为了解决上述问题, 双卡双待的手机应运而生。 为了实现双卡双待的 功能, 目前有一种解决方案是: 采用一块基带芯片加两颗射频芯片 (即两 路射频芯片共用射频 -基带接口) 的方式, 这种方案相比主流的两套基带加 两套射频的方案, 无论是在成本、 稳定性、 功耗及手机尺寸上都有明显的 优势。

本发明实施例中: 在使用一套基带加两套射频且基带-射频接口共用的 平台上, 通过在射频 -基带接口上添加开关切换模块, 让两路独立射频通道 的射频模块分别循环使用, 释放基带资源, 避免一路射频通道独占射频-基 带接口, 以实现手机的双卡双待双通, 提高基带资源利用率, 提升用户体 验及双卡手机的实用性。
本发明实施例的终端具体指具有双卡功能的手机等移动终端, 以下各 实施例均以手机为例进行说明。
如图 1 所示, 本发明一实施例提出一种实现移动终端双卡双待双通的 方法, 包括:
步骤 S101, 共用基带射频接口建立两条射频通道;
设定其中一条射频通道为第一射频通道(RF1-基带通道), 另一射频通 道为第二射频通道(RF2-基带通道), 两通道分别对应第一终端卡和第二终 端卡。
上述终端卡具体可以采用身份识别模块 (SIM, Subscriber Identity Module )卡, 即第一 SIM卡和第二 SIM卡。 两 SIM卡的通讯网络包括但 不限于以下几种方式: 码分多址( CDMA, Code Division Multiple Access )、 宽带码分多址(WCDMA, Wideband Code Division Multiple Access ), 全球 移动通信系统( GSM, Global System for Mobile Communications )及时分同 步码分多址( TD-SCDMA, Time Division-Synchronous Code Division Multiple Access λ
本实施例使用一套基带加两套射频通道且基带-射频接口共用的平台 上, 实现手机双卡双待双通的功能。
步骤 S102, 通过开关切换模块以预定周期在所述两条射频通道间循环 切换, 进行移动终端的双卡双待双通。
为了实现手机双卡双待双通的功能, 在基带与两路射频通道的接口信 号上添加开关切换模块(此开关切换模块可以是模拟开关, 但不局限于模 拟开关), 不断地在 RF1-基带与 RF2-基带这两条通路间切换, 复用基带, 防止一^ ^通话时独占基带, 从而实现双卡双待双通。
具体地, 本实施例方法运行环境涉及的系统框架如图 2所示, 其包括: RF1模块、 RF2模块; 开关切换模块; 开关控制模块; SIM卡 1模块, SIM 卡 2模块; 卡 1协议栈模块, 卡 2协议栈模块; 基带处理模块; 各模块功 能描述如下:
( 1 ) RF1模块, RF2模块。 即前述两路射频芯片及相关射频通路。 用 于射频信号的收发, 以及与基带间的数据传输。 RF1模块对应 SIM卡 1, RF2模块对应 SIM卡 2;
( 2 )开关切换模块。 用于 RF1-基带通道(RF1模块与基带芯片通路)、 RF2-基带通道(RF2模块与基带芯片通路) 间的循环切换;
( 3 )开关控制模块。 即上述开关切换模块的驱动控制部分, 由软件处 理。 该模块有两部分作用, 首先用于开关切换模块的状态控制及驱动; 其 次, 同步通知基带处理模块, 具体的某一时刻是哪张卡的通路被打开, 基 带处理模块此刻应该处理哪张卡的数据等;
( 4 ) SIM卡 1模块, SIM卡 2模块。为各自独立的身份识别模块, SIM 卡 1模块对应 SIM卡 1, SIM卡 2模块对应 SIM卡 2;
