step 101: the method comprises the steps that a first network device receives a slice service request from a second network device, and a matched first transmission resource slice is selected from a plurality of transmission resource slices configured in advance based on the slice service request;
step 102: and establishing a slice corresponding to the slice service request on the first transmission resource slice.
The slice selection method of this embodiment is applied to a first network device, which may be TN-NSSMF, for example, and a second network device which may be NSMF.
The first network device in this embodiment is configured to manage information related to transmission resource slices, and the first network device may store information related to a plurality of transmission resource slices. For example, the related information of the transmission resource slice may include an identifier corresponding to the transmission resource slice (e.g., an ID of the transmission resource slice); and/or, the information related to the transmission resource slice may include information related to a service type and/or a service characteristic corresponding to the transmission resource slice.
In this embodiment, the first network device may select a matched first transmission resource slice according to a slice service request issued by the second network device, and then establish a slice corresponding to the slice service request on the matched first transmission resource slice, that is, the slice requested by the slice service request needs to be established on an assigned transmission resource slice. The slice service request may also be referred to as a request, a service request, or the like, and the first transmission resource slice or transmission resource slice may also be referred to as a resource slice, a network resource slice, a slice, or the like, which is not limited in this embodiment.
In one embodiment, the slice service request includes a first transmission resource slice identifier; the selecting a matching first transmission resource slice from a plurality of pre-configured transmission resource slices based on the slice service request comprises: the first network device selects a first transmission resource slice from a plurality of pre-configured transmission resource slices that matches the first transmission resource slice identity.
In this embodiment, the slice service request includes a first transmission resource slice identifier corresponding to a requested transmission resource slice; the first network device searches whether a transmission resource slice corresponding to the first transmission resource slice identifier exists in the related information of the plurality of managed transmission resource slices, and selects a first transmission resource slice matched with the first transmission resource slice identifier if the first transmission resource slice corresponding to the first transmission resource slice identifier exists.
In another embodiment, the selecting a matching first transmission resource slice from a plurality of pre-configured transmission resource slices based on the slice service request includes: and the first network equipment determines service characteristics based on the service information in the slice service request, and selects a first transmission resource slice matched with the service characteristics from a plurality of transmission resource slices configured in advance.

and the first network equipment sends the slice information corresponding to the transmission resource slice identifier to the second network equipment.
7. The method according to any one of claims 1 to 3, further comprising:
and if the first network equipment does not find the matched first transmission resource slice from the plurality of transmission resource slices configured in advance, sending slice creation failure information to the second network equipment.
8. The method of claim 1, wherein the preconfigured plurality of transmission resource slices are configured to meet multiple types of traffic demands.
9. The method of claim 1, wherein the preconfigured plurality of transmission resource slices comprises a transmission resource slice for a particular user.
10. A slice selection apparatus, the apparatus comprising: the device comprises a receiving unit, a slice selecting unit and a slice establishing unit; wherein, the first and the second end of the pipe are connected with each other,
the receiving unit is used for receiving a slicing service request from a second network device;
the slice selection unit is used for selecting a matched first transmission resource slice from a plurality of transmission resource slices configured in advance based on the slice service request;
the slice establishing unit is configured to establish a slice corresponding to the slice service request on the first transmission resource slice.
11. The apparatus of claim 10, wherein the slice service request comprises a first transmission resource slice identifier;
the slice selection unit is configured to select a first transmission resource slice matching the first transmission resource slice identifier from a plurality of pre-configured transmission resource slices.
12. The apparatus of claim 10, wherein the slice selecting unit is configured to determine a traffic feature based on the traffic information in the slice traffic request, and select a first transmission resource slice from a plurality of pre-configured transmission resource slices, the first transmission resource slice matching the traffic feature.
13. The apparatus of claim 10, further comprising an acquisition unit and a transmission unit; wherein, the first and the second end of the pipe are connected with each other,
the acquisition unit is used for acquiring slice information corresponding to a pre-configured transmission resource slice; the slice information at least comprises a transmission resource slice identifier corresponding to the transmission resource slice;
the sending unit is configured to send the slice information to the second network device.
14. The apparatus of claim 13, wherein the sending unit is further configured to send the updated slice information to the second network device when it is determined that the slice information is changed.
15. The apparatus according to claim 13, wherein the receiving unit is further configured to receive an inquiry request from the second network device, where the inquiry request includes a transmission resource slice identifier;
the sending unit is further configured to send slice information corresponding to the transmission resource slice identifier to the second network device.
16. The apparatus according to any of claims 10 to 12, wherein the sending unit is further configured to send slice creation failure information to the second network device if a matching first transmission resource slice is not found from a plurality of pre-configured transmission resource slices.
17. The apparatus of claim 10, wherein the preconfigured plurality of transmission resource slices are configured to satisfy multiple types of traffic demands.
18. The apparatus of claim 10, wherein the preconfigured plurality of transmission resource slices comprises a transmission resource slice for a particular user.
19. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 9.
20. A network device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the steps of the method of any of claims 1 to 9 are implemented when the processor executes the program.
