Embodiment Construction

[0024] figure 1 It is a schematic diagram of the network location of the device associated with traffic and user information according to an embodiment of the present invention.

[0025] figure 1 Among them, the SGSN device 110 is the GPRS service support node, which is used to manage mobile user data, such as user identification, encryption, etc.; the GGSN device 130 is the GPRS gateway support node, which has the function of distributing the IP address of the terminal and the gateway to the external network . The SGSN device 110 performs information exchange with the GGSN device 130 through the switch 120 , that is, the switch 120 transmits data packets to each other.

[0026] The SGSN device 110 and the GGSN device 130 are connected through a switch 120, which can be any common switch, which provides a shared electrical signal path for the SGSN device 110 and the GGSN device 130, so that the SGSN device 110 and the GGSN device 130 can Complete the information exchange. ...

Abstract

The invention relates to a method and a system for correlating flow and user information in a GRPS network. The method comprises the following steps of: firstly, receiving a data packet of a control type and analyzing the data packet; secondly, adding one or more of the analyzed tunnel number, state, mobile phone internet protocol (IP) address and user information into nodes of a state HASH list;thirdly, adding the mobile phone IP address and user information of the nodes in the state HASH list into the node of a user HASH list; fourthly, receiving a data packet of a data type and unpacking the data packet to obtain the mobile phone IP address of a user to which the data packet belongs; and finally, searching for the user HASH list by using the mobile phone IP address as a keyword to obtain the information of the user to which the data packet belongs so as to correlate the flow and the user information. The method and the system can be applied to the system which is required to acquire the correlation of the network flow and the user.

Description

technical field [0001] The present invention relates to computer networks, in particular to GPRS networks. Background technique [0002] The number of mobile users in China is huge and the competition among operators is fierce. Therefore, it is necessary to keep abreast of user needs and preferences in a timely manner to enhance their own competitive advantages. Mobile Internet analysis equipment solves this problem, and it can quickly provide operators with the first market response. However, due to the complex layout of the telecom core network, the service support gateway (GSN) does not have a corresponding user information interface, so it cannot be directly passed The service supports the gateway (GSN) to obtain the association between traffic and user information. [0003] GPRS (General Packet Radio Service, general packet radio service technology) is a wireless packet switching technology based on the GSM system, which can provide end-to-end wide-area wireless IP con...
