具体实施方式
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，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，下面所描述的实施例仅仅是本发明的一部分实施例，而非全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(英文：Global System of Mobile communication，缩写：GSM)系统、码分多址(英文：Code Division Multiple Access，缩写：CDMA)系统、宽带码分多址(英文：Wideband Code Division Multiple Access，缩写：WCDMA)系统、通用分组无线业务(英文：General Packet Radio Service，缩写：GPRS)、长期 演进系统、LTE频分双工(英文：Frequency Division Duplex，缩写：FDD)系统、LTE时分双工(英文：Time Division Duplex，缩写：TDD)、通用移动通信系统(英文：Universal Mobile Telecommunication System，缩写：UMTS)或全球互联微波接入(英文：Worldwide Interoperability for Microwave Access，缩写：WiMAX)通信系统等。
本发明实施例提供的用户设备(英文：User Equipment，缩写：UE)包括终端(英文：Terminal)、移动台(英文：Mobile Station，缩写：MS)或移动终端(英文：Mobile Terminal)等，该UE可以经无线接入网(英文：Radio Access Network，缩写：RAN)与一个或多个核心网进行通信，例如，UE可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等，例如，UE还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。
本发明实施例提供的无线接入设备是指将UE接入到无线网络的设备，其例如可以是GSM或CDMA中的基站(英文：Base Transceiver Station，缩写：BTS)，也可以是WCDMA中的基站(英文：NodeB，缩写：NB)，还可以是LTE中的演进型基站(英文：Evolutional Node B，缩写：eNB)。
PUCCH用来承载上行控制信息，例如，混合自动重传请求(英文：Hybrid Automatic Repeat reQuest，缩写：HARQ)反馈信息，用于请求上行资源调度的调度请求指示(英文：Scheduling Request Indicator，缩写：SRI)等。VOIP业务对丢包率和时延比较敏感，针对PUCCH在上行干扰较大的情况下解调性能较差的问题，需要对VOIP场景下的上行控制信息的传输进行优化，以提高语音通信质量。
例如，在现有的HARQ反馈机制中，反馈状态分为ACK，NACK，DTX三态，ACK表示物理下行共享信道(英文：Physical Downlink Share Channel，缩写：PDSCH)解调正确，NACK表示PDSCH解调错误，DTX表示下行控制信息(英文：Downlink Control Information，缩写：DCI)丢失。下行数据的HARQ反馈主要在PUCCH上进行，但是在反馈时刻，如果有上行数据需要在物理上行共享信道(英文：Physical Uplink Share Channel，缩写：PUSCH)上发送时，则可以在PUSCH上传输HARQ反馈。然而，在VOIP场景下，上下 行业务往往是错开的，因此，HARQ反馈还是通过PUCCH进行传输的。PUCCH解调性能较差，在比较复杂的无线环境下，ACK可能被误解成NACK或者DTX的概率较高，ACK如果被错解，则丢包率和传输时延都会上升，影响用户通话感受。基于此，本发明实施例主动触发HARQ反馈时刻的PUSCH调度，以在PUSCH上反馈ACK或NACK，由于PUSCH解调性能明显优于PUCCH，在比较复杂的无线环境下，能够减少PUCCH解调性能较差的影响，减少HARQ反馈被误解的概率，提高用户通话感受。
