  1. 1. LOCATION TRACKING AND ALLERTING APPARARTUS AND METHOD Potharaju S R Aditya S.Sahithya M.S -Software Engineering M.S -Software Engineering Vellore Institute of Technology Vellore Institute of Technology Ph: +91-9789685001 Ph: +91-9786720112 aditya992005@gmail.com muthyamsahi185@yahoo.com Abstract a mobile terminal during periods ofThis invention describes a product that is emergency and for alerting friends, familyused during emergency incidents where the and other contacts of that user of thelocation of people can be used to track who status of that user.

Thus, if a user findsinvention arose in an attempt to provide an himself in the vicinity of an emergencyimproved method for locating and tracking situation or may be a short distance outsideusers of mobile terminals and for alerting it, he is often not able to inform his friendstheir contacts with their status details. and family immediately that he is safe. Even if he is, he needs to call each separate contact individually and this also adds to the1.

  2. 2. The present invention arose in an attempt to status using a messaging service. Thisprovide an improved method for locating information can then be used multiple timesand tracking users of mobile terminals and by all people who are associated with that person. This highly streamlinedfor alerting their contacts with their status communication leads to fast and efficientdetails feedback of everyones status to all interested parties. With previously proposed systems, each individual colleague, family2. Related Work member or other members must contact the user individually to determine his status. Essentially, the invention relates to a A person can use a number of methods tomethod of effectively locating a mobile sign up for the service and interact (forterminal (and therefore the user of the example: web, mobile, messaging, IVR, callmobile terminal) during an emergency or centre). They can then use any of theseother incident and of being able to establish methods to manage a group or groups ofwhether the user, based upon his position people that they are interested in knowingrelative to the incident, is likely to be safe or the status of during an emergency incident.not. If he is at sufficient distance from theincident or the incidents epicentre then a During an incident, the incident details aremessage is sent to a number of first been entered into the system. Thepredetermined contacts or other users in a system will use any one of a number ofgroup in effect stating that that user is OK. technologies to both locate appropriateThat is, he is at a sufficiently safe distance users and find their distance from theaway from the incident and so he is incident . These methods could be forunaffected by it. If the user is determined to example: personal GPRS based devices,be less than a predetermined distance from PDAs or smart cell phones equipped withthe incident epicentre, then the user may or GPS (global positioning service) receiversmay not be safe.

  3. 3. Based on the location and the response, the product determines the status from the messages received and it is summarised and detailed information on each persons group is returned to each group member and or The product is designed only to give group owner. Further status information can information it has received and not to be requested via the messaging channel. generate false positives or negatives. The product has built in automatic testing procedures that are continually using all sub` components and report their status. The product uses standard techniques and safe mapping references to locate and track incidents and the distance of a person from an incident may calculated using the simple equation D= ( A2 B2) see FIG. 2, or otherwise. The product allows fast and Xi,yi accurate dissemination of information regarding the incident to key people and the general population 3.Location tracking System Architecture An embodiment using mobile phones, cell phone location via registered cell, and SMS messaging to contact people is shown in FIG Figure 1 3. A number of mobile terminals (shown in A the figure as cell phones 2) are connected to a telecommunications network via one or more cell towers. In the example shown, the Xi,yi first cell phone 1a is connected through a R B first base station (cell tower) 3a to a service provider 4. Two further cells phones 1b and D DdD A 1c are connected through a second base station 3b to the service provider 4. Cell phone 1c in this instance also is equipped with a GPS system 10 enabling its position to be tracked by using the GPS satellite system 11 for more accurate positioning. The mobile telephone communications network 4 is connected to an incident centre 5 over SMS (text) gateway 2 and an LBS Figure 2 (location base service) gateway 5. The
