Description

Wireless terminal registration and authentication method in home base station of digital wireless telephone system

The present invention relates to a method for registering and authenticating a next-generation digital cordless telephone (hereinafter referred to as a "wireless terminal") in a next-generation digital wireless telephone system. In particular, the present invention provides a method for preventing redundant misuse of a wireless terminal using another base station. It relates to a registration and authentication method of a wireless terminal.

In general, the digital radiotelephone system includes a radio base station called a telepoint and a radio terminal for forming a call path through the radio base station.

In the digital radiotelephone system, three types of public mode, home mode, and operator mode (PABX mode) are used depending on the purpose.

Public mode is used in connection with a Public Switched Telephone Network (PSTN) through a public base station (Telepoint), which is connected to a public telephone on a city street. In order to make a call in the public mode, a radio terminal attempts to make a call by transmitting a call request signal to the public base station. Then, in response, a channel is allocated from the public base station and forms a call path by a predetermined protocol. The operator mode is operated in the same manner as the public mode, and the other thing from the user's point of view is that it is used in connection with a wireless private exchange (PABX) including a telepoint, not a PSTN network. In addition, the home mode is connected to the PSTN network through a home wireless telephone (hereinafter, referred to as a "home base station") containing a telepoint to form a communication path.

In the charging system of the digital radiotelephone system, in the public mode and the operator mode, there is a predetermined charging system added by the same service system. However, in the home mode, it is operated according to the charging system of the general telephone, unlike the charging system of the public or operator base station.

In the wireless terminal registration method, registration can be performed only by the system administrator in the public mode and the operator mode. However, in the home mode, when both the home base station and the wireless terminal are in the registration mode, registration can be performed by a predetermined protocol. 1 is a diagram illustrating a connection between a wireless terminal and a home base station in a general digital wireless telephone system, which will be described in detail with reference to the drawing.

Reference numerals 200 and 201 in the drawings refer to the same billing system, that is, a home base station used in one home, and 60 and 60-1 are their CT2 terminals registered in the home base stations 200 and 201. The 60 and 60-1 should be registered in the two home base stations 200 and 201, even if the same billing system is used. The wireless terminal 60 and the wireless terminal 60-1 may form a wireless link through the home base station 200 and make a call through a public switched telephone network (PSTN).

And reference numeral 300-1 in the drawings is a wireless terminal using a home base station 300 having a different charge system from the home base station 200. The wireless terminal 300-1 may form a call path through the home base station 300, and may not form a call path through the home base station 200. However, if the user of the wireless terminal 300-1 sets the wireless terminal 300-1 to the registration mode and the home base station 200 is set to the registration mode with the slot selected, the user may set the wireless terminal 300-1 according to a predetermined protocol. The wireless terminal 300-1 may be registered in the home base station 200.

As described above, it is easy to register another wireless terminal in addition to its own wireless terminal in the home base station. Therefore, there is a problem that other people who do not know the user using the home base station can illegally register and use the service within 200 meters, so that the user must pay even for a telephone charge not used.

In addition, when a call is received, a wireless terminal registered illegally can receive it, which causes a problem invading privacy.

Accordingly, an object of the present invention is to provide a wireless terminal registration and authentication method for preventing duplicate misuse by illegal registration of another wireless terminal other than its own wireless terminal in one home base station.

In order to achieve the above object, the present invention includes a home base station having a memory storing a group identification number, a base station identification number and a password, and a second memory for storing information on a registration slot including a group identification number. In the method of registering a wireless terminal in a home base station of a digital wireless telephone system consisting of a wireless terminal, the home base station receives a predetermined key input, sets the wireless terminal registration mode, and reads out the identification number, base station identification number, and password to authenticate the wireless terminal. A first process of configuring data and transmitting the data to the wireless terminal and setting the home terminal to a home base station registration mode by receiving a predetermined key input, and determining whether to authenticate the wireless terminal when a slot is selected in the registration mode. Next, if the wireless terminal is authenticated the authentication data And after storing in the second memory, a second process of transmitting the wireless terminal identification code, and a third process of receiving the wireless terminal identification code transmitted from the wireless terminal and storing it in the memory. It is done.

When a predetermined key is input from the first key input unit 35, the controller 10 switches to the group identification number setting mode in step 401. The control unit 10 then proceeds to step 403 and displays a message requesting the group display number to be input to the first display unit 40. If the message is displayed, the controller 10 proceeds to step 405 and checks whether a group identification number is input. In this case, when a group identification number is input from the first key input unit 35, the control unit 10 proceeds to step 407 and stores the group identification number in the memory 20. The group identification number may be set to a predetermined digit by a combination of numbers, special characters, and the like in the key input unit 35. The group identification number is set when there is more than one home base station, and it does not need to be set when there is one.

FIG. 5 is a flowchart illustrating a wireless terminal registration process in a home base station according to an embodiment of the present invention. Referring to FIG. 1, the wireless terminal 60 is registered in the home base station 200 in FIG. A case where the terminal 60-1 is registered with the home base station 200 will be described.

