Description

多卡多待终端及其同步方法和装置 技术领域
本发明涉及移动通信终端,特别是涉及一种多卡多待终端及其同步方法和 装置。
背景技术
随着通讯技术的飞速发展,人与人之间的信息交流也更频繁, 一个移动通 信终端(例如手机、 车载移动终端等) 已无法满足人们的需求, 尤其是从事销 售、 管理等类工作的人, 有时需要两三个甚至更多终端才能勉强满足需要。 而 携带这么多终端很是不便, 因此, 市场上出现了多卡终端。 这种终端使用户只 需要一个载体, 但可安装多个终端卡( SIM卡或 UIM卡或 USIM卡 ), 相比携 带多个终端明显方便了很多。
如果用户需要在一个终端使用多个号码, 则一般可以采取以下方案:
1. 多卡单待系统: 虽然能够同时接两张或两张以上终端卡, 但实际上当 前可用的只有一张, 由硬件电路来实现多张卡的切换, 一般在开机时选择, 因 为协议栈的影响,一般在工作状态中不能实现多张卡的动态切换,如果切换一 般需要重新启动手机系统(主要是启动手机协议栈 /上层软件等等)。
2. 多卡多待系统: 克月良了以往多卡单待系统的局限性, 其可以实现多张 终端卡的同时待机, 可以同时接收多张终端卡的被叫,类似同时具备多个单卡 终端, 显然实用性得到大大提高。
早期的多卡多待终端, 实际上是拥有多套系统(一般为两套),每套系统 都包括各自的射频、基带、 协议栈, 采用多套系统的终端确实可以完成多个号 码的真正同时待机及通话, 也可以称之为多卡多待多通系统。 但是, 这样的多 卡终端由于采用了多套系统,成本增加了^艮多;并且相应的耗电量也大大增加; 而且终端的体积也随之增大, 使用起来不够方便; 对于射频模块而言, 因为存 在同频干扰问题,一般是将一个射频模块设计在终端顶端, 另外一个设计在终 端末端, 以尽量减少干扰, 两根天线之间的距离一般必须大于 100毫米。
后期出现的多卡多待终端可称为多卡多待单通系统,其相比上面的多套系 统而言, 只使用了一套通讯模块, 因为上层协议栈需要协同工作, 所以原先的 多套独立运行的协议栈需要密切整合, 实际操作虽然复杂了,但可以实现多卡 多待效果。
目前的多卡多待终端, 在开机时, 多张终端卡各自独立搜网并驻留小区, 所以多张终端卡会同时驻留在多个不同的小区上。
而多张终端卡驻留在多个不同的小区,或者即使多张终端卡驻留的小区是 相同的, 多张终端卡的邻区测量处理和重选行为也是独立的, 可能部分终端卡 重选到新小区, 而另一部分终端卡并没有重选, 所以多张终端卡仍会同时驻留 在多个不同的小区上。
但是, 对于多卡多待单通系统, 由于只有一套通讯模块, 此时针对每个小 区的寻呼接收和邻区测量只能采用分时的方式来轮流切换,多张终端卡分别驻 留在不同的小区上其寻呼接收效率通常与同时待机的卡数成反比,对邻区的测 量机会会随着同时待机的卡数的增加而减少。
对于功耗来说, 由于每张终端卡各自驻留在不同的小区上, 需要分时轮流 在不同的小区上进行寻呼接收和邻区测量,终端的空闲时间就会比单待终端少 4艮多, 相应地功耗就会比较高。
发明内容
本发明解决的问题是现有的多卡多待终端的寻呼接收和邻区测量的效率 低, 且终端功耗较高。
为解决上述问题, 本发明实施方式提供一种多卡多待终端的同步方法, 包 括: 在第一终端卡成功驻留小区后,控制第二终端卡驻留在所述第一终端卡成 功驻留的小区,所述第二终端卡为适合与所述第一终端卡驻留相同小区的终端 卡。

