ESN
A unique Electronic Serial Number (ESN) is used to identify single
MS. An ESN includes 32 bits and has the following structure:
31......24 23......18 17......0 bit
Manufacturer’s number retained equipment SN
For example, FD 03 78 0A (the 10th Motorola 378 mobile phone)
The equipment serial number is allocated by a manufacturer.

SID/NID
In the CDMA network, the MS determines whether roaming occurs by a pair of IDs (SID and NID).
The system ID (SID) contains 15 bits.
Each mobile local network is allocated with one SID.
The network ID(NID) contains 16 bits. This concept just used in the BSS side.

MSCID
MSCID
= System Identity (SID) + Switch number (SWIN)
is used to represent a certain set of equipment in an NSS
network. For example,
Unicom CDMA Shenzhen MSC is labeled as 3755+01
USA CDMA MSC is 4477+01

Location Area Identity (LAI)
PAGING message is broadcast within a local area, the size of which
depends on traffic, paging bearer capability, signaling flow , etc.
Format: MCC+MNC+LAC
MCC: Mobile Country Code, 3 digits. For example, China is
460.
MNC: Mobile Network Code, 2 digits. For example, the MNC of
Unicom is 03.
LAC: Location Area Code, a 2-byte-long hexadecimal BCD
code.
For example, 460030100(CHN) / 310010001(USA)

Global Cell Identity (GCI)
The unique ID of a cell in PLMN
Format: LAI+CI
CI: Cell Identity, a 2-byte-long hexadecimal BCD code, pre
defined by the engineering department. The first 3 digits and
the last digit represent the base station number and the sector
number respectively. For an omni-directional site, the last digit
of CI is 0.
For example, 4600301001230 shows base station number 123
contains an omni-directional site.
3100100010010(USA).
