of child devices is known. Among the parent and child telephones, cordless telephones for wirelessly communicating between the parent and child are widely used because the child is very easy to use. JP-A-5-103056, JP-A-6-121028, and JP-A-10-1028
JP-A-23547 discloses a prior art related to a cordless telephone.

In a cordless telephone, a telephone communication system is composed of a main unit as a master unit connected to a telephone line and a slave unit that can use the telephone line by registering with the main unit and making a wireless connection. A plurality of slave units can be registered in the master unit. If one slave unit is using the telephone line, the call cannot be used even if a call is made from another slave unit. Can be started.

[0004] Japanese Patent Application Laid-Open Nos.
Japanese Patent Application Laid-Open No. 121028 discloses that if a telephone line is already in use at the time of calling a handset, the base phone stores the destination telephone number and reserves calling, and when the use of the telephone line is completed, the handset is notified of it. There is disclosed a technology for notifying a user and automatically dialing a stored destination. Also, Japanese Patent Application Laid-Open No. 5-37
Japanese Unexamined Patent Publication No. 649 discloses a technique in which, when a plurality of extension telephones make a call to an outside line, a reservation is made when there is no available outside line, and after the outside line becomes available, the extension telephone is called by voice.

FIG. 5 shows a sequence for making a call reservation in a parent-child telephone system including a parent device and two child devices A and B. Initially, it is assumed that the slave A is communicating with an external telephone line via the master. When the slave unit B attempts to make a call to an external telephone line, the master unit rejects the call to the slave unit B. At this time, the master unit sets a reservation for slave unit B and stores the destination. When the communication with the child device A ends, the parent device starts notification to the child device B. First, slave unit B
When the slave unit B responds, a call is made to the destination via the telephone line, and communication between the destination and the slave unit B is performed.

Japanese Patent Laid-Open Publication No. Hei 10-23547 discloses a cordless telephone that uses a one-slot wireless line between a master unit and a plurality of slave units. Discloses a technique for receiving a control channel sent from a base unit and automatically making a call when transmission becomes possible.

[0007]

In a cordless telephone or the like, if the telephone line is already in use when the slave unit tries to make a call, or if the wireless slot is already in use, the call is made after a free space is created. You need to get started. For this reason, it is necessary to wait for the termination of a call or the like via a telephone line by another slave unit until a vacant space is created, and the telephone line cannot be used efficiently. JP-A-10-
In a cordless telephone as disclosed in Japanese Patent No. 23547, a calling operation is automatically performed when communication becomes possible, so that the user does not need to wait until communication becomes possible. However, if the communication needs to be performed by human intervention, the call must be made automatically and the human intervention does not need to be performed, but the communication must ultimately be performed by human intervention. However, communication is not always possible when it is convenient.

[0008] Japanese Patent Application Laid-Open Nos.
In a cordless telephone disclosed in Japanese Patent Application Laid-Open No. 121028, when communication becomes possible as shown in FIG. 5, the base unit automatically sends a call to the other party, and the technology for connecting the slave unit to the other party also makes a call. The timing of connection with the other party is not always convenient for the user of the slave unit. If the user of the slave unit is connected to the calling party at a timing when the user cannot intervene in the call, the connection may be wasted in the case of communication that requires human intervention.

[0009] In the case where transmission is possible automatically from the slave unit to the destination of the call, for example, as in the case of e-mail, communication can be performed automatically when the terminal is connected to the destination of the call. However, there is a case where the time elapses from the time of the first call to the time when the call can be made, and the contents of the previously created e-mail are inappropriate due to changes in circumstances during this time. obtain.

[0010] It is an object of the present invention to provide a method of making a call reservation of a wireless parent-child telephone, and a parent device, a child device, and an adapter, which can easily adjust the timing for retransmission when communication becomes possible. It is.

FIG. 4 shows an operation sequence when a radio-type parent-child telephone system is formed using the master unit of FIG. 1, the slave unit of FIG. 2, and the adapter of FIG. Slave units are A and B
It is assumed that the two units are used and an adapter is connected to the slave unit B. The signal names used for the description in this sequence are used for expressing their functions. However, even if other names have the same meaning, the same operation as in the present embodiment is performed. Can be done.
In other words, the signals operated between the master unit, the slave unit A, and the slave unit B are signals defined in RCR STD-28 which is a PHS standard. Will be explained. In addition, the signals transmitted and received between the slave unit B and the adapter will be described using names whose meanings are easy to understand. The actual content of the signal is defined in each system. Here, the description will be made on the assumption that the adapter has an electronic mail transmission / reception function and the electronic mail is transmitted using the function.

