具体实施方式
如图1所示的是微波无线传输网络的架构示意图，其中，近端机01通过微波链路无线接入各远端机02，以实现在无法架设或租用到有线网络的应用环境中，不同用户间的微波通信。近端机01和远端机02均可以是但不限于点对多点微波数字交换机。针对传统的无线网络存在着业务数据传输处理效率不高的问题，本申请提供的数据传输处理方法可以应用于如图1所示的应用环境中。在近端机01(或远端机02)中，近端机01获取业务数据后，进而根据业务数据的中各业务流的优先级信息，对各业务流进行二次流分类，并分别确定各类业务流的空口优先级；空口优先级用于指示相应业务流在空口队列调度时的处理顺序。
请参阅图2，在一个实施例中，提供了一种数据传输处理方法，以应用于图1所示的应用环境为例，包括如下步骤S12至S16：
S12，获取业务数据。
可以理解，业务数据为经过流量监控后的数据，可以包含一个或者多个归属不同用户的业务流(也称为数据流)。流量监控为本领域中传统的流量监测技术，用于对流量分类后的业务数据进行速率限制与优先级标记。具体的，以近端机01为例，在近端机01从以太网接收到下行的业务数据后，业务数据会先后经过流量分类和流量监控处理。因此，在近端机01内，可以从流量监控模块直接接收输出的业务数据，也可以通过其他中间处理模块来间接接收流量监控模块输出的业务数据，实现前述业务数据的获取。
S14，根据业务数据中各业务流的优先级信息，对各业务流进行二次流分类，并分别确定各类业务流的空口优先级；空口优先级用于指示相应业务流在空口队列调度时的处理优先级顺序。
可以理解，业务流的优先级信息为业务数据中，包含的各业务流所分别对应的优先 级标识信息，例如但不限于VLAN优先级、CE-VLAN信息、S-VLAN-MPLS-EXP信息、IPV4信息和IPV6信息等信息中的任意一种，或者两种及以上组合。业务流的优先级信息可以但不限于通过以太网传输的业务数据中，各业务流从信源地(如不同的用户所使用的远端机02)发出时携带相应的标识字段的方式，或者通过从以太网接收到业务流后，查询事先为各信源地的各业务流建立的优先级信息对应关系列表获知。
空口优先级是指业务数据在空口队列调度，以分配相应的空口资源的过程中，确定不同业务流的队列调度先后顺序所依据的调度优先级。在实际应用中，不同用户租用的宽带资源不同，因此，为不同用户定义的业务保障的优先级也就不同，且为同一用户的不同业务定义的优先级也不同。在用户开通微波通信服务时，为用户定义的优先级可以通过但不限于二层或三层的头部信息标识的优先级来体现。在微波无线传输网络中，不同的远端机02分别部署至各用户所在一侧，提供各用户的接入。不同远端机02在空口资源分配过程中，可按照确定的空口优先级顺序，高效处理不同远端机02的业务流。
具体的，在获取业务数据后，也即通过对应各远端机02的各虚拟端口R1～Rn从以太网侧，接收到各虚拟端口R1～Rn对应的各业务流(也称以太网以业务流)。根据业务数据中各业务流的优先级信息，将各虚拟端口R1～Rn对应的各业务流重新分类，分成不同以太网优先级类别下的业务流，进而为各类业务流确定对应的空口优先级，也即确定各类以太网业务流在后续进行空口队列调度处理过程中的调度优先级顺序。例如业务数据中包含的各以太网业务流，将优先级信息标示的优先级最高的所有业务流分为第一类，确定该类业务流的空口优先级为最高优先级；将优先级信息标示优先级第二高(次高)的所有业务流分为的第二类，确定该类业务流的空口优先级为第二高优先级，对于其他优先级的业务流同理分类和确定空口优先级。在实际应用中，不同用户的业务保障优先级不同，因此按照业务数据的优先级信息进行二次流分类后，确定各类业务流的空口优先级，即可在后续空口队列调度过程中，按照确定的空口优先级来调度相应的业务流，可高效保障不同用户的业务流的精细化微波传输处理。
