具体实施方式
本发明实施例提供了一种网络侧设备、UE及功率调整的方法，用于在UE的发射功率值受限时，对控制信道发射功率值和数据信道发射功率值进行调整，以保证UE的覆盖性能。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例描述的各种技术可用于各种通信系统，例如全球移动通信(GSM，global system for mobile communication)等2G通信系统，宽带码分多址(WCDMA，wideband code division multiple access)，时分同步码分多址(TD-SCDMA，time division-synchronization code division multiple access)等3G通信系统，长期演进(LTE，long-term evolution)通信系统及其后续演进系统等下一代通信系统。

处理器101，用于获取用户设备UE的控制信道的第一发射功率值和数据信道的第二发射功率值，当所述第一发射功率值与所述第二发射功率值之和为所述UE的最大发射功率值，且所述第一发射功率值不在预置的功率范围内或所述第一发射功率值与所述最大发射功率值的比值不在预置比值范围内时，生成第一控制消息，，所述预置的功率范围为所述最大发射功率值与所述预置比值范围的乘积，所述第一控制消息用于指示所述UE将所述控制信道的发射功率值降低，且降低后的所述控制信道的发射功率值在所述预置功率范围内或与所述最大发射功率值的比值在所述预置比值范围内。
可以理解的是，网络侧设备可以通过处理器101对接收到的第一发射功率值和第二发射功率进行计算，并当计算结果为UE的最大发射功率值时，该处理器101可以利用预置的比值范围，实现对该第一发射功率值的调整，具体可以包括如下两种方式：
一、处理器101将该最大发射功率值与预置的比值范围相乘得到一个功率值范围，再将该第一发射功率值与该功率值范围进行比对，从而判断该第一发射功率值是否在该功率值范围内，如果是，则结束流程，如果否，则该网络侧设备通过该处理器101生成第一控制消息，该第一控制消息用于指示UE降低第一发射功率值，使降低后的该第一发射功率值在该功率值范围内。
二、该处理器101可以计算该第一发射功率值与最大发射功率值的比值范围，然后将计算得到该比值范围与预置的比值范围进行比对，从而判断该比值范围是否在预置的比值范围内，如果是，则结束流程，如果否，则该处理器101生成第一控制信息，该第一控制信息用于指示UE降低该第一发射功率值，使降低后的该第一发射功率值与最大发射功率值的比值在该预置比值范围内。
需要说明的是，使降低后的第一发射功率值，在最大发射功率值与预置比值范围乘积的范围内或所述第一发射功率值与所述最大发射功率值的比值在预设比值范围内，可以避免因控制信道发射值过低而发生控制信道失步，从而影响UE的覆盖性能。
需要说明的是，本发明实施例中，通过使降低后的第一发射功率值在所述最大发射功率值的预置比值范围内或使所述第一发射功率值与所述最大发射 功率值的比值在预设比值范围内，从而控制对第一发射功率值的调整，以保证UE的覆盖性能，在实际应用中，还可以使降低后的该第一发射功率值在预置的范围内，或者使提高后的第二发射功率值与最大发射功率值的比值在预置比值范围内，或者使提高后的第二发射功率值与最大发射功率值比值，在预置的比值范围内，具体此处不作限定。
可以理解的是，该UE按照接收到该第一控制消息，将第一发射功率值降低，在UE的发射功率维持在最大值时，可以使第二发射功率值得到提高，从而起到提高UE覆盖性能的作用。
需要说明的是，该预置的比值范围可以是预先配置在该网络侧设备中的，也可以是该网络侧设备按照控制策略预先生成的，具体此处不作限定。
发送器102，用于向所述UE发送所述第一控制消息。
可选地，该处理器101还用于对接收到的通知消息进行分析，获取UE的BLER值，当判断出控制信道的发射功率值和数据信道的发射功率值小于最大发射功率值时，该处理器101生成第二控制消息。
可以理解的是，网络侧设备的处理器101可以从UE发送的业务请求消息中获取数传块错率(Block Error Rate，BLER)值，该BLER值用于表示数据传输质量，数据信道的发射功率值可以影响该BLER值，也就是说，可以通过BLER值实现对UE的发射功率的调整。
