- the method may specifically include the following steps:
- Step 101 When the voice service is established, start receiving voice data.
- the RNC when the RNC receives the connection confirmation message Connect-Ack sent by the non-access stratum (NAS), the voice service is established, and the voice data is started to be received. The detection of the voice service is terminated when the service is released or the handover between the RNCs occurs.
- the service request may be released (IU RELEASE COMPLETE) core network initiated release service, or service request RNC initiates release (IU RELEASE REQUEST) 0

- SQI statistics whether to perform UE SQI tracking depends on whether the user starts QOS tracking, and the QOS tracking measurement configures the required quality measurement, and the "QoS tracking configuration quality measurement is set to SQI function" switch is enabled in the global algorithm. For example, if there are 10 cells in an RNC, 9 of them need to be enabled, but 1 cell (cell A) does not need to enable this function. Therefore, under the parameter configuration, the 9 cells are measured. This cell does not measure;
- the cell SQI statistics and the SQI statistics of the UE are performed, and whether the UE SQI tracking is performed depends on whether the user starts QOS tracking, and the QOS tracking measurement configures the required quality. Measure, and the "Quality measurement of QoS tracking configuration is set to SQI function" switch is turned on in the global algorithm.
- the RNC has enabled the SQI function globally and the SQI function of the cell is enabled as follows:
- the RNC uses the formula to obtain the user-level uplink and downlink SQIs in each cycle (8S), and after the call ends, obtains an average of the SQIs for the entire process of the call. The results are added to the CDL at the performance statistics level for background analysis.

- the specific voice single-pass detection steps are as follows:
- condition 1 a large number of packet loss occurs
- condition 2 a large proportion occurs
- condition 2 a large proportion occurs
- the decision condition of the voice single pass in the actual network may need to be adjusted, the decision threshold, that is, the parameters of the algorithm may be configured as needed;

- the voice single-pass detection method is used to notify the maintenance personnel that the voice single-pass phenomenon has occurred in the device at the first time when the voice single-pass phenomenon occurs, which needs to be processed in time. Reducing the recovery time of the failure may solve the problem of the voice single pass before the VIP VIP user complains. It realizes the monitoring of voice quality and whether the voice single-pass problem occurs, timely discovers the voice single-pass phenomenon, reduces the fault recovery time, improves the security and stability of the voice service, and improves the user communication experience.

本申请实施例提供的一种在其上记录有用于执行权利要求 1 所述方 法的程序的计算机可读记录介质。 与现有技术相比, 本申请包括以下优点:
本申请实施例针对 TD-SCDMA网络进行语音单通的检测, 在语音业
务建立完成后, 对接收到的语音数据按照预设周期进行检测, 依据接收 到的语音数据是否丟失语音数据, 或者接收到的错误语音数据是否大于 预设阈值来判断是否出现语音单通, 可实现对语音质量、 是否发生语音 单通问题进行监控, 及时发现语音单通现象, 减少了故障处理恢复时间, 提升了语音业务的安全性与稳定性, 提高了用户通信的体验效果。 另外, 本申请实施例时在语音业务建立完成之后, 才对语音业务进行单通检测, 由于在用户开始正式通话后才开始进行语音业务的单通检测, 因此可以 避免在在用户实际通话之前进行语音单通检测而导致误检或漏检的情 况。 附图说明

为使本申请的上述目的、 特征和优点能够更加明显易懂, 下面结合 附图和具体实施方式对本申请作进一步详细的说明。
为使本领域技术人员更好地理解本申请, 以下对 "语音单通" 简单 说明:
目前, 可以将发生语音单通的现象定义为: 单向语音不通、 双向语 音不通以及串话。 可能会让用户认为 "语音单通" 的原因罗列如下:
1、 某个方向(上行 /下行)一段时间内确实无语音数据 (;包括静默帧);
2、 某个方向(上行 /下行)一段时间内只有静默帧, 没有真正的语音数
据;
3、 某个方向(上行 /下行)一段时间内网络能接收到语音数据, 但是错 误帧占到一定比例 (给用户的感觉是噪音, 无法听清楚对方声音);
4、 由于非正常挂机等操作导致用户误认为语音单通(譬如已经删除 RADIO LINK (无线链路), 但是用户终端没有释放, 用户终端显示仍然 是正在通话, 会给用户突然发生了语音单通的感觉)。
针对上述归纳的四大类发生语音单通的原因进一步分析, 可能造成 语音单通的原因罗列如下:
A: 核心通信网络( Core Network, CN ) 原因;
无线网络控制器 ( Radio Network Controller, RNC ) 从 CN接收不到 或接收到大量错误的语音数据或只能收到静默的语音数据 (静默帧) 等 情况;
B: 终端自身原因;
