Description

一种语音业务的处理方法及基站 技术领域
本发明涉及语音通信技术领域，尤其涉及一种语音业务的处理方法及基站。
背景技术
长期演进网络(Long Term Evolution，LTE)被定义为新一代无线通信标准，其是一个单纯的分组交换系统，不支持传统的电路交换业务，因此LTE只能以互联网协议(Internet Protocol，IP)语音的方式来提供语音业务，这无疑带来很多新的挑战。用户期望LTE网络的语音质量可以等同于电路交换网络中的语音质量，然而在语音通信的场景中，常常会存在语音单通的问题，所谓语音单通是指通话一方听不到通话另一方声音的情况。然而语音单通是一个系统性问题，涉及核心网、传输网、无线网络和用户终端等网元，例如，无线信号覆盖较差、用户终端的软件或硬件问题导致无法同步于服务小区、核心网中基站通信机制出现问题等等。由于所涉及的网元较多，因此让解决语音单通的难度加大。目前，主要依赖于语音单通问题出现后的客户投诉，但是一旦发生投诉，其实语音单通现象已经发生了数小时甚至一天以上，而维护人员无法预知，只能被动的等待投诉，在接收到投诉之后，只能通过大量的人工拨测等方式以重现语音单通现象，但是重现的概率很低，降低语音单通问题的解决效率，也影响了用户的语音通信质量。
发明内容
本发明实施例提供了一种语音业务的处理方法及基站，能够及时解决语音单通问题，提高用户的语音通信质量。
第一方面，本发明实施例提供了一种语音业务的处理方法，包括：在检测周期内，若用户终端存在QCI为1的连接且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数小于第一阈值，所述基站获取在所述检测周期内的所述用户终端的信号与干扰加噪声比SINR、所述用户终端的MCS、所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站RLC层接 收到的所述用户终端的VoLTE数据包的总数，若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，所述基站向所述用户终端发送小区内切换命令。由于在检测周期内用户终端存在QCI为1的连接但基站的PDCP层收到的用户终端的VoLTE数据包较少的情况下，表示用户终端在检测周期内出现了语音单通的问题，进一步若根据检测周期内的用户终端的SINR、MCS、基站MAC层接收到的用户终端的VoLTE数据包的错包率、基站RLC层接收到的用户终端的VoLTE数据包的总数确定用户终端当前所处的小区的无线环境较好，向用户终端发送小区内切换命令，这样用户终端可以通过重新配置无线承载继续在该小区中通信，以使基站的PDCP层能够收到较多的用户终端的VoLTE数据包，因此这样能够及时解决语音单通问题，提高用户的语音通信质量。
结合第一方面，在第一方面的第一种实现方式中，所述基站还可以若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，所述基站向所述用户终端发送无线资源控制RRC连接释放命令。由于SINR小于第一预设值，或MCS小于第二预设值，或基站MAC层接收到的用户终端的VoLTE数据包的错包率大于第三预设值，或基站RLC层接收到的用户终端的VoLTE数据包的总数小于第四预设值，表示可能用户终端当前所处的无线环境较不好，因此，基站可以向用户终端发送RRC连接释放命令，并通过用户终端当前使用的频点重新建立RRC连接，或者通过RRC连接释放命令中的异频频点重新建立RRC连接，以恢复由于无线环境较差造成的语音单通。
第二方面，本发明实施例提供了另一种语音业务的处理方法，包括：在检测周期内，若用户终端存在QCI为1的连接，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数大于第一阈值，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值，所述基站获取在所述检测周期内的所述用户终端的SINR、所述用户终端的MCS、所述基站MAC层收 到的所述用户终端的VoLTE数据包的错包率和所述基站RLC层收到的所述用户终端的VoLTE数据包的总数；若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，所述基站向所述用户终端发送小区内切换命令。由于在检测周期内用户终端存在QCI为1的连接但基站的PDCP层收到的用户终端的VoLTE数据包较多但错包率较高的情况下，表示用户终端在检测周期内出现了语音单通的问题，进一步若根据检测周期内的用户终端的SINR、MCS、基站MAC层接收到的用户终端的VoLTE数据包的错包率、基站RLC层接收到的用户终端的VoLTE数据包的总数确定用户终端当前所处的小区的无线环境较好，向用户终端发送小区内切换命令，这样用户终端可以通过重新配置无线承载继续在该小区中通信，以使基站的PDCP层能够收到较多的用户终端的VoLTE数据包，因此这样能够及时解决用户终端的语音单通问题，提高用户的语音通信质量。
