Description

Method for searching a command of a exchange}

The present invention relates to a wired switch, and in particular, when a user inputs various commands necessary for operating a small capacity wired switch, such as an operator terminal, a wired line which enables a user to quickly retrieve detailed information on a plurality of MMC commands and various parameters. It relates to a command search method for the operation of the exchange.

All exchanges are physically connected by using relay lines to other networks or other stations to provide call processing between subscribers located in their own country and other networks or stations located in other countries, and provide maintenance functions for such relay lines. The same applies to pre-exchangers.

In general, a method for transmitting a signal for controlling a call service between exchanges includes individual channel signaling (CAS) and common channel signaling (CCS). Individual signaling means that the signal related to each call is transmitted through the call line as in the Loop Decadic or R2 signal. This means that the signal is transmitted to the call through the signal line. All exchanges use one of the above R2 or No.7 signaling schemes to exchange information with other stations in order to provide call services between their own subscribers and subscribers of other countries.

In most exchanges, as one of maintenance functions, relay signals transmitted and received between other stations and local exchanges according to the signaling method used for the inter-station relay call generated by the operator by occupying a specific relay call resource designated by the host's operator at the time of request and registration. There is a function that prints out detailed information about them.

Hereinafter, with reference to the accompanying drawings for a general small capacity wired switch will be described.

FIG. 1 is a schematic block diagram of a typical small-capacity wireline exchange. The small-capacity exchanger performs a centralized call processing function with a telephony control subsystem (TCS) 50, which is a subsystem for performing distributed call processing. It consists of an Interconnection Network Subsystem (INS) 60, which is a subsystem, and a Central Control Subsystem (CCS) 70, a subsystem that performs centralized operation and maintenance functions.

Each TCS 50 has a Telephony Control Processor (TCP) 51 which is a control unit for call flow control, statistical measurement, collection and reporting, billing measurement and reporting.

The CCS 70 is an OMP (Operation and Maintenance Processor) 71 which is a control unit for overall system maintenance, network management, billing, statistics, and database management, and a Human Machine which is a control unit for operator terminal management. Processor 72).

All the commands necessary for the operation of such a small wired switch are composed of verb-noun1-noun2: [para1, para2, ....], where each parameter type is different according to the command. To do this, you need to know the exact type and value of each parameter of the command. However, it is very difficult to know all about all 1500 commands, so the operator has a separate instruction booklet next to the operating terminal for reference.

Let's take a look at the existing search commands for searching for MMC (Man Machine Command).

The command simply retrieves and outputs the MMC command that contains the input parameter and the information of what parameter is used.The detailed information related to the parameter, that is, what value is required as a parameter of what meaning, ENUM list type, etc. In the case of parameters, since the corresponding information cannot be obtained, there is an inconvenience in that related parameter information must be found again using a separate booklet for inputting a command.

Accordingly, an object of the present invention is to solve the problems according to the prior art described above, and an object of the present invention is to input a plurality of MMC commands and various parameters when inputting various commands necessary for the operation of a small-capacity wireline switch to an operator terminal. The present invention provides a method for searching a command for the operation of a wired switch so that a detailed information on the information can be retrieved more quickly.

A feature of the present invention for achieving the above object is to receive the command number (CRN: Command Request Number) or command to search from the operator terminal to pass the corresponding parameter to the MC block mounted in the HMP in the CCS system After receiving this, HMP block searches command-related data previously stored in HMP hard disk and HMP database received from OMP through Hash. It is in the output terminal to the operator terminal through the OC block.

In addition, another feature of the present invention describes a specification for commands to be exchanged with an MMS and a higher level application program in an IMD (Input Message Description) file related to an input command, in which one IMD file exists. The information of various parameters related to this file command is entered. In addition, the search for parameters related to the command is performed using the information of the IMD, and the search for each information uses a hash in consideration of the search speed.

That is, the command retrieval method for the operation of the wired switch according to the present invention is characterized in that, in the command retrieval method for the operation of the wired switch using a database that stores the operator terminal, various detailed information related to the command, Determining whether the first character of the input parameter is a number or a character, when a command for requesting command information output from the operator terminal and various parameters are input; If the first parameter is a number, recognizing the corresponding parameter as a CRN, and searching the database containing the command information using the same parameter to determine whether the corresponding command exists; If the command exists, obtaining a command using a hash table, and then outputting the command to the operator terminal; If it is determined whether the searched command includes a parameter, and if the parameter includes a parameter, a step of repeatedly searching for the parameter information by the number of parameters using a hash table and outputting all the retrieved parameter information to the operator terminal. have.

In still another aspect of the present invention, if the first letter of the input parameter is not a number, searching for a command using the corresponding parameter according to the number of parameters; Determining whether a header information pointer of a corresponding instruction is null; As a result of the determination, when the header information pointer of the corresponding command is not null, the step of outputting the command information obtained by obtaining the command information using the hash table to the operator terminal and searching for the next command is added.