基站 (Node Base, NodeB )从对应码道上接收不到终端数据或解调 后的语音数据大量错误或只能收到静默的语音数据等情况;
C: 空口 (UU接口) 原因和接入网原因。
空口质量差导致传输的语音质量差, 在空口中存在例如无线干扰、 弱覆盖、 无主覆盖等无线质量差的情况造成语音质量差。
在实际中, 需要将 A、 B、 C这三种原因结合起来考虑, 单纯的空口 质量差导致语音数据大量丟失或者错误可以通过 RNC或终端的接收数据 分析进行判定。 但对于譬如载波调整、 切换、 状态跃迁过程中由于接入 网自身实现纰漏, 更容易导致语音单通的发生, 这时候很可能空口质量 不错且传输无故障, 这点从外场客服反馈中能得到证实。 本申请实施例的核心构思之一在于, 针对 TD-SCDMA网络进行语音 单通的检测, 在语音业务建立完成后, 对接收到的语音数据按照预设周 期进行检测, 依据接收到的语音数据是否丟失语音数据, 或者接收到的 错误语音数据是否大于预设阈值来判断是否出现语音单通, 可实现对语
音质量、 是否发生语音单通问题进行监控, 及时发现单通现象, 减少故 障处理恢复时间。
参照图 1 ,示出了本申请一种语音业务单通检测的方法实施例 1的步 骤流程图, 所述方法具体可以包括如下步骤:
步骤 101 , 当语音业务建立完成时, 开始接收语音数据;
在具体实现中, 当 RNC接收到非接入层( Non Access Stratum, NAS ) 发送的连接确认消息 Connect-Ack时, 语音业务建立完成, 开始接收到语 音数据。当业务释放或者发生 RNC间的切换后终止对该语音业务的检测。 其中, 所述业务释放可以是核心网发起的业务释放的请求(IU RELEASE COMPLETE ) , 或者是 RNC 发起的业务释放的请求 ( IU RELEASE REQUEST )0
步骤 102, 若按照预设周期检测到所述语音业务满足预设条件, 则判 定所述语音业务出现语音单通; 其中, 所述预设条件包括: 丟失的语音 数据达到预设丟失阈值, 或者, 错误的语音数据达到预设错误阈值。
在本申请实施例中, 可以在 RNC下设置语音单通检测的开关, 小区 下可以设置有控制是否开启语音单通检测的开关。
如果 RNC 下的语音单通检测方法有效 (至少配置 1种方法), 当小区 下语音单通检测开关开启时, 对该小区新接入用户进行语音单通检测; 当小区下单通检测开关关闭时, 对该小区新接入用户不进行语音单通检 测。
如果 RNC 下的语音单通检测方法都关闭(所有方法都不使用), 则 RNC下所有小区无论语音单通检测开关是否开启都不进行单通检测。
需要说明的是, 对于 RNC下语音单通检测方法的修改, 仅针对修改 后小区新接入的用户有效。 对于小区下语音单通检测方法的修改, 仅针 对修改后小区新接入的用户有效。
在本申请的一种优选实施例中,当所述预设条件为丟失的语音数据达 到预设丟失阈值时, 所述步骤 102可以包括如下子步骤:
子步骤 S11 , 在预设周期中检测在同一传输方向上, 是否连续在第一
预设个数的传输时间间隔 ( transmission time interval, TTI ) 没有接收到 语音数据; 若是, 则执行子步骤 S12;
子步骤 S12, 获取第一报告统计值; 其中, 所述第一报告统计值为基 站在预设周期中在同一方向上, 连续没有接收到语音数据的 ΤΉ的个数; 子步骤 S13 , 若所述第一报告统计值与所述第一预设个数一致, 则判 定所述语音业务出现疑似语音单通;
子步骤 S14, 在预设周期中检测在同一传输方向上, 是否连续在第二 预设个数的 ΤΉ没有接收到语音数据; 若是, 则执行子步骤 S15;
子步骤 S15 , 获取第二报告统计值;
子步骤 S16, 若所述第二报告统计值与所述第二预设个数一致, 则判 定所述语音业务出现语音单通。
在具体实现中, 可以按照预设周期进行语音业务的单通检测, 由于用 户感知到的语音单通时间往往是秒级的, 并且语音数据包本身的周期是 20ms„ 因此, 可以选择预设周期为 2秒, 那么在一个检测周期内满包为 100个语音数据包。
在本申请的一种优选实施例中,所述丟失的语音数据可以包括上行传 输通路或下行传输通路中正确的语音数据, 错误的语音数据以及静默的 语音数据;
具体地, 丟失的语音数据可以包括上行传输通路, 或者, 下行传输通 路中正确的语音数据 (语音帧), 错误的语音数据 (错误的语音帧) 以及 静默的语音数据(静默帧)。 RNC对于每个语音业务分别统计其上行传输 通路及下行传输通路各自连续无语音数据的 ΤΉ个数。 假设 RNC接收到 用户说话方发送的是语音帧, 那么 RNC接收到用户听话方发送的就是静 默帧, 因此, 分别统计其上行传输通路及下行传输通路各自连续无语音 数据的 ΤΉ个数方法可以包括:
1、 无语音帧检测
若在预设周期检测到在连续多个 ΤΉ无语音帧事件并通过 呼叫数据 记录 ((Call Detail Logs, CDL )进行上报。 RNC对每个语音业务分别统计
其上行传输通路及下行传输通路各自连续无语音帧接收的 ΤΉ个数。 RNC 上报统计的无语音帧接收的 ΤΉ 个数达到某一门限并不能确认此时就是 语音单通,还需要以消息形式通知 NodeB, 让 NodeB上 ^艮其 4艮告统计值, 统计在预设周期中 NodeB连续无语音帧接受的 ΤΉ的个数, RNC对每个 语音业务分别统计其上行传输通路及下行传输通路各自连续无语音帧接 收的 ΤΉ个数。
例如, 当在预设周期无语音帧接收的 ΤΉ个数达到第一预设个数时, 通过 CDL进行上报, 并向 NodeB发送 "语音单通检测指示" 消息指示其 统计第一报告统计值; 当 NodeB收到 RNC下发的 "语音单通检测指示" 消息后,收集在预设周期无语音帧的个数的第一报告统计值发送给 RNC。 RNC判断第一报告统计值与第一预设个数是否一致,若是,则判定为 "疑 似语音单通";根据 NodeB上报的语音单通检查报告中的内容进行进一步 判断通过 CDL进行上报; 当连续无数据接收的 ΤΉ个数达到第二预设个 数时通过 CDL进行上报,并向 NodeB发送消息指示其上报第二报告统计 值; RNC判断第二报告统计值与第二预设个数是否一致, 若是, 则判定 为 "语音单通"。 其中, 检测语音单通发生的预设阈值可以由 OMC-R (操 作维护中心) 进行配置。
2、 静默帧检测
若在检测连续多个 ΤΉ 除了静默帧之外没有其它语音帧事件并通过 CDL进行上报。 RNC对每个语音业务分别统计其上行传输通路及下行传 输通路各自连续接收静默帧的 ΤΉ个数。 RNC上报统计的连续接收静默 帧的 ΤΉ 个数达到某一门限并不能确认此时就是语音单通, 还需要以消 息形式通知 NodeB, 让 NodeB上 ^艮其 4艮告统计值, 进行进一步的印证。
例如, 当在预设周期连续接收到静默帧的 ΤΉ 个数达到第一预设个 数时, 通过 CDL进行上报, 并向 NodeB发送 "语音单通检测指示" 消息 指示其统计第一报告统计值; 当 NodeB收到 RNC下发的 "语音单通检测 指示" 消息后, 收集在预设周期连续接收静默帧的 ΤΉ 个数的第一报告 统计值发送给 RNC; RNC判断第一报告统计值与第一预设个数是否一致 ,
若是, 则判定为 "疑似语音单通"; 当连续接收静默帧的 ΤΉ个数达到第 二预设个数时通过 CDL进行上报,并向 NodeB发送消息指示其第二报告 统计值, RNC判断第二报告统计值与第二预设个数是否一致, 若是, 则 判定为 "语音单通"。
在实际中, 当检测到出现 "疑似语音单通" 或者出现 "语音单通" 时, 可以通过告警、 事件日志的形式告诉维护人员, 设备可能或者已经 发生了语音单通, 需要及时处理, 维护人员可以依据实际情况是否进行 相关设备的维护或修理, 可大大减少故障的处理恢复时长, 可能会在 VIP 贵宾用户发生投诉之前就已经及时解决了语音单通的问题, 提升了语音 业务的安全性与稳定性, 提高了用户通信的体验效果。
作为本申请的一种优选示例, 在判决是否发生语音单通的依据条件 可以为发生大量语音数据包丟包, 具体可以进行如下统计:
Num—UL— Speech— Good + Num—UL— Speech— Bad + Num—UL— Silence *
8 < 90;〃根据协议中规定的语音静默时序, 当进入稳态后一个静默桢后续 要跟 7个空包;
其中, Num—UL— Speech— Good 可以表示为上行语音正确包数目, Num—UL— Speech— Bad可以表示为上行语音错误包数目, Num—UL— Silence 可以表示为上行静默包数目。 当在上行传输通路中全部丟失的语音数据 超过 90个时, 可以认为出现了语音单通。
需要说明的是, 上述代码是针对上行传输通路检测语音单通, 下行 传输通路与上行传输通路的处理方法可以相同。 参照图 2,示出了本申请一种语音业务单通检测的方法实施例 2的步 骤流程图, 所述方法具体可以包括如下步骤:
步骤 201 , 当语音业务建立完成时, 开始接收语音数据;
步骤 202, 若按照预设周期检测到所述语音业务满足预设条件, 则判 定所述语音业务出现语音单通; 其中, 所述预设条件包括: 丟失的语音 数据达到预设丟失阈值, 或者, 错误的语音数据达到预设错误阈值。
