System for providing cloud-based user interfaces and method thereof

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.

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.
