Description

一种资源调度方法及装置
本申请基于申请号为CN201610228432.7、申请日为2016年4月13日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域的资源分配技术，尤其涉及一种资源调度方。
背景技术
卫星通信就是利用卫星作为中继而进行的通信，由于卫星通信具有通信范围大，不易受陆地灾害的影响可靠性高，开通迅速以及设置灵活等优点，近年来发展十分迅速。
现有的DVB-RCS标准协议中，卫星通讯系统采用时分复用(Time Division Multiplexed，TDM)传输，每一帧都只能对应一种帧结构以及一种调制编码模式。其中，帧结构包括长帧和短帧两种类型，相同带宽配置下长帧帧长是短帧帧长的4倍，相同调制编码模式(Modulation Codes Schema，MCS)下长帧比短帧的频谱效率更高。从以上协议特点可知，在无线条件环境多变的应用场景下，长帧比短帧频谱利用率更高，而长帧结构的调度灵活性比短帧结构差。
现有技术中，每个信道使用的帧结构是预先配置好的，当信道采用长帧结构时，如果待调度的数据量较小，容易影响系统的调度灵活性；当信道采用短帧结构时，如果待调度的数据量较大，容易导致频谱利用率较低。

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。
实施例一
本发明实施例提供一种资源调度方法，应用于卫星通讯系统的地面端，如图1所示，包括：
步骤101、获取待调度数据的数据量。
示例的，当终端采用卫星通讯系统进行数据传输时，如果需要进行传输的数据量较大时，可以将需要传输的数据划分为多个数据包，按照数据包的形式依次进行传输，到达目的地后重新组合，因此所述待调度数据可以为一个数据包，该数据包的大小即为待调度数据的数据量。
步骤102、根据所述待调度数据的数据量，选择调度所述待调度数据的帧结构。
示例的，如果待调度数据的数据量较大，可以选择长帧结构作为调度所述待调度数据的帧结构，由于长帧结构比短帧结构的帧头开销小，即长帧结构的有效符号利用率较高，相同MCS的情况下长帧比短帧的频谱效率更高，因此采用长帧结构作为调度所述待调度数据的帧结构能够提高系统的带宽利用率；如果待调度数据的数据量较小，可以选择短帧结构作为调度所述待调度数据的帧结构，由于相同带宽配置下短帧帧长是长帧帧长的四分之一，因此采用短帧结构作为调度所述待调度数据的帧结构能够提高系统的调度灵活性。
步骤103、根据选择的帧结构，调度所述待调度数据。
示例的，长帧结构和短帧结构都可以支持多种MCS，例如正交相移键控(Quadrature Phase Shift Keyin，QPSK)、8移相键控(8Phase Shift Keying，8PSK)、16振幅移相键控(16Amplitude Phase Shift Keying，16APSK)或32APSK。不同的MCS以及不同码率(Code Rates，CR)结合可以得到多种不同的调制编码方式，每种调制编码方式有对应的信噪比解调门限，并支持自适应编码调制(Adaptive Coding and Modulation，ACM)、恒定编码和调制(Constant Coding and Modulation，CCM)两种调度模式，其中ACM比CCM调度模式更灵活，更适用信号环境多变的应用场景，可以有效的提高系统带宽利用率，而CCM调度模式相对比较保守，可靠性高，带宽利用率低。在确定调度所述待调度数据的帧结构之后，可以选择ACM或CCM任意一种方式调度所述待调度数据。
这样一来，由于可以根据每个待调度数据的数据量，选择调度每个待调度数据的帧结构，当待调度数据的数据量较大时，可以选择长帧结构调度所述待调度数据；当待调度数据的数据量较小时，可以选择短帧结构调度所述待调度数据，实现了帧结构的动态选择，提高了整个系统的带宽利用率和调度灵活性。
可选的，在根据所述待调度数据的数据量，选择调度所述待调度数据的帧结构时，可以首先确定所述待调度数据的数据量是否大于或等于长帧结构的数据块。若所述待调度数据的数据量大于或等于长帧结构的数据块，选择长帧结构作为调度所述待调度 数据的帧结构；若所述待调度数据的数据量小于长帧结构的数据块，选择短帧结构作为调度所述待调度数据的帧结构。
