In order to more easily understand a method for activating a user terminal using a communication network in a wireless communication system according to the present invention, the state of the user terminal 110 in the IPLS (IP Location Server) 145 is managed as five types as follows. Let's define.

First, as an active state, which is a state in which both a session and a connection are established between the user terminal 110 and the data management system 115, the user terminal 110 performs PDSN (Packet Data Serving). Node) 130 and the PPP configuration is also made. In addition, this means that the IMSI and IP address of the user terminal 110 are also registered in the DNS (Domain Name Server) 140.

In the present specification, the session (session) is established state refers to a state in which an identifier that can identify the user terminal 110 is assigned in the Session Control and Mobility Management (SCMM) 125, the connection (connection) The set state refers to a state in which a traffic channel for data transmission and reception is allocated between the user terminal 110 and the data management system 115, and the data transmission is possible from the data management system 115 to the user terminal 110. It will be defined as.

Second, as a dormant state, the connection is terminated after the expiration of the Packet Data Inactivity Timer between the user terminal 110 and the data management system 115, and only the session is terminated. It means the set state. However, the packet data serving node (PDSN) 130 and the PPP settings are maintained, and the IMSI and IP address of the user terminal 110 registered in the domain name server (DNS) 140 are also maintained.

Third, as an idle state, this means a state in which only a session is established between the user terminal 110 and the data management system 115. However, the packet data serving node (PDSN) 130 and the PPP configuration are terminated, and the IP address is also deleted from the domain name server (DNS) 140 and compared with the previous dormant state.

Fourth, as a parking state, this means a state in which even a session is terminated between the user terminal 110 and the data management system 115.

Fifth, it is a state in which the power of the user terminal 110 is turned off as an inactive state, and the PDSN 130 and the PPP configuration are terminated, and the IP address information is also deleted from the DNS 140.

Finally, as a non-state, this means that the user terminal 110 is not registered in the IPLS (IP Location Server) 145.

In addition, in the case of the parking state or the non-state described above, the connection is only disconnected or not registered in the relationship with the data network, and the connection may be established in the relationship with the voice network. .

In step 160, the data management system 115 checks whether the location information or the status information of the user terminal 110 has changed, and if there is a change, registers the update. A method of updating and managing terminal information related to location information or status information of the user terminal 110 in the data management system 115 will be described in detail later with reference to FIG. 3.

In operation 162, the data management system 115 checks whether a message to be transmitted to the user terminal 110 exists (that is, whether there is a message transmission request). As a result of the check of step 162, if there is a message transmission request, the flow proceeds to step 164, and if not, the flow proceeds to step 160 again.

In operation 164, the data management system 115 checks whether the state of the user terminal 110 to receive the message transmitted from the data management system 115 is an active state.

If the state of the user terminal 110 is an active state as a result of the check of step 164, the flow proceeds to step 168 to determine whether an IP address assigned to the user terminal 110 is found.

If the IP address assigned to the user terminal 110 is found as a result of the check of step 168, the operation of transmitting the message to the searched IP address is performed (to be described in detail later with reference to FIG. 4). If the IP address is not found, the corresponding operation is performed accordingly (this will be described in detail later with reference to FIG. 5).

If the state of the user terminal 110 is not an active state with reference to step 164 again, the process proceeds to step 170 and determines whether the state of the user terminal 110 is a dormant state. .

If the state of the user terminal 110 is a dormant state as a result of the check in operation 170, the data management system 115 may actively transmit data to the user terminal 110. Transmitting the data after converting the state of the 110 to the active state (which will be described in detail later with reference to FIG. 6).

Referring back to step 170, if the state of the user terminal 110 is not a dormant state, the flow proceeds to step 172 to check whether the state of the user terminal 110 is in an idle state. do.

A case in which the state of the user terminal 110 is in an idle state as a result of the check of step 172 will be described in detail later with reference to FIGS. 7A to 7C, otherwise (inactive state). , A parking state) will be described in detail later with reference to FIG. 9.

