And INTERNET) to provide circuit switching services to mobile subscribers.

The HLR 114 is a home location register that manages mobility (location) information and various additional service information for a mobile subscriber, and includes a subscriber telephone number (MIN) and a terminal unique number (ESN). : Stores and manages basic information such as Electric Serial Number), call processing routing information (location information), subscriber authority, and additional service information such as caller ID display and call forwarding.

Regarding the terminal location registration through the HLR 114 described above, since it is a conventional technique that is already known and implemented in various ways before this application, a detailed description thereof will be omitted.

The AUC 115 stores subscriber authentication information and corresponds to a subscriber telephone number (MIN: Mobile Identification Number) and a terminal unique number (ESN: Electric Serial Number) included in the subscriber authentication request from the HLR 114. The subscriber is searched with reference to the subscriber authentication information and the subscriber authentication is processed according to the search result.

Regarding subscriber authentication through the AUC 115, since it is a conventional technique that is already known and implemented in various ways before this application, a detailed description thereof will be omitted.

The IWF 116 is an Inter-Working Fuction for connecting between a mobile communication network and the Internet network, and serves as a gateway for data communication between the mobile communication network and the Internet network.

Meanwhile, the HDR network module 120 includes an HDR access point 121, a BTC 122, a PCF 123, a PSDN 124, an HA 125, and an AAA 126.

The HDR access point 121 is an access point constituting a direct wireless path with the hybrid terminal 200 for high speed data communication, and controls data transmission and reception with the hybrid terminal 200.

The HDR access point 121 is installed separately from the IS-95 / 1x BTS 111 of the IS-95 / 1x network module 110 described above or integrally embedded in the IS-95 / 1x BTS 111. Can be installed.

The AAA 126 is linked to the PSDN 124 to perform authentication, authorization, and accounting for a mobile IP service.

Authentication, authorization, and accounting technology for the mobile IP service through the AAA 126 is a conventional technology that is variously known and implemented before this application, and thus will be described in detail. Will be omitted.

Upon initial power-up of the hybrid terminal 200 in the mobile communication system 100 for the high speed data communication, the mobile communication system 100 performs terminal location registration through the HLR 114 and the AUC 115. In the process of subscriber authentication, the user information is incorrectly input and the registered terminal or the duplicated terminal is not authenticated and the mobile communication system sends a lock order to the corresponding hybrid terminal 200. Will be sent.

In the related art, the hybrid terminal 200 that receives the lock order from the mobile communication system 100 is powered by the hybrid terminal 200 through software processing executed by a mobile switching modem (MSM). The voice call is restricted by preventing the keypad operation of the hybrid terminal to prevent further voice communication access unless re-authorization.

That is, in the conventional hybrid terminal, the voice communication connection through the IS-95 / 1x network module 110 is restricted when the terminal location registration or subscriber authentication fails, but the data through the HDR network module 120 that processes high-speed data communication is limited. Since the communication connection is not restricted, the mobile IP authentication through the HA 125 and the authentication for the mobile IP service through the AAA 126 are unnecessary when a data communication connection is requested using a terminal whose terminal location registration or subscriber authentication fails. Authentication procedure was performed.

However, when the terminal location registration through the HLR 114 or subscriber authentication fails through the AUC 115, mobile IP authentication through the HA 125 and authentication for a mobile IP service through the AAA 126 ( Authentication must also fail, of course, when requesting a data communication connection using a terminal whose terminal location registration or subscriber authentication has failed, authentication for mobile IP service through the HA 125 and authentication for a mobile IP service through the AAA 126 (Authentication). Performing a procedure is an unnecessary procedure.

Therefore, the performance thereof causes the power consumption of the hybrid terminal and causes a problem of imposing unnecessary load on the base station controller (BTC) of the mobile communication system.

Accordingly, the present inventors simultaneously limit the terminal communication or the subscriber communication by limiting the voice communication connection through the IS-95 / 1x network module and the data communication connection through the HDR network module that handles high-speed data communication when the terminal location registration or subscriber authentication fails. In principle, the data communication connection through the failed terminal is blocked, so that the researcher can study the communication connection limiting system and method of the hybrid terminal which can prevent unnecessary power consumption of the hybrid terminal and unnecessary load of the base station controller (BTC). It became.

The present invention has been invented in view of the above, so that in case of terminal location registration or subscriber authentication failure, simultaneously limiting the data communication connection through the HDR network module which handles the high speed data communication and the voice communication connection through the IS-95 / 1x network module It is an object of the present invention to provide a system and method for limiting communication connection of a hybrid terminal.

