不正常计费话单的分析处理

随着广大用户消费意识、自我保护意识的增强,电话收费问题特别是长途话费问题（如长／短话单问题）,已成为用户投诉的热点。计费话单主要有以下几个参数：主叫号码、被叫号码、通话时长（以及摘机时间、挂机时间、出入中继群号）。话单分为两大类：正常话单、不正常或错...     

交换机异常话单的分析处理

随着社会的进步和消费透明度的提高，人们对电信计费的准确性要求也越来越高，如何尽可能地提高运行维护质量，提高计费准确性将是一项非常重要的工作。这里根据自己的工作体会，以华为公司的C＆C０８交换机为例对异常话单现象进行了归纳分析，并列举了一些处理实例。１交叉话单交叉话单是指同一主叫用户所产生的两张话单，其被叫号码可能相同，也可能不同，但在时间上有重叠。如：主叫号码被叫号码起始时间通话时长７２１０８０８７２１１２４００８誜０１誜０６８０s７２１０８０８７２１５１０００８誜０２誜１６９０s产生上述交叉话单…     

重复话单剔除技术剖析

1引言 各个话单采集点在某些异常情况下可能产生重复话单,如果不及时将重复话单剔除,将导致用户的费用出错,引起用户的投诉,造成客源流失。因此,在计费结算系统中,必须将重复话单剔除。剔除重复话单(以下简称“剔重”)的基本思路就是：记录一段时间内所有话单中具有惟一性标识作用的主叫号码、被叫号码、通话起始时间和话单类型等关键字段值,在处理新话单时将新话单的关键字段值与已经记录的话单进行比较,     

长途非正常话单的分析与解决

本文记叙了Ｓ１２４０交换机ＥＣ７４版本的两种长途话单异常情况及处理过程：一种情况是由于不能用人机命令对ＤＥＳＴＳＩＧ分源引起的收不到主叫号码时仍继续接续,造成长途话单中主叫号码不全;一种情况是当主叫是ＩＳＤＮ用户时,有时收到主叫号码的情况仍出现计费话单中无主叫。通过对处理过程的描述,简要介绍了一种处理异常长途话单的思路。     

基于信令方式的虚假移动主叫号码实时监控方案

主叫号码显示,即来电显示是通信网络的一项基本功能,它的广泛应用为广大用户带来了极大的便利。近期社会上出现了利用虚假移动主叫号码进行通话的行为,甚至被一些不法分子用于实施诈骗、电话骚扰、恶意窃取用户信息等非法活动。这些虚假主叫通话行为严重侵犯了合法用户的正当利益,不仅引发客户投诉,更造成用户对移动通信业的信任危机,因此通信网络迫切需要有效的技术手段实现对虚假移动主叫号码的监控和拦截,遏制虚假呼叫的蔓延。     

多路电话自动计费系统的设计

目前，许多中小型电信营业厅和宾馆、饭店、车站、码头等邮电代办点都需要一种控制多路（4～8路）电话的即时自动计费设备。为满足社会的需求，我们研制了多路电话自动计费系统。该系统具有以下功能：（1）能同时监视、控制多路电话；（2）能正确接收用户拨号，并自动分析号码，确定费率；（3）能自动判别通话状态，确定通话时间，并准确计费；（4）能自动记录每次成功通话的各项数据；（5）能实时或定期打印话单；（6）能自动识别和正确接收脉冲和双音多频信号；（7）能同时显示所有话路的状态、呼叫号码、通话时间、话费等信息；（8）能方…     

