通信网络中的任务处理方法和通信装置
相关申请的交叉引用
本公开要求于2017年5月31日递交的中国专利申请第201710400153.9号的优先权，在此全文引用上述中国专利申请公开的内容以作为本公开的一部分。
技术领域
本申请涉及通信领域，特别涉及一种通信网络中的任务处理方法和通信装置。
背景技术
在通信网络中，用户设备(User Equipment，UE)在想要完成用户请求的某项任务时，待演进型基站(evolved Node B，eNB)向其分配无线资源后，UE可以(例如，通过UE上安装的应用程序)经由eNB向业务处理节点(如因特网中的服务器)发送任务处理请求，业务处理节点在接收到任务处理请求后，会对任务处理请求对应的任务进行处理。待业务处理节点处理完任务后会向UE返回任务的处理结果。
在上述过程中，UE和eNB之间的交互仅会考虑接入层信息(例如，UE和eNB之间的信道质量)。举例而言，某项应用任务的执行需要UE向服务器传输100比特的数据，如果UE和eNB之间的信道质量不佳，一次只能保证约30比特业务数据的传递，则UE一次只会传输30比特的数据，并将剩下的数据分多次经由eNB向服务器传输。
然而，在一些情况下，例如在无线资源有限和/或服务器超负荷运行的情况下，采用上述处理方式可能会出现服务器向UE反馈的结果出现延迟的现象，造成一方面服务器过载，另一方面UE富余的处理能力没有得到充分利用，从而无法减少无线传输资源的消耗，不利于资源利用率的提高。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1是本申请实施例提供的一种通信网络的示意图。参照图1，本申请实施例提供的通信网络可包括UE 101、eNB102、核心网110和因特网120。其中，UE 101和eNB102可无线通信。因特网120中可包括一或多个业务服务器103。一或多个业务服务器103可以为用于执行各种特定业务的服务器，例如图像识别服务器、文字翻译服务器、视频处理服务器等等。在本申请实施例中，接入网设备(如eNB102)或核心网设备(图1中未示出)上可部署MEC单元。本申请实施例中的接入网设备除了可包括eNB，还可包括其他独立的设备(例如专门部署于接入网中的服务器)，此独立的设备处于接入网中且可部署MEC单元。MEC单元承载了业务服务器的部分或全部功能。例如，MEC单元可承载图像识别功能、文字翻译功能等等。
下面以任务处理请求对应的任务中包括多个子任务为例来进行说明。在本申请实施例中，在核心网设备上部署MEC单元的情况下，UE 101发出任务处理请求后，可经由eNB102发往核心网设备，核心网设备可处理任务处理请求对应的任务中的至少一个子任务，并将其他的子任务交由UE 101和/或因特网120中的业务服务器103来执行。可选地，在接入网设备(例如eNB102)上部署MEC单元的情况下，接入网设备(例如eNB102)在接收到来自UE 101的任务处理请求后，可处理任务处理请求对应的任务中的至少一个子任务，并将 其他的子任务交由UE 101和/或因特网120中的业务服务器103来执行。
当然，在本申请实施例中，通信网络中的各个装置也可以均不部署MEC单元，在此情况下，可选地，eNB102在接收到来自UE 101的任务处理请求后，可将任务处理请求对应的任务中的至少一个子任务交由UE 101和/或因特网120中的业务服务器103来执行；或者，eNB102在接收到来自UE 101的任务处理请求后，可将此任务处理请求转发给核心网设备，进而核心网设备可将任务处理请求对应的任务中的至少一个子任务交由UE 101和/或因特网120中的业务服务器103来执行。
以上是以任务处理请求对应的任务中包括多个子任务为例来进行说明。当任务处理请求对应的任务为单个任务(即，不包含多个子任务)时，eNB102或核心网设备可将此任务交由UE 101和/或因特网120中的业务服务器103来执行。
