Method and System for Performance Evaluation of Positioning of Mobile Communication Terminal Using Wireless Communication Network and A-GPS Method Method and System for Accessing Mobile Communication Terminal Position Determination Performance of Mobile Terminal by Using Wireless Communication Network and A-GPS

The present invention relates to a method and system for evaluating performance related to positioning of a mobile communication terminal using a wireless communication network and an Assisted-GPS (A-GPS) scheme. More specifically, when determining the location of a mobile communication terminal using a wireless communication network and the A-GPS method, the location of a location based service (LBS) wireless communication network is determined using various parameters of the IS (Interim Standard) -801-1 standard. The present invention relates to a method and system for comprehensively evaluating performance.

In order to provide communication services such as the Internet beyond the recent space, many companies are spurring the development of a new technology called wireless Internet. Wireless Internet refers to an environment and technology that enables users to use Internet services through a wireless network while the user is on the move. The development of mobile phone-related technologies and the rapid increase in mobile phone penetration have further accelerated the development of this wireless Internet environment.

On the other hand, location-based services, among a variety of wireless Internet services using a wireless communication terminal such as a mobile phone or PDA (PDA), in particular, has been in the spotlight due to its wide range of usability and convenience. Location-based wireless Internet services include Geographic Information System (GIS), which provides rescue requests, response to crime reports, and geographic information for neighboring areas, differentiation of mobile communication charges based on location, traffic information, vehicle navigation and logistics. It can be used in various fields and situations such as control and location-based customer relationship management (CRM).

In order to use the location-based wireless Internet service, it is essential to know the location of the wireless communication terminal. Currently, as a method of identifying a location using wireless communication, a method using GPS is typical.

GPS is a system that can be located anywhere in the world by 24 GPS satellites orbiting the earth at an altitude of about 20,000 kilometers. GPS uses radio waves in the 1.5 GHz band, and on the ground there is a coordination center called Control Station, which collects and synchronizes information transmitted from GPS satellites. do. In general, triangulation is used as a method of positioning using a GPS system. Three satellites are required for triangulation, which requires a total of four GPS satellites, including one observational satellite for time error.

In more detail, since GPS already knows the position of each of the three satellites, the GPS is positioned by measuring the distance between the satellite and the GPS receiver. Since the distance from the satellite to the GPS receiver is transmitted from the satellite, the propagation time can be known from the difference between the time when the radio wave is transmitted from the satellite and the time received by the GPS receiver with the built-in clock.The propagation time is multiplied by the speed of light. To calculate the distance.

On the other hand, GPS is freely available to anyone, there is no limit to the number of users, it is possible to perform continuous positioning in real time, and relatively accurate positioning is possible.

However, the lack of multi-path and visibility limits the ability to locate in the city center, makes it almost impossible to accurately position in places where satellites are not visible (such as out of radio waves), such as in tunnels or underground buildings. There is a problem that a large error occurs in the positioning state according to the arrangement of the satellite viewed from the receiver. In addition, the time to first fix (TTFF), which is the actual time required for the GPS receiver to determine its location in the first place, sometimes takes about several minutes to ten minutes or more. There is a problem that causes great inconvenience.

In order to compensate for the disadvantages of the GPS method, an A-GPS method for determining a location of a mobile communication terminal by combining a resource of a wireless communication network with a GPS method has been developed and used. In the A-GPS method, the mobile communication terminal collects information necessary for positioning at the same time from the GPS satellites and the wireless communication network, so that the mobile communication terminal can determine the location in three dimensions. Send or receive data or messages using the parameters defined in the standard.

On the other hand, in the positioning system of a mobile communication terminal, performance evaluation regarding positioning is a very important task for a network operator. However, the performance evaluation of positioning in the A-GPS method remains at the level at which the measurer simply reads the call flow message defined in the IS-801-1 specification displayed on the monitor screen of the notebook computer. This method of checking call flow messages transmitted and received when positioning only by text can only assume the simple fact that the positioning is not well performed, and there is a disadvantage in that it is impossible to confirm why the positioning is not performed well. . In other words, it is impossible to determine whether the location determination is not caused by a defect in a device installed in a wireless communication network, a defect in a mobile communication terminal itself, or a feature (high building, mountain, tree, etc.). There is a problem that it is very difficult to respond quickly.

In order to solve the above problems, the present invention provides the performance of the LBS wireless communication network using various parameters of the IS-801-1 standard when determining the location of the mobile communication terminal using the wireless communication network and the A-GPS method. The purpose of this study is to present a method and system for comprehensive evaluation.

The distance error for each positioning sequence is displayed as a point in real time, and each distance error point is connected by a line so that the change of the distance error can be easily identified.

In addition, the LBS wireless network analysis program has a total positioning frequency (FWD MSG), a radius error within 10 m, 20 m, 30 m, 50 m, 70 m, 100 m, 150 m as shown in FIG. If the distance error of the number of positioning and total positioning points is considered small, the distance error statistical information corresponding to the distance error range of 67% and 95% is analyzed and displayed. Referring to FIG. 4, it can be seen that 67% of the positioning point within 38.5 m radius and 95% of the positioning point within 100.7 m radius are displayed based on the actual position of the mobile communication terminal 110.