Hereinafter, when the state of the user terminal 110 is changed or the position of the user terminal 110 is changed through the mutual operation between the user terminal 110 and the SCMM 125, the SCMM 125 performs the corresponding user terminal 110. In order to register and manage the information required by the IPLS 145 by transmitting the location or status information of the IPLS 145, the user terminal 110 related information registration method will be described.

Next, an operation performed by the data management system 115 to apply the user terminal activation method using the communication network in each state described above will be described with reference to related drawings. Through this, it will be easier to understand each device included in the data management system 115 and a user terminal activation system using a communication network.

3 is a data flow diagram illustrating a method of updating related information when a state or location of a user terminal is changed in a data management system according to the present invention.

With reference to the data flow diagram shown in FIG. 3, the user terminal 110 is moved from a first state (eg, an active state, etc.) to a second state (eg, a dormant state). In the case of changing to an idle state, a parking state, or an active state, the location of the user terminal 110 is changed, and the location registration for the user terminal 110. Let's take a look at how to deal with failure cases.

However, in describing each step performed in each case, the same reference numerals shown in FIGS. 3 and 3 will be used the same.

First, a case in which the state of the user terminal 110 is changed from a first state (for example, an active state or the like) to a dormant state will be described.

In operation 175, a session is established between the user terminal 110 and the session control and mobility management (SCMM) 125. In other words, an identifier that can be identified is assigned to the user terminal 110 in the SCMM 125 area.

SCMM 125 is a device that performs session management and terminal management functions for call origination and call reception using 1xEV-DO. At some point, the state information of the user terminal 110 is in a dormant state. In case of change to), the SCMM 125 confirms that the state information of the user terminal 110 has been changed to a dormant state (step 180).

In addition, in step 185, the SCMM 125 may be installed with a large number of subscribers' IMSI numbers and SCMM IDs (SCMMs may be installed in the same number as the base stations in the voice network. ), A terminal information update request including status information (ie, idle state) is transmitted to the IPLS 145.

In step 190, the IPLS 145 recognizes that the current state of the user terminal 110 is a dormant state by using the received terminal information update request, and the state information of the user terminal 110 is idle. Update registration to (dormant state) (that is, update registration of the state of the IMSI number to the dormant state).

For example, the format of data stored in connection with each user terminal 110 in order to manage the status information or the location information of the user terminal 110 in the IPLS 145 is an IMSI number storage area, the user terminal 110. A status information storage area, a reason code area (i.e., an error code area) for recording the cause in case of an update registration failure, and the like.

In operation 195, the IPLS 145 transmits registration result information indicating that the update registration operation for the user terminal 110 is normally completed to the SCMM 125 in step 190.

Next, the case where the state of the user terminal 110 is changed from the first state (for example, the active state, etc.) to the idle state will be described.

If a session is established between the user terminal 110 and the SCMM 125 in step 175, and the state information of the user terminal 110 is changed to an inactive state at some point, the SCMM 125 is performed in step 180. Confirms that state information of the user terminal 110 has been changed to an idle state.

In operation 185, the SCMM 125 transmits a terminal information update request including the IMSI number, the SCMM ID, and the status information (ie, the inactive state) of the subscriber to the IPLS 145.

In step 190, the IPLS 145 recognizes that the current state of the user terminal 110 is in an idle state by using the received terminal information update request, and deactivates the state information of the user terminal 110. Update registration to (idle state).

In operation 195, the IPLS 145 transmits registration result information indicating that the update registration operation for the user terminal 110 is normally completed to the SCMM 125 in step 190.

Next, the case where the state of the user terminal 110 is changed from the first state (for example, the idle state, etc.) to the active state will be described.

If a session is established between the user terminal 110 and the SCMM 125 in step 175, and the state information of the user terminal 110 is changed to an active state at some point, the SCMM 125 is performed in step 180. Confirms that state information of the user terminal 110 has been changed to an active state.