需了解的是，本申请实施例提供的通信网络中的任务处理方法可由通信网络中的各种装置执行，例如由接入网设备(例如eNB)执行，核心网设备执行等。核心网设备可包括但不限于，MME、PGW和SGW等。下面结合图2对本申请实施例提供的通信网络中的任务处理方法进行进一步说明。
图2是本申请实施例提供的一种通信网络中的任务处理方法的流程图。参照图2，本申请实施例提供的通信网络中的任务处理方法可包括：
步骤21，接收来自UE的任务处理请求。
本申请实施例中的“任务处理请求”用以请求对某项任务进行处理，这项任务可以是用户指定的任务，也可以是UE内部执行的工作任务。UE发出的任务处理请求举例而言可以为，请求识别摄像头拍摄的图片中的文字、请求将摄像头拍摄的图片中的文字由英文翻译成中文、请求虚拟现实游戏中某一个三维场景的数据等等。
步骤12，获取针对任务处理请求的应用层信息、UE针对任务处理请求的能力信息，以及接入层信息。
在本申请中，应用层信息为与任务处理相关的信息，且可包括：图像识别能力信息、语音识别能力信息、音频/视频处理能力信息、定位能力信息和图形产生能力信息等等。
当图2所示方法由接入网设备执行时，以eNB执行为例，eNB可从UE获取针对任务处理请求的应用层信息，以及在eNB上未部署有MEC单元的情况下，eNB可从接入网中部署有MEC的独立设备(在接入网中存在此独立设备的情况下)、核心网设备(例如核心网设备上部署有MEC单元的情况下)或因特网服务器(例如核心网设备上未部署有MEC单元的情况下)获取针对任务处理请求的应用层信息。当然，在eNB上部署有MEC单元的情况下，eNB可只从UE获取针对任务处理请求的应用层信息。而当图2所示方法由接入网中的独立设备执行时，此独立设备可从UE获取针对任务处理请求的应用层信息，并在此独立设备上未部署有MEC的情况下，可从部署有MEC的eNB、部署有MEC的核心网设备或因特网服务器获取针对任务处理请求的应用层信息。当然，在此独立设备上部署有MEC的情况下，此独立设备可只从UE获取针对任务处理请求的应用层信息。
而当图2所示方法由部署有MEC单元的核心网设备执行时，核心网设备可只需从UE获取针对任务处理请求的应用层信息，而未部署有MEC单元的核心网设备不仅需从UE获取针对任务处理请求的应用层信息，还会从因特网服务器或部署有MEC单元的核心网设备 (例如，eNB或独立设备)获取针对任务处理请求的应用层信息。
本申请实施例中的“UE针对任务处理请求的能力信息”可包括以下至少一种：计算能力信息、应用处理能力信息(例如，图像识别能力、图形计算能力等)和存储能力信息。其中，视任务类型而定，UE的能力信息的具体内容可以不同。即，不同的任务可对应不同的能力信息。例如，在任务为“识别摄像头拍摄的图片中的文字”时，能力信息可以为图像识别能力信息，即是否有能力识别图片中的文字。
UE在向eNB发送任务处理请求时，可以同时将自身针对任务处理请求的能力信息向eNB上报，例如任务处理请求中携带自身的能力信息。当然，在本申请实施例中，UE的任务处理请求和UE针对任务的能力信息也可以以先后顺序分别上报。举例而言，在任务处理请求为“识别摄像头拍摄的图片中的文字”时，若UE有识别图片中的文字的图像处理能力，则UE可在任务处理请求中携带能力信息“能够识别图片中的文字”，或者先后发送任务处理请求和能力信息。
接入层信息可包括以下至少一种：信道质量信息、信道强度信息、小区的负载信息、网络状态信息和频率资源信息。在图2所示方法由eNB执行时，eNB可直接获取到接入层信息。而当图2所示方法由核心网设备执行时，核心网设备会从UE对应的eNB获取接入层信息。
步骤23，根据能力信息、应用层信息和接入层信息，确定执行任务的装置。
在任务为不包含多个子任务的单个任务时，可根据能力信息、应用层信息和接入层信息，直接确定执行任务的装置。执行任务的装置可以为UE、接入网设备、核心网设备或因特网服务器。
在任务包括至少两个子任务时，对于每个子任务，根据能力信息、应用层信息和接入层信息，可通过下面的任一种方式来确定执行子任务的装置。需了解的是，下面列出的几种方式只是示例，在本申请保护范围内的其他方式也可用来确定执行子任务的装置。
