Re: Cell ID
3G / UMTS
Normally, Location Area Code (LAC) will be used with Cell ID which have 2 types.
So it's very confuse to us.
Long Cell ID or UTRAN Cell ID (28 bits) = Radio Network Controller ID (12 bits) + Short Cell ID (16 bits)
Example:
RNC = RNC ID = 365
CID = Short Cell ID = 5486
LCID = UTRAN Cell ID = 23926126 = (365 x 65536) + 5486

Normally, Tracking Area Code (TAC) will be used with Long Cell ID.
Long Cell ID or E-UTRAN Cell ID (28 bits) = eNodeB ID (20 bits) + Short Cell ID (8 bits)
Example:
eNBI = eNodeB ID = 1630
CLID = Short Cell ID = 2
ECI = E-UTRAN Cell ID = 417282 = (1630 x 256) + 2
Can be written as the pattern = 1630.2
