Abstract

PURPOSE:To quickly transfer a variable data by transferring the subscriber variable data of one exchange to the subscriber variable data storage area of other exchange depending on a prescribed procdure operation. CONSTITUTION:A signal received by a signal reception means 32 via a common signal line 20 is inputted to a signal analysis means 42, where the signal is analyzed. When the means 42 analyzes the transfer preparation end signal of a variable data as reception, the information of variable data transfer is sent to a data read means 43 together with the reception information. The means 43 inhibits the change of a storage data in the variable data storage area 51 taking the transfer sender subscriber number of the storage means 61 as an address and reads the storage content as the transfer data. The read data is transferred to a data edition means 44, where the data is edited into a prescribed transmission signal and sent to a common signal line 20 via the signal transmission means 33. When the transfer data is transferred normally and registered at a transfer destination exchange 12, the means 42 receives and analyzes it and sends the result to the means 43.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention allows variable data set by a subscriber from a terminal to be transferred between exchanges among data for each subscriber number stored in a storage device of an exchange and used for exchange processing. This invention relates to a subscriber variable data transfer method for transferring data.

[Conventional technology]

In the conventional subscriber variable data transfer system, the subscriber sets the data again from the terminal at the transfer destination. Similarly to the transfer of fixed data, there is a method of reading variable data onto magnetic tape and writing it at the transfer destination. It is not normally used because it disables the setting.

[Problem that the invention seeks to solve]

In the conventional subscriber variable data transfer method described above, the subscriber writes variable data directly at the transfer destination terminal, so the subscriber must sequentially write a large amount of variable data required for service functions that have been rapidly increasing in recent years. However, there were problems in that it not only took time but also was prone to errors, resulting in a decline in service.

[Failure to solve the problem]

The subscriber variable data transfer system of the present invention is for transferring variable data between exchanges without going through subscribers.

The present invention includes means for transferring subscriber variable data stored in a storage device according to a predetermined procedure to a storage area of a transfer destination exchange via a signal line.

That is, the exchange includes a signal transmission device for transmitting data between the exchanges, a storage device having a variable data storage area of the subscriber, and upon receiving a predetermined instruction, transmits the signal from the variable data storage area to the storage area of the destination exchange. It has a central control unit that transmits variable data through the device and writes the variable data into a designated storage area when the variable data is received through the signal transmission device.

FIG. 1 is a diagram corresponding to claims of the present invention. The exchange 1 is coupled to a signal line 2, and signals and data exchanged by the exchange 1 are transmitted via the signal line 2. Communication information with the terminal includes audio, images, data, etc., and is transmitted via a communication channel (not shown). The exchange l has a signal transmission device 3 that terminates the signal line 2 and sends and receives signals, etc., a central control device 4 that controls switching processing, and a memory having a variable data storage area 5 that stores variable data corresponding to subscriber numbers. It has a device 6. The central control device 4 is the destination exchange 1 of the subscriber terminal.
The variable data is read out from the variable data storage area 5 and sent to the signal IM2, and the destination exchange 1 executes variable data transfer control in which the received variable data is written to a predetermined location in the variable data storage area 5.

〔Example〕

Next, the subscriber variable data transfer system of the present invention will be explained with reference to the drawings.

The central control unit explained in the complaint correspondence diagram of FIG. 1 executes various functional means by making full use of the programs and data stored in the storage device.

FIG. 2 is a functional block diagram showing one embodiment of the present invention. In Figure 2, the destination exchange 1 to which the subscriber terminal was transferred
1 and the transfer destination exchange 12 is a communication channel (not shown).
Separately, a common line signal system is adopted in which signals are transmitted and received by coupling via a common signal line 20. The signal transmission devices connected to the common signal line 20 include signal sending means 31, 33 and signal receiving means 32, 34, and the functions of the central control unit include variable data transfer setting means 41. Signal analysis means 42, 45° data input/output means 43, 46. and data editing means 44,
Further, as storage devices, storage means 61 and 62 each having variable data storage areas 51 and 52 for each subscriber number are provided.

