WWAN_SINGLE_NSSAI structure (wwan.h)

  • Article

The WWAN_SINGLE_NSSAI structure represents a single Network Slice Selection Assistance Information (NSSAI). WWAN_SINGLE_NSSAI is used to uniquely identify a network slice.

Syntax

typedef struct _WWAN_SINGLE_NSSAI {
  UINT32 Bitmasks;
  UINT16 SliceServiceType;
  UINT16 MappedSliceServiceType;
  UINT32 SliceDifferentiator;
  UINT32 MappedSliceDifferentiator;
} WWAN_SINGLE_NSSAI, *PWWAN_SINGLE_NSSAI;

Members

Bitmasks

A 32-bit integer containing the map (logical OR) indicating if the fields that follow are present.

SliceServiceType

Only valid if Bitmasks contains WWAN_SNSSAI_SST_VALID (0x00000001).

MappedSliceServiceType

Only valid if Bitmasks contains WWAN_SNSSAI_MAPPED_SST_VALID (0x00000002).

SliceDifferentiator

Only valid if SliceServiceType is valid. May be WWAN_SNSSAI_NO_SD_VALUE_ASSOCIATED_WITH_SST (0x00FFFFFF).

Defines the expected behavior of the network slice features and services. Values include enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive Internet of Things (MIoT).

MappedSliceDifferentiator

Only valid if MappedSliceServiceType is valid. May be WWAN_SNSSAI_NO_SD_VALUE_ASSOCIATED_WITH_SST (0x00FFFFFF).

The slice differentiator is directly related to the SliceServiceType and is used as an additional differentiator if multiple network slices carry the same value in SliceServiceType.
