Description

Method and Apparatus for Sending Messages in Mobile Communication System

The present invention relates to a method and apparatus for transmitting a message in a mobile communication system. More particularly, the present invention relates to error in a channel when a message service server transmits a message received from an originating subscriber terminal to a called subscriber terminal through a wireless channel. The present invention relates to a message transmission method for preventing a message from being correctly transmitted or lost as a cause.

The message according to the present invention will be used interchangeably with a long message used as a concept including a message including various media (pictures, sounds, videos) as well as a long message meaning a simple long sentence text. That is, the long message according to the present invention refers to all types of messages transmitted between terminals in addition to the voice call service provided by the terminal, and preferably includes not only a simple long message compared to the short message but also a multimedia message. can do.

Short Message Service (SMS) is a type of wireless data communication service that can send and receive text and alphanumeric messages, and the size of messages that can be delivered at one time is quite short. On the contrary, the long message service is a service that can overcome the length limitation of the existing short message and transmit a long message of 500 to 1000 characters, and the specific length is determined according to the performance of the long message service center.

The multimedia message is a service that goes beyond existing text messages and attaches various multimedia data such as texts, images, sounds, and composite images to other mobile phones or e-mails.

Hereinafter, the long message in the present invention will be defined and described as a message including a multimedia message as well as the simple long message described above.

Recently, due to the rapid development of mobile communication, mobile communication subscribers can be provided with various services only by the subscriber terminal. Such services include not only a simple voice call but also a short message service for inputting a simple text message (short message) to the subscriber terminal and transmitting the simple text message to the subscriber terminal of the other party. In addition, the Internet service, which can be accessed using a conventional personal computer or a work station-class computer, can be connected to a subscriber terminal using mobile communication.

Short Message Services currently being serviced in Korea are slightly different depending on the policy of each mobile service provider, but the size of the short message is approximately 80 bytes to 105 bytes (40 to 52 characters in Korean). Is being performed on a limited basis.

The reason why the size of the text message is limited is that in the case of the short message service, a short message is transmitted using voice call traffic, and IS-41C (connection standard between wireless network elements defined by EIA / TIA). This is because the size of the short message is recommended.

Accordingly, techniques of various methods have been provided to overcome the limitations of the text message size that can be transmitted. For example, if the size of the text message is longer than the above-mentioned short message size (these text messages are called long messages), the size for short message transmission (short message transmission unit, i.e., 80 to 105 bytes). Divided into the transmission method has been presented.

However, when the long message is divided into several short message transmission units and received and received, it may be inconvenient to require a user who checks a text message to operate a plurality of subscriber stations. In addition, if any one of the divided short messages is lost, there is a problem in that the meaning of the entire long message cannot be accurately understood.

In addition, when the long message includes various information such as music, video, picture, etc., rather than general text information, transmitting the short text message in units of multiple short message needs to combine several short messages in the subscriber terminal. There was this.

Therefore, as another method for transmitting such a long message, a method of storing the long message in a specific service server and verifying it in a web browser of a subscriber terminal through an internet connection has also been proposed.

However, when stored in the specific service server described above, data communication between the subscriber station and the specific service server is dependent on the wireless Internet, and thus is affected by data errors and transmission speeds that may occur in the transmission channel.

Therefore, when a user checks a long message stored in a specific service server in a subscriber station, if a data error occurs or the quality of transmission speed is low, the long message may be lost.

As described above, a method of storing and confirming a long message in a specific service server (hereinafter, referred to as a long message service server) will be described with reference to FIG. 1.

1 is a diagram illustrating a method of transmitting a long message in a long message service server according to the prior art.

Hereinafter, each step of FIG. 1 will be described in detail.

In step S110, the palm message service server receives the palm message input from the calling subscriber terminal. In this case, the palm message service server is a device capable of performing a web service suitable for wireless mobile communication. For example, the palm message service server may be a server that performs a web service using a WAP (Wireless Application Protocol). The long message service server stores the received long message in a database.

In step S115, the palm message service server sends a uniform resource locator (URL) of the data area in which the palm message is stored to the called subscriber station to notify that the palm message has been received.

In step S120, the palm message service server is connected to the called subscriber terminal via the Internet by executing a web browser provided in the called subscriber terminal. At this time, the called subscriber terminal requests transmission of a long message through the URL of the long message, and the long message service server transmits a long message corresponding to the URL of the long message to the called subscriber terminal.

