[0187] See Figure 4 , The figure shows the process of selecting network slices and attaching network slices. The specific steps are as follows:

[0188] Step 401: The terminal (UE) sends an attachment request to the radio access network (RAN);

[0189] In the attach request, the UE sends network slice selection assistance parameters to the base station in the RAN, where the network slice selection assistance parameters include but are not limited to network slice identification (Slice-ID), service type, and so on.

[0190] Specifically, the UE initiates an attach request to the RAN side, which includes information such as an attach request message (Attach Request Message) and RRC (Radio Resource Control, radio resource control) parameters. Among them, the RRC parameters include network slice selection assistance parameters, such as Slice-ID information, service type, etc.

[0191] The above-mentioned network slice identification can include two parts, one part is the network slice ty...

Abstract

The embodiment of the invention provides a network slice selection method, device and network architecture, and the technical problem that a network slice cannot be flexibly selected in the prior artis solved. The method includes the steps of using a slice selection control function to acquire one or more items of a slice selection strategy, user subscription information, network slice selectionassistance parameters and the user context; the slice selection control function determining network slice selection information according to the one or more items of the slice selection strategy, user subscription information, network slice selection assistance parameters and the user context, sending the determined network slice selection information to the slice routing function, so as to enable the slicing routing function to execute signaling or data routing (signaling is 5G control signaling), and the data is sent by a user, such as internet surfing data, internet of things data and thelike ). The technical problem that a network slice cannot be flexibly selected in the prior art can be solved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and network architecture for network slice selection. Background technique [0002] Mobile networks need to meet more diverse business scenarios, such as low-power consumption and large connections, high-capacity hotspots, continuous wide-area coverage, low latency and high reliability. At present, mobile networks are based on a set of logical architectures to serve various application scenarios. Although the MME (Mobility Management Entity) has certain intelligent capabilities, it can select a gateway based on the user's subscription and service identification. The base station has a weight that can select the MME based on the MME load. However, this solution is difficult to adapt to various business scenarios in future networks (such as the Internet of Things, low latency, etc.). Its architecture is single and inflexible, making it difficul...
