Description

System, Server, Terminal, and Method for Virtual Mobile Infrastructure

The present invention relates to a mobile virtualization service (Virtual Mobile Infrastructure), more specifically, a system, a server for providing a cloud-based next-generation mobile virtualization service that overcomes various disadvantages of mobile virtualization in the conventional terminal area , Terminal, and method.

Along with the spread of mobile devices, the high performance of terminals, the development of data communication technologies, and the development of various applications have emerged as an enterprise mobility environment. One of the sensitive factors in the enterprise mobility environment is the ownership problem of the terminal. To solve this problem, many companies have introduced a Bring Your Own Device (BYOD) policy that allows employees to use personally owned mobile terminal devices for their business. With the introduction of the BYOD policy, companies can expect to reduce IT costs, and individuals can expect the convenience of not having to manage a separate terminal for company work.

However, despite these advantages, there are inevitable risks associated with using personally-owned terminals for business. Security threat issues are inevitably raised because sensitive corporate information such as business emails, messenger conversations, file downloads, remote service access, and business application data are used and stored on personal devices. In other words, personal privacy and corporate security are always in conflict between one terminal.

To address these issues, companies are implementing policies to protect and manage the use of all mobile devices used in their work through Enterprise Mobility Management (EMM). The purpose of the EMM is to ensure that when a personally owned mobile device is used for work, it is appropriately controlled while at the same time allowing the user maximum flexibility in using the device. EMM has evolved into a variety of solutions. Among them, MDM (Mobile Device Management) method that utilizes device-level policies and MAM (Mobile Application Management) method that applies security policies to specific apps are the most representative.

However, the types and methods of security threats facing companies are diversifying and advanced. Therefore, a management policy in a more fundamental way than a method that can respond only to a specific threat is needed, and the technology introduced for this is the'mobile virtualization' technology.

Currently, the mobile virtualization technology introduced by companies mainly uses the virtualization method in the terminal area. That is, a separate area is encrypted in the mobile terminal and implemented in a virtualized form. Therefore, as shown in FIG. 1, as the personal area remains on the existing OS (Android, etc.) and a separate virtual area is newly created, an effect as if there is one more virtual terminal can be expected.

However, mobile virtualization in the terminal area has several important problems that are difficult to overcome despite many advantages.

First, even if a separate virtualization area is encrypted and completely separated and exists in the terminal, there is still anxiety about the security threat that the virtual area will invade the personal area of the terminal.

Second, as OS versions used in mobile terminals are diverse and new OSs continue to emerge in the future, it is difficult to predict all problems that the OS may have in the virtualization area.

Finally, since the virtualization area also exists in one terminal, the personal area and the virtualization area are forced to share and divide the resources of the terminal and face the phenomenon of performance degradation and terminal resource shortage.

Therefore, there is a need for a new next-generation mobile virtualization model that can overcome these shortcomings of conventional mobile virtualization in the terminal area.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In adding reference numerals to the components of each drawing, the same components have the same reference numerals as possible, even if they are displayed on different drawings. In addition, when it is determined that a detailed description of a known configuration or function related to the embodiments of the present invention may obscure the subject matter of the present invention, the detailed description will be omitted.

Figure 2 is a block diagram of a system for a mobile virtualization service according to an exemplary embodiment of the present invention, as shown in the figure, including a communication network (1), the user mobile terminal (3), and the server (4) Can.

The communication network 1 may be any network, either alone or in combination, that allows the user's mobile terminal 3 and the server 4 to connect and communicate by wire, wireless, and/or the Internet.

The user mobile terminal 3 has a dedicated launcher or app for a mobile virtualization service, and runs the launcher or app to access the server 4 through the communication network 1, and the server 4 ) To display the screen of the mobile operating system transmitted and received, and to enable the user to use the mobile operating system booted from the server 4 in real time through the displayed screen, for example, voice communication, video communication, data It may include a smart phone, a tablet, a laptop, a general PC, and the like capable of communication and Internet communication.

