Abstract: 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.

Abstract: Methods, systems, and apparatus for clock synchronization are provided. In one aspect, a clock synchronization method includes: receiving, by a terminal and from an access network device, information about N clock domains, determining, by the terminal, M clock domains that are associated with the terminal and that are in the N clock domains, and separately performing, by the terminal, clock synchronization with clock sources of the M clock domains based on information about the M clock domains. Information about a clock domain includes first time information and a clock domain number of the clock domain. The first time information includes a time of a clock source of the clock domain when the access network device sends the information about the clock domain. The clock domain number identifies the clock domain. N is an integer greater than 1, and M is an integer greater than 1.

Abstract: A service transmission method and apparatus are provided to establish a connection between an access and mobility management function network element and a secondary base station, when a master base station is not capable of continuing to provide a service for a terminal device. In an embodiment, an access and mobility management function network element determines that a master base station is not capable of continuing to provide a service for a terminal device. The access and mobility management function network element sends a mobility management context of the terminal device to a secondary base station, where the mobility management context is used by the secondary base station to perform mobility management on the terminal device. Therefore, a signaling connection between the access and mobility management function network element and the secondary base station can be quickly established, thereby ensuring service transmission and improving user experience.

Abstract: This application discloses a network slice management method and a device that is designed to improve network slice deployment efficiency. In the network slice management method, after obtaining indication information of a network slice template and performance requirement information of a target network slice, a first network management device may determine deployment information of the target network slice based on the two pieces of information, and may manage the target network slice based on the deployment information of the target network slice, without manual involvement. Therefore, network slice deployment efficiency can be improved.

Abstract: 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.

Abstract: The present disclosure relates to communication methods, core network devices, and access network devices. One example method includes receiving, by a core network device, a first message from an access network device, where the first message carries information used to indicate a slice supported by the access network device, and determining, by the core network device, a location area identity list of user equipment UE based on the information used to indicate the slice supported by the access network device.

Abstract: This application provides a data transmission method and communications devices. In some implementations, a first device instructs a second device to stop sending data of an application to the first device, receives from the second device first indication information indicating a sequence number of data that is of the application and that has been received by the second device from the first device, and sends to the second device second indication information indicating a sequence number of data that is of the application and that has been received by the first device from the second device. After a connection between the terminal device and a second server is established, the first and second indication information are used to transmit the data of the application through the connection.

Abstract: A method and a device for performing communication by using a virtual subscriber identity module are used to provide a mode in which the device can perform communication without a SIM card. The method includes: receiving, by a first device, a virtual subscriber identity module data package sent by a second device by using a short range communications protocol, where the virtual subscriber identity module data package carries a virtual subscriber identity, and the virtual subscriber identity is used to uniquely identify a user using the first device when the first device performs communication in a network provided by a mobile communications operator; obtaining, by the first device, the virtual subscriber identity by using the virtual subscriber identity module data package; and communicating, by the first device by using the virtual subscriber identity, with another device in the network provided by the mobile communications operator.
