Description

  The present invention relates to a technology for a parent-child telephone system using a main device, and more particularly to a technology for setting a parent-child relationship.

  Patent Document 1 describes a base unit and a handset of a cordless telephone that does not impair a memory life and does not allow a valid handset and an unauthorized handset to coexist. In this patent document 1, when detecting the charging of the child device, the parent device notifies the child device of an ID common to the parent and child. If there is a response from the slave unit, a wireless link is established for the slave unit. If there is no response, a new ID is generated and notified to the slave unit. On the other hand, the slave unit checks whether or not the ID notified from the master unit coincides with the ID of its own unit when charging from the master unit starts. If they match, this base unit is requested to establish a radio link. If they do not match, the host device waits for a new ID and updates its own device ID to this new ID. Thereafter, the base unit is requested to establish a radio link.

  Here, in the fields 181 and 182, a telephone number and address information of the wired terminal 21 are registered in advance. In the field 183, the address information of the wireless terminal 22 is registered only when there is a wireless terminal 22 that has a parent-child relationship with the wired terminal 21. When a parent-child relationship is established between the wired terminal 21 and the wireless terminal 22, the wired terminal 21 becomes a parent device, and the wireless terminal 22 becomes a child device.

  And the main control part 19 controls each part 11-18 of the independent apparatus 1 centralizedly.

  Specifically, when the main control unit 19 receives call data from the external line network 5 via the external line IF unit 11, the communication control unit 13, the router unit 15, and the GW unit 14, the main control unit 19 refers to the parent-child information storage unit 18. Then, the address information of the wired terminal 21 to which the call data receiving number is assigned is acquired. Then, the call data and the acquired address information are passed to the call control unit 16. In response to this, the call control unit 16 performs incoming processing in cooperation with the main control unit 19, and establishes a voice path (call path) between the wired terminal 21 specified by the address information and the call data source. Set.

  When the main control unit 19 receives call data from the wired terminal 21 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14, it passes this call data to the call control unit 16. . In response to this, the call control unit 16 performs a calling process in cooperation with the main control unit 19 and sets a voice path between the wired terminal 21 and the destination of the call data.

  Further, the main control unit 19 performs a parent-child relationship setting process for the wired terminal 21 and the wireless terminal 22. FIG. 4 is a flowchart for explaining the parent-child relationship setting process of the main device 1.

  When receiving a parent-child setting request from the wired terminal 21 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14 (YES in S101), the main control unit 19 receives the current time from the clock unit 17. Is stored in a memory or the like (not shown) in association with the address information of the wired terminal 21 as the arrival time of the parent-child setting request (S102).

  On the other hand, when the main control unit 19 receives a parent-child setting request from the wireless terminal 22 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14 (YES in S103), the main control unit 19 The current time is acquired and stored in a memory (not shown) or the like as the arrival time of the parent-child setting request in association with the address information of the wireless terminal 22 (S104).

  When the main control unit 19 receives the parent-child setting request from both the wired terminal 21 and the wireless terminal 22 (YES in S105), the main control unit 19 refers to a memory or the like (not shown) and For each, it is checked whether there is only one stored arrival time (S106).

  When there are a plurality of arrival times stored in a memory (not shown) for at least one of the wired terminal 21 and the wireless terminal 22 (NO in S106), the arrival times are registered in the memory (not shown). A retry request for prompting the wired terminal 21 to retransmit the parent-child setting request is transmitted from the extension IF unit 12 via the GW unit 14, the router unit 15, and the communication control unit 13 (S107). Here, when the retry request is transmitted to the plurality of wired terminals 21, each wired terminal 21 is transmitted such that the retry request is transmitted to each wired terminal 21 at an interval from a predetermined time of S 108 described later. The transmission timing of the retry request for is shifted. Thereafter, the arrival time information stored in a memory (not shown) is cleared and the process returns to the start.

  On the other hand, when there is only one arrival time stored in a memory (not shown) for each of the wired terminal 21 and the wireless terminal 22 (YES in S106), the arrival time of the wired terminal 21 and the wireless terminal 21 A time difference from the arrival time of the terminal 22 is obtained, and it is checked whether this time difference is within a predetermined time (for example, 2 seconds) (S108). If not within the predetermined time (NO in S108), the main control unit 19 sends a retry request for prompting the wired terminal 21 to retransmit the parent-child setting request, the GW unit 14, the router unit 15, and the communication control unit. 13 from the extension IF unit 12 (S109). Thereafter, the arrival time information stored in a memory (not shown) is cleared and the process returns to the start. On the other hand, if it is within the predetermined time (YES in S108), the process proceeds to S110.

