Location-aware Content Delivery Service Using Publish/Subscribe

The delivery of location-aware content tailored to user location and personal requirements is going to be the premier service in next generation mobile networks. This service should provide mobile users with up-to-date information according to their preferences and current geographical location. In this paper we propose an architecture for the location-aware content delivery service. The architecture comprises a publish/subscribe component which supports push-based delivery of data to interested users, a presence service for defining and updating user presence information, and a profile handler for storing and updating user profiles. The presence service interacts with the location management component that can locate the applied user terminal. First, we explain the concept of publish/subscribe and discuss its applicability to location-aware content delivery. Next, we describe the presence and profile management service with the applied solution for location management. Additionally, we define the structure of presence information and personal user profiles. Finally, we present a scenario showing the interaction between our components and conclude with the discussion of service implementation.
