Description

分量载波链路管理方法和装置 技术领域
本发明涉及通信领域，具体而言，涉及一种分量载波链路管理方法和装置。
背景技术
面对日益增长的移动宽带业务，现有单载波的能力已逐渐不能满足需求，而运营商所拥有的频谱资源比较分散，为了能有效利用频谱资源，运营商和设备商极力推动载波聚合技术(Carrier Aggregation，简称为CA)。在载波聚合技术中，用户设备(User Equipment，简称为UE)可以使用一个以上的载波资源，一方面增加了UE的最大使用资源数，从而增加UE的最大速率，另一方面也可以在更多的资源内选择更好的资源提供UE使用，从而提高了UE的频率使用效率。
但是同时为了让UE支持多载波聚合，UE也要提高自身的接收/发射机能力，并且需要同时在更多的载波以及更宽频带上接收/发射数据，UE的射频需要支持更高的带宽和更多载波支路的元器件，基带设计也需要支持更多的数据处理能力，这都增加了UE的功耗。尤其在弱信号情况下，手机会利用闭环功率控制机制提高自身的发射功率，从而导致功耗的增加。
另外，由于信号弱会频繁与网络失步而不停进行搜网，造成功耗过高；其次最重要的是载波调制使用了一个以上的载波资源，则它的耗电比一个载波资源的使用要高出很多，如果都在弱信号区域，那么耗电问题则带来了更大的挑战。

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。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种分量载波链路管理方法，图1是根据本发明实施例的分量载波链路管理方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，检测载波聚合的多个分量载波链路中每个分量载波链路的接收信号强度；
步骤S104，判断每个分量载波链路的接收信号强度是否低于预设阈值；
步骤S106，关闭多个分量载波链路中的第一分量载波链路，其中，第一分量载波链路为接收信号强度低于预设阈值的分量载波链路。
通过上述步骤，在检测到分量载波链路的接收信号强度低于预设阈值的情况下，将这些分量载波链路关闭，从而只使用其他的接收信号强度好的分量载波链路进行载波聚合通信，避免了由于分量载波链路的接收信号强度低导致的UE的耗电量增大，解决了载波聚合的用户设备耗电量高的问题，降低了载波聚合的用户设备的耗电量。
其中，上述的预设阈值可以根据需要进行设置，上述方法可以应用在支持载波聚合通信 的用户设备中，包括但不限于：移动终端。
在用户设备关闭多个分量载波链路中的第一分量载波链路之后，用户设备将多个分量载波链路中的第二分量载波链路聚合为载波聚合链路，并通过载波聚合链路进行数据任务，其中，第二分量载波链路为接收信号强度不低于预设阈值的分量载波链路。这样，进行载波聚合的分量载波链路都是信号强度高于预设阈值的分量载波链路，从而保证了载波聚合通信，降低了用户设备的功耗。
上述的关闭分量载波链路，可以是用户设备只对分量载波链路进行定期检测而不在该分量载波链路上传输用户数据；或者，用户设备既不对分量载波链路不进行检测，也不使用该分量载波链路收发用户数据。
在用户设备只对分量载波链路进行定期检测而不在该分量载波链路上传输用户数据的情况下，用户设备可以对所述第一分量载波链路的接收信号强度进行测量；并且，在判断到所述第一分量载波链路的接收信号强度不低于所述预设阈值的情况下，恢复所述第一分量载波链路
在用户设备既不对分量载波链路不进行检测，也不使用该分量载波链路收发用户数据的情况下，各个分量载波链路的接收信号强度信息可以通过主载波发送给用户设备。并且，无论用户设备是否关闭第一分量载波链路，在基站通过主载波发送给用户设备的接收信号强度信息中都包含第一分量载波链路的接收信号强度。在用户设备关闭多个分量载波链路中的第一分量载波链路之后，用户设备接收多个分量载波链路的接收信号强度；用户设备根据多个分量载波链路的接收信号强度，判断第一分量载波链路的接收信号强度是否低于预设阈值；用户设备在判断到第一分量载波链路的接收信号强度不低于预设阈值的情况下，恢复第一分量载波链路。通过这种方式，在第一分量载波的接收信号强度不低于预设阈值，即接收信号强度提高之后，可以恢复该第一分量载波链路，并将该第一分量载波链路加入载波聚合链路中，提高了分量载波链路的利用率。
