In a CDMA system, the following parameters are

defined to identify a user and his location:

MIN/IMSI

MDN

ESN

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).
