Title
(EN) Method and system for controlling network access during HNB handover
Abstract
(EN)

The present invention discloses a method and a system for controlling network access during HNB handover. The method comprises the following steps: a core network acquires target HNB information to determine whether to allow access of User Equipment (UE) and sends the target HNB information to an HNB GW to which the target HNB belongs if the access of the UE is allowed and the target HNB is connected with the core network via the HNB GW, and the HNB GW determines whether to allow the access of the UE according to the received target HNB information. The present invention can prevent the occurrence of illegal accesses and improve the security of network access.
