Solution Overview

Problem

Mobile devices in NBIoT applications experience communication delays due to significant changes in the communication environment, leading to increased waiting times for establishing a communication connection, especially when moving or experiencing poor signal strength.

Innovation Solution

A method to dynamically adjust the detection period for neighbor network devices by determining if a low communication delay event is triggered, allowing for a shorter detection period when necessary, thereby reducing the time interval for synchronization operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the detection period for neighbor network devices is extended to reduce power consumption, then energy efficiency improves, but communication delay increases

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication delay

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the detection period adjustable rather than fixed. The system dynamically switches between a first detection period (for normal operation) and a second detection period (when communication delay is detected), allowing optimal adaptation between power saving and communication responsiveness based on real-time conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the detection period parameter based on detected communication conditions. When communication delay is detected, the system switches to a shorter second detection period to reduce delay; otherwise, it uses a longer first detection period to save power, thus optimizing the parameter based on operational needs.

Inventive Principle:

Principle #35Parameter changes

2Loss of time

If the detection period is shortened to reduce communication delay, then communication responsiveness improves, but power consumption increases

Engineering Contradiction:

Improvecommunication delayVSAvoidpower consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the detection period based on detected communication conditions. The processor monitors for communication delay events and switches between detection periods accordingly, ensuring short periods are used only when necessary to maintain responsiveness while minimizing overall power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The detection period parameter is changed based on operational conditions. The system uses a longer first detection period under normal conditions to conserve power, and switches to a shorter second detection period only when communication delay is detected, optimizing the balance between power consumption and responsiveness.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the mobile device performs frequent detection operations to maintain connection quality, then connection reliability improves, but battery life deteriorates

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent implements dynamic adjustment of the detection period based on detected communication conditions. The system maintains connection reliability by switching to a shorter second detection period when communication delay is detected, while extending the first detection period during normal operation to preserve battery life, thus adaptively balancing reliability and power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The detection period parameter is dynamically changed based on communication condition monitoring. The system switches between a longer first detection period (for battery conservation) and a shorter second detection period (for maintaining connection reliability during delays), optimizing the parameter to balance reliability requirements with battery life preservation.

Inventive Principle:

Principle #35Parameter changes

AI summary

A communication device includes a wireless transceiver circuit and a processor. The wireless transceiver circuit transmits and receives wireless signals. The processor processes the wireless signals to obtain information regarding a first period configured by a serving network device in order to measure signal strength of the serving network device and obtain information regarding a second period configured by the serving network device in order to detect a neighbor network device. The processor further determines whether an event related to low communication delay is triggered. When determining that the event related to low communication delay is not triggered, the processor performs a detection operation to detect the neighbor network device according to the second period. When determining that the event related to the low communication delay is triggered, the processor performs the detection operation to detect the neighbor network device according to a third period shorter than the second period.
