- UIMID
UIMID (User Identity Module Identifier) is an
Electronic Serial Number (ESN) stored in a R-UIM ('smart card') used for TDMA orCDMA2000 phones (mainly the latter). It is given a different name to avoid confusion with the hardware ESN stored in the phone. In all known systems the UIMID displaces the ESN in signaling (based on the 'UsgInd' field stored in the R-UIM). Because the UIMID is allocated from the same numbering space as ESN this is transparent to the network. The reason the UIMID is transmitted instead of the ESN is because the R-UIM contains the MIN or IMSI and devices such as the HLR running theANSI-41 mobility management protocol insist on a static association between these identifiers. The HLR will store the MIN or IMSI alongside the ESN in each record, and if an ANSI-41 message is received containing a different pair it will be rejected.UIMID codes are allocated by the TIA using industry-defined guidelines and with codes that have been transferred from the ESN administrator (also the TIA).
