Method and system for providing enhanced caller identification information including total call control for all received calls

A method for implementing a call control service when processing a call in a telecommunications system, the call being from a calling party at a calling communication station having a calling party directory number, the call intended for a called party at a called communication station at a called party directory number, the method comprising:

• routing the call to a terminating service switching point (SSP) associated with the called communication station;
• transmitting a termination attempt query from the terminating SSP to a service control point (SCP);
• at the SCP, in response to the termination attempt query, determining if the called party associated with the called party directory number is a subscriber to the call control service;
• if so, determining if a redirecting element field is set to a specified directory number of network equipment designated to process calls for the call control service;
• if the redirecting element field is set to the specified directory number, sending a forward call response message to the terminating SSP;
• in response to the forward call response message, routing the call from the terminating SSP to the network equipment designated to process calls for the call control service using a directory number of the called party directory number field of the forward call message;
• at the network equipment, originating a new call to the called party directory number, including formatting a setup message with a redirecting element field set to the specified directory number of the network equipment designated to process calls for the call control service;
• receiving the new call at the terminating SSP;
• in response to the received new call, transmitting a new terminating attempt query from the terminating SSP to the SCP;
• at the SCP, determining if the redirecting element field is set to the specified directory number;
• if so, sending an authorize termination message from the SCP to the terminating SSP for processing of the call to the called communication station.
