Rogue network function detection and isolation in a communication network

There is provided an apparatus comprising: means for providing, to a network repository function, a discovery request comprising a preferred locality query parameter, wherein the preferred locality query parameter comprises a plurality of location descriptions, and means for receiving, from the network repository function, a response to the discovery request, wherein the response comprises one or more service producers that match the preferred locality query parameter.

Method, apparatus and computer program

There is disclosed an apparatus. The apparatus comprises means for performing: initiating establishment of an N32-c transport layer security connection with an entity, the apparatus located in a first public land mobile network and the entity located in a second public land mobile network; sending from the apparatus to the entity on the N32-c transport layer security connection an N32-c handshake signalling message comprising domain name information of the apparatus to be used by the entity for establishing an N32-f transport layer security connection towards the apparatus; receiving a reply from the entity, the reply comprising domain name information of the entity to be used by the apparatus for establishing the N32-f transport layer security connection towards the entity; and using the domain name information received in the reply to establish the N32-f transport layer security connection towards the entity.
