随着LTE网络的规模覆盖以及支持VOLTE的终端产业链的不断丰富。
VOLTE业务作为承载在4G网络的语音业务,即基于LTE的语音通信,其中心网完全舍弃了电路域(CS),供大家参考学习,使用的是基于SIP协议的全IP网络,以便进一步提高衡南县雁峰区VOLTE网络的维护质量,中国电信VOLTE业务的试商用计划在逐步推进。本文总结分析了衡南县雁峰区VOLTE网络在内部体验测试和拉网测试中的典型案例,只保留了唯一的分组域(PS),另一个则是用户间语音数据的安全。

AbstractWith the scale coverage of the LTE network and the enrichment of the terminal industry chain supporting VOLTE, China Telecom VOLTE business trial business plan is gradually advancing. VoLTE G Voice Over LTE, LTE - based voice communications, And its core network completely abandoned the circuit domain (CS), A unique grouping domain (PS), All the data, The voice service is all in the subgroup domain "solve ". Than G traditional 2 or 3 communications G, VoLTE can not only complete high-quality multimedia sessions, And can provide similar voice call management services and multimedia sessions for flexible and reasonable billing. It will become the preferred voice call service for mobile users in the future. However, VoLTE is an open network architecture, Using a full IP network based on SIP protocols, All voice calls go through packet domains rather than circuit domains, And that makes VoLTE face a lot of security problems, In particular, there are two types of security issues: one is the security of identity authentication between the end user and the business network, The other is the security of voice data between users.
VOLTE service, as a voice service carrying in the 4 G network, provides high quality audio and video calls, which also puts forward higher requirements for the quality of the IP carrying network and the cooperation and compatibility of the This paper summarizes and analyzes the typical cases of VOLTE network in Yanfeng District of Hengnan County in internal experience test and network pulling test for your reference and study in order to further improve the maintenance quality of Yanfeng District VOLTE network in Hengnan County and explore a new maintenance model.

目 录
,所有的语音电话都经由分组域而非电路域,所有的数据,对IP承载网的质量及周边网络的配合和兼容也提出更高的要求。然而,特别要指出的是两类安全问题：一个是终端用户与业务网之间身份认证的安全,提供高质量的音频视频通话,探索维护新模式。其必将成为未来移动用户首选的语音通话业务。这种特征也使得VoLTE面临诸多的安全问题,语音业务全在分组域"解决".相比于传统的2G或者3G通信技术,而且可以提供类似语音呼唤管理服务及对多媒体会话进行灵活合理的计费
