Network Slice Identity Processing for Service-Matched Cell Access

Solution Overview

Problem

Existing communication systems fail to ensure that terminals access network slices that can provide the required services, leading to performance issues when the network slice service supported by the accessed cell does not match the terminal's requirements.

Innovation Solution

The terminal and network devices process network slice and terminal identity information to facilitate access procedures, enabling terminals to connect to cells that can provide the necessary network slice services, thereby improving performance by ensuring timely access to suitable cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal accesses the cell based on signal strength measurement, then the connection quality is improved, but the terminal may access a cell that cannot provide the required network slice service

Engineering Contradiction:

Improveconnection qualityVSAvoidnetwork slice service matching

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The terminal performs preliminary processing of network slice identity information before the access procedure. The terminal obtains network slice identity information from downlink data or network configuration, processes this information to determine required network slice services, and uses this information to guide cell selection before actually accessing the cell, ensuring service matching is considered in advance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network device provides feedback to the terminal about which cells support the required network slice services. The network device receives the terminal's identity information, determines whether accessed cells can provide required services, and sends back indication information to guide the terminal to select appropriate cells that match both signal quality and service requirements

Inventive Principle:

Principle #23Feedback

2Productivity

If the terminal always accesses the cell with the best signal quality, then the communication performance is improved, but some communication services cannot be carried out when the cell does not support the required network slice

Engineering Contradiction:

Improvecommunication performanceVSAvoidservice availability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The terminal changes the selection parameters for cell access by incorporating network slice identity information alongside signal strength measurements. Instead of relying solely on signal quality parameters, the terminal processes network slice information to create a composite selection criterion that includes both communication performance metrics and service compatibility metrics

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The terminal performs preliminary processing of network slice identity information before the access procedure. The terminal obtains network slice identity information from downlink data or network configuration, processes this information to determine required network slice services, and uses this information to guide cell selection before actually accessing the cell, ensuring service matching is considered in advance
