Abstract: A session management method by a terminal in which a network initiates a session deactivation procedure to deactivate one or more sessions of a terminal. After the terminal in an inactive mode establishes an RRC connection to a new second base station, the second base station indicates, through RRC connection reconfiguration, the terminal to delete related information of the to-be-deactivated session, or the second base station uses an RRC connection resume response message to carry an identifier of the one or more to-be-deactivated sessions, and the terminal deletes session-related information corresponding to the identifier of the one or more to-be-deactivated sessions. In this way, the terminal is enabled to process the related information of the to-be-deactivated session in a timely manner.

Abstract: Embodiments of the present invention relate to a method for obtaining radio capability information of a terminal, a core network entity, a base station, and a terminal. When a first terminal changes from a first communication path for the first terminal to directly access a network to a second communication path for the first terminal to access the network by using a second terminal, the first terminal receives a first message that is sent by a base station to obtain radio capability information of the first terminal; and then sends the radio capability information of the first terminal to the base station, where the radio capability information includes information about a manner of connection between the first terminal and the second terminal and identification information of the second terminal.

Abstract: A method, user equipment (UE) and application server for adding media stream of multimedia session. A UE1 establishes a multimedia session with a UE2, receives a media stream adding request directed at the multimedia session of the UE1; the media stream adding request includes an identity of a UE3 and the media type of the media flow requested to be added; the UE3 is controlled to establish a media stream of the media type with the UE2. Therefore, adding the media stream on the UE3 is realized, and the user may realize the multimedia session with the peer end through multiple UEs, thereby avoiding the inconvenience that the media stream can only be added to the two parties in the session and living up to the users' diversified requirements on the multimedia services.