In operation 185, the SCMM 125 transmits a terminal information update request including the IMSI number, the SCMM ID, and the status information (ie, the active state) of the subscriber to the IPLS 145.

In step 190, the IPLS 145 recognizes that the current state of the user terminal 110 is an active state by using the received terminal information update request and recognizes the state information of the user terminal 110 in an active state. Register for update with (active state).

In operation 195, the IPLS 145 transmits registration result information indicating that the update registration operation for the user terminal 110 is normally completed to the SCMM 125 in step 190.

Next, a case where the state of the user terminal 110 is changed from the first state (for example, the active state) to the parking state will be described.

If a session is established between the user terminal 110 and the SCMM 125 in step 175, and the state information of the user terminal 110 is changed to a parking state at some point, the SCMM 125 is performed in step 180. Confirms that the state information of the user terminal 110 has been changed to a parking state.

In step 185, the SCMM 125 transmits a terminal information update request including the subscriber's IMSI number, the SCMM ID, and status information (ie, the revocation status) to the IPLS 145.

In step 190, the IPLS 145 recognizes that the current state of the user terminal 110 is a parking state by using the received terminal information update request, and releases state information of the user terminal 110. Register for renewal with (parking state).

In operation 195, the IPLS 145 transmits registration result information indicating that the update registration operation for the user terminal 110 is normally completed to the SCMM 125 in step 190.

Next, a method of newly registering the location information of the user terminal 110 when it is changed will be described. This means that when each SCMM 125 is configured to manage only the user terminal 110 included in a certain area, the position of the user terminal 110 is different from the other SCMM 125 in the area managed by the first SCMM 125. In this case, the location information of the user terminal 110 is updated and registered when it is moved to the area to be managed.

If a session is established between the user terminal 110 and the second SCMM 125 in step 175, the second SCMM 125 determines that the user terminal 110 was managed by the first SCMM 125 in step 180. Confirm that you have moved from the area.

In step 185, the SCMM 125 transmits a terminal information update request including the IMSI number, the SCMM ID, and the status information of the subscriber to the IPLS 145.

In step 190, the IPLS 145 recognizes that the second SCMM 125 newly manages the user terminal 110 by using the received terminal information update request, and updates and registers location information of the user terminal 110. do.

In operation 195, the IPLS 145 transmits registration result information indicating that the update registration operation for the user terminal 110 is normally completed, to the second SCMM 125.

Finally, a description will be given of a processing method when the status information change or location registration for the user terminal 110 fails.

In step 175, a session is established between the user terminal 110 and the session control and mobility management (SCMM) 125, and at some point, the state information of the user terminal 110 changes from the first state to the second state. Or when the location of the user terminal 110 is changed, the SCMM 125 checks the changed state information or the location information of the user terminal 110 in step 180.

In step 185, the SCMM 125 transmits a terminal information update request including the IMSI number, the SCMM ID, and the second status information (or location information) of the subscriber to the IPLS 145.

In step 190, the IPLS 145 recognizes that the state information or the location information of the user terminal 110 has been changed by using the received terminal information update request, and updates the state information or the location information of the user terminal 110. Attempt to register.

However, if the update registration operation of step 190 cannot be performed normally (for example, when it is determined that the status information of the IMSI number cannot be changed, etc.), the process proceeds to step 195, and the IPLS 145 receives the update registration failure information. A cause code is transmitted to the SCMM 125.

Hereinafter, referring to FIGS. 4 to 9, a method of allowing data management system 115 to actively transmit data at every necessary time regardless of whether the current state of the user terminal 110 is active or not, will be described. Let's look at it.

4 is a data flow diagram illustrating a method for transmitting data to a user terminal in which the data management system according to the present invention is active.

Referring to FIG. 4, if there is a message to be transmitted to the mobile communication service subscriber in the Long Message Entity (LME) 155, the LME 155 transmits an LMS (LMS) to the Long Message Service Center (LMSC) 150 in step 210. Long Message Service) Send a service request (ie, LMS message transfer request).

