The use of mobile phones to deliver context specific information in the form of advertisements tailored to a user’s profile, location among other related characteristics has been on the increase in the last few years. Location, in particular, is a key attraction to businesses in the delivery of advertisements. However, the widespread adoption of these applications continues to be hindered by among other factors the use of location determination and information delivery technologies such as GPS, Bluetooth, JAVA apps and WAP that are not universally available and accessible. Our proposed model for the development of a location based mobile advertising system is based on universally accessible and available technologies, namely SMS and USSD. The system uses symbolic locations and USSD drill down menus for user registration and information access. SMS is used for the delivery of the desired information to the user. This comprehensive solution architecture will be instrumental in the development of a new class of LBMA applications solely based on SMS and USSD.
