The terminal 104 is a terminal in which a function of processing a long-term transmission / reception service is implemented. The terminal 104 is equipped with a function of processing a long-term transmission / reception service in a mobile terminal (MS), thereby making a voice call function and at the same time. It can also be implemented to have a service function. The terminal 104 serves to provide or receive a full text to the external terminal 105.

The terminal 105 is connected to the terminal 104 to generate a full text to be transmitted to the terminal 104 or to receive the full text transmitted from the extended short message server 101 from the terminal 104.

The host 106 is connected to the extended short message server 101 to generate a long message to be transmitted to the terminal 104 or to receive a long message received from the terminal 104 from the extended short message server 101.

Inter Processor Communication (IPC) is a protocol for interprocessor communication within an exchange.

Next, the configuration and operation of a mobile communication network to which the present invention is applied are as follows.

The extended single-text server 101 is a server that transmits / receives the terminal 104 and the full-text, and is a single-service center (SMSC) 102 and a transmission control protocol / Internet protocol (TCP / IP: Transmission Control Protocol / Internet Protocol). The extended single message server 101 generates a full text message to be transmitted at the time of transmission or is connected to an external host 106 to receive a full text message to be transmitted from the host 106 to divide the long text message with a single information service center (partition information). 102 is transmitted to the host 106 after receiving or recovering the long text using the divided information received from the short text received from the short text service center 102.

Looking at the structure of the protocol to be implemented for each element in order to send / receive the full text between the extended single-text server 101 and the terminal 104 as follows.

Between the short-term extension server 101 and the short-term service center 102 using a short message peer to peer (SMPP) 202 based on the transmission control protocol / Internet protocol (TCP / IP) (203/204) Give and receive professional

The professional service center 102 converts an SMPP 202 message into an IS-637 (TIA / EIA Interim Standard: Short Message Service for Wideband Spread Spectrum Cellular System) teleservice message 206. Processes the function of interworking with the base station controller / mobile communication switch 103 via the signaling method (No. 7) interface.

The base station controller / mobile communication switch 103 uses the terminal through the IS-637 (211,212,213) and IS-95-A (TIA / EIA Interim Standard: Mobile Station-Base Station Compatibility for Dual-Mode Wideband Spread Spectrum Cellular System) interfaces. 104) send and receive monographs.

The data application layers 201 and 214 are implemented in the terminal 104 and the extended monograph server 101 which are the starting and ending points of the long message transmission / reception.

3 is a structural diagram of a data application layer according to the present invention.

The full text 301 to be transmitted in the data application layers 201 and 214 of FIG. 2 is divided to form user data fields of the teleservice layer 206 together with the split information 302 and 303. What constitutes the data application layers 201 and 214 is the terminal 104 of FIG. After the segmentation information 1 302 is generated according to the length and contents of the long text 301, the segmentation information 1 302 is divided and the segmentation information 2 303 is generated. The split length criteria depends on the channel to be transmitted. The user data field is composed of the divided full text 304, the split information 302, 303, and the user data overhead 305, thereby forming a single full text. The receiver recovers the long message 301 through the split information 302 and 303 of the short messages. In this case, the split information 302 and 303 may include the number, order, length of the long message, and a command field between the terminal and the extended short message server. The user data overhead 305 is composed of fields relating to the length of the divided telegraph and the method of encoding the divided telegram. The receiving side recovers the long text 301 through the divided short messages 304 and the short information split information 302,303. The method of restoring a long text into short texts is the reverse of the method of dividing a long text into short texts.

The long text length 401 indicates the length of the long text message to be transmitted, and the command field 402 indicates the type of command that the extended short text server 101 issues to the terminal 104 and the terminal 104 expands the short text message server 101. This field is used to report the command. The number of monograms 403 and the order 404 are the total number and order of the monograms, which are necessary data for combining the monograms.

If the extended terminal server 101 has commanded the terminal 104 to report the location every hour, the command field 402 indicates a command to report the location of the terminal 104 and reports every hour. The full text 301 is shown.

The location report of the terminal 104 to the extended short message server 101 for the command indicates that the location report is reported regardless of the terminal 105 in the command field 402 and the location information is displayed in the full text 301. .

5 is a flowchart illustrating a long field segmentation method according to the present invention.

In the case of a terminal call, a transmission channel is selected from a terminal 104 or a terminal 105 in which a full text is generated. In the case of a terminal call, a transmission channel is generated from a host 106 or an extended single-text server 101 in which a full text is generated. It is possible to choose. The present invention includes transport channel selection in the transmission of a long message into short messages according to a transmission channel. Until now, the monograph service determined the length of the monograph and automatically decided the transmission channel.

In case of a terminal call, an access channel or a traffic channel is used as a transport channel, and in case of a terminal call, a paging channel or a traffic channel is used as a transport channel. In the present invention, the length of the short messages is divided into the full length and the short length as the reference length of the selected channel. The reference length of the selected channel means the maximum length that the selected channel can transmit stably and repeatedly.