需要说明的是，UE中预设有第一发射功率值与第二发射功率值的正比例对应关系，当网络侧设备的处理器101判断出第一发射功率值和第二发射功率值之和小于最大发射功率值时，该处理器101可以通过调整第一发射功率值，对UE的发射功率值进行控制，具体地，该处理器101可以根据获取到的BLER值，从而生成用于调整UE第一发射功率值的第二控制消息。
发送器102，还用于向所述UE发送所述第二控制消息，以使得所述UE根据所述第二控制消息调整所述第一发射功率值，并根据预置的所述第一发射功率值与所述第二发射功率值的对应关系，调整所述第二发射功率值。
可以理解的是，当处理器101获取到的BLER低时，该处理器101生成用于降低第一发射功率值的第二控制消息，然后使UE按照该第二控制信息和预置的正比例关系，将第二发射功率值降低，从而节约UE的发射功率值；当处 理器101获取到的BLER高时，该处理器101生成用于提高第一发射功率值的第二控制消息，然后使UE按照该第二控制消息和预置的正比例关系，将第二发射功率值提高，从而增加UE的发射功率。
此外，本发明实施例中，当UE的发射功率达到最大值时，网络侧设备的处理器101通过预置的比值范围，生成第一控制消息，从而使UE降低控制信道的发射功率，以达到保证UE覆盖性能的目的，在实际应用中，还可以对UE的功能进行升级，使UE可以按照第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)Release 8版本的协议，获取络侧设备提供的控制信道发射功率值与最大发射功率值的最优功率比例，从而实现对数据信道的发射功率值和控制信道的发射功率值进行调整，使得当UE受限时，保证UE的覆盖性能。
本发明实施例中，网络侧设备通过接收器接收UE发送的通知消息，当该网络侧设备判断出UE的发射功率受限时，该网络侧设备通过处理器生成第一控制消息，通过该第一控制消息指示UE对该控制信道的发射功率值进行降低，从而使得数据信道的发射功率能够升高，进而使得在降低对UE的功能要求的同时，保证UE的覆盖性能。
上面实施例中，网络侧设备的处理器判断控制信道的发射功率值是否在最大发射功率值的预置比值范围内，在实际应用中，该处理器在进行判断之前，可以确定该比值范围的，下面对处理器确定该比值范围进行描述，请继续参阅图2，本发明实施例中网络侧设备200的另外一个实施例包括：
接收器201，用于接收UE发送的通知消息，所述通知消息包含控制信道的第一发射功率值和数据信道的第二发射功率值。
需要说明的是，网络侧设备通过接收器201周期性或非周期性地接收用户设备UE通过发送器发送的通知消息，该通知消息中携带有UE的发射功率值，该UE的发射功率值包括控制信道的发射功率值和数据信道发射功率值。
可选地，该处理器202在接收UE发送的通知消息之后，还用于确定该控制信道发射功率值与该最大发射功率值的比值范围。
可以理解的是，当UE在网络侧设备的远端移动，UE的发射功率值随之增大，直到UE的发射功率受限时，网络侧设备的处理器202确定此时UE的 发射功率值为最大发射功率值，并确定控制信道失步的功率值与该最大发射功率值的第一比值，和该最大发射功率值与数据信道解调功率值的差值，再确定该差值与该最大功率值的第二比值，将该第一比值和第二比值分别作为比值范围的两个端点值，从而确定该比值范围，比如该处理器202确定UE的最大发射功率为100，控制信道失步的功率值为40，数据信道解调功率值的功率值为20，即当控制信道发生失步时的控制信道发射功率为60，当满足数据信道解调时，控制信道发射功功率值为80，由此可知，控制信道发射功率值占最大发射功率值的比值范围为60％～80％。
其中，随着UE的控制信道发射功率值减小，控制信道发生失步的概率增大，当减小到一定值时，控制信道发生失步，网络侧设备将此时的控制信道的发射功率值记录为控制信道失步的功率值，随着UE的数据信道发射功率值减小，网络侧设备无法正确解调UE发送的业务请求消息中数据包的概率增加，当减小到一定值时，网络侧设备将无法对UE发送的业务请求消息进行解调，该网络侧设备将此时的数据信道发射功率值记录为数据信道解调功率值。
处理器202，用于获取用户设备UE的控制信道的第一发射功率值和数据信道的第二发射功率值，当所述第一发射功率值与所述第二发射功率值之和为所述UE的最大发射功率值，且所述第一发射功率值不在预置的功率范围内或所述第一发射功率值与所述最大发射功率值的比值不在预置比值范围内时，生成第一控制消息，所述预置的功率范围为所述最大发射功率值与所述预置比值范围的乘积，所述第一控制消息用于指示所述UE将所述控制信道的发射功率值降低，且降低后的所述控制信道的发射功率值在所述预置的功率范围内或与所述最大发射功率值的比值在所述预置比值范围内。
