电信运营商的电话号码查询业务发展策略

国内的电话号码查询业务就是大家所熟悉的114业务,114查号台仅向用户提供免费（只收基本通话费）的基本查号业务,在国外,电话号码查询业务逐步演变成收费业务并出现了多种增值业务,一些国家的电诠管制机构将该业务市场放开,使得号码查询业务蓬勃发展,成为投资者和业务提供商追逐的热点。挖掘国外电信运营商的电话号码查询业务发展策略,对比我国的业务发展现状,将给我们以深刻的启示。     

新品发布

智能网络终端上海贝尔查询号181NT1 BL型是在NT1 原有型号基础上的升级换代,以KEYPAD（键盘操作）方式支持各种电信新业务。与现有的NT1 产品相比,NT1 BL的主要改进是来电显示方式的多样化和电话号码存储量的大幅度提高：不仅可通过自身的液晶屏显示来电号码,同时还支持带来电显示功能的话机和主叫号码显示器。电话号码存储能力由现有产品的8个提高到多达30个电话号码（接通和未接通皆可）。用户在查询号码时也可同时看到该电话拨入的时间。NT1 BL的液晶屏还提供号码查询和删除以及时间设置功能界面。边缘路由器Unisphere Ne…

我国114业务的未来管制思路分析

作为一种客户服务甚至是盈利的业务，世界上很多电信公司都为用户提供电话接人方式的号码查询业务，我国的电话号码查询业务一直以114作为接人号，因此人们常常把我国的电话号码查询业务称为114业务。随着我国通信业的引入竞争，电信改革给114业务的发展带来了许多前所未有的新问题。电信改革的目标是为用户带来服务更好、更经济实惠的电信业务，而114业务的发展却正在与这一目标背道而驰。114业务如何与电信改革同步发展、114的未来发展之路应该如何走等话题，成为业界关注的焦点。

号码可携带业务的实现与运用

随着我国经济的不断发展,用户对电信业务的种类要求越来越多,功能要求也越来越强,其中号码可携带业务是近年来发展起来的一项新业务,这项业务主要是企业、团体。商业机构或个人在迁移地址后仍使用原来的电话号码,避免再进行广告宣传等活动。香港从１９９５年就开始开展号码可携带业务,运用比较普遍。美国。日本、新西兰等发达国家也才刚刚起步。本文介绍号码可携带业务的概念和类型及国内、国外号码可携带业务的实现方法和运用。 一、号码可携带业务的概念 号码可携带（ＮＰ）业务又称为移机不改号业务,即一个用户拥有永久的电话号码…     

一种基于SHLR的虚拟号码业务的研究

针对高度重视个人隐私保护的电信固话用户,设计了一种基于智能网和SHLR的虚拟号码业务,简称飞号业务。飞号业务的主要特色是：是在客户不更换电话号码的情况下,为客户提供多个虚拟号码;客户使用“虚拟号码”既可接听来电,也可使用“虚拟号码”作为主叫显示号码拨出电话。每个“虚拟号码”都可以进行管理,包括开关机、播放个性化的回铃音等操作,使用“虚拟号码”实现将号码隐藏并进行来电筛选的功能。该业务将成为一种极具市场价值的增值业务。     

对我国实行“电话号码可携带”的综合思考

当 前,中国的电信市场正处于剧烈的变 革之中,3G 时代即将来临,全业务 运营商即将诞生,新《电信法》即将出台, 这些都将影响到整个市场的格局。而用户 对电信业务种类的需求也越来越多,更迫 使运营商们无不施展浑身解数打拼市场, 其中号码可携带(Number Portability,NP) 是近几年来比较热门的话题。号码可携带 业务也称为移机不改号业务,即用户拥有 永久的电话号码,称为可携带号码。当用 户移机后,仍可使用原来的电话号码。此 业务极大地方便了用户,避免了移机后必 须更换电话号码及相应带来的诸多麻烦。 号码可携带的业务…     

