A net accessing optimization method for virtual media gateway (5000, 5001), which can solve the problems of resource waste of the transcoder (TC), resource waste of the network transmission and the voice quality reduction in the prior art. This method includes: the network entity (501), which controls the virtual media gateway (5000, 5001), instructs the virtual media gateway (5000, 5001) in the same media gateway (500) to activate optimization for the appointed terminations (T1, T4) in the appointed physical contexts (C1, C2), respectively; after confirming there is connection relation between the appointed physical contexts (C1, C2), said media gateway (500) causes the appointed terminations (T1, T4) to be connected directly. And a media gateway (500) and a network system thereof. |
