Hereinafter, a preferred embodiment of a registered text message service processing method and system for an outbound roaming terminal according to the present invention will be described in detail with reference to the drawings.

1 is a mobile communication network structure for explaining a registered text service according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication network according to an embodiment of the present invention may largely include a home network 160 and a roaming network 170.

Here, the home network 160 and the roaming network 170 may transmit and receive data and control signals through the IP communication network 130 and the gateways 124 and 152 providing a connection interface with the external network.

The registered text service according to the present invention is a service for notifying the calling terminal whether the text message transmitted from the calling terminal is normally received by the called terminal and whether the called terminal user has read the received text message.

In particular, when the calling terminal 110 transmits a text message to the mobile terminal 140 outbound roaming through the home network 160, the registered text server 120 of the home network 160 is roaming network The registered text service providing method for an outbound roaming mobile terminal capable of transmitting to the calling terminal 110 through a predetermined text message whether the corresponding text message is normally transmitted to the called terminal 140 connected to the 170. To provide.

In the following description, a method of providing a registered text service for an outbound roaming mobile terminal will be described in detail with reference to FIG. 1.

Referring to FIG. 1, the home network 160 includes a base station 112, a base station controller 114, an exchange 116, a text message service server 118, a registered text server 120, and a home location register. And a home location register 122 and a gateway 124.

The base station 112 according to the present embodiment transmits a text message received from the calling terminal 110 through the base station controller 114 and the exchange 116 to receive a text message, wherein the text message includes a registered text service request message. It may perform a function of forwarding to the server 118.

The exchange 116 receives the text message received from the text message server 118, where the text message includes the received notification message and the read notification message generated by the registered text server 120, and the base station controller 114 and It may transmit to the calling terminal 110 through the base station 112.

In addition, when the terminating terminal 140 roams outbound, the exchange 116 may perform a function of transmitting a text message received through the gateway 124 to the roaming network 170.

The text message server 118 processes the short message and the long message, and when the reception number of the text message received from the mobile terminal is configured with a special number associated with the registered text service, the text message server 120 transmits the text message to the registered text server 120. Function can be performed.

Here, the special number associated with the registered text service may be configured in the form of a prefix or suffix of the called terminal phone number according to the type of the registered text service.

For example, when the registered text service type is a reception confirmation request, the reception number received from the mobile terminal may be composed of '## 4324 + subscriber' phone number 'which is a combination of a special number' ## 4323 'and a subscriber's phone number. .

In addition, when the registered text service type is a reception / read confirmation request, the reception number received from the mobile terminal may be composed of a special number '## 4324' and a '## 4324 + subscriber's phone number' which is a combination of the subscriber's phone number. have.

Here, the subscriber's telephone number is a mobile station integrated system digital network (MSISDN) for identifying a subscriber in GSM and WCDMA networks, a mobile identification number (MIN) and a mobile directory number (MDN), which are subscriber identification numbers in an IS-41C network. It may include.

In addition, the text message server 118 performs an authentication procedure for the mobile terminal through interworking with the home location register 122 according to the authentication request received from the registered text server 120, and controls the authentication result. Through the signal may be transmitted to the registered character server 120.

Here, the registered text server 120 through the authentication process described above whether or not to subscribe to a specific service for the mobile terminal-where the service includes a registered text service-information such as terminal type and capability (Capability) Can be obtained.

For example, when the called terminal is prohibited from sending a text message or the terminal is unable to process the text message, a reception and read confirmation service may not be provided.

Accordingly, the registered text server 120 may generate a notification message for not providing a predetermined service and transmit the message to the calling terminal.

In addition, when the called terminal is not subscribed to the registered text service, the registered text server 120 may generate a predetermined registered text service unavailable notification message and transmit it to the calling terminal.

The text message server 118 may check whether the text message transmitted through interworking with the exchange 116 is normally transmitted to the corresponding mobile terminal, and notify the registered text server 120 of the transmission result using the status report message. Can be.

In particular, when the text message server 118 receives a predetermined read confirmation message from the registered text server 120, the text message server 118 receives information from the home location register 122 about whether the mobile terminal to receive the read confirmation message is outbound roaming. Can be obtained.

The text message server 118 may transmit the outbound roaming of the called terminal to the registered text server 120 using a status report message.

The registered text service according to the present invention may largely include a reception confirmation service and a read confirmation service.