( 5 )卡 1协议栈模块,卡 2协议栈模块。 为各自独立的协议处理模块, 用于各自协议处理等。 卡 1协议栈模块对应 SIM卡 1, 卡 2协议栈模块对 应 SIM卡 2;
( 6 )基带处理模块。 负责总体的收发请求处理, 数据传输、 处理及相 关控制、 监测等。 开关控制模块在驱动开关切换模块进行切换时, 同时也 通知基带处理模块:
当 RF1-基带通道打开时, 要求基带处理模块传输、 处理 SIM卡 1的收 发请求及相关数据;
当 RF2-基带通道打开时, 要求基带处理模传输、 处理 SIM卡 2的收发 请求及相关数据。
其中, 开关控制模块、 卡 1协议栈模块、 卡 2协议栈模块以及基带处 理模块都包含在手机基带芯片内。
首先, 开关切换模块会在开关控制模块的驱动下, 不断地在 RF1-基带 /RF2-基带这两条通道间循环切换, 切换时间可调, 即 RF1-基带的导通、 关 断时间 (对应 RF2-基带的关断、 导通时间)可视情况进行调整。
这样 SIM卡 1的收发请求及数据等会在 RF1-基带打开时, 由基带处理 模块及卡 1协议栈模块共同进行相关处理; SIM卡 2的收发请求及数据, 在 RF2-基带通道打开时, 由基带处理模块及卡 2协议栈模块共同进行相关 处理。 保证 SIM卡 1和 SIM卡 2的来电、 拨号、 通话等均有机会给基带进 行处理, 不会出现其中一路来电时独占射频 -基带接口, 而导致另一路无法 接听或拨打电话, 实现手机的双卡双待双通。
具体地, 如图 3所示, 对应手机双卡双待的情况, 上述步骤 S102中, 通过开关切换模块以预定周期在所述两条射频通道间循环切换, 进行移动 终端的双卡双待的步骤包括:
步骤 S1021 ,根据预定的切换周期判断当前切换至第一射频通道还是第 二射频通道; 若切换至第一射频通道, 则进入步骤 S1022; 否则, 进入步骤 S1024;
步骤 S1022 ,控制开关切换模块导通第一射频通道,关断第二射频通道; 步骤 S1023 ,通知基带处理模块监测并处理所述第一终端卡经第一射频 通道发送的收发请求及相关数据; 所述第一终端卡处于待机状态, 第二终 端卡处于等待状态; 本步骤执行完后返回步骤 S1021。
步骤 S1024,控制开关切换模块关断第一射频通道,导通第二射频通道; 步骤 S1025 ,通知基带处理模块监测并处理所述第二终端卡经第二射频 通道发送的收发请求及相关数据; 所述第二终端卡处于待机状态, 第一终 端卡处于等待状态; 本步骤执行完后返回步骤 S1021。
以手机为例, 在本实施例中, 开关切换模块在开关控制模块的驱动下, 不断地在 RF1-基带、 RF2-基带这两条通道间循环切换, 切换时间可调, 即
RF1-基带通道的导通、 关断时间 (对应 RF2-基带通道的关断、 导通时间) 可视情况进行调整。
对应 RF1-基带通道导通阶段:
首先, 在开关控制模块驱动开关切换模块, 使 RF1-基带通道打开时, 开关控制模块会同步通知基带处理模块,要求基带处理模块监测、处理 SIM 卡 1的收发请求及相关数据。 于是, 这个阶段 SIM卡 1处于待机状态, 此 时 SIM卡 2处于等待状态;
对应 RF2-基带通道导通阶段:
当切换周期到来时, 开关控制模块驱动开关切换模块, 切换到 RF2-基 带通路打开, 同时开关控制模块通知基带处理模块, 要求基带处理模块监 测、 处理 SIM卡 2的收发请求及相关数据。 于是, 此阶段 SIM卡 2处于待 机状态, SIM卡 1则转到等待状态; 后续, 第二次 RF1-基带通道导通阶段:
到开关切换模块第二次切换到 RF1-基带通路打开时, SIM卡 1继续占 用基带处理模块, 则 SIM卡 1处于待机状态;
