Description

一种资源调度方法和装置
本申请要求在2014年4月2日提交中国专利局、申请号为201410132354.1、发明名称为“一种资源调度方法和装置”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
本发明涉及通信技术领域,特别涉及一种资源调度方法和装置。
背景技术
长期演进(Long Term Evolution,LTE)网络是一个全因特网协议(Internet Protocol,IP)化的网络,因此,承载语音业务也需要通过基于互联网协议的话音(Voice over IP,VoIP)的方式进行承载,VoIP是一种可以在IP网络上传输模拟音讯或视讯的一种技术,其基本原理是:通过语音压缩算法,对语音数据进行语音压缩编码处理,然后把处理后的数据按照IP等相关协议进行打包,经过IP网络把数据包传输到接收端;接收端把接收到的数据包串起来,经过解码解压处理后,恢复成原来的语音信号,从而达到通过IP网络传输语音的目的。
按照第三代合作伙伴计划(The 3rd Generation Partnership,3GPP)协议描述,半持续调度(Semi-Persistent Scheduling,SPS)可以应用于VoIP这种数据包大小和数据包发送间隔都比较稳定的业务资源分配,具体VoIP业务源模型如图1所示。现有SPS调度方案是针对12.2kbps编码速率的语音业务,当检测到业务进入激活期时,通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)下发SPS资源激活指示,在VoIP业务激活期期间VoIP业务的初传数据使用分配的SPS半持续资源传输,重传数据包使用动态调度的资源分配方式传输,并且在VoIP业务激活期期间已经分配的SPS半持续资源不会发生改变;当检测到业务进入静默期时,通过显式(即PDCCH指示)或者隐的方式进行SPS资源去激活,对VoIP业务静默期的数据包采用动态调度的资源分配方式传输。
现有SPS调度方案在VoIP业务激活期期间,网络侧为用户设备(User Equipment,UE)所配置的SPS资源是不会发生改变。该激活期期间,若用户设备上行、下行信道发生变化,如果不及时调整该用户设备所使用的资源,将会降低用户体验。如当前用户设备的信道条件相比激活SPS资源时的信道质量更好,此时,传输有效数据所需要的SPS半持续资源会更少,如果不及时调整该用户设备所使用的资源,势必造成资源的浪费,使系统不能接入更多的用户,降低了用户体验;又如,当用户设备的信道条件相比激活SPS资源时信道质量变差,此时,传输有效数据需要的SPS半持续资源需要增多,如果不及时调整该用户设备所使用的资源,就会出现数据传输错误概率增大,传输时延加大,降低了用户体验。
综上所述,现有SPS调度方案在VoIP业务激活期期间,若用户设备上/下行信道发生变化,会造成用户体验降低的问题。

具体实施方式
本发明通过每个设定的调整周期结束后,根据在该调整周期内获取到的用户设备的信道质量信息和/或与该用户设备的数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源,并在调整了该用户设备所使用的SPS资源,将调整后的SPS资源通知给该用户设备,从而可以在用户设备已分配的SPS资源的激活期内,灵活的调整该用户设备所使用的SPS资源,提高了用户体验,增大了用户容量。
下面结合说明书附图对本发明实施例作进一步详细描述。应当理解,此处所描述的实施例仅用于说明和解释本发明,并不用于限定本发明。
本发明实施例提供的一种资源调度方法,参见图2所示,该方法包括:
步骤21、针对每个传输VoIP业务的用户设备,在用户设备传输VoIP业务所使用的SPS资源被激活后,在每个设定的调整周期内,获取该用户设备的信道质量信息和/或与该用户设备的数据传输相关的信息。
本步骤中,与用户设备的数据传输相关的信息包括但不限于以下信息中的至少一个种:
用于传输用户设备的VoIP业务的承载的块误码率(Block Error Rate,BLER);
用于传输用户设备的VoIP业务的承载的数据传输频谱效率;
