Description

移动边缘设备、连接管理器、系统、方法、装置及介质 技术领域
本发明涉及通信领域，特别是一种移动边缘设备、连接管理器、移动边缘设备的动态无线连接管理系统、方法、装置及计算机可读存储介质。
背景技术
目前，很多不同的无线技术，如WLAN、4/5G、蓝牙、Zigbee等，被部署在许多应用中。以Wi-Fi为例，有些Wi-Fi网络可以访问互联网，有些则不能。即使可以访问互联网的Wi-Fi，通常也会被增加一些额外的限制，例如，阻止访问购物网站等。对于工业WLAN，其设计可用于专用目的，例如冗余/时间关键型应用。面对如此众多的无线网络，用户设备(UE)或其他移动边缘设备通常不知如何选择合适的网络以满足其需求。
例如，在办公室里，有人想利用手机通过Wi-Fi上网，他需要首先利用手机扫描获取周围无线网络的列表，但他并不知道哪个网络可以访问互联网。即便经过咨询后连接到对应的网络，但过了一会儿他发现网速太慢，于是他再次获得帮助选择到新的网络。但过了一会儿他想网购，发现该新的网络被设置了限制而无法访问购物网站，他又需要重新选择网络。可见，他的基本要求是访问互联网，但有时他会改变需求去购物，甚至会再次改变需求。然而，目前并没有一种简单的方法可以帮助他在不断变化的需求下切换到正确的网络。
又如，在工厂中，由于灵活生产的需要，自动导引运输车(AGV，Automated Guided Vehicle)需要连接各种网络。假设某车间部署有控制网络、固件更新网络、视频传输网络等，安装在AGV上的边缘设备可以在这些网络之间进行连接和切换。例如，在A区，AGV需要操作某些东西，此时需要连接控制网络以完成时间关键任务，于是它首先扫描并获得网络列表，但它不知道哪个网络属于控制网络。即使AGV知道网络类型，但如果存在相同类型的可用网络，AGV仍然无法进行选择，因为一个好的无线网络的选择通常需要考虑许多条件，如接收的信号强度指示(RSSI，Received Signal Strength Indicator)、吞吐量、延迟、连接性等。此外，在运行一段时间后，AGV可能改变其需求，并且需要切换到其他网络，此时它需要再次选择网络。然而，目前尚没有一种简单的方法可以帮助AGV等工业移动边缘设备在不断变化的需求下切换到正确的网络。

