一种终端选择网络方法及双待终端
技术领域
本发明涉及通信技术领域, 特别涉及一种终端选择网络方法及双待 终端。 发明背景
在无线通信技术领域, 存在多种网络, 例如第二代通信技术(2G, Second Generation ) 网络、 第三代通信技术( 3G, Third Generation ) 网 络和长期演进( LTE, Long Term Evolution )网络等, 基于上述不同网络 的业务主要包括语音业务和数据业务,其中语音业务由电路交换域(CS, Circuit Switched Domain )来承载, 筒称为 CS域业务, 数据业务由分组 交换域(PS, Packet Switched Domain )来承载, 筒称为 PS域业务。
上述不同网络中, 有些新兴网络的网络覆盖并不成熟, 在实际使用 时可能出现没有信号的情况,影响了用户体验, 以 2G网络及 3G网络为 例, 由于 3G网络为新兴的网络, 不如 2G网络成熟, 因此, 其信号覆盖 没有 2G网络的好。 为了改善用户体验, 现有的 3G网络的终端 (如 3G 手机)一般也同时支持 2G网络, 以便在 3G信号差的时候重选到 2G网 络。 这里称这类既支持 2G网络又支持 3G网络的终端为 "双模终端" (典 型的如 WCDMA/GSM双模手机, 或者 TD-SCDMA/GSM双模手机)。
参见图 1 , 为现有技术中常见的双模终端的结构示意图, 为了说明 方便, 这里只列出几个主要的功能模块, 包括:
SIM卡, SIM卡代理模块, 应用程序, 业务适配模块, 2G/3G协议 栈处理模块, 2G/3G物理层处理模块, 2G/3G射频处理模块以及天线, 其中:
SIM卡用于存储用户的一些信息,包括用户在 2G网络以及 3G网络 的信息, 如这里的 SIM卡可以使用 3G网络经常用的 USIM卡;
SIM卡代理模块用于在 2G/3G协议栈处理模块访问 SIM卡时进行代 理,使之能够在 2G以及 3G网络访问 SIM卡中对应的 2G或 3G用户信 息;
应用程序是指终端中跟业务或控制有关的一些程序;
业务适配模块用于连接应用程序以及 2G/3G协议栈处理模块, 主要 用于根据 2G/3G协议栈的驻留状态, 选择合适的协议栈传输业务。
2G/3G协议栈处理模块用于处理 2G以及 3G相关的协议,这里的协 议一般是指物理层以上的协议, 如 MAC/RLC/RRC等。
2G/3G物理层处理模块用于处理 2G以及 3G物理层相关的协议; 2G/3G射频处理模块用于完成 2G 以及 3G射频模块相关的处理功 h · 天线进行完成 2G以及 3G信号的接收以及发射。
基于上述单卡双模终端优先驻留在 3G网络, 通过 2G/3G协议栈处 理模块、 2G/3G物理层处理模块以及 2G/3G射频处理模块等模块在 3G 网络下处理 CS域以及 PS域业务。
发明人在实现本发明的过程中, 发现现有技术至少存在以下缺点: 当现有的单卡双模终端在从一个网络重选至另一个网络时, 会存在 一段业务不可及的时间, 即在这段时间内会造成业务的中断,无论是 CS 域业务还是 PS域业务都无法进行, 从而影响了用户体验。 发明内容
本发明实施例提供一种终端选择网络方法以及双待终端, 用于提高 业务质量, 并降低终端的耗电量。
其中, 本发明实施例提供了一种终端选择网络方法, 包括: 第一网络处理模块将电路交换 CS域优先驻留到第一网络, 执行 CS 域业务;
第二网络处理模块将分组交换 PS域优先驻留到第二网络,执行 PS域 业务;
所述第一网络信号质量优于所述第二网络, 所述第二网络数据传输 速率大于所述第一网络;
当在设定的持续时间内没有 PS域业务时, 关闭所述第二网络处理模 块。
其中, 本发明实施例还提供了一种双待终端, 包括:
第一网络处理模块, 第二网络处理模块和控制模块;
所述第一网络处理模块用于将电路交换 CS域优先驻留到第一网络, 执行 CS域业务;
所述第二网络处理模块用于将分组交换 PS域优先驻留到第二网络, 执行 PS域业务;
所述第一网络信号覆盖优于所述第二网络, 所述第二网络数据传输 速率小于所述第一网络;
