Description

  The present invention relates to a communication line search technique, and more particularly, to a line search system that can grasp a line that is affected when a line is maintained or transferred and can efficiently switch to an alternative line or calculate a downtime. .

  Conventionally, when a communication line is disconnected due to relocation of a telephone pole due to road construction, etc. (this is called trouble transfer), the affected line is identified from the line configuration diagram and the name of the line In advance, it was necessary to obtain permission to stop the communication line from the user (this is called borrowing the line).

  By the way, even if the circuit configuration diagram is created, the circuit design system for creating the configuration diagram is different for each communication system (communication type) such as ATM, ISDN, FR, VLAN, and WDM. A line is provided to the user via a plurality of communication systems.

  As a conventional line search method, the work side submits a communication work request form describing the desired date and time, reason, etc. for the path and line to be disconnected, and confirms that there is no work congestion in the work status management system. To decide whether to borrow or not.

Hereinafter, a conventional line search method will be described with reference to FIG.
First, in the individual work request process, a communication work request is issued at a construction charge location (S201). The request form includes information such as work contents, stop line, and stop date / time. Next, in the work adjustment process, the line operation team receives this request, inputs it into the line management system (INMS), searches for the stopped line (S202), and collates with the user information system that stores the borrowed conditions. (S203). If the conditions are not met, a consultation is performed. On the other hand, if the condition is OK, it is input to the work status management system to check the work congestion (S204), and if there is work congestion, a consultation is performed. On the other hand, when there is no congestion of work, next, as a borrowing adjustment step, a line borrowing request and a construction report are created and borrowing adjustment is performed (S205). In this adjustment, if the borrowing is NG, consultation will be conducted. At this time, if necessary, discussions are also made including other departments such as the service coordination team and the linking other business operators, and if the borrowing is OK, the decision of the communication work request (borrowing decision) is input to the INMS (S206). ), And send the decision to the person in charge of construction and a copy to the control commander of the operations team.

  If the work adjustment process includes a lot of lines such as VLAN and WDM, check the contents of the path, section, line, etc. by the person in charge of the work, and check that the work side request is correct by INMS I was checking for leaks.

  In the above conventional method, since the user is determined from the line name or the like, the place depends on the individual skill, and a mistake may occur. There is also a problem that it takes time and effort to adjust the stoppable time with the user.

  On the other hand, Patent Document 1 discloses a management technique for renting an empty line among dedicated lines of a communication network to another communication network or borrowing an empty line among dedicated lines of another communication network. Is described. Specifically, a first use request signal for requesting the use of a free line is transmitted, and a first response signal indicating whether or not the corresponding free line is used is transmitted. If the first response signal is a use permission signal, a second use request signal for requesting use time or the like is transmitted, and a second response signal indicating whether or not the corresponding free line is used is transmitted and received. An empty line is used in response to the second response signal.

However, since the technique of Patent Document 1 is not intended for borrowing (stop permission) at the time of line construction, the above-described problem still remains with respect to management of borrowing destinations across a plurality of communication systems.
JP-A-6-70025

  As described above, according to the conventional technology, when there are a plurality of communication systems, it is necessary to determine the user from the line name of the system that is independently managed and operated. There was a possibility of human error such as mistakes and leaked lines. In addition, it is necessary to check the user's stoppable time with another system.

  The present invention has been made in view of the above-mentioned circumstances, and by constructing an efficient database and automating the search for a borrowed line, it is possible to prevent human error and perform a quick and leak-free search. An object of the present invention is to provide a line search system.

  In order to solve the above problems, the present invention provides a data structure in which the line design system is unified, the borrowed acquisition destination determined by the line name or the like is added as a separate item, and items such as stoppable time are added. did.

Specifically, the line search system according to the present invention is provided for each communication type, and includes a line management table for storing each line and user information in association with each other, and a connection between a communication base station or a relay station.

And means for extracting path information and extracting user information corresponding to the path information of the line management table based on the communication type and the base station information included in the path information. .
In the present invention, the labor saving at the time of borrowing is achieved by automatically executing the borrowing request to the user.

