Abstract

The present invention relates to an information providing system, an information providing device, a pervasive computing device and an information providing method for providing subscription services based on geographic locations. In response to a subscription service request for a pervasive computing device issued by a requesting party, the location information providing device generates a task related to the subscription service request, and the pervasive computing device receives the task from the location service information providing device to perform location self-location , and location-based calculations to execute the task to generate subscription information, and send the generated subscription information to the requester. The invention fully utilizes the resources of the pervasive computing device, and further balances the workload of the location service information providing equipment, the network and the pervasive computing device in the location service system.

Description

technical field

[0001] The present invention relates to an information providing system, an information providing device, a pervasive computing device and an information providing method, in particular to an information providing system, an information providing device, a pervasive computing device and an information providing method for providing subscription services based on geographic locations. technical background

[0002] With the development of network and communication technology, people rely more and more on modern communication tools to obtain timely information. Among them, providing location-based subscription services for mobile users with the help of the Global Positioning System has become an interesting research topic in the industry.

[0003] Fig. 1 is a block diagram of an existing system for providing location-based information services.

[0004] Usually, a location service information providing device 105 receives a subscription about the requested part...