结合第二方面，在第二方面的第一种实现方式中，所述基站还可以在若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，所述基站向所述用户终端发送无线资源控制RRC连接释放命令。由于SINR小于第一预设值，或MCS小于第二预设值，或基站MAC层接收到的用户终端的VoLTE数据包的错包率大于第三预设值，或基站RLC层接收到的用户终端的VoLTE数据包的总数小于第四预设值，表示可能用户终端当前所处的无线环境较不好，因此，基站可以向用户终端发送RRC连接释放命令，并通过用户终端当前使用的频点重新建立RRC连接，或者通过RRC连接释放命令中的异频频点重新建立RRC连接，以恢复由于无线环境较差造成的语音单通。
结合第二方面或第二方面的第一种实现方式，在第二方面的第二种实现方式中，在使用鲁棒性头压缩ROHC时，所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率，包括：若所述基站的PDCP层收到的所述用户终端的VoLTE数据包包含的版本号不是IPv4或IPv6，所述基站将所述PDCP层收 到的所述用户终端的VoLTE数据包的错包数加1，并根据所述PDCP层收到的所述用户终端的VoLTE语音包的总数和错包数计算所述基站的所述PDCP层收到的所述用户终端的VoLTE数据包的错包率。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，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地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，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他实施例，都应当属于本发明保护的范围。
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。另外，本发明的说明书和权利要求书及附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于理解本发明，下面先介绍下本发明实施例适用的一种可能的网络架构图。请参见图1，是本发明实施例的一种可能的网络架构图。图1所示的 网络架构图为长期演进网络(Long Term Evolution，LTE)架构图，LTE接入网称为演进型通用陆地无线接入网(Evovled UTRAN，E-UTRAN)，E-UTRAN结构中包含了若干个eNode B，eNode B之间底层采用IP传输，在逻辑上通过X2接口互相连接，每个eNode B通过S1接口连接到演进分组核心(Evolved Packet Core，EPC)网络的移动管理实体(Mobility Management Entity，MME)、服务网关(Signaling Gateway，S-GW)，具体是通过S1-MME接口和MME相连，通过S1-U和S-GW连接，S1-MME和S1-U可以被分别看作S1接口的控制平面和用户平面。传输业务、应用数据的叫做用户平面，用户平面上承载的是用户的应用数据。例如，通过用户终端(User Equipment，UE)手机上网，看到网页中的内容、聊天的内容等，这些都是通过用户平面传输的。传输信令信息的叫做控制平面，控制平面上承载的是用户和网络的交互控制信息。例如，用户上网时建立、维护、释放与网络间的链路时，都是通过控制平面来完成的。eNode B和UE之间的用户平面协议栈包括分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)、无线链路控制(Radio Link Control，RLC)、媒体接入控制(Media Access Control，MAC)和物理层(Physical layer，PHY)；eNode B和UE之间的控制平面协议栈包括无线资源控制(Radio Resource Control，RRC)、PDCP、RLC、MAC和PHY。
进一步地，RRC层负责建立无线承载和配置eNode B和UE间由RRC信令控制的所有底层，其中底层包括PDCP、RLC、MAC和PHY。PDCP层负责执行头压缩以减少无线接口必须传送的比特流量。PDCP层还负责传输数据的加密和完整性保护功能；在接收端，PDCP协议将负责执行解密及解压缩功能。RLC层负责分段与连接、重传处理，以及对高层数据的顺序传送。RLC层以无线承载的方式为PDCP层提供服务。MAC层负责处理混合自动重传请求(Hybrid Automatic Repeat request，HARQ)与上下行调度。MAC层将以逻辑信道的方式为RLC层提供服务。PHY层负责处理编译码、调制解调、多天线映射以及其它电信物理层功能。物理层以传输信道的方式为MAC层提供服务。
