ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to a method of setting and performing freely programmable functions of a telecommunications terminal, and to a telecommunications terminal with function control keys and a control unit for initiating freely programmable functions.
2. Discussion of Related Art
Since the invention of the telephone, telecommunications terminals have undergone an astonishing development. From simple telephones with the functions “lifting the handset—talking and listening—hanging up”, through direct dialing, first only with a rotary dial using dial pulse signaling and later with keys using multifrequency signaling and, based thereon, abbreviated dialing with function keys, to PCs, which also serve as telecommunications terminals and also provide communications capabilities other than only voice communication, the applications of telecommunications terminals have multiplied. As a result, however, both the possibilities of and the requirements for control actions, such as the programming of short codes, have greatly increased. Operating aids are manifold, too. For example, by actuating a single function key, a whole process can be initiated, or displays are used which serve to detect input errors. It is also known, for example, to assign a particular function to a function key in a menu mode with the aid of a display. Such a menu mode may also be voice-controlled.
SUMMARY OF INVENTION
For both older people and, for example, people with impaired vision, the individualization of function keys is frequently still too troublesome. To this must be added that, as a rule, only those functions can be specified, such as wake-up call at predetermined times, call forwarding or abbreviated dialing to predeterminable destinations, which were intended for the respective set from the beginning.
According to a first aspect of the invention, a method of setting and performing freely programmable functions of a telecommunications terminal with function control keys and a control unit for initiating functions which were selected by actuating predetermined function control keys initiating the respective functions, and with an access unit providing access to a telecommunications network is characterized in that for the purpose of setting or performing a function, a connection is established between the control unit and a service unit in the telecommunications network via the access unit, and that the setting or performance of the function takes place from said service unit.
According to a second aspect of the invention, a telecommunications terminal with function control keys and a control unit for initiating freely programmable functions which were selected by actuating predetermined function control keys initiating the respective functions, and with an access unit providing access to a telecommunications network is characterized in that the control unit and the access unit are interconnected in such a way that a data exchange is possible between the control unit and the telecommunications network.
The invention is based on the idea to permit intervention in the control unit associated with the function keys from the telecommunications network. This makes it possible to either influence the programming of the functions keys from the network or control a service unit in the network directly from a function key, which service unit then performs the desired function. The individual programming of this service unit need not be carried out by the user, either.
Further advantageous features of the invention are defined in the subclaims and will become apparent from the following description.