The acknowledgment service checks whether the text message transmitted from the mobile communication system to the called terminal is normally transmitted, and transmits the result of the text message to a predetermined acknowledgment message, where the acknowledgment message may be in the form of a text message. This is a service to send to the calling terminal. Therefore, the registered text server 120 does not need to receive a separate text message from the called terminal indicating that the text message has been normally received.

That is, in the case of the acknowledgment service, the data charge in the roaming network 170 for the outbound roaming called terminal is not added.

On the other hand, in the read confirmation service, when the registered text server 120 receives a predetermined read confirmation response message from the called terminal, the registered text server 120 transmits a predetermined read confirmation notification message to the calling terminal. It is a text service. Here, the read confirmation response message and the read confirmation notification message may be in the form of a text message,

If the called terminal is not an outbound roaming terminal, the registered text server 120 should not add a data charge for the read acknowledgment message received from the called terminal.

However, if the called terminal is an outbound roaming mobile terminal, since the roaming network 170 recognizes the read acknowledgment message received from the called terminal 140 as a general text message, the data on the received read acknowledgment message is received. Fees can be added.

This may be recognized as an unfair fee for the called terminal user, and may be an obstacle in activating the registered text service.

In general, the roaming network 170 may not be provided with a registered text service. Accordingly, the response message to the read acknowledgment message transmitted from the home network 160 by the text message received from the called terminal 140 may be provided. It is not known whether or not.

Accordingly, the roaming network 170 processes the read acknowledgment message received from the called terminal 140 as a general text message, and an unnecessary data charge for the called terminal 140 may be added.

In order to solve the above problems, the registered text service according to the present invention is characterized in that only the acknowledgment service is provided for the outbound roaming mobile terminal even if the calling terminal requests the read acknowledgment service.

When the destination terminal 140 roams outbound, the registered text server 120 according to the present invention converts the read confirmation message into a general text message and transmits it to the roaming network 170.

The exchange 146 of the roaming network 170 transmits the transmission result of the general text message to the exchange 116 of the home network 160, and the exchange 116 of the home network 160 transmits the general text message. The result is passed to the text message server 118.

When the text message server 118 transmits the transmission result for the general text message previously transmitted to the registered text server 120 using the status report message, the registered text server 120 indicates whether the text message is normally received. A reception notification message including a predetermined guide string may be transmitted to the calling terminal 110.

As a result, the present invention not only checks whether the text message transmitted from the calling terminal 110 is normally received by the called terminal 140 through the receiving notification message, but is unnecessary for the outbound roaming called terminal 140. Data charges can be prevented from being added.

In the above description, when the calling terminal requests a read confirmation registered text service to an outbound roaming called terminal, only the method of providing an acknowledgment service in the registered text server 120 is described, but in another embodiment of the present invention According to the present invention, it should be noted that even when the called terminal is outbound roaming, the read terminal may provide the read confirmation service even if the receiving terminal allows the calling terminal to provide the read confirmation service.

For example, the mobile terminal user may register with the mobile communication system whether a read confirmation service is provided according to outbound roaming through a predetermined user interface through a wired / wireless communication network.

Here, the outbound roaming read confirmation service setting information may be stored in a home location register located in a home network.

Therefore, when the registered text server 120 receives the registered text service request from the calling terminal, the registered text server 120 obtains outbound roaming read confirmation service setting information corresponding to the called terminal from the home location register, and according to the obtained information, the registered text service. Can provide services.

Although FIG. 1 illustrates that the registered text server 120 and the text message server 118 are configured as separate devices, the registered text server 120 and the text message server according to another embodiment of the present invention. It should be noted that 118 may consist of a single device.

For example, the function of the registered text server 120 described above may be configured as any one of a module, a process, and an agent in the text message server 118.

In the following description, when the text message server 118 and the registered text server 120 are configured as separate devices, a method and system for providing a registered text service to an outbound roaming mobile terminal will be described in detail. .

Referring to FIG. 2, the registered text server 120 receives a registered text service request message transmitted from the calling terminal 110 from the text message server 118 (S210).

Here, the text message server 118 transmits the received text message to the registered text server 120 when the received number included in the text message received from the calling terminal 110 is configured with a special number related to the registered text service. Be careful.

In the following description, a text message consisting of a special number related to a registered text service will be referred to as a registered text message.

When the destination terminal corresponding to the subscriber's telephone number included in the received number is outbound roaming, the registered text server 120 converts the received registered text message into a general text message (S220).

