The present invention relates to a wireless communication method and system for outbound roaming service, and in particular, a mobile terminal having the same mobile subscriber as a domestic Wideband Code Division Multiple Access (WCDMA), etc. It is possible to block individual service for each domain by avoiding global subscription and cancellation of CS (Circuit Switch) and PS (Packet Switch) domains in the overseas roaming service, which allows domestic mobile communication services to be continuously used in foreign countries. Thus, a CS service using a circuit channel such as a voice call or a video call and a PS service using a data (packet) channel such as downloading / uploading or uploading multimedia data or wireless Internet connection can be freely selected to receive overseas roaming service. It relates to a communication method and system.

Today, according to the overseas roaming service, mobile communication subscribers such as domestic WCDMA can use various mobile communication services by accessing domestic communication networks in foreign countries using the same mobile terminal. Generally, subscribers would like to use voice or video call service through mobile terminals, but the functions of mobile terminals have been extended to receive download / upload service of multimedia data or wireless internet service.

Domestic mobile subscribers have to pay expensive fees to receive overseas roaming services. Depending on the charging policy of the mobile operator, the charging policy of the call service and data service is generally different. In cases where the fees for the CS service and the PS service are different, for example, if the CS service is charged less than the PS service, or vice versa, the subscriber may also wish to use only relatively low cost services. have. Alternatively, some subscribers of roaming services may wish to use only CS services such as voice and video calls in foreign countries, as well as PS services such as downloading / uploading multimedia data or wireless Internet access, depending on their personal and business purposes. There is a case to use.

However, when roaming outbound overseas, there are currently no individual subscriptions or cancellations for CS and PS domains. Accordingly, subscribers receive overseas roaming services by subscribing to the entire CS and PS domains, and when a mobile terminal that does not subscribe to such overseas roaming services attempts to roam in the CS or PS domains, the subscriber receives 'HLR (Home Location Register)'. roaming not allowed '. Currently, in domestic mobile communication, CS and PS domains can be individually subscribed, but overseas roaming services can freely select either CS service or PS service to receive individual services, so they can be freely selected according to the user's choice. It is required to provide overseas roaming service to be able to subscribe and cancel as an option.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to download / upload a multimedia service or a wireless Internet connection using a CS service such as a voice call or a video call in an outbound overseas roaming service. In order to allow PS service using a data (packet) channel such as to be freely selected to receive overseas roaming service, the location registration method that can block individual service for each domain is avoided by avoiding overall subscription and cancellation of CS and PS domains. The present invention provides a wireless communication method and system.

If the registration is characterized in that for updating the location registration for the terminal.

When the CS subscriber roaming block is registered in the CS domain, an error message indicating a non-subscriber to the MS is notified to the MSV belonging to an overseas network through the GLR, and the location registration update is rejected. When the roaming block of the PS domain is registered, the UE may notify the SGSN of the foreign network through the GLR to the error message and reject the location registration update.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited to the embodiments. Like reference numerals in the drawings denote like elements.

1 is a view for explaining a wireless communication system 100 according to an embodiment of the present invention. Referring to FIG. 1, a wireless communication system 100 according to an embodiment of the present invention includes a core network 110, a radio access network (RAN) 120, and a mobile station. : MS) 130, Gateway Location Register (GLR) 140, Home Location Register (HLR) 150, Mobile Terminal 160, and Application Server 170.

Wireless communication system 100 according to an embodiment of the present invention is configured to provide an outbound overseas roaming service, accordingly mobile subscribers such as domestic Wideband Code Division Multiple Access (WCDMA) that has departed overseas The mobile terminal 130 may continue to use a mobile communication service provided in a domestic home network in an overseas visitor network.

Here, the overseas visitor network and the home network are a service of a CS (Circuit Switch) domain such as a voice or video call service based on a circuit channel and a download or upload of multimedia data based on a data channel, a wireless Internet service, or a portable network. It is assumed that a service of a packet switch (PS) domain such as an Internet service can be provided to the mobile terminals 130/160. Such mobile communication services are provided based on WCDMA as shown in FIG. 1, which will be described below by way of example. However, the present invention is not limited thereto, and according to the mobile communication environment of each overseas or home network, GSM (Global System for Mobile Communications) , IMT2000, CDMA2000, and the like.

