附图概述
图 1 是本发明实施例的双网双待终端进行通讯的装置示意图;
图 2是本发明应用示例的双网双待终端进行通讯的装置示意图。
本发明的较佳实施方式
在本发明中, 主要针对双网双待终端釆用双调制解调模块(Modem ) 架 构的双网双待单卡单号的情况。 如图 1 所示, 双网双待终端包括应用 ( AP )子***、 3G无线通讯子系 统、 2G无线通讯子***和身份识别模块( SIM卡模块 ) , 所述身份识别模块 中插有一身份识别卡(SIM卡) , 该身份识别卡中保存有用于 2G网络和 3G 网络进行身份认证的信息, 所述 2G无线通讯子***分别与应用子***、 身 份识别模块和 3G无线通讯子***连接,所述 3G无线通讯子***分别与应用
子***、 身份识别模块和 2G无线通讯子***连接。
3G无线通讯子***和 2G无线通讯子***组成无线通讯( CP )子***。 在本发明中, 两个无线通讯子***(两个 Modem )都和 SIM卡模块进行 物理连接, 并且 2个 Modem之间通过控制管脚以实现对 SIM卡的并发访问。 AP子***可对 2个 Modem进行策略管理, 实现 CS、 PS业务分流。
具体地, 所述 2G无线通讯子***读取身份识别模块中身份识别卡中的 信息, 使用所述身份识别卡中的信息, 与 2G网络通讯; 所述 3G无线通讯子 ***读取所述身份识别模块中身份识别卡中的信息, 使用所述身份识别卡中 的信息, 与 3G网络通讯。
为了解决 2个 Modem同时读写 SIM卡问题, 使 2G无线通讯子***和
3G无线通讯子***读写互斥, 即:
当所述 2G无线通讯子***读写所述身份识别模块中身份识别卡中的信 息时, 禁止所述 3G无线通讯子***读写所述身份识别卡中的信息;
当所述 3G无线通讯子***读写所述身份识别模块中身份识别卡中的信 息时, 禁止所述 2G无线通讯子***读写所述身份识别卡中的信息。
具体实现时, 可在两个无线通讯子***之间增加 2 个通用输入 /输出 ( General Purpose Input Output, GPIO )作为控制管脚(第一控制管脚和第二 控制管脚) , 用于对身份识别卡的并发操作控制。
2G无线通讯子***通过自身的第一控制管脚与所述 3G无线通讯子*** 相连,所述 3G无线通讯子***通过自身的第二控制管脚与所述 3G无线通讯 子***相连;
在所述 2G无线通讯子***读写身份识别模块中身份识别卡中的信息前, 先读取第二控制管脚的状态, 当所述第二控制管脚的状态为低电平时再执行 读写操作, 并设置第一控制管脚为高电平, 从而禁止所述 3G无线通讯子系 统读写所述身份识别卡中的信息; 所述 2G无线通讯子***读写完毕后设置 所述第一控制管脚为低电平;
在所述 3G无线通讯子***读写身份识别模块中身份识别卡中的信息前, 先读取第一控制管脚的状态, 当所述第一控制管脚的状态为低电平时再执行
读写操作, 并设置第二控制管脚为高电平, 从而禁止所述 2G无线通讯子系 统读写所述身份识别卡中的信息; 所述 3G无线通讯子***读写完毕后设置 所述第二控制管脚为低电平。
其中, 在与 2G/3G网络通讯的过程中, 通常只执行对该身份识别卡的读 操作; 对身份识别卡的写操作包括将通讯录或短信写入到身份识别卡。
应用子***可以在无线接口层( Radio interface Layer, RIL )构建一个 2/3G 业务管理模块, 当所述双网双待终端开机时, 该业务管理模块先控制 3G无 线通讯子***和 2G无线通讯子***中的一个开机, 再控制另外一个开机。 另外, 该业务管理模块可用于保存 2/3G无线通讯子***在开机时上报的通 讯录信息和短消息信息、 开机后根据 2个无线通讯子***负责的业务类型及 当前的信号强度状态, 调整业务策略以实现 CS、 PS业务分流。
上述 CS、 PS业务分流的策略是指: 针对 3G网络带宽较大, 适合数据业 务, 而 2G网络优化工作积累较多, 对语音等 2G业务支持较好的特点, 在终 端侧利用 2G、 3G双网双待实现 PS (分组业务) 、 CS (电路业务)业务分流 (即 2G网络承载 CS业务, 3G网络承载 PS数据业务 ) , 规避当前 2、 3G网 络共存带来的问题。
