Description
本发明涉及移动通信领域的资源调度管理技术,尤其涉及一种补偿调度方法、装置及计算机存储介质。
网络电话(VoIP,Voice over Internet Protocol)业务采用IP数据传输技术,无需2G/3G网络支持,VoIP业务可以承载于长期演进(LTE,Long Term Evolution)网络上;由于语音用户很多、且语音业务具有周期性发包的特点,每次传输时都需要发送相关的控制信息,所以控制信息的开销很大;针对这类数据包大小相对比较固定,到达时间间隔满足一定规律的实时性业务,通常采用半静态调度(SPS,Semi-persistence Scheduling)技术,以减小控制信息的开销;SPS技术是指为特定业务设计的、在固定时刻使用预先分配的资源,而在其他时刻采用动态调度(重传)机制的一种调度方法;具体地,SPS启动后,系统将指定的资源块周期性地分配给指定的用户,以适应某些周期性的、有效载荷大小固定的业务,从而达到减少资源分配、指示等信息带来的系统开销,而SPS技术的数据重传则采用动态调度的方法。
现有技术中,基站通过向用户设备(UE,User Equipment)发送包含特定信息的下行控制信息(DCI0,Downlink Control Information format0)来激活上行SPS业务;UE识别到用于激活SPS的DCI0时,保存当前的调度信息,按照SPS的配置,间隔固定的周期使用预先配置的时频资源进行语音包的发送。
然而,实际上并不是每一个语音业务数据包的包头长度一样,现有技
术中SPS预先配置的资源无法满足语音数据包的资源需求,从而导致语音数据包不能及时传输;如此,会增大调度时延及丢包率,无法保证业务服务质量,影响用户体验。
发明内容
有鉴于此,本发明实施例期望提供一种补偿调度方法、装置及计算机存储介质,能降低调度时延及丢包率,保证业务服务质量,改善用户体验。

本发明实施例提供了一种计算机存储介质,所述计算机存储介质中存储有计算机程序,所述计算机程序用于执行以上所述的补偿调度方法。
本发明实施例提供的补偿调度方法、装置及计算机存储介质,当根据UE在SPS周期点发送的缓冲区状态报告(BSR,Buffer Status Report)确定预设条件满足时,向UE发送包括补偿调度资源的动态资源分配消息,以使UE使用所述补偿调度资源传输所述BSR对应的业务数据包,从而将业务数据包及时发送;如此,能极大地降低了调度时延及丢包率,保证了业务服务质量,进而可改善用户体验。
图1为本发明实施例提供的补偿调度方法的流程图;
图2为本发明实施例提供的补偿调度装置的结构图。
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。
图1为本发明实施例提供的补偿调度方法的流程图,如图1所示,该方法包括:
步骤101、接收UE在SPS周期点发送的BSR。
这里,本发明实施例提供的补偿调度方法可以应用于采用SPS调度技术的场景中,举例来说,所述补偿调度方法可以应用于LTE系统中针对VoIP业务的SPS调度场景。本发明实施例提供的补偿调度方法的执行主体可以为补偿调度装置,所述补偿调度装置可以设置于网络接入设备的内部,也可以独立于网络接入设备单独配置,其中,所述网络接入设备可以为基站等;为方便理解,下面以基站为例进行说明;UE在上行SPS周期点使用预先分配的资源、通过物理上行共享信道(PUSCH,Physical Uplink Shared Channel)向基站发送BSR;基站接收UE发送的BSR;所述BSR可以反映UE还需发送的业务数据包的大小等信息。
步骤102、根据所述BSR确定预设条件满足时,向所述UE发送包括补偿调度资源的动态资源分配消息,所述动态资源分配消息用于使所述UE使用所述补偿调度资源传输所述BSR对应的业务数据包。
这里,基站接收到UE在SPS周期点发送的BSR后,若根据所述BSR确定预设条件满足时,则基站进行一次动态调度;具体地,基站根据所述BSR确定需要的补偿调度资源,然后向所述UE发送包括补偿调度资源的动态资源分配消息;所述UE接收所述包括补偿调度资源的动态资源分配消息,所述UE使用所述补偿调度资源传输所述BSR对应的业务数据包。
本发明实施例提供的补偿调度方法,在半静态调度的基础上,当根据UE在SPS周期点发送的BSR确定预设条件满足时,向UE发送包括补偿调度资源的动态资源分配消息,以使UE使用所述补偿调度资源传输所述BSR对应的业务数据包,从而实现将业务数据包及时发送;如此,能极大地降低了调度时延及丢包率,保证了业务服务质量,进而可改善用户体验。
实际中,VoIP业务数据包可以包括:实时传输协议(RTP,Real-time Transport Protocol)包、RTP控制协议(RTCP,RTP Control Protocol)包,
所述RTP包即语音包,所述RTP包与所述RTCP包都映射在服务质量等级标识(QCI1,Quality of Service Class Identifier 1)承载上。现有技术中,SPS预先配置的资源是按照RTP包的大小进行计算的,当基站激活SPS业务时,UE在SPS周期点使用SPS预先配置的资源发送RTP包,而对于RTCP包,现有的SPS技术并未配置发送RTCP包所需的资源,使得该些语音包不能得到及时调度,越攒越多,导致时延增加,并发生丢包现象,进而会影响用户体验。
