The private network service registration system according to an embodiment of the present invention includes a mobile terminal 100 that receives a private network service through a network, and a private network service registration server 500 that receives a private network service registration request and registers a private network service. Include.

Here, the network includes various types of mobile communication networks and external networks other than the mobile communication network, for example, the Internet. The mobile communication network may include, for example, a base station, a base station controller, a switch, a home location register, a gateway with an external network, and the like to provide a mobile communication service to the mobile terminal 100.

The mobile terminal 100 mounts a smart card in which information on whether the user of the mobile terminal is a private network service subscriber is stored. Hereinafter, in the present specification, it is assumed that the smart card mounted in the mobile terminal 100 is a universal integrated chip card (UICC). In addition, if the subscriber information of the mobile terminal 100 is stored, it can be applied to all the same.

For example, the mobile terminal 100 may be a mobile phone, a PDA, a notebook, or the like, and any other communication device capable of mounting a UICC may be equally applied.

The UICC 200 is embedded in the mobile terminal 100 or combined in an external form, and stores various information for user authentication and various additional services of the mobile terminal 100.

In addition, the UICC 200 stores a profile (EF: element file) according to a private network connection of the mobile terminal 100. For example, if the mobile terminal 100 requests a private network service registration and then a corresponding acknowledgment message is received, the mobile terminal 100 sets the private network indicator parameter in the profile to a first bit value (eg, “ 1 ") to save.

For example, when the mobile terminal 100 sets the private network indicator parameter to the first bit value (for example, '1'), the mobile terminal 100 provides the mobile terminal 100 to the user through the user interface. It may be displayed that the private network service capable terminal.

In addition, when the mobile terminal 100 boots, for example, referring to the EFKTF_NZONE profile in the UICC card, when the upper 4th bit of the private network indicator (1Byte) in the profile is set to "1", the private network It may be displayed that the service is a terminal.

In addition, when the private network service is released from the corresponding menu of the mobile terminal 100, the upper 4th bit of the private network indicator (1Byte) in the profile may be set to "0" with reference to the EFKTF_NZONE profile.

2 is a network diagram illustrating a private network recognition method according to an embodiment of the present invention.

A private network according to an embodiment of the present invention is composed of two routing areas (RAs) in one location area (LA). Here, the LAs and RAs are areas identified for mobility management of the mobile terminal 100, and the number of LAs and RAs constituting the private network may vary according to a mobile communication environment such as regional characteristics and the number of installed mobile communication devices. have.

LA is defined as an area in which a mobile terminal 100 can move without performing a location update in a circuit service (CS) domain of a WCDMA core network. The LA 310 is composed of cells and may be at least one cell and all cells belonging to at least one visitor location register (VLR). When the mobile terminal 100 performs location registration, the location of the mobile communication terminal 200 is registered in the visitor location register VLR up to the exact LA level.

RA is defined as a region in which the mobile terminal 100 can move without performing location update in the WCDMA core network PS domain. On the other hand, RA is a subset of LA. For example, one LA may have several RAs, but vice versa, and one RA may not have two LAs.

 When the mobile terminal 100 enters the private network from the public network or enters the private network from the public network, the mobile terminal 100 updates its location in the mobile communication system.

In addition, the mobile terminal 100 updates the location when the power is turned on for the first time in the private network, and updates the location when the mobile terminal 100 moves to another RA by moving in the private network area. The method of updating the location of the mobile terminal 100 when moving from a private network to a public network, a private network boundary area, a public network boundary area, or a public network to a private network is obvious to those skilled in the art, and thus a separate description thereof will be omitted.

3 is a block diagram illustrating internal components of a mobile terminal capable of accessing a private network according to an embodiment of the present invention.

Referring to FIG. 3, the mobile terminal 100 includes a transceiver 310, an input unit 315, an audio input unit 320, an audio output unit 325, a display unit 330, a storage unit 335, and a controller ( 340).

