Elevator Guidance via Proximity-Based Mobile Device Localization

The patent implements periodic transmission of contact signals by the first communication unit within a predetermined range. Instead of continuous transmission, the system uses periodic pulses to establish contact with the second communication unit, reducing signal interference while maintaining localization capability. This is evident in the method steps where contact signals are sent at specific intervals to determine user position without causing overlapping signals.

The patent divides the building into multiple zones with separate first communication units, each operating independently within its predetermined range. This segmentation prevents signal interference between different transmitter/receiver units by ensuring that each unit only communicates with devices in its specific zone, thereby maintaining localization accuracy without harmful interference.

The patent transmits different navigation information to different users based on their specific needs, positions, and authorization levels. Instead of providing all possible information to everyone, the system tailors the information content locally to each user's situation. This ensures information completeness for each user while maintaining security by not exposing all data to all users.

The patent changes the parameters of data transmission based on user authorization and context. The system adjusts what information is transmitted, when it is transmitted, and how it is transmitted based on the user's access rights and current position. This dynamic parameter adjustment ensures that users receive complete navigation information relevant to them while maintaining security constraints.

The patent uses the user's existing mobile communication device (smartphone) to perform multiple functions: receiving contact signals for localization, displaying navigation information, providing directional guidance, and storing relevant data. This eliminates the need for separate stationary terminals while maintaining ease of information access and adding user mobility. The mobile device becomes a universal tool for all navigation functions.

The patent enables users to self-serve by using their own mobile devices for navigation without requiring interaction with stationary terminals. The system pushes navigation information automatically to the user's device based on their position and needs, eliminating the need for users to actively seek out terminals or manually query for information. This enhances both ease of operation and user mobility simultaneously.
