Solution Overview

Problem

Existing wireless communication systems face inefficiencies in aligning traffic information between control and user planes, leading to unnecessary resource consumption and overhead in reconfiguring discontinuous reception (DRX) cycles.

Innovation Solution

The proposed solution involves indicating a first packet associated with a packet periodicity, allowing for the alignment of traffic information between control and user planes, and using this information to reconfigure DRX cycles through control elements, thereby conserving computing and power resources at user equipment (UE).

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traffic information is aligned between control and user planes through packet periodicity indication, then resource consumption and overhead are reduced, but system complexity increases due to additional coordination mechanisms

Engineering Contradiction:
Improvepower consumptionVSAvoidsystem complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The traffic pattern information (packet periodicity) is indicated in advance to the control plane before DRX reconfiguration is needed. This allows the control plane to pre-calculate and prepare the optimal DRX parameters, avoiding the need for complex real-time analysis and reducing the coordination overhead during actual reconfiguration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The packet periodicity indicator acts as an intermediary parameter that bridges the user plane traffic characteristics and the control plane DRX configuration. By introducing this intermediate representation, the system avoids direct complex interactions between traffic flow management and DRX control, simplifying the overall coordination mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If DRX cycles are reconfigured based on aligned traffic information, then processing efficiency at UE is improved, but signaling overhead increases due to additional control elements

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsignaling overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The packet periodicity information is merged with existing control plane signaling messages rather than being transmitted as separate dedicated signaling. This consolidation approach delivers the necessary traffic pattern information without increasing the overall signaling overhead, as the data is piggybacked on existing communication channels.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of energy

If packet periodicity is indicated to align traffic information, then resource consumption is reduced, but measurement and detection difficulty increases

Engineering Contradiction:
Improveresource consumptionVSAvoidpacket periodicity detection
Core Design Contradiction:
Loss of energyVSDifficulty of detecting and measuring

Solution Approach 1:

The user plane function automatically detects and reports its own traffic pattern characteristics (packet periodicity) to the control plane. This self-service approach eliminates the need for complex external measurement and detection mechanisms, as the system generates and communicates its own traffic statistics through existing reporting channels.

Inventive Principle:
Principle #25Self-service

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a traffic source or an application function (AF) may determine traffic information including a packet periodicity associated with one or more traffic flows. The traffic source or the AF may transmit, to a network function, the traffic information including an identifier related to a first packet associated with the packet periodicity. Numerous other aspects are described.
