FIG. 1 is a diagram showing a structure of a data service apparatus according to a first embodiment of the present invention, and FIG. 2 is a diagram showing a structure of an SGSN constituting a communication network of FIG.

1 and 2, the data service apparatus according to the first embodiment of the present invention includes a communication network 120 including a network device such as an MSC or an SGSN, and a data path management server 140. [ The data service apparatus may further include a part or all of the terminal 100, the access point (AP) 110, the additional service network 130, and the data receiving apparatus 150.

The terminal 100 according to an embodiment of the present invention can be applied to various wired and wireless environments and includes a personal digital assistant (PDA), a cellular phone, a smart phone, and the like classified by terminal type, a personal communication service (PCS) A Global System for Mobile (GSM) phone, a Wideband CDMA (W-CDMA) phone, a CDMA-2000 phone, and a Mobile Broadband System (MBS) phone. Here, the MBS phone represents the terminal 100 to be used in the next generation system currently being discussed. Furthermore, the terminal 100 according to the embodiment of the present invention may further include a desktop computer, a laptop computer, and the like.

The terminal 100 may include a wireless communication module, a wireless LAN module, and a GPS module. The mobile terminal 100 is connected to the communication network 120 and performs normal voice communication and data communication with the other party. In addition, the terminal 100 can receive various web page data by accessing the communication network 120 via the AP 110 which is perceived as surrounding by the wireless LAN module. Furthermore, the terminal 100 may be classified into a GPS terminal and a non-GPS terminal depending on whether the GPS module is provided or not. When the terminal 100 includes a GPS module, the terminal 100 receives data provided through a GPS satellite.

The terminal 100 may be an Internet access protocol (WAP), an HTML-based MIE (Microsoft Internet Explorer), a Handheld Device Transport Protocol (HDPT), an NTT And connects to the Internet via the communication network 120 using the i-Mode of DoKoMo or a browser for wireless Internet access of a specific communication company. Of the Internet access protocols used in the terminal 100, the MIE uses m-HTML, which slightly reduces and modifies the HTML, and the i-Mode uses a language called compact HTML (c-HTML) do.

In order to provide a faster wireless Internet, a terminal 100 such as a smart phone in recent years uses a browser for a wireless Internet access of a specific communication company such as Opera Mini for iPhone, Wi-Fi and WiBro, which are communication networks, are also used to provide wireless broadband internet.

The AP 110 includes a small base station such as a femto or pico base station, which is installed in a large number of buildings. Here, the femto or pico base station is classified according to the maximum number of the terminals 100 that can be connected to the small base station. Also, the AP 110 includes a short-range communication module for performing short-range communication such as Wi-Fi with the terminal 100. In the exemplary embodiment of the present invention, the short-range communication may include a radio frequency (RF) and ultra-wideband communication such as Bluetooth communication, zigbee communication, IrDA, UHF and VHF (UWB), and the like. Accordingly, the AP 110 can extract the location of the data packet, specify the best communication path to the extracted location, and forward the data packet to the terminal 100, the exchange, or the like along the designated communication path. The AP 110 may share a plurality of lines in a general network environment and may include a router and a repeater.

The communication network 120 includes all of wireless communication networks such as a synchronous (CDMA) network, an asynchronous (WCDMA) network, a GSM network, and an LTE (Long Term Evolution) network. The communication network 120 is not limited to the above communication network because the communication network may be any communication network capable of performing wireless communication with the terminal 100. The communication network 120 may also be a wired communication network such as a public switched telephone network (PSTN) As shown in FIG.

For example, the WCDMA network may include a Node B, an RNC (Radio Network Controller), an MSC, an SGSN, and a Gateway GPRS Support Node (GGSN). Furthermore, the WCDMA network may further include a Visitors Location Register (VLR) and a Home Location Register (HLR) (or Home Subscriber Sever (HSS)). Here, the RNC relays the voice or data call between the Node B and the MSC or between the Node B and the SGSN. Of course, the NodeB and the RNC in the WCDMA network can be replaced with a BTS (Base Station Transmission System) and a BSC (Base Station Controller), respectively, in the case of a CDMA network. In the EPC (Evolved Packet Core) network, it can be replaced with an evolved base station (e-NodeB) and a mobility management entity (MME). The MME is an integrated form of an RNC and an SGSN in a WCDMA network. It is almost the same.

