The present invention generally relates to the domain of methods for interacting between an operator of telecommunication network and a user. More precisely it concerns the domain of mobile phones network and TV network.

It is known for a TV network to keep a profile of its subscribers by collecting information about programs actually watched by subscribers, some information about their liking and habits. From these profiles the operator is able to select dedicated content, for example advertisement, targeted for a particular subscriber.

One problem that arises is that one subscription is generally done for a home where are living several people. Therefore the subscriber profile corresponds to a mean of taste and habits of several people without possibility to know who is actually watching a given program in front of the TV.

In this document, we will gather under the generic name of multimedia player all devices able to display broadcasted content. Are comprised the TV sets, personal computers, tablets, netbooks, some game consoles, etc. These multimedia players are able to receive broadcast content on several kinds of networks, like satellite networks, cable networks, or now IP networks like Internet. On one hand, multimedia players are now often connected to the local network in the home with connectivity to other user appliance and to the network and more particularly to the operator service. On another hand, the user is using mobile terminals, like mobile phones, tablet computers or others. These mobile terminals are often able to connect to the mobile phone communication network to get connectivity in mobility and to the local network when being at home.

The invention aims to solve the problem of identifying users actually watching a program on a TV set or alike to be able to distribute to them some accurately targeted content. To achieve this, the connected media player discovers the user terminals also connected to the local network. By obtaining the user id in a secured manner, or not, used by the terminal to connect to the mobile network and sending it to the operator, the latter is able to establish the link between the watched broadcast program and who is actually watching it.

The invention concerns a method for interacting between an operator and at least one user, the operator operating a first communication network, the user owning a terminal to connect to said first communication network using a user identifier, the operator operating a broadcast network to broadcast multimedia content to multimedia players, said multimedia players and said terminal being able to connect to a local network, said local network being connected to the operator using a second communication network, which comprises by a multimedia player connected to the local network a step of playing broadcast multimedia content sent by the operator; a step of discovering at least one user terminal connected to the local network; a step of sending a request for a user identifier to discovered user terminal; a step of receiving from discovered user terminal the user identifier used by the terminal to connect to said first connection network and a step of sending to the operator said user identifier by the second network.

Fig. 1 illustrates the global architecture of the system in an exemplary embodiment. Bloc 1.1 represents the service of the operator. It should be understood what is called the operator in this document. The operator represents one or several operators that are operating networks for the benefit of end users. As the invention implies the use of several kinds of networks, these are operated in a coordinated manner. This coordination could be done by one operator in charge of all these networks or by several operators, each in charge of one or several networks, and working under cooperation agreement. As these aspects are commercial ones and not technical ones, we use the generic term of operator to indicate the plurality of entity in charge of used networks as there was only one operator which could not be always the case. The service of the operator is in charge of a first network, referenced 1.7. This first network is typically the mobile phone network but this is not mandatory. This first network aims at being used in mobility by users terminals 1.5 or 1.6. These terminals are personal mobile terminals that are typically used by only their owner. Some examples of these personal mobile terminals are mobile phones, tablet personal computers, personal digital assistants, game consoles and so on, as soon as they comprise some connection means to connect to the first communication network.

Connection to such network needs credential to establish the connection. In case of typical mobile phone network, a user identifier called IMSI standing for International Mobile Subscriber Identifier is typically used. This user identifier uniquely identifies any mobile phone subscriber on the planet. Each mobile phone network operator is able to link this identifier to the account of its subscribers. The user identifier is typically stored in the smart card holding account credentials called the SIM, standing for Subscriber Identity Module, card used by the terminal.

These terminals are more and more often able to connect to other kinds of communication networks. More specifically, many of these terminals are able today to connect to WLAN networks like WiFi networks. Thanks to these WLAN connection means, they can connect to local home networks like network 1.4 on Fig. 1 . Advantageously, the operator can supply its subscribers with WLAN enabled SIM card to ensure that whatever terminal is used, the terminal will have WLAN connectivity thanks to the SIM card itself. This option allows also guaranteeing some security due to the fact that both network interfaces, the mobile network one and the WLAN one, are operated in the same secure component, the SIM card. One example of this kind of SIM card is the "ConnectSIM" card by SAFRAN MORPHO company.

In the user home, the local network 1.4 is typically connected to a generic communication network 1.9, typically the Internet network, using a home gateway 1.2. This generic communication network allows, among others, to connect to the operator service 1.1.