可选的, 所述同步方法包括: 所述第一终端卡根据邻区测量结果判断是否 有符合重选条件的第二小区, 若是, 则所述第一终端卡重选所述第二小区; 在 所述第一终端卡成功驻留所述第二小区后,控制所述第二终端卡重选到所述第 二小区。
可选的, 在所述第一终端卡驻留小区的过程中,储存所述第一终端卡接收 到的系统消息;所述控制第二终端卡驻留在所述第一终端卡成功驻留的小区包 括: 控制所述第二终端卡读取所述储存的系统消息。
为解决上述问题, 本发明实施方式还提供一种多卡多待终端的同步装置, 包括:
判断单元, 用于确定第一终端卡, 并判断其他终端卡中是否存在第二终端 卡, 所述第二终端卡为适合与所述第一终端卡驻留相同小区的终端卡;

可选的, 所述控制单元包括: 重选控制单元, 用于在所述第一终端卡重选 并成功驻留第二小区后,且所述判断单元的判断结果为是时,控制所述第二终 端卡重选到所述第二小区。
可选的, 所述控制单元还包括: 开机控制单元, 用于在所述第一终端卡开 机搜网并成功驻留第一小区后,且所述判断单元的判断结果为是时,控制所述 第二终端卡驻留在所述第一小区。
可选的, 所述同步装置还包括: 储存单元, 用于在所述第一终端卡驻留小 区的过程中,储存所述第一终端卡接收到的系统消息; 所述控制单元还用于控 制所述第二终端卡在驻留所述第一终端卡成功驻留的小区的过程中,读取所述 储存的系统消息。 第二终端卡驻留在其他小区。
本发明实施方式还提供一种包括上述同步装置的多卡多待终端。
可选的, 所述多卡多待终端包括基带处理芯片和射频芯片, 所述同步装置 嵌入于所述基带处理芯片。
可选的, 所述多卡多待终端为双卡双待终端。
上述技术方案在判断得到多张终端卡可以驻留相同小区时强制这些终端 卡驻留在相同的小区, 与现有技术相比, 上述技术方案具有以下优点:
可以同时接收驻留在相同小区的终端卡的寻呼消息,并分别通知到各张终 端卡,相比于现有采用分时方式来轮流切换每个小区的寻呼接收而言,寻呼接 收效率更高, 也避免了寻呼丢失; 并且, 由于无需分时轮流在不同的小区上进 行寻呼接收, 终端的空闲时间也就增加, 相应地功耗也较低。
驻留在相同小区的多张终端卡可以共用邻区测量信息,物理层统一对该小 区的邻区进行测量,邻区测量结果可以只报告给第一终端卡,相比于现有采用 分时方式来轮流切换每个小区的邻区测量而言, 测量效率更高; 并且, 由于无 需分时轮流在不同的小区上进行邻区测量, 终端的空闲时间也就增加,相应地 功耗也较低。
第一终端卡驻留小区后存储接收到的小区系统消息,后续驻留相同小区的 终端卡可以直接读取存储的系统消息, 而不需要重新接收系统消息,从而显著 缩短了终端卡驻留小区的时间

所述第一终端卡也可以为预先指定的终端卡,即开机时指定多张终端卡中 的一张终端卡进行搜网和小区驻留。

PLMN区分了不同的运营商或者同一运营商的不同模式的网络。例如, 可 以用来区分中国移动和中国联通, 也可以区分中国移动的 TD-SCDMA ( Time Division-Synchronous Code Division Multiple Access, 时分同步的码分多址 ) 网 络和 GSM网络, 或者区分中国联通的 WCDMA ( Wideband CDMA, 宽带码 分多址)或其 GSM网络。 事实上, 现存的手机, 就是通过识别 PLMN, 而在 手机屏幕上显示 "2G"或 "3G"标识的。 2G(第二代)指的就是 GSM、 CDMA- IX 网络, 而 TD-SCDMA、 WCDMA等即为 3G (第三代) 网络。 TD-SCDMA和 WCDMA网络演进网络, 即为长期演进(LTE, Long Term Evolution ) 系统。