The NodeB is arranged in each cell, for example, and receives a call request signal from the terminal 100 through a traffic channel of the signal channel, transmits the received call request signal to the RNC, And performs location registration for grasping the location of the terminal 100 existing in the cell area to which the terminal 100 is subject. The NodeB is a network endpoint device directly connected to the terminal 100, and performs baseband signal processing, wired / wireless conversion, and wireless signal transmission / reception. If the terminal 100 in the cell area of the Node B is a receiving side, the Node B determines the location of the terminal 100 and then transmits a call request signal transmitted from the MSC through the RNC.

In addition, the Node B can obtain information such as the position and the longitude of the Node B by using a signal from the GPS satellite, and can transmit the position information of the Node B to the terminal 100 through the system parameter message of the forward link paging channel. The terminal 100 may register the new location information by calculating the moving distance of the terminal 100 using the location information of the NodeB of the cell to which the terminal 100 belongs. Here, the location registration is a processing procedure for notifying the MSC of the location, state, identifier, slot period, and other characteristics of the terminal 100 to the MSC through the Node B. When the Node B desires to set the reception signal to the terminal 100, 100) to be called effectively. The location registration of the terminal 100 is performed when the terminal 100 is powered on or off, when the terminal 100 moves between MSCs, and when the parameters of the terminal 100 are changed . ≪ / RTI >

The RNC controls the NodeB, allocates and releases radio channels for the MS 100, transmission output control of the MS 100 and the Node B, soft handoff and hard handoff decision between cells, (GPS) distribution, operation and maintenance functions for the NodeB, and when the terminal 100 moves between the NodeBs according to the embodiment of the present invention, for example, an additional service The MS or the SGSN, as the location information of the terminal 100, node or base station information such as the changed cell ID. In addition, the RNC transmits a call request signal transmitted from the terminal 100 via the Node B to the MSC, and conversely, the RNC transmits the call request signal transmitted from the MSC to the terminal 100 via the Node B.

The MSC performs base and supplementary service processing, subscriber reception and outgoing call processing, location registration and handoff procedure processing, and interworking with other networks. For example, the MSC of the IS-95 / A / B / C system includes an Access Switching Subsystem (ASS) for performing distributed call processing, an Interconnection Network Subsystem (INS) for performing centralized call processing, A Central Control Subsystem (CCS) for centralizing maintenance functions, and a Location Registration Subsystem (LRS) for storing and managing information about mobile subscribers. MSCs for third and fourth generations can also include an Asynchronous Transfer Mode (ATM) switch, which increases the transmission speed and efficiency of line use with packet transmission per cell. When the location registration of the MS 100 is performed through the Node B and the RNC, the MSC temporarily stores subscriber information of the MS 100 in the VLR and requests location registration of the MS 100 with the HLR.

The VLR receives the location information of the visited subscriber from which the location information registration is performed from the MSC. When the terminal 100 performs location information registration, the VLR temporarily stores the subscriber information, notifies the HLR of the subscriber information, receives a copy of the terminal identification number, terminal unique number, and service information of the terminal 100 from the HLR And performs functions such as position control of the terminal 100, call processing, and external operation processing.

The HLR receives location information of the terminal 100 from the VLR and performs functions such as registration recognition, registration deletion, and location confirmation. Also, the HLR stores subscriber information of the terminal 100 waiting for a call. Here, the subscriber information refers to MIN (Mobile Identification Number), ESN (Electronic Serial Number) and / or mobile communication service information of the terminal 100. Of course, the subscriber information in the HSS may include Mobile Station Integrated Server Digital Network (MSISDN), International Mobile Subscriber Identity (IMSI), International Mobile Equipment Identities (IMEI), Access Point Name (APN) . In addition, according to the embodiment of the present invention, the HLR may analyze the subscriber information in addition to providing subscriber information through the MSC or the SGSN, and may determine whether subscription is included in a specific supplementary service such as an intelligent network service, Even when the terminal 100 subscribed to the specific supplementary service moves between NodeBs, it can additionally determine whether to join the supplementary service according to the changed location information and provide the determination result. The determination result may be included in the subscriber information or may be configured separately.

