Abstract
A method for data transmission in a system including a first base station controller (BSC) and a first media gateway (MGW) is provided. The first MGW receives from the first BSC an internet protocol (IP) packet with an encoded voice payload encapsulated therein. The encoded voice payload is obtained by the first BSC by removing a Transcoder and Rate Adaptation Unit (TRAU) encapsulation from data received from a base transceiver station (BTS). The first MGW determines a codec type of the encoded voice payload is the same as a codec type adopted by a second BSC connected to the first MGW or is the same as a codec type adopted by a second MGW connected to the first MGW. The first MGW sends the encoded voice payload to the second BSC or the second MGW after the determination.