用户设备的有效数据传输比率,其中,有效数据传输比率用于表示用户设备正确接收到的数据包中携带的有效VoIP数据与接收到的总数据的比例。
步骤22、针对每个传输VoIP业务的用户设备,每个设定的调整周期结束后,根据用户设备的信道质量信息和/或与该用户设备的数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源。
本步骤中,本发明实施例不对判断处理可以在设定的调整周期结束后任意时刻执行判断处理。
步骤23、针对每个传输VoIP业务的用户设备,若确定需要调整该用户设备所使用的SPS资源,调整该用户设备所使用的SPS资源,并将调整后的SPS资源通知给该用户设备。
在实施时,上述方法的执行主体为基站,也可以为其他网络实体。
本发明实施例提供的方法可以在用户设备已分配的SPS资源的激活期内,灵活的调整 该用户设备所使用的SPS资源,从而提高了用户体验,增大了用户容量。
在实施中,作为一种优选的实现方式,步骤21具体为:针对每个传输VoIP业务的用户设备,在该用户设备传输VoIP业务所使用的SPS资源被激活后,启动用于进行SPS资源调整的定时器,在该定时器定时期间,获取用户设备的信道质量信息和/或与用户设备的数据传输相关的信息;
相应的,步骤22具体为:针对每个传输VoIP业务的用户设备,在该定时器超时时,根据获取到的用户设备的信道质量信息和/或与用户设备的数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源。
该优选方式下,该方法进一步还包括:在确定不需要调整用户设备所使用的SPS资源或完成用户设备所使用的SPS资源的调整后,再次启动定时器,并在定时器定时期间,获取用户设备的信道质量信息和/或与用户设备的数据传输相关的信息。
本发明实施例并不限于采用上述优选的实现方式,步骤21和步骤22还可以采用其他方式实现,例如,步骤21具体为:针对每个传输VoIP业务的用户设备,从上一次调整后的SPS资源的激活时刻(若当前为第一次调整,此处为SPS资源首次激活时刻)开始,获取用户设备的信道质量信息和/或与用户设备的数据传输相关的信息;相应的,步骤22具体为:针对每个传输VoIP业务的用户设备,在当前时刻与该用户设备上一次调整后的SPS资源的激活时刻的差值大于设定的时间戳后,根据获取到的用户设备的信道质量信息和/或与用户设备的数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源。
在实施中,步骤22中,根据用户设备的信道质量信息和/或与该用户设备的数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源,具体包括以下几种方式:
方式1、仅根据用户设备的信道质量信息,判断是否需要调整该用户设备所使用的SPS资源。
该方式下,步骤21具体为:针对每个传输VoIP业务的用户设备,在每个设定的调整周期内,获取用户设备上报的信道质量指示(Channel Quality Indicator,CQI)信息对应的调制编码方式(Modulation and Coding Scheme,MCS)等级(index)。
相应的,步骤22具体为:针对每个传输VoIP业务的用户设备,每个调整周期结束后,根据获取到的MCS等级(记为MCS_index_New)和该用户设备已分配的SPS资源的MCS等级(记为MCS_index),判断是否需要调整该用户设备所使用的SPS资源。
进一步,根据获取到的MCS等级和该用户设备已分配的SPS资源的MCS等级,判断是否需要调整该用户设备所使用的SPS资源,具体包括:
在获取到的MCS等级与用户设备已分配的SPS资源的MCS等级的差值的绝对值不大于设定的偏移量时,确定不需要调整该用户设备所使用的SPS资源;
或者,在获取到的MCS等级与用户设备已分配的SPS资源的MCS等级的差值的绝对 值大于所述偏移量时,确定需要调整该用户设备所使用的SPS资源。
该方式下,步骤23中,在确定需要调整用户设备所使用的SPS资源时,调整该用户设备所使用的SPS资源,具体包括:
在获取到的MCS等级减去用户设备已分配的SPS资源的MCS等级的差值大于设定的偏移量时,确定减少该用户设备所使用的SPS资源分配的物理资源块(Physical Resource Block,PRB)的数量;或者,
在用户设备已分配的SPS资源的MCS等级减去获取到的MCS等级的差值大于设定的偏移量时,确定增加该用户设备所使用的SPS资源分配的PRB的数量。
举例说明,假设调整周期内获取到的用户设备上报的CQI对应MCS等级为MCS_Index_New;该用户设备已分配的SPS资源的MCS等级为MCS_Index,判断是否需要调整该用户设备所使用的SPS资源具体如下:
如果abs(MCS_Index_New-MCS_Index)≤alfa_1,即MCS等级变化不大,则不作任何操作,即不需要调整该用户设备所使用的SPS资源;
否则,如果MCS_Index_New>MCS_Index+alfa_1,则说明可以减少SPS资源分配的PRB个数;如果MCS_Index_New<MCS_Index-alfa_1,则说明需要增加SPS资源分配的PRB个数。
该方式下,步骤23中,将调整后的SPS资源通知给用户设备,包括:通过“PDCCHwith SPS-CRNTI NDI=0”的UL grant(上行调度)或者DL assignment(下行配置)内容重新指示调整后的SPS资源,在该UL grant或者该DL assignment中携带调整后的SPS资源和获取到的MCS等级(即MCS_Index_New)。其中,PDCCH为物理下行控制信道(Physical Downlink Control Channel)的缩写;SPS-CRNTI为半持续调度小区无线网络临时标识(Semi-Persistent Scheduling-CRNTI,SPS-CRNTI;Cell-Radio Network Temporary Identifier,C-RNTI)的缩写;NDI为新数据指示(New Data Indicator)的缩写。
该方式下,调整周期内获取到的用户设备上报的CQI信息可以是该调整周期内至少一次CQI信息的滤波平滑值,也可以是距离该调整周期到达时刻最近一次上报的CQI信息;较佳地,调整周期内获取到的用户设备上报的CQI信息可以是修正后的值,并且不考虑在本SPS资源上传输的修正影响。
方式2、仅根据与该用户设备的数据传输相关的信息中的一种信息,判断是否需要调整该用户设备所使用的SPS资源。
该方式下,步骤22具体为:针对每个传输VoIP业务的用户设备,每个调整周期结束后,根据本调整周期内获取到的与该用户设备数据传输相关的信息与上一个调整周期内获取到的与该用户设备数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源。
进一步,根据本调整周期内获取到的与用户设备数据传输相关的信息与上一个调整周期内获取到的与用户设备数据传输相关的信息,判断是否需要调整该用户设备所使用的SPS资源,包括:
在本调整周期内获取到的与用户设备数据传输相关的信息与上一个调整周期内获取到的与用户设备数据传输相关的信息的差值的绝对值不大于与该用户设备数据传输相关的信息对应的阈值时,确定不需要调整该用户设备所使用的SPS资源;
或者,
在本调整周期内获取到的与用户设备数据传输相关的信息与上一个调整周期内获取到的与用户设备数据传输相关的信息的差值的绝对值大于与所述用户设备数据传输相关的信息对应的阈值时,确定需要调整该用户设备所使用的SPS资源。
在实施中,该方式进一步包括:
方式2a、与用户设备数据传输相关的信息为用于传输该用户设备的VoIP业务的承载的BLER。
该方式下,步骤22具体为:针对每个传输VoIP业务的用户设备,每个调整周期结束后,根据本调整周期内获取到的BLER与上一个调整周期内获取到的BLER,判断是否需要调整该用户设备所使用的SPS资源。
进一步,在本调整周期内获取到的BLER与上一个调整周期内获取到的BLER的差值的绝对值不大于设定的BLER对应的阈值时,确定不需要调整该用户设备所使用的SPS资源;或者,
在本调整周期内获取到的BLER与上一个调整周期内获取到的BLER的差值的绝对值大于设定的BLER对应的阈值时,确定需要调整该用户设备所使用的SPS资源。