Of course, the determination as to whether or not to join the supplementary service may be made at any one of the data path management server 140, the MSC, the VLR, and the SGSN rather than the HLR as in the embodiment of the present invention. For example, when the terminal 100 attempts to access a data call or the location of the terminal 100 is changed, the SGSN receives the location information and transmits the location information to the VLR. Then, the VLR provides the location information to the HLR, And then the VLR analyzes the subscriber information to determine whether or not the subscriber is subscribed to the specific supplementary service, and provides the determination result to the data path management server 140 via the SGSN to determine the service zone . On the other hand, if the SGSN provides the data path management server 140 with the location information and the subscriber information of the terminal 100 temporarily stored in the VLR, the data path management server 140 determines the presence / It can be determined first whether or not the user is subscribed to the specific supplementary service. This can be considered in a direction that can reduce the load on network devices such as MSC, VLR, and SGSN. Therefore, as in the embodiment of the present invention, only a determination result If so, it would be desirable to provide the VLR or HLR with the results of the judgment.

The SGSN can interwork with the data path management server 140 and the GGSN. The SGSN supports session management, authentication and billing functions for handling mobility management, outgoing / incoming call processing procedures, and packet data transmission / reception for the GPRS (General Packet Radio Service) with the GGSN . It also has routing function of packet data.

For example, when the SGSN 100 attempts to access a data call of the terminal 100 or when the terminal 100 moves between NodeBs, the SGSN transmits location information such as a node or base station information from the HLR to the subscriber And transmits some or all of the location information and the subscriber information to the data path management server 140. [ And receives the determination result determined by the data path management server 140 using part or all of the transmitted location information and subscriber information. Here, the determination result is, for example, a result of determining whether the terminal 100 attempting to access the data call or the terminal 100 where the location change has occurred is in the service zone, for example, in the business establishment. According to the determination result, the SGSN or the GGSN selects an intranet and an internet path in the supplementary service network 130 to transmit data call or data traffic to the data reception device 150.

In this process, if the determination result of the data path management server 140 according to the location information provided when attempting to access the data call of the terminal 100 and the determination result of the data path management server 140 according to the location information of the changed terminal 100 If the result of the re-determination is the same, the SGSN or the GGSN maintains the intranet and the Internet route in the first selected supplementary service network 130. However, if the two determination results are different, the data session for the corresponding data call is terminated, The SGSN may re-execute the data call setup process with the GGSN or the like so that the intranet and the Internet path in the supplementary service network 130 can be changed according to the determination result.

2, the SGSN includes a call processing unit 200, a memory unit 210 and a data session management unit 220. The call processing unit 200 includes an interface unit 200, (Not shown) and a control unit (not shown).

Here, the interface unit may transmit the subscriber information provided by the HLR based on the location information and the location information of the terminal 100 provided when the mobile terminal 100 attempts to access a data call or when the mobile terminal moves between nodes, The management server 140 performs a role of relaying and delivering a determination result about the inside or outside of the service zone. In this process, the interface unit may perform protocol conversion for communication between the data path management server 140, the RNC, the VLR, the HLR, and the GGSN, or may perform functions such as information conversion such as encoding or decoding.

The control unit controls the entire call processing performed in the SGSN. According to an embodiment of the present invention, the control unit receives the location information of the terminal 100 provided by the RNC when attempting to access the data call of the terminal 100 through the interface unit and provides the HLR to the subscriber information provided by the HLR, Lt; / RTI > And also provides location information or subscriber information provided by the HLR to the data path management server 140 and receives a determination result as to whether the location information or the subscriber information exists in the service zone from the data path management server 140. And then performs a data call setup process with the GGSN or the like according to the determination result to select the Internet or intranet path of the supplementary service network 130. [ And the location information and the determination result provided by the data path management server 140 in the memory unit 210.

