On the other hand, the wireless mobile communication technology of the conventional vehicle burglar alarm system as described above generally uses the CDMA mobile communication method based on the IS-95, 95A standard.

The CDMA mobile communication system based on the IS-95 and 95A standards has been developed mainly for voice communication, but now wireless mobile communication technology has developed and the demand for voice communication market is rapidly increasing to high speed data service. Transition is required.

Of course, data service up to 13.35Kbps is possible even under IS-95A standard, but it is very low speed for basic data service. Accordingly, IS-95B and IS-95C are the direction of CDMA standard evolution that intends to provide high speed data service while maintaining part of IS-95A CDMA system and maintaining compatibility with existing IS-95A.

Based on the IS-95A, the data rate of the data service in the CDMA method is the same as the voice coding rate of the call channel. Therefore, data is sent and received at a low rate of 8.6 Kbps in Rate Set 1 and 13.35Kbps in Rate Set 2.

Basically, IS-95B is the standard to increase this low transmission speed up to 8 times while maintaining the basis of IS-95A system. It is not necessary to change the base station's H / W for high-speed data transmission, but it is necessary to change the function of the modem chip of the mobile station and to change the H / W related to the call processing of the control station (BSC). In addition, the IS-95B standard stipulates that problems and inefficiencies in the IS-95A standard can be improved by changing the S / W without changing the H / W as much as possible.

In IS-95B, 8 communication channels can be used simultaneously. Therefore, at rate set 1, a maximum speed of 68.8 Kbps is possible, and at rate set 2, a maximum of 106.8 Kbps is possible.

IS-95C is a method of implementing high-speed data communication by resolving a large part of ISc-95A's Common Air Interface (CAI) standard, which is mainly used for voice communication, to solve capacity problems for data services. 95C.

The problem with data services under the IS-95A specification is that not only low data rates but also packet data transmission in the air are not possible. That is, once connected, whether or not data is transmitted, it causes one call resource and the corresponding noise. As a result, it is impossible to implement economical data services.

This problem is particularly acute with the IS-95B, which uses multiple call channels simultaneously. Therefore, the IS-95B standard stipulates that simple packet data service is possible by temporarily removing some call channel assignments by switching to Dormant state when data transmission does not occur for a while.

In addition, in case of Simple IP in the existing network, data transmission and reception was impossible without leaving the zone, but in the IS-95C, the mobility of the terminal can be guaranteed by adding a mobile IP function similar to the handoff.

Mobile IP users can use their existing IP address to download data from outside their home network. The other party also needs to establish a connection only with the existing IP address of the terminal without knowing where the terminal is located. In other words, the mobile IP is a protocol that detects the movement of the terminal and allows the network after the movement to communicate as in the network before the movement.

Accordingly, an object of the present invention is to provide a next generation vehicle burglar alarm system by applying the IS-95C-based mobile IP data reception function to a conventional vehicle burglar alarm system.

If described in detail the operation and effect of the vehicle anti-theft system using a mobile IP according to the present invention configured as described above.

First, the vehicle terminal 100 and the owner terminal 300 installed in each vehicle are assigned a respective mobile IP address and maintain a communication relationship with the mobile IP wireless communication system, thereby moving the basic communication procedures required for the mobile IP. A location detection procedure of a terminal, a location registration procedure of a mobile terminal, and a packet transmission procedure to a mobile network are performed.

In mobile IP, this communication procedure is performed using a mobile agent. The mobile agent is a home agent 260 connected to the home network of the vehicle terminal 100 and the borrower terminal 300 and an external agent connected to the visited network of the vehicle terminal 100 and the borrower terminal 300. 230).

The alarm procedure of the burglar alarm system according to the interworking between the vehicle terminal 100, the mobile IP wireless system 200, and the vehicle owner terminal 300 will be described with reference to FIG. 3.

First, the vehicle terminal 100 and the owner terminal 300 leaving the home network and request the new IP address (Care of Address) to the external agent 230 belonging to the visited network (S1). Then, the external agent 230 checks whether the new IP address can be allocated, allocates the new IP address to the vehicle terminal 100 and the owner terminal 300, and records the new IP address in its list (S2). In addition, the new IP address is transmitted to the home agent 260 of the vehicle terminal 100 and the owner terminal 300 (S3). The home agent 260 receiving the message may detect the positions of the vehicle terminal 100 and the owner terminal 300 by recording new IP addresses of the vehicle terminal 100 and the owner terminal 300 in its list. (S4).

