BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a femtocell terminal, a femtocell terminal, and a femtocell terminal,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a system and method for blocking access to a femtocell terminal through a third party wired network.

2. Description of the Related Art In recent years, various types of high-speed data service systems such as High Speed Downlink Packet Access (HSDPA) and Mobile WIMAX have emerged as wireless communication services, and they have been developed as wireless data services. However, a system providing such a high-speed data service has a channel capacity of only a few megabits per second (Mbps). As the channel capacity is divided and used by hundreds of users existing in a base station (BS) It is only a few hundred Kbps. Therefore, it is not satisfying users who experienced several tens of Mbps speed of wired and wireless LAN.

An attempt has been made to provide a transmission capacity of several megabits per second (Mbps) per subscriber in a mobile communication system by installing it in a room such as a home or an office and using a small number of users. In this regard, recently, a femtocell which is supervised by a small base station has been proposed. Here, the femtocell means a femto of 10-15 and a combination of cells meaning a service area unit managed by one base station in mobile communication, which means a service area smaller than the existing mobile communication service area, and a femto base station is called a DSL Digital subscriber line) modem to allow the femtocell terminal to freely use wired / wireless communication.

In this way, unlike a macro base station, a femtocell passes through a general home subscriber network, and when a wired network of a subscriber is changed due to a reason such as a moving of a customer, a carrier of a wired network and a mobile communication network, In this case, it is necessary to block the connection through the wired network of other companies because there are issues such as charging when passing the third party's wired network. For this purpose, SON (Self Organizing Network) server has been blocked based on Internet Protocol (IP) coming from femtocell. However, there is a problem that separate SON server is needed for this. In addition, in the past, when a SON server is connected through a wired network of a third party, there is a problem in that there are many VOCs (Voice of Customers) for the service by blocking the service without knowing the customer using the femtocell terminal.

A problem to be solved by the present invention is to provide a system and method for blocking an access to a femtocell that does not use a SON server by blocking access of a user terminal through a wired network of a third party.

Here, if the DNS (Domain Name Server) allocated to the femtocell terminal is not the DNS of the wireless service provider, or the IP allocation scheme for the femtocell terminal is not a fixed IP allocation scheme, The femtocell terminal determines that the femtocell terminal accesses the wireless service through a wired network of a service provider different from the wireless service provider, and transmits a third party DNS alarm to the home base station management server.

If the femtocell terminal is not the IP of the wireless service provider, the femtocell terminal accesses the wireless service through a wired network of a service provider different from the wireless service provider, And transmits a third party service alarm to the home base station management server. If the IP allocated to the femtocell terminal is a private IP, the public IP corresponding to the private IP is obtained.

Also, the service provider of the public IP assigned to the femtocell terminal is confirmed through a Whois query.

In addition, when the third-party DNS alarm or the third-party service alarm is received from the femto base station, the home-base station management server transmits the service alarm to the wireless service provider through a wired network of a service provider different from the wireless service provider, And notifies the femtocell terminal of the service interruption through a text message or a redirection transmission.

In addition, the text message is a CMAS (Commercial Mobile Alert System) CMAS message or a SMS (Short Message Service) text message.

Also, the access blocking system may be connected to the femto base station through the femto gateway, and when the femtocell terminal accesses a web page through the femto base station, The femtocell terminal further comprises a redirection gateway for displaying to the femtocell terminal a warning web page that notifies the femtocell terminal that the service is blocked due to connection of the wireless service through a wired network of a service provider different from the wireless service provider.

In addition, the femto base station performs service shutdown for the femtocell terminal after a predetermined time after transmission of the third-party DNS alarm or the service alarm of the third party, and the home- A text message or a redirection transmission for notifying service termination to the femtocell terminal is repeatedly performed a predetermined number of times.

In addition, the femto base station checks quality of service indicator (QCI) at the time of the redirection transmission, and does not block the femtocell terminal if the service of the femtocell terminal is a voice call service through the QCI .

