Description

  The present invention relates to a cordless telephone including a parent device and a child device.

  Cordless telephones having a telephone book function are known (see, for example, Patent Documents 1 and 2). In a cordless telephone, a telephone book function is installed in all of a plurality of terminal devices (parent device and child device). Things are common. Therefore, when it is desired to register the same phone book data in all the terminal devices, the user needs to perform an operation of registering the same phone book data in all the terminal devices.

  Also, recent products that have a copy function of telephone directory data are known. However, in such a cordless telephone, the user needs to copy the phone book data separately from the work of registering the phone book data. Moreover, with the normal copy function, the number of terminals that can be copied at one operation is limited to one, so if you want to copy the phone book data to all terminal devices, repeat the copy operation for the number of terminal devices. Need to do.

  Also, terminal devices with different shapes, such as the base unit and handset, have different button operations for phone book registration, so the user can remember each operation or operate while looking at the instruction manual. Must. Therefore, when a plurality of terminal devices are provided, the more the number of terminal devices is, the more time is required to register and update the phone book data.

  Examples of the problems to be solved by the present invention include the above. An object of the present invention is to provide a cordless telephone capable of registering, changing, and deleting telephone directory data in all terminal devices by one simple operation.

The invention according to claim 1 is a cordless telephone including a plurality of terminal devices including a parent device and a child device, wherein each of the plurality of terminal devices is a user for each registered data corresponding to an individual telephone number. A storage unit for storing telephone book data including synchronization information that indicates whether synchronization with other terminal devices is set, and detection for detecting that the user has performed work input on the telephone book data Means, first processing execution means for executing processing of the phone book data stored in the storage unit in accordance with the work input, processing data indicating the contents of the processing of the phone book data, Based on the processing data, the transmission means for transmitting to all the terminal devices, the receiving means for receiving the processing data from other terminal devices, and the phone book data stored in the storage unit Second processing execution means for executing the same processing as the processing of the telephone directory data performed in the terminal device of the data transmission source, and the detection means according to the input of the user A means for detecting that a setting change has been made as to whether or not information can be synchronized; and wherein the transmission means is a registration in which the synchronization information is set to be synchronizable among the registration data subject to the work input. only the processing data corresponding to the data, the process data have a change processing unit for transmitting said to all the other terminal devices on the basis of the synchronization information after means, and setting change is sent to all other terminal devices The change processing means transmits registration data corresponding to the synchronization information to all the other terminals when the synchronization information after the setting change is set to enable synchronization, and the synchronization information after the setting change is Characterized that you send a deletion instruction for deleting registration data corresponding to the synchronization information to all of said other terminals when set in the period allowed.

One embodiment of the present invention is a cordless telephone including a plurality of terminal devices including a parent device and a child device, and each of the plurality of terminal devices includes a user for each registration data corresponding to an individual telephone number. A storage unit for storing telephone book data including synchronization information that indicates whether synchronization with other terminal devices is set, and detection for detecting that the user has performed work input on the telephone book data Means, first processing execution means for executing processing of the phone book data stored in the storage unit in accordance with the work input, processing data indicating the contents of the processing of the phone book data, Based on the processing data, transmission means for transmitting to all terminal devices, receiving means for receiving the processing data from other terminal devices, and telephone book data stored in the storage unit, Second processing execution means for executing the same processing as the processing of the telephone book data performed in the terminal device of the transmission source of the physical data, and the detection means according to the input of the user, It has means for detecting that setting change has been made regarding whether or not synchronization information can be synchronized, and the transmission means is set to allow synchronization in the registered data that is the target of the work input. Means for transmitting only the processing data corresponding to the registered data to all other terminal devices, and change processing means for transmitting the processing data to all the other terminal devices based on the synchronization information after the setting change. When the synchronization information after the setting change is set to allow synchronization, the change processing means transmits registration data corresponding to the synchronization information to all the other terminals, and the synchronization information after the setting change That sends a deletion instruction for deleting registration data corresponding to the synchronization information to all of said other terminals when set in the synchronization disabled.

