Description

Method for providing message service in mobile communication network and system thereof

The present invention relates to a method and a system for providing a message service in a mobile communication network. More particularly, the present invention relates to a method and a system for providing a message service through an authentication procedure for security in a mobile communication network.

The message service provided by the mobile communication network is a service that allows the mobile subscribers to exchange contents without any additional equipment and communicate the contents almost simultaneously with the time of dispatch. The number of users of the message service is continuously increasing, and the scope of use of the message service is continuously expanded to electronic payments and electronic commerce.

Conventionally, when a security setting for a specific message is required, the access of the message is restricted through an authentication procedure. In other words, the authentication procedure is performed once the message is received by the mobile communication terminal itself.

For example, by setting a lock function on the mobile communication terminal itself, it is possible to read the received message after entering the password. In this case, since every time a user wants to read all the passwords, the user has to enter a password.

Alternatively, by setting an authentication number on the message itself, a valid authentication number must be entered so that the received message can be viewed.

However, such a method of performing authentication in the mobile communication terminal has already received a message in the mobile communication terminal itself, so if the mobile communication terminal is lost, even if the authentication number is set, hacking the mobile communication terminal itself. There is a risk that personal information can be leaked because the messages can be viewed through the method.

Accordingly, an object of the present invention is to provide a method and system for providing a message service in a mobile communication network to receive a message after an authentication procedure.

Message service providing method according to a feature of the present invention in order to achieve the above problems,

A method of providing a message service in a mobile communication network, the method comprising: (a) requesting a password input from a destination terminal when the originating terminal sends a message; And (b) if the password received from the called terminal matches the password preset by the called subscriber, transmitting a message sent by the calling terminal to the called terminal.

In addition, the message service providing system according to another aspect of the present invention,

A message service providing system for providing a message service in a mobile communication network, comprising: a message transmitting / receiving unit which transmits a message transmitted and received between a calling terminal and a called terminal; And requesting a password input from the called terminal when the calling terminal sends a message in association with the message transmitting / receiving unit, and when the password received from the called terminal matches a password previously set by the called subscriber. It includes an authentication unit for allowing the transmission of the sent message.

According to the present invention, since the incoming message is controlled through password authentication, a password for releasing the lock of the terminal every time a user reads all the messages regardless of whether or not the security message after setting the lock function on the terminal itself for the security of the received message. Eliminate the inconvenience of having to enter.

In addition, by setting the calling party's incoming number without password authentication, the incoming subscriber's message is sent through password authentication for messages sent to other outgoing numbers. Allows you to select That is, even if a password is required to be entered, incoming calls can be blocked at the source by not inputting or incorrectly inputting.

In addition, messages that require security cannot be received without entering a password, so if a mobile phone is lost or a third party other than the subscriber obtains the mobile phone, important messages are exposed to prevent personal information from being leaked. Further increase.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

In addition, the term "… unit" described in the specification means a unit for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software.

Now, a method and system for providing a message service in a mobile communication network according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a network for providing a message service in a mobile communication network according to an embodiment of the present invention.

According to FIG. 1, the calling terminal 100 and the called terminal 200 are mobile communication terminals connected to the wireless access network 300 to receive a message service provided by the mobile communication network.

Here, the message service means a service for exchanging text or various types of data between the calling terminal 100 and the called terminal 200 through a message. For example, there is a short message service (SMS), a long message service (LMS), and a multimedia message service (MMS).

The wireless access network 300 is wirelessly connected to the calling terminal 100 and the called terminal 200 to transmit and receive a radio signal, and connects the calling terminal 100 and the called terminal 200 to the message service center 400. Although not shown in the figure, the radio access network 300 includes a base station and a base station controller. The base station is a network termination device that is directly coupled to the calling terminal 100 and the called terminal 200 through a wireless channel by performing baseband signal processing, wired and wireless conversion, and transmission and reception of a wireless signal. The base station controller manages and controls the base station and performs traffic control and mobility management related to call processing.

The message service providing system includes a message service center 400 that controls message transmission and reception, and an authentication server 500 that performs authentication for message reception of the called terminal 200.

Here, the message service providing system is composed of a message service center 400 and an authentication server 500, which perform their respective functions in terms of distinguishing separate physical devices. Or, if the message service providing system is implemented to perform each function in the same device, it includes a functionally separated message transceiver and authentication unit.

In the embodiment of the present invention, a message service center 400 and an authentication server 500 implemented as separate physical devices will be described.

