Description

[0001] The present invention relates to a virtualization system of a mobile phone using a software-based gateway and a virtualization method of a mobile phone,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a virtualization system of a mobile phone and a virtualization method of the mobile phone, and more particularly, to a virtualization system of a mobile phone that provides a communication service of a virtual mobile phone using a gateway between the virtual mobile phone and the mobile communication network, The present invention relates to a method of virtualizing a telephone.

A technique of virtualizing and driving a mobile phone terminal is used. The virtualization technology of the mobile phone enables the mobile phone terminal to run multiple virtual machines, thereby providing the convenience that the users of the office do not need to own personal or business mobile phones respectively. However, such a mobile phone terminal based virtualization technology has some problems.

First, a physical cellular phone terminal is indispensable. Since the virtualization software and the instances of the virtualized operating system are both operated by the mobile phone terminal, the terminal is indispensable. Second, when a plurality of virtual machines are driven in a mobile phone terminal, a lot of terminal resources are consumed. Considering the host operating system required for a virtualized environment, the virtual environment above, and the guest operating system, a much higher level of memory capacity, computing capacity, and battery capacity are required. Considering that one of the inconveniences of using a mobile phone terminal is a poor hardware environment compared to a PC, a high-specification resource required for a mobile phone terminal is a serious drawback. Third, there is a limitation of scalability. In order to use various mobile OSs in a mobile phone terminal, it is necessary to secure the storage space and install the corresponding mobile OS. Also, whenever a new mobile OS is installed in a mobile phone terminal, upgrading of a related program and resetting of a virtual execution environment may be involved.

In connection with the virtualization technology of the mobile phone, the following patents disclose a technology for building a virtualized mobile phone in a PC. This technology solves the hardware constraint problem of the mobile phone terminal somewhat by constructing a virtual mobile phone in a more powerful PC instead of a mobile phone terminal. However, the above-described technology also requires a PC terminal, consumes resources of the PC terminal, and is dependent on the hardware specification of the PC. In addition, every time a new mobile OS is installed in a PC, the user is accompanied by a series of PC management for setting up the mobile OS and resetting environment information of the upgrade and virtual execution of the related program.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is a schematic configuration diagram of a virtualization system 1 of a cellular phone according to an embodiment of the present invention.

A virtualization system 1 of a cellular phone according to an embodiment of the present invention includes a gateway server 2 and a plurality of user terminals 3 for mediating users' virtual cellular phone 400 to the mobile network 5, And a virtualization server 4 for providing an execution service of the virtual mobile phone to the gateway server 2 to mediate data communication with the gateway server 2.

Here, the virtualization system 1 of the cellular phone includes a user terminal 3 that receives a virtual cell phone execution service from the virtualization server 4, a gateway server 2 and a mobile switching center 520) and a mobile switching center (520) connected to the mobile control station (510) for switching the communication connection of the virtual mobile phone.

The user terminal 3 is a terminal connected to the virtualization server 4 and executing a virtual mobile phone. The user terminal 3 may be any device capable of accessing the Internet via a network such as a computer terminal (e.g., a desktop, a notebook), a smart phone, a tablet PC, a smart TV, And user input tools are included.

Here, the user terminal 3 is remotely connected to the virtualization server 4, and an application for executing the virtual mobile phone is installed. For example, the application is an application that provides a VNC (Virtual Network Computing) function in a general PC environment. In addition, there are a variety of software for remote access from smartphones and tablet PCs.

The virtualization server 4 executes a program of a virtual mobile phone held by users. The virtualization server 4 is building a virtualization environment to run a mobile operating system (e.g., iOS, Android, etc.) used in a virtual portable terminal on a server operating system such as Linux or Unix. The virtualization environment may be a pure software based on Java or a virtualization environment supported by server hardware. Of course, the virtualization server 4 does not depend on a specific implementation method of the virtualization environment, and each virtualization technique according to various environments can be implemented.

Here, the virtualization server 4 provides a daemon process that can interact with the user terminal 3. The daemon process receives the operation data of the virtual mobile phone from the remotely connected user terminal 3 and provides an interface for responding to the processing result to the user terminal 3, Lt; / RTI > The virtualization server 4 provides remote access and control services to the user terminal 3 through the daemon process. In addition, the virtualization server 4 provides voice call data and Internet communication data services through the daemon process. Therefore, if the user terminal 3 serves as a VNC client, the virtualization server 4 serves as a VNC server corresponding to the VNC client. Meanwhile, the virtualization server 4 may require an independent server operating system account for the user connected to the user terminal 3 to execute his / her own virtual portable terminal.

