Mobile cloud system and operating method of the same

1. A mobile cloud system, comprising:

a plurality of mobile terminals, each of the plurality of mobile terminals having at least one functional module and a mobile cloud platform;

a cloud server to receive and process information acquired from the at least one functional module, the cloud server including:

a read-only file system to provide common services commonly applied to all the mobile terminals configured to be connected to the cloud server, the read-only file system including a shared database, a shared memory, firmware, an operating system, and first applications commonly used by the plurality of mobile terminals,

a read/write file system to provide user-specific services individually applied to each of the mobile terminals configured to be connected to the cloud server, the read/write file system including a user-specific database, a user-specific memory, and applications containing information specific to individual ones of the plurality of mobile terminals, the applications being encrypted and backed up in the user-specific memory, and

a controller configured to determine whether a request from the mobile terminal is to be processed in the read only file system or in the read/write file system, and to control operations of the read-only and read-write file systems by communicating the request to the corresponding file system; and

a wireless communication network to provide one or more communication channels between the plurality of mobile terminals and the cloud server;

wherein the mobile cloud platform is configured to manage authentication information of the mobile terminal.

2. The mobile cloud system of claim 1 , wherein the at least one functional module comprises one or more of a display module, an audio module, an input module, a camera module, and a GPS module.

3. The mobile cloud system of claim 1 , wherein the mobile cloud platform is further configured to: communicate with the wireless communication network and the cloud server, and maintain and manage a channel formed between the mobile terminal and the cloud server for providing a cloud service; and provide the cloud service to the mobile terminal.

4. The mobile cloud system of claim 3 , wherein the authentication information includes at least one of hardware information such as a MAC address, a CPU ID, and an IMEI allocated to each mobile terminal.

5. The mobile cloud system of claim 3 , wherein the cloud service comprises a cloud computing service.

6. The mobile cloud system of claim 1 , wherein the read-only file system comprises a shared database, a shared memory, firmware, an operating system, and applications commonly used by the plurality of mobile terminals.

7. The mobile cloud system of claim 1 , wherein the controller comprises a processor capable of processing signals of the at least one functional module transmitted from the plurality of mobile terminals.

8. A method of operating a mobile cloud system, the method comprising the steps of:

booting a mobile terminal having at least one functional module and a mobile cloud platform;

authenticating whether the mobile terminal can receive a cloud service;

operating the mobile cloud platform installed in the mobile terminal and activating the cloud service;

transmitting signals acquired from the at least one function module in the mobile terminal to a cloud server through the mobile cloud platform;

processing the signals from the at least one function module in the cloud server, and managing authentication information of the mobile terminal in the mobile cloud platform, wherein the step of processing the signals further comprises the steps of:

determining whether the signals from the at least one functional module are to be processed in a read only file system including a shared database, a shared memory, firmware, an operating system, and first applications commonly used by the plurality of mobile terminals, or in a read/write file system including a user-specific database, a user-specific memory, and second applications containing information specific to individual ones of the plurality of mobile terminals, the second applications being encrypted and backed up in the user-specific memory, in the cloud server;

storing information in the shared memory of the read only file system in the cloud server if the signals from the at least one functional module comprising information corresponding to a common service area, and providing services commonly applied to all the mobile terminals connected to the cloud server; and

storing information in the specific-user memory of the read/write file system in the cloud server if the signals from the at least one functional module comprising information corresponding to a user-specific service area, and providing user-specific services individually applied to each of the mobile terminals connected to the cloud server.

9. The operating method of claim 8 , wherein the step of authentication comprises allocating hardware by using information from at least one of a MAC address, a CPU ID, and an IMEI allocated to each user who uses the mobile terminal whenever the cloud service is requested.

10. The operating method of claim 8 , wherein the step of operating the mobile cloud platform installed in the mobile terminal and activating the cloud service comprises activating a cloud computing service.

11. The operating method of claim 8 , further comprising the step of: communicating with a wireless communication network and the cloud server, and maintaining and managing a channel formed between the mobile terminal and the cloud server for providing a cloud service; and providing the cloud service to the mobile terminal.