按 PLMN的关系来分类, 还可以分为 HPLMN ( Home Public Land Mobile Network,本地公用陆地移动网络,或称为归属 PLMN ), EHPLMN ( Equivalent Home PLMN, 对等归属 PLMN ), EPLMN ( Equivalent PLMN, 对等 PLMN )、 RPLMN ( Registered Public Land Mobile Network , 注册 PLMN )等。 这主要 用来区分终端卡和 PLMN之间的关系。例如,中国移动的 TD-SCDMA的 PLMN 是其 GSM网络的 EPLMN, 可以筒单的认为, 手机驻留在中国移动的 GSM和 TD-SCDMA, 是等效的, 即计费 (拨打电话、 发送短信等业务)、 允许的业务 等的收费政策是一致的。 对于中国移动发放的 SIM或 USIM卡, 中国移动的 GSM网络就是其 HPLMN, TD-SCDMA则为 EHPLMN。 RPLMN就是上次注 册成功的 PLMN。 卡双待手机包括终端卡 1和终端卡 2。 实施例 1
本实施例的多卡多待终端的同步方法如图 1所示, 包括:
步骤 S1 , 第一终端卡开机搜网并成功驻留第一小区;
步骤 S2, 控制第二终端卡驻留在所述第一小区;
步骤 S3, 所述第一终端卡根据邻区测量结果判断是否有符合重选条件的 第二小区, 若是, 则所述第一终端卡重选所述第二小区;
步骤 S4, 在所述第一终端卡成功驻留所述第二小区后, 控制所述第二终 端卡重选到所述第二小区。
其中, 步骤 S1和 S2为开机过程的终端卡的小区同步, 步骤 S3和 S4为 重选过程的终端卡的小区同步。
图 2为本实施例的多卡多待终端的同步方法的开机过程流程图, 具体地, 即为双卡双待手机在开机过程中双卡小区同步的详细流程图。
首先执行步骤 S11 , 开机, 终端卡 1搜网。 本实施例中, 预先指定终端卡 1在开机时搜网, 这样对于多卡多待单通系统, 由于只有一套通讯模块, 无需 采用分时的方式来轮流切换 2张卡的搜网, 因此搜网过程更快。
搜网过程包括:
( a )测量手机支持频段内的所有频点的接收信号场强指示( RSSI )。 具体 地, 依据手机支持的网络制式扫描频段内的所有频点, 测量各频点的 RSSI。
( b )判断是否有频点需要进行小区搜索, 若有则进行(c ), 若没有则搜 网过程结束。 如果频点的 RSSI大于预设门限值(例如 -108dbm ), 则该频点需 要进行小区搜索; 否则, 没有适合驻留的小区, 搜网失败。
( c )根据 RSSI从高到低的顺序选择一个频点进行小区搜索,如果搜索成 功则进行(d ), 如果搜索失败则继续选择一个频点进行小区搜索。 具体地, 将 需要进行小区搜索的频点按照 RSSI从高到低排序, 首先选择信号强度最高的 频点进行小区搜索, 手机接收到小区的同步信息 ( GSM网络为同步信道 SCH 传输的信息, TD-SCDMA网络为主公共控制物理信道 P-CCPCH传输的信息, WCDMA网络为公共导频信道 CPICH传输的信息 )后, 则认为已搜索到该小 区, 即小区搜索成功, 进行(d ); 如果该频点的小区搜索失败, 则继续选择下 一个 RSSI高的频点进行搜索, 直到小区搜索成功, 或者所有需要进行小区搜 索的频点都搜索失败。 ( d ) 尝试驻留搜索成功的小区, 如果驻留成功则搜网过程结束, 如果驻 留失败则进行(b )。 驻留小区的过程包括:
( dl )接收该小区的所有系统消息。 手机监听该小区的广播控制信道 ( BCCH ), 接收 BCCH传输的通用信息, 即系统消息。
( d2 )如果接收成功则进行(d3 ), 如果接收失败则驻留失败。 如果手机 接收到 BCCH的全部系统消息后, 储存在终端卡 1中, 则进行(d3 ); 否则驻 留小区失败。
( d3 )如果该小区的接收信号强度( GSM网络为接收信号强度指示 RSSI, TD-SCDMA网络或 WCDMA网络为接收信号码功率 RSCP )符合网络要求的 最低接入门限, 小区所属的位置区未被禁止, 小区未被阻塞(bar ), 小区的网 号属于终端卡 1所属运营商的网络(即小区可以驻留), 则驻留成功; 否则驻 留失败。
步骤 S12, 终端卡 1成功驻留第一小区,接着执行步骤 S13。 本实施例中, 指定开机搜网的终端卡为终端卡 1 , 其驻留小区成功后, 终端卡 1定为第一终 端卡, 其成功驻留的小区为第一小区。 若终端卡 1搜网和驻留小区失败, 则可 以继续令终端卡 2进行搜网, 若终端卡 2成功驻留小区, 则将终端卡 2定为第 一终端卡, 其成功驻留的小区为第一小区。在其他实施例中也可以指定先终端 卡 2进行搜网, 或者, 终端卡 1和终端卡 2分别进行搜网和驻留小区, 最先搜 网和驻留小区成功的终端卡为第一终端卡, 其驻留成功的小区为第一小区。
步骤 S13, 判断终端卡 2与终端卡 1是否属于相同的运营商, 若是则执行 步骤 S21 , 若否则执行步骤 S14。 通过读取终端卡 1和终端卡 2的国际移动用 户识别码(IMSI )可以判断两张卡是否属于同一运营商, 如果两张卡属于相同 的运营商, 则让终端卡 2与终端卡 1驻留相同的小区, 即让终端卡 2驻留第一 小区; 如果两张卡属于不同的运营商, 则继续判断终端卡 2是否满足其他可以 与终端卡 1驻留相同小区的情形。
步骤 S14, 判断第一小区的网号是否存在于终端卡 2的 EHPLMN列表或 EPLMN列表, 或者第一小区的网号是否是终端卡 2的 RPLMN, 若是则执行 步骤 S21 , 若否则执行步骤 S15。 如果两张卡属于不同运营商, 则继续判断是 否还有其他可能的情况, 可以令终端卡 2与终端卡 1驻留相同的小区,如第一 小区的网号是否存在于终端卡 2的 EHPLMN列表或 EPLMN列表中, 或者第 一小区的网号是否是终端卡 2的 RPLMN。 其中, 第一小区的网号通过读取终 端卡 1接收到的 BCCH的系统消息获取; 终端卡 2的 EHPLMN列表可以通过 读取终端卡 2获得,终端卡 2的 EPLMN列表可以从手机的非易失性随机访问 存储器(NV, 用于保留手机下次开机后需要使用的信息) 中读取; 终端卡 2 的 RPLMN是终端卡 2上次成功注册过的网络, 可以通过读取终端卡 2获得。 如果第一小区的网号存在于终端卡 2的 EHPLMN列表或 EPLMN列表, 或者 第一小区的网号是终端卡 2的 RPLMN, 则让终端卡 2与终端卡 1驻留相同的 小区, 即让终端卡 2驻留第一小区; 如果第一小区的网号既不在终端卡 2的 EHPLMN列表中, 也不在 EPLMN列表中, 也不是终端卡 2的 RPLMN, 则尝 试让终端卡 2驻留其他可用小区。