The core network 110 includes both an public network connecting a circuit channel or an internet network connecting a data channel, and may also include a portable internet network.

The RAN 120 is composed of a base station (Node-B) and a Radio Network Controller (RNC). The base station Node-B connected to the RNC may be configured in plural, and the mobile terminal 130 receives a relay of the base station Node-B to provide communication services such as call, digital broadcasting, digital media streaming, download and upload. I can receive it. The RNC connected between the base station Node-B and the core network 110 controls the traffic generated in the communication to be transmitted and received to the destination through the base station Node-B. The RNC performs a radio resource management (RRM) function according to scheduling of radio resources and a handoff function for supporting cell-to-cell mobility to control communication between the mobile terminals 130 so that circuit traffic of the CS domain can be achieved. traffic or IP (Internet protocol) packet traffic of the PS domain can be appropriately transmitted and received to the destination mobile terminal, wireline, application server, etc. of the location.

Although not shown in FIG. 1, similar configurations such as the core network 110 and the RAN 120 are also included in the home network, and the mobile terminal 130 of the overseas network and the mobile terminal 160 of the home network according to the network. The CS domain service may be provided between the mobile station 130 and the mobile terminal 130 of the overseas network. The service of the PS domain operated by the application server 170 may be used.

The mobile terminal 130/160 may be a cellular phone, a personal communications services phone (PCS phone), a synchronous / asynchronous international mobile telecommunication-2000 (IMT-2000) terminal, Notebook PCs, desktop PCs, Palm Personal Computers, Personal Digital Assistants (PDAs), Smartphones, WAP phones (Wireless application protocol phones), It means all communication devices such as mobile play-station.

The mobile switching center server (MSV) 111 of the core network 110 is a switch that provides a subscriber line switching service during call processing of a CS domain such as voice call, video call, and SMS transmission. It exists as an MSV and can support a handoff function that supports mobility between cells. The mobile terminal 130 may register its location with the HLR 150 through communication with the MSV 111 to receive the service of the CS domain in any region, and may use the nearest Location Location (VLR) visitor of the nearest MSC. Location register) manages the information of the subscriber station received from the HLR (150).

The Serving GPRS Service Node (SGSN) 112 of the core network 110 is a PS domain of a General Packet Radio Service (GPRS) network, such as downloading or uploading multimedia data, a wireless Internet service, or a mobile Internet service. Control the call handling of the service. The mobile terminal 130 may register its location in the HLR 150 through communication with the SGSN 112 in order to receive the service of the PS domain in any region, and the predetermined location registration means of the nearest SGSN 112. The information of the subscriber station received from the HLR 150 can be managed. Although not shown in FIG. 1, a Gateway Packet Radio Service (GGSN) may be further included for communicating with an Internet network in cooperation with SGSN 112 for call processing of a PS domain service.

Based on the core network 110 as described above, the mobile terminal 130 of the overseas network may perform a location registration process with the HLR 150 of the home network through the GLR 140 in a visited network of each country that has subscribed to an overseas roaming service. Accordingly, the HLR 150 not only manages the location registration and status of the mobile terminals 160 of the home network, but also manages the real time location registration and status of the mobile terminals 130 of the overseas network. Various mobile communication services of the CS and PS domains that are operated may be naturally provided to the mobile terminal 130 of the overseas network.

The GLR 140 manages real-time location information and status of an overseas roaming terminal through a predetermined communication network connecting a mobile communication system between countries, between an overseas visited network and a home network to provide an overseas roaming service. The GLR 140 may relay the location information of the mobile terminal 130 of the overseas network, the information of the subscriber terminal, etc. to be transmitted to the HLR 150 of the home network at the time of location registration. The GLR 140 may be operated in a home network and a visited room, respectively. Here, the GLR 140 is described as one system configured to transmit and receive necessary signals or messages through a predetermined communication network connecting countries.

In the present invention, in particular, in order to provide an outbound roaming service between the overseas network and the home network, the HLR 150 registers individual locations for each of the CS domain and the PS domain in the home network with respect to the mobile terminal 130 of the overseas network. You can run databases for each and update the location registration of the domain in each database. Accordingly, when the HLR 150 updates the location registration for the CS domain, the service subscriber of the CS domain may be managed to provide a service for only the CS domain except the PS domain to the mobile terminal 130 in the home network. have. In addition, when the HLR 150 updates the location registration for the PS domain, the service subscriber of the PS domain may be managed to provide a service for only the PS domain except for the CS domain to the mobile terminal 130 in the home network. .

