    摘要: A method comprises acquiring (201), in a network node (NE1), data transmitted between network nodes of a communication system. The network node (NE1) processes (202) the acquired data in order to optimize data scanning in the communication system, and provides (203) an output indicating selected data fields for which data scanning is to be performed. The processing (202) of the acquired data comprises classifying data fields of a data set based on selected data scanning characteristics of the data fields, calculating, based on the classifying, the sensitivity of the data fields, forming a first partial order of the data fields based on their sensitivity, forming a second partial order of the data fields based on their usage, and sorting, based on the first and second partial order, the data fields into data scanning categories.

    摘要: A user plane network entity of a 5G core network performs: obtaining GPRS Tunneling Protocol User Plane (GTP-U) tunneling information of a new or updated protocol data unit (PDU) session from a control plane network entity of the 5G core network; and adjusting according to the obtained GTP-U tunneling information a GTP-U firewall for selectively allowing to pass through only GTP-U traffic concerning GTP-U tunnels defined by the GTP-U tunneling information. The control plane network entity performs: obtaining from control plane signaling the GTP-U tunneling information and communicating same to the GTP-U firewall. A system containing the user plane network entity and the control plane network entity is also disclosed.

    摘要: This document discloses a solution for detecting and mitigating anomalies such as signalling storms in a radio access network of a wireless communication system. According to an aspect, there is disclosed a method including receiving, in a first local traffic analysis module, configuration parameters from a second local traffic analysis module or from a central traffic analysis module connected to a plurality of local traffic analysis modules; monitoring, by a first traffic analysis module by using the received configuration parameters, traffic in a radio access network of a wireless communication system; detecting, in the monitored traffic on the basis of the configuration parameters, an anomaly causing a control plane signalling load; and in response to said detecting, taking an action to mitigate the anomaly and reporting information on the anomaly to the central traffic analysis module.
