Abstract
A traffic analysis system monitors data traffic in a communication network. In the data traffic, flows are detected which are based on the Hypertext Transfer Protocol (HTTP). For each of the flows, a data record is created. The data record comprises at least a User Agent identifier from a message header of a HTTP message of the flow and a device identifier of a user equipment transmitting the flow. The data records are analyzed to determine a mapping of at least one User Agent identifier in the data records to a corresponding device category.
Claims13
A method for analyzing data traffic in a communication network, the method comprising:
- monitoring data traffic in the communication network;
- detecting flows in the data traffic which are based on the Hypertext Transfer Protocol;
- for each of the flows, creating a data record comprising:
- a User Agent identifier from a message header of a Hypertext Transfer Protocol message of the flow, and
- a device identifier of a user equipment transmitting the flow;
- analyzing the data records to determine a mapping of at least one User Agent identifier in the data records to a corresponding device category;
- and
- on the basis of the mapping, controlling access of user equipments to the communication network.
A node for a communication system, the node comprising:
- at least one interface for monitoring data traffic in the communication network;
- and
- at least one processor, wherein the at least one processor is configured to:
- detect flows in the data traffic which are based on the Hypertext Transfer Protocol;
- for each of flows, create a data record comprising:
- a User Agent identifier from a message header of a Hypertext Transfer Protocol message of the flow, and a device identifier of a user equipment transmitting the flow;
- analyze the data records to determine a mapping of at least one User Agent identifier in the data records to a corresponding device category;
- and
- on the basis of the mapping, control access of user equipments to the communication network.
