Description

终端射频干扰处理方法、 装置及终端 技术领域 本发明涉及通信领域， 具体而言， 涉及一种终端射频干扰处理方法、装置及终端。 背景技术 目前的移动通信系统存在多种模式， 包括： 以全球移动通信 （Global system for
Mobile Communication, 简称为 GSM) /通用无线分组业务 （General Packet Radio Service, 简称为 GPRS) /增强型数据速率 GSM演进技术（Enhanced Data Rate for GSM Evolution,简称为 EDGE) /码分多址（Code Distribute Multiple Access,简称为 CDMA) 为代表的第二代移动通信系统技术， 以时分同步码分多址接入 （ Time Division-Synchronized Code Division Multiple Access, 简称为 TD-SCDMA) /宽带码分 多址接入 （Wideband Code Division Multiple Access, 简称为 WCDMA) 为代表的第三 代移动通信系统技术， 以长期演进 （Long-Term Evolution, 简称为 LTE) 为代表的第 四代移动通信系统技术。这几种通信技术各有优缺点： GSM网络覆盖好，通话质量高， 但是对于数据业务速率较低； TD/W对于数据业务支持较好，可以支持电路交换 ( Circuit Switch, 简称为 CS)， 分组交换 （Packet Switched, 简称为 PS) 业务并发； LTE速率 比 TD/W更高， 但是还处于建网初期， 信号覆盖不全。 基于目前各个运营商的现状， 这几种通信技术将会在很长的一段时间内共存。 基于上述的现实， 多模双待终端应运而生。 一方面， 该终端可以满足用户的各种 应用需求， 比如在 TD/W或 LTE网络下进行高速的数据业务， 在 GSM网络下进行普 通的语音通话； 另一方面， 用户只需要携带一个终端就可以实现两个终端的功能。 在相关技术中， GSM系统使用的频段是 900HZ禾 P 1800HZ, 简称为 GSM900和 DCS1800。而 TD系统可能包括 a，b， c， d， e， f， 5个频段， LTE—般使用频段 37, 38,39,40, 图 1是根据相关技术中 GSM、 TD、 LTE制式频带分布示意图， 如图 1所示， 从图 1 中可以看到， GSM1800频段的下行， 和 TD的 F频段以及 LTE的 39频段首尾相接， 而 TD的 F频段和 LTE的 39频段则完全重合。 目前在 TD-SCDMA制式下一般支持 a频段和 f 频段。 以下将以 GSM制式和 TD-SCDMA制式为例进行阐述。 当支持 GSM和 TD两种制式的双模双待终端同时进 行业务时， 由于终端的 2个射频天线同时工作， 如果工作的频率比较接近的话， 将会 相互产生干扰， 体现在 DSC1800和 TD的 f频段， 单从工作频带上看似乎各模式频带 并没有重叠， 应该不存在干扰。 但实际由于手机尺寸限制、 手机接收滤波器的大小、 性能限制和发射机的带外辐射， 两种模式同时工作时， 必然存在着互扰， 这样将会影 响到业务的正常进行， 图 2是相关技术 GSM、 TD在 1800MHz处存在冲突的示意图， 如图 2所示， 下面对冲突的情形进行举例说明。 例如， 在下面的这三种情况， 很容易发生射频干扰：
1、 GSM在 DSC1800做语音通话， TD在 a~e频段做高速下载， 网侧要求 UE在 TD网侧切换到 f频段工作。