进一步,步骤23中,在确定需要调整用户设备所使用的SPS资源时,调整该用户设备所使用的SPS资源,包括:
在本调整周期内获取到的BLER减去上一个调整周期内获取到的BLER的差值大于设定的BLER对应的阈值时,确定增加用户设备所使用的SPS资源分配的PRB的数量并下调该用户设备当前所使用的SPS资源的MCS等级;或者,
在上一个调整周期内获取到的BLER减去本调整周期内获取到的BLER的差值大于设定的BLER对应的阈值时,确定减少用户设备所使用的SPS资源分配的PRB的数量并上调该用户设备当前所使用的SPS资源的MCS等级。
举例说明,假设当前调整周期内获取到的VoIP业务承载的数据传输的BLER为BLER_New,上一个调整周期内获取到的VoIP业务承载的数据传输的BLER为BLER:
如果绝对值abs(BLER_New–BLER)≤alfa_2,即两个调整周期统计的BLER相差不大,则不作任何操作;
否则,如果BLER_New>BLER+alfa_2,则说明当前使用的SPS资源对应的MSC等级过高,需要下调,同时需要增加SPS资源分配的PRB个数;如果BLER_New<BLER-alfa_2,则说明当前使用的SPS资源对应的MSC等级过低,需要上调,同时可以减少SPS资源分配的PRB个数。
该方式下,较佳地,在调整周期内获取到的BLER为该调整周期内至少一次BLER的平均值。
该方式下,BLER对应的阈值取大于或等于0的值,具体取值精度取决于统计的BLER的精度和VoIP业务的剩余BLER要求,需要小于VoIP业务的剩余BLER要求,初步建议可以是10-e3量级。
需要说明的是,在用户设备的SPS资源被激活后的第一个调整周期内仅统计当前分配的SPS资源下的VoIP业务承载的数据传输BLER,不做调整处理;其后的每一个调整周期结束后,将本调整周期内统计的结果与前一个调整周期统计的结果进行比较判断。
该方式下,步骤23中,将调整后的SPS资源通知给用户设备,包括:通过“PDCCH with SPS-CRNTI NDI=0”的UL grant(上行调度)或者DL assignment(下行配置)内容重新指示调整后的SPS资源,在该UL grant或者该DL assignment中携带调整后的SPS资源和调整后的MCS等级。
方式2b、与用户设备数据传输相关的信息为用于传输用户设备的VoIP业务的承载的数据传输频谱效率。
该方式下,步骤22具体为:针对每个传输VoIP业务的用户设备,每个调整周期结束后,根据本调整周期内获取到的频谱效率与上一个调整周期内获取到的频谱效率,判断是否需要调整该用户设备所使用的SPS资源。
进一步,在本调整周期内获取到的数据传输频谱效率与上一个调整周期内获取到的频谱效率的差值的绝对值不大于频谱效率对应的阈值时,确定不需要调整该用户设备所使用的SPS资源;或者,
在本调整周期内获取到的频谱效率与上一个调整周期内获取到的频谱效率的差值的绝对值大于频谱效率对应的阈值时,确定需要调整该用户设备所使用的SPS资源。
进一步,步骤23中,在确定需要调整用户设备所使用的SPS资源时,调整该用户设备所使用的SPS资源,包括:
在本调整周期内获取到的频谱效率减去上一个调整周期内获取到的频谱效率的差值大于设定的频谱效率对应的阈值时,确定减少用户设备所使用的SPS资源分配的PRB的数量并上调该用户设备当前所使用的SPS资源的MCS等级;或者,
在上一个调整周期内获取到的频谱效率减去本调整周期内获取到的频谱效率的差值大于设定的频谱效率对应的阈值时,确定增加用户设备所使用的SPS资源分配的PRB的 数量并下调该用户设备当前所使用的SPS资源的MCS等级。
举例说明,假设当前调整周期内获取到的VoIP业务承载的数据传输频谱效率为eff_New,前一调整周期内获取到的VoIP业务承载的数据传输频谱效率为eff,则:
如果绝对值abs(eff_New–eff)<alfa_3,即两个调整周期统计的数据传输频谱效率相差不大,则不作任何操作;
否则,如果eff_New>eff+alfa_3,则说明当前使用的SPS资源对应的MSC等级过低,需要上调,同时需要减少SPS资源分配的PRB个数;如果eff_New<eff-alfa_3,则说明当前使用的SPS资源对应的MSC等级过高,需要下调,同时可以增加SPS资源分配的PRB个数。