所述控制模块用于在设定的持续时间内没有 PS域业务时, 关闭所述 第二网络处理模块。
本发明实施例中, 通过两个模块来分别处理 CS域业务以及 PS域业 务, 并且将 CS域优先驻留到第一网络, 由于 CS域主要包括语音业务(如 拨打电话), 其对业务不可及更加敏感, 如果用户在一段时间内不能通 话, 会极大地影响用户体验, 因此, 本发明实施例优先将 CS域驻留在第 一网络(信号覆盖优于第二网络)可以改善用户对 CS域业务(如语音业 务)体验。 同时, 将 PS域业务优先驻留到数据传输速率高的第二网络, 又可以享受高速的数据业务。 同时, 本发明实施例在设定的持续时间内 没有 PS域业务时, 关闭第二网络处理模块, 可以达到节电的效果。 附图简要说明

为使本发明的目的和优点更加清楚, 下面结合附图和实施例对本发 明作进一步的详细说明。
实施例一
本发明实施例提供了一种网络重选方法, 参见图 2, 包括如下步骤: 步骤 101、 第一网络处理模块将 CS域优先驻留到第一网络, 执行 CS域业务;
步骤 102、 第二网络处理模块将 PS域优先驻留到第二网络, 执行 PS域业务;
所述第一网络信号覆盖优于所述第二网络, 所述第二网络数据传输 速率大于所述第一网络; 步骤 103、 当在设定的持续时间内没有 PS域业务时, 关闭所述第二 网络处理模块。
本发明实施例中, 将 "CS域驻留到 2G网络" 可以理解为: 终端发 起位置区更新(LAU, Location Area Update )过程附着到 2G网络; 同 时, 将 "PS域驻留到 3G网络" 可以理解为: 终端发起通用分组无线服 务技术( GPRS )附着或路由区更新 ( RAU, Route Area Update )使其附 现将 CS域驻留到 2G网络, 或者将 PS域驻留到 3G网络, 在此不再赘 述。
本发明实施例中, "关闭第二网络模块" 是指让第二网络模块不与 网络进行任何交互, 包括监听系统广播消息等, 同时关闭第二网络处理 模块对应的射频部分, 以达到节电的效果。
可以看到, 本发明实施例中, 通过两个模块来分别处理 CS域业务 以及 PS域业务, 并且将 CS域优先驻留到第一网络, 由于 CS域主要包 括语音业务(如拨打电话), 其对业务不可及更加敏感, 如果用户在一 段时间内不能通话, 会极大地影响用户体验, 因此, 本发明实施例优先 将 CS域驻留在第一网络(该第一网络信号覆盖优于第二网络)可以不 需要经常重选网络, 在从而改善用户对 CS域业务(如语音业务) 的体 验。 同时, 将 PS域业务优先驻留到数据传输速率高的第二网络, 又可 以享受高速的数据业务。
此外,发明人在实现本发明的过程中考虑到了这么一种场景: PS域 业务在很多情况下并不总是在执行,例如,有些用户虽然使用双模终端, 但可能只需要打电话、 发短信之类的 CS域业务, 而并不需要上网等 PS 域业务; 或者, 很多用户在晚上睡觉时, 一般也不需要进行 PS域业务。 基于上述场景的考虑, 本发明实施例在设定的持续时间内没有 PS域业 务时, 关闭第二网络处理模块, 以达到节电的效果。 其中, "设定的持 续时间" 并不固定, 本领域技术人员可以结合实际情况(如针对不同用 户、 不同使用习惯)来设定合适的值, 或者可以由用户来进行配置选择 (如在终端设置界面中加入一个选择 "持续时间" 的选项)。
上述第一网络可以是 2G网络(如 GSM网络), 当第一网络为 2G 网络时, 第二网络可以是 3G或 4G网络(如 WCDMA、 TD-SCDMA或 LTE等网络); 或者, 上述第一网络也可以是 3G网络, 则第二网络可以 是 4G网络(如 LTE网络)或者未来出现的新一代网络, 如果该新一代 网络也支持 PS、 CS域业务并且也存在信号覆盖相比于现有网络较差的 问题, 则也可以应用本发明实施例中的方案进行解决, 以提高业务质量 以及取得节电的效果。
进一步地, 本发明实施例中, 还可以包括以下两个方面的处理:
1 )在关闭第二网络模块后又有 PS域业务发起时的处理, 以及
2 ) 满足 "在预设的条件下进行 RAU" 条件时的处理;
这两方面都可以单独与上述步骤 101-103提到的方案进行组合, 为 了达到更好的效果, 实际应用中可以同时包含这两种处理。