In step 215, the LMSC 150 checks the validity of the subscriber's International Mobile Subscriber Identity (IMSI) number. If the IMSI number is valid, the LMSC 150 proceeds to step 220 to the IP Location Server (IPLS) 145 for the subscriber. Sends a request for status information of the user terminal 110 (in a subsequent step, to identify the subscriber, the IMSI number of the subscriber may be transmitted and received together with the request information, etc., but the description on the transmission and reception of the IMSI number will be omitted). .

The IPLS 145 checks the state information of the user terminal 110 at step 225 to confirm that the current state of the user terminal 110 is an active state, and then proceeds to step 230 and performs the mobile communication service. The IP address request is sent to the Domain Name Server (DNS) 140 to know the IP address of the subscriber (ie, assigned to the user terminal).

The DNS 140 searches for the IP address information allocated to the user terminal 110 in step 235, and proceeds to step 240 and transmits the searched IP address information for the user terminal 110 to the IPLS 145.

In step 245, the IPLS 145 transmits the terminal information including the IP address information and the terminal state information (that is, the active state) received through the step 240 to the LMSC 150.

The LMSC 150 recognizes that the LMS message can be transmitted to the user terminal 110 by using the terminal information received from the IPLS 145, and the call notification information to the user terminal 110 using the communication network in step 250. Send it.

When the incoming call request information is input from the subscriber (for example, when the subscriber uses the URL callback function), the user terminal 110 proceeds to step 255 and transfers the incoming call request information to the LMSC 150. send.

Thereafter, the LMSC 150 transmits the LMS message (ie, the long message) requested from the user terminal to the user terminal 110 in step 260.

For example, a method of transmitting an LMS message from the LMSC 150 to the user terminal through steps 250 through 260 will be described below.

As is generally done by downloading a background screen of the mobile communication terminal, the LMSC 150 receives a guide message (for example, "Hong Gil Dong has received a long message" to the user terminal 110 through step 250. Please press the call button ", etc.).

Then, if the subscriber (eg, Hong Gil-dong) wants to check the long message, the long message is selected by selecting a "call button" from the key buttons included in the user terminal 110 as indicated in the guide message in step 255. The confirmation request is sent to the LMSC 150.

When the long message confirmation request is received from the mobile communication terminal, the LMSC 150 transmits a long message corresponding to the long message confirmation request (eg, a video advertisement, a short message including a video) through the user network. Transmit to 110.

5 is a data flow diagram illustrating a processing method when the data management system according to the present invention does not retrieve an IP address assigned to a user terminal when transmitting data to an active user terminal.

Referring to FIG. 5, in the following description of the processing method when the IP address assigned to the user terminal cannot be retrieved, the same reference numerals as shown in FIG. 4 are the same for the same process as the process described with reference to FIG. 4. (Step 210 to step 230), and description thereof will be omitted to avoid duplication.

Referring to FIG. 5, when the IP address request is received from the IP Location Server (IPLS) 145 in step 230, the DNS proceeds to step 310 to search for an IP address assigned to the user terminal.

If the search result of step 310 does not find an IP address assigned to the user terminal (that is, the corresponding IP address is not found when searching using the subscriber's IMSI number), the operation proceeds to step 315. Proceed to set the IP address for the user terminal to a predetermined number (for example, "0. 0. 0", etc.), and then set the IP address information and the situation (i.e., corresponding to the user terminal). Processing result information including cause code information previously specified for the IP address cannot be found) is transmitted to the IPLS 145.

In step 320, the IPLS 145 uses the processing result information received in step 315 to transmit the terminal information including the IP address information and cause code information (i.e., code information corresponding to the absence of the IP address) to the LMSC 150. To send.

