Description

Method of limiting transmission function of mobile wireless terminal using short message transmission {METHOD FOR LIMITING CALL OF MOBILE WIRELESS TERMINAL USING SHORT MESSAGE SERVICE}

The present invention relates to a mobile wireless terminal, and more particularly, to a mobile wireless terminal capable of using a short message service (SMS).

Recently, the wireless Internet as an extension of the Internet is coming. The development of various services in the wireless Internet is taking place faster than expected based on the already developed wired internet. The vitalization of the Internet and the development of mobile communication technology have shown the possibility of using the mobile wireless terminal as a necessity of human life in the information age where the internet can be available anytime and anywhere beyond the simple means of communication. The user can freely move to the desired place while maintaining the network connection. Wireless Internet is a sign of the beginning of the Post PC era, which will take place after the information age of the PC era.

Users want to be able to easily access their e-mail, access the Internet, and access personal and corporate information with a mobile wireless terminal. There is also a Wireless Application Protocol (WAP), but one of the things that can be used with this technology is SMS. SMS is a basic service of wireless data communication, and can receive and send texts through a wireless device. Unlike WAP, which is used only when the user's intention is connected to the Internet, SMS can be sent immediately if the other party's mobile phone is on, and can be read and stored like an e-mail. More than 5 billion messages were generated in March 2000, and more than 100 billion SMS will be sent per month within the next three years, and more than 10 billion SMS are expected at the end of 2000. In addition, the introduction of packets such as GPRS, 3G, and Internet browser functions such as WAP have a positive impact on SMS development. In a WAP environment, SMS enables customers not only to download Internet content but also to have voice conversations.

SMS can be applied to various remote control with unique data transmission and reliable transmission guarantee. If you use SMS to support the Internet, 160 bytes is very limited, but SMS is not intended for wireless Internet. However, the method of providing information when the user is in the standby mode, that is, the push function is currently available only for SMS.

In this way, if only the mobile wireless terminal is turned on, it is immediately transmitted. If the transmission is not confirmed, the service of the lost mobile wireless terminal is not stopped by using the characteristic that the message can be delivered by the Store and Forward method. Suggest ways to recover without.

In the past, when a terminal is lost, a request for a stop should be made to the mobile communication provider in order to restrict a person who acquires the terminal from using the mobile terminal arbitrarily. However, such a method can prevent a person who has acquired a terminal from using the terminal arbitrarily, but also restricts a method in which a person who loses the terminal can contact his or her lost terminal. Therefore, if the terminal is lost, the opportunity to simply find the lost terminal is lost by calling its terminal and talking to the person who acquired the terminal.

Accordingly, an object of the present invention is to provide a method for restricting the use of a terminal lost by a user by using a short message service function used by the mobile terminal when the mobile terminal is lost.

Another object of the present invention is that when a user loses a mobile wireless terminal, the user who lost the terminal can use only a short message service communication network to limit the transmission function of the mobile wireless terminal and use the reception function, thereby losing the user's own terminal. The present invention provides a method for enabling a call to a person who has learned and lost his terminal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the reference numerals to the components of the accompanying drawings, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. Also in the following description and in the accompanying drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a system configuration for providing a short message transmission according to the present invention. Referring to Figure 1 will be described the configuration of the system applied to the present invention as follows.

First, the Short Message Service Center (SMSC) 70 is an independent node, which is a Home Location Register (HLR) 68 and a Mobile Switching Center (MSC). In addition, MSC (66) is connected to have a function to determine the location of the recipient to deliver a short message to the mobile subscribers through the Public Land Mobile Network (PLMN). SMSC is able to send and receive numbers and letters in both directions between various text delivery systems (PC communication system, Internet server system, mobile wireless terminal, etc.) and subscribers using mobile communication network, and Short Message Client (not shown) ) To connect to other networks.

The MSC 66 interworks with other MSCs to process outgoing / receiving requests from a mobile station (hereinafter referred to as MS) 50, performs an inquiry to the subscriber with the HLR 68, and performs a short message. Is transmitted from the SMSC 70 to a base station controller (BSC) 64 and transmitted via a paging channel at the base station transceiver subsystem (BST) 62. To be transmitted. Receiving messages in the opposite direction is performed in the same way. The HRL 68 is a medium-class computer that mainly performs subscriber information processing device functions. The HRL 68 is classified into four types: a network access device, a subscriber database, and an operation management device. The BSCs 64 and 72 control the wireless link and the wired link, and perform a handoff function to maintain the continuity of the call while the subscriber is on the move. The BTSs 62 and 74 perform communication using the wireless section together with the MS 50 and the SMS transmission terminal 40.

The short message transmission process through the wireless network 60 is as follows. The MSC 66 receives the short message sent from the SMS transmission terminal 40 through the BTS 62 and the BSC 64. MSC 66 sends the short message to SMSC 70. The SMSC 70 stores the short message received from the MSC 66 in an internal database according to the calling party number. Thereafter, a route query is made to the HRL 68 in order to know the location information of the receiver (lost mobile wireless terminal, hereinafter MS 50). Upon successfully receiving information about the route from the HRL 68, the SMCS 70 attempts to send a short message to the MSC 66 currently connected to the MS 50. If the short message is not properly transmitted because it is not connected to the MS 50, it may be periodically retransmitted. Upon receiving the short message, the MSC 66 transmits the short message to the BSC 72 connected to the MS 50. The BSC 72 sends a short message to the MS 50 via the BTS 74.

