Embodiment Construction

[0087] Network slicing, namely "5G slicing", supports a communication service of a specific connection type, and provides control plane (English: Control Plane, abbreviated: CP) and user plane (English: User Plane, abbreviated: UP) specific processing method. In order to achieve this goal, mobile operators realize the configuration and management of hundreds of thousands of network slices through the configuration and arrangement of a series of network functions on the control platform of the core network (English: core network, CN for short), so as to support specific use case or business model. Network slicing can involve a series of configuration and support of end-to-end network elements, including user equipment (English: user equipment, referred to as: UE) end, access network (English: radio access network, referred to as: RAN) and other equipment . Network slicing can be used to support specific applications and business models, provide only necessary business process...

Abstract

The present application discloses a network slice selection method and device, which are used to solve the problem of heavy transmission burden on the network side in the prior art. The method includes: the core network device receives a first request message sent by the terminal device, the first request message is used to request the terminal device to allocate a network slice that provides business services; the core network device selects a network slice for the slice. The functional entity SSF sends a query message, the query message carries the user information of the terminal device, and is used to query the network slice that can provide business services for the terminal device; the core network device receives the information sent by the SSF based on the After the slice information of the network slice that can provide the business service required by the terminal device is determined by the user information, the first request message is forwarded to the network slice corresponding to the slice information, so that the network slice corresponding to the slice information The slice provides business services for the terminal device.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for selecting network slices. Background technique [0002] With the continuous enhancement of network communication connection capabilities, almost every industry is undergoing digital transformation to improve work and production efficiency. For example, virtual meetings and classrooms based on holographic technology; remote real-time control of large machinery in dangerous environments, remote surgery; mobile broadband in high-speed mobile vehicles; ubiquitous Internet of Things, ubiquitous mobile video; real-time industrial control and so on. The demands of digital transformation for connectivity capabilities are constantly increasing and diversifying. Different use cases have very different requirements for network speed, performance, security, reliability, and delay. Therefore, the traditional single network is gradually unable to...
