ABSTRACT:
In this communications architecture, a receiver or a receiver control entity acting on behalf of the receiver or a group of receivers, controls the communication of voice, data, or video from individual senders. This is accomplished by placing a Registrar between the senders and receivers. Upon an authorized request from a sender to access a receiver, the Registrar issues a vector to the sender and stores the vector in a database. The vector uniquely identifies both the sender and the receiver. Each time the sender wishes to make a voice call or send a data packet or a video transmission to a particular receiver, the corresponding vector is sent to the switch as the receiver's address. The switch sends the vector to the Registrar for call treatment instruction. A control computer in the Registrar queries the Registrar's database to see whether the receiver identified by the vector has sent the Registrar a call treatment instruction to supersede the default "valid" state and to determine the receiving device address to which the call, packet or video transmission should be sent. The Registrar's control computer then sends an appropriate instruction to the switch, and the switch directs the call, packet or video transmission to the device specified by the receiver.