具体地, 当所述双网双待终端的用户发起业务时, 所述业务管理模块按 照业务类型选择网络, 当所发起的业务为 PS业务, 或者为 CS业务中的可视 电话业务时, 所述业务管理模块选择 3G 网络, 当所发起的业务为除可视电 话业务以外的 CS业务时, 所述业务管理模块选择 2G网络; 当所选择的网络 满足信号强度的条件时, 所选择的网络对应的无线通讯子***通过所选择的 网络进行通讯。
其中, 3G无线通讯子***监测当前 3G网络的信号强度, 并将当前 3G 网络的信号强度告知所述业务管理模块; 当业务管理模块选择 3G 网络, 且 3G网络满足信号强度的条件时, 通过 3G网络进行通讯; 当业务管理模块选 择 2G网络, 且 2G网络满足信号强度的条件时, 2G无线通讯子***通过 2G 网络进行通讯。
其中, 可视电话业务虽然^ ^于 CS电路域的业务, 由于必须通过 3G网 络进行业务承载, 所以当用户发起可视电话业务时, 需要选择 3 G网络。
上述满足信号强度的条件是指, 网络的信号强度可承载相关业务(即所 发起的业务) 。 具体实现时, 可以是当网络的信号强度大于指定门限值时, 判断满足信号强度的条件。
在本发明中, 可釆用如下方式对所发起的 PS业务进行调整, 包括: 1、 当所发起的业务为 PS业务, 所述业务管理模块选择 3G网络时, 若 所述业务管理模块根据所述 3G无线通讯子***监测到的当前 3G网络的信号 强度, 判断无法发起所述 PS业务时, 通知所述 2G无线通讯子***激活 2G 网络的 2G数据链路, 发起所述业务;
2、 当所发起的业务为 PS业务, 所述 3G无线通讯子***通过 3G网络进 行通讯的过程中, 若所述业务管理模块根据所述 3G无线通讯子***监测到 的当前 3G网络的信号强度,判断当前 3G网络的信号强度减弱到无法承载所 述 PS业务时, 则所述业务管理模块通知所述 3G无线通讯子***和 2G无线 通讯子***,将所述 PS业务对应的分组数据协议( Packet Data Protocol, PDP ) 数据链路从 3G数据链路切换到 2G数据链路。
3、 所述 2G无线通讯子***使用 2G数据链路进行 PS业务时, 当所述业 务管理模块根据所述 3G无线通讯子***监测到的当前 3G网络的信号强度, 判断当前 3G网络的信号强度增强到可承载所述 PS业务时, 则所述业务管理 模块通知所述 3G无线通讯子***和 2G无线通讯子***, 将所述 PS业务对 应的 PDP数据链路从 2G数据链路切换到 3G数据链路。
具体实现时, 可以是业务管理模块判断当前 3G 网络的信号强度, 若小 于等于指定门限值, 则判定无法发起所述 PS业务或承载所述 PS业务, 若大 于指定门限值, 则判定可承载所述 PS业务。 当然, 上述三种情况所使用的指 定门限值可以相等, 也可以不等。
另夕卜, 针对所发起的业务为可视电话业务, 但业务管理模块根据所述 3G 无线通讯子***监测到的当前 3G 网络的信号强度, 判断无法发起所述可视 电话业务的情况, 业务管理模块控制将该可视电话业务回落到普通的语音业 务, 再通知 2G无线通讯子***发起该语音业务。
上述 3G网络可以是 TD网络、 宽带码分多址(Wideband Code Division
Multiple Access, WCDMA ) 网络、 CDMA2000网络, 2G网络可以是 GSM 网络、 码分多址( Code Division Multiple Access, CDMA ) 网络等, 在本发明 的实施例和应用实例中, 主要以 3G网络为 TD网络, 2G网络为 GSM网络 进行描述,但不限于此,其它类型的 3G网络和 2G网络也同样适用于本发明。
下面以 3G网络为 TD网络, 2G网络为 GSM网络的应用实例进一步描 述。
