具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1A是根据一示例性实施例示出的一种蜂窝网络中实现边缘计算的方法的流程图，图1B是根据一示例性实施例示出的一种蜂窝网络中实现边缘计算的方法的场景图；该蜂窝网络中实现边缘计算的方法可以应用在用户设备上，如图1A所示，该蜂窝网络中实现边缘计算的方法包括以下步骤101-102：
在步骤101中，接收具有边缘计算能力的基站发送的携带边缘计算指示信息的广播信令。
在一实施例中，具有边缘计算能力的基站可以理解为基站具有计算、存储、应用核心能力，例如，可在基站中部署“视频缓存应用”，利用该边缘计算应用(视频缓存应用)，可将某些视频的内容缓存在基站上，当用户请求下载的视频内容属于该应用缓存的视频内容时，基站可以直接将该应用存储的视频内容发给用户设备。在又一实施例中，具有边缘计算能力的基站还可以理解为基站可以直接访问具有边缘计算能力的服务器，该服务器位于基站侧，不位于核心网中，基站可以基于该具有边缘计算能力的服务器为用户设备提供边缘智能服务，如提供高清视频、虚拟现实、增强现实 及在线游戏等服务。
在一实施例中，边缘计算指示信息可以只指示基站具有边缘计算能力，如向用户设备指示基站支持边缘计算，但是不公开具体支持的服务项目。
在一实施例中，边缘计算指示信息还可以直接指示基站所支持的具体的边缘计算服务项目，如支持“视频缓存应用”、“增强现实应用”、“虚拟现实应用”等等。
在步骤102中，在需要获取业务数据时，基于广播信令发送获取业务数据的业务请求消息。
在一实施例中，处于连接态或者非激活态的用户设备需要获取业务数据时，可以先确定要获取的业务数据是否与基站支持的边缘计算能力匹配，如果匹配，则可直接向基站发送业务请求消息；如果不匹配，则可向核心网发送业务请求消息。
在一实施例中，对于广播信令中携带的边缘计算指示信息只指示基站具有边缘计算能力时，用户设备获取基站提供的边缘计算服务的流程可参见图2A和图2B所示实施例，广播信令中携带的边缘计算指示信息指示基站所支持的具体的边缘计算服务项目时，用户设备获取基站提供的边缘计算服务的流程可参见图3A和图3B所示实施例，这里先不详述。
在一实施例中，处于空闲态的用户设备在需要获取业务数据时，可以先建立与所驻留的基站之间的RRC连接，以切换到连接态，然后即可确定要获取的业务数据是否与基站支持的边缘计算能力匹配，如果匹配，则可直接向基站发送业务请求消息；如果不匹配，则可向核心网发送业务请求消息。
在一示例性场景中，如图1B所示，在图1B所示的场景中，包括基站10，用户设备20，基站10可以为5G基站，如新的无线(New Radio，简称为NR)基站和eLTE基站、用户设备可以为智能手机、平板电脑等，其中，基站10可广播携带边缘计算指示信息的广播信令，用户设备20监听到广播信令后，处于空闲态的用户设备20可基于广播信令选择合适的基站进行驻留，或者处于连接态或者非激活态的用户设备20可以在有匹配基站的边缘计算能力的业务数据需要请求时，直接向基站10发送业务请求消息，而不是向核心网发送，由此可实现业务数据传输经过的路径大大减少，从而缩短用户获取业务数据的时间。
本实施例通过上述步骤101-步骤102，可以实现基站高效地传输自己的边缘计算能力，并且为用户设备提供边缘计算服务。
在一实施例中，边缘计算指示信息指示基站所支持的边缘计算服务项目。
在一实施例中，基于广播信令发送获取业务数据的业务请求消息，包括：
若业务数据与边缘计算服务项目匹配，则向基站发送业务请求消息；
若业务数据与边缘计算服务项目不匹配，则向核心网发送业务请求消息。
在一实施例中，蜂窝网络中实现边缘计算的方法还可以进一步包括：
在选择基站进行驻留时，基于用户设备的历史行为数据确定用户设备待传输业务数据的数据类型；
基于待传输业务数据的数据类型，优先驻留在支持与数据类型匹配的边缘计算服务项目的基站。
