Abstract

Disclosed are a system for providing cloud-based user interfaces and a method thereof. More particularly, a subscriber terminal device according to the present disclosure may include a control command receiver configured to receive a first control command including description information on a template repeated on a UI (User Interface) screen and a second control command including a replication command for the template from a remote application server; a template generator configured to generate a template the based on the description information on the template; a UI resource acquirer configured to acquire a UI resource based on the second control command; and a UI element generator configured to generate UI elements based on replication of the template and apply the UI resource to the UI element.

Claims

1. A subscriber terminal device, comprising:

a control command receiver configured to receive a first control command including description information on a template repeated on a UI (User Interface) screen and a second control command including a replication command for the template from a remote application server;

a template generator configured to generate a template based on the description information on the template repeated on the UI screen;

a UI resource acquirer configured to acquire a UI resource based on the second control command;

a UI element generator configured to generate UI elements based on replication of the template and apply the UI resource to the UI elements,

wherein the second control command includes information on a number of the generated template when the template is repeated in the UI screen; and

a controller that comprises at least one processor, wherein, when the control command receiver receives a third control command designating the template as a local UI, the control command receiver transfers the third control command to the controller, wherein the controller checks a memory allocated to the local UI and stores description information of the template in the memory when a memory capacity allocated to the local UI is equal to or larger than a predetermined value, wherein the controller transmits a return message to the remote application server when the memory capacity allocated to the local UI is smaller than the predetermined value.

2. The subscriber terminal device according to claim 1, wherein the second control command further comprises information on the number of the generated UI elements based on the replication of the template, a UI resource information applied to each of the UI elements when the number of the generated UI elements is plural, and screen coordinate information on each of the UI elements.

3. The subscriber terminal device according to claim 2, further comprising renderer configured to render the UI elements based on the screen coordinate information on each of the UI elements and provide a UI screen to a display device.

8. The subscriber terminal device according to claim 2, wherein the control command receiver receives a control command to configure UIs including description information of a UI element and configures UIs using the description information on the UI element and the UI resource information.

9. The subscriber terminal device according to claim 1, wherein the description information on the template comprises size of the template, position of the template, and attributes of the UI resource.

4. A remote application server, comprising:

a control command generator configured to generate a control command for configuring a UI (User Interface) screen displayed on a subscriber terminal device;

a controller configured to control generation of the control command; and

a communicator configured to transmit the control command to the subscriber terminal device,

wherein the control command generator, when a template of a UI element is repeatedly used in the UI screen, generates description information on the template,

the control command generator generates a first control command comprising the description information on the template,

the controller controls the control command generator to generate a second control command comprising a replication command for the template and information on a UI resource to be applied to the UI element,

wherein the second control command includes information on a number of generated template when the template is repeated in the UI screen, and

the controller further comprises at least one processor, wherein, when the control command generator generates a third control command designating the template as a local UI, the third control command is transferred to the controller, wherein the controller checks a memory allocated to the local UI and stores description information of the template in the memory when a memory capacity allocated to the local UI is equal to or larger than a predetermined value, wherein the controller transmits a return message to the remote application server when the memory capacity allocated to the local UI is smaller than the predetermined value.

5. The remote application server according to claim 4, wherein the second control command further comprises replication command for the template, information on a number of UI elements generated by the replication command of the template, a UI resource information applied to each of the UI elements when the number of the generated UI elements is plural, and screen coordinate information on each of the UI elements.

10. The remote application server according to claim 4, wherein the description information on the template comprises size of the template, position of the template, and attributes of the UI resource.

11. The remote application server according to claim 4, wherein the control command generator generates a first control command excluding description information on a template of a UI element when the template is not repeatedly used in the subscriber terminal device.

6. A method of providing UIs of a remote application server in a cloud-based UI provision system, the method comprising:

determining whether a template of a UI element comprised in a UI screen is repeatedly used in a subscriber terminal device;

generating description information on the template when the template is repeatedly used;

generating a first control command comprising the description information on the template;

generating a second control command comprising a replication command for the template and information on a UI resource to be applied to the UI element;

transmitting the at least one of the first control command and the second control command to the subscriber terminal device,

wherein the second control command includes information on a number of the generated template when the template of the UI element is repeatedly used in the UI screen;

generating a control command excluding the description information on a template of a UI element when the template is not repeatedly used in the subscriber terminal device; and

transmitting the control command to the subscriber terminal device.

7. A computer program stored in a non-transitory computer readable recording medium to perform the method according to claim 6.

12. A method of claim 6, wherein the second control command further comprises information on the number of the generated UI elements based on the replication command, the UI resource information applied to each of the UI elements when the number of the generated UI elements is plural, and screen coordinate information on each of the UI elements.

13. A method of claim 6, wherein the description information on the template comprises size of the template, position of the template, and attributes of the UI resource.