The virtual mobile phone 400 corresponds to a virtual mobile phone terminal as a virtual machine that runs on the memory of the virtualization server 4. [ The virtual mobile phone 400 loads the mobile operating system and performs emulation processing on the user terminal 3. [ Of course, the executed virtual mobile phone 400 includes a basic operating system function such as receiving an input to the user as an actual mobile phone terminal, or outputting a response thereto by using a display, And a function as a telephone terminal such as exchanging data traffic with a mobile network.

Here, the virtual mobile phone 400 stores user subscription information (e.g., a communication company, a telephone number, etc.) of the mobile network in order to perform a function as a telephone terminal. For example, if the virtual mobile phone 400 is connected to a GSM (Global System for Mobile Communications) mobile network, the user subscription information is stored in a virtual mobile phone 400 in the form of a Subscriber Identity Module (SIM). The virtual mobile phone 400 may have a status that is executed according to a command of a user or an operator of the virtualization server 4, temporarily halted execution, or is completely terminated and unloaded from memory.

The gateway server 2 connects the virtual mobile phone 400 executed in the virtualization server 4 to the actual mobile network 5. Since the virtual mobile phone 400 operates as if it is an actual mobile communication terminal, a device functioning as a base station transceiver subsystem (BTS) of the mobile network needs to be connected to the virtual mobile phone 400. Therefore, a software-based BTS (BTS) based on software is installed in the form of a gateway server 2 to perform a mobile station function and a network gateway function on the virtual mobile phone 400. The mobile base station of the gateway server 2 mediates the interconnection between the virtual mobile phone 400 and the mobile network 5. Then, messages and data received via the mobile network 5 are transmitted to the virtual mobile phone 400, and messages and data generated by the virtual mobile phone 400 are transmitted through the mobile network 5. [ Here, the mobile base station of the gateway server 2 is physically connected to the virtualization server 4 and is logically connected to the virtual mobile phone 400.

The BSC 510 is connected to the mobile base station of the gateway server 2 via the mobile network 5. From the standpoint of the mobile network 5, the mobile control station 510 can not distinguish whether the actual physical cell phone is connected or the virtual cell phone is connected. Accordingly, the mobile control station 510 mediates data communication between the mobile base station and the mobile switching center 520 without discrimination between the actual mobile phone and the virtual mobile phone.

The mobile switching center 520 is connected to the mobile control station 510 on the mobile network to store service information of the virtual mobile phone, and switches the communication connection of the virtual mobile phone with reference to the service information. The mobile switching center may also receive data from another mobile switching center 520 to a virtual mobile telephone.

2 is a schematic internal structure diagram of a virtualization system 1 of a cellular phone according to an embodiment of the present invention. 3 is a schematic internal structure diagram of a mobile operating system unit according to an embodiment of the present invention.

2, a user terminal 3 according to an embodiment of the present invention includes a hardware unit 31, an operating system unit 32, and an application 33 of a virtual mobile phone as an internal structure. The hardware unit 31 refers to a processing device, input / output device, display device, or the like of the user terminal. The operating system unit 32 refers to an operating system that controls and manages the devices of the hardware unit 31.

The user terminal 3 remotely accesses the virtualization server 4 to operate the virtual mobile phone 400 driven by the remote virtualization server 4 and remotely commands the virtualization server 4 to respond to the remote command A remote access software (remote access software) for receiving the data of the processing result and outputting the received data to the screen and the speaker is needed. The application 33 is developed on the basis of remote access software for communicating data by operating the virtual mobile phone 400 of the virtualization server 4.

The remote access software typically includes an X-Window, a Remote Desktop, and a VNC Client. However, the present invention is not limited to specific software, and the scope of the technology implementation may be much wider. These software deliver the input from the user to the server, using the protocol specific to each client. X-Window's X.11, and Virtual Network Computing's RFB. Since these protocols are disclosed, it is possible to develop a virtual mobile phone application 33 for their own service. Data transmitted from the application 33 to the virtualization server 4 is processed by a remote access service driven by the virtualization server 4 or a process called a daemon.