具体的:
针对第 1 )种情形 ,如果在第二网络模块关闭后又有 PS域业务发起, 则在 PS域业务发起后启动第二网络处理模块;
判断第二网络处理模块是否搜索到满足驻留要求的第二网络小区, 如果是, 在第二网络路由区发生变化时, 触发第二网络处理模块发起 RAU过程、 将 PS域驻留到搜索到的第二网络小区、 并执行 PS域业务, 在第二网络路由区未发生变化时, 触发第二网络处理模块执行 PS域业 务。
当判断所述第二网络处理模块没有搜索到满足驻留要求的第二网 络小区时,触发第一网络处理模块将 PS域驻留到当前 CS域业务驻留的 第一网络小区、 并执行 PS域业务。
针对第 2 )种情形,本发明实施例在满足预设的进行 RAU过程的条 件时, 启动第二网络处理模块; 其中, "预设的进行 RAU过程的条件" 包括: 预设的周期性 RAU定时器超时, 或者第一网络处理模块判定第 一网络位置区发生变化时发起 LAU过程。
判断第二网络处理模块是否搜索到满足驻留要求的第二网络小区, 如果是, 在第二网络路由区发生变化或者预设的进行 RAU过程的条件 为周期性 RAU定时器超时且满足该条件时, 触发第二网络处理模块进 行 RAU过程、 并将 PS域驻留到搜索到的第二网络小区, 然后关闭第二 网络处理模块, 在第二网络路由区未发生变化并且预设的进行 RAU过 程的条件为周期性 RAU定时器超时且不满足该条件时, 关闭第二网络 处理模块。
当判断第二网络处理模块没有搜索到满足驻留要求的第二网络小 区,触发第一网络处理模块将 PS域驻留到当前 CS域业务驻留的第一网 络小区, 关闭第二网络
在第 2 )种场景中, 通过与网络侧进行定期交互, 可以确保终端不 被网络分离; 同时尽可能地保持了路由区信息的准确性
在上述两种处理情形中提到的:
"所述第二网络路由区发生变化" 具体为: 搜索到的第二网络小区 与第二网络处理模块关闭前 PS域驻留的第二网络小区所在的路由区不 一致; 以及,
"所述第二网络路由区未发生变化" 具体为: 搜索到的第二网络小 区与第二网络处理模块关闭前 PS域驻留的第二网络小区所在的路由区 一致。 在上述两种处理情形中提到的 "所述第二网络处理模块进行的搜 索", 是基于第一网络小区配置的第二网络邻区列表进行的; 其中, 所述启动第二网络处理模块之前进一步包括:
触发所述第一网络处理模块检测所述双待终端是否移动到未配置 第二网络邻区的第一网络小区, 如果是, 将 PS域驻留到当前双待终端 所在的第一网络小区, 并结束流程; 否则, 继续执行所述启动第二网络 处理模块的步骤。
本发明实施例中, 当所述第一网络为 GSM 网络, 所述第二网络为 3G网络时, 所述在设定的持续时间内没有 PS域业务包括:
PS域驻留或第二网络路由区更新后,在设定持续时间内没有分组数 据协议 PDP激活过程;
或者, 在 PDP去激活后, 在设定持续时间内没有 PDP激活过程。 需要说明的是,本发明实施例虽然只给出了 GSM网络以及 3G网络 下如何判定有无数据业务的方法, 但本领域技术人员可以根据本发明实 施例并结合其他网络(如 4G或者未来新出现的各种网络)数据业务中 的报文、 协议的特征来判断有无数据业务。 实施例二
本发明实施例基于实施例一, 以第一网络为 GSM 网络, 第二网络 为 TD-SCDMA (以下筒称 TD )网络为例来对本发明方案进行具体说明。
本发明实施例中, 双模终端包括两个独立的 GSM处理模块(第一 网络处理模块 )以及 TD处理模块(第二网络处理模块 ),需要说明的是, 这里 GSM处理模块或者 TD处理模块主要用于表示两个分别执行 GSM 以及 TD相关协议的模块, 这里的 "独立" 仅指在主要处理功能(在协 议层对两种业务的处理)上的独立, 可以理解的是, 实际当中, 两个模 块并非完全 "独立", 两个模块之间也可以通过一些接口或者中间单元 来完成某些信息的传送或者共享。
参见图 3, 本发明实施例包括如下步骤:
步骤 201、 GSM处理模块将 CS域优先驻留到 GSM网络, 执行 CS 域业务;
步骤 202、 TD处理模块将 PS域优先驻留到 TD网络,执行 PS域业 务;
