## Abstract

Systems and methods described herein provide new parameters for RAN configurations to manage network slices. A network device stores definitions for multiple mode parameters for a central unit (CU) of a radio access network (RAN), wherein each mode parameter defines a section of the CU that provides a relative performance level for a slice subnet over the RAN. The network device receives a slice configuration request for a network slice that identifies one of the multiple mode parameters and instantiates the network slice to operate over the section of the CU that is associated with the identified one of the multiple mode parameters. Additionally, a slice anti-affinity (SA) parameter is provided to selectively isolate network slices and improve slice reliability within the RAN.

## Claims

### Claim 1

storing definitions for multiple mode parameters for a central unit (CU) of a radio access network (RAN), wherein each mode parameter defines a section of the CU that provides a relative performance level for a slice subnet over the RAN;

instantiating the network slice to operate over the section of the CU that is associated with the identified one of the multiple mode parameters.

### Claim 2 (depends on 1)

### Claim 6 (depends on 1)

The method of claim 1, wherein the identified one of the multiple mode parameters provides reduced performance, relative to a designed slice performance, for the network slice over the slice subnet.

### Claim 7 (depends on 1)

The method of claim 1, wherein the identified one of the multiple mode parameters provides improved performance, relative to a designed slice performance, for the network slice over the slice subnet.

### Claim 8 (depends on 1)