According to an aspect of the present invention for achieving the above object, the communication access restriction system and method of the hybrid terminal according to the present invention according to the lock order from the mobile communication system according to the subscriber authentication or location registration failure (Lock Order) It blocks the voice communication attempt through the IS-95 / 1x BTS, and simultaneously blocks the data communication attempt through the HDR access point.

Therefore, when the terminal location registration or subscriber authentication fails, the data communication through the terminal where the terminal location registration or subscriber authentication fails is restricted by simultaneously restricting the voice communication connection through the IS-95 / 1x network and the data communication connection through the HDR network that handles the high-speed data communication. By blocking the communication connection in principle, unnecessary power consumption of the hybrid terminal and unnecessary load of the base station controller (BTC) can be prevented.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce the present invention.

2 is a schematic diagram of a communication connection restriction system of a hybrid terminal according to the present invention.

The communication access restriction system 300 of the hybrid terminal according to the present invention exists in the form of software executable in the hybrid terminal 200 supporting the IS-95 / HDR dual mode, and thus the mobile communication according to the subscriber authentication or location registration failure. Blocks voice communication attempts through the IS-95 / 1x BTS according to the lock order from the system, and simultaneously blocks data communication attempts through the HDR access point. By simultaneously limiting the voice communication connection through the -95 / 1x network and the data communication connection through the HDR network that handles high-speed data communication, unnecessary power consumption of the hybrid terminal and unnecessary load generation of the base station controller (BTC) can be prevented. I would have to.

With reference to Figure 3 looks at the specific configuration of the communication access restriction system 300 of the hybrid terminal according to the present invention.

3 is a block diagram of one embodiment of a communication connection restriction system of a hybrid terminal according to the present invention.

As shown in the figure, the communication connection limiting system 300 of the hybrid terminal according to the present invention includes a block command receiving unit 310, a voice communication blocking unit 320, and a data communication blocking unit 330.

When the user turns on the hybrid terminal 200, the hybrid terminal 200 is synchronized to the IS-95 / 1x BTS 111 having the strongest electric field strength to perform the terminal location registration and subscriber authentication procedure. do.

First, the hybrid terminal 200 synchronizes the terminal location registration and subscriber authentication request information including its subscriber number (MIN: Mobile Identification Number) and terminal unique number (ESN: Electric Serial Number). Send to the BTS 111.

The terminal location registration and subscriber authentication request information is transmitted to the MSC 113 via the BTC 112, the MSC 113 requests the terminal location registration to the HLR 114, and the subscriber authentication to the AUC 115 request.

If the subscriber authentication and the terminal location registration succeed as a result of the terminal location registration through the HLR 114 and the subscriber authentication procedure through the AUC 115, the MSC 113 receives the BTC 112 and the IS-95 / 1x. The authentication success message is transmitted to the hybrid terminal 200 via the BTS 111 so that the subscriber can use the desired service. When the hybrid terminal 200 receives the authentication success message, the hybrid terminal 200 enters a service standby state, and thus, the hybrid terminal 200 may use a service provided by the mobile communication service provider according to a user's operation.

If the subscriber authentication or the terminal location registration fails as a result of the terminal location registration through the HLR 114 and the subscriber authentication procedure through the AUC 115, the MSC 113 determines the BTC 112 and the IS-95. The authentication failure message is transmitted to the hybrid terminal 200 via the / 1x BTS 111.

The authentication failure message includes a lock order to block voice communication attempts through the IS-95 / 1x BTS and at the same time to block data communication attempts through the HDR access point.

Then, the blocking command receiving unit 310 receives a lock order generated by a subscriber authentication or location registration failure from the mobile communication system 100.

On the other hand, the voice communication blocker 320 limits the user interface input of the hybrid terminal 200 when receiving a block order (Lock Order) by the block command receiving unit 310 voice communication through the IS-95 / 1x BTS Block the attempt.

That is, when a lock order is received by the blocking command receiving unit 310, the communication connection limiting system 300 of the hybrid terminal according to the present invention is IS-95 / through the voice communication blocking unit 320. It attempts to block the voice communication attempt through the 1x BTS. At this time, the voice communication attempt is blocked by preventing the operation of the keys related to the voice communication among the keypads of the hybrid terminal 200.

