随着移动网络的发展,现网部分HSS(归属签约用户服务器)设备已无法满足用户和新业务发展的需求,需进行新建和替换。由于集团高清语音VoL TE(LTE语音)业务的快速商用,因此HSS设备搬迁替换除涉及移动用户签约数据迁移外,还需要考虑VoL TE用户数据的搬迁。本文结合国内首例VoL TE用户数据的搬迁实施案例,在梳理分析现有HSS设备VoL TE用户数据搬迁技术方案的基础上,提出了优化解决方案,以提升用户数据迁移的效率。
With the development of mobile networks, some existing HSS (Home Subscriber Server) devices in the existing network are unable to meet the needs of users and new business development, and need to be newly built and replaced. Due to the rapid commercial use of VoL TE (Voice over LTE) services of the Group, the relocation of HSS equipment involves the relocation of VoL TE user data in addition to the subscription data migration of mobile users. Based on the case study of relocating the first VoL TE user data in China, this paper presents an optimization solution to improve the efficiency of user data migration based on combing and analyzing the solution of relocating VoL TE user data in existing HSS devices.