实际应用中，LTE可以向接入LTE的用户终端提供语音业务、视频业务、数据业务等，例如LTE的语音业务(Voice over LTE，VoLTE)数据包。进一 步，在LTE的语音业务中，有可能会有语音单通的情况发生，在现有技术中，主要依赖于语音单通问题出现后的客户投诉，但是一旦发生投诉，其实语音单通现象已经发生了数小时甚至一天以上，而维护人员无法预知，只能被动的等待投诉，在接收到投诉之后，只能通过大量的人工拨测等方式以重现语音单通现象，但是重现的概率很低，降低语音单通问题的解决效率。在本发明实施例中，若在检测周期内通过服务等级分类识别码(QoS Class Identifier，QCI)和基站的PDCP层收到的用户终端的VoLTE数据包的总数的判断最终确定用户终端发生语音单通的情况下，基站可以在满足一定条件的情况下向用户终端发送小区内切换命令，这样能够让用户终端通过小区内切换命令及时解决语音单通问题，进而提高用户的语音通信质量。
在本发明实施例中，基站可以是图1所示的可能的网络架构中的eNode B。本发明实施例所涉及的用户终端可以包括但不限定于终端(Terminal)、移动终端(Mobile Terminal)等，该用户终端可以经无线接入网与一个或多个核心网进行通信，例如，UE可以是移动手机、平板电脑、个人数字助理(Personal Digital Assistant,PDA)、移动互联网设备(Mobile Internet Device，MID)、智能穿戴设备(如智能手表、智能手环)等各类的终端设备。
请参见图2，为本发明实施例提供了一种语音业务的处理方法的流程示意图。如图2所示，本发明实施例的所述方法可以包括以下步骤201-步骤203。
201，在检测周期内，若用户终端存在服务质量分类识别码QCI为1的连接且所述基站的分组数据会聚协议PDCP层收到的所述用户终端的长期演进网络语音业务VoLTE数据包的总数小于第一阈值，所述基站获取在所述检测周期内的所述用户终端的信号与干扰加噪声比SINR、所述用户终端的调制与编码方式MCS、所述基站介质访问控制MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站无线链路控制RLC层接收到的所述用户终端的VoLTE数据包的总数。
具体的，在检测周期内，若用户终端存在QCI为1的连接且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数小于第一阈值，所述基站获取在所述检测周期内的所述用户终端的信号与干扰加噪声比(Signal to  Interference plus Noise Ratio，SINR)、所述用户终端的调制与编码方式(Mymova Checkin System，MCS)、所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站无线链路控制RLC层接收到的所述用户终端的VoLTE数据包的总数。
可以理解的是，QCI为1的连接表示当前用户终端的语音业务的优先级最高，所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数小于第一阈值，在两个条件同时满足的情况下，表示用户终端在语音业务优先级最高的情况下所述基站的PDCP层收到的所述用户终端的VoLTE数据包仍较少，此时，所述基站认为所述用户终端在所述检测周期内出现语音单通。可选的，其中，所述第一阈值是由所述基站自定义设定的，比如0或10等，可选的，所述检测周期是由所述基站自定义设定的。本发明实施例对第一阈值和检测周期的具体数值不做限定。
进一步，所述基站获取的在所述检测周期内的所述用户终端的SINR、所述用户终端的MCS、所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数中，所述用户终端的SINR用于表示所述用户终端在检测周期内的语音业务过程中语音信号与干扰信号加噪声信号的功率比值，可以理解的是，所述用户终端的SINR越大表示当前无线环境的干扰和噪声越小。由于MCS可以对应多种调制方式，一个调制方式对应一个物理传输速率，因此所述用户终端的MCS可以用于表示所述用户终端在所述检测周期内的物理传输速率，可选的，MCS可以采用索引值的方式体现，可以理解的是，当由所述用户终端的MCS确定的物理传输速率越大表示当前的无线环境越好。所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率是指所述基站的MAC层根据VoLTE数据包校验机制确定的错包数与VoLTE数据包总数的比值，所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率越小表示当前的无线环境越好。所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数是指经由所述基站的MAC层校验之后传输至所述基站的RLC层的VoLTE数据包的总数量，可以理解的是，在所述基站的MAC层会对收到的所述用户终端的VoLTE数据包进行校验之后，将校验正确的VoLTE数据包传输至所述基站的RLC层，因 此所述基站的MAC层的VoLTE数据包的总数不小于所述基站的RLC层的VoLTE数据包总数。