当UE在网络侧设备的远端移动时，为了防止因数据信道无法正确解调和控制信道发生失步，而导致的UE覆盖性能降低，需要提升该UE的第二发射功率值和第一发射功率值，使UE的发射功率值增加，但当网络侧设备识别出UE的第一发射功率值和第二发射功率值达到UE的最大发射功率值时，无法继续再提升第一发射功率值和第二发射功率值，此时该网络侧设备的处理器202可以按照该预置的比值范围，对该第一发射功率值进行调整，包括至少如下两种实现方式：
一、处理器101将该最大发射功率值与预置的比值范围相乘得到一个功率值范围，再将该第一发射功率值与该功率值范围进行比对，从而判断该第一发射功率值是否在该功率值范围内，如果是，则结束流程，如果否，则该网络侧设备通过该处理器101生成第一控制消息，该第一控制消息用于指示UE降低第一发射功率值，使降低后的该第一发射功率值在该功率值范围内，比如网络侧设备中配置有UE的最大发射功率值为100，并且配置有UE的第一发射功率值与该最大发射功率值的比值为范围为50％～60％，计算该最大发射功率值100与比值范围50％～60的乘积，得到功率值范围为50～60，当该网络侧设备获取到UE上报的第一发射功率为70，第二发射功率为30时，该网络侧设备首先判断出该第一发射功率值与第二发射功率值等于最大发射功率值，并判断出该第一发射功率值70大于该功率值范围的最大值60，超出该范围，因此网络侧设备的处理器202生成用于指示该UE降低第一发射功率的第一控制消息，使该UE降低该第一发射功率值，并提升第二发射功率，比如UE将第一发射功率从70降低为55，使得该第一发射功率值在该预置比值范围与该最大发射功率值的乘积50～60的范围内，同时将发射功率从30提升为45，使得第一发射功率值与第二发射功率值仍然为100。
二、该处理器101可以计算该第一发射功率值与最大发射功率值的比值范围，然后将计算得到该比值范围与预置的比值范围进行比对，从而判断该比值范围是否在预置的比值范围内，如果是，则结束流程，如果否，则该处理器101生成第一控制信息，该第一控制信息用于指示UE降低该第一发射功率值，使降低后的该第一发射功率值与最大发射功率值的比值在该预置比值范围内。比如网络侧设备中配置有UE的最大发射功率值为100，并且配置有UE的第一发射功率值与该最大发射功率值的比值为范围为50％～60％，当该网络侧设备获取到UE上报的第一发射功率为70，第二发射功率为30时，该网络侧设备首先判断出该第一发射功率值与第二发射功率值等于最大发射功率值，并计算该第一射功率值70与最大发射功率值100的比值范围为70％，将计算出的该比值范围70％与预置的比值范围50％～60进行比对，可知超出该预置的比值范围，因此网络侧设备的处理器202生成用于指示该UE降低第一发射功率的第一控制消息，使该UE降低该第一发射功率值，并提升第二发射功率，比如 UE将第一发射功率从70降低为55，使得该第一发射功率占总发射功率的55％，在该范围内，同时将发射功率从30提升为45，使得第一发射功率值与第二发射功率值仍然为100。
发送器203，用于向所述UE发送所述第一控制消息。
本发明实施例中，网络侧设备通过接收器接收UE发送的通知消息，当该网络侧设备判断出UE的发射功率受限时，该网络侧设备再判断控制信道的发射功率值是否在最大发射功率值的预置比值范围内之前，还用于确定该控制信道发射功率值与该最大发射功率值的比值范围，使该处理器可以根据该比值范围生成第一控制消息，并通过该第一控制消息指示UE对该控制信道的发射功率值和该数据信道的发射功率值进行调整，从而能在保证UE覆盖性能的同时，无需对UE进行功能升级，从而节约成本。此外，该网络侧设备通过控制信道失步的功率值和数据信道解调的功率值确定的比值范围，可以使控制信道的发射功率值和数据信道的发射功率值达到最优比，从而可以起到提升UE覆盖性能的作用。
上面实施例中对网络侧设备进行了描述，下面对本发明实施例中的UE进行描述，
请参阅图3，本发明实施例中用户设备UE300的一个实施例包括：接收器302和处理器303，可选地，所述UE300还包括发送器301。
发送器301，用于向网络侧设备发送通知消息，所述通知消息包含控制信道的第一发射功率值和数据信道的第二发射功率值。
