Solution Overview
Problem
The challenge of obtaining accurate location information for requestors and providers in on-demand service systems is exacerbated by environmental interference and communication delays, leading to inefficient resource allocation, misidentification, and increased system resource usage due to canceled and duplicated requests.
Innovation Solution
Implementing local device communications between provider and requestor computing devices to triangulate accurate locations using signal strength measurements, minimizing reliance on network-reported locations and reducing unnecessary system communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network-reported locations are used for service matching, then system-wide resource allocation can be managed, but location accuracy deteriorates due to environmental interference and communication delays
Solution Approach 1:
The patent introduces local device-to-device communications as an intermediary mechanism between provider and requestor devices. This intermediary layer enables direct location verification and sharing without relying solely on network-reported locations, thereby resolving the contradiction between system-wide resource allocation reliability and individual location accuracy by allowing both network-level matching and device-level precision to coexist
Solution Approach 2:
The patent implements preliminary location verification through local communications before final service matching occurs. By pre-establishing accurate location information through device-to-device signaling, the system avoids subsequent mismatches and cancellations, thus improving both location accuracy and overall service reliability simultaneously
2Productivity
If traditional communication through on-demand matching system is used, then centralized resource allocation is achieved, but communication time delay increases
Solution Approach 1:
The patent segments the communication process into two distinct layers: centralized matching system communications for resource allocation decisions, and local device-to-device communications for immediate location verification and coordination. This segmentation allows time-sensitive operations to occur locally without waiting for network round-trips, reducing communication delay while preserving centralized resource allocation efficiency
Solution Approach 2:
The patent adds a new communication dimension by implementing direct device-to-device signaling alongside the existing network-mediated communication channel. This dimensional expansion creates parallel communication paths where urgent location-related information can be exchanged instantly between devices, bypassing network latency while the centralized system continues to manage overall resource allocation
3Productivity
If accurate location information is not available, then service providers can be dispatched to request locations, but misidentification of requestors occurs leading to canceled and duplicated requests
Solution Approach 1:
The patent implements feedback mechanisms where provider devices receive location information from requestor devices through local communications, verify the accuracy of this information, and use it to confirm requestor identity before arrival. This feedback loop prevents misidentification by allowing providers to cross-check location data directly with requestors, eliminating canceled and duplicated requests while maintaining fast service delivery
Solution Approach 2:
The patent performs preliminary requestor identification and location verification through local device communications before the provider travels to the request location. By pre-confirming identity and location accuracy, the system avoids wasted trips and duplicated requests, thus improving both service delivery efficiency and identification reliability

AI summary
Embodiments provide techniques, including systems and methods, for improving the accuracy of location information for requestor and provider devices in an dynamic transportation matching system using local communications between computing devices. For example, embodiments allow a provider computing device to identify, pair, and/or communicate with a requestor computing device upon arrival near a request location for a ride matching request. The provider computing device may use signal strength measurements associated with signals received from the requestor computing device to identify a proximity to the requestor computing device and/or to triangulate an accurate location of the requestor computing device. Additionally, the provider computing device may use a combination of the location reported by the ride matching system and the signal strength of the paired connection to identify the location of the requestor computing device.