In the line search system according to the present invention, the result of the inquiry by the inquiry means is stored, and for the line of the user who cannot be borrowed, it is determined whether or not communication by another path of the path information is possible. And an alternative line changing means for changing to the other path.
In the present invention, it is possible to change to an alternative line by managing a branch point of a path.

  In addition, the line search method according to the present invention is provided for each communication type, and for each section that is a connection between communication base stations or relay stations, the section and path information including the communication type and base station information are obtained. A line search method for searching for a borrowed line using a management server having a section / path correspondence table to be stored in association and a line search server having a line management table to store each line and user information in association with each other. Based on the input section information, the management server is accessed, the section / path correspondence table is referred to, path information is extracted, and the communication type and base station information included in the path information are extracted. Step of accessing the server for line search based on the above and extracting user information corresponding to the path information of the line management table stored in the server , A step of transmitting a line borrowing request to the user terminal based on the user information, and storing the result of the request, and for the line of the user who cannot be borrowed, determining whether or not communication by another path of the path information is possible, A step of changing to another path when communication is possible.

  In the present invention, section information and path information are managed by a server for each communication type, and information such as a base station included in the path information is used as an index, and line information in the line management table of the line search server. , Search for the corresponding user, and make a borrowing request.

  Further, the central processing unit 12 is a transmission / reception processing means (function) 41 that exchanges data with the transmission / reception unit 11, and an input / output processing means that exchanges data with the input unit 13 and the display unit 14 ( Function) 42, user information registration means (function) 43 for registering information such as the user name and inquiry destination, line information registration means (function) 44 for registering information such as the configuration of the communication line, and the communication line configuration to the line Line name generating means (function) 45 for automatically generating names, section information registering means (function) 46 for registering section information, borrowing request receiving means (function) 47 for receiving borrowing requests for communication lines, and at the time of borrowing request User information extraction means (function) 48 for extracting user information from input information, inquiry means (function) 49 for inquiring the user whether borrowing is possible, and notifying the borrowing request destination of the inquiry result And a query result notification unit (function) 50.

  Each means 41-50 is realizable as a computer function executed by software.

  The storage unit 15 includes a user information database (DB) 61, a line management table 63, and a section / path correspondence table 62 provided for each communication type.

  The section / path correspondence table 62 may be provided on the terminal device 20 side.

<Section, path description>
Next, a method for managing communication lines with section information and path information will be described with reference to FIG.

  In this figure, the ATM switch (start) of the head office of the company A and the ATM switch (end) of the sales office 4 of the company A are connected via a communication line. Here, the head office (station identification symbol Z07) and the sales office 4 (station identification symbol Z16) denoted by reference numeral 6 in FIG. 2 are terminal stations (starting and ending points) that provide a line to the user. Other stations (station identification symbols A00, A01, D01,...) Are referred to as “relay stations”.

  In the figure, numbers 1 to 5 in the section / path list represent section information, and number 6 represents path information. By storing the relationship between the section and the path, it is possible to know which section is used for communication. This number corresponds to the number on the line screen, and number 6 is a path based on the names of the two base stations and the communication type provided to the user (in this example, the identification symbol VC-4L 1 for ATM communication). The numbers 1 to 5 are specified by the names and communication types of two opposing stations. In the station list, the correspondence between station identification symbols and station names is displayed.

  That is, the station Z07 connected to the ATM exchange (start) is connected to the station A00 by the communication system F-600M, and further branches to the station A00 (device number S2003) and the station A10 (F1002) by the path SW at the station A01. Is done. Station A00 is connected to station C01 (A2006) via section 5. This section 5 represents F-2.4G.

  The connection relationship between stations as displayed on the line screen is stored in the section / path correspondence table 62.

  The section information may be managed by regarding stations having the same communication type (WDM, FR,...) As one section.

  In this way, connections between relay stations are managed by section information, and connections between base stations that provide a line to a user are managed by path information.

<Line information registration>
A method of managing the user's line information will be described using the management screen shown in FIG.
As shown in this figure, a line number and a line name are assigned to each line provided to the user (customer) and stored.