再如，在比较复杂的无线环境下，PUCCH信道干扰不平衡，PUCCH格式1(format1)的信干噪比(英文：Signal to Interference plus Noise Ratio，缩写：SINR)偏置低，可能会导致SR(英文：Scheduling Request，缩写：SR)解调失败，SR高概率漏检，如此，无线接入网侧的设备(例如，eNB)无法及时为UE分配上行授权(英文：uplink grant，缩写：UP Grant)，从而导致VOIP业务丢包严重，甚至出现业务单通现象，影响用户通话感受。基于此，本发明实施例主动触发PUSCH调度，在SR漏检的情况下仍能为UE分配上行资源，减少SR漏检的影响，提高用户通话感受。
可见，本发明实施例通过主动触发PUSCH的调度，来减少PUCCH解调性能较差的影响，提高用户通话感受。以下结合附图进行描述：
请参阅图1，图1是本发明实施例提供的一种VOIP通信方法的第一实施例的流程示意图。本实施例中所描述的VOIP通信方法，包括以下步骤：
S101、无线接入设备确定正在进行VOIP业务的UE。
S102、无线接入设备监测对正在进行VOIP业务的UE的调度；
S103、无线接入设备根据所监测的调度，主动对该调度所针对的UE进行PUSCH的调度，以为该UE分配PUSCH资源；
S104、无线接入设备向该UE发送所分配的PUSCH资源的授权。
在本实施例中，无线接入设备找到正在进行VOIP业务的UE，而后根据对该UE的调度情况来确定是否主动对该UE进行PUSCH的调度，以为该UE分配PUSCH资源，如此，HARQ反馈可以在PUSCH上传输，且在SR漏检的情况下，UE仍能进行上行传输，以减少PUCCH解调失败或错误时带来的时延，提高用户通话感受。
VOIP业务可包括但不仅限于：视频业务、语音业务或者短信业务。确定UE是否正在进行VOIP业务可以通过判断UE是否正在进行这几种业务中的一种或多种来判断。
例如，在LTE系统中，对于VOIP业务的判断，可以通过QoS分类识别码(英文：QoS Class Identifier，缩写：QCI)来实现，其中QoS为服务质量(英文：quality of service，缩写：QoS)。数据无线承载(英文：Data Radio Bearer，缩写：DRB)上的QCI中，QCI1、QCI2和QCI5都是语音相关的QCI。其中，QCI1承载语音业务，QCI2承载视频业务，QCI5承载语音业务的会话初始化协议(英文：Session Initiation Protocol，缩写：SIP)信令，例如，建立和释放语音业务所用的SIP信令。在建立语音业务时，通过在QCI5发送SIP信令给核心网，触发核心网建立QCI1承载来完成，或者，对于可视电话需要建立QCI1和QCI2承载来完成。在结束语音业务时，在QCI5上传输相应的SIP信令，以触发核心网释放QCI1来完成，或者，对于可视电话业务，需要释放QCI1和QCI2来完成，认为通话结束。因此，判断UE是否在进行VOIP业务，可以通过QCI5的SIP信令来判断开始和结束；也可以通过QCI1的承载来判断。
在以上步骤S102中，无线接入设备监测对正在进行VOIP业务的UE的调度，可以包括对UE的下行调度的监测，也可以包括对UE的上行调度的监测。相应的，在步骤S103中可以根据对UE的下行调度或上行调度情况，确定是否主动对该UE进行PUSCH的调度。
其中，当无线接入设备监测到对UE进行了下行调度时，主动对UE进行PUSCH的调度，以为UE分配PUSCH资源，该PUSCH资源用于该下行调度的反馈，即用于UE在该PUSCH资源上发送下行调度所针对的下行VOIP数据包的反馈。
当无线接入设备监测到预设时间长度内未对UE进行上行调度时，主动对UE进行PUSCH的调度，以为UE分配PUSCH资源，该PUSCH资源用于UE发送上行VOIP数据。
以下分别结合图2和图6对这两种情况进行描述：
请参阅图2，图2是本发明实施例提供的一种VOIP通信方法的第二实施 例的流程示意图。本实施例中所描述的VOIP通信方法，包括以下步骤：
S201、无线接入设备确定正在进行VOIP业务的UE。
S202、无线接入设备监测对该UE的下行调度。