Further, in addition to the case where the processing result information including the content that the IP address cannot be found from the DNS 140 is received, the processing result information is received from the DNS 140 for a predetermined time (for example, 1 minute, etc.). If not, the IPLS 145 transmits the reason code information (that is, the processing result reception waiting timeout information) corresponding to the situation to the LMSC 150 together with the IP address information set to a predetermined number.

6 is a data flow diagram illustrating a method of changing a user terminal in an active state to an active state so that the data management system according to the present invention can transmit data to the user terminal by itself.

When the user terminal 110 is in the dormant state, the connection is terminated as compared with the active state. However, since the PDSN (Packet Data Serving Node) 130 and PPP settings are maintained, the IMSI and IP address of the user terminal 110 registered in the Domain Name Server (DNS) 140 are also maintained. In order to enable data transmission to the terminal 110, only a connection needs to be reset.

Referring to FIG. 6, in the method of changing a user terminal in a dormant state to an active state in the data management system itself, the same matters as the process described above with reference to FIG. 4 will be described. The same reference numerals shown in FIG. 4 are given the same (steps 210 to 230), and description thereof will be omitted to avoid duplication.

In step 410, the IP Location Server (IPLS) 145 confirms that the state of the user terminal 110 of the mobile communication service subscriber is in a dormant state, and then proceeds to step 415 in which the mobile communication service subscriber (i.e., In order to know the IP address of the user terminal), the IP address request is transmitted to the Domain Name Server (DNS) 140.

The DNS 140 detects IP address information allocated to the user terminal 110 using the IMSI number of the mobile communication service subscriber in step 420, and then proceeds to step 425 to retrieve the retrieved IP address information from the IPLS 145. To send).

In step 430, the IPLS 145 includes terminal information including IP address information of the user terminal 110 received through step 425 and state information (ie, idle state) of the user terminal 110 checked through step 410. To the Long Message Service Center (LMSC) 150.

The LMSC 150 confirms that the current state of the user terminal 110 is in the idle state by using the state information of the user terminal 110, and receives the user terminal 110 received from the IPLS 145 through step 435. Call notification information is transmitted to the PCF (Packet Control Function) 120 using the IP address.

In step 440, the PCF 120 establishes a connection with the user terminal 110 to change the state of the user terminal 110 from a dormant state to an active state capable of data transmission. Do this.

After completing the connection setup with the user terminal 110 in step 440, the PCF 120 and the incoming call notification information received from the LMSC 150 in step 445 (that is, IP address information required to receive a long message) and Incoming notification information is transmitted to the corresponding user terminal 110 through a communication network.

When the incoming call request information is input from the subscriber, the user terminal 110 transmits the incoming call request information input in step 450 to the LMSC 150.

Thereafter, the LMSC 150 transmits the LMS message (ie, the long message) requested from the user terminal to the user terminal 110 in step 455.

Subsequently, a brief description will be made of a processing method when the user terminal 110 does not retrieve an IP address assigned to the user terminal 110 when the user terminal in an idle state is changed to an active state so that the data management system may transmit data to the user terminal. Let's do it.

In the case where the user terminal in the idle state is changed to the active state in the data management system, the data flowchart illustrated in FIG. 5 will be described. For convenience of description, the same reference numerals shown in FIG. 5 will be used.

Referring to FIG. 5, when there is a message to be transmitted to a mobile communication service subscriber in a long message entity (LME) 155, in step 210, the LME 155 is a long message service center (LMSC) 150. Message Service) Send a service request (ie, LMS message transfer request).

In step 215, the LMSC 150 checks the validity of the subscriber's International Mobile Subscriber Identity (IMSI) number. If the IMSI number is valid, the LMSC 150 proceeds to step 220 to the IP Location Server (IPLS) 145 for the subscriber. The request for status information of the user terminal 110 is transmitted.

The IPLS 145 checks the state information of the user terminal 110 in step 225 to confirm that the current state of the user terminal 110 is a dormant state, and then proceeds to step 230 and proceeds with the mobile communication service. An IP address request is sent to DNS 140 to know the IP address of the subscriber (ie, assigned to the user terminal).

