Description

一种功率确定方法、设备及系统
本申请要求于2017年06月16日提交中国专利局、申请号为201710459417.8、申请名称为“一种功率确定方法、设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信技术领域，尤其涉及一种功率确定方法、设备及系统。
背景技术
第五代移动通信(5th-generation，5G)(又称下一代无线(generation radio，NR))系统采用最为先进的移动通信技术，它能够为移动用户提供更高的带宽和更安全的通信。为了能够与上一代通信系统(如：长期演进(long term evolution，LTE)系统)共存，5G系统可以与LTE系统共享相同的频段资源，例如，如图1所示，LTE系统中的终端(user equipment，UE)利用LTE频分多址(frequency division duplexing，FDD)下行(downlink，DL)载波F2进行下行传输，5G系统中的UE利用时分双工(time division duplexing，TDD)载波F3进行下行传输，而对于上行传输，5G系统中的终端(user equipment，UE)和LTE系统中的UE可以共同利用LTE FDD上行(uplink，UL)载波F1进行上行传输，以此实现频带资源的共享。
但是，由于F1和F3是LTE FDD的一对成对频谱，LTE的UE可以通过承载在F3的LTE下行参考信号测量得到F3的路损，且该路损可以用于F1。而对于5G系统中的UE而言，由于F3只用于传输LTE的信号，5G系统的UE不能识别F3，所以不能通过F3上的参考信号测量得到F1的路损；虽然，F2承载5G的下行参考信息，5G系统中的UE可以通过承载在F2的下行参考信息测量得到F2的路损，但是，由于在5G系统中F1和F2的载频相差较远，F1和F2的路径损耗、穿透损耗不同，所以在F2上测量的路损不能直接用于F1，因此，5G系统中的UE无法获得上行载波F1的路损，进而无法计算出发送上行信号的功率。
发明内容
本发明实施例提供一种功率确定方法、设备及系统，解决了5G系统中如何确定发送上行信号的功率的问题。
为达到上述目的，本发明实施例采用如下技术方案：
第一方面，本发明实施例提供了一种功率确定方法，包括：
终端从网络设备接收第一偏移值，根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率；
其中，第一偏移值根据第一载波的穿透损耗与第二载波的穿透损耗确定，第一载波为终端的上行载波，第二载波为终端的TDD载波或下行载波。
下行信号包括下行参考信号，下行信号的接收功率包括参考信号接收功率(reference signal received power，RSRP)。下行信号还可以包括下行数据信号。
如此，当终端发送上行信号时，考虑到穿透损耗对上行信号的功率的影响，根据与穿透损耗相关的偏移值确定发送上行信号的功率，如此，根据终端的传输环境确定出计算发送上行信号的功率，解决了现有5G系统中无法计算出发送上行信号的功率的问题。
需要说明的是，在本发明实施例中，第一偏移值可以为第一载波的穿透损耗与第二载波的穿透损耗的差值；上行载波可以为：承载终端向网络设备发送的信令或数据的载波，下行载波可以为：承载网络设备向终端发送的数据或信令的载波，TDD载波可以为：在不同的时隙承载终端向网络设备发送的数据或信令、以及网络设备向终端发送的数据或信令的载波。
在本发明实施例中，第一载波可以包含多个子载波，当第一载波包含多个子载波时，根据第一载波的穿透损耗与第二载波的穿透损耗确定出的第一偏移值也可以包含多个与子载波一一对应的值。
结合第一方面，在一种可能的实现方式中，终端在下述几种情况下，终端才根据根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率，如：
当终端在第二载波上接收下行信号的接收功率小于或等于第一门限值时，终端根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率；或者
当终端在第二载波上接收下行信号的路损小于或等于第二门限值时，终端根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率；或者