可以理解的是，用户设备UE的发射功率影响覆盖性能，因此UE需要对发射功率进行合理的控制，比如提高数据信道的发射功率，可以提升UE的覆盖性能，降低控制信道的发射功率，将导致控制信道失步，降低UE的覆盖性能。为了实现UE对发射功率的控制，可以通过UE的发送器301向网络侧设备发送通知消息，从而将UE的发射功率值周期性或非周期性的上报给网络侧设备，该UE的发射功率值包括控制信道的发射功率值和数据信道的发射功率值。
接收器302，用于接收所述网络侧设备发送的第一控制消息，所述第一控制消息为所述网络侧设备在判断出所述第一发射功率值与所述第二发射功率 值之和为UE的最大发射功率值，且所述第一发射功率值不在预置的功率范围内或所述第一发射功率值与所述最大发射功率值不在所述预置比值范围内时，发送的消息，所述预置的功率范围为所述最大发射功率值与预置比值范围的乘积。
当UE在网络侧设备的远端移动时，即UE在网络侧设备的小区边缘移动时，为了防止因数据信道无法正确调解和控制信道发生失步，而导致的UE覆盖性能降低，需要提升该UE的第二发射功率值和第一发射功率值，使UE的发射功率增加，但当第一发射功率和第二发射功率的和达到UE的最大发射功率值时，该UE无法继续再提升第一射功率和第二发射功率，即此时该UE的发射功率受限，该UE的接收器302可以接收网络侧设备发送的第一控制消息。
需要说明的是，网络侧设备可以获取UE的第二发射功率和第一发射功率，并判断该第二发射功率值和第一发射功率值之和是否达到最大发射功率值，当判断该第二发射功率值和第一发射功率值之和达到最大发射功率值时，该网络侧设备可以继续判断该第二发射功率值和第一发射功率值是否在比值范围内，当判断该第二发射功率值和第一发射功率值在比值范围内时，可以向UE发送第一控制消息。
可选地，该网络侧设备中的比值范围可以是预先设置好的，也可以是该网络侧设备控制策略预先生成的，具体此处不作限定。
需要说明的是，该预置比例范围为UE的发射功率达到最大值时，为了保证该UE的覆盖性能，网络侧设备获取到的第一发射功率值占UE的最大发射功率值的比例范围。
处理器303，用于根据所述接收器接收到第一控制消息，降低所述第一发射功率值，以使得所述降低后的第一发射功率值在预置功率范围内，或与所述最大发射功率值的比值在预设比值范围内。
可以理解的是，在UE的发射功率维持在最大值时，若该UE按照接收到该第一控制消息，将第一发射功率值降低，可以使第二发射功率值得到提高，从而起到提高UE覆盖性能的作用。
需要说明的是，处理器303可以使降低后的第一发射功率值，在最大发射功率值与预置比值范围乘积的范围内或所述第一发射功率值与所述最大发射 功率值的比值在预设比值范围内，以避免降低后的控制信道发射值过低而发生控制信道失步，从而影响UE的覆盖性能。
需要说明的是，本发明实施例中，UE的处理器303通过使降低后的第一发射功率值在所述最大发射功率值的预置比值范围内或所述第一发射功率值与所述最大发射功率值的比值在预设比值范围内，从而实现对第一发射功率值的调整，以提高数据信道的发射功率值，在实际应用中，还可使降低后的该第一发射功率值与最大发射功率值的比值，在预置的比值范围内或者使降低后的该第一发射功率值在预置的范围内，或者使提高后的第二发射功率值与最大发射功率值的比值在预置比值范围内，或者使提高后的第二发射功率值在最大发射功率值，具体此处不作限定。
可选地，在上面实施例中，当UE在网络侧设备的近端移动时，即UE的发射功率未达到最大值时，该UE的控制信道发射功率值与数据信道发射功率值成存在固定的正比例对应关系，此时UE可以通过该接收器302接收该网络侧设备发送的第二控制消息，并使处理器303根据该第二控制消息对控制信道的发射功率值进行调整，再根据该对应关系对数据信道发射功率值进行相应的调整。
可以理解的是，网络侧设备可以从UE发送的业务请求消息中获取数传块错率(Block Error Rate，BLER)值，该BLER值用于表示数据传输质量，数据信道的发射功率值可以影响该BLER值，因此在BLER值满足数据正常传输时，可以通过对BLER值的调整，实现对数据信道发射功率值的调整。
需要说明的是，UE中预置有数据信道发射功率值与控制信道发射功率值的正比例对应关系，通过BLER值，实现对数据信道发射功率值和控制信道发射功率值的调整的具体过程可以为：网络侧设备根据BLER值生成第二控制消息，并向UE发送该消息，该UE按照第二控制消息进行调整。