In the case of a terminal call, if the full text to be transmitted is input (500), the type of the transmission channel selected by the sender is determined (501). If the traffic channel is input, the length of the input text can be transmitted to an access channel (paging channel in case of a terminal call). If the long length is less than or equal to the reference length of the access channel, the input full length is padded with the reference length of the traffic channel (503), and then segment information is generated. (508).

On the other hand, if the length of the full length is greater than the reference length of the access channel, it is determined whether the length of the long length is less than or equal to the reference length of the traffic channel (504) and if the length of the long length is less than or equal to the reference length of the traffic channel, the split information is immediately generated without being divided. If the length of the full text is larger than the reference length of the traffic channel (508), the input long text is divided into the reference length of the traffic channel, and the last short text of the divided short messages is padded with the reference length of the traffic channel (505). The partition information is generated (508).

On the other hand, if the channel selected by the sender is an access channel (a paging channel if the terminal is called), it is determined whether the length of the telegraph is less than or equal to the reference length of the access channel (506). If the length of the full text is larger than the reference length of the access channel, the divided information is divided (507) after the input long text is divided into the reference length of the access channel (508).

6 and 7 are flow charts of messages between the extended single message server 101 and the terminal 104. The terminal incoming process and the terminal 104 transmit the long message to the terminal 104. ) Consists of a terminal calling process for transmitting the full text to the extended single-text server 101, the specific method is as follows.

6 is a flowchart of a terminal incoming process in the long message transmission method according to the present invention.

In the case of a terminal incoming, when the host 106 sends a long message request message Send_Msg to the extended single-text server 101 (601), the extended single-text server 101 has a full text and configures the data application layer. Done. That is, the given full text is divided into short messages, and the split information is generated to transmit the short texts in order. First, the extended single message server 101 transmits the first single message to the single message service center 102 through the single message transmission request message (submit_sm) (602). Upon receiving the short message request message, the short message service center 102 transmits the short message to the mobile communication switch 103 using the IS-41C Short Message Deliver Point to Point (SMDP) message (603). The exchange 103 transmits the short message to the base station controller / base station 103 using the short message transmission message SM_Send_Mag (604), and the base station controller / base station 103 transmits the data burst message (Data_Burst_Msg) of the IS-95A. In step 605, the full message is transmitted to the terminal 104 through a paging channel or a traffic channel. The terminal 104 transmits whether the terminal 104 receives the single-purpose service center 102 through the SMS Acknowlege Message of the IS-637 (606). The single professional service center 102 transmits a single professional delivery confirmation message (deliver_sm: delivery receipt) to the extended single professional server 101 (607).

Thereafter, the extended single message server 101 transmits the single message in order from the second single message to the last single message in this manner. The terminal 104 restores the received multiple short messages to the original long message using the split information, and then, if the long text to be transmitted to the terminal, the long text is transmitted through the long text transmission message Send_Msg. (608). When the terminal 104 receives the long message transmission message response (Send_Msg_Res) from the terminal 105 (609), the terminal 104 transmits a terminal originating short message (SMS Submit Message) to the terminal specialized service center 102 (610). The single-specialty service center 102 notifies whether the message is transmitted to the extended single-specialized server 101 through the single-specialized response message (611), and the extended single-specialized server 101 hosts the long-term transmission confirmation message Send_Msg_Ack. Forward to 106 (612).

7 is a flowchart of a terminal origination process in the long text transmission method according to the present invention.

In the case of a terminal call, when the terminal 105 transmits a long message request message Send_Msg to the terminal 104 (701), the terminal 104 configures a data application layer. That is, by dividing a given full text into a single message and generating split information, the first single message is loaded into a data burst message (Data_Burst_Msg) and transmitted to the base station controller / base station 103 through an access channel or a traffic channel (702). The base station controller / base station 103 transmits the single message to the mobile switching center 103 using the short message transmission message SM_Send_Msg (703), and the mobile switching center 103 uses the IS-41C SMDPP message to send the short message. The full text is transmitted to the monopoly service center 102 (704). The single professional service center 102 informs the terminal 104 whether the message is received through the SMS Acknowlege Message of the IS-637 (705), and expands the single message in the single expert response message (deliver_sm). It transmits to the single server 101 (706).

Thereafter, the terminal 104 transmits the single message in sequence from the second single message to the last single message in this manner. After receiving the last single message, the extended single message server 101 transmits the single message transmission request message (submit_sm) to the single message service center 102 (707), and the single message service center 102 receives the terminal incoming single message. In operation 708, the terminal 104 transmits a long message transmission confirmation message Send_Msg_Ack to the terminal 105. Meanwhile, the extended short message server 101 restores the original long message using the received split information of the short messages, and the host 106 needs to transmit the long text message to the host 106 through the long text message (Send_Msg). In step 710.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

As described above, the present invention divides a long text message that cannot be sent at a time into a single text message into several single text messages, and the divided single text message and the split information are selected or automatically selected by a sender using a conventional single text message service. By transmitting through the receiver and recovering the divided monographs by using the split information back to the long message, it is possible to provide a full-service service by changing the software without major modification to the terminal supporting the conventional single-text service. In addition, it is possible to realize a variety of wireless data services such as telemetry by instructing the terminal and the terminal to perform specific functions such as positioning.
