The present invention relates to a location notification and confirmation service system and a service providing method using a map on a background screen of a mobile communication terminal. More specifically, friends who want to share location information can join the friend finder service, download the map application of the desired area from the friend finder server, set it as the wallpaper of the mobile terminal, and display the location using the map application. When transmitting, the friend search server stores the location information in the group registered as a friend of the database or updates the stored location information, and transmits the location information stored in the database to the mobile communication terminal registered as a friend. The present invention relates to a location notification and confirmation service system and a service providing method using a map on a background screen of a mobile communication terminal, which can notify a friend of his / her location on a terminal background screen and confirm the location of the friends.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless communication networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call wirelessly to mobile terminal users. It has a feature that can be provided regardless of time and place, and provides a voice message service by providing a text message service. It is complementing the service.

Meanwhile, with the establishment of the Internet based on Transmission Control Protocol / Internet Protocol (TCP / IP), various types of data can be searched using the Internet or various data including text, voice, image, video, etc. In addition to the rapid development of a system capable of real time transmission, in order to use a variety of communication services using the Internet in a better environment, the diffusion of high-speed communication network, etc. is greatly increased.

In addition, in recent years, in order to provide a communication service that transcends space, a wireless Internet service for providing an Internet communication service to a mobile communication service subscriber through a wireless communication network has emerged, and many companies have been developing technology for the wireless Internet. The wireless Internet service is an advanced personalization service according to the use of the terminal of the individual and has a feature of providing a unique information based on the mobility of the user. Mobile communication service subscribers can receive various types of information such as news, weather, sports, securities, exchange rates, and traffic information in various forms such as text, voice, still image, and video through wireless Internet service.

Among various wireless Internet services using a mobile communication terminal, in particular, a location based service (LBS) has gained much attention due to its wide utility and convenience. Location-based service refers to a communication service that locates a mobile communication terminal such as a mobile phone, a personal digital assistant (PDA), a notebook PC, and provides additional information related to the identified location. Location-based services include requests for rescue, response to crime reports, Geographical Information System (GIS) for providing information on neighboring areas, differentiation of mobile communication charges based on location, traffic information, vehicle navigation and logistics control, location-based CRM It can be used in various fields and situations such as customer relationship management.

In order to use the location-based service, it is essential to know the location of the wireless communication terminal. Location Determination Technology (LDT) is a technology for identifying the location of a wireless communication terminal. It is a network-based method using a base station received signal and a handset based using a Global Positioning System (GPS) signal. -Based) method, and recently, a hybrid method that combines the two technologies to improve the position accuracy has been developed.

Figure 1 shows a system configuration of a conventional friend search service using this LDT technology.

 Conventional friend-finding service system is a mobile communication terminal 100, the mobile communication terminal (100, 130) and the mobile communication network (110) relaying the transmission and reception of voice and data between the mobile communication terminal (100, 130) and the friend search service system, the above-described mobile Checking the location information of the mobile communication terminal 130 to confirm the location of the communication terminal 100, the location information of the mobile communication terminal 100 is disclosed when there is a service request from the mobile communication terminal 130 to confirm the location It consists of a friend-finding service system 120 for transmitting to the desired mobile communication terminal 130.

When the mobile communication terminal 100 permits the disclosure of a location by joining a friend search service, the friend search service system 120 receives the location information of the mobile communication terminal 100 from the mobile communication network 110 and stores the location information in the database. The location information is measured by the above-described LDT. When the user of the mobile communication terminal 130 that wants to check the location of the mobile communication terminal 100 requests a service by accessing the friend search service system 120 through wired or wireless Internet, the friend search service system 120 is stored in a database. The mobile station 100 transmits the location information of the mobile communication terminal 100 to the mobile communication terminal 130 to check the location through the mobile communication network.

This conventional friend search service has the advantage that it is possible to check the location of friends or acquaintances without the transmission and reception of voice or text messages, there are the following problems.

First, in order to check the location of a friend or acquaintance, it is cumbersome because it requires access to the wireless Internet, and there is a problem in that a connection fee is charged when the wireless Internet is connected.

Second, this service uses a location measurement technology (LDT) such as GPS to obtain location information of a mobile communication terminal. Although location location techniques (LDTs) have been developed to obtain more accurate location information, there is a problem that there is a limit in exchanging location information between people who share a specific narrow area.

In order to solve this problem, the present invention, all the friends who want to share the location information to join the friend finder service to download the map application of the desired area from the friend finder server to set as the wallpaper of the mobile terminal, the map application When the location is displayed by using the sender, the friend finder server stores the location information in the group registered as a friend of the database or updates the location information stored therein, and the mobile terminal registered as a friend is stored in the database. The purpose of the present invention is to provide a location notification and confirmation service system and method using a map on the background of a mobile terminal, by transmitting the location information to inform the friends of their location on the background of the mobile terminal and to confirm the location of the friends. have.
