Description

System and Method for Selective SMS Termination Acceptance in Mobile Communication System

The present invention relates to a short message service system and method in a mobile communication system, and more particularly, to a system and method for blocking a short message that is not desired to be received.

The mobile communication system is a mobile communication service that is used by individuals and is used to carry voice and low-speed data communication regardless of time and place by using an ultra-compact, ultra-lightweight terminal that is portable. These mobile communication service subscribers can move freely and communicate anywhere, and are further provided with a function of receiving necessary information by text or voice. For example, wireless mobile communication service providers can send news information, weather information, sports information, stock information, exchange rate information, traffic information, etc. to subscribers of wireless mobile communication service by using short message service (SMS) that enables simple message transmission. Providing.

The short message service (SMS) refers to a two-way text service that can send and receive short messages regardless of the communication between mobile communication terminals. This service enables subscribers of wireless mobile communication services to send short messages of about 255 bytes to other mobile phone subscribers in Korean or English to receive messages via public telephone networks, data communication networks or the Internet.

With the recent increase in mobile communication service providers and wireless Internet service providers, services provided to mobile communication terminal users have been diversified for each service provider. Accordingly, short messages transmitted to terminal users for the promotion and advertisement of such services are diversified. The number of people is increasing.

However, in the conventional short message receiving method, since a short message related to promotion or advertisement of each service company is transmitted indiscriminately to a plurality of terminal users, the terminal user who cannot arbitrarily block the short message is unnecessary information to the user. There was an inconvenience to check and delete the contents of the short message received daily.

For example, in the case of a broadcast short message related to advertisement or company promotion provided by a specific business or a specific age group, it may be useful only to a few related terminal users and unnecessary short message for other terminal users. It only makes the user bother.

In addition, there is a problem in that the battery of the terminal is consumed due to the unnecessarily received short message, thereby reducing the terminal usage time due to battery waste.

The inconvenience that a mobile terminal user suffers from receiving a short message is not only a short message that includes such unnecessary information, but also a short message that includes a lewd language transmitted by a specific terminal user. It's happening all the time.

Even in this case, the terminal user does not want to receive the short message to be transmitted, but there is an inconvenience in that it is necessary to delete the short message after checking the received short message because the reception control means for the received short message is not provided.

In addition, there is a problem in that resources such as a mobile communication exchange and a base station are wasted in order to transmit an unnecessary short message as described above.

Accordingly, an object of the present invention for solving the above problems is to provide a system and method for preventing the receipt of a short message by an unsolicited originating subscriber.

Another object of the present invention for solving the above problems is to provide a system and method for preventing the mobile terminal from wasting energy when receiving unnecessary text messages.

Another object of the present invention for solving the above problems is to provide a system and method that can prevent the overhead and resource waste caused by unnecessary signal transmission.

According to an aspect of the present invention, there is provided a method for controlling selective reception of a short message in a system for providing a short message service, the method comprising: receiving caller address information allowing a short message to be received from a mobile terminal; And a second step of checking whether the address information of the sender requesting the short message transmission according to the short message transmission to the mobile terminal is the address information allowing the mobile terminal to receive the short message, and as a result of the checking of the second step, And if the sender's address information is not included in the address information registered by the specific mobile terminal, a third step of blocking the short message to the mobile terminal.

In the short message system for providing a short message service, the present invention provides a short message service, and receives caller address information allowing a short message from a mobile terminal, and generates / stores an address information list for each mobile terminal. And a home location register that provides address information of a specific mobile terminal according to whether the address information of the requested sender that has sent the short message to the specific mobile terminal is included in the address information list registered by the specific mobile terminal. And a short message center for requesting address information of the mobile terminal to the home location register according to the short message transmission and transmitting a short message to the obtained address information from the home location register.

Hereinafter, the detailed operation and structure of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that reference numerals and like elements among the drawings are denoted by the same reference numerals and symbols as much as possible even though they are shown in different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention proposes a system and method for registering a subscriber to allow a short message to be received at a home location register for each incoming subscriber and selectively authorizing a short message to be received.

First, the configuration of the short message service system according to the present invention as described above will be described with reference to FIG.

Referring to FIG. 1, the mobile terminal 101 receives a text message or a voice message from a user and transmits it to the base station 102, or receives a text message or a voice message from the base station 102 and outputs the text message or voice message for the user to confirm. Can be. In addition, the mobile terminal 101 receives a caller address information for receiving a short message from a user, and further transmits a text message allowable sender address information list to which the identification number of the mobile terminal is added to the base station 102. Include.

The base station 102 plays a role of controlling the incoming and outgoing of the mobile communication terminal in an area (Cell) managed by one base station, management of radio channels in its base station, and the like. In addition, the base station 102 transmits the text message allowable sender address information list received from the mobile terminal 101 to the exchange 104, and transmits a short message received from the exchange 104 to the mobile terminal 101. do.

The exchange 104 connects to the base station 102 and is responsible for call processing and relay functions for the mobile terminal.

