Definitions

• the invention relates to a method, a terminal and a server allowing the allocation of sub-addresses to fixed telephone terminals for the reception of short messages SMS (Short Message Service).
• SMS Short Message Service
• the SMS service for fixed telephony uses various protocols which, in Europe, are based on the intervention of a server and in-band communications, i.e. telephone calls requiring the establishment of '' a circuit, unlike the SMS service for mobile telephony which only uses signaling, without establishing a circuit.
• the protocol used is, for example, that of the ETSI standard ES201912.
• This service uses the Calling Line Identifier (CLI) line identification which is standardized under the reference ETS306659-1-2-3.
• CLI Calling Line Identifier
• the terminal calls the SMS server which stores the message and then sends it to the destination terminal.
• the server calls the destination terminal.
• the latter has the server call number in memory and therefore recognizes the latter by this number.
• the recipient terminal takes the line and then, after receiving the SMS message, hangs up automatically.
• the duration of the exchange is approximately 4 seconds. Since for the same telephone number, several terminals can be provided in parallel with separate users, the standard provides for the possibility of assigning to each of the terminals a sub-address allowing an SMS message intended for one of these terminals only arrive at this terminal.
• the maximum number of sub-addresses today is 10 (0 to 9). It is also possible to use the sub-addresses in the same multi-user terminal in order to identify the user receiving the message. In this case, access to the SMS service, in particular to messages received, may require the entry of a code specific to the user concerned. In the case where several terminals are in parallel, when the server sends an SMS message, only the destination terminal having the sub-address contained in the message takes the line. Similarly, when a terminal sends an SMS message, this terminal is identified by its sub-address, along with its call number. Thus, the called party can recognize the identity of the caller not only by the telephone number but also by the sub-address.
• the terminals compatible with the SMS service contain not only the server number but also a sub-address which, by construction, is generally sub-address 0.
• the introduction of other sub-addresses must be carried out manually by the user. This operation is often felt to be complex and therefore dissuades the use of the service in the case of use at several terminals or in the case where it may be desired that several distinct users can receive SMS messages on the same terminal.
• the invention makes it easier to introduce sub-addresses in an installation in which at least two terminals are in parallel with the same telephone number.
• the method according to the invention consists in automatically assigning at least one sub-address to a fixed telephone terminal connectable to an SMS server by the following steps: - a default sub-address is assigned by construction to the terminal, - the terminal sends a message to the SMS server in such a way that the latter responds with a message to the telephone number (or address) of the installation and to the sub-address sent by the terminal, - the terminal automatically detects if another terminal the installation takes the line or not, if after a determined time, no other terminal of the installation takes the line to receive the message from the server, the terminal automatically assigns the sub-address, and - if another terminal of the installation has taken the line, the terminal again sends a message to the server by assigning itself another sub-address and the terminal assigns this other sub-address if no other rminal of the installation does not take the line after a determined time following receipt of the message from the server, this step being repeated by further modifying the sub-address
• the server is such that when a terminal subscribes to the SMS service, this server returns an acknowledgment of receipt to the terminal, it suffices to provide an operation very simple which consists, for example, in pressing a single key which triggers the implementation of the method according to the invention. It is also possible not to use this acknowledgment service.
• the terminal is such that it sends a message which is intended for it, that is to say which is intended for its own telephone number and its sub-address.
• the constraint imposed on the user will simply be to ask him to enter his telephone number for sending an SMS message during the automatic allocation period described above.
• the modification of the sub-address automatically assigned to the terminal during the search for an available sub-address consists in increasing the previously selected sub-address by one.
• the terminal sends to the server, for example by a simple press of a key, a message requesting the allocation of one or more sub-address (s), and - upon receipt of this message from the terminal, the server responds by sending to the installation telephone number, a set of successive messages in number equal to the number of installation sub-addresses, namely 10 in general, and the terminal automatically assigns the sub-address or sub-addresses that have not been received by other terminals in the installation. In this case, the terminal only sends the server a single message, which is thus less costly for the subscriber.
