摘要
LTE网络建设初期,无线覆盖不连续,需要进行2/3/4G环境下的话音呼叫切换。为保证VoLTE话音业务的连续性,需要进行电路域eMSC改造。根据运营商市场策略,4G时代需严格控制电路域改造规模,提高投资效益。因此,针对eMSC改造方案需要结合政策性、经济性、技术性等因素提出切实可行的改造方案。本文将从方案原理、现网改造关键需求、后续存在问题等方面进行分析,得出eMSC改造方案,并给出适合现网的应用部署建议。
When LTE network constructs erarly, wireless coverage is not continuous, the need for a voice call is switched 2G / 3G and 4G environments o In order to ensure the continuity of VoLTE voice services, it needs to circuit domain eMSC trans- formation. According to the carrier market strategy, 4G era should be strictly controlled circuit scale transform domain, and improve investment efficiency. Thus, rehabilitation programs for eMSC policy requires a combination of economic, technical and other factors put forward practical rehabilitation programs. In this paper, the principle of the transformation from the scheme, existing network key needs, follow-existence problems were analyzed, results eMSC rehabilitation programs, and given the current network for application deployment recommendations.