可以理解的是，该网络侧设备中可以将获取到的BLER值与预置的BLER阈值进行比对，当判断出获取到的BLER值大于该预置的阈值时，生成第二控制消息，该第二控制消息用于指示UE提高控制信道的发射功率值，从而增加UE的发射功率值；当判断出获取到的BLER值小于预置的阈值时，该第二控制消息用于指示UE降低控制信道的发射功率值，从而降低UE的发射功率值， 比如网络侧设备中保存的BLER值为0.3，当UE向网络侧设备发送的100个业务数据包时，网络侧设备对UE发送的业务数据包逐一进行解调分析，发现中有20个业务数据包无法解调或解调错误，则得到BLER值为0.2，网络侧设备将得到的BLER值与保存的BLER值进行比对，发现得到的BLER值更小，则该网络侧设备生成第二控制消息，用于指示UE降低数据信道的发射功率值。
其中，该BLER值用于表示数据的传输质量，BLER值越低表示数据传输质量越好，BLER值越高表示数据传输质量越差，网络侧设备中的BLER值可以根据实际需要进行设定。
本发明实施例中，当UE向网络侧设备的远端移动，且UE的发射功率受限时，该UE通过接收器接收网络侧设备发送的第一控制消息，该UE的处理器可以根据该第一控制消息对控制信道的发射功率值和数据信道的发射功率值进行调整，使该控制信道的功率在最大发射功率的预置范围内，并且该控制信道的发射功率和数据信道的发射功率之和等于该最大发射功率。相对于现有技术而言，无需对UE进行功能升级，即可在UE功能受限时，保证UE的覆盖性能，起到节约成本的目的；此外，当UE在网络侧设备的近端时，此时UE的发射功率不受限，该UE通过接收器接收网络侧设备发送的第二控制消息，该UE的处理器再根据该第二控制消息对控制信道的发射功率值和数据信道的发射功率值，可以起到在保证UE数据传输质量的同时，节约该UE的发射功率值。
上面实施例中对本发明的网络侧设备进行了描述，下面对网络侧设备对应的方法实施例进行描述。
请参阅图4，本发明实施例中一种功率调整的方法，包括：
401、网络侧设备获取用户设备UE的控制信道的第一发射功率值和数据信道的第二发射功率值。
可以理解的是，网络侧设备能够从UE中周期性或非周期性的获取UE的发射功率，其中，该UE的发射功率包括控制信道发射功率和数据信道发射功率。
402、判断所述第一发射功率值与所述第二发射功率值之和是否为所述UE的最大发射功率值，若否，则步骤403，若是则执行步骤404。
可以理解的是，网络侧设备可以对接收到的第一发射功率值和第二发射功率的和值进行计算，并将计算结果与预置的UE的最大发射功率值进行比对，从而判断第一发射功率值与所述第二发射功率值之和是否为所述UE的最大发射功率值。
403、结束流程。
404、继续判断所述第一发射功率值是否不在预置的功率范围内，若否，则执行步骤405，若是，则执行步骤406。
可以理解的是，当计算结果为UE的最大发射功率值时，该网络侧设备可以利用预置的比值范围对第一发射功率值继续进行判断。
其中，网络侧设备可以将该最大发射功率值与预置的比值范围相乘得到一个功率值范围，再将该第一发射功率值与该功率值范围进行比对，从而判断该第一发射功率值是否在该功率值范围内，如果否，则执行步骤405，如果是，执行则步骤406。
可选地，该网络侧设备还可以判断所述第一发射功率值与所述最大发射功率值的比值是否不在预置比值范围内，具体地，该网络侧设备可以计算该第一发射功率值与最大发射功率值的比值范围，然后将计算得到该比值范围与预置的比值范围进行比对，从而判断该比值范围是否在预置的比值范围内。
可选地，该网络侧设备还可以判断第一发射功率值是否在预置的范围内，或者判断第二发射功率值与最大发射功率值的比值，是否在预置比值范围内，或者判断第二发射功率值与在最大发射功率值的比值，是否在预置的比值范围内，具体此处不作限定。
需要说明的是，该预置的比值范围可以是预先配置在该网络侧设备中的，也可以是该网络侧设备按照控制策略预先生成的，具体此处不作限定。
405、结束流程。
406、该网络侧设备生成第一控制消息，该第一控制消息用于指示UE降低第一发射功率值，使降低后的该第一发射功率值在该功率值范围内。
需要说明的是，使降低后的第一发射功率值，在最大发射功率值与预置比值范围乘积的范围内，可以避免因控制信道发射值过低而发生控制信道失步，从而影响UE的覆盖性能。
需要说明的是，本发明实施例中，通过使降低后的第一发射功率值在所述最大发射功率值的预置比值范围内，从而控制对第一发射功率值的调整，以保证UE的覆盖性能，在实际应用中，还可使第一发射功率值与所述最大发射功率值的比值在预设比值范围内，或者使降低后的该第一发射功率值与最大发射功率值的比值，在预置的比值范围内或者使降低后的该第一发射功率值在预置的范围内，或者使提高后的第二发射功率值与最大发射功率值的比值在预置比值范围内，或者使提高后的第二发射功率值在最大发射功率值，具体此处不作限定。
