Description

SYSTEME ET PROCEDE DE COOPERATION D ' UNE PLATEFORME DE SERVICE TELEPHONIQUE AVEC UNE PLATEFORME DE SERVICE DE TYPE INTERNET SYSTEM AND METHOD FOR COOPERATING A TELEPHONE SERVICE PLATFORM WITH AN INTERNET-TYPE SERVICE PLATFORM
La présente invention concerne un système et un procédé de coopération d'au moins une plate-forme de service téléphonique avec au moins une plate-forme de service d'un réseau à commutation de paquets. Elle se situe dans le domaine des plate-formes de service réseaux et permet notamment d'offrir une grande synergie entre les différents types de réseaux existants . Elle trouve typiquement son application dans l'offre, aux usagers de ces réseaux, de services à valeur ajoutée tels que par exemple la signalisation d'un appel téléphonique sur le terminal d'un usager connecté à Internet, etc..The present invention relates to a system and method for cooperating at least one telephone service platform with at least one service platform of a packet switched network. It is located in the area of network service platforms and in particular offers great synergy between the different types of existing networks. It typically finds its application in the offer to users of these networks of value-added services such as for example the signaling of a telephone call on the terminal of a user connected to the Internet, etc.
Récupérer des informations sur un usager connecté à une plate-forme de service orientée données de type Internet, telle qu'une plate-forme de messagerie instantanée par exemple, pour les utiliser sur une plateforme de service du monde de la téléphonie, fixe ou mobile, est actuellement complexe à mettre en œuvre et nécessite une intégration forte entre la plate-forme téléphonique et la plate-forme du réseau de type Internet. L'invention va maintenant être présentée en regard d'une réalisation de l'art antérieur : la figure 1 schématise un système connu permettant de signaler un appel téléphonique sur un terminal d'un usager connecté à Internet. II existe aujourd'hui des systèmes qui permettent de gérer une information de présence d'un usager connecté sur le réseau Internet et de l'utiliser pour le réseau téléphonique commuté RTC. Ces systèmes correspondent à celui représenté sur la figure 1, et comprennent un réseau téléphonique commuté RTC et un réseau intelligent. Le réseau intelligent comporte une plate-forme de service de type Internet et une plate-forme 30, formant un point de commande de service dans le réseau intelligent, qui héberge dans cet exemple le service de signal d'appel sur Internet. Cette plate-forme 30 est destinée à communiquer avec d'une part la plate-forme de service de type Internet et d'autre part une plate-forme 10 du réseau téléphonique RTC.Retrieve information about a user connected to an Internet-type data-oriented service platform, such as an instant messaging platform for example, for use on a service platform from the world of telephony, fixed or mobile , is currently complex to implement and requires strong integration between the telephone platform and the Internet-type network platform. The invention will now be presented with reference to an embodiment of the prior art: FIG. 1 diagrammatically shows a known system for signaling a telephone call on a terminal of a user connected to the Internet. Systems exist today which make it possible to manage the presence information of a user connected to the Internet network and to use it for the PSTN switched telephone network. These systems correspond to that shown in FIG. 1, and include a PSTN switched telephone network and an intelligent network. The smart grid includes a service platform Internet type and a platform 30, forming a service control point in the intelligent network, which in this example hosts the call waiting service on the Internet. This platform 30 is intended to communicate on the one hand with the Internet-type service platform and on the other hand with a platform 10 of the PSTN telephone network.
