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.
