## Abstract

A system for notifying of arrival at a subway station and providing station information by using integrated smartphone positioning includes: a providing system 11 connected to a user terminal 12 through a network; and the user terminal including a current location identifying module 21, a path generating module 22, a boarding identifying module 23, an advertisement providing module 24, a stop station guidance module 25, and a sensor unit 27 having a plurality of sensors. The providing system 11 includes a sensing pattern information DB 31 storing information repeatedly sensed by the plurality of sensors at a predetermined location. The current location identifying module 21 determines the current location of the user terminal 12. The stop station guidance module 25 provides, to the user terminal 12, information about a nonstop station and about arrival at an arrival station on a real-time basis.

## Claims

### Claim 1

A system for notifying of arrival at a subway station and providing station information by using integrated smartphone positioning comprising:
a providing system 11 connected to a user terminal 12 through a network; and
the user terminal including a current location identifying module 21, a path generating module 22, a boarding identifying module 23, an advertisement providing module 24, a stop station guidance module 25, and a sensor unit 27 having a plurality of sensors,
wherein the providing system 11 includes a sensing pattern information DB 31 storing information repeatedly sensed by the plurality of sensors at a predetermined location, the current location identifying module 21 compares the information sensed by the sensor unit 27 with sensing information stored in the sensing pattern information DB 31 to determine the current location of the user terminal 12, and the stop station guidance module 25 determines a direction where a user heads according to the location of a platform on which the user boards a subway when the current location is determined, receives, from a subway line map DB 32, information about a next station and about a predicted time of arrival at the next station, and provides, to the user terminal 12, information about a nonstop station and about arrival at an arrival station on a real-time basis.

### Claim 2 (depends on 1)

The system of claim 1, wherein the plurality of sensors of the sensor unit include two or more of a Wi-Fi module, a Bluetooth module, a geomagnetic sensor, a barometer, a magnetic sensor, an acceleration sensor, and a gyro sensor.

### Claim 3 (depends on 2)

The system of claim 2, wherein spots at which the sensed information is stored in the sensing pattern information DB 31 include an up platform, a down platform, a ticket barrier, and an entrance of a station.

### Claim 4 (depends on 3)

The system of claim 3, wherein the interior of the station is divided into a plurality of zones having a certain size, and the providing system 11 determines at least one place of boundary lines and centers of the individual zones, obtains an average value and a standard deviation value by repeatedly measuring the sensing information at the determined at least one place, and stores the obtained average value and standard deviation value in the sensing pattern information DB 31.

### Claim 5 (depends on 3)

The system of claim 3, wherein the interior of the station is divided into a plurality of spots, the providing system 11 collects sensing pattern information at the respective spots, stores an advertisement designated at each spot in an advertisement DB, and provides a different advertisement to the user at each spot, and
wherein the providing system 11 provides a different advertisement to the user according to a spot suitable for the user.

### Claim 6 (depends on 5)

The system of claim 5, wherein the sensing pattern information DB 31 is configured in the form of a neural network which learns data using location values (x, y, w) of the station as output values and using sensed values sensed by the plurality of sensors at a corresponding location as input values, and the providing system 11 provides a predicted location value as an output value to the user terminal through the neural network having learned the data when receiving a sensed value, and wherein by allowing the neural network to learn the data while inputting an output value of at least one adjacent spot as an input value to a spot to learn the data at the time of the learning, the sensing pattern information DB 31 allows the neural network to also learn an influence caused by the proximity.

### Claim 7 (depends on 4)

The system of claim 4, wherein the path generating module 22 stores the information sensed by the user terminal 12 in a moving history storage information DB 33 at regular time intervals, and generates the user's moving path from the stored information, and the boarding identifying module 23 identifies that the user boards the subway from the generated user's moving path and currently sensed information such that the stop station guidance module 25 starts to provide guidance on a stop station.

### Claim 8 (depends on 7)

The system of claim 7, wherein the advertisement providing module 24 receives, from the advertisement DB storing a preferred location together with the advertisement, an advertisement requested by the user terminal at the preferred location when the user terminal is located at the preferred location, and provides the received advertisement to the user terminal.
