  • Methods and systems for mobile application part (MAP) screening in transit networks
    Patent number: 7403537
    Abstract: A method for screening mobile application part (MAP) messages in a transit network is provided. Signaling messages are received from a first network. SCCP called party address information is extracted from each signaling message. If the called party address matches first SCCP screening criteria, it is determined whether the signaling message is a targeted MAP message type. If the signaling message is a targeted MAP message type, a screening action is performed. Different MAP screening criteria may be applied for different destination networks.
