In a CDMA framework, the accompanying parameters are characterized to distinguish a client and his area:

Ø MIN/IMSI

Ø MDN

Ø ESN

Ø TLDN

Ø SID/NID

Ø LAI

Ø GCI

Ø SIN

Ø SSN

MIN/IMSI:

IMSI is the main number to distinguish a portable client in a CDMA computerized open area cell versatile correspondence system. This code is substantial to all area including a wandering range. IMSI embraces E.212 coded framework. IMSI is put away in the versatile station/UIM card, HLR and VLR and transmitted on a remote interface and MAP interface. V PTCL utilizes MIN-based IMSI. IMSI is a 15-digit decimal number and its number structure is appeared in the figure.

MCC: Mobile Country Code, 410 for Pakistan.

MNC: Mobile Network Code 51 utilized as a part of V PTCL CDMA.

MSIN: Mobile Subscriber Identification Number, a 10-digit decimal number. PTCL requires that MIN is the last 10 digits of an IMSI, to be specific, MSIN.

SID/NID:

In a CDMA system, a versatile station judges whether wandering happens in light of a couple of character numbers (SID and NID). Framework Identity Number (SID) incorporates 15 bits. Unicom first uses 512 numbers (3600~37FF) with bit 14~bit 9 being 110010. Every nearby portable system is assigned with one SID and the particular number distributed to every neighborhood system is determined by Unicom central command. System Identity Number is comprised of 16 bits, with 0 and 65535 saved. 0 is utilized to speak to those base stations in a specific SID region not having a place with a particular NID range. 65535 is utilized to demonstrate that a versatile client can meander in the entire SID region. For a CDMA system side, there is no understanding of NID, yet a trade number (one byte), which is utilized to distinguish the system gear where a client is found.
