Detailed Description

This structure contains information about the GERAN Network.

Parameters
cellID
  • Cell ID.
  • 0xFFFFFFFF indicates cell ID information is not present.
plmn[NAS_PLMN_LENGTH]
  • MCC/MNC information coded as octet 3, 4, and 5.
  • This field is ignored when nmrCellID is not present.
lac
  • Location area code.
  • This field is ignored when nmrCellID is not present.
    • 0xFFFF - Not Available
arfcn
  • Absolute RF channel number.
    • 0xFFFF - Not Available
bsic
  • Base station identity code.
    • 0xFF - Not Available
timingAdvance
  • Measured delay (in bit periods; 1 bit period = 48/13 microsecond) of access burst transmission on RACH or PRACH to the expected signal from an MS at zero distance under static channel conditions.
    • 0xFFFFFFFF - Not Available
rxLev
  • Serving Cell Rx measurement.
  • Values range between 0 and 63.
  • Mapped to a measured signal level:
    • Rxlev 0 is a signal strength less than -110 dBm
    • Rxlev 1 is -110 dBm to -109 dBm
    • Rxlev 2 is -109 dBm to -108 dBm
    • ...
    • Rxlev 62 is -49 dBm to -48 dBm
    • Rxlev 63 is greater than -48 dBm
    • 0xFFFF - Not Available
nmrInst
  • Provides the number of set of instances which follow.
  • If 0(zero), then no information follows it.
