In a perspective of a service provider within a MaaS vehicle, a service provider mobile device may determine a distance and approaching direction of the service requestor mobile device. The service provider mobile device may determine the distance and the approaching direction through GPS coordinates using a unified gateway or through a more direct communication. The MaaS vehicle via the service provider mobile device may provide information regarding the distance and the approaching direction of the service requestor mobile device. This information may be in the form of audio and/or visual cues.