S203、当无线接入设备监测到对该UE进行了下行调度时，主动对该UE进行PUSCH的调度，以为该UE分配PUSCH资源，该PUSCH资源用于该下行调度的反馈。
S204、无线接入设备向该UE发送所分配的PUSCH资源的授权。
以上确定正在进行VOIP业务的UE的方法同以上实施例一，在此不再赘述。
HARQ使用停等协议(英文：stop-and-wait protocol)来发送数据。在停等协议中，发送端发送数据后，需要停下来等待接收端的反馈，收到反馈后才能决定下一次是发新包还是发重传包。如果每次发送信息后都停下来等待反馈，会导致资源浪费、吞吐量很低，因此引入了HARQ进程的概念。当一个HARQ进程在等待反馈时，发送端可以使用另一个HARQ进程来继续发送数据。每传输时间间隔(英文：Transmission Time Interval，缩写：TTI)只会对应一个HARQ进程号，且考虑处理延迟的合理上限，对于每个HARQ进程，每个调度时刻和针对该调度的反馈时刻之间相差固定的TTI。因此，无线接入设备对UE进行下行调度时，便可以确定该下行调度的反馈时刻。例如，无线接入设备对下行调度的授权时刻为T1，那么该下行调度的反馈时刻为T1+K1，其中，K1为所下行调度的授权到该下行调度的反馈的反馈时延，也可以理解为下行传输的HARQ反馈与下行传输之间的时间间隔。这里所说的各个时刻，例如授权时刻，反馈时刻等可以通过子帧号来反映，此外，K1的单位为TTI。
在频分双工(英文：Freuency Division Duplexing，缩写：FDD)通信系统中，K1的取值为4。在时分双工(英文：Time Division Duplexing，缩写：TDD)通信系统中，K1的取值根据上下行子帧配比和各上下行子帧配比的HARQ反馈时序确定。具体，可以参见3GPP标准36.213中的表格，Table 10.1.3.1-1，即如下表1的TDD的HARQ反馈时序所示：
表1
Figure PCTCN2015080068-appb-000001
表1中的第一列为TDD系统中的不同上下行配比的序号，如表2所示，TDD系统中有多种上下行配比的帧结构。每个帧包括10个子帧分别以编号0～9表示，且每种帧结构中用于下行传输的子帧以D表示，用于上行传输的子帧以U表示，S表示特殊子帧，用于上下行子帧间的切换，其包括DwPTS，UpPTS和GP部分，其中DwPTS用于下行传输，UpPTS用于上行传输，GP为保护期。
从表2可以看出，TDD系统中，下行子帧多、上行子帧少，无法做到每个下行子帧对应一个上行子帧来进行HARQ反馈。因此，所有第n-k个下行子帧的HARQ反馈都在第n个上行子帧上进行，其中n为子帧号，k的取值可以从表1中获得。请结合参考图3至图5所示配比0至配比2的HARQ反馈时序图。对于配比0，子帧2用于对之前6个子帧的下行传输进行上行反馈，此时k的取值为6，相应的K1的取值为6；子帧4用于对之前4个子帧的下行传输进行上行反馈，此时k的取值为4，相应的K1的取值为4。其它配比与之类似，在此不再详述。
表2
Figure PCTCN2015080068-appb-000002
以上原理也可以通过以下公式(1)来表述：
DL_Voip_SchStatus(CurrentTti-K1)＝TRUE   (1)
其中：公式(1)中CurrentTti表示当前时刻，DL_Voip_SchStatus(x)表示x时刻是否对UE进行了下行调度，K1的含义与取值与上面相同，在此不再赘述。如果对UE进行了下行调度，则DL_Voip_SchStatus的取值为TRUE，那么当前时刻便需要主动对UE进行PUSCH的调度；如果未对UE进行下行调度，则DL_Voip_SchStatus的取值为FALSE，那么当前时刻便不需要主动对UE进行PUSCH的调度。
对UE进行PUSCH的调度之后，还需要将为UE分配的PUSCH资源通知给UE，即向UE发送PUSCH资源的授权。该授权的发送在UE进行HARQ反馈之前以告知UE在哪些PUSCH资源上进行反馈。若记下行调度的授权时刻为T，则UE的反馈时刻为T+K1，那么该PUSCH资源的授权的发送时刻，即该PUSCH资源的授权时刻(也可以称为上行调度的授权时刻)为T+K1-K2，其中，K2为PUSCH资源的授权到PUSCH传输的传输时延。
