摘要
A method for providing for policy-based access and mobility management function (AMF) selection using network slice selection assistance information (NSSAI) availability information obtained from an NSSAI availability service includes, at a network slice selection function (NSSF) including at least one processor, obtaining, from an NSSAI availability service, NSSAI availability information regarding a plurality of AMFs. The method further includes receiving, from a first AMF, a network slice selection request specifying a network slice service requested by a user equipment (UE). The method further includes generating, based on the NSSAI availability information and the network slice service requested by the UE, a prioritized list including an identity of at least one AMF for supporting the network slice service. The method further includes communicating the prioritized list to the first AMF.
