GTP信令规定了移动台MS接入GPRS网络的隧道控制和管理协议要求，信令主要执行建立、修改和删除隧道的功能。在用户面，GTP利用GSN之间建立的隧道传送用户数据分组。-GTP signaling provides GPRS mobile station MS network access control and management of the tunnel requirements in the agreement, signaling the main executive to establish, modify and delete functions of the tunnel. In the user plane, GTP using GSN tunnel established between the transmission of user data packet.

利用哈夫曼编码进行通信可以大大提高通信信道利用率，缩短信息传输时间，降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码；在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双工传输信息的信道），每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
