In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a system for providing an advertisement service in a femtocell environment according to an embodiment of the present invention.

As shown in FIG. 1, the advertisement service system in a femtocell environment according to an exemplary embodiment of the present invention includes a macrocell base station 120, a femtocell AP (Femto Cell Access Point, 131), and a point of sale (POS) terminal. 132, a base station controller 200, an exchange 300, a home location register 400, a gateway 500, and an advertisement server 700.

When the mobile terminal 110 wirelessly connects to the femtocell AP 131, the mobile terminal 110 receives a product list of a store where the femtocell AP 131 is installed. In addition, the mobile terminal 110 may pay for a specific product in the product list to purchase or reserve the product.

The macro cell base station 120 is a BTS (Base Station Transceiver Subsystem) or NodeB, and manages radio resources and is controlled by the control of the base station controller 200. In addition, the base station controller 200 is a base station controller (BSC) or a radio network controller (RNC), which allocates and releases radio channels for the mobile station 110, and transmits the mobile station 110 and the macro cell base station 120. Output control, intercell soft handoff and hard handoff determination, transcoding and vocoding, and operation and maintenance functions for the macrocell base station 120 are performed.

The exchange 300 is a mobile switching center (MSC) or a serving GPRS support node (SGSN), and provides an interface function with the base station controller 200, and controls voice calls, data transmission and reception, and various additional services.

The home location register 400 stores and manages subscriber information, additional service information for each subscriber, location information of the mobile terminal 110, and the like.

The gateway 500 connects the wired broadband network 600 and the mobile communication core network, and the mobile terminal 110 connected to the femtocell AP 131 and the mobile terminal 110 connected to the mobile communication core network. Enable communication between In addition, the gateway 500 transmits data (for example, Internet content) received through the wired broadband network 600 to the mobile terminal 110 connected to the mobile communication core network. In addition, the gateway 500 transmits data (eg, mobile content) received through the mobile communication core network to the mobile terminal 110 connected to the femtocell AP 131. In addition, the gateway 500 performs a protocol conversion function between the mobile communication core network and the wired broadband network 600.

The femtocell AP 131 is mainly for the purpose of guaranteeing the quality of mobile communication services in areas or shadowed areas where the radio wave of the macro cell base station 120 is degraded, such as inside a home or building, or providing a low rate such as a femtozone service. A femtocell base station utilized for the purpose of connecting to a wired broadband network 600, which is a general-purpose Internet circuit. The mobile terminal 110 entering the femtocell region 130 is connected to the femtocell AP 131 and is connected to a wired broadband line and a mobile communication core network through the femtocell AP 131. In general, the femtocell AP 131 supports one frequency and communicates with the mobile station 110 at that frequency.

The femtocell AP 131 periodically transmits broadcast information and a pilot signal, and registers a location of the mobile terminal 110 which attempts to handover to its service area based on this, and wirelessly connects to the mobile terminal 110. In addition, the femtocell AP 131 reports the location registration complete mobile terminal 110 to the advertising server 700. In this case, the femtocell AP 131 transmits the femtocell identifier and the mobile terminal identifier to the advertisement server 700.

Meanwhile, the femtocell AP 131 may be called a micro base station, a pico base station, a ubicell base station, a femtocell base station, or the like according to a policy of a manufacturer or a communication operator. The femtocell 130 may also be called a picocell, ubicell, or the like. Therefore, the femtocell 130 according to the present invention should be understood as being applicable to the case where the femtocell 130 is connected to the core network of the communication system through the general-purpose Internet line to provide the communication service to the mobile terminal 110.

The ad server 700 stores the product list corresponding to the region (ie, the store) in which the femtocell AP 131 is installed. That is, the advertisement server 700 stores the product list corresponding to the femtocell identifier indicating the femtocell region. In particular, when the advertisement server 700 receives a report of access of the mobile terminal 110 from the femtocell AP 131, the advertisement server 700 transmits an advertisement message corresponding to the femtocell identifier to the mobile terminal 110. At this time, the advertisement server 700 transmits a URL for directly accessing the payment screen to the mobile terminal 110 in addition to the advertisement message. In addition, when a payment for a specific product is requested from the mobile terminal 110, the ad server 700 processes the payment, transmits a payment completion message to the mobile terminal 110, and simultaneously pays the payment to the POS terminal 132. Transmitted product information.

