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: Embodiments of the present disclosure provide a management method, and a management device and a system that are based on the method. The method includes: sending, by a second management device, an update request to a first management device, where the update request is used to request the first management device to update requirement information of a subnet managed by the first management device; and then, determining, by the first management device, that the subnet can satisfy the update request, or determining that the subnet cannot satisfy the update request. In the solutions in the embodiments of the present disclosure, the second management device can request the first management device to update the requirement information of the subnet managed by the first management device, thereby preventing a management fault of an entire network slice when a subnet managed by the second management device cannot satisfy a preset requirement.
