Novel device for network communication technology

The invention discloses a novel device for network communication technology. Through the adoption of the device, a plurality of GPRS users can share one wireless communication channel. The device has the following characteristics: (1) a wide network access range: network cabling is unnecessary on a borne and established wireless communication network, a remote access network function can be conveniently provided for each user using mobile terminals such as a mobile phone, a PAD and the like; (2) a high transmission rate: the transmission rate of the GPRS technology can achieve ~, J57.6Kbit/s, theoretically, the highest transmission rate can achieve ~ljlT1.2Kbps, and is more than ten times of the data exchange data in a GSM network, and the transmission efficiency is high; (3) real-time online performance: user equipment can access the network resource in real time as long as the user equipment is always in the online status; (4) automatic switching of data and voice service: a terminal user is capable of freely switching between the data service and the voice service at the same time while receiving and sending the network data; (5) billing by flow: the GPRS can charge according to the data amount of the data packets sent and received by a terminal user, even though the user is online for a long time, the charge cannot be produced if the data transmission is inexistent.