In step 230, the DNS having received the IP address request from the IPLS 145 proceeds to step 310 to retrieve IP address information allocated to the user terminal 110.

If the inspection result of step 310 does not find the IP address assigned to the user terminal 110 (i.e., if the corresponding IP address is not found when searching using the subscriber's IMSI number), In step 315, the IP address for the user terminal is set to a predetermined number (e.g., "0. 0. 0", etc.), and then the set IP address information and the situation (i.e., the user terminal) are set. Process result information, including cause code information, which has been previously designated, is transmitted to IPLS 145.

In step 320, the IPLS 145 uses the processing result information received in step 315 to transmit the terminal information including the IP address information and cause code information (i.e., code information corresponding to the absence of the IP address) to the LMSC 150. To send.

Further, in addition to the case where the processing result information including the content that the IP address cannot be found from the DNS 140 is received, the processing result information is received from the DNS 140 for a predetermined time (for example, 1 minute, etc.). If not, the IPLS 145 transmits the reason code information (that is, the processing result reception waiting timeout information) corresponding to the situation to the LMSC 150 together with the IP address information set to a predetermined number.

FIG. 7A is a data flow diagram illustrating a method of changing a user terminal in an inactive state to an active state so that the data management system according to the present invention can transmit data to the user terminal by itself, and FIG. 7B is a flowchart of the present invention. FIG. 7C is a flow chart illustrating a method of registering simple IP address information allocated to a user terminal in a data management system, and FIG. 7C illustrates a mobile IP address assigned to a user terminal in a data management system according to the present invention. Data flow diagram showing a method of registering address) information.

In the present specification, unlike the case of mobile IP address information, a simple IP address is defined as meaning IP address information that is not guaranteed to be persistent according to the location of the subscriber.

When the user terminal 110 is in an inactive state, the state in which the user terminal 110 establishes only a session with the data management system 115 is compared with an active state. it means. In addition, the PDSN (Packet Data Serving Node) 130 and the PPP configuration are terminated, and the IP address is also deleted from the Domain Name Server (DNS) 140. Therefore, in order to transmit data from the data management system 115 to the user terminal 110, the following steps are required.

Referring to FIG. 7A, when there is a message to be transmitted to the mobile communication service subscriber in the long message entity (LME) 155, in step 210, the LME 155 transmits an LMS (LMS) to the long message service center (LMSC) 150. Long Message Service) Send a service request (ie, LMS message transfer request).

In step 215, the LMSC 150 checks the validity of the subscriber's International Mobile Subscriber Identity (IMSI). The request for status information of the user terminal 110 is transmitted.

The IPLS 145 checks the state information of the user terminal 110 at step 510 to confirm that the current state of the user terminal 110 is in an idle state, and then the user terminal 110 of the subscriber In order to know the IP address information after the conversion to the active state, the flow proceeds to step 515 in order to know the IP address of the mobile communication service subscriber (i.e., assigned to the user terminal) to the DNS 140 for the subscriber's IMSI. Send a pending request to register the number in the pending list.

DNS 140 registers the subscriber's IMSI number in the pending list in step 520, and proceeds to step 525 to transmit the registration result information to IPLS 145.

In operation 530, the IPLS 145 transmits the terminal information including the terminal state information (ie, inactive state) to the LMSC 150. Of course, in this case, as described above, the terminal information may include the subscriber's IMSI number.

The LMSC 150 recognizes that the current state of the user terminal 110 is in an idle state by using the terminal information received in step 530, and pending an IMSI number of the subscriber in step 535. list).

In operation 540, the IPLS 145 transmits the terminal to the Session Control and Mobility Management (SCMM) 125 to change the state of the user terminal 110 from an idle state to an active state capable of data transmission. The activation request information (which may include the subscriber's IMSI number, the current status information of the user terminal 110, etc.) is transmitted.

