Description

一种单卡多待终端、 适配模块及 SIM卡访问方法
技术领域
本发明涉及移动终端领域, 尤其涉及一种通过单个 SIM卡实现单卡多待 的 SIM卡访问方法和单卡多待终端。
背景技术
随着移动互联网业务的迅猛发展, 用户对业务体验、 带宽以及高级多媒 体应用的需求日益增长。 LTE作为 3G的后续演进技术, 不但可以为用户提 供与当今家庭 xDSL和有线电视带宽连接相媲美的用户体验, 而且还可以大 幅提高容量以及系统吞吐率, 使得单用户带宽有所保障, 同时扁平化的网络 架构可以进一歩压缩传输时延, 大大提升用户的业务体验。
对于运营商而言, LTE最大的优势在于其带宽成本很低, 可以在移动环 境中经济高效、 切实可行地为用户提供大量典型的移动宽带业务, 特别是可 以将固定网络上的业务迁移到移动网络中来, 促进固定网络和移动网络的融 合, 为运营商吸引更多用户和业务量。
但是, LTE是一种纯分组域技术, 后续如何解决 LTE终端对话音业务的 支持一直是产业界各方研究的热点。 从目前 LTE终端芯片产业发展现状、 系 统设备能力、 LTE话音解决方案性能以及标准化等诸多方面综合考虑, 多模 双待终端方案是现阶段解决 LTE话音问题的一种最切实有效的方案。
该方案可以在不改变运营商 2G和 3G网络的条件下,一方面依托现有 2G 或 3G 网络成熟的电路域为用户提供话音、 可视电话、 短信、 彩信等业务, 另一方面还可以借助 LTE网络、 3G网络和 2G网络的分组域为用户提供涵盖 高速、 中速以及低速的各类数据业务。 可以说, 多模双待终端方案不但有利 于运营商整合多网优势, 还可以为用户提供更加灵活的业务使用方式和更加 多样化的服务。
目前市场上已推出的主流双卡双待终端包括 GSM/GSM单模双待终端、 GSM/TD-SCDMA 双模双待终端、 GSM/CDMA2000 双模双待终端以及
GSM/WCDMA双模双待终端等。其中,上述双卡双待终端为确保两种无线通 信模式同时工作, 需要在终端同时插入两张 SIM或复合 USIM卡。 但是, 若 双待终端的产生不是为了满足用户对两个号码的需求时, 那么再采用双卡双 待的架构就会产生诸多负面影响。
也就是说, 现有技术存在着以下的技术缺点:
现有技术方案为确保两套无线通信模块同时工作, 需要用户在终端同时 插入两张 SIM或复合 USIM卡。 但是, 当双卡双待终端的产生不是为了服务 于用户对两个号码的需求时, 再让用户使用此类终端就会引来诸多问题。 最 常见的是, 当两套无线通信模块中的一套用于承载 CS 业务, 另一套用于承 载 PS业务时, 采用双卡方案会存在如下缺陷:
1. 若终端的主卡和副卡不绑定, 采用分别计费的方式, 则用户使用运营 商自有业务时体验较差且无法统一付费, 例如: 通过两张卡使用同一个业务 时需要订购两次, 存在两个登录帐号, 比如飞信、 PIM业务。
2. 若终端采用主卡、 副卡绑定, 并通过主卡付费, 这样虽然可以解决主 副卡分离引起的自有业务用户体验以及付费不方便的问题, 但是会引起计费 风险以及其它的业务使用体验、 网络和业务平台需修改 /升级等问题。
此外,双卡架构在终端设计时还会带来占用 PCB (Printed Circuit Board, 印刷电路板) 面积较大、 终端成本较高、 设计复杂度高等缺陷。
为了解决双卡双待方案所带来的上述问题, 可以采用单卡双待方案, 但 是目前采用该方案存在如下缺陷:
1. 需要芯片厂商对两套无线通信模块中的基带芯片接口和软件模块进 行定制开发和修改, 使得产品通用性差, 终端厂商不能灵活更换某一基带芯 片的供货商, 导致终端成本无法有效降低。
2. 由于需要两个基带芯片之间配合, 使得终端厂商必须尽量采用同一个 芯片厂商提供的两套无线通信模块, 否则, 因为商务合作方面的顾虑, 芯片 厂商通常不愿意将自己的接口开放给第三方芯片厂商, 由此会限制终端厂商 的供应链, 提高了终端厂商进行双待单卡终端研发的门槛, 迫使在 2G、 3G 领域没有研发经验的新兴芯片厂商很难参与方案提供,对产业链发展不健康。
3. 为实现单卡双待方案, 每个厂商需要各自对其通信模块进行定制开发 和修改, 使得终端产品投放市场的周期比较长, 整个产业资源无法得到有效 利用。
4. 每个芯片厂商的修改方案各异, 没有统一的标准, 容易造成终端性能 参差不齐。 发明内容

系统实施例:
以下结合附图和具体实施例来对本发明进行详细的描述。
在该实施例之中, 所述单卡多待终端是单卡双待终端。
图 1是本发明单卡多待终端的一个实施例的结构示意图;
如图 1所示, 所述单卡多待终端, 其包含了两套独立的无线通信模块 1 和 2以及单个 SIM卡 5, 其中, 无线通信模块 1包括第一射频前端 11、 第一 射频芯片 21、 第一基带芯片 31 ; 无线通信模块 2包括第二射频前端 12、 第 二射频芯片 22、 第二基带芯片 32。 本发明之中, 在所述第一基带芯片 31和 第二基带芯片 32与 SIM卡 5之间设有一适配模块 4。
其中, 所述适配模块 4接收基带芯片向 SIM卡发起的 SIM卡访问请求; 同时, 其按照 SIM卡访问请求的优先级特征和 /或 SIM卡的占用状态控制对 应的基带芯片和 SIM卡之间进行访问和信息交互。
图 2是本发明单卡多待终端的一个实施例的连接示意图;
如图 2所示, 所述第一基带芯片 31之中, 包括, 第一协议栈单元 311和 第一 SIM卡管理单元 (SIM Manager) 312, 其中, 第一 SIM卡管理单元 312 用于向适配模块 4发起 SIM卡访问请求。所述第二基带芯片 32之中,包括, 第二协议栈单元 321和第二 SIM卡管理单元 (SIM Manager) 322, 其中, 第 二 SIM卡管理单元 322用于向适配模块 4发起 SIM卡访问请求。
参照图 2, 所述适配模块 4具体又包括:
互斥及优先级控制单元 41,其主要用于接收并根据多个 SIM卡访问请求 的优先级特征对所述 SIM卡访问请求进行排序并形成排队队列; SIM卡驱动 单元 42, 用于根据 SIM卡的占用状态将排队队列前端的 SIM卡访问请求传 递给 SIM卡 5,并驱动 SIM卡完成对应的基带芯片与 SIM卡的访问和信息交 互。
通常来说,基带芯片向 SIM卡发起访问请求是由基带芯片之中的 SIM卡 管理单元 (SIM Manager)所发起, 根据该实施例, 所述 SIM卡访问请求的信息 可以包括: 非实时性的访问请求; 或者, 开机鉴权、 路由区更新、 位置区更 新以及发起话音、 短信、 彩信、 可视电话、 PS承载类业务时的鉴权的实时性 鉴权访问请求, 这些请求相互之间具有不同的优先级特征。
图 3是本发明适配模块的互斥及优先级控制单元的示意图;
如图 3所示, 所述互斥及优先级控制单元, 具体又包括:
分配子单元, 用于对基带芯片同时发来的多个 SIM卡访问请求按照优先 级特征从高到低进行排队; 排队队列子单元, 用于放置正在排队的 SIM卡访 问请求的排队队列。
并且, 为了实现更好的按照优先级特征控制基带芯片和 SIM卡之间的访 问的技术效果, 所述互斥及优先级控制单元 41还设置有:
二次分配子单元, 用于对正在排队的和新发来的 SIM卡访问请求按照优 先级准则从高到低进行二次排序; 排队插入子单元, 用于将新的 SIM卡访问 请求放入排队队列中或者将其插入排队队列的前端。 例如, 如果新的 SIM卡 访问请求的优先级高于正在排队的 SIM卡访问请求, 则将其放入排队队列的 最前端; 如果新的 SIM卡访问请求小于正在排队的 SIM卡访问请求, 则将其 放入对应的排队队列位置处。
通过上述设计,所述适配模块能够解决各种 SIM卡访问请求的冲突问题, 显而易见的是, 在所述互斥及优先级控制单元中进行排队的复杂度小于现有 技术中在 SIM卡驱动单元 (SIM Manager) 中排队的复杂度;
并且, 由于在该实施例之中, 所述互斥及优先级控制单元的排队规则多 是基于业务的实时性或者业务优先级高低进行排序, 进而, 其对于用户体验 和确保业务实时性具有较好的技术效果。
图 4是本发明单卡多待终端的一个实施例的硬件连接示意图; 如图 4所示, 所述适配模块 4上不仅包括 VCC、 GND管脚, 还设有三 套 RST、 CLK和 I/O管脚, 其中, 两套用于和所述第一基带芯片 31和第二基 带芯片 32上的 RST、 CLK和 I/O管脚相连并进行信息交互; 另一套用于和 SIM卡的 RST、 CLK和 I/O管脚相连并进行信息交互。