这两个步骤执行顺序在这里并不限定, 在开机或者重启时都可以根 据一定策略来启动两个模块完成上述两个步骤, 使之在正常工作状态下 用两个模块同时执行两种业务,即实现 PS域与 CS域在两个网络的双驻 留, 因此, 可以将这种驻留在两个网络的终端称为 "双模双待终端"。
步骤 203、 判断是否在设定的持续时间内未检测到分组数据协议 ( PDP, Packet Data Protocol )上下文, 如果是, 则执行步骤 204, 否则 继续执行步骤 203。
由于现有 3G网络不支持网络激活功能, 业务只能从终端发起, 因 此没有分组数据协议(PDP, Packet Data Protocol )上下文就意味没有 PS域业务,不需要监听 PS寻呼;基于 TD-SCDMA网络(属于 3G网络) 的特点,通过检测是否有 PDP上下文,可以间接检测是否有 PS域业务。
在具体实现时, 可以设置一个定时器, 在 PS域附着或 TD-SCDMA 网络路由区更新后,启动该定时器,在超时时间内没有 PDP激活过程时, 就判定在设定的持续时间内未检测到 PDP上下文,此时可以关闭 TD处 理模块; 或者, 在 PDP去激活后, 启动该定时器, 在超时时间内没有 PDP激活过程时,就判定在设定的持续时间内未检测到 PDP上下文。无 论哪种判定方式, 只要激活 PDP上下文, 就关闭上述定时器。
步骤 204: 关闭 TD处理模块。 经过上述步骤 201~步骤 204, 可以避免 CS域经常重选网络, 改善 用户体验, 同时降低双模双待终端的耗电量。
图 4为本发明实施例中 TD处理模块关闭时执行 PS域业务的流程 图, 该流程包括:
步骤 211: 在 PS域业务发起后启动 TD处理模块。
PS域业务可以由应用程序发起, 当有应用程序发起 PS域业务后, 通过控制单元启动 TD处理模块;
步骤 212: 判断 TD处理模块是否搜索到满足驻留要求的 TD小区, 如果是, 执行步骤 213, 否则执行步骤 216。
本步骤中, TD处理模块将在 GSM小区配置的 TD邻区列表中进行 搜索。 TD处理模块在判定搜索到的 TD小区的信号质量是否满足驻留要 求时, 需要综合考虑搜索到的 TD小区的信号质量和小区状态等多个因 素。
步骤 213: 判断 TD路由区是否发生变化, 如果是, 执行步骤 214, 否则执行步骤 215。
本步骤中,如果搜索到的 TD小区与 TD处理模块关闭前 PS域驻留 的 TD小区所在的路由区不同, 则说明 TD路由区发生变化, 否则说明 TD路由区未发生变化。
步骤 214: 触发 TD处理模块发起 RAU过程、 将 PS域驻留到搜索 到的 TD小区、 并执行 PS域业务, 结束流程。
步骤 215: 触发 TD处理模块执行 PS域业务, 结束流程。
步骤 216: 触发 GSM处理模块将 PS域驻留到当前 CS域业务驻留 的 GSM小区、 并执行 PS域业务, 结束流程。
可以看出在上述步骤 211~步骤 216描述的执行 PS域业务的过程中, 如果 TD路由区发生变化, 则需要 TD处理模块通过 RAU过程进行 TD 路由区更新, 延长了执行 PS域业务所需的时间。 为了进一步提高用户 体验, 在执行 PS域业务过程中尽量减少进行 RAU过程的可能性, 从而 缩短执行 PS域业务的时间。
本应用实例中还可以在关闭 TD处理模块后,按照预设的进行 RAU 过程的条件, 周期性或者不定期的进行 RAU过程。 图 4为本发明实施 例中 TD处理模块关闭时进行 RAU过程的流程图, 该流程包括:
步骤 221: 在满足预设的进行 RAU过程的条件时, 启动 TD处理模 块。
本步骤中,预设的进行 RAU过程的条件可以为:预设的周期性 RAU 定时器超时,或者 GSM处理模块判定 GSM位置区发生变化时发起 LAU 过程。
步骤 222: 判断 TD处理模块是否搜索到满足驻留要求的 TD小区, 如果是, 执行步骤 223, 否则执行步骤 226。
本步骤中, TD处理模块将在 GSM小区配置的 TD邻区列表中搜索 符合驻留要求的 TD小区。 搜索的方式与步骤 222中相同。