The terminal 300 transmits to the external agent 230 to which it currently belongs (S7).

After receiving the packet, the external agent 230 checks the actual IP address of the vehicle terminal 100 and the owner terminal 300 remaining after deleting the address added from the packet and transmits the actual IP address to the corresponding terminal (S8). When transmitting to the other party from the vehicle terminal 100 and the owner terminal 300 is sent directly through the external agent 230 without going through the home agent 260 using its actual IP address.

The vehicle terminal 100 and the vehicle owner terminal 300 determine whether the stolen facts are received from the received packet data and alert theft or monitor the vehicle state information (S9).

With reference to Figure 4 looks at the vehicle state monitoring process of the vehicle owner terminal according to the present invention.

First, the vehicle state monitoring mode is selected from among the service modes of the vehicle owner terminal and executed (S11). The borrower terminal transmits its mobile IP information to the mobile IP wireless communication system according to the processing stored in its operation program and requests allocation of a communication channel (S12). In the mobile IP wireless communication system 200, after receiving the vehicle terminal IP address and vehicle status inquiry request information from the vehicle owner terminal 300, the mobile terminal 100 refers to the IP address information of the vehicle terminal registered in the home agent. It tracks the location and allocates a call channel between the owner terminal 300 and the vehicle terminal 100 through an external agent to which the vehicle terminal 100 belongs. If the vehicle terminal 300 is allocated a communication channel from the mobile IP wireless communication system and connected with the vehicle terminal, the vehicle terminal 300 requests to transmit vehicle state information (S13). When the vehicle state information is received from the vehicle terminal, it is analyzed and the analysis result is displayed on the display unit of the owner terminal (S14). For example, the current position of the vehicle, the operation state of the vehicle, and safety checks may be displayed.

After reading the vehicle state information, the owner can remotely operate the vehicle by transmitting a vehicle operation signal such as starting up the vehicle in advance (S15).

Referring to Figure 5 will be described the processing flow for the occurrence of theft situation of the vehicle terminal according to the present invention.

When a signal indicating that a theft condition is generated from the theft detection system installed in the vehicle is detected (S21), the vehicle state information transmitted from the theft detection system is stored (S22).

Subsequently, the BD searches for the borrower's mobile IP address and transmits the borrower's mobile IP address information to contact his mobile IP address information to the mobile IP wireless communication system (S23).

When the communication channel is allocated in the mobile IP wireless communication system, the theft generation signal is transmitted to the borrower's mobile IP terminal and vehicle state information data is transmitted (S24). Waiting for the reception of the vehicle operation signal from the vehicle owner terminal (S25), when the vehicle operation signal is received, the vehicle operation signal is transmitted to the theft detection system of the vehicle (S26). The theft detection system performs the operation of the vehicle according to the vehicle operation signal.

Referring to Figure 6 will be described the flow of processing for the occurrence of theft situation of the borrower terminal according to the present invention.

When the borrower terminal receives any data signal, it checks the mobile IP address of the incoming data signal (S31). Search whether the mobile IP address is a mobile IP address registered in the anti-theft program (S32), and if the mobile IP address is registered, start the anti-theft program, analyze the incoming signal message, and generate a corresponding theft alarm. (S33).

By generating the theft alarm, the owner notifies the vehicle of theft, and requests the vehicle terminal information of the vehicle (S34). When vehicle status information is received from the vehicle terminal (S35), when the vehicle information is received, the current state of the vehicle is detected, the vehicle operation signal is generated accordingly, and the vehicle operation signal is transmitted to the mobile IP vehicle terminal to execute the operation of the vehicle according to theft. (S36).

If the mobile IP address of the first incoming data is not the mobile IP address registered in the anti-theft program, the general incoming signal processing program is operated to perform a general call service procedure (S37).

According to the present invention, the IS-95C-based mobile IP data receiving function can be used in conjunction with a vehicle theft alarm system, so that the owner can use his mobile IP network by the development of communication environment more accurately and quickly. By monitoring the vehicle status information or transmitting the vehicle operation signal, the vehicle can be controlled remotely, and the mobile IP address assigned to the mobile IP vehicle terminal installed in the vehicle can be known when the vehicle is stolen. Even after theft, it can be a great help in collecting vehicles.
