Method and apparatus for internet protocol headers compression initialization

Are here providing is in IP network and quick AND said preset the Internet protocol for compression node, the method and IP manager. The present invention how to exchange IP packet between the IP network at least two nodes in turn arranged in the dipole session, how front completing the session arranged on at least two node initial to for compression environment the upper part, and how to solve compression and at least two nodes application and IP packet of the second switching. In one embodiment of the present invention can selection, further how invention claims an IP to the group - comprising a withdraw the information on IP network first at least two node and IP packet between the IP network at least two nodes.
