DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. FIG. 1 is a processing flow chart showing an embodiment of the present invention, FIG. 2 is a block diagram showing an example of a switching system to which the present invention is applied (only the portion related to the present invention), and FIG. 3 is a configuration example of a number translation database. FIG. 4, FIG. 4 is a diagram showing a configuration example of a routing database, and FIGS. 5, 6, and 7 are diagrams showing display examples of a command input screen and a command response screen when receiving a number translation database update command.

In FIG. 2, the switching system includes a call processor 10, a maintenance operation management processor 20, and two (first and second) backups which alternately share the latest generation and the immediately preceding generation. Number translation database 81,
It has a disk device 30 storing 82, and a maintenance terminal 40 for inputting a command by a maintenance person from a keyboard and displaying a command response on a display. The call processor 20 controls reading and writing of various databases (80, 90) to and from the main storage unit 15 that stores various data and programs such as the current number translation database 80 and the routing database 90. Basic call control that performs call connection and call release while transmitting and receiving various signals between the database control unit 16, the protocol control unit 12 that performs various protocol control of the user / network interface and the inter-network interface, and the protocol control unit 12. Section 11, and a translator section 14 for indexing the number translation database 80 by using the called area code as a key and determining the corresponding route index based on the called subscriber number received by the request from the basic call control section 11,
In response to a request from the basic call control unit 11, the routing database 90 is indexed using the route index as a key to obtain corresponding routing information, and a routing resource management unit 17 for selecting an empty line in the route determined by the routing information, and a basic call It has a switch control unit 13 for connecting / disconnecting a communication path (path) according to a request from the control unit 11. The maintenance operation management processor 20 analyzes the command input from the maintenance terminal 40, analyzes and executes the command, and responds to the command from the maintenance terminal 40 via the command control unit 22 in the disk device 30. The backup number translation databases 81 and 82 are updated, such as changed, added, and deleted, and the current number translation database 80 in the main storage unit 15 of the call processor 10 is updated. There is.

The structure of the number translation database is common to the current number translation database 80 and the first and second backup number translation databases 81 and 82 (see FIG. 3). Incoming area code 3 is the top n of called subscriber number 7
The digits represent up to the number of digits for which the route index 4 is determined. The route index 4 represents a route in the case of a relay exchange (for example, the direction of Tokyo, the direction of Osaka, etc.). This number translation database is composed of a plurality of tables connected in a tree shape according to the value of each digit of the incoming call area code 3, and in FIG.
-1, ..., 3- (n-1), 3-n) related tables 800-1, ..., 800- (n-1), 800-n)
Only shows. These tables 800-1 to 80
In 0-n, each digit of the incoming area code 3-1 to 3-3-
When indexed by the value of n, the identification flags 810 are obtained. When the identification flag 810 indicates that there is a succeeding digit, the succeeding data is interpreted as a next table pointer indicating the start position of the next table, and the corresponding table is continuously indexed by the value of the next digit of the incoming area code. The identification flag 810 is relayed /
When it indicates that it is a subscriber accommodated in its own station, the subsequent data is interpreted as the route index 4, and the index is terminated.

The routing information obtained by indexing the routing database 90 with the route index 4 designating a route is information about a line group (route) existing in the route, for example, a routing system (route selection system). ), The actual route, and the selection method of the line in the route. Like the number translation database, the routing database 90 can also store two backup routing databases of the latest generation and the previous generation in the disk device 30.

Next, the operation will be described with reference to FIGS. Now, the first backup number translation database 8
It is assumed that the first generation is the same generation as the current number translation database 80 (current generation), and the second backup number translation database 82 is the previous generation.

When the number translation database is updated by adding, deleting or changing the incoming call area code and adding, deleting or integrating the route determined by the incoming call area code, the command entry screen of FIG. 5 or 6 is displayed. As shown in 41, when the maintenance person inputs the number translation database update command 1 to the maintenance terminal 40, the mode 2 is set to “update” or “update and test”, and the incoming area code 3 and the route index 4 are designated ( In step S10 of FIG. 1, the maintenance operation management processor 20 recognizes the update instruction of the number translation database (step S10).
11) Through the database control unit 16 in the call processor 10, the routing database 90 is indexed using the designated route index 4 as a key (step S2).
0), the index result is determined (step S21), and if the result is NG (defective), an error display indicating that the routing database 90 is not correctly created for the root index 4 is displayed on the command response screen of the maintenance terminal 40. (Step S22), and the command ends (step S200). If the result is OK (good), as shown in the command response screen 42 of FIG. 5, the routing information 5 obtained by indexing together with the designated incoming area code 3 and route index 4 is displayed (step S30), and maintenance is performed. The update execution confirmation request 6 to the user is displayed (step S4).
0). Further, when the content of the update is a change, the current generation side of the two backup number translation databases 81, 82, in this case, the first backup number translation database 81 (note that the current number translation database is used). 80 may be used) to obtain the registered old incoming call area code 3, old route index 4, and old routing information 5 to be changed, and these are also displayed on the command response screen 42. The maintenance person confirms these information contents displayed on the command response screen 42, decides whether or not execution is possible, and inputs "Y" or "N" as an update execution confirmation response. The maintenance operation management processor 20 determines whether update execution is possible or not according to the input Y / N (step 41), and if it is not possible, terminates the command as it is (step S200). Of the number translation databases 81 and 82, the working generation side, in this case, the first backup number translation database 81 (which may be the current number translation database 80 itself) is read, and the designated incoming area code 3 and route are read. The updated database is updated with the value of the index 4, and the side of the two backup number translation databases 81, 82 which is not the working generation, in this case, the second backup number translation database 82 is rewritten (step S50). ). At this point, the second backup number translation database 82 side is the latest generation, the first
The backup number translation database 81 side is the generation immediately before that, but the working generation is still the first backup number translation database 81 side. Therefore, if there is an error in the updated contents, the updating process can be performed again based on the first backup number translation database 81. After the processing of step S50, the database control unit 21 determines whether the designation of the mode 2 at the time of inputting the number translation database update command 1 is only "update" or "test" is also designated (step S60), and "update" is performed. In the case of "only", it is considered that there is no error even if the final confirmation of the update content is not performed, and the current number translation database 80 in the main storage unit 15 is updated through the database control unit 16 of the call processor 10 to the above-mentioned updated database ( The second backup number translation database 82) is rewritten (step S70), and the command ends through the command control unit 22 (step S200). At this point, the second backup number translation database 82 side becomes the working generation.