具体实施方式
考虑到目前UE和移动边缘设备可以获得网络列表，且可以获知自身对于不同网络的网络需求，只是不知道哪些网络是最佳网络。因此，本发明实施例中，考虑提供一种动态网络服务发现方案，以帮助UE和移动边缘设备选择最佳网络。为了描述方便，本文中，将UE也称为移动边缘设备。
移动边缘设备是指具有至少一个无线接口，且能够运行具有不同连接需求和流量需求的应用的无线移动计算设备。其中，至少一个无线接口可包括：802.11xx、4/5G、蓝牙、ZigBee等中的至少一个。此外，至少一个无线接口可以同时工作。UE支持的无线技术可包括：Wi-Fi和4/5G，定制设备可支持不同的Wi-Fi标准，如802.11ad、802.11ac/ax等。
为使本发明的目的、技术方案和优点更加清楚，以下举实施例对本发明进一步详细说明。
图1为本发明实施例中一种移动边缘设备的动态无线连接管理系统的示例性结构图。如 图1所示，该系统可包括：连接管理器110、移动边缘设备120和多个无线网络130。
其中，移动边缘设备120具有至少一个无线接口且运行有至少一个应用，用于获取自身应用的网络需求，并通过所述无线接口扫描得到附近的可用无线网络列表，将所述网络需求与所述可用无线网络列表发送给连接管理器110，并接收连接管理器110反馈的推荐无线网络列表，从所述推荐无线网络列表中为所述应用选择出最佳的无线网络进行连接。例如，可从中自主决策确定最优无线网络。
其中，每个应用通过一个无线接口访问一个无线网络，且多个应用可共享同一个无线接口。具体实现时，所述至少一个应用可设置有连接优先级，相应地，移动边缘设备120在发现一个无线接口同时对应多个应用时，可根据所连接优先级从所述推荐无线网络列表中为所述当前运行的应用选择最佳的无线网络。例如，可为最高优先级的应用选择性能最佳的无线网络。当然，若每个无线接口只有一个应用的连接，则为所述应用选择无线网络时，则无需参考各个应用的优先级。
此外，移动边缘设备120可进一步存储来自所述连接管理器的推荐无线网络列表；并监控所述无线接口连接的无线网络是否发生变化，如发生变化，则获取通过所述无线接口连接所述无线网络的应用的网络需求，并根据所述网络需求查看自身存储的推荐无线网络列表中是否存在能够满足所述网络需求的下一个无线网络，如果是，则为通过所述无线接口连接所述无线网络的应用连接所述下一个无线网络；否则，通过所述无线接口扫描得到附近的可用无线网络列表，将所述网络需求和所述可用无线网络列表提供给所述连接管理器。
进一步地，移动边缘设备120还可进一步用于定期与连接管理器110同步本地无线网络信息。具体地，可按照设定间隔获取当前运行的应用的网络需求，并通过所述无线接口扫描得到附近的可用无线网络列表，将所述网络需求和所述可用无线网络列表提供给所述连接管理器，接收所述连接管理器反馈的推荐无线网络列表，利用新接收的推荐无线网络列表更新之前存储的推荐无线网络列表，并判断所述当前运行的应用当前连接的无线网络是否位于所述推荐无线网络列表中，如果是，则保持所述连接；否则，从所述推荐无线网络列表中为所述当前运行的应用选择最佳的无线网络进行连接。
连接管理器110用于接收来自移动边缘设备120的网络需求及可用无线网络列表，并查询所述可用无线网络列表中的各个无线网络是否能够满足所述网络需求，并将满足所述网络需求的无线网络作为推荐无线网络向所述移动边缘设备反馈一推荐无线网络列表。
具体实现时，连接管理器110可有多种实现方式。例如，连接管理器110上可预先配置有各个无线网络的属性信息；其中，无线网络的属性信息可包括：服务区别号(ESSID，Extended Service Set Identifier)、网络类型(如普通网络、专用网络、公有网络、私有网络等)、MAC地址、IP地址、用户名、密码、网络协议、是否允许接入、以及适用场景等。连接管理器110在接收到来自移动边缘设备120的网络需求及可用无线网络列表后，可根据所述可用无线网络列表中的各个无线网络的属性信息，确定对应所述网络需求的侯选无线网络130，并向每个侯选无线网络130发送负载调查请求，接收来自各个侯选无线网络130的负载信息，根据所述负载信息确定满足所述网络需求的推荐无线网络，并向移动边缘设备120反馈对应的推荐无线网络列表。相应地，各个无线网络130用于在接收到来自连接管理器110的所述负载调查请求后，将包括自身容量和当前流量的负载信息反馈给连接管理器110。
此外，在其他实施方式中，连接管理器110上可进一步配置有各个无线接口可访问的无线网络信息，例如，配置有无线接口标识与可访问的无线网络之间的对应关系等。相应地，来自移动边缘设备120的可用无线网络列表中可进一步包括获取所述可用无线网络列表的各个无线接口的标识。此时，连接管理器110可根据所述可用无线网络列表从所述配置模块中查询所述可用无线网络列表中的各个无线网络的属性信息以及对应所述标识的无线接口的可访问无线网络信息，根据所述属性信息以及对应所述标识的无线接口的可访问无线网络信息确定对应所述网络需求的侯选无线网络130。
本发明实施例中，移动边缘设备120与连接管理器110之间的连接可以有多种实现方式。例如，可以基于默认协议直接连接。或者，也可以基于HTTP重定向机制由服务网络进行连接。此时，连接管理器110可在后端运行，移动边缘设备120可通过如图1中虚线部分所示的服务网络140建立与连接管理器110之间的连接。为了使移动边缘设备120对服务网络与常规的无需网络进行区分，可对服务网络进行标识。例如，假设服务网络是WLAN网络，则可将特定的SSID分配给该服务网络和/或可将信标帧中的特殊字段用于将网络标记为服务网络。此时，边缘管理设备120可用于在需要请求所述连接管理器的帮助时，向服务网络140发送所述连接请求。服务网络140可根据所述连接请求，基于捕获门户中常用的HTTP重定向机制，将移动边缘设备的连接重定向到特定的WEB地址，即连接管理器110的地址，从而建立所述移动边缘设备与所述连接管理器之间的连接。
具体实现时，连接管理器110和边缘管理设备120可分别有多种具体结构形式。
例如，图2示出了本发明一个例子中连接管理器110的结构示意图。如图2所示，该连接管理器110可包括：配置模块111、移动边缘设备连接器112、需求处理模块113、响应处理模块114和无线网络连接器115。
其中，所述配置模块111上配置有各个无线网络的属性信息。

需求处理模块113用于根据所述可用无线网络列表从配置模块111中查询所述可用无线网络列表中的各个无线网络的属性信息，根据所述属性信息确定对应所述网络需求的侯选无线网络，并针对每个侯选无线网络生成一负载调查请求，将所述负载调查请求提供给无线网络连接器115。
无线网络连接器115用于将所述负载调查请求发送给对应的候选无线网络，并接收来自所述候选无线网络的负载信息，将所述负载信息提供给响应处理模块114。
响应处理模块114用于根据所述负载信息确定满足所述网络需求的推荐无线网络，并将对应的推荐无线网络列表提供给移动边缘设备连接器112。
在一个实施方式中，配置模块111上可进一步配置有各个无线接口可访问的无线网络信息。相应地，来自移动边缘设备120的所述可用无线网络列表中可进一步包括获取所述可用无线网络列表的各个无线接口的标识。此时，需求处理模块113可根据所述可用无线网络列表从配置模块111中查询所述可用无线网络列表中的各个无线网络的属性信息以及对应所述标识的无线接口的可访问无线网络信息，根据所述属性信息以及对应所述标识的无线接口的可访问无线网络信息确定对应所述网络需求的侯选无线网络。
又如，图3示出了本发明一个例子中移动边缘设备120的结构示意图。如图3所示，该移动边缘设备120可包括：无线接口模块121、应用模块122、扫描和连接模块123和应用管理模块124。
其中，无线接口模块121包括至少一个无线接口。
