ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a terminal for use in a communication network and comprising a plurality of terminal capability functions to realize a plurality of terminal capability features and coupled thereto a terminal application execution apparatus to interact with one or more of the plurality of terminal capability functions and to execute thereby a terminal application, the terminal application to be executed by such a terminal, a carrier of such a terminal application, a method realized by such a terminal, and a communication network comprising such a terminal.
Such a terminal with terminal capabilities and terminal applications means coupled thereto to interact with the terminal capabilities and to execute thereby a terminal application is especially known in communication networks referred as a Universal Mobile Telecommunication Systems UMTS. For such an UMTS network the concept of Virtual Home environment is defined. A Virtual home environment is defined as a concept for personal service environment portability across network boundaries and between terminals. The concept of the Virtual Home environment is such that users are consistently presented with the same personalized features, User Interface customization and services in whatever network and whatever kind of terminal, wherever the user may be located. The Virtual Home Environment is seen as a key mechanism for convergence of fixed and mobile terminals, for public and private networks and operators and for telecommunication and data communication systems.
A terminal, either fixed terminal or mobile terminal, for use in such a virtual home environment comprises terminal capability means where for here below a non-exhaustive list of examples is provided:
a Wireless Application Protocol WAP client that communicates via a WAP gateway with a WEB server in the Internet or other terminals. WAP specifies an application framework and network protocols for wireless devices such as mobile phones, pagers and personal digital assistants. The network protocols specify a way of transporting data between an Internet Protocol IP network and mobile terminals. The application framework enables the creation of Internet like services; and
a Wireless Telephone Application WTA client that communicates with a WTA server in the network. WTA specifies an application framework that extends the WAP architecture with telephony services. It is a collection of telephony specific extension for call and feature control mechanisms that make advanced Mobile Network Services available to users. In contrast with classical client-server architecture e.g. WAP where the client continuously communicates with the server for the execution of the services actually running on the server, WTA adopts a terminal centric approach. WTA services run in the WTA client on the mobile terminal, which only communicates with the WTA server for maintenance and reconfiguration reasons; and
a Java execution environment such as e.g. a Java card. A JavaCard is a recent evolution in the area of smart-cards with an enhanced architecture that has a Java Card Virtual Machine JCVM on top of its native Operating System OS and allows to develop applications written in Java programming language; and
a User Service Identity Module USIM module that comprises e.g. an authentication algorithm and a ciphering key, a card identification, a user identification, network and service related data and UMTS SIM applications i.e. USIM applications; and
a SIM Application Tool-kit provides mechanisms which allow applications that exist on the USIM to interact and to operate with any part of the mobile equipment of a mobile terminal.
It has to be remarked that according to the virtual home environment definitions a User Service Identity Module that identifies a user can be comprised in as well a fixed terminal as a mobile terminal. Such a USIM card comprises terminal capability means but might as well comprise terminal applications means with a terminal application.
The above mentioned terminal capabilities are realizing terminal capability features whilst being supported by terminal bearers such as e.g. short message service SMS, circuit switched data and Generic Packet Radio Service. It has to be mentioned that a particular manufacturer develops these terminal capability features and terminal bearers. In this way the terminal capability features and terminal bearers are technology dependent according to the choices of a manufacturer.
The known kind of terminals further comprises a terminal application means to interact with one or more of the terminal capabilities in order to execute a terminal application.
A terminal application provides to a user of a terminal a particular service such as e.g. ‘a call forwarding application according to the user's preferences’ or ‘a voice message application’ or ‘personal banking applications’, etc. It has to be remarked that such a terminal application is a hardware module or, more commons, a software module. Such a software module terminal application is information e.g. logic and data that can be stored at production time on e.g. a read only memory of the terminal, but on the other hand, it might as well be downloaded from a service provider in the telecommunication network on e.g. an accessible memory of the terminal during operational use of the terminal. It has to be remarked that such a terminal application is usual designed according to a higher programming language level.
A terminal application means comprises at least part of the data concerning the present application and an application execution environment. In this way the execution environment, under the support of the associated terminal capability means, executes the data of the application e.g. a WAP application means executes a particular WAP application by interacting with the associated WAP client.
It has to be remarked here that since the terminal capability means is technology dependent according to a certain manufacturer, that also the related application is developed towards this technology of this manufacturer. Indeed, in order to be executed by the terminal application means that interacts with the terminal capability means the terminal application must be designed according to the same interfaces. This means that an application signal that is transmitted by the terminal capability means is received and understood by the terminal application means that executes an application being developed according to the same manufacturer preferences as the one used for the terminal capability means, and vice versa.
A problem outstanding with such kind of terminals is that in the event when a third party service provider develops a terminal application for use on a terminal, that the application must be written for different underlying technologies preferred and used by different manufacturers of terminals. Indeed, a terminal application developed according to preferences of a first manufacturer is not able to cooperate via the terminal application means with a terminal capability means being developed according to preferences of a second manufacturer.
Furthermore, two different terminal applications applied on a same terminal are not able to interact with each other when being designed for different kind of terminal capability means.
SUMMARY OF THE INVENTION
An object of the invention is to provide a terminal for use in a communication network that executes a terminal application such as the above known terminal but which has not the above mentioned drawback of the requirement of development of different terminal application designs for execution of a this terminal application by interacting with different terminal capability means of possible different manufacturer's underlying technology.
This is realized by a terminal (T) for use in a communication network, said terminal (T) comprising a plurality of terminal capability means (CAP