The POS terminal 132 is installed in stores such as movie theaters, coffee shops, fast food shops, and food codes, and stores and manages sales information, deposit and withdrawal information, order information, reservation information, and the like. In particular, when the POS terminal 132 receives the payment message of the goods from the advertisement server 700, the POS terminal 132 displays an order request or a reservation request for the goods on the screen. Preferably, the POS terminal 132 displays the payment information of the goods on the screen and outputs to the audio device, thereby recognizing the payment information of the goods to the seller. For example, when the POS terminal 132 receives payment information of a specific food menu from the advertisement server 700, the POS terminal 132 displays the payment information of the food on a screen and outputs it through a specific sound, thereby reminding the seller of the corresponding store. Make sure food is ordered by the customer.

2 is a flowchart illustrating a method for providing an advertisement service to a mobile terminal that enters a femtocell in an advertisement service system according to an embodiment of the present invention.

Referring to FIG. 2, the mobile terminal 110 enters the femtocell region 130 and requests a wireless access to the femtocell AP 131 that manages the femtocell region (ie, a specific burial region) (S201). Then, the femtocell AP 131 establishes a Radio Resource Control (RRC) connection with the mobile terminal 110 and allocates a radio resource (S203). In detail, the femtocell AP 131 receives an RRC connection request message from the mobile terminal 110 and accordingly transmits an RRC connection setup message to the mobile terminal 110. The mobile station 110 allocates radio resources. The femtocell AP 131 receives an RRC connection setup complete message from the mobile station 110 in response to the RRC connection setup message.

As such, when the RRC connection with the femtocell AP 131 is completed, the mobile terminal 110 transmits a location update request message according to the change of the location of the connected base station, and the location registration request message is a femtocell. It is transmitted to the exchange 300 via the AP 131, the wired broadband network 600 and the gateway 500 (S205, S207). Next, the exchange 300 requests the home location register 400 to update the location information of the mobile terminal 110, and the home location register 400 has the mobile terminal 110 located in the femtocell area 130. Register and transmit a location update complete message (Location Update Complete) to the exchange 300. Then, the exchange 300 transmits a location updated response to the femtocell AP 131 via the gateway 500 and the wired broadband network 600 (S209).

When the femtocell AP 131 receives the location registration response message of the mobile terminal 110, the femtocell AP 131 transmits a location registration response message to the mobile terminal 110, and also transmits the location registration response message to the mobile terminal 110. Report the location registration of 110 is completed (S211, S213). In this case, the femtocell AP 131 transmits the femtocell identifier and the mobile terminal identifier to the advertisement server 700. Then, the advertisement server 700 extracts a product list based on the received femtocell identifier, writes it as an advertisement message, and transmits it to the mobile terminal 110 (S215 and S217). That is, the advertisement server 700 extracts a product list of a store covered by the femtocell AP 131 based on the femtocell identifier, writes the product list as a message, and receives a mobile terminal corresponding to the received mobile terminal identifier ( 110). In this case, the advertisement server 700 transmits the callback URL directly accessible to the payment screen to the mobile terminal 110 in addition to the advertisement message.

3 is a diagram illustrating an advertisement message including a product list according to an embodiment of the present invention.

As shown in FIG. 3, the mobile terminal 110, which is connected to a femtocell AP 131 that manages a specific store and registers a location, receives a message about a product list of the store. The advertisement message shown in FIG. 2 represents a list of products that can be cooked in the KTF Korean restaurant transmitted to the mobile terminal 110 entering the KTF Korean restaurant. The mobile terminal 110 receiving the advertisement message may request a payment by selecting any one of the received product list. In addition, the mobile terminal 110 may request the payment by inputting the quantity of the corresponding product, and may request the payment by selecting several products together.

4 is a flowchart illustrating a method of receiving a payment request for a specific product from a mobile terminal and performing a payment processing in an advertisement service system according to an embodiment of the present invention.