在一实施例中，边缘计算指示信息指示基站具有边缘计算能力。
在一实施例中，基于广播信令发送获取业务数据的业务请求消息，包括：
向基站发送获取基站所支持的边缘计算服务项目的请求消息；
接收基站基于请求消息返回的响应消息；
从响应消息中解析得到基站所支持的边缘计算服务项目；
若业务数据与边缘计算服务项目匹配，则向基站发送业务请求消息；
若业务数据与边缘计算服务项目不匹配，则向核心网发送业务请求消息。
在一实施例中，蜂窝网络中实现边缘计算的方法还可以进一步包括：
在选择基站进行驻留时，优先驻留在支持边缘计算能力的基站。
具体如何蜂窝网络中实现边缘计算的，请参考后续实施例。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2A是根据一示例性实施例示出的又一种蜂窝网络中实现边缘计算的方法的流程图一，图2B是根据一示例性实施例示出的又一种蜂窝网络中实现边缘计算的方法的流程图二；；本实施例利用本公开实施例提供的上述方法，以边缘计算指示信息只指示基站具有边缘计算能力时，用户设备基于基站的广播信令获取边缘计算智能服务为例进行示例性说明，如图2A所示，为处于空闲态的用户设备基于广播信令进行基站驻留的过程，包括如下步骤：
在步骤201中，用户设备接收具有边缘计算能力的基站发送的携带边缘计算指示信息的广播信令。
在步骤202中，用户设备在选择基站进行驻留时，优先驻留在支持边缘计算能力的基站。
在一实施例中，处于空闲态的用户设备在选择基站进行驻留时，可以基于每一个基站的广播信令，在覆盖当前位置的信号质量相差不大的不同的基站中，优先选择驻留在支持边缘计算能力的基站，其中，广播信令中的边缘计算指示信息用于指示基站是否具有 边缘计算能力。
在一实施例中，如果用户设备接收不同基站的信号质量相差较大，则仍可选择优先驻留在信号质量好的基站中。
在一实施例中，处于空闲态的UE在接收到业务请求时，可首先建立与所驻留的基站之间的RRC连接，切换到连接态，然后再基于广播信令执行业务请求的过程，基于广播信令执行业务请求的过程参见图2B所示实施例。
如图2B所示，为处于连接态或者非激活态的用户设备基于广播信令进行业务请求的过程，包括如下步骤：
在步骤211中，用户设备接收具有边缘计算能力的基站发送的携带边缘计算指示信息的广播信令。
在步骤212中，用户设备在需要获取业务数据时，向基站发送获取基站所支持的边缘计算服务项目的请求消息。
在一实施例中，如果广播信令中所包含的边缘计算指示信息只指示基站支持边缘计算能力，用户设备可在需要获取业务数据时，向基站请求其所支持的边缘计算服务项目。
在步骤213中，用户设备接收基站基于请求消息返回的响应消息。
在步骤214中，用户设备从响应消息中解析得到基站所支持的边缘计算服务项目，并且判断业务数据是否与边缘计算服务项目匹配，如果匹配，则执行步骤215，如果不匹配，则执行步骤217。
在步骤215中，若业务数据与边缘计算服务项目匹配，则用户设备向基站发送业务请求消息。
在一实施例中，如果业务数据与边缘计算服务项目匹配，则可说明基站应该足可以为用户设备发送相关的业务数据，因此不需要再向核心网请求。例如，当用户请求业务数据属于该应用缓存的视频内容时，而基站所支持的边缘计算服务项目包括视频缓存，因此基站可以直接向基站发送业务请求消息，基站可将该应用存储的视频内容下发给用户，由此视频文件传输经过的路径大大减少，从而减少了用户下载视频的延时。
在步骤216中，用户设备接收基站基于业务请求消息返回的业务数据。
在步骤217中，若业务数据与边缘计算服务项目不匹配，则用户设备向核心网发送业务请求消息。
在步骤218中，用户设备接收核心网设备基于业务请求消息通过基站返回的业 务数据。
在一实施例中，核心网设备接收到业务请求消息之后，需要向应用服务器发送获取业务数据的请求消息，然后再将获取的业务数据通过基站转发给用户设备。
