The invention discloses
data transmission equipment, a
data transmission method and a communication
system, and relates to the communication field, solving the problems of higher
wireless network operation and maintenance cost and poor-quality
wireless broadband business service. The
data transmission equipment provided by the invention is positioned on an IP metropolitan-
area network node or on an optical line terminal of a
wireless access network, and comprises a first service bypass
processing module and a second service bypass
processing module, wherein, the first service bypass
processing module is used for receiving uplink pocket service data sent by
user equipment (UE), for determining that the uplink pocket service needs diversion according to the preset service diversion strategies, and for directly diverting the unlink pocket data to a
public data network PDN through a preset local Gi interface; and / or the second service bypass processing module is used for directly receiving the downlink pocket service data sent to the UE by PDN from the Gi interface, for transmitting the downlink pocket service data to the UE. The embodiment of the invention can be used in
wireless communication systems, such as 3G or LTE and the like.
