A Machine Type Communication Inter Working Function (MTC-IWF) entity (1) is configured to, in response to receiving from a Service Capability Server (SCS) a first request for quality of service to be applied to a specific communication of an MTC device, send to a Policy and Charging Rule Function (PCRF) entity a second request for applying the quality of service to the specific communication. It is thus possible, for example, to facilitate controlling quality of service of a specific communication in a Public Land Mobile Network (PLMN) in response to a request by the SCS for the quality of service.
