Embodiment 1

[0076] Figure 6 It is a structural schematic diagram according to the preferred embodiment 1 of the present invention, such as Figure 6 As shown, in the network scenario where the Radius message can be obtained from the mobile Internet gateway, in this embodiment, the structural composition, deployment location and data flow direction of the log collection device in a distributed deployment mode are as follows:

[0077] The distributed device is realized by adding network elements in the operator's mobile data network in the related art. Deploy the Radius message processing module 1 in the topology of the mobile data network architecture to enable it to access the mobile Internet gateway. The Radius message processing module 1 is responsible for obtaining Radius messages from the mobile Internet gateway, parsing the Radius messages and obtaining user identification information IMSI, MSISDN, and PDP activation. Time, private network IP address and private network port number...

Embodiment 2

[0083] Figure 8 It is a structural schematic diagram according to the preferred embodiment 2 of the present invention, such as Figure 8 As shown, when the Radius message cannot be obtained through the mobile Internet gateway, that is, in the network environment where the Radius message acquisition condition is limited, the structural composition, deployment location and data flow of the user's online log collection device are as follows:

[0084] The device is also implemented by adding network elements in the mobile data network of the operator in the related art. It deploys the signaling collection and processing module 2 in the topology of the mobile data network architecture to access the interface between the Internet service support node (such as SGSN (ServingGPRSSUPPORTNODE) ​​in the 3G network, MME (Mobility Management Entity) in the 4G network) and the mobile Internet gateway, and the firewall logs The processing module 3 is connected to the NAT firewall. Through ...

Embodiment 3

[0093] The firewall log processing module 3 is connected with the NAT device of the network firewall, obtains the NAT log from the NAT device of the network firewall, and analyzes the NAT log to obtain NAT conversion information. The NAT conversion information includes: source private network IP address, source private network port number , source public network IP address, source public network port number, destination IP address, destination port number, NAT start time and NAT end time, and NAT conversion information group package is sent to log data merging module 4 for and Radius message processing module 1 or the user identification information, private network IP address and private network port number sent by the signaling collection and processing module 2 are associated and merged;

[0094] Figure 10 It is the workflow diagram of the NAT log processing module 3 according to the preferred embodiment 3 of the present invention, as Figure 5 As shown, the process inclu...

Abstract

The invention discloses an online log generation method and apparatus. The method comprises the steps of acquiring private network information of a user through a user control panel message GTP-C of a network; acquiring network address translation (NAT) of the user; and generating an online log of the user based on the acquired private network information and the NAT information. The invention can be used for solving the problems in the prior art that the private network information of the user cannot be acquired through an Radius message and thus cannot be combined with the NAT information to generate log information of the user, acquisition of the private network information of the user through the GTP-C provides mobile user online data query support for national security regulatory authorizes, and the reliability and scalability are also very high.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for generating an online log. Background technique [0002] In recent years, with the rapid development of mobile access technologies such as the third generation of mobile communication 3G and Long Term Evolution (LTE for short), combined with the combination of highly intelligent mobile terminals, mobile data services are combined with mobile communication and the advantages of the Internet. However, the number of public IP addresses in the world is almost exhausted. Usually, telecom operators use a firewall technology to solve this problem. The firewall is the gateway connecting the mobile access network and the Internet. Internet Protocol (abbreviated as IP) address is translated into an idle public IP address in the firewall address pool. Specifically, telecom operators will assign a private network IP address to mobile users who are going to access t...