在用户设备既不对分量载波链路不进行检测，也不使用该分量载波链路收发用户数据的情况下，在关闭多个分量载波链路中的第一分量载波链路时，同时可以设置关闭第一分量载波链路的第一关闭时长。在设置关闭第一分量载波链路的第一关闭时长之后，用户设备判断第一关闭时长是否超时；在第一关闭时长超时的情况下，用户设备恢复第一分量载波链路。
可选地，用户设备也可以通过周期或者不定期检测分量载波链路的接收信号强度的方式，来获取第一分量载波链路的接收信号强度。例如，在恢复第一分量载波链路之后，用户设备检测恢复的第一分量载波链路的接收信号强度；用户设备判断恢复的第一分量载波链路的接收信号强度是否低于预定阈值；在判断到恢复的第一分量载波链路的接收信号强度低于预定阈值的情况下，用户设备关闭第一分量载波链路。此外，如果判断到恢复的第一分量载波链路的接收信号强度不低于预定阈值，则可以将恢复的第一分量载波加入载波聚合链路中。
可选地，在在判断到第一分量载波链路的接收信号强度低于预定阈值的情况下关闭第一分量载波链路之后，用户设备还可以设置关闭第一分量载波链路的第二关闭时长，其中，第 二关闭时长大于或等于第一关闭时长。

可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为了使本发明实施例的描述更加清楚，下面结合可选实施例进行描述和说明。
本发明可选实施例提供了一种弱信号下的载波处理方法及载波聚合终端，以节省功耗，有效延长电池电量的使用时间，从而提升用户体验。
为了实现以上目的，本发明可选实施例提供的弱信号下的载波处理方法采用以下方案：
设UE为多载波聚合终端，因为载波聚合是将两个或者更多的分量载波(Component Carriers，简称为CC)聚合起来，所以定义各分量载波的信号强度分别为S1，S2…Sn(其中，n为载波聚合终端所支持的最大分量的载波数)，当终端开启运营商数据任务时，终端自动检 测当前的各分量载波网络信号，并根据与预定的阈值S对比结果来判断各分量载波信号是否处于弱信号状态。
如果S1>S，S2>S…Sn>S，其中所有分量载波都不在弱信号状态，终端则按照默认的正常载波聚合网络进行数据任务。
如果S1<S，S2<S…Sn<S，其中所有分量载波都在弱信号状态，终端则关闭所有载波聚合的数据任务。
如果其中有一个或多个分量载波，定义为m(m＜n)个分量载波在弱信号区域，则关掉在弱信号状态的m个分量载波的数据链路，用余下的n-m的各载波进行数据任务。以双载波聚合为例，如果S1>S，S2<S，则分量载波1不在弱信号状态，分量载波2在弱信号状态，那么关掉分量载波2的工作链路，只利用分量载波1进行数据业务的任务。反之S1<S，S2>S，则分量载波1在弱信号状态，分量载波2不在弱信号状态，那么就关掉分量载波1的工作链路，只利用分量载波2进行数据业务的任务。
如果检测到已关闭的某个或多个分量载波信号大于预设的阈值信号，则恢复对应所关闭的分量载波信号进行数据业务。
图7是根据本发明可选实施例的载波处理方法的流程图，如图7所示，该流程包括如下步骤：
步骤S701：载波聚合终端开启运营商数据业务；
步骤S702：在检测运营商数据业务开启时，同时设置载波聚合移动终端弱信号状态的阈值；
步骤S703：实时检测载波聚合终端各分量载波信号的强度S1，S2…Sn；
步骤S704：根据所检测的各分量载波的信号强度S1，S2…Sn与所预设的弱信号阈值S进行对比，判断各分量载波是否在弱信号区域；
步骤S705：根据S1，S2…Sn与阈值S对比的结果，进行弱信号状态分量载波的一个处理。如果S1>S，S2>S…Sn>S，其中所有分量载波都不在弱信号状态，终端则按照默认的载波聚合网络进行数据任务；如果S1<S，S2<S…Sn<S，其中所有分量载波都在弱信号状态，终端则关闭所有分量载波聚合的数据任务。如果其中有一个或多个分量载波m在弱信号区域，则关掉在弱信号状态的m个分量载波的数据链路，用余下的n-m个分量载波进行数据任务。