步骤 223: 判断 TD路由区是否发生变化或者步骤 221 中满足的条 件是否是周期性 RAU定时器超时, 如果是, 执行步骤 224, 否则执行步 骤 225。
即, 在步骤 221 中, 如果满足 "周期性 RAU定时器超时" 这个预 设的条件时,执行到步骤 223后,再接着执行步骤 224; 如果在步骤 221 中, 如果满足预设的条件是指 "GSM处理模块判定 GSM位置区发生变 化时发起位置区更新过程",则在步骤 223中还需要判断 TD路由区是否 发生变化。
步骤 224: 触发 TD处理模块进行 RAU过程、 并将 PS域驻留到搜 索到的 TD小区, 然后执行步骤 225。 步骤 225: 触发 GSM处理模块将 PS域驻留到当前 CS域业务驻留 的 GSM小区。
步骤 225: 关闭 TD处理模块。
需要说明的是, 图 5所示的流程中, 虽然已经执行了步骤 223以及 步骤 224用于判断 TD路由区是否发生变化,并在发生变化时进行 RAU; 但是,如果在关闭 TD处理模块后又有 PS域业务发起时,则仍然需要执 行判断 TD区是否发生变化以及在发生变化时进行 RAU (参见图 4中步 骤 213、 214 )。 这是因为在 TD模块关闭的前提下, 在路由区发生变化 时仍然存在不满足预设的进行 RAU过程的场景, TD的路由区信息不一 定得到及时更新。 因此在 PS域业务发起时, 图 4中所示步骤 213中判 断 TD路由区是否发生变化,所示步骤 214中如果发生变化则发起 RAU 过程还是非常必要的。
在执行 PS域业务过程中, TD处理模块均需在 GSM小区配置的 TD 邻区列表中进行搜索, 如果双待终端在 TD处理模块关闭期间移动到没 有配置 TD邻区列表的 GSM小区,则 TD处理模块再次启动后将不可能 搜索到符合驻留要求的 TD小区, 在这种情况下, 为了进一步提高节电 效果, 避免 TD处理模块执行不必要的操作, 在步骤 212步骤之前, 可 以先触发 GSM处理模块检测双待终端是否移动到未配置 TD邻区列表 的 GSM小区, 如果是, 则不启动 TD处理模块, 而直接将 PS域驻留到 当前 GSM小区、 执行 PS域业务, 并结束流程, 否则再继续执行步骤 212。 在步骤 222之前, 可以先触发 GSM处理模块检测双待终端是否移 动到未配置 TD邻区列表的 GSM小区,如果是,则不启动 TD处理模块, 而直接将 PS域驻留到当前 CS域业务驻留的 GSM小区, 并结束流程, 否则再继续执行步骤 222。 实施例三
本发明实施例还提供一种双模双待终端 30, 在上述实施例一、 二中 已经对该终端进行了筒单介绍, 为了更清楚地对该终端进行介绍, 下面 通过本发明实施例来进行具体说明。
参见图 6, 该终端 30包括:
第一网络处理模块 31 , 第二网络处理模块 32和控制模块 33;
所述第一网络处理模块 31用于将 CS域优先驻留到第一网络,执行 CS域业务;
所述第二网络处理模块 32用于将 PS域优先驻留到第二网络, 执行 PS域业务;
所述第一网络信号质量优于所述第二网络, 所述第二网络数据传输 速率小于所述第一网络;
所述控制模块 33用于在设定的持续时间内没有 PS域业务时, 关闭 所述第二网络处理模块。
由于终端在进行信号处理时, 涉及到多个方面, 例如协议层、 物理 层以及射频处理等层面, 其中, 本发明实施例中的第一网络处理模块以 及第二网络处理模块为协议层的处理, 为了说明方便, 下面只针对协议 层方面进行说明, 而不对物理层、 射频处理等方面进行详细说明。
本发明实施例中, 控制单元可以为在协议层之外的一个单元, 该控 制单元可以与第二网络处理模块进行信号交互, 例如, 用于在第二网络 处理模块在持续时间内有无 PS域业务时, 关闭第二网络处理模块。 其 中, 第二网络处理模块有无 PS域业务可以通过多种方法进行, 例如, 可以是第二网络处理模块定期检测自身有无 PS域业务, 并将每次结果 发送给控制模块, 由控制模块最后确认在持续有时间内有无 PS域业务, 或者, 也可以由控制模块每隔一定时间向第二网络处理模块发送触发控 制模块进行检测的命令,使得第二网络处理模块收到命令后检测有无 PS 域业务, 并将结果返回给控制模块, 最后由控制模块来确定在持续的时 间内有无 PS域业务。
