The present invention relates to a method of operating a host exchanger and a remote exchange period in an exchange system in which a plurality of exchanges are connected and operated under the concept of a host exchanger (HOST) and a remote exchanger (RSM). The present invention relates to an operation method for enabling independent operation at a host exchange.

In the existing exchange system, which is connected to and operated by multiple exchanges with the concept of a host exchanger and a remote exchanger, the remote exchanger was subordinated to the host exchanger. That is, host switch and remote switch No. 7 Data communication through data link and Input Output Processor (hereinafter referred to as IOP) in charge of system operation are connected to host exchanger through T-BUS to communicate by inter-processor communication (IPC) method. In this case, the involvement of the host exchange was inevitable in the operation of each remote exchange. As a result, when the state of the host exchange is unstable, not only the operation of the remote exchange is made unstable, but also the load of the host exchange due to the operation of the remote exchange takes a lot.

Accordingly, an object of the present invention is to provide an operation method for allowing a host exchanger and a remote exchange to operate independently in an exchange system operated with a host exchanger and a remote exchange concept to solve the above problems.

The method according to the invention comprises a host exchange and a remote exchange period in a switching system having a host exchange operated by a message authorized through an input / output processor (IOP), and at least one remote exchange matched with the host exchange. The operating method may further include: a first transmission step of transmitting, by an operator, a system to be operated by an operator, an operating message (IPC message) including information about the selected system to a host exchanger; A first analysis step of analyzing the target system on which the operation message is operated by analyzing the host exchanger when the operation message is transmitted by the first transmission step; A second transmission step of transmitting an operation message to a corresponding remote exchange when the target system on which the operation message is to be operated is the remote switch 130; A result of the analysis in the first analysis step, when the target system on which the operation message is to be operated is the host exchanger, performing a function corresponding to the operation message in the host exchanger; A second analysis step of analyzing a target system of the transmitted message when a predetermined message is transmitted from the remote switch to the host switch; A third transmission step of transmitting the message directly to the I / O processor when the analysis result of the second analysis step is a target system of the transmitted message; As a result of the analysis in the second analysis step, when the target system of the transmitted message is the host exchange, it comprises the step of performing a function corresponding to the message transmitted in the host exchange.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an exchange system having a concept of a host exchanger and a remote exchanger for performing an operation method according to the present invention. The operator operates in accordance with a command authorized through an operator terminal 100 and an operator terminal 100. In accordance with the message transmitted from the input / output processor 110 (hereinafter referred to as an input output processor (IOP)) for sending an IPC message and outputting the message output from the exchange to the operator terminal 100, Host exchanger 120 operating the exchange, it is composed of a remote exchange 130 is connected to the host exchanger 120 operating.

In particular, the input / output processor 110 may receive an input data analysis unit 111 for receiving and analyzing data transmitted from the operator terminal 100, input data transmitted from the input data analysis unit 111, or a message data handler to be described later. IOP related function execution unit 112, IOP related function execution unit 112, and input data analysis unit 111 to perform functions to be processed in the input / output processor 110 for the message transmitted from the Message Data Handler, 114 The data transmitted from the message data handler 114, the message data handler 114, and the IOP related function performing unit 112 for handling the data transmitted from the IPC method and outputting the T-BUS by the operator terminal 100. It is composed of an output processing unit 113 for processing to be output through.

In addition, the host exchanger 120 communicates with the IOP 110 through the T-BUS to perform the main functions of the host exchanger 120, and the main processor (MP, 121) and the interprocessor processing with the main processor 121. By doing so, the remote switch 130 is of course composed of a line processor 122 for matching processing with subscribers directly accommodated in the host exchange.

The remote switch 130 is a command receiver 131 for receiving a command transmitted from the host switch 120 through the No. 7 data link, and performs a predetermined function for the command received at the command receiver 131. RSM related function execution unit 132, the result message output unit 133 for outputting the processing result message output from the RSM related function execution unit 132 to the host exchanger 120 through the No.7 data link. .

2 is a flow chart of the IOP 110 according to the operator command in the operating method according to the invention, Figure 3 is a flow chart of the host switch 120 in the operating method according to the present invention, Figure 4 is a flow chart of the present invention In the operation method according to the present invention, a flow chart of the input / output processor 110 for a message received by the host switch 120 is shown.

Next, a flowchart of a process according to the present exemplary embodiment shown in FIGS. 2 and 3 will be described in detail with reference to FIG. 1.

