Description

用于IP地址分配的方法和设备
技术领域
本发明的实施例涉及无线通信系统；更具体地说，本发明的实施例涉及IP(因特网协议)地址分配。
背景技术
移动微波接入全球互操作性(WiMAX)是基于电气和电子工程师协会(IEEE)802.16标准的宽带无线接入技术。移动WiMAX使用可伸缩的正交频分多址(OFDMA)方案来输送无线宽带分组数据服务到移动终端。
连同WiMAX技术的网络进入进程(process)包括初始测距、基本能力协商、认证、MAC协商(注册)、QoS协商(服务流初始化)及经动态主机配置协议(DHCP)获得IP地址。
DHCP已经是获得IP地址的方式，并且该惯例是许多操作系统中网络服务的一个集成部分。DHCP阶段在网络进入进程的最后步骤中。它通常用几秒钟通过无线网络来获得IP地址。另外，在DHCP期间缺失的分组也增大了该进程的等待时间。

具体实施方式
提出了一种用于IP(因特网协议)地址分配的方法。在一个实施例中，该方法包括由可在移动台上操作的驱动器模块在移动台发送DHCP(动态主机配置协议)发现消息前接收DHCP信息。该方法包括由驱动器模块存储DHCP信息以及将DHCP发现消息从操作系统DHCP进程重定向到驱动器模块。该方法还包括响应DHCP发现消息而执行DHCP握手(hand-shaking)。
在下面的描述中，为提供本发明的实施例的更详尽解释而陈述了许多细节。然而，本领域的技术人员将明白，本发明的实施例可在这些特定细节不存在的情况下实践。在其它情况下，公知的结构和装置以框图形式显示而未详细显示，以免混淆本发明的实施例。
随后的详细描述的一些部分根据计算机存储器内数据比特上操作的算法和符号表示来提出。这些算法描述和表示是数据处理领域技术人员用于最有效地将其工作实质传达给本领域其它技术人员的方式。算法在此处且通常被视为导致期望结果的自相一致的步骤序列。步骤是要求物理量的物理操控的那些步骤。这些量通常但不一定采用能够被存储、传送、组合、比较及以其它方式来操控的电或磁信号的形式。将这些信号称为比特、值、元素、符号、字符、项、数量或诸如此类已证明有时是方便的，主要是出于常见使用的原因。
但应记住，所有这些和类似的术语要与适当的物理量相关联，并且只是应用到这些量的方便标签。除非另有明确说明，否则，如从下面的讨论明白的，领会到在描述各处，利用例如“处理”或“计算”或“运算”或“确定”或“显示”或诸如此类的术语的讨论指计算机系统或类似电子计算装置的动作和/或进程，其操控计算机系统的寄存器和存储器内表示为物理(电)量的数据和将所述数据变换成计算机系统存储器或寄存器或其它此类信息存储、传送或显示装置内类似地表示为物理量的其它数据。
本发明的实施例还涉及用于执行本文中的操作的设备。一些设备可为了要求的目的而被专门构建，或者它可包括由计算机中存储的计算机程序选择性地激活或重新配置的通用计算机。此类计算机程序可存储在计算机可读存储媒体上，例如但不限于包括软盘、光盘、CD-ROM、DVD-ROM和磁光盘的任何类型的盘、只读存储器(ROM)、随机存取存储器(RAM)、EPROM、EEPROM、NVRAM、磁卡或光学卡或适用于存储电子指令并且各自耦合到计算机系统总线的任何类型的媒体。
本文中提出的算法和显示并未固有地涉及任何特定计算机或其它设备。各种通用系统可根据本文中的教导与程序一起被使用，或者可证明构建更专业化设备以执行要求的方法步骤是方便的。多个这些系统的要求的结构将显现于下面的描述。另外，本发明实施例未参照任何特定编程语言来描述。将领会到，各种编程语言可用于实现如本文所述的本发明的教导。
机器可读媒体包括用于以机器(例如，计算机)可读形式存储或传送信息的任何机制。例如，机器可读媒体可包括只读存储器(“ROM”)、随机存取存储器(“RAM”)、磁盘存储媒体、光存储媒体、闪速存储器装置等。
