Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency rescue method using location registration of a neighboring terminal,

The present invention relates to an emergency relief method, and more particularly, to an emergency relief method capable of estimating a position of a user by detecting position information of a terminal adjacent to the user terminal and turning off the power of the user terminal.

A communication terminal such as a mobile phone registers its position with the corresponding base station exchange from time to time. When a call comes in, the communication terminal is connected to the telephone via the base station that has registered the terminal information of the corresponding location.

BACKGROUND ART [0002] Recently, communication terminals such as a smart phone have become popular among most users. In addition, in order to make a telephone call when moving outside, a user must always carry one or more communication terminals. Mobile communication terminals such as mobile phones and PDAs are regarded as essential necessities for the adult society.

On the other hand, when an imminent or dangerous situation occurs, the user can contact the outside through voice communication using the mobile communication terminal. However, in a situation such as a kidnapping where the user feels threat to the user, there is a problem that it is difficult to inform the user of his / her situation through a voice call.

Even if a voice call is made after the user sends an emergency signal, it is difficult to explain the detailed situation such as the current position and surrounding persons. Making a voice call by contacting a police station in a dangerous situation, such as kidnapping, may result in a more dangerous situation for the user.

The mobile communication terminal registers location information by the base station in the area. Such location information can be used in the relief of the user in an emergency. However, when the user's communication terminal is turned off, the location information can not be received from the base station because the user terminal can not receive the registered location information.

Particularly, in a situation such as a kidnapping, the criminals generally confiscate the user's communication terminal and turn it off. Considering this, the current position tracking technology is not suitable for user relief in an emergency situation.

Therefore, even if the power of the communication terminal of the current user is turned off, there is a need for an accident countermeasure capable of tracking the position of the user and making an emergency call.

Korean Patent Publication No. 2003-0075938

Accordingly, the present invention provides an emergency relief method capable of relieving a user by estimating the position of a user terminal even when the power of the user terminal is turned off.

According to an aspect of the present invention, there is provided an emergency relief method using location registration of a neighboring terminal adjacent to a specific terminal, the method comprising: requesting encrypted identification information of a neighboring terminal; Receiving encrypted identification information from a neighboring terminal according to a request for identification information in a local area communication method; And transmitting its identification information and encrypted identification information of the received neighboring terminal to the base station.

Preferably, the emergency relief method according to the present invention may further include a step of receiving a plurality of pieces of the encrypted identification information to determine a neighboring terminal having a strongest received signal strength. In this case, the encrypted identification information of the transmitting neighboring terminal is preferably the encrypted identification information of the neighboring terminal having the largest received signal strength.

According to another aspect of the present invention, there is provided an emergency relief method using location registration of a neighboring terminal, comprising: receiving, encrypting and transmitting identification information of a terminal; Receiving identification information of a specific terminal from a specific terminal and encrypted identification information of a neighboring terminal adjacent to the specific terminal; Decrypting the encrypted identification information; And storing the identification information of the specific terminal and the decoded identification information of the neighboring terminal for the specific terminal. In this case, the encrypted identification information to be received may be plural.

According to the present invention, since the location information of the neighboring terminal is registered together with the location information of the specific terminal in the process of communicating with the base station, the location of the specific terminal can be estimated through the location information of the adjacent terminal even when the power of the specific terminal is turned off. There is an advantage.

1 is a conceptual diagram of an emergency relief system according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the exemplary embodiments. Like reference numerals in the drawings denote members performing substantially the same function.

The objects and effects of the present invention can be understood or clarified naturally by the following description, and the purpose and effect of the present invention are not limited by the following description.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Generally, the location registration procedure of the communication terminal is as follows. When the power is turned on, the communication terminal transmits a MIN (Mobile Identification Number), which is an identification number, and an ESN (Electronic Serial Number) message, which is a terminal unique number, to a nearby base station. The base station transmits the received information to the exchange. At this time, the exchange compares the received MIN with all the MINs in the network to determine whether the corresponding communication terminal is located at the home exchange station or the visitor exchange. If the communication terminal is outside, the exchange sends a message to the home location register (HLR) to which the subscriber belongs using the routing information (tracking route) stored in the signaling transfer point (STP).

The HLR receives the message and confirms whether the number is valid by using MIN and ESN, and then registers the location information. After registering the location information of the communication terminal, the HLR transmits information of the terminal to the external visited exchange. The external visiting exchange receives the information of the terminal and stores it in a Visitor Location Register (VLR), which is a visitor location register.

1 is a conceptual diagram of an emergency relief system 1 according to an embodiment of the present invention. Referring to FIG. 1, the emergency relief system 1 may be configured such that when the base station 10 registers the location information of a specific terminal 31, the location information of the neighboring terminals 32 and 33 is registered together.

In the following description, a terminal of a user who wishes to estimate a position even when the power is turned off is referred to as a specific terminal 31 and a terminal located at a distance that enables short-range wireless communication with the specific terminal 31 is referred to as a neighboring terminal 32 or 33 do. In the following description, MIN and ESN information of a terminal is referred to as identification information.

The emergency relief method according to the emergency relief system 1 includes the steps of the base station 10 receiving the identification information of the terminals 31, 32 and 33; The base station 10 encrypting the identification information of the received terminal 31, 32, 33; Transmitting the encrypted identification information to each of the terminals (31, 32, 33) by the base station (10); Receiving the encrypted identification information of the neighboring terminal (32, 33) from the specific terminal (32) of the base station (10); Decrypting the encrypted identification information received by the base station 10; And storing the identification information of the neighboring terminal 32, 33 decoded by the base station 10.

In the emergency relief method according to the present embodiment, unique identification information of adjacent user terminals 32 and 33 must be received from a specific terminal 31. Therefore, the identification information of other users needs to be encrypted. Although not shown in the figure, the base station 10 may include a processor for receiving the identification information of the terminals 31, 32 and 33 and then encrypting the identification information of the received terminals 31, 32 and 33.

In the present embodiment, the encryption of the identification information may be performed by a method in which a virtual code is assigned to each identification information using a virtual IP granting scheme used in the Internet protocol. Although not shown in the figure, the base station 10 may have a separate database to map the identification information of the terminals 31, 32, and 33 and the encrypted virtual codes of each identification information.