  Prior to the registration of the line information, first, as user information, in addition to the user name and contact information at the time of failure, information such as the department name in charge, the name of the person in charge, the telephone number, and the mail address are input as the contact information at the time of borrowing. This user information is stored in the user information DB 61 via the user information registration means 43. Note that the method for registering user information is not limited to this. User information such as a user name is registered in advance on a separate screen, and the user name or user number is designated and input, so that the information is displayed. It may be displayed. As for the contact information at the time of borrowing, it is possible to register / change on the management screen for each line as shown in FIG. It is preferable to leave.

  The operator designates a base station for each line as line information. In the example of FIG. 3, the company A head office is designated as the starting point and the company A sales office 1 is designated as the end point as the two base stations. At this time, a DB for storing station information may be provided separately, and the address and telephone number of the station may be displayed with reference to this DB. The operator further registers necessary information such as the opening date.

  In addition, as communication line information, information such as communication type and communication speed provided to the user such as FR and ATM is also set.

<Line name generation processing>
When information such as the base station, communication type, and communication speed as necessary is input, the line name generation unit 45 is activated, and a line name is created and stored in the line management table 63.

  FIG. 4 is an explanatory diagram of the data configuration of the line management table 63. In this figure, information such as line name, borrowed contact information, and user number is stored in association with each line number.

  The user number corresponds to the user number in the user information DB 61, and user information can be extracted using this as an index.

  Then, as the line information, information such as the type of communication provided to the user, the starting and ending stations (offices), and the address are input.

  The line management table 63 stores information effective for identifying a line such as a starting point name, an ending point name, a communication type, and a communication speed constituting the line name.

<Section path information setting process>
Section information and path information are set for each facing of each relay station. This setting is performed by accessing the borrowed line search system 1 via the terminal device 20 installed in each station.

  The setting information input via the terminal device 20 is received by the transmission / reception unit 11 of the borrowed line search system 1 via the communication network 40 and written to the section / path correspondence table 62 by the section information registration means 46. .

  Next, how to register section information and path information will be described with reference to FIG. FIG. 5 is a configuration example of a section / path correspondence table of WDM communication between the A station and the B station.

  For example, CH5 indicates that an F-2.4G SYS2 line is accommodated between the A station and the S station as a section. Also, in this communication line, as the path information, ATM communication (VC-4L 1) of the H station-A station branch of the base station A company, ATM communication (VC-32L 7-12) between the S station and the A station, etc. It shows that four types of paths are multiplexed and accommodated.

  The accommodation path may be selected from line names stored in advance in the borrowed line search system 1. In this case, it is preferable to add necessary information on the site side in addition to the selected line name.

This way, the department that manages the section manages the information independently,
At the time of construction, the borrowed line information can be extracted from the path name by the borrowed line search system 1.

<Line borrowing processing>
With reference to the flowchart of FIG. 6, the processing of the borrowing request reception means 47 when the user's line is stopped due to the transfer of a certain communication facility or maintenance work in the table configurations 62 and 63 described above.

  For example, in FIG. 7, it is assumed that the WDM communication equipment between the A station and the B station indicated by a dotted line x is stopped due to relocation. At this time, the section / path correspondence table 62 shown in FIG. 5 is accessed (S001), and the path information corresponding to the section is extracted based on the accommodated section information of CH1-9 between the stations (S002). Then, the path information is input on the screen of the terminal device 20. This path information is a path name having a start point, an end point, a communication type, and the like. If there are a plurality of identical paths, the path information is managed so as to be unique for each communication speed, for example.

  Next, a starting point name, an ending point name, a communication type, and a communication speed are extracted from the path name (S003), and a contact information for borrowing is extracted with reference to the line management table 63 (S004).

  The extracted borrower is inquired of whether or not to borrow (S005). After a predetermined period (S006), if there is an answer, the answer is saved (S008). If the answer is “permitted” (“YES” in S009), it is determined whether or not there are other paths corresponding to the section. Similarly, the processing after step S003 is repeated (S010). If the borrowing inquiry is completed for all paths corresponding to the extracted sections (“YES” in step S010), the process returns to step S002 and the same processing is repeated for all accommodation sections (S011).