EWSD交换机如何实现对非法呼叫的限制

针对网上大量的无效话单,我们可以通过对直拨用户交换机（DID）发起的呼叫进行主叫号码鉴别,对携带的主叫号码是非法号码或无效号码的呼叫予以拒绝,以保护企业利益。     

手机单向收费:千呼万唤要出来

3月 11日 ,信息产业部服务监督处处长黄澄清指出 ,信息产业部对消费者呼声很高的“手机单向收费”正在制定有关管理办法 ,单向收费的提议有可能得到实现。1　我国移动电话缘何采取双向收费　方式　　我国是从 1987年开办移动电话业务的。据专家介绍 ,我国移动电话用户主叫与被叫间通话为什么要采取双向收费的方式 ,主要基于以下几点 :一是参照了国际上一些国家的收费办法。目前许多国家移动电话用户主叫与被叫间通话 ,采取移动电话主叫单向收费方式 ,一些国家采取移动电话主叫、被叫双向收费方式。我国移动电话业务开办初期 ,引进的是美国的…     

OS2的用途

ＯＳ２是阿尔卡特移动通信系统提供的一项用户跟踪功能。操作人员在ＨＬＲ终端上为需要的用户增加这项功能后，该用户无论做主叫还是被叫，当通话结束，它所在地的交换机就会出一个系统报告，详细记录该次通话的各项信息。ＯＳ２最初用于向执法机关及时提供用户的通话对象，但由于它的系统报告迅捷、详细、完整、明晰，在进行故障分析时，有着意想不到的功效。ＯＳ２的系统报告如下：整个报告分为两部分。前半部分为这次通话的有关信息，有通话时间、主被叫号码、占用的出入中继、手机所在的基站等；后半部分为主叫方（ＡＳＩＤＥ）、被叫方…     

计弗问题面面观

处在发展建设阶段的电信企业 ,因企业检修线路、设备的搬迁、工程割接、网络和软件的升级以及电信资费的频繁调整 ,都会在一定程度上影响计费的准确性。在日常遇到的计费问题中 ,有些与计费系统和程控交换机系统相关 ,还有一些是因用户不熟悉资费政策以及其他的原因造成的。１用户的误解（１）用户反映拨打１６３、１６９上网出现重复话单 ,即在相同的时间段同样的主叫号码出现两张话单。这是一个ＩＳＤＮ用户 ,使用了双信道上网 ,因此计两张话单是正确的。（２）用户改号后 ,查看详细话单时发现有原号码的费用。为避免话费收入的流失 ,计费…     

A New Electronic Telephone Accounting System for Local Telephone Calls

Telephone switching systems provide facilities to measure subscriber usage for billing purposes. As new telephone services are offered, additional equipment is often required to appropriately measure this usage. Rate plans are being considered by telephone companies to more appropriately reflect service rendered on local telephone calls and additional equipment is required. This paper describes an electronic local message accounting system to measure local call usage which can be appliquéd to Panel, No. 1 crossbar, No. 5 crossbar, and Step-by-Step switching entities. Magnetic tape records for each local call provide: directory number of the calling party, distance to the called party, duration, and time of call termination. This information allows subscriber billing based on many and varied criteria which are established by software at the revenue accounting office. The system is presently in widespread use. The first installation occurred in January 1972, and now almost 5 percent of all telephones in the United States are served by the system.     

追查恶意呼叫电话与主叫识别业务

介绍了程控电话交换机追查恶意呼叫和主叫用户信息识别业务的各种识别方法,特别是详细介绍了利用话务台和话机上的“R”键转接的功能,以及利用能显示主叫信息的话机来显示主叫电话号码和追查恶意呼叫电话的方法。说明了利用能显示主叫信息的话机来显示主叫信息,是程控电话交换机的一种新业务。     

一种3G中基于三层数据库的呼叫建立机制研究

基于3G网络三层数据库结构中GLR (Gateway Location Register)服务区远大于VLR (Visitor Location Register)服务区的情况,考虑被呼业务本地化(即本地移动用户呼叫本地移动用户的比例占总呼叫数的比例大),通过在GLR中设置缓存的方法,给出了一种新的呼叫建立机制。建立分析模型得到新机制的总代价函数和总时间延迟函数,并同基本呼叫建立机制以及2G网络基于VLR缓存的呼叫建立机制进行了对比分析,验证了新呼叫建立机制的优越性。     

