Wireless UE Group Multicast for Mode Change Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in transitioning multiple user equipment (UEs) between different operational modes, such as idle, inactive, and connected, due to the need for individual signaling by base stations, which can overload network resources and increase power consumption.
Innovation Solution
A method and apparatus for a base station to multicast a message to a group of UEs, indicating a mode change, thereby reducing the need for individual signaling and optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual signaling is used to transition UEs between operational modes, then each UE can be accurately controlled, but network resources become overloaded and power consumption increases
Solution Approach 1:
The patent combines multiple individual mode change commands into a single group command message that can be transmitted to multiple UEs simultaneously. The base station identifies a group of UEs that need to transition between operational modes and sends one unified signaling message containing group identification and mode transition instructions, thereby reducing the number of separate transmissions and conserving network power while maintaining accurate control over each targeted UE's mode transition.
2Reliability
If individual signaling is used for each UE mode change, then precise control is achieved, but network overload occurs
Solution Approach 1:
The patent merges multiple individual mode change operations into a single group signaling operation. The base station prepares one group command message that encapsulates mode transition instructions for multiple UEs, reducing the total number of signaling operations the network must process. This approach maintains precise control over which UEs transition modes while significantly reducing network processing load compared to sending individual commands to each UE.
3Loss of energy
If group multicast signaling is used for mode changes, then network resources are conserved, but individual UE control flexibility is reduced
Solution Approach 1:
The patent segments the network's UE population into distinct groups based on their mode transition requirements. Each group command message targets a specific segment of UEs identified by group identification, allowing the base station to apply different segmentation strategies for different scenarios. This segmentation approach enables efficient group-level control for UEs with similar needs while preserving the ability to create fine-grained segments when individualized control is required, thus balancing resource conservation with control flexibility.
4Reliability
If multiple individual messages are sent for mode changes, then each UE receives specific instructions, but signaling overhead increases
Solution Approach 1:
The patent combines multiple individual mode change messages into a single group command message that is transmitted over the air to multiple UEs simultaneously. Instead of sending separate downlink messages to each UE, the base station creates one unified message containing group identification and mode transition commands that all target UEs can receive and process. This merging dramatically reduces the volume of signaling messages in the network while ensuring each UE receives its specific mode transition instructions through the group broadcast mechanism.