  In S110, the main control unit 19 searches for the record 180 from the parent-child information storage unit 18 using the address information of the wired terminal 21 whose arrival time is stored in a memory (not shown) as a key. Then, it is checked whether or not the address information of the wireless terminal 22 is registered in the field 183 of the searched record 180.

  When not registered, that is, when the parent-child relationship is not set for the wired terminal 21 whose arrival time is stored in a memory (not shown) or the like (NO in S110), the main control unit 19 uses the parent-child information storage unit. 18, the record 180 in which the address information of the wireless terminal 22 whose arrival time is stored in a memory or the like not shown is registered in the field 183. If such a record 180 can be searched, the address information is deleted from the field 183 of the record 180. Further, the main control unit 19 registers the address information of the wireless terminal 22 whose arrival time is stored in a memory or the like (not shown) in the field 183 of the record 180 searched in S110. Then, the main control unit 19 transmits the slave unit information including the address information registered in the field 183 of the record 180 to the wired terminal 21 in which the address information is registered in the field 182 of the record 180 searched in S110. At the same time, the base unit information including the address information registered in the field 182 of the record 180 is transmitted to the wireless terminal 22 in which the address information is registered in the field 183 of the record 180 (S111). Thereafter, the arrival time information stored in a memory (not shown) is cleared and the process returns to the start.

  In S110, when the address information of the wireless terminal 22 is registered in the field 183 of the searched record 180, that is, the parent-child relationship has already been set for the wired terminal 21 whose arrival time is stored in a memory or the like (not shown). In some cases (YES in S110), it is determined whether the combination of the wired terminal 21 and the wireless terminal 22 whose arrival times are stored in a memory (not shown) or the like matches, and the number of appearances in the case of matching is determined. Increment by one. Then, it is checked whether or not the number of appearances has reached a predetermined value (for example, 3 times) or more (S112).

  In S112, when the number of appearances is equal to or greater than the predetermined value (YES in S112), the main control unit 19 stores the arrival time from the parent-child information storage unit 18 in a memory (not shown) or the like. The record 180 whose address information is registered in the field 183 is searched. If such a record 180 can be searched, the address information is deleted from the field 183 of the record 180. Further, the main control unit 19 uses the address information of the wireless terminal 22 registered in the field 183 of the record 180 searched in S110 as the address information of the wireless terminal 22 whose arrival time is stored in a memory (not shown). Update to Thereby, even in a terminal whose parent-child relationship does not match, the parent-child relationship can be automatically set by placing for a certain period of time. Then, the main control unit 19 transmits the slave unit information including the address information registered in the field 183 of the record 180 to the wired terminal 21 in which the address information is registered in the field 182 of the record 180 searched in S110. At the same time, the base unit information including the address information registered in the field 182 of the record 180 is transmitted to the wireless terminal 22 in which the address information is registered in the field 183 of the record 180 (S114). Thereafter, the arrival time information stored in a memory (not shown) is cleared and the process returns to the start.

  On the other hand, in S112, when the number of appearances is less than the predetermined value (NO in S112), the main control unit 19 applies to the wired terminal 21 and the wireless terminal 22 whose arrival times are stored in a memory (not shown) or the like. Then, an already-set notification for notifying that the parent-child relationship has been set is transmitted from the extension IF unit 12 via the GW unit 14, the router unit 15, and the communication control unit 13 (S113). Thereafter, the arrival time information stored in a memory (not shown) is cleared, and the process returns to the start.

  Then, when receiving the parent-child setting request from the plurality of wired terminals 21 and the plurality of wireless terminals 22 within a predetermined time, the main device 1 determines that the parent-child setting request has not been established (S606). Then, the main device 1 transmits a retry request for prompting retransmission of the parent-child setting request to each wired terminal 21 at least at the predetermined time interval (S607).

  Upon receiving the retry request, each wired terminal 21 outputs a signal to the wireless terminal 22 placed on the own terminal 21 (S608), and transmits a parent-child setting request to the main device 1 (S609).

Here, since the parent-child relationship of the wired terminal 21 has been set, it is determined that the parent-child setting request for both the terminals 21, 22 has not been established (S706). Then, the main apparatus 1 transmits to the both terminals 21 and 22 an already set notification indicating that the parent-child relationship has been set (S707, S708). In response to this, both terminals 21 and 22 perform a preset display indicating that the parent-child relationship has been set (S709, S710).

  The embodiment of the present invention has been described above.