The femto base station may further include: an access information acquisition unit that acquires access information for the femtocell terminal from the home base station management server; A public IP acquisition unit for acquiring a public IP corresponding to the private IP when the IP allocated to the femtocell terminal identified through the access information is a private IP; Whether the DNS allocated to the femtocell terminal identified by the access information is the DNS of the wireless service provider, whether the IP allocation scheme for the femtocell terminal is a fixed IP allocation scheme, A determination unit for determining whether the IP is an IP of a wireless service provider; When the determination unit determines that the femtocell terminal is not the DNS of the wireless service provider or the IP allocation method for the femtocell terminal is not the fixed IP allocation method, If the IP address assigned to the femtocell terminal is not the IP of the wireless service provider, the femtocell terminal transmits the DNS alarm of the third party to the home base station management server, An alarm transmission unit for determining that the wireless service is connected to the wireless service through a wired network of a service provider different from the service provider of the wireless service and transmitting a third party service alarm to the home base station management server; And a service blocking unit for blocking a service for the femtocell terminal.

According to another aspect of the present invention,

A femtocell terminal connected wirelessly to a femto base station covering a femtocell is connected to a wired network through a femto gateway connected to the femto base station, Receiving a service; Determining whether the femtocell terminal is connected to the wireless service through a wired network of a service provider different from the service provider of the wireless service; And when the femtocell terminal determines that the femtocell terminal has accessed the wireless service through a wired network of a service provider different from the wireless service provider, And blocking the service for the femtocell terminal after notifying the service interception due to the connection of the service.

Here, the step of determining whether or not the wireless service is connected may include determining whether the DNS allocated to the femtocell terminal is the DNS of the wireless service provider or whether the IP allocation method for the femtocell terminal is a fixed IP allocation method Determining whether or not it is possible; If the DNS allocated to the femtocell terminal is not the DNS of the wireless service provider, or the IP allocation scheme for the femtocell terminal is not a fixed IP allocation scheme, the femtocell terminal may be a service provider If the DNS allocated to the femtocell terminal is the DNS of the wireless service provider and the IP allocation method for the femtocell terminal is the fixed IP allocation method, Determining whether the assigned public IP is an IP of the wireless service provider; And determining that the femtocell terminal is connected to the wireless service through a wired network of a service provider different from the service provider of the wireless service when the public IP allocated to the femtocell terminal is not the IP of the wireless service provider .

The blocking of the service for the femtocell terminal may include notifying the femtocell terminal of a service interruption due to the connection of the wireless service through a wired network of a service provider different from the wireless service provider through a text message or a redirection transmission ; And blocking the service for the femtocell terminal.

The femtocell terminal may notify the femtocell terminal of the fact that the femtocell terminal is shut down due to connection of the wireless service through a wired network of a service provider different from the service provider of the wireless service, And displays it to the terminal.

Also, in the step of notifying through the redirection transmission, if the service of the femtocell terminal is a voice call service through QCI, the redirection transmission and the service blocking to the femtocell terminal are not performed.

According to another aspect of the present invention,

A femto base station that covers a femtocell that provides a wireless service to a femtocell terminal; and a femto base station that manages the femtocell base station The home base station management server and the femtocell terminal perform signal transmission with a wired network connected to a core network that provides the wireless service, and the memory is configured to store a set of codes, Acquiring access information for the femtocell terminal from a home base station management server; Acquiring a service provider of an IP allocated to the femtocell terminal through the communicator; Determining whether the DNS allocated to the femtocell terminal is a service provider of the wireless service or whether the IP allocation scheme for the femtocell terminal is a fixed IP allocation scheme; Determining whether an IP allocated to the femtocell terminal is an IP of a wireless service provider; And controlling the processor to perform an operation of performing a service interception to the femtocell terminal.

Here, the processor further performs an operation of acquiring a public IP corresponding to the private IP allocated to the femtocell terminal through the communicator.