示例的，可以以长帧结构的数据块为基准进行判断，若所述待调度数据的数据量大于或等于长帧结构的数据块，说明待调度数据的数据量较大，而短帧结构中除去帧销开头之后剩余的可承载数据的容量较小，如果采用短帧结构进行调度，可能需要的短帧结构较多，导致系统的带宽利用率较低，因此可以选择长帧结构对所述待调度数据进行调度。若所述待调度数据的数据量小于长帧结构的数据块，说明待调度数据的数据量较小，而长帧结构的帧长较长，如果采用长帧结构进行调度，可能出现待调度数据的数据量小于长帧可承载数据容量的情况，此时还需要等待其他数据占用剩余的容量之后，才能进行数据传输，导致系统的调度灵活性较低，因此可以采用短帧结构作为调度所述待调度数据的帧结构。
可选的，在根据所述待调度数据的数据量，选择调度所述待调度数据的帧结构时，也可以首先确定所述待调度数据的数据量是否大于或等于短帧结构的数据块。若所述待调度数据的数据量大于或等于短帧结构的数据块，选择长帧结构作为调度所述待调度数据的帧结构；若所述待调度数据的数据量小于短帧结构的数据块，选择短帧结构作为调度所述待调度数据的帧结构。
示例的，也可以以短帧结构的数据块为基准进行判断，若所述待调度数据的数据量大于或等于短帧结构的数据块，说明待调度数据的数据量较大，而短帧结构中除去帧销开头之后剩余的可承载数据的容量较小，如果采用短帧结构进行调度，可能需要多个短帧结构，导致系统的带宽利用率较低，因此可以选择长帧结构对所述待调度数据进行调度。若所述待调度数据的数据量小于短帧结构的数据块，说明待调度数据的数据量较小，而长帧结构的帧长较长，如果采用长帧结构进行调度，可能出现待调度数据的数据量小于长帧可承载数据容量的情况，此时还需要等待其他数据占用剩余的容量之后，才能进行数据传输，导致系统的调度灵活性较低，因此可以采用短帧结构作为调度所述待调度数据的帧结构。
进一步的，在所述获取待调度数据的数据量之前，还可以根据所述待调度数据的类型，确定所述待调度数据的MCS。
示例的，所述待调度数据的类型可以分为广播数据或单播数据，所述广播数据为全网发送的数据，需要网络内每一个终端都能够接收到，因此可以选择最低阶的MCS进行发送；所述单播数据为网络单独发给某一个终端的数据。由于采用高阶的MCS 发送数据能够提高频谱利用率，因此一般情况下倾向于选在较高阶的MCS，但是越高阶的MCS对终端当前的信噪比要求越高，因此若待调度数据为单播数据时，可以首先确定接收终端当前的信噪比，然后根据信噪比选择合适的MCS，可以尽量选择较高阶的MCS，提高网络的频谱利用率。
可选的，在根据所述待调度数据的类型，确定所述待调度数据的MCS时，若所述待调度数据的类型为时延敏感广播数据类型，确定所述待调度数据的MCS为第一MCS；若所述待调度数据的类型为非时延敏感广播数据类型，确定所述待调度数据的MCS为第二MCS；若所述待调度数据的类型为单播数据类型，根据所述待调度数据的信噪比确定所述待调度数据的MCS。
示例的，为了提高调度的灵活性，可以对广播数据和单播数据再进行细化分类，分为时延敏感广播数据、非时延敏感广播数据、时延敏感单播数据、非时延敏感单播数据四种数据类型。其中，时延敏感广播数据是指对时延要求非常高的广播数据，主要包括协议信令、以及传输时延要求高的广播数据等，例如L2S和对时延要求较高的HTTP流媒体直播(HTTP Live Streaming，HLS)信令数据；所述非时延敏感广播数据是指对时延要求不高的广播数据，主要包括上层应用广播信令以及传输时延要求低的广播数据，例如，对时延要求不高的HLS信令数据；所述时延敏感单播数据是指对时延要求高的单播数据，主要包括上层应用单播信令以及语音应用相关时延要求高的数据，例如，应用语音相关数据；所述非时延敏感单播数据是指对时延要求低的单播数据，主要包括上层应用普通应用单播数据。
若待调度数据的类型为时延敏感广播数据类型，说明该待调度数据需要及时发出，并且保证网络内的每个终端都能够接收到，因此可以选择预设的第一MCS进行发送，所述第一MCS可以为较低阶的MCS；若所述待调度数据的类型为非时延敏感广播数据类型，说明该待调度数据对时延的要求不高，可以不及时发送，但是也需要保证网络内的每个终端都能够接收到，因此可以选择预设的第二MCS进行发送，所述第二MCS可以为较低阶的MCS；实际应用中，所述第一MCS与所述第二MCS可以根据具体情况进行设置，所述第一MCS与所述第二MCS可以相同，也可以不同，本发明实施例对此不做限定。若所述待调度数据的类型为单播数据，无论是否为时延敏感，均可以根据待调度数据的信噪比确定所述待调度数据的MCS。
进一步的，在所述根据所述待调度数据的类型，确定所述待调度数据的调制编码模式MCS之前，还可以首先获取多个待发送数据，确定每个待发送数据的类型，然 后根据每个所述待发送数据的类型，确定每个所述待发送数据的优先级，进而按照每个所述待发送数据的优先级，选择当前的所述待调度数据。