For example, when the mobile terminal 130 of the overseas network generates a request message for location registration update for the CS domain or the PS domain, the MSV 111 or SGSN 112 belonging to the overseas network according to the request message When generating a registration notification message (Update Location / Update GPRS Location) for the domain, the GLR 140 receives the registration notification message generated by the MSV 111 or SGSN 112 and transmits it to the HLR 150. Done.

When roaming blocking of the corresponding domain for the mobile terminal 130 is registered in each database of the HLR 150, when a request for updating the location registration from the mobile terminal 130 is received, the HLR 150 is 'Unknown'. It generates an error message indicating an unsubscriber such as Subscriber '(Unknown_Sub), and notifies the MSV 111 or SGSN 112 belonging to the foreign network through the GLR 140 and rejects the location registration update for the domain. .

Conventionally, for overseas roaming services, when the mobile terminal 130 of the overseas network that is not joined due to the overall subscription and cancellation of the CS and PS domains performs a location registration process in the CS or PS domain, the HLR 150 is an overseas network. 'Roaming Not Allowed' was notified.

However, in the present invention, the CS and PS domains can be registered separately from the overseas roaming service as described above. Thus, CS services using line channels such as voice calls or video calls, download / upload of multimedia data, and wireless Internet access can be registered. PS service using a data (packet) channel, such as a portable Internet connection, can be freely selected. Accordingly, the overseas roaming service according to the present invention can increase the convenience of the overseas roaming user according to the individual blocking of the CS and PS services, thereby contributing to the activation of the overseas roaming service.

HLR 150 according to an embodiment of the present invention may be configured as shown in FIG. 2, an HLR 150 according to an embodiment of the present invention may include a CS subscriber management unit 151, a CS subscriber DB 152, a PS subscriber management unit 153, and a PS subscriber DB 154. Can be.

The CS subscriber management unit 151 and the PS subscriber management unit 153 register a registration notification message (Update Location / Update GPRS Location) through the GLR 140 according to a request message for location registration update generated from the mobile terminal 130 of the overseas network. ). The registration notification message is a message generated by the MSV 111 or SGSN 112 for the location registration notification for the domain when the mobile terminal 130 generates the request message for the CS domain or the PS domain. When the mobile terminal 130 generates a request message for updating the location registration for the CS domain, the MSV 111 generates a corresponding registration notification message (Update Location), which is controlled by the CS subscriber management unit (GLR 140). 151 and the PS subscriber management unit 153 are notified. In addition, when the mobile terminal 130 generates a request message for location registration update for the PS domain, the SGSN 112 generates a corresponding registration notification message (Update GPRS Location), which is a CS subscriber through the GLR 140. The manager 151 and the PS subscriber manager 153 are notified. The request information for the location registration update generated by the mobile terminal 130 and the registration notification message (Update Location / Update GPRS Location) generated by the MSV 111 or the SGSN 112 include the terminal information of the mobile terminal 130 and the current information. ID information of the nearest cell (base station), which is location information, is included.

As such, when the CS subscriber management unit 151 and the PS subscriber management unit 153 receive the registration notification message (Update Location / Update GPRS Location) through the GLR 140, the CS subscriber management unit 151 is in response to the registration notification message. Accordingly, it is determined whether the roaming subscription of the CS domain for the mobile terminal 130 is registered in the CS subscriber DB 152, and the PS subscriber management unit 153 according to the registration notification message, the PS domain for the mobile terminal 130 It is determined whether the roaming subscription of is registered in the PS subscriber DB (154).

The CS subscriber DB 152 stores and manages the information of the roaming subscriber station, which receives a service for the CS domain only from the home network, except for the PS domain when roaming abroad. The PS subscriber DB 154 stores and manages information of roaming subscriber stations that receive services from the home network only for the PS domain except the CS domain when roaming overseas. The information of the subscriber station includes terminal-specific information such as subscriber name and terminal number corresponding to each terminal, additional service subscription information, and the like, and also includes registration details for roaming subscription and blocking. In addition, the CS subscriber DB 152 and the PS subscriber DB 154 stores and manages real-time location information and states (power state, call availability state, etc.) of each roaming terminal.

