US 9,426,693 B2 · Robustness header compression processing method, compressor and system

Abstract

A robustness header compression processing method, compressor and system are disclosed. The method includes: after receiving a CONTEXT_MEMORY option transmitted by a decompressor, a compressor selecting to use Profile0 to perform data compression on packets to be compressed; and after determining that a first threshold is reached by using the Profile0, the compressor performing data compression using a Profile type to which the packets to be compressed belong. In the above robustness compression processing method, compressor and system, after receiving a CONTEXT_MEMORY feedback option, a compressor selects a compression packet format Profile0 and attempts to restore normal compression and decompression after a certain period of time, thus improving efficiency and accuracy of compression and decompression as well as utilization of wireless bandwidth.

Dependent claims

A robustness header compression processing method, comprising:

receiving, by a compressor, a feedback transmitted by a decompressor, including a feedback (NACK) of a failed decompression carrying a CONTEXT_MEMORY option;
after receiving the CONTEXT_MEMORY option transmitted by the decompressor, a compressor selecting to use Profile0 to perform data compression on packets to be compressed of a packet stream;
and
after determining that a number of the uses of the Profile0 to packets of the same packet stream or time for using the Profile0 to packets of the same packet stream reaches a first threshold, the compressor performing data compression using a Profile type to which the packets to be compressed belong.