(1) First, it is assumed that one slave unit A is connected to a telephone line via a relay of a master unit and is in a communication state.

(2) Here, when the user of the adapter performs an e-mail transmission operation, an "outgoing call" is transmitted from the adapter to the slave unit B, and the slave unit B receiving the transmission transmits the "call" to the master unit. Send "outgoing request". This "outgoing request"
In the S standard, this is called a “link channel establishment request”.

(3) The master unit that has received the "call request" from the slave unit B recognizes that the slave unit A is using the telephone line by the recognition unit 2, and cannot send a call to the slave unit B. In order to notify that, the status notifying unit 3 transmits “Call rejection”. This “transmission rejection” is called “link channel assignment rejection” in the PHS standard. "Call rejection" has an area for notifying the reason for rejecting the call. In this area, the user is notified that the telephone line or the wireless slot that can be controlled by the base unit cannot be used, and that it becomes available when it becomes available. A code indicating the information of the effect is set. At the same time, the state notifying unit 3 stores that the reservation for the slave unit B has been made. Slave unit B that has received "Call rejection" from the master unit
Stores the reason information of the transmission rejection contained therein in the information transfer unit 6, and transmits "transmission failure" to the adapter.

(4) The adapter which has received the "call failure" from the slave B sends a "reason inquiry" to the slave B in order to know the reason for the call failure.

(5) The slave unit B that has received the "reason inquiry" from the adapter transmits the reason information of the transmission rejection stored in the information transfer unit 6 to the adapter as "reason notification". The adapter that has received the "reason notification" from the slave unit B analyzes the reason with the recognition unit 10, and determines that the reason for the outgoing failure is that the telephone line or the wireless slot controlled by the master unit cannot be used, and that the adapter can be further used. Then, it is understood that the notification is made, and it is possible to confirm that the transmission is already reserved by the master unit. By this confirmation, the transmission is stopped. The user can be notified that the transmission is already reserved via the user interface unit 11 of the adapter.

(6) Thereafter, when the communication of the slave unit A is completed, the master unit starts an operation for notifying the slave unit B of the availability of the telephone line and the availability of the wireless slot controlled by the master unit. I do.

(7) The parent machine automatically transmits an "incoming call" to the slave machine B for which a call is reserved. This “incoming call” is called “incoming call” in the PHS standard.

(8) A sequence for establishing a wireless link is advanced between the master unit and the slave unit B, and the master unit transmits “call setting” to the slave unit B. This "call setup"
It is also called "call setup" in the HS standard. "Call Setup"
Is provided with a notification information area, in which a code indicating information indicating that a telephone line or a wireless slot controlled by the master unit has become available is set. As the notification information area, calling sub address information can be used. The slave unit B that has received the “call setting” from the master unit transmits the notification information included therein to the adapter together with the incoming call information. Upon receiving the incoming call information and the accompanying notification information from the slave unit B, the adapter analyzes the reason with the recognition unit 10 and notifies that the telephone line or the wireless slot controlled by the master unit has become available. The user can understand that the telephone line has become available via the master unit. With this confirmation, a state is established in which transmission is possible.

(9) The adapter that has confirmed that the telephone line has become available automatically transmits a call, so that an "outgoing signal" is transmitted to the handset B, and the handset B Sends a “call request” to the parent device. This “transmission request” is called a “link channel establishment request” in the PHS standard.

(10) The master unit that has received the “call request” from the slave unit B transmits “call permission” to the slave unit B, and thereafter communicates with the slave unit B. "Call permission" is P
In the HS standard, it is called "link channel assignment". At this point, the fact that communication has been established is notified from the slave unit B to the adapter using a “communication notification”, and the adapter that has received the “communication notification” can perform the transmission processing of the e-mail to be transmitted first. It becomes possible.