  On the other hand, if there is no answer in step S007, if the inquiry result is not “permitted” in step S009, it is determined whether or not to make an inquiry at another time (S013). If “YES”, The time is designated and the inquiry is performed again (S014).

  As described above, the result of the inquiry by the borrowing request process is stored for each user of the line management table 63 and is displayed, for example, in the remarks column of the screen of FIG.

  In the above-described processing in step S005, the person in charge of the inquiry about whether or not the loan can be used may be confirmed by telephone or the like. However, if it is automatically performed by the system, the inquiry state is displayed in the corresponding user column of the line management table 63. The inquiry request means 49 sends a borrowing request to the user terminal 30 by e-mail or the like. At the same time, the inquiry state is converted to “inquiry”.

  When the borrowing permission is returned from the user terminal 30, the inquiry state is set to "borrowing permission". At this time, the user may be allowed to set a borrowable period. Alternatively, borrowing cannot be permitted for the entire borrowing period inquired by the user, but if it is possible for a part of the period, the period may be set to allow borrowing. Good.

  When a predetermined period has elapsed after obtaining answers from all target users or inquiring whether or not to borrow, the inquiry result notifying means 50 transmits the result to the terminal device 20 of the borrowing request source.

  As described above, according to the present embodiment, a table 62 having section information and path information is provided for each communication type, and a table 63 having path information or line information and borrowed user information is provided separately. Since the user is specified by using the path information as an index based on the section to be stopped, the line borrowing permission can be obtained smoothly.

Next, the second embodiment will be described focusing on the case with the first embodiment.
The configuration of this embodiment is shown in FIG. The main difference from FIG. 1 is that a management server 70 is provided for each communication type, and the borrowed line search system 1 is connected via a LAN 80. Further, the section / path correspondence table 62 is stored on the management server 70 side, and as a function of the borrowed line search system 1, an alternative line search means 51 is provided in the central processing unit. Since section / path information is managed by the management server 70, the section information registration means 46 in FIG. 1 functions as each management server 70.

  In the above configuration, when a communication line is stopped, the management server 70 for each communication type refers to the section / path correspondence table 62 and uses the borrowed line search system 1 to borrow the request based on the path information. do.

In the borrowed line search system 1, when the borrowing request receiving means 47 receives the request information, the user information extracting means 48 extracts the borrowed contact information using the base point name, communication type, etc. in the path information as an index. The inquiry process is executed by the same process as that of the first embodiment.
As a result of the inquiry processing, if the permission for borrowing is not obtained, the alternative line search means 51 is activated.

Hereinafter, the processing of the alternative line search means 51 will be described with reference to FIG.
When activated, the alternative line search means 51 searches the line management table 63 to check whether there is a free line having the same communication type at the start point, the end point, and the end, and having a communication speed faster than the line used by the user. (S102), and if it exists, the alternative line name is written in the line management table 63 (S103). If a candidate for a free line is detected in step S102, it is necessary to confirm that the line is not subject to borrowing. For this purpose, it is preferable to write the status of the section to the line management table 63 at any time, such as when it is borrowed.

  On the other hand, if a free line that satisfies the condition cannot be detected in step S102, “no alternative line” is output to the line column of the user in the line management table 63 (S104).

  On the management server 70 side of the vacant line, a temporary use flag is set for the vacant line. At the same time, a temporary use flag is set in the line management table 63 and a borrowable code is set. When the borrowable codes of all users of the lines associated with all the paths of the communication equipment to be transferred are set, the construction permission is output to the requesting management server 70 through the inquiry result notifying means 50. .

  According to the present embodiment, since the unused line and the period are allocated to the empty line by another path, the borrowing adjustment can be performed with the minimum necessary allocation change.

  The present invention is not limited to the above-described embodiment, and can be implemented with various modifications. For example, instead of the LAN 80 shown in FIG.

  The alternative line search means 51 is not executed when permission is not obtained after the inquiry, but is started before the inquiry means 49 is executed, and the inquiry is executed when there is no alternative line. You may make it do.

  The above technique can be used for maintenance work of communication facilities.
