Abstract: A technique is provided for authentication of a user accessing an access control device. The technique includes an application server that receives a request from a communication device associated with the user or the access control device. The request contains an identifier of the communication device, an identifier of the access control device and presence data indicating that the communication device is associated with the access control device. The application server checks a database for the user's subscription, sends a response to the access control device to request the user to enter a secret code via an interface of the access control device, receives a temporary secret code generated by a service provider server if the entered secret code is correct, and sends a message containing the temporary secret code to the communication device to request the user to enter the secret code via the interface of the access control device.

Abstract: For a supervision and control of connected objects registered in an IMS network, an application server performs the following: receiving a first message containing an identifier of a connected object (CO) from a supervision server (SS), retrieving a SIP number of the CO associated with the identifier, sending a second message containing the identifier to a messaging server (MS) of the IMS network the second message further containing instructions interpreted by the MS to send a control message to an instant messaging client of the CO using the SIP number, the second message and the control message containing a command that is executed by the CO to trigger a monitoring of a sensor of the CO or the activation of a resource of the CO, receiving an update message from the CO, the update message containing a value of a sensor of the CO or an acknowledgment of said activation.

Abstract: For a safe handling of text messages (MesT) received by a communication device (CD) owned by a user, an application server (AS) receives a request (Req) from the communication device (CD), the request containing an identifier (IdCD) of the communication device and presence data (DatP) indicating that the communication device is associated with a service entity (SE) via a wireless session, the service entity (SE) being a vehicle, receives a text message (MesT) having the user as recipient, and sends a message (MesC) to a network server (NS), the message (MesC) including at least a part of the content of the text message (MesT), the network server (NS) generating a voice message (MesV) from the content of the message (MesC) and providing the voice message (MesV) via an audio call to the communication device (CD).
