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.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, an apparatus, and a system for establishing a session, to resolve a problem in the prior art that efficiency is low because an AMF entity needs to reselect an SMF entity when forwarding a first message. The method includes: receiving, by a mobility management function AMF entity, a first message sent by user equipment UE, where the first message carries identifier information, the identifier information is used to instruct the AMF entity to send the first message to a session management function SMF entity, and the first message is used to instruct the SMF entity to re-establish a session with the UE based on the identifier information by using a first user plane function UPF entity; and sending, by the AMF entity based on the identifier information, the first message to the SMF entity associated with the identifier information. The embodiments of the present invention are applied to a system for establishing a session.

Abstract: This application discloses a network access method and device. The method includes: receiving, by a first management entity, a first request message sent by a first terminal, where the first request message includes at least a first identifier of a second terminal; determining, by the first management entity based on a first condition, whether the second terminal can access a network by using the first terminal, where the first condition includes at least that the first identifier of the second terminal belongs to a list of at least one terminal having a trust relationship with the first terminal, and the list includes at least a first identifier of the at least one terminal having the trust relationship with the first terminal. Legality of access by a wearable device to a network by using a user terminal can be authenticated by using the method and device in this application.