In FIG. 2, the variable data transfer setting means 41 of the transfer destination exchange 12 receives the transfer source and transfer destination subscriber numbers and the variable data transfer request signal by operating the maintenance and operation tool, and sets the transfer. Subscriber variable data is data set by the subscriber from the terminal and data that is rewritten by the exchange each time an event occurs, and is included in the subscriber data for each subscriber used for exchange processing and is indexed from the subscriber number. .

Therefore, the normal maintenance and operation tool first registers the subscriber number at the destination exchange. The transfer destination subscriber number is specified using this registration number. If the transfer source subscriber number is transferred between stations, a station number is added, and if it is transferred to a different area, a region code is added. The variable data transfer setting means 41 sends a variable data transfer request signal added to the subscriber number for the transfer source exchange 11 and the subscriber number for the transfer destination exchange 11 and the transfer destination exchange 12 according to the transfer setting. The variable data storage area 5 of the storage means 62 is sent along with the variable data write signal, and the same information is transferred to the data input/output means 46 and the address is the subscriber number of the transfer destination.
Prohibits changes to the memory contents of 2.

The signal analysis means 42 of the transfer destination exchange 11 analyzes the signal received by the signal reception means 32 via the common signal line 20,
When the variable data transfer request signal is received, the received information is transferred to the data input/output means 43, and an instruction is given to read out the data stored in the variable data storage area 51 of the storage means 61 using the subscriber number as an address. The data input/output means 43 prohibits modification of the variable data stored in the stored contents for the designated subscriber number, reads out the variable data, and outputs it to the data editing means 44.

The prohibition of changing the variable data is canceled when a registered signal of normal reception is received from the destination exchange 12 and the stored contents of the transferred variable data storage area 51 are erased together with the subscriber number. The data editing means 44 edits the received variable data together with the subscriber number used as the read address, the exchange code of the data transfer destination, and the variable data transfer signal according to a predetermined signal format, and sends the edited data to the common signal line via the signal sending means 33. Send on 20th.

The signal analysis means 45 of the transfer destination exchange 12 is the signal reception means 3
4 analyzes the signal received via the common signal line 20 as a fully variable data transfer signal, transfers the received information to the data input/output means 46 as reception of transfer data. The data input/output means 46 compares the subscriber number of the transfer source added when the transfer data is received with the subscriber number of the transfer source obtained from the variable data transfer setting means 41, and uses the subscriber number of the transfer destination as an address. The received data is written and registered in the variable data storage area 52 of the storage means 62, and when the registration is successful, a registered signal is sent to the transfer destination exchange 11 via the signal sending means 31. When an abnormality is discovered and cannot be registered, the data input/output means 46 notifies the user with an alarm.

If variable data is to be retransmitted, a warning will be issued and the variable data transfer settings will be restarted from the beginning. Data input/output means 46
It is also possible to send a retransmission signal to the variable data transfer setting means 41 for automatic retransmission.

FIGS. 3 and 4 are flowcharts showing an example of the main operating procedures at the transfer destination and transfer source in FIG. 2, respectively.

The main operating procedures of the destination exchange will be explained with reference to FIG. 3 and FIG. 2. It is assumed that the maintenance operator has previously registered the subscriber number of the subscriber who is the transfer target together with the fixed data in the subscriber data. The procedure begins by specifying the code of the variable data transfer request and the subscriber numbers of the transfer source and transfer destination, respectively, so that the variable data transfer setting means 41 sets the start of transfer of variable data (operation procedure (2)). When the variable data transfer setting means 41 sets the transfer of variable data, it transfers the information to the data input/output means 46, and prohibits changes to the data stored in the variable data storage area 52 of the subscriber number of the transfer target subscriber at the transfer destination. (Operation procedure ■), and then transmits information indicating that the setting is completed to the common signal line 20 via the signal sending means 31 as a predetermined variable data transfer preparation completion signal (operation procedure ■). Next, the signal received by the signal receiving means 34 via the common signal line 20 is input to the signal analyzing means 45, which confirms the reception of the transferred data and performs a code check (operation procedure ①). Received data is judged to be normal (
When the operation procedure ■) is performed, the received data is transferred to the data input/output means 46 together with the additional information, and is written into the variable data storage area 52 whose address is the transfer destination subscriber number of the storage means 62, and is registered (operation procedure ■). Ru. When the data input/output means 46 completes registration, the registered signal is sent to the signal sending means 31.
At the same time, the transfer destination exchange 12 displays that it has been registered (operation procedure ■), and cancels the inhibition of data changes in the variable data storage area 52 (operation procedure ■).

