Description

实现网络电话的方法及网络电话设备 Way to network telephony and Internet telephony equipment

技术领域 FIELD

本发明涉及一种涉及基于计算机网络路由检测与旁路技术的宽带电话通信技术,尤其是涉及一种实现网络电话的方法及网络电话设备。 The present invention relates to a relates to a broadband computer network-based telephone communication technology and the bypass route detection technique, particularly to a method and implement VoIP telephone network equipment. 背景技术 Background technique

目前,宽带接入是现代通信的发展趋势,大量的个人家庭和公司都实 Currently, broadband access is the development trend of modern communication, a large number of individual households and firms are real

施了宽带接入(包括xDSL, Cable Modern, FTTB + LAN等等)。 Shi broadband access (including xDSL, Cable Modern, FTTB + LAN, etc.). 对个人用户而言,越来越多的用户采用了不限时专线接入方式;对公司用户而言, 绝大多数公司内已经实现LAN端口到座位;这些接入的网络相对于传统的话音专用电路具备更加富裕的带宽和传输能力。 Of individual users, more and more users using the line access mode when not; corporate users, most companies have implemented the LAN port to a seat; the access network with respect to the traditional voice dedicated circuit includes a richer bandwidth and transmission capacity.

IP电话(IP Phone)是建立在TCP/IP网络上的一种新兴语音通信技术,是丰富计算机网应用的一个重要方面。 IP telephony (IP Phone) is based on TCP / IP network, a new voice communication technology is an important aspect of rich computer network applications. 现有的IP电话应用集中在两个方面: Existing IP telephony applications focused on two aspects:

一是通过个人计算机上的语音通信软件进行计算机之间的话音、图像通信。 One for voice, image communication between computers via the voice communication software on a personal computer. 但这神通信方式的实施依赖于几个必要条件,包括双方计算机都已经接入计算机网络,都已开机,都运行了相互匹配的话音通信软件,双方计算机都安装了话筒和音箱,彼此知道对方的IP地址等等,这诸多环节阻碍了通过计算机的通话方式的进行; But the implementation of God's communication relies on several necessary conditions, including both the computers have access to a computer network, have been turned on, run a match with each other voice communication software, both sides are equipped with a microphone and computer speakers, know each other the IP address, etc., which hinders many aspects of the computer by way of a call;

另一种是PSTN普通电话终端通过拨叫IP电话网关进行相互拔叫。 The other is the ordinary PSTN telephone terminal dials each other by dialing IP telephony gateway. 这种方式主要在局端采用了IP相关技术,但用户仍然通过普通电话线接入,必须获得电信局分配的电话号码,由接入服务器解析拨叫的号码并完成电话接入,这种通信方式与用户安装的宽带接入网络并没有直接关系,不能利用宽带接入带来的灵活以及大带宽的优点。 This approach is mainly in the central office uses the IP related technology, users can still access over ordinary telephone lines, the phone number must be assigned to the bureau, the access server parses the dialed telephone number and complete access to, such communication with the user to install the broadband access network and not directly related to, and can not use a flexible high-bandwidth broadband access brings advantages.

此外,虽然市面上也开发出一些采用宽带接口的多媒体电话终端,但其需要独占的IP地址和物理网络接口而且往往需要专门的接续服务器,对个人用户来说占用了珍贵的公网IP地址资源,无法实现IP地址的共享, In addition, although the market has also developed a number of interfaces using broadband multimedia telephone terminal, but it needs exclusive IP address and physical network interface connection and often require specialized servers for individual users, taking up valuable public IP address resources , can not be shared IP address,

使其应用并不实际;对企业用户来说,必须为电话分配专门的LAN端口, 增大了设备投入开销。 Its application is not practical; for enterprise users, you must assign a dedicated LAN port for the phone, increasing the cost of equipment investment.

考虑基于计算机网络的电话通信实质:一,IP网络本身具有寻址能力; 二,在空闲状态,话音通信终端(或程序)只是申请并监听一个或某几个固定的公共端口,当需要通信时由该端口发起或接收呼叫请求,并根据通信双方的协商协议动态建立基于新端口的TCP或UDP通信连接;当通信结束,释放通信过程申请的通信端口,回到初始状态。 Consider computer network-based telephone communication essence: a, the IP network itself addressability; Second, in the idle state, voice communication terminal (or program) and apply only listen to one or several fixed common port, communication is required when from this port to initiate or receive a call request, and in accordance with a dynamic negotiation protocol communication parties establish a new TCP connection or UDP port based communication; when the communication ends, the process of applying the release of a communications port, back to the initial state. 因此,为实现基于IP 网的个人通信而完全占用一个完整的IP地址和所有端口非常浪费,带来的使用成本也很高。 Therefore, in order to achieve personal communication IP network-based and fully occupied an entire IP address and port all very wasteful, bringing the cost is also high.