In step S125, the palm message service server determines whether an error has occurred in data transmission and reception between the palm message service server and the called subscriber station, and thus the transmission of the palm message is failed. This error can often occur when data is transmitted and received over wireless mobile communication as described above.

In step S130, the palm message service server increases the number of palm message transmission attempts. The number of attempts to send a long message is a variable that increases when the transmission fails, and thus the number of attempts to send a long message is limited according to a certain policy since the data cannot be transmitted and received indefinitely until the long message is correctly transmitted.

In step S135, it is determined whether the number of long message transmission attempts is greater than the number of attempts set according to a predetermined policy. If there are still more times to try, the flow proceeds to step S120 to retry transmission of the long message.

In step S140, the palm message service server discards the received palm message. The discarding of the long message is not necessary, but the storage capacity of the long message service server's database has a certain limit. Therefore, the discarding of the long message means the loss of the long message.

As described above, if the long message transmission fails continuously at the long message service server, the long message may not be delivered correctly to the called party and may eventually be discarded, thereby reducing the reliability of the correct sending and receiving of the long message between the called party and the calling party. There was a problem floating down.

An object of the present invention to solve the above problems, in the method of transmitting a long message, a long message in a mobile communication system that prevents a long message to be transmitted from an originating subscriber terminal to a called subscriber terminal due to an error generated in wireless communication. It is to provide a transmission method and apparatus.

Another object of the present invention is to provide such a long message without loss of a separate device in a mobile communication system and a separate software and hardware in a subscriber terminal, so that the long message can be transmitted by e-mail without loss. The present invention provides a method and apparatus for transmitting a long message so that the long message can be checked in a convenient manner.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is a diagram illustrating a network for performing a long message transmission according to an embodiment of the present invention.

2, the elements constituting the network according to the present invention include a base station (BS) 215, a base station controller (BSC) 220, and a short message service server (SMSC). Server (225), Mobile Switching Center (MSC) 230, Home Location Register (HLR) 235, long message service server 250 and e-mail server 255.

Here, the subscriber station 210 is a diagram including a called subscriber and a calling subscriber terminal.

The originating subscriber station and the base station 215 transmit and receive data wirelessly. Such data may be voice, text, video, and picture data, and may include various control signals for adjusting the transmission / reception power of each other or informing the reception of the called subscriber station.

The base station 215 is to provide a wireless mobile communication service for one cell when the area where the mobile communication service is provided is divided into a plurality of cells. The base station 215 receives an up-link signal from a terminal 210 including a called subscriber station and an outgoing subscriber station to perform data control or to control power with the subscriber station 210. Perform.

The base station 215 and other base stations that provide wireless mobile communication services to neighbor cells are managed by one base station controller 220 and transmit data received from the base station 215 and other base stations to the exchange 230. .

The exchange 230 performs a function of connecting a call to the corresponding called subscriber terminal or relaying and transmitting data corresponding to the data received from the calling subscriber terminal.

In addition, the short message service server 225 connected to the exchange 230 performs a function of receiving a short message from the calling subscriber station 210 and sending it to the called subscriber station 265. These short messages are sent and received using the traffic used for voice calls. Therefore, a limited size data is transmitted and received corresponding to the short message size recommended by IS-41C or the short message size according to the policy of the mobile communication service provider. The short message size is set to about 80 bytes to 105 bytes.

Such a voice call or a short message service may not be performed according to the state of a subscribed user. The home location register 235 stores data such as status information, subscriber information, additional service information, location information of the subscribed user, and controls the mobile communication service using the data.

When the receiving subscriber station according to the present invention receives the URL through the short message service server 225 and the exchange 230, it is connected directly to the data network 240 without passing through the exchange 230 to receive a long message. Can be.

The long message service server 250 is a server capable of performing a wireless Internet service. The long message service server 250 receives a long message including text or multimedia data, stores the text in a database, and stores the URL of the stored long message in the short message service server 225. The long message is transmitted to the called subscriber station to be received. In addition, the palm print message service server 250 transmits a palm print message in response to a palm print message request from a called subscriber station.

The long message service server 250 is connected to the Internet network to provide various services. Such a service includes the above-mentioned long message transmission and reception function and an electronic mail transmission function.

