Description

单 PDP双栈串行拨号方法和系统 技术领域 本发明涉及移动通信领域， 具体涉及一种单 PDP双栈串行拨号方法和系统。 背景技术 与 IPv4 ( Internet Protocol version 4，因特网协议版本 4 )相比， IPv6 ( Internet Protocol version 6, 因特网协议版本 6)具有诸多优点。无论是 3GPP (3rd Generation Partnership Project, 第三代移动通信伙伴计划） 的 UMTS (Universal Mobile Telecommunication System, 通用移动通信系统）， 还是 3GPP2 (3rd Generation Partnership Project 2, 第三 代移动通信伙伴计划 2) 的 CDMA2000系统， 都早已确定了 IPv6的发展方向。 特别 是在 3G (第三代移动通信） 的 IMS (IP Multimedia Sub-system, IP多媒体子系统） 阶 段， 网络系统将全面基于或兼容 IPv6。 IPv6已成为互联网和移动通信网的共用基本协 议。 在这样的背景下， IPv6在 3G网络和移动终端中的应用将越来越普及。 但是，在 IPv6在移动通信领域普及的过程中， IPv4在相当一段时间内也将长期存 在， 因此移动终端和网络设备往往需要同时兼容 IPv4和 IPv6， 即支持 IPv4和 IPv6双 栈。 对移动终端来说， 支持双栈意味着在拨号过程中， 需要按照一定的流程激活相应 类型的 PDP上下文 （Packet Data Protocol context分组数据协议上下文）。 最常用的一 种情况是， 终端可以尝试激活类型为 IPv4v6的 PDP， 即尝试建立单 PDP双栈的连接。 在 PC上， 通过移动终端建立单 PDP双栈连接时， 需要同时下发 IPv4和 IPv6的拨号 指令。而 Mac等操作系统下的主机驱动和终端之间的通信机制如果采用的是同步通信 机制， 即它们之间采用串行方式进行交互， 在这种情况下， 采用串行方法下发两条拨 号指令时， 会出现单 PDP双栈自动回退到双 PDP双栈的问题， 且由于移动终端所述 的网络环境多样化， 网络可能不支持单 PDP双栈， 或根本不支持 IPv6或 IPv4等， 此 时盲目的拨号将发生不必要的拨号处理和拨号失败的情况， 浪费系统资源。 发明内容 本发明提供了一种单 PDP双栈串行拨号方法和系统， 可精简拨号流程， 提高拨号 效率和系统资源的利用率。 根据本发明的一个方面， 提供一种单 PDP双栈串行拨号方法， 包括以下步骤： 移动终端根据主机发送的参数设置命令设置单 PDP双栈串行拨号参数； 移动终端根据主机发送的第一拨号指令和单 PDP双栈串行拨号参数向移动通信网 络发起 PDP激活请求， 并获取移动通信网络反馈的激活响应信息； 移动终端根据激活响应信息生成拨号响应信息反馈给主机， 拨号响应信息包括原 因参考信息； 主机根据拨号响应信息确定拨号方式。 在本发明的一种实施例中， 激活响应信息包括激活结果和激活参考信息， 移动终 端根据激活响应信息生成拨号响应信息包括： 移动终端根据激活结果判断 PDP激活是否成功， 如是， 则根据激活参考信息生成 拨号成功响应信息或拨号失败响应信息； 否则， 根据激活参考信息生成拨号失败响应 信息。 在本发明的一种实施例中， 激活参考信息包括激活类型信息和拒绝原因信息， 在
