Abstract
The present invention discloses a method for controlling switch of multi-mode mobile user equipment (UE). Through designing a dedicated Switch Control Module (SCM) in the existing terminal management module within the multi-mode UE supporting IMS services, utilizing the automatic detection function of the Access Service Network (ASN) at the terminal side, and modifying part of the control signaling of the Connectivity Service Network (CSN) at the terminal side to make the UE participate the switch control procedure actively, the invention implements the seamless switch between different networks, strengthening the real-time performance during the network switch, thus enabling the mobile multimedia service to continue to satisfy the requirements for the real-time performance even when switched in use and enabling the user to obtain quicker data transmission rate, better quality of service and service with a cheaper price.
