A Mobility Management Method for Space-Earth Integration Network Based on Identity Mapping System

The space-earth integration network based on the identity mapping system can take into account both the advantages of the space-earth integration network and the identity mapping network. It can achieve a wide range of seamless coverage and information exchange and solve the ambiguity problem of IP address caused by traditional network through the separation of location and identity. Due to the time variation of the space-earth integration network framework and the difference between the identity mapping system and the traditional network, the current satellite network mobility management methods have the problems of high handover delay and large packet loss rate. Aiming at this phenomenon, this paper proposes a mobility management method for realizing the low delay and the high-reliability on the space-earth integration network. The results of simulation experiments show that the mobility management method solves the problems of high overhead and low reliability caused by mobile handover in the space-earth integration network based on the identity mapping system, and ensures the stability of the space-earth integration network.