On the other hand, when the CS subscriber management unit 151 receives the registration notification message through the GLR 140 as described above, when the roaming subscription of the CS domain with respect to the mobile terminal 130 is registered in the CS subscriber DB 152. The location registration for the mobile terminal 130 may be updated in the CS subscriber DB 152. In addition, when the PS subscriber management unit 153 receives the registration notification message through the GLR 140 as described above, when the roaming subscription of the PS domain for the mobile terminal 130 is registered in the PS subscriber DB 154. The location registration for the mobile terminal 130 may be updated in the PS subscriber DB 154. The location information of the mobile terminal 130 updated as described above may be notified to the MSV 111 and SGSN 112, and may also be notified to the mobile terminal 130.

However, the CS subscriber management unit 151 is not known to the mobile terminal 130 when the roaming blocking of the CS domain for the mobile terminal 130 is registered (in the case of domestic subscription but no overseas CS service subscription). An error message indicating an unsubscriber is generated, such as '(Unknown_Sub)', and is notified to the MSV 111 belonging to the foreign network through the GLR 140, and the location registration update is rejected. In addition, the PS subscriber management unit 153 determines that the roaming blocking of the PS domain for the mobile terminal 130 is registered (in the case of domestic subscription but no overseas PS service subscription). It generates an error message indicating a non-subscriber, such as' and informs the SGSN 112 belonging to the foreign network through the GLR 140 and rejects the location registration update.

As described above, in the present invention, in providing a roaming service between an overseas network and a home network, an individual location registration for each of the CS domain and the PS domain in the home network can be updated for the mobile terminal 130 of the overseas network. . Accordingly, when the CS subscriber management unit 151 updates the location registration for the CS domain, the mobile terminal 130 of the overseas network may provide a service for only the CS domain except for the PS domain operated in the home network. In addition, when the PS subscriber management unit 153 updates the location registration for the PS domain, the mobile terminal 130 of the overseas network may provide a service for only the PS domain except for the CS domain operated in the home network. It becomes possible.

Hereinafter, the operation of the wireless communication system 100 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 3 and 4.

3 is a flowchart illustrating an operation when a terminal registered with roaming blocking of a CS or PS domain performs location registration in the wireless communication system 100 according to an embodiment of the present invention.

First, a customer management system (e.g., WISE) or an HLR 150 operator (e.g., OAM), such as a mobile telecommunications agency, is responsible for the CS subscriber DB 152 of the HLR 150 for each subscriber station of domestic mobile communication. Alternatively, the PS subscriber DB 154 may register or block overseas roaming (S31).

In order to use an overseas roaming service in an overseas visit network, the mobile terminal 130 may generate a request message for location registration update for the CS domain or a request message for location registration update for the PS domain (S32). .

When the mobile terminal 130 generates a request message for updating the location registration for the CS domain, the MSV 111 generates a corresponding registration notification message (Update Location) (S33), which is an HLR through the GLR 140. The CS subscriber manager 151 and the PS subscriber manager 153 of 150 are notified (S34). Alternatively, when the mobile terminal 130 generates a request message for updating the location registration for the PS domain, the SGSN 112 generates a corresponding registration notification message (Update GPRS Location) (S33), which is a GLR 140. The CS subscriber management unit 151 and the PS subscriber management unit 153 are notified (S34). The registration notification message notified to the HLR 150 may include terminal information of the mobile terminal 130 and ID information of the nearest cell (base station) which is current location information.

At this time, when the HLR 150 receives the registration notification message as described above, the location registration deletion message is transmitted to the previous MSV 111 or SGSN 112 through a predetermined control means to prepare for updating the previous location information ( S35). At this time, if the registration notification message as described above is generated from the MSV 111, the HLR 150 may communicate with the previous MSV 111 to perform the location registration deletion process, the registration notification message as described above SGSN 112 If generated from, the HLR 150 may communicate with the previous SGSN 112 to perform a location registration deletion process.

