Abstract
A network function (NF) repository function (NRF) suitable for use in a 5G mobile network utilizing segment routing (SR) is described. The first interface of the NRF may be an Nnrf interface with a service discovery function. The second interface of the NRF may be for use with a SR path information obtaining function for interfacing with a SR path computation entity (SR-PCE). The service discovery function may be further configured to discover NF instances based on identifying an NF instance being associated with SR path information that accords to least one service, application, or subscription requirement obtained according to the discovery request.
