1. A method in a network repository function (NRF) for providing a service discovery service to a network function (NF) instance, the method comprising:
the NRF receiving a discover request transmitted by the NF instance, wherein the discover request comprises a set of one or more query parameters; and
the NRF producing, based on a search criteria based on query parameters included in the discover request, a search result comprising NF instance profiles that match the search criteria;
the NRF storing the search result comprising NF instance profiles that match the search criteria; and
the NRF transmitting a discovery response comprising at least one of the NF instance profiles that match the search criteria, wherein
the discover response further comprises an identifier for identifying the stored search result that comprises the NF instance profiles that match the search criteria, and
the identifier enables the NF instance to obtain the stored search result.
