Patent ID: 10681143

Abstract:
A system, method, node, user equipment and computer program for establishment of a secure connection between a user equipment (100) and a media gateway (130) at setup of a communication session with another party (150) is described. The media gateway (130) is controlled by a control server (120). The control server (120) receives a communication session setup request from the user equipment (100) and determines an indication of a security certificate of the media gateway (130). The control server (120) then sends the indication of the security certificate of the media gateway (130) to the user equipment (100), wherein the indication is sent before or in parallel to sending the communication session setup request towards said other party (150). The user equipment (100) then initiates a negotiation of security related parameters, based on the received indication of the security certificate of the media gateway (130). Then the secure connection between the user equipment (100) and the media gateway (130) is established, utilizing the negotiated security related parameters.