Une application spécifique doit également être implantée dans le terminal 25 Internet, tel qu'un ordinateur par exemple, de chaque usager désirant bénéficier de ce service de signal d'appel sur Internet. Cette application permet de dialoguer avec la plate-forme 30 et permet notamment de lui transmettre une information sur l'état de la connexion entre le terminal 25 de l'utilisateur et la plate-forme de service de type Internet. Cette information garantie la présence de l'utilisateur sur son terminal 25 connecté et donc fourni la raison de l'occupation de la ligne téléphonique. Dans la suite de la description, on emploiera les termes "présence" lorsque le terminal d'un utilisateur est connecté au réseau de type Internet et "absence" lorsqu'il ne l'est pas. La plate-forme 30 communique par ailleurs avec le commutateur C de la plate-forme 10 téléphonique. Ainsi, lorsqu'un appel téléphonique à destination d'un abonné x téléphonique, connecté au réseau de type Internet par 1 ' intermédiaire de son terminal 25x arrive sur le commutateur C, il déclenche un appel au service de signal d'appel sur Internet hébergé par la plate-forme 30. Pour cela, un déclenchement de service sur occupation de la ligne de l'abonné x a été préalablement configuré sur le commutateur C. La plate-forme 30 peut alors envoyer un message sur le terminal 25x Internet de l'usager x destinataire pour l'avertir que quelqu'un cherche à le joindre sur son poste Tx téléphonique. Si l'usager x destinataire n'a pas connecté son terminal 25x à Internet, mais est en cours de communication téléphonique, sa ligne téléphonique est occupée. Dans ce cas, la plate-forme 30 sait que cet abonné n'est pas connecté à Internet, elle avertit donc le commutateur C qu'il peut alors router l'appel de manière classique vers le commutateur de la plate-forme téléphonique à laquelle est affecté le poste Tx téléphonique du destinataire x.A specific application must also be installed in the Internet terminal, such as a computer for example, for each user wishing to benefit from this call signaling service on the Internet. This application makes it possible to dialogue with the platform 30 and in particular makes it possible to transmit to it information on the state of the connection between the user's terminal 25 and the service platform of the Internet type. This information guarantees the presence of the user on his connected terminal 25 and therefore provides the reason for the occupation of the telephone line. In the following description, the terms "presence" will be used when a user's terminal is connected to the Internet type network and "absence" when it is not. The platform 30 also communicates with the switch C of the telephone platform 10. Thus, when a telephone call to a telephone subscriber x, connected to the Internet type network by means of its terminal 25 x arrives on switch C, it triggers a call to the call signal service on the Internet hosted by the platform 30. For this, a service trigger on busy line of subscriber x has been previously configured on switch C. The platform 30 can then send a message to the 25 x Internet terminal of the user x recipient to warn him that someone is trying to reach him on his telephone T x extension. If the user x recipient has not connected his 25 x terminal to the Internet, but is in the middle of a phone call, his phone line is busy. In this case, the platform 30 knows that this subscriber is not connected to the Internet, it therefore warns the switch C that it can then route the call in a conventional manner to the switch of the telephone platform to which is assigned the telephone extension T x of recipient x.
Ce type de système permet d'adapter l'infrastructure existante du réseau de communication pour prendre en charge les fonctionnalités d'un nouveau service de signal d'appel sur Internet par exemple. Cependant, ce système est lourd, complexe et coûteux à mettre en œuvre. En effet, il nécessite l'implantation d'un service spécifique sur la plate-forme 30. De ce fait, l'architecture de ce système ne peut pas évoluer facilement et être adaptée à d'autres types de services imbriqués des mondes de la téléphonie et de l' Internet . Cette architecture ne peut donc pas être introduite à grande échelle dans les réseaux de communication. Par ailleurs, du fait de l'importance grandissante accordée aux services de type "Chat" sur Internet, c'est à dire aux services de discussion écrite en temps réel entre plusieurs personnes définissant un groupe ou forum de discussion, les plate-formes de service du monde de l'Internet doivent sans cesse évoluer et s'adapter. Ainsi, dans le cas du "Chat", les plate-formes de service ont été modifiées pour pouvoir gérer 1 ' information de présence des usagers lorsqu'ils sont connectés à Internet. Les usagers désirant accéder à ce type de service doivent implanter une application dans leur terminal dédié à Internet. Cette application leur permet de s'authentifier auprès de la plate-forme de service du réseau Internet à laquelle ils sont reliés et de transmettre une information de présence dès qu'ils se connectent à Internet. Ainsi, lorsqu'une personne d'un groupe de discussion