上述数据传输处理方法，通过在业务数据传输处理过程中，增加二次流分类处理，确定各类优先级的业务流在空口队列调度时的空口优先级，从而提高空口调度的处理精度和效率。如此，在不影响QoS保障的情况下，实现了数据基于微波的无线传输同时，对不同用户的业务数据流可以进行更加精细的处理，可满足高优先级用户的业务保障要求；有效提高空口宽带的利用效率，达到大幅提高无线网络中业务数据传输处理效率的目的。
请参阅图3，在一个实施例中，关于上述的步骤S14，具体可以包括如下处理步骤S142和S144。
S142，分别按照各业务流对应的协议层优先级，将各业务流分为若干类；
S144，根据预设的优先级对应关系，分别确定各类业务流的空口优先级。
其中，协议层优先级是指二层与三层协议的头部信息所标识的优先级，可以由业务流携带的相应字段直接确定，例如与VLAN相应的三层IP包携带的IP优先级或者DSCP(Differentiated Services Code Point，区分服务代码点)优先级、IPV4信息和IPV6信息等携带的IP优先级或者DSCP优先级等。预设的优先级对应关系是指根据不同用户对应的业务流的优先级类型，事先设定的优先级类型与空口优先级对应关系。预设的优先级对应关系可以但不限于通过标识或者列表的方式保存在近端机01或远端机02中，只要能够确保不同用户的业务数据的优先保障传输即可。例如就微波无线传输网络中的所有用户，预先为各用户按照协议层优先级分类，并为各类型设定对应的空口优先级；当业务流归入相应的优先级类别(也即标识)后，直接按照对应关系来直接确定该业务流的空口优先级。又例如，当业务流归入相应的优先级类别后，直接查询预先存储的优先级类型与空口优先级之间对应关系的列表，确定该业务流当前所属优先级类别对应的空口优先级，从而确定该业务流的空口优先级。
具体的，在二次流分类时，分别按照各业务流对应的协议层优先级进行业务流重新分类；分类后，分别为各类业务流确定相应的空口优先级。例如将三层协议中的DSCP 值等于10的业务流分为一类，按照预设的优先级对应关系，确定该类业务流的空口优先级为最高优先级，如此，在空口队列调度过程中，将优先调度该类业务数据所在的队列。同理，对于其他优先级分类下的业务流，则分别按照预设的优先级对应关系，对应确定为其他的空口优先级，以便在空口队列调度过程中，即可按照实际确定的空口优先级高低来进行调度。
通过上述的处理步骤S142和S144，可以根据实际应用中不同用户的业务传输需求，灵活配置预设的优先级对应关系，以便在二次流分类后，对应确定不同用户的业务流的空口优先级，从而更好地提高空口调度的处理精度和效率，保障用户业务数据传输处理的效率。
请参阅图4，在一个实施例中，关于上述的步骤S14之后，还可以包括如下处理步骤S16：
S16，对确定空口优先级后的各类业务流进行宽带节省处理，得到处理后的各类业务流；处理后的各类业务流用于进行加密处理。
可以理解，宽带节省处理是指通过对业务流进行数据压缩、去重复以及其他减少业务流的流量大小手段，使得业务流占用带宽缩小的处理，只要能够确保宽带节省后，对端(如业务流需要发送到的目的远端机02)接收到的业务流中用户所需要的数据完整有效即可。相应的，在对端，可以配置与宽带节省处理过程相反的恢复处理，即可在实际应用中通过对接收到的业务流进行恢复，得到完整的业务流对应的数据。
具体的，在完成业务数据的空口优先级的确定后，即可对业务数据进行宽带节省处理，以压缩业务数据占用的带宽资源。处理后的业务数据即可送入到常规的密文处理模块进行加密处理，以进行后续的传输处理过程，直至无线发送给对端。如此，可以在不影响QoS(Quality of Service，服务质量)保障的情况下，实现业务数据基于微波的无线传输同时，节省空口带宽，达到在有限的空中带宽上尽可能传输更多的业务数据的目的。
在一个实施例中，关于上述步骤S16中，对确定空口优先级后的各类业务流进行宽带节省处理的过程，具体可以包括如下处理步骤：
对归属各远端机的各业务流进行协议头部信息压缩处理与去重复处理，得到宽带节省处理后的各业务流。