The transceiver 310 is operated by the controller 255 and performs a function of transmitting and receiving data with other terminals or devices through a communication network.

For example, the mobile terminal 100 may receive a location registration approval message from the communication network and output the received location registration approval message to the controller 340. Here, the location registration approval message may be system information (SIB type 3: system information block type 3) or an active set update message. Hereinafter, the location registration approval message will be described as a system information or an active configuration update message.

The input unit 315 is a means for receiving various control commands for controlling the operation of the mobile terminal 100 from the user. For example, the input unit 315 may be implemented as a plurality of key buttons (for example, numeric / character keys, * or # symbol keys, and one or more function keys (for example, menu keys, call keys, confirmation keys, etc.). It may be implemented in the form of a touch screen or the like.

The sound input unit 320 may start or end an operation under the control of the controller 340, and is a means for receiving sound from the outside. For example, the sound input unit 320 may be a microphone.

The sound output unit 325 is a means for outputting the sound stored in the storage unit 335 of the mobile terminal 100, the sound received through the transceiver 310, and the like. For example, the sound output unit 325 may include a sound source chip (for example, a Yamaha sound source chip) and may be, for example, a speaker.

The display 330 performs a function of displaying data by at least one combination of image data, image data, text data, and numeric data under the control of the controller 340. For example, the display unit 330 may be a liquid crystal display (LCD).

The storage unit 335 stores the data (for example, data based on one or more combinations of numbers, text, and image data) received through the transceiver 310 under the control of the controller 340, and the mobile terminal 100. An operating program for operating, a preset algorithm, and the like are stored.

The controller 340 is an internal component of the mobile terminal 100 according to an embodiment of the present invention (for example, the transceiver 310, the input unit 315, the sound input unit 320, the sound output unit 325 ), The display unit 330, the storage unit 335, etc.).

In addition, the controller 340 analyzes the system information or the active configuration update message inputted through the transceiver 310 to determine whether the mobile terminal 100 has left the private network. If it is determined that the mobile terminal 100 has left the private network, the controller 340 may terminate the communication call.

For example, the controller 340 extracts the cell identification field Cell_ID from the system information or the active configuration update message, and determines whether the upper 15th bit value is the first bit value (eg, '0'). . If the upper 15th bit value is the first bit value, the controller 340 determines that the mobile terminal 100 leaves the private network, moves to the public network, and performs a communication call. .

Here, the controller 340 extracts an end guide message (the end guide message may be any one of voice, video, and text) stored in advance in the storage unit 335 and transmits it to the called terminal through the transceiver 310. Can be. For this reason, the receiving terminal can be informed in advance of the reason for the end of the communication call according to the forced termination of the communication call of the mobile terminal 100 so as to eliminate misunderstanding of the user corresponding to the called terminal.

In addition, the mobile terminal 100 generates a location registration message or a location update message and outputs the location registration message or the location update message to the switch 400 through the communication network when the mobile terminal 100 is located in the boundary area of the private network or the public network. Accordingly, the exchange 400 may analyze the location registration message or the location update message to determine whether the mobile terminal 100 has left the private network to terminate the communication call in progress or to start charging. This will be described in detail with reference to the accompanying drawings below.

4 is a block diagram illustrating an internal functional configuration of an exchange according to an embodiment of the present invention. Hereinafter, in the present specification, it is assumed that the switch 400 is a switch of the mobile communication system, and this will be described with emphasis. However, the exchange 400 may be equally applicable to a device capable of forcibly terminating a communication call or initiating charging when the mobile terminal 100 leaves the private network. Hereinafter, the mobile terminal 100 will be described with an emphasis on the assumption that the mobile terminal 100 is an originating terminal that is attempting to communicate or accesses a communication call. However, the mobile terminal 100 may be a called terminal.

As shown in FIG. 4, the switch 400 includes a data transceiver 410, a storage 415, and a controller 420.

The data transceiver 410 transmits and receives data to and from the mobile terminal 100 and another device (for example, a billing server (not shown)) through a communication network.