  The cordless telephone includes a plurality of terminal devices including, for example, one parent device and one or a plurality of child devices. Each terminal device includes a storage unit that stores telephone directory data. Further, when the user performs work input on the phone book data, for example, registration, editing, and deletion of the phone book data, this is detected, and the processing corresponding to the work input is stored in the storage unit of the terminal device. Execute for phone book data. In addition to this, each terminal device transmits processing data indicating the content of processing corresponding to the work input to all other terminal devices.

  The terminal device that has received the processing data from the other terminal device executes the same processing as the processing performed on the phone book data in the terminal device of the transmission source based on the processing data. As a result, the phone book data of the terminal device on the receiving side is in the same state as the phone book data of the terminal device on which the user has entered the work. That is, synchronization of the phone book data is ensured.

  Therefore, if a user performs a necessary work input to one of a plurality of terminal devices, the contents can be automatically reflected on all other terminal devices. Uniform management of book data can be easily performed. Further, the terminal device on which the user inputs work is not limited to the parent device or the specific child device, and any terminal device may be used. Work input related to registration and the like may be performed. For example, if a single member of a family is using multiple slave units, each person does not need to use the master unit, but can use a terminal device that they are familiar with. Often, it is not necessary to learn how to operate many terminal devices such as a parent device and a plurality of child devices. Therefore, it becomes possible to easily synchronize the phone book data of the cordless telephone.

Further, the telephone directory data of the cordless telephone includes synchronization information set by the user for each registration data corresponding to each telephone number, and the transmission means includes the registration data that is the target of the work input. Only the processing data corresponding to the registration data in which the synchronization information is set to enable synchronization is transmitted to all the other terminal devices.

According to this, the user can arbitrarily set registration data that is synchronized and registration data that is not synchronized in all the terminal devices. Therefore, for registration data that should be shared by multiple users, if the synchronization information is made synchronizable, when the registration data is edited in any of the terminal devices, the editing content is automatically This is reflected in all terminal devices. On the other hand, for registration data that each terminal device user wants to manage independently, if the synchronization information is set to non-synchronizable, the registration data will not be synchronized with all terminal devices, Use and management.

In a preferred example of the cordless telephone set, the detection unit includes a unit that detects that a setting change has been made regarding whether or not the synchronization information can be synchronized , in response to an input from the user, and the transmission unit includes: Based on the synchronization information after the setting is changed, the processing data is sent to all the other terminal devices. Thereby, even if a user sets synchronous information at the time of new registration of registration data, and changes it afterwards, the synchronization in each terminal device is controlled according to the changed synchronous information.

  Specifically, the change processing means transmits registration data corresponding to the synchronization information to all the other terminals when the synchronization information after the setting change is set to enable synchronization, and after the setting change When the synchronization information is set to be non-synchronizable, a deletion instruction for deleting the registration data corresponding to the synchronization information can be transmitted to all the other terminals. Thus, the registration data in each terminal device is managed according to the changed synchronization information.

  In another aspect of the cordless telephone set described above, the reception unit transmits a receipt confirmation signal to the transmission source terminal device when the processing data is received from the transmission source terminal device, and the transmission source terminal device Transmission means of the terminal device stores the other terminal device that has not received the receipt confirmation signal as an error terminal, and retransmits the processing data to the error terminal at a predetermined timing. Means.

  In this aspect, when the processing data corresponding to the work input for the phone book data is transmitted to another terminal device, but the receipt confirmation signal cannot be received, the terminal device is designated as an error terminal for which processing has not been completed. Store as a device. Then, at the appropriate timing, the same processing data is retransmitted to establish synchronization. In this way, by retransmitting the processing data, it is possible to maintain all the terminal devices in a synchronized state as much as possible. In this case, in a preferred example, the re-transmission unit can re-transmit the processing data every elapse of a predetermined time, and re-transmits the processing data when the detection unit detects the work input. be able to.

