The Internet switching service method for providing an Internet switching service to a subscriber connected to the Internet (214) to make an Internet telephone call by using an ID of a receiver are achieved by inputting the ID of a receiver who the subscriber wishes to communicate with, searching a data base (202) where a plurality of IDs and communications address data of the IDs are previously stored, for communications address data corresponding to the IDs, sending the searched communications address data to the subscriber, and the subscriber performing a telephone call, a fascimile transmission or sending a post by using the searched communications address data.

对与因特网(214)连接的用户提供因特网交换业务以利用接收方ID进行因特网电话呼叫的因特网交换业务方法，通过下列步骤实现：输入该用户想与之通信的接收方ID，对先前存储有多个ID和这些ID的通信地址数据的数据库(202)搜索与该ID对应的通信地址数据，将搜索到的通信地址数据送给用户，以及该用户通过用搜索到的通信地址数据进行电话呼叫、传真发送或发送邮件。

Asok Chatterjee was one of the founders of 3GPP - the organization that came into existence 7 years back and is still busy standardizing the evolution of W-CDMA-based third generation mobile wireless systems.

阿索克 查特杰博士在印度和加拿大完成了他的学业并从事电信业超过30年。他一开始是从事研发工作，之后他开始了本地与远程通信，卫星通信，无线通信包括蜂窝移动通信的事业当中。

With the transition to 3G of the cellular mobile communication, the trunked system is converting from analog technology to digital technology.

This paper is derived from the experiment of the Reconnaissance and Jamming for Ultrashort Frequency Hopping Communication.

本课题来源于《超短波跳频通信的侦察与干扰实验》，该实验的目的是为了以实验的形式展示跳频通信的工作原理，跳频通信的侦察与干扰方法以及跳频通信各种干扰方法的性能比较。

The service provider performs the following steps: receiving a request from a customer to establish communication with another customer; confirming the identity of each customer; transmitting to each customer executable code enabling encrypted communication therewith; obtaining from each customer information regarding the customer's computing environment; preparing a set of applications for use by each customer, in accordance with the customer information and the customer's request; transmitting the set of applications as executable code to each customer; establishing a communication path to each customer; and specifying the communication path to the customers, thereby permitting the customers to communicate over the path using those applications.

服务提供商执行以下步骤：接收从一个客户发出的与另一个客户建立通信的请求；确认各个客户的身份；向各个客户发送能实现加密通信的可执行代码；从各个客户处获得关于客户计算环境的信息；按照客户信息和客户请求，准备一组应用程序供各客户使用；把这组应用程序作为可执行代码发送给各客户；建立与各客户的通信通道；向客户说明通信通道，从而允许客户使用那些应用程序在该通道上进行通信。

One of the incentives of anonymous communication is to hide either the identity of communicators or the communication relationship within the traffic flow, therefore materilising the users privacy and better protection for confidential communication.

匿名通信的一个重要目的就是隐藏通信双方的身份或通信关系，从而实现对网络用户的个人通信隐私及对涉密通信的更好的保护。