可以理解，协议头部信息也即是指二层协议与三层协议的头部信息。具体的，可以通过业务数据携带的二层或三层的头部信息识别出，该业务数据来自或者需发往的远端机02，因此，对于确定了远端机02归属的业务流，可以通过压缩该业务流的协议头部信息，以及去重复等处理，实现宽带节省的同时，不影响业务流中有用数据(即协议固定的信息以外，用户所需传输的目标数据)。
例如，将业务流中携带的多字节的MAC地址信息，压缩成较少字节的MAC地址信息，对于其他类似的协议层信息可同理进行压缩处理。对于协议固定的信息进行去除或者去除重复的部分等。相应的，在对端，只需按照发送端采用的宽带节省处理方式进行逆向恢复处理，即可在对端上得到原完整的业务流。通过上述的处理步骤，对协议头部信息进行压缩与去重复处理，可以有效节省空口有限的带宽，进一步提高业务数据传输处理效率，使空口宽带利用率最大化。
请参阅图5，在一个实施例中，空口优先级包括业务优先级和远端机优先级。关于上述步骤S14之后，还可以包括如下处理步骤S18：
S18，在进行空口队列调度时，若业务优先级最高的各业务流所需的总带宽大于空口带宽，则根据各业务流的远端机优先级，对各业务流进行空口队列调度。
可以理解，在上述各实施例中，空口队列调度可以采用传统的队列调度算法来实现。在本实施例中，则可以根据前述确定的空口优先级来进行队列调度。业务优先级为不同类型的业务流经过二次流分类后，从业务类型(例如语音业务、视频业务或者其他的业务类型)层面上确定的优先级，不同用户之间的业务优先级可以相同，也可以不同。远端机优先级也称RT(Remote Terminal，远端)优先级，是指不同类型的业务流经过二 次流分类后，从归属的远端机02这一层面上确定的优先级。不同远端机02对应着不同的用户，因此，为不同用户的定义的优先级可直接体现在远端机02的优先级上。空口带宽也即是指当前对各业务流进行空口队列调度的通信设备所拥有的空口可用带宽资源。
具体的，在进行空口队列调度时，优先调度的是业务优先级最高的各业务流，以优先保障高优先级业务流的可靠传输。当业务优先级最高的各业务流所需的总带宽大于空口带宽，则说明空口带宽不足，该次调度的各业务流无法一次性完成发送，需要将各业务流拆分后分批发送。此时，可以进一步根据各业务流的远端机优先级来进行数据拆分，分批调度。
通过上述的步骤S18，可以在有限的空口带宽资源情况下，根据业务优先级和远端机优先级的组合优先级特征，来对各业务流进行空口调度，能够更高效地保障不同用户的业务流的可靠传输。
在一个实施例中，关于上述的步骤S18中，根据各业务流的远端机优先级，对各业务流进行空口队列调度的过程，具体可以包括如下处理步骤：
按照各业务流的远端机优先级从高到低的顺序，获取总带宽等于空口带宽的若干个业务流，并进行空口队列调。
可以理解，在本实施例中，在需要进一步考虑业务数据中，各业务流的远端机优先级来进行分批调度处理时，可以按照各业务流的远端机优先级从高到低的顺序，从各业务流中每次取一定带宽大小(如空口带宽大小)的业务流进行空口调度。例如，空口带宽为2M，业务优先级最高的各业务流的大小为3M，超过了空口带宽而无法一次性调度。因此，需要从该类业务流中，取远端机优先级最高的业务流，若远端机优先级最高的业务流所需的带宽不足2M，则还可以取远端机优先级次高的业务流，依此顺序，直至所取的业务流的总带宽达到2M。然后对获取的各业务流进行空口队列调度。完成调度后，继续取该类业务流中未调度的其他业务流进行调度。
通过上述的处理步骤，可以在业务优先级最高的各业务流的带宽超过空口带宽时，进一步按照远端机优先级从高到低的顺序，优先调度远端机优先级高的业务流，以优先保障高优先级的用户的业务可靠传输。
请参阅图6，在一个实施例中，关于上述数据传输处理方法，还可以包括如下处理步骤S20：
S20，若业务优先级最高的各业务流所需的总带宽小于空口带宽，则在各业务流占用空口带宽后的剩余带宽内，对业务优先级次高的各业务流进行空口队列调度。
