The technical solution provided by the present invention controls the MG to report the timestamp of an event; enables the MGC or other applications that require the timestamp of the event to determine the actual time when the event appears according to the obtained timestamp; and controls the reported event not to include the timestamp if the MGC or other applications do not need the timestamp of the event, thus saving the bandwidth resources and other system resources.

Abstract: The present disclosure discloses a method, system, and apparatus for filtering packets. The method includes setting packet filtering information that uniquely identifies the basic characteristics of a media stream in an Internet Protocol version 6 (IPv6)-based packet header.

Based on the obtained capability, the MGC determines and controls the implementation of the internal connection, or the MG determines and controls the implementation of the internal connection itself.

The MGC can also control the MG's capability of determining and realizing the internal connection by itself based on the service characteristics.

Abstract: A media gateway (MG) and method for reporting the termination statistic parameter value, the media gateway controller (MGC) may obtain the statistic parameter value of the termination in real-time with the little performance expense in the frame of media gateway control protocol. The present invention extends one event whose parameters contain the statistic parameter identifier using the event mechanism of media gateway control protocol, reporting the current value of the corresponding statistic parameter according to the statistic parameter identifier in the parameters when the event is triggered. Various optional trigger conditions may be set in the event parameters, including the duration for reporting, the period for reporting, the specific statistic exceeding certain extremum etc. as well as any combination thereof. While the statistic parameter in the event parameters is reported, maintains the statistic parameter value to prevent from reporting affect, or resets the statistic parameter value.

Abstract: The present invention relates to a method and apparatus for adjusting the value of the statistic parameter so as to enable an MGC dynamically adjust the statistic parameter under H.248 framework. The method extends the H.248 protocol. The MGC sends adjustment information to the MG. The MG adjusts the value of the specified statistic parameter in a specified adjustment manner according to the adjustment information. The adjustment manner may be direct value assignment or one adjustment operation executed by the MG combining with a local preset parameter. If the adjustment information can not be recognized or supported by the MG, or the adjustment information is not suitable for the statistic parameter, the MG returns corresponding error information to the MGC. The adjustment to the statistic parameter value by the MGC may be issued to the MG for execution at the same time with other operations such as audit.