方式一：在接入层信息指示所述UE适于执行所述子任务时，基于能力信息确定UE是否有能力处理子任务；在UE有能力处理子任务时，确定UE为执行子任务的装置；在UE没有能力处理子任务时，根据应用层信息确定接入网设备、核心网设备或因特网服务器为执行子任务的装置；
在接入层信息指示所述UE不适于执行所述子任务时，根据应用层信息确定接入网设备、核心网设备或因特网服务器为执行子任务的装置。
当然，在确定执行任务的装置的过程中，也可以采用与上面所举的方式不同的方式(例如，下面的方式二或方式三)来确定执行任务的装置。
方式二：优先考虑应用层信息，在应用层信息指示核心网设备有能力处理子任务且未过载时，确定核心网设备为执行子任务的装置；
在应用层信息指示接入网设备、核心网设备或因特网服务器有能力处理子任务且过载时，根据能力信息确定UE是否有能力处理子任务；在UE没有能力处理子任务时，确定接入网设备、核心网设备或因特网服务器为执行子任务的装置；在UE有能力处理子任务且UE适于执行子任务时，确定UE为执行子任务的装置；在UE有能力处理子任务且UE不适于执行子任务时，确定UE、接入网设备、核心网设备或因特网服务器为执行子任务的装 置。
方式三：可选地，在能力信息指示UE没有能力处理子任务时，根据应用层信息确定接入网设备、核心网设备或因特网服务器为执行子任务的装置；
在能力信息指示UE有能力处理子任务时，确定接入层信息指示UE是否适于执行所述子任务；在接入层信息指示UE适于执行子任务时，确定UE为执行子任务的装置；在接入层信息指示UE不适于执行子任务时，确定UE、接入网设备、核心网设备或因特网服务器为执行子任务的装置。
需要指出的是，本申请中提到的“接入层信息指示UE适于执行子任务”是指，当前的接入层信息指示适合在UE侧执行子任务，而不是将子任务交由网络侧装置处理(例如，网络侧装置繁忙)。例如，在传输子任务的数据需要占用大量上行空口资源而上行空口资源不足(例如，小于阈值)的情况，可为本申请中“接入层信息指示UE适于执行子任务”的情况。又例如，在传输子任务的数据需要占用少量下行空口资源而下行空口资源充足(例如，大于阈值)的情况，可为本申请中“接入层信息指示UE适于执行子任务”的情况。
本申请中提到的“接入层信息指示UE不适于执行子任务”是指，当前的接入层信息指示不适合在UE侧执行子任务，而是将子任务交由网络侧装置处理(例如，网络侧装置空闲)。例如，在传输子任务的数据需要占用少量上行空口资源而上行空口资源充足(例如，大于阈值)的情况，可为本申请中“接入层信息指示UE不适于执行子任务”的情况。又例如，在传输子任务的数据需要占用大量下行空口资源而下行空口资源不足(例如，小于阈值)的情况，可为本申请中“接入层信息指示UE不适于执行子任务”的情况。
这里只是以举例的方式来说明确定执行子任务的装置的各种方式，由于无法穷举，在本申请中，只要是根据能力信息、应用层信息和接入层信息来确定执行子任务的装置的方式均在本申请保护的范围内。
同时需了解的是，在任务为不包含多个子任务的单个任务时，也可以通过上面的任一种方式来确定执行任务的装置。
步骤24，向执行任务的装置发送处理指示信息，处理指示信息用于指示对任务处理请求对应的任务进行处理。其中，执行任务的装置为UE、核心网设备、因特网服务器中的至少一者。
在本申请实施例中，当UE请求处理的任务为不包含多个子任务的单个任务(例如，需要翻译用户手动输入的一个单词)时，执行任务的装置可以为UE、接入网设备、核心网设备或因特网服务器。此时，执行任务的装置在根据接收到处理指示信息处理完这个任务后，可让UE在显示界面上呈现处理结果。以任务为需要将用户手动输入的一个单词翻译成中文为例，在执行任务的装置为文字翻译服务器时，文字翻译服务器在获取指示信息并后会将单词翻译成中文，并将结果经由eNB传输给UE，进而让UE在显示界面上显示单词的翻译结果。