本文中所述的方法和设备针对IP地址分配。具体而言，参照多核处理器计算机系统讨论了IP地址分配。然而，用于IP地址分配的方法和设备并不受限于此，因为它们可在任何集成电路装置或系统上实现或与其相关联实现，例如蜂窝电话、个人数字助理、嵌入式控制器、移动平台、桌面平台及服务器平台，以及它们可连同例如硬件/软件线程的其它资源来实现。
概述
提出一种用于IP(即，因特网协议)地址分配的方法。在一个实施例中，该方法包括由可在移动台上操作的驱动器模块在移动台发送DHCP(动态主机配置协议)发现消息前接收DHCP信息。该方法包括由驱动器模块存储DHCP信息以及将DHCP发现消息从操作系统DHCP进程重定向到驱动器模块。该方法还包括响应DHCP发现消息而执行DHCP握手。
图1示出连同注册阶段获得IP地址的进程的一个实施例的流程图。许多有关的组件外围设备未示出以避免混淆本发明。参照图1，系统包括ASN(接入服务网络)网关101、基站102和移动台103。
在一个实施例中，ASN网关101也是DHCP代理(proxy)服务器或DHCP服务器。在一个实施例中，ASN控制由ASN网关101和基站102来处理。ASN网关101的控制平台处理无线电独立的控制，并且特征集包括授权、认证和记帐(AAA)、上下文管理、简档(profile)管理、服务流授权、寻呼、无线电资源管理及切换。ASN网关101的数据平面特征集包括映射无线电承载到IP网络、分组检查、隧道化、准入(admission)控制、监管(policing)、QoS(服务质量)测量及数据转发。
在一个实施例中，ASN网关101具有认证器和密钥分发器，以与AAA中继器一起实现AAA框架，以便将信号传送到AAA服务器，其中，在网络重新进入期间用户凭据通过EAP认证被验证。安全性上下文在AAA会话期间被创建，并且密钥(MSK和PSK)被生成并与基站102和移动台103共享。ASN网关101中的AAA模块为记帐提供流信息，因为有关流的详细信息(例如，传输或接收的比特数量、持续时间和应用的策略)存在并可从数据平面直接检索。
在一个实施例中，ASN网关101执行简档管理及驻留在连接性网络中的策略功能。简档管理识别用户和预订的凭据(例如，允许的QoS速率、流的数量、流的类型)。
在一个实施例中，ASN网关101是可操作以分配IP地址到移动台103的网关。在一个实施例中，ASN网关101包括多个基站，包括基站102。移动台103经基站102与ASN网关101进行通信。
在一个实施例中，移动台103执行到与ASN网关101相关联的网络的网络进入。响应于网络进入，ASN网关101在接收从移动台103发送的DHCP发现消息前生成DHCP信息。DHCP信息包括要指派到移动台103的IP地址和协同网络协议的其它配置数据。在一个实施例中，基站102将DHCP信息传播到移动台103。
在一个实施例中，在初始网络进入进程期间，ASN网关101连同MAC协商消息(例如，MAC附连响应110)，将DHCP信息发送到基站102。在一个实施例中，基站102连同例如注册响应(REG-RSP)111的注册消息，将DHCP信息传播到移动台103。在一个实施例中，MAC协商消息是MS附连响应，并且注册消息是REG-RSP消息。
在一个实施例中，移动台103在网络进入的注册阶段期间接收IP地址和另外的IP配置信息(例如，DHCP选项)。移动台103以未经请求的(unsolicited)方式(或在移动台103发送DHCP发现消息之前)经REG-RSP(MAC管理消息)来接收DHCP信息。DHCP信息包括要指派到移动台103的IP地址和有关默认网关、子网掩码和租赁时间的配置数据。
