    Abstract: This application provides a network node selection method and apparatus. An SMF network element obtains transmission capability information of an access network device, and selects, for a terminal device based on the transmission capability information of the access network device, a UPF network element that supports at least one transmission capability included in the transmission capability information. In this process, the SMF network element obtains a transmission capability of the access network device, and selects the UPF network element based on the transmission capability of the access network device. The selected UPF network element supports the transmission capability used by the access network device, so that data can be successfully transmitted between the access network device and the UPF network element. Therefore, a data transmission success rate is improved.

    Abstract: A session establishment method and apparatus is provided, to resolve a problem that a terminal device cannot establish a plurality of PDU sessions for a same APP based on a URSP. The method includes: A terminal apparatus receives indication information from a first network apparatus, where the indication information is used to indicate that a first application needs to be associated with at least two sessions; and establishes at least one session for the first application based on at least the indication information, so that the first application is associated with at least two sessions.

    Abstract: The present disclosure relates to user plane information reporting methods and apparatus. In one example method, a session management network element obtains parameter information, and initiates establishment of a dedicated tunnel between a first communications apparatus and a second communications apparatus, where the parameter information indicates the first communications apparatus to report user plane information when a reporting condition is met. The session management network element sends a first rule to the first communications apparatus, where the first rule indicates the first communications apparatus to send a packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met.

    Abstract: An address obtaining method includes obtaining, by a third network device, an identifier of a first application from a terminal device. The identifier of the first application indicates a request for obtaining an address of an instance of the first application. The address obtaining method further includes sending, by the third network device, a first message to a first network device, wherein the first message comprises the identifier of the first application, and the first message is useable to request the address of the instance of the first application. The address obtaining method further includes receiving, by the third network device, the address of the instance of the first application from the first network device, and sending the address of the instance of the first application to the terminal device.

    Abstract: A method includes: User equipment determines whether confidentiality protection is activated for communication data between the user equipment and an application function device. The user equipment sends a user plane message to the application function device. The user plane message includes an identifier of the user equipment, and the identifier is an encrypted identifier in a case in which the confidentiality protection is inactivated.

    Abstract: This application provides a QoS flow control method and an apparatus. An SMF network element receives first indication information sent by an access network apparatus, where the first indication information is used to indicate that a first QoS target of a QoS flow cannot be met; and the SMF network element does not process the QoS flow if the SMF network element receives second indication information in a first preset time; or the SMF network element deletes or modifies the QoS flow if the SMF network element does not receive second indication information in a first preset time, where the second indication information is used to indicate that the first QoS target can be met.
