Solution Overview

Problem

Current wireless communication systems require fixed or low-mobility devices to frequently transmit uplink registration or location reports, which can lead to increased processing demands on the radio access network and reduced network capacity, especially when a large number of such devices are deployed in a given area.

Innovation Solution

Implementing a reduced reporting function that allows fixed or low-mobility devices to transmit route update messages at a lower rate, using either a timer or counter parameter to determine the transmission frequency, thereby reducing the burden on the network and improving capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed or low-mobility devices transmit route update messages at the standard rate, then the radio access network receives timely location information, but the network processing burden increases and capacity is reduced

Engineering Contradiction:
Improvelocation information timelinessVSAvoidnetwork capacity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by differentiating reporting requirements based on device mobility characteristics. Fixed or low-mobility devices are granted reduced reporting rates while mobile devices maintain standard reporting frequencies. This is implemented through network determination of device mobility status and configuration of device-specific reporting parameters, allowing the system to optimize for each device's actual movement patterns rather than applying a uniform reporting rate to all devices.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the reporting rate parameter dynamically based on device mobility classification. The network determines whether a device is fixed or mobile and configures appropriate reporting intervals accordingly. This parameter adjustment reduces the frequency of route update messages from fixed devices while maintaining timely location tracking for mobile devices, thereby resolving the contradiction between information timeliness and network capacity.

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If a large number of fixed wireless modules are deployed in a given area, then service coverage is improved, but the number of uplink registration messages increases exponentially

Engineering Contradiction:
Improveservice coverage areaVSAvoidnumber of registration messages
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent applies local quality by identifying and classifying devices based on their mobility characteristics within the network. Fixed wireless modules are detected and configured with reduced reporting requirements, while mobile devices maintain standard reporting. This differentiation allows the system to support large numbers of fixed devices without proportionally increasing the total message load, as fixed devices transmit significantly fewer registration updates compared to mobile devices.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If all devices transmit measurement reports periodically, then the network maintains accurate channel specifications, but fixed devices consume unnecessary network resources

Engineering Contradiction:
Improvechannel specification accuracyVSAvoidnetwork resource consumption
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent applies local quality by tailoring measurement reporting requirements to device mobility characteristics. Fixed devices, which experience stable radio conditions, are configured with reduced or aperiodic reporting, while mobile devices maintain frequent reporting to track changing channel conditions. This approach preserves channel specification accuracy for devices that need it while eliminating wasteful reporting from devices where conditions remain constant.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies partial action by requiring measurement reports only from devices that actually need them - mobile devices experiencing changing radio conditions. Fixed devices, where channel conditions remain stable, are exempt from periodic reporting requirements. This partial application of the reporting function maintains necessary measurement precision where needed while avoiding excessive resource consumption from unnecessary reports.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A system, method, and device for minimizing uplink registration or location reports, such as route update messages, for fixed or low-mobility devices. An access terminal (105) is configured to transmit route update messages to a radio access network (130) at a first rate and also at a reduced rate that is lower than the first rate. The access terminal is configured to transmit (205, 305) to the radio access network ( 130) a request to allow the access terminal (105) to use a reduced reporting function that causes the access terminal ( 105) to transmit route update messages at a reduced rate that is lower than the first rate, receive (210, 310, 415) a response that grants permission to use the reduced reporting function, and transmit (235, 265, 330, 350, 355) route update messages at the reduced rate in accordance with the reduced reporting function.
