FIG. 1 illustrates an embodiment of a service network for providing message information using a mobile communication network, and includes a user terminal device 100, a PCS network 110, a user network 120, and a user service center 130. It consists of.

The user terminal device 100 includes a mobile message terminal 102 and a message mobile terminal 104. The mobile message terminal (MMT) 102 is a service terminal of a mobile communication service network, requires authentication of the terminal management device 116, and transmits message information when authenticated. In addition, the mobile message terminal 102 is physically connected to the message mobile terminal 104, and is identified by a unique number (ID) assigned by the communication network operator. Here, 'message information' refers to information exchanged between the message information processing apparatus 120 and the mobile message terminal 102 using a message service provided by the mobile communication network.

The Message Personal Station (MPS) 104 refers to a user terminal in which a function for a message service is added in addition to a normal mobile terminal function. The message mobile terminal 104 supports the authentication procedure required by the mobile communication network and stores an authenticated message terminal number (ID) to perform an authentication function for all messages received from the mobile message terminal 102. In addition, the message service is stopped from the mobile message terminal 102 which has not been authenticated, and the mobile message terminal 102 has a physical connection. It also supports call processing procedures for message services, and adds or interprets a teleservice ID. In addition, it checks whether the physical connection with the message terminal 102 and reports to the terminal management device 116 if necessary. In addition, it supports the general call connection request from the message terminal 102, and should be authenticated by the terminal management device (116).

The PCS network 110 is a type of mobile communication network, and includes a base station 112, an SMS center 114, and a message terminal management device 116. The base station 112 is a base station of a normal mobile communication network, and the SMS center 114 is a normal SMS center for providing a short message service, and adds or interprets a teleservice ID.

The message terminal management device (MTC) 116 is located in the mobile communication network, performs authentication and management functions for the user's mobile message terminal 102, and transmits the user's message information to a message information processing device ( 122) play a role of giving and receiving. In addition, the message terminal management device 116 can periodically check the authentication of the user terminal or the message terminal 102, and rejects the call to the unauthenticated message terminal 102 during the outgoing signal of the information processing apparatus 122. . It also performs data management functions such as MIN, ESN, and attributes, and monitors traffic conditions by message service. When total traffic occurs above the set threshold, the message service function is stopped for all or some message terminals. Stop message service or control the throughput for message terminals that generate traffic above a defined threshold.

The user network 120 specifically corresponds to the message information processing apparatus 122. The Message Information Processing Center (MIPC) 122 refers to equipment installed by a user to deliver message information to the mobile message terminal 102. The message information processing center (MIPC) 122 is connected to the terminal management device 116 to provide a message service. do. And additional service using message information is defined and used by user.

Specifically, the user service center 130 corresponds to the message information processing device terminal 132, and the message information processing device terminal 132 uses a service provided by the message information processing device 122 to the mobile message terminal. It refers to the entity that exchanges information with 102. The additional service using the message information is defined and used by the user.

FIG. 2 is a diagram illustrating a state transition diagram between the mobile terminal 104 and the message terminal 102 in the message service network shown in FIG. 1, and describes a state for a message service between the mobile terminal and the message terminal.

First, the service unavailable state 200 indicates that the message information service cannot be used in a state where authentication for the message terminal 102 is denied.

The authentication state 210 by the management device is a message terminal authentication state by the network, and refers to an authentication step performed by the terminal management device 116 to determine whether to provide a message service to the user's message terminal 102. When the message terminal 102 is initially connected to a network or uses another mobile terminal, the message terminal 102 automatically performs a message authentication procedure.

The message terminal authentication state 230 by the terminal refers to an authentication step for a message received from the message terminal 102 by the mobile terminal 104 after the authentication process by the network is completed. The message information received from the unauthenticated message terminal is discarded and the service unavailable message is transmitted to the message terminal.

The service stop state 250 is a state in which the message service is suspended, and is composed of a terminal detachment state 252 and a call breakaway state 254. The terminal disconnected state 252 is a physical connection released state, and the message service provided by the mobile communication network cannot be used while the physical connection between the mobile terminal 104 and the message terminal 102 is released. In the out-of-talk state 254, the mobile terminal 104 is located in the out-of-talk area of the mobile communication network, and the message service is suspended.

