A header compression method for a wireless network, comprising: (a) determining whether a second header contains a compressed Internet Protocol version 6 (IPv6) information in a packet comprising data and at least one header containing transmission information about the data including the second header; (b) determining, when the second header contains a compressed IPv6 information, whether a mobility header follows the second header; (c) setting, when the second header is followed by the mobility header, a mobility support-indicative field of a first header containing information about the second header to indicate that the first header is followed by a compressed IPv6 header with the mobility header and a mobility header-indicative field of the second header to indicate that the second header is followed by the mobility header; (d) compressing a remainder of fields of the second header except for the mobility header-indicative field; (e) setting a mobility information-indicative field of the mobility header to indicate inclusion of mobility information; and (f) compressing a remainder of fields of the mobility header except for the mobility information-indicative field.