For example, the data transceiver 410 may receive a location registration message or a location update message from the mobile terminal 100 and output the received location registration message or the location update message to the controller 420. In addition, the data transceiver 410 may transmit a communication termination notification message or a charging start notification message to the mobile terminal 100 or the called terminal through a communication network under the control of the controller 420.

The storage unit 415 stores an algorithm, a program, data received through a data transceiver, and the like, for operating the switch 400 according to the present invention.

The controller 420 controls the internal components of the switch 400 according to the present invention (eg, the data transceiver 410, the storage 415, etc.). In addition, the controller 420 analyzes the location registration message or the location update message received from the mobile terminal 100 to determine whether the mobile terminal 100 has left the private network during the communication call connection attempt or during the communication call connection. . If it is determined that the private network has left, the controller 420 may control the mobile terminal 100 to terminate the communication call.

For another example, the controller 420 may transmit a charging start notification message to the mobile terminal 100 for the mobile terminal 100 that has left the private network, and then generate charging information and transmit the charging information to the charging server (not shown). .

5 is a flowchart illustrating a method of terminating a communication call being performed by a mobile terminal when leaving a private network according to an embodiment of the present invention. Hereinafter, the mobile terminal 100 will be described based on the assumption that the mobile terminal 100 is an originating terminal that is attempting to communicate or accesses a communication call.

In operation 510, the mobile terminal 100 receives system information (eg, SIB type 3) or an active configuration update message from the exchange 400.

In step 515, the mobile terminal 100 analyzes the system information or the active configuration update message to determine whether the mobile terminal 100 has left the private network.

For example, the mobile terminal 100 may extract the cell identification field Cell_ID from the system information or the active configuration update message, and then determine whether the lower 15th bit value of the cell identification field is the first bit value. If the lower 15th bit value of the cell identification field is the first bit value (eg, '0'), the mobile terminal 100 may determine that the mobile terminal 100 has left the private network.

However, if the lower 15th bit value of the cell identification field is the second bit value (eg, '1'), the mobile terminal 100 may recognize that the mobile terminal 100 is located in the private network.

If it is determined that the private network has left, the mobile terminal 100 reads a preset communication call termination guide message from the storage unit 335 and transmits the preset communication call termination message to the called terminal through the communication network. This allows the user of the called terminal to know the end of the communication call in advance to prevent unnecessary misunderstandings.

In step 525, the mobile terminal 100 forcibly terminates the communication call.

However, if the private network does not leave the mobile terminal 100 in step 530 performs a normal communication call.

6 is a flowchart illustrating a method of controlling a communication call of a mobile terminal in an exchange according to an embodiment of the present invention. Hereinafter, the mobile terminal 100 will be described based on the assumption that the mobile terminal 100 is an originating terminal that is attempting to communicate or accesses a communication call and is a terminal that can access a private network.

In operation 610, the switch 400 receives a location registration message or a location update message from the mobile terminal 100.

As described above, the mobile terminal 100 generates and transmits a location update message when moving from a private network to a public network or when moving from a public network to a private network. In addition, when power is applied to the mobile terminal 100, the mobile terminal 100 may generate and transmit a location registration message.

In step 615, the switch 400 analyzes the location registration message or the location update message to determine whether the mobile terminal 100 has left the private network.

If it is determined that the private network has left, the switch 400 transmits a preset guide message (for example, a guide message for terminating a communication call) to the mobile terminal 100 and the called terminal, respectively.

In operation 625, the switch 400 forcibly terminates the communication call (that is, the communication call being performed) of the mobile terminal 100.

However, if the private network does not leave, the communication call is performed according to the conventional method.

For another example, the exchange 400 analyzes the location registration message or location update message received from the mobile terminal 100 and determines that the mobile terminal 100 has left the private network. 100). In addition, the exchange 400 may generate charging information and transmit the charging information to a charging server (not shown). For this reason, when the mobile terminal 100 leaves the private network, charging may be performed.