2、 GSM在 GSM900做语音通话， TD工作在 f频段做高速下载， 网侧要求 UE在 GSM网络切换到 DSC1800。 3、 GSM在 DSC1800做语音通话， TD工作在 f频段做高速下载。 简单的处理方式可以考虑把冲突的频段禁止或者在选网的时候选择频段不冲突的 网络， 即一旦 GSM在 DSC1800频段上驻留或者正在进行业务时， TD—待需要避开 F 频段驻留认为 F频段不可用。 这种处理方式虽然可以达到避免冲突的效果， 但是有以下弊端： 例如， 会浪费一 部分频段资源， 降低了频段资源的利用率； 一旦某一待只有冲突频段可以驻留时， 会 导致该待长时间丢网， 不能提供服务。 因此， 在相关技术中避免频段资源冲突的处理会导致资源利用低降低， 或是长时 无法使用频段， 导致用户体验降低的问题。 发明内容 本发明提供了一种终端射频干扰处理方法、 装置及终端， 以至少解决相关技术中 避免频段资源冲突的处理会导致资源利用低降低， 或是长时无法使用频段， 导致用户 体验降低的问题。 根据本发明的一个方面， 提供了一种终端射频干扰处理方法， 包括： 确定终端同 时在两个不同制式下工作时互为干扰的临界射频区域； 依据确定的所述临界射频区域 进行射频干扰处理。 其中， 依据确定的所述临界射频区域进行射频干扰处理包括： 判断所述终端启动 制式所占用的频点是否处于所述临界射频区域； 在判断结果为是的情况下， 在同一时 段允许一个制式在所述临界射频区域进行业务处理。 其中， 在同一时段允许一个制式在所述临界射频区域进行业务处理包括： 判断所 述终端在所述临界射频区域是否有正在进行业务处理的制式占用； 在判断结果为是的 情况下，等待正在进行业务处理的制式处理完业务；和 /或，在判断结果为否的情况下， 占用所述临界射频区域进行业务处理。 其中， 在占用所述临界射频区域进行业务处理之后， 还包括： 对所述临界射频区 域被占用进行标记。 其中， 所述终端工作的制式包括以下制式中的至少两个： 全球移动通信 GSM、通 用无线分组业务 GPRS、增强型数据速率 GSM演进技术 EDGE、码分多址 CDMA、 时 分同步码分多址接入 TD-SCDMA、 宽带码分多址接入 WCDMA、 长期演进 LTE。 根据本发明的另一方面， 提供了一种终端射频干扰处理装置， 包括： 确定模块， 设置为确定终端同时在两个不同制式下工作时互为干扰的临界射频区域； 处理模块， 设置为依据确定的所述临界射频区域进行射频干扰处理。 其中， 所述处理模块包括： 第一判断单元， 设置为判断所述终端启动制式所占用 的频点是否处于所述临界射频区域； 第一处理单元， 设置为在所述第一判断单元的判 断结果为是的情况下， 在同一时段允许一个制式在所述临界射频区域进行业务处理。 其中， 所述第一处理单元包括： 判断子单元， 设置为判断所述终端在所述临界射 频区域是否有正在进行业务处理的制式占用； 等待子单元， 设置为在所述判断子单元 的判断结果为是的情况下， 等待正在进行业务处理的制式处理完业务； 和 /或， 处理子 单元， 设置为在所述判断子单元的判断结果为否的情况下， 占用所述临界射频区域进 行业务处理。 优选该， 该第一处理单元还包括： 标记子单元， 设置为对所述临界射频区域被占 用进行标记。 根据本发明的还一方面， 提供了一种终端， 包括上述任一项所述的装置。 通过本发明， 采用确定终端同时在两个不同制式下工作时互为干扰的临界射频区 域； 依据确定的所述临界射频区域进行射频干扰处理， 解决了在相关技术中避免频段 资源冲突的处理会导致资源利用低降低， 或是长时无法使用频段， 导致用户体验降低 的问题， 进而达到了依据临界射频区域进行资源利用的好处， 不仅提高了资源的利用 率， 而且有效地延长提供服务的时间， 提高了用户体验的效果。