The MS 50 is a mobile wireless terminal lost by a user, and is a mobile wireless terminal owned by anyone who has acquired it. The MS 50 transmits / receives a short message from the RF unit 18 of FIG. The MS 50 stores the received short message and transmits the response message to the RF unit 18 via. The process of transmitting the response message to the SMS transmission terminal 40 is the same as the process of transmitting the short message to the MS 50.

2 illustrates an example of a block configuration of a mobile wireless terminal for providing short message transmission according to the present invention. 2, in the mobile wireless telephone to which the present invention is applied, the controller 10 controls the overall operation of the mobile wireless telephone. The memory 16 includes a read only memory (ROM) storing an operating program, an electrically programmable erasable ROM (EEPROM) and a random access memory (RAM). The memory 16 stores an operation program for short message processing of a mobile wireless terminal according to an embodiment of the present invention. In addition, a short message is stored in the Y. pyrom of the memory 16.

The display unit 12 may be a display device such as a liquid crystal display (LCD). The display unit 12 displays the state of the mobile wireless terminal or the progress of the program under the control of the controller 10. The key input unit 14 includes a plurality of numeric keys and function keys for performing various functions, and outputs key input data to the controller 10 according to external key manipulation.

The RF unit 18 up-converts the signal input from the baseband unit 20 under the control of the controller 10 and wirelessly outputs the signal to the base station (not shown) via the antenna ANT. . In addition, the RF unit 18 down-converts the received signal received through the antenna under the control of the controller 10 and outputs the received signal to the baseband unit 20. The baseband unit 20 converts a signal input from the RF unit 18 into a baseband and a digital signal and outputs the signal to the control unit 10. In addition, the baseband unit 20 outputs a signal output from the control unit 10 to the RF unit 18. The controller 10 performs channel demodulating and channel decoding operations on the digital signal output from the baseband unit 20. The control unit 10 displays the data on the display unit 12. The controller 10 outputs the corresponding voice data to the voice processor 22. The voice processor 22 compresses / decompresses the voice data, converts the voice data into an audible voice signal, and outputs the same to the user through a speaker SPK. In addition, the voice signal processor 22 converts and compresses a voice signal of the user output from the microphone MIC into voice data and outputs the voice signal to the controller 10. The controller 10 performs an operation such as channel coding and channel modulation on the voice data, and wirelessly outputs the base station through the baseband unit 20, the RF unit 18, and the antenna. do. In addition, the controller 10 performs a user interface function. That is, the controller 10 displays various menus for user convenience on the display unit 12 so that the user can select the corresponding menu.

According to the present invention, the mobile wireless terminal configured as described above can easily limit the transmission function by using the SMS function. In other words, when the mobile radio terminal receives the transmission function restriction data from the base station, the mobile terminal recognizes the transmission function restriction command from the received data so that only the transmission can be performed.

3 is a control flowchart illustrating a method of limiting a transmission function using a short message service of a mobile wireless terminal according to an embodiment of the present invention.

Hereinafter, a method of limiting a transmission function using a short message service of a mobile wireless terminal applied to the present invention will be described in detail with reference to FIGS. 1 to 3.

The MS 50 of FIG. 1 is a mobile wireless terminal lost by a user, and is a mobile wireless terminal owned by any person who has acquired it. The MS 50 receives the short message from the RF unit 18 of FIG. The control unit 10 of FIG. 2 determines whether a short message is received in step 100 of FIG. 3, and if so, the control unit 10 proceeds to step 102 of FIG. 3. The controller 10 analyzes the short message received in step 102 and proceeds to step 106 of FIG. 3 to determine whether the received short message is a command. The controller 10 proceeds to step 110 when the received short message is a command in step 106 and proceeds to step 108 when the general short message is displayed on the display unit 12 of FIG. 2 and stores it in the memory 16. . Although not shown in FIG. 3 to clarify the flow of the invention, the controller 10 stores the received short message and transmits a response message to the SMS transmission terminal 40 through the RF unit 18. The process of transmitting the response message to the SMS transmission terminal 40 is the same as the process of transmitting the short message to the MS 50.

The controller 10 determines in step 110 whether the received command is a command for limiting the transmission function of the MS 50, and if it is a command for limiting transmission, the control unit 10 proceeds to step 114 to limit the transmission function of the MS 50. On the other hand, if the received command in step 110 is not a command for limiting a transmission function, the controller 10 proceeds to step 112 and performs the corresponding command.

As described above, in order to prevent others who use the mobile wireless terminal lost by the user who has lost the mobile wireless terminal, a command for limiting the transmission function is transmitted using SMS, and the lost terminal is transmitted through SMS. Analyzing the command that limits the transmission function from the short message, it limits the transmission function of the call function of the terminal accordingly. Once the call is restricted, only the transmission becomes impossible, and the method of restoring again can restore the transmission so that transmission is possible after confirming the password of the terminal previously input by the original user of the terminal.

As described above, according to the present invention, when a user of a mobile wireless terminal loses a terminal, a person who has acquired the terminal is restricted from using the mobile wireless terminal arbitrarily, and incoming and outgoing calls are possible, thereby allowing the lost terminal to be more. There is an advantage that is easy to find.
