A client-side application and a corresponding remote application are installed on the terminal device and on a server connected to the terminal device. The remote application dynamically splits the tasks to be performed by the content delivery application between the client-side application and remote application, according to its computational resources and processes, in real-time, the content and its associated logic and input data to be delivered to the terminal device. The processed content is then transmitted to the terminal device over the data network and the content is rendered by the client-side application. The client-side application responds to inputs from the user and/or to messages from the server or further connected devices.

METHOD AND SYSTEM FOR OPERATING APPLICATIONS FOR

REMOTE TERMINAL DEVICES

Field of the Invention

The present invention relates to the field of mobile communication

Applications. More particularly, the invention relates to a method and system for allowing a user of a terminal device to remotely operate

upgraded and/or advanced applications without the need for upgrading the

client side application or computational resources.

Background of the Invention

Many modern mobile applications involve content provisioning, such as

browsing, gaming, financial applications, music, ring tones and other multi media applications. On-Line applications such as browsing and Wireless Application Protocol (WAP) based applications that require data exchange

with a data network allow the mobile devices to access the data required

for further processing by the device. Mobile applications are normally

developed with adaptation to the properties of a specific terminal device of a group of devices with similar computational capabilities, such as

memory, processors, operating system, display size and graphical

resolution, as well as the base set of application programming interfaces

for resource-constrained terminal devices, such as Connected Limited Device Configuration (CLDC) that when coupled with a profile such as the - Z -

Mobile Information Device Profile (MIDP), provide a Java platform for

developing applications to run on devices with limited memory, processing

power, and graphical capabilities. Current solutions for developers of such applications focus mainly in upgrading the developing tools for each

terminal device.

The differences between the properties of different terminal devices entail design problems, since any attempt to make adaptations of an application to be compatible with several types of terminal devices restricts the

capabilities of that application to comply with the terminal device which is the most resource-constrained. On the other hand, individual adaptation

(also known as "porting", which is the process of adapting software to make it usable in a different environment) is costly and cumbersome, particularly when many new models are frequently added to the market.

In addition, the development of applications for mobile terminal devices

requires specific knowledge of the design tools, the limitations of each

device and expensive testing verification processes, which are carried out on each device.

Another problem is related to the process required to add new applications

and to upgrade or fix bugs in existing applications, which includes

downloading the new applications or upgrading files into the device. - J -

U.S. 2006/235925 (Rossotto et al.) discloses a multimedia service content provision method that uses wireless communication network, and involves

interpreting received packets at client terminal, so as to obtain interactive presentation of multimedia service content, based on the service logic.

According to this method, delivery packets that convey both the

multimedia service contents and corresponding service logic are generated.

The multimedia contents can thus be presented interactively at the terminal while new services can be designed on the server side and made

available to the user terminals without modifications being required on the terminal side. However, this method uses a predetermined logic, which

doesn't react in real-time to the state of the application and to the

capabilities of the terminal device. More over, the proposed method still

requires adaptation of the client-side application to each terminal device. In addition, Rossotto does not allow several users to interact with each

another and influence, in real-time, the executed application at the

terminal device of each other, as well as the content displayed to each one

of them (e.g., interactions between employees of the same organization or users that participate in a common game).

Other existing platforms allow a user of a mobile device to develop mobile software over another platform (over .NET, for example) and then to adapt

the client-side software to be able to be executed on that mobile device. However, this adaptation is done offline, thus still requiring the development, dispatch and installation of new client-side software for each

update, fix operation or whenever a new application is added. In addition, developers who provide development tools that are added to the client-side

application code generally increase the resources required from the

terminal device, and are even sometimes useless for several models of

devices with lower capabilities.

AU the methods described above have not yet provided satisfactory solutions to the problem of providing design tools of mobile applications

that do not require adaptation of the client-side application to each

terminal device, and that react in real-time to the state of the application

and to the capabilities of the terminal device.

It is an object of the present invention to provide a method and system for

providing design tools of mobile applications that do not require

adaptation of the client-side application to each terminal device.

It is another object of the present invention to provide a method and

system for providing tools for execution, dispatch and platform installation

of mobile applications that do not require adaptation of the client-side

application to each terminal device. It is another object of the present invention to provide design tools of

mobile applications that react in real-time to the state of the application and to the capabilities of the terminal device.