步骤 S15, 终端卡 2搜网并驻留其他可用小区, 接着执行步骤 S16。 终端 卡 2搜网和驻留小区过程可以参考步骤 S 11。
步骤 S16, 判断终端卡 2是否成功驻留其他小区, 若是则执行步骤 S17, 若否则执行步骤 S21。 如果终端卡 2成功驻留第一小区外的其他小区, 则终端 卡 2进行小区 (第一小区外的其他小区) 注册; 如果终端卡 2驻留小区失败, 即无法正常驻留网络, 则只能受限驻留, 因此也可以强制终端卡 2驻留第一小 区, 终端卡 2仅可以发起受限业务(如紧急呼叫)。
步骤 S17, 终端卡 2进行小区注册, 接着执行步骤 S18。
步骤 S18, 判断终端卡 2注册小区是否成功, 若是则执行步骤 S19, 若否 则执行步骤 S21。 如果终端卡 2完成小区注册, 则终端卡 2待机在该小区的网 络; 如果终端卡 2注册被该小区的网络拒绝(如终端卡 2处于欠费状态), 则 只能受限驻留, 因此也可以强制终端卡 2驻留第一小区, 终端卡 2仅可以发起 受限业务。
步骤 S19, 终端卡 1进行第一小区注册。 终端卡 2完成小区注册后, 终端 卡 1进行第一小区注册; 终端卡 1完成第一小区注册后, 终端卡 1和终端卡 2 分别驻留在不同小区, 终端卡 1在第一小区的网络待机或进行业务, 终端卡 2 在另一小区的网络待机或进行业务。
步骤 S21 , 终端卡 2驻留第一小区, 接着执行步骤 S22。 如果终端卡 1和 终端卡 2属于同一运营商, 或者第一小区的网号存在于终端卡 2的 EHPLMN 列表, 或者第一小区的网号存在于终端卡 2的 EPLMN列表, 或者第一小区的 网号是终端卡 2的 RPLMN, 或者终端卡 2驻留其他小区失败, 或者终端卡 2 注册其他小区的网络被拒绝, 则强制终端卡 2与终端卡 1驻留相同的小区, 即 第一小区。 由于在终端卡 1搜网并成功驻留第一小区的过程中,储存了接收的 第一小区的系统消息,因此终端卡 2可以直接从终端卡 1读取第一小区的系统 消息, 这样终端卡 2驻留第一小区的时间显著缩短。
步骤 S22, 终端卡 1进行第一小区注册, 终端卡 2进行第一小区注册。 当 判断终端卡 1和终端卡 2可以驻留相同小区时强制两张卡驻留相同小区,终端 卡 1和终端卡 2轮流完成小区注册后,终端卡 1和终端卡 2都待机在第一小区 的网络, 手机监听寻呼信道(PCH ), 可以同时接收两张卡的寻呼消息, 并分 别通知到两张卡, 这样提高了寻呼接收效率, 避免了寻呼丢失。
图 3为本实施例的多卡多待终端的同步方法的重选过程流程图, 具体地, 即为双卡双待手机在重选过程中双卡小区同步的详细流程图。在开机后,如果 终端卡 1和终端卡 2都驻留在第一小区, 则两张卡可以共享邻区测量信息,提 高了测量效率, 当终端卡 1发生小区重选时, 终端卡 2也可以同步重选到终端 卡 1重选并成功驻留的小区, 也就是说, 在开机后, 如果判断终端卡 1和终端 卡 2可以驻留相同小区时,终端卡 1和终端卡 2可以始终同步驻留在相同的小 区。
步骤 S23, 终端卡 1和终端卡 2驻留在第一小区。 在终端卡 1和终端卡 2 依次完成第一小区的注册后, 终端卡 1和终端卡 2待机在第一小区的网络,或 在第一小区的网络进行业务。
