Abstract:

A context transfer scheme for header compression in LTE (long term evolution) networks is introduced. The proposed scheme can reduce packet cost and signaling message delay in wireless radio links. A detailed description of the context transfer scheme is presented, which includes signaling message handling, parameter rebuilding, and state migration. The simulation analyses show the efficiency of the proposed scheme, and the scheme is suitable for voice-based wireless networks.

Key words: LTE network, header compression, context transfer
