Network slice selection method, radio access device, and terminal

A radio access network (RAN) device, comprising:

• a processor configured to obtain network slice information comprising first attribute information of at least two different network slices of a first network;
• a transmitter coupled to the processor and configured to send a first message to a terminal, wherein the first message comprises the network slice information;
• and
• a receiver coupled to the processor and configured to receive a first access request message from the terminal, wherein the first access request message comprises second attribute information of a first network slice, of the at least two different network slices, to be accessed by the terminal, and
• wherein the processor is further configured to select, based on the second attribute information of the first network slice, a second network slice, of the first network, to be accessed by the terminal.

A network slice selection system, comprising:

• a terminal;
• and
• a radio access network (RAN) device coupled to the terminal and configured to:
• obtain network slice information comprising first attribute information of at least two different network slices of a first network;
• and
• send, to the terminal, a first message comprises comprising the network slice information,
• wherein the terminal is configured to:
• select, based on the network slice information, second attribute information of a first network slice, of the at least two different network slices, to be accessed by the terminal;
• and
• send a first access request message to the RAN device, wherein the first access request message comprises the second attribute information of the first network slice, and
• wherein the RAN device is further configured to select, based on the second attribute information of the first network slice, a second network slice, of the first network, to be accessed by the terminal.
