The present invention relates to an apparatus and method for transmitting and receiving SMS messages, and more particularly, to an apparatus and method for transmitting and receiving SMS messages by wirelessly and stably transmitting an SMS message by connecting to a server through PCI or USB.

In general, an SMS (Short Message Service) supplementary service is a service that provides additional information to a subscriber to an SMS basic service or performs a function other than basic message delivery through a special type of message.

In order to provide a variety of SMS supplementary services, it is easy to add or delete supplementary services, and create a service suitable for subscriber preferences to promote convenience of subscribers.

FIG. 1 is a block diagram showing the configuration of an SMS supplementary service processing system in a general personal communication service network. As shown in FIG. 1, a terminal 101 for a subscriber to transmit an supplementary service request and receive a short message as a result of supplementary service is shown. And a base station / base international controller (BSC / BTS) 102 for allowing the terminal 101 to access a network using a wireless protocol, and request for additional services from the base station / base international controller 102 Additional service request and requested additional service from the personal communication exchange / visitor information processing system (PCX / VLR) 103 for relaying / exchanging short messages resulting from the supplementary service, and the exchange / visitor information processing system 103 A short message processing system (SMC) 105 for temporarily storing and transmitting the short message data for processing the short message processing system (SMC) 105 According to the additional subscriber's request for supplementary service, the supplementary service integrated management system (VAS) 106 which performs SMS supplementary service management such as overall subscriber management, billing management and operation management for all SMS supplementary services, and supplementary service integrated management One or more SMS additional service units (ESME) 107 for generating a short message corresponding to the requested supplementary service under the instruction of the system (VAS), and providing the location of the called terminal for short message processing, and the called terminal is short. Subscriber information processing system (HLR) 104 for notifying whether a message can be received.

The terminal 101 and the SMS supplementary service device (ESME) 107 generate and receive a short message and perform a function of terminating the delivery situation.

In particular, the terminal 101 may have a function of temporarily storing a short message and a short message notification function to process a short message in addition to a general call processing and location registration function.

One SMS supplementary service is implemented in one ESME 107, and the ESME 107 may exist inside or outside the supplementary service integration management system (VAS) 106 depending on the characteristics of the supplementary service.

The Short Message Processing System (SMC) 105 can additionally handle SMS basic services, and also performs a gateway function for short message processing, and exchange / visitor information processing system (PCX / VLR) 103 And performs an MAP (Mobile Application Part) processing function for interworking with the subscriber information processing system (HLR) 104 and a protocol (X.25) matching function for interworking with an external service provider.

In particular, it performs a VMS access function for the VMS (Voice Mail System) notification function and a processing function (X.400) for the E-mail notification function.

The personal communication exchange / visitor processing system (PBX / VLR) 103 is connected to the base station / base international controller 102 and the short message processing system (SMC) 105, and performs routing to perform a short message. It performs relay / exchange and identifies short messages.

Here, a method of inputting the text message will be described.

First, the user presses a text message function button in the menu to switch to the text message transmission / reception function mode.

Then, after inputting the telephone number of the other party to send the text, the text to be sent is input using the text on the keypad.

Then, when the text message is completed, the text message is transmitted by pressing the 'SEND' button.

Here, the transmission text may be set to urgent or normal to select a transmission speed, and group transmission may be performed to a plurality of counterparts.

However, the SMS message service using the terminal described above has only one-to-one transmission, but it takes a long time to transmit a single message to those who are not used to key input of the terminal.

Therefore, in recent years, a method of transmitting a short message by connecting to the Internet through PC has been introduced, which causes a problem of information leakage to a customer on a weak Internet.

Accordingly, a method of connecting a terminal for short transmission to a server using a serial port is used.

However, as described above, the data transmission method using the server and the serial port is unstable, and additional devices and wires are required to transmit to many ports, resulting in increased cost and short text. It is difficult to build a transmission server.

The present invention has been made to solve the above problems, by connecting to the server via PCI or USB, by sending an SMS message wirelessly, SMS messages to send and receive SMS messages in real time and stable in various application environments in real time It is an object of the present invention to provide an apparatus and method.