例如：如果用户使用三载波聚合终端，当开启运营商数据下载或者上传业务，终端就会实时的对它的三个分量载波的信号强度检测并进行上报S1，S2，S3，然后对上报的S1，S2，S3与终端预设的弱信号强度阈值S进行对比，如果说三个分量载波S1，S2，S3的信号强度都大于阈值S，即各分量载波信号都比较好的情况，终端则会进行正常的三载波聚合下载；如果三个分量载波S1，S2，S3的信号强度都小于阈值S，则三个分量载波都处于弱信号状态，则终端则会关闭所有载波链路不进行数据业务；如果S1>S，S2>S，S3<S，即1分量载波和2 分量载波信号强度都比较好，3分量载波处于弱信号状态，此时根据上报的情况，终端会关闭3分量载波所工作的链路，只进行1分量载波和2分量载波聚合的数据业务；以此类推，同样其他组合情况与此类似。
更具体的，假设S＝-115dBm，在进入某小区内终端检测到的S1＝-100dBm，S2＝-108dBm，S3＝-95dBm，从S1，S2，S3与阈值S的大小对比可以判断分量载波1和分量载波3信号情况良好，而分量载波2处在弱信号状态下，此时终端根据判断结果关掉分量载波2的链路，只对分量载波1和分量载波3聚合进行数据业务。然后如果测试到S2的信号变好，等到大于-115dBm时，则恢复分量载波3的聚合进行数据业务。
本发明可选实施例还提供了一种弱信号状态下载波的使用的载波聚合装置，图8是根据本发明可选实施例的载波聚合装置的结构示意图，如图8所示，该装置包括：设置模块，第一通信模块，第二通信模块，…第n通信模块。该载波聚合装置可以是内置于移动终端中的软件单元、硬件单元或是软硬件结合的单元。其模块的功能描述如下：
设置模块：设置为设置载波聚合终端弱信号的一个判断标准，设置一个阈值。
第一通信模块：设置为对载波聚合中第一分量载波信号的控制与处理；
第二通信模块：设置为对载波聚合中第二分量载波信号的控制与处理；
….
第n通信模块：设置为对载波聚合中第n分量载波信号的控制与处理；
可选地，每个通信模块中可以包括检测模块，判断模块，控制模块，其中：
检测模块：当载波聚合终端开启运营商数据业务(no wifi)时，设置为自动检测每个分量载波的接收信号强度；
判断模块：设置为对每个分量载波的接收信号强度与所预设的弱信号阈值进行比较；判断各分量载波信号是否处于弱信号状态；
控制模块：根据所对比判断的结果，对分量载波信号进行相对应的处理。如果分量载波信号强度比所设阈值大，则所对应的分量载波链路正常工作；如果分量载波信号强度比所设阈值小也就是说处于弱信号状态，则关闭相对应的载波链路。
上述载波聚合装置用于实现上述载波处理方法。
其中，设置模块在检测运营商数据业务开启时，会设置载波聚合移动终端弱信号状态的阈值。检测模块会实时的检测载波聚合终端各分量载波信号的强度S1，S2…Sn，并上报给判断模块；判断模块则根据检测模块所上报的信号强度S1，S2…Sn，用它门来与所预设的弱信号阈值S进行对比，判断各分量载波是否在弱信号区域，并进行通报给控制模块；控制模块则根据判断模块所通报的结果进行各分量载波的处理。处理原则是关闭所对应的弱信号分量载波链路，开启大于弱信号阈值的分量载波链路。
综上所述，通过本发明的上述实施例和可选实施例，在弱信号状态下，载波聚合终端根据前端的上报情况，关闭相应分量载波工作链路的方法，可以达到降低功耗，提升用户体验的目的，增强产品市场竞争力。
工业实用性：通过上述描述可知，本发明解决了载波聚合的用户设备耗电量高的问题，降低了载波聚合的用户设备的耗电量。
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可选实施例而已，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。
