The respective data delta comprises only categorization data that is updated compared to categorization data relating to a point in time that is earlier than the subsequent point in time. Upon receiving () from the first device, a call invitation to the second device, the IMS node enforces () a policy relating to categorizing the type of communication of the call, to establish a trust level associated with the first device. The enforcing is based on whether a data delta relating to the first device is obtained among the number of obtained data delta relating to the number of devices.