A Provable Billing Protocol on the Current UMTS

This paper proposes a simple method that equips UMTS-based telecom companies with a mechanism to prove the records on mobile users’ phone bills. In the history of mobile phone communication, we have seen countless unsettled disputes where the mobile user disagrees with the telecom company either on the calling time or on the duration, or even on whether or not a call was actually made. In this paper, a provable billing protocol will be presented that can effectively solve disagreements between the two parties. Equipped with a non-repudiation function, the proposed protocol enables the service provider to hold on to the solid proofs as to exactly when and to which number a mobile phone user made a call so that the mobile user cannot deny; at the same time, the mobile user also gets to have his/her own share of proofs as to when and how the mobile services were accessed, so that the bill can be double checked to make sure nothing goes wrong. And, to make it even better, this new protocol is perfectly compatible with the standard UMTS protocol and is therefore readily applicable to the current mobile phone communication environments.     

The allocation of value for jointly provided services

Caller I.D. service, whereby the telephone number of the calling party is visually displayed to the called party during ringing, is now available in some areas of the U.S., but it is restricted to calls within a local calling area, and for which the calling and called party are customers of the same local telephone company. If Caller I.D. service is extended nationwide, identification of a long-distance call will, in a typical case, require the participation of three companies: the local exchange carrier originating the call, the long-distance carrier, and the local exchange carrier terminating the call. How shall the revenues from the service be divided among the participating firms? We apply cooperative game theory to address this question.     

基于nRF401的无线呼叫服务系统设计

无线呼叫服务系统为点对多点通信,存在信道冲突问题.文中采用呼号广播的方法分配信道,即以中央控制器广播各呼叫器的编码呼号,统一了时分复用的计时基准点和计时时钟,实现各受服务时间片的准确分配.系统硬件设计本着低成本原则,呼叫器以AT89C2051和nRF401为核心,并做到零功耗空闲,中央控制器结构与呼叫器基本相同,以七彩LED(发光二极管)和数码管进行呼叫显示,并通过串行口与PC机相连接.基于VC 设计服务系统软件安装于PC机上,以激活的消息框提醒需要服务客人的编号.     

语音呼叫路由汇聚的方法设计与实现

为降低语音呼叫的数据采集成本,研究了呼叫路由汇聚方法,对于经过网关的每一通呼叫,在对应被叫号码前添加特殊数字前缀,作为路由汇聚需求的唯一标识,实现信令与媒体的数据路由指向特定汇聚网元。实践表明,数据路由经汇聚后,呼叫可继续接续,不影响用户感知,采集成本约为传统方法的1‰。     

Adaptive routing considering the number of available wavelengths in WDM networks

In most existing studies of wavelength-division multiplexing networks, the problems of routing and wavelength assignment are generally treated separately, since it is NP-complete to produce the optimal solutions for the two problems at the same time. The four presented adaptive routing algorithms, however, consider the availability of wavelengths during the routing process. Our algorithms favor paths with the near-maximum number of available wavelengths between two nodes, resulting in improved load balancing. Simulations show that our algorithms reduce call blocking by nearly half when compared with the least-loaded and the k-fixed routing algorithms in some small networks using the first-fit wavelength assignment policy. In addition, simulation and analysis show that the path length of our algorithms is almost the same as those of the other algorithms.     

Personal communications-a viewpoint

A personal view of an extended concept of personal communications is discussed. The relationship between low-power digital cordless technology and some alternatives (analog cordless, digital mobile radio, and cellular mobile radio) is examined. Personal communication network (PCN) power requirements, circuit quality, level of network integration, and access to network intelligence (e.g. call forwarding, call transfer, and personal number calling) are emphasized     

基于AT89C52单片机的病房呼叫系统设计

病房呼叫系统是快速处理病人请求的重要装置,传统的病房呼叫系统缺乏根据病情对病房优先选择的能力,功能单一.本文基于单片机AT89C52设计具有优先选择功能的病房呼叫系统,采用独立按键输入病房号,利用单片机编程处理数据,当有多间病房同时呼叫时对应指示灯同时亮,但在数码管上只显示优先级别高的病房号,并伴有报警提示铃响.