The short message center (SMSC) 105 is a home based on a request to send a short message from the mobile terminal 101, the Internet 106, the public switched data network 107, or the information provider 108 via a wired / wireless network. Obtain the address information of the mobile terminal to which the short message is to be transmitted from the location register 103, and transmit the information to the mobile terminal through the corresponding exchange 104 including information such as a called party's telephone number and caller's telephone number information. do.

In addition, the short message center 105 transmits a short message address request message to a home location register 103 to obtain address information of the mobile terminal to which the short message is to be transmitted. An example is shown in FIG. 2.

Referring to FIG. 2, a mobile terminal identifier (MIN) is a unique ID of a 10-digit destination mobile terminal. Electronic Serial Number (ESN) is optionally added in 32 bits. The short message notification indicator (SMS_Notification Indicator) is a parameter that determines whether or not to notify the calling party when the called party can normally receive. SMS_TeleserviceIdentifier is a parameter indicating which service of the upper layer the message is used for. In particular, the SMS_OriginalOriginatingAddress 201 is a sender address information for determining whether a sender who has requested to send a short message is allowed to receive a short message from the mobile terminal, and is a parameter added by the present invention.

In addition, the short message center 105 receives a result message corresponding to the short message address request message from the home location register 103, and, according to the result message, the recipient's telephone number and the caller's telephone number information, etc., in the short message. The information is transmitted to the mobile terminal through the switch 104, or a short message transmission impossible message is generated and notified to the calling party.

The home location register (103) is a database storing a short message allowable sender address information list for each mobile terminal for receiving a short message from a mobile terminal, and a sender address requesting a short message transmission to the specific mobile terminal. It includes a function to check whether it is included in the address information list. Therefore, when the home location register 103 receives the short message address request message from the exchange 104, the home location register 103 transmits the short message request result message to the switch 104 according to the check result. 3 is shown.

Referring to FIG. 3, an electronic serial number (ESN) is a distinguishing number of a called party's mobile terminal. The short message address (SMS_Address) is an address of the short message terminating mobile terminal, and is a field added selectively only when the sender address is included in the address list registered by the terminating mobile terminal. SMS_Access Denied Reason (SMS_Access Denied Reason) is a field added when the short message is not transmitted to the mobile terminal, the rejection reason list according to the set value is shown in FIG.

Referring to FIG. 4, when the short message access rejection reason field is 8 bits, when the short message is rejected because the mobile terminal corresponding to the mobile terminal identifier included in the short message address request message cannot be found. Set the value to '1'. When the short message transmission is postponed due to power off of the mobile terminal, the value is set as '2'. If the address of the mobile terminal is unavailable, the value is designated as '3'. If the short message service ID is not valid, the value is designated as '4'. When the short message is not allowed by the terminating mobile terminal, the value is designated as '5'.

Then, the short message selective authorization method according to the present invention in the system configured as described above will be described with reference to FIG.

First, in response to a caller address information input request for receiving a text message from a user, the mobile terminal 101 receives a short message allowable caller number list input through a key input means of the mobile terminal, and transmits it to the base station 102. Send. Upon receiving the short message allowable calling party number list, the base station 102 transmits it to the home location register 103 through the switch 102.

The home location register 103 stores the received short message allowable calling party number list in the internal database for each mobile terminal corresponding thereto.

Subsequently, when a request for adding or deleting short message allowable caller number list information is requested from the same mobile terminal, a specific telephone number may be added or deleted to the short message allowable caller number list corresponding to the mobile terminal.

5 is a diagram illustrating the operation of the home location register 103 storing the short message allowable caller number list as described above.

Referring to FIG. 5, in step 500, the home location register 103 is requested from the short message center 105 to receive address information of a mobile terminal to which a short message is to be transmitted. At this time, the received message is as shown in FIG.

In step 510, the home location register 103 determines whether an optional short message incoming service is registered and activated in the short message terminating mobile terminal. As a result of the determination in step 510, if the selective short message incoming service is registered and activated for the called mobile terminal, the home location register 103 performs the short message request sender included in the message shown in FIG. By detecting the number, it is determined whether the detected caller number is included in the short message allowable caller number list of the corresponding terminal.

As a result of the determination in step 520, if the calling party number is included in the short message permitting caller number list of the terminal, the home location register 103 transmits the destination address information of the short message to the short message center 105 in step 530. do. The short message center 105 then transmits the short message to the mobile terminal via the exchange 104 and the base station 102.

On the contrary, when the determination result of step 520 indicates that the short message permitting caller number of the called terminal is not stored in the data base, the home location register 103 performs the short message request result message shown in FIG. 5 in step 540. The short message access denied reason field of the terminal is designated as a value '5' indicating that the short message access denied by the user is transmitted to the short message center 105.

The short message center 105 then transmits the rejection reason to the sender who requested the short message transmission.

As described above, the present invention can set the user to reject incoming or outgoing messages from a specific person or to receive incoming or outgoing messages from a specific person, thereby eliminating inconvenience caused by unnecessary calls or messages. have.

In addition, it is possible to prevent unsolicited short message reception by the called subscriber in the home location register, thereby preventing unnecessary occupancy of resources of the exchange and the base station on the called party.

In addition, there is an advantage that the mobile terminal can prevent energy waste when receiving unnecessary text messages.
