Description

一种流量统计方法、装置及终端设备 技术领域
本发明涉及通信领域，尤其涉及一种流量统计方法、装置及终端设备。

随着社会发展，使用手机上网已越来越普遍。在用户通过手机上网时，会产生一定的流量，上网产生的流量可以通过手机系统自带的流量统计功能，或者通过手机上安装的第三方软件统计得到，以方便用户查询。
在现有技术中，由于数据业务采用的协议栈部署在手机的应用处理器(Application processor，AP)侧，因此在统计用户上网产生的流量时，不论是手机系统自带的流量统计功能，还是手机上安装的第三方软件，均是基于手机的AP来实现的，也就是说，手机的AP可以对上网产生的流量进行统计，并通过手机系统自带的流量统计功能或者手机上安装的第三方软件展示给用户。众所周知，随着移动通信技术的发展，长期演进(Long Term Evolution，LTE)网络应运而生，LTE网络不仅可以为用户提供高速率的数据业务，还可以通过采用基于LTE的语音(英文：Voice Over LTE，简称：VoLTE)技术为用户提供高质量的音视频业务，这样当用户使用LTE网络进行音视频通话时，也会产生一定的流量。

具体实施方式
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，本领域普通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。
众所周知，在统计用户上网产生的流量时，由于数据业务采用的协议栈部署在用户设备的AP侧，因此基于AP可以实现对用户上网产生的流量的统计。随着通信技术的不断发展，LTE网络越来越普及，LTE网络不仅可以为用户提供高速率的数据业务，还可以通过采用VoLTE技术为用户提供高质量的音视频业务，但由于音视频业务采用的(IP Multimedia Subsystem，IMS)协议栈一般情况下部署在用户设备的调制解调器(Modem)侧，这样便会导致基于AP无法实现对用户使用音视频业务产生的流量的统计。本发明提供的流量统计方法能够实现对用户使用音视频业务过程中产生的流量的统计，其中具体的实现过程通过以下实施例进行详细介绍。
需要说明的是，本发明实施例中所述的用户设备可以为手机、平板电脑(portable android device，PAD)等手持设备。
本发明一实施例提供一种流量统计方法，如图1所示，该方法可以包括：
101、当Modem检测到第一互联网协议(Internet Protocol，IP)报文时，获取第一IP报文的第一IP地址，并获取第一IP报文的报文长度。
其中，当第一IP报文为Modem接收到的报文时，该第一IP地 址为第一IP报文的源IP地址，当第一IP报文为Modem需发送给网络侧的报文时，该第一IP地址为第一IP报文的目标IP地址。
102、Modem从内存数据库中获取与第一IP报文的第一IP地址对应的接入点名称(Access point name，APN)。
其中，内存数据库中存储有至少一个IP地址以及与每个IP地址对应的APN。在Modem获取到第一IP报文的第一IP地址之后，可以将该第一IP报文的第一IP地址与内存数据库中存储的IP地址进行匹配，以便从内存数据库中获取与该第一IP报文的第一IP地址对应的APN。
103、当与第一IP报文的第一IP地址对应的APN为第一公共数据网络(Public Data Network，PDN)的APN时，Modem将第一IP报文的报文长度累加到VoLTE流量的第一统计值中。
其中，第一PDN为建立VoLTE业务的承载所需的PDN。

进一步的，为了能够使得Modem确定出检测到的IP报文的报文长度是否需统计到VoLTE流量中，在步骤101中所述的Modem检测到第一IP报文之前，本发明实施例提供的流量统计方法还可以包括：Modem获取第一PDN的IP地址，并将第一PDN的IP地址和第一PDN的APN对应存储在内存数据库中。