If the movement of the Node B between the Node Bs occurs in the process of using the data service, the controller receives the changed position information of the terminal 100 provided by the RNC through the interface unit and repeats the above process. In this process, the control unit provides the data session management unit 220 with the re-determination result of the data path management server 140 according to the changed location information, and compares the result with the determination result stored in the memory unit 210 to determine whether there is a service zone change . As a result of the comparison, if the service zone is not changed, the control unit receives the comparison result from the data session management unit 220 and maintains the current data session. If a service zone change occurs, the controller terminates the corresponding data session and performs a data traffic reset process with the GGSN to change the path.

The memory unit 210 stores the subscriber information provided by the HLR or the location information provided by the HLR and the subscriber information according to part or all of the subscriber information according to the location information provided when the terminal 100 attempts to access the data call, ) Can be stored under the control of the control unit.

The data session management unit 220 compares the determination results provided by the data path management server 140 with each other based on the determination result stored in the memory unit 210 and the changed position information of the changed terminal 100, To the control unit. Accordingly, the control unit can perform maintenance or termination of the current data session using the comparison result.

If the GGSN is designed to select one of the intranet and the Internet in the supplementary service network 130, the SGSN may compare the determination result provided from the data path management server 140 and the changed location information of the terminal 100 The GGSN sends the result to the GGSN, and the intranet and the Internet path of the supplementary service network 130 are selected and selected, and the data traffic from the terminal 100 is transmitted to the data receiving apparatus 150 The present invention is not particularly limited to this.

The GGSN is a serving node of an IP-based packet network that provides a high-speed packet data service for GPRS. The GGSN performs session management for packet data service and routing processing of packet data. The GGSN is a wired communication network The GGSN provides an interface for connecting the supplementary service network 130 to the GGSN. Further, according to the embodiment of the present invention, when the data traffic with the SGSN is established, the corresponding data traffic provided by the SGSN is indicated in the service zone It is possible to allocate an originating IP in order to do so. Here, GPRS is an asynchronous communication system for supporting a data transmission rate of 384 Kbps, providing multimedia mail, and maximizing the efficiency of a transmission line by data transmission per packet.

The supplementary service network 130 can be divided into the Internet and the intranet according to the embodiment of the present invention. 1, the supplementary service network 130 is illustrated as being separated from the communication network 120, but may be substantially included in the communication network 120. However, in the supplementary service network 130 according to the embodiment of the present invention, when the subscriber of the subscriber who uses the subscriber station 100 is registered as a subscriber rather than a subscriber, One of the Internet and intranet routes is used under the control of the SGSN or GGSN of the communication network 120 when the service zone is within the benefit zone.

For example, when the terminal 100 attempts to access a data call within the service zone, the intranet of the supplementary service network 130 transmits data traffic from the terminal 100 to the data receiving apparatus 150 under the control of the SGSN or the GGSN. When the terminal 100 attempts to access a data call outside the service zone, the Internet transmits data traffic from the terminal 100 to the data receiving apparatus 150 under the control of the SGSN or the GGSN . In this way, the selected path when attempting to connect the data call can be maintained or changed in accordance with the movement of the terminal 100.

Also, according to the embodiment of the present invention, the intranet may include a gateway for controlling the connection of the enterprise intranet. For example, the gateway checks the outgoing IP information allocated by the GGSN. If the data call is originated in the service zone, the gateway opens the intranet to transmit the data traffic, checks the outgoing IP information, , The intranet may be blocked to prevent the data traffic from being transmitted.

Here, an intranet refers to an information system that integrates intra-organizational tasks using Internet-related technologies and communication protocols. In other words, it means an information system redeveloped by using various information systems that have been used so far so that they can be used by using the Internet. And generally includes connections through one or more gateways connected to the external Internet. Using an intranet allows an organization to use its own information system anywhere in the world without having to establish a separate communication network, and it is easy to exchange data with other organizations that have business relations, . This is because intranets can easily integrate information systems of organizations scattered around with different attributes and can be applied simply and widely using the global standard of the Internet, .

