Description

Location tracking service system and method using internet message service terminal equipped with GPS receiver {Tracking service system using internet message service device loading GPS receiver and method}

The present invention relates to a location tracking service system using an Internet message service terminal equipped with a GPS (Global Position System) receiver. More particularly, the present invention relates to a high frequency transmission module and a radio call of an internet message service terminal. The present invention relates to a location tracking service system and method for a wireless paging terminal which transmits to a wireless paging exchange station through a network and provides the transmitted location information through a web service system based on a geographic information system (GIS) connected to the Internet. .

Currently, a location tracking service system using a mobile communication network and a mobile communication terminal is made based on the function of a mobile communication terminal which performs location registration through an assigned wireless communication channel. That is, the mobile communication terminal connected to the mobile communication network transmits the location registration data to the base station based on the designated cell. For example, registration when the power is turned on and off, time-based registration, distance-based registration (the mobile station Registrations that deviate from a certain distance from the last registration point), location area change registrations, parameter change registrations, command registrations by radio calling exchanges, implicit registrations and traffic channel registrations.

The paging exchange station receives the location data of the mobile communication terminal connected to the mobile communication network from the base station and registers the location data in the Location Registration Control Subsystem (LRS), and the location tracking system registers the location data registered in the paging exchange station. A service related to location information (for example, a service provided by a map application service provider (MASP)) is performed using the location information.

As mentioned above, the location tracking service system acquires location data of a tracking target and introduces a geographic information system to provide detailed location information to a user. A geographic information system stores natural and socio-economic information in accordance with geographical and spatial location. It is a technology that analyzes and utilizes for various purposes and provides economic efficiency and efficiency for data collection and data processing.

Geographic information system is a geographic model of the real world. The target data are accessed, changed, and managed in relation to each other, so you can experiment with analysis of environmental changes, analysis of trends, or decision making and prediction of results. The data collection is performed using a high density digital tape (HDDT) that records data through a sensor from a conventional map, various literature data, satellite imaging, and aerial photographing plane.

Therefore, the location tracking service system adopting the geographic information system can provide more geographic related information in addition to providing the user with simple location information. An easy example is a traffic geographic information system.

However, the location tracking system using the location registration data has a lot of errors (maximum error range 2Km) in the location detection, thus revealing the limitations on the service provided. In this regard, a technology for mounting a GPS receiver in a mobile communication terminal to enable more accurate location tracking (minimum error 30m) is expected to be widely used.

GPS is a satellite positioning system that consists of 24 satellites launched by the United States and control stations, mobile stations, and fixed stations of ground stations. GPS can be used to find location data on the earth's plane at any location.

Mobile communication terminals equipped with GPS receivers usually use Code Division Multiple Access (CDMA) and frequency channels (800 MHz band (cellular), 1.8) with a spread bandwidth of 1.23 MHz per 1FA (Frequency Alignment). GHz band (PCS) is used to transmit the location information, and in addition to the communication service, the user who uses only the location tracking service has to pay a lot of channel fees.

Currently used radio transmission channels include radio calling channels (160MHz and 320Hz), trunked radio systems (TRS) (370MHz and 390MHz), book communication, broadcasting relay, TRS RX, and mobile communication. RX (cellular) and airport communication channels (formed from 752MHz to 894MH), wireless data RX channel (896 ~ 900MHz), CT channel (910 ~ 915MHz, 959 ~ 960MHz), wireless data TX channel (938 ~ 940MHz), PCS transmit and receive channels (1.73-1.78 GHz, 1.82-1.87 GHz) and IMT-2000 transmit / receive channels (1.885-2.25 GHz, 2.110-2.200 GHz).

However, the CT channel and the radio call channel in these wireless transmission paths are relatively inadequate compared to the PCS transmission / reception channels and the mobile communication RX channels, and thus the transmission paths are empty. For example, this is the case where the memory of data chips inserted in various devices is upgraded wirelessly, and used for wireless remote meter reading, vehicle remote diagnosis and logistics management system.

Recently, a representative example of providing a data communication service using a wireless transmission path with sufficient free space is an Internet Message Service (IMS), which is a channel and text for a conventional pager (pager). By using a dedicated transmission / reception terminal (hereinafter, referred to as an “Internet message service terminal”), various text services may be provided in connection with an Internet web service server. In other words, users can send and receive various one-way message-type data such as Internet, email, text, file, voice message, etc., and SKYTEL Co., Ltd. of the United States, such as "NPCS (Narrow band PCS)", "AMS (Advanced Messaging) Service in the name of "Service".

The above-described Internet message service terminal is a kind of pager having the existing pager function (text transmission / reception function) as a basic function, and an additional service function applied based on the basic pager function.

The prominent advantage of such an Internet message service is the low usage fee. In other words, the user can use a wide range of Internet message services unlimitedly by paying a certain amount each month regardless of the usage of the communication channel.

Considering the trend of the utilization of the wireless communication channel in the real world, it is time to find ways to use the radio calling frequency bands and the transmission-only frequency bands that are less used for the location-related services based on the geographic information system.

Accordingly, the present invention has been made to solve the above-mentioned general problems, and an object of the present invention is to provide location data using an Internet message service terminal equipped with a GPS receiver and a wireless transmission channel that lags behind. The present invention provides a location tracking service system and a method for transmitting the same to a wireless calling exchange station and providing precise location information through a GIS-based internet web service system.
