Abstract: Embodiments of this application disclose a slice service verification method and apparatus, to improve network security. The method in embodiments of this application includes: A slice service verification function entity receives a first message sent by a terminal device, where the first message carries an identifier of a first network slice and a first message authentication code, and the first message authentication code is calculated based on a first network identifier. The slice service verification function entity verifies the first message authentication code based on a second network identifier. The slice service verification function entity sends the second network identifier to an authentication server when the verification succeeds.

Abstract: This specification discloses a communication method, and a system. The method includes: receiving, by a first control network element, analysis information of a network data analytics network element NWDA, and generating a policy based on the analysis information; sending, by the first control network element, the policy to a second control network element, where execution of the policy is controlled by the second control network element; receiving, by the first control network element, an execution result of the policy that is sent by the second control network element, and determining, based on the execution result, whether the analysis information is invalid; and sending, by the first control network element, an invalidity notification message to the NWDA when the first control network element determines that the analysis information is invalid, where the invalidity notification message is used to instruct the NWDA to generate new analysis information.

Abstract: This application provides a parameter determining method and a communications entity. The method includes: When a UE is in a system in which an evolved packet system (EPS) network and a 5GS network interwork, the UE is currently located in the 5GS network, and QoS parameters used include an authorized UE aggregate maximum bit rate (AMBR) and an authorized session AMBR of a session. Because of movement of the UE, the UE needs to be handed over to the EPS network, and QoS parameters that need to be used for the UE in the EPS network include an authorized UE AMBR and an authorized access point name (APN) AMBR. The authorized APN AMBR is determined by a first communications entity based on at least one of a subscribed APN AMBR or the authorized session AMBR of the PDU session, and the authorized UE AMBR is determined by a second communications entity based on the authorized APN AMBR.

Abstract: Embodiments provide a location area management method, a control node, and user equipment (UE). The method is applied to a communications system including a control plane node, and the control plane node stores an upper-level area identity list of UE. The control plane node determines a lower-level area identity list of the UE based on the upper-level area identity list. The control plane node sends the lower-level area identity list to the UE. When the upper-level area identity list is allocated to the UE, the lower-level area identity list is allocated to the UE. The lower-level area identity list includes fewer areas than the upper-level area identity list, so that when the control plane node pages the UE, paging is performed in an area corresponding to the lower-level area identity list, thereby reducing signaling overheads of a network side device.