Referring to FIG. 4, the mobile terminal 110 receiving an advertisement message in which a product list is recorded, selects a specific product among them, and requests payment for the product (S401 and S403). Then, the ad server 700 performs a payment authentication procedure for the mobile terminal 110 and the corresponding product (S405). That is, the advertisement server 700 requests the mobile terminal 110 to select a payment method (for example, credit card payment, mobile phone payment, etc.) and performs subscriber authentication in response to the selected payment method. For example, when the card payment method is selected, the advertisement server 700 performs credit card authentication such as a social security number, card password, and card serial number of the subscriber.

Next, when the payment is normally completed, the advertisement server 700 generates a purchase identification number and transmits a payment completion message to the mobile terminal 110 indicating that the payment for the corresponding product is normally completed (S407). The purchase completion number is recorded in the payment completion message. Subsequently, the advertisement server 700 transmits the purchase identification number and the paid product information to the POS terminal 132 (S409). Then, the POS terminal 132 displays the product information on the screen and outputs it through a specific sound, thereby notifying the seller that the corresponding product is ordered, reserved or purchased (S411). For example, when the POS terminal 132 is a terminal installed in a movie theater and receives payment information for a movie reservation from the ad server 700, the ticket seating information of the user is changed at the same time to enable or disable the movie seat. Save and output the ticket reservation information on the screen or speaker.

As described above, when the subscriber enters a specific store in which the femtocell AP 131 is installed, the subscriber may receive a list of products sold in the store and purchase a specific product therefrom. In addition, the seller may check the product information ordered online through the POS terminal 132 without having to receive a product order directly facing the customer to process the purchase of the product. That is, the customer may conveniently apply for the purchase or reservation of the product in the current location through the mobile terminal 110, and the seller may reduce the labor generated when the customer orders the product.

Meanwhile, the mobile station 110 searches for another cell only when the frequency signal of the cell to which the cell is currently connected is lowered below the cell reselection threshold. However, since the macro cell base station 120 communicates with the mobile station 110 using different frequencies to secure more radio channels, when the femtocell and the macrocell use different frequencies, the macro cell in the femtocell region 130 Since the signal interference phenomenon of the cell base station 120 does not occur, the mobile station 110 may not hand over to the femtocell AP 131.

For example, when the mobile terminal 110 moves to the femtocell region 130 using the F2 frequency included in the macrocell region 100 while the mobile terminal 110 is connected to the macrocell base station 120 at the F1 frequency, the macro Signal interference does not occur because the frequency F1 of the cell base station 120 and the frequency F2 of the femtocell AP 131 are different. Accordingly, the mobile terminal 110 recognizes that the frequency F1 of the macro cell base station 120 does not fall below the cell reselection threshold value, and thus does not hand over to the femtocell AP 131. Will continue to communicate with).

In other words, if the femtocell frequency and the macrocell frequency are the same, the frequency transmitted from the femtocell AP 131 interferes with the macrocell frequency, and the frequency of the macrocell base station 120 in the femtocell region 130 is attenuated. . That is, when the mobile terminal 110 moves to the femtocell region 130 while being connected to the macrocell base station 120 at the same frequency as the femtocell frequency, the mobile terminal 110 moves to the femtocell AP 131 due to the frequency transmitted from the femtocell AP 131. The frequency intensity of 120 is attenuated. Accordingly, the mobile terminal 110 recognizes that the frequency signal of the currently accessed macro cell is lowered to a level below the cell reselection threshold value, and proceeds with the cell reselection process, and the femtocell AP 131 having a relatively strong signal strength is present. Connect (ie, handover).

On the contrary, when the mobile terminal 110 enters the femtocell region 130 while being connected to the macrocell base station 120 at a frequency different from the femtocell frequency, the communication frequency of the macrocell base station 120 and the mobile terminal 110 is different. Is not subject to signal interference by the frequency transmitted from the femtocell AP 131. Accordingly, the mobile terminal 110 recognizes that the frequency strength of the macro cell base station 120 does not decrease below the reselection threshold value, even if the mobile station 110 is located in the femtocell region without proceeding with the cell reselection procedure. Continue to communicate with 120). That is, since the mobile station 110 satisfies the frequency strength received from the macro cell base station 120 as the strength required for communication, the mobile terminal 110 does not perform unnecessary handover.