The e-mail server 255 performs an e-mail service for the user, and may include a user account, a user password, and a storage area in which the e-mail of the user is stored.

In order to perform such an e-mail service, a server program for transmitting and receiving e-mail data by ESMTP (Extended Simple Mail Transfer Protocol) or SMTP (Simple Mail Transfer Protocol) is executed. Post Office Protocol 2 (POP2), which is used when a user requests to receive an e-mail through a mail usage agent (MUA) (for example, an agent on Outlook, Eudora, or other web services) to check e-mail, It runs a server program that can support Post Office Protocol 3 (POP3), Internet Messaging Access Protocol (IMAP), and so on.

3 is a diagram illustrating a program execution module of a palm message service server according to an embodiment of the present invention.

Referring to FIG. 3, the module executed in the long message service server includes a short message transmitting module 310, an e-mail sending module 315, a long message transmitting and receiving module 320, a database control module 325, and a device control module ( 330). The palm message service server also includes a database 335 for storing various data.

The short message transmitting module 310 generates a short message in a preset format and transmits it to the called subscriber terminal when a long message is received at the long message service server or failure of a continuous long message transmission with the called subscriber terminal occurs.

For example, the short message transmitting module 310 stores the long message received from the calling subscriber terminal in a database and transmits the URL of the stored long message to the called subscriber terminal through the short message service. In this case, the short message is finally transmitted to the called subscriber terminal through the short message service server.

In another example, when the short message transmission module 310 is connected to the called subscriber terminal and transmits a long message, if the continuous transmission failure occurs, the short message is converted into an e-mail format and sent to the recipient subscriber's e-mail address. This fact is transmitted to the called subscriber terminal via a short message. The long message transmission and reception between the long message service server and the called subscriber terminal is performed through the wireless Internet, and the transmission of a long message including an error is more likely to occur because of the large amount of long message. Can be.

As described above, when the number of continuous transmission failures exceeds a predetermined number of predetermined times when the long message is connected to the called subscriber terminal as described above, the e-mail transmitting module 315 converts the long message into an e-mail format to receive the recipient. Send to an e-mail address.

The e-mail address of the called party is preset in the database 335, and the e-mail sending module 315 reads the e-mail address of the called party from the database 335.

The long message transmitting / receiving module 320 receives a long message from the calling subscriber terminal and transmits the long message to the called subscriber terminal. The long message transmitting / receiving module 320 may use a transmission / reception method using the wireless Internet to transmit / receive a long message exceeding the data amount of the short message.

That is, when the calling subscriber requests a long message from the calling subscriber terminal or a personal computer and transmits the long message to the called subscriber terminal, the calling subscriber terminal executes a web browser and transmits the long message to the long message service server. The long message service server receives and stores the long message and notifies the called subscriber terminal of the stored long message in advance. At this time, the called subscriber terminal receives a palm message after being connected to a palm message service server by executing a web browser.

The database control module 325 stores data such as a long message and subscriber information in the database 335, and performs a search and deletion function for such data. Since the database control module 325 generally needs to be able to manage data for information and long messages of hundreds of thousands or millions of subscribers, the database control module 325 is designed by appropriately determining constraints such as calculation cost and speed of a long message service server.

The database 335 is a data storage area in which subscriber information and a long message are stored. The subscriber information includes a mobile identification number (MIN) and an e-mail address of the subscriber. Here, the e-mail address is for transmitting the long message by e-mail when a continuous transmission failure for the long message occurs.

Here, in the embodiment of the present invention, the database 335 is described as being included in the long message service server. However, the database 335 is provided in another server providing data to provide necessary subscriber information using TCP / IP or the like. It can be obtained. For example, it will be appreciated that such subscriber information may be obtained from a database of home locators.

The device control module 330 provides functions such as operation of a long message service server, failure, input / output management with an external connection device, and protocol control for a data transmission / reception function.

4A is a flowchart illustrating a method of transmitting a palm message in a palm message service server according to an embodiment of the present invention.

Hereinafter, the steps of FIG. 4A will be described in detail.

In step S410, the palm message service server receives the palm message from the calling subscriber terminal and stores it in a database. The long message is received by the long message service server in a different way from the short message service.

For example, the short message may be received by a data transmission / reception method through a voice channel in a mobile communication, but the long message may be input through a web browser of a mobile communication terminal and received through a mobile communication network and an internet network.

