    • 0x00 - Invalid
    • 0x01 - Valid
    • 0xFF - Not Available
lac
  • Location area code.
  • Only applies to 3GPP.
    • 0xFFFF - Not Available
cellIdValid
  • Indicates whether the cell ID is valid.
    • 0x00 - Invalid
    • 0x01 - Valid
    • 0xFF - Not Available
cellId
  • Cell ID.
    • 0xFFFFFFFF - Not Available
regRejectInfoValid
  • Indicates whether the registration reject information is valid.
    • 0x00 - Invalid
    • 0x01 - Valid
    • 0xFF - Not Available
rejectSrvDomain
  • Type of service domain in which the registration is rejected.
    • 0x00 - SYS_SRV_DOMAIN_NO_SRV - No service
    • 0x01 - Circuit-switched only
    • 0x02 - Packet-switched only
    • 0x03 - Circuit-switched and packet-switched
    • 0x04 - Camped
    • 0xFF - Not Available
rejCause
  • Reject cause values sent are specified in [3GPP TS 24.008, Section 10.5.3.6 and 10.5.5.14]
