1. A method of handling a discovery request in a network, performed by a network repository function (NRF) node, the method comprising:
receiving the discovery request; and
initiating transmission of a discovery response towards a network node that initiated transmission of the discovery request towards the NRF node;
wherein the network node is a first network function (NF) node of a service consumer or a first service communication proxy (SCP) node that is configured to operate as an SCP between the first NF node and second NF nodes of at least one service producer;
wherein the discovery request is a request for information indicative of one or more second NF nodes for providing a service requested by the first NF node;
wherein the discovery response comprises:
first information indicative of a plurality of second NF nodes identified for providing the service;
second information indicative of whether the plurality of second NF nodes identified for providing the service are identified based on a criterion; and
third information indicative of whether the plurality of second NF nodes are prioritized according to the criterion; and
wherein the plurality of second NF nodes support a change to a priority already assigned to at least one second NF node of the plurality of second NF nodes to allow the plurality of second NF nodes to be prioritized according to the criterion.