Meanwhile, the data communication blocking unit 330 sets the data call origination of the HDR task stage that manages the HDR connection to fail when the blocking command receiving unit 310 receives the lock order to access the HDR. Blocks data communication attempts through points.

That is, when a lock order is received by the blocking command receiving unit 310, the communication access restriction system 300 of the hybrid terminal according to the present invention uses an HDR access point through the data communication blocking unit 330. In this case, the data communication attempt is blocked, and the HDR task (Task) is set by setting Data Call Origination of the HDR task, which is software that is executed under the control of the operating system of the hybrid terminal 200 and manages the HDR connection, to Fail. ) Attempts to communicate data through the HDR access point with reference to the Fail setting value of the Data Call Origination field during the HDR access process.

The HDR task processes a data communication connection through the HDR access point when the Data Call Origination field value is Success, and prevents data communication attempt through the HDR access point when Fail.

Therefore, when the communication access restriction system 300 of the hybrid terminal according to the present invention receives a lock order due to a subscriber authentication or location registration failure from the mobile communication system 100 through the blocking command receiving unit 310, Through the voice communication blocker 320, the user interface input of the hybrid terminal 200 is restricted to block the voice communication attempt through the IS-95 / 1x BTS, and at the same time, through the data communication blocker 330. By setting Data Call Origination of Failed HDR task stage to Fail to block data communication attempt through HDR access point, it is in principle unnecessary to block data communication connection through terminal where terminal location registration or subscriber authentication failed. It prevents power consumption of the hybrid terminal and generation of unnecessary load of the base station controller (BTC).

The communication connection restriction method of the hybrid terminal according to the present invention having the above configuration will be described in detail with reference to FIG. 4.

4 is a flowchart illustrating a communication connection restriction method of a hybrid terminal according to the present invention.

First, upon initial power-up of the hybrid terminal in the authentication and registration request step (S110), the hybrid terminal has its subscriber number (MIN: Mobile Identification Number) and terminal unique number (ESN: Electric) with a synchronized IS-95 / 1x BTS. Requesting subscriber authentication and location registration to the mobile communication system by transmitting terminal location registration and subscriber authentication request information including Serial Number).

Accordingly, the MSC of the mobile communication system performs the terminal location registration procedure through the linked HLR, and performs the subscriber authentication procedure through the AUC, and the result is transmitted through the BTC and the IS-95 / 1x BTS. Notify by.

At this time, if the authentication fails, a lock order that blocks the voice communication attempt through the IS-95 / 1x BTS and simultaneously blocks the data communication attempt through the HDR access point is included in the authentication failure message. From the communication system to the hybrid terminal.

Then, in the step S120 of receiving a block command, a lock command from the mobile communication system is received.

Thereafter, through the voice communication blocking step (S130), the user interface input of the hybrid terminal is restricted to block the voice communication attempt through the IS-95 / 1x BTS, and the HDR communication is performed through the data communication blocking step (S140). By setting Data Call Origination of the HDR task stage to Fail to block data communication attempts through the HDR access point.

At this time, the voice communication attempt blocking process by the voice communication blocking step (S130) and the data communication attempt blocking process by the data communication blocking step (S140) are performed independently of each other. The step may be performed first.

Therefore, when the hybrid terminal receives a lock order from subscriber authentication or location registration failure from the mobile communication system, the voice communication attempt through the IS-95 / 1x BTS and the data communication attempt through the HDR access point are executed in software. The power consumption of the hybrid terminal and the base station controller (BTC) are blocked by in principle preventing unnecessary access to the mobile communication system through the terminal whose terminal location registration or subscriber authentication fails, unless the power of the terminal whose terminal location registration or subscriber authentication has failed is re-authorized. This prevents unnecessary load of).

By doing so, the communication connection limiting system and method of the hybrid terminal according to the present invention can achieve the object of the present invention described above.

As described above, the system and method for limiting communication access of a hybrid terminal according to the present invention is an IS-95 / 1x BTS at the hybrid terminal when receiving a lock order due to a subscriber authentication or location registration failure from a mobile communication system. In principle, unnecessary access to the mobile communication system through the hybrid terminal is blocked unless the power of the terminal that fails to register the terminal or authenticates the subscriber is re-authorized by software blocking the attempt to communicate with the user and the data through the HDR access point. By doing so, there is a useful effect of preventing power consumption of the hybrid terminal and generation of unnecessary load of the base station controller (BTC).

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that various modifications may be made therein without departing from the scope of the invention, which is covered by the following claims.