  In a preferred embodiment, the work entry for the phone book data includes registration, deletion, editing of a part or all of the phone book data, and part or all of the phone book data to all other terminal devices. It includes at least one copy instruction for copying. As a result, various processes for the telephone directory data can be reflected in all the terminal devices.

[First embodiment]
Next, the first embodiment will be described. FIG. 4 is a functional block diagram showing a schematic configuration of a part related to the processing of the telephone directory data according to the first embodiment. As shown in the figure, the cordless telephone is configured such that the parent device 110a and the child device 110b can communicate with each other via the antenna units 6 and 21, respectively.

  As illustrated, the base unit 110a includes a main control unit 111a, a display unit 112a, an operation unit 113a, a radio unit 114a, and a storage unit 115a. The main control unit 111a performs necessary control over the entire data transmission / reception process from the parent device 110a to the child device 110b, or vice versa, in addition to the call processing using the parent device 110a. . In addition, the storage unit 115a records registration data registered by the user in the parent device 110a or the child device 110b as telephone directory data.

  On the other hand, the slave unit 110b includes a main control unit 111b, a display unit 112b, an operation unit 113b, a wireless unit 114b, and a storage unit 115b, and the functions of each unit are the same as those of the master unit 110a. In the following description, if it is not necessary to distinguish between the constituent elements of the master unit or the slave unit, the suffix is omitted. For example, “main control unit 111a” refers to the main control unit of the parent device, and “main control unit 111” refers to either the main control unit of the parent device or the child device. To do.

  FIG. 5A is a block diagram showing an internal structure of the storage unit 115 shown in FIG. The storage unit 115 includes a telephone directory memory 116a, a transmission history memory 116b, a reception history memory 116c, and other memory 116d that records error terminal data described later.

  An example of the phone book data 135 stored in the phone book memory 115a is shown in FIG. As illustrated, the phone book data 135 includes a plurality of registration data 136. One registration data 136 corresponds to one telephone number, and each registration data 136 includes the name of the other party, a telephone number, an electronic mail (E-mail) address, and the like.

  Next, telephone book data registration processing according to the first embodiment will be described. In the first embodiment, the user uses any one of the master unit 110a and the slave unit 110b constituting the cordless telephone 100 to input, for example, registration, deletion, and editing of phone book data (hereinafter referred to as “work input”). ”Is reflected on all other parent devices 110a and 110b (this is referred to as“ synchronize ”). Specifically, when the work entry of the phone book data is made to the parent device 110a, the contents are automatically transmitted to all the child devices 110b and reflected. On the other hand, when the work entry of the phone book data is made to one slave unit 110b, the contents are automatically transmitted and reflected to the master unit 110a and all the other slave units 110b.

  In the present embodiment, since the user can input the work of the telephone directory data not only to the parent device 110a but also to the child device 110b, hereinafter, the “terminal device” including the parent device 110a and the child device 110b will be described. 110 ".

  The phone book data registration process according to the first embodiment will be described below. FIG. 6 is a process flowchart in a terminal device (hereinafter also referred to as “transmission source terminal device”) used when the user registers telephone directory data. FIG. 7 is a process flowchart in a terminal device other than the transmission source terminal device (hereinafter also referred to as “reception-side terminal device”). The processing of each flowchart can be realized mainly by the main control unit 111 in each terminal device 110 executing a control program prepared in advance.

  In FIG. 6, first, the main control unit 111 of the terminal device 110 determines whether or not the phone book registration by the user is completed (step S1). The phone book registration is generally performed when the user performs a predetermined button operation or the like, sets the terminal device 110 in the phone book registration mode, and inputs necessary information such as a phone number and a name. One case of information corresponding to one telephone number input in this way is stored as one registration data 136 described above. When the user inputs an instruction such as completion of phone book registration, the terminal device 110 detects this and knows that phone book registration has been completed.

  When it is detected that the phone book registration is completed, the main control unit 111 of the terminal device 110 stores the data input by the user in the storage unit 115 as registration data (step S2).

  Next, the main control unit 111 sets the input registration data in a transmission packet to another terminal device (step S3). Since data communication between the terminal devices 110 is performed in the form of a packet in a predetermined format, registration data to be transmitted to other terminal devices 110 is set in the transmission packet.

