Abstract
A handover method for supporting terminal mobility is provided, wherein, before a target core network node updates bearer information, an access control determination procedure is added. According to the access control determination information provided by the target base station, if it is determined that the bearer supporting a SIPTO or LIPA service is permitted to perform the handover, the target core network node updates the bearer information. If it is determined that the bearer supporting the SIPTO or LIPA service is not allowed to perform the handover, the handover failure is notified as per the bearer not performing the handover, and the bearer information is not updated. Alternatively, during or after the handover to the target network, the bearer release or deactivation is performed for the bearer not performing the handover, so that the UE may re-initiate the bearer establishment process with respect to the bearer not performing the handover.