该方式下,较佳地,在调整周期内获取到的频谱效率为该调整周期内统计的至少一次频谱效率的结果的平均值。
需要说明的是,在用户设备的SPS资源被激活后的第一个调整周期内仅统计当前分配的SPS资源下的VoIP业务承载的数据传输频谱效率,不做调整处理;其后的每一个调整周期结束后,将本调整周期内统计的结果与前一个调整周期统计的结果进行比较判断。
该方式下,频谱效率对应的阈值取大于或等于0的值,具体取值精度取决于统计的频谱效率的精度和VoIP业务期望的频谱效率精度要求,需要小于VoIP业务期望的频谱效率精度,初步建议可以是10-e3量级。
该方式下,步骤23中,将调整后的SPS资源通知给用户设备,包括:通过“PDCCH with SPS-CRNTI NDI=0”的UL grant(上行调度)或者DL assignment(下行配置)内容重新指示调整后的SPS资源,在该UL grant或者该DL assignment中携带调整后的SPS资源和调整后的MCS等级。
方式2c、与用户设备数据传输相关的信息为用户设备的有效数据传输比率,其中,有效数据传输比率用于表示用户设备正确接收到的数据包中携带的有效VoIP数据与接收到的总数据的比例,即正确接收到的数据包中携带的有效VoIP数据bit数除以数据包的bit数(即传输块大小(TB size))。
该方式下,步骤22具体为:针对每个传输VoIP业务的用户设备,每个调整周期结束后,根据本调整周期内获取到的有效数据传输比率与上一个调整周期内获取到的有效数据传输比率,判断是否需要调整该用户设备所使用的SPS资源。
进一步,在本调整周期内获取到的有效数据传输比率与上一个调整周期内获取到的有效数据传输比率的差值的绝对值不大于设定的有效数据传输比率对应的阈值时,确定不需要调整该用户设备所使用的SPS资源;或者,
在本调整周期内获取到的有效数据传输比率与上一个调整周期内获取到的有效数据传输比率的差值的绝对值大于设定的有效数据传输比率对应的阈值时,确定需要调整该用 户设备所使用的SPS资源。
进一步,步骤23中,在确定需要调整用户设备所使用的SPS资源时,调整该用户设备所使用的SPS资源,包括:
在本调整周期内获取到的有效数据传输比率减去上一个调整周期内获取到的有效数据传输比率的差值大于设定的有效数据传输比率对应的阈值时,确定减少该用户设备所使用的SPS资源分配的PRB的数量并上调该用户设备当前所使用的SPS资源的MCS等级;或者,
在上一个调整周期内获取到的有效数据传输比率减去本调整周期内获取到的有效数据传输比率的差值大于设定的有效数据传输比率对应的阈值时,确定增加该用户设备所使用的SPS资源分配的PRB的数量并下调该用户设备当前所使用的SPS资源的MCS等级。
举例说明,假设当前调整周期内获取到的VoIP业务承载的有效数据传输比率为ratio_New,前一调整周期内获取到的VoIP业务承载的有效数据传输比率为ratio,则:
如果绝对值abs(ratio_New–ratio)≤alfa_4,即两个调整周期统计的有效数据传输比率相差不大,则不作任何操作;
否则,如果ratio_New>ratio+alfa_4,则说明当前使用的SPS资源对应的MSC等级过高,需要下调,同时需要增加SPS资源分配的PRB个数;如果ratio_New<ratio-alfa_4,则说明当前使用的SPS资源对应的MSC等级过低,需要上调,同时可以减少SPS资源分配的PRB个数。
该方式下,较佳地,在调整周期内获取到的有效数据传输比率为该调整周期内统计的至少一次有效数据传输比率的结果的平均值。
需要说明的是,在用户设备的SPS资源被激活后的第一个调整周期内仅统计当前分配的SPS资源下的VoIP业务承载的有效数据传输比率,不做调整处理;其后的每一个调整周期结束后,将本调整周期内统计的结果与前一个调整周期统计的结果进行比较判断。
该方式下,有效数据传输比率对应的阈值取大于或等于0的值,具体取值精度取决于统计的有效数据传输比率的精度,初步建议可以是10-e3量级。