号码携带国际发展趋势

号码携带主要分为3类，分别是位置号码携带、业务提供者携带和业务携带。位置号码携带能让用户在更换物理位置的情况下保留原先的电话号码；业务提供者携带是用户更换运营商而保持电话号码不变；业务携带是用户在保持电话号码不变的同时，向不同服务提供商订购业务，业务携带还没有在任何一个同家实施，但是有些国家的未来发展规划中将此列在其中。     

p XCube云模型的任务划分技术

Query efficiency is bottleneck of XML data cube aggregate query. p XCube is a kind of XML data cube model based on path calculation. Join operations are avoided in this model, but the query efficiency of fact cell is become a new bottleneck. This paper focuses on parallel technology of cloud computing to improve query efficiency of p XCube. Mixed partitioning strategy for fact and dimensions is applied in p XCube cloud model, and the same partitioned vector is adopted. Query parallel algorithm of p XCube cloud model is presented as well. Experiments show that the query cost of p XCube cloud model decreases with the increasing number of parallel nodes gradually. The query cost of fact fragments of each node are close to or even lower than join operations of dimensions , and the Speedup is with better linear. So the model is well suited for decision supported query.

Number portability for telecommunication networks

Number portability is a telecommunication network function, which allows subscribers to switch services, service providers, or locations without changing their telephone numbers. Near-term number portability is typically implemented by existing telecommunication services such as remote call forwarding. Long-term number portability can be implemented under the advanced intelligent network (AIN) platform. This article focuses on the routing issues for number portability. We introduce the number portability issues and provide a tutorial on the AIN. We then show the AIN implementation for long-term number portability. Finally, a cache approach is proposed to speed up address transfer, which can effectively reduce the network overhead incurred by AIN query for number portability     

VoIP insecurity

As voice over Internet Protocol (VoIP) moves into the mainstream in the UK, and new IP-based services such as IIPTV become available, there is a serious need to secure these systems. With the public switched telephone network (PSTN), users at all levels have peace of mind that the lines are not only reliable and available, but highly secure. A proactive security strategy which addresses security at multiple levels and understands the unique nature of telecommunication networks is critical to enable organizations and service providers to maximize the true potential of VoIP technology, create cost savings and deliver highly available and reliable services to their customers and employees     

A trajectory-based selective broadcast query protocol for large-scale,high-density wireless sensor networks

We present a small-footprint search protocol designed to facilitate any-type queries for data content and services in large population, high-density wireless sensor networks. Our protocol, termed Trajectory-based Selective Broadcast Query (TSBQ), works in conjunction with time division multiple access- or schedule-based medium access control protocols to reduce per-query energy expenditure. We compare the performance of TSBQ to unicast- and local broadcast-based search algorithms and also determine a critical node density based on the energy expended by nodes to transmit and receive. Minimal energy expenditure is achieved by determining the optimal number of data/service replicates and the number of nodes designated to receive each query transmission. Numerical results indicate that TSBQ significantly reduces the total energy expenditure of a network as compared to unicast and local broadcast-based search protocols.     

Distributed GEP query optimization on grid service

In order to better solve the problem of distributed query optimization,a query optimization algorithm on gene expression programming(GEP)(QO-GEP)is presented.On the basis of QO-GEP,distributed GEP query optimization on grid service(DGEPQO-GS)is proposed which combines grid service.Simulated experiments show that with the increment of the number of query relation,query time which QO-GEP carries out query decreases apparently.Meanwhile,with the increase of the number of grid nodes,the average querying success rate of DGEPQO-GS increases significantly.

iSMS: an integration platform for short message service and IPnetworks

This article describes iSMS, a platform that integrates IP networks with the short message service in mobile telephone systems. iSMS provides a generic gateway for creating and hosting wireless data services for mobile stations. Our approach does not require any modification to the mobile telephone system architecture. The iSMS system can be quickly developed and operated by a third party or end user without involvement of mobile equipment manufacturers and telecom operators. Based on the iSMS platform, we illustrate services such as e-mail delivery/forwarding, Web access (e.g., stock and train schedule query) and handset music services. The iSMS platform and the services have been implemented for GSM networks. With iSMS, users are able to use standard GSM handsets to access wireless Internet services, while other approaches like the Wireless Application Protocol and SIM Toolkit services require function-enabled MSs
