Solution Overview

Problem

Current mechanisms for transitioning a wireless transmitter/receiver unit (WTRU) between CONNECTED and INACTIVE/IDLE states are sub-optimal, leading to inefficient resource utilization, unnecessary signaling, and excessive power consumption due to reliance on current data activity without considering future data traffic predictions.

Innovation Solution

The WTRU receives predictive data configuration messages indicating triggering conditions and data traffic parameters, determines a data traffic prediction level, and initiates a transition to connected state based on these conditions, facilitating more efficient state transitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the WTRU transitions to INACTIVE/IDLE state based on current data activity monitoring, then power consumption is reduced and resource utilization is improved, but unnecessary signaling occurs and sub-optimal resource utilization happens when data arrives soon after transition

Engineering Contradiction:
Improvepower consumptionVSAvoidsignaling delay
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The network performs preliminary action by predicting future data traffic arrival at the WTRU before the transition decision is finalized. This prediction allows the network to anticipate whether transitioning to INACTIVE/IDLE state will result in unnecessary signaling, thereby avoiding sub-optimal transitions while still achieving power savings when appropriate.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the WTRU remains in CONNECTED state to avoid frequent transitions, then signaling overhead is reduced, but resource utilization becomes sub-optimal and power consumption increases

Engineering Contradiction:
Improveresource utilizationVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The network uses feedback from data traffic patterns and prediction algorithms to dynamically determine the optimal state for the WTRU. By continuously monitoring traffic characteristics and applying prediction mechanisms, the network receives feedback that enables it to make informed decisions about when to transition the WTRU to INACTIVE/IDLE state versus maintaining CONNECTED state, thereby optimizing both resource utilization and power consumption.

Inventive Principle:
Principle #23Feedback

3Device complexity

If current data activity-based transition mechanisms are used, then implementation complexity is low, but sub-optimal WTRU power usage and unnecessary signaling occur

Engineering Contradiction:
Improvetransition mechanism complexityVSAvoidpower consumption
Core Design Contradiction:

Solution Approach 1:

The network performs preliminary prediction of data traffic arrival before making transition decisions. This advance prediction mechanism adds intelligence to the transition process without significantly increasing implementation complexity, as it builds upon existing data activity monitoring while incorporating predictive algorithms to avoid sub-optimal transitions and reduce unnecessary signaling.

Inventive Principle:
Principle #10Preliminary action

AI summary

In an embodiment, a method implemented in a wireless transmit receive unit, WTRU, comprises: receiving in one or more first messages from a network, information on predictive data configuration indicating one or more triggering conditions for performing connection to the network and indicating one or more data traffic prediction parameters; determining a data traffic prediction level while in idle/inactive state based on the one or more data traffic prediction parameters: in response to the determination of the data traffic prediction level fulfilling at least one of the one or more triggering conditions, transmitting, to the network, a second message comprising a request for connection and at least one cause value for the connection: receiving, from the network, a third message comprising a response to the request for connection; and initiating a transition to connected state.