目前，基站通过物理下行控制信道(英文：Physical Downlink Control Channel，缩写：PDCCH)向UE发送上行授权，UE通过检测PDCCH来获得上行授权，进而根据该上行授权进行PUSCH传输。在FDD系统中，PDCCH 上的授权到PUSCH传输之间的时延为4TTI。在TDD系统中，由于每种帧结构中，每个子帧固定用于上行传输或下行传输，因此UE在用于下行传输的子帧(例如下行子帧或特殊子帧)检测到上行授权之后，需要等待到用于上行传的子帧(例如上行子帧或特殊子帧)才能进行PUSCH传输，因此，在TDD系统中，PDCCH上的授权到PUSCH传输之间的时延跟上下行子帧配比相关，且表3中给出了每种上下行子帧配比的PUSCH传输时序。因此，在FDD通信系统中，K2的取值为4，在TDD通信系统中，K2的取值根据上下行子帧配比和各上下行子帧配比的PUSCH传输时序确定。具体，可以参见3GPP标准36.213中的表格，Table 8-2，即如下表3的TDD的PUSCH传输时序所示：
表3
Figure PCTCN2015080068-appb-000003
从表3中可以看出，对于配比2，子帧3用于对之后4个子帧的PUSCH传输进行授权，此时K2的取值为4；子帧8用于对之后4个子帧的PUSCH传输进行授权，此时K2的取值为4。其它配比与之类似，在此不再详述。
此时，以上公式(1)可以进一步优化为以下公式(2)
DL_Voip_SchStatus(CurrentTti-K1+K2)＝TRUE   (2)
其中：公式(2)中CurrentTti表示当前时刻，DL_Voip_SchStatus(x)表示x时刻是否对UE进行了下行调度，K1和K2的含义与取值与上面相同，在此不再赘述。如果对UE进行了下行调度，则DL_Voip_SchStatus的取值为TRUE，那么当前时刻便需要主动对UE进行PUSCH的调度；如果未对UE进 行下行调度，则DL_Voip_SchStatus的取值为FALSE，那么当前时刻便不需要主动对UE进行PUSCH的调度。
本实施例中，无线接入设备对正在进行VOIP业务的UE进行监测，当监测到对该UE进行了下行调度时，便主动对该UE发起PUSCH调度，以为该UE分配上行资源，使得UE利用分配的上行资源进行该下行调度的反馈。如此，反馈信息便可以在PUSCH上传输，PUSCH相对于PUCCH，其发射功率较高，解调性能更好，极大地降低了解调失败或错误的概率，从而改善了语音通话的质量。
请参阅图6，图6是本发明实施例提供的一种VOIP业务的通信方法的第三实施例的流程示意图。本实施例中所描述的方法，包括以下步骤：
S601、无线接入设备确定正在进行VOIP业务的UE。
S602、无线接入设备监测对该UE的上行调度。
S603、当预设时间长度内无线接入设备未对该UE进行上行调度时，主动对该UE进行PUSCH的调度，以为该UE分配PUSCH资源，该PUSCH资源用于所述UE发送上行VOIP数据。
S604、无线接入设备向该UE发送所分配的PUSCH资源的授权。
以上确定正在进行VOIP业务的UE的方法同以上实施例一，在此不再赘述。
当UE进行VOIP业务时，可以处于以下两种状态之一：
(1)、通话状态：主要指UE的使用者正在说话时UE的状态，在通话状态下，通常每20ms产生一个数据包，以下将通话状态下UE产生数据包的周期称为第一周期。
(2)、静默状态：主要指UE的使用者正在接听时UE的状态，在静默状态下，通常每160ms产生一个数据包，以下将静默状态下UE产生数据包的周期称为第二周期。
无论UE处于何种状态，在VOIP场景下，无线接入设备在一定时长内应该可以接收到该UE的上行数据包。如果无法接收该UE的上行数据包，可能是因为UE的PUCCH解调错误或失败，无线接入网设备无法获得该UE的SR， 进而无法对该UE进行上行调度。本实施例不以UE的SR为依据，主动对该UE进行PUSCH调度，为其分配上行资源，以便UE发送上行VOIP数据包。当然，也有极端情况下，通话的某一方一直未有上行数据包产生，但是，仍不影响本方案从整体上提高语音通话的质量。
以上原理也可以通过以下公式(3)来表述：
(CurrentTTI-LastPreAllocationTime)>＝PreAllocationMinPeriodicity   (3)
