- FIG. 1 presents a block diagram of a telecommunications assembly in which various subscriber telephone terminal units are represented, the connection of which to a central office of a telephone network is carried out by means of analog telephone lines. These units and the exchanges to which they are attached are assumed to be provided one and the other to allow the implementation of the method according to the invention.
- the method of transmitting information according to the invention is intended to be implemented within the framework of a telecommunications system allowing the establishment of communications by telephone and / or radiotelephone; a nonlimiting example of such a system is shown diagrammatically in the single figure.
- a system of this kind comprises at least one telephone network 1 intended to allow the connection of various subscriber telephone terminal units which are here supposed to be connected for this purpose to telephone exchanges 2, 2 ′ of network 1 via analog telephone lines L, the exchanges being themselves assumed to be interconnected.
- Telephone terminal units are materials made available to users, they are likely to be very diverse, as schematically illustrated in the single figure.
- terminal units consisting of telephone sets 3 which are individually connected to a connecting telephone exchange 2 'each by an analog telephone line L.
- a terminal unit of a shared telephone installation 4 which constitutes a main telephone unit 5 of this unit and which is connected to a home telephone exchange 2 by a telephone line L, or possibly a small number of such lines.
- the terminal unit which constitutes the main unit 5 of the shared telephone installation is supposed to make it possible to serve a plurality of subscriber telephone terminals 3 ', compatible with each other and here symbolized by telephone sets.
- Such a unit is provided to allow users of the terminals, who share it, to enter into communication with other telephone or possibly radiotelephone terminals via the telephone network 1, via the analog telephone line or lines L serving installation.
- the main unit 5 comprises in particular information processing means, here symbolized by a management logic 5D associated with switching means 5C.
- switching means make it possible to connect, in a manner known per se, the telephone terminals 3 ', which the unit serves, to the home exchange 2 on which it depends, and this by means of the analog telephone line or lines L which connect it to this central.
- the switching means 5C can be particularly reduced if the terminals 3 ′ are mounted in parallel on a line, they are more generally of the type with "n" terminal ports and "m" line ports, n and m being positive integers.
- the main telephone unit 5 can possibly serve cordless telephones, if it is provided with radio transceiver means enabling it to communicate selectively with, for example, the handset of a terminal cordless, this handset is most often fitted with a built-in dial pad.
- a terminal unit is shown, it is assumed to be constituted by a main radiotelephone unit 7, of a shared installation intended to allow the service of accredited users having radiotelephone terminals 8, such as for example cordless telephones, such as DECT, CTO, CT1 type models, or even laptops, such as GSM or other models.
- radiotelephone terminals 8 such as for example cordless telephones, such as DECT, CTO, CT1 type models, or even laptops, such as GSM or other models.
- the main unit 7 is supposed to include switching means 7C making it possible to selectively connect one of the accredited radiotelephone terminals 8, which are connected to it, with the or one of the telephone line (s) L to which it is connected. It also includes a 7D management logic allowing it to act, in particular on the switching means 7C according to the needs of the users and the availability.
- the main unit 7 further comprises transmission-reception means by radiotelephone channel 7A and interface means 7B to enable the operation of these transmission-reception means in connection with the switching means 7C under the control of 7D management logic. Operation is more particularly dependent on requests arriving by radio from accredited radiotelephone terminals or from the home telephone exchange 5 by analog telephone line L.
- Access to the telephone network by radio telephony terminals through a main home connection unit 7 is made possible for accredited terminals 8 which are in the radiotelephone coverage area of this main unit 7 and which are validly located near it, for example as some do, under other conditions, with a radio station radiotelephone network base 6.
- the accredited radiotelephone terminals are in the radiotelephone coverage area of this main unit 7 and which are validly located near it, for example as some do, under other conditions, with a radio station radiotelephone network base 6.
- the accredited radiotelephone terminals are in the radiotelephone coverage area of this main unit 7 and which are validly located near it, for example as some do, under other conditions, with a radio station radiotelephone network base 6.
- radiotelephone terminals 8 are for example subscriber terminals of the same organization, such as a small business, which has a main unit 7 for its needs.
- the accredited terminals are then likely to be conventional mobile radiotelephone terminals of a radiotelephone network offering these services to the public. They are located near the main unit 7, when they are in its coverage area, to communicate by telephone with all the users to whom the telephone network 1 gives access. Outside this zone, these radiotelephone terminals 8 operate in a conventional manner after having been individually located, each with one of the base stations of the public radiotelephone network, at radiotelephone range from which it is then located.
- the messages are put in a form allowing them to be directly exploitable by the information processing means which receive them. They are coded in a way that allows an analog telephone line to transmit and to the receiving telephone terminal unit to receive them for interpretation.
- a terminal unit is therefore necessarily equipped with suitable decoding means, these means possibly being already provided in the unit for other purposes.
- decoding means which are not shown here, are housed at a line interface level and connected to information processing means, for example a processor, in the terminal unit which includes that it is a simple terminal, such as a telephone set or complex equipment such as a main shared installation unit or a telephone exchange.
- the messages are for example transmitted in V23 or DTMF code, the receiving terminal unit being equipped with transcoding means, known in themselves, allowing their translation into a classically binary code usable by the processing means of the unit, such than the 5D and 7D management logic.
- Such directly exploitable messages are in particular provided to allow the home exchange of a subscriber telephone terminal unit to respond with an action command message to a service request, such as a call numbering of a correspondent or activation of an additional service. This operation is then carried out by or through the terminal unit, at the instigation of a user served by this unit.
- action command messages can in particular be used after processing in the unit which receives them, for example by the 5D or 7D management logic of this unit, to trigger immediate or delayed actions at the level of the unit or in the case of one or more of the terminals which it makes it possible to connect to the telephone network.
- the display on screen is a particular mode and it is also possible to use means for transforming the signals to be displayed, for example in the form of acoustic signals produced by synthesizers or stored as recorded messages, especially for users with blindness. It is also planned to associate the transmission of information via such a message, via a telephone line, with a specific tone or voice message sent via the same line either before or possibly after.