以上是以不包含多个子任务的情形为例来进行说明，但是在很多情况下，任务往往是复杂的任务，即任务包括多个子任务。在UE发出的任务处理请求对应的任务包括至少两个子任务时，对于每个子任务，可根据能力信息、应用层信息和接入层信息，确定执行子任务的装置，并向执行子任务的装置分别发送处理指示信息。举例而言，假定有三个子任务， 执行各个子任务的装置分别为UE、核心网设备或因特网服务器，则在图2所示方法由eNB执行时，eNB可向UE发送第一处理指示信息，向核心网设备发送第二处理指示信息，向因特网服务器发送第三处理指示信息。而在图2所示方法由核心网设备执行时，核心网设备可向UE发送第一处理指示信息，向因特网服务器发送第二处理指示信息。
本申请实施例提供的通信网络中的任务处理方法，综合考虑能力信息、应用层信息和接入层信息来进行任务调度，并发出处理指示信息，指示执行任务的装置对任务进行处理，如此能够提高资源的利用率。
下面结合图3和图4以任务包括第一子任务和第二子任务为例对本申请实施例提供的通信网络中的任务处理方法进行进一步说明。其中，图3所示实施例由eNB执行，图4所示实施例由核心网设备执行。需了解的是，本文中只是以任务包括第一子任务和第二子任务为例进行说明，需了解的是，在任务包括至少三个子任务的情况可类似进行处理，本文不再进行赘述。
图3是本申请实施例提供的任务处理方法的示意图。参照图3，本申请实施例提供的任务处理方法由eNB执行，并可包括如下步骤：
步骤31，UE向eNB上报任务处理请求、UE针对任务处理请求的能力信息以及针对任务处理请求的应用层信息。
在本申请中，任务处理请求、UE针对任务处理请求的能力信息以及针对任务处理请求的应用层信息可分别上报或一起上报，本申请对此并不限定。
步骤32、eNB获取针对任务处理请求的应用层信息。在eNB上部署有MEC单元时，eNB可直接获取针对任务处理请求的应用层信息。可选地，在eNB上未部署有MEC单元时，eNB可从接入网中部署有MEC的独立设备、部署有MEC的核心网设备或因特网服务器获取针对任务处理请求的应用层信息。
步骤33，eNB例如通过接收UE反馈的测量报告获取接入层信息。
在本申请中，UE可根据接收到的来自eNB的测量配置执行测量，并生成测量报告，并由UE将测量报告上报给eNB。测量报告中包括接收信号强度和接收信号质量，还可包括测量标识、服务小区的测量结果和邻小区的测量结果等。
步骤34，eNB根据能力信息、应用层信息和接入层信息，确定UE为执行第一子任务的装置，部署有MEC单元的核心网设备为执行第二子任务的装置，生成第一处理指示信息和第二处理指示信息，并向UE发送第一处理指示信息，向部署有MEC单元的核心网设备发送第二处理指示信息。
当然，在本步骤中，若核心网设备不具备执行第二子任务的能力，则eNB可用接入网中部署有MEC的独立设备(若存在的话)或因特网服务器来代替核心网设备作为执行第二子任务的装置，并向因特网服务器发出第二处理指示信息。
以上只是确定执行子任务的装置的一种示例。对于每个子任务，根据能力信息、应用层信息和接入层信息，确定执行子任务的装置的方式在本申请中并不具体限定。各种具体确定方式的举例可参照上文。
步骤35，eNB向UE分配空口资源。
步骤36，UE和核心网设备就任务处理进行应用数据交互。
UE在接收到第一处理指示信息之后，可按照第一处理指示信息进行任务处理。核心网设备在接收到第二处理指示信息之后，可按照第二处理指示信息进行任务处理。
需了解的是，本实施例中的任务包括第一子任务和第二子任务且子任务之间的执行可存在依赖关系，例如，第二子任务的执行依赖于第一子任务的处理结果。此时，UE按照第一处理指示信息对第一子任务处理完毕后，可将第一子任务的处理结果反馈给核心网设备。核心网设备可按照第二处理指示信息的指示，并基于第一子任务的处理结果来处理第二子任务，在第二子任务处理完毕后，将处理结果反馈给UE。在本申请实施例中，UE可根据核心网设备反馈的第二子任务的处理结果(其可以为最终的处理结果)在显示界面上显示任务的处理结果。
