  • End-to-end call implementation method end-to-end call terminal and system
  • the present invention relates to the field of communications and the Internet, and in particular, to an implementation method of an end-to-end call, an end-to-end calling terminal, and a system.
  • the Internet was invented in the 1970s. It is difficult to predict that there will be a large number of mobile terminals and multiple township terminals in the world today. Therefore, the Internet protocol stack at that time was mainly designed for terminals connected in a "fixed" manner.
  • the transmitted address is the received address, and the path is reversible, so the IP address with dual attributes of identity and location can work very well. There is no conflict between the identity attribute of the IP address and the location attribute.
  • the IP address also represents the identity and location that exactly met the network needs of the time. From the perspective of the network environment at the time, this design scheme is simple and effective, simplifying the hierarchy of the protocol stack.
  • the identity attribute of an IP address requires that any two IP addresses be equal.
  • the location attribute of the IP address requires that the IP address be assigned based on the network topology (not the organization), and the IP addresses in the same subnet should be in a continuous In the IP address block, the IP address prefix in the network topology can be aggregated, thereby reducing the routing table entries of the router device and ensuring the scalability of the routing system.
  • the inherent contradiction between the dual attributes of IP addresses will lead to the following main problems:
  • Routing scalability issues There is a basic assumption about the scalability of Internet routing systems:
  • the address is assigned according to the topology, or the topology is deployed according to the address, and the two must choose one.
  • the identity attribute of an IP address requires that the IP address be assigned based on the organization to which the terminal belongs (rather than the network topology), and this allocation must be stable and cannot be changed frequently; the location attribute of the IP address requires the IP address to be based on the network.
  • the topology is allocated to ensure the scalability of the routing system. In this way, the two attributes of the IP address create conflicts, which eventually leads to the scalability problem of the Internet routing system.
  • the identity attribute of the IP address requires that the IP address should not change as the location of the terminal changes. This ensures that the communication bound to the identity is not interrupted, and that the terminal can still use its identity after the terminal is moved.
  • the communication link is established; the location attribute of the IP address requires the IP address to change as the terminal location changes, so that the IP address can be aggregated in the new network topology, otherwise the network must reserve a separate route for the mobile terminal.
  • Information which causes a sharp increase in routing table entries.
  • a number of township issues A plurality of townships usually refer to terminals or networks that access the Internet through a network of multiple ISPs (Internet Service Providers).
  • ISPs Internet Service Providers
  • the advantages of multiple township technologies include increased network reliability, support for traffic load balancing across multiple ISPs, and increased overall available bandwidth.
  • the identity attribute of an IP address requires that a plurality of home terminals always display the same identity to other terminals, regardless of whether the multiple township terminals access the Internet through several ISPs; and the location attribute of the IP address requires that multiple township terminals are different.
  • the ISP network uses different IP addresses to communicate, so that the IP address of the terminal can be aggregated in the topology of the ISP network.
  • IP address includes both the identity information and the location information of the terminal
  • the communication peer and the malicious eavesdropper can simultaneously obtain the identity information and the topology location information of the terminal according to the IP address of the terminal.
  • the dual attribute problem of IP address is one of the fundamental reasons that plague the Internet to continue to develop. Separating the identity attribute and location attribute of an IP address is a good way to solve the problems faced by the Internet.
  • the new network will be designed based on this idea, and propose a network structure of separate mapping of identity information and location information to solve some serious drawbacks of the existing Internet.
  • HIP Home Identity Protocol
  • Some schemes classify IP addresses, some IPs.
  • the identity part of the IP is used as the location identifier, such as LISP (Locator/ID Separation Protocol);
  • LISP Licator/ID Separation Protocol
  • the patent CN200610001825 of the Northern Jiaotong University Zhang Hongke also proposes a solution to use the IP address as the location identifier of the host, introduced End host ID is resolved as an identity
  • the problem of separation of identity and location The above proposals and solutions all propose the implementation of identity and location separation solutions under the existing network architecture from some parts of the problem. Location and identity separation is the core technology of future data communication networks, especially mobile data communication networks.
  • End-to-end call technology In the implementation technology of VOIP (voice over Internet Protocol), there are two ways, one is to capture the client-server (client-server) mode technology, that is, the VOIP server exists in the network. Such as media gateway controller, gateway gatekeeper, proxy server, etc. Call routing, call signaling, media control, etc. H.323, SIP (Session Initiation Protocol), softswitch, etc. are all VOIP technologies that capture the Client-Server model. Operators have a wide range of applications because operators can control the call and signaling processes of VOIP and charge for services.

  • H.323, SIP (Session Initiation Protocol), softswitch, etc. are all VOIP technologies that capture the Client-Server model. Operators have a wide range of applications because operators can control the call and signaling processes of VOIP and charge for services.
