Problems solved by technology

[0002] The premise of realizing the comprehensive management of No. 7 signaling network based on signaling mining is to aggregate and share the data collected and processed by nodes at all levels. However, the existing network nodes have the characteristics of large number, geographical dispersion, and limited data transmission bandwidth in some areas. , thus posing challenges to the real-time collection, processing, transmission and aggregation of cross-regional, multi-level, and large-scale signaling data streams, which are embodied in two aspects: First, low bandwidth conditions easily lead to signaling data stream transmission network congestion, which is not conducive to the real-time aggregation and sharing of signaling data streams; second, large-scale signaling data streams must be aggregated to the back-end server for unified analysis and processing, which makes the server's storage and computing pressure greater, thereby reducing Timeliness of network management

Embodiment 1

[0020] Embodiment one, see figure 1 As shown, a signaling stream aggregation device based on stream combination compression includes a front-end signaling acquisition module and a back-end application server, and the front-end signaling acquisition module includes a signaling acquisition unit, a hash combination cache unit, and a compression aggregation unit , the signaling acquisition unit collects the signaling data packets transmitted on the signaling link in real time, the hash combination cache unit performs hash hashing on the collected signaling data packets, and the different messages of the same call are combined to form hash buckets, The compression and aggregation unit extracts the flag information of the relevant signaling data packets from the hash bucket to form a signaling summary, and uploads the signaling summary to the back-end application server.

Embodiment 2

[0021] Embodiment 2 is basically the same as Embodiment 1, except that the hash combination cache unit performs hash hash bucketing according to the source signaling encoding parameters, destination signaling encoding parameters, and circuit identification code parameters of the signaling data packet . The hash table maps a group of keywords to a limited address space according to the set hash function H (key) and the method of dealing with conflicts, and uses the image of the keyword in the address space as a record in the table The storage location, and the resulting storage location is called a hash address or a hash address. Due to the large amount of signaling data received from the backbone network and the superimposition of many calls, the hash algorithm can be used to quickly search and store the same signaling data. In this patent, the source information of the signaling data packet The command encoding parameter, the destination signaling encoding parameter and the ...

Embodiment 3

[0024] Embodiment three, see figure 2 , a signaling flow aggregation method based on flow combination compression, comprising the following steps:

[0025] Step 1: Collect signaling data packets transmitted on the signaling link in real time;

[0026] Step 2: The signaling data packets are hashed and cached in buckets according to the source signaling point encoding parameters, destination signaling point encoding parameters and circuit identification code parameters, and several different signaling data packets of the same call are combined to form hash bucket;

[0027] Step 3: When the call end message is collected, extract the corresponding signaling data packet from the hash bucket corresponding to the call, and extract the signaling parameters in the signaling data packet to form a signaling summary;

[0028] Step 4: Upload the signaling summary to the backend application server.