示例的，由于卫星通信网络内数据交互较多，同一时间可能接收到多个数据包需要进行发送，而每个数据包的类型又不同，有些是对时延要求较高的，有些是对时延要求不高的，如果按顺序进行发送，可能会耽误很多数据包的时延，所以可以按照数据的类型，排列优先级，按照优先级顺序进行发送。假设数据可以分为时延敏感广播数据、非时延敏感广播数据、时延敏感单播数据、非时延敏感单播数据四种数据类型，该四种数据类型的优先级顺序可以为时延敏感广播数据，非时延敏感广播数据，时延敏感单播数据，非时延敏感单播数据。其中，广播数据的优先级高于单播数据的优先级，时延敏感类数据的优先级高于非时延敏感类数据的优先级。然后按照优先级选择当前的待调度数据。例如，首先接收需要发送给终端的多个待发送数据，然后确定每个待发送数据的类型，进而能够根据每个待发送数据的类型确定每个待发送数据优先级，例如，如果待发送数据为时延敏感广播数据，则优先级最高；如果待发送数据为非时延敏感单播数据，则优先级最低。在确定了每个待发送数据的优先级之后，可以按照待发送数据的优先级，确定出当前的待调度数据。
本发明实施例提供一种资源调度方法，包括：获取待调度数据的数据量；根据所述待调度数据的数据量，选择调度所述待调度数据的帧结构；根据选择的帧结构，调度所述待调度数据。相较于现有技术，由于可以根据每个待调度数据的数据量，选择调度每个待调度数据的帧结构，当待调度数据的数据量较大时，可以选择长帧结构调度所述待调度数据；当待调度数据的数据量较小时，可以选择短帧结构调度所述待调度数据，实现了帧结构的动态选择，提高了整个系统的带宽利用率和调度灵活性。
实施例二
本发明实施例提供一种资源调度方法，应用于卫星通讯系统的地面端，所述地面端是卫星通讯系统与地面公众网的接口，终端也可以通过地面端出入卫星系统形成链路，所述地面端还可以包括地面卫星控制中心，及其跟踪、遥测和指令站。如图2所示，所述资源调度方法包括：
步骤201、接收多个需要发送给终端的待发送数据，执行步骤202。
实际应用中，卫星通信网络内数据交互较多，同一时间可能有多个数据包需要进行发送，因此一个时间段内可以获得多个待发送数据。
步骤202、确定每个待发送数据的类型，执行步骤203。
示例的，可以将待发送数据分为时延敏感广播数据、非时延敏感广播数据、时延敏感单播数据、非时延敏感单播数据四种数据类型。
步骤203、根据每个待发送数据的类型，确定每个待发送数据的优先级，执行步骤204。
示例的，上述四种数据类型的优先级顺序可以为时延敏感广播数据，非时延敏感广播数据，时延敏感单播数据，非时延敏感单播数据。其中，广播数据的优先级高于单播数据的优先级，时延敏感类数据的优先级高于非时延敏感类数据的优先级。然后按照优先级选择当前的待调度数据。然后可以根据待发送数据的类型，确定每个待发送数据的优先级，例如，若待发送数据为时延敏感广播数据，则优先级最高；若待发送数据为非时延敏感单播数据，则优先级最低。
步骤204、根据每个待发送数据的优先级，选择当前的待调度数据，执行步骤205。
示例的，在确定了每个待发送数据的优先级之后，可以按照优先级，选择当前需要进行调度的待调度数据。例如可以首先选择优先级较高的类型为时延敏感广播数据的待发送数据作为当前调度的待调度数据，然后选择优先级次之的类型为非时延敏感广播数据待发送数据作为下一次调度的待调度数据。具体的选择顺序可以根据实际情况进行设置，本发明实施例对此不做限定。
步骤205、根据所述待调度数据的类型，确定所述待调度数据的MCS，执行步骤206。
示例的，低阶的MCS虽然会导致频谱利用率较低，但是却能够保证网络内每一个终端都能够接收到；高阶的MCS虽然能够提高频谱利用率，但是对终端当前的信噪比要求较高，信号差的终端可能无法接收，因此实际应用中，可以根据待调度数据的类型确定所述待调度数据的MCS。若待调度数据的类型为时延敏感广播数据类型，可以选择预设的第一MCS进行发送，所述第一MCS可以为较低阶的MCS；若所述待调度数据的类型为非时延敏感广播数据类型，可以选择预设的第二MCS进行发送，所述第二MCS可以为较低阶的MCS；实际应用中，所述第一MCS与所述第二MCS可以根据具体情况进行设置，所述第一MCS与所述第二MCS可以相同，也可以不同，本发明实施例对此不做限定。若所述待调度数据的类型为单播数据，无论是否为时延敏感，均可以根据待调度数据的信噪比确定所述待调度数据的MCS。