接着执行步骤 S24, 进行邻区测量并将测量结果报告给终端卡 1 (主卡)。 物理层进行邻区测量, 主要是测量第一小区的邻区的接收信号强度, 并且将邻 区测量结果报告给终端卡 1。 由于终端卡 1和终端卡 2驻留在相同的小区, 因 此只需将测量结果报告给一张终端卡即主卡, 由主卡进行重选评估。 其中, 邻 区测量结果可以是邻区的接收信号强度排序后的结果。手机在开机状态下, 物 理层每隔一段时间会测量当前小区的邻区的接收信号强度并将测量结果上报 给终端卡 1。
步骤 S25, 终端卡 1判断是否有符合重选条件的第二小区, 若是则执行步 骤 S26, 若否则继续执行步骤 S25。 随着手机的移动, 周围无线环境发生变化, 终端卡驻留的当前小区的信号强度可能会减弱,而邻区中可能会有一个小区的 信号强度逐渐增强,因此终端卡就需要从当前小区重选到另一个更适合驻留的 小区。终端卡 1根据物理层上报的邻区测量结果进行重选评估, 即判断第一小 区的邻区中是否有符合重选条件的小区,符合重选条件的小区是指该小区的接 收信号强度大于预设阈值(例如网络要求的最低接入门限)且持续预定时间(例 如 5s ), 如果有则设定该小区为第二小区, 接着执行步骤 S26; 如果没有符合 重选条件的小区则终端卡 1 继续根据物理层上报的邻区测量结果进行重选评 估。
步骤 S26, 终端卡 1重选到第二小区。 如果终端卡 1根据邻区测量结果确 定存在第二小区 (即符合重选条件的小区), 则终端卡 1重选第二小区, 即尝 试接收第二小区的系统消息, 若终端卡 1接收到第二小区的全部系统消息, 并 且根据系统消息可以判断出:该小区的接收信号强度符合网络要求的最低接入 门限, 小区所属的位置区未被禁止, 小区未被阻塞, 小区的网号属于终端卡 1 所属运营商的网络, 则终端卡 1成功驻留第二小区, 即终端卡 1重选到了第二 小区。在终端卡 1重选到第二小区的过程中, 终端卡 1可以储存接收到的第二 小区的系统消息。
接着执行步骤 S27, 终端卡 2重选到第二小区。 在开机过程的双卡小区同 步中, 已经判断出终端卡 2可以与终端卡 1驻留相同的小区, 因此当终端卡 1 重选到第二小区后, 则强制终端卡 2重选到终端卡 1成功驻留的小区, 即第二 小区。 由于在终端卡 1重选到第二小区的过程中,储存了接收的第二小区的系 统消息, 因此终端卡 2可以直接从终端卡 1读取第二小区的系统消息, 这样终 端卡 2驻留第二小区的时间显著缩短。
步骤 S28, 终端卡 1进行第二小区注册, 终端卡 2进行第二小区注册。 终 端卡 1和终端卡 2轮流完成小区注册后,终端卡 1和终端卡 2都待机在第二小 区的网络, 手机监听 PCH, 可以同时接收两张卡的寻呼消息, 并分别通知到 两张卡, 这样提高了寻呼接收效率, 避免了寻呼丢失。 此外, 终端卡 1和终端 卡 2的邻区测量和 d、区重选仍保持同步。

实施例 2
本实施例的多卡多待终端的同步方法包括:
步骤 S3A,第一终端卡根据邻区测量结果判断是否有符合重选条件的第二 小区, 若是, 则所述第一终端卡重选所述第二小区;
步骤 S4A,在所述第一终端卡成功驻留所述第二小区后,控制第二终端卡 重选到所述第二小区。
图 5为本实施例的多卡多待终端的同步方法的流程图,本实施例的双卡双 待手机在重选过程中保持双卡小区同步, 而在开机过程并不进行双卡小区同 步, 但也具有提高寻呼接收效率和邻区测量效率, 降低终端功耗, 缩短终端卡 的小区驻留时间和筒化物理层实现和重选行为等较佳的效果。