If the DNS allocated to the femtocell terminal is not the DNS of the wireless service provider, or the IP allocation scheme for the femtocell terminal is not a fixed IP allocation scheme, When the IP is not the IP of the wireless service provider, the home base station management server notifies the home base station management server via the communication unit that the femtocell terminal is in charge of the wireless communication through the wired network of a service provider different from the wireless service provider, Further instructing the femtocell terminal to notify the femtocell terminal through a text message or a redirect transmission that the service is blocked due to the connection of the service.

Also, the terms " part, "" module," and " module ", etc. in the specification mean a unit for processing at least one function or operation and may be implemented by hardware or software or a combination of hardware and software have.

Hereinafter, another death prevention system for blocking a connection through a third-party wired network of a femtocell terminal according to an embodiment of the present invention will be described with reference to the drawings.

1 is a schematic block diagram of an access blocking system through a non-wired network according to an embodiment of the present invention.

1, the access blocking system 10 according to the embodiment of the present invention includes a femto base station 100, a femto gateway 200, a home eNodeB management system (HeMS) 300, And a redirection gateway 400.

The femto base station 100 is a small base station that covers a femtocell, and is installed in various areas to form a plurality of femtocells. This femto base station 100 is a base station installed by a user and provides a wireless connection to the user terminal 500. [ That is, the femto base station 100 transmits and receives signals to and from the user terminal 500 through the wireless channel, and allocates the radio resources to the user terminal 500. Such a small base station 100 may also be referred to as a Home eNodeB (HeNB).

The femto gateway 200 provides a connection to the wired network 600, for example, the Internet or the core network 700, for example, an EPC (Evolved Packet Core) to the user terminal 500 connected to the femto base station 100 . Here, the EPC includes a Mobility Management Entity (MME) for performing call processing related operations such as session management and mobility management, and a base station for transmitting data packets and serving as a reference point for handover between eNBs or between an LTE network and another 3GPP network (PDN) gateway (P-GW) that provides connectivity between the serving gateway (S-GW) and the UE and the external data network and serves as a reference point for handover between the LTE network and the non-3GPP network .

The HeMS 300 is a management server connected to the femto gateway 200 to independently process information reported by a plurality of femto base stations 100. That is, the femto base stations 100 are collectively managed through a server called HeMS 300.

The redirection gateway 400 is a device for displaying a web page indicating that a user terminal 500 connected through an unauthorized terminal, that is, a third-party wired network, is connected through a third-party wired network when accessing a web page.

The femto base station 100 according to an exemplary embodiment of the present invention can access the femto base station 100 via the DNS (Domain Name Server) or IP (Internet Protocol) assigned to the user terminal 500 connected to the wired network 600 through the femto gateway 100, Of the wired network 600 is used. Here, the femto base station 100 may determine whether the IP allocation for the user terminal 500 is a fixed IP allocation. In addition, when the IP allocated to the user terminal 500 is a private IP, the femto base station 100 may acquire and use a corresponding public IP.

The femto base station 100 determines that the DNS allocated to the user terminal 500 is a DNS of a third party when the DNS assigned to the user terminal 500 is not its own DNS or the IP allocation for the user terminal 500 is not a fixed IP allocation but a dynamic IP allocation 200 to the HeMS 300. [0033] Also, the femto base station 100 may generate an alarm notifying the HeMS 300 through the femto gateway 200 that the public IP assigned to the user terminal 500 is a third party service when the public IP is not its own IP. At this time, the base station 100 can confirm whether the public IP assigned to the user terminal 500 is its IP through a Whois query. Here, the Whois query is a service that provides information on the communication network of the Internet, and can know the service provider from the public IP.

Since it is natural that the femto BS 100 and the HeMS 300 transmit messages and data through the femto gateway 200, the femto gateway 200 will be omitted for the sake of convenience in the following description Even if the femto base station 100 and the HeMS 300 transmit the message or data directly, it means that the femto gateway 200 is omitted from the relaying function between the femto base station 100 and the HeMS 300.

