Abstract: This application discloses a data analysis method and an apparatus. The method includes: A data analysis network element sends a first request message to a security network element, where the first request message is used to request to perform security detection on first data, and the first data is data for which the data analysis network element performs data analysis on a specified data analysis type. The data analysis network element generates or updates, based on a security detection result, a data analysis result corresponding to the data analysis type. According to the method in this application, the security network element may perform security detection on the first data, and separate abnormal data from the first data, so that the data analysis network element can establish a model based on data other than the abnormal data, to improve accuracy of the model and improve accuracy of the data analysis result.

Abstract: An inter-network interworking method, an apparatus, and a system are provided, and relate to the field of communication technologies, to ensure that a service is not interrupted when a terminal moves from a second network to a third network. The method includes: When the terminal supports a NAS capability of the third network and/or a network name corresponding to the terminal supports interworking between the second network and the third network, a second access management network element sends a session management request including a session identifier to a first session management network element that supports interworking of the terminal among a first network, the second network, and the third network. The second access management network element receives, from the first session management network element, a session management response including a session context of the terminal in the third network. According to the method, the session context of the terminal in the third network can be prepared in advance when the terminal accesses the second network, so that it is ensured that the service is not interrupted when the terminal subsequently moves from the second network to the third network.

Abstract: Embodiments of this application provide a slice information processing method and apparatus to preferentially allocate a network slice resource to a slice for which a slice service level agreement SLA has been signed. An example solution includes: An access network device determines that a slice service level agreement (SLA) has been signed for a first slice and that no slice SLA has been signed for a second slice. The access network device prioritizes a user behavior action of the first slice, or deprioritizes a user behavior action of the second slice.

Abstract: Embodiments of this application disclose a service establishment method and a device. The method includes: an access network device receives an establishment request from a core network device or a service application server, where the request carries a requirement of a to-be-established service. When determining that radio channel quality of a first cell of a first network in which the UE is located does not meet the requirement of the service, the access network device sends an establishment response to the core network device or the server, where the response notifies the core network device or the server that the radio channel quality of the first cell does not meet the requirement; or the access network device hands over the UE to a second cell of the first network; or the access network device hands over the UE to a third cell of a second network.