The message service center (or message transmitting / receiving unit) 400 is responsible for transmitting and receiving messages, receiving the message sent by the calling terminal 100 and transmitting the received message to the called terminal 200. At this time, the message service center 400 transmits the message sent by the calling terminal 100 to the called terminal 200 when the authentication server 500 allows the sending of the message sent by the calling terminal 100.

At this time, prior to transmitting the message to the destination terminal 200, the message service center 400 in the form of a short message requesting a message sender guidance and password input to the destination terminal 200 at the request of the authentication server 500 Send a notification message.

The authentication server (or authentication unit) 500 performs authentication for the originating terminal 100 to transmit a message to the called terminal 200 in association with the message service center 400. That is, when a message is received from the calling terminal 100, the receiver 200 requests a password input. When the password received from the called terminal 200 matches the password set by the called subscriber in advance, the call terminal 100 transmits the message sent by the calling terminal 100.

2 is a block diagram showing a detailed configuration of an authentication server according to an embodiment of the present invention.

According to FIG. 2, the authentication server 500 includes a registration unit 520, a security number list DB 540, and an authentication unit 560.

The registration unit 520 is responsible for setting a password for message reception of the called terminal 200. The registration unit 520 is implemented in the form of a web server and provides a user interface (UI, User Interface) so that the called subscriber can specify a calling number to which a password and password authentication for receiving a message are applied through a wired or wireless Internet network.

The security number list DB 540 stores a security number list including a calling number to which a password set by the called subscriber and password authentication are applied through the registration unit 520.

The authentication unit 560 works in conjunction with the message service center 400, when the originating terminal 100 sends a message, the password set by the called party in advance stored in the security number list DB 540 to the called terminal 200 Ask for input. Here, the authenticator 560 may request the message service center 400 to transmit a notification message in the form of a short message requesting a message sender guide and a password input.

The authentication unit 560 allows transmission of the message to the destination terminal 200 when the password received from the destination terminal 200 matches the password stored in the security number list DB 540. If it does not match, the transmission of the message to the called terminal 200 is blocked.

In this case, when the passwords do not match with each other, the authentication unit 560 repeatedly requests the incoming terminal 200 to re-enter the password for a preset number of times. If the passwords still do not match through the re-request procedure, the message transmission to the called terminal 200 is suspended, and the called terminal 200 requests a password reset.

The authentication unit 560 establishes, in association with the registration unit 520, a security number list DB 540 to which the password and password authentication set by the called subscriber are applied through the registration unit 520.

At this time, the authentication unit 560 sets a first password for receiving a message sent to a specific caller number designated by the called subscriber according to an embodiment. That is, the first password is set in order for the incoming call to be sent to a specific caller number through password authentication. This has the same effect as setting a lock and password for certain messages that require security.

Also, according to another exemplary embodiment, the authentication unit 560 sets a second password for incoming authentication for a message originating from a calling number other than a specific calling number allowed by the called party. That is, the receiving subscriber sets the calling number to be called without password authentication, and sets the second password so that the incoming call is made through the password authentication for the message sent to the other calling number. In this way, the called party can have the effect of blocking the incoming call itself for the message sent to the calling number that does not allow the incoming call in advance. That is, because the password authentication is required before the incoming call, if you enter the wrong password or do not enter the password will not be received, it will be able to fundamentally block the reception of messages that do not want to receive, such as spam characters.

3 is an example of a password request screen for receiving a message according to an embodiment of the present invention.

3 shows a notification message in the form of a short message received from a message service center (400 in FIGS. 1 and 2) according to a request of the authentication server (500 in FIGS. 1 and 2). This notification message consists of a caller ID and a password input field.

When the called subscriber inputs a password through the key input unit of the called terminal 200, the called subscriber is transferred to the authentication server 500 via the message service center 400.

Now, a method of providing a message service in a mobile communication network will be described based on the above-described configuration.

4 is a flowchart illustrating a method of providing a message service in a mobile communication network according to a first embodiment of the present invention. That is, it shows a message service providing method through the connection between the components (100, 200, 400, 500) of FIG.

According to FIG. 4, the authentication unit (560 of FIG. 2) of the authentication server (500 of FIGS. 1 and 2) receives a caller number designated by a called subscriber and password authentication through a registration unit (520 of FIG. 2). A security number list is constructed and stored in the security number list DB 540 (S101).

Thereafter, when the calling terminal (100 of FIG. 1) sends a message (S103), it is delivered to the message service center (400 of FIG. 1).

