It consists of (23).

Further, reference numeral 30 denotes an IF processing stage for processing a transmission / reception intermediate frequency (IF) signal in a 70 MHz band, and the IF processing stage 30 receives an intermediate frequency (IF) signal applied from the RF receiver 22. Intermediate frequency combination / distribution unit for separating and outputting a plurality of intermediate frequency signals and outputting a combination of intermediate frequency signals applied from a single channel per carrier (SCP) channel unit (SCU) 33 to be described later. C / D) 31 and the first SCPC channel unit for demodulating, decoding and outputting the IF signal applied from the intermediate frequency combination / distributor 31 and the message output from the network controller 40 to be described later. It consists of a second SCPC channel unit 33 which is encoded, modulated and output.

Further, reference numeral 40 performs a polling function for checking the state of each base station based on a response message transmitted from the base station after transmitting a control message to each base station through the SCPC channel unit 33, and a specific base station If there is a call request from the base station, the base station determines whether the other base station is in a communication state based on the information obtained in the polling process, and if the communication state is available, allocates available traffic channels of the satellite to both base stations. This is a network control unit that performs system control such as allowing direct communication with each other.

On the other hand, the network controller 40 extracts packet information from a message applied from the processor 41 and the SCPC channel unit 32, which controls the entire system and in particular, the call processing between the base stations. In addition, a service channel controller (SCC) 42 for generating and outputting a message of a time division multiplex (TDM) stream to the SCPC channel unit 33 and a service with the processor 41. Dual port RAM 43 for data transmission and reception between the channel controller 42, the program storage unit 44 in which the operation program of the processor 41 is stored, and the status information of each base station obtained by the above-described polling operation The base station information storage unit 45 is stored, and the channel information storage unit 46 stores the usage state of the communication channel.

In addition, reference numeral 50 denotes a network management system that enables the satellite communication network operation manager to monitor the overall network operating status and to control the entire satellite system including the base station as necessary.

That is, in the conventional satellite system having the above-described configuration, when there is a call setup request from any subscriber base station (not shown), the base station information obtained by polling by the processor 41 inside the network control unit 40 is polled. And allocating a channel having a requested bandwidth among currently available communication channels based on the channel state information recorded in the channel information storage unit 46, and a network operation manager through the network management system 50. While communicating with the processor 41 of the control unit 40, it is possible to control the overall system including the base station by monitoring the overall operating status of the system or by inputting a predetermined command as necessary.

On the other hand, among the commands that the network operation manager processes through the network management system 50 includes commands related to updating existing system information or new registration and deletion, that is, a system change command (hereinafter, referred to as a UPD command). If these instructions are executed, the processor 41 in the network controller 40 needs to download the changed system information to the operator terminal side of the network management system 50 every time the instruction execution is completed. If the command is processed, the processing speed is slowed and the load on the system is inevitably increased.

When operating the system, for example, several UPD commands are sequentially processed, such as a new subscriber registration process, and a task of finally executing one completed operation is repeated. Based on this, the UPD commands are grouped and batch processed. This reduces the load on the system and shortens the time it takes to process consecutive commands.

The present invention was created in view of the above circumstances, and the operator can reduce the download execution time according to the system information change by processing the system change command input by the operator together by grouping related commands to be processed together. The purpose is to provide a satellite communication network management system with processing functions for each input command group.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

FIG. 2 is a block diagram showing an internal configuration of a satellite communication network management system equipped with a processing function for each operator input command group according to an embodiment of the present invention. In FIG. 2, reference numeral 51 denotes an entire system including a base station in which a network manager includes a base station. Operator terminal for inputting data required for control and management and monitoring the network operating status, 52 is a contract with the main processor 41 in the network control unit 40 in accordance with the command input through the operator terminal The processor 52 is a processor that controls the entire system while communicating through the established protocol. Although not shown, the processor 52 is duplicated in the same configuration so as to alternate roles in preparation for any abnormal operation.

