System and method for tracking people
First Claim
1. A method of tracking people, comprising the steps of:
- transmitting a polling request to a mobile device associated with a particular person of interest;
in response to the polling request, transmitting a location signal including positional data and time data representative of the location of the mobile device at the time of reception of the polling request;
determining if the location signal transmitted by the mobile device is being received and if communication is interrupted, then storing the positional data and the time data in on-board memory until communication is re-established and at that time, re-transmitting the location signal and clearing the stored positional data and the time data from the on-board memory, wherein the stored positional data and time data is stored for a pre-set time threshold after which subsequent positional data and time data overwrites the original stored positional data and time data;
receiving a supplemental location signal from a fixed sensor, the supplemental signal including supplemental positional data and supplemental time data representative of the location of the mobile device when the mobile device is detected within proximity of a fixed sensor;
recording the positional and time data and the supplemental positional and supplemental time data in a database as a set of geographic positions and corresponding times associated with a path of the person of interest;
generating a visual display image of the path of the person of interest overlaid on a geographic map; and
transmitting the positional and time data and the supplemental positional and supplemental time data to a single guide of a group of people, the group of people including the person of interest.

Abstract
The system and method for tracking people provides for the tracking of individuals in large crowds, such as the tracking of individual pilgrims during the Hajj pilgrimage in Mecca. A polling request is initially transmitted from a tracking station to a mobile device associated with a particular person of interest. Upon receipt of the polling request, a location signal is transmitted back to the tracking station. The location signal includes positional and time data representative of the location of the mobile device at the time of transmission. Additionally, a supplemental location signal is also transmitted to the tracking station, the supplemental location signal being representative of the location of the mobile device when the mobile device is detected within proximity of a fixed sensor. A visual display image of the path of the person of interest is then displayed at the tracking station overlaid on a geographic map.

9. A method of tracking people, comprising the steps of:
-
transmitting a polling request to a mobile device associated with a particular person of interest; in response to the polling request, transmitting a location signal including positional data and time data representative of the location of the mobile device at the time of reception of the polling request; transmitting a supplemental location signal through a fixed sensor, the supplemental signal including supplemental positional data and supplemental time data representative of the location of the mobile device when the mobile device is detected within proximity of the fixed sensor; determining if the location signal transmitted by the mobile device is being received and if communication is interrupted, then storing the positional data and the time data in on-board memory until communication is re-established and at that time, re-transmitting the location signal and clearing the stored positional data and the time data from the on-board memory, wherein the stored positional data and time data is stored for a pre-set time threshold after which subsequent positional data and time data overwrites the original stored positional data and time data; recording the positional and time data and the supplemental positional and supplemental time data in a database as a set of geographic positions and corresponding times associated with a path of the person of interest; generating a visual display image of the path of the person of interest overlaid on a geographic map; and transmitting the positional and time data and the supplemental positional and supplemental time data to a single guide of a group of people, the group of people including the person of interest. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 20)

17. A system for tracking people, comprising:
-
means for transmitting a polling request to a mobile device associated with a particular person of interest; means for transmitting a location signal including positional data and time data representative of the location of the mobile device at the time of transmission of the location signal upon receipt of the polling request; a near field communication initiator for transmitting a supplemental location signal including supplemental positional data and supplemental time data representative of the location of the mobile device when the mobile device is detected within proximity of a fixed near field communication target; means for recording the positional and time data and the supplemental positional and supplemental time data in computer readable memory as a database including a set of geographic positions and corresponding times associated with a path of the person of interest; means for determining if the location signal transmitted by the mobile device is being received and if communication is interrupted, then storing the positional data and the time data in on-board memory until communication is re-established and at that time, re-transmitting the location signal and clearing the stored positional data and the time data from the on-board memory, wherein the stored positional data and time data is stored for a pre-set time threshold after which subsequent positional data and time data overwrites the original stored positional data and time data; means for generating a visual display image of the path of the person of interest overlaid on a geographic map; and transmitting the positional and time data and the supplemental positional and supplemental time data to a single guide of a group of people, the group of people including the person of interest. - View Dependent Claims (18, 19)
