In this paper, the algorithm was designed of quad-tree spatial search based on spatial information multi-dimensional features, the traditional quad-tree algorithm has been improved to a specific spatial attribute value binding in the quad-tree leaf nodes, a large number with a specific operation irrelevant attributes are excluded, to the effect of finding(More)
In view of the multidimensional and enormous for spatial data, this paper provided a new based on the mobile oriented spatial information location algorithm. The algorithm used quadtree theory has nothing to do with a specific space to operate object excluded, so that the spatial location of the operation be able to fast access to the operation object,(More)
Mobile communication and Internet are the backbone of present information industry. With the implementation of 3G, both integrated has become the direction in the future. This paper aims at the technology between Mobile Communication Network and Internet interface technology, focuses on the analyze and design of the interface based on WAP, as well as gives(More)
It offers a solution based on WebGIS and MMS to search mobile spatial geographic information in the paper in which there is mobile spatial search platform with various images and words via establishing multithread wireless communication net model which is mainly based on MMS and partly SMS and making WebGIS as the spatial information engine of the system.(More)
The short message service(SMS) of mobile and Internet provided two convenient approaches for information transmission. This paper proposes a people's opinion collection and processing system(POCP) architecture integrated with SMS and Internet to support the information collection from different channel and centralized processing. The architecture includes(More)
The state of terminal device is critical to IC card system which consists of different kinds of terminal device. The paper introduce the structure of terminal device table and present a state location of IC Card terminal device based on two stage index strategy. As a keyword, the device number is a compressed four bit BCD code. The device number is divided(More)
