With the mobile core network gradually expand the scale , the number of mobile users is growing . The rapid growth of mobile network traffic . At the same time, put a higher demand for network security and stability . HLR as important in the mobile core network equipment , although there are disaster recovery system , but the speed of disaster response , disaster recovery, economy, reliability , etc. are unable to adapt to the market demand for business development . In order to provide a more secure and stable network services to the majority of mobile users , and to further reduce the last stage of the high traffic growth is likely to be the impact on network stability , improve mobile HLR disaster recovery system to force can not be delayed . This paper first introduces the subject of background , the status of the development of mobile networks , and the practical needs of the core network to establish an effective disaster recovery system . Secondly, the communication network disaster recovery theory and mobile communication technology system research, detailed analysis of the the core network HLR device disaster recovery basic ideas and clues from two angles of the reliability theory and technology implementation , and is determined by comparing the HLR NX content disaster applicability of the technology . Then, from a few aspects of a detailed analysis of the key technologies involved in the HLR NX disaster recovery , based on the technology of the existing network Ericsson , Nokia HLR were presented the NX disaster recovery programs, as well as the way to achieve perfect mobile HLR equipment disaster recovery system . Finally, the research projects are summarized , and look forward to the future direction of development of the HLR disaster recovery technology .
