    Abstract: The present invention discloses a method and a system for determining IP bearer optimization based on virtual media gateway. The method includes the following steps: when establishing an IP bearer for a first terminal, a first virtual media gateway determines that the first terminal and a second terminal are located at the same physical media gateway according to bearer information of the second terminal at an opposite end; the first virtual media gateway interacts with a second virtual media gateway to which the second terminal belongs, and a master virtual media gateway determines that both the first terminal and the second terminal can perform IP bearer optimization, wherein the master virtual media gateway is one of the first virtual media gateway and the second virtual media gateway. The present invention can avoid the waste of network resources, reduce the network delay, and improve the voice quality.
