Note: A GSM Cell ID (CID) is a generally unique number used to identify each base transceiver station (BTS) or sector of
a BTS within a Location area code (LAC) if not within a GSM network. Please refer to the following description for details
in each item.
Tail Report Item
Description
R27
RSSI. The Received Signal Strength Indication of GSM network. Ranges from R0 to R31.
R99 means service unavailable.
Vibration Status (Move/Stop State):
M
Vibration Sensor OFF (VS Off)

MCC466
Mobile Country Code. MCC is defined in ITU-T E.212 for use in identifying mobile stations in
GSM networks of which country.
MNC97
Mobile Network Code. MNC is used in combination with MCC to uniquely identify a mobile
phone operator/carrier using the GSM networks and some satellite mobile networks.
LAC51145
Location Area Code. A "location area" is a set of base stations that are grouped together to
optimize signaling. Typically, tens or even hundreds of base stations share a single Base
Station Controller (BSC) in GSM, the intelligence behind the base stations.
To each location area, a unique number called a "location area code" is assigned. The
location area code is broadcast by each base station, known as a "base transceiver station"
BTS in GSM at regular intervals.
CID16012
Cell Identity. For BTS identification.