The idle state 220 may receive a message service provided by the mobile communication network in a state where a physical connection between the mobile terminal 104 and the message terminal 102 is normal. The service state 240 refers to a state in which message information is transferred between the user's message terminal 102 and the information processing apparatus 122.

On the other hand, according to the present invention, a method of initial setting of the service terminal connected to the mobile terminal of the service system using a mobile communication network will be described. First, the mobile terminal 104 recognizes the connection of the service terminal 102. Upon recognition, the service terminal 102 transmits a setting request message for initial setting to the mobile terminal 104. When the mobile terminal 104 receives the setting request message, the mobile terminal 104 transmits a setting request confirmation message to the service terminal 102. The setting request message includes information on a transmission method and information on a service type provided by the mobile communication network, and the information on the transmission method includes baudrate, data bit information, parity information, and stop bit.

The method for initializing the service terminal 102 will be described in detail with reference to the above-described description of the service network and the state descriptions of the mobile terminal 104 and the message terminal 102. 3 shows an initial setup method (startup procedure) for connection.

If a frame error occurs more than five times in succession, the start procedure is entered. The message terminal and the mobile terminal are set to zero speed set. The message terminal 102 transmits a setup request message during T_start_con. If a setup confirmation or reset request message is not received during T_start_con, a setup error message is output and T_start_con = 0.

The mobile terminal 104 analyzes the setting request message, if possible, activates T_sync, transmits the setting confirmation message 10 times, sets the setting speed, and transmits the frame synchronization confirmation message. If no frame sync signal is received in T_sync, it returns to initial setting. The message terminal 102 stops transmitting the setting request message upon receiving the setting confirmation message, activates T_sync_con, transmits the frame synchronization signal 10 times to the setting value, and transitions to the standby state. If no frame synchronization confirmation message is received in T_sync_con, the mode returns to the initial setting mode. The message terminal 102 transitions to the standby state upon receiving the frame synchronization signal. The mobile terminal 104 analyzes the setup request message and transmits a reset message if it is impossible. The message terminal 102 receives a setting request message and transmits a setting confirmation message if the setting is possible. The setup procedure takes place.

Meanwhile, the frame structure of the message transmitted between the mobile terminal 104 and the message terminal 102 according to the initial setting method (start-up procedure) can be configured as follows. First, Table 1 shows an example of a frame structure of a setup / reset request message that a message terminal / mobile terminal is transmitted to an initial setup / reset to a mobile terminal / message terminal.

4 is a diagram illustrating an outgoing signal processing procedure of a message terminal, and an outgoing signal processing of a mobile terminal will be described with reference to FIG. 4.

First, the operation of the message terminal is as follows. If there is a message information transfer request from an internal higher level protocol, a message information transfer request is made to the mobile terminal. When a reception confirmation is to be received from the mobile terminal, the "request request" field is set to "0x01" and the timer is operated. If a message information delivery confirmation is notified from the mobile terminal within a predetermined time T_MMT_TX, the message terminal transitions to the standby state and the message transmission is completed. In addition, if the message information delivery confirmation notification is not received within a predetermined time T_MMT_TX, the message information delivery request is retransmitted. If the message for confirming delivery of mesh information is not received until three times of retransmission, it is notified that the service is not available through a higher protocol.

Next, the operation procedure of the mobile terminal is as follows. When the message information transfer request is received from the message terminal, the message terminal authentication procedure is performed. If the result of authentication is successful, the message information is transmitted to the SMS center. If a message information delivery request is received from the message terminal, the message information delivery confirmation message is transmitted to the message terminal if the message request message is transmitted.

5 is a diagram illustrating a message terminal hand signal processing procedure. Referring to FIG. 5, a hand signal processing process of a message terminal will be described. First, when the mobile terminal receives the SMS message, the mobile terminal checks the teleservice ID to determine the user message information. Then, if the SMS message is determined to be the message information of the user, the message terminal confirms that the normal standby state and delivers the message information. After that, when the physical connection is released or the service is not available, the information processing apparatus is notified of the service failure. The message terminal transmits the message information from the mobile terminal in the normal standby state and transmits it to the upper protocol for processing.

