  • Method for managing variation in a data flow rate
    Patent number: 7697553
    Abstract: The present invention discloses a method of detecting overproduction of data when an H.323 endpoint is transmitting more video or other data than initially negotiated, and makes it produce less by utilizing standard flow control procedures. Flow control messages are sent periodically, incrementally instructing the H.323 endpoint to transmit lower amounts of bit rates, until the video rate received from the endpoint is equal to or lower than the initially negotiated rate, or some other fixed rate.

  • Method for bitrate adjustment
    Patent number: 7684384
    Abstract: A method and a gateway provide for down speeding the data rate at the circuit switched side of a call being translated in the gateway if the packet switched side does not have sufficient bandwidth capabilities for matching the circuit switched data rate. The gateway compares the bandwidth of the circuit switched and packet switched sides of a call after establishing the connection. If the packet switched side of the call is connected at a lower rate than the circuit switched side, e.g., because of insufficient capabilities of the packet switched endpoint, the gateway initiates a down speeding procedure at the circuit switched side. The down speeding procedure disconnects a number of B-channels of the circuit switched connection to make the call rate equal or lower than the call rate of the packet switched side of the call.