该方式下,步骤23中,将调整后的SPS资源通知给用户设备,包括:通过“PDCCH with SPS-CRNTI NDI=0”的UL grant(上行调度)或者DL assignment(下行配置)内容重新指示调整后的SPS资源,在该UL grant或者该DL assignment中携带调整后的SPS资源和调整后的MCS等级。
方式3、根据用户设备的信道质量信息和与该用户设备的数据传输相关的信息中的至少一种信息,判断是否需要调整该用户设备所使用的SPS资源。
该方式下,根据用户设备的信道质量信息判断是否需要调整该用户设备所使用的SPS资源,具体参见方式1的描述,此处不再赘述;根据用户设备的数据传输相关的信息中的 至少一种信息,判断是否需要调整该用户设备所使用的SPS资源,具体参见上述参见方式2a~方式2c的描述,此处不再赘述。
该方式下,若根据用户设备的信道质量信息得到的判断结果与根据与用户设备的数据传输相关的信息得到的判断结果不同,将根据用户设备的信道质量信息得到的判断结果作为最终的判断结果。即:当出现判断结果冲突时,根据用户设备的信道质量信息得到的判断结果的优先级高于根据与用户设备的数据传输相关的信息得到的判断结果。
方式4、根据与该用户设备的数据传输相关的信息中的至少两种信息,判断是否需要调整该用户设备所使用的SPS资源。
该方式下,根据用户设备的数据传输相关的信息中的至少一种信息,判断是否需要调整该用户设备所使用的SPS资源,具体参见上述参见方式2a~方式2c的描述,此处不再赘述。
该方式下,若根据用于传输用户设备的VoIP业务的承载的BLER得到的判断结果,与根据用于传输用户设备的VoIP业务的承载的数据传输频谱效率的判断结果和/或根据用户设备的有效数据传输比率的判断结果不同,将根据用于传输用户设备的VoIP业务的承载的BLER得到的判断结果作为最终的判断结果;
若根据用于传输用户设备的VoIP业务的承载的数据传输频谱效率的判断结果与根据用户设备的有效数据传输比率的判断结果不同,将根据用于传输用户设备的VoIP业务的承载的数据传输频谱效率的判断结果作为最终的判断结果。
该方式下,当出现判断结果冲突时,采用方式2a得到的判断结果的优先级高于采用方式2b得到的判断结果的优先级,且采用方式2b得到的判断结果的优先级高于采用方式2c得到的判断结果的优先级。
基于上述任一实施例,步骤23中,在确定需要调整用户设备所使用的SPS资源时,调整该用户设备所使用的SPS资源,包括:
在确定需要调整用户设备所使用的SPS资源时,根据该用户设备传输的VoIP业务的语音编码速率,调整该用户设备所使用的SPS资源。
在实施中,该方法还包括:根据用户设备传输的VoIP业务的语音编码速率,确定该用户设备传输VoIP业务初始所使用的SPS资源。即初始为用户设备分配SPS资源时,也需要根据该用户设备传输的VoIP业务的语音编码速率,为该用户设备配置SPS资源。
基于上述任一实施例,根据以下方式确定用户设备传输的VoIP业务的语音编码速率:
方式一、根据用于传输所述用户设备的VoIP业务的承载对应的最大比特速率(Maximum Bit Rate,MBR)参数,确定该用户设备传输的VoIP业务的语音编码速率。
该方式下,利用VoIP业务承载配置的MBR参数直接判别。具体为:
如果MBR是自适应多速率宽带编码(Adaptive Multi-rate-Wideband,AMR-WB) 23.85kbps,则确定用户设备当前VoIP业务承载编码方式为AMR-WB;
如果MBR是自适应多速率窄带编码(Adaptive Multi-rate-Narrow Band,AMR-NB)12.2kbps,则确定用户设备当前VoIP业务承载编码方式为AMR-NB。
方式二、根据监测到的用户设备的上行VoIP业务和/或下行VoIP业务的数据包的大小,确定该用户设备传输的VoIP业务的语音编码速率。
该方式下,可以将检测到的上行VoIP业务(即用户设备上行发送的VoIP业务)和下行VoIP业务(即发送给用户设备下行接收的VoIP业务)的数据包一起统计,也可以上行VoIP业务和下行VoIP业务的数据包分别统计(即上行/下行两个方向分别统计)。对于两个方向分别统计的方式,只要一个方向确定出了编码速率,另一个方向也确定为相同的编码速率,即确定编码速率后,可以同时停止两个方向的统计过程。
