A method for user relocation triggered by a Home NodeB Gateway (HGW) is provided, which comprises steps of: transmitting, by the HGW, a relocation request message to a Home NodeB (HNB) to which a User Equipment (UE) belongs; triggering, by the HNB, a relocation procedure to relocate the UE to another NodeB; and transmitting, by the HNB, a relocation response message corresponding to the relocation request message to the HGW. With the present invention, it is possible in a HNB system to implement a UE relocation triggered by a HGW for new scenarios. This scheme enhances the Iu-h interface and facilitates the improvement of service quality of users. Additionally, it is capable of providing users with continuous services in different scenarios. The present method is easy to implement and effective in improving the stability and performance of HNB system.