• a terminal according to the invention comprises, whatever the method used: means for transmitting to a message server
• SMS a message triggering, in this server, the sending of an SMS message in return with a sub-address, and means for detecting if, to receive the return message from the server, another terminal of the installation takes the line, and means for assigning the sub-address of the message received if the latter has not been received by another terminal.
• a line voltage detector is provided, for example in this terminal.
• the terminal includes means for sending the SMS server a message with a default sub-address when registering for the SMS service.
• the terminal comprises the means for sending the server an SMS message which is intended for this terminal, this message comprising a default sub-address.
• the terminal in another embodiment for which the terminal is intended to be connected to an SMS server capable of sending to the address of the terminal a set of SMS messages the number of which is equal to the total number of sub-addresses, each message addressed to the installation having a sub-address distinct from that of another message in the set, the terminal includes means for transmitting, for example by simple pressing of a key, a request for allocation of sub-address (s) to the SMS server without it being necessary for this request to indicate a default sub-address for the terminal, the latter comprising means for assigning a sub-address or several available sub-addresses.
• s sub-address
• An SMS message server comprises means for recognizing a request for allocation of subaddress (s) originating from a fixed telephone installation terminal and means for sequentially addressing a number n of SMS messages to the installation, this number n being equal to the total number of sub-addresses for an installation, each of the n messages being intended for a determined sub-address, different from one message to another.
• the terminals if they are equipped with line occupation detection means can select the available sub-addresses.
• - Figure 1 shows a server and two terminals of a fixed telephone system for the transmission of SMS messages
• - Figures 2 and 3 are diagrams illustrating embodiments of methods according to the invention.
• a terminal 10 which wishes to send an SMS message to a terminal 12 addresses the message to an SMS server 14 by indicating its sub-address.
• the SMS message is sent with the recipient's number and its sub-address.
• the call number of the server 14 is by construction in memory in the terminal 10.
• the terminal automatically sends its telephone number and its sub-address.
• the message is stored in the server 14.
• the server 14 calls the terminal 12.
• the latter recognizes the SMS server by means of the CLI service, that is to say it compares the number received with the server number by memory.
• the terminal 12 therefore takes the line and automatically stores the message received from the server.
• the method according to the invention consists in automatically assigning a sub-address to a terminal 20 ⁇ (FIG. 2) of an installation comprising, for the same telephone number, a set of terminals, 2O2, 2O3, etc.
• the terminal 20 ⁇ addresses to the server 14 an SMS message 22 containing its sub-address so that the server 14 responds with an SMS message 24 with the same sub-address.
• the terminal detects whether, during a predetermined time delay, the other terminals 202 r 2O3, etc.
• the terminal 20 ⁇ assigns the sub-address determined by default such as sub-address 0. If this sub-address 0 is not available, it is ie if one of the other terminals 2O2, 2O3, ... replied to the SMS message during the timeout period, then the terminal sends another message 22 ⁇ to which the server responds with a message 24 ⁇ , the message 22 ⁇ containing a sub-address different from the sub-address of message 22, for example a sub-address increased by one. If the sub-address is available, the terminal 20 ⁇ assigns it. Otherwise, the process continues. The terminal 20 ⁇ can also allocate several sub-addresses with the same method.
• the terminal 20 ⁇ sends the server 26 a request 28 in the form of an SMS message and the SMS server responds with successive messages 30n, 301, ..., 309.
• These messages 30i are equal in number to the number of available sub-addresses, that is to say 10 in general (0 to 9) and each message has a different sub-address than that of the other messages.
• the message 30Q is intended for the sub-address 0
• the message 30 ⁇ is intended for the sub-address 1, etc.
• the terminal having issued the request comprises, in this embodiment (as in that described with FIG. 2), a line voltage detector.
• the terminal determines during a timeout period if each message has been received by another terminal and, if not, assigns the sub-address corresponding to the message from the server 26.
• the terminal determines during a timeout period if each message has been received by another terminal and, if not, assigns the sub-address corresponding to the message from the server 26.
• the procedure makes it possible to update the available sub-addresses.