Since the mobile virtualization service according to the exemplary embodiment of the present invention uses the resources of the server 4, it is not affected by the specifications of the user terminal (Client) 3.

Therefore, even if a specific application of the enterprise requires a high-performance terminal environment, the same effect can be expected even with a low-end terminal through the mobile virtualization service of the present invention.

This has the advantage of significantly lowering the cost of terminal deployment in the case of a company that has a business model for distributing dedicated terminals for specific apps. That is, the terminal can be used only in the form of a dummy terminal in which a wireless Internet based mobile operating system (for example, Android or IOS) is operated. Therefore, the mobile virtualization service of the present invention can provide an optimal service to a company that wants a thin client model.

Another advantage of these clients is that enterprises can reduce the cost of launcher that they develop and operate in order to control the resource access of the terminal to a desired level for security purposes. In addition to the high development cost, the launcher needs to be verified for each terminal, operating system, and version, and requires continuous support for security defects. In the mobile virtualization service of the present invention, the client may provide an advantage that such launcher development is unnecessary or minimized.

Even in a thin client environment, the terminal must receive and play compressed audio/video (AV) through wireless Internet communication with the server, which affects communication speed. Therefore, a communication environment with a constant speed (eg, 4G) or higher is recommended.

In the mobile virtualization service environment of the present invention, the user mobile terminal (Client) 3 can receive services in the following two types.

1) Dedicated terminal: Service is available in the form of a dedicated terminal when it is for educational purposes, closed group users, or to perform specific functions. The dedicated terminal is a method in which a dedicated launcher is put at the firmware level and when the terminal is booted, the dedicated launcher is executed directly on the mobile OS layer. The launcher has control over all the resources of the terminal to prevent the mobile terminal 3 from being used for other than the designated purpose. Depending on the purpose of the dedicated terminal, you can restrict the rights of using the USB port, using the Internet, using the browser, using the App Store, using the camera, and using the microphone.

The default screen of the launcher is fixed at all to the connection screen of the mobile virtualization server 4 so that the user can use the mobile terminal 3 only for the purpose of the mobile virtualization service.

In addition, if a specific group wants to censor the voice communication, text transmission, and messenger for a user group, or to allow only a specific time zone, link the launcher and the gateway of the communication network 1 to turn on specific functions and virtualize the log. Server 4 can be recorded.

2) Access through a dedicated app for mobile virtualization: General users can download and install a dedicated app from the Play Store or App Store using their mobile terminal 3, and this app is a mobile virtualization service of the present invention. In order to use, membership registration, payment, and server access are provided. If the app is installed and verified as an authenticated user, anyone can conveniently use the mobile virtualization service of the present invention with their mobile terminal (3). The app does not pose any security threat to the user's mobile terminal 3 and can be deleted at any time.

The mobile virtualization server 4 is provided with at least one mobile operating system (OS) corresponding to the user mobile terminal 3 (in the form of an image), and when the user mobile terminal 3 is connected, the corresponding mobile operating system is booted and booted. The screen of the mobile operating system may be transmitted in real time to the connected user mobile terminal 3.

Since the mobile virtualization service of the present invention is a mobile environment operating on the server 4, a mobile operating system also exists on the server 4. For example, any version of the mobile operating system provided as open source can be used. It is also possible to use a customized operating system customized through operating system modifications. Therefore, it is possible to design the initial screen and configuration of the operating system as desired by the company, and it is possible to use several versions of the design in one server 4.

The designed operating system is mounted on the server 4 in the form of an image. Now, when a request is received from the user's mobile terminal (Client) 3 to the server 4 through the communication network 1, the server 4 can boot the operating system image through the virtual machine. The screen of the operating system booted on the virtual machine of the server 4 is transmitted to the user mobile terminal (Client) 3 through the communication network 1 and finally displayed on the user mobile terminal 3.

When multiple versions of the operating system are installed and operated on one server 4, requests received from the user terminal 3 can be identified and separated, for example, and requested to the virtual machine. You can use a mobile environment.

