Providing slice attribute information to user equipment in a mobile network environment

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations, comprising:

• obtaining, by a network element of a mobile core network, a registration request for connection of a user equipment to the mobile core network;
• performing an authentication for connection of the user equipment to the mobile core network;
• and
• upon successful authentication of the user equipment for connection to the mobile core network, providing, by the network element, a registration response to the user equipment, 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 one of:
• attribute information for each of the plurality of network slice types or 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 of the plurality of network slice types is to be obtained by the user equipment, wherein based on the network location information being identified in the registration response, the user equipment is to query one of the application server or the DNS server utilizing the network location information to obtain the attribute information for each of the one or more of the plurality of network slice types following session establishment by the user equipment with a default network slice type.

A network element comprising:

• at least one memory element for storing data;
• and
• at least one processor for executing instructions associated with the data, wherein executing the instructions causes the network element to perform operations, comprising:
• obtaining, by a network element of a mobile core network, a registration request for connection of a user equipment to the mobile core network;
• performing an authentication for connection of the user equipment to the mobile core network;
• and
• upon successful authentication of the user equipment for connection to the mobile core network, providing, by the network element, a registration response to the user equipment, 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 one of:
• attribute information for each of the plurality of network slice types or 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 plurality of network slice types is to be obtained by the user equipment, wherein based on the network location information being identified in the registration response, the user equipment is to query the one of the application server or the DNS server utilizing the network location information to obtain the attribute information for each of the one or more of the plurality of network slice types following session establishment by the user equipment with a default network slice type.
