Solution Overview

Problem

Existing communication methods require a centralized network management device to manage terminal device access to network slices, leading to increased network complexity and latency.

Innovation Solution

A communication method where a terminal device autonomously selects and accesses a target network slice using locally-stored access configuration information, eliminating the need for a network management device to reduce complexity and latency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized network management device is used to manage terminal device access to network slices, then network access control and management capability is improved, but network complexity increases and access latency increases

Engineering Contradiction:
Improvenetwork access control capabilityVSAvoidnetwork complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the network slice selection function from the centralized network management device and implements it locally in the terminal device. The terminal device autonomously selects network slices based on stored configuration information, eliminating the need for centralized management intervention in the selection process, thereby reducing network complexity while maintaining access control capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The terminal device is empowered to perform self-service by autonomously selecting network slices based on pre-stored configuration information. This self-service mechanism eliminates dependency on centralized management devices for slice selection, reducing both network complexity and access latency while maintaining reliable network access control

Inventive Principle:
Principle #25Self-service

2Reliability

If a centralized network management device is used to manage terminal device access to network slices, then network access control capability is improved, but access latency increases

Engineering Contradiction:
Improvenetwork access control capabilityVSAvoidaccess latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-storing network slice configuration information in the terminal device before access is needed. When the terminal device needs to access a network slice, it can immediately select from pre-configured options without waiting for centralized management device responses, significantly reducing access latency while maintaining control capability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal device performs self-service by autonomously selecting network slices based on pre-stored configuration information, eliminating the time delay associated with centralized management device communication. This self-service mechanism reduces access latency while maintaining reliable network access control

Inventive Principle:
Principle #25Self-service

AI summary

This application provides a communication method and a communications apparatus. The communication method includes: receiving a first message from a shared channel of a plurality of network slices, where the first message includes a plurality of network IDs, and the plurality of network IDs are in a one-to-one correspondence with the plurality of network slices; selecting a target network slice from the plurality of network slices; and obtaining access configuration information of the target network slice from network configuration information, and accessing the target network slice based on the access configuration information of the target network slice, where the network configuration information includes a network ID of each of the plurality of network slices and the access configuration information of the target network slice. In this application, a terminal side device may autonomously select and access the target network slice, so that network complexity may be reduced, and a latency in accessing a network may also be effectively reduced.