veut discuter avec une ou plusieurs personnes de son groupe, il transmet une information de présence et reçoit également de la plateforme une information sur la présence des personnes du groupe qui sont connectées à Internet. Grâce à cette information de présence échangée entre les usagers et la plate-forme, une discussion peut s'établir entre les personnes du groupe qui sont connectées .This type of system makes it possible to adapt the existing infrastructure of the communication network to support the functionalities of a new call signal service on the Internet for example. However, this system is cumbersome, complex and costly to implement. Indeed, it requires the establishment of a specific service on the platform 30. As a result, the architecture of this system cannot easily evolve and be adapted to other types of nested services from the worlds of telephony and the Internet. This architecture cannot therefore be introduced on a large scale in communication networks. In addition, due to the growing importance given to "Chat" type services on the Internet, that is to say, real-time written discussion services between several people defining a discussion group or forum, service to the internet world must constantly evolve and adapt. Thus, in the case of "Chat", the service platforms have been modified to be able to manage the presence information of the users when they are connected to the Internet. Users wishing to access this type of service must install an application in their dedicated Internet terminal. This application allows them to authenticate themselves to the service platform of the Internet network to which they are connected and to transmit presence information as soon as they connect to the Internet. So when someone in a focus group wants to chat with a or several people from his group, he transmits presence information and also receives information from the platform about the presence of people in the group who are connected to the Internet. Thanks to this presence information exchanged between users and the platform, a discussion can be established between the people in the group who are connected.
Aussi, le problème technique à résoudre par l'objet de la présente invention est de proposer un système de coopération d'au moins une première plate-forme d'un réseau téléphonique avec au moins une deuxième plate-forme d'un réseau à commutation de paquets, ladite deuxième plate-forme étant apte à gérer une information de présence d'au moins un usager commun à la première plate-forme lorsque celui-ci est connecté audit réseau à commutation de paquets, qui permettrait aux différents types de plateforme d'échanger des informations relatives aux usagers afin de leur offrir des services de type téléphonie et Internet très imbriqués, tout en gardant une architecture de réseau adaptable et simple à mettre en œuvre.Also, the technical problem to be solved by the object of the present invention is to propose a system of cooperation of at least a first platform of a telephone network with at least a second platform of a switched network. of packets, said second platform being able to manage the presence information of at least one user common to the first platform when the latter is connected to said packet-switched network, which would allow different types of platform to '' exchange information relating to users in order to offer them very nested telephony and Internet type services, while maintaining an adaptable network architecture that is simple to implement.
La solution au problème technique posé est obtenue, selon la présente invention, du fait que ladite première plate-forme dudit système comprend :The solution to the technical problem posed is obtained, according to the present invention, from the fact that said first platform of said system comprises:
- des moyens d'accès à ladite deuxième plate-forme, comprenant un module adaptateur apte à adapter un flux de commande dudit réseau téléphonique à un protocole de transmission dudit réseau à commutation de paquets,means of access to said second platform, comprising an adapter module capable of adapting a control flow of said telephone network to a transmission protocol of said packet switched network,
- un module de référencement destiné à associer un premier profil téléphonique dudit usager à un deuxième profil Internet, transmis par ladite deuxième plate-forme et correspondant audit usager, - une mémoire tampon destinée à stocker ladite information de présence qui est transmise par ladite deuxième plate-forme, des moyens de filtrage aptes à commander 1 ' envoi d'un message vers ladite deuxième plate-forme en fonction des profils et de 1 ' information de présence associée audit usager.a referencing module intended to associate a first telephone profile of said user with a second Internet profile, transmitted by said second platform and corresponding to said user, a buffer memory intended to store said presence information which is transmitted by said second platform, filtering means able to control the sending of a message to said second platform according to the profiles and the information presence associated with said user.
