Service-Aware Traffic Session Timers for Wireless Networks

Solution Overview

Problem

Existing data traffic session timers in IP multimedia systems are service-agnostic, failing to accommodate the varying time constraints of different data traffic session types, such as emergency calls and messaging sessions.

Innovation Solution

Implementing service-aware traffic session timers that determine the specific timer values based on the type of data traffic session and its stage, allowing for tailored timer settings for different session types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a common set of timer values is used for all data traffic session types, then device complexity is reduced, but timer precision and adaptability deteriorate

Engineering Contradiction:

Improvetimer configuration complexityVSAvoidtimer adaptability to different session types

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by assigning different timer values to different data traffic session types (e.g., emergency calls, voice calls, messaging sessions). Instead of using a uniform timer configuration for all sessions, the system configures timer parameters locally according to the specific session type and its time constraints, thereby improving adaptability while maintaining manageable complexity through structured classification.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements parameter changes by dynamically selecting timer values based on the data traffic session type. The system changes timer parameters (such as timeout values, retry intervals) according to the specific requirements of different session types, allowing emergency calls to have shorter timers compared to messaging sessions, thus optimizing performance for each session category.

Inventive Principle:

Principle #35Parameter changes

2Loss of time

If shorter timer values are used for emergency calls, then response time is improved, but network resource holding time is reduced

Engineering Contradiction:

Improvesession setup timeVSAvoidnetwork resource holding time

Core Design Contradiction:

Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The patent applies local quality by assigning different timer values to different data traffic session types (e.g., emergency calls, voice calls, messaging sessions). Instead of using a uniform timer configuration for all sessions, the system configures timer parameters locally according to the specific session type and its time constraints, thereby improving adaptability while maintaining manageable complexity through structured classification.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making timer values adjustable based on session type rather than fixed. The system dynamically selects appropriate timer parameters for different session categories, allowing emergency calls to use shorter timers for faster response while other session types can use longer timers, thus optimizing the balance between response time and resource holding time for each specific scenario.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If longer timer values are used for messaging sessions, then user waiting tolerance is improved, but network resource utilization efficiency deteriorates

AI summary

Providing a data traffic session over a wireless network using service-aware traffic session timers includes: receiving, from a user equipment (UE), at a wireless network node, a session message for the data traffic session; based on at least content within the session message, determining a data traffic session type; based on at least the data traffic session type and a stage of the data traffic session, selecting a timer value from a set of timer values, the set of timer values each specific to a type of data traffic session; and based on a timer at the wireless network node reaching the selected timer value, performing a predetermined timer expiration action for the data traffic session. In some examples, the data traffic session type may be a non-emergency voice call, an emergency call, a video call, a wireless customer service call, or a messaging session.