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1是根据相关技术中 GSM、 TD、 LTE制式频带分布示意图； 图 2是相关技术 GSM、 TD在 1800MHz处存在冲突的示意图； 图 3是根据本发明实施例的终端射频干扰处理方法的流程图； 图 4是根据本发明实施例的终端射频干扰处理装置的结构框图； 图 5是根据本发明实施例的终端射频干扰处理装置中处理模块 44的优选结构框 图； 图 6是根据本发明实施例的终端射频干扰处理装置中处理模块 44中的第一处理单 元 54的优选结构框图一； 图 7是根据本发明实施例的终端射频干扰处理装置中处理模块 44中的第一处理单 元 54的优选结构框图二； 图 8是根据本发明实施例的终端的结构框图； 图 9是根据本发明实施例的临界区资源使用原则示意图； 图 10是根据本发明优选实施例的 "临界区"资源处理思想的示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不冲突的 情况下， 本申请中的实施例及实施例中的特征可以相互组合。 在本实施例中提供了一种终端射频干扰处理方法， 图 3是根据本发明实施例的终 端射频干扰处理方法的流程图， 如图 3所示， 该流程包括如下步骤： 步骤 S302， 确定终端同时在两个不同制式下工作时互为干扰的临界射频区域， 需 要说明的是， 终端工作的制式可以包括多种， 例如， 可以包括以下制式中的至少两个: 全球移动通信 GSM、通用无线分组业务 GPRS、增强型数据速率 GSM演进技术 EDGE、 码分多址 CDMA、 时分同步码分多址接入 TD-SCDMA、宽带码分多址接入 WCDMA、 长期演进 LTE; 步骤 S304, 依据确定的该临界射频区域进行射频干扰处理。 通过上述步骤， 依据互为干扰的临界射频区域进行射频干扰处理， 相对于相关技 术中仅仅依据不同制式而进行的冲突避免处理， 采用该方法， 通过对临界射频区域进 行处理获取到焯影响射频干扰的冲突频率， 对于不影响干扰的频率还正常应用于不同 的制式， 解决了在相关技术中避免频段资源冲突的处理会导致资源利用低降低， 或是 长时无法使用频段， 导致用户体验降低的问题， 进而达到了依据临界射频区域进行资 源利用的好处， 不仅提高了资源的利用率， 而且有效地延长提供服务的时间， 提高了 用户体验的效果。 其中， 依据确定的临界射频区域进行射频干扰处理时， 可以先判断终端启动制式 所占用的频点是否处于临界射频区域； 在判断结果为是的情况下， 在同一时段允许一 个制式在所述临界射频区域进行业务处理， 通过该判断可以提前有效地对被占用的临 界射频区域避免干扰， 即将后来不需要占用该临界射频区域的制式业务采用其它频段 进行处理。 而在在同一时段允许一个制式在所述临界射频区域进行业务处理时， 可以采用多 种处理方式， 例如， 可以采用以下较优的处理方式， 先判断终端在临界射频区域是否 有正在进行业务处理的制式占用； 在判断结果为是的情况下， 等待正在进行业务处理 的制式处理完业务； 和 /或， 在判断结果为否的情况下， 占用临界射频区域进行业务处 理。 通过此次的判断， 有效地区分了同时对两个不同制式均需要应用该临界射频区域 进行了排序， 使得业务的处理不至于冲突。 其中， 在占用临界射频区域进行业务处理之后， 还包括： 对临界射频区域被占用 进行标记。 通过标识可以简单明了地获知该临界射频区域已占用， 不仅能够有效的提 示正在使用该临界射频区域的该制式， 也可以方便其它制式获知该临界射频区域的使 用情况。 在本实施例中还提供了一种终端射频干扰处理装置， 该装置用于实现上述实施例 及优选实施方式， 已经进行过说明的不再赘述。 如以下所使用的， 术语 "模块"可以 实现预定功能的软件和 /或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来 实现， 但是硬件， 或者软件和硬件的组合的实现也是可能并被构想的。 图 4是根据本发明实施例的终端射频干扰处理装置的结构框图， 如图 4所示， 该 装置包括确定模块 42和处理模块 44， 下面对该装置进行说明。 确定模块 42， 设置为确定终端同时在两个不同制式下工作时互为干扰的临界射频 区域； 处理模块 44， 连接至上述确定模块 42， 设置为依据确定的临界射频区域进行射 频干扰处理。 