本实施例中，在广播信令只指示基站具有边缘计算能力，而不指示具体的边缘计算服务器项目时，处于空闲态的用户设备可优先驻留在具有边缘计算能力的基站，而处于连接态的用户设备可向基站请求其所支持的边缘计算服务项目，进而基于基站返回的边缘计算服务项目发送获取业务数据的业务请求消息，由于广播信令中只指示是否支持边缘计算能力，因此广播信令所携带的边缘计算指示信息比较小，可以尽量减小广播信令所占用的资源。
图3A是根据一示例性实施例示出的再一种蜂窝网络中实现边缘计算的方法的流程图一，图3B据一示例性实施例示出的再一种蜂窝网络中实现边缘计算的方法的流程图二；本实施例利用本公开实施例提供的上述方法，以边缘计算指示信息指示基站的边缘计算服务项目时，用户设备基于基站的广播信令获取边缘计算智能服务为例进行示例性说明，如图3A所示，为处于空闲态的用户设备基于广播信令进行基站驻留的过程，包括如下步骤：
在步骤301中，用户设备接收具有边缘计算能力的基站发送的携带边缘计算指示信息的广播信令。
在步骤302中，用户设备从广播信令中解析边缘计算指示信息，执行步骤304。
在一实施例中，本实施例中的边缘计算指示信息还可以直接指示基站所支持的具体的边缘计算服务项目，如支持“视频缓存应用”、“增强现实应用”、“虚拟现实应用”等等。
在步骤303中，用户设备在选择基站进行驻留时，基于用户设备的历史行为数据确定用户设备待传输业务数据的数据类型。
在一实施例中，历史行为数据可以理解为用户访问网络的使用数据，例如，用户一般在8点到9点玩在线游戏，而在中午12点到一点半看视频，则用户设备在8点到9点钟选择基站进行驻留时，可以确定用户设备待传输业务数据的数据类型为在线游戏类数据。
在步骤304中，基于待传输业务数据的数据类型，用户设备优先驻留在支持与数据类型匹配的边缘计算服务项目的基站。
在一实施例中，基于待传输业务数据的数据类型，在选择基站进行驻留时，如果当前有信号质量相差不大的基站时，可以优先选择驻留在与待传输业务数据的数据 类型匹配的边缘计算服务项目的基站。例如，待传输业务数据的数据类型为增强现实显示应用，而当前有信号质量相差很小或者相同的两个基站，基站1支持增强现实的边缘计算服务项目，而基站2支持视频存储的边缘计算服务项目，则用户设备可优先主流在基站1中。
在一实施例中，处于空闲态的UE在接收到业务请求时，可首先建立与所驻留的基站之间的RRC连接，切换到连接态，然后再基于广播信令执行业务请求的过程，基于广播信令执行业务请求的过程参见图2B所示实施例。
如图3B所示，为处于连接态或者非激活态的用户设备基于广播信令进行业务请求的过程，包括如下步骤：

在步骤312中，用户设备从广播信令中解析边缘计算指示信息。
在步骤313中，用户设备在需要获取业务数据时，确定边缘计算指示信息所指示的边缘计算服务项目与要获取的业务数据是否匹配，如果匹配，则执行步骤314，如果不匹配，则执行步骤315。
在步骤314中，若业务数据与边缘计算服务项目匹配，则用户设备向基站发送业务请求消息，流程结束。

在步骤402中，基站发送广播信令。
在一实施例中，基站在发送广播信令之后，如果接收到用户设备发送的业务请求消息，则可直接从本地获取获取业务请求消息所请求的业务数据并发送至给用户设备，或者从具有边缘计算能力的服务器业务请求消息所请求的业务数据并发送至给用户设备。
在一示例性场景中，如图1B所示，在图1B所示的场景中，包括基站10，用户设备20，基站10可广播携带边缘计算指示信息的广播信令，以使得用户设备20监听到广播信令后，处于空闲态的用户设备20可基于广播信令选择合适的基站进行驻留，或者处于连接态或者非激活态的用户设备20可以在有匹配基站的边缘计算能力的业务数据需要请求时，直接向基站10发送业务请求消息，基站10接收到业务请求消息之后即可将对应的业务数据返回给用户设备20。
本实施例通过上述步骤401-步骤402，可以实现基站高效地传输自己的边缘计算能力，进而为用户设备提供边缘计算服务。