首先执行步骤 S30, 终端卡 1和终端卡 2驻留在不同小区。 在开机后, 终 端卡 1和终端卡 2分别进行搜网并驻留小区, 由于是各自独立搜网, 则终端卡 1和终端卡 2可能驻留在不同的小区。 在本实施例, 将最先搜网并成功驻留小 区的终端卡设定为第一终端卡(主卡 ), 例如为终端卡 1。 终端卡 1和终端卡 2 的搜网及驻留小区的过程可以参考实施例 1的步骤 Sll。
接着执行步骤 S31 , 进行邻区测量并将测量结果报告给终端卡 1。 物理层 进行邻区测量, 主要是测量终端卡 1当前驻留的小区的邻区的接收信号强度, 并且将邻区测量结果报告给终端卡 1。 对于多卡多待单通系统, 由于只有一套 通讯模块, 为避免分时切换两张卡的重选导致的功耗增加, 可以指定先进行主 卡的邻区测量, 并将邻区测量结果报告给主卡, 由主卡进行重选评估。 其中, 邻区测量结果可以是邻区的接收信号强度排序后的结果。 手机在开机状态下, 物理层每隔一段时间会测量当前小区的邻区的接收信号强度并将测量结果上 报给终端卡 1。
接着执行步骤 S32, 终端卡 1判断是否有符合重选条件的第二小区, 若是 则执行步骤 S33, 若否则继续执行步骤 S32。
步骤 S33, 终端卡 1重选到第二小区。 步骤 S32和 S33可对应参考实施例 1的步骤 S25和 S26。
接着执行步骤 S34, 判断终端卡 2与终端卡 1是否属于相同的运营商, 若 是则执行步骤 S41 , 若否则执行步骤 S35。 终端卡 1重选到 (即成功驻留)第 二小区后, 通过读取终端卡 1和终端卡 2的国际移动用户识别码( IMSI )可以 判断两张卡是否属于同一运营商,如果两张卡属于相同的运营商, 则让终端卡 2与终端卡 1驻留相同的小区, 即让终端卡 2驻留第二小区; 如果两张卡属于 不同的运营商,则继续判断终端卡 2是否满足其他可以与终端卡 1驻留相同小 区的情形。
步骤 S35, 判断第二小区的网号是否存在于终端卡 2的 EHPLMN列表或 EPLMN列表, 或者第二小区的网号是否是终端卡 2的 RPLMN, 若是则执行 步骤 S21 , 若否则执行步骤 S36。 如果两张卡属于不同运营商, 则继续判断是 否还有其他可能的情况, 可以令终端卡 2与终端卡 1驻留相同的小区,如第二 小区的网号是否存在于终端卡 2的 EHPLMN列表或 EPLMN列表中, 或者第 二小区的网号是否是终端卡 2的 RPLMN。 其中, 第二小区的网号通过读取终 端卡 1接收到的 BCCH的系统消息获取; 终端卡 2的 EHPLMN列表可以通过 读取终端卡 2获得,终端卡 2的 EPLMN列表可以从手机的非易失性随机访问 存储器(NV, 用于保留手机下次开机后需要使用的信息) 中读取; 终端卡 2 的 RPLMN是终端卡 2上次成功注册过的网络, 可以通过读取终端卡 2获得。 如果第二小区的网号存在于终端卡 2的 EHPLMN列表或 EPLMN列表, 或者 第二小区的网号是终端卡 2的 RPLMN, 则让终端卡 2与终端卡 1驻留相同的 小区, 即让终端卡 2驻留第二小区; 如果第二小区的网号既不在终端卡 2的 EHPLMN列表中, 也不在 EPLMN列表中, 也不是终端卡 2的 RPLMN, 则继 续执行步骤 S36。
步骤 S36, 终端卡 2重选其他可用小区,接着执行步骤 S37。 本实施例中, 如果步骤 S34和 S35的判断结果均为否时,则接着进行终端卡 2的重选,包括: 物理层进行邻区测量,主要是测量终端卡 2当前驻留的小区的邻区的接收信号 强度, 并且将邻区测量结果报告给终端卡 2; 终端卡 2判断是否有符合重选条 件的小区(第二小区外的其他小区 ),如果有则终端卡 2重选其他可用小区(更 适合驻留的小区), 接着执行步骤 S37; 如果没有则终端卡 2继续驻留在当前 小区, 结束重选过程。