在本申请的一种优选实施例中,当所述预设条件为错误的语音数据达 到预设错误阈值时, 所述步骤 202可以包括如下子步骤:
子步骤 S21 , 统计在预设周期接收到错误的语音数据;
子步骤 S22, 计算所述错误的语音数据占所述接收的语音数据的比 率;
子步骤 S23 , 若所述比率大于预设比率阈值, 则判定所述语音业务出 现语音单通。
在本申请的一种优选实施例中,所述错误的语音数据可以包括上行传 输通路或下行传输通路中错误的语音数据。
在本申请实施例中,用户终端从载波上接收到物理信号但不能正确解 出 CRC (循环冗余码校验)认为此块语音数据错误,计入到误块率(Block Error Ratio, BLER ) 中。 误块产生的原因, 可能是终端自身硬件故障、 空口传输质量、 基站覆盖等。
具体地, 可以检测在预设周期内用户上 4艮的语音业务 BLER 的平均 值, 由于目前现网对 BLER上报周期较长, 故当 RNC 收到用户上报的 BLER值到某个门限则直接该语音业务出现 "语音单通", 通过 CDL进行 上报。 语音单通发生的门限值由 RNC操作维护中心 ( RNC Operation and Maintenance Center, OMC-R ) 进行配置。 考虑到避免误报的情况, 建议 该值不要配置过小。
在本申请实施例中, RNC根据用户终端 (User Equipment, UE ) 的 测量上报,获得下行的 BLER(误块率),根据信号质量指数( Signal Quality Index, SQI )公式的参数, RNC计算出下行 SQI, 然后 RNC根据 TPSS (业务处理子系统) 的测量上报;
RNC 获得上行的 BLER、 最长连续帧差错 ( the longest consecutive sequence of frame Error, LFE ), 根据 SQI公式的参数, RNC计算出上行 SQI; 根据上述结果, RNC计算得到用户级别的上、 下行 SQI, 放置在性 能统计级别的 CDL中; RNC计算得到小区级别的上、 下行 SQI, 通过性 能统计方式上报给 OMC;
对于 VIP贵宾用户, RNC可以进行服务质量( Quality of Service, QoS ) 跟踪, 将计算的上、 下行 SQI, 通过 CDL进行上报。
其中, RNC的 QoS跟踪功能启动的判断如下:
如果全局算法中的 SQI测量数配置为 0,则说明整个 RNC不开启 SQI 功能(包括小区 SQI和 UE SQI统计和跟踪)。
如果全局算法中的 SQI 测量数配置为 2(即上行 BLER 测量、 下行 BLER测量), 但是某个小区不开启 SQI功能: 则在这个小区下不进行小 区 SQI统计, 也不进行这个小区下 UE的 SQI统计, 是否进行 UE SQI跟 踪, 取决于用户是否开启 QOS跟踪, 且 QOS跟踪测量配置了需要的质 量测量, 且全局算法中 "QoS跟踪配置的质量测量是否设置为 SQI功能" 开关开启。 比如一个 RNC下有 10个小区, 其中 9个小区需要开启该功 能, 但有 1 个小区 (小区 A ) 不需要开启该功能, 所以在这种参数配置 下, 对那 9个小区进行测量, 对这一个小区不进行测量;
如果全局算法开启了 SQI功能, 且某个小区开启 SQI功能, 则进行 小区 SQI统计和 UE的 SQI统计, 是否进行 UE SQI跟踪, 取决于用户是 否开启 QOS跟踪, 且 QOS跟踪测量配置了需要的质量测量, 且全局算 法中 "QoS跟踪配置的质量测量是否设置为 SQI功能" 开关开启。
RNC在全局开启了 SQI功能、 小区开启 SQI功能前提如下:
RNC根据针对用户的 BLER LFE统计结果, 在每个周期(8S)内, 利 用公式, 得到用户级别的上、 下行 SQI, 并且在通话结束后, 得到一个对 通话整个过程的 SQI进行平均值,其结果添加到性能统计级别的 CDL中 , 供后台分析。
在本申请的一种优选示例中, 判决是否发生语音单通的依据条件可 以为发生大比例的语音数据包错包, 具体可以进行如下统计:
Num—UL— Speech— Bad/(Num—UL— Speech— Good+N UL— Speech— Ba d) > 30%;〃当接收到的语音数据包总数低于某个门限时,可以让本公式暂 时失效;
其中, 当上行传输通路的错误的语音数包据所占语音数据包的比例
大于 30%时, 可以认为出现语音单通。 参照图 3 ,示出了本申请一种语音业务单通检测的方法实施例 3的步 骤流程图, 所述方法具体可以包括如下步骤:
步骤 301 , 当语音业务建立完成时, 开始接收语音数据;
