WWAN_CDMA_MRL_INFO structure (wwan.h)

  • Article

The WWAN_CDMA_MRL_INFO structure represents information about a CDMA serving cell or neighboring cell.

Syntax

typedef struct _WWAN_CDMA_MRL_INFO {
  ULONG ServingCellFlag;
  ULONG NID;
  ULONG SID;
  ULONG BaseStationId;
  ULONG BaseLatitude;
  ULONG BaseLongitude;
  ULONG RefPn;
  ULONG GPSSeconds;
  ULONG PilotStrength;
} WWAN_CDMA_MRL_INFO, *PWWAN_CDMA_MRL_INFO;

Members

ServingCellFlag

Indicates whether this is a serving cell. A value of 1 indicates a serving cell, while a value of 0 indicates a neighboring cell. There may be more than one serving cell at a time (notably while in a call).

NID

The Network ID (0-65535). Use 0xFFFFFFFF when this information is not available.

SID

The System ID (0-32767). Use 0xFFFFFFFF when this information is not available.

BaseStationId

The Base Station ID (0-65535). Use 0xFFFFFFFF when this information is not available.

BaseLatitude

The Base Station Latitude (0-4194303). This is encoded in units of 0.25 seconds, expressed in two’s complement representation within the low 22 bits of the DWORD. As a signed value, North latitudes are positive. Use 0xFFFFFFFF when this information is not available.

BaseLongitude

The Base Station Longitude (0-8388607). This is encoded in units of 0.25 seconds, expressed in two’s complement representation within the low 23 bits of the DWORD. As a signed value, East longitudes are positive. Use 0xFFFFFFFF when this information is not available.

RefPn

The Base Station PN Number (0-511). Use 0xFFFFFFFF when this information is not available.

GPSSeconds

The GPS seconds, or the time at which this arrived from the base station. Use 0xFFFFFFFF when this information is not available.

PilotStrength

The Signal Strength of the pilot (0-63). Use 0xFFFFFFFF when this information is not available.

Remarks

WWAN_CDMA_MRL_INFO is designed for the CDMA2000 network type. There can be more than one CDMA2000 serving cell at the same time. Both serving cells and neighboring cells will be returned in the same list. The ServingCellFlag member indicates whether a cell is a serving cell or not.
