A method performed by a subscriber's data node for differentiating Non-IP Data Delivery, NIDD, traffic in a communication network. The communication network comprises the subscriber's data node, a serving node and an exposure function node. The subscriber's data node receives, from the exposure function node, a NIDD authorization request comprising a first identifier. The first identifier comprises any one out of a service capability server identifier, an application server identifier and an application function identifier. The subscriber's data node generates a non-IP flow description, based on the received first identifier. The non-IP flow description comprises an application identifier and a non-IP flow identifier for the NIDD authorization. The subscriber's data node transmits the non-IP flow description towards the serving node. The subscriber's data node transmits a NIDD authorization response comprising the non-IP flow identifier, towards the exposure function node.