其中，CurrentTTI表示当前时刻，LastPreAllocationTime表示与当前时刻最接近的上一次上行调度时刻，PreAllocationMinPeriodicity表示预设时间长度。当以上公式(3)成立时，主动对该UE发起PUSCH调度。
关于预设时间长度，本领域技术人员可以根据需要进行设置。本发明实施例不做限制，以下给出一种示例性的设置方式，如公式(4)所示，其仅用于举例，并非用于限制本发明。
PreAllocationMinPeriodicity＝(UE处于通话状态？Period0：第二周期)，
Period0＝(SR周期>＝t？t：第一周期)   (4)
在公式(4)中，第一周期与第二周期的含义同以上描述，即分别为UE处于通话状态和静默状态下的数据包产生周期，通常第二周期大于第一周期。t为一时间长度预设值，其取值介于第一周期与第二周期之间。
从公式(4)可以看出，当UE处于通话状态时，预设时间长度PreAllocationMinPeriodicity的取值为Period0；当UE不处于通话状态时，即处于静默状态时，预设时间长度PreAllocationMinPeriodicity的取值为第二周期。Period0的取值与SR周期相关，当SR周期大于或等于预设值t时，Period0的取值为t；当SR周期小于预设值t时，Period0的取值为第一周期。
本实施例中，无线接入设备对正在进行VOIP业务的UE进行监测，当监测到预设时间长度内未对该UE进行上行调度时，不再依据解码出的SR，主动对该UE进行PUSCH的调度，以为该UE分配上行资源，使得UE可以利用该上行资源发送上行VOIP数据。如此，在SR漏检的情况下，UE仍能进行上行传输，以减少PUCCH解调失败或错误时带来的时延，提高用户通话感受。
请参阅图7，图7是本发明实施例提供的一种VOIP通信方法的第四实施例的流程示意图。本实施例中所描述的VOIP通信方法，包括以下步骤：
S701、UE接收无线接入设备为该UE分配的PUSCH资源的授权，其中该UE与该无线接入设备之间正在进行VOIP业务，且该PUSCH资源为该无线接入设备根据对该UE的调度的监控主动为该UE分配的。
S702、UE根据该授权确定该PUSCH资源。
S703、UE在所确定的PUSCH资源上进行上行传输。
可选地，该PUSCH资源为该无线接入设备在监测到对该UE进行了下行调度时主动为所述UE分配的用于该下行调度的反馈的资源。
进一步可选地，下行调度的授权时刻为T，该下行调度的反馈时刻为T+K1，其中，K1为该下行调度的授权到该下行调度的反馈的反馈时延。
需要指出的是，在FDD通信系统中，K1的取值为4，在TDD通信系统中，K1的取值根据上下行子帧配比和各上下行子帧配比的HARQ反馈时序确定。
进一步地，PUSCH资源的授权时刻为T+K1-K2，其中，K2为该PUSCH资源的授权到PUSCH传输的传输时延。
进一步需要指出的是，在FDD通信系统中，K2的取值为4，在TDD通信系统中，K2的取值根据上下行子帧配比和各上下行子帧配比的PUSCH传输时序确定。
相应地，该PUSCH资源为该无线接入设备在监测到预设时间长度内未对该UE进行上行调度时主动为该UE分配的用于该UE发送上行VOIP数据的资源。
可选地，当该UE处于通话状态时，该预设时间长度为第一时间长度；当该UE处于静默状态时，该预设时间长度为第二时间长度，且该第一时间长度小于第二时间长度。
由上可见，本实施例中，UE接收无线接入设备为该UE分配的PUSCH资源的授权，并根据该授权确定该PUSCH资源，在所确定的PUSCH资源上进行上行传输，其中该UE与该无线接入设备之间正在进行VOIP业务，且该PUSCH资源为该无线接入设备根据对该UE的调度的监控主动为该UE分配 的。如此，HARQ反馈可以在PUSCH上传输，且在SR漏检的情况下，UE仍能进行上行传输，以减少PUCCH解调失败或错误时带来的时延，提高用户通话感受。

本实施例中，无线接入设备找到正在进行VOIP业务的UE，而后根据对该UE的调度情况来确定是否主动对该UE进行PUSCH的调度，以为该UE分配PUSCH资源，如此，HARQ反馈可以在PUSCH上传输，且在SR漏检的情况下，UE仍能进行上行传输，以减少PUCCH解调失败或错误时带来的时延，提高用户通话感受。