第二次 RF2-基带导通阶段:
直到下一次状态切换到来, RF2-基带通路打开时, SIM卡 2处于待机 状态。
依据上述原理, 开关切换模块不断地在 RF1-基带、 RF2-基带这两条通 路间循环切换, 实现 SIM卡 1和 SIM卡 2的双卡双待。
如图 4所示, 对应手机双卡双通的情况, 上述步骤 S102中, 通过开关 切换模块以预定周期在所述两条射频通道间循环切换, 进行移动终端的双 卡双通的步骤包括:
步骤 S1021 ,根据预定的切换周期判断当前切换至第一射频通道还是第 二射频通道; 若切换至第一射频通道, 则进入步骤 S1022; 否则, 进入步骤 S1024;
步骤 S1022 ,控制开关切换模块导通第一射频通道,关断第二射频通道; 步骤 S1023 ,通知基带处理模块监测、传输并处理所述第一终端卡经第 一射频通道发送的收发请求及相关数据; 所述第一终端卡处于待机状态, 第二终端卡处于等待状态;
步骤 S1026, 当所述第一终端卡有来电或拨号时, 所述第一终端卡的通 话请求由基带处理模块及该第一终端卡的协议栈模块共同进行处理; 若来 电或拨号接通,第一终端卡进入通话状态;本步骤执行完后返回步骤 S1021。
步骤 S1024,控制开关切换模块关断第一射频通道,导通第二射频通道; 步骤 S1025 ,通知基带处理模块监测、传输并处理所述第二终端卡经第 二射频通道发送的收发请求及相关数据; 所述第二终端卡处于待机状态, 第一终端卡处于等待状态;
步骤 S1027 , 当所述第二终端卡有来电或拨号时, 所述第二终端卡的通 话请求由基带处理模块及该第二终端卡的协议栈模块共同进行处理; 若来 电或拨号接通, 所述第二终端卡处于通话状态; 本步骤执行完后返回步骤
S102K
对应手机双卡双通的情形, 同样道理, 开关切换模块在开关控制模块 的驱动下, 不断地在 RF1-基带、 RF2-基带这两条通路间循环切换:
RF1-基带通道打开阶段:
首先,开关切换模块在开关控制模块的驱动下,使 RF1-基带通道打开, 开关控制模块会同时通知基带处理模块, 要求基带处理模块监测、 传输、 处理 SIM卡 1的收发请求及相关数据, 此时 SIM卡 1处于待机状态;
当手机 SIM卡 1有来电时, SIM卡 1的通话请求会由基带处理模块及 卡 1协议栈模块共同进行处理。 若用户选择接通 SIM卡 1的来电, 基带处 理模块开始处理 SIM卡 1的通话数据等, 于是 SIM卡 1处于通话状态; 对应 RF2-基带通路打开阶段:
当切换周期到来时, 开关控制模块驱动开关切换模块, 切换到 RF2-基 带通道打开, 并且开关控制模块同时通知基带处理模块, 要求基带处理模 块监测、 传输、 处理 SIM卡 2的收发请求及相关数据, 此时 SIM卡 2处于 待机状态;
此时, 可以检测 SIM卡 2是否有来电或者是否有拨号, 若无来电、 无 拨号, 则 SIM卡 2维持待机状态; 若有来电或有拨号, 则可以选择进入通 话状态, 或者挂断或者选择发短消息给呼叫方 "正在电话中, 稍后回复" 等; 此阶段 SIM卡 1处于等待状态, 等待下一次切换到来;
后续, 第二次 RF1-基带通道打开阶段:
等到开关切换模块第二次切换至 RF1-基带通道打开时, SIM卡 1再次 占用基带处理模块, 基带处理模块会继续处理 SIM卡 1的通话数据;
第二次 RF2-基带通路打开阶段:
同样地,在第二次 RF2-基带通道打开时,基带处理模块会继续处理 SIM 卡 2的相关通讯数据等。
依次这样不断地循环切换下去。所以在不同的时间段, SIM卡 1和 SIM 卡 2的通话都可以得到及时、 完整的处理, 从而实现双卡双通。
