APPARATUS AND METHOD FOR IMPLEMENTING TEXT BASED COMPRESSION USING CACHE AND BLANK APPROACH

摘要

Compress and have compressed device and method text-based message. A kind of TCCB layers 114,115 are added to mobile device 100 and P-CSCF 102. Airtight transmission is called TCCB compression methods to be comprised in message removing the header information of all redundancies and is sent. When TCCB compression methods detect the content particular sequence identical as what is sent or received in the past of those headers, then this header content of TCCB methods blank. It is mounted with reception device, the free header content of band is received when TCCB layers, TCCB decompression methods are called, with reproducing head from its cache 115,127.