然而,基于本发明实施例提供的补偿调度方法,在UE进行VoIP业务的场景中,上述提及的UE还需发送的业务数据包可以为RTCP包。具体地,UE在上行SPS周期点使用基站预先分配的资源、通过PUSCH向基站发送BSR,所述BSR反映了包括所述RTCP包的大小等信息;基站接收所述BSR后,若根据所述BSR确定预设条件满足时,则基站进行一次动态调度;具体地,基站根据所述BSR确定需要的补偿调度资源,然后向所述UE发送包括补偿调度资源的动态资源分配消息;所述UE使用所述补偿调度资源传输所述RTCP包等数据;如此,能实现将RTCP包及时发送,极大地降低了调度时延及丢包率,保证了业务服务质量,进而可改善用户体验。
在上述实施例基础上,所述预设条件可以包括:所述BSR属于语音数据所在的逻辑信道组(LCG,Logical Channel Group)、且所述BSR大于预设的阈值。
或者,所述预设条件可以包括:所述SPS为单周期调度模式、及所述BSR属于语音数据所在的LCG、且所述BSR大于预设的阈值。
或者,所述预设条件可以包括:所述SPS为双周期调度模式、且所述SPS周期点为所述SPS的短周期点、及所述BSR属于语音数据所在的LCG、且所述BSR大于预设的阈值。
可选的,所述预设条件还可以包括:健壮性报头压缩协议(ROHC,
Robust Header Compression)功能处于激活状态,UE使用ROHC对所述业务数据包进行报头压缩处理。这里,在针对语音业务的资源调度中,ROHC功能是默认打开的,但是ROHC功能不能保证每一包语音数据的包头长度一样。
在LTE时分双工(TDD,Time Division Duplexing)系统下,因为TDD系统的特殊性,上行SPS技术一般会默认打开双周期功能,旨在解决上行SPS数据重传的问题;LTE TDD上行SPS双周期是指UE不是按照固定的一个相同的周期进行SPS周期发数据,而是采用固定的两个不同的周期发数,举例来说,在TDD子帧配比2中,基站激活上行SPS功能、激活双周期调度功能,假设SPS双周期调度的两个周期分别为25ms和15ms,则UE会稳定的按照25ms,15ms,25ms,15ms…这样的交替SPS周期点上传数据,显然,这里,SPS的调度周期不是规则的每间隔20ms调度一次;然而,语音业务数据包的生成周期固定为20ms,这就会造成对语音包的调度不及时,造成频繁地触发补偿调度,使得在SPS周期点上出现大量调度填充(padding),但在非SPS周期点上又存在大量补偿调度的情况;如此,会造成调度不及时,并造成调度资源浪费。针对该技术问题,本发明实施例提供的补偿调度方法提供了如下技术方案:
基站在接收到UE在SPS周期点发送的BSR后,判断是否满足预设条件,即:当前SPS调度为双周期调度、且所述SPS周期点为所述SPS的短周期点、及所述BSR属于语音数据所在的LCG、且所述BSR大于预设的阈值、已激活ROHC功能;若满足该预设条件,则触发补偿调度:基站根据所述BSR确定需要的补偿调度资源,然后向所述UE发送包括补偿调度资源的动态资源分配消息;所述UE使用所述补偿调度资源传输所述BSR对应的业务数据包;本发明实施例提供的补偿调度方法,在上行SPS双周期调度的场景中,基站在SPS长周期点不进行调度补偿,而只在满足预设
条件的SPS短周期点进行调度补偿,避免了频繁地触发补偿调度,提高了补偿调度的准确性,减少了SPS周期点上的调度填充;如此,能实现将业务数据包及时发送,提高了调度资源的利用率。
图2为本发明实施例提供的补偿调度装置的结构图,所述补偿调度装置可以设置于网络接入设备,也可以单独配置;如图2所示,所述装置包括:
接收模块201,配置为接收UE在SPS周期点发送的BSR;
发送模块202,配置为根据所述BSR确定预设条件满足时,向所述UE发送包括补偿调度资源的动态资源分配消息,所述动态资源分配消息用于使所述UE使用所述补偿调度资源传输所述BSR对应的业务数据包。
本发明实施例提供的补偿调度装置,在半静态调度的基础上,当根据UE在SPS周期点发送的BSR确定预设条件满足时,向UE发送包括补偿调度资源的动态资源分配消息,以使UE使用所述补偿调度资源传输所述BSR对应的业务数据包,实现将业务数据包及时发送;如此,能极大地降低了调度时延及丢包率,保证了业务服务质量,进而可改善用户体验。
在上述实施例的基础上,所述预设条件包括:所述BSR属于语音数据所在的LCG、且所述BSR大于预设的阈值。
作为一种实施方式,所述预设条件还包括:所述SPS为单周期调度模式。
或者,所述预设条件还包括:所述SPS为双周期调度模式、且所述SPS周期点为所述SPS的短周期点。
在上述实施例的基础上,所述预设条件还包括:ROHC功能处于激活状态。
在实际应用中,所述接收模块201、发送模块202,均可由位于补偿调度装置的中央处理器(CPU,Central Processing Unit)、微处理器(MPU,
Micro Processor Unit)、数字信号处理器(DSP,Digital Signal Processor)、或现场可编程门阵列(FPGA,Field Programmable Gate Array)等实现。
本发明实施例还记载了一种计算机存储介质,所述计算机存储介质中存储有计算机可执行指令,所述计算机可执行指令用于执行前述各个实施例所述的补偿调度方法。

本发明实施例中,当根据UE在SPS周期点发送的BSR确定预设条件满足时,向UE发送包括补偿调度资源的动态资源分配消息,以使UE使用所述补偿调度资源传输所述BSR对应的业务数据包,从而将业务数据包及时发送;如此,能极大地降低了调度时延及丢包率,保证了业务服务质量,进而可改善用户体验。
Claims (11)
