    摘要： In a telecommunications network (1), a signal transfer point (10) receives an Initial Address Message (IAM) generated by an originating service switching point (12) according to a call from an originating subscriber (20). The IAM includes a destination number associated with a destination subscriber (22). If the destination number has not been ported, the signal transfer point (10) sends a return message to the originating service switching point (12) indicating that no changes are to be made to the IAM. As a result, the originating service switching point (12) forwards the IAM to a destination service switching point (13) for processing of the call. If the destination number has been ported, the signal transfer point (10) performs a local number portability look-up in a database (24). The signal transfer point (10) obtains a redirection number from the database (24) for transfer in a return message to the originating service switching point (16). The originating service switching point (12) includes the redirection number in the IAM message transferred to the destination service switching point (13).

    摘要： An application server enables a secure network interaction. The application server receives a request for the secure network interaction from a third-party server. In response, the application server determines a security procedure, such as an authentication procedure, and a client corresponding to the secure network interaction. The client includes a secure desktop agent (SDA). The application server sends a message to the client that activates the SDA. The SDA establishes a secure connection with the application server. The SDA receives user credentials in a secure desktop environment and transmits them to the application server over the secure connection. The application verifies the user credentials and sends a digitally-signed authenticated response to the third-party server.
