Solution Overview

Problem

Existing 5G communication networks face challenges in efficiently managing resource allocation for increasing multicast groups, particularly in scenarios where multicast services exhibit unstable packet sizes and intervals, leading to inefficient use of resources and increased power consumption.

Innovation Solution

A method for determining stable multicast service states based on packet size and interval characteristics, activating a multicast scheduling mode, and optimizing PDCCH resource allocation through a multicast group resource allocation list and bitmap management to improve resource utilization and reduce power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional resource allocation methods are used for multicast groups in 5G networks, then resource allocation can be performed, but resource utilization becomes inefficient and power consumption increases when packet sizes and intervals are unstable

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

Solution Approach 1:

The patent implements dynamic resource allocation by transitioning between two scheduling modes: PTM mode for stable multicast services and unicast scheduling mode for unstable services. The system dynamically adjusts the scheduling approach based on real-time packet size and interval stability, thereby optimizing resource utilization and reducing power consumption adaptively

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the scheduling parameter state by detecting stability metrics (packet size variation and interval consistency) and switching between PTM and unicast modes accordingly. This parameter-based state change enables the system to optimize resource allocation efficiency and power consumption based on actual service conditions

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If PTM transmission mode is used for multicast services, then resource allocation can be simplified, but resource allocation becomes inaccurate when packet characteristics are unstable

Engineering Contradiction:
Improveresource allocation simplicityVSAvoidresource allocation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system dynamically selects between PTM mode (simpler allocation) and unicast mode (more precise allocation) based on service stability. When packets are stable, PTM provides simple efficient allocation; when unstable, the system switches to unicast for precise resource allocation, thus resolving the contradiction between simplicity and accuracy

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms by monitoring packet size and interval characteristics to determine service stability. This feedback loop enables the system to adjust the scheduling mode appropriately, ensuring resource allocation accuracy is maintained while preserving the simplicity of PTM when conditions permit

Inventive Principle:
Principle #23Feedback

AI summary

A method, a device and a non-transitory computer-readable storage medium for scheduling resources for multicast services, the method comprising: performing packet detection for data of a multicast service received from a network-side device. If the data has a relatively stable packet size at the time of detection and is characterized by periodicity, the multicast scheduling mode is initiated for the user equipment where the multicast group corresponding to the multicast service is located.