Meanwhile, the frame structure of the message used in the call signal processing and the hand signal processing will be described. The reverse message information transfer request message is used to transmit message information from a message terminal to a mobile terminal, and an example of the frame structure thereof is shown in Table 5 below.

On the other hand, according to the present invention, a message transmission amount control method of a service terminal connected to a mobile terminal of a service system using a mobile communication network will be described. The message transmission amount control method is divided into a method of suspending a service and a method of adjusting a message transmission amount.

First, a method of suspending a service is as follows. The service terminal management device 116 monitors the amount of message traffic of the service terminal 102. When the amount of traffic exceeds a predetermined value, the service is suspended and the amount of the message traffic is monitored, and when the amount of the traffic is smaller than the predetermined value, the service is resumed. The service suspension is performed as follows. The service terminal management device 116 transmits a service pause request to suspend a service to the mobile terminal. The mobile terminal 104 transmits the service pause request message to the service terminal when receiving the service pause request message. When the service terminal 104 receives the service pause request message, the service terminal 104 suspends message information transmission and transmits a service stop confirmation message to the mobile terminal 104. When the mobile terminal 104 receives the message service stop confirmation message, the mobile terminal 104 transmits it to the service terminal management device 116. The service resumes as follows. The message terminal management device 116 monitors the amount of the message traffic and transmits a service start request message to the mobile terminal 104 when it is smaller than a predetermined value of the traffic. When the mobile terminal 104 receives the service start request message, the mobile terminal 104 transmits the service start request message to the service terminal 102. When the service terminal 102 receives the service start request message, the service terminal 102 transmits a service start request confirmation message to the service terminal, and resumes service. If the mobile terminal 104 does not receive a confirmation message from the service terminal management device 116 within a predetermined time, the mobile terminal 104 retransmits the service stop confirmation message.

Next, a process of adjusting the message transmission amount will be described. First, the service terminal management device 116 monitors the amount of message traffic of the service terminal 102. When the amount of traffic is out of a predetermined range, the service terminal management device 116 transmits a message transmission amount control request message to the mobile terminal 104. When the mobile terminal 104 receives the message volume control request message, the mobile terminal 104 sets the message transmission rate and transmits a message volume control request message to the service terminal 102. The service terminal 104 receives the message transmission amount control request message and stores it, and transmits a message transmission amount adjustment confirmation message to the mobile terminal 104. The mobile terminal 104 then transmits a transmission control confirmation message to the service terminal management device 116.

A method of controlling a message transmission amount of the service terminal 102 will be described in detail with reference to the above-described description of the service network and the state descriptions of the mobile terminal 104 and the message terminal 102. FIG. 6 illustrates a process in which the terminal management device 116 analyzes the traffic and adjusts the traffic when the traffic control for the message service is required due to the overload of the mobile communication network.

First, the service suspension procedure will be described. When the message service request stop message is received from the terminal management device 116, it notifies the message terminal and stops transmitting message information until the message service start message is received. When the message terminal 102 receives the message service stop message, the message terminal 102 pauses the message information transmission and delivers a service stop confirmation message. The mobile terminal 104 transmits the message service stop confirmation message to the terminal management device 116.

Next, the traffic conditioning procedure will be described. When the message terminal 104 receives the message transmission control request message, it stores it and delivers it to the message terminal 102. The message information transmission amount by SMS call is kept below the stored value. When the message terminal 102 receives the message volume control request message, it stores it and delivers a message volume control confirmation message. The amount of message information transmission is less than or equal to the stored value. When the mobile terminal 104 receives the message transmission control confirmation message, the mobile terminal 104 transmits it to the terminal management device 116.

Meanwhile, the frame structure of the message related to the traffic control will be described. The service suspension request message is used to notify the message service suspension request from the message terminal management apparatus. An example of the frame structure is shown in Table 9 below.