In another example, if a mobile communication terminal (calling subscriber terminal) is provided with a function of dividing a short message into multiple short messages when the user inputs a long text message, the long message is transmitted through several short message transmission / reception services. Message service server can be received. At this time, of course, the long message service server must combine these short messages into one long message.

Although referred to herein as the calling subscriber terminal, the actual calling subscriber terminal may include various devices. For example, the calling subscriber terminal may include a mobile communication terminal, a personal computer (PC) or a personal digital assistant (PDA) connected to the Internet.

In step S415, the long message service server transmits the URL of the stored long message to the called subscriber terminal through the short message service server. At this time, the long message service server includes the URL of the long message in the short message and transmits it to the called subscriber terminal. In the end, the short message is transmitted to the short message service server and finally sent to the called subscriber terminal.

In step S420, the palm message service server is connected to the called subscriber station and the Internet service. For example, the receiving subscriber who receives the short message including the URL of the long message in step S415 may select the confirmation of the long message after executing the web browser on the called subscriber terminal using the URL of the long message. In response to the selection of the called subscriber, the called subscriber terminal executes a web browser so that the long message service server and the called subscriber terminal are connected through the Internet.

In step S425, the long message service server transmits the received long message to the called subscriber station. At this time, the called subscriber terminal stores the long message in a memory provided therein and displays it on the screen of the called subscriber terminal. Therefore, there is no limit on the size of the actual long message, but there are physical limitations depending on the memory capacity of the called subscriber station.

In step S430, the palm message service server determines whether an error occurs during the palm message transmission. When data communication is actually performed between two devices, data transmission and control are performed by a protocol between each other. In a general communication protocol, data transmitted and received to and from each other is divided into one or several packets and transmitted. One packet includes data and additional data for checking an error on the data. Therefore, the receiving side uses the data and the additional data to determine whether an error exists in the packet, and if the packet contains an error, requests the transmitting side to retransmit.

These errors are less likely to occur due to external physical interference or influence in the transmission and reception connected to the wired network, while the occurrence frequency is high in the data transmission and reception using the wireless mobile communication network as in the embodiment of the present invention. The reason comes from transmitting and receiving data wirelessly with a base station when the called subscriber station is a mobile communication terminal. In wireless data transmission and reception, the effect of the power of a carrier carrying data between two transceivers, and the multipath fading effect in which the reflected wave of the carrier is received at various time intervals from the carrier. ), Many errors occur in the data transmitted / received by various factors such as obstacles such as mountains or buildings, and weather obstacles such as lightning, clouds, and wind.

Of course, a method for correcting and controlling such an error is provided in the called subscriber terminal. However, since the correction performance is limited, the actual mobile communication user frequently experiences disconnection during a call. Therefore, when large data such as a long message is transmitted and received, there is a higher probability of error occurrence.

In step S435, when the long message transmission to the called subscriber station fails, the long message service server attempts to resend the long message. Transmission of the long message by this retransmission is performed in the same manner as in step S425.

In step S440, the palm message service server determines whether the palm message retransmission has failed in the same manner as in step S430.

In step S445, when the retransmission of the long message fails, the long message service server transmits a long message to the e-mail address of the called party. The e-mail address retrieves the recipient subscriber information from the database using the recipient subscriber station number to read the recipient subscriber's e-mail address. Then, the received long message is converted into an e-mail to be sent to the e-mail address using the e-mail address and the originating subscriber information.

In step S450, the long message service server transmits the long message by e-mail, and then generates a short message (e-mail reception notification information) indicating that the received long message is transmitted by e-mail, and transmits it to the called subscriber terminal. Therefore, when the user receives the short message, the user can check the corresponding e-mail, thereby preventing data loss of the long message.

In step S455, the palm message service server deletes the received palm message. The reason for such deletion is to manage a database having a physical capacity limitation and to provide a smooth service.

In the steps of FIG. 4A an embodiment of a processing procedure corresponding to the receipt of a long message of the present invention has been described. Therefore, although only two transmission error determinations have been described as an example in steps S430 and S440, it will be apparent to those skilled in the art that the number of error determinations may be modified depending on the policy for processing a long message in various embodiments. will be.

