摘要： Embodiments of this application provide a session management method, apparatus, and system. The method includes: receiving, by a first session management network element, a session request message from a second session management network element; allocating, by the first session management network element, Internet protocol IP information of a terminal device to a first session based on the session request message, where the first session is a branch of an established second session; and sending, by the first session management network element, the IP information of the terminal device to the second session management network element, where the IP information is used to obtain policy information corresponding to the IP information.

摘要： A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.

摘要： A data processing method includes obtaining, by a session management function (SMF) network element from an external network element, a media access control (MAC) address of a terminal device and an Internet Protocol (IP) address corresponding to the MAC address, and sending, by the SMF network element, the MAC address and the IP address to a first user plane function (UPF) network element, where the MAC address and the IP address are used to send an Address Resolution Protocol (ARP) message, and the ARP message includes the MAC address and the IP address.

摘要： Embodiments of this application provide a method for selecting an access network type, a device, and a system, to flexibly select an access network type. An example method includes: determining, by a policy control function PCF entity, that a network status of a first network does not meet a preset condition, where the first network is a network currently accessed by a terminal; and sending, by the PCF entity, an access network type corresponding to a second network to the terminal, where the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.