On the other hand, if the received information is determined to be abnormal in the operation procedure (2), the reception abnormality is displayed (operation procedure (2)), and the process continues to the operation procedure (2) for canceling the data change prohibition. In this embodiment, it has been explained that in the case of abnormal reception, the settings are set again and the transfer is executed, but it is also possible to automatically reset the settings in case of an abnormality and repeat the procedure from the beginning.

Next, with reference to FIG. 4 and FIG. 2, the main operating procedures of the destination exchange will be explained. The signal received by the signal receiving means 32 via the common signal line 20 is input to the signal analyzing means 42 and analyzed. When the signal analysis means 42 receives the variable data transfer preparation completion signal (analyzes that the operation procedure is 0), it transmits variable data transfer information to the data reading means 43 together with the received information. It prohibits changes to the data stored in the variable data storage area 51 whose address is the former subscriber number (operation procedure ■), and reads the stored content as transfer data (operator 1m@).The read data is stored in the data editing means 44, is edited into a predetermined transmission signal, and is sent to the common signal line 20 via the signal transmission means 33 (operation procedure ■).The transferred data is transferred normally and registered in the destination exchange 12. When the signal analysis means 42 receives and analyzes the registered signal (operation procedure [phase]) and sends it to the data input/output means 43, the data input/output means 43 stores the variable data storage area 5 of the transfer source subscriber number.
The recorded data of No. 1 is erased (operation procedure [phase]) and the inhibition of data change is canceled (operation procedure ■).

In the above embodiment, for one transfer target subscriber, when making the subscriber terminal available at the transfer destination, the transfer destination exchange specifies variable data transfer settings and automatically instructs the transfer to the transfer source exchange. A case has been described in which the destination exchange receives and stores the transferred data.

As another example, when transferring all subscribers from an old station to a new station, there is no need to prohibit data changes because the destination exchange is a new station and is not in service.
Both the operating procedures (■) and (■) in the flowchart of FIG. 3 may be deleted.

Furthermore, since the transfer source exchange is in service, it is necessary to delete the operation procedure (2) in the flowchart of FIG. 4 and leave the data. In addition, when transferring to a new station, the data transfer operation is repeated by sequentially searching the subscriber numbers of the subscribers to be transferred, and the above-mentioned data input/output means has the function of determining whether or not all the subscribers to be transferred have been searched. has.

In the above embodiment, the setting for variable data transfer is specified at the destination exchange, but it may also be specified at the source exchange.If an abnormality is detected in the received data, the destination exchange notifies the transfer source, that is, the data transfer source, of the abnormality.

The functional means explained in the above embodiments can be changed depending on the configuration of the program, and are not limited to the above explanation. Although the variable data transfer setting means has been described as being provided in the transfer destination exchange, it can also be provided at the transfer source or from any location. Although the transfer source and transfer destination have been explained separately, one exchange has both functions. Further, the operating procedure is not limited to the above explanation, and any method may be used as long as the function can be achieved even if there is a sequential order or a series/parallel operation.

〔Effect of the invention〕

As explained above, the subscriber variable data transfer method of the present invention transfers the subscriber variable data of one exchange to the subscriber variable data storage area of another exchange by performing predetermined procedures. By equipping the exchange with a central control device and a signal transmission device, there is an effect of improving the service in that variable data can be transferred quickly and accurately.
