摘要

To provide a technique for improving security and mobile node to improve the header compression efficiency. .. A method of the invention, the subsequent header compression if it is changed by another information, the information received packet information that allows to compress the large header than when not changed in the packet In response to the decision to have the header, including altering the information in the other information. Also, the method includes also transmits a packet containing a compressed header, and that is the compressed header at least. Another method, in response received packet is the decision to have a sequential identification in the header of the packet to change its sequence identity to a random identification; that; and the packet transmitted to the core network including. Apparatus and program product are also disclosed. .. [Selection Figure Figure 1.