First, in order to register the wireless terminal 60-1 with the home base station 200, the home base station 200 and the wireless terminal 60-1 enter the wireless terminal registration mode and the home base station registration mode in steps 501 and 531, respectively. Should be set.

When a predetermined key is input from the first key input unit 35, the first control unit 10 of the home base station 200 switches to the wireless terminal registration mode in step 531, and the group identification number and the base station identification number from the memory 20. Read and password to compose authentication data. Then, the first controller 10 periodically transmits the authentication data to the second controller 51 in step 533. Then, the second controller 51 receives the authentication data and transmits the authentication data through the signal processor 55 and the RF unit 53.

When the wireless terminal 60-1 is set to the home base station registration mode in step 501, the third controller 61 of the wireless terminal 60-1 displays the initial slot on the display unit 64 in step 503, and then selects a predetermined slot. Check if the slot is selected by key input. Typically, the wireless terminal 60-1 has 6 to 10 slots for home base station registration, and 4 slots for public base stations. If one of the home base station slots is selected in step 503, the third controller 61 proceeds to step 505 and checks whether authentication data is received. If the authentication data is input through the antenna, the second RF unit 65 and the second signal processing unit 66 during the inspection, the third control unit 61 temporarily stores it in the RAM, and proceeds to step 507 to store the second password message. Displayed on the display unit 64. Then, the third control unit 61 checks whether a password is input from the second key input unit 63. The password is a number based on a combination of numeric keys and special character keys. When the password is input during the password input check, the third controller 10 compares the password input from the second key input unit 63 with the password included in the authentication data to determine whether the password is the same and performs the authentication process. do. If the inputted password is authenticated, the third controller 61 proceeds to step 513 and searches for the previously registered slot by searching the second memory 62. If there is a slot registered in the memory, the third controller 61 proceeds to step 515 and compares the group identification number of the slot with the group identification number included in the authentication data to determine whether the slot is the same. As a result of the determination, if the previous group identification number and the group identification number included in the authentication data are the same, a registration success message is displayed on the second display unit 64, and the flow proceeds to step 519 to transfer the authentication data to the second memory 62. Save it. When the authentication data is stored, the third controller 61 transmits the wireless terminal identification code to the home base station 200 in step 521. The wireless terminal identification code is a serial number unique to the wireless terminal 60.

The first control unit 10 of the home base station 200 checks whether the wireless terminal identification code is received from the wireless terminal 60 after transmitting authentication data in step 533. When the wireless terminal identification code is received during the inspection, the first control unit 10 stores the memory 20 in step 537.

6 is a flowchart illustrating a wireless terminal authentication method in a home base station according to an embodiment of the present invention.

Hereinafter, referring to FIG. 6, first, in step 601, the third control unit 61 of the wireless terminal 60 searches for the second key input unit 63 and checks whether a transmission is attempted. When the transmission is attempted in step 601, the third controller 61 reads authentication data from the second memory 62, and transmits the authentication data to the antenna via the second signal processing unit 66 and the second RF unit 65. ANT2) to the home base station 200.

In operation 611, the first control unit 10 of the home base station 200 periodically checks whether authentication data is received. In this case, when the authentication data is received from the wireless terminal 60, the first controller 10 proceeds to step 613 to compare the group identification number of the received authentication data with the group identification number stored in the memory 20. An authentication process is performed to determine whether it is the same. When the group identification number received in the authentication process is authenticated, the first controller 10 performs a base station identification number authentication process in step 515. The base station identification number authentication process is a process of comparing the base station identification number of the received authentication data with the base station identification number preset in the memory 20 to determine whether the same. If the base station identification number received in step 515 is authenticated, the first controller 10 proceeds to step 617 to perform a password authentication process. The password authentication process is determined by comparing the password of the received authentication data with the password previously stored in the memory 20. If the password is authenticated in step 617, the first controller 10 proceeds to step 619 to control the dialing unit 30 to generate a multiplex signal for the dialing number received from the wireless terminal 60. The multiplex signal is input to the public switched telephone station 70 and switched to the subscriber communication terminal 71 to form a call with the wireless terminal 60. On the other hand, if it is not authenticated in any one of the group authentication process, the base station authentication process, and the password authentication process, the call formation failure signal is transmitted through the second control unit 51, the signal processing unit 55, and the RF unit 53 through the antenna ( ANT1) to the radio terminal 60.

The third control unit 61 of the wireless terminal 60 checks whether a call is established in step 605 after transmitting authentication data in step 603. At this time, if a call formation signal is received from the home base station 200, the call is initiated. However, when the call establishment failure signal is received, the third controller 61 displays the call establishment failure message on the display unit 64 in step 607 and terminates the transmission.

As described above, the present invention has an advantage of preventing a wrong billing system on multiple registrations generated on a protocol by further adding a group identification number and a password authentication process.