该方式下,在设定的监测周期(VoIPAMRModeCheckTime)内,监测到的用户设备的上行VoIP业务和/或下行VoIP业务的数据包的大小(size)小于设定的门限值时,将用于统计AMR-NB的第一计数器加1;和/或,监测到的用户设备的上行VoIP业务和/或下行VoIP业务的数据包的大小不小于该门限值时,将用于统计AMR-WB的第二计数器加1;
在该监测周期内,若第一计数器的值不小于设定的阈值,则确定所述用户设备传输的VoIP业务的语音编码速率为AMR-NB;或者,若第二计数器的值不小于设定的阈值,则确定用户设备传输的VoIP业务的语音编码速率为AMR-WB。
进一步,若在该监测周期内,第一计数器的值小于设定的阈值且第二计数器的值小于设定的阈值,则在该监测周期结束后,根据第一计数器的值与第二计数器的值,确定用户设备传输的VoIP业务的语音编码速率。
具体的,若第一计数器的值大于第二计数器的值,则确定该用户设备传输的VoIP业务的语音编码速率为AMR-NB;或者,
若第一计数器的值不大于第二计数器的值,则确定该用户设备传输的VoIP业务的语音编码速率为AMR-WB。
举例说明,启动VoIP业务承载编码速率识别定时器VoIPAMRModeCheckTime,分别初始化检测到的AMR-NB数据包n1个(即第一计数器)以及AMR-WB数据包n2个(即第二计数器)。记录VoIP激活期接收到的数据包大小为voip_active_packet_size(对于下行,即为语音承载对应buffer每次新增的数据量大小)。在VoIP业务承载编码速率识别定时器VoIPAMRModeCheckTime有效期间,执行如下判断流程:
如果VoIP激活期接收到的数据包大小voip_active_packet_size<VoIPAMRModePacketSizeThreshold(即设定的阈值),则更新n1加1。进一步,如果n1≥VoIPAMRModeCheckPacketNumber,则确定VoIP业务承载编码方式VoIPAMRMode为AMR-NB,终止VoIP业务承载编码速率识别定时器VoIPAMRModeCheckTime,复位相关 记录变量;否则,不作任何操作,继续后续处理。
如果VoIP激活期接收到的数据包大小voip_active_packet_size≥VoIPAMRModePacketSizeThreshold,则更新n2加1。进一步,如果n2≥VoIPAMRModeCheckPacketNumber,则确定VoIP业务承载编码方式VoIPAMRMode为AMR-WB,终止VoIP业务承载编码速率识别定时器VoIPAMRModeCheckTime,复位相关记录变量;否则,不作任何操作,继续后续处理。
当VoIP业务承载编码速率识别定时器VoIPAMRModeCheckTime超时时,若n1<VoIPAMRModeCheckPacketNumber,且n2<VoIPAMRModeCheckPacketNumber,则执行如下判断流程:
如果n1>n2,则确定VoIP业务承载编码方式为AMR-NB;
否则,即n1≤n2,则确定VoIP业务承载编码方式为AMR-WB。
在实施中,方式一和方式二可以单独使用(即仅采用方式一或方式二确定用户设备传输的VoIP业务的语音编码速率),也可以同时使用(即采用方式一和方式二同时确定用户设备传输的VoIP业务的语音编码速率),较佳地,若根据用于传输用户设备的VoIP业务的承载对应的MBR参数确定出的该用户设备传输的VoIP业务的语音编码速率,与根据接收到的用户设备的VoIP业务的数据包的大小确定出的该用户设备传输的VoIP业务的语音编码速率不同,将根据用于传输用户设备的VoIP业务的承载对应的MBR参数确定出的用户设备传输的VoIP业务的语音编码速率,作为该用户设备传输的VoIP业务的最终语音编码速率。即当上述方式一喝方式二得到的结果发生冲突时,采用方式一得到的结果的优先级比采用方式二得到的结果的优先级高。
上述方法处理流程可以用软件程序实现,该软件程序可以存储在存储介质中,当存储的软件程序被调用时,执行上述方法步骤。