由于开关控制模块驱动开关切换模块不断地在 RF1-基带、 RF2-基带这 两条通路间循环切换, 这样就避免了一张卡来电时, 该卡的射频独占射频- 基带接口, 导致另一张卡无法进行通话处理的问题出现, 从而实现了两路 射频加一颗基带, 达到双卡双待双通的目的。
本实施例通过上述方案, 使用一套基带加两套射频且基带-射频接口共 用的平台上, 通过在射频 -基带接口上添加开关切换模块, 让两路独立射频 模块分别循环使用、 释放基带处理模块, 避免一路独占射频-基带接口 (即 独占基带), 从而实现手机的双卡双待双通, 不仅提高了基带资源利用率, 而且提升了用户体验及双卡手机的实用性, 相比现有技术, 在软件处理上 更简单, 稳定性更高, 在成本上更有优势, 而且节省布局空间, 功耗更小, 发热更少。

RF1-基带通道打开阶段:
首先,开关切换模块在开关控制模块的驱动下,使 RF1-基带通道打开, 开关控制模块会同时通知基带处理模块, 要求基带处理模块监测、 传输、 处理 SIM卡 1的收发请求及相关数据, 此时 SIM卡 1处于待机状态;
当手机 SIM卡 1有来电时, SIM卡 1的通话请求会由基带处理模块及 卡 1协议栈模块共同进行处理。 若用户选择接通 SIM卡 1的来电, 基带处 理模块开始处理 SIM卡 1的通话数据等, 于是 SIM卡 1处于通话状态; 对应 RF2-基带通路打开阶段:
当切换周期到来时, 开关控制模块驱动开关切换模块, 切换到 RF2-基 带通道打开, 并且开关控制模块同时通知基带处理模块, 要求基带处理模 块监测、 传输、 处理 SIM卡 2的收发请求及相关数据, 此时 SIM卡 2处于 待机状态;
此时, 可以检测 SIM卡 2是否有来电或者是否有拨号, 若无来电、 无 拨号, 则 SIM卡 2维持待机状态; 若有来电或有拨号, 则可以选择进入通 话状态, 或者挂断或者选择发短消息给呼叫方 "正在电话中, 稍后回复" 等。 此阶段 SIM卡 1处于等待状态, 等待下一次切换到来;
后续, 第二次 RF1-基带通道打开阶段:
等到开关切换模块第二次切换至 RF1-基带通道打开时, SIM卡 1再次 占用基带处理模块, 基带处理模块会继续处理 SIM卡 1的通话数据;
第二次 RF2-基带通路打开阶段:
同样地,在第二次 RF2-基带通道打开时,基带处理模块会继续处理 SIM 卡 2的相关通讯数据等。
依次这样不断地循环切换下去。所以在不同的时间段, SIM卡 1和 SIM 卡 2的通话都可以得到及时、 完整的处理, 从而实现双卡双通。
由于开关控制模块驱动开关切换模块不断地在 RF1-基带、 RF2-基带这 两条通路间循环切换, 这样就避免了一张卡来电时, 该卡的射频独占射频- 基带接口, 导致另一张卡无法进行通话处理的问题出现, 从而实现了两路 射频加一颗基带, 达到双卡双待双通的目的。
本实施例通过上述方案, 使用一套基带加两套射频且基带-射频接口共 用的平台上, 通过在射频 -基带接口上添加开关切换模块, 让两路独立射频 模块分别循环使用、 释放基带处理模块, 避免一路独占射频-基带接口 (即 独占基带), 从而实现手机的双卡双待双通, 不仅提高了基带资源利用率, 而且提升了用户体验及双卡手机的实用性, 相比现有技术, 在软件处理上 更简单, 稳定性更高, 在成本上更有优势, 而且节省布局空间, 功耗更小, 发热更少。
以上所述仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是利用本发明说明书及附图内容所作的等效结构或流程变换, 或直接或 间接运用在其它相关的技术领域, 均同理包括在本发明的专利保护范围内。 工业实用性