同理，在任务包括N(N＞2，且N为整数)个子任务时，执行第K(K为整数，K＜N)个任务的装置在将第K个子任务处理完毕后，可向执行第K+1个子任务的装置反馈第K个任务的执行结果，以便于执行第K+1个子任务的装置基于第K个子任务的执行结果来处理第K+1个子任务。
本申请实施例提供的通信网络中的任务处理方法，eNB综合考虑UE针对任务处理请求的能力信息、应用层信息和接入层信息来确定执行子任务的装置，并发出处理指示信息，在此过程中充分利用了UE和/或核心网设备的处理能力，如此提高了资源的利用率，减少无线传输资源的消耗，有利于网络容量的提升。
下面举例进行进一步说明。需了解的是，下面各个示例中确定执行子任务的装置的方法仅为举例，目的是为了方便本领域技术人员更好地理解本申请，而并不意为限制。
示例1
本示例中的任务处理请求例如为“将摄像头拍摄的图片中的英文文字翻译成中文”，此时，UE上报的应用层信息可以为：摄像头拍摄的图片信息，例如图片大小、清晰度等。任务处理请求对应的任务包括两个子任务，即第一子任务：识别摄像头拍摄的图片中的英文文字；第二子任务：将图片中的英文文字翻译成中文。UE的能力信息为：能够将英文文字翻译成中文，但不能够识别图片中的英文文字。
初始时，UE向eNB发送任务处理请求、应用层信息(例如，摄像头拍摄的图片的大小信息)以及UE的能力信息。同时，eNB会获取接入层信息以及从核心网设备或因特网服务器获取针对任务处理请求的应用层信息。
eNB在获取接入层信息、UE的能力信息和应用层信息后，若发现UE没有能力处理第一子任务，但接入层信息指示UE适于执行第二子任务，则确定部署有MEC单元的核心网设备(这里只是举例，当然也可以是因特网服务器)为执行第一子任务的装置，UE为执行第二子任务的装置，并向核心网设备发送第一处理指示信息，向UE发送第二处理指示信息。第一处理指示信息指示核心网设备识别摄像头拍摄的图片中的英文文字，第二处理指示信息指示UE将英文文字翻译成中文。这里需了解，若UE的能力信息为能够识别图片中的英文文字但不能将英文文字翻译成中文，则在接入层信息指示UE适于执行第一子任务时，可将第一子任务交给UE来执行，将第二子任务交由核心网设备来处理。
核心网设备在接收到第一指示信息之后，会将摄像头拍摄的图片中的英文文字识别出 来，并经由eNB发送给UE。
进而，UE可根据接收到的英文文字执行第二子任务，即，将接收到的英文文字翻译成中文文字。最终可在UE的显示界面上显示任务“将摄像头拍摄的图片中的英文文字翻译成中文”的结果。
这里需了解的是，在UE和核心网设备交互之前，eNB会给UE分配无线资源，使得UE可根据分配的无线资源经由eNB和核心网设备进行应用数据的交互。
本申请实施例提供的通信网络中的任务处理方法，eNB综合考虑能力信息、应用层信息和接入层信息来确定执行子任务的装置，并发出处理指示信息，在此过程中充分利用了UE和/或核心网设备的处理能力，如此提高了资源的利用率，减少无线传输资源的消耗，有利于网络容量的提升。

本示例中的任务处理请求例如为“申请渲染虚拟现实游戏中某一个三维场景”，UE上报的应用层信息可以为此三维场景的信息。任务包括两个子任务，即第一子任务：获取虚拟现实游戏中这个三维场景的数据；第二子任务：根据获取的数据，渲染出三维场景。UE的能力信息为：具有3D图像渲染能力。
初始时，UE向eNB发送任务处理请求、应用层信息(例如，需要渲染的三维场景的信息)以及UE的能力信息。同时，eNB会获取接入层信息以及从核心网设备或因特网服务器获取针对任务处理请求的应用层信息。
eNB在获取接入层信息、UE的能力信息和应用层信息后，若接入层信息指示UE适于执行第二子任务且应用层信息指示核心网设备有能力处理第一子任务，则确定部署有MEC单元的核心网设备为执行第一子任务的装置，UE为执行第二子任务的装置。eNB会向核心网设备发送第一处理指示信息，向UE发送第二处理指示信息。第一处理指示信息指示核心网设备获取虚拟现实游戏中这个三维场景的数据；第二处理指示信息指示UE渲染出三维场景。如此，可减少空口资源的消耗。