4B is a flowchart illustrating a method of transmitting a short message in a method of transmitting a long message according to an embodiment of the present invention.

The long message service server transmits brief information to the called subscriber terminal, and the information except for the long message is transmitted through the short message service. Such brief information may include, for example, a URL of a long message or e-mail incoming notification information indicating that the long message is transmitted by e-mail. Thus, the long message service server performs a function of generating and sending such a short message.

Hereinafter, the steps of FIG. 4B will be described in detail.

In step S460 the long message service server generates a short message. The short message includes brief information of 80 bytes to 105 bytes. In one embodiment of the present invention, the short message includes data such as a URL of a long message or e-mail call notification information in the form of a short message.

In step S465, the long message service server transmits the generated short message to the called subscriber station. The short message may include a function of a short message service server in the long message service server so that the short message service server can be directly transmitted to the called subscriber terminal. However, in the present invention, the short message service server transmits the generated short message to the short message service server. do. The short message service server receives the message and transmits it to the called subscriber station.

4C is a flowchart illustrating a method of transmitting a long message using an e-mail in the method of transmitting a long message according to an embodiment of the present invention.

Hereinafter, each step of FIG. 4C will be described in detail.

In step S470, the long message service server stops further transmission and reads the e-mail address of the called party to which the long message is to be transmitted in response to the continuous transmission failure to the called subscriber terminal for the long message.

Such an e-mail address is set in a database of a long message service server, and is searched by a called subscriber station number and read out from the database.

In step S475, the palm message service server converts the palm message into a format that can be sent by e-mail. In the case of e-mail, in the past, text-oriented information has been used to transmit and receive. However, in addition to text, binary files such as moving pictures and pictures may be attached and transmitted. Accordingly, after determining the information included in the long message, the long message is converted by setting the format of the e-mail to be transmitted accordingly.

For example, the format of an e-mail can include a variety of information, such as the sender's e-mail address, reply address, recipient's e-mail address, date, attachment information, and character encoding information. Is set. Such information may be used to control the transmission and reception of electronic mail.

In step S480, the long message service server transmits a long message set in an e-mail format corresponding to the long message to the e-mail address of the called party read in step S470.

FIG. 5 is a diagram illustrating a data structure of a short message including long message incoming notification information according to an embodiment of the present invention.

Referring to FIG. 5, the long message incoming notification information for notifying the recipient of the long message and the URL of the corresponding long message to the called subscriber terminal includes the calling subscriber terminal number 510, the called subscriber terminal number 515, and the URL of the long message ( 520).

The calling party terminal number 510 and the called party terminal number 515 are numbers for identifying the mobile communication terminal of each subscriber, as will be apparent to those skilled in the art, and generally mean a telephone number.

The URL 520 of the long message is an address for transmitting, receiving, extracting or reading a long message stored in the long message service server. In an embodiment of the present invention, the URL 520 of the long message is set in the form of http: // server address / data location in the server so as to transmit and receive a long message by a web service. For example, in the long message of URL 520 shown as "http://lms.ktf.com/cgi-bin/lms_get?id=20021202001234.data" in FIG. 5, "http" is HTTP (Hyper Text Transfer Protocol). ), And "lms.ktf.com" is the domain address of the server that stores the long message. In addition, "/cgi-bin/lms_get?id=20021202001234.data" means "lms_get" with CGI (Common Gateway Interface) software running on the server, and "id = 200212021234.data" means "lms_get". Used as an identifier for data retrieval.

6A is a database table for storing an e-mail address in a palm message service server according to an embodiment of the present invention.

Referring to FIG. 6A, the database includes subscriber terminal numbers and corresponding e-mail addresses.

Herein, the subscriber station number means the called subscriber station number to which the long message is to be finally received, and an e-mail address is set accordingly. For example, if the called party's terminal number that the long message service server continuously tried to send the long message was 016-201-5678, the long message was sent to the corresponding e-mail address mymail@ktf.com in response to the continuous sending failure. do.

FIG. 6B is a diagram illustrating a short message including e-mail incoming notification information indicating that a long message is transmitted by e-mail according to an embodiment of the present invention.

The e-mail incoming notification information includes simple text information in a preset format and a URL of an e-mail transmitted to the e-mail address of the called party. Here, the short message is transmitted from the long message service server to the called subscriber terminal including the e-mail incoming notification information.