One of the key elements of the mobile virtualization service according to an exemplary embodiment of the present invention is a technique of transmitting audio/video of a virtual machine operating on the server 4 to the user terminal 3. First, in a general VMI concept, when the video transmission process is divided into steps, the server screen image -> Compression -> Gateway -> Relay server -> Communication network -> User terminal as shown in FIG. -> Decompression -> Regeneration.

The process of FIG. 6 inevitably causes the server 4 and the terminal 3 not to be synchronized in real time, that is, latency. Slight latency does not significantly affect interactive tasks, but it can be a problem for games and educational apps.

The mobile virtualization service according to an exemplary embodiment of the present invention can minimize latency of screen and sound with the following technology.

The mobile virtualization service according to an exemplary embodiment of the present invention can minimize latency by improving compression performance performed at the server 4 side and improving the transmission protocol performed at the communication network 1 in the step of FIG. 6.

1) Compression: When the emulator process of the mobile operating system (e.g. Android) is running, NVFBC can be activated to capture the GPU buffer. This method captures the frame buffer without the intervention of OpenGL or Direct3D, and is suitable for high-speed encoding by minimizing the amount of data copied between the GPU and CPU. GPU information captured by NvFBC is transmitted to NVENC and encoded. In other words, NVENC is an ideal GPU-side encoding and carries H.264 type.

2) TCP/UDP Socket communication: When passing through the relay server layer (RTMP/RTSP) used for general streaming transmission, the transmission speed is affected. Therefore, the mobile virtualization service of the present invention can be designed to improve the transmission speed by removing this and adopting a method of directly transmitting audio and video to the terminal through TCP/UDP socket communication. Also, during the decompression process, it is possible to find a codec supported by the GPU of the terminal and apply an API that increases the decoding speed.

In addition, the mobile virtualization service of the present invention can be implemented by combining Qemu emulator with Kernel-based Virtual Machine (KVM) virtualization technology. 7 shows the operational layers of Qemu Emulator and KVM virtualization technology in server 4.

KVM is a solution that enables virtualization through CPU acceleration. Virtualization technology through this CPU acceleration has a very stable and superior performance compared to a virtualization solution that is not. KVM has superior virtualization performance than Intel's HAMX technology, which is considered a competitive technology.

A mobile environment operating in the cloud is basically a volatile environment. That is, when the user terminates the connection, the VM environment operating on the server 4 is terminated, and the mobile screen transmission of the server 4 is stopped. When the user reconnects, the Gateway boots the initialized mobile operating system mounted on the server (4). Therefore, the data that the user worked online can be stored and reused in the company's database and storage, but the final operating environment of the mobile operating system configured by the user is initialized and the desired configuration must be reset each time.

In addition, if a connection is interrupted due to a communication failure or the like while executing a specific task in the cloud mobile environment, all incomplete (unsaved) tasks disappear.

In addition, keeping the cloud mobile environment open online to wait for long-running work results may increase the cost of using the communication network 1 and the user terminal 3.

In order to solve this problem, the mobile virtualization service of the present invention enables the mobile virtualization environment to provide a service to selectively use a persistent mode and a non-persistent mode.

In the mobile virtualization service according to an exemplary embodiment of the present invention, the server 4 may enable resources to be terminated (Terminated mode), stop mode (Stop-Run mode), and persistent mode (Persistent mode).

In the terminated mode, when the user 3 terminates the connection, all resources used by the server 4 are cleared and returned to the server 4. This is a one-time mode, which is the simplest and most affordable model to use mobile virtualization.

In the Stop-Run mode, when the user (3) terminates the connection, the operating system environment used and configured so far is stored in the server (4) as a snapshot, and all the used server (4) resources are cleared and the server (4 ). When the user 3 re-connects (Run), the operating system environment saved as a snapshot is rebooted so that the user can connect and use the last working environment. This mode is a model that can use the mobile virtualization service at a much lower cost than continuously using other resources of the server, although additional storage charges for storing the snapshot are charged.

