Abstract: A communication method that includes: a terminal transmits data for a first application in a first communications system via a first protocol data unit (PDU) session, where the first PDU session does not support interworking between the first communications system and a second communications system. The terminal moves from the first communications system to the second communications system. After the terminal moves from the second communications system back to the first communications system, the terminal obtains a second PDU session based on at least first transmission information of the first application, and transmits data for the first application in the first communications system via the second PDU session, where the first transmission information includes an identifier of the first application.

Abstract: An inter-network change method and apparatus, where a terminal determines second network slice information to which first network slice information is mapped. The first network slice information is information about a first network slice accessed by the terminal, the second network slice information is information about a second network slice, the first network slice is a network slice in a first network, and the second network slice is a network slice in a second network. The terminal sends a request message to the second network and receives an accept message returned by the second network, such that the terminal accesses a network slice identified by network slice information accepted by the second network. It can be learned that embodiments of the present disclosure can implement a handover operation between network slices of different networks.

Abstract: An RRC connection release control method and an apparatus are applied to the field of mobile communication technologies and relate to the field of artificial intelligence (AI) and machine learning algorithms. When a first application of a terminal runs in a foreground, a timing duration of a first timer is set based on a timing duration corresponding to the first application, where the first timer starts when the terminal is in an RRC connected state, and when the terminal exchanges information with a network device, the first timer is reset, so as to control release of an RRC connection of the terminal based on the first timer.

Abstract: Embodiments of the present invention provide a service processing method and device. The service processing method includes: receiving a first message, where the first message includes first information of a first network slice, a priority corresponding to the first information, second information of a second network slice, and a priority corresponding to the second information; and preferentially processing a service of the high-priority network slice based on the priorities when a service of the first network slice collides with a service of the second network slice.

Abstract: This application discloses a communication method. When determining that a network used to provide a service does not meet a transmission requirement of service data, a terminal device requests, from a PCF, an SMF, or an NWADF, to analyze a reason why the network does not meet the transmission requirement of the service data. The PCF, the SMF, or the NWADF obtains information used to recover a service, and sends the information to a device that performs a service recovery operation, for example, the terminal device or an access network device. The information used to recover the service is used to enable the network to meet the transmission requirement of the service data.

Abstract: A first user equipment establishes a multimedia session with a second user equipment and receives a media stream adding request directed at the multimedia session of the first user equipment. The media stream adding request includes an identity of a third user equipment and the media type of the media flow requested to be added. The third user equipment is controlled to establish a media stream of the media type with the second user equipment.

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.
