摘要
The disclosure discloses a method for tracking an International Mobile Equipment Identity (IMEI) of User Equipment (UE), which includes: obtaining, by a Radio Network Controller (RNC), an IMEI of UE from an identity response message, which is sent by the UE to respond a non-access stratum identity request message, after success of signalling connection of a UE call when the RNC establishes Radio Resource Control (RRC) connection with the UE (S11); and saving, by the RNC, the obtained IMEI in a user log generated in a process of the UE call (S12). The disclosure further discloses a RNC for tracking an IMEI of UE. The method and the RNC of the disclosure can solve the problem that a RNC cannot obtain IMEI information directly, so that a network operation and maintenance analysis system can track the IMEI according to a UE call log to reflect specific details of each call of different types of terminal equipments, and perform statistical analysis on the key performance indicator based on terminal type grouping.