On the other hand, reference numeral 53 is a command storage unit for storing the various commands used in the satellite communication network management system 500 as data, 54 is the operator terminal 51 based on the data stored in the command storage unit 53 An input command checking unit 55 for checking whether or not an error of an input command is executed by performing a syntax check and semantic check on the command inputted through the command, wherein the processor 52 and the network controller 40 It is a terminal server having a redundant structure that provides a communication line between the main processors 41.

In addition, reference numeral 56 is a hard disk drive (HDD) that has a redundant structure like the processor 52 and stores data for communication network operation and system management, and 57 is a channel used for subscribers communicating through a satellite channel. It is a magnetic tape drive (MTD) that stores billing data such as TC (Trunk Code) data and talk time of calling / receiving subscribers.

Is a timer that counts a predetermined time according to the control of the UPD command management unit to be described later, and 61 determines whether the command inputted through the operator terminal 51 is a UPD command and based on the timer 60. UPD command management unit that executes the batch processing function for UPD commands that are continuously input by controlling the operation.

Next, the operation of the device having the above configuration will be described.

The satellite communication network operation manager monitors the system status including the satellite channel and each base station currently operating through the operator terminal 51 of the network management system 50 and, if necessary, inputs data for system control through contracted commands. When the command is input by the operator, the processor 52 first controls the input command checker 54 to parse and semantic check the command input by the operator. By executing the command, you can check whether the command entered is in error.

If an error is detected, such as an error check result, the command input by the operator is confirmed as an unusable command in the system, the processor 52 transmits an error message to the operator terminal 51. If not, the full text of the corresponding input command is output to the UPD command managing unit 61.

On the other hand, the UPD command registered in the management target command storage unit 58 is the first command inputted in a work process to be grouped and processed, for example, CRTE (create), add (ADD), delete (DEL) ; delete), change (CHAG; change), and cancel (CANL; cancel) commands related to system changes, such that the UPD command manager 61 stores an operator input command authorized from the processor 52 for the management target command. On the basis of whether the instruction is registered in the section 58, it is determined whether the instruction is grouped and should be processed in a batch.

As a result of the determination, when it is determined that the operator input command is not a command to be processed in batch, the UPD command management unit 61 returns the entire command to the processor 52 together with the determination result signal. The command returned from the UPD command manager 61 is transmitted to the network controller 40 through the terminal server 55 to execute the command.

On the other hand, if the operator input command is determined to be a batch processing target command, the UPD command manager 61 inputs the command as the next order within a predetermined time (for example, about 5 seconds) set by setting the timer 60. If it is determined that the next sequence of commands is input as scheduled within the time limit counted by the timer 60, the UPD command manager 61 resets the timer 60 to resume counting operation. If the next sequence of instructions registered in the storage unit 59 for each UPD instruction group is not input while the timer 60 counts the predetermined time limit, the instruction is input until the present time. By outputting the UPD instruction in the execution standby state to the processor 52, the instruction, which has been waiting for execution, is transmitted to the network controller 40 to be sequentially processed. It is air.

On the other hand, when it is confirmed that all of the grouped commands are input through the above-described process, the UPD command manager 61 transmits sequentially to the processor 52 from the first command to be processed, the processor 52 groups them together and transmits them collectively to the network control unit 40 through the terminal server 55 to execute the corresponding commands collectively.

As a result, the update information downloaded from the network controller 40 is also received in a batch, and as a result, the processing speed of the corresponding command is faster.

In other words, according to the above embodiment, the system-input command input by the operator is processed together by grouping related commands to be processed in a batch, thereby reducing the download execution time according to the system information change. It is possible to realize the satellite communication network management system.

Meanwhile, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.

As described above, according to the present invention, by grouping UPD-related instructions to be batch processed together, the download execution time according to system information change can be shortened and the load on the system can be reduced.