Since the frequency of the macro cell 100 and the frequency of the femtocell 130 are different, if the mobile terminal 110 fails to access the femtocell AP 131, the advertisement message according to the present invention is also sent to the mobile terminal 110. Could not send Therefore, the communication frequency between the mobile terminal 110 and the macrocell base station 120 preferably matches the frequency of the femtocell region 130 included in the macrocell region 100.

5 is a diagram illustrating a configuration of a system for providing an advertisement service in a femtocell environment according to another embodiment of the present invention.

Among the components of FIG. 5, the components denoted by the same reference numerals as those of FIG. 1 play the same role as the components of FIG. 1, and thus, the description with reference to FIG. 5 will be described based on differences from FIG. 1.

The macro cell base stations 120-1 and 120-2 perform the same role as the base station 120 of FIG. 1, but communicate with the mobile station 110 using a plurality of different frequencies to secure more radio channels. do.

The base station controller 200-1 is a base station controller (BSC) or a radio network controller (RNC), which allocates and releases radio channels to the mobile station 110, and transmits the mobile station 110 and the macro cell base station 120. Output control, intercell soft handoff and hard handoff determination, transcoding and vocoding, and operation and maintenance functions for the macrocell base station 120 are performed. In particular, when the mobile station 110 attempts to handover between the macro cells 100-1 and 100-2, the base station controller 200-1 controls the movement within the macro cell 100-2 that is attempted to be handed over. The terminal 110 receives and receives the frequency information of the femtocell AP 131 accessible to the femtocell management server 800. In addition, the base station controller 200-1 transmits the received femtocell frequency information to the mobile station 110, thereby transmitting a communication frequency between the mobile station 110 and the macrocell base station 120-2 to the femtocell frequency F2. Transition to

The femtocell management server 800 stores femtocell frequency information included in each macrocell region 100-1, 100-2. In particular, when the femtocell management server 800 receives the femtocell frequency request from the base station controller 200-1, the femtocell 130 extracts the frequency of the femtocell 130 in the macro cell 100-2 that the mobile terminal 110 attempts to handover. The frequency information is transmitted to the base station controller 200-1.

Hereinafter, it is assumed that the mobile terminal 110 moves from the macro cell 1 100-1 to the macro cell 2 100-2, and targets the base station 120-2 of the macro cell 2 which attempts to handover. This is referred to as a base station.

6 is a flowchart illustrating a method of transitioning a communication frequency between a base station and a mobile station to a femtocell frequency in order to induce connection of a mobile station to a femtocell area in an advertisement service system according to an embodiment of the present invention.

Referring to FIG. 6, the mobile terminal 110 enters the macro cell 2 region 100-2 from the macro cell 1 region 100-1 (S601). Subsequently, as the frequency signal received from the base station 120-1 of the macro cell 1 becomes lower than or equal to the cell reselection threshold, the mobile station 110 rescans the cell and is transmitted from the target base station 120-2. The pilot signal and the broadcast information are received and the RRC connection (Radio Resource Control Connection) is established with the base station controller 200-1 through the target base station 120-2 (S603). That is, the mobile terminal 110 performs the cell search, where the existing location information (ie, macro cell 1 location information) is included in the broadcast information received from the target base station 120-2 (ie, macro cell 2). Location information) and establishes an RRC connection with the base station controller 200-1 to request a location update accordingly. At this time, the mobile terminal 110 selects any one of the communication frequencies (F1, F2) of the target base station 120-2 and communicates with the target base station 120-1.

The mobile terminal 110 which has established the RRC connection transmits a location update request message, and the location registration request message is exchanged through a target base station 120-2 and a base station controller 200-1. It is passed to 300 (S605). Next, the exchange 300 requests the home location register 400 to update the location information of the mobile terminal 110, and the home location register 400 indicates that the mobile terminal 110 is the target base station 120-2. It registers that it is located in the service area (ie, macro cell 2) and transmits a location update complete message (Location Update Complete) to the exchange 300.