具体的，业务优先级最高的各业务流所需的总带宽小于空口带宽，则说明当前调度时间内，还有空口带宽空余。在本实施例中，则可以直接在剩余带宽内，对业务优先级次高的各业务流进行空口队列调度，而无需考虑各业务流的远端机优先级。例如，空口带宽有5M，业务优先级最高的各业务流所需的总带宽为3M，因此，还可以同时对2M业务优先级次高的业务流进行空口队列调度。
通过上述的步骤S20，可以在优先保障业务优先级最高的各业务流的可靠传输同时，利用剩余空口带宽，保障较低业务优先级的其他业务流的可靠传输，以充分利用空口带宽，从而进一步提高业务数据的传输处理效率。
在一个实施例中，关于上述的步骤S20中，在各业务流占用空口带宽后的剩余带宽内，对业务优先级次高的各业务流进行空口队列调度的过程，具体可以包括如下处理步骤：
若业务优先级次高的各业务流所需的总带宽大于剩余带宽，则在业务优先级次高的各业务流中，按照各业务流的远端机优先级从高到低的顺序，获取总带宽等于剩余带宽的若干个业务流，并进行空口队列调度。
具体的，在利用剩余带宽对业务优先级次高的各业务流进行空口调度时，也可能存在业务优先级次高的各业务流所需带宽不足的情况。此时，则可以进一步考虑业务优先级次高的各业务流中，各业务流的远端机优先级来进行分批调度处理。在业务优先级次 高的各业务流中，按照业务流的远端机优先级从高到低的顺序，从各业务流中每次取一定带宽大小(如剩余带宽大小)的业务流进行空口调度。例如，剩余带宽为2M，业务优先级次高的各业务流的大小为4M，超过了剩余带宽而无法一次性调度。因此，需要从该类业务流中，取远端机优先级最高的业务流，若该业务流所需的带宽不足2M，则还可以取远端机优先级次高的业务流，依此顺序，直至所取的业务流的总带宽达到2M。然后对获取的各业务流在剩余带宽内进行空口队列调度。
通过上述的处理步骤，在有剩余带宽时，于业务优先级次高的各业务流中进一步按照远端机优先级从高到低的顺序，优先调度远端机优先级高的业务流，以优先保障业务优先级次高的各业务流中，较高优先级的用户的业务可靠传输，进一步提高空口带宽的利用率。
请参阅图7，在一个实施例中，关于上述步骤S14之后，还可以包括如下处理步骤S22：
S22，在拥塞避免处理时，若空口质量低于预设质量限值，则优先丢弃空口优先级低的业务流。
可以理解，在上述实施例中，拥塞避免处理可以采用传统的拥塞避免处理，例如尾丢弃或优先级丢弃等。在本实施例中，则可以根据空口质量情况，来对不同的业务数据进行丢弃。空口质量是指根据空口的传输信号的强弱和时延大小等，确定的信号传输的好坏程度。在物理层中，近端机01与远端机02之间会交互一些固定的消息，例如近端机01以一定的周期向远端机02广播系统消息或其他通知消息，如远端机02没有响应或者是没有在规定时间内响应。近端机01即可获知当前的空口质量。预设质量限值是指在通信设备投入应用前，根据数据传输速率的应用指标，预先设置的质量限制值，例如但不限于空口传输速率限制值或信号强度限制值等。
具体的，由于空口带宽有限，当业务流的传输所需的带宽超过空口带宽时，业务流将会发生传输拥堵，如同道路上车辆过密导致发生交通堵塞。这时，便会自动触发拥塞 避免机制，对业务流进行限速传输。在当前任一远端机02所在空口的空口质量低于预设质量限值时，说明业务数据传输的可靠性变差，相应的远端机02将难以接收到完整且有效性高的业务数据。
此时，可以优先丢弃优先级低的业务数据，例如先丢弃业务优先级最低的业务流，其中，若业务优先级最低的业务流有多个，则可以优先丢弃远端机优先级低的业务流。若空口质量仍不佳，则进一步丢弃业务优先级次低的业务数据，其中，若业务优先级次低的业务流有多个，则可以优先丢弃远端机优先级低的业务流。如此，直至空口质量恢复至预设质量限值以上，以确保高优先级业务流的可靠传输。通过上述的步骤S22，可以实时根据空口质量情况，来进行拥塞避免处理，从而进一步提高业务数据传输处理效率。
在一个实施例中，如图7所示，关于上述步骤S14之前，还可以包括如下处理步骤S13：
S13，若在拥塞避免处理时空口断开，则直接丢弃空口对应类型的业务流。