当终端在第二载波上接收下行信号的RSRP小于或等于第三门限值时，终端根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率。
其中，第一门限值、第二门限值、第三门限值的具体取值可以根据需要进行设置，本发明实施例对此不进行限定。可选的，第一门限值、第二门限值、第三门限值可以由网络设备配置给终端。
第一门限值单位与下行信号接收功率单位对应，当终端测量到的第二载波上接收下行信号的接收功率小于或等于第一门限值时，表示终端和接入网设备间传输条件较差，终端为室内用户；第二门限值与路损单位对应，当终端在第二载波上接收下行信号的路损小于或等于第二门限值时，表示终端和接入网设备间传输条件较差，终端为室内用户；第三门限值单位与下行参考信号的RSRP单位对应，当终端在第二载波上接收下行信号的RSRP小于或等于第三门限值时，表示终端和接入网设备间传输条件较差，终端为室内用户。
此外，在确定终端为室内终端时，包括但不限于上述方式，还可以参照其他实现方式，如：网络设备可以根据终端上报的参考信号接收功率，确定终端为室内终端或室外终端，并将确定结果通知给终端，以便终端根据该通知结果确定根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率。
结合上述可能的实现方式，在一种可能的实现方式中，所述终端根据在所述第二 载波上接收下行信号的接收功率和所述第一偏移值确定在所述第一载波上发送上行信号的功率可以包括：
终端根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率；第二载波的路损为终端根据在第二载波上接收下行信号的接收功率确定的。
结合上述可能的实现方式，在一种可能的实现方式中，终端根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率可以包括：
终端根据第二载波的路损、第一偏移值确定第一载波的路损，并根据第一载波的路损确定在第一载波上发送上行信号的功率。
其中，终端可以通过下述两个方式计算第一载波的路损：
将第二载波的路损、第一偏移值以及第二偏移值相加后的结果作为第一载波的路损；第二偏移值为第一载波的路径损耗和第二载波的路径损耗的差值；或者，
在第二偏移值用于配置第一载波的上行功率控制参数的情况下，终端直接将第二载波的路损和第一偏移值相加后的结果作为第一载波的路损。
在计算出第一载波的路损后，终端可以根据第一载波的路损、网络设备配置的功率控制参数，按照现有功率控制计算公式确定第一载波上发送上行信号的功率，功率的取值单位为dBm。
如此，终端可以参照现有功率控制公式，结合确定出的上行路损计算出上行信号的发送功率，其中，现有功率控制公式如具体实施方式部分所述。
结合第一方面和上述可能的实现方式，在一种可能的实现方式中，终端根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率还可以包括：
终端根据下述公式一或者公式二确定在第一载波上发送上行信号的功率P：
公式一：P＝min{P max,FUNCTION(M,P 0,△,f)+α·PL+offset}，
公式二：P＝min{P max,FUNCTION(M,P 0,△,f)+α·PL+α·offset}，
其中，在公式一和公式二中，offset为第一偏移值；
PL根据第二载波的路损确定，PL为第二载波的路损，或者，PL为第二载波的路损和第二偏移值相加后的结果，第二载波的路损为终端根据在第二载波上接收下行信号的接收功率确定的，第二偏移值为根据第一载波的路径损耗和第二载波的路径损耗确定的；
P max为终端在第一载波的最大发射功率；
FUNCTION(M,P 0,△,f)为上行功率控制中与M,P 0,△,f有关的函数，M为终端在第一载波上发送上行信号占用的资源块数目，P 0为终端从网络设备获取的目标接收功率相关的功率控制参数，△为终端从网络设备获取的编码调制方式相关的功率控制参数，f为终端从网络设备获取的功率命令相关的功率控制参数；
α为终端从网络设备获取的路损补偿相关的功率控制参数。