  Next, the main control unit 111 sets a transmission destination terminal (step S4). Since the registration data input by the user is sequentially transmitted to all other terminal devices 110, the main control unit 111 first sets one terminal device 110 as a transmission destination terminal. The setting order of the transmission destination terminals can be determined in advance, and the transmission destination terminals are sequentially changed each time the process of step S4 is performed.

  Next, the main control unit 111 transmits a packet including registration data (step S5), and determines whether or not an acknowledgment signal (ACK signal) from the transmission destination terminal has been received (step S6). When the reception confirmation signal is not received, the main control unit 111 temporarily records the transmission destination terminal as an error terminal (step S7). This error terminal information can be stored in, for example, the other memory 116d shown in FIG. The main control unit 111 stores the identification information of the terminal device as information on the error terminal, and saves registration data or transmission packet data transmitted when an error occurs for retransmission processing described later. To do. On the other hand, if a receipt confirmation signal has been received, the process proceeds directly to step S8.

  Next, the main control unit 111 determines whether or not a packet including the registration data has been transmitted to all the terminal devices 110 (step S8). If there is an untransmitted terminal device 110 ( Step S8; No), the process returns to step S4. In step S4, the next terminal device 110 is set as a transmission destination terminal, and the processes in steps S5 to S8 are repeated.

  In this way, when the main control unit 111 confirms that the packet has been transmitted to the terminal device 110 with which the user has registered the phone book, that is, all the terminal devices 110 other than the transmission source terminal device 110 (step S8; Yes) ), The main control unit 111 performs a retransmission process to the error terminal (step S9), and ends the process. The retransmission process will be described later.

  Next, processing in the receiving terminal device 110 will be described. FIG. 7 shows a processing flowchart in the terminal device 110 on the receiving side. In the terminal device 110 on the receiving side, the main control unit 111 determines whether or not the wireless unit 114 has received the above-described packet (step S11). When receiving the packet, the main control unit 111 extracts registration data from the packet, and stores the registration data in the storage unit 115 as telephone directory data (step S12).

  In addition, since the above example is a case where the user newly registers the phone book data as an example of the work input for the phone book data, the process corresponding to the work input sent from the transmission source terminal to the reception side terminal The data was registered data itself. Similarly, the registration data already stored in the storage unit 115 can be edited (change of contents) or deleted. For example, when the user changes the e-mail address of specific registration data using a certain terminal device, the processing data corresponding to the work input includes all other information indicating the change and the change instruction. The e-mail address is changed. Further, when the user deletes specific registration data, an instruction to delete the registration data is transmitted to all other terminal devices as processing data corresponding to the work input, and the registration data is deleted.

  As described above, in the present embodiment, when the user inputs the work of the phone book data to either the parent device or the child device, the contents are automatically transmitted to all other terminals, and the transmission destination Similar processing is performed on the phone book data of the terminal. For example, when the user newly registers in the phone book data using the parent device, the contents are automatically transmitted to all other terminal devices and stored. Similarly, when a user deletes or edits registration data that has already been registered using a slave unit, the contents are reflected in the phone book data stored in the master unit and all other slave units. Is done.

  Therefore, the user does not need to perform the same work input individually for the master unit and all the slave units, and does not need to send the work input performed for the master unit to all the slave units in order by a copy function or the like. In addition, the contents of the phone book data of all the terminal devices can be matched. That is, only by the user performing necessary work input to the master unit or any one of the slave units, synchronization of the phone book data stored in the master unit and all the slave units is ensured. In addition, even if the user does not learn the operation method of all the terminal devices, the user can register, edit, delete, etc. the phone book data stored in all the terminal devices as long as the user can learn the operation method of one terminal device. be able to.

  In the above example, all the terminal devices constituting the cordless telephone have the same phone book registration function, but only one terminal device is provided with the phone book registration function, and other terminal devices. The phone book registration function can be deleted from the program to save program storage capacity.