进一步的，Modem获取AP统计得到的VoLTE流量的第二统计值，在一种可能的实现方式中，具体的可以为：Modem接收AP发送的VoLTE流量的第二统计值。

进一步的，对于在VoLTE流量存在限制的情况下，为了在能够不影响用户使用音视频业务的前提下，节省用户的流量，本发明实施例提供的流量统计方法还包括：Modem确定VoLTE流量的第一统计值是否大于或等于VoLTE流量的限制值；当VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，Modem根据切换策略传输VoLTE业务，其中，VoLTE业务为VoLTE语音业务或VoLTE视频业务。
需要说明的是，在本发明实例例中，在采用IMS协议栈的VoLTE业务均部署在Modem侧的情况下，Modem用于确定VoLTE流量是否大于或等于VoLTE流量的限制值时采用的第一统计值为步骤103中Modem统计得到的第一统计值；在采用IMS协议栈的VoLTE业务部署在Modem侧和AP侧的情况下，Modem用于确定VoLTE流量是否大于或等于VoLTE流量的限制值时采用的第一统计值为将AP统计得到的VoLTE流量的第二统计值累加到VoLTE流量的第一统计值之后得到的第一统计值。
进一步的，在Modem确定VoLTE流量的第一统计值是否大于或等于VoLTE流量的限制值之前，本发明实施例提供的流量统计方法还包括：Modem接收AP发送的VoLTE流量的限制值。
进一步的，为了在VoLTE流量存在限制的情况下，可以根据用 户的选择调整VoLTE业务的传输方案，在Modem根据切换策略传输VoLTE业务之前，本发明实施例提供的流量统计方法还包括：Modem接收AP发送的切换策略，其中，切换策略是AP接收到用户对切换策略的选择触发后发送的。
进一步的，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，VoLTE语音业务和VoLTE视频业务的传输均不受限制；Modem根据切换策略传输VoLTE业务，具体的可以为：

其中，Modem从LTE网络切换到2G/3G网络，并将采集到的语音数据通过CS域进行传输，指的就是电路交换回退(Circuit  Switched FallBack，CSFB)技术。
当VoLTE业务为VoLTE视频业务时，Modem将视频模式切换为语音模式，并将采集到的语音数据通过CS域或PS域进行传输。
进一步的，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，降低VoLTE语音业务的编解码速率，降低VoLTE视频业务的传输参数；Modem根据切换策略传输VoLTE业务，具体的可以为：

其中，第一PDN为建立VoLTE业务的承载所需的PDN。
具体的，针对在LTE网络下为用户提供的数据业务和VoLTE业务，运营商很有可能制定不同的收费标准，在这种情况下，需要将用户使用数据业务产生的流量和使用VoLTE业务产生的流量分别进行统计，因此在AP从内存数据库中获取到与该第二IP报文的第二IP地址对应的APN之后，AP可以判断与该第二IP报文的第二IP地址对应的APN是否为建立VoLTE业务的承载所需的PDN的APN，即第一PDN的APN，并在确定出与该第二IP报文的第二IP地址对应的APN为第一PDN的APN之后，AP将获取到的第二IP报文的报文长度累加到VoLTE流量的第二统计值中。

303、AP获取Modem统计得到的VoLTE流量的第一统计值。
其中，为了确保能够统计到用户使用用户设备过程中产生的所有流量，AP还需获取Modem统计得到的VoLTE流量的第一统计值。
进一步的，在一种可能的实现方式中，步骤303具体可以为：AP接收Modem发送的VoLTE流量的第一统计值。或者，在另一种可能的实现方式中，步骤303具体可以为：AP查询Modem统计的流量数据获得VoLTE流量的第一统计值。

在AP从内存数据库中获取到与第二IP报文的第二IP地址对应的APN之后，为了能够确定出传输该第二IP报文产生的流量是VoLTE流量还是数据流量，AP可以判断获取到的与该第二IP报文的第二IP地址对应的APN是建立VoLTE业务的承载所需的PDN的APN，即第一PDN的APN，还是建立数据业务的承载所需的PDN的APN，即第二PDN的APN时。
410、当与第二IP报文的第二IP地址对应的APN为第一PDN的APN时，AP将第二IP报文的报文长度累加到VoLTE流量的第二统计值中。

进一步的，在执行步骤411之后，AP还可以判断统计到的数据流量的统计值是否大于或等于用户设置的数据流量的限制值，并在数据流量的统计值大于或等于用户设置的数据流量的限制值时，对需要传输的数据进行限制。
需要说明的是，在本发明实施例中步骤401-步骤405与步骤406-步骤411的执行顺序没有先后关系。
在本发明实施例中，进一步的，对于在VoLTE流量存在限制的情况下，为了在能够不影响用户使用音视频业务的前提下，节省用户的流量，在采用IMS协议栈的VoLTE业务均部署在Modem侧的情况下，在执行步骤405之后，可以直接执行步骤414-步骤417，但考虑到采用IMS协议栈的某些VoLTE业务可能会部署在AP侧，因此在执行步骤414之前，还需执行步骤406-步骤413。