图 5是根据本发明实施例的终端射频干扰处理装置中处理模块 44的优选结构框 图， 如图 5所示， 该处理模块 44包括第一判断单元 52和第一处理单元 54， 下面对该 处理模块 44进行说明。 第一判断单元 52， 设置为判断终端启动制式所占用的频点是否处于临界射频区 域； 第一处理单元 54， 连接至上述第一判断单元 52， 设置为在第一判断单元 52的判 断结果为是的情况下， 在同一时段允许一个制式在该临界射频区域进行业务处理。 图 6是根据本发明实施例的终端射频干扰处理装置中处理模块 44中的第一处理单 元 54的优选结构框图一， 如图 6所示， 该第一处理单元 54包括： 判断子单元 62、 等 待子单元 64和 /或处理子单元 66， 下面对该第一处理单元 54进行说明。 判断子单元 62， 设置为判断终端在临界射频区域是否有正在进行业务处理的制式 占用； 等待子单元 64， 连接于上述判断子单元 62， 设置为在上述判断子单元的判断结 果为是的情况下， 等待正在进行业务处理的制式处理完业务； 和 /或， 处理子单元 66， 连接于上述判断子单元 62， 设置为在判断子单元的判断结果为否的情况下， 占用临界 射频区域进行业务处理。 图 7是根据本发明实施例的终端射频干扰处理装置中处理模块 44中第一处理单元 54的优选结构框图二， 如图 7所示， 该第一处理单元 54除包括图 6所示的所有结构 夕卜， 还包括标记子单元 72， 下面对该标记子单元 72进行说明。 标记子单元 72，连接至上述处理子单元 66，设置为对临界射频区域被占用进行标 记。 图 8是根据本发明实施例的终端的结构框图， 如图 8所示，该终端 80包括上述任 一项的终端射频干扰处理装置 82。 基于上述图 2所示的上述几种频段冲突所引起的问题， 可以看到， GSM1800频段 和 TD F频段， 只有在 1800MHZ附近干扰才会比较明显， 而在其它的频率上， 即使两 待同时分别工作在 DCS1800和 F频段也不会有问题。因此，射频冲突干扰的原因是两 待同时在相近的频率上进行收发， 所以考虑如果两待能够不在同时收发， 那么即使两 待驻留或工作在相近频率上也不会有干扰的问题。 基于上述问题， 在本实施例中提供了一种多模双待终端在射频干扰场景下切换的 方法， 通过使用 "临界区"资源的处理思想， 使得双待终端的两待能够同时待在干扰 频段上， 增加了待机时长提高了用户的满意度。 该方法包括以下步骤： 确定存在射频 干扰两待各自的 "临界区"； 终端在一个制式发起业务时， 查看该业务是否进入了 "临 界区"。 一旦进入， 则标记该制式占用了 "临界区"； 如果在另一制式发起业务时， 查 看前一制式是否进入了 "临界区"， 如果前一制式已进入， 则放弃， 否则进入； 如果某 一制式退出了 "临界区"则通知另一制式。 上述方法对硬件没有任何需求， 只需要在 终端加入上述处理就可以达到目的， 不仅不会增加硬件成本， 而且有效提高了干扰处 理的效率。 下面结合本发明优选实施例进行说明。 需要说明的是， 针对上述两种容易发生射频干扰的场景， 提供一种基于 "临界区" 思想的策略。 该 "临界区"是操作系统中的一个概念： 进程在运算的时候可能需要访 问共享内存或共享文件， 或执行另外一些会导致竞争的操作， 把对共享内存进行访问 的程序片段称作临界区域 （critical region) 或临界区 （critical section)。 需要作适当的 安排， 使得两个进程不能同处于临界区中。 图 9是根据本发明实施例的临界区资源使用原则示意图， 如图 9所示， 当进程 A 进入临界区后， 进程 B也想进入， 但是进程 B必须等待， 直到 A退出临界区时， 它才 能进入。 