As the demand for high quality IP services for mobile users is increasing, the problem of bandwidth limitation and unreliability of wireless links is faced. Additional requirements are imposed for real-time audio and video over cellular networks. Applications such as Voice over IP or video conferencing are delay sensitive. To use the precisions bandwidth efficiently, the voice payload and IP packet headers are compressed. However, using the conventional IP header compression schemes, the stringent latency budget of real-time applications can not be met. It happens due to the low responsiveness of the omnipresent cellular networks where the compressor entity is located at the concentrator node and not at the access point itself. Delayed context update leads to appearance of the error burst that can not be hidden from a user by CODECs. To overcome the above-mentioned problems and to make it attractive to employ header compression in cellular networks, we propose a new context repair mechanism that is based on the concept of micro cooperation.
