Abstract
The present method and system perform context aware deep pack inspection in a mobile IP data network. For doing so, the method and system collect real time data from mobile IP data sessions, analyze the real time data and differentiate user data traffic from control traffic. Then, the method and system extract control information from the control traffic and create a subscriber context. The subscriber context comprises the at least one unique identifier and the corresponding IP address.
Claims14
A system for performing context aware deep packet inspection in a mobile IP data network, the system comprising:
- a pre-processing unit for collecting real time data from mobile IP data sessions, analyzing the real time data and differentiating data traffic from control traffic;
- a Deep Packet Inspection (DPI) unit for:
- extracting control information from the control traffic and creating a subscriber context, the control information comprising a unique identifier of a mobile device and an IP address allocated to the mobile device, the subscriber context comprising the unique identifier of the mobile device and the IP address allocated to the mobile device;
- and
- extracting user data information from the data traffic, the user data information comprising the IP address of the mobile device and a classification of an application used on the mobile device;
- and
- a value added data analysis unit for correlating the user data information with a corresponding subscriber context, the correlation consisting in matching the IP address of the mobile device comprised in the user data information with the IP address allocated to the mobile device comprised in the corresponding subscriber context.
A method for context aware deep packet inspection in a mobile IP data network, the method comprising:
- collecting real time data from mobile IP data sessions;
- analyzing said real time data to differentiate a data traffic from a control traffic;
- extracting control information from the control traffic by means of a DPI unit and creating a subscriber context, the control information comprising an unique identifier of a mobile device and an IP address allocated to the mobile device, the subscriber context comprising the unique identifier of the mobile device and the IP address allocated to the mobile device;
- extracting user data information from the data traffic by means of the DPI unit, the user data information comprising the IP address of a mobile device and a classification of an application used on the mobile device;
- and
- correlating the user data information with a corresponding subscriber context, the correlation consisting in matching the IP address of the mobile device comprised in the user data information with the IP address allocated to the mobile device comprised in the corresponding subscriber context.