  • Another implementation method of VOIP captures the end-to-end call mode, that is, the server in the network that is not in the central or control position, and the terminal directly and the other terminal complete the entire process of calling and signaling.
  • This type of technology has Internet features, namely free and open.
  • Skype is a VOIP technology for end-to-end calls. Its emergence has brought a strong shock wave to the traditional telecom industry. Up to now, Skype has registered 250 million global users, and the number of members increased by 155,000 per day. As of March 14, 2005, Skype's global call volume has reached 6 billion minutes. Skype is still rapidly infiltrating into various countries. The latest statistics show that: The number of minutes of calls using Skype technology has accounted for 46.2% of the US VoIP minutes.

端到端呼叫的实现方法、 端到端呼叫终端及系统
技术领域 本发明涉及通信、 互联网领域, 尤其涉及一种端到端呼叫的实现方法、 端到端呼叫终端及系统。
背景技术 身份和位置分离技术 关于下一代信息网络架构的研究是当前最热门的课题之一。 目前大多数 研究接受的观点是: 未来网络将以互联网为统一承载网络。 互联网从其诞生 以来一直保持高速发展, 已成为当前最成功、 最具生命力的通信网络, 其灵 活可扩展性、 高效的分组交换、 终端强大的功能等特点非常符合新一代网络 的设计需要, 互联网将是新一代网络设计的主要参考蓝本。 然而, 互联网的结构还远远没有达到最优, 存在很多重大的设计问题, 其中比较典型的是 IP地址的双重属性的问题, 即 IP地址既代表用户身份, 又代表用户所处的网络拓朴, 即 IP地址的双重属性。 互联网发明于二十世纪 七十年代, 人们难以预计今天世界上将存在大量的移动终端和多家乡终端, 因此当时的互联网协议栈主要是针对以 "固定"方式连接的终端而设计。 在当 时的网络环境下, 由于终端基本上不会从一个位置移动到其它位置, 发送的 地址就是接收的地址,路径是可逆的, 所以具有身份和位置双重属性的 IP地 址能够非常好的工作, IP 地址的身份属性与位置属性之间没有产生任何冲 突。 IP地址同时代表身份和位置恰恰满足了当时的网络需求。 从当时的网络 环境来看, 这种设计方案简单有效, 简化了协议栈的层次结构。 但毋庸置疑 的是, IP地址的身份属性与位置属性之间存在着内部矛盾。 IP地址的身份 属性要求任意两个 IP地址都是平等的, 虽然 IP地址可以按照组织机构进行 分配, 但是连续编码的 IP地址之间没有必然的关系, 或者至少在拓朴位置 上没有必然的关系; IP地址的位置属性则要求 IP地址基于网络拓朴(而不 是组织机构)进行分配, 处于同一个子网内的 IP地址都应该处于一个连续 的 IP地址块中, 这样才可以使网络拓朴中的 IP地址前缀聚合, 从而减少路 由器设备的路由表的条目, 保证路由系统的可扩展性。 总的来说, IP地址双重属性的内在矛盾将导致如下主要问题:
1. 路由可扩展问题。 关于互联网路由系统的可扩展性存在一个基本的假 定:
"地址按照拓朴进行分配,或者拓朴按照地址进行部署,二者必选其一"。 IP地址的身份属性要求 IP地址基于终端所属的组织机构(而不是网络拓朴) 进行分配, 而且这种分配要保持一定的稳定性, 不能经常改变; 而 IP地址 的位置属性要求 IP地址基于网络拓朴进行分配, 以便保证路由系统的可扩 展性。 这样, IP地址的两种属性就产生了冲突, 最终引发了互联网路由系统 的可扩展问题。
2. 移动性问题。 IP地址的身份属性要求 IP地址不应该随着终端位置的 改变而变化, 这样才能够保证绑定在身份上的通信不中断, 也能够保证终端 在移动后, 其它终端仍能够使用它的身份与之建立通信联系; 而 IP地址的 位置属性则要求 IP地址随着终端位置的改变而改变,以便 IP地址能够在新 的网络拓朴中聚合, 否则网络就必须为移动后的终端保留单独的路由信息, 从而造成路由表条目的急剧增长。
