The invention discloses a method of compressing an HTTP (hyper text transport protocol) -oriented TCP (transmission control protocol) header compression method in a 6LoWAPN (IPv-over low-power wireless personal area network). The compression and decompression operations of the TCP header are performed in all the HTTP-based communication processes in the network for saving load space, transmitting data of application layers, reducing fragmentation of data link layers and increasing communication efficiency. The method comprises the following steps: an application layer, a transmission layer and a network layer of a transmitting end complete the corresponding operations respectively, and formed IP data is delivered to an adaptation layer; the adaptation layer firstly completes compression of an IP header and an IP expansion header and then compresses the TCP header in the way of a header compression structure of Encoding and In-Line to ensure the compatibility of the compression method and the convenience in operation implementation; and formed 6LoWAPN data is delivered to a data link layer and data link frames are sent a receiving end through the data link layer and a physical layer. The receiving end decompresses the received data according to the reverse processing of the process mentioned above, and then an application layer receives HTTP data transmitted from the transmitting end.
