The present invention relates to a multi-path simultaneous setting method and an inter-device path setting control method of a microwave radio communication system in which the entire system is configured.

  A path management system exists in a network (wired system) of wired devices typified by optical devices. As an example of a path management system, Patent Document 1 discloses a method of setting a path that connects nodes of an information transmission system such as an optical submarine cable system, using a screen of a display of a worker terminal device. . This path setting method is intended for a network system including a plurality of ring networks including a plurality of nodes connected in a ring shape to each other via a communication line on which a plurality of paths are multiplexed, for example.

  According to this, the screen of the operator terminal device display unit is divided into a plurality of areas in association with the section between each node in the ring network to which the node to which the device is connected belongs, and the path existing in that section The arrows respectively associated with are displayed in the divided areas. Then, specify the low-speed channel of the node that is the starting point of the path to be set, specify the low-speed channel of the node that is the end point of the path to be set, and set it in the display area corresponding to the specified node section. Displays an arrow associated with the power path. Further, when there is another path to be set, the above process is repeated, and a path setting request corresponding to the arrow associated with the path to be set is sent to the node related to the path formation. The node that has received the path setting request forms a new path based on the request. By doing so, the path setting method of Patent Document 1 is said to be able to improve the human-machine interface and improve operational convenience.

  On the other hand, in recent network management, SNMP (Simple Network Management Protocol) is used as a protocol that defines a communication method of information for monitoring and controlling network equipment (NE: Network Equipment) on an IP (Internet Protocol) network. Is the mainstream. SNMP is a protocol corresponding to the application layer of the OSI (Open Systems Interconnection) reference model, and uses UDP (User Datagram Protocol) for the lower transport layer.

  In SNMP, a device on the management target side is called an SNMP agent (may be further subdivided into two types, “master agent” and “subagent”), and the device managing the SNMP agent is called an SNMP manager ( Or “network management station (NMS)”. Management information used in SNMP is stored in a table (database) called MIB (Management Information Base). Information in the MIB is composed of object variables (MIB variables) identified by object IDs (identifiers).

The SNMP manager side sends Get information (Get message) to the SNMP agent side, requests information in the MIB specified by the object ID, receives a response, and sends Set information (Set) to the SNMP agent side. Message) to request the setting change of information in the MIB specified by the object ID, receive a response as a result of the execution, or change the state of information in the MIB in advance (event occurrence). Network management is performed by receiving a notification (trap notification) called “trap” sent from the agent side.

On the other hand, if it is desired to change the CH number in the CH setting result screen M4 before this control, the CH setting of each wireless device 10 can be changed (assignable CH) by pressing the “change setting CH” button. It is possible. When the “OK” button is pressed after changing the CH setting, the control terminal 22 causes the SNMP communication processing unit 113 to control the starting point No. via the interface unit 112 under the control of the control unit 104. The path setting information corresponding to the changed CH setting result is transmitted as “SNMP Set” control information to the first radio apparatus 10, and thereby path setting control by the radio apparatus 10 is executed.

  13 is the same as that described in FIG. 1 to No. 1 from the wireless device 10. The screen reflected on the path route display screen M1 of the control terminal 22 when the path setting control based on the path setting information corresponding to the CH setting result on the CH setting result screen M4 up to 12 wireless devices 10 is executed normally. The contents are shown. Reference numeral 80 in the figure indicates a path route display. The line thickness and color can be changed depending on the number of selected CHs. Since the number of CHs varies depending on the type of the wireless device 10 (for example, the number of CHs that can be selected varies depending on the band of the wireless device 10), the line thickness and color are defined in advance as internal data of the control terminal 22. . If necessary, the data can be displayed at a predetermined location on the path route display screen M1 so that the user can change the setting. The thickness and color of the line can be defined, for example, if the same path route is 10, the red is a very thick line, the orange is a thick line if it is 5, and the yellow is a normal line if it is 1.

  FIG. 14 shows functions used when it is desired to check the current path setting information on the path route display screen M1 of the control terminal 22. In FIG. 14, it is possible to display the CH setting result screen M4 by the “left double click” operation using the mouse on the line as indicated by reference numeral 90. However, there are cases where a plurality of path routes are displayed on the path route display screen M1. In that case, the path selection screen M5 shown in FIG. 12 is displayed. In FIG. 3 wireless device 10 and No. 3 By executing “left double-click” operation of the mouse on the 9 radio apparatus 10 symbols, all the routes including the path are displayed on the path selection screen M5 of FIG. In FIG. 15, as an example, the path 1 is No. 1 to No. No. 12 as 1 route, path 2 3 to No. No. 18 as 1 route, path 3 3 to No. No. 22 as one route and path 4 3 to No. 9 indicates that there are a plurality of one routes.

