VoLTE异厂家组网方案研究

VoLTE 是 LTE(Long Term Evolution)语音业务的目标方案, 需要 IMS(IP Multimedia Subsystem)系统提供业务支撑, VoLTE 核心网的单厂家组网方案, 短时期内满足了呼叫业务的端到端测试, 但也容易受单个厂家的技术限制。 从现有 VoLTE 单厂家单域组网的实际情况出发, 分析 IMS 核心网网元异厂家设备间组网方案的可行性, 并提出多种组网方案的分析和建议。 综合无线系统、 HSS/ HLR(Home Subscriber Server/ Home LocationRegister)、 分组域等因素的影响, 分业务区引入不同厂家 VoLTE IMS 设备组网, 在控制网络建设投资的前提下, 既能保证新技术和新业务的快速上线, 也能为网络的安全性、 扩展性带来保障。 对 VoLTE 的扩大部署及各运营商的实际网络建设提供指导意见。

VoLTE Different Manufacturers Network Scheme

VoLTE is the goal of the program for LTE voice service, it needs IMS system to provide operational support,The single factory networking solution of VoLTE core network, satisfied ending to ending test call service in short time, but also easy to be limited by single manufacturer‘’s technical constraints, integrating wireless systems、 HSS/ HLR, packet domain and other considerations, a reasonable choice of equipment from different manufacturers VoLTE IMS network by different area, under the control of network construction investment premise, both to ensure the rapid on-line services, but also to bring security for network security. From the actual situation existing VoLTE single factory single-domain network, analyzes the feasibility of IMS core network element between different manufacturers of networking equipment programs, and a variety of analysis and recommendations networking schemes, in order for the VoLTE expand the deployment of reference and to provide guidance for the actual construction of the respective network operators.
