The present invention relates to a method for transmitting a one-way SMS message of a mobile communication terminal which reduces unnecessary waste of radio resources by setting an SMS message type field value of a message, a mobile communication terminal for this, and an SMSC therefor.

Due to the rapid development of wireless communication technology and widespread use of mobile communication terminals, mobile communication terminals have established themselves as devices that provide various supplementary services as well as their wireless service.

Short message service (SMS) message service is one of them, beyond the role of a tool for simple message transfer between users performs a variety of functions related to wireless communication services.

For example, a carrier division multiple access (CDMA) service currently provided by China (uni-com) (CU) in China is a kind of user authentication module such as a subscriber identity module (SIM) of a global system for mobile communication (GSM) terminal. The user identity module (UIM) is used to improve the mobility of mobile subscribers, and if a mobile subscriber is provided with a UIM to receive a wireless communication service through a wireless communication network, an SMS message including user information is applied. User registration should be completed by transmitting to wireless communication network.

When performing user registration, it is sufficient to send an SMS message to the wireless communication network and receive an acknowledgment that the message has been received by the base station of the wireless communication network. However, the conventional mobile communication terminal can transmit the SMS message to the wireless communication network only by the bidirectional communication method.

In detail, the conventional SMS message includes an SMS message type field value indicating the type of communication to be performed by the SMS message. In the conventional SMS message type field values, only field values related to bidirectional communication and acknowledgment communication between the mobile communication terminal and the wireless communication network and one-way communication from the wireless communication network to the mobile communication terminal are defined. The field values for communication are not specified.

Accordingly, although there are cases where it is sufficient to send an SMS message to the wireless communication network such as user registration of the mobile communication terminal and receive an acknowledgment that the corresponding message has been received at the base station of the wireless communication network, the conventional mobile communication terminal has a bidirectional communication method. There is a problem that causes the waste of radio resources by sending SMS messages only.

For example, in the case of the automatic registration service currently proposed by CU (china unicom) of China, the SMSC (short message service) of the wireless communication network after the user registration is completed by sending an SMS message to the wireless communication network such as user registration of the mobile communication terminal. The center sends an SMS message notifying the user registration that the user registration has been successfully processed. To this end, a base transceiver system (BTS) of a wireless communication network must open a traffic channel through a calling channel to transmit an SMS message, which causes a considerable waste of radio resources. This is because the mobile communication terminal initially transmits the SMS message set to the two-way communication method for the user registration to the wireless communication network.

An object of the present invention is to solve the above problems, and to reduce the waste of radio resources by enabling SMS messages to be transmitted from the mobile communication terminal to the wireless communication network by a one-way wireless communication method.

Characterized in that it is a mobile communication terminal for transmitting a one-way SMS message including a;

Preferably, the method further includes a message type determination unit that determines a type of wireless communication to be performed according to the generated SMS data and outputs an SMS message transmission command corresponding thereto.

More preferably, the mobile communication terminal is a code division multiple access (CDMA) terminal, and the transmission processor receives a traffic channel through an allocated access channel from a base station and transmits the SMS message through the assigned traffic channel. .

According to another aspect of the present invention for achieving the above object, a storage unit for storing an SMS message type field value indicating the type of wireless communication to be performed by a short message service (SMS) message; Receiving an SMS message including an SMS message type field value configured to perform unidirectional wireless communication from a short message entity (SME) to a wireless communication network in the SME, and performing a predetermined operation according to the SMS data included in the SMS message; SMS message processing unit; characterized in that it is a short message service center (SMSC) for processing a one-way SMS message including.