如此，可以终端可以直接根据第一偏移值计算出发送上行信号的功率，不需要先计算出上行路损，再根据上行路损计算出发送上行信号的功率，降低了终端的计算复杂度。
可选的，在本发明实施例中，针对不同的上行信号，函数FUNCTION(M,P 0,△,f)的表现形式是不同的，例如：对于物理上行共享信道(physical uplink shared channel， PUSCH)，FUNCTION(M,P 0,△,f)为：
10log 10(M PUSCH,c(i))+P O_PUSCH,c(j)+△ TF,c(i)+f c(i)
对于探测参考信号(sounding reference signal，SRS)FUNCTION(M,P 0,△,f)为：
10log 10(M SRS,c)+P O_SRS,c(m)+f SRS,c(i)或者
10log 10(M SRS,c)+P O_PUSCH,c(j)+f c(i)
对于物理上行链路控制信道(physical uplink control channel，PUCCH)FUNCTION(M,P 0,△,f)为：
P 0_PUCCH+h(n CQI,n HARQ,n SR)+△ F_PUCCH(F)+△ TxD(F')+g(i)
其中，上述公式中的i为子帧编号，c为载波编号，P CMAX,c(i),为gNB的最大发射功率，M PUSCH,c(i))为第i个子帧第c个载波上PUSCH的数目，P O_PUSCH,c(j)为目标接收功率，△ TF,c(i)为与调制方式相关的调整量，f c(i)为功率控制因子。
结合第一方面，在一种可能的实现方式中，所述方法还可以包括：
当终端在第二载波上接收下行信号的接收功率大于第一门限值时，或者当终端在第二载波上接收下行信号的路损大于第二门限值时，或者当终端在第二载波上接收下行信号的RSRP大于第三门限值时，终端根据第二载波的路损确定在第一载波上发送上行信号的功率。
如此，当终端测量到的第二载波上接收下行信号的接收功率大于第一门限值时，或者当终端在第二载波上接收下行信号的路损大于第二门限值时，或者当终端在第二载波上接收下行信号的RSRP大于第三门限值时，表示终端和接入网设备间传输条件较好，该终端为室外终端，在计算上行信号的功率时不需要考虑与穿透损耗相关的第一偏移值，提高了发送上行信号的功率的准确性。
结合第一方面和上述可能的实现方式，在一种可能的实现方式中，终端根据第二载波的路损确定在第一载波上发送上行信号的功率可以包括：
终端根据第二载波的路损确定第一载波的路损，并根据第一载波的路损确定第一载波上发送上行信号的功率。
可选的，终端可以将第二载波的路损和第二偏移值相加后的结果作为第一载波的路损；
或者，在第二偏移值用于配置第一载波的上行功率控制参数的情况下，直接将第二载波的路损作为第一载波的路损。
在计算出第一载波的路损后，终端可以根据第一载波的路损、网络设备配置的功率控制参数，按照现有功率控制计算公式确定第一载波上发送上行信号的功率。
如此，当终端为室外终端时，因没有穿透损耗对上行路损的影响，因此，终端仅考虑到影响上行路损的因素：路径损耗，根据下行载波路损、以及上行载波和下行载波间该因素的差值计算出上行路损，提高了上行路损计算的准确性，进而提高了上行信号的功率的准确性。

图4所示的UE可以执行本申请实施例提供的路径确定方法中UE执行的操作。如：可以从网络设备接收第一偏移值，并在UE为室内UE时，根据第一偏移值确定上行载波上的上行信号的功率。
下面结合图2所示的5G系统，对本发明实施例提供的功率确定方法进行详细描述。此外，需要说明的是，虽然在下述方法流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图5为本发明实施例提供的一种功率确定方法流程图，由如图4所示的UE和图3所示的gNB交互执行，如图5所示，该方法可以包括以下步骤：
步骤501：gNB为UE配置第一偏移值。
其中，第一偏移值根据第一载波的穿透损耗与第二载波的穿透损耗确定，优选的，第一偏移值可以为：第一载波的穿透损耗与第二载波的穿透损耗的差值，第一载波为UE的上行载波，第二载波为UE的TDD载波或下行载波。
