Abstract

Disclosed is a new mobile application that allows a user to see a list of people from a stored contact list that are near the user. The mobile application utilizes the cellular signal architecture to identify all individuals stored in a user’s mobile address book or contacts that are connected to the same cellular tower as the user.

Smart Mobile Address Book Application for Nearby Contacts

In many situations, such as attending a conference or a public event, a person is interested in finding out who else is in attendance that might be a friend or colleague.

A system is needed that allows a mobile device user to access a list of contacts that are physically nearby.

There are no known solutions to this exact problem. In the mobile industry, one application is used to find friends. Though this application is an approach to identify locations of friends, it does not solve the same problem. It can refer a user to the location of someone using the same application; however, it does not provide a list of the user's contacts that are in the same area. Utilizing Bluetooth* for connectivity offers a limited range, and therefore does not provide a good solution.

The novel contribution is a mobile application that utilizes the cellular signal architecture to identify all individuals stored in a user's mobile address book or contacts that are connected to the same cellular tower as the user. The application displays a subset of the smart phone address book contacts that are within the vicinity of the user's current location (within certain distance). The idea is to use the cell tower to identify all mobile phones connected through the same tower to calculate the longitude and latitude of the mobile phone. The application then scans the mobile phone address book to retrieve the tower identification (ID) to which this contact list is connected. It calculates the longitude and latitude of other contacts in the user's address book sharing the same tower. Hence, the application can identify the exact location of the mobile phone. The application then presents a list of all address book contacts near the location determined through a predefined radius.

When comparing the proposed solution with current solutions or alternatives, it is clear that it is a complete solution. The application to find friends utilizes vendor cloud capabilities to identify friends' locations. It does not provide a clear list of address book contacts that are close by. It requires that the two parties use the same application for this function to work. It also puts many restrictions on finding locations of friends to the point that most of the time the result is returned as 'Cannot determine location'. The Bluetooth connectivity is very limited in range and requires that people identified can be located within a very limited distance (within the same room). Even in this case, it is sometimes hard to identify whether the device bel...
