To address the question regarding the replacement of IMSI in the context of Air Interface, it is essential to understand the functions and roles of various identifiers in mobile networks.

The International Mobile Subscriber Identity (IMSI) is a unique identification number used to identify a subscriber in a mobile network. However, to enhance privacy and reduce signaling load, the IMSI is sometimes replaced by a temporary identity during communication, especially in visible areas.

In this context, the correct replacement for IMSI in VLR (Visitor Location Register) is:

**d. LMSI (Location Measurement Subscriber Identity)**

The LMSI is used as a temporary identifier that helps to protect the user's identity while allowing for effective network management. By using LMSI, the network can reduce the chances of unauthorized identification and improve overall user privacy.

### Summary:
IMSI is replaced by **LMSI** in VLR to minimize its usage in air interfaces, enhancing privacy and reducing signaling load.
