Communication method and apparatus using network slicing
View Patent ↗Provided is a communication method and apparatus using network slicing. A communication method of a communication apparatus performing communication with a user equipment receives a predetermined request from the user equipment, selects a single network slice instance to be allocated to the user equipment from among a plurality of network slice instances in the communication apparatus in response to the request, selects a single network function instance to be allocated to the user equipment from among a plurality of network function instances included in the selected network slice instance. The network slice instance is in an instantiated form of a network slice that includes at least one network function and resource for providing a network service having a predetermined capability and characteristic to the user equipment.
1. A communication method, the method comprising:
identifying a S-NSSAI (single network slice selection assistance information) of a network slice for a network; and
selecting the network slice using the S-NSSAI,
wherein the network slice is logical network which provides a network capability and a network characteristic,
wherein the S-NSSAI includes a slice/service type (SST), which refers an expected behavior of the network slice in terms of a feature and a service and wherein the S-NSSAI includes a slice differentiator (SD) which complements a slice/service type.
2. The method of claim 1 , wherein the network slice is different from features and network functions optimization.
3. The method of claim 1 , wherein the network slice includes core network control plane and user plane network function.
4. The method of claim 1 , wherein a single user equipment is served with one or more network slice instances via an access network,
wherein the network slice instance is network function instance and a resource for the network slice.
5. The method of claim 4 , wherein a PDU(protocol data unit) session belongs to one network slice instance per PLMN(public land mobile network).
6. The method of claim 1 , wherein the S-NSSAI is included in subscription information, and is marked as default.
7. A communication method, the method comprising:
providing a requested NSSAI(network slice selection assistance information) including at least one of S-NSSAI corresponding to a network slices which a user equipment wishes to register;
registering the user equipment with a PLMN(public land mobile network),
wherein the network slice is logical network which provides a network capability and a network characteristic,
wherein the S-NSSAI includes a slice/service type (SST), which refers an expected behavior of the network slice in terms of a feature and a service and wherein the S-NSSAI includes a slice differentiator (SD) which complements a slice/service type.
8. The method of claim 7 , wherein the requested NSSAI includes (i) a configured-NSSAI, and (ii) an allowed-NSSAI.
9. The method of claim 7 , wherein the network slice is changed at any time while the user equipment is registered with the PLMN.
10. A communication device, the communication device comprising:
one or more processor is configured to:
identify a S-NSSAI (single network slice selection assistance information) of a network slice for a network; and
select the network slice using the S-NSSAI,
wherein the network slice is logical network which provides a network capability and a network characteristic,
wherein the S-NSSAI includes a slice/service type (SST), which refers an expected behavior of the network slice in terms of a feature and a service and wherein the S-NSSAI includes a slice differentiator (SD) which complements a slice/service type.
11. The communication device of claim 10 , wherein the network slice is different from features and network functions optimization.
12. The communication device of claim 10 , wherein the network slice includes core network control plane and user plane network function.
13. The communication device of claim 10 , wherein a single user equipment is served with one or more network slice instances via an access network,
wherein the network slice instance is network function instance and a resource for the network slice.
14. The communication device of claim 13 , wherein a PDU(protocol data unit) session belongs to one network slice instance per PLMN(public land mobile network).
15. The communication device of claim 1 , wherein the S-NSSAI is included in subscription information, and is marked as default.