需要说明的是，所述基站的各个协议栈收到的所述用户终端的VoLTE数据包均是各不相同的，是因为各个协议栈都需要执行相应的处理之后发送至下一个协议层。
202，若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，所述基站向所述用户终端发送小区内切换命令。
具体的，若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，从各个条件可以看出，当前小区的无线环境较好，但是在检测周期内所述用户终端存在QCI为1的连接且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数小于第一阈值，因此有可能此次所述用户终端产生的单通是由于PDCP实体发生故障造成的，又由于每一个RB连到一个PDCP实体，每一个PDCP实体对应于一个RLC实体，通过重新配置RB的方式可以实现重新配置PDCP实体和RLC实体，进而恢复由于PDCP实体故障造成的语音单通。可选的，所述小区内切换命令用于指示所述用户终端重新配置无线承载，因此所述基站可以通过向所述用户终端发送小区内切换命令以使所述用户终端根据所述小区内切换命令重新配置无线承载。
203，在若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，所述基站向所述用户终端发送无线资源控制RRC连接释放命令。
具体的，在若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，各个条件之间采用或者的关系是用于表示上述四个条件中只要 有一个条件满足即可以向所述用户终端发送RRC连接释放命令。可以理解的是，所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，说明可能所述用户终端当前所处的无线环境较不好，因此，所述基站可以向所述用户终端发送RRC连接释放命令，相应地，所述用户终端接收到所述RRC连接释放命令之后，释放当前的RRC连接，并通过用户终端当前使用的频点重新建立RRC连接。可选的，所述RRC连接释放命令中可以携带异频频点，所述异频频点是指与所述用户终端在接收到所述RRC连接释放命令之前所使用的频点不同，这样，所述用户终端在接收到所述RRC连接释放命令之后。所述用户终端可以通过异频频点搜索对应的小区，以恢复由于无线环境较差造成的语音单通。
需要说明的是，可选的，所述基站可以在所述用户终端存在QCI为1且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数等于第一阈值的情况下执行步骤201的获取动作。可选的，所述SINR等于第一预设值，所述MCS等于第二预设值，所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率等于第三预设值，所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数等于第四预设值，这四个情况中的任一种情况都可以增加至步骤202或者步骤203，本发明实施例对此不做限定。
需要说明的是，在本发明实施例中步骤201和步骤202是作为必要步骤，而步骤203可以作为可选步骤；可以理解的是，由于步骤202和步骤203介绍的是两种不可能同时存在的情况，因此，在一种可行的实施例中，步骤201和步骤203可以作为必要步骤，而步骤202作为可选步骤，这一可行的实施例中每个步骤的具体执行过程可参见图2所示实施例，在此不再赘述。
在本发明实施例中，在检测周期内用户终端存在QCI为1的连接但基站的PDCP层收到的用户终端的VoLTE数据包较少的情况下，表示用户终端在检测周期内出现了语音单通的问题，进一步若根据检测周期内的用户终端的SINR、MCS、基站MAC层接收到的用户终端的VoLTE数据包的错包率、基站RLC层接收到的用户终端的VoLTE数据包的总数确定用户终端当前所处的 小区的无线环境较好，向用户终端发送小区内切换命令，这样用户终端可以通过重新配置无线承载继续在该小区中通信，以使基站的PDCP层能够收到较多的用户终端的VoLTE数据包，因此这样能够及时解决用户终端的语音单通问题，提高用户的语音通信质量。
