Abstract
This disclosure relates to methods and apparatuses for protection of control plane functionality of a network node of a communications network providing wireless communication to a mobile terminal. The network node is configured to support control plane signaling with the mobile terminal. A communication context for the mobile terminal is maintained, wherein the communication context is associated with a control signaling message exchange between the mobile terminal and the network node. One method includes establishing, for a received message, a communication context to which it belongs; determining, in relation to information in the established communication context, the received message to be a message conforming to a protection rule or a message violating a protection rule; and handling the message in accordance with rules of a protection policy. Related network nodes, computer programs, and computer program products are disclosed.
