Location of a mobile user is an utmost important because of its seamless mobility feature. The technology for finding such user in mobile network is now one of the most promising and research needed fields. Classification of potential location based system (LBS) application can be done as for public safety, consumer needs and enterprise business.  

This application is the part of location-based query system along with SMS center.

The main objective of this application is to share its mobile location using SMS reply automatically to them who seeks its location. SMS is the cheapest method to use as compare to internet in developing world like Nepal. It is also total offline method hence easy to operate for the most general people.  In the emergency case when there is to locate the person using mobile, currently there is no easy way out hence Postmag technology has developed this system collaborating with telecom company.

The core functionality of this application is divided into two parts. It means it does two kinds of work which is related to SMS handling. The basic work of this application is to send SMS for location query purpose to SMS center manually. Another is to give reply SMS automatically to SMS center upon getting such location query SMS.

Currently a local mobile number has been used as SMS center number but later in update version its number will be changed to 5-digit number.

Part 1 core function:  As a query number, user send SMS manually to make location query of any other mobile number.

With this application, user can send SMS to find the location of mobile number currently registered in country Nepal via SMS center. If the targeted number is not in Nepal then its location cannot be obtained.

After this application run, user is first notified its terms and condition and then proceed to Main View.

In Main view, user will load the target number by using its own contact view and send SMS using button provided in main view. Such sent SMS will be sent to SMS center in pre-defined format and pre-defined number. SMS center number is local mobile number of country Nepal. Both format and SMS center number has been hard coded in application code. As SMS center number is from country Nepal thus tariff charge depends on the query location’s telecom company.

Upon getting such query request, SMS center will check location sharing subscription of target number. On validating its subscription, SMS center will notify such request to target number having this application installed.

Part 2 core function: Reply to location query request by SMS center

Upon getting location request, this application in targeted number now send back SMS automatically as reply to SMS center with a content about its GSM network parameter in pre-defined format. SMS center upon getting such information, it will convert the GSM parameter into physical real-world address by running its own algorithm on GSM database using one of the popular Okumara hata model. SMS center then send physical real-world address to the query number as a location address of target number.

This application sends SMS to SMS center only. It will not send SMS to any other number either for location query or for reply to location request. Similarly, it reads the SMS content of those SMS only which is sent by SMS center. As reply of the location request, this application will send GSM parameter only in coded form hence its privacy also has been well maintained.

The process can be seen in Main view screen and also the content that sent can be seen in default SMS application provided by phone itself. Hence there is no hidden work it does.