  Next, the retransmission process to the error terminal will be described. The retransmission process to the error terminal means that the main control unit 111 transmits the packet again to the terminal device 110 recorded as the error terminal at that time. As described above, since the terminal device that could not receive the receipt confirmation signal in the past process is temporarily recorded as the error terminal, the main control unit 111 sends the error terminal to the error terminal at that time, that is, the past error. The packet sent at the time of occurrence is sent again. If the receipt confirmation signal is obtained, the record of the error terminal is deleted. On the other hand, when the receipt confirmation signal is not obtained even by the retransmission process, the record as the error terminal is maintained, and the retransmission is performed at the next timing. In order to realize the retransmission process, each terminal device 110, in addition to the identification information of the error terminal, the packet itself transmitted at that time or the processing data included in the packet (registration data, registration data editing instruction) , Registration data deletion instructions, etc.) must be stored.

  Step S9 shown in FIG. 6 performs the above-described re-transmission process every time a user's work input is performed on the phone book data. Note that, instead of performing the re-transmission process at the time of the user's work input for the phone book data as in step S9, or in addition to that, the main control unit 111 executes the re-transmission process every predetermined time. Is preferred. As a result, even when the work input by the user is not performed for a relatively long period of time, the retransmission processing is periodically performed to establish and maintain a state in which all the terminal devices are synchronized with the same telephone directory data as much as possible. It becomes possible.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the first embodiment, all registration data included in the phone book data is synchronized with the phone book data stored in all other terminal devices. On the other hand, in the second embodiment, the user can set whether or not synchronization is possible for each registration data, and only the registration data set as synchronization possible is synchronized.

  FIG. 8 shows an example of telephone directory data according to the second embodiment. In the telephone directory data of this embodiment, as shown in the figure, synchronization information is set for each registration data. The synchronization information is information indicating whether or not the registration data is registered in the parent device 110a and all the child devices 110b (that is, synchronization is performed), and is set for each registration data 136 by the user. The synchronization information is set to either “synchronization is possible” or “synchronization is impossible”. When the synchronization information is set to “synchronizable”, the registration data 136 is registered, deleted, edited, and the like in the same manner in all the terminal devices including the parent device 110a and the child device 110b. On the other hand, when the synchronization information is set to “unsynchronizable”, processing such as registration, deletion, and editing of the registration data 136 is executed only in the parent device 110a or the child device 110b for which the user has input. It is not reflected in other terminal devices. The synchronization information is set by the user when the registration data 136 is registered for the first time, but can be arbitrarily changed by the user thereafter.

  In this way, by setting whether or not synchronization is possible for each registered data, it becomes possible to partially change the phone book data stored in each terminal device. For example, if multiple handsets are used by each family member, set the registration data related to the whole family to be synchronizable, and set the registration data used only by each person to be non-synchronizable. Can do. In this way, each user can customize the phone book data of the terminal device that he / she mainly uses while sharing the necessary data with everyone.

  The processing of the transmission source terminal device in the second embodiment is basically the same as that of the first embodiment shown in FIG. However, in the first embodiment, all the registration data registered in the telephone book by the user in step S1 in FIG. 6 is set in a transmission packet in step S2 and transmitted to all other terminal devices. On the other hand, in the second embodiment, in the process corresponding to step S2, only registered data whose synchronization information is set to be synchronizable is extracted and set in a transmission packet to all other terminal devices.

  FIG. 9 shows processing executed instead of step S2 of FIG. 6 in the second embodiment. When the user performs telephone directory registration in step S1 of FIG. 6, as shown in FIG. 9, the main control unit 111 determines whether or not the registration data input by the user is set to be synchronizable (step S21). Then, the main control unit 111 sets the registration data in the transmission packet if the synchronization is set (step S22), and sets the registration data in the transmission packet if the synchronization is not set. Do not set.