The data path management server 140 can interwork with the SGSN or the GGSN. The data path management server 140 receives the data which the terminal 100 tried to access using some or all of the subscriber information provided from the HLR through the location information and location information of the terminal 100 provided by the SGSN, It is determined whether the call is made within the service zone or outside the service zone. And provides the SGSN with the result of the judgment on the inside and the outside of the service zone. In addition, the data path management server 140 receives the subscriber information according to the changed location information and the changed location information from the HLR even when the mobile terminal 100 moves between NodeBs, And further provides a re-determination result to the SGSN.

The data path management server 140 may include a database (not shown), and the database stores a comparison value for providing a determination result using the provided location information and subscriber information according to a location determination request from the SGSN do. Here, the comparison value may be the information that the data path management server 140 requests when the subscriber terminal 100 subscribes to the subscriber's location information and supplementary service information. Such information is stored in the HLR whenever the new subscriber is generated or updated, and additional service information and location information for each subscriber are stored. Of course, since the data path management server 140 can store additional service information and location information for each subscriber as a comparison value in the database, the data path management server 140 can store the supplementary service information and the location information in the database at the time of a data call connection attempt, 100 can be compared with the comparison value stored in the database to determine the inside and the outside of the service zone.

The data receiving apparatus 150 may include a server or a laptop computer for receiving the data traffic of the terminal 100. Of course, the data receiving apparatus 150 according to the embodiment of the present invention may be various receiving apparatuses other than a server and a laptop computer, and therefore, the present invention is not limited thereto.

In the meantime, according to the embodiment of the present invention, the call processing procedure of the SGSN and the data path management server 140 has been described with respect to the data service. However, in the case of the voice call made in the MSC, It is not limited to the data path management only. Accordingly, the data path management server 140 may be collectively referred to as a path management server in the sense of integrally managing data and voice paths.

In addition, although the SGSN and the GGSN are described in the WCDMA network as an example in the present invention, they can be replaced by a PDSN (Packet Date Serving Node) in a CDMA network and an ACR (Access Control Router). Therefore, it can be broadly referred to as a network device for exchanging data as a concept of a wide range including it, and may be referred to as a network device if it further includes a voice exchange. From the same viewpoint, the HLR or HSS can be included in the subscriber information management server, which is a broad concept applicable to other communication networks.

3 is a diagram illustrating a service process of the data service apparatus of FIG.

Referring to FIG. 3 together with FIG. 1 and FIG. 2, a call procedure for packet data communication is started by the MS 100 transmitting a PDP (Context PDP Context Request) message to the SGSN (S301). In this step, a minimum required air channel is secured between the terminal 100 and the RNC.

Here, the PDP context activation request message includes parameters such as a PDP address, an Access Point Name (APN), and a Quality of Service (QoS). The PDP address indicates the IP address of the terminal 100 used in the UMTS packet switching domain. The APN indicates an access point of the service network to which the terminal 100 requesting to create a GTP tunnel currently requests access , And QoS indicates the quality of packet data transmitted through a currently generated GTP tunnel.

Upon receiving the PDP context activation request message from the terminal 100, the SGSN uses the APN to obtain the address of the GGSN to be a destination of packet data transmission, that is, a GGSN to be a GTP tunnel. At this time, the SGSN may inquire an external DNS (Domain Name Server) (not shown) to obtain the corresponding GGSN address, if necessary.

The SGSN confirms the QoS bandwidth for the GTP tunnel, acquires resources, and allocates a tunnel endpoint identifier (TEID) to the GGSN. The TEID is set to transmit packet data between network nodes using a GTP tunnel. Generally, the TEID is set to include a number of a user traffic module (hereinafter referred to as a traffic module) to be used for transmission of packet data and a call ID in a corresponding traffic module.

The SGSN that has allocated the TEID searches the routing table according to the obtained GGSN address to obtain its own Gn port address with the lowest cost. This Gn port address is used by the SGSN to communicate with the GGSN. Also, the SGSN obtains the Iu port address for communicating with the RNC using the RNC-ID received from the RNC.

Then, the SGSN transmits a Create PDP Context Request message including the obtained Gn port address and the TEID allocated to the GGSN to the GGSN (S303). At this time, the SGSN stores the TEID of the GGSN, and the GGSN stores the TEID of the SGSN. These TEIDs are included in the PDP context information, respectively.

