Problems solved by technology

Therefore, the operating load of the location service information providing device 105 is increased; and because the location service information providing device 105 needs to continuously interact with the requested party for location positioning information, the network load is increased, and the performance of the entire system is deteriorated
Deterioration in system performance is especially pronounced when requests for location-based subscription services surge

Embodiment Construction

[0028] will now combine image 3 A block diagram illustrating an information service system providing location-based subscription services according to the present invention.

[0029] Such as image 3 As shown, the information service system according to the present invention includes a location service information providing device 305, which responds to the location-based subscription service request sent by the requester j to the pervasive computing device 310 (also referred to as the requestee), and generates the Tasks related to subscription service requests. After the task is executed, subscription information corresponding to the subscription service request can be generated. These subscription service requests include location-related spatial and / or temporal trigger conditions (hereinafter referred to as trigger conditions, where a spatial and / or temporal condition related to a location is referred to as a trigger condition), and the identification of the pervasive comp...

Abstract

The present invention relates to information providing system for subscription service based on geographic position, information providing equipment, all-purpose operation equipment and information providing method. To respond one request partyí»s the subscription service request of one all-purpose operation equipment, the information providing equipment creates the task related the operate subscription service request, and the all-purpose operation equipment accepts task from the position service information providing equipment to locate and execute the task to create subscription information and to send the created subscription information to the request party. The present invention makes full use of the resource of the all-purpose operation equipment and balances the work amount of position information providing equipment, network and all-purpose operation equipment in the position 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...