  In the present embodiment, it is only necessary that the wireless terminal 22 can detect the signal output from the wired terminal 21 when setting the parent-child relationship. Therefore, according to the present embodiment, it is possible to set and manage a parent-child relationship without providing a special interface for transmitting and receiving an ID between the wired terminal 21 and the wireless terminal 22 such as serial communication.

  In the present embodiment, when the main device 1 receives a parent-child setting request from a plurality of wired terminals 21 and a plurality of wireless terminals 22 within a predetermined time, each of the plurality of wired terminals 21 Send retry requests at different times. When the wired terminal 21 receives a retry request from the main device 1, it transmits a parent-child setting request to the main device 1, and sends a signal to the wireless terminal 22 placed on the own terminal 21, so that the wireless terminal 22 Then, a parent / child setting request is transmitted to the main apparatus 1. Thus, in the present embodiment, even when a parent-child setting request is transmitted from a plurality of wired terminals 21 and a plurality of wireless terminals 22 within a predetermined time, the parent-child relationship of each wired terminal 21 is set. can do.

  In the present embodiment, when the main apparatus 1 receives a parent-child setting request from one wired terminal 21 and one wireless terminal 22 within a predetermined time, the parent-child relationship of the wired terminal 21 is already set. In this case, an already set notification is transmitted to the wired terminal 21. When the wired terminal 21 receives the already-set notification from the main device 1, the wired terminal 21 transmits a parent-child setting request to the main device 1, and sends a signal to the wireless terminal 22 placed on the own terminal 21. 22 causes the main apparatus 1 to transmit a parent-child setting request. When the situation of receiving the parent-child setting request within a predetermined time is repeated a predetermined number of times for the same combination of the wired terminal 21 and the wireless terminal 22, the main device 1 selects a child device having a parent-child relationship with the wired terminal 21. Update to this wireless terminal 22. By doing in this way, in this Embodiment, the parent-child relationship of this wired terminal 21 is continued by mounting the wireless terminal 22 which is not in the parent-child relationship with this wired terminal 21 in the wired terminal 21 in which the parent-child relationship has been set. Can be updated easily.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary. For example, each configuration of the main device 1, the wired terminal 21, the wireless terminal 22, and the wireless AP 3 is implemented by an integrated logic IC such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). Alternatively, it may be executed by software by a computer such as a DSP (Digital Signal Processor) or a PC (Personal Computer).

  Further, in the present embodiment, the case where the mounting state of the wireless terminal 22 is detected by a sensor provided in the wireless terminal IF unit 2108 of the wired terminal 21 has been described as an example. However, the present invention is not limited to this. For example, the mounting state of the wireless terminal 22 may be detected by monitoring the charging state of the wireless terminal 22 with the power supply control unit 2109 of the wired terminal 21.

  Further, in the present embodiment, a cue for sending a parent-child setting request is output from the cue output unit provided in the wireless terminal IF unit 2108 of the wired terminal 21, and this is provided in the wired terminal IF unit 2208 of the wireless terminal 22. The case where the signal is detected by the signal detection unit has been described as an example. However, the present invention is not limited to this. For example, by changing the power supplied to the wireless terminal 22 by the power supply control unit 2109 of the wired terminal 21 and detecting this by the power supply control unit 2209 of the wireless terminal 22, a signal for transmitting a parent-child setting request is output and detected. It may be.

  FIG. 14 is a diagram for explaining a modification of the wireless terminal IF unit 2108 and the power supply control unit 2109 of the wired terminal 21 and the wired terminal IF unit 2208 and the power supply control unit 2209 of the wireless terminal 22.

  As illustrated, in the wired terminal 21, the wireless terminal IF unit 2108 has power supply terminals 21082 and 21083 for supplying power to the wireless terminal 22. In addition, the power control unit 2109 measures a power supply 21091 that supplies power to the power supply terminals 21082 and 21083, a resistor 21095 inserted in the power supply line of the power supply 21091, and a current value flowing through the power supply line of the power supply 21091. It has a current meter 21093, a voltage meter 21094 that measures the voltage value between the power supply terminals 21082 and 21083, and a power supply controller 21092 that adjusts the power supplied to the power supply 21091.

  In the wireless terminal 22, the wired terminal IF unit 2208 includes power input terminals 22082 and 22083 that are connected to the power supply terminals 21082 and 21803 of the wired terminal 21 and input power from the wired terminal 21. The power control unit 2209 includes a voltage meter 22092 that measures a voltage value between the power input terminals 22082 and 22083, a battery 22091 that stores power input to the power input terminals 22082 and 22083, a power input terminal 22082, and a battery. And a diode 22093 inserted between 22091.