3. 多家乡问题。 多家乡通常指终端或网络同时通过多个 ISP ( Internet Service Provider, 因特网服务提供商) 的网络接入到互联网。 多家乡技术的 优点包括增加网络的可靠性、 支持多个 ISP之间的流量负载均衡和提高总体 可用带宽等。 但是, IP地址双重属性的内在矛盾使得多家乡技术难以实现。 IP地址的身份属性要求一个多家乡终端始终对其它终端展现不变的身份,无 论该多家乡终端是通过几个 ISP接入到互联网; 而 IP地址的位置属性则要 求一个多家乡终端在不同的 ISP 网络中使用不同的 IP地址通信, 这样才能 保证终端的 IP地址能够在 ISP 网络的拓朴中聚合。
4. 安全和位置隐私问题。 由于 IP地址同时包含终端的身份信息和位置 信息, 所以通信对端和恶意窃听者都可以根据一个终端的 IP地址同时获得 该终端的身份信息和拓朴位置信息。 总的来说, 自从传统互联网的体系结构建立以来, 互联网的技术环境和 用户群体都已经发生了翻天覆地的变化, 互联网需要随之进行革新。 IP地址 的双重属性问题是困扰互联网继续发展的根本原因之一, 将 IP地址的身份 属性和位置属性进行分离, 是解决互联网所面临问题的一个很好的思路。 新 网络将基于这种思路进行设计, 提出一种身份信息与位置信息分离映射的网 络结构, 以解决现有互联网存在的一些严重弊端。 为了解决身份和位置的问题, 业界进行了大量的研究和探索, 所有身份 与位置分离方案的基本思想都是将原本绑定在 IP地址上的身份与位置双重 属性分离。其中,有些方案釆用应用层的 URL ( Uniform Resource Locator, 统 一资源定位符, URL是用于完整地描述 Internet上网页和其他资源的地址的 一种标识方法) 或 FQDN ( Fully Qualified Domain Name, 合格域名 ) 作为 终端的身份标识, 如 IPNL ( IP Next Layer, IP下一层, 属于 NAT扩展架构 的方式) 、 TRIAD ( A Scalable Deployable NAT-based Internet Architecture, 一种可扩展易部署的基于 NAT的网络架构) 等; 有些方案引入了新的名字 空间作为身份标识, 如 HIP ( Host Identity Protocol , 主机标识协议)在以 IP 地址为标识网络层上增加主机标识; 有些方案将 IP地址进行分类, 部分 IP 作为身份标识, 部分 IP 作为位置标识, 如 LISP ( Locator/ID Separation Protocol , 位置身份分离协议) 等; 北方交通大学张宏科的专利 CN200610001825也提出一种解决方案, 使用 IP地址作为主机的位置标识, 引入端主机标识作为身份标识解决身份和位置分离的问题。 上述的提案和方案都从问题的一些局部提出在现有的网络架构下实现身 份与位置分离解决方案, 位置与身份分离是未来数据通信网络的核心技术, 特别是移动数据通信网络。
端到端呼叫技术 在 VOIP ( Voice over Internet Protocol , 网络电话) 的实现技术中, 有两 种方式, 一种是釆取 Client-Server (客户机-服务器)模式的技术, 即网络 中存在 VOIP服务器如媒体网关控制器、 网关网守、 代理服务器等, 负责处 理呼叫选路、呼叫信令、媒体控制等, H.323、 SIP ( Session Initiation Protocol, 会话初始协议) 、 软交换等都是釆取 Client-Server模式的 VOIP技术, 这类 技术在传统的电信运营商有广泛的应用, 因为运营商能够控制 VOIP的呼叫 和信令流程, 从而对业务收费。 另一种 VOIP的实现技术釆取端到端呼叫的方式, 即网络中并没有处于 中心或控制地位的服务器, 由终端直接和对方终端完成呼叫和信令的整个流 程。 这类技术具备互联网特性, 即免费和开放。 Skype 就是釆取端到端呼叫 的 VOIP技术, 它的出现给传统电信业带来一股强烈的冲击波, 截至目前, Skype全球注册用户数已达 2.5亿, 每天增加的会员有 15.5万人, 而到 2005 年 3月 14 日为止, Skype在全球的通话量累计已经达到 60亿分钟。 Skype 仍在迅速向各个国家渗透, 最新的统计表明: 使用 Skype技术呼叫的分钟数 已经占到美国 VoIP分钟数的 46.2%,这部分用户基本是"免费,,享用电话业务 的。 现有互联网的端到端呼叫是工作在应用层, 通过用户名和密码标识一个 用户。 但互联网是根据 IP地址寻址, 无法根据用户名和密码寻址, 所以网络 中还需要一个处于中心位置的注册服务器, 建立应用层的用户名和网络层的 IP地址之间的映射关系, 并把这个映射关系返回给用户。 注册服务器还需要 检验并保证用户名的全球惟一性。 目前已经揭示的各种身份位置分离架构网络都没有对端到端呼叫提出具 体的应用方案, 当然更没有解决以上现有端到端呼叫的缺陷。
