Abstract: A communication method and apparatus for a user terminal provided in the present invention can detect the user terminal, obtain first capability information on a video communication of a wireless network, and second capability information on the video communication of said user terminal, process the first capability information and the second capability information to generate video communication capability indication information, and select one of operations to perform according to said video communication capability indication information, said operations including enabling a video session or enabling the video session after closing at least a part of applications being used by said user terminal or enabling an audio session. Such a processing scheme of the communication for a user terminal is of high efficiency, with a clear process and can be easily optimized, with an improved success rate for establishing a video session at a time.

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.