Ainsi, le système selon l'invention permet aux différents types de plate-forme de service réseaux de communiquer entre-elles en vue de partager une même information de présence des usagers lorsqu'ils sont connectés au réseau de paquets. Ce partage de l'information de présence entre une plate-forme du monde de la téléphonie et une plate-forme du monde de l'Internet permet d'offrir aux usagers de ces deux mondes des services de type téléphoniques et Internet très imbriqués, tels que par exemple la notification d'appel sur un terminal Internet ou bien l'établissement d'appel téléphonique à partir d'un terminal Internet. Cette coopération des deux types de plate-formes permet d'utiliser des informations croisées en provenance des deux plate-formes pour enrichir les services de chacune d'elles.Thus, the system according to the invention allows the different types of network service platform to communicate with one another in order to share the same user presence information when they are connected to the packet network. This sharing of presence information between a platform in the world of telephony and a platform in the world of the Internet makes it possible to offer users of these two worlds very similar telephone and Internet type services, such as as for example the call notification on an Internet terminal or the establishment of a telephone call from an Internet terminal. This cooperation of the two types of platforms makes it possible to use cross-information coming from the two platforms to enrich the services of each of them.
De plus, grâce au système selon l'invention, l'architecture de réseau reste simple et ouverte. Elle est adaptable à différentes fonctionnalités.In addition, thanks to the system according to the invention, the network architecture remains simple and open.

- à la figure 2 annexée qui représente un schéma bloc d'une architecture d'un système selon l'invention.- Figure 2 attached which shows a block diagram of an architecture of a system according to the invention.
Le système représenté comporte une première plate- forme 100 téléphonique reliée à des terminaux 150 téléphoniques d'usagers par l'intermédiaire d'un réseau 160 téléphonique. Le réseau 160 téléphonique est par exemple constitué par un réseau fixe tel que le RTC ou le RNIS, ou bien par un réseau mobile de type GSM ou GPRS par exemple. Selon le type de réseau 160 les terminaux 150 téléphoniques des usagers sont reliés au réseau par une liaison filaire ou par une liaison radio.The system shown comprises a first telephone platform 100 connected to user telephone terminals 150 via a telephone network 160. The telephone network 160 is for example constituted by a fixed network such as the PSTN or the ISDN, or else by a mobile network of GSM or GPRS type for example. Depending on the type of network 160, the telephone terminals 150 of the users are connected to the network by a wired link or by a radio link.
Une deuxième plate-forme 200 est reliée à des terminaux 250 d'usagers par l'intermédiaire d'un réseau 260 à commutation de paquets, de type réseau Internet par exemple. Les terminaux 250, ci-après dénommées terminaux Internet, sont par exemple des ordinateurs reliés au réseau à commutation de paquets par une ligne de communication filaire, ou bien des terminaux mobiles de type PDA par exemple ("personal digital assistant" en terminologie anglo-saxonne) ou téléphones mobiles aptes à être connectés sur des pages d' informations de type ap du réseau à commutation de paquets par l'intermédiaire d'une liaison radio. Les terminaux 250 Internet comportent une application logicielle permettant de transmettre une information de présence à la deuxième plate-forme 200, à laquelle ils sont reliés, lorsqu'ils se connectent au réseau de type Internet .A second platform 200 is connected to user terminals 250 by means of a packet switching network 260, of the Internet network type for example. The terminals 250, hereinafter referred to as Internet terminals, are for example computers connected to the packet switched network by a wired communication line, or else PDA type mobile terminals for example ("personal digital assistant" in English terminology). Saxon) or mobile phones capable of being connected to information pages of the ap type of the packet switched network via a radio link. The Internet terminals 250 comprise a software application making it possible to transmit presence information to the second platform 200, to which they are connected, when they connect to the Internet type network.
Les usagers sont définis pour toute la suite de la description comme étant des usagers communs au monde de la téléphonie et au monde de l'Internet.The users are defined for the rest of the description as users common to the world of telephony and the world of the Internet.
