Description

Large-scale real-time location information processing method using main memory database system and spatial indexing technique {THE METHOD OF MASSIVE REAL-TIME LOCATION INFORMATION PROCESS USING MAIN MEMORY DBMS AND SPATIAL INDEX}

The present invention relates to a retrieval and efficient processing method for a client's location information request when location determination using a mobile communication switching terminal is required. More particularly, the present invention provides a method for efficiently real-time location information of a client identified through a mobile communication switching terminal. It relates to a system for storing, managing, and handling retrieval requests.

Currently, the real-time location information processing method is slowing down the performance of real-time location information processing by using a disk-based general relational database system for processing tens to millions of transactions.

In addition, although the real-time location information belongs to spatial data, the spatial indexing technique does not apply the spatial information and thus provides little mutual information about the location of clients.

The present invention can improve the transaction processing time by several times by using the main memory database system instead of the disk-based database system to solve the conventional problems as described above, and search for real-time location information by using the spatial indexing technique. We propose a system that provides various additional functions for.

The first object of the present invention is to reduce the hardware cost by improving the performance speed by using the main memory database system in storing and managing the real time location information and processing more real time location information in one server.

A second object of the present invention is to provide a variety of functions for location search by applying a spatial index technique in storing and managing real-time location information.

There may be a plurality of embodiments of the present invention. Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

1 is a block diagram of a large capacity real-time location information processing system according to the present invention.

As described above, the large-scale real-time location information processing system according to the present invention provides a web site on the Internet 20 so that clients 10 (10/1 to 10 / n) can search location information including a mobile subscriber number. A mobile communication switching terminal that performs location identification and mobile communication exchange service by the base station 40 in the service area of the mobile communication network and the location of the mobile communication terminal carried by the web server 30 and the client 10 50, and the positional information retrieval and processing terminal 60.

The mobile communication switching terminal 50 includes a location server 51 that manages exchange and client location tasks, and a WAP (WAP) for converting HTML (HyperText Markup Language) format information into WML (Wireless Markup Language) format information. Wireless Application Protocol) gateway 52.

The location information retrieval and processing terminal 60 includes a location retrieval server 61 for processing location retrieval-related transactions, a location processing server 62 for storing and managing location information grasped from the location server, and clients 10. It consists of a location DB (63) where the location information of.

The location processing performed through the large capacity real time location processing system according to the present invention configured as described above will be described in more detail with reference to the flowchart of FIG. 2.

First, the client 10 desiring the location information of a certain client visits a web site provided by a web site operating means such as a web server 30 through the Internet 20 (S201).

When any client accesses a web site, the web server 30 may provide an initial menu screen, and the client 10 may select location information search or another menu from the initial menu.

In this step, if the client 10 selects the location information search, the screen is switched to the next screen. In the switched screen, the client 10 inputs the mobile communication subscriber number and the quality of the location information of the counterpart client 10 to determine the location. Select Of Service value. (S202 to S203)

When the client 10 enters the mobile communication subscriber number and selects the Quality Of Service value, the web server 30 transmits the data to the location search server 61. (S204 to S205)

The location search server 61, which has received the information necessary for the location search from the web server 30, transmits the information to the location processing server in order to obtain the real time location information of the client 10, which is the location object to be identified. (S206)

The location processing server 62, which has received the information necessary for the location search from the location search server 61, receives the real time location information of the corresponding client 10 from the location DB 63, which stores the real time location information of the client 10. Search (S207).

The location processing server 61 checks whether the real-time location information of the client 10 retrieved from the location DB 63 satisfies the QoS required. (S208)

If the real-time location information retrieved from the location DB 63 in step S207 satisfies the QoS required, the location processing server 62 transmits the real-time location information of the corresponding client to the client 10 that requested the location information (S209). )

If the real-time location information retrieved from the location DB (63) does not satisfy the required QoS in step S207, the location processing server 62 is a client that is required to search the location server 51 to obtain location information satisfying the QoS. The mobile communication subscriber number of 10 is transmitted to request real time location information (S210).

The location server 51 receiving the location request requests the location information by using the VLR of the base station 40 and the HLR of the mobile communication exchange terminal 50 to determine the location of the corresponding client 10. To the real-time location processing server 62. (S211)

The location processing server 62, which has acquired the new real time location information from the location server 51, transmits the location information of the corresponding client to the client 10 that has requested the real time location information (S209).

As described above, the present invention has an effect of maximizing execution speed by using a main memory database system in managing real-time location information in which an update occurs in real time. In addition, by applying spatial indexing techniques, spatial search related functions can be provided.