407、所述网络侧设备向所述UE发送所述第一控制消息。
可以理解的是，在网络侧设备生成第一控制消息之后，可以向UE发送该第一控制消息。
可选地，在本实施例中的步骤403之后还包括步骤404和步骤405。
408、所述网络侧设备从所述UE发送的业务请求消息中获取BLEER值，并当所述第一发射功率与所述第二发射功率之和小于所述最大发射功率时，根据所述BLEER值生成第二控制消息。
可以理解的是，网络侧设备的处理器101可以从UE发送的业务请求消息中获取数传块错率(Block Error Rate，BLER)值，该BLER值用于表示数据传输质量，数据信道的发射功率值可以影响该BLER值，也就是说，可以通过BLER值实现对UE的发射功率的调整。
需要说明的是，UE中预设有第一发射功率值与第二发射功率值的正比例对应关系，当网络侧设备判断出第一发射功率值和第二发射功率值之和小于最大发射功率值时，该网络侧设备可以通过调整第一发射功率值，对UE的发射功率值进行控制，具体地，该网络侧设备可以根据获取到的BLER值，从而生成用于调整UE第一发射功率值的第二控制消息。
409、所述网络侧设备向所述UE发送所述第二控制消息，以使得所述UE根据所述第二控制消息调整所述第一发射功率值，并根据预置的所述第一发射功率值与所述第二发射功率值的对应关系，调整所述第二发射功率值。
上面实施例中，网络侧设备判断控制信道的发射功率值是否在最大发射功率值的预置比值范围内，在实际应用中，该网络侧设备在进行判断之前，可以 确定该比值范围的，下面对网络侧设备确定该比值范围进行描述。
可以理解的是，当网络侧设备获取到的BLER低时，该网络侧设备生成用于降低第一发射功率值的第二控制消息，然后使UE按照该第二控制信息和预置的正比例关系，将第二发射功率值降低，从而节约UE的发射功率值；当网络侧设备获取到的BLER高时，该网络侧设备生成用于提高第一发射功率值的第二控制消息，然后使UE按照该第二控制消息和预置的正比例关系，将第二发射功率值提高，从而增加UE的发射功率。
此外，本发明实施例中，当UE的发射功率达到最大值时，网络侧设备通过预置的比值范围，生成第一控制消息，从而使UE降低控制信道的发射功率，以达到保证UE覆盖性能的目的，在实际应用中，还可以对UE的功能进行升级，使UE可以按照第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)Release 8版本的协议，获取络侧设备提供的控制信道发射功率值与最大发射功率值的最优功率比例，从而实现对数据信道的发射功率值和控制信道的发射功率值进行调整，使得当UE受限时，保证UE的覆盖性能。
本发明实施例中，网络侧设备接收UE发送的通知消息，当该网络侧设备判断出UE的发射功率受限时，该网络侧设备生成第一控制消息，通过该第一控制消息指示UE对该控制信道的发射功率值进行降低，从而使得数据信道的发射功率能够升高，进而使得在降低对UE的功能要求的同时，保证UE的覆盖性能。
请继续参阅图3，本发明实施例中一种功率调整方法的另外一个实施例包括：
501、网络侧设备获取用户设备UE的控制信道的第一发射功率值和数据信道的第二发射功率值。
需要说明的是，网络侧设备周期性或非周期性地接收用户设备UE通过发送器发送的通知消息，该通知消息中携带有UE的发射功率值，该UE的发射功率值包括控制信道的发射功率值和数据信道发射功率值。
可选地，在本实施例的步骤501之后，还包括步骤502。
502、所述网络侧设备确定所述比值范围。
可以理解的是，当UE在网络侧设备的远端移动，UE的发射功率值随之 增大，直到UE的发射功率受限时，网络侧设备确定此时UE的发射功率值为最大发射功率值，并确定控制信道失步的功率值与该最大发射功率值的第一比值，和该最大发射功率值与数据信道解调功率值的差值，再确定该差值与该最大功率值的第二比值，将该第一比值和第二比值分别作为比值范围的两个端点值，从而确定该比值范围，比如网络侧设备确定UE的最大发射功率为100，控制信道失步的功率值为40，数据信道解调功率值的功率值为20，即当控制信道发生失步时的控制信道发射功率为60，当满足数据信道解调时，控制信道发射功功率值为80，由此可知，控制信道发射功率值占最大发射功率值的比值范围为60％～80％。
