5G新通话业务,具备开放的应用平台、可视化人机交互等特点,可极大提升用户通话体验,是电信运营商基于5G网络对传统电信业务开展创新的重要尝试.如何对这一创新业务进行计费已成为业务成功发展的关键问题.对 5G新通话进行介绍,并通过分析其业务特征及现有的计费模式,给出 5G新通话发展不同阶段的计费模式建议.

以太网中的多种协议和应用都对网络中报文的顺序敏感,网络中出现大量乱序报文会导致接收端重新排序从而大大降低性能,或者导致实时流媒体应用的服务质量下降.文章对报文顺序性的度量标准和检查方法进行研究,并在FPGA上设计并实现了针对100GE链路的报文顺序性检查功能.

近年来移动分组数据业务计费方面的投诉层出不穷,引起了全社会大规模的舆论关注.移动分组数据业务计费检测能够提升电信企业的计费准确性,确保消费者的合法利益.本文以LTE移动分组数据网络为例,介绍了移动分组数据业务计费检测技术,对移动分组数据业务计费检测中发现的问题进行研究分析.

Telecom network is still in the process of continuous development and evolution, which is par-ticularly prominent in LTE, IMS and Public WLAN areas. This article introduced basic information about these three networks, proposed two general methods for charging test by analyzing the network structure and charging principle. In addition, this article made a forward-looking thinking about billing and charging test in the new patterns of telecom services.

In this paper a method of time interval measurement based on gate delay is introduced. The method of time interval measurement and the structure and property of chip related to the design are presented, then the hardware and software design idea of the time interval measurement system are proposed, at last the uncertainty analysis of the whole system is made.

The communication quality plays an important role in the development and operation of mobile networks,so it's very necessary to test and evaluate the communication quality.Based on users'quality of experience,a new test and evaluation system with uniform test indicator system,uniform test method and uniform evaluation method as its main body,is given in the paper.The system can be applied to various mobile networks and provide reasonable evaluation results to telecommunications authorities,subscribers and operators.

General Packet Radio Service(GPRS) network is a mature radio data communication network,However,GPRS billing veracity is becoming as focus of telecommunication complaints at present.Through the study of the principles,process,triggers and contents of billing in GPRS network,the author comes up with three methods for testing the usage-based billing systems in GPRS network,and briefly analyses the advantages and disadvantages of these three methods.
