Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In scenarios where a terminal device subscribes to multiple network slices, existing technologies cannot effectively select a suitable network slice for the terminal device based solely on subscription information.

Innovation Solution

A method where the terminal device generates and sends information such as service information and access information to the network device, allowing it to select an appropriate network slice, which may include preconfiguring a unique network slice identifier or using information about the service initiated by the terminal device to determine the network slice.

1Device complexity

If the network device selects a network slice based only on subscription information, then the selection process is simple, but the network device cannot select a suitable network slice when the terminal device subscribes to multiple network slices

Engineering Contradiction:

Improvenetwork slice selection processVSAvoidnetwork slice selection capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The terminal device performs preliminary action by generating first information (including service information, access information, and network slice information) before the network device makes its selection. This preliminary information generation enables the network device to accurately select from multiple subscribed network slices based on actual service needs rather than just subscription status.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first information generated by the terminal device acts as an intermediary between the terminal's subscription status and the network device's selection decision. This intermediary information bridge enables the network device to make informed selections among multiple network slices by considering service requirements and access conditions, not just subscription information.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the terminal device provides detailed first information (service information, access information, network slice information) to the network device, then the network device can accurately select a suitable network slice, but the information transmission and processing complexity increases

Engineering Contradiction:

Improvenetwork slice selection accuracyVSAvoidinformation processing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The first information is segmented into distinct components: service information (identifying the service type), access information (describing access conditions), and network slice information (identifying subscribed slices). This segmentation allows the network device to process and evaluate each aspect systematically, improving selection accuracy while managing processing complexity through structured information organization.

AI summary

A network slice selection method is provided, so that in a scenario in which one terminal device subscribes to a plurality of network slices, a network device can select a network slice for the terminal device. The method includes: a terminal device sends a first message to a network device, wherein the first message is used to request to select a network slice for the terminal device. Then the terminal device receives a second message sent by the network device, wherein the second message is used to indicate a network slice selected by the network device for the terminal device.