步骤 S37, 判断终端卡 2是否成功驻留其他小区, 若是则执行步骤 S38, 若否则执行步骤 S41。 如果终端卡 2成功驻留第二小区外的其他小区, 则终端 卡 2进行小区 (第二小区外的其他小区) 注册; 如果终端卡 2驻留小区失败, 即无法正常驻留网络, 则只能受限驻留, 因此也可以强制终端卡 2驻留第二小 区, 终端卡 2仅可以发起受限业务(如紧急呼叫)。
步骤 S38, 终端卡 2进行小区注册, 接着执行步骤 S39。
步骤 S39, 判断终端卡 2注册小区是否成功, 若是则执行步骤 S40, 若否 则执行步骤 S41。 如果终端卡 2完成小区注册, 则终端卡 2待机在该小区的网 络; 如果终端卡 2注册被该小区的网络拒绝(如终端卡 2处于欠费状态), 则 只能受限驻留, 因此也可以强制终端卡 2驻留第二小区, 终端卡 2仅可以发起 受限业务。
步骤 S40, 终端卡 1进行第二小区注册。 终端卡 2完成小区注册后, 终端 卡 1进行第二小区注册; 终端卡 1完成第二小区注册后, 终端卡 1和终端卡 2 分别驻留在不同小区, 终端卡 1在第二小区的网络待机或进行业务, 终端卡 2 在另一小区的网络待机或进行业务。
步骤 S41 , 终端卡 2重选到第二小区, 接着执行步骤 S42。 如果终端卡 1 和终端卡 2属于同一运营商,或者第二小区的网号存在于终端卡 2的 EHPLMN 列表, 或者第二小区的网号存在于终端卡 2的 EPLMN列表, 或者第二小区的 网号是终端卡 2的 RPLMN, 或者终端卡 2驻留其他小区失败, 或者终端卡 2 注册其他小区的网络被拒绝, 则强制终端卡 2与终端卡 1驻留相同的小区, 即 第二小区。 由于在终端卡 1搜网并成功驻留第二小区的过程中,储存了接收的 第二小区的系统消息,因此终端卡 可以直接从终端卡 1读取第二小区的系统 消息, 这样终端卡 2驻留第二小区的时间显著缩短。
步骤 S42, 终端卡 1进行第二小区注册, 终端卡 2进行第二小区注册。 当 判断终端卡 1和终端卡 2可以驻留相同小区时强制两张卡驻留相同小区,终端 卡 1和终端卡 2轮流完成小区注册后,终端卡 1和终端卡 2都待机在第一小区 的网络, 手机监听寻呼信道(PCH ), 可以同时接收两张卡的寻呼消息, 并分 别通知到两张卡, 这样提高了寻呼接收效率, 避免了寻呼丢失。
并且, 两张卡可以共享邻区测量信息, 提高了测量效率, 当终端卡 1发生 小区重选时, 终端卡 2也可以同步重选到终端卡 1重选并成功驻留的小区,也 就是说, 在开机重选后, 如果判断终端卡 1和终端卡 2可以驻留相同小区时, 终端卡 1和终端卡 2可以始终同步驻留在相同的小区。 需要说明的是, 上述步骤 S35和 S36也可以在步骤 S31前进行, 即在开 机过程就可以先进行步骤 S35和 S36,记录判断结果;而在执行步骤 S33之后, 可以增加步骤: 读取步骤 S35和 S36的判断结果, 若步骤 S35或 S36的判断 结果为是则执行步骤 S41 , 若步骤 S35和 S36的判断结果均为否则执行步骤 S36。
对应本实施例的同步方法, 本实施例的多卡多待终端的同步装置包括: 判断单元, 用于确定第一终端卡, 并判断其他终端卡中是否存在第二终端 卡, 所述第二终端卡为适合与所述第一终端卡驻留相同小区的终端卡;