Persistent mode is a mode in which only the screen transmission from the server 4 to the user terminal 3 is stopped when the user 3 terminates the connection, and the mobile environment and work of the server 4 are maintained. Therefore, the user terminal 3 may be used for other purposes until the user reconnects, and even in this case, all resources of the server 4 are continuously used, so a higher usage fee may be charged than in the stop-run mode. When the user reconnects, the mobile screen of the server 4 that was working independently is transmitted back to the user.

The gateway (not shown) is an app (APP) that enables users to access and control the mobile virtualization technology of the server 4, even if the functionality and performance of the gateway is poor, no matter how excellent mobile virtualization technology is. Will not be able to provide the optimal service. Therefore, the gateway of the mobile virtualization service of the present invention can provide the following services to users.

① Authentication service through user login and security protocol

② Intelligent server branch service according to server usage

③ Auto scaling service according to server use port

④ Multiple access service that allows a single user to use multiple VMs

⑤ Log storage and call service for persistent mode

⑥ Snapshot creation, storage and storage access service for Stop-Run mode

⑦ Auto-Manual Shutdown Service

Referring to FIG. 4, a device 40 for a mobile virtualization service according to an exemplary embodiment of the present invention includes a database 41, a booting part 43, a transmitting part 45, and a control part 47 Can.

The database 41 is for providing one or more mobile operating systems corresponding to the user mobile terminal 3 in an image form, for example, one or more mobile operating systems and/or desired ones among all versions of the mobile operating systems provided as open source By modifying the operating system, multiple versions of the mobile operating system, such as a customized customized operating system, can be mounted in the form of images to be used on a single server.

When the user mobile terminal 3 is connected to the server 4, the booting unit 43 boots and executes the corresponding mobile operating system corresponding to the connected user mobile terminal 3 among the one or more mobile operating systems provided in the database 41. It is to do.

The transmitting unit 45 is for real-time transmission of the screen of the mobile operating system booted/executed through the booting unit 43 to the connected user mobile terminal 3 for display.

The control unit 47 is for controlling the user to use the mobile operating system booted/executed from the server 4 through the screen of the mobile operating system displayed on the screen of the mobile terminal 3, for example, at the time of termination of the user's connection. The server 4 is controlled to operate in a terminated mode for clearing and returning all resources used in the server 4, or as another example, when the user terminates the connection, the mobile operating system environment that has been used and configured so far as a snapshot server 4 ), all resources that were stored and used are cleared and returned. When the user reconnects, control to operate in the stop-run mode to reboot the stored mobile operating system environment, or as another example, when the user terminates the connection It can be controlled to stop in the screen transfer and operate in a persistent mode to maintain the environment and work of the mobile operating system.

5 is a flowchart of a method for a mobile virtualization service according to an exemplary embodiment of the present invention, which is applied to the apparatus of FIGS. 2-4 and is described in parallel with the operation of the corresponding politics.

The mobile virtualization server 4 has a plurality of different versions of the mobile operating system (OS) (S501), and the user mobile terminal 3 is equipped with a dedicated launcher or app (S503).

Subsequently, the user mobile terminal 3 accesses the mobile virtualization server 40 by executing the loaded dedicated launcher or app (S505) (S507), and the mobile virtualization server 4 performs the user mobile terminal 3 through step S507. Is connected (S509), the mobile operating system corresponding to the connected user mobile terminal 3 is booted (S511).

The transmitted screen is displayed in real time and the mobile operating system booted/executed on the server 4 can be used through the displayed screen (S515), and at the same time, the mobile virtualization server 4 is in a terminated mode or a stop mode ( Stop-Run mode), in step S515 according to the selected mode of the persistent mode (Persistent mode) is driven so that the user can use the mobile operating system through the screen (S517).