La première plate-forme 100 téléphonique comporte des moyens 110 d'accès à la deuxième plate-forme afin de pouvoir échanger des informations. Ces moyens 110 d'accès comprennent de préférence un module adaptateur apte à adapter le flux de commande du réseau téléphonique au protocole de transmission du réseau à commutation de paquets . Grâce à la présence du module adaptateur dans les moyens 110 d'accès, quel que soit le protocole de communication des différents réseaux, les plate-formes peuvent communiquer et se comprendre. Le protocole utilisé pour le transport de flux de données dans le réseau à commutation de paquets est par exemple basé sur le langage XML.The first telephone platform 100 includes means 110 for accessing the second platform in order to be able to exchange information. These access means 110 preferably comprise an adapter module able to adapt the control flow of the telephone network to the transmission protocol of the packet switched network. Thanks to the presence of the adapter module in the access means 110, whatever the communication protocol of the different networks, the platforms can communicate and understand each other. The protocol used for transporting data flows in the packet-switched network is for example based on the XML language.
Pour simplifier la figure 2, une seule plate-forme 100 téléphonique et une seule plate-forme 200 Internet sont représentées mais l'invention ne se limite pas à ce schéma et plusieurs plate-formes téléphoniques peuvent être connectées à une plate-forme Internet et réciproquement. Tous les usagers de la première plateforme 100 téléphonique ne sont pas forcément tous reliés à une seule et même plate-forme 200 Internet, si bien que, pour recevoir des informations relatives à tous les usagers qui lui sont affectés, il est important que la première plate-forme 100 téléphonique puisse se connecter à plusieurs plate-forme du monde de l'Internet. Ainsi, 1 ' architecture du réseau intelligent de communication n'est pas modifiée, le système est ouvert, multi-réseaux et multi-accês.To simplify FIG. 2, a single telephone platform 100 and a single Internet platform 200 are shown but the invention is not limited to this diagram and several telephone platforms can be connected to an Internet platform and reciprocally. Not all users of the first telephone platform 100 are necessarily connected to a single Internet platform 200, so that, in order to receive information relating to all the users assigned to it, it is important that the first 100 telephone platform can connect to several platforms in the Internet world. Thus, the architecture of the intelligent communication network is not modified, the system is open, multi-network and multi-access.
Un module 130 de référencement permet d'associer à un premier profil téléphonique d'un usager, un deuxième profil Internet de ce même usager. Le premier profil comporte des informations sur les services téléphoniques auxquels l'usager a souscrit ainsi qu'un code d'identification qui lui est attribué au moment de l'ouverture de sa ligne téléphonique via le réseau téléphonique. Les services téléphoniques sont par exemple le transfert d'appel, le renvoi vers une messagerie etc..A referencing module 130 makes it possible to associate with a first telephone profile of a user, a second Internet profile of this same user. The first profile contains information on the telephone services to which the user has subscribed as well as an identification code which is assigned to him when his telephone line is opened via the telephone network. Telephone services are for example call transfer, forwarding to messaging, etc.
Le deuxième profil Internet est transmis par la deuxième plate-forme 200 au moment de l'ouverture de la ligne au réseau à commutation de paquets et comporte des informations sur les services Internet auxquels le même usager a souscrit ainsi qu'un deuxième code d'identification qui lui est attribué au moment de l'ouverture de sa ligne au réseau à commutation de paquets . Les services Internet sont par exemple le « Chat » , l'envoi de messages écrits etc..The second Internet profile is transmitted by the second platform 200 when the line is opened to the packet-switched network and includes information on the Internet services to which the same user has subscribed as well as a second code. identification assigned to it at the time of opening its line to the packet-switched network. Internet services are for example "Chat", sending written messages, etc.
Grâce au système schématisé sur la figure 2, il est également possible d'intégrer d'autres services du monde de la téléphonie vers le monde de l'Internet d'une part, tel que la notification d'un appel téléphonique vers un terminal 250 Internet via le réseau de type Internet ou bien le renvoi de l'appel sur une autre ligne téléphonique, fixe ou mobile, lorsque la ligne appelée est occupée par une connexion Internet etc., et du monde de l'Internet vers le monde de la téléphonie d'autre part, tel que l'établissement d'appel à partir d'un terminal 250 Internet .Thanks to the system shown in FIG. 2, it is also possible to integrate other services from the world of telephony to the world of the Internet on the one hand, such as the notification of a telephone call to a terminal 250 Internet via the Internet-type network or forwarding of the call to another telephone line, fixed or mobile, when the called line is occupied by an Internet connection etc., and from the world of the Internet to the world of telephony on the other hand, such as call establishment from an Internet terminal 250.