  In the configuration as described above, the power supply controller 21092 controls the supply power of the power supply 21091 based on the measured values of the current meter 21093 and the voltage meter 21094, and determines the mounting state of the wireless terminal 22 based on these measured values. To detect. When the current value of the power supply line is equal to or less than a predetermined value, it is considered that the power supply terminals 21082 and 21083 are open. Further, when the voltage value between the power supply terminals 21082 and 21083 is equal to or lower than a predetermined value, it is considered that some abnormality has occurred in the slave unit 22 and the power input terminals 22082 and 22083 of the slave unit 22 are short-circuited. In such a case, it is determined that the placement state is “non-placement”. Then, when the current value of the power supply line is within a predetermined range and the voltage value between the power supply terminals 21082 and 21083 is within the predetermined range, it is determined that the mounting state is “mounted”.

  Alternatively, the voltage value applied to the resistor 21095 is calculated using the output voltage of the power supply 21091 and the measured value of the voltage meter 21094, and the measured value of the voltage meter 22092 of the wireless terminal 22 is acquired via a communication terminal (not shown). To do. And a mounting state is detected by comparing both. For example, the resistance value of the resistor 21095 is set so as to be larger than the resistance value between the power input terminals 22082 and 22083 of the wireless terminal 22, and a voltage difference corresponding to the difference between the two resistance values is applied to the resistor 21095. When it occurs between the voltage value and the measured value of the voltage meter 22092, it is determined that the placement state is “placement”. In other cases, it is determined that the placement state is “non-placement”.

  In this embodiment, it is assumed that the placement state is detected on the wired terminal 21 side, but the placement state is detected on the wireless terminal 22 side and this is notified to the wired terminal 21 via the wireless network. You may make it do.

  In the configuration shown in FIG. 14, the power controller 21092 of the wired terminal 21 outputs a parent-child setting request signal by changing the power supplied to the wireless terminal 22 in accordance with an instruction from the main control unit 2111. For example, the signal applied to the parent / child setting request is output to the wireless terminal 22 by instantaneously interrupting the voltage applied between the power supply terminals 21082 and 21083 for a predetermined time. Then, by detecting this instantaneous interruption with the voltage meter 22092 of the wireless terminal 22, a signal of the parent-child setting request output from the wired terminal 21 is detected. As shown in FIG. 14, by connecting the voltage meter 22092 to the anode side of the diode 22093, even when the battery 22091 is attached to the wireless terminal 22, the change in the power supplied by the wired terminal 21 is detected by the voltage meter 2209. It becomes possible to detect.

  By doing so, it is possible to transmit a parent-child setting request signal from the wired terminal 21 to the wireless terminal 22 using a mechanism for charging the battery 22091 of the wireless terminal 22 placed on the wired terminal 21. Thus, the cost of the parent / child phone system can be further reduced.

Retry request is sent at the timing. However, the present invention is not limited to this. When the main device 1 receives a parent-child setting request from the plurality of wired terminals 21 and the plurality of wireless terminals 22 within a predetermined time, the main device 1 sends the plurality of wired terminals 21 to the own device 1 at different timings. Any device capable of transmitting a retry request for transmitting a setting request may be used.

  For example, the transmission timing is included in the retry request, and this transmission timing is made different for each wired terminal 21. Then, the main device 1 transmits a retry request to each wired terminal 21, and each wired terminal 21 sends a signal and a parent-child setting request based on the transmission timing included in the retry request received from the main device 1. Adjust the output timing. Alternatively, the main device 1 may send a retry request to each wired terminal 21, and each wired terminal 21 that has received the retry request from the main device 1 may arbitrarily adjust the output timing of the cue and parent-child setting request. .

  In the present embodiment, the wireless terminal 22 is connected to the wired terminal 21 having a parent-child relationship with the wireless terminal 22 via the extension network 4 and the wireless AP 3. However, the present invention is not limited to this. By mounting a wireless interface on the wired terminal 21, the wireless terminal 22 may be directly connected to the wired terminal 21 having a parent-child relationship with the wireless terminal 22 via a wireless network. Alternatively, the wireless terminal 22 may be directly accommodated in the main apparatus 1 (connected without going through the wired terminal 21). That is, the main device 1 may switch the connection destination of the call path between the wired terminal 21 and the wireless terminal 22 having a parent-child relationship.

  In the present embodiment, the case where a wireless LAN is used for wireless communication of the wireless terminal 22 has been described. However, the present invention is not limited to this. A PHS or a mobile phone may be used for wireless communication of the wireless terminal 22.