在该实施例之中, 所述适配模块 4可以由可编程芯片制成, 例如, 选取 在集成电路设计领域较为常见的 ASIC(Application Specific Integrated Circuits, 专用集成电路)芯片, 并在 ASIC芯片中写入设定的指令和计算逻辑, 然后, 将 ASIC芯片的引脚与上述 RST、 CLK和 I/O管脚相连接, 进而可以实现利 用上述 UICC (Universal Integrated Circuit Card, 通用集成电路卡) 接口与对 应的基带芯片和 SIM卡连接并相互之间进行访问和信息交互的目的。 本领域 的技术人员能够知晓, 所述适配模块 4的硬件实现方式上也可以采取其他可 编程芯片或者硬件模块 +软件 /指令的方式实现, 在此不再赘述。
此外, 参照图 2, 所述适配模块与第一基带芯片 31、 第二基带芯片 32以 及 SIM卡 5都通过标准的 Cu接口进行通信; 且, 在该实施例之中, 所述第 一基带芯片 31通过 UART接口与一个应用处理器 6连接;所述第二基带芯片 32通过 USB2.0接口与所述应用处理器 6进行连接, 其中, 应用处理器 6和 第一基带芯片 31和第二基带芯片 32的交互是本领域技术人员熟知的技术, 在此不进行描述。
本发明在采取了上述技术方案以后, 在硬件方面, 上述基带芯片和 SIM 卡在设计上都不需要进行更改, 仅仅需要增加一个适配模块, 且其采用标准 的软硬件接口; 并且, 所述适配模块能够根据多个基带芯片发起的 SIM卡访 问请求的优先级进行对应的访问控制, 以使多个基带芯片在同一个终端上能 够通过一张 SIM卡同时接入并工作在多个网络系统之中, 进而实现终端的单 卡多待, 并且, 该发明可以确保终端厂商有更加灵活的芯片选择余地, 从而 可以大大降低终端的成本。
方法实施例一:
以下结合附图和具体实施例对本发明的单卡多待终端的 SIM卡访问方法 进行描述, 具体来说, 本发明之中, 对于 SIM卡的访问方法是依照优先级特 征控制基带芯片对 SIM卡的方法而实现的, 具体来说, 所述方法包括: A、 接收由多个基带芯片发起的 SIM卡访问请求;
B、按照所述 SIM卡访问请求的优先级特征和 /或 SIM卡的占用状态控制 对应的基带芯片和 SIM之间的访问和信息交互。
其中, 所述 SIM卡访问请求由基带芯片中的 SIM卡管理单元发起; 且在 本实施例之中, 所述 SIM卡访问请求包括: 非实时性业务访问请求;
或者, 开机鉴权或路由区更新或位置区更新或者发起话音或短信或彩信 或可视电话或 PS承载类业务时的实时性业务鉴权访问请求, 这些 SIM卡访 问请求相互之间具有不同的优先级特征。
由此, 在歩骤 B中, 其可以采取根据 SIM卡访问请求的业务优先级高低 进行排序; 也可以采取根据 SIM卡访问请求的实时性要求优先级高低进行排 序, 进而达到根据 SIM卡访问请求的优先级特征控制对应的基带芯片和 SIM 卡之间的访问和信息交互的目的。
更具体地,当多个基带芯片同时向 SIM卡发起访问请求的时候,所述 SIM 卡访问请求被传送到适配模块中的互斥及优先级控制单元之中, 所述互斥及 优先级控制单元根据前述优先级特征按照优先级高低从高到低进行排序并形 成排队队列; 在 SIM卡未被占用时, 互斥及优先级控制单元将排队队列前端 的 SIM卡访问请求传递给 SIM卡驱动单元,进而控制对应的基带芯片和 SIM 卡之间进行访问和信息交互。
此外, 当某一基带芯片向适配模块发起新的 SIM卡访问请求时, 此时, 如果在前已经有正在进行排队的排队队列, 此时所述互斥及优先级控制单元 会对正在排队的和新发来的 SIM卡访问请求按照优先级特征从高到低进行排 序, 并将处于高优先级的 SIM卡访问请求插入排队队列的前端, 当 SIM卡处 于非占用状态, 则将该前端的 SIM卡访问请求传给 SIM卡。
通过上述方法, 本发明能够根据多个基带芯片发起的 SIM卡访问请求的 优先级进行对应的控制, 以使多个基带芯片在同一个终端上能够通过一张 SIM卡同时接入并工作在多个网络系统之中, 进而实现终端的单卡多待, 并 解决实时和非实时性的业务之间的业务冲突问题。
以下结合图 5对本发明进行详细的描述。
图 5是本发明单卡多待终端的 SIM卡访问方法的一个具体实施例的流程 示意图; 其表示了两个基带芯片同时发起的 SIM卡访问请求的处理过程, 如 图 5所示, 所述方法具体包括:
S101 : 第一基带芯片和第二基带芯片通过各自的第一 SIM 卡管理单元 (SIM Manager) 和第二 SIM卡管理单元 (SIM Manager)向适配模块同时请求 访问 SIM卡;