核心网设备在接收到第一处理指示信息之后，会获取虚拟现实游戏中这个三维场景的数据，并将获取的数据向UE传输。UE在接收到第二处理指示之后，根据来自核心网设备的数据渲染出三维场景。进而，UE可在显示界面上显示渲染出的三维场景。

图4是本申请实施例提供的任务处理方法的示意图。参照图4，本申请实施例提供的任务处理方法由核心网设备执行，核心网设备上可部署有MEC单元。本申请实施例提供的任务处理方法可包括如下步骤：
步骤41，UE经由eNB向核心网设备上报任务处理请求、UE针对任务处理请求的能力信息以及针对任务处理请求的应用层信息。
步骤42、eNB获取接入层信息。例如，通过接收UE发送的测量报告获取接入层信息。
步骤43，核心网设备从eNB获取接入层信息。
步骤44，核心网设备根据UE针对任务处理请求的能力信息、应用层信息和接入层信息，确定UE为执行第一子任务的装置，核心网设备自身为执行第二子任务的装置，生成第一处理指示信息，并向UE发送第一处理指示信息。
当然，在本步骤中，若核心网设备自身也无法执行第二子任务，则可确定因特网服务器为执行第二子任务的装置，并生成第二处理指示信息，向因特网服务器发送第二处理指示信息。进而，因特网服务器可根据第二处理指示信息对第二子任务进行处理。
其中，对于每个子任务，核心网设备根据UE针对任务处理请求的能力信息、应用层信息和接入层信息，确定执行子任务的装置的方式在本申请中并不具体限定。各种具体确定方式的举例可参照上文。
步骤45，核心网设备向eNB发送资源分配请求，资源分配请求用于指示eNB向UE分配的空口资源。空口资源包括时域和/或频域资源。
步骤46，eNB按照资源分配请求向UE分配空口资源。
步骤47，UE和核心网设备就任务处理进行应用数据交互。
UE在接收到第一处理指示信息之后，可UE按照第一指示信息处理第一子任务。核心网设备可根据UE处理第一子任务的结果来处理第二子任务。
需了解的是，本实施例中的任务包括第一子任务和第二子任务且子任务之间的执行可存在依赖关系，例如，第二子任务的执行依赖于第一子任务的处理结果。此时，UE按照第一指示信息对第一子任务处理完毕后，可将第一子任务的处理结果反馈给核心网设备。核心网设备可基于第一子任务的处理结果来处理第二子任务，在第二子任务处理完毕后，将处理结果反馈给UE。UE可根据核心网设备反馈的第二子任务的处理结果(其可以为最终的处理结果)在显示界面上显示任务的处理结果。
同理，在任务包括N(N＞2，且N为整数)个子任务时，执行第K(K为整数，K＜N)个任务的装置在将第K个子任务处理完毕后，可向执行第K+1个子任务的装置反馈第K个任务的执行结果，以便于执行第K+1个子任务的装置基于第K个子任务的执行结果来处理第K+1个子任务。
本申请实施例提供的通信网络中的任务处理方法，核心网设备综合考虑UE针对任务处理请求的能力信息、应用层信息和接入层信息来确定执行子任务的装置，并发出处理指示信息，在此过程中充分利用了UE和/或核心网设备的处理能力，如此提高了资源的利用率，减少无线传输资源的消耗，有利于网络容量的提升。
示例3
本示例中的任务处理请求例如为“将摄像头拍摄的图片中的英文文字翻译成中文”，此时，任UE上报的应用层信息可以为：摄像头拍摄的图片信息，例如图片大小、清晰度等。任务处理请求对应的任务包括两个子任务，即第一子任务：识别摄像头拍摄的图片中的英文文字；第二子任务：将图片中的英文文字翻译成中文。UE的能力信息为：能够将英文文字翻译成中文，但不能够识别图片中的英文文字。
初始时，UE经由eNB向核心网设备发送任务处理请求、应用层信息(例如，摄像头拍摄的图片的大小信息)以及UE的能力信息。同时，核心网设备会从eNB获取接入层信息， 接入层信息包括例如信道质量和网络状态信息等。
核心网设备在获取接入层信息、UE的能力信息后，若发现UE没有能力处理第一子任务，且接入层信息指示UE适于执行第二子任务，则确定自身为执行第一子任务的装置，UE为执行第二任务的装置，并向UE发送处理指示信息。处理指示信息指示UE将英文文字翻译成中文。这里需了解，若UE的能力信息为能够识别图片中的英文文字但不能将英文文字翻译成中文，则在接入层信息指示UE适于执行第一子任务时，也可将第一子任务交给UE来执行，将第二子任务都交由核心网设备来处理。