In addition, step 540 may further include the SCMM 125 transmits response information indicating that the terminal activation request information is normally received from the IPLS 145 to the IPLS 145.

In step 545, the SCMM 125 establishes a connection through the communication network between the user terminal and the data management system in response to the terminal activation request received in step 540.

As described above, since the idle state is a state in which only a session is established between the user terminal 110 and the data management system 115, a new connection should be established. In addition, a new PPP setting must be made between the user terminal 110 and the packet data serving node (PDSN) 130, and the IMSI and IP address of the user terminal 110 are also registered in the domain name server (DNS) 140. Should be.

Since the connection establishment step between the user terminal 110 and the data management system 115 is completed through step 545 in order to activate the user terminal 110, the step 550 of FIG. 7A is illustrated in FIGS. 7B and 7B. With reference to 7c will be described the process of setting up PPP between the user terminal 110 and the PDSN 130 and the process of registering the IMSI and IP address of the user terminal 110 in the Domain Name Server (DNS) 140 do.

7B illustrates a method of registering IP address information allocated to the user terminal in the data management system 115 when the IP address information allocated to the user terminal 110 is simple IP address information. .

Referring to FIG. 7B, in step 610, PPP configuration is performed between the user terminal 110 and the PDSN 130. In step 615, the PDSN 130 is allocated to the user terminal 110 during the PPP negotiation. The IP address information and the IMSI number of the subscriber are transmitted to the DNS 140.

In step 620, the DNS 140 registers the subscriber's IMSI number and IP address information assigned to the user terminal 110 received in step 615, and proceeds to step 625 to register the registered registration result with the PDSN 130. To send.

FIG. 7C shows the user in the data management system 115 when the IP address information assigned to the user terminal 110 is Mobile IP address information which ensures the persistence of the connection even by moving the location of the subscriber. A method of registering IP address information allocated to a terminal is shown.

Referring to FIG. 7C, PPP is established between the user terminal 110 and the PDSN 130 at step 655, and the PDSN 130 and the PDGN 135 are linked to the user terminal 110 in step 660. In the mobile IP registration operation performing step (ie, mobile IP registration attempt and response step), appropriate IP address information is allocated to the user terminal 110.

In step 670, the PDGN 135 transmits the IP address information assigned to the user terminal 110 and the IMSI number for the subscriber to the DNS 140 in the step of performing the mobile IP registration operation, and thus the IP address information and the IMSI number. Request registration for

In step 675, the DNS 140 registers the subscriber's IMSI number and IP address information allocated to the user terminal 110 received in step 670, and proceeds to step 680 to register the registered registration result with the PDGN 135. To send.

Referring back to FIG. 7A, at step 555, the DNS 140 receives the PDSN 130 or the PDGN 135 from the subscriber IMSI (see step 615 of FIG. 7B and step 670 of FIG. 7C) in advance through step 520 or the like. Check whether it exists in the registered pending list.

If the check result of step 555 indicates that the subscriber's IMSI number exists in the pending list, the flow proceeds to step 560 to include the subscriber's IMSI number and IP address information assigned to the user terminal 110 by IPLS 145. Transmits the search result information.

In step 565, the IPLS 145 receives the IMSI number of the subscriber received from the DNS 140 in step 560, IP address information assigned to the user terminal 110, and status information of the user terminal 110 confirmed in step 510. The terminal information including the transmits to the LMSC 150.

In operation 570, the LMSC 150 transmits the call notification information to the user terminal 110 through the communication network.

In operation 575, when the call request information is input from the subscriber, the user terminal 110 transmits the received call request information to the LMSC 150.

Thereafter, the LMSC 150 transmits the LMS message (ie, the long message) requested from the user terminal to the user terminal 110 in step 580.

8 is a data flowchart illustrating a processing method when the user terminal state information registered between the SCMM 125 and the IPLS 150 in the data management system according to the present invention is different.

