D2D Connection Setup Request Control via Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective method to control User Equipment (UE) in initiating Device-to-Device (D2D) connection setup requests, leading to excessive requests and potential power consumption issues.
Innovation Solution
Configuring pre-obtained configuration information by the network side for the UE to determine whether to transmit D2D connection setup requests, including support status, time intervals, and maximal request counts, thereby controlling when and how often D2D connection setup requests are initiated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UE autonomously initiates D2D connection setup requests without network control, then D2D connection establishment speed is improved, but the number of excessive requests increases and power consumption rises
Solution Approach 1:
The network side configures specific parameters including time interval thresholds and maximal request count thresholds. The UE compares its actual time interval and request count against these configured thresholds to determine whether to send connection setup requests, thereby controlling request frequency and reducing excessive transmissions that waste power.
Solution Approach 2:
The network side provides configuration information to the UE that includes control parameters for request transmission. The UE uses this feedback information to adjust its request behavior, comparing its current state against the configured thresholds and modifying its transmission decisions accordingly, which prevents excessive requests and optimizes power consumption.
2Productivity
If UE transmits D2D connection setup requests frequently without control, then connection establishment opportunities increase, but network resource waste increases
Solution Approach 1:
The network configures the UE with a maximal request count threshold within a specific time interval. The UE monitors how many requests it has sent and compares this count against the configured threshold, only transmitting new requests if the count has not exceeded the maximum, thereby preventing resource waste from excessive requests while maintaining adequate connection establishment opportunities.
Solution Approach 2:
The solution implements periodic control by defining a time interval parameter that structures when requests can be sent. The UE operates within this periodic framework, checking both the time interval condition and the request count condition, which creates a regulated pattern of request transmission that balances connectivity opportunities with resource conservation.
3Adaptability or versatility
If no configuration information is provided to UE, then UE autonomy is maximized, but request transmission control is lost
Solution Approach 1:
The UE autonomously determines whether to send connection setup requests by independently comparing its own operational parameters (actual time interval, actual request count) against the configured thresholds. This self-service mechanism maintains UE autonomy while achieving control, as the UE makes its own decisions based on the configured parameters rather than requiring continuous network intervention.
Solution Approach 2:
The network side performs preliminary action by configuring the UE with control parameters (time interval threshold, maximal request count threshold) before the UE begins autonomous operation. This preliminary configuration enables the UE to autonomously control its request transmission behavior without requiring real-time network commands, balancing autonomy with control.