请参见图3，为本发明实施例提供了另一种语音业务的处理方法的流程示意图。如图3所示，本发明实施例的所述方法可以包括以下步骤301-步骤303。
301，在检测周期内，若用户终端存在服务质量分类识别码QCI为1的连接，且所述基站的分组数据会聚协议PDCP层收到的所述用户终端的长期演进网络语音业务VoLTE数据包的总数大于第一阈值，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值，所述基站获取在所述检测周期内的所述用户终端的信号与干扰加噪声比SINR、所述用户终端的调制与编码方式MCS、所述基站介质访问控制MAC层收到的所述用户终端的VoLTE数据包的错包率和所述基站无线链路控制RLC层收到的所述用户终端的VoLTE数据包的总数。
具体的，在检测周期内，若用户终端存在QCI为1的连接，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数大于第一阈值，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值，所述基站获取在所述检测周期内的所述用户终端的SINR、所述用户终端的MCS、所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数。可以理解的是，QCI为1的连接表示当前用户终端的语音业务的优先级最高，所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数大于第一阈值，所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值，在三个条件同时满足的情况下，表示用户终端在语音业务优先级最高的情况下所述基站的PDCP层收到的所述用户终端的VoLTE数据包较多但错包率较高，此时，所述基站认为所述用户终端在所述检测周期内出现语音单通。可选的，其中，所述第一阈值和所述第二阈值是由所述基站自定义设定的，可选的，所述检测周期是由所述基站自定义设定的。本发明实施例对第一阈值、第二阈值 和检测周期的具体数值不做限定。
进一步，在一种可行的方案中，在使用鲁棒性报头压缩(Robust Header Compression，ROHC)时，若所述基站的PDCP层收到的所述用户终端的VoLTE数据包包含的版本号不是IPv4或IPv6，所述基站将所述PDCP层收到的所述用户终端的VoLTE数据包的错包数加1，并根据所述PDCP层收到的所述用户终端的VoLTE语音包的总数和错包数计算所述基站的所述PDCP层收到的所述用户终端的VoLTE数据包的错包率。在另一种可行的方案中，在未使用ROHC时，若所述基站的PDCP层收到的所述用户终端的VoLTE数据包存在CRC错误，所述基站将所述PDCP层收到的所述用户终端的VoLTE数据包的错包数加1，并根据所述PDCP层收到的所述用户终端的VoLTE语音包的总数和错包数计算所述基站的所述PDCP层收到的所述用户终端的VoLTE数据包的错包率。
进一步，所述基站获取的在所述检测周期内的所述用户终端的SINR、所述用户终端的MCS、所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率和所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数中，所述用户终端的SINR用于表示所述用户终端在检测周期内的语音业务过程中语音信号与干扰信号加噪声信号的功率比值，可以理解的是，所述用户终端的SINR越大表示当前无线环境的干扰和噪声越小。由于MCS可以对应多种调制方式，一个调制方式对应一个物理传输速率，因此所述用户终端的MCS可以用于表示所述用户终端在所述检测周期内的物理传输速率，可选的，MCS可以采用索引值的方式体现，可以理解的是，当由所述用户终端的MCS确定的物理传输速率越大表示当前的无线环境越好。所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率是指所述基站的MAC层根据VoLTE数据包校验机制确定的错包数与VoLTE数据包总数的比值，所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率越小表示当前的无线环境越好。所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数是指经由所述基站的MAC层校验之后传输至所述基站的RLC层的VoLTE数据包的总数量，可以理解的是，在所述基站的MAC层会对收到的所述用户终端的VoLTE数据包进行校验之后，将校验正确的VoLTE数据包传输至所述基站的RLC层，因 此所述基站的MAC层的VoLTE数据包的总数不小于所述基站的RLC层的VoLTE数据包总数。
