Header decompression apparatus for packet transmission, updates reference information based on update information received from header compressor in response to transmitted update information

摘要

A storage unit stores the number of errors detected in the packet having a decompressed header. An update request transmitting unit transmits update information to a header compressor (607), based on the number of errors. A reference information manager (605) updates the stored reference information, based on the update information received from the header compressor in response to transmitted update information. Independent claims are also included for the following: (a) Header decompression method; (b) Computer-readable medium storing header decompression program; (c) Header decompression program.