As described above, the management function is essential for the mobile virtualization service of the present invention to operate properly. Who will you allow access to? Which version of the operating system will each user use? Who needs to stay connected? What is the life cycle of the user's snapshot? How do you grant permissions for multiple apps in your enterprise? And so on, the CS-VMI infrastructure itself faces numerous challenges that cannot be solved.

The mobile virtualization service of the present invention is provided with a management tool capable of managing these points and an app for Client, through which the manager and user of the enterprise can register and manage the points as shown in FIG. 8.

Next, applications in various fields of the mobile virtualization service of the present invention will be described.

Education

Many educational companies supply members (students) with dedicated terminals equipped with educational apps. Most of them supply low-priced pads that meet the minimum hardware requirements required for their apps to operate, but face difficulties in continually upgrading their devices due to customer needs and advancement of apps.

In addition, separate software must be developed to block the use (access) of terminal functions (resources) that interfere with learning (possibly interfere), and these software are managed separately for each terminal and each terminal operating system. It is difficult to respond to security issues.

In addition, there is a case where the learning app does not guarantee the same operation and performance in various versions of terminals, and additionally, technical C/S work has increased.

As a result, many companies spend a lot of money on supplying learning-only terminals, but they realize that it takes more money and resources for post-maintenance and management, so they give up the business.

In order to solve the problems of the education companies, the next feature of the mobile virtualization service of the present invention may be an optimal solution.

First, the user terminal 3 does not need to meet the minimum hardware specification for the app because the educational app operates on the operating system of the server 4. Also, even if the app is advanced, there is no need to upgrade the user terminal 3.

Second, the educational app is imaged with the tested mobile operating system and mounted on the server 4, so the same operation and performance can be expected in various versions of terminals.

Third, at the time of selecting the terminal 3, unnecessary functions and resources of the terminal 3 may be removed (blocked), or a dummy terminal 3 may be designated and used.

Finally, personalized app services (professor programs, LMS, additional services, etc.) for each member level can be continuously provided to the terminal 3 without additional environment setting or app installation, so that a long-term business plan can be established.

Lab field

Terminals used by users in security-sensitive organizations such as research institutes, enterprises, and businesses are important management points for security threats. Users must perform activities necessary for work such as telephone, messenger, message, e-mail, access to the internal network through the terminal.

However, through such daily business activities, there is a risk that security information is leaked to the outside or confidential information and data of the company are not deleted after being used in the terminal.

Because of these security threats, introducing a policy to control various terminals of all users faces another difficulty described above.

In this business environment, the next feature of the mobile virtualization service and the launcher-equipped service of the present invention can provide an optimal solution.

First, the administrator can control the use of telephones, texts, etc. for each user and for each time zone, so that communication with an individual or time zone for a specific activity can be blocked.

Second, individual usage can be controlled for individual apps such as emails and messengers.

Third, it is possible to keep track of all incoming and outgoing voice communication and text communication logs. Such log tracing can be done quickly with specific string tracing by applying additional solutions.

Fourth, since all of the company data used is stored in the server 4, no confidential information or garbage data of the company remains in the user terminal 3. Due to this, it is possible to prevent data leakage due to user negligence. In particular, when the user uses the camera of the terminal 3, since the captured image or image is stored in the user terminal 3 and not directly transmitted to the server 4, information leakage through the camera can also be blocked.

Business field

In today's business environment where mobility and speed must be guaranteed, companies are distributing dedicated terminals to employees who work outside and move for specific tasks. These industries continue to expand, including construction, logistics, courier, finance, and insurance.

Companies should continue to bear the burden of replacement costs due to deterioration of terminals as well as the cost burden of paying for high-end dedicated terminals.

It also faces the challenge of immediately applying the business logic changes of applications running on dedicated terminals. If the application's business logic is not updated at the same time by region or terminal, this can lead to huge customer claims as well as financial losses to the company.

Another risk faced by companies is a security threat that may cause sensitive information, such as customer personal information, to remain on the terminal and leak.

The burden of the enterprise can be solved through the following features of the mobile virtualization service of the present invention.