Upon receiving the PDP context creation request message from the SGSN, the GGSN performs an authentication procedure using the APN and allocates a PDP address. At this time, the GGSN can request the PDP address to the external server according to the service type.

The GGSN transmits to the SGSN a Create PDP Context Response message including a TEID and a Gn port address assigned to the SGSN by the GGSN (S305). The PDP creation response message includes the TEID that the SGSN should use when transmitting packet data to the GGSN. This completes the creation of the GTP tunnel between the SGSN and the GGSN, and the actual packet data transmission becomes possible due to the generation of the GTP tunnel.

The SGSN transmits an Activate PDP Context Accept message including the TEID_RNC and the IP address to the terminal 100 (S307). Upon receiving the PDP activation acceptance message, the terminal 100 generates a radio channel between the terminal 100 and the RNC, thereby completing a GTP tunnel between the RNC, the SGSN, and the GGSN. From this time, the terminal 100 can transmit / receive all packet data transmitted to its own PDP address. In other words, the terminal 100 can perform packet service and communicate with an external host. The actual packet data, i.e. traffic, is encapsulated in a GTP tunnel generated by the call procedure, and the GGSN finally encapsulates / decapsulates the GTP tunnel.

Also, when the data call provided by the terminal 100 corresponds to a subscriber's call, the SGSN sets a path for transmitting data traffic to the GGSN by distinguishing the Internet or intranet of the supplementary service network 130, for example.

For this, the SGSN transmits the subscriber information provided from the HLR, for example, as initial DP (Initial Data Packet) information to the data path management server 140 using the location information provided in the data access attempt of the terminal 100 and the location information (S309). Here, the subscriber information may include a service key of the supplementary service information or information on whether the supplementary service is to be added.

The data path management server 140 determines whether the terminal 100 that has attempted to access the data call is located in the service zone by using part or all of the location information and the subscriber information (S311).

At this time, the data path management server 140 may first determine whether it is subscribed to the supplementary service before determining whether it is located in the service zone. The data path management server 140 determines whether the data call of the terminal 100 is made in the service zone based on the location information.

For example, the data path management server 140 determines whether or not the subscriber is subscribed to the supplementary service and whether the subscriber's supplementary service information and location information are provided in the service zone And compare the supplementary service information and the location information received from the SGSN when the terminal 100 attempts to access the data call with the comparison value stored in the database. Of course, in the embodiment of the present invention, the comparison values may be stored in the database and not compared, but may be requested and provided by the HLR whenever necessary.

When the determination process is completed, the data path management server 140 provides the determination result of the location of the zone to the SGSN (S313). At this time, as a determination result, the data path management server 140 may provide a message in which the gprsCause value for GPRS is set, for example.

The SGSN performs a data call setup process according to the determination result received from the data path management server 140 (S315). Herein, the data call setup process is a process in which, for example, the SGSN transmits the determination result received from the data path management server 140 to the GGSN, and the GGSN permits and blocks access to the intranet and the Internet belonging to the supplementary service network 130 , And further, the GGSN may add an originating IP to the data packet.

According to this procedure, the GGSN may provide the data traffic provided by the SGSN to the data receiving apparatus 150 (S317).

If the movement of the terminal 100 between the NodeBs, for example, outside the service zone occurs, the RNC transmits the changed location information of the terminal 100 to the SGSN (S319 ).

The SGSN can then repeat the above process. In other words, the changed location information is provided to the HLR to receive the subscriber information, and the changed DP information including the changed location information and subscriber information is provided to the data path management server 140 (S321). Here, the subscriber information may include a determination result as to whether or not the terminal 100 joins the supplementary service.

In step S323, the data path management server 140 re-determines whether it is located in the service zone by using part or all of the changed location information and the subscriber information.

If the data path management server 140 provides the SGSN with the result of the re-determination (S325), the SGSN maintains the current data session (S327). Here, the management determines whether to hold or to end the currently connected data session by comparing the received re-determination result and the determination result stored in the memory, that is, the determination result used in the data call connection attempt, The session is terminated when the termination of the session is required.

The SGSN then provides the GGSN with information related to maintenance or termination of the data session to request to maintain the established data call or reset the data call (S329). If a data call reset is required, the GGSN will change the data traffic transmission path. Here, the data traffic transmission path represents the Internet and the intranet mentioned above.