在本发明实施例中，穿透损耗(penetration loss)是指信号在传输时，当信号源在建筑物外，建筑物外的信号强度与建筑物内的信号强度的比值(单位DB)。穿透损耗与建筑物的结构，建筑物材质，信号源位置等有关。穿透损耗还是载波频率的函数，频率低损耗小，频率高损耗大。第一载波的穿透损耗是指UE和gNB在第一载波传输信号时的穿透损耗。第二载波的穿透损耗是指UE和gNB在第二载波传输信号时的穿透损耗。
可选的，可以根据下述公式计算出任一载波的穿透损耗PL tw：
Figure PCTCN2018091550-appb-000001
PL tw是多种材质的穿透损耗的一个加权值，每种材质用i表示，其中，PL npi是一个常数，p i是不同材质的比例，且
Figure PCTCN2018091550-appb-000002
L material_i＝a material_i+b material_i·f为材质i的穿透损耗，其中a material_i为材质i的穿透损耗的常数值，b material_i为材质i的穿透损耗与载频相关的参数，f为载波的载频。如下表1所示，不同的材质其穿透损耗是不同的：
表1
Figure PCTCN2018091550-appb-000003
例如，现有建模中典型的低损耗(Low-loss)穿透损耗模型的穿透损耗计算公式为：
Figure PCTCN2018091550-appb-000004
高损耗(High-loss)穿透损耗模型的穿透损耗计算公式为：
Figure PCTCN2018091550-appb-000005
步骤502：UE从gNB接收第一偏移值。
步骤503：UE根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率。
如此，在发送上行信号时，根据UE的传输环境，考虑到穿透损耗对上行路损的影响，根据与穿透损耗相关的偏移值确定出发送上行信号的功率，提高了上行信号发送功率的准确性。
可选的，在图5所示的技术方案中，UE可以从gNB获取第一门限值或者第二门限值或者第三门限值，当UE在第二载波上接收下行信号的接收功率小于或等于第一门限值时，或者当UE在第二载波上接收下行信号的路损小于或等于第二门限值时，或者当UE在第二载波上接收下行信号的RSRP小于或等于第三门限值时，UE才根据第一门限值确定UE是根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率；否则UE根据在第二载波上接收下行信号的接收功率确定在第一载波上发送上行信号的功率。
其中，第一门限值、第二门限值、第三门限值如发明内容所述，在此不再重复赘述。
下面仅以UE从gNB获取第一门限值，根据第一门限值确定是否根据第一偏移值确定发送上行信号的功率为例，对图5所示的技术方法进一步说明和介绍：
图6为本发明实施例提供的又一种功率确定方法流程图，由UE和gNB交互执行，如图6所示，该方法可以包括以下步骤：
步骤601：gNB为UE配置第一偏移值和第一门限值。
可选的，gNB可以通过系统消息或RRC信令为UE配置第一偏移值、以及通过系统消息或RRC信令为UE配置第一门限值。第一偏移值和第一门限值可以在同一条消息或信令，也可以在不同的消息或信令。
步骤602：UE从gNB接收第一偏移值和第一门限值。
步骤603：UE比较第二载波上接收下行信号的接收功率小于和第一门限值，当UE在第二载波上接收下行信号的接收功率小于或等于第一门限值时，执行步骤604；当UE在第二载波上接收下行信号的接收功率大于第一门限值时，执行步骤605。
步骤604：UE根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率。
可选的，UE根据在第二载波上接收下行信号的接收功率和第一偏移值确定在第一载波上发送上行信号的功率具体可以包括：
根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率；第二载波的路损为UE根据在第二载波上接收下行信号的接收功率确定的。
在本发明实施例中，路损是接收端接收信号的功率与发射端发射信号的功率的比值，包括路径损耗，阴影衰落，穿透损耗，天线增益等。路损可以是根据接收信号测量得到的，也可以是根据相关参数计算得到的。
其中，UE根据第二载波的路损、第一偏移值确定在第一载波上发送上行信号的功率具体可以包括下述方式1或方式2：