When the user terminal 500 receives an alarm from the femto base station 100 indicating that the user terminal 500 is a third party DNS by using the third-party wire network 600 or an alarm indicating that the third party service is a short message service (SMS) And notifies the user terminal 500 through a character service such as a CMAS (Commercial Mobile Alert System), thereby notifying the user that the service will be blocked due to the use of the wired network 600 of the third party. Here, the CMAS is a commercial mobile warning system, which is a system for transmitting a text message to a citizen in a home country by using a mobile phone when an emergency occurs.

Optionally, the HeMS 300 instructs the femto base station 100 to redirect to the redirection gateway 400 in consideration of the case where the user terminal 500 uses the web service, and the femto base station 100 transmits the redirection to the user terminal 500 to the user terminal 500 through the redirection gateway 400. The redirection gateway 400 transmits a redirection message to the user terminal 500 via the redirection gateway 400. [

Meanwhile, the femto base station 100 confirms the Quality of Service Class Indicator (QCI) when the redirection of the alert page is transmitted. This QCI confirmation is for confirming whether the service of the user terminal 500 is a VoLTE (voice over LTE) service or a web page service for performing a voice call using an LTE (Long Term Evolution) network. Even if the user terminal 500 uses the wired network 600 of the other company through the QCI confirmation, the telephone can be used even if the data use is cut off through the redirection transmission.

The HeMS 300 notifies the user terminal 500 of the service interruption through the transmission of a text message such as SMS or CMAS or the redirection of the warning page and then transmits the service for the user terminal 500 to the base station 100 .

Optionally, the HeMS 300 notifies the user terminal 500 of the service interruption through transmission of text messages such as SMS, CMAS, or redirection of the alert page, and then performs service interruption after a certain period of time. In addition, the HeMS 300 can transmit a text message such as SMS, CMAS, or the like to the user terminal 500 a certain number of times, or transmit a redirection of a warning page, thereby notifying the user terminal 500 of a certain number of service interruptions.

Meanwhile, if the DNS allocated to the user terminal 500 is its own DNS and the IP allocated to the user terminal 500 is an IP assigned by the fixed IP allocation and is its own IP, And provides the normal service to the user terminal 500. [

As described above, according to the embodiment of the present invention, since the femtocell does not need to use the SON server by blocking the connection of the user terminal 500 through the wired network 600 of the third party, the cost can be reduced, The VOC may be reduced by notifying the user through a text message such as SMS or CMAS or a redirection of the warning page by notifying the user immediately.

Hereinafter, the femto base station 100 will be described in detail.

FIG. 2 is a specific configuration block diagram of the femto base station 100 shown in FIG.

2, the femto base station 100 includes communication units 110 and 120, a signal processing unit 130, a connection information acquisition unit 140, a public IP acquisition unit 150, a determination unit 160, A transmission unit 170 and a service blocking unit 180. 2, description of the general configuration and operations of the femto base station 100 that are not related to the features of the present invention is omitted for convenience of description. In addition, since the femto base station 100 shown in FIG. 2 is only an embodiment of the present invention, the present invention is not limited to FIG. 2 and may be configured differently from FIG. 2 according to various embodiments of the present invention. It is possible.

The communication unit 110 performs signal transmission with the user terminal 500.

The communication unit 120 performs signal transmission with the femto gateway 200.

The signal processing unit 130 performs processing on signals transmitted between the user terminal 500 connected through the communication unit 110 and the femto gateway 200 connected through the communication unit 120.

The access information obtaining unit 140 obtains the access information for the user terminal 500 from the HeMS 300. [ The access information includes information such as DNS and IP allocated to the user terminal 500, presence / absence of fixed IP allocation, and the like.

The public IP obtaining unit 150 obtains a public IP corresponding to the private IP. At this time, the public IP corresponding to the private IP can be obtained from the HeMS 300 or the core network 800. For example, public IP can be obtained through the source address of a packet received during packet communication with the HeMS 300 or the core network 800.

The determination unit 160 determines whether the IP allocated to the user terminal 500 acquired by the connection information acquisition unit 140 is a private IP. If the private IP is a private IP, Obtain public IP.

