1 is a block diagram illustrating an overall configuration of a short message service system according to an embodiment of the present invention, and FIG. 6 is a conceptual diagram illustrating a short message transmission process in a short message system according to an embodiment of the present invention. A short message service system and a short message service method according to an embodiment of the present invention will be described with reference to FIGS. 1 and 6 as follows.

Short message service system according to an embodiment of the present invention, as shown in Figure 1, the user terminal 110, SMS server 130, message server 140, P2P server 150, a plurality of digital broadcast receiver ( The digital TVs 165 and 172 are physically connected to the 160 and 170 and the digital broadcast receivers 160 and 170 so that the command processing results of the digital broadcast receivers 160 and 170 are output in a visible form.

The user terminal 110 is a device capable of transmitting and receiving a short message (hereinafter, referred to as a short message) to the digital broadcast receiver 160 through a mobile communication network. For example, a mobile phone or a PDA may be used. A user may transmit a message to the digital broadcast receiver 160 using a user terminal 110 such as a mobile phone. When the message is transmitted to the digital broadcast receiver 160, a message server to which the corresponding digital broadcast receiver 160 belongs. The short message is transmitted using the representative phone number of 140.

Here, the representative phone number of the message server 140 means a phone number capable of distinguishing where the message server 140 and the P2P server 150 connected with the corresponding digital broadcast receiver 160 are located. Different representative phone numbers can be assigned. For example, when an apartment named 'Samsung' is composed of one, two, and three apartments, each complex includes a message server 140 for managing messages in each complex, and each message server ( 140, a representative telephone number can be assigned as shown in Table 1.

Representative phone number Message server 140 IP Name of message server 140 011-123-1234 1.1.1.1 Samsung Apartment Complex 1 016-666-6666 1.1.1.2 Samsung Apartment Complex 2 019-999-9999 1.1.1.3 Samsung Apartment Complex 3

When a representative telephone number is assigned to the message server 140 existing in each complex as shown in Table 1, the user writes a message through the user terminal 110, and then the representative telephone number example of the corresponding message server 140. For example, by entering 011-123-1234, a message can be transmitted. In this case, as illustrated in FIG. 2, the user terminal 110 transmits a message 200 in a packet form including sender information, receiver information, and a message. For example, if a user writes a message 'hello' using a mobile phone having a telephone number of 011-333-3333, and then enters 011-123-1234 as a receiver number, the message packet 200 shown in FIG. In the sender information area 210, the receiver information area 220, and the message area 230, a message packet ('011-333-3333', '011-123-1234' and 'hello') is recorded. 200 is generated and transmitted through the mobile communication network.

The base station (BTS) 120 or the base station controller (BSC) 125 functions as a relay for transmitting the message packet 200 transmitted from the user terminal 110 to the SMS server 130. In the case of the base station 120, the control of the incoming and outgoing of the mobile communication terminal in the area (Cell) managed by one base station and the radio channel in the base station, and the base station controller 125 manages eight or more base stations Manage.

Meanwhile, the SMS server 130 receives the message packet 200 transmitted from the user terminal 110 through a mobile communication network, for example, a CDMA mobile communication network (S610). The received message packet 200 is processed and converted according to a predefined format. That is, the first message packet 300 is generated (S614).

The format of the first message packet 300 generated by the SMS server 130 may include the sender information area 310, the receiver information area 320, and the message area 330 as shown in FIG. 3. Can be defined

In the sender information area 310 of the first message packet 300, information about a message sender is recorded. For example, if the sender information is '011-333-3333' as a result of processing the received message packet 200, the SMS server 130 records '011-333-3333' in the sender information area 310. Generate the first message packet 300.

In the receiver information area 320 of the first message packet 300, identification information of the message server 140 to receive the message is recorded. For example, IP address information for the message server 140 is recorded. In more detail, as shown in Table 1, the SMS server 130 includes a representative telephone number assigned to each message server 140, an IP address for each message server 140, and each message server. A message server information table including name information of 140 is stored, and after receiving the message packet 200, the SMS server 130 refers to the contents of the message server information table (S612), and receives a message. In operation S614, the first message packet 300 including the IP address of the server 140 is generated.

For example, if the information included in the receiver information area 220 is '011-123-1234' as a result of processing the received message packet 200, the SMS server 130 refers to the contents of the message server information table. Then, the IP address of the message server 140 whose representative telephone number is 011-123-1234 is retrieved. Then, the first message packet 300 having the retrieved IP address of the message server 140 as receiver information is generated. For example, in the above-described example, as illustrated in FIG. 3B, the SMS server 130 generates a first message packet 300 having '1.1.1.1' as receiver information (S614).

The same message information as the message included in the received message packet 200 is recorded in the message area 330 of the first message packet 300. For example, as a result of receiving and processing the message packet 200 transmitted from the user terminal 110, if the message area "Hello" is found in the message area 230, the SMS server 130 is the same message message The first message packet 300 recorded in the area 330 is generated (S614).

After generating the first message packet 300 in the above manner, the SMS server 130 transmits the first message packet 300 to the corresponding message server 140 (S616). At this time, the first message packet 300 is preferably transmitted to the corresponding message server 140 through the TCP connection.

Meanwhile, when the first message packet 300 transmitted from the SMS server 130 is received by the message server 140, the message server 140 processes the received first message packet 300 to send sender information 310. In step S620, an ID of the digital broadcasting receiver corresponding to FIG. In more detail, as shown in Table 2, each message server 140 includes ID information of the digital broadcast receiver 160 connected to the corresponding message server 140, and information of each digital broadcast receiver 160. A digital broadcast receiver information table including online status information and user terminal 110 information for each digital broadcast receiver 160 is stored. The message server 140 receives a digital message after the first message packet 300 is received. The ID of the digital broadcast receiver corresponding to the sender information 310 of the first message packet 300 is searched with reference to the contents of the broadcast receiver information table (S620).

User terminal 110 information Digital broadcast receiver ID Connection status 011-333-3333 123 On line 011-222-2222 456 On line 011-444-4444 789 Off line

For example, if the sender information included in the first message is 011-333-333 as a result of processing the first message packet 300, the message server 140 refers to the contents of the digital broadcast receiver information table, and 011. The ID of the digital broadcast receiver corresponding to the telephone number of -333-3333 is searched for (S620).

For example, if '123' is found as the ID of the digital broadcast receiver 160 corresponding to the sender information of the first message packet 300, the message server 140 receives the ID of the retrieved digital broadcast receiver as receiver information 420. Generate a second message packet 400 (S622).

In this case, the format of the second message packet 400 generated by the message server 140 is, as shown in FIG. 4, a sender information area 410, a receiver information area 420, a transmission status information area 430, and the like. It may be defined to include a message area 440.

The sender information area 410 of the second message packet 400 is where information about the message sender, that is, the user terminal 110 is recorded. For example, if the sender information is 011-333-3333 as a result of processing the first message packet 300, the message server 140 may include a second message packet including information 011-333-3333 in the sender information area. 400 is generated (S622).

In the receiver information area 420 of the second message packet 400, identification information of the digital broadcast receiver 160 to receive the message, for example, an ID of the digital broadcast receiver 160 to receive the message is recorded. In the above-mentioned example, the message server 140 generates a second message packet 400 having '123' as receiver information (S622).

Next, the transmission status information area 430 of the second message packet 400 is a portion in which the transmission status information of the message is recorded and may have a value of 'Success', 'Fail' or 'Null'. The second message packet 400 generated by the message server 140 is transmitted to the P2P server 150. When the second message packet 400 is transmitted to the P2P server 150, the second message packet 400 is transferred to the transmission status information 430. A second message packet 400 with a Null 'value is sent.

Thereafter, when the P2P server 150 successfully receives the second message packet 400 transmitted from the message server 140, the P2P server 150 transmits the message of the received second message packet 400. The information 430 is updated to 'Success' and returned to the message server 140 (S630). If the P2P server 150 fails to receive the second message packet 400, the P2P server 150 updates the message transmission status information 430 of the received second message packet 400 to 'Fail'. In step S630, the message server 140 returns to the message server 140.

The message server 140 checks the transmission status information 430 of the second message packet 400 returned from the P2P server 150, and when the transmission status information 430 is 'Fail', the second message packet It is determined that the transmission has failed, so that the same second message packet 400 (the transmission status value is 'Null') can be retransmitted (S629).

Meanwhile, the same message as that of the first message packet 300 is recorded in the message area 440 of the second message packet 400. For example, as in the aforementioned example, when the first message packet 300 includes the message information 'hello', the message server 140 displays the message 'hello' in the message area 440. The recorded second message packet 400 is generated (S622).

