Abstract: An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which re-ceives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S--CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the IN-VITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept. A method for supporting a can by a telecommunications node.

Abstract: In a radio telecommunication system, the performance of a mobile unit can be significantly improved during a hand-over procedure by reusing existing security associations that correspond to the mobile unit. By reusing existing security associations, a mobile unit can begin secure communications immediately following the hand-over. Otherwise, and in accordance with conventional practice, the mobile unit will have to undertake the time consuming task of renegotiating the required security associations, before it can begin transmitting and receiving secure communications.

Abstract: Un método para conseguirrealizar en una red de telecomunicación inalámbrica el traspaso seguro de un terminal móvil (MT) desde un primer punto de acceso (APOLD) a un segundo punto de acceso (APNEW), en el que el primer punto de acceso (APOLD) y el segundo punto de acceso (APNEW) están físicamente conectados a través de una red fija, comprendiendo dicho método los pasos de: transmitir una señal de seguridad (S/TOKEN) desde el primer punto de acceso al terminal móvil (MT) a través depor*** un interfaz de radio; transmitir la señal de seguridad (S/TOKEN) desde el terminal móvil (MT) al segundo punto de acceso a través delpor*** el interfaz de radio; transmitir la señal de seguridad (S/TOKEN) desde el primer punto de acceso (APOLD) al segundo punto de acceso (APNEW) a través de la red fija; y establecer un enlace de comunicación entre el terminal móvil (MT) y el segundo punto de acceso (APNEW), para conseguir un traspaso seguro si el segundo punto de acceso (APNEW) determina que la señal de seguridad (S/TOKEN) recibida desde el terminal móvil (MT) coincide*** con la señal de seguridad (S/TOKEN) recibida del primer punto de acceso (APOLD).

Abstract: A method and arrangement in a multimedia gateway connected to a multimedia service network, for providing access to multimedia services for communication devices connected to a private network. In the multimedia gateway, a communication unit receives a request from a device in the private network for a public identity associated with the multimedia gateway. An identity manager then selects and allocates an associated public identity from a pool of public identities associated with the multimedia gateway which have been predefined as valid in the multimedia service network. The communication unit then registers the device by activating the allocated associated public identity in the multimedia service network. Thereby, the multimedia gateway can establish a multimedia session on behalf of the device, using the allocated associated public identity.

Abstract: In a mobile, wireless telecommunications network, communications relating to a mobile terminal can be protected during a handover of the mobile terminal from a first access point to a second access point. This may be accomplished by transmitting a security token from the first access point to the mobile terminal, and then from the mobile terminal to the second access point, over the radio interface. Thereafter, the security token is transmitted from the first access point to the second access point through the fixed network to which both the first and the second access points are connected. The communications link between the mobile terminal and the second access point needed to achieve secure handover is then established only if the second access point determines that the security token received from the mobile terminal matches the security token received from the first access point.