The determining unit 160 determines whether the DNS assigned to the user terminal 500 acquired by the connection information obtaining unit 140 is the DNS of the user. If the DNS is not the DNS of the user, And notifies the service blocking unit 180 of the determination result indicating that the user terminal 500 is an abnormal service connected through the wired network 600 of the third party. The femto base station 100 knows its DNS in advance and sends it to the user terminal 500 acquired in the connection information acquisition unit 140 It will be appreciated that the assigned DNS can determine if it is its DNS.

In addition, the determination unit 160 determines whether it is a fixed IP allocation through access information for the user terminal 500 acquired by the connection information acquisition unit 140, and if it is not a fixed IP allocation, Notifies the alarm transmitting unit 170 and informs the service blocking unit 180 of the determination result indicating that the user terminal 500 is an abnormal service connected through the wired network 600 of the other company.

The determination unit 160 determines whether the IP allocated to the user terminal 500 is its own IP. If the IP is not its own IP, the determination unit 160 informs the alarm transmission unit 170 of this fact, 500 notifies the service blocking unit 180 of the determination result indicating that it is an abnormal service connected through the wired network 600 of the other company. At this time, it is possible to judge whether or not the IP of the company is using the Whois query.

If the DNS assigned to the user terminal 500 is the DNS of the user terminal 500 and the IP is the public IP and the IP is the IP of the user terminal 500, the determination unit 160 determines that the user terminal 500 is connected to its wired network 600 And notifies the service blocking unit 180 of the determination result indicating that the service is the normal service accessed through the service blocking unit 180.

The alarm transmitting unit 170 transmits an alarm message to the HeMS 300 requesting notification of service interruption to the user terminal 500 when the determination unit 160 receives the DNS or third party service of the third party.

The service interception unit 180 controls the signal processing unit 130 when the determination result received from the determination unit 160 indicates an abnormal service and transmits the result to the user terminal 500 and the femto gateway 200 through the communication units 110 and 120. [ Thereby blocking the service for the user terminal 500 by blocking signals transmitted between the wired network 600 and the wired network 600.

In addition, the service interception unit 180 does not perform any processing when the determination result received from the determination unit 160 indicates a normal service. Accordingly, the signal processing unit 130 continues the signal transmission process between the user terminal 500 and the wired network 600 through the communication units 110 and 120 so that the service for the user terminal 500 is continued.

Hereinafter, a method of blocking a connection through a third party wired network of a femtocell terminal according to an embodiment of the present invention will be described with reference to the drawings.

3 is a schematic flowchart of a connection blocking method through a non-wired network according to an embodiment of the present invention. The connection blocking method through the non-wired network according to FIG. 3 corresponds to the method performed by the femto base station 100.

3, when the user terminal 500 accesses the wired network 600 through the femto base station 100 and the femto gateway 200 (S100), the femto base station 100 transmits the user terminal 500 from the HeMS 300 500) (S110).

Thereafter, it is determined whether the IP allocated to the user terminal 500 is the private IP through the connection information for the user terminal 500 (S120).

If the IP allocated to the user terminal 500 is not a private IP, a public IP corresponding to the private IP is obtained (S130).

Thereafter, it is determined whether the IP allocation for the user terminal 500 is a fixed IP allocation, based on whether the DNS assigned to the user terminal 500 is its own DNS or access information for the user terminal 500 (S140).

If the DNS allocated to the user terminal 500 is not its own DNS or the IP allocation for the user terminal 500 is not a fixed IP allocation, the femto base station 100 transmits an alarm notifying the fact that it is a third party DNS, (S150).

Thereafter, the service for the user terminal 500 is blocked (S160).

Meanwhile, if the DNS assigned to the user terminal 500 is the DNS of the user terminal 500 and the IP allocation of the user terminal 500 is the static IP allocation, it is determined whether the IP allocated to the user terminal 500 is its own IP ).

If the IP address allocated to the user terminal 500 is not the IP address of the user terminal 500, an alarm is transmitted to the HeMS 300 indicating that the IP address is a third party service (S180).

Thereafter, the service for the user terminal 500 is blocked (S190).