Grâce à ce système, il est possible de véhiculer l'information de présence, gérée initialement par la plate-forme 200 de service du monde de l'Internet, vers la plate-forme 100 de service du monde de la téléphonie. Les deux plate-formes coopèrent afin de développer de nouveaux services très imbriqués de la téléphonie sur l'Internet et réciproquement .Thanks to this system, it is possible to convey the presence information, initially managed by the service platform 200 of the Internet world, to the service platform 100 of the world of telephony. The two platforms are cooperating in order to develop new, very interwoven telephony services on the Internet and vice versa.
Dès qu'un usager se connecte au réseau à commutation de paquets, son terminal 250 Internet envoie à la deuxième plate-forme 200 une information de présence signalant qu'il est connecté au réseau Internet.As soon as a user connects to the packet-switched network, his Internet terminal 250 sends presence information to the second platform 200 signaling that he is connected to the Internet network.
Selon une variante, d'autres informations relatives à la disponibilité de l'usager peuvent également être transmises avec l'information de présence. Ces informations de disponibilité reviennent pour l'usager à préciser s'il désire qu'un message lui soit affiché sur son terminal Internet lorsque quelqu'un cherche à le joindre sur sa ligne téléphonique occupée par la connexion Internet, ou s'il désire que l'appel téléphonique soit transféré vers une autre ligne téléphonique, fixe ou mobile, ou bien s'il souhaite que l'appel soit renvoyé vers une messagerie ou encore rejeté etc..According to a variant, other information relating to the availability of the user can also be transmitted with the presence information. This availability information comes back to the user to specify if he wishes a message to be displayed on his Internet terminal when someone seeks to reach him on his telephone line occupied by the Internet connection, or if he wishes that the telephone call is transferred to another telephone line, landline or mobile, or if he wishes the call to be diverted to a messaging service or rejected, etc.
L'information de présence est transmise à la première plate-forme 100 avec éventuellement l'information de disponibilité. Elle est stockée dans une mémoire 140 tampon. Cette mémoire 140 est remise à jour périodiquement, chaque fois que la deuxième plate-forme transmet un message contenant une ou plusieurs information(s) de présence. Ce message est par exemple envoyé de manière automatique et périodiquement, ou à chaque connexion/déconnexion d'un usager au réseau de type Internet .The presence information is transmitted to the first platform 100 with possibly the availability information. It is stored in a buffer memory 140. This memory 140 is updated periodically, each time the second platform transmits a message containing one or more presence information (s). This message is for example sent automatically and periodically, or each time a user connects / disconnects to the Internet-type network.
Des moyens 145 de filtrage sont en outre prévus pour commander l'envoi d'un message vers la deuxième plateforme 200 Internet en fonction des profils et de 1 ' information de présence des usagers .Filtering means 145 are further provided for controlling the sending of a message to the second Internet platform 200 according to the profiles and the presence information of the users.
Pour pouvoir coopérer, la première plate-forme 100 téléphonique doit se connecter à la deuxième plate-forme 200 de service Internet, par l'intermédiaire des moyens 110 d'accès comprenant le module adaptateur. Une procédure d'authentification est ensuite effectuée. Lorsque l'authentification est achevée, la première plate-forme 100 obtient un droit d'accès et envoie à la deuxième plate-forme 200 de service Internet une requête pour que lui soit notifiée l'information de présence de chacun de ses usagers .To be able to cooperate, the first telephone platform 100 must connect to the second Internet service platform 200, by the means 110 access including the adapter module. An authentication procedure is then performed. When the authentication is completed, the first platform 100 obtains an access right and sends to the second Internet service platform 200 a request so that the presence information of each of its users is notified to it.
Par la suite, lorsqu'un usager, référencé B sur la figure 2, se connecte au réseau Internet, il fournit simultanément son information de présence à la deuxième plate-forme 200 qui la diffuse immédiatement vers la première plate-forme 100 téléphonique qui en avait fait au préalable la demande.Subsequently, when a user, referenced B in FIG. 2, connects to the Internet, he simultaneously supplies his presence information to the second platform 200 which immediately broadcasts it to the first telephone platform 100 which in turn had previously made the request.