可以理解，在近端机01上，空口断开是指某个远端机02所连的空口发生连接断开，这将使得该远端机02无法接收到业务数据。空口对应类型的业务流是指在当前断开的空口上，于发生断开前传输的某一类型的业务流，该业务流的类型对应于从该空口发往的远端机02，例如远端机02的视频数据或者语音数据，又或者是某一优先级类型的业务流。
具体的，当远端机02所连空口断开，在空口所属的近端机01上，直接将送往该远端机02的业务流的类型反馈给近端机01中的数据交换模块，以通知数据交换模块停止传输该类型的业务流，而直接将该类型的业务流丢弃。如此，通过上述的处理步骤S13，可以直接避免该类型业务流的分类、宽带节省与加解密等处理的开销，从而进一步地提升业务数据传输处理效率。
在一个实施例中，下面以近端机01中的数据下行传输过程为例，如图8所示的是 业务数据在近端机01中传输处理至微波无线发送的处理过程示意图，可包括如下处理步骤：
接收以太网中的业务数据后，进行一级流分类(也即传统的流量分类处理)；根据一级流分类中识别出的业务流的特征和业务数据的优先级，对业务数据对应的业务流重新标识优先级与策略限速等，完成流量监控与标记(如红色数据丢弃、重新识别与策略限速等)；在数据交换模块中，按照传统的数据交换技术识别出业务数据所需发往的远端机02；对识别出所需发往的远端机02的业务数据进行二次流分类，确定业务数据的空口优先级；对识别出所需发往的远端机02的业务数据进行宽带节省处理；对宽带节省处理后的业务数据进行加密处理，例如采用传统的AES(Advanced Encryption Standard，高级加密标准)128加密算法进行处理；拥塞避免处理与空口队列调度，根据空口调度的资源情况，将调度后的业务流重组成适合空口传输的数据帧；将数据帧发送给无线物理层进行传输。
需要说明的是，如图8中所示，R1至Rn分别表示对应各远端机02的虚拟端口(用于区分出以太网数据是转发给哪个远端机02的)。RT11至RT14分别表示第一台远端机02的4个空口队列的示意，RTn1至RTn4分别表示第n台远端机02的4个空口队列的示意，n为正整数。
在一个实施例中，仍以近端机01为例，如图9所示的是业务数据在近端机01中微波无线接收后传输处理的上行过程示意图，可包括如下处理步骤：
无线接收后，将空口数据帧拆分成有线数据帧；拥塞避免处理与空口队列调度；解密处理与宽带节省处理(对上行数据流进行恢复处理)；在数据交换模块中，按照传统的数据交换技术识别出业务数据所来自的远端机02；进行一级流分类(也即传统的流量分类处理)；根据一级流分类中识别出的业务流的特征和业务数据的优先级，对业务数据对应的业务流重新标识优先级与策略限速等，完成流量监控与标记(如红色数据丢弃、重新识别与策略限速等)；将业务数据发送以太网。需要说明的是，对于远端机02 而言，关于业务数据的下行与上行传输处理过程，远端机02中无数据交换模块，因此没有数据交换处理环节，其他处理步骤与近端机01中的相同，此处不再就远端机02再展开重复赘述。
应该理解的是，虽然图2至图7的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2至图7中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。

上述数据传输处理装置100，通过各模块的协作，通过在业务数据传输处理过程中，增加二次流分类处理，确定各类优先级的业务流在空口队列调度时的空口优先级，从而提高空口调度的处理精度和效率。如此，在不影响QoS保障的情况下，实现了数据基于微波的无线传输同时，对不同用户的业务数据流可以进行更加精细的处理，可满足高优先级用户的业务保障要求；有效提高空口宽带的利用效率，达到大幅提高无线网络中业务数据传输处理效率的目的。

在一个实施例中，上述队列调度模块还用于在业务优先级最高的各业务流所需的总带宽小于空口带宽时，在各业务流占用空口带宽后的剩余带宽内，对业务优先级次高的各业务流进行空口队列调度。充分利用空口带宽，从而进一步提高业务数据的传输处理效率。