First, when key data is input through the operator terminal 100, it is transmitted to the IOP 110. When the key data is transmitted from the operator terminal 100, the IOP 110 applies the input data analyzer 111 to the input data analyzer 111. The input data analyzer 111 analyzes the content of the key data applied in step 201 of FIG. 2. If the analysis result, the key data for selecting the operating system, the flow proceeds to step 202 to the IOP-related function performing unit 112 outputs the key data analysis result to output information on the exchange that can be operated by the current IOP (110). Output

Accordingly, the IOP-related function performing unit 112 reads information on the operable exchanger stored in a memory (not shown) provided therein and transmits the information to the output processing unit 113. The output processor 113 processes and outputs the information on the operable exchange transmitted from the IOP related function performing unit 112 to be displayed on the operator terminal 100.

In operation 203, the operator authorizes a selection command for the operation target system through the information displayed on the operator terminal 100, and the authorized selection command is transmitted to the input data analyzer 111 for analysis. At this time, the IOP 110 is a memory (not shown) provided in the IOP-related function performing unit 112 and the ID and the sheet of each system for the remote switch 130 that is currently matched to the host switch 120 ( Site) information is stored. Therefore, when the target system to be operated by the operator is determined by the analysis of the input data analysis unit 111, the IOP related function performing unit 112 in the header area of the IPC message transmitted through the T-BUS for the selected target system The data is transmitted to the message data handler 114 so that the information can be carried and transmitted. Here, the information on the selected target system provided by the IOP related function performing unit 112 is information (address information) indicating which of a plurality of remote exchanges that are matched, whether it is a host exchange or a remote exchange.

The message data handler 114 transmits the IPC data including the information about the selected target system to the host exchanger 120 through the T-BUS.

However, the operation message (IPC data) transmitted together with the information on the selection target system as described above is formed by a command input after the selection process for the target system described above.

That is, when the determination result of step 201 is that the key data authorized from the operator terminal 100 is a command for operating the corresponding system, the process proceeds to step 204 and the input data analyzer 111 determines that the authorized command is IOP ( The analysis result is transmitted to the IOP-related function performing unit 112 so that it can be stored in a buffer (not shown) provided in 110. As a result of the determination in step 201, in the case of the command input completion key (for example, the ENTER key), the flow proceeds to step 205 to read the command stored in the above-described buffer (not shown), and proceeds to step 206. After the read command is formatted to be operated in the corresponding system, the process proceeds to step 207 to transmit the formatted message to the host exchanger 120 through the T bus.

When a command is transmitted from the IOP 110 via the T bus, the host switch 120 applies to the main processor 120.

When the message is received in step 301, the main processor 120 checks where the received message is received. Since the message is received from the IOP 110, the process proceeds from step 302 to step 303 to analyze what the target system is for the transmitted message. As a result of the analysis, the host switch 120 proceeds from step 304 to step 305 to process a function corresponding to the received message.

However, in the case of the remote switch 130, the process proceeds from step 304 to step 306 so that the message is transmitted to the data link of the corresponding remote switch 130 through the line processor 122.

When a predetermined message is transmitted from the host switch 120 through the NO.7 data link, the remote switch 130 receives the received message through the command receiver 131 and transmits the message through the RSM related function performer 132. Run the routine that corresponds to When the processing for the routine is completed, the result message is transmitted to the result message output unit 133. The result message output unit 133 outputs the result message authorized from the RSM related function performing unit 132 to the host exchanger 120 through the NO.7 data link.

The host switch 120 transmits the message to the main processor 121 through the line processor 122 when the message is received from the remote switch 130. The main processor 121 checks the source source that provided the message received in step 302. At this time, since the transmitted message is transmitted from the remote switch 130, the main processor 121 proceeds from step 302 to step 307 to determine whether the target system of the transmitted message is the IOP 110 or the host switch 120. Check it.

As a result of the check, if the message is transmitted to the IOP 110, the process proceeds from step 307 to step 308 and immediately bypasses (by-pass) and transmits to the IOP 110 through the T bus. However, if the message is transmitted to the host switch 110, the process proceeds from step 307 to step 310 and the main processor 121 performs a function corresponding to the transmitted message.

If the message is received from the host exchanger 120 in step 401 of FIG. 4, the IOP 110 proceeds to step 402 to identify a system that has transmitted the message from the message header information. The identification of the transmission system based on the header information is performed by the IOP related function performing unit 112. The process proceeds to step 403 and processes corresponding to the message received for each transmission system based on the identified information. That is, when the data is output to the operator terminal 100, the output processing unit 113 is controlled to format and output the output message using the information of the message transmission system, and when the charging data is received, the file of the corresponding transmission system is stored. The billing data received by access is stored, and in the case of a system data backup request, the system data is backed up by accessing the directory corresponding to the system that sent the message.

As described above, the present invention provides a method of directly operating a remote switch with an IOP matched to the host switch using a data link of the host switch and the remote switch period, thereby independently of the remote switch. In addition, the independent operation can reduce the load of the host switch according to the operation of the previous remote switch, and if there is no problem in the data link, the remote switch can be operated even if the operation state of the host switch is unstable. There is no effect on the operation of the system.
