Abstract
Methods and related apparatus are described of operating a transaction proxy to act as a conduit for a structured transaction, such as Transaction Capabilities Application Part (TCAP) structured dialog between a first transaction peer, for instance an Short Message Service Center (SMSC), and a second transaction peer, for instance an Mobile Switching Center (MSC). The method comprises the steps of: receiving a begin message; determining an address of the first transaction peer from the begin message; responding to the begin message by sending a continue message to the first transaction peer; and, if no abort message is received from the first transaction peer, forwarding the begin message to the second transaction peer. Embodiments of the invention employ the techniques for filtering mobile terminating forward Short Message (mt-forwardSM) messages containing spoofed addresses in Global System for Mobile Communications (GSM) systems.