If it is not acceptable to send an e-mail while waiting for transmission to be possible, the adapter sends the e-mail as it is, and for some reason, transmission of the e-mail is hindered. Then, the user can perform an operation so as not to transmit the e-mail. When transmitting an e-mail, the master unit calls a transmission destination via a telephone line and relays the transmission of the e-mail. When the e-mail is not transmitted, no call is made to the other party via the telephone line, so that a useless call can be avoided.

According to the operation of the present embodiment as described above,
When a call was made from the slave unit, if the telephone line or the wireless slot available for the master unit could not be used, the call was reserved on the master unit and the call was reserved for the slave unit. In this case, the communication with the reserved slave unit can be performed by using the incoming call operation when it becomes available. By notifying the slave unit that it has become usable, it becomes possible to make a call from the adapter on the slave unit in the same process as a normal call.

For example, as described above, if the adapter has an e-mail transmission / reception function, the user connects to the telephone line via the parent device using the slave unit and performs an operation to transmit the e-mail. However, if the other handset is using the telephone line, the user will do nothing
When another child device finishes using it, it can automatically connect to the telephone line via the parent device and send an e-mail. The master unit only notifies the slave unit that has requested the transmission of the e-mail from the adapter when communication becomes possible, so that the user of the adapter cannot send the e-mail until the user of the adapter becomes communicable. In the case of canceling the communication, the transmission of the e-mail may be canceled simply by operating the adapter. Even if there is a notification from the master unit that communication has become possible, the transmission of the electronic mail becomes possible, and the adapter does not need to transmit the electronic mail. The parent machine is
Since the connection to the other party is made via the telephone line after waiting for the call from the slave unit, if no e-mail is sent from the adapter via the slave unit, connect to the other party via the telephone line. In other words, it is possible to avoid unnecessary connection to the telephone line.

In the embodiment described above, an example is described in which an adapter having an e-mail transmission function is connected to the slave unit to make a reservation. However, the user can connect the slave unit without connecting the adapter to the slave unit. Even if the parent device makes a reservation for outgoing calls of the slave device, the master device can communicate with the slave device via the telephone line without connecting to the called party. If the notification is made, useless connection of the telephone line can be avoided when the handset does not need to make a call.

[0043]

As described above, according to the present invention, a call is requested from the slave to the master, and if the communication is not possible, the reason is notified from the master to the slave, and the slave is notified of the reason. Recognize and wait. When communication becomes possible, an incoming call is made from the parent device to the child device, a notification that the communication is possible is made, and the child device can make a call, so that the user of the child device is convenient. The transmission can be performed again at the timing.

According to the present invention, when a call is made via the adapter connected to the slave unit, if communication is not possible, the reason that the master unit notifies the slave unit is transferred to the adapter, and communication is performed. The notification from the master unit to the slave unit when
Since the data is transferred from the slave unit to the adapter, communication using the adapter can be performed at a convenient timing.

According to the present invention, an electronic mail can be transmitted at a convenient timing.

Further, according to the present invention, when it is impossible to make a call via the telephone line in response to a request from the slave, the reason is notified to the slave, so that the slave is made to wait until the reason is resolved. Can be. The child device is stored, and when communication becomes possible, the fact is notified to the child device. Therefore, if a call is made again from the child device, it is possible to easily connect to the destination via the telephone line.

Further, according to the present invention, when the adapter connected to the slave unit attempts to make a call, if the communication is not possible, the communication is performed according to the information notified from the master unit. Waiting until it becomes possible and receiving a notification from the master unit that communication is possible, the reason is transferred to the adapter, so that the adapter can be operated in accordance with the use state of the master unit. When the master unit notifies the slave unit that communication is possible, the contents of the notification are transferred to the adapter, so that the adapter makes a call again and the master unit sends information about the user to the telephone line. Can be notified. This allows the user of the adapter to make the call again at a convenient timing.

Further, according to the present invention, a call is transmitted from the adapter via the slave unit, and when communication cannot be performed for the call, the use state of the master unit is determined based on information notified from the master unit to the slave unit. Can be recognized. Communication becomes possible, and when a call is received from the master unit to the slave unit, it is recognized that the adapter can also communicate via the slave unit, and the user of the adapter must perform a calling operation at a convenient timing. Can be.