PDP激活成功时， 移动终端根据激活参考信息生成拨号响应信息包括： 移动终端根据激活类型信息判断激活的 PDP 类型是否是第一拨号指令请求的类 型， 如是， 根据拒绝原因信息得到原因参考信息并生成拨号成功响应信息； 否则， 判 断激活的 PDP类型是否是 IPv4v6类型， 如是， 根据拒绝原因信息得到原因参考信息 并生成拨号成功响应信息， 此时拒绝原因信息包含任何原因， 否则， 根据拒绝原因信 息得到原因参考信息并生成拨号失败响应信息。 在本发明的一种实施例中，激活参考信息包括拒绝原因信息，在 PDP激活失败时， 移动终端根据激活参考信息生成拨号失败响应信息包括： 移动终端根据拒绝原因信息判断失败原因是否是第一拨号指令发起的 PDP激活请 求的 PDP地址或 PDP类型未知， 如是， 则记录原因参考信息为"未知 PDP地址或未知 PDP类型"， 否则， 记录原因参考信息为"未知原因"； 根据记录的原因参考信息生成拨号失败响应信息。 在本发明的一种实施例中， 第一拨号指令为 IPv4拨号指令， 移动终端根据激活参 考信息生成拨号响应信息包括： 若移动终端根据激活类型信息判断激活的 PDP类型是 IPv4类型， 移动终端根据 拒绝原因信息判断未激活 IPv6类型的原因是否是只支持 IPv4类型,如是， 则记录原因 参考信息为"只支持 IPv4类型"； 否则， 判断未激活 IPv6类型的原因是否是只支持单 地址， 如是， 则记录原因参考信息为"只支持单地址"； 若拒绝原因信息中未包含任何 原因， 也记录原因参考信息为"只支持单地址"； 根据得到的原因参考信息生成拨号成 功响应信息； 若移动终端根据激活类型信息判断激活的 PDP 类型不是第一拨号指令请求的 IPv4类型， 则进一步判断激活类型是否为 IPv4v6类型； 如是， 则此时拒绝原因信息不 包含任何原因， 记录原因参考信息为 "成功"， 根据得到的原因参考信息生成拨号成功 响应信息； 否则， 判断失败原因是否为只支持 IPv6类型， 如是， 则记录原因参考信息 为"只支持第 IPv6类型"， 并将已激活的 IPv6类型的 PDP去激活； 否则， 判断未激活 IPv4类型的原因是否是只支持单地址，如是， 则记录原因参考信息为"只支持单地址"； 若拒绝原因信息中未包含任何原因， 也记录原因参考信息为"只支持单地址"， 根据得 到的原因参考信息生成拨号失败的响应信息。 在本发明的一种实施例中， 第一拨号指令为 IPv6拨号指令， 移动终端根据激活参 考信息生成拨号响应信息包括： 若移动终端根据激活类型信息判断激活的 PDP类型是 IPv6类型， 移动终端根据 拒绝原因信息判断未激活 IPv4类型的原因是否是只支持 IPv6类型,如是， 则记录原因 参考信息为"只支持第 IPv6类型"； 否则， 判断未激活 IPv4类型的原因是否是只支持 单地址， 如是， 则记录原因参考信息为"只支持单地址"； 若拒绝原因信息中未包含任 何原因， 也记录原因参考信息为"只支持单地址"； 根据得到的原因参考信息生成拨号 成功响应信息； 若移动终端根据激活类型信息判断激活的 PDP 类型不是第一拨号指令请求的 IPv6型， 则进一步判断激活类型是否为 IPv4v6类型； 如是， 则此时拒绝原因信息不包 含任何原因， 记录原因参考信息为 "成功"， 根据得到的原因参考信息生成拨号成功响 应信息； 否则， 判断失败原因是否为只支持 IPv4类型， 如是， 则记录原因参考信息为 "只支持 IPv4类型"， 并将已激活的 IPv4类型的 PDP去激活； 否则， 判断未激活 IPv6 类型的原因是否是只支持单地址， 如是， 则记录原因参考信息为"只支持单地址"； 若 拒绝原因信息中未包含任何原因， 也记录原因参考信息为"只支持单地址"， 根据得到 的原因参考信息生成拨号失败的响应信息。 