Solution Overview

Problem

Existing communication apparatuses are limited to connecting with their own company's servers and struggle to form alliances with partner companies, making it difficult to communicate with evolving partner company systems.

Innovation Solution

A communication apparatus that acquires second firmware and connection information from a first server to connect to a second server, enabling communication with various partner company systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a user equipment camps on a frequency for long-term monitoring, then the user can receive dedicated paging messages, but the battery consumption increases due to continuous monitoring

Engineering Contradiction:
Improvepaging message reception reliabilityVSAvoidbattery consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network side configures different monitoring periodicities for different frequencies. The user equipment monitors the first frequency (with better signal quality) at a longer period, and the second frequency (with weaker signal quality) at a shorter period. This periodic action with varying intervals reduces overall monitoring frequency while maintaining reliable paging reception.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Different monitoring strategies are applied to different frequencies based on their local signal quality characteristics. The first frequency with stronger signal quality allows for less frequent monitoring, while the second frequency requires more frequent monitoring. This local differentiation optimizes energy consumption while maintaining reliability.

Inventive Principle:
Principle #3Local quality

2Reliability

If the user equipment monitors multiple frequencies for paging messages, then the paging message reception reliability is improved, but the monitoring complexity and processing overhead increase

Engineering Contradiction:
Improvepaging message reception reliabilityVSAvoidfrequency monitoring complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring task is segmented into different frequencies with different monitoring periodicities. The network side provides separate configuration information for each frequency, allowing the user equipment to independently manage monitoring schedules for each frequency, thereby reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The monitoring periodicity is made dynamic and configurable rather than fixed. The network side can adjust the monitoring periodicity for each frequency based on signal quality conditions, allowing the system to adapt to changing environments without increasing structural complexity.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the network configures frequent monitoring on all frequencies, then the paging message delivery reliability is improved, but the network signaling overhead and resource allocation complexity increase

Engineering Contradiction:
Improvepaging message delivery reliabilityVSAvoidnetwork configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The network applies different monitoring periodicity configurations to different frequencies based on their local signal quality. This localized configuration approach ensures reliable paging delivery on each frequency while avoiding uniform over-monitoring, thereby reducing overall network signaling overhead and configuration complexity.

Inventive Principle:
Principle #3Local quality

AI summary

In a communication apparatus communicating with a server based on connection information and firmware for connecting to the server, in order to appropriately communicate with various servers, the communication apparatus is configured to communicate with a first server based on first connection information and first firmware for connecting to the first server, and acquire, from the first server, second firmware for connecting to a second server different from the first server.
