Abstract: Embodiments of this application provide a roaming method. The method includes: A terminal device obtains information about a first PLMN, where a dynamic roaming agreement exists between the first PLMN and a second PLMN. If the terminal device cannot access the second PLMN, the terminal device sends an access request to the first PLMN based on the information about the first PLMN. The dynamic roaming agreement exists between the first PLMN and the second PLMN.

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 UE policy obtaining method includes receiving, by a first PCF network element in a VPLMN, a first URSP of an HPLMN that includes a first rule from a second PCF network element in the HPLMN, and sending, to a UE, a second URSP of the VPLMN that includes a second rule and a third rule. The first rule is used to indicate an association between first S-NSSAI, a first application, and a first DNN, the first DNN being used to identify a first DN, and the first DN allowing LBO and supporting the first application and a second application. The second rule is used to indicate an association between second S-NSSAI, the first application, and the first DNN. The third rule is used to indicate an association between the second S-NSSAI, the second application, and the first DNN.

Abstract: A domain name system query method in which: a first network element receives a DNS query request including a first domain name from a terminal apparatus; the first network element sends first request information which comprises location information of the terminal apparatus and the first domain name to a second network element; the second network element determines, based on the first request information, an IP address and feeds back the IP address to the first network element; and the first network element sends the IP address to the terminal apparatus. When a terminal apparatus performs domain name query, a core network element determines an IP address of an application server based on location information of the terminal apparatus and a queried domain name. In this way, the terminal apparatus obtains an IP address of an application server close to the terminal apparatus, thereby improving service access efficiency of the terminal apparatus.

Abstract: A clock source determining method and an apparatus are provided. The method includes: A session management network element receives a session request from a mobility management network element. The session request includes information about a network slice and a DNN, and the session request is used to request to create a session. The session management network element determines clock source information corresponding to both the information about the network slice and the DNN. The session management network element sends the clock source information to an access network device. The clock source information is used by the access network device to perform clock synchronization with a terminal device.

Abstract: Disclosed is an AMBR control method, device, and system, so that a quality of service (QoS) control mechanism can be used to control use of resources in a network slice by a terminal device. The method includes: a mobility management network element obtaining M pieces of single network slice selection assistance information (S-NSSAI) corresponding to a terminal device and a first slice-AMBR corresponding to each piece of S-NSSAI in the M pieces of S-NSSAI; and sending the M pieces of S-NSSAI and the first slice-AMBR corresponding to each piece of S-NSSAI to an access network device, where the first slice-AMBR corresponding to each piece of S-NSSAI is used to determine a second slice-AMBR corresponding to the S-NSSAI, and the second slice-AMBR corresponding to each piece of S-NSSAI is used to control an aggregate bit rate of non-guaranteed bit rate non-GBR QoS flows in a network slice indicated by the S-NSSAI.

Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.