It is a further object of the present invention to provide design tools of

mobile applications that effectively exploits the capabilities of the terminal device.

It is yet another object of the present invention to provide design tools that allow maximization of the device capabilities, and developing and

executing applications that are beyond the inherent device capabilities.

It is still another object of the present invention to provide design tools of

mobile applications that can be easily implemented and simplify their verification process.

It is still another object of the present invention to provide design tools of

applications that can be easily developed and implemented across platforms such as mobile devices and TV's.

Other objects and advantages of the invention will become apparent as the description proceeds. - b -

Summary of the Invention

The present invention is directed to a method for allowing a user of a mobile terminal device having predetermined computational resources to

remotely develop and operate upgraded content delivery application(s). A client-side application and a corresponding remote application are

installed on the terminal device and on a server being in data

communication with the terminal device, respectively. The server exchange data with the terminal device and the remote application

dynamically splits the tasks to be performed by the content delivery application between the client-side application and remote application,

according to its resources. The remote application adaptively processes,

preferably in real-time, the content (multimedia, graphics etc.) and its associated logic and input data to be delivered to the terminal device. The processed content is then transmitted to the terminal device over the

data network and the content is further rendered by the client-side

application. The client-side application responds to inputs from the user

and/or to messages from the server or further connected devices.

The resources are the memory capacity, processing capacity, multimedia

capabilities, graphical capabilities (display size, resolution, colors, 3d,

processing power etc.), wireless features, such as BlueTooth (BT), GPS,

J2ME capabilities (Java 2 Platform, Micro Edition) is a technology that

allows programmers to use the Java programming language and related tools to develop programs for mobile wireless information devices such as cellular phones), add-on devices and add-on software, operating system

capabilities, profile representing the specification of the terminal device,

or any combination thereof.

Whenever a change in the logic of the application and/or in the content

delivery application is required, only the remote application is updated on the server. Whenever required, the content may obtained by the server

from external sources over the data network.

The data network may be the Internet; a cellular data network; a satellite

data network; a wireless data network, a computer network, a digital data

transfer network, a cable TV. The terminal device may be a cellular telephone, a PDA, a satellite phone, any electronic unit capable of

executing software, a computing device capable of executing software or a TV or TV Set-top box.

Whenever a new content delivery application, a change in logic, update, or

fix operation are required, a new remote application is installed on the

server only, while allowing the client-side application to interact with the new content delivery application. The content delivery applications may be electronic games, enterprise

applications, multi-users applications, information rendering, 3-D graphical presentation, multimedia, voice, location based application,

digital content, music or video/TV presentation.

Brief Description of the Drawings

The above and other characteristics and advantages of the invention will be better understood through the following illustrative and non-limitative

detailed description of preferred embodiments thereof, with reference to

the appended drawings, wherein:

Fig. 1 schematically illustrates the architecture of a system for allowing a user of a terminal device to remotely operate upgraded and/or

advanced application, according to the present invention.

Detailed Description of Preferred Embodiments

According to the method proposed by the present invention, each content

providing application is executed by a combination of a remote (server)

application that runs on a server that is connected to a data network and a

client-side component, which is generic and installed on each terminal

device. The client-side component is designed to be compatible with many

different terminal devices with different capabilities and will serve all types of applications that should be operated. Any required change, upgrade or adaptation of an application will not entail any change in the client-side component, but will be made in the remote application on the

server. This way, the client-side component will be in data communication

with the server, for exchanging data and instructions/requests and for

transferring more heavy tasks to be executed by the server. The proposed

solution reduces the time to market required for adaptation of the remote

application to new devices, updating services, logic and content in the

remote application, rather than in the device. This also allows

development of new applications using programmatic environments that

are more familiar to developers. More over, this allows maximization of

the device inherent capabilities or capabilities that are provided by its

accessories (e.g., add-on devices), and developing and executing

applications that are beyond the device (limited) capabilities, such as CPU

power and memory.