417、Modem根据切换策略传输VoLTE业务。
其中，VoLTE业务为VoLTE语音业务或VoLTE视频业务。当VoLTE流量的第一统计值大于或等于VoLTE流量的限制值，Modem接收AP发送的切换策略之后，当此时有VoLTE业务需要传输时，Modem此时需根据用户选择的切换策略传输该VoLTE业务。
在一种可能的实现方式中，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，VoLTE语音业务和VoLTE视频业务的传输均不受限制。此时，Modem根据切换策略传输VoLTE业务，具体的可以是：当VoLTE业务为VoLTE语音业务时，Modem将采集到的语音数据通过LTE网络进行传输；当VoLTE业务为 VoLTE视频业务时，Modem将采集到的语音数据和图像数据通过LTE网络进行传输。
在另一种可能的实现方式中，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，VoLTE语音业务的传输不受限制，VoLTE视频业务的传输受限。此时，Modem根据切换策略传输VoLTE业务，具体的可以是：当VoLTE业务为VoLTE语音业务时，Modem将采集到的语音数据通过LTE网络进行传输；当VoLTE业务为VoLTE视频业务时，Modem将视频模式切换为语音模式，并将采集到的语音数据通过LTE网络进行传输。
在另一种可能的实现方式中，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，VoLTE语音业务和VoLTE视频业务的传输均受限。此时，Modem根据切换策略传输VoLTE业务，具体的可以为：当VoLTE业务为VoLTE语音业务时，从LTE网络切换到第2G/3G网络，并将采集到的语音数据通过CS域或PS域进行传输；当VoLTE业务为VoLTE视频业务时，Modem将视频模式切换为语音模式，并将采集到的语音数据通过CS域或PS域进行传输。当然，当VoLTE流量的第一统计值小于VoLTE流量的限制值，如，重新对VoLTE流量进行了统计时，需重新将用户设备的VoLTE功能开启。
在另一种可能的实现方式中，切换策略为在VoLTE流量的第一统计值大于或等于VoLTE流量的限制值时，降低VoLTE语音业务的编解码速率，降低VoLTE视频业务的传输参数。此时，Modem根据切换策略传输VoLTE业务，具体的可以为：当VoLTE业务为VoLTE语音业务时，Modem降低采集到的语音数据的编解码速率。
其中，采用自适应多速率窄带编码(Adaptive Multi-Rate-Narrowband，AMR-NB对语音数据进行编码时，不同编码模式的编解码速率参见表1所示，采用自适应多速率宽带编码(Adaptive Multi-Rate-Wideband，AMR-WB)对语音数据进行编码时，不同编码模式的编解码速率参见表2所示。
表1
编码模式 编解码速率
0 4.75kbps
1 5.15kbps
2 5.90kbps
3 6.70kbps
4 7.40kbps
5 7.95kbps
6 10.20kbps
7 12.20kbps
表2
编码模式 编解码速率
0 6.60kbps
1 8.85kbps
2 12.65kbps
3 14.25kbps
4 15.85kbps
5 18.25kbps
6 19.85kbps
7 23.05kbps
8 23.85kbps