Preferably, the virtualization server 4 according to an embodiment of the present invention is installed based on a hardware unit 41 and a hardware unit 41 corresponding to a device that executes a physical operation, and controls the execution of a hardware device A daemon process unit 43 installed on the basis of the operating system unit 42 and the operating system unit 42 and connected to the application 33 to communicate data, a daemon process unit 43, An emulator section 44 for emulating data between the mobile operating system section 45, a mobile operating system section 45 for executing a mobile operating system corresponding to each virtual mobile phone and communicating data with the gateway server 2, And a mobile application unit 46 in which applications of the virtual mobile phone are executed based on the mobile operating system unit 45. [

Here, the virtualization server 4 is located remotely from the user terminal 3 and provides the execution service of the virtual mobile phone to the virtual user terminal 3. The virtualization server 4 establishes an execution environment of each virtual mobile phone for users subscribed to the service of the virtual mobile phone. In the execution environment, the operating system unit 42 is built on the physical hardware unit 41, and a server-side operating system (e.g., Unix, Linux, etc.) is executed. A daemon process unit 43 for mediating data communication with the application 33 of the user terminal 3 is constructed on the operating system unit 42. [ The daemon process unit 43 provides a remote access and control service to the application 33. Here, the daemon process unit 43 activates the service functions based on the operating system unit 42, and if an input from the user is received while it is waiting, the daemon process unit 43 determines which user is the input from the user, Pass that input.

The virtualization server 4 further includes an emulator unit 44 capable of emulating data to the mobile operating system unit 46 installed for each virtual mobile phone 400 in order to execute a plurality of virtual mobile phones 400, Is required. The emulator unit 44 is implemented as a virtual machine to perform data emulation processing. Depending on the type of mobile operating system, there are a variety of virtual machine emulation software that supports it, so that a selected environment can be built in the virtualization server 4 according to the desired mobile operating system. Typical examples are VirtualBox, VMWare, and RTS Hypervisor, which support virtual machine environments. In some cases, a Java Virtual Machine (JVM), for example, may need to be installed on top of such software if necessary. Consequently, the virtualization server 4 establishes execution environments of the daemon process unit 43, the emulator unit 44, and the mobile operating system unit 45 to provide the execution service of the virtual mobile phone 400.

Further, the mobile operating system executed by the mobile operating system unit 45 refers to an operating system currently installed in a smart phone such as iOS, Android, and the like. The mobile operating system is executed in the virtual environment described above, and information necessary for connection with the actual mobile network 5 is internally set. For example, as the mobile subscriber information and the key value for authentication are stored in the SIM in the mobile phone terminal, the mobile operating system unit 45 also stores and utilizes the mobile subscriber information and the authentication key. Also, depending on the user's setting, the mobile operating system unit 45 may have a terminated state, a suspended state, and a running state. The terminated state is the same as the state in which the cellular phone terminal is turned off. The suspended state is a state in which the virtual mobile operating system is mounted on the memory but the process is not activated. In the state of the mobile network 5, the mobile phone terminal enters the shadow area and no longer responds to the network signal . The running state refers to a state in which the mobile operating system is normally running and connected to the mobile network 5 to exchange signals with each other. Exceptionally, there may be a situation where the mobile network is connected but the valid subscriber authentication fails and registration to the network is not possible.

Further, the application executed by the mobile application unit 46 refers to various application programs installed and executed in the smartphone based on the mobile operating system. The user can download and install the application from the virtual mobile phone 400 in the same manner as downloading and installing the application through the market from the actual smartphone.

The gateway server 2 according to an embodiment of the present invention includes a hardware unit 21 for executing an operation of a physical device, an operating system (OS) 21 installed based on the hardware unit 21 and controlling the execution of hardware resources Unit 22 and a base station executing unit 23 in which a software-based BTS is installed and executed.

Here, the base station execution unit 23 serves as a mobile base station (BTS) for exchanging physical signals with the mobile operating system unit 45. The BTS is a device that transmits and receives radio signals to and from an actual physical mobile phone terminal on a GSM network over an IP-based mobile network. Similar to the BTS, the base station execution unit 23 serves as a gateway for connecting a signal from the virtual mobile phone 400 to the mobile network 5. The present invention is not limited to the case where the virtual mobile phone 400 is connected to the GSM mobile network, but in any case, a signal is transmitted between the virtual mobile phone 400 and the mobile network 5, Based gateway, and these functions are collectively referred to as a software-based BTS in the present invention for the sake of convenience. The software-based BTS is developed as a UNIX-based Open Source named Open BTS, and has a GSM, a SIP stack, and the like, and thus is suitable for use in the present invention.

