Systems and methods for handling telescopic fqdns

Abstract

Disclosed herein is a method performed by a first node (420) implementing a first NF in a visited network (VPLMN) for communicating with a third node implementing a second NF in a home network (HPLMN). The method comprises the steps: determining (400) that the third node should be communicated with; sending (402) towards a second node (440) implementing a Security Edge Protection Proxy (SEPP) in the visited network, a request for a telescopic FQDN for the third node in the home network to be used by the first node in the visited network to communicate with the third node in the home network, which request comprises a FQDN of the third node in the home network; receiving, from the second node, a telescopic FQDN for the third node wherein the FQDN for the third node in the home network is flattened to a single label to be used by the first node to communicate with the third node.
