Solution Overview

Problem

Existing wireless communication systems use a fixed inactivity timeout period for data radio bearers, leading to unnecessary power consumption and increased network signaling load, as they do not account for the specific characteristics of different data services.

Innovation Solution

Implementing a dynamic configuration of inactivity timeouts based on information provided by the wireless communication device, such as data service type, data amount, user history, and device state, to customize the timeout period for each data radio bearer, allowing for more efficient power management and reduced network overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a fixed inactivity timeout period is used for all data services, then the system is simple to implement and manage, but it causes unnecessary power consumption and increased network signaling load when the timeout is longer than needed

Engineering Contradiction:

Improvetimeout configuration complexityVSAvoiddevice power consumption

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic timeout configuration where the inactivity timeout period is adjusted based on data service characteristics. Instead of using a fixed timeout value, the system dynamically determines appropriate timeout periods according to the specific data service type, amount of data, user history, and device state, thereby optimizing power consumption while maintaining service quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the timeout parameter from a fixed value to a variable that adapts based on multiple factors including data service type, data amount, user history information, and device state. This parameter change enables the system to optimize power consumption by setting appropriate timeout values for different scenarios rather than using a one-size-fits-all approach.

Principle #35Parameter changes

2Device complexity

If a fixed inactivity timeout period is used for all data services, then the configuration is easy to manage, but it results in increased network signaling load when connections are maintained longer than necessary

Engineering Contradiction:

Improvetimeout management complexityVSAvoidnetwork signaling load

Core Design Contradiction:

Device complexityVSQuantity of substance

Solution Approach 1:

The system dynamically adjusts timeout configurations based on data service characteristics, allowing the network to release connections at optimal times. This dynamic approach reduces unnecessary signaling load by preventing prolonged maintenance of connections that are no longer needed, while keeping the management complexity reasonable through automated decision-making algorithms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms that consider data service type, data amount, user history, and device state to determine appropriate timeout values. This feedback-driven approach enables the system to automatically optimize connection management, reducing network signaling load by releasing connections when appropriate without requiring complex manual configuration.

Inventive Principle:

Principle #23Feedback

3Duration of action of moving object

If a longer inactivity timeout period is used, then intermittent data transmissions can resume more quickly without re-establishing connections, but the device consumes more power during idle periods

Engineering Contradiction:

Improveconnection availability durationVSAvoiddevice power consumption

Core Design Contradiction:

Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The patent implements parameter changes by adjusting the timeout value based on the specific data service and device state. For services requiring quick resumption, longer timeouts are applied, while for services where quick release is acceptable, shorter timeouts are used. This selective parameter adjustment optimizes the balance between connection availability and power consumption.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system applies different timeout qualities to different data services and device states. Instead of using a uniform timeout value, the patent tailors the timeout characteristic to local requirements - extending timeouts where quick resumption is critical and shortening them where power conservation is prioritized, thereby optimizing overall system performance.

AI summary

Method and apparatus for dynamic configuration of an inactivity timeout period for a data radio bearer used to transport data for a data service between a wireless communication device and a wireless network is provided. The method includes formatting a message including information related to the data service. The method further includes sending the message from the wireless communication device to the wireless network that is attendant to establishment of the data radio bearer for the data service. The method additionally includes receiving, at the wireless communication device, an assignment of the data service to the data radio bearer. The data radio bearer can have a customized inactivity timeout period defined by the wireless network based at least in part on the information in the message provided by the wireless communication device. The method also includes sending data for the data service over the data radio bearer.
