Abstract
Methods and systems for performing multi-domain network slice selection and approval are provided. According to one aspect, a method performed by a Network Slice Selection Function comprises: receiving, from a requesting entity, a request for a network slice for use by a client device; upon determining that the network slice selection requires approval, identifying an Authorizing Network Function (ANF) for authorizing a network slice for the client device; determining a trust status of the ANF; identifying, based on the trust status, a network interface to use when communicating with the ANF; sending a slice selection authorization request to the ANF via the identified network interface; receiving from the ANF an approval status of a network slice; determining, based on the approval status and approval conditions, an allowed network slice; and sending, to the requesting entity, information including the allowed network slice.
