Send a monitoring alarm report message. The data communication interface in the communication module defines the communication mode, which is the communication channel between the client and the server; the data format interface defines the format of the data transmission, and both the client and the server need to be called.

The following describes the process of transmitting the 3G network topology information by the above system. As shown in FIG. 2, the following steps are included: Step 201: The client device starts and initializes. Step 202: The client device sends a query message to the server, where the query message is used to request each network element information from the server. Step 203: After receiving the query message, the server feeds back the network element information. To the client device; Step 204: The client device receives the network element information, and completes the information model module according to the received network element information;

Step 205: The client device continues to send a query message to the server to obtain a link message, a packet, and office route information between the network elements. Step 206: The server receives the query message, invokes the link query, the office route query, and the like. The query module queries the information, and then sends the query result to the client device. In this step, the server can send the query result to the client device by listening to the message. Step 207: After the server sends all the topology information, send a request to open the network topology view to the client device (that is, notify the client that the complete topology information has been sent); Step 208: The client device receives the open network. The topology view request is performed to perform the topology view initialization operation; specifically, the service processing module is invoked by the topology interface in the client device to perform the view initialization operation;

Step 209: The client device generates a first layer topology view according to the received complete topology information data. In this step, the service processing module in the client device invokes the information model, and the data in the information model is gradually displayed on the view. The information of the network element, the link, the direct connection of the network element, and the alarm is generated to generate the first layer topology view. Step 210: The client device receives the topology view request initiated by the user to open a direct connection office direction. Re-initializing a window for displaying the second-level topology view; in this step, the business processing module in the client device re-initializes a window for displaying the second-level topology view; Step 211: The client device reads Request the direct connection office information, and send the direct connection to the letter Information and its link status are displayed on the topology interface (ie, displayed through the second layer topology view); in this step, the processing module in the client device invokes the information model to read the requested direct connection office information, and The obtained collimated connection direction and its link status are displayed on the topology interface. In the above process, when the server notifies the client device of the query result of the information such as the link and the office route, the notification information carries the ID of the requesting query client, and the client device receives the message carrying the query result, and compares the message. Whether the ID carried in the ID and its own ID are consistent, and only when they are consistent, the topology view is generated according to the query result in the message.

In the above process, the specific process of the information model processing in the client device, as shown in FIG. 3, includes the following steps: Step 301: The client device starts; Step 302: Start the information model initialization thread; Step 303: Set the information model initialization Marked as "No"; the information model initialization flag is mainly used for the judgment basis when the user requests to open the topology view, that is, when the information model initialization flag is no (that is, the network element information in the information model is not initialized), Open the view immediately, you need to wait for the NE node information of the information model to be initialized before you can open it. Step 304: The client device sends a query message to the server, where the query message is used to query the network element information (such as the basic information of the network element such as the network element location). Step 305: The client device receives the network element information returned by the server. The information model is initialized according to the query result. Step 306: The client device sends an inquiry message to the server through the asynchronous message, and the message is mainly used to query other information except the network element information (ie, the link information of the network element and the office route information, etc.) When the client device receives the query result returned by the server, the information model module is notified to update; in this step, the client device can start an asynchronous message receiver, and is used to determine whether the query result is received; When the Park view is opened, the business logic processing module can be updated without notifying the view, so that when the topology view is opened, the user can be prevented from waiting too long. Step 307: Set the information model initialization flag to "Yes"; Step 308: The information model initialization ends.

The specific process of the client device opening the topology view, as shown in FIG. 4, includes the following steps: Step 401: The client device accepts the request to open the topology view; Step 402: Determine whether the information model initialization is completed, and if yes, proceed to step 403. Otherwise, repeat this step;

In this embodiment, the view can be opened only after the information model has initialized the network element information. Otherwise, after waiting for 2S, continue to determine whether the information model is initialized. Step 403: Initialize the network element on the topology view. In order to speed up the display of the view, after the network element information is initialized, the topology view can be presented to the user, and subsequent other information starts a separate thread to be loaded according to the information model. Step 404: Open the view and start a subsequent processing thread. The subsequent processing thread includes: initializing the link information according to the information model, initializing the direct office direction information, initializing the link state information, and initializing the alarm information.

The process of the monitoring module in the client device, as shown in FIG. 5, includes the following steps: Step 501: The office route monitoring module in the server monitors whether any network element performs an office route related command in real time;

Step 502: When the authority obtains the office direction change information from the monitoring module, it determines whether it is adding or deleting the office direction. If yes, the process proceeds to step 503, otherwise, the process returns to step 501. Step 503: The server broadcasts the message to all clients through the jms message. Step 504: The listening module acquires the message in the client device. Step 505: The client device notifies the information model module and the processing module to perform update processing. The module is mainly to ensure that the latest changes can be reflected in the topology view in time when the topology view is already open. Step 506: Determine whether the change office direction is the direct connection direction. If yes, go to step 507, otherwise go to step 508; Step 507: Determine whether the first layer topology view is open, and if yes, open the topology view. Update the process, otherwise, the process is terminated. Step 508: The change office direction is the collimation direction, and the direct connection office of the collimation connection is inquired according to the information model, and the direct connection is determined. Whether the second layer topology view of the office office is open, if yes, proceed to step 509, otherwise, the process is terminated; step 509: update the attempt, and end the process.

The invention may, of course, be embodied in a variety of embodiments without departing from the spirit and scope of the invention, and any modifications, equivalents, and improvements made within the spirit and scope of the invention are included in the present invention. Within the scope of the appended claims.
