Solution Overview

Problem

The increasing complexity of terminal device capability information leads to significant signaling overhead and increased load on core network devices during registration and connection establishment in wireless communication systems.

Innovation Solution

Terminal devices report capability information using assigned capability identifiers, which are stored by network devices, reducing the need to transmit and store extensive capability information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If terminal device reports detailed capability information, then network device can provide accurate configuration, but signaling overhead increases significantly

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent uses capability identifiers as simplified copies or references to the actual detailed capability information. Instead of transmitting the full capability information, the terminal device reports compact identifier values that point to pre-defined capability sets stored in the network device, thereby reducing signaling overhead while maintaining configuration accuracy

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The network device pre-stores multiple capability information sets with their corresponding identifiers before the terminal device needs to report capabilities. This preliminary preparation allows the network device to quickly match and retrieve the appropriate capability information based on the reported identifier, eliminating the need to transmit detailed capability data during connection establishment

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If core network device stores detailed capability information of all terminal devices, then accurate service provisioning is enabled, but network device load increases

Engineering Contradiction:
Improveservice provisioning capabilityVSAvoidnetwork device load
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces storage of large detailed capability information with storage of compact capability identifiers. The network device maintains a mapping table that associates identifier values with full capability descriptions, allowing efficient storage and retrieval while reducing memory requirements and processing load

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The capability information system is segmented into two parts: (1) a compact identifier layer that the terminal device reports, and (2) a detailed capability information layer that the network device stores and processes. This segmentation allows the terminal device to send minimal information while the network device handles the complex capability management

Inventive Principle:
Principle #1Segmentation