在本发明的一种实施例中， 主机根据拨号响应信息确定拨号方式包括： 主机判断拨号失败响应信息包含的原因参考信息是"未知 PDP地址或未知 PDP类 型"时， 主机回退进行下发第一拨号指令进行单栈拨号； 主机判断拨号失败响应信息包含的原因参考信息是"未知原因"时， 主机下发与第 一拨号指令不同的另一拨号指令进行拨号。 在本发明的一种实施例中， 主机根据拨号响应信息确定拨号方式包括： 若接收到的拨号响应信息是拨号成功响应信息， 主机判断拨号成功响应信息包含 的原因参考信息是"只支持 IPv4类型"时， 主机不再下发 IPv6拨号指令； 主机判断拨 号成功响应信息包含的原因参考信息是"只支持单地址 "时， 主机在新的端口下发 IPv6 单栈拨号；主机判断拨号成功响应信息包含的原因参考信息是"成功"时，主机下发 IPv6 拨号指令； 若接收到的拨号响应信息是拨号失败响应信息， 主机判断拨号失败响应信息包含 的原因参考信息是"只支持第 IPv6类型"时， 主机回退进行 IPv6单栈的拨号； 主机判 断拨号失败响应信息包含的原因参考信息是"只支持单地址 "时， 主机退回进行双 PDP 双栈的拨号。 在本发明的一种实施例中， 主机根据拨号响应信息确定拨号方式包括： 若接收到的拨号响应信息是拨号成功响应信息， 主机判断拨号成功响应信息包含 的原因参考信息是"只支持第 IPv6类型"时， 主机不再下发 IPv4拨号指令； 主机判断 拨号成功响应信息包含的原因参考信息是 "只支持单地址"， 主机在新的端口下发 IPv4 单栈拨号；主机判断拨号成功响应信息包含的原因参考信息是"成功"时，主机下发 IPv4 拨号指令； 若接收到的拨号响应信息是拨号失败响应信息， 主机判断拨号失败响应信息包含 的原因参考信息是"只支持 IPv4类型"时， 主机回退进行 IPv4单栈的拨号； 主机判断 拨号失败响应信息包含的原因参考信息是 "只支持单地址"时， 主机退回进行双 PDP双 栈的拨号。 在本发明的一种实施例中， 第一拨号指令是主机向移动终端发送的第一条拨号指 令。 本发明还提供了一种单 PDP双栈串行拨号系统， 该系统包括： 主机、 移动终端； 其中， 主机包括： 连接管理单元， 设置为向移动终端发送参数设置命令以及第一拨号 指令， 并接收移动终端反馈的拨号响应信息； 原因解析处理单元， 设置为连对接管理 单元接收到的拨号响应信息的原因参考信息确定拨号方式； 移动终端包括： 参数管理单元， 设置为根据主机的连接管理单元发送的参数设置 命令设置单 PDP双栈串行拨号参数； 会话管理单元， 设置为根据主机发送的第一拨号 指令和单 PDP双栈串行拨号参数向移动通信网络发起 PDP激活请求， 并获取移动通 信网络反馈的激活响应信息； 信息反馈单元， 设置为根据激活响应信息生成拨号响应 信息， 通过会话管理单元反馈给主机， 拨号响应信息包括原因参考信息。 本发明的有益效果是： 本发明中的移动终端根据主机发送的参数设置命令设置单 PDP 双栈串行拨号参 数；然后根据主机发送的第一拨号指令和配置的单 PDP双栈串行拨号参数向移动通信 网络发起 PDP激活请求， 获取移动通信网络反馈的激活响应信息， 根据该激活响应信 息生成拨号响应信息反馈给主机， 切反馈的拨号响应信息包括原因参考信息； 主机接 收到该拨号响应信息后， 即可根据该拨号信息包括的原因参考信息获取当前移动网络 的具体情况而确定拨号方式。 例如主机根据该原因参考信息得知当前网络不支持 IPv6 时， 则主机即可确定在后续的过程中不需要再发送 IPv6拨号指令， 因为此时即使发送 拨号也不会成功， 因此可避免不必要的拨号处理和拨号失败的情况， 以及可避免在不 必要的情况下退回到双 PDP栈拨号的情况， 可精简拨号流程， 提高拨号效率和系统资 源的利用率。 