步骤206、获取所述待调度数据的数据量，执行步骤207。
步骤207、确定所述待调度数据的数据量是否大于或等于长帧结构的数据块；当 所述待调度数据的数据量大于或等于长帧结构的数据块时，执行步骤208；当所述待调度数据的数据量小于长帧结构的数据块时，执行步骤209。
示例的，可以以长帧结构的数据块为基准进行判断，若所述待调度数据的数据量大于或等于长帧结构的数据块，说明待调度数据的数据量较大，此时可以选择长帧结构对所述待调度数据进行调度。若所述待调度数据的数据量小于长帧结构的数据块，说明待调度数据的数据量较小，此时可以采用短帧结构作为调度所述待调度数据的帧结构。
步骤208、采用长帧结构和确定的MCS调度所述待调度数据，本流程结束。
示例的，如果待调度数据为时延敏感广播数据，且数据量大于或等于长帧结构的数据块，可以选择长帧结构和第一MCS进行调度；如果待调度数据为非时延敏感广播数据，且数据量大于或等于长帧结构的数据块，可以选择长帧结构和第二MCS进行调度；如果待调度数据为单播数据，且数据量大于或等于长帧结构的数据块，可以选择长帧结构和根据信噪比确定的MCS进行调度。
步骤209、采用短帧结构和确定的MCS调度所述待调度数据。
示例的，如果待调度数据为时延敏感广播数据，且数据量小于长帧结构的数据块，可以选择短帧结构和第一MCS进行调度；如果待调度数据为非时延敏感广播数据，且数据量小于长帧结构的数据块，可以选择短帧结构和第二MCS进行调度；如果待调度数据为单播数据，且数据量小于长帧结构的数据块，可以选择短帧结构和根据信噪比确定的MCS进行调度。
本发明实施例提供一种资源调度方法，相较于现有技术，由于可以根据每个待调度数据的数据量，选择调度每个待调度数据的帧结构，当待调度数据的数据量较大时，可以选择长帧结构调度所述待调度数据；当待调度数据的数据量较小时，可以选择短帧结构调度所述待调度数据，实现了帧结构的动态选择，提高了整个系统的带宽利用率和调度灵活性。

步骤301、接收多个需要发送给终端的待发送数据，执行步骤302。
步骤302、确定每个待发送数据的类型，执行步骤303。
步骤303、根据每个待发送数据的类型，确定每个待发送数据的优先级，执行步骤304。

步骤305、根据所述待调度数据的类型，确定所述待调度数据的MCS，执行步骤306。
步骤306、获取所述待调度数据的数据量，执行步骤307。
所述步骤301至步骤306可以参考前述步骤201至步骤206，本发明实施例在此不做赘述。
步骤307、确定所述待调度数据的数据量是否大于或等于短帧结构的数据块；当所述待调度数据的数据量大于或等于长帧结构的数据块时，执行步骤308；当所述待调度数据的数据量小于长帧结构的数据块时，执行步骤309。
示例的，可以以短帧结构的数据块为基准进行判断，若所述待调度数据的数据量大于或等于短帧结构的数据块，说明待调度数据的数据量较大，此时可以选择长帧结构对所述待调度数据进行调度。若所述待调度数据的数据量小于短帧结构的数据块，说明待调度数据的数据量较小，此时可以采用短帧结构作为调度所述待调度数据的帧结构。

示例的，如果待调度数据为时延敏感广播数据，且数据量大于或等于短帧结构的数据块，可以选择长帧结构和第一MCS进行调度；如果待调度数据为非时延敏感广播数据，且数据量大于或等于短帧结构的数据块，可以选择长帧结构和第二MCS进行调度；如果待调度数据为单播数据，且数据量大于或等于短帧结构的数据块，可以选择长帧结构和根据信噪比确定的MCS进行调度。
步骤309、采用短帧结构和确定的MCS调度所述待调度数据。
示例的，如果待调度数据为时延敏感广播数据，且数据量小于短帧结构的数据块，可以选择短帧结构和第一MCS进行调度；如果待调度数据为非时延敏感广播数据，且数据量小于短帧结构的数据块，可以选择短帧结构和第二MCS进行调度；如果待调度数据为单播数据，且数据量小于短帧结构的数据块，可以选择短帧结构和根据信噪比确定的MCS进行调度。
本发明实施例提供一种资源调度方法，相较于现有技术，由于可以根据每个待调 度数据的数据量，选择调度每个待调度数据的帧结构，当待调度数据的数据量较大时，可以选择长帧结构调度所述待调度数据；当待调度数据的数据量较小时，可以选择短帧结构调度所述待调度数据，实现了帧结构的动态选择，提高了整个系统的带宽利用率和调度灵活性。
需要说明的是，本发明方法实施例提供的资源调度方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本发明的保护范围之内，因此不再赘述。