步骤 302, 若按照预设周期检测到所述语音业务满足预设条件, 则判 定所述语音业务出现语音单通; 其中, 所述预设条件包括: 丟失的语音 数据达到预设丟失阈值, 或者, 错误的语音数据达到预设错误阈值。
步骤 303 , 输出所述语音业务出现语音单通的错误类型; 所述错误类 型包括: 上行语音丟包单通,上行语音错包单通, 下行语音丟包单通以及 下行语音错包单通。
在本申请实施例中, 针对语音业务的相关语音数据统计可以包括: 上行语音正确包数目(Num—UL— Speech— Good);
上行语音错误包数目(Num—UL— Speech— Bad);
上行静默包数目(Num—UL— Silence);
下行语音正确包数目(Num—DL— Speech— Good);
下行语音错误包数目(Num—DL— Speech— Bad);
下行静默包数目(Num—DL— Silence)。
当语音业务单通检测完成后, 可以输出语音业务出现语音单通的错 误类型, 即进行输出相关的话务统计:
上行话务统计: 上行语音丟包单通, 上行语音错包单通;
下行话务统计: 下行语音丟包单通, 下行语音错包单通。
另外, 当语音业务单通检测完成后, 还可以输出发生语音单通前 5 个周期数据接收情况, 罗列如下:
发生语音单通前 5个周期的 FP上行接收包数目 (结合物理层(MAC ) 接收包数目, 监测 Iub接口数据包传输的故障);
发生语音单通前 5个周期的 MAC上行接收包数目;
发生语音单通前 5个周期的 MAC上行接收错误包数目。
以及,
发生语音单通前 5个周期的 IUUP下行接收包数目;
发生语音单通前 5个周期的 MAC下行接收包数目;
发生语音单通前 5个周期的 MAC下行接收错误包数目。 为了使本领域技术人员进一步了解本申请实施例, 下面通过一个具 体的示例来说明本申请进行语音业务单通检测的过程。
在现有方案中检测语音单通可以通过算法来检测语音单通, 该算法 的应用场景可以是针对每个 AMR业务流单独检测, 由于上下行数据流是 完全独立处理的, 因此, 语音单通检测算法也上下行分开各自单独工作。
参照图 4所示本申请的一种语音单通检测方案及算法示意图,具体的 语音单通检测步骤如下:
1 , 当 AMR语音业务建立完成后, 接收收到 NAS (非接入层) 消息 Connect- Ack, 算法启动;
2, 当算法启动后, 进行周期性检测, 由于用户感知到的单通时间往 往是秒级的, 又因为语音数据包本身的周期是 20ms, 因此, 可以将检测 周期选择为 2秒, 在一个检测周期内满包为 100个数据包;
3 ,检测 AMR语音业务是否满足条件 1或条件 2; 在实际问题分析中 发现, 有两种情况下均可能被用户认为单通, 条件 1 , 发生大量数据包丟 包; 条件 2, 发生大比例的数据包错包, 因此将这两种情况作为语音单通 的检测条件。 由于实际网络中语音单通的判决条件可能需要调整, 因此 判决门限, 即算法的参数可按需要进行配置;
4, 若检测到发生语音单通, 在 RNC话统中输出单通话统指标 (RNC 级), 该话统包括 4个指标, 分别是上行丟包单通, 上行错包单通, 下行 丟包单通, 下行错包单通;
5 , 在检测到语音单通时, 在 RNC 内部输出相关打点, 即相关的统 计结果;
6, 当业务释放或者发生 RNC间切换后算法终止。
本申请实施例通过上述语音单通的检测方法,在语音单通现象发生的 第一时间, 通过告警、 事件日志的形式告诉维护人员, 设备已经发生语 音单通现象, 需要及时处理, 这样可大大减少故障的处理恢复时长, 可 能会在 VIP贵宾用户发生投诉之前就已经解决了语音单通的问题。 实现 了对语音质量、 是否发生语音单通问题的监控, 及时发现语音单通现象, 减少了故障处理恢复时间, 提升了语音业务的安全性与稳定性, 提高了 用户通信的体验效果。
另外,本申请实施例是在语音业务建立完成后, 即用户开始正式通话 后才开始进行语音业务的单通检测, 因此可以避免在在用户实际通话之 前进行语音单通检测而导致误检或漏检的情况。
需要说明的是, 对于方法实施例, 为了简单描述, 故将其都表述为 一系列的动作组合, 但是本领域技术人员应该知悉, 本申请并不受所描 述的动作顺序的限制, 因为依据本申请, 某些步骤可以采用其他顺序或 者同时进行。 其次, 本领域技术人员也应该知悉, 说明书中所描述的实 施例均属于优选实施例, 所涉及的动作并不一定是本申请所必须的。 参照图 5,示出了本申请一种语音业务单通检测的装置实施例的结构 框图, 所述装置具体可以包括如下模块:
