The present invention relates to a short message service (SMS), and more particularly to a method and apparatus for SMS-based long message service.

With the development of the mobile communication market, the term SMS (Short Message Service) has become widely known. The SMS is a text service that allows mobile phone users to send and receive short sentences of about 40 characters without additional equipment, and is also referred to as a short message service. As the spread of mobile phones spreads rapidly, the population of text service users is increasing rapidly, and unlike e-mail, the contents can be delivered almost simultaneously with the time of shipment. It is hardened. The SMS is basically provided with a function of transmitting a reply number and a message between terminals, not only know weather forecasts, news, stock information, etc., but also allows customers to directly search for various information and select only necessary information. In addition, it is possible to send and receive e-mails through the Internet and PC communications, and to provide various information retrieval services necessary for daily life.

In addition, the SMS has a protocol in a wired network such as a PSTN. 1 illustrates a message transmission and reception process in a typical SMS system. In FIG. 1, the SMSC 150 is a Short Message Service Center that receives an SMS from a sender and sends contents to a receiver. In addition, SMTE (Short Message Terminal Equipment, 100) is a message receiving equipment can be generally speaking telephone, mobile phone and the like.

The SMS service procedure consists of the following processes. When the SMSC 150 sends the Caller ID to the SMTE 100, the SMTE 100 knows that the CallerID is an SMS. When the SMTE 100 recognizes that it is an SMS, it wakes up a task capable of receiving an SMS according to a predetermined protocol, establishes a line connection with the SMSC, and then sends message data to be sent. When the message transmission is completed, the connection with the SMSC 150 is released.

However, the Short Message Service (SMS) is a service based on a short text. Therefore, only short sentences with limited data size can be transmitted and received. If the user intends to send a long sentence, protocols and equipment supporting the long sentence should be provided. Currently, to support SMS, long sentences are sent in SMS format. And the receiving side receives it like this.

Therefore, it is inconvenient to open a message from the back because of the trouble of having to open a message one by one even if the same content is used and a message buffer that is stacked like a stack.

The technical problem to be achieved by the present invention is an SMS-based long message service method that can be shown to the user at the receiving side even if the length of the message sent by the user in the use of the SMS service is longer than the message that is restricted by the protocol. And to provide an apparatus.

SMS-based long message service method according to the present invention for achieving the technical problem, (a) when receiving a short message packet, detecting the sender ID by analyzing the short message packet; (b) determining whether to connect the received short message with a short message immediately following; (c) if it is determined that the short message is to be connected, generating a predetermined buffer and storing the received short message in the buffer; And (d) if the short message packet is not received for a predetermined time, outputting the short message stored in the buffer as a long message.

In step (a), when the short message packet is received, the short message packet is analyzed to detect a sender ID and time information of the short message packet, and step (b) is performed by the sender of the packet and immediately before the packet. If the sender ID is the same and the time interval between the time of the packet and the time of the immediately preceding packet is within a predetermined time, it is preferable to determine that the short message is connected. The buffer generation in step (c) is preferably performed by extracting a data length (UDL) value from the short message packet and changing the size of the buffer according to the data length value.

SMS-based long message service device according to the present invention for achieving the technical problem, SMS receiving unit for receiving a short message packet; A packet analyzer configured to detect the sender ID by analyzing the received short message packet; A message connection determination unit determining whether to connect the received short message with a short message immediately following the short message; A message storage unit for generating a predetermined buffer and storing the received short message in the buffer when determining that the short message is connected; If the short message is not received for a predetermined time, it characterized in that it comprises a long message output unit for outputting the short message stored in the buffer as a long message.

The packet analyzing unit analyzes the received short message packet to detect sender ID and time information of the short message packet, and the message connection determining unit is the sender ID of the detected packet and the sender ID of the immediately preceding packet and the packet is identical. If the time interval between the time of and the time of the immediately preceding packet is within a predetermined time, it is preferable to determine that the short message is connected.

Hereinafter, an SMS-based palm message service method and apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing the configuration of the SMS-based long message service device according to the present invention, the SMS receiving unit 200, packet analysis unit 210, message connection determination unit 220, message storage unit 230 And a long message output unit 240.

The SMS receiver 200 receives a short message packet. At this time, check the number of the message service center (SMSC nunber) and confirm that it is SMS to receive a short message. The packet analyzer 210 detects the sender ID by analyzing the received short message packet. In addition, it is preferable to detect the transmission time or generation time of the short message packet, or check the reception time of the short message packet.

The message connection determination unit 220 determines whether to connect the received short message with a short message immediately following. At this time, if the caller ID of the detected packet and the sender ID of the immediately preceding packet are the same and the time interval between the time of the packet and the time of the immediately preceding packet is within a predetermined time, the short message is determined to be connected. It is preferable to. When determining that the message storage unit 230 connects the short message, the message storage unit 230 generates a predetermined buffer and stores the received short message in the buffer.

If the short message output unit 240 does not receive the short message for a predetermined time, the short message output unit 240 outputs the short message stored in the buffer as a long message.

Meanwhile, FIG. 3 is a flowchart illustrating an SMS-based palm print message service method according to the present invention. Referring to FIG. 3, an operation of the SMS-based palm print message service device according to the present invention will be described.

First, the receiving side, for example, the SMTE in FIG. 1 confirms that the SMSC is a number and then wakes up a task capable of receiving the SMS (step 300). Upon receiving the SMS, the packet analyzer 210 receives the SMS. ) Analyzes the SMS packet and checks the caller ID and time (step 310). Then, the message connection determination unit 220 determines whether to connect the received short message (step 320). Varies. For example, if the sender ID of the packet is identical to the sender ID of the immediately preceding packet, and if the sender ID is the same, the time interval between the time of the short message packet and the time of the immediately preceding short message packet is within a predetermined time. In this case, the short messages are recognized as being continuous and determined to be connected to each other. You can also decide whether the user will connect short messages through the user interface.

After the short message connection decision is made, a buffer is generated and the received short message is stored in the buffer (step 330). The buffer generation may be performed uniformly with a predetermined size, but the short message packet may be used for more efficient memory use. It is preferable to extract the data length (UDL) value from and to generate the buffer by varying the size of the buffer according to the data length value.

Then, if the short message packet is not received for a predetermined time (step 340), it is determined that there are no short messages connected anymore, and the short message stored in the buffer is output as a long message (step 350). It can also be printed in letter form.

The present invention can be embodied as code that can be read by a computer (including all devices having an information processing function) in a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like.
