System for managing voice over internet protocol communications in a network
First Claim
1. A system for preventing wireless devices from hosting voice calls on a data communication connection, comprising:
- network for generating radio frequency communication signals to communicate with a plurality of wireless devices and a data communication network, to enable said wireless device to establish data communication sessions, through said network, with servers connected to said data communication network; and
voice call prevention means, connected to said network for inhibiting said wireless devices from hosting a voice call on a data communication connection through said network, comprising;
data monitoring, responsive to one of said wireless devices engaged in a data communication session on a data communication connection through said network, for determining weather said data communication session comprises a voice call, andcall termination, responsive to detection of the presence of a voice call, for causing termination of said voice call, comprisingpacket processing, responsive to said data communication connection, for controllably adjusting processing of said packet data traffic carried on said data communication connection to realize a value of at least one data transmission characteristic of said packet data traffic that fails to correspond to a value of at least one data transmission characteristic of a voice call.

Abstract
The VoIP Management System is capable of identifying voice-based wireless devices and denying wireless communication services to these devices. The VoIP Management System also identifies VoIP packet data traffic, and this communication connection can be denied. The VoIP Management System can also identify encrypted VoIP packet data traffic (for a unique Source -Destination IP pair) based upon VoIP packet data traffic characteristics: packet timing, packet rate, and packet size, since VoIP services have a distinct packet data traffic pattern. When a VoIP call is detected, the VoIP Management System disrupts the identified VoIP packet data traffic, without modifying the packet data content, such as by adding sufficient latency to the Packet Data Unit of the packet data traffic to make the VoIP services unusable.

10. A method for preventing wireless device from hosting voice calls on a data communication connection, comprising:
-
generating in a network radio frequency communication signals to communicate with said a plurality of wireless devices and a data communication network, to enable said wireless devices to establish data communication sessions, through said network, with servers connected to said data communication network; and inhibiting said wireless devices from hosting a voice call on a data communication connection said network, comprising; determining, in response to one of said wireless devices engaged in a data communication session on a data communication connection through said network, whether said data communication session comprises a voice call, and terminating, in response to detection of the presence of a voice call, said voice call, controllably adjusting processing, in response to said data communication, connection of packet data traffic carried on said data communication connection to realize a value of at least one data transmission characteristic of said packet data traffic that fails to correspond to a value of at least one data transmission characteristic of a voice call. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