方式1：UE根据第二载波的路损、第一偏移值确定第一载波的路损，并根据第一载波的路损确定在第一载波上发送上行信号的功率；
可选的，UE根据第二载波的路损、第一偏移值确定第一载波的路损可以包括：
将第二载波的路损、第一偏移值以及第二偏移值相加后的结果作为第一载波的路损；例如：根据公式PL1＝PL2+offset1+offset2计算第一载波的路损PL1；
或者，在第二偏移值用于配置第一载波的上行功率控制参数的情况下，将第二载波的路损和第一偏移值相加后的结果作为第一载波的路损；例如，根据公式PL1＝PL2+offset2计算第一载波的路损PL1，
其中，PL2为第二载波的路损，offset1为第二偏移值，offset2为第一偏移值，第二偏移值为第一载波的路径损耗和第二载波的路径损耗的差值。
在本发明实施例中，路径损耗(path loss)，或称传播损耗，指电波在空间传播所产生的损耗，是由发射功率的辐射扩散及信道的传播特性造成的，反映宏观范围内接收信号功率均值随收发信机的距离的变化。穿透损耗与信号的传输介质，信号传输环境，接收端和发射端的距离有关。路径损耗还是载波频率的函数，频率低损耗小，频率高损耗大。第一载波的路径损耗是指UE和gNB在第一载波传输信号时的路径损耗。第二载波的路径损耗是指UE和gNB在第二载波传输信号时的路径损耗。
可选的，可以根据下述公式计算出任一载波的路径损耗PL：
PL＝32.4+21log 10(d)+20log 10(f)其中，d为接收端和发射端的距离，f为载波的载频。
在计算出第一载波的路损后，UE可以参照现有功率控制公式，结合确定出的上行路损计算出上行信号的发送功率，其中，现有功率控制公式如具体实施方式部分。
可选的，UE可以根据第一载波的路损、网络设备配置的功率控制参数，按照功率控制计算公式确定第一载波上发送上行信号的功率，功率的取值单位为dBm。
需要说明的是，本发明实施例中的功率控制计算公式可以参照现有功率控制计算公式，如：物理上行共享信道(physical uplink shared channel，PUSCH)的功率控制公式可以为：
Figure PCTCN2018091550-appb-000006
探测参考信号(sounding reference signal，SRS)的功率控制公式可以为：
P SRS,c(i)＝min{P CMAX,c(i),10log 10(M SRS,c)+P O_SRS,c(m)+α SRS,c·PL c+f SRS,c(i)}或者
P SRS,c(i)＝min{P CMAX,c(i),P SRS_OFFSET,c(m)+10log 10(M SRS,c)+P O_PUSCH,c(j)+α c(j)·PL c+f c(i)}
物理上行链路控制信道(physical uplink control channel，PUCCH)的功率控制公 式可以为：
Figure PCTCN2018091550-appb-000007
其中，上述公式中的i为子帧编号，c为载波编号，P CMAX,c(i),为gNB的最大发射功率，M PUSCH,c(i))为第i个子帧第c个载波上PUSCH的数目，P O_PUSCH,c(j)为目标接收功率，α c(j)为路损补偿因子，PL c为路损，△ TF,c(i)为与调制方式相关的调整量，f c(i)为功率控制因子。
方式2：UE可以根据下述公式一或者公式二确定在第一载波上发送上行信号的功率P：
公式一：P＝min{P max,FUNCTION(M,P 0,△,f)+α·PL+offset}，
公式二：P＝min{P max,FUNCTION(M,P 0,△,f)+α·PL+α·offset}，
其中，在公式一和公式二中，offset为第一偏移值；
PL根据第二载波的路损确定，PL为第二载波的路损，或者，PL为第二载波的路损和第二偏移值相加后的结果，第二载波的路损为UE根据在第二载波上接收下行信号的接收功率确定的，第二偏移值为根据第一载波的路径损耗和第二载波的路径损耗确定的；
P max为UE在第一载波的最大发射功率；
