1. A method comprising:
communicating, by a user equipment, a registration request to a mobile core network for connection of the user equipment to the mobile core network;
obtaining, upon successful authentication of the user equipment for connection to the mobile core network, a registration response, wherein the registration response identifies a plurality of network slice types with which the user equipment is authorized to establish a session and the registration response identifies network location information associated with one of an application server or a Domain Name System (DNS) server from which attribute information for one or more corresponding network slice types of the plurality of network slice types is to be obtained by the user equipment;
performing, by the user equipment, session establishment for a default network slice type of the plurality of network slice types; and
following the session establishment with the default network slice type, performing one or more corresponding query toward one of the application server or the DNS server utilizing the network location information identified in the registration response to obtain corresponding attribute information for each of the one or more corresponding network slice types of the plurality of network slice types from one of the application server or the DNS server.