由表1和表2可以看出，在当前对语音数据进行编解码采用的编解码方式为AMR-NB的情况下，当VoLTE流量的第一统计值大于或等于VoLTE流量的限制值，且VoLTE业务为VoLTE语音业务时，Modem可以在当前的编码方式下通过改变编码模式，以达到降低采集到的语音数据的编解码速率的目的，例如，当前采用的编码模式为4(对应的编解码速率为7.40kbps)，那么当VoLTE流量的第一统计值大于或等于VoLTE流量的限制值之后，需要进行传输的语音数据均采用编码模式2进行编解码，也就是说，采用5.90kbps的编 解码速率对语音数据进行编解码。
在当前对语音数据进行编解码采用的编解码方式为AMR-WB的情况下，不仅可以通过在当前的编码方式下通过改变编码模式，以达到降低采集到的语音数据的编解码速率的目的，还可以通过改变当前的编码方式，以达到降低采集到的语音数据的编解码速率的目的，例如，当前的编码模式为2(对应的编解码速率为12.65kbps)，那么当VoLTE流量的第一统计值大于或等于VoLTE流量的限制值之后，需要进行传输的语音数据可以采用当前编码方式下的编码模式1(对应的编解码速率为8.85kbps)进行编解码，也可以将当前的编码方式为AMR-NB，并采用AMR-NB编码方式下的编码模式7(对应的编解码速率为12.20kbps)进行编解码。
需要说明的是，在当前对语音数据进行编解码采用的编解码方式为AMR-WB的情况下，具体降低采集到的语音数据的编解码速率采用的方式可以根据实际应用场景的需求进行选择，并预先设置在Modem中，本发明实施例在此对降低采集到的语音数据的编解码速率采用的具体方式不做具体限制。
当VoLTE业务为VoLTE视频业务时，Modem降低采集到的视频数据的传输参数，其中，视频数据的传输参数包括以下一种或多种：视频数据中的图像数据的分辨率、视频数据中的图像数据的帧率，视频数据中的语音数据编解码速率。
进一步的，还可以通过SDP协商，使得与自身进行通信的远端设备也降低采集到的视频数据中的图像数据的分辨率和/或视频数据中的图像数据的帧率。
需要说明的是，降低采集到的视频数据中的语音数据编解码速率可以参考本发明实施例中降低采集到的语音数据的编解码速率的具体描述，本发明实施例在此不再详细赘述。
需要说明的是，本发明实施例中的切换策略也可以是Modem确定网络发生拥塞的情况下，自动选择出的；还可以是在VoLTE流量未达到VoLTE流量的限制值的情况下，用户为了节省流量直接选择 触发后由AP发送至Modem的。
进一步的，为了能够将统计得到的VoLTE流量显示给用户，供用户查询，如图5所示，若采用IMS协议栈的VoLTE业务部署在Modem侧和AP侧，在执行步骤411之后，还可以包括以下步骤418-步骤420。
418、AP获取Modem统计得到的VoLTE流量的第一统计值。
其中，AP获取Modem统计得到的VoLTE流量的第一统计值可以包括两种方式。
方式一、AP接收Modem发送的VoLTE流量的第一统计值。
其中，Modem可以周期性的上报自身统计到的VoLTE流量的第一统计值，以便AP可以接收Modem发送的VoLTE流量的第一统计值。
方式二、AP查询Modem统计的流量数据获得VoLTE流量的第一统计值。
其中，AP可以主动对Modem统计的流量数据进行查询，以获得Modem统计到的VoLTE流量的第一统计值。
419、AP将VoLTE流量的第一统计值累加到VoLTE流量的第二统计值中。
其中，在AP获取到Modem统计得到的VoLTE流量的第一统计值之后，可以将VoLTE流量的第一统计值累加到VoLTE流量的第二统计值中，以获得产生的所有VoLTE流量。