Lorsqu'un appel téléphonique, provenant d'un usager A, arrive sur un commutateur C de la plate-forme 100 téléphonique, deux procédures de contrôle sont mises en œuvre simultanément pour d'une part vérifier, dans le module 130 de référencement, les services auxquels l'usager B destinataire de l'appel a souscrit, et d'autre part vérifier, dans la mémoire 140 tampon, si cet usager B destinataire est connecté sur le réseau Internet.When a telephone call, coming from a user A, arrives on a switch C of the telephone platform 100, two control procedures are implemented simultaneously for, on the one hand, checking, in the referencing module 130, the services to which the user B recipient of the call has subscribed, and on the other hand to check, in the buffer memory 140, whether this user B recipient is connected to the Internet.
Ainsi, si l'usager B destinataire de l'appel est présent sur Internet et s'il a souscrit à la notification d'appel téléphonique par exemple, les moyens 145 de filtrage commandent aux moyens 110 d'accès l'envoi d'un message, via la deuxième plate-forme 200, sur le terminal 250 Internet de cet usager B pour l'alerter que quelqu'un cherche à le joindre et qu'il doit libérer sa ligne, ou liaison, téléphonique. L'usager B destinataire peut alors choisir de se déconnecter et prendre l'appel, de prendre l'appel sur une autre ligne, de refuser l'appel etc..Thus, if the user B receiving the call is present on the Internet and if he has subscribed to the telephone call notification for example, the filtering means 145 control the means 110 of access to send a message, via the second platform 200, on the Internet terminal 250 of this user B to alert him that someone is trying to reach him and that he must release his telephone line, or link. The recipient user B can then choose to disconnect and take the call, take the call on another line, refuse the call, etc.
Par contre, s'il n'a pas souscrit à la notification d'appel mais qu'il a souscrit à un renvoi automatique des appels sur une autre ligne téléphonique, fixe ou mobile, les moyens 145 de filtrage ordonnent au commutateur C de la plate-forme téléphonique de router l'appel vers cette autre ligne.On the other hand, if he has not subscribed to call notification but has subscribed to automatic call forwarding on another telephone line, fixed or mobile, the filtering means 145 order switch C to the telephone platform to route the call to this other line.
Réciproquement, un usager du réseau à commutation de paquets peut commander la numérotation d'un ou plusieurs postes 150 téléphoniques à partir de son terminal Internet afin d'établir un ou plusieurs appels téléphoniques simultanés.Conversely, a user of the packet switched network can control the numbering of one or more telephone sets 150 from his Internet terminal in order to establish one or more simultaneous telephone calls.
Le système qui vient d'être décrit n'est qu'un mode de réalisation et ne se limite en aucun cas à cet exemple. II présente une architecture ouverte, multi-accès, multi- réseaux, et multiservices qui peut être facilement adaptée aux produits du marché et intégrée à grande échelle dans les réseaux de communication existant. Ce système permet de partager une information de présence, gérée par une plate-forme du monde de l'Internet, avec une plate-forme téléphonique afin d'offrir des services de téléphonie sur Internet, comme la notification d'appel sur un terminal Internet par exemple, et réciproquement d'Internet sur la téléphonie, comme l'établissement d'appel à partir d'un terminal Internet par exemple. De manière plus générale, le système selon l'invention permet l'utilisation d'un seul numéro d'appel quel que soit le contexte d'appel. The system which has just been described is only one embodiment and is in no way limited to this example. It presents an open, multi-access, multi-network, and multi-service architecture which can be easily adapted to market products and integrated on a large scale into existing communication networks. This system makes it possible to share presence information, managed by an Internet platform, with a telephone platform in order to offer Internet telephony services, such as call notification on an Internet terminal. for example, and vice versa from the Internet over telephony, such as call establishment from an Internet terminal for example. More generally, the system according to the invention allows the use of a single call number whatever the call context.