When the maintenance or re-establishment of the data call is completed, the SGSN transmits the data traffic to the data receiving apparatus 150 through the reset path (S331).

4 is a diagram showing a method of driving the SGSN of FIG.

Referring to FIG. 4 together with FIG. 1 and FIG. 2, the SGSN receives location information provided when attempting to access a data call of the terminal 100, and transmits the received location information and subscriber information (Step S401). [0052] In step S401,

To this end, the SGSN provides location information to the HLR, for example, and receives subscriber information based on location information, for example, supplementary service information and a result of whether or not the terminal 100 is subscribed to a specific supplementary service. In addition, a part or all of the location information and the subscriber information may be provided to the data path management server 140 to receive a determination result as to whether a data call connection attempt of the terminal 100 is made in the service zone. Thereafter, the determination result may be separately stored in the memory unit 210.

Then, the SGSN selects a path for data traffic transmission according to the determination result, and transmits the data traffic to the selected path (S403). Here, the path may be one of an Internet and an intranet constituting the supplementary service network 130. If the SGSN is interworking with the GGSN, the decision result may be provided to the GGSN and the GGSN may select the path. At this time, the path selection may be performed by, for example, a method in which the gateway of the intranet uses the source IP addressed to the corresponding data traffic in the GGSN to check the source IP and open or block the route.

In the process of transmitting the data traffic, if the UE 100 moves between the NodeBs, the SGSN can receive the changed location information from the RNC, for example, (S405). ≪ / RTI > In this process, the subscriber information is received from the HLR according to the changed location information, and a part or all of the received location information and subscriber information is provided to the data path management server 140 to receive the re-determination result.

Thereafter, the SGSN compares the received re-determination result with the previously stored determination result in the memory unit 210 (S407). In this case, if the service zone has sector information that is divided into a plurality of sectors, it may be the case that only one of the information on a plurality of sectors coincides with each other.

If the determination result and the re-determination result do not match, the SGSN terminates the currently connected data session and changes or resets the selected data traffic transmission path (S409). More precisely, a change or reset is requested to the GGSN.

If the GGSN changes the selected path, the SGSN transmits the data traffic of the terminal 100 to the changed path (S411).

On the other hand, if the results of the determination and the re-determination match each other, the SGSN maintains the currently connected data session and continues to transmit the data traffic to the selected path (S413).

FIG. 5 is a diagram illustrating a structure of a data service apparatus according to a second embodiment of the present invention, and FIG. 6 is a diagram illustrating a structure of the client module of FIG.

5 and 6, the data service apparatus according to the second embodiment of the present invention includes a communication network 520 including a network device such as an MSC or an SGSN, and a data path management server 540. The data service apparatus may further include a part or all of the terminal 500 including the client module 500a, the AP 510, the additional service network 530, and the data receiving apparatus 550. [ Here, the client module 500a may be variously modified in the form of an IC, a USIM, a SIM card, or the like.

In contrast to the first embodiment of the present invention, the second embodiment of the present invention differs from the first embodiment of the present invention in that when a position change between nodes of a terminal 500 attempting to access a data call occurs, The client module 500a of the terminal 500 detects that the location change has occurred and can determine the maintenance and termination of the data session being accessed. In other words, in the first embodiment, if the RNC provides the changed location information of the terminal 100 to the SGSN, the SGSN uses the changed location information to determine whether the location is within the service zone provided by the data path management server 140 In the second embodiment, the terminal 500 manages the maintenance or termination of the data session itself, while managing the maintenance or termination of the data session being connected using the determination result.

To this end, the terminal 500 may include a memory unit 600 and a data session management unit 610 as shown in FIG. Here, the memory unit 600 may be various information such as key information and base station cell ID to be given when a company subscribes to a specific supplementary service. When the location change of the terminal 500 occurs, the data session management unit 610 compares the currently connected node or base station information provided by the modem or the like with the comparison information stored in the memory unit 600, And can manage the maintenance and termination of the data session during the connection. For example, if the data session management unit 610 provides the comparison result to the control unit (not shown) as a control signal of 0 or 1, the control unit can determine the control signal and maintain or terminate the data session. If the current data session is terminated, the control unit of the terminal 500 may then provide the changed location information to the communication network 520, for example, the SGSN to reset the path for transmitting the data traffic.