On the other hand, if the IP allocated to the user terminal 500 is its own IP, the normal service is provided to the user terminal 500 (S200). The provision of such a normal service is one in which the currently connected user terminal 500 does not perform service interception so that it can continue to receive service. That is, it means that the femto base station 100 continuously provides the service for the user terminal 500.

Alternatively, the blocking of the service in step S160 may be performed after a predetermined time after the transmission of the third-party DNS notification in step S150.

Alternatively, the service interruption in step S190 may be performed after a certain time after the transmission of the third-party service notification in step S180.

Next, a connection blocking method through a non-wired network according to another embodiment of the present invention will be described.

4 is a schematic flowchart of a connection blocking method through a third party wired network according to another embodiment of the present invention. In Fig. 4, the same method steps as those in Fig. 3 are described using the same reference numerals. Here, the method steps according to FIG. 4 are performed by the femto gateway 200.

4, when the user terminal 500 accesses the wired network 600 through the femto access point 100 and the femto access point 200 (S100), the femto access point 100 transmits the user terminal 500 from the HeMS 300 500) (S110).

Then, it is judged whether or not the service interruption option is set in the acquired connection information (S115).

If the service blocking option is set in the obtained access information, the femto base station 100 informs the redirection gateway 400 that the user terminal 500 redirects the warning page about service blocking due to the use of the third party wired network 600 (S116).

Thereafter, the service for the user terminal 500 is blocked (S117).

On the other hand, if the service interception option is not set in the acquired connection information, the process continues from step S120 described in FIG. 3. Since the steps of FIG. 3 have been described with reference to FIG. 3, description thereof will be omitted.

Alternatively, the service interruption in the step S117 may be performed after a certain time after the redirection transmission instruction in the step S116.

Next, a connection blocking method through a non-wired network according to another embodiment of the present invention will be described.

FIG. 5 is a schematic flowchart of a connection blocking method through a non-wired network according to another embodiment of the present invention. The method steps according to FIG. 5 are performed by HeMS 300.

First, the HeMS 300 receives an alarm from the femto base station 100 indicating that it is a third-party DNS or an alarm indicating that the service is a third-party service (S300). That is, it means that the user terminal 500 is connected through the third-party wired network 500 and receives an alarm that the service termination to the user terminal 500 is to be performed. Thus, the later steps will correspond to the steps for notifying the user terminal 500 of the service interruption.

Thereafter, the HeMS 300 determines whether the character transmission is set in the manner of notifying the user terminal 500 of the service interruption (S310). It will be readily appreciated by those of ordinary skill in the art that such schemes are preset by the user or operator with the user's information and that the HeMS 300 can obtain such user information.

If character transmission is set in the manner of notifying the user terminal 500 of service interruption, it is determined whether the CMAS mode is set again (S320). In the embodiment of the present invention, it is assumed that character transmission is selectively performed among SMS and CMAS, but the present invention is not limited thereto.

If the CMAS mode is set, the HeMS 300 transmits a CMAS text message informing the user terminal 500 of the service interruption due to the use of the third-party wired network 600 (S330). Here, the transmission of the CMAS text message can be performed substantially by the CMAS (not shown), and the contents thereof are well known, and a detailed description thereof will be omitted here. Also, the transmission of the CMAS text message can be repeatedly performed a predetermined number of times within a predetermined time.

If the CMAS mode is not set, the SMS message is transmitted to the user terminal 500 (S340). Here, the transmission of the SMS text message can be practically performed by a short message service center (SMSC) (not shown), and the contents thereof are already well known, so a detailed description will be omitted here. In addition, the transmission of the SMS text message can be repeatedly performed a predetermined number of times within a predetermined time.

If the character transmission is not performed in the manner of notifying the user terminal 500 of the service interruption in step S310, the HeMS 300 firstly transmits the redirection transmission to the user terminal 500 QCI for the service is confirmed (S350).

Thereafter, it is determined whether the service of the user terminal 500 is a VoLTE service by the confirmed QCI (S360).
