In order to achieve the above object, the present invention constitutes a network component required by a terminal, a base station, an exchange, and an SMS service center in order to provide an SMS service in a mobile terminal providing a CT-2 direct call service. When the message is transmitted using the function function of the message transmission function to the base station, the called subscriber or the SMS service center through the exchange, and the message received from the SMS service center is referred to as a graphical user interface (GUI) of the terminal. It is characterized by providing a function that can be output to the screen.

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

1 is a block diagram of a hardware and software block to which the present invention is applied and includes an input / output controller 1 and an input / output controller 1 for performing input / output control on a liquid crystal display (LCD) substrate of a terminal. Short message generation unit 2 for generating an SMS message according to a user input under control, a message transfer unit 3 for delivering an SMS message to a lower layer, and a message relay for interworking the SMS message with a call control block of a terminal. 4, a connection manager 5 for managing a link to multiple SMS messages, a general voice call processor 6 for generating a corresponding call processing block according to call classification under the control of the connection manager; Short message Short message call processing generating unit (7), data call processing generating unit (8), link control unit (9), under the control of the link control unit with a unique function inside the terminal and base station and Error control unit 10 for performing detection and restoration of data errors on a radio link, and link management functions based on a link access protocol on a radio channel (hereinafter referred to as LAP-R), and a radio link control unit. It consists of (11).

In order to provide the SMS service, the system processes message delivery (SMS_SUBMIT_REQ), terminal internal memory resource availability (SMS_MEM_AVAIL_REQ), command delivery (SMS_COMMAND_REQ), and message reception (SMS_DELIVER_IND) and status reporting (SMS_STATUS_RESORT).

2 is a detailed flowchart illustrating a method for providing an outgoing SMS in a CT-2 direct call processing system according to the present invention, and describes an inter-block flow for an outgoing SMS message.

In order to use the SMS service in the terminal registered location, select the SMS service selection button (S1).

At this time, by receiving information such as a called number, a transmission message, etc. for transmission in the SMS service processing application block inside the terminal, the service type such as message transmission, memory available resource check, command delivery, etc. is determined to request a service to the corresponding processing block ( S2).

The application process generated by the SMS delivery message request generates a message including a service identifier (SMID) for multiple message services and transmits a primitive (SMS_SUBMIT_REQ) rule to the message delivery layer (S3).

In operation S4, a primitive (SMS_MEM_AVAIL_REQ) for determining whether the main memory is available in the terminal for the SMS service is delivered to the delivery layer.

In addition, a primitive (SMS_COMMAND_REQ) for delivering a command for service control is delivered (S5).

The transport layer adds a message layer of a new layer to the received message, converts the message by the decoding / encoding function, and delivers data to the mobile layer (S6, S7, S8).

In addition, the transport layer adds a message head of a new layer to the received message, converts the message by the decoding / encoding function, and then transfers data to the lower relay layer (S9, S10, and S11).

The relay layer performs a function of delivering a message received from the transport layer to the connection management layer of the terminal.

The connection management layer requests a link connection with a lower radio management layer and a mobility management layer, copies transmission data to a lower layer data management buffer, and sets a service type (S12).

After the service type is set, the delivery message is determined (S13). If the delivery message type is the availability check and command processing message, the processing block is called to perform a function (S14), and the SMS_REPORT_IND primitive is transmitted to the upper layer (S15).

After the transmission message is determined (S13), in the case of the delivery message, data for transmission is copied to the data area of the "CHAR" message, which is a layer 3 message of the lower CT-2 CAI (S16), and a transmission request is made to the radio control block (S16). S17), the radio control block performs a function of transmitting a corresponding message to the base station.

3 is a detailed flow chart of an incoming SMS provided by the CT-2 direct call processing system according to the present invention, in which a mobile terminal receiving a layer 3 message from a wireless channel of a CT-2 destination base station (S18) determines a call identifier of a message. In step S19, the general voice call and the data service call perform the corresponding processing block (S20), and the SMS call is transmitted to the upper protocol layer.

The type of the received message is determined (S21), and if the status report message, the SMS_STATUS_RESORT processing block is performed (S22).

If the message reception type, the received message is copied to the SMS management buffer by the "CHAR" which is the layer 3 message of the CT-2 CAI (S23).

After copying the received message to the SMS management buffer, the connection management layer checks the connection with the lower radio resources and mobility management block (S24).

The relay layer forwards the message received from the lower layer to the transport layer (S25), and forwards the SMS message acknowledgment primitive (TL_DELIVER_ACK) to the application layer from the transport layer (S26).

The SMS service application layer requests the output of the received message to the LCD panel of the mobile terminal (S27), and outputs data in the text output routine (S28).

In response to the status report message request, the application layer inspects the state information inside the terminal and generates a response message through the connection management, relay layer, and transport layer messages (S29, S30, S31, and S32).

The response message is transmitted to the base station through the transport layer, the relay layer, and the connection management layer (S33, S34, S35).

As described above, the present invention defines a protocol stack structure required for providing SMS service in a CT-2 terminal and a primitive definition for message transmission between layers, and “CHAR” defined in CT-2 CAT when transmitting a message through a call channel. By utilizing the layer 3 message, the function to send and receive messages in the dormant state is provided, and therefore, the CT-2 direct call system can provide various services to subscribers.