附图说明 图 1为本发明一种实施例的单 PDP双栈串行拨号系统结构示意图； 图 2为本发明一种实施例的单 PDP双栈串行拨号流程示意图一； 以及 图 3为本发明一种实施例的单 PDP双栈串行拨号流程示意图二。 具体实施方式 下面通过具体实施方式结合附图对本发明作进一步详细说明。 请参考图 1， 本实施例中的单 PDP双栈串行拨号系统包括主机、 移动终端； 移动终端包括依次连接的参数管理单元、 会话管理单元和信息反馈单元， 其中， 参数管理单元设置为接收主机的连接管理单元发送的参数设置命令并根据该命令 设置、 保存单 PDP双栈串行拨号参数； 会话管理单元， 设置为根据主机发送的第一拨号指令和参数管理单元设置保存的 单 PDP双栈串行拨号参数向移动通信网络发起 PDP激活请求， 并获取移动通信网络 反馈的激活响应信息， 该激活响应信息中包括激活结果和激活参考信息， 激活参考信 息则进一步包括激活类型和拒绝原因信息； 信息反馈单元， 设置为根据激活响应信息生成拨号响应信息， 生成的拨号响应信 息包含根据激活结果和激活参考信息记录的各种激活结果中针对激活失败的情况原 因， 并通过会话管理单元将拨号响应信息反馈给主机。 主机包括连接管理单元和与连接管理单元连接的原因解析处理单元； 其中， 连接管理单元设置为向与之通信连接的移动终端发送参数设置命令以及第一拨号 指令， 该第一拨号指令为连接管理单元向移动终端发送的第一条拨号指令； 以及还设 置为接收移动终端反馈的拨号响应信息， 该拨号响应信息里包含用于记录各种激活结 果中针对激活失败的情况原因的原因参考信息， 并将接收到的拨号响应信息发送给原 因解析处理单元处理； 原因解析处理单元则设置为对连接管理单元接收到的拨号响应信息的原因参考信 息所记录的各种原因了解当前通信的移动通信网络的情况，进而确定后续的拨号方式。 移动终端的信息反馈单元根据移动通信网络反馈的激活响应信息生成拨号响应信 息具体可包括： 移动终端的信息反馈单元根据网络反馈的激活响应信包含的激活结果 判断第一拨号指令请求的 PDP激活是否成功， 如成功， 则根据该激活响应信息包含的 激活参考信息生成拨号成功响应信息或拨号失败响应信息， 具体生成拨号成功响应信 息还是拨号失败响应信息， 需进一步对激活的类型进行判断而确认； 如果根据激活结 果判断第一拨号指令请求的 PDP激活失败，则直接根据该激活参考信息生成拨号失败 响应信息； 上述过程具体如下： 在第一拨号指令请求的 PDP激活成功时，移动终端的信息反馈单元根据激活参考 信息生成拨号响应信息包括： 根据激活参考信息包括的激活类型信息判断激活的 PDP类型是否是第一拨号指令 请求的类型， 如是， 则拨号成功， 根据激活参考信息包括的拒绝原因信息得到原因参 考信息并生成拨号成功响应信息； 否则， 需进一步判断激活的 PDP类型是否是 IPv4v6 类型， 如果是， 则拨号成功， 此时网络反馈的激活参考信息包含的拒绝原因信息为空， 即未包含任何原因， 然后根据拒绝原因信息得到原因参考信息并生成拨号成功响应信 息； 如果不是 IPv4v6类型， 则拨号失败， 根据拒绝原因信息得到原因参考信息并生成 拨号失败响应信息。 下面以第一拨号指令为 IPv4拨号指令和 IPv6拨号指令为例对本 发明做进一步的说明： 当第一拨号指令为 IPv4拨号指令时， 若根据激活类型信息判断激活的 PDP类型 是 IPv4类型， 则激活的类型与是第一拨号指令请求的类型， 拨号成功， 此时移动终端 需根据网络反馈的拒绝原因信息判断未激活 IPv6类型的原因是否是只支持 IPv4类型, 如是， 则记录原因参考信息为 "只支持 IPv4类型"， 本实施例中设其代号为 50;
