Abstract
A node of the wireless communication network receives data indicative of a measured QoS, level of data traffic assigned to different configured traffic forwarding policies each defining one or more target parameters. Based on the data and the target parameters, the node detects violations of the traffic forwarding policies. Based on the detected violations for each the traffic forwarding policies, the node detects at least one anomaly in the wireless communication network.
Claims20
A method of controlling user data traffic in a wireless communication network, the method comprising:
- a node of the wireless communication network receiving data indicative of a measured Quality of Service (QOS) level of data traffic assigned to different configured traffic forwarding policies each defining one or more target parameters;
- based on the data and the target parameters, the node detecting violations of the traffic forwarding policies;
- and
- based on the detected violations for each of the traffic forwarding policies, the node detecting at least one anomaly in the wireless communication network, wherein detecting the at least one anomaly includes, for each traffic forwarding policy, determining a ratio of data records corresponding to the detected violations to a total number of data records for that traffic forwarding policy.