After generating the second message packet 400 in the above manner, the message server 140 checks the digital broadcast receiver information table and checks the network connection state of the corresponding digital broadcast receiver 160 (S624). That is, it is determined whether the corresponding digital broadcast receiver 160 is online or offline.

In more detail, as shown in Table 2, the storage unit 145 of the message server 140 stores a digital broadcast receiver information table including connection status information about the digital broadcast receiver 160. do. Here, the connection state information is updated according to the response signal transmitted from each digital broadcast receiver 160. More specifically, when the digital broadcast receiver 160 is online or offline, the digital broadcast receiver 160 generates a status information message accordingly and transmits it to the message server 140 and the P2P server 150. When the message server 140 receives the status information message from the digital broadcast receiver 160, the message server 140 updates the connection status information of the digital broadcast receiver information table according to the type of the received status information message.

On the other hand, if the receiving digital broadcast receiver, for example, as a result of confirming the connection state of the first digital broadcast receiver 160, the corresponding digital broadcast receiver 160 is offline (S624, No), the message server 140 2 the message packet 400 is stored in the message storage unit 145 (S626), so that it can be retransmitted later.

As a result, if the digital broadcast receiver 160 is online (S624, Yes), the message server 140 transmits the second message packet 400 to the P2P server 150 (S629). At this time, the second message packet 400 is preferably transmitted to the P2P server 150 through the TCP connection.

On the other hand, the P2P server 150 receives the second message packet 400 from the message server 140, and confirms the IP address of the receiving side (S631). In more detail, as shown in Table 3, the storage unit 155 of the P2P server 150 includes ID information and IP address information of the digital broadcast receiver and connection state information of each digital broadcast receiver. A digital broadcast receiver connection state information table (hereinafter, referred to as a connection state information table) is stored. The P2P server 150 generates a third message packet 500 including the IP address of the receiving digital broadcasting receiver according to the contents of the connection state information table (S632) and transmits the same to the digital broadcasting receiver 160. (S634).

ID of digital broadcast receiver IP address Connection status 123 1.1.2.1 On line 456 1.1.2.2 On line 789 1.1.2.3 Off line

At this time, the format format of the third message packet 500 generated by the P2P server 150 is, as shown in FIG. 5, the message identification information area 510, the message area 520, and the message reception status information area ( 530).

Here, the message identification information area 510 is a portion in which identification information about the corresponding message is recorded, and for example, may allocate an area having a size of 3 bytes. When the third message packet 500 is transmitted from the P2P server 150, the digital broadcast receiver 160 processes the received third message packet 500, and according to the processing result, the component in the digital broadcast receiver 160. To control. For example, when the first 3 bytes of the received third message packet 500, that is, the information of the message identification information area 510 is checked and information indicating that the message is received, a program capable of outputting a message To drive.

In addition, the third message packet 500 includes message reception status information. The value of the message reception status information region 530 may have values of 'Success', 'Fail', and 'Null'. When the third message packet 500 is transmitted from the P2P server 150 to the digital broadcast receiver 160, the third message packet 500 having the value of the message reception state information is 'Null' is transmitted.

Thereafter, when the digital broadcast receiver 160 successfully receives the third message packet 500 transmitted from the P2P server 150, the digital broadcast receiver 160 receives the message of the received third message packet 500. The reception status information is set to 'Success' and returned to the P2P server 150 (S640). The digital broadcast receiver 160 processes the received third message packet 500 so that the content of the message received through the digital TV 165 may be output (S650). If the third message packet 500 is not successfully received from the P2P server 150, the digital broadcast receiver 160 'Fail' the message reception state information of the received third message packet 500. Set to return to the P2P server 150 (S640).

Meanwhile, the P2P server 150 receives the third message packet 500 returned from the digital broadcast receiver 160, and then checks the message reception state information 530 of the received third message packet 500. It is determined whether the message transmission is successful (S636). As a result of the check, when the message reception status information is 'Fail', it is determined that the transmission of the third message packet 500 has failed, and the same third message packet 500 (the message reception status information value is 'Null') is retransmitted. It may be (S634).

Next, a message transmission method performed between digital broadcast receivers in a short message service system according to an embodiment of the present invention will be described.