Some media players 1.3 could be also connected to the local network 1.4. These media players, like personal computers, connected TV sets, TV plus set top box sets and so on are able to receive broadcasted multimedia content. The operator broadcasts the content using a broadcast network 1.8. This network can use satellite network, cable network or event IP network. This means that the broadcast network 1.8 can be the generic communication network 1.9.

To be able to send targeted content, like for example advertisement, to their subscribers, the TV operators are used to store profiles of these subscribers. In these profiles they can store preferences, tastes or statistics about usage. The problem is that these profiles are associated to the TV subscriber. Typically, there is one subscription for a home meaning for the whole family.

The exemplary embodiment of the invention is based on the specific implementation shown on Fig. 2. On this figure, one can see the multimedia player 2.1. It comprises WLAN connection means 2.2 to connect to home local network 2.4. These means could consist in an Ethernet plug or WiFi wireless connection means or whatever technology. The multimedia player also comprises a dedicated module 2.3 able to communicate over the local network.

Also connected to the local network is the terminal 2.5, which is typically a mobile phone while it could be a tablet pc for example. In the exemplary embodiment, both WLAN connection means and mobile phone network connection means are embedded in the SIM card 2.6. The electronic component 2.7 of the SIM card comprises the classical secure element 2.9 running telecom applications. The WLAN slave element 2.8 is fully controlled by the secure element 2.9. A Power management system 2.10 is providing energy to the WLAN element, enough to transmit burst over the air.

The way the invention is working is explained in relation with Fig. 3 and Fig. 4. At first we suppose that the media player is switched on and is playing a broadcast program. It is playing multimedia content, this is step 3.1. As the media player is connected to the local network, it is able to achieve discovery steps on this network. This is step 3.2. We now suppose that a first user is entering the home and begins to watch the content displayed by the media player. His terminal connects to the local network using its WLAN connection means. Once connected, thanks to the discovering capabilities of the media player, the latter is able to detect the connected terminal in step 3.2. The discovery step is implemented using DLNA (Digital Living Network Alliance) capabilities in the exemplary embodiment. Some other protocols could be used as, for example, the SSDP (Simple Service Discovery Protocol) included in UPnP (Universal Plug and Play) protocols.

When the terminal is discovered, the media player sends a request to the terminal in order to ask for the user identifier used by this terminal on the mobile network, step 3.3. Advantageously in the exemplary embodiment this identifier is the

IMSI of the user, but any user identifier allowing the operator to uniquely identify the actual user owning the terminal could be used.

When receiving the request in step 4.1, the terminal may ask the user in step 4.2 if he gives his agreement to the sending of its identifier to the media player and therefore to the operator service. This could be done by asking him if he wants to connect to the service. If he refuses, then the process stops there. If he gives his agreement, then the terminal sends its response containing the identifier in step 4.3 back to the media player. Depending on the politic implemented by the operator, the response could be sent directly in silent mode without asking the user for his agreement. In some cases also, the agreement could be asked for once and after while, the response is given silently automatically each time the media player is asking for it.

Furthermore, the user agreement delivery can be more secured and then the user will have to enter a password to unlock the service. Advantageously, for example to secure access to sensitive services, a strong mutual authentication could be required between the multimedia player and the terminal before allowing the terminal to send the user ID to the player.

When receiving this response containing the user identifier in step 3.4, the media player is sending it back to the operator service in step 3.5. This communication is using typically the generic communication network 1.9 but is not limited to. Advantageously this message could also contain some information like the program actually displayed by the media player. This way, the operator gets the information on who is actually watching the program in front of the media player.

The operator could use this information in many ways. The first option is to consolidate the user profile with the information on the program he is watching. The second option is to use his profile to select dedicated content targeted for the user.

This could be some advertisement related to the program or to the taste of the user.

The media player then receives the dedicated content sent by the operator in step 3.7.

Depending on the kind of content, the media player could display the dedicated content on the screen, step 3.9 or push the dedicated content to the terminal in step 3.8.

In some use cases, the media player could also generate some messages, step 3.6, for the user to be displayed on the terminal. For example, the media player can generate some short text messages, like SMS, to be sent to the terminal in some interaction scenario.

Alternatively, the operator can also send the dedicated content or some messages directly to the terminal using the mobile phone network.

When receiving the dedicated content from the media player or directly from the operator, the terminal displays it in step 4.4.

When receiving some messages from the media player or from the operator, the terminal displays the message in step 4.5.

This interaction method could be used, as explained to send targeted advertisement, but it could also be used to achieve interaction related to the broadcast program. For example, it could be used to propose some bet to the user related to a sport program or to propose some product to buy related to the program and so on.
