D2D Taxi Service Direct Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call taxi services require users to go through a separate call center, leading to delays, increased power consumption due to GPS usage, and unnecessary maintenance costs for taxi companies, as well as indirect information sharing between users and drivers.
Innovation Solution
A Device to Device (D2D) communication-based method and apparatus that allows users to directly connect with nearby taxi terminals, enabling quick call taxi services without intermediaries, by receiving service information, transmitting requests, and establishing session connections with available taxis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a call center agent is used to connect users with taxis, then service reliability is improved, but waiting time increases and service efficiency decreases
Solution Approach 1:
The patent extracts and removes the call center intermediary from the taxi service system, enabling direct peer-to-peer communication between users and taxi drivers through a decentralized communication protocol. This eliminates the waiting time associated with call center agents while maintaining service reliability through direct connections.
Solution Approach 2:
The system enables users and taxi drivers to directly establish connections and exchange information without requiring call center agents. The automated matching and communication system allows participants to serve themselves, reducing waiting time while maintaining service quality.
2Measurement precision
If GPS mode is turned on to obtain position information, then position accuracy is improved, but power consumption increases
Solution Approach 1:
The patent combines multiple position determination methods including GPS, cellular tower triangulation, Wi-Fi positioning, and inertial sensing into a unified hybrid positioning system. This allows the system to achieve accurate position information while consuming less power by using lower-power methods when sufficient accuracy is available and only activating GPS when necessary.
Solution Approach 2:
The system dynamically adjusts positioning parameters such as GPS update frequency, accuracy requirements, and alternative method selection based on current power availability, service requirements, and environmental conditions. This allows optimization of the balance between position accuracy and power consumption in real-time.
3Reliability
If a separate server and call center are used for call taxi service, then service reliability is improved, but operational costs increase
Solution Approach 1:
The patent extracts the centralized server and call center components from the traditional taxi service architecture, replacing them with a decentralized peer-to-peer communication system. This reduces operational costs and system complexity while maintaining service reliability through direct connections between users and drivers.
Solution Approach 2:
The system enables automatic service matching, information exchange, and transaction coordination between users and taxi drivers without requiring centralized server management or call center operations. This self-organizing capability reduces operational costs and simplifies the overall system architecture.
4Speed
If direct D2D communication is used between user terminal and taxi terminal, then service speed is improved, but communication range is limited
Solution Approach 1:
The patent segments the communication system into direct D2D communication for nearby devices and network-based communication for extended range. The system automatically selects the appropriate communication mode based on distance, ensuring fast direct communication when available and extended range through network infrastructure when needed.
Solution Approach 2:
The system implements a nested communication architecture where direct D2D communication is embedded within a broader network-based communication framework. When devices are in range, fast direct communication is used; when out of range, the system nests within network infrastructure to maintain connectivity and service capability.

AI summary
An apparatus and a method for providing a call taxi service based on D2D communication are provided. When a user terminal executes a call taxi service, a call taxi service request is transferred to a terminal from at least one taxi located in a neighboring area of the user terminal, and then the user terminal directly selects one taxi or one taxi is selected through a competition between taxis. As a result, a process of providing the call to the selected taxi. Accordingly, the user has an advantage of using a quick call taxi service without going through a separate call center.
