We study the location locking mechanism for H(e)NB in 3GPP TR 33.820. By now 3GPP has only proposed a few solutions for H(e)NB’s location locking in certain specific situations. In this paper, we propose an improved scheme for H(e)NB, which can be used for locking H(e)NB’s location in general situations. The scheme can deal with the security threats brought by unreliable location locking for H(e)NB in practical use. It also increases the reliability of H(e)NB’s location locking and increases the probability of locking successfully.
