Description

Machine-to-machine communication system utilizing personal mobile phone provided with blutus communication function}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication service system of a machine to machine (hereinafter, referred to as 'M2M'), and in particular, an individual portable communication terminal carrying a connection device of a mobile communication network used as a communication path. Through mobile phones, cellular phones, smart phones, personal digital assistants, etc., hereinafter referred to as 'mobile phones', mobile phones equipped with Bluetooth communication function (internal or external) (hereinafter referred to as 'Bluetooth phones') M2M terminal for collecting information such as various sensor signals, video and audio data, and M2M communication system for forming a communication path between the management server of the control center for analyzing and managing the collected information.

Generally speaking, the term M2M is short for "Machine to Machine", which literally means that machines communicate with each other, and the concept of communication between people is possible. Is a concept that extends to and from people.

In simple terms, it is possible to attach a communication device (modem) to a machine that grasps the state of the surrounding environment, and send and receive the specified information according to specific conditions with the management server of the remote control center. Collectively referred to as a series of systems to perform.

Such M2M system is easily applied in our daily life due to the development of electronics and communication technology, and its range is gradually expanding. A representative example thereof is a CCTV system as shown in FIG. have.

The CCTV system of the M2M method shown in FIG. 1 includes a plurality of M2M terminals within a certain monitoring range, and is connected to a management server of a control center through at least one wired or wireless Internet access device. The M2M terminal is connected to a specific device with a sensor function, and can send information to the management server of the control center through a built-in communication function when a certain time unit or event occurs according to the information collected by the sensor. The service provider can access the management server to monitor and control the status of the M2M single-header and the surrounding environment.

The system of the M2M system is not limited to the example of FIG. 1 attached thereto, but various information collected from sensors, cameras, microphones, and the like mounted on the M2M terminal according to the application object and the application method may be remotely connected through various types of communication means. It can reach the management server of the service provider in.

In addition, a method for transmitting information collected from an M2M terminal to a remote management server was initially limited to using a wired communication network such as an existing dedicated line or a wired internet, but recently, a wired network must be connected to a communication unit of an M2M terminal. M2M systems using wireless communication networks are increasing due to the advantages of avoiding inconvenience and expanding services to areas where wired networks cannot be installed.

The wireless communication network that can be used in the M2M system can be divided into wireless LAN, CDMA, and portable Internet (eg WiBro) according to the technology. Since WLANs can only communicate within a certain distance from where fixed access points (AP Access Points) are installed, they are suitable for services where M2M terminals are installed at fixed locations, but the location of M2M terminals is constantly changing. There are drawbacks to using services.

After all, in the case of a service that changes the location of the M2M terminal by continuously moving, such as a portable healthcare device, a vehicle black box, as shown in Figure 2 attached to a wireless mobile communication such as CDMA or Wibro (hereinafter referred to as 'mobile communication' Network). Until now, mobile communication modems such as CDMA or WiBro modems are used inside or outside the M2M terminal to use the mobile communication network for communication between the management server and the M2M terminal such as portable healthcare device and vehicle black box. Equipped with a BTS Base Transceiver Station has been transmitting and receiving data.

However, the mobile communication modem such as a CDMA or WiBro modem is mounted on the M2M terminal for communication between the management server and the M2M terminal such as a portable healthcare device, a car black box, etc., and a base station (BTS Base Transceiver Station) of the mobile communication network. The method of transmitting / receiving data has the advantage of easy development and high usability. However, in order to access a mobile network, an expensive CDMA or WiBro modem must be added to the M2M terminal, and a monthly network fee is paid to the network operator to use the mobile network. There is a problem that must be done.

As a result, such a high cost structure has become a major obstacle to the proliferation of M2M services using mobile communication networks.

As expected effects due to the above-described features of the present invention, the M2M terminal for collecting various mechanical signals and data such as various sensor signals, video and audio data, and the management of the control center for analyzing and managing the collected data (signals) The M2M terminal realizes communication with the mobile communication network by utilizing the Bluetooth phone that the user carries as an external mobile communication modem of the M2M terminal, without separately installing the mobile communication modem necessary for transmitting and receiving data between servers. This eliminates the need to install an expensive mobile communication modem, which can lower the production cost of the M2M terminal and pay monthly by sharing the mobile communication network to which the existing Bluetooth phone is subscribed without a separate mobile communication network for the M2M terminal. It is possible to reduce the separate mobile network usage fee.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

In detail, the reason why the M2M system is needed to apply to a moving object pointed out as the above-mentioned problem is that when a person who has a serious car accident is known, the response time of an emergency rescue worker becomes a matter of life or death once an accident occurs. Can be. Rapid arrival of emergency rescue personnel can increase the chances of survival even for seriously injured persons. On the other hand, delays in notification to relevant agencies significantly reduce the likelihood of survival.

Besides the response time, the accuracy of the information is also important. In other words, it is important that emergency responders know the type of accident that occurred and make appropriate emergency equipment available. For example, an ambulance may suffice for a person shocked. However, people trapped in seriously damaged vehicles and bleeding heavily will need additional equipment, including helicopters and lifesaving cutters. As a result, it is essential to clarify the level of injury before dispatching emergency rescue equipment.

In many accidents, motorists can become unconscious, which means that motorists cannot explain the situation or scene of the accident. Vehicular navigation systems such as OnStar ^™ can relay accident time and accident location immediately, while these systems cannot relay information about the severity or type of accident.

A conventional general solution to this lack of information is to use a "black box" to equip the vehicle with a camera that continuously records video footage, similar to the recorders used on airplanes. These video footage is stored in a fixed collision avoidance, nonvolatile memory device away from the black box. In the event of an accident, the black box freezes the video data stored in the box and optionally sends this data to the central server.

The biggest problem with this conventional solution is that it is expensive, and video cameras must be mounted in a car and record video footage continuously. In addition, a black box is needed to store footage, and such a system would have to add a considerable price to the car's overall price.

In addition, in order to prepare the status of the accident vehicle in real time at the time of the accident at the remote control center without increasing the memory for storing the video data of such a vehicle, as shown in FIG. It is necessary to maintain a communication service for connecting a box or an M2M terminal to a mobile network at all times. Such a mechanical expense and a burden of communication costs cause the consumer to be prepared for the countermeasure of a safety accident.

Therefore, in the present invention, a mobile communication modem (CDMA or WiBro) of a Bluetooth phone between an M2M terminal collecting various mechanical information such as various sensor signals, video and audio data and a management server analyzing and managing the collected information. And if the communication using the hardware and software functions of Bluetooth properly, the M2M terminal alone will be able to significantly reduce the production cost and communication costs required to wirelessly communicate with the mobile communication network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Attached Figure 3 is an exemplary view for explaining the concept of a device-to-device communication system using a personal portable communication terminal with a Bluetooth communication function according to the present invention as a communication module, such as a LAN card that the existing M2M terminal was provided as a Bluetooth communication module After replacement, a communication channel is established with the user's Bluetooth phone through the Bluetooth function of the user's Bluetooth phone.

The data received by the Bluetooth phone from the M2M terminal through the Bluetooth communication channel should be transmitted in real time to the BTS Base Transceiver Station of the mobile communication network to which the Bluetooth phone is subscribed without interruption. Change or add internal software.

The data transmitted to the base transceiver station (BTS) of the mobile communication network must be transmitted to the management server of the control center in real time through the communication server provided by the mobile network operator, and the software for this is added to the communication server or the management server. do.

The data received from the M2M terminal via the Bluetooth phone and through the mobile communication network is transmitted to the management server of the control center for analysis and processing.
