Proximity Discovery Control via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack an efficient method for a communication source UE to discover and notify the presence of a communication target UE in proximity, leading to unnecessary power consumption and the inability of mobile communication providers to offer proximity communication services due to the lack of control over direct communication path establishment between UEs.
Innovation Solution
A mobile communication system that includes a server device, a control device, and a communication terminal capable of obtaining information about proximity terminals and requesting approval for direct communication path establishment, managing identification and permission information, and allocating radio resources based on permission, thereby optimizing the discovery and communication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication source UE starts discovery at random to find communication target UE, then the UE can potentially discover proximity terminals, but the UE wastes power consumption when the communication target UE is not in proximity or cannot perform direct communication
Solution Approach 1:
The patent introduces a server as an intermediary that manages proximity terminal information and direct communication path establishment. The server receives discovery requests from communication source UEs, manages the discovery process, and provides results to reduce unnecessary random discovery attempts by UEs, thereby lowering power consumption while maintaining discovery reliability
Solution Approach 2:
The patent implements preliminary action by having the server pre-manage proximity terminal information and communication capabilities before actual communication needs arise. The server maintains updated information about which UEs are in proximity and capable of direct communication, so when a communication source UE needs to discover targets, the server can provide pre-filtered information rather than requiring exhaustive random discovery
2Ease of operation
If the UE establishes direct communication path without provider control, then the UE can perform direct data transmission, but the mobile communication provider cannot offer proximity communication services due to lack of control
Solution Approach 1:
The server acts as an intermediary between UEs and the mobile communication provider, enabling the provider to control and manage direct communication paths. The server receives requests from UEs, coordinates with the provider's policy framework, and manages the establishment process, thus maintaining ease of operation for UEs while providing the provider with necessary control capabilities for service management
Solution Approach 2:
The patent implements feedback mechanisms where the server continuously monitors and reports on direct communication path establishment status to the provider. This feedback loop enables the provider to adapt services based on actual communication patterns and maintain control over proximity communication services while allowing flexible UE operation
3Productivity
If the UE performs unnecessary discovery when communication target UE is not in proximity, then the UE attempts to establish communication, but the discovery process is wasted and power consumption increases
Solution Approach 1:
The server performs preliminary actions by pre-establishing and maintaining information about proximity relationships and communication capabilities before UEs need to discover each other. This preliminary preparation allows the server to quickly determine whether discovery is necessary and provide accurate information, eliminating wasted discovery attempts and reducing power consumption
Solution Approach 2:
The server as an intermediary coordinates the discovery process by determining whether communication target UEs are actually in proximity and capable of direct communication before UEs expend energy on discovery. The server filters out unnecessary discovery cases, improving discovery efficiency and reducing wasted energy consumption
Data Source
AI summary
In a proximity service, when positional information is notifies to a server in advance and the proximity service is started, UE that transmits and receives data receives the proximity degree including a communication target UE from the server before proximity discovery is performed to discover the communication target UE, and the UE controls unnecessary proximity discovery by discovering the communication target UE based on the proximity degree.