核心网设备将摄像头拍摄的图片中的英文文字识别出来，并经由eNB发送给UE。
进而，UE可根据接收到的英文文字执行第二子任务，即，将接收到的英文文字翻译成中文文字。最终可在UE的显示界面上显示任务“将摄像头拍摄的图片中的英文文字翻译成中文”的结果。
这里需了解的是，在UE和核心网设备交互之前，eNB会给UE分配无线资源，使得UE可根据分配的无线资源经由eNB和核心网设备进行应用数据的交互。
本申请实施例提供的通信网络中的任务处理方法，核心网设备综合考虑UE针对任务处理请求的能力信息、应用层信息和接入层信息来确定执行子任务的装置，并发出处理指示信息，在此过程中充分利用了UE和/或核心网设备的处理能力，如此提高了资源的利用率，减少无线传输资源的消耗，有利于网络容量的提升。

核心网设备在获取接入层信息、UE的能力信息后，在能力信息指示UE没有能力处理第一子任务时，则核心网设备确定部署有MEC单元的核心网设备为执行第一子任务的装置；同时，在能力信息指示UE有能力处理第二子任务且接入层信息指示UE适于执行第二子任务时，核心网设备确定UE为执行第二子任务的装置，并向UE发送处理指示信息。指示信息用于指示UE执行第二子任务。
核心网设备会获取虚拟现实游戏中这个三维场景的数据，并将获取的数据经由eNB发往UE，UE会根据接收到的三维场景的数据渲染出三维场景，并将渲染出的三维场景。进而，UE可在显示界面上显示渲染出的三维场景。

图5是本申请实施例提供的通信装置的结构示意图。任务处理装置可以为eNB或核心网设备。参照图5，通信装置500包括处理器(processor)510、通信接口(Communications Interface)520、存储器(memory)530和总线540。处理器510、通信接口520、存储器530通过总线540完成相互间的通信。通信接口520用于与网元通信。处理器510，用于执行程序532。程序532可以包括程序代码，程序代码包括计算机操作指令。处理器510可能是一个中央处理器CPU，或者是特定集成电路ASIC(Application Specific Integrated Circuit)，或者是被配置成实施本申请实施例的一个或多个集成电路。存储器530，用于存放程序532。存储器530可能包含高速RAM存储器，也可能还包括非易失性存储器(non-volatile memory)，例如至少一个磁盘存储器。当计算机指令被处理器加载并执行时，执行本文的任一种通信网络中的任务处理方法。
需要说明的是：本申请实施例提供的通信网络中的通信装置与通信网络中的任务处理方法实施例属于同一构思，相关内容可参见方法实施例，这里不再赘述。
图6是本申请实施例提供的一种媒体数据传输方法的流程图。本申请实施例提供的媒体数据传输方法可包括：
步骤61，eNB在转发媒体数据的过程中，检测接入层信息是否发生变化。接入层信息包括无线信道质量、网络的状态、小区状态信息等。
在本步骤之前，UE和MEC网元之间会经由eNB进行媒体数据传输。具体地，MEC网元可向UE发送媒体文件信息，UE可根据接收到的媒体文件信息经由eNB向MEC网元发送媒体数据请求，MEC网元在接收到媒体数据请求后，会经由eNB向UE发送媒体数据响应。
在本申请实施例中，MEC网元是指部署有MEC单元的装置。MEC网元可以是eNB，也可以是核心网设备等。
eNB在对UE和MEC网元之间的媒体数据进行转发的过程中，会检测接入层信息是否发生变化。
步骤62，eNB在检测到接入层信息发生变化时，向UE发送调整的媒体参数。媒体参数可包括媒体数据调整时间间隔、传输可用带宽信息、媒体分片大小建议等。
在本申请实施例中，eNB可通过介质访问控制控制元素(Medium Access Control Control Element,MAC CE)或无线资源控制(Radio Resource Control，RRC)信令将需要调整的媒体参数发送给UE。