On the other hand, when the CS subscriber management unit 151 and the PS subscriber management unit 153 receives the above registration notification message through the GLR 140, the CS subscriber management unit 151 according to the registration notification message, the mobile terminal 130 It is determined whether roaming subscription / blocking of the CS domain is registered in the CS subscriber DB 152, and the PS subscriber management unit 153 according to the registration notification message, the roaming subscription / blocking of the PS domain for the mobile terminal 130. It is determined whether the blocking is registered in the PS subscriber DB 154 (S36).

Accordingly, when it is determined that roaming blocking of the CS or PS domain for the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, the location registration rejection including steps S37 to S39 is rejected. The process can be performed.

For example, when the CS subscriber management unit 151 determines that roaming blocking of the CS domain for the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, the mobile terminal 130 is registered. Set the 'Purge MS' with respect to (S37). That is, the CS subscriber management unit 151 generates an error message indicating an unsubscriber such as 'Unknown Subscriber', notifies the MSV 111 belonging to the overseas network through the GLR 140 and rejects the location registration update (S38). ). Such a rejection response may also be notified to the mobile terminal 130 (S39).

Similarly, if the PS subscriber management unit 153 determines that roaming blocking of the PS domain for the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, 'Purge MS' is set (S37). That is, the PS subscriber management unit 153 generates an error message indicating an unsubscriber such as 'Unknown Subscriber', notifies the SGSN 112 belonging to the overseas network through the GLR 140 and rejects the location registration update (S38). ). Similarly, such a rejection response may be notified to the mobile terminal 130 (S39).

Meanwhile, when it is determined that the roaming subscription of the CS or PS domain for the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, the location registration update process including steps S40 to S42. This can be done.

If the HLR 150 determines that roaming subscription of the CS or PS domain is registered in step S36, the information (ISD) of the subscriber station of the mobile terminal 130 to the MSV 111 or SGSN 112 through a predetermined control means. By transmitting the control also to manage the subscriber-related information in the system (S40).

Further, for example, when the CS subscriber management unit 151 determines that roaming subscription of the CS domain with respect to the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, the mobile terminal The registration for the current location of 130 may be updated in the CS subscriber DB 152 (S41). The location information of the mobile terminal 130 updated as described above may be notified to the MSV 111 and SGSN 112, and may also be notified to the mobile terminal 130 (S42).

In addition, when the PS subscriber management unit 153 determines that the roaming subscription of the PS domain with respect to the mobile terminal 130 is registered according to the registration notification message received through the GLR 140 as described above, The registration for the current location may be updated in the PS subscriber DB 154 (S41). Similarly, the location information of the mobile terminal 130 updated in this way may be notified to the MSV 111 and SGSN 112, and may also be notified to the mobile terminal 130 (S42).

4 is a diagram illustrating a case where there is a block registration for a PS or CS domain for a subscriber who has already subscribed to an overseas roaming service.

For example, while a mobile terminal 130 of a subscriber who is already subscribed to an overseas roaming service for a PS or CS domain is receiving a roaming service through a location registration update as shown in FIG. 3, a customer management system such as a mobile communication agency ( For example, blocking of roaming abroad may be registered in CS subscriber DB 152 or PS subscriber DB 154 of HLR 150 via WISE or HLR 150 operator (eg, OAM). In such a case, the HLR 150 may notify the MSV 111 or SGSN 112 registered in the overseas network through the GLR 140 to delete the location registration for the corresponding domain. At this time, in the case of blocking registration of the overseas roaming service for the CS domain, the location registration deletion process will be performed by communicating with the MSV 111 of the overseas network, and in the case of blocking registration of the overseas roaming service for the PS domain, Communication with the SGSN 112 of the location registration deletion process will be made.

As such, the mobile terminal 130 of the overseas network updates the location registration to the HLR 150 of the home network through the GLR 140 in real time, and the HLR 150 manages the location registration and status of the mobile terminal 130. Thus, the mobile terminal 130 can receive a roaming service in any of the foreign networks. In particular, the mobile terminal 130 registered with the roaming subscription to the CS domain may be provided with a service of the CS domain such as a voice or video call service based on a circuit channel and the like of the mobile terminal 160 of the home network. The mobile terminal 130 registered with a roaming subscription to a domain provides a service of a PS domain such as downloading or uploading multimedia data, wireless Internet service, or mobile Internet service based on a data channel with an application server 170 of a home network.