如图 2所示,本实例运用 "ΑΡ(应用)+ TD Modem (无线)+ GSM Modem (无线) " 三核架构的 TD/GSM双网双待手机来实现 CS、 PS业务的 23G网 络承载分流, 其中 AP部分是负责应用的主模块, 两个无线通讯子*** TD Modem和 GSM Modem分别负责与 2G、 3G网络的交互。 为了实现两个无线 模块共同使用一张 SIM卡的功能,两个无线 Modem之间增加 2个 GPIO作为 对 SIM卡的并发操作控制。 在 AP的 RIL层构建出一个 2/3G业务管理模块, 在开机时, AP先对其中一个 Modem上电, 比如 GSM Modem, 然后再对 TD Modem上电。 在开机过程中 2个 Modem存在同时读写 SIM卡的情况 , 这时 候需要通过 GPIO对 SIM卡读写控制, 比如当 GSM Modem读写 SIM卡时, 先把 GPIOa (第一控制管脚)拉高, 这样 TD Modem在读写 SIM卡前, 先读 取 GPIOa的状态, 如果为高, 就暂不读写; 如果为低, 就可读写; 同理, TD Modem在读写 SIM卡时, 先把 GPIOb (第二控制管脚 )拉高, 这样就可以通 知 GSM Modem暂不读写 SIM卡。 通过 GPIO对 SIM卡的有效控制管理, 实 现理论上的两个独立的无线通讯模块访问同一张 SIM卡的功能, 达到双网双 待单卡单号的目的。 如图 2所示, 本实施例的基于双网双待单卡单号实现 23G双网双待终端 CS、 PS业务分流的装置包括以下模块:
A、 AP (应用)子***
AP子***具有独立 CPU的应用处理器模块, 是手机终端的主控***, 负责完成和用户的交互, 如果用户需要进行无线通讯方面或者 SIM卡方面的 操作, 则由该***负责控制相应的无线通讯***完成相关功能。 在本实例中 该子***包含一业务管理模块, 该模块有以下功能:
1、 按 "CS业务走 2G网络, PS业务走 3G网络" 原则, 对各个业务进
行分类, 当用户发起业务时, 判断如果是 CS业务, 则从 GSM无线通讯子系 统发起,如果是 PS业务,则从 TD无线通讯子***发起。其中,鉴于 CS64kbps 可视电话是 TD网络特有业务,所以可视电话业务也是通过 TD无线通讯子系 统发起。
2、 根据 TD无线通讯子***负责监测的所处 TD网络信号强度对终端当 前的 PS业务策略进行调整。 如:
当 TD无线通讯子***监测的所处 TD网络信号强度不足以支撑发起相关 数据业务时, 业务管理模块能通过 GSM无线通讯子***激活 2G数据链路来 发起相关业务。
当终端正在使用默认的 TD 网络进行数据业务过程中, 所处位置的网络 信号变弱至不足以支撑相关业务正常进行时, 业务管理模块负责将相关 PDP 数据链路切换到 GSM无线通讯子***负责的 2G数据链路上, 以延续相关业 务的正常进行。
B、 GSM无线通讯子***
GSM无线通讯子***, 负责与 GSM网络进行交互, 承载各种 CS业务, 并负责对 SIM进行初始化工作, 可包括 AT命令接口层和 GSM无线协议栈。
1、 GSM无线通讯子***包括 GSM Modem (本实例中, 可认为 GSM无 线通讯子***即为 GSM Modem ) , 主要负责整个终端除可视电话外所有 CS 电路域业务的承载,并在 TD信号不佳时通过 2G的数据链路临时承载相关数 据业务。
2、 通过 GPIO对 SIM读写进行控制, 在读写 SIM卡前, 先判断 GPIOb 的状态, 如果为高, 则不读写 SIM卡; 如果为低, 然后把 GPIOa拉高, 然后 读写 SIM卡。 读写 SIM卡结束后 , 再把 GPIOa拉低, 以通知 TD Modem可 以对 SIM卡进行读写。
C、 TD无线通讯子***
TD无线通讯子***负责与 TD网络进行交互, 承载各种 PS业务和可视
电话功能, 可包括 AT命令接口层和 TD无线协议栈。
1、 TD无线通讯子***包括 TD Modem (本实例中, 可认为 TD无线通 讯子***即为 TD Modem ) 。 本实施例的 TD Modem区别于目前正在商用的 TD Modem, 它不具备 TD/GSM双模切换功能, 仅工作在 'TD ONLY' 模式。 它主要负责基于 TD 网络的数据业务以及可视电话业务的数据交互。 以及当 前终端所处 TD网络的信号强度监测, 当信号弱至一定值时, 通知 AP应用子 ***将 PS业务切换到 GSM无线通讯子***。