基于上述实施例一、 二, 本发明实施例中, 控制模块还用于: 在 PS域业务发起后启动第二网络处理模块;
判断第二网络处理模块是否搜索到满足驻留要求的第二网络小区, 如果是, 在第二网络路由区发生变化时, 触发第二网络处理模块发起
RAU过程、 将 PS域驻留到搜索到的第二网络小区、 并执行 PS域业务, 在第二网络路由区未发生变化时, 触发第二网络处理模块执行 PS域业 务。
当判断所述第二网络处理模块没有搜索到满足驻留要求的第二网 络小区时,触发第一网络处理模块将 PS域驻留到当前 CS域业务驻留的 第一网络小区、 并执行 PS域业务。
此外, 控制模块还用于:
在满足预设的进行 RAU过程的条件时, 启动第二网络处理模块; 其中, 预设的进行 RAU过程的条件包括: 预设的周期性 RAU定时器超 时, 或者第一网络处理模块判定第一网络位置区发生变化时发起 LAU 过程。
判断第二网络处理模块是否搜索到满足驻留要求的第二网络小区, 如果是, 在第二网络路由区发生变化或者预设的进行 RAU过程的条件 为周期性 RAU定时器超时且满足该条件时, 触发第二网络处理模块进 行 RAU过程、 并将 PS域驻留到搜索到的第二网络小区, 然后关闭第二 网络处理模块, 在第二网络路由区未发生变化并且预设的进行 RAU过 程的条件为周期性 RAU定时器超时且不满足该条件时, 关闭第二网络 处理模块。 当判断第二网络处理模块没有搜索到满足驻留要求的第二网络小 区,触发第一网络处理模块将 PS域驻留到当前 CS域业务驻留的第一网 络小区, 关闭第二网络处理模块。
其中,上述说明中提到的所述第二网络处理模块进行的搜索,如 "判 断第二网络处理模块是否搜索到满足驻留要求的第二网络小区", 是基 于第一网络小区配置的第二网络邻区列表进行的; 在启动第二网络处理 模块之前进一步包括:
触发所述第一网络处理模块检测所述双待终端是否移动到未配置 第二网络邻区的第一网络小区, 如果是, 将 PS域驻留到当前双待终端 所在的第一网络小区, 并结束流程; 否则, 继续执行所述启动第二网络 处理模块的步骤。
当所述第一网络为 GSM网络,所述第二网络为 3G网络时,所述控 制模块具体用于:
在 PS域附着或第二网络路由区更新后, 在设定持续时间内没有分 组数据协议 PDP激活过程时, 关闭所述第二网络处理模块,;
或者, 在 PDP去激活后, 在设定持续时间内没有 PDP激活过程时 关闭所述第二网络处理模块。
通过本发明实施例, 可以完成实施例一、 二中的方法流程, 用以提 高业务质量, 并降低手机电量的消耗。 实施例四
更具体的, 基于实施例三, 本发明实施例中提供了一种单卡双待终 端, 参见图 7, 与现有技术单卡双模终端不同之处在于, 本发明实施例 单卡双待终端(以 2G/3G单卡双待终端为例)包括 2G处理单元 41以及 3G处理单元 42两个独立的处理单元,用于分别处理 2G业务以及 3G业 务。 具体的, 参见图 8, 为 2G处理单元以及 3G处理单元的具体结构示 意图, 其中, 2G处理单元包括 2G协议栈处理模块 411 , 2G物理层处理 模块 412, 2G射频处理模块 413以及 2G天线 414; 3G处理单元包括 3G 协议栈处理模块 421 , 3G物理层处理模块 422, 3G射频处理模块 423 以及 3G天线 424。

可以将图 8中的 2G协议栈处理模块对应于图 6中的第一网络处理 模块, 将 3G协议栈处理模块对应于图 6中的第二网络处理模块, 将业 务适配模块对应于图 6 中的控制模块; 可以通过本发明实施例中的 2G 协议栈处理模块、 3G协议栈处理模块以及业务适配模块来完成实施例 一、 二中的相关方法流程, 在此不再赘述。

事实上, 本发明实施也可以应用于多模双待, 即手机可以设置多个 处理模块, 在多个网络中根据网络的信号质量、 数据传输数率等方面的 考虑来将 CS域以及 PS域优先驻留到相应的网络,其具体处理方法以及 硬件结构可以参考上面双待终端处理方法与硬件结构, 在此也不再赘 述。