当然，若采用IMS协议栈的VoLTE业务均部署在Modem侧，为了能够将统计得到的VoLTE流量显示给用户，那么在执行步骤405 之后，执行步骤418，并直接将获取到的VoLTE流量的第一统计值显示给用户，以便将VoLTE流量显示给用户供用户查询。
进一步的，在本发明实施例中，还可以对用户在某一次通话过程中产生的VoLTE流量进行统计，即在用户的本次通话过程中，重复执行步骤403-步骤405，以得到用户在本次通话过程中产生的VoLTE流量，并可以通过将统计得到的本次通话过程中产生的VoLTE流量的第一统计值发送至AP，以便AP将本次通话过程中产生的VoLTE流量显示给用户。
进一步的，在本发明实施例中，还可以将传输VoLTE语音业务产生的VoLTE流量和传输VoLTE视频业务产生的VoLTE流量分别进行统计。在一种应用场景下，当建立VoLTE语音业务承载的所需的PDN与建立VoLTE视频业务承载的所需的PDN相同，且均为第一PDN时，在执行步骤404之后，若与第一IP报文的第一IP地址对应的APN为第一PDN的APN时，可以继续判断传输该第一IP报文的端口的端口号，当传输该第一IP报文的端口的端口号为传输VoLTE语音业务的端口的端口号时，将第一IP报文的报文长度累计到VoLTE语音流量的统计值中，当传输该第一IP报文的端口的端口号为传输VoLTE视频业务的端口的端口号时，将第一IP报文的报文长度累计到VoLTE视频流量的统计值中。在另一种应用场景下，当建立VoLTE语音业务承载的所需的PDN与建立VoLTE视频业务承载的所需的PDN不相同，则可以在执行步骤404之后，直接判断与第一IP报文的第一IP地址对应的APN是建立VoLTE语音业务承载的所需的PDN的APN，还是建立VoLTE视频业务承载的所需的PDN的APN，当与第一IP报文的第一IP地址对应的APN是建立VoLTE语音业务承载的所需的PDN的APN时，将第一IP报文的报文长度累计到VoLTE语音流量的统计值中，当与第一IP报文的第一IP地址对应的APN是建立VoLTE视频业务承载的所需的PDN的APN时，将第一IP报文的报文长度累计到VoLTE视频流量的统计值中。当然，还可以针对每个应用，进程统计其对应的流量，以达到分别统计， 分别限制的目的。
本发明实施例提供的流量统计方法，当Modem检测到第一IP报文时，根据获取到的第一IP报文的第一IP地址，从内存数据库中获取与该第一IP报文的第一IP地址对应的APN，并在与该第一IP报文的第一IP地址对应的APN为建立VoLTE业务的承载所需的PDN的APN时，将获取到的第一IP报文的报文长度累加到VoLTE流量的第一统计值中，以实现对VoLTE流量的统计，这样针对现有技术中仅能统计到AP侧的流量相比，实现了在用户使用LTE网络进行音视频通话时产生的流量的统计。
并且，当AP检测到第二IP报文时，根据获取到的第二IP报文的第二IP地址，从内存数据库中获取与该第二IP报文的第二IP地址对应的APN，并在与该第二IP报文的第二IP地址对应的APN为建立VoLTE业务的承载所需的PDN的APN时，将获取到的第二IP报文的报文长度累加到VoLTE流量的第二统计值中，当该第二IP报文的第二IP地址对应的APN为建立数据业务的承载所需的PDN的APN时，将获取到的第二IP报文的报文长度累加到数据流量的统计值中，以实现对数据流量和VoLTE流量分别统计，且在此基础上，可以针对数据流量和VoLTE流量分别进行限制，以避免误限的情况发生。且在VoLTE流量存在限制的情况下，在能够不影响用户使用音视频业务的前提下，节省了用户的流量。且提供的多种切换策略供用户选择，这样在VoLTE流量存在限制的情况下，可以根据用不选择进行VoLTE业务的传输，提高了用户体验。
本发明另一实施例提供一种流量统计方法，如图6所示，该方法可以包括：
501、Modem获取第一PDN的IP地址。
502、Modem将第一PDN的IP地址和第一PDN的APN对应存储在内存数据库中。
503、当Modem检测到第一IP报文时，获取第一IP报文的第一IP地址，并获取第一IP报文的报文长度。
504、Modem从内存数据库中获取与第一IP报文的第一IP地址对应的APN。
在Modem从内存数据库中获取到与第一IP报文的第一IP地址对应的APN之后，为了能够确定出传输该第一IP报文产生的流量是否是VoLTE流量，Modem可以判断获取到的与该第一IP报文的第一IP地址对应的APN是否为建立VoLTE业务的承载所需的PDN的APN，即第一PDN的APN。
505、当与第一IP报文的第一IP地址对应的APN为第一PDN的APN时，Modem将第一IP报文的报文长度累加到VoLTE流量的第一统计值中。
其中，当Modem确定出获取到的与该第一IP报文的第一IP地址对应的APN不是建立VoLTE业务的承载所需的PDN的APN，即与第一IP报文的第一IP地址对应的APN不是第一PDN的APN时，Modem不做任何处理。
506、AP检测到第二IP报文时，获取第二IP报文的报文长度。
507、AP将第二IP报文的报文长度累加到流量的统计值中。
508、AP获取Modem统计得到的VoLTE流量的第一统计值。
进一步的，在一种可能的实现方式中，步骤508具体可以为：AP接收Modem发送的VoLTE流量的第一统计值。或者，在另一种可能的实现方式中，步骤508具体可以为：AP查询Modem统计的流量数据获得VoLTE流量的第一统计值。
509、AP将VoLTE流量的第一统计值累加到流量的统计值中。
其中，在AP获取到Modem统计得到的VoLTE流量的第一统计值之后，可以将获取到的将VoLTE流量的第一统计值累加到流量的统计值中，以实现对用户使用用户设备时产生的所有流量的统计。进一步的，在AP还可以将统计到的流量统计值显示给用户，以方便用户查询。
需要说明的是，在本发明实施例中，AP向用户显示的流量统计值为AP将Modem统计得到的VoLTE流量的第一统计值累加到流量 统计值之后得到的流量统计值。