2、 通过 GPIO对 SIM读写进行控制, 在读写 SIM卡前, 先判断 GPIOa 的状态, 如果为高, 则不读写 SIM卡; 如果为低, 然后把 GPIOb拉高, 然后 读写 SIM卡。 读写 SIM卡结束后, 再把 GPIOb拉低, 以通知 GSM Modem 可以对 SIM卡进行读写。
D、 SIM卡模块
SIM卡模块中插有一 SIM卡, 该 SIM卡中保存有用于 GSM网络和 TD 网络进行身份认证的信息。
在开机过程中, AP可以先对其中一个 Modem上电, 再对另一个 Modem 上电, 上电初始化过程中, 涉及到两个无线 Modem对 SIM卡的并发操作可 以通过上述的方式解决。两个无线 Modem按照各自独立的初始化流程最终完 成协议栈的初始化, 将同一张 SIM卡的国际移动用户识别码( International Mobile Subscriber Identification Number, IMSI )上 4艮各自对应的 TD网络以及 GSM网络。
以普通语音电话业务为例, 当用户通过拨号界面呼出语音电话时, 应用 子***根据 "CS业务走 GSM网络, PS业务走 TD网络" 的逻辑, 调用 GSM 无线通讯子***与 GSM网络进行交互, 并通过 GSM网络承载与对方进行业 务。 被叫时, 网络设备根据终端在网络侧注册的信息(主要是终端注册 GSM 网络使用的 IMSI号 ) ,和终端的 GSM无线通讯子***建立链接并承载业务。 短信等其他 CS业务流程也是如此。
需要说明的是, 基于 CS电路域的 TD可视电话业务, 由于需要 TD网络 进行承载, 当用户发起呼叫后, 应用子***将调用 TD无线通讯子***与 TD 网络进行交互和数据承载。 而被叫时, 网络设备根据终端在网络侧注册的信 息(主要是终端注册 TD网络使用的 IMSI号) , 和终端的 TD无线通讯子系 统建立链接并承载业务。
当用户通过浏览器上互联网时, 当用户在浏览器中输入相关网址后, 应 用子***先通过 TD无线通讯子***查询当前终端所处 TD网络的信号强度。 当应用子***得知网络信号满足要求时, 再通过 TD无线通讯子***和与之 对应的网络服务设备建立基于 TD 网络的数据链路通道并进行相关业务数据 交互。 当应用子***得知网络信号不满足要求时, 应用子***将主动通过 GSM无线通讯子***和与之对应的网络服务设备建立基于 GSM网络的数据 链路通道来替代 TD网络完成上网业务。 当然, 当终端使用默认的 TD无线通 讯子***和 TD 网络上网时, 网络信号衰变到不满足业务要求时, 终端应用 子***将通过 TD无线通讯子***主动断开基于 TD网络的 PDP数据链路, 并立即调用 GSM无线通讯子***让终端和 GSM网络建立数据链路, 已维持 上网业务的进行。 反之, 当终端临时使用 GSM无线通讯子***和 GSM网络 上网时,应用子***通过 TD无线通讯子***得知 TD网络信号恢复到满足数 据业务要求时, 又会将相关 PDP数据链路切换回 TD数据链路。
其他形式的数据业务基本与通过浏览器上网的流程类似,这里不做赞述。 不过, 彩信业务和邮件推送服务 (PushMail )邮件业务由于其业务流程中特 殊的 PUSH通知消息机制, 被动接收相关彩信以及 PushMail邮件时的交互流 程要复杂一些。 由于 PUSH通知消息属 CS电路域范畴, 网络侧将先把相关 PUSH通知消息通过 GSM网络和 GSM通讯子***送达终端的应用子***, 应用子***再根据当前网络情况并按照相关 PS业务策略进行调度。

工业实用性 本发明所述方法和装置, 仅使用单 SIM卡就实现了双网双待功能, 与其 他双网双待双卡双号的终端相比, 有利于硬件和结构件设计, 节约了成本。 与现有的 2/3G双模单待终端技术相比, 本发明在兼顾了 2G网络 CS电路域 业务专长以及 3G 网络的数据业务专长的同时, 通过双网双待技术减少了双 模切换几率(仅在数据业务时有部分切换),也就从根本上减少和避免了 2/3G 双模单待终端因为 "2、 3G双模切换" 策略所导致的网络重选频繁, 耗电严 重, 通话掉话, 脱网等故障。 提高了终端的用户使用感受, 也推动了 TD 网 络的发展。