  In the example of FIG. 14, since the path 2 is selected, the background color is displayed in gray. When the “OK” button is pressed in this state, the CH setting result screen M4 for the selected path 2 is displayed. On this CH setting result screen M4, if the user wants to change the CH, press the “Change CH” button in the same manner as described above to change the assigned CH setting on the screen to the desired CH, and click “OK”. ”Button, the starting point No. 3 on the CH setting result screen M4 is “No. SNMP Set” control information. If the control result is OK, the CH setting result screen M4 is updated with new information.

  Next, an outline sequence of the path setting operation on the control terminal 22 side will be described with reference to FIG. An operation program corresponding to this sequence is stored in a recording medium (not shown) in the control unit 104 and executed by a processor (CPU) in the control unit 104.

  First, the control terminal 22 opens the path route display screen M1 (step S101). Using the mouse, the user selects the symbol of the wireless device 10 at the important point of the path route to be stretched on the path route display screen M1 in the order in which the path route is to be stretched by the “left click” operation of the mouse. A “left double-click” operation of the mouse is performed on the symbol of the wireless device 10 to end the operation. However, if there is no free CH of the target wireless device 10 from the path management database 100 in the control terminal 22 or an Alarm state is detected, an error is displayed and the symbol of the wireless device 10 cannot be selected. In addition, the CH usage rate screen M2 can be displayed for the user's reference so that it can be determined whether or not the path route can be extended by a “right double-click” operation of the mouse on the symbol of the wireless device 10 for which the path route is desired. And

  Next, the control terminal 22 passes a path line from the network configuration information held in the network configuration information storage unit 109 to the symbol of the wireless device 10 at the start point to the symbol of the terminal wireless device 10 selected by the user in one route. Is confirmed to be a connection that can be closed without any problem (step S102). If a branch is included in the middle of the route, an error occurs. If there is no problem, proceed to the next operation.

  Next, the control terminal 22 refers to the path management database 100, and allows the number of CHs allowed from the selected device type (for example, the number of CHs that can be selected varies depending on the bandwidth of the device), all the user-selected channels. After confirming the status of free CHs in the wireless device 10 and the alarm occurrence information of all the wireless devices 10 selected by the user, the number of selectable CHs is determined, and the determination result is displayed on the CH number selection screen M3 (step S103).

  Next, the control terminal 22 searches for a CH that can be assigned from the path management database 100 with the number of CHs selected by the user on the displayed CH number selection screen M3, and the search result is displayed in the CH setting result screen M4. Above, the CH contents that can be assigned to each port are displayed (step S104).

  Next, on the CH setting result screen M4 displaying the search processing result, if there is a problem for the user to judge (for example, other CH is better), the “setting CH change” on the CH setting result screen M4 is displayed. Since the user can change to another selectable CH by pressing the button, the selection is changed (step S105). If there is no problem with the contents on the first CH setting result screen M4 searched by the control terminal 22, the process of step S105 is not performed.

  Next, when the user presses the “OK” button on the CH setting result screen M4 (step S106), the control terminal 22 moves from the control terminal 22 to the starting wireless device 22 by pressing the “OK” button. All the information on the path route, which is the path setting information on the CH setting result screen M4, is transmitted.

  Next, the control terminal 22 draws a line on the path route display screen M <b> 1 and returns it to the path management database 100 when the reply of the path route information setting from the starting wireless device 10 that transmitted all the information of the path route is OK. The setting contents are saved (step S107). The line display on the path route display screen M1 is displayed in a manner that is easy for the user to understand by changing the thickness and color depending on the number of channels. The “OK” button on the CH setting result screen M4 is set to Disable (invalid) in order to prevent the same data from being transmitted due to the successful control. When the path route information setting returns with an error, the error held in the “SNMP Trap” control information is displayed as error information on the screen of the control terminal 22 and the control is terminated.

  Next, an outline sequence of the re-open operation of the CH setting result screen M4 on the control terminal 22 side will be described using FIG. An operation program corresponding to this sequence is stored in a recording medium (not shown) in the control unit 104 and executed by a processor (CPU) in the control unit 104.

  First, the control terminal 22 opens the path route display screen M1 in order for the user to confirm the set path route on the screen of the display unit 110 of the control terminal 22 (step S201). The user uses the mouse to execute a “left double-click” operation on a line included in the path route to be confirmed on the path route display screen M1.

  Next, as a result of searching for necessary information from the path management database 100, the control terminal 22 opens the path selection screen M5 when determining that there are a plurality of paths on the selected line (step S202). If there is only one path, the path selection screen M5 is not displayed, and the process proceeds to the next process (step S204).

  Next, when it is determined that there are a plurality of paths on the selected line, the path that the user wants to display is selected from the displayed path selection screen M5 and executed (step S203).

  Next, the control terminal 22 displays the CH setting result screen M4 for the path route to be selected (step S204). The “OK” button on the CH setting result screen M4 is disabled (invalid), but if the user wants to change the setting contents, the user presses the “change setting CH” button on the CH setting result screen M4. When the value is changed, the “OK” button is displayed as Enable (valid), the changed content can be executed again by the “OK” button, and new control is also possible.
