Abstract

A mobile communication network system includes a default network slice; at least one core network slice added according to a supporting service; andDeletedTextsat least one service operator network slice added according to a service operator in the core network slice. The core network slice is determined according to a service type required by user equipment, and the service operator network slice is determined by the core network slice.

Claims

1. A mobile communication network system comprising:

a default network slice;

at least one core network slice added according to a supporting service; and

at least one service operator network slice added according to a service operator in the core network slice,

wherein the core network slice is determined according to a service type required by user equipment, and the service operator network slice is determined by the core network slice.

2. The mobile communication network system of claim 1, wherein:

in a case where the user equipment requires a first service and a second service, a first core network slice according to a type of the first service and a second core network slice according to a type of the second service are configured.

3. The mobile communication network system of claim 1, wherein:

the default network slice determines a core network slice corresponding to a service type required by the user equipment among a plurality of core network slices, and

the core network slice determines a service operator network slice corresponding to the service type required by the user equipment among a plurality of service operator network slices.

4. The mobile communication network system of claim 1, wherein:

the default network slice performs a user equipment management function of authenticating whether a network access of the user equipment is allowed when the user equipment firstly accesses, a network slice selection function of selecting a network slice type to be used by the user equipment, and an authentication function of allocating an ID and an IP address to be used by the user equipment.

5. The mobile communication network system of claim 4, wherein:

the default network slice selects one core network slice from among a plurality of core network slices according to a service type required by the user equipment that accesses, determines a temporary ID with respect to the user equipment according to identification information of the selected core network slice, allocates an IP address to be used when the user equipment transmits a data packet, and transmits an access permission message to the user equipment.

6. The mobile communication network system of claim 5, wherein:

the access permission message includes identification information of the default network slice to which the user equipment is accessed, identification information of the selected core network slice, the temporary ID, the IP address, and authentication related information.

7. The mobile communication network system of claim 1, wherein:

the core network slice performs a user equipment management and authentication function of managing the user equipment that accesses and authenticating a service use authorization, and, in a case where the user equipment has the service use authorization, a network slice selection function of selecting one service operator network slice from a plurality of service operator network slices.

8. The mobile communication network system of claim 1, wherein:

the service operator network slice includes a specific control plane network function unit performing a session and QoS (Quality of Service) control and a specific user plane network function unit performing a data transfer.

9. The mobile communication network system of claim 8, wherein:

according to a data traffic path setting request of the core network slice for the user equipment, the specific control plane network function unit sets a data traffic path with the specific user plane network function unit based on location information of a base station to which the user equipment is accessed.

10. The mobile communication network system of claim 1, wherein:

a core network slice supporting the same service is changed according to a movement of the user equipment.

11. A control method of a mobile communication network system, the control method comprising:

a control device that is a default network slice of the mobile communication network system determining a network slice corresponding to a service type required by a user equipment; and

the control device transmitting a message including identification information of the selected network slice to the user equipment,

wherein the network slice includes a core network slice corresponding to the service type and further includes a service operator network slice in the core network slice.

12. The control method of claim 11, wherein:

the determining of the network slice includes,

the control device authenticating whether a user of the user equipment is a subscribed allowed to access; and

in a case where the user of the user equipment is the subscribed allowed to access, the control device selecting a core network slice corresponding to a service type required by the user equipment.

13. The control method of claim 12, wherein:

the transmitting of the message to the user equipment includes;

the control device determining a temporary ID of the user equipment according to identification information of the selected core network slice and allocating an IP address to be used when the user equipment transmits a data packet; and

the control device transmitting a message including identification information of the default network slice to which the user equipment is accessed, identification information of the selected core network slice, the temporary ID, the IP address, and authentication related information.

14. The control method of claim 13, further comprising:

before the determining of the network slice,

in a case where identification information of the user equipment that accesses is the temporary ID and the identification information of the default network slice provided from the user equipment is not identical to the identification information of the default network slice corresponding to the control device, the control device receiving a service request message with respect to the user equipment from the base station,

wherein a network slice with respect to the user equipment is re-determined.

15. A control method of a mobile communication network system, the control method comprising:

a control device corresponding to a core network slice of the mobile communication network system authenticating whether a user equipment has a service use authorization;

in a case where the user equipment has the service use authorization, the control device selecting one service operator network slice from a plurality of service operator network slices;

the control device requesting a data traffic path setting with respect to the user equipment from the selected service operator network slice; and

the control device transmitting information about a data traffic path set according to a request to the user equipment.

16. The control method of claim 15, wherein:

the service operator network slice includes a specific control plane network function unit performing a session and QoS control and a specific user plane network function unit performing a data transfer.

17. The control method of claim 16, wherein:

the requesting of the data traffic path setting includes;

the specific control plane network function unit of the service operator network slice receiving a data traffic path setting request;

the specific control plane network function unit selecting one specific user plane network function unit from a plurality of specific user plane network function units based on location information of a base station to which the user equipment is accessed; and

the specific control plane network function unit setting a data traffic path with the selected specific user plane network function unit.