The maintenance operation management processor 20 executes the step S.
When it is recognized that "test" is also designated in the determination processing of mode 2 of 60, the following processing for final confirmation of the update content is performed before the update processing of the current number translation database 80. First, the maintenance terminal 40 displays that final confirmation processing is to be performed, and when the maintenance terminal 40 designates an arbitrary incoming call subscriber number 7 to be updated by the maintenance person, the incoming call subscriber number 7 (the incoming call area code included therein) is displayed. 2) with 3) as a key
Of the two backup number translation databases 81, 82, the updated side, in this case, the second backup number translation database 82 is indexed (step S10).
0), the index result is determined (step S101). When the result is NG, an error display indicating that the designated called subscriber number 7 cannot be translated is displayed on the command response screen 42 of the maintenance terminal 40 (step S102). If the result is OK, the routing database 90 is indexed using the root index 4 obtained by indexing as a key (step S11).
0), the index result is determined (step S111). If the result is NG, an error display indicating that the routing processing of the designated called subscriber number 7 is impossible is displayed on the maintenance terminal 40 (step S112). If the result is OK, as shown in FIG. 6, the route index 4 and the routing information 5 obtained by indexing together with the designated called subscriber number 7 are displayed on the command response screen 42 of the maintenance terminal 40 (step S).
120). Processing of step S102, step S112
When either the process of step S120 or the process of step S120 is completed, it is determined whether "update" was also specified in mode 2 of the number translation database update command 1 or only "test", which will be described later, is specified ( Step S
130), if only "test" is specified, the command ends as it is (step S200).

The maintenance operation management processor 20 executes step S
When it is recognized that “update” is also designated in the determination processing of mode 2 of 103, the final update execution confirmation request is issued to the maintenance terminal 40 (the same area as the update execution confirmation request 6 described above).
And the response is accepted (step S140). The maintenance person checks the displayed contents and finally confirms whether the number translation database has been correctly updated. At this time, if another called subscriber number 7 is designated to continue the confirmation work (step S141), the maintenance operation management processor 20 repeats the processing from step S100. After the final confirmation work is completed, the maintenance person determines whether the final execution is possible or not, and inputs “Y” or “N” as the final update execution confirmation response. Maintenance operation management processor 20 is turned on
Whether or not the final update can be executed is determined according to / N (step S142), and if not, the command is terminated as it is (step S200).
The current number translation database 80 of 70 is updated, and the command ends (step S200).

On the other hand, in the acceptance process of the number translation database update command 1 in step S10, if mode 2 is set to "test" and the called subscriber number 7 is specified, the maintenance operation management processor 20 executes the number translation database update process. No, step S100 described above
From step S130 to step S130, the route index 4 and the routing information 5 obtained by indexing the number translation database and the routing database based on the designated incoming subscriber number 7 as shown in FIG. The command response screen 42 of 40 is displayed.

[0016]

As described above, according to the present invention, the incoming call area code and the route index to be updated are designated (input) only once as the number translation database update command by the maintenance person.
The routing information corresponding to the specified route index is searched for by indexing the routing database, displayed to the maintenance personnel, the update execution confirmation request is issued, and it is specified only when the update execution confirmation response is received from the maintenance personnel. Since the backup number translation database is updated based on the incoming call area code and route index, the current number translation database is updated, so the number translation database update command can be used for both backup and current use.
The update procedure is simplified without the need to input it again.

If there is an update confirmation test request from the maintenance person, after the backup number translation database is updated and before the current number translation database is updated, the incoming subscriber number is accepted and the updated backup number is received. The translation database is indexed to obtain the corresponding root index, and the routing database is indexed using this root index to obtain the corresponding routing information, which is displayed to the maintenance personnel and a final update execution confirmation request is issued, and the maintenance personnel confirms the final update execution. Since the current number translation database is updated only when a response is received, it is not necessary to prepare a test terminal and make a test call to confirm the update of the backup number translation database.

Further, when the update execution confirmation request is displayed to the maintenance person, if the registered incoming call area code and route index to be updated and the corresponding routing information are displayed together, the confirmation of the update content can be further facilitated. And it can be done reliably.