S102: 适配模块判断所述第一 SIM Manager的 SIM卡访问请求的优先级 是否大于第一 SIM Manager的 SIM卡访问请求;
其中, 如果所述第一 SIM Manager的 SIM卡访问请求的优先级大于第二 SIM Manager的 SIM卡访问请求, 则 S103: 控制第一 SIM Manager与 SIM 卡之间进行信息交互;
如果所述第一 SIM Manager的 SIM卡访问请求的优先级小于第二 SIM Manager的 SIM卡访问请求, 贝 lj S104: 控制第二 SIM Manager与 SIM卡之 间进行信息交互。
例如, 在更具体的实施例中, 设定所述第一基带芯片 31承载的是话音业 务, 第二基带芯片 32承载的是数据业务, 显然, 话音业务的优先级大于数据 业务的优先级。
此时, 则当两者访问 SIM卡出现冲突时, 互斥及优先级控制模块 41根 据话音业务优先级高于数据业务的准则将第一基带芯片的 SIM Manager中的 SIM卡访问请求排在队列最前端,并将其先传给 SIM卡进行访问和 SIM卡信 息交互。 由此, 该发明不光能够满足各种业务的实时性要求, 还能够解决实 时和非实时性的业务之间的业务冲突问题。
方法实施例二- 以下以一个单独的基带芯片向 SIM卡发起访问请求的完整的流程进行描 述。 其中, 图 6是本发明单卡多待终端的 SIM卡访问方法的流程示意图。
如图 6所示, 所述处理方法具体包括:
S1 : 第一基带芯片的第一 SIM Manager (或者第二基带芯片的第二 SIM Manager ) 发起一个新的访问 SIM卡的 SIM卡访问请求;
S2: 互斥及优先级控制单元查询其排队队列子单元, 查询是否有优先级 排队队列在等待; 其中, 如果有, 则需要对现有的正在排队的和新的 SIM请 求进行排队, 具体来说, 需要根据新的 SIM卡访问请求的优先级特征判断 是否将其插入排队队列前端还是排队队列中间。
例如, 在歩骤 S3: 中, 如果 SIM卡访问请求具有插入排队队列前端的高 优先级特征, 则 S4: 利用排队插入子单元将该 SIM卡访问请求信息插入优先 级队列的最前端, 并当 SIM卡空闲时将其传送给 SIM卡以完成交互。
此外, 如果所述 SIM卡访问请求不具有插入排队队列前端的特征, 则进 入歩骤 S4': 由分配子单元根据该 SIM卡访问请求和已进行排队的 SIM卡访 问请求按照优先级特征进行排队, 并将上述优先级队列放入排队队列子单元 之中。
其中, 如果在歩骤 S2中, 如果所述互斥及优先级控制单元查询并没有优 先级排队队列在等待, 则此时说明该 SIM 卡访问请求前并没有相互冲突的 SIM卡访问请求, 则此时, 需要进入歩骤 S3': SIM卡驱动单元判断 SIM卡 是否已被占用; 如果 S5': SIM卡处于可用状态, 贝 lj, S6: SIM卡驱动单元将 该 SIM卡访问请求传递给 SIM卡进行处理; 接着, S7: 所述 SIM卡将处理 后的结果反馈给发出该卡访问请求信息的基带芯片并告知互斥及优先级控制 单元该 SIM卡访问请求信息处理完毕, 从而完成上述 SIM卡访问过程。
其中, 如果在歩骤 S3'中, 如果 SIM卡已经被占用; 则进入歩骤 S5:互斥 及优先级控制单元判断是否有新的 SIM卡访问请求, 其中, 如果有新的 SIM 卡访问请求, 则重复上述歩骤 S3、 S4或 S4', 在此不赘述。
需要说明的是, 上述实施例之中, 所述的 SIM卡可以适用于 USIM卡, 这些是本领域所能够知晓的。 且上述实施例中以单卡双待终端进行描述, 但 是本领域技术人员能够知晓, 上述方案也可以应用于超过两个基带芯片的单 卡多待终端。 SP : 当终端具备多个基带芯片同时访问 SIM卡时, 可以将上述 适配模块的接口管脚增加, 其中: 每增加一个基带芯片, 贝 lj增加一套 RST、 CLK、 I/O管脚, 所述互斥及优先级控制单元以及 SIM驱动单元则只需稍作 调整, 在此不赘述。
最后应说明的是: 以上所述仅为本发明的优选实施例而已, 并不用于限 制本发明, 尽管参照前述实施例对本发明进行了详细的说明, 对于本领域的 技术人员来说, 其依然可以对前述各实施例所记载的技术方案进行修改, 或 者对其中部分技术特征进行等同替换。 凡在本发明的精神和原则之内, 所作 的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
