ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a telephony device comprising a set of elements formed by:
a base station having, inter alia:
* a processor assembly,
* a memory containing an execution program, and
* a random access memory,
at least one handset having, inter alia:
* a display,
* a processor assembly,
* control means for modifying at least one service inside one of said elements,
transmission means for transmitting messages between the base station and the handsets.
The invention relates to a handset and a base station suitable for such a telephony device.
The invention also relates to a method implemented in such a telephony device and also relates to a handset and a base station suitable for such a telephony device.
The invention finds interesting applications in telecommunication systems implying protocols, which is notably the case with telephony devices satisfying the DECT standard, for example.
BACKGROUND OF THE INVENTION
According to this standard, it is possible by means of a handset to have the base station carry out orders. According to known techniques, this is called the transparent mode for programming various services to be carried out by the base station.
Because of the fact that one works by means of controls which are keyed in on the keyboard of handsets and which are then transmitted by radio channels which are likely to fade, one is not certain that the requested operation is suitably executed.
SUMMARY OF THE INVENTION
The present invention proposes a device as defined in the opening paragraph which ensures a better control of the base station from handsets.
Therefore, such a device is characterized in that it further comprises:
transmission means for transmitting to at least one of said elements an order to carry out a service.
The idea of the invention consists of pre-establishing the tasks to be carried out at the level of the base station so that, in response to a single information signal of executing an order, the base station executes this order.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
