FIG. 4 is a flowchart of a method for ordering signaling between network elements according to a third embodiment of the present invention. As shown in FIG. 4, in the embodiment, the method for sequencing signaling between network elements includes the following steps:

S401: Trigger signaling sequence sorting process.

The client directly opens the signaling file to trigger the process of intelligent sequencing of signaling. The process includes the following steps: the network management system has collected the signaling reported by each network element and summarized it into a signaling file; the client requests to open the server file, the network management server triggers the intelligent sorting process, or the network management server periodically performs the buffer signaling analysis. Trigger signaling intelligent sorting.

The client requests to open the server file, and the server triggers the business process of the smart sort process. The process includes the following steps: the network management client establishes a connection with the server; the network management client creates a tracking task, and the signaling is normally reported to the server by each network element; the network management server caches the signaling file; the client requests to open the server signaling. The analyzed file; the network management server triggers analysis and processing of the cache signaling file according to the client request.

The server periodically performs cache signaling analysis, triggers a signaling intelligent sorting process, and the client views the business process of the analyzed file. The process includes the following steps: the network management client establishes a connection with the server; the network management client creates a tracking task, and the signaling is normally reported to the server by each network element; the network management server caches the signaling file; the network management server periodically buffers the signaling The file is analyzed and processed.

S402: Determine an associated signaling pair from the cache signaling file.

In the communication service, both the initiating and receiving NEs of a signaling interaction report a message to the network management system. The network management system needs to be able to associate the two messages to form a true network element signaling interaction. To associate two messages, the network element needs to provide an association ID in the report message. If the NE cannot provide the association ID, you can also obtain the MD5 code for the message content. Since the sender and receiver messages have the same content, MD5 must be the same after the MD5 algorithm. If the message is different, the acquired MD5 must be different. The present application can perform the determination of the associated signaling pair according to the association ID or MD5 in the signaling.

Referring to FIG. 3, the buffer signaling file includes signaling 1-12, and the network management server determines signaling 3 and signaling 12, signaling 4 and signaling 1, signaling 2, signaling 8, and signaling 6 according to the foregoing method.

The embodiment uses the network element C as a reference network element.

S404: Sort the associated signaling pairs based on the reference network element, and generate an original signaling sequence.

The source NEs or destination NEs are sorted in the same order as the NEs are reported. The two sets of signaling are different for the associated network elements involved, and then the signaling time is compared for sorting. The signaling pair is in the order of transmission first and reception.

This step includes the following substeps:

Whether the source network element of the first signaling pair is the source network element of the second signaling pair, and if yes, sorting the signaling pair according to the above sequence number of signaling signaling; if not,

Determining whether the source network element of the first signaling pair is the destination network element of the second signaling pair, and if so, sorting the sequence number according to the first signaling pair sending signaling and the second signaling pair receiving signaling Right; if not, then

Determining whether the destination network element of the first signaling pair is the destination network element of the second signaling pair, and if yes, sorting the sequence number according to the first signaling pair receiving signaling and the second signaling pair receiving signaling Right; if not, then

Determining whether the sending time of the first signaling pair and the sending time of the second signaling pair are sortable, and if so, sorting the time sequence according to the first signaling pair sending signaling and the second signaling pair sending signaling Right; if not, then

Determining whether the sending time of the first signaling pair and the receiving time of the second signaling pair are sortable, and if so, sorting the time sequence according to the first signaling pair sending signaling and the second signaling pair receiving signaling Right; if not, then

Determining whether the receiving time of the first signaling pair and the sending time of the second signaling pair are sortable, and if so, sorting the time sequence according to the first signaling pair receiving signaling and the second signaling pair sending signaling If yes, the signaling pair is sorted according to the chronological order of the received signaling in the first signaling pair and the received signaling in the second signaling pair.

S405: Insert single point signaling into the original signaling sequence based on the sending order of the network element, and return the sorting result.

The inserted policy is to insert according to the time sequence of the same network element, find the sending network element of the single point signaling, find the location of the previous signaling of the single point signaling according to the sequence number, and insert the single point signaling into the After finishing the sort. As can be seen from FIG. 3, since there is signaling 12 transmitted by the A network element in the associated signaling 1, the single point signaling 5 and 11 are inserted above the associated signaling pair 1.

S406: The sorted result is returned, and the network management performs further rendering, and the rendering result and the data are returned to the network management for display, and the process of opening the signaling file ends.