Referring to FIG. 3, the mobile operating system unit 45 further includes a voice processing unit 451 and a subscriber information management unit 452. The mobile operating system unit 45 has a function to be added in addition to the functions of a general mobile operating system. For example, a voice processing function (speech processing function) for transmitting a voice signal to the base station executing unit 23 as digital data is a representative to be. In a practical physical phone terminal, the mobile base station codes radio frequency data into a digital voice signal. On the other hand, in the present invention, since all communication sections and data are generated by communication of digital data, the voice processing unit 451 of the mobile operating system unit 45 has a voice coding function for converting into digital data by the voice processing function, Transmission function. Therefore, a function of receiving and transmitting the voice of the digital data must be added to the base station executing section 23 connected to the virtual cellular phone 400. [

The mobile operating system unit 45 receives and stores the subscriber information of the mobile network 5 from the subscriber and when the virtual mobile phone 400 requests to be registered in the actual mobile network 5, The ability to include and transmit information should be added. In the case of a physical mobile phone terminal, the subscriber information is stored in the SIM card. In the virtual mobile phone 400, the subscriber information management unit 452 stores and manages the subscriber information and the authentication key received from the subscriber.

The base station executing section 23 directly connects to the mobile network 5 by a software-based BTS function. The base station execution unit 23 transfers data of the mobile network registration and data transmission of the virtual mobile phone 400 to the mobile network 5. [ The mobile network 5 can not distinguish between the virtual mobile phone and the actual mobile phone terminal. Only the mobile control station 510 or the mobile switching center 520 of the mobile network 5 connected to the base station executing unit 23 for managing the traffic or data transmitted to the virtual mobile phone Trigger and the like can be generated and managed. When the mobile network operator supports such a function, it is possible to set where the data signal of the mobile phone to be transmitted is transferred from the physical mobile phone to the virtual mobile phone.

As described above, the virtualization system 1 of the cellular phone includes the user terminal 3, the virtualization server 4, and the virtualization server 4 in order to implement data communication between the mobile phone terminal and the mobile base station connected by radio signals in an actual mobile communication service. And the base station executing section 23 of the gateway server 2, which are driven by the virtual mobile phone 400 and the gateway server 2, respectively.

4 is an exemplary view of icons 101 displayed on the screen 100 of the user terminal 3 according to an embodiment of the present invention. 5 is an example of a screen in which the icon 200 corresponding to the application of the virtual mobile phone is executed among the icons 101 shown in Fig.

Referring to FIG. 4, the user terminal 3 exemplifies a screen 100 of a smart phone, assuming that the user terminal 3 is a smart phone. A plurality of applications may be installed in the smart phone, and the smart phone displays icons 101 of the application installed on the screen. Among the icons 101 displayed on the screen 100, there is an icon 200 corresponding to the application 33 of the virtual mobile phone.

Referring to FIG. 5, there is shown a screen 201 in which the user has executed the icon 200 corresponding to the application 33 of the virtual mobile phone. Icons 202 of applications installed on the virtual mobile phone are displayed on the screen 201 of the virtual mobile phone. The phone button 203 on the screen 202 of the virtual mobile phone is a button for executing a call service of the virtual mobile phone. When the user presses the telephone button 203, the service screen of the call using the virtual mobile phone is displayed instead of the call of the actual smartphone.

Here, the actual phone of the smartphone and the virtual mobile phone may be the same or different from each other. For example, when the user joins the mobile communication service of the company A and the company B, the application 33 of the virtual mobile phone to which the telephone number subscribed to the company B is assigned to the actual smartphone to which the telephone number of the company A is assigned is installed It is possible to do.

As another example, when the user joins two lines of different telephone numbers from the company A, the application 33 to which the telephone number of the second line is assigned is installed in the actual smartphone to which the telephone number of the first line is assigned It is possible. In addition, the telephone number set in the actual smartphone may be the same as the telephone number set in the application 33 of the virtual mobile phone of the smartphone.

As another example, the mobile operating system installed in the actual smart phone and the virtual mobile operating system used by the application 33 of the virtual mobile phone of the smartphone may be the same or different. Accordingly, the user can set the actual mobile operating system and the virtual mobile operating system differently according to the needs, and install the applications for the respective mobile operating systems in the actual smart phone and the virtual mobile phone. Here, the virtualization server 4 executes a virtual mobile operating system, and the application 33 of the virtual mobile phone is executed based on the virtual mobile operating system. For example, A virtual telephone of the Android operating system can be used in the virtualization server 4 as a virtual telephone of the actual telephone while using the telephone. At this time, the user can download the iOS version A application 33 and install it on the actual smart phone, and download the Android version A application 33 and install it in the virtual phone of the virtualization server 4.

6 and 7 are schematic flowcharts of a method for virtualizing a mobile phone according to an embodiment of the present invention.