其中，随着UE的控制信道发射功率值减小，控制信道发生失步的概率增大，当减小到一定值时，控制信道发生失步，网络侧设备将此时的控制信道的发射功率值记录为控制信道失步的功率值，随着UE的数据信道发射功率值减小，网络侧设备无法正确解调UE发送的业务请求消息中数据包的概率增加，当减小到一定值时，网络侧设备将无法对UE发送的业务请求消息进行解调，该网络侧设备将此时的数据信道发射功率值记录为数据信道解调功率值。
503、判断所述第一发射功率值与所述第二发射功率值之和是否为所述UE的最大发射功率值，若否，则步骤504，若是则执行步骤505。
504、结束流程。
505、继续判断所述第一发射功率值是否不在所述预置的功率值范围内，若否，则执行步骤506，若是，则执行步骤507。
506、结束流程。
507、所述网络侧设备生成第一控制消息，所述第一控制消息用于指示所述UE将所述控制信道的发射功率降低，且降低的所述控制信道的发射功率与所述最大发射功率值的比值在所述预置比值范围内。
508、所述网络侧设备向所述UE发送所述第一控制消息。
可选地，在本实施例中的步骤508之后还包括步骤509和步骤510。
509、所述网络侧设备从所述UE发送的业务请求消息中获取BLEER值，并当所述第一发射功率与所述第二发射功率之和小于所述最大发射功率时，根据所述BLEER值生成第二控制消息。
510、所述网络侧设备向所述UE发送所述第二控制消息，以使得所述UE根据所述第二控制消息调整所述第一发射功率值，并根据预置的所述第一发射功率值与所述第二发射功率值的对应关系，调整所述第二发射功率值。
本实施中步骤503至步骤510执行方法，可参考图4对应的实施例，具体此处不再赘述。
本发明实施例中，网络侧设备接收UE发送的通知消息，当该网络侧设备判断出UE的发射功率受限时，该网络侧设备再判断控制信道的发射功率值是否在最大发射功率值的预置比值范围内之前，还用于确定该控制信道发射功率值与该最大发射功率值的比值范围，使该网络侧设备可以根据该比值范围生成第一控制消息，并通过该第一控制消息指示UE对该控制信道的发射功率值和该数据信道的发射功率值进行调整，从而能在保证UE覆盖性能的同时，无需对UE进行功能升级，从而节约成本。此外，该网络侧设备通过控制信道失步的功率值和数据信道解调的功率值确定的比值范围，可以使控制信道的发射功率值和数据信道的发射功率值达到最优比，从而可以起到提升UE覆盖性能的作用。
上面实施例中对本发明的用户设备UE进行了描述，下面从UE对应的方法实施例进行描述。
请参阅图6，本发明实施例中，一种功率调整方法的一个实施例包括：
601、UE向网络侧设备发送通知消息，所述通知消息包含控制信道的第一发射功率值和数据信道的第二发射功率值。
可以理解的是，用户设备UE的发射功率影响覆盖性能，因此UE需要对发射功率进行合理的控制，比如提高数据信道的发射功率，可以提升UE的覆盖性能，降低控制信道的发射功率，将导致控制信道失步，降低UE的覆盖性能。为了实现UE对发射功率的控制，可以通过UE向网络侧设备发送通知消息，从而将UE的发射功率值周期性或非周期性的上报给网络侧设备，该UE的发射功率值包括控制信道的发射功率值和数据信道的发射功率值。
602、所述UE接收所述网络侧设备发送的第一控制消息，所述第一控制消息为所述网络侧设备在判断出所述第一发射功率值与所述第二发射功率值之和为所述UE的最大发射功率值，且所述第一发射功率值不在预置的比值范 围内或与所述最大发射功率值不在所述预置比值范围内时，发送的消息，所述预置的功率范围为所述最大发射功率值与所述预置比值范围的乘积。
当UE在网络侧设备的远端移动时，即UE在网络侧设备的小区边缘移动时，为了防止因数据信道无法正确调解和控制信道发生失步，而导致的UE覆盖性能降低，需要提升该UE的第二发射功率值和第一发射功率值，使UE的发射功率增加，但当第一发射功率和第二发射功率的和达到UE的最大发射功率值时，该UE无法继续再提升第一射功率和第二发射功率，即此时该UE的发射功率受限，该UE可以接收网络侧设备发送的第一控制消息。
需要说明的是，网络侧设备可以获取UE的第二发射功率和第一发射功率，并判断该第二发射功率值和第一发射功率值之和是否达到最大发射功率值，当判断该第二发射功率值和第一发射功率值之和达到最大发射功率值时，该网络侧设备可以继续判断该第二发射功率值和第一发射功率值是否在比值范围内，当判断该第二发射功率值和第一发射功率值在比值范围内时，可以向UE发送第一控制消息。
可选地，该网络侧设备中的比值范围可以是预先设置好的，也可以是该网络侧设备控制策略预先生成的，具体此处不作限定。