The message service center 400 uses the home location register (not shown in the drawings) to determine the location of the called terminal (200 in FIG. 1) and the called terminal subscriber (ie, called subscriber) through password authentication according to an embodiment of the present invention. Check whether or not the authentication service subscriber to the message (S105).

If it is determined in step S109 that the case is not the authentication service subscriber, the message service center 400 transmits the message received in step S103 to the destination terminal 200 (S107).

If it is determined in step S109 that the authentication service subscriber, the message service center 400 requests authentication to the authentication server 500 (S109). In this case, the call history, that is, the caller ID and the caller ID of the message received through the step S103 is provided.

The authentication unit 560 determines whether the calling number is a calling number that requires password authentication (S111). In this case, the authenticator 560 determines whether the calling number is a specific calling number to which the first password designated by the called subscriber is applied according to an exemplary embodiment. That is, it corresponds to a case where a password is set for incoming call through password authentication for a specific caller ID.

According to another embodiment, the authenticator 560 determines whether the calling number is a calling number other than the specific calling number allowed by the called party. At this time, the second password is set for the calling numbers other than the specific calling number allowed by the called subscriber. Therefore, for a caller ID other than the caller ID allowed by the called party, the password is set in order to receive the call through password authentication.

If it is determined in step S111 that the authentication unit is not the calling number that requires password authentication, the message service center 400 transmits an authentication response with the result information 'no authentication processing' as result information (S113). That is, the first password is not the set calling number or the calling number is allowed to be received without password authentication to which the second password is not applied.

Then the message service center 400 transmits the message received in step S103 to the called terminal 200 (S115).

On the other hand, the authentication unit 560, as a result of the determination in step S111, if the caller ID is required for the password authentication, the message service center 400 transmits the authentication response containing the "notification message sending request" as the result information (S117). That is, it corresponds to a case where the first password is a set calling number or a calling number requiring password authentication for an incoming call to which the second password is applied.

Then, the message service center 400 sends an authentication message requesting a password input to the called terminal 200 (S119). In this case, the notification message may be configured in the form of a short message including a message sender (including a calling number) and a password input field.

When the called terminal 200 transmits the password inputted by the called subscriber (S121) to the message service center 400 (S123), the message service center 400 transmits the password to the authenticator 560 (S125).

The authentication unit 560 determines whether the password received in step S125 matches the password previously set by the called subscriber in step S101 (S127).

If it is determined in step S127 that the passwords do not match, the authentication unit 560 transmits the authentication completion to the message service center 400 by including the 'transmission not allowed' as the result information (S129).

The message service center 400 informs the destination terminal 200 that transmission is impossible due to a password mismatch (S131) and discards the message (S133).

If it is determined in step S127 that the passwords match, the authentication unit 560 transmits the completion of the authentication to the message service center 400 by including the 'transmission allowed' as the result information (S135).

Then, the message service center transmits the message received in step S103 to the called terminal 200 (S137).

5 is a flowchart illustrating a method of providing a message service in a mobile communication network according to a second embodiment of the present invention. In particular, in Figure 4 is an embodiment detailing the procedure after step S127.

According to FIG. 5, the authentication unit (560 of FIG. 2) of the authentication server (500 of FIGS. 1 and 2) requests the receiver terminal (200 of FIG. 1) to input a password and receives the received password. If there is a mismatch with the password set in advance (S201), it requests the message service center (400 of FIG. 1) to resend the notification message requesting the password input (S203).

The authenticator 560 counts the number of re-requests in step S203 (S205).

When the password is received from the called terminal 200 (S207), the authentication unit 560 determines whether the received password matches the password set in advance by the called subscriber (S209).

At this time, if there is a match, the authentication unit 560 requests the message service center 400 to transmit a message to the called terminal 200 (S211).

However, if it does not match, the authentication unit 560 determines whether the number of re-requests counted in step S205 exceeds the preset number (S213).

If it is determined in step S213 that the preset number of times is not exceeded, the authentication unit 560 returns to step S203 and repeats the subsequent steps.

If it is determined in step S213 that the preset number of times is exceeded, the message transmission to the called terminal 200 is suspended (S215) and the password is requested to the called terminal 200 (S217).

As such, when only a predetermined number of password input requests are required and password authentication fails, the third party attempts to view the message such as when the destination terminal 200 is lost by suspending the message transmission and requesting a password reset. The incoming message itself can be blocked so that the message cannot be viewed.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