  Next, the main control unit 111 determines whether or not the determination in step S21 has been completed for all the registration data input in step S1 (step S23). In this way, only all of the registered data that is set as the input target in step S1 is set in the transmission packet so that synchronization is possible. Then, the process returns to the main routine shown in FIG. 6, and step S3 and subsequent steps are executed. In this way, only the registration data set to be ready for synchronization is transmitted to all other terminal devices. The processing in the receiving terminal device is the same as the processing in the first embodiment shown in FIG.

  Next, the synchronization information editing process will be described. In the second embodiment, after the user sets the synchronization information at the time of new registration for each registration data, it can be arbitrarily changed. A process for changing the synchronization information will be described with reference to FIGS. FIG. 10 is a flowchart of processing performed at the transmission source terminal in the synchronization information editing processing. In this case, the transmission source terminal refers to a terminal used when the user edits synchronization information.

  In FIG. 10, when the user edits the synchronization information (step S31), the main control unit 111 of the terminal device 110 determines whether the editing is completed (step S32). When the editing is completed, the main control unit 11 determines whether or not the editing is changed from synchronization impossible to synchronization possible (step S23). When the editing is to change from synchronization impossible to synchronization possible, the main control unit 111 transmits a registration instruction including the registration data to all other terminals (step S24). On the other hand, if the editing is to change from synchronization possible to synchronization impossible (step S23; No), the main control unit 111 transmits an instruction to delete the registered data to all other terminal devices (step S25). Thus, the process at the transmission source terminal ends.

  Next, processing in the receiving terminal is shown in FIGS. FIG. 11A shows processing when the receiving terminal device 110 receives the registration instruction transmitted in step S24. When the registration instruction is received from the transmission source terminal apparatus 110 (step S41), the main control unit 111 of the receiving terminal apparatus 110 already includes the registration data included in the registration instruction in the phone book data of the terminal apparatus. It is determined whether or not (step S42). If it is included, the main control unit 111 updates the registration data (step S43). If not included, the main control unit 111 newly stores the registration data (step S34).

  FIG. 11B shows processing when the receiving terminal device 110 receives the delete instruction in step S25. When receiving the deletion instruction from the transmission source terminal device 110, the main control unit 111 of the reception-side terminal device 110 determines whether or not registration data to be deleted is already stored in the terminal device (step S46). . Then, the main control unit 111 deletes the registration data from the phone book data if stored (step S47), and ends the process as it is if not stored.

  As described above, when the user changes the synchronization information afterwards, the phone book data stored in all the terminal devices can be changed by changing all the other terminal devices in accordance with the change contents. Can be ensured.

  Next, copy processing in the second embodiment will be described. The cordless telephone 100 of the present invention may be equipped with a batch copy function for copying all registered data included in the phone book data from one terminal device to another specific terminal device or all other terminal devices. Is possible. According to the second embodiment, the batch copy process using the copy function is performed with reference to the synchronization information. FIG. 12 shows a flowchart of copy processing in the second embodiment.

  In FIG. 12, when the user operates one terminal device 110 to input a batch copy instruction, the main control unit 111 of the terminal device 110 is included in the phone book data stored in the terminal device 110. The registration data is read (step S51), and it is determined whether or not the synchronization information of the registration data is set to allow synchronization (step S52). If the synchronization is set, the main control unit 111 transmits the registration data to the terminal device 110 designated as the transmission destination terminal (step S53).

  Then, the main control unit 111 determines whether or not processing has been completed for all registration data included in the phone book data (step S54). In this way, only all of the registered data included in the phone book data stored in the terminal device that is set to be synchronizable is transmitted to the designated destination terminal device. The destination terminal device stores the registration data in the phone book data. In this way, the batch copy process is executed. As described above, according to the second embodiment, even in the batch copy process, only registered data set to be synchronizable is copied, and all terminal apparatuses are synchronized.

  In the flowchart of FIG. 12, the registration data set to be ready for synchronization is transmitted one by one in step S53. However, the registration data to be transmitted is collected and transmitted to the destination terminal device at one time. It doesn't matter. In the example of FIG. 12, all the phone book data stored in the terminal device used by the user is copied at once, but the user has specified one or more registered data selected by the user. You may copy to a specific terminal device or all the other terminal devices.
