Network shunt mobile Internet acquisition Scheme! Rongteng network usually we divide the network into fixed network and mobile Internet two big categories!
Compared with the traditional internet, mobile internet has two notable features: mobility, control and load separation. Mobility requires telecom operators to provide users with the ability to access the Internet anytime, anywhere. The separation of control and load brings about complex network structure and bearer protocol. In the LTE core network EPC, the GTPV2-C protocol is hosted on the S11 and S10 interfaces, and S6A and SCTP protocols are based on S1AP on the S1-mme and diameter interfaces, and s1-u protocols exist on the Gtp-u interface. The need to parse and correlate protocols for multiple interfaces to get complete information from a single user poses a huge challenge to data traceability.
Aiming at the demand of the police collector and the above-mentioned technical features, the series of collectors developed by the Rongteng network adopt FPGA+NPU architecture, complete the parsing and correlation of the signaling, generate the user's downline information in XDR format, and implement data filtering and decentralization based on five-tuple rules, mobile number rules and DPI rules. And at the end of the decentralization message contains user information (including IMSI, IMEI, MSISDN and ecgi information, customizable) data labels. Back-end analysis system to analyze any valuable information, can be linked in real-time to the location of the application, mobile phone number, device number and other information.
The typical network mode of police mobile internet collectors is shown in 21. From the EPC S1-mme, S11, S10, S1-u and s6a interface, can be directly input to the collector, but also through the aggregation of equipment and then input to the collector, the output data of the collector can be directly output to the back-end restore system, You can also deploy a shunt switch between the two two load-balanced shunts based on the Dmac.
Rongteng's mobile Internet collection provides several advantages for customers:
1) in the lower end of the user face message carrying data labels, so that the back-end server does not have to parse the signaling surface data and the user surface data related traceability, reduce the demand for resources of the backend server;
2) A single mobile internet collector can handle multiple carrier data at the same time, the message processing process does not affect each other, and the different operators of the data in accordance with their respective output group decentralized, non-interference, thereby greatly saving the user's equipment investment;
3) The Exchange card uses the FPGA+NPU architecture, completes the data exchange simultaneously completes the signaling processing and the correlation, does not need the separate signaling analytic board, further reduces the equipment cost;
4) accurate and rich multi-level message decentralization mechanism, so that the splitter can maximize the filtering of unrelated traffic, accurately decentralized customer care and needs of data.
