我国的移动通信网络技术历经多年的技术更新和演变,已发展成以VoLTE技术为代表的第四代移动通信技术。目前,VoLTE技术已日益受到重视和广泛应用。VoLTE技术的语音业务优势是4G移动通信时代的最大亮点,它具有比电路域回落方案(CSFB)和终端双待方案更明显的优势。在应用中,VoLTE技术经过了热点覆盖发展期、LTE网络连续覆盖发展期和LTE网络全覆盖发展期三个阶段。VoLTE技术在用户体验、语音接续力、应用范围与业务特性、频谱利用率与覆盖率以及应用成本等方面具有更大的网络优势。
After many years of technological innovation and evolution, China’s mobile communication network technology has evolved into the fourth generation of mobile communication technology represented by VoLTE technology. At present, VoLTE technology has been increasingly valued and widely used. VoLTE technology voice business advantage is the biggest highlight of 4G mobile communications era, it has more obvious than the circuit domain fallback solution (CSFB) and terminal dual standby solution more obvious advantages. In the application, VoLTE technology has gone through three stages of hotspot coverage development, LTE network coverage development and LTE network full coverage development. VoLTE technology has greater network advantages in terms of user experience, voice continuity, application area and service characteristics, spectrum utilization and coverage, and application cost.
