Abstract: According to the present invention a telecommunication network with a first domain (PLMN-A) comprising at least one mobile application part protocol instance is connected to a gateway node (MSEGA) which is adapted to send and receive mobile application part messages and which is connectable to a second domain. The telecommunication network is remarkable in that the gateway node (MSEGA) is adapted to receive a mobile application part message from the first domain, to convert the received mobile application part message obtaining a secured mobile application part message, and to send the obtained message to the second domain. The gateway node (MSEGA) is further adapted to receive a secured mobile application part message from the second domain, to extract an unsecured mobile application part message from the received secured mobile application part message and to send the extracted message to the first domain.

Abstract: A SS7 network component (e.g., Signaling Transfer Point (STP)) and a method are described herein which function to add a security parameter and if desired encrypt the user data in a traditional Signaling Connection Control Part (SCCP) message to create a secure SCCP message that can be safely transmitted through one or more transport SS7 networks to a destination SS7 network. The destination SS7 network has a SS7 network component (e.g., STP) that can function to transform the secure SCCP message back into the traditional SCCP message.