Referring to FIG. 6, the user terminal 3 executes the application 33 of the virtual mobile phone by setting the user's input or automatic execution (S101). The application 33 remotely accesses the virtualization server 4 by referring to the set address information (S102). If the daemon process unit 43 executed in the virtualization server 4 is running (S103), the daemon process unit 43 receives the connection request of the application and responds to the success message (S104). When the success message is answered, mutual messages and traffic exchange are made possible using the promised protocols. The virtualization server 4 must be prepared to execute a daemon process unit 43 to simultaneously receive a remote connection from a plurality of user terminals 3. [ If the virtualization server 4 is turned off or the daemon process unit 43 is not running, the application 33 can not accept the remote connection, and the application 33 outputs a failure message to the screen and the connection is terminated.

Upon receipt of the success message, the user account information set in the application 33 is input (S105), and the daemon process unit 43 receives the account information of the user from the application 33 and authenticates whether it is a valid account (S106).

Here, the account information is information on whether the number of the virtual mobile phone set in the application 33 is authenticated by the virtualization server 4 to have a proper right to receive the service of the virtual mobile phone. The account information should be obtained from the virtualization service provider of the mobile phone. Various authentication methods such as an ID password and a certificate may be used for authentication of account information, and the present invention is not limited to a specific authentication method. If the user is a normal user who has joined the mobile network, the authentication process is passed. If authentication fails, the application 33 that has received the authentication failure message from the virtualization server 4 terminates the connection.

If authentication of the account information is successful, the virtualization server 4 determines whether or not the mobile operating system corresponding to the virtual mobile phone of the account information is executed (S107). If not, the virtual operating server 4 executes the mobile operating system (S108) .

Here, if the virtualization server 4 determines that the mobile operating system unit 45 of the requested virtual mobile phone is running, then the user's input and output are processed in connection with the mobile operating system unit 45. If the mobile operating system unit 45 is not running, the virtual environment and the mobile operating system necessary for the drive must be newly activated. The user's connection may be paused until the mobile operating system is running and the user's input can be accepted. In addition, the virtualization server 4 must store the usage environment of the mobile operating system of the connected user account. Then, even when the connection of the user terminal 3 is interrupted or when the execution of the mobile operating system is stopped in the virtualization server 4 and then used again, the virtualization server 4 transmits the execution environment of the mobile operating system, (33).

If the mobile operating system unit 45 is running, the mobile operating system unit 45 determines whether the virtual mobile phone 400 is registered in the mobile network 5 (S109) The mobile network 5 of the virtual mobile phone 400 or the like (S110). The information of the registration request is signaled in accordance with the format of the mobile network 5 in the base station executing section 23 of the gateway 2 and then transmitted through the mobile control station 510 and the mobile switching center 520 in operation S111. Then, it is determined whether the subscriber is a valid subscriber by inquiring the user information in the SIM from the Visitor Location Register (VLR) and the Home Location Register (HLR) on the mobile network (S112). If the virtual cell phone 400 is an effective subscriber, (S113). When the virtual mobile phone 400 is registered in the mobile network 5, the application 33 waits for the generation of an event causing data reception or transmission (S114).

The process of registering the mobile network 5 in step S110 is similar to the process of registering in the mobile network 5 when the mobile phone terminal is turned on for the first time. Then, the registration process of the mobile network 5 is verified whether or not it is an effective subscriber registered in the mobile network 5, that is, the existing mobile network system can be used as a step of inquiring whether the mobile phone is a subscriber. If the verification is normally successful, the application 33 of the user terminal 3 indicates that the user's virtual mobile phone 400 is registered in the mobile network 5. [

In a state in which the application 33 waits for the occurrence of an event, a transmission or reception event of data using the virtual mobile phone 400 may be generated by a user's input. For example, the user can generate a call origination or wireless internet communication event and receive a call to the virtual mobile phone 400 by an event of call reception.

If the input event is generated by the user, the application 33 generates an input event of the user (S201). The daemon process unit 43 of the virtualization server 4 receives the input data of the user from the application 33 and the received data is transferred to the mobile operating system unit 45 through the emulator unit 44 of the virtual machine .

Referring to FIG. 7, when the mobile operating system unit 45 receives the user's input data, the mobile operating system 45 determines whether it can process itself or use the network (S202). For example, when the mobile operating system unit 45 processes the input of the user itself or when the mobile application unit 46 processes itself, the use of the network is not involved. The mobile operating system unit 45 processes the user's request using the mobile operating system or the mobile application, and then returns the processed result to the application 33 via the daemon process unit 43 (S204).

If it is determined that the use of the network is accompanied, the mobile operating system unit 45 in step S202 transmits a network dedicated packet generated from the user's input data to the base station executing unit 23 of the gateway server 2 . If it is determined that the virtual mobile phone 400 is registered in the mobile network 5 (S203), and if the virtual mobile phone 400 is not registered in the mobile network, the mobile operating system unit 45, in step S204, To the application (33).
