Description

Bus Information Guide System and Method

The present invention relates to a bus information guidance system. In particular, a GPS system is mounted on a bus to transmit bus current status information to a bus information management server through a satellite, thereby providing bus information to a mobile terminal. It is about a guidance system.

The mobile communication system is composed of a mobile terminal, a base station (BTS), a base station controller (BSC) and a mobile switching center (MSC). The mobile terminal is a digital cellular network (DCN) and a personal mobile communication service (PCS). Service) and next-generation mobile communication service (Mobile Terminal) for IMT-2000, and the base station changes the signal format between the mobile terminal and the base station controller to be suitable for the wireless link and the wired link. It is a means of access between each function and cell operator, base station operation management, service state management of hardware and software in base station, resource allocation and configuration for call traffic, base station operation information collection, base station operation, monitoring and fixing Perform monitoring functions such as sub-devices related to The mobile switching center then configures an access point for user traffic between the base station controller management and the mobile communication network and the mobile switching center of the general telephone network or the same mobile communication system.

With the development of mobile communication technology, the use cost of mobile terminal is lowered and the call quality is also improved to make high quality call even in a driving vehicle, and the use of mobile terminal is increasing rapidly. It is becoming a necessity of modern people by providing it to terminal users, and various contents are being developed for each mobile carrier.

With the development of such diverse contents, the mobile communication market has exploded, and in 1999, the number of wireless subscribers has surpassed wired subscribers. This is the result of combining the convenience of mobile communication, which enables communication anytime and anywhere, regardless of time and place, the decrease of equipment price due to technology development, and the increase of people's purchasing power due to economic growth. Compared to providing only simple voice call function, recently, various service functions including short message service have been added, and the usage is greatly increased. Also, wired internet service that has brought social and economic change to the information communication revolution is called mobile communication terminal. Efforts have been made to provide at.

As a result, wireless Internet service represented by WAP has emerged and is rapidly developing and emerging as a technology that will lead the future mobile communication. Wireless Internet, which has been introduced in Korea since 1999, increased by 460% to 2.64 million subscribers at the end of February 2000, reaching 460%. It is becoming a major technology sector of 3G mobile communication service.

Here, the wireless Internet is roughly distinguished from the wired internet used by connecting a wire such as a telephone line or a dedicated line to a computer, and collectively refers to using an Internet service using a wireless terminal or a wireless modem without a wire.

At present, the representative public transportation in our country is bus and subway. The subway operates at regular intervals and keeps accurate time except in special cases. Although it does not run more precisely or at regular time intervals, it has the advantage of operating in areas where the subway does not travel, but there are vulnerabilities that passengers using the bus may have a difficult experience when congested due to limited road conditions.

However, most bus passengers are often confused about the traffic conditions of the bus they ride, whether they have to wait for the bus they want to board, or whether they need to take a taxi to keep their appointments.

An object of the present invention is to solve the problems in using the bus as described above, a bus that can maximize the convenience of passengers using the bus by the mobile terminal users know the state of the bus that they want to use To provide an information guide system.

According to an aspect of the present invention for achieving the above object, the GPS receiver for determining the location information from the location information data transmitted from the GPS satellite and wirelessly present the current state information data including the location information data determined by the GPS receiver A bus having a wireless modem transmitting to a communication network, a wireless communication network transmitting current state information data of the bus transmitted from the wireless modem to a bus information management server, and a current state information data of the bus transmitted from the wireless communication network. A bus information management server for updating, storing and analyzing current state information of the buses, processing the stored data to manage current state information data of the bus, and requesting current state information of the bus to a general mobile communication network. A mobile terminal configured to receive information about the current state of the bus requested by the mobile terminal. And a mobile communication network for requesting the bus information management server through the Internet and providing the transmitted information to the mobile terminal when the requested information is transmitted from the bus information management server through the Internet.

Preferably, the current state information data of the bus transmitted from the wireless modem to the wireless communication network includes an identifier for identifying the buses, one or more of a current position of the buses and a current running speed, and the bus information The current status information data of the management server includes at least one of a bus company and a bus stop according to the bus identification number, a route map, a next bus arrival time, and a next bus estimated time for a stop.

And a web gateway connected to the Internet between the Internet and the mobile communication network, a network interworking device connected to the mobile communication network, and a swapping gateway configured between the web server and the network interworking device, The current status information includes the origin, bus number, and destination.