In response to receiving the location registration completion message, the switch 300 transmits a location update response message indicating that location registration is normally completed to the mobile station 110, and sends an Iu release message to the base station controller 200-1. Request to release the radio resource allocated to the mobile station 110 to the base station controller 200-1 (S607, S609). Then, the base station controller 200-1 recognizes that the mobile terminal 110 is normally connected to the target base station 120-2, and requests femtocell frequency information from the femtocell management server 800 (S611). At this time, the base station controller 200-1 transmits the target base station 120-1 identifier to the femtocell management server 800.

Next, the femtocell management server 800 extracts the femtocell frequency F2 included in the macrocell 2 region 100-2 based on the target base station 120-1 identifier and transmits the frequency information to the base station controller 200-. 1) (S613). Then, the base station controller 200-1 compares the femtocell frequency received from the femtocell management server 800 and the frequencies currently communicated between the mobile station 110 and the target base station 120-2. If the two frequencies are different, the base station controller 200-1 transmits an RRC connection release message including the femtocell frequency F2 to the mobile station 110 (S615). At this time, the base station controller 200-1 records the femtocell frequency information of the mobile station 110 in "Redirection Info" included in the RRC connection release message and transmits it.

Then, the mobile terminal 110 transmits an RRC Connection Release Complete message to the base station controller 200-1 and releases the RRC connection established with the base station controller 200-1 (S617). Subsequently, when the femtocell frequency F2 is included in the RRC connection release message, the mobile station 110 changes the communication frequency communicating with the target base station 120-2 to the femtocell frequency F2 (S619). For example, even if the mobile terminal 110 entering the macro cell 2 region 100-2 communicates with the target base station 120-2 at the F1 frequency to register its location, the RRC connection release message to which the femtocell frequency F2 is added is added. When receiving, the communication frequency with the target base station 120-2 transitions from F1 to F2.

Meanwhile, when the femtocell frequency received from the femtocell management server 800 and the frequency at which the mobile station 110 communicates with the target base station 220 are the same, the base station controller 200-1 performs the RRC release message without the femtocell frequency. Is transmitted to the mobile terminal 110 to maintain the communication frequency between the mobile terminal 110 and the target base station 120-2 in the present state.

Next, the mobile terminal 110 whose communication frequency with the target base station 120-2 is matched with the femtocell frequency enters the femtocell region 130 (S621). The mobile station 110 recognizes that the frequency signal transmitted from the target base station 120-2 is lowered below the cell reselection threshold according to the frequency interference of the femtocell AP 131, and searches for a neighboring base station to search for a femtocell AP. The frequency signal of 131 is sensed (S623). As the base station communicating changes, the mobile station 110 establishes an RRC connection with the femtocell AP 131 to request a location update (S625). The mobile terminal 110 having established the RRC connection transmits a location update request message to the femtocell AP 131 requesting location update (S627), and registers the location as shown in steps S207 to S217 of FIG. After the completion, the product list of the store under the control of the femtocell AP 131 is received from the advertisement server 700.

By the above-described method, the mobile terminal 110 changes the communication frequency with the target base station 120-2 to the femtocell frequency F2 at the time of handover between the macrocells 100-1 and 100-2. Thereafter, when entering the femtocell region 130, it is recognized that the frequency strength of the target base station 120-2 is lowered below the cell reselection threshold due to signal interference. Accordingly, the mobile terminal 110 releases the connection with the target base station 120-2, accesses and registers the location of the femtocell AP 131 having a relatively strong frequency signal, and stores the location of the store where the femtocell AP 131 is installed. Receive an advertising message.

As described above, the present invention prevents the situation in which the subscriber does not receive the advertisement message of the corresponding store because it is not handed over to the femtocell even if the subscriber enters the femtocell region 130. In addition, in the present invention, even if the femtocell region 130 overlaps the macrocell region 100-2, an advertisement message is smoothly transmitted to the mobile terminal 110 by inducing a handover to the femtocell 130 through the method of FIG. 6. send.