In consideration of this point, the second embodiment of the present invention does not specifically require a structural change of the RNC and the SGSN constituting the communication network 120 as in the first embodiment shown in FIGS. 1 and 2 .

Accordingly, the AP 510, the communication network 520, the additional service network 530, the data path management server 540, and the data receiving apparatus 550 according to the second embodiment of the present invention are similar to the first embodiment The data path management server 140 and the data receiving apparatus 150 according to the contents of the AP 110, the communication network 120, the additional service network 130, the data path management server 140, and the data receiving apparatus 150, The description will be omitted.

7 is a diagram illustrating a service process of a data service apparatus according to a second embodiment of the present invention shown in FIG.

Referring to FIG. 7, the data service apparatus according to the second embodiment of the present invention selects a path for transmitting data traffic according to location information provided when a data call connection of the terminal 500 is attempted, And performs a process for transmitting data traffic to the selected path (S701 to S717). This process is substantially the same as that described in the first embodiment of the present invention with reference to FIG. 3, and therefore, the detailed description thereof will be omitted.

When the mobile terminal 500 moves between the nodes or the base stations, the client module 500a, which the mobile terminal 500 itself has, activates and manages maintenance and termination of the currently connected data session (S719). Here, the management is provided at the time of subscription to a specific supplementary service of the terminal 500, and the comparison information related to the service zone stored in the memory unit 600 and the node or base station information received when the terminal 500 moves between the node or the base station It is determined whether or not they match with each other, and management is performed to maintain or terminate the data session being accessed according to the determination result.

If they do not coincide with each other, the terminal 500 terminates the data session being connected and simultaneously transmits the changed location information to the SGSN (S721).

The SGSN transfers the received changed location information to the HLR, for example, and receives the result of subscriber information and additional service subscription provided by the HLR, and then transmits the changed DP information to the data path management server 540 (S723).

Then, the data path management server 540 re-determines whether it is located in the service zone according to the changed DP information (S725), and provides the re-determination result to the SGSN (S727). Then, the SGSN uses the re- A call resetting process is performed (S729). Here, the re-setting may mean that the GGSN changes the path of the Internet and the intranet in the additional service network 530, or modifies the originating IP of the data traffic.

When the path for transmitting the data traffic is changed, the SGSN transmits the data traffic provided by the terminal 500 to the data receiving apparatus 550 through the changed path (S731).

8 is a diagram showing a driving method of the terminal of FIG.

Referring to FIG. 8 together with FIG. 5, the terminal 500 provides location information of a data call connection attempt to the communication network 520 and transmits data traffic to the established route (S801). Here, the path to be set means the Internet or an intranet selected in the supplementary service network 530 depending on whether a data call attempted by the terminal 500 is made within a service zone in which a specific supplementary service is available.

The terminal 500 compares the changed location information of the terminal 500 with the service zone information such as the key information or the base station information related to the service zone provided at the time of subscription service of the terminal 500 And determines whether the currently connected data session is maintained or terminated (S803).

If they do not match, the terminal 500 ends the data session being connected (S805), provides the changed location information to the communication network 520 to reset the path for transmitting the data traffic, (S807).

If the terminal 500 provides the changed location information to the SGSN, the SGSN transfers the changed location information to the HLR to receive the subscriber information including the result of the subscription to the supplementary service , The changed location information, and the subscriber information to the data path management server 540. The data path management server 540 receives a result of the re-determination as to whether or not it is located in the service zone from the data path management server 540, And the Internet and intranet of the network 530 are selected. At this time, the SGSN may provide a re-determination result to the GGSN so that the GGSN may select the route.

On the other hand, if there is a match, the terminal 500 can continue to transmit the data traffic to the first selected path by maintaining the connected data session (S809).

As a result, according to the second embodiment of the present invention, it is possible to appropriately control the right to use a service for a specific supplementary service without increasing a load that may occur in a network device constituting the communication network 520 .