Referring to FIG. 8 to describe a processing method in a case where user terminal state information registered between the SCMM 125 and the IPLS 145 is different, the same contents as those described above with reference to FIG. 7A are described in steps 210 to 540. Description of the description will be omitted.

In step 710, the SCMM 125 recognizes that the current state of the user terminal 110 is in an idle state by using the terminal activation request information received from the IPLS 145 in step 540, and actually the current user terminal. It is checked whether the state of 110 is an idle state.

If the state of the user terminal 110 is not an idle state (ie, an active state, an idle state, a suspended state, a canceled state, or an unregistered state) through the confirmation of step 710, the user terminal 110 The current status information of the and the cause (cause code) is transmitted to the IPLS (145).

The IPLS 145 receives the actual state information of the user terminal 110 from the SCMM 125 and repeatedly performs steps 510 to 540 to confirm it, or the user terminal 110 received from the SCMM 125. Update can be registered with status information.

FIG. 9 is a data flow diagram illustrating a method of transmitting data to a user terminal in which a data management system according to the present invention is in a self-parking state.

When the user terminal 110 is in a parked state, both the session and the connection are terminated between the user terminal 110 and the data management system 115 when compared to the active state. In this state, the PPP setting between the user terminal 110 and the PDSN 130 is also terminated, and the IMSI and IP address of the user terminal 110 are also deleted in the DNS 140. However, the parking state is a state in which the user terminal 110 is registered in the IPLS 145 and is compared with a non-state.

If there is a message to be sent to the mobile communication service subscriber in the long message entity (LME) 155, the LME 155 transmits an LMS service request (ie, an LMS message transmission request) to the LMSC 150 at step 210. .

In step 215, the LMSC 150 checks the validity of the subscriber's IMSI number. If the IMSI number is valid, the LMSC 150 proceeds to step 220 and transmits a status information request of the user terminal 110 of the subscriber to the IPLS 145. do.

The IPLS 145 confirms that the state of the user terminal 110 is a parking state in step 810, and proceeds to step 820, and the IMSI number of the subscriber and the current state information of the user terminal (ie, the termination state). The terminal information including) is transmitted to the LMSC 150.

In step 830, the LMSC 150 recognizes that the state of the user terminal 110 cannot provide the LMS message transmission service as a parking state, and uses the Short Message Service (SMS) service. 110) to send an SMS message (for example, "Hong Gil-dong has received an LMS message. Please visit http://www.lms-confirm.co.kr").

The data flow diagram shown in FIG. 9 may be equally applicable to the case where the user terminal 110 is in an inactive state as well as the case where the state of the user terminal 110 is in a parked state. In addition, the same may be applied to the case where the user terminal 110 is a terminal (for example, a terminal not registered) that is not suitable for using a data-only network.

However, when the user terminal 110 is an inactive state or a terminal not suitable for using a data-only network, in step 810, the IPLS 145 is inactive state as state information of the user terminal 110, respectively. The only difference is that it is recognized as a non-state.

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, the present invention manages the state and IP address of the user terminal connected to the data-dedicated network in the mobile communication service system, thereby converting the data into a state capable of receiving data regardless of the current state of the user terminal, and thus is self-contained in the mobile communication system. This enables the transmission of necessary data to the user terminal.

The present invention also provides a mobile communication service subscriber which simultaneously accesses a voice network and a data network even when applying a method of transmitting data to a terminal using a data service using an IP protocol in a state in which a voice network and a data network are separated. In addition, the optimal data service can be performed by identifying the location or state of the user terminal of the subscriber connected only to the data network.

In addition, when the data is transmitted to the mobile communication service subscriber between the mobile communication service subscribers or in the mobile communication service system, the present invention may include multimedia information in the data.

In addition, the present invention is capable of receiving data in the form of a voice incoming currently performed in an IP communication network composed of packets as well as wireless LAN as a data-only network without a circuit concept.