例如， 将 TD的 F频段与其相冲突的 GSM1800频段看成是一种 "临界区"资源， 一般来说， 这个冲突频段跟 UE性能相关， 是可以通过实验测试出来的， 例如 TD的 f 频段 mm,Fro— ]与 DSC1800 附近的 mm, ^M— max]是冲突的， 那么我们把 mm,Fro— max]看成一个 "临界区"资源。然后我们把 "使用冲突频段中的 TD频段" 与 "使用冲突频段中的 GSM频段"看成是两个进程， 这两个进程只能有一个进入 "临 界区"， 问题就很好解决了。 "使用冲突频段中的 TD频段"与 "使用冲突频段中的 GSM频段"实际上是进行 某个 TD或 GSM业务时， 占用了冲突频段。例如当驻留在冲突频段中的 TD频段的一 个小区上发起业务后， 此时不能再在冲突频段中的 GSM频段同时做业务， 包括测量、 做 CS业务等。 "临界区"表示双待终端的两待间可能产生射频干扰的一段频率范围， 该范围和 终端的硬件性能以及布局有关系， 需要通过对终端进行实际的测试才能给出具体的数 字， 即对于不同的终端来说， "临界区" 的范围一般是不相同的。 通过使用 "临界区"资源的处理思想， 可以很好的处理双待终端干扰的切换策略。 图 10是根据本发明优选实施例的 "临界区"资源处理思想的示意图， 如图 10所 示， "临界区"资源处理包括：
Sl， 确定 "临界区"。 例如 TD 的 f 频段 与 DSC1800 附近的
[F^— mm, M— J是冲突的， 那么我们把 mm, — max]看成一个 "临界区"资源；
S2, 终端在一个制式发起业务时， 查看该业务是否进入了 "临界区"， 一旦进入， 则标记该制式占用了 "临界区"； S3 , 用户如果在另一制式发起业务时， 查看前一制式是否进入了 "临界区"， 如果 前一制式已进入， 则放弃， 否则进入；
S4， 如果某一制式退出了 "临界区"则通知另一制式。 下面基于上述 "临界区"资源处理思想， 对本发明优选实施方式进行说明。 该优 选实施方式包括如下处理： S1 , 需要启动某个制式某个小区 /频点测量或在某个频点进行业务时， 首先查看另 一制式是否占用 "临界区"， 如是已经占用， 且该小区 /频点也处于 "临界区" 内， 则 不启动该小区 /频点的测量或将业务挂起等待， 反之则启动或进行业务；
S2, 当 UE从非 "临界区 "切换到 "临界区 "时， 暂时停止另一制式的 "临界区" 小区 /频点测量或业务； S3 , 当 UE从 "临界区"小区切换到非 "临界区"小区测量时， 启动另一制式 "临 界区"小区 /频点测量或业务； S4， 当 UE在两个制式上做业务， 其中制式 1在 "临界区 "上工作， 制式 2在非 "临界区"上工作， 如果网络侧要求制式 2切换到 "临界区"， 则直接报切换拒绝。 通过上述实施例及优选实施方式， 至少可以达到以下效果： 仅仅在 UE终端做相 应的修改就可以解决射频干扰的问题； 属于纯软件的实现， 对于硬件没有任何需求； 可以很容易的扩展到多个制式间的处理， 适用范围大。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块， 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 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， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 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。 工业实用性 如上所述， 通过上述实施例及优选实施方式， 不仅解决了在相关技术中避免频段 资源冲突的处理会导致资源利用低降低， 或是长时无法使用频段， 导致用户体验降低 的问题， 进而可以依据临界射频区域进行资源利用， 不仅提高了资源的利用率， 而且 有效地延长提供服务的时间， 提高了用户体验。