需要说明的是，所述基站的各个协议栈收到的所述用户终端的VoLTE数据包均是各不相同的，是因为各个协议栈都需要执行相应的处理之后发送至下一个协议层。
302，若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，所述基站向所述用户终端发送小区内切换命令。
具体的，若所述SINR大于第一预设值，且所述MCS大于第二预设值，且所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率小于第三预设值，且所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数大于第四预设值，从各个条件可以看出，当前小区的无线环境较好，但是在检测周期内所述用户终端存在QCI为1的连接，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数大于第一阈值，且所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值，因此有可能此次所述用户终端产生的单通是由于PDCP实体发生故障造成的，又由于每一个RB连到一个PDCP实体，每一个PDCP实体对应于一个RLC实体，通过重新配置RB的方式可以实现重新配置PDCP实体和RLC实体，进而恢复由于PDCP实体故障造成的语音单通。可选的，所述小区内切换命令用于指示所述用户终端重新配置无线承载，因此所述基站可以通过向所述用户终端发送小区内切换命令以使所述用户终端根据所述小区内切换命令重新配置无线承载。
303，在若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，所述基站向所述用户终端发送无线资源控制RRC连接释放命令。
具体的，在若所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小 于第四预设值，各个条件之间采用或者的关系是用于表示上述四个条件中只要有一个条件满足即可以向所述用户终端发送RRC连接释放命令。可以理解的是，所述SINR小于第一预设值，或所述MCS小于第二预设值，或所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率大于第三预设值，或所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数小于第四预设值，说明可能所述用户终端当前所处的无线环境较不好，因此，所述基站可以向所述用户终端发送RRC连接释放命令，相应地，所述用户终端接收到所述RRC连接释放命令之后，释放当前的RRC连接，并通过用户终端当前使用的频点重新建立RRC连接。可选的，所述RRC连接释放命令中可以携带异频频点，所述异频频点是指与所述用户终端在接收到所述RRC连接释放命令之前所使用的频点不同，这样，所述用户终端在接收到所述RRC连接释放命令之后。所述用户终端可以通过异频频点搜索对应的小区，以恢复由于无线环境较差造成的语音单通。
需要说明的是，可选的，所述基站的PDCP层收到的所述用户终端的VoLTE数据包的总数等于第一阈值的情况和/或所述基站的PDCP层收到的所述用户终端的VoLTE数据包的错包率大于第二阈值的情况也可以增加至步骤301中，本发明实施例对此不做限定。可选的，所述SINR等于第一预设值，所述MCS等于第二预设值，所述基站MAC层接收到的所述用户终端的VoLTE数据包的错包率等于第三预设值，所述基站RLC层接收到的所述用户终端的VoLTE数据包的总数等于第四预设值，这四个情况中的任一种情况都可以增加至步骤302或者步骤303，本发明实施例对此不做限定。
需要说明的是，在本发明实施例中步骤301和步骤302是作为必要步骤，而步骤303可以作为可选步骤；可以理解的是，由于步骤302和步骤303介绍的是两种不可能同时存在的情况，因此，在一种可行的实施例中，步骤301和步骤303可以作为必要步骤，而步骤302作为可选步骤，这一可行的实施例中每个步骤的具体执行过程可参见图3所示实施例，在此不再赘述。
在本发明实施例中，在检测周期内用户终端存在QCI为1的连接但基站的PDCP层收到的用户终端的VoLTE数据包较多但错包率较高的情况下，表示用户终端在检测周期内出现了语音单通的问题，进一步若根据检测周期内的 用户终端的SINR、MCS、基站MAC层接收到的用户终端的VoLTE数据包的错包率、基站RLC层接收到的用户终端的VoLTE数据包的总数确定用户终端当前所处的小区的无线环境较好，向用户终端发送小区内切换命令，这样用户终端可以通过重新配置无线承载继续在该小区中通信，以使基站的PDCP层能够收到较多的用户终端的VoLTE数据包，因此这样能够及时解决用户终端的语音单通问题，提高用户的语音通信质量。
