Intelligent Paging System for Mobile Devices

Solution Overview

Problem

Mobile devices in idle state are frequently activated by base stations for incoming messages, regardless of their importance, leading to reduced battery life and increased wireless network traffic due to unnecessary communication.

Innovation Solution

A system that determines the characteristics of incoming messages and applies rules to decide whether to activate a mobile device, reducing unnecessary transitions to an active state and optimizing message delivery based on user preferences and message priority.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If base stations send requests to mobile devices for every incoming message, then messages are delivered to users, but battery life is reduced and wireless network traffic increases

Engineering Contradiction:

Improvemessage deliveryVSAvoidbattery life

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes the parameter of message priority classification, dividing messages into different priority levels (high, medium, low). This allows the paging system to adjust its behavior based on message characteristics, sending paging requests only for high-priority messages while allowing low-priority messages to wait until the device becomes active, thus reducing unnecessary battery consumption and network traffic

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary classification and filtering of messages before triggering device activation. By evaluating message characteristics and priority levels in advance, the system determines which messages warrant immediate device activation and which can be delivered when the device naturally becomes active, preventing premature or unnecessary wake-ups

Inventive Principle:

Principle #10Preliminary action

2Reliability

If base stations send requests to mobile devices for every incoming message, then messages are delivered to users, but wireless network traffic increases

Engineering Contradiction:

Improvemessage deliveryVSAvoidwireless network traffic

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system changes the parameter of message priority classification, dividing messages into different priority levels (high, medium, low). This allows the paging system to adjust its behavior based on message characteristics, sending paging requests only for high-priority messages while allowing low-priority messages to wait until the device becomes active, thus reducing unnecessary battery consumption and network traffic

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system extracts and filters out low-priority messages from the immediate paging process. By separating messages based on priority, the system removes unnecessary paging requests for non-urgent messages, thereby reducing wireless network traffic while maintaining reliable delivery of important communications

Inventive Principle:

Principle #2Taking out (Extraction)

3Use of energy by moving object

If mobile devices remain in idle state, then battery life is extended, but message delivery time increases

Engineering Contradiction:

Improvebattery lifeVSAvoidmessage delivery time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system changes the parameter of message priority classification, dividing messages into different priority levels (high, medium, low). This allows the paging system to adjust its behavior based on message characteristics, sending paging requests only for high-priority messages while allowing low-priority messages to wait until the device becomes active, thus reducing unnecessary battery consumption and network traffic

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts the device activation strategy based on message priority. For high-priority messages, the system immediately pages the device to minimize delivery time. For low-priority messages, the system allows the device to remain idle, accepting longer delivery time in exchange for extended battery life. This dynamic adaptation resolves the contradiction between battery conservation and timely delivery

AI summary

An access gateway comprises a processor. The processor is operable to determine a message type of a received packet. The processor is further operable to apply a paging rule. The paging rule is related at least in part to the message type of the received packet. The processor is further operable to determine whether to send a request to transition the mobile device to an active state based on the paging rule. The processor is further operable to send a request, when appropriate, to transition the mobile device to an active state.