Hereinafter, a command search method for operating a wired switch according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a view schematically showing a small capacity wired switch applied to a command retrieval method for the operation of a wired switch according to the present invention. FIG. 2 is an OMP for driving HMP and HMP in a CCS of the small capacity wired switch system. It shows the relevant database.

Referring to the operation of FIG. 2 briefly, if a command for requesting the output of the command information is input in the command analysis process performed in the MC block (not shown) in the HMP 72, the search function is performed using the input parameter information. Then, the search information requested by the OC block is again output to the operator terminal 80 through the MC block.

That is, when an input requesting the command information output from the operator terminal 80 is generated, the operation is started, and the operator inputs a command of DIS-CMD-INFO: para1, para2, para3 :. First of all, the first parameter is examined and the method is different if the value is a number or a character. First, if the first parameter is a character, it performs the same function as the existing service CMD command. Search for a command that includes the command to output the information of the relevant command to the operator terminal (80).

Next, when the parameter value is a number, the corresponding parameter is recognized as CRN, which can be referred to as a unique number of the IMD that each command has. It searches the database in the HMP containing the command information to determine the existence of the command, and if there is no command, outputs a message indicating that the command does not exist and exits. In case of doing so, information of each instruction is obtained.

After that, the command information is output and if the searched command includes a parameter, the information of the parameter is searched again, where the information of the parameter is the name and type of the parameter, that is, whether the parameter is a number. Information about whether it is a character string, direct number, direct number, longon, short, short, enum list, year, month, time, etc. and the default, maximum and minimum values of the parameter, and the parameter is an ENUM list. In the case of each list information. In fact, the information required by the operator.

By repeating the number of parameters to retrieve the information of the parameter, and outputs the information to the operator terminal 80 to respond.

This operation will be described in detail with reference to FIGS. 3A to 3C.

3A to 3C are flowcharts illustrating operations of a command search method for operating a wired switch according to the present invention.

First, when the operator inputs a command for requesting command information output through the operator terminal 80, that is, a command of DIS-CMD-INFO: para1, para2, para3 :, the first parameter for the input command is a character or not. It is determined whether the number (S101).

As a result of the determination, when the first parameter is a number, it is searched whether the corresponding command exists in the database of the HMP 72 (S102).

As a result of the search, if the command does not exist in the database, an error information message indicating that the command does not exist is output to the operator terminal 80 (S103), and if the command exists in the database, the hash table is used. After obtaining the command information (S104), and outputs the obtained command to the operator terminal (80) (S105).

Subsequently, it is determined whether the number of parameters is '0' (S106). If the number of parameters is not '0', other related information is output. When the number of parameters is '0', parameter information is obtained by using a hash table. After that (S108), the corresponding parameter information is output (S109).

The operation is repeatedly performed until all parameters are output (S110).

On the other hand, it is determined whether the number of parameters of the command input in step S101 is '1' (S111), and if the result is determined that the number of parameters is '1', the command is searched using the corresponding parameter. Search for the command (S112).

Subsequently, it is determined whether the header information pointer of the searched instruction is empty (S113). If the header information pointer is empty, the search is terminated. If not, the instruction information is obtained using a hash table (S114). ).

Subsequently, after outputting the acquired command information to the operator terminal 80 (S115), the next command is searched (S116).

When the number of parameters is not 1 in step S111, it is determined whether the number of parameters is '2' (S117). As a result of the determination, when the number of parameters is '2', Similarly, the command search operation is performed. That is, the command is searched using the corresponding parameter, that is, the command is searched using the hash (S118).

Subsequently, it is determined whether the header information pointer of the searched instruction is empty (S119). If the header information pointer is empty, the search is terminated. If not, the instruction information is obtained using a hash table (S120). ).

Subsequently, after outputting the obtained command information to the operator terminal 80 (S121), the next command is searched for (S122).

In addition, when the number of parameters is not 2 in step S117, it is determined whether the number of parameters is '3' (S123). As a result of the determination, when the number of parameters is '3', the number of parameters is '1, 2'. Command search operation is performed as in '. That is, the command is searched using the corresponding parameter. That is, the command is searched using the hash (S124).

Subsequently, it is determined whether the header information pointer of the searched instruction is empty (S125). If the header information pointer is empty, the search is terminated. If not, the instruction information is obtained using a hash table (S126). ).

Subsequently, after outputting the obtained command information to the operator terminal 80 (S127), the next command is searched (S128).

As described above, the command search method for the operation of the wired switch according to the present invention is operated by using a separate command-related information booklet for solving a problem that the operator is difficult to use all the information of the relevant parameters of the command. It is possible to search the detailed information such as the parameter information of the command by using the existing database instead of simply searching the command on the operation terminal, providing the operator with the convenience of operating the exchange system. There is a shortening effect, and even an operator with little experience in operating the system can operate the system conveniently and quickly by using the command information search function.
