摘要：The present invention discloses a data transmission device and method and acommunication system, which relate to the field of communications technologies, to
solve the problem of high operation and maintenance cost of a radio network and lowquality of service of a radio broadband service in the prior art. The data transmissiondevice provided in the present invention is located on an IP metropolitan area networknode or on an optical line terminal of a radio access network and includes: a first servicebypass processing module, configured to receive uplink packet service data sent by auser equipment, determine, according to a preset service distribution policy, that theuplink packet service data needs distribution, and directly send the uplink packet servicedata to a public data network PDN through a locally preset Gi interface; and/or a secondservice bypass processing module, configured to directly receive, through the Gi
interface, downlink packet service data sent by the PDN to the UE and send the downlinkpacket service data to the UE. The embodiments of the present invention are applicableto radio communication systems such 3G or LTE.