The capabilities of the remote server will be used for implementing the

application logic for each operated application, execute portions of the

required tasks and as a gateway to be in data communication with other

information sources that are also connected to the data network. In

addition, the server will perform most of the graphical processing

according to the known capabilities of the terminal device and deliver, in

real-time, the processed image or graphical data in a format that is

optimized to the capabilities of the specific device, such as the display size, resolution, colors, intensity, etc. (and hence, no porting process is

required).

Fig. 1 schematically illustrates the architecture of the system proposed by

the present invention. The system 10 comprises several layers, such that

each layer performs a required task. The security layer supports all other

layers. These layers are the client layer 101, the distribution layer 102, the

communication layer 103a, the Client Adaptation layer 103b, the (remote)

application layer 103c, the database management layer 104 and the

security layer 105.

The remote server 106 implements 3 layers:

- The Communication Layer 103a; this layer includes an interface to the

mobile terminal devices, using the services provided by the cellular

providers. This layer also performs data communication with the client

communication layer 101, so as to allow the remaining higher level layers

to perform the application and the graphical and multimedia tasks, as well

as other tasks (e.g., determining screen size, resolution, 3-D effects, colors

etc.).

- The Client Adaptation Layer (CAL) 103b: this layer is used to generate

real-time, high resolution, multidimensional and multimedia

presentations of complex data at high speeds) and performs real-time processing of graphical tasks and adaptation of the content to be delivered

to a terminal device , according to its capabilities regarding voice, video,

3-D visualization and computer generated graphics. Content attributes

adaptation to the capabilities of each terminal device maximally exploits

them to enhance the presentation effects to the user.

- The Application Layer 103c: this layer supports connectivity with client-

side applications of different terminal devices, such as cellular devices,

TV-s or devices that are connected via the Internet or other data network.

In addition, this layer provides connectivity to external gaming servers, for

incorporating gaming engines into the applications and to extend existing

games into the mobile market, for implementing a desired application

logic, for promoting product or services by pushed advertising content, for

implementing disconnection logic, for connecting to the BackOffice Server

(a dedicated family of bundled servers and operating system) of an

enterprise for which an application is developed or of the cellular provider.

The disconnection logic handles disconnection events, as may happen in

cellular infrastructure. In such events, this logic uses the information

regarding the stage of the application at the moment when disconnection

occurs, and if the memory of the terminal device contains sufficient data

and processed content (such as save files and graphical setup), this logic

allows the user to continue interacting with the application locally, until

interaction with the server is required. The client layer 101 is designed to comply with a family of terminal

devices with similar capabilities, such that it can easily run on each device of a corresponding family. The Client may be of a simple type that corresponds to more restricted-resource devices or of a more advanced type that corresponds to less restricted-resource devices, such as 3-G devices.

The client layer 101 implements two layers:

- The Client Communication Layer 101a: this layer includes the unique

interface between the mobile terminal device and the remote server 106.

The Client Application Layer 101b: this layer includes the computational

capabilities required to properly execute the client-side application on the mobile terminal device, which includes logical rules, voice, video, 3-D visualization and computer generated graphics. This layer is designed to

be effective and flexible, so as to provide the required functionality without

overloading the terminal device's resources. This layer also handles the

interface, to data from the server, as well as inputs from the user. In addition, this layer optimizes performance by locally storing data files received from the server, so as to reuse it whenever possible and to locally

execute operations, according to instructions from the remote server (such

operations may include, for example, arithmetic operations, selection of objects, moving cursors etc.). As a default, rendering operations are performed by the remote server, unless a specific device provides

indication to the remote server about its capabilities to perform them

efficiently.

This distributed architecture descried above also allows providing the user advanced user interface and results that are much higher than the

inherent capabilities of the terminal device itself. In addition, the proposed solution also allows multi-user client-side applications to interact

with the remote server, so as to participate an interactive session, such as

games etc.

Even tough the description above is related to a mobile terminal device, the method proposed by the present invention can be implemented to other remote devices which are not mobile or portable, but in order to provide a

desired content, are connected to a remote server over a data network and

that are considered to be resource-constrained (comparing to a desktop

computer).

Therefore, the above examples and description have of course been provided only for the purpose of illustration, and are not intended to limit

the invention in any way. As will be appreciated by the skilled person, the invention can be carried out in a great variety of ways, employing more than one technique from those described above, all without exceeding the

scope of the invention.