步骤63，UE在接收到来自eNB的调整的媒体参数后，根据调整的媒体参数向MEC网元发送媒体数据请求，使得MEC网元根据接收的媒体数据请求来向UE发送媒体数据响应。
本步骤中，UE在接收到来自eNB的调整的媒体参数后，会将调整的媒体参数经由内部的接入层传递到内部的应用层。此传递过程的具体实现过程本申请并不限定。如此，UE的应用层即可根据获取到的调整的媒体参数向MEC网元发送媒体数据请求。
本申请实施例中，在媒体数据传输的过程中，考虑了接入层信息，在检测到接入层信息发生变化时，可动态调整媒体参数，如此可优化资源利用率。
在本申请实施例中，可选地，UE可主动向eNB上报媒体信息。进而，eNB在检测到 接入层信息发生变化时，可根据UE上报的媒体信息来调整媒体参数。如此，可以保证调整后的媒体参数综合考虑了UE之前的媒体数据传输情况(应用层信息)和接入层信息，不仅可优化资源利用率，而且能够保证较好的用户体验。
在本申请实施例中，UE向eNB上报的媒体信息可包括：媒体文件分片大小、媒体调整申请间隔、媒体文件数据率可选范围等。
下面以媒体参数为媒体数据调整时间间隔为例来对本申请实施例进行进一步说明。
在本申请实施例中，eNB可通过MAC CE或RRC信令将媒体参数发送给UE。
以MAC CE方式来调整媒体数据调整时间间隔为例，MAC CE的内容可如图7所示。参照图7，图7示出了一个八位组。R表示保留比特，D表示上下行指示，D＝0表示下行，D＝1表示上行，推荐调整间隔(Recommended Tunning interval)表示建议的调整间隔，可以是建议值的绝对值，也可以是量化的映射表格，还可以是相对调整值，相对调整档次。R和D可占用一个比特，推荐调整间隔可占用4个比特。
其中，调整间隔值的方式可如图8或图9所示。参见图8，推荐调整间隔的不同比特取值可对应于不同的调整时间间隔。例如，推荐调整间隔取值为0000表示调整时间间隔为1毫秒，推荐调整间隔取值为1001表示调整时间间隔为0.2毫秒等。参照图9，推荐调整间隔的不同比特取值可对应于不同的调整时间间隔档位。例如推荐调整间隔取值为0000表示调整时间间隔提高一档，推荐调整间隔取值为1001表示调整时间间隔下降二档等。在本申请中，每一档的时间可预先设定。
当然，在本申请实施例中，eNB还可以通过RRC信令来将媒体参数发送给UE。
RRC信令的具体内容可如下：
Figure PCTCN2018089149-appb-000001
此RRC信令可对应于图8所示推荐调整间隔取具体调整时间间隔值的情形。
RRC信令的具体内容还可如下：
Figure PCTCN2018089149-appb-000002
Figure PCTCN2018089149-appb-000003
此RRC信令可对应于图9所示推荐调整间隔取调整时间间隔档位的情形。
UE在接收到eNB发出的MAC CE或RRC信令后，即可获取媒体数据调整时间间隔，并根据获取的媒体数据调整时间间隔向MEC网元发送媒体数据请求，MEC网元在接收到来自UE的此媒体数据请求后，会根据接收的此媒体数据请求来向UE发送媒体数据响应。
本申请实施例提供的媒体数据传输方法，综合考虑应用层信息和接入层信息调整媒体数据调整时间间隔(提供最优时间粒度)，可优化资源利用率，提供良好的用户体验。
相应地，本申请实施例还可提供一种媒体数据传输系统，包括UE和eNB。其中，eNB用于执行上文提到的步骤61和步骤62，UE用于执行上文提到的步骤63。步骤的具体内容可参照上文描述。
除非另作定义，此处使用的技术术语或者科学术语应当为本申请所属领域内具有一般技能的人士所理解的通常意义。本申请专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上所述仅为本申请的可选实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