FUNCTION(M,P 0,△,f)为上行功率控制中与M,P 0,△,f有关的函数，M为UE在第一载波上发送上行信号占用的资源块数目，P 0为UE从网络设备获取的目标接收功率相关的功率控制参数，△为UE从网络设备获取的编码调制方式相关的功率控制参数，f为UE从网络设备获取的功率命令相关的功率控制参数；
α为UE从网络设备获取的路损补偿相关的功率控制参数。
如此，可以UE可以直接根据第一偏移值计算出发送上行信号的功率，不需要先计算出上行路损，再根据上行路损计算出发送上行信号的功率，降低了UE的计算复杂度。
可选的，在本发明实施例中，针对不同的上行信号，函数FUNCTION(M,P 0,△,f)的表现形式是不同的，例如：对于物理上行共享信道(physical uplink shared channel，PUSCH)，FUNCTION(M,P 0,△,f)为：
10log 10(M PUSCH,c(i))+P O_PUSCH,c(j)+△ TF,c(i)+f c(i)
探测参考信号(sounding reference signal，SRS)：
10log 10(M SRS,c)+P O_SRS,c(m)+f SRS,c(i)或者
10log 10(M SRS,c)+P O_PUSCH,c(j)+f c(i)
物理上行链路控制信道(physical uplink control channel，PUCCH)：
P 0_PUCCH+h(n CQI,n HARQ,n SR)+△ F_PUCCH(F)+△ TxD(F')+g(i)
其中，上述公式中的i为子帧编号，c为载波编号，P CMAX,c(i),为gNB的最大发射功率，M PUSCH,c(i))为第i个子帧第c个载波上PUSCH的数目，P O_PUSCH,c(j)为目标接收功率，△ TF,c(i)为与调制方式相关的调整量，f c(i)为功率控制因子。
步骤605：UE根据第二载波上接收下行信号的接收功率确定在第一载波上发送上行信号的功率。
可选的，UE根据第二载波上接收下行信号的接收功率确定在第一载波上发送上行信号的功率可以包括：
根据第二载波的路损确定在第一载波上发送上行信号的功率；第二载波的路损为UE根据在第二载波上接收下行信号的接收功率确定的。
可选的，UE根据第二载波的路损确定在第一载波上发送上行信号的功率可以包括：UE根据第二载波的路损确定第一载波的路损，根据第一载波的路损确定在第一载波上发送上行信号的功率。
其中，UE根据第二载波的路损确定第一载波的路损可以包括：
UE将第二载波的路损和第二偏移值相加后的结果作为第一载波的路损；第二偏移值为第一载波的路径损耗和第二载波的路径损耗的差值；例如：根据公式PL1＝PL2+offset1计算第一载波的路损PL1；
或者，在第二偏移值用于配置第一载波的上行功率控制参数的情况下，将第二载波的路损作为第一载波的路损；例如：根据公式PL1＝PL2计算第一载波的路损PL1。
可以理解的是，UE从gNB获取第二门限值或者第二门限值，根据第二门限值或者第三门限值确定是否根据第一偏移值确定发送上行信号的功率的方式可以参照图5所示方案，在此不再重复赘述。例如：终端可以比较第二载波上接收下行信号的路损和第二门限值，当终端在第二载波上接收下行信号的路损小于或等于第二门限值时，执行步骤604，当终端在第二载波上接收下行信号的路损大于第二门限值时，执行步骤605；或者，比较在第二载波上接收下行信号的RSRP和第三门限值；当终端在第二载波上接收下行信号的RSRP小于或等于第三门限值时，执行步骤604，当终端在第二载波上接收下行信号的RSRP大于第三门限值时，执行步骤605。
如此，当UE发送上行信号时，根据UE所处传输环境，考虑到穿透损耗对上行路损的影响，根据与穿透损耗相关的偏移值确定出上行信号发送功率，提高了上行信号发送功率的准确性。
上述主要从UE和gNB交互的角度对本发明实施例提供的方案进行了介绍。可以理解的是，各个网元，例如UE和gNB为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
本发明实施例可以根据上述方法示例对UE进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本发明实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