4、 计算机对该设备进行设置:连接到固侧胺口4的计算机通过系统预设的默认端口访问网络处理器1;网络处理器1分析由计算机发起请求的数据包的目的地址,发现是设置端口,因此通过设置端口对计算机进行响应; 因为网络处理器1与电话处理器2通过内部通道进行连接,所以计算机也可以通过网络处理器1完成对电话处理器2的设置工作。 4, the computer device is provided: an amine attached to a solid side port of the computer 4 through the system preset default port for accessing a network processor; network processor 1 analyzes the destination address of the packet is initiating a request by the computer, is provided found port, thus responds to the computer through a port provided; the network processor 1 and the processor 2 are connected through a telephone internal passage, the computer may be provided to complete the work of the processor 2 through the telephone network processor 1.

为了最大限度节省个人用户的投资,可以把宽带接入模块(譬如ADSL, 终端、Cable Modern)集成在该系统中,可以由PC通过网络处理器1的默认端口对接入模块进行必要设置,还可以通过PC上安装辅助程序实现号码簿管理、网络电话机辅助拨号等功能。 In order to maximize savings in investment individual users can access the broadband module (such as ADSL, terminal, Cable Modern) integrated in the system, you may need to be set by the access module by the network processor PC default port 1, further You can install an auxiliary program to achieve Directory management through the PC, network assisted telephone dial and other functions.

如图3所示,对家庭多计算机小型网络用户,面临的环境是有一个WAN 地址和接口,但LAN端有多台计算机终端,这些终端分布在2~3个互通的 3, the plurality of home computer users small network, facing a WAN environment addresses and interfaces, but more than one LAN side computer terminals such distributed interworking 2-3

房间内,里面的人常用一个网络电话终端与外界进行电话联络(e^5^够), Room, the people inside a conventional VoIP terminal Tel (e ^ 5 ^ enough) with the outside world,

尽量用最少设备与投资完成上述所有功能仍然是追求的目标。 Try to complete all of the above functions are still pursuing the goal with minimal equipment and investment.

此时,网络电话仍然分享驻留在网络处理器1上的公网IP地址,但LAN端口则由一个有线或无线LAN交换机8(或者集线器)代替。 In this case, Internet telephony still resides in the network share on the public network processor 1 IP address, but the port by a wired LAN or wireless LAN switch 8 (or hub) instead. 此时,不看电话应用部分,则系统变成一个多计算机通过局域网和路由器与公网连接的结构,所以网络处理器1需要完成路由器的功能。 At this time, do not see a telephone application part, the structure of the system becomes more than one computer through a local network and the router connected to the public, the network processor requires a complete function of the router. 公网网络电话仍然通过拨叫该网络的公网地址可以拨叫到网络电话上;局域网内的计算机则通过网络处理器l (可由专用路由器处理器实现)代理上公网,内部为各个计算机分配不同的局域网地址,计算机之间通过LAN交换机8(或集线器)相连。 Public network by dialing the telephone call can still be a public network address of the telephone network to the network; the computers on the LAN (processor implemented by dedicated routers) via the proxy network processor l public network, each computer is assigned an internal different LAN addresses, between computer via LAN switch 8 (or hub).

各模块上IP分配:电话处理器2与网络处理器1共享WAN侧分配的IP地址,因此WAN上电话用户可以通过直接呼叫该公网IP拨打该网络电话;LAN交换机8(或集线器)所接内部计算机则根据内部路由器设置分配为内网IP地址。 Each module assigned IP: Telephone network processor 1 and processor 2 share the WAN side IP address allocated, WAN so the user can directly call the telephone of the public network to call the IP telephone network; the LAN switch 8 (or hub) is connected the internal computer is arranged inside the router IP address assigned to the network.

信息处理过程: Information processing:

1、 WAN网络电话拨打本机和本机拨打WAN网络电话,处理过程与前述方法相同。 . 1, WAN and the Internet phone calls native native WAN network telephone call, the process was the same as the aforementioned method.

2、 内部计算机对WAN的访问则因为PC不再共享WAN侧IP地址,由网络处理器1完成路由到公网的访问过程,此过程与普通内网用户通过路由器路由到公网一致。 2, the internal computer access to the WAN is no longer shared PC because WAN side IP address, access by the network processor performs a routing process to the public network, this process is common to the users within the network through a router consistent with the public network routing.

此实现模式因为电话与WAN端口共享工P地址,所以只能有一个接听终端。 This implementation mode is because the telephone and the WAN port address shared work P, so there is only a receive terminal. 对家庭型用户而言是足够了。 For home-based users is enough.

为了节省投资,对个人用户而言,仍然可以如前一方案集成专用宽带接入设备。 In order to save investment for individual users, it can still be as in the previous solution integrates a dedicated broadband access equipment.
