Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing mobile communications systems, the network side cannot interact with the application layer of user equipment (UE), leading to suboptimal resource allocation and utilization, which degrades user experience due to the inability to perform scheduling optimization and service adjustments.
Innovation Solution
An information exchange method where the application layer of the UE sends information to the RRC layer, which is then forwarded to the network side using an RRC message, enabling the network to perform service adjustments and optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network side uses traditional bearer-based data exchange, then service transmission is ensured through network control, but the network side cannot interact with the application layer of UE, leading to suboptimal resource allocation and utilization
Solution Approach 1:
The patent introduces an RRC message as an intermediary carrier to transport application layer information from the UE application layer to the network side. The RRC layer acts as a mediator that enables communication between the application layer and the network side, allowing the network to obtain application-specific information without direct application layer access, thus resolving the information loss while maintaining network-controlled service transmission.
Solution Approach 2:
The patent creates a new communication dimension by enabling application layer information to be transmitted through the RRC signaling channel, which traditionally only carried control information. This dimensional extension allows application layer data to coexist with control plane communications, enabling the network to access application layer information without disrupting the existing bearer-based service transmission framework.
2Adaptability or versatility
If the network side cannot access application layer information, then network architecture remains simple and stable, but scheduling optimization and service adjustments cannot be performed
Solution Approach 1:
The patent makes the RRC message multi-functional by enabling it to carry both traditional control information and application layer information. This universal carrier approach allows the existing RRC signaling mechanism to serve dual purposes: maintaining network control functions while simultaneously transporting application-specific data, thereby enhancing service adaptability without significantly increasing system complexity.
Solution Approach 2:
The application layer information is self-transmitted by the UE through the RRC layer to the network side, without requiring additional network infrastructure or complex mediation. The UE autonomously packages and sends its application layer information using existing RRC messaging capabilities, enabling the system to gain adaptability while minimizing added complexity.
3Loss of time
If application layer information is transmitted through RRC layer to the network side, then scheduling optimization and resource allocation can be performed, but additional information exchange mechanisms are required
Solution Approach 1:
The patent merges application layer information transmission with existing RRC signaling operations. Instead of creating separate channels or protocols for application data, the solution combines application information with control plane RRC messages, allowing simultaneous transmission of control and application data through the same mechanism, thereby reducing waiting delays without proportionally increasing system complexity.
Solution Approach 2:
The UE prepares and transmits application layer information through the RRC layer in advance, before network scheduling decisions are made. This preliminary information exchange allows the network to have application context ready when making scheduling decisions, reducing waiting delays by eliminating the need for subsequent information requests and responses.
