  • METHOD FOR TRANSFERRING A COMMUNICATION SESSION BETWEEN DEVICES
    Publication number: 20150245398
    Abstract: A method for transferring a communication session between a source user device and a target user device in a communication network, where the communication session is established between the source user device and a server is proposed. An identifier of a user device is determined. A session modification request is then sent from the source user device to the server, where the request includes the identifier of the target user device. A capability of the target user device to handle the communication session is then checked. Next, if the target user device is capable of handling the communication session a further communication session between the server and the target user device is established.