需要说明的是，该预置比例范围为UE的发射功率达到最大值时，为了保证该UE的覆盖性能，网络侧设备获取到的第一发射功率值占UE的最大发射功率值的比例范围。
603、所述UE根据所述接收器接收到第一控制消息，降低所述第一发射功率值，以使得所述第一发射功率值在预置比值范围内或与所述最大发射功率值的比值在预设比值范围内。
可以理解的是，在UE的发射功率维持在最大值时，若该UE按照接收到该第一控制消息，将第一发射功率值降低，可以使第二发射功率值得到提高，从而起到提高UE覆盖性能的作用。
需要说明的是，UE可以使降低后的第一发射功率值，在最大发射功率值与预置比值范围乘积的范围内或所述第一发射功率值与所述最大发射功率值的比值在预设比值范围内，以避免降低后的控制信道发射值过低而发生控制信道失步，从而影响UE的覆盖性能。
需要说明的是，本发明实施例中，UE通过使降低后的第一发射功率值在所述最大发射功率值的预置比值范围内或所述第一发射功率值与所述最大发射功率值的比值在预设比值范围内，从而实现对第一发射功率值的调整，以提高数据信道的发射功率值，在实际应用中，还可使降低后的该第一发射功率值与最大发射功率值的比值，在预置的比值范围内或者使降低后的该第一发射功率值在预置的范围内，或者使提高后的第二发射功率值与最大发射功率值的比值在预置比值范围内，或者使提高后的第二发射功率值在最大发射功率值，具体此处不作限定。
可选地，在本实施例中的步骤603之后，还包括步骤604和步骤605。
604、当所述网络侧设备判断出所述第一发射功率值与所述第二发射功率值之和小于最大发射功率值时，所述UE接收所述网络侧设备根据BLER值发送的第二控制消息，所述BLER值为所述网络侧设备从所述UE发送的业务请求消息中获取到的用于指示数据传输质量的值。
可以理解的是，网络侧设备可以从UE发送的业务请求消息中获取数传块错率(Block Error Rate，BLER)值，该BLER值用于表示数据传输质量，数据信道的发射功率值可以影响该BLER值，因此在BLER值满足数据正常传输时，可以通过对BLER值的调整，实现对数据信道发射功率值的调整。
需要说明的是，UE中预置有数据信道发射功率值与控制信道发射功率值的正比例对应关系，通过BLER值，实现对数据信道发射功率值和控制信道发射功率值的调整的具体过程可以为：网络侧设备根据BLER值生成第二控制消息，并向UE发送该消息，该UE按照第二控制消息进行调整。
605、所述UE根据所述接收器接收到的第二控制消息调整所述第一发射功率值，并根据预置的所述第一发射功率值和所述第二发射功率值的对应关系，调整所述第二发射功率值。
可以理解的是，该网络侧设备中可以将获取到的BLER值与预置的BLER阈值进行比对，当判断出获取到的BLER值大于该预置的阈值时，生成第二控制消息，该第二控制消息用于指示UE提高控制信道的发射功率值，从而增加UE的发射功率值；当判断出获取到的BLER值小于预置的阈值时，该第二控制消息用于指示UE降低控制信道的发射功率值，从而降低UE的发射功率值， 比如网络侧设备中保存的BLER值为0.3，当UE向网络侧设备发送的100个业务数据包时，网络侧设备对UE发送的业务数据包逐一进行解调分析，发现中有20个业务数据包无法解调或解调错误，则得到BLER值为0.2，网络侧设备将得到的BLER值与保存的BLER值进行比对，发现得到的BLER值更小，则该网络侧设备生成第二控制消息，用于指示UE降低数据信道的发射功率值。
其中，该BLER值用于表示数据的传输质量，BLER值越低表示数据传输质量越好，BLER值越高表示数据传输质量越差，网络侧设备中的BLER值可以根据实际需要进行设定。
本发明实施例中，当UE向网络侧设备的远端移动，且UE的发射功率受限时，该UE接收网络侧设备发送的第一控制消息，该UE的可以根据该第一控制消息对控制信道的发射功率值和数据信道的发射功率值进行调整，使该控制信道的功率在最大发射功率的预置范围内，并且该控制信道的发射功率和数据信道的发射功率之和等于该最大发射功率。相对于现有技术而言，无需对UE进行功能升级，即可在UE功能受限时，保证UE的覆盖性能，起到节约成本的目的；此外，当UE在网络侧设备的近端时，此时UE的发射功率不受限，该UE接收网络侧设备发送的第二控制消息，该UE再根据该第二控制消息对控制信道的发射功率值和数据信道的发射功率值，可以起到在保证UE数据传输质量的同时，节约该UE的发射功率值。