The registered text server 120 transmits the general text message converted in step 220 to the called terminal 140 connected to the roaming network 170 (S230).

When the registered text server 120 receives from the text message server 118 a status report message (Status Report Message) including information on whether the transmission is successful for the general text message transmitted in step 230 (S240). In operation S250, a predetermined reception notification message is transmitted to the calling terminal 110 according to the received status report message.

In particular, in step 220, when the text message server 118 receives the read confirmation message received from the registered text server 120, the information on whether or not outbound roaming of the subscriber's telephone number included in the received number Can be obtained from the home location register (122).

The obtained information about whether the called terminal roams may be transmitted to the registered text server 120 using a status report message.

3 illustrates a procedure of receiving a registered text service in a calling terminal according to an embodiment of the present invention.

However, in the present embodiment, only the case where the calling terminal 110 transmits the read confirmation request message to the outbound roaming called terminal through the home network 160 will be described.

In this case, the calling terminal 110 may be provided with a reception confirmation service instead of a read confirmation service.

Referring to FIG. 3, the calling terminal 110 may set a registered text service type according to a user input signal (S310).

Here, the calling terminal user may select a registered text service type by using a predetermined registered text service menu.

According to another embodiment of the present invention, it should be noted that the calling terminal user may directly input a special number corresponding to the registered text service type.

When the originating terminal 110 receives the text message service request signal through a predetermined user interface, the called terminal 110 is selected from a registered text service number corresponding to the set registered text service type and a phone book directly input by the user or stored in advance. Received number can be configured using the subscriber telephone number corresponding to (S320).

When the calling terminal 110 receives a text string to be transmitted through a predetermined text message input window (S330), the calling terminal 110 may transmit a text message including the input text string and the received number to the connected base station (S340).

When the caller terminal 110 receives the reception notification message corresponding to the text message transmitted in step 340, the calling terminal 110 may display the notification text included in the reception notification message on a predetermined display unit (S350). Here, the reception notification message may be in the form of a text message.

According to another embodiment of the present invention, the registered text server 340 may convert the notification text into a voice, an image, and transmit. In this case, the received notification message may be configured as a multimedia message.

For example, when the roaming check indicator is set to 0x01, the text message server 450 performs a procedure for checking whether the outbound roaming for the called terminal is performed. If the roaming check indicator is set to 0x00, the outgoing message for the called terminal is out. The procedure for checking whether or not bound roaming may not be performed.

When the text message server 450 receives the read confirmation message from the registered text server 460 (S410), it determines whether the destination terminal is outbound roaming (S412).

As a result of the determination, when the called terminal is roamed outbound, the text message server 450 registers a status report message including predetermined identification information indicating that the called terminal cannot roam outbound to provide a read confirmation service. In operation 414, the process transmits to step 460.

When the registered text server 460 determines that it is impossible to provide a read confirmation service through the received status report message, the registered text server 460 may convert the read confirmation message into a general text message (S416).

In this case, the registered text server 460 may set the roaming confirmation indicator of the general text message converted in step 416 to 0x00 (not checking whether the outbound roaming of the called terminal is checked).

When the text message server 450 receives the general text message converted in step 416 from the registered text server 460 (S418), the receiving terminal 420 receives the received general text message through the roaming network 170. It transmits to (S420).

When the text message server 450 obtains the transmission result for the general text message transmitted in step 420, the text message server 450 includes the obtained transmission result, where the transmission result is assumed to be successful in the transmission of the general text message. The report message is transmitted to the registered text server 460 (S422).

The registered text server 460 generates data charging information for the transmitted general text message and transmits the data to the charging server 430 (S424). The registered text server 460 generates a received notification message including a predetermined notification phrase. Then, the text message server 450 is transmitted (S450).

The text message server 450 transmits the received reception notification message to the calling terminal 410 through the home network 160 (S428), and then transmits a status report message including the transmission result to the registered text server 460. (S430).

When the registration text server 460 succeeds in transmitting the reception notification message, the registered text server 460 calculates an information fee and transmits the calculated information fee information to the billing server 430 (S432).

According to another embodiment of the present invention, it should be noted that a billing server for processing data billing information and a billing server for processing information usage billing information may be configured as separate devices.

When the registered text server 460 according to the present invention receives a status report message indicating that the authentication fails in step 406 or the transmission of the general text message in step 422, a predetermined service unavailable notification message is sent. It may transmit to the calling terminal 410. Here, the service unavailable notification message may be transmitted in the form of a text message.
