Abstract: 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.

Abstract: An apparatus of a communication network system, which routes data packets and stores trusted routes between different communication network systems in a database, detects (S12) that a data packet requires a route with a specific level of trust, determines (S13), from the trusted routes stored in the database, a specific trusted route towards a destination as indicated in the data packet, and sets (S15) the data packet on the specific trusted route towards the destination.

Abstract: 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.

Abstract: Some embodiments of the present invention relate to an apparatus, a method, and a computer program product related to coexistence of two network operators, for example a local operator and an incumbent operator. In certain embodiments, a method may include monitoring if network information from a server part of an application is received by a client part of the application. The client part is connected to the server part via a first network that uses a radio access technology. The network information is related to a second network that uses the radio access technology, the second network being different from the first network. The method also includes controlling a cellular radio layer such that it interworks with the second network based on the received network and authentication information.
