  • Publication number: 20180114021
    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.

  • Publication number: 20180041897
    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.
