Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular communication systems do not support proximity awareness between User Equipments (UEs), limiting the integration of Device to Device (D2D) technology with application services and hindering the development of new service patterns.
Innovation Solution
A method and system where a network side device configures UEs for proximity awareness by determining and transmitting lists of service identifiers and temporary device identifiers, allowing UEs to obtain service information directly through D2D communication, enabling them to filter and inquire about service information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If UEs communicate through relay and proxy functions provided by eNB and gateway, then communication can be established in existing cellular network, but service information cannot be obtained for proximity awareness between UEs
Solution Approach 1:
The patent extracts the service information acquisition function from the traditional relay-based communication architecture. By introducing D2D communication, UEs can directly obtain service information for proximity awareness without relying on eNB and gateway relay functions, thus resolving the contradiction between maintaining communication capability and enabling proximity awareness information access.
Solution Approach 2:
The patent introduces a service information acquisition mechanism as an intermediary layer between UEs. This intermediary enables UEs to obtain service information directly through D2D communication while maintaining compatibility with the existing cellular network architecture, thus resolving the information loss issue without completely replacing the complex relay infrastructure.
2Adaptability or versatility
If D2D technology is introduced to enable direct communication between UEs, then new service patterns and proximity awareness can be achieved, but integration with application services is not yet standardized
Solution Approach 1:
The patent implements a universal service information acquisition mechanism that works across multiple service types and D2D communication scenarios. The defined procedures and message formats enable the system to support various application services (proximity awareness, direct communication, etc.) through a unified framework, thus resolving the contradiction between achieving diverse service patterns and maintaining ease of system integration.
Solution Approach 2:
The patent employs parameter-based configuration mechanisms to adapt the D2D communication system to different service requirements. By defining configurable parameters for service information acquisition, message formats, and communication protocols, the system can be easily integrated with various application services without requiring fundamental architectural changes, thus resolving the integration difficulty.
3Ease of operation
If UEs obtain service information directly through D2D communication, then proximity awareness between UEs is enabled, but existing cellular network architecture must be extended
Solution Approach 1:
The patent implements preliminary configuration of service information acquisition parameters and D2D communication settings by the network before UEs engage in direct communication. The network pre-configures UEs with necessary parameters, message formats, and protocols, enabling ease of operation during actual D2D communication while managing network architecture complexity through centralized pre-configuration rather than ad-hoc negotiations.

AI summary
Disclosed are a UE configuration method, network side device and system for proximity awareness in the present invention, which are used to achieve the function of obtaining the service information by proximity awareness between terminals in a cellular communication system. The network side device configures the service ID of each service type to be sent by the transmission UE and the temporary device ID, and the network side device configures the service ID filtering template for the receiving UE according to the service types to be received by the receiving UE, and thus the configured transmission UE and the receiving UE can obtain the service information by proximity awareness.
