  • Method and apparatus for processing terminal that is performing voice service, and communications system
    Patent number: 10587757
    Abstract: Embodiments of this application provide a method and an apparatus for processing a terminal that is performing a voice service, and a communications system. In the method, a RAN device actively redirects a voice service terminal, releases an RRC connection of the terminal, and instructs a CN device to retain a GBR bearer of the voice service terminal in a release process. Because a bearer type of a VOIP service is a GBR bearer, a bearer of the VOIP service is not released. When the terminal accesses a network again, the CN device may directly use the GBR bearer to restore the voice service, so as to avoid voice service interruption caused by releasing the bearer of the VOIP service in a redirection process, reduce a call drop rate, and improve user experience.