在一个实施例中，移动台103包括DHCP驱动器模块(未示出)。连同无线(例如，802.16m)接口驱动器在移动台103上安装DHCP驱动器模块(充当伪装(spoof)、隐藏代理或代理器(agent))。在一个实施例中，预期操作系统(OS)提供的DHCP服务不会更改。OS像平常一样执行DHCP。DHCP驱动器模块截取来自/引导至OS堆栈的DHCP消息。连同上述进程，驱动器模块从无线网络获得IP地址。驱动器模块通过DHCP信息来响应OS堆栈。
在一个实施例中，驱动器模块能够生成REG-REQ消息，指示移动台103能够连同REG-RSP消息来接收DHCP信息。驱动器模块通过DHCPOS服务(OS进程)将DHCP发现消息重定向到其自己并执行DHCP握手。DHCP握手包括：生成对DHCP发现消息的响应而不向远程DHCP网关发出请求，将DHCP信息传递到DHCPOS服务，以及将DHCP确认传递到OSDHCP服务。
在一个实施例中，连同高级空中接口(AAI)来执行IP分配进程。在一个实施例中，连同AAI_REG-REQ，主机配置能力和参数包括：1)主机配置能力指示符IE(信息元素)：指示AMS(高级移动台)是否支持使用通过AAIREG-RSP消息接收的参数来配置主机的能力。如果请求的主机配置IE包括在消息中，则不包括该1比特指示符；以及2)请求的主机配置IE：包括DHCP选项格式中的请求的主机配置选项。如果被包括，此IE指示AMS支持使用AAIREG-RSP消息的主机配置，并且主机配置能力指示符IE将被省略。
在一个实施例中，连同AAI_REG-RSP，主机配置能力和参数包括：1)IPv6归属网络前缀IE：用于AMS的分配的IPv6归属网络前缀；以及2)另外的主机配置IE：包括DHCP选项格式中的另外的主机配置选项。
在一个实施例中，IP分配方法适用于各种无线移动网络标准，例如，IEEE802.16m、长期演进(LTE)及其扩展。
图2示出连同服务流设置阶段来获得IP地址的进程的一个实施例的流程图。
在一个实施例中，在初始网络进入过程期间，ASN网关201连同路径注册消息，将DHCP信息发送到基站202。基站202连同服务流配置消息，将DHCP信息传播到移动台203。在一个实施例中，路径注册消息是PATH-REG响应，并且服务流配置消息是DSA-RSP消息。
在一个实施例中，移动台203在初始服务流设置期间接收IP地址和另外的IP配置信息(例如，DHCP选项)。ASN网关201中的DHCP代理经Path-REG-RSP210在移动台203的初始网络进入进程期间将DHCP信息发送到基站202。移动台203以未经请求的方式(不由移动台203来请求)在初始服务流设置期间经DSA-RSP211(MAC管理消息)从基站202接收DHCP信息。
图3示出由基站启动的获得IP地址的进程的一个实施例的流程图。
在一个实施例中，基站302连同DHCP消息传递，从ASN网关301请求DHCP信息。在一个实施例中，DHCP消息传递包括DHCP发现310、DHCP供应311、DHCP请求312及DHCPACK313。基站302经“服务流更改”消息将DHCP信息传播到移动台303。在一个实施例中，服务流更改消息是DSC-RSP消息。
在一个实施例中，在移动台303的初始网络进入完成并且初始服务流被建立后，基站302与代表移动台303与ASN网关301中的DHCP代理执行DHCP消息传递。基站302获得用于移动台303的IP地址和IP配置信息。基站经DSC-RSP(MAC管理消息)将IP地址和IP配置信息提供到移动台。

虽然在阅读前面的描述后，本领域的技术人员将毫无疑问明白本发明的实施例的许多变化和修改，但要理解，通过说明方式而显示和描述的任何特定实施例绝非旨在被视为是限制性的。因此，对各种实施例细节的引用并非旨在限制权利要求的范围，权利要求本身只记载被认为对本发明是必需的那些特征。
