UTRAN Cell Identity returned by getCid()

Question

In UMTS I get a large number returned by getCid() (larger than the allowed value). Is this the UTRAN Cell Identity (UC-ID)?

UC-Id = RNC-Id + C-Id
         


        

Answer 1

This is more simple than this. Cell ID is in the low register of the value getCid() returns, the RNC is the high register of this value (http://developer.android.com/reference/android/telephony/gsm/GsmCellLocation.html#getCid()). So:

getCid() == RNC << 16 | CID

CID = getCid() & 0xffff

RNC = (getCid() >> 16) & 0xffff
