本公开的较佳实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开实施例提供的方法可以但不仅限应用于图1所示的系统中。在该系统中,路由器101用于采集并上报接入的终端设备102的信息,云服务器103用于根据路由器101上报的信息对终端102进行识别,得到其设备信息, 并通过安装有目标应用程序的终端设备104输出接入路由器101的终端设备102的设备信息。
其中,图1中的路由器101还可以替换为其他IOT(Internet of Things,物联网)设备,或者智能移动终端(如智能手机、平板电脑等)。
其中,接入的终端设备102是指接入路由器101以连接到局域网或者互联网的终端设备,如智能移动终端(智能手机、平板电脑等)、智能家电设备、智能办公设备等。
其中,目标应用程序是指与路由器101进行通信且可以对其进行控制的应用程序。
应当指出的是,在其他应用场景或实现方式中,也可以由互联网上的独立服务器或者局域网中的设备代替上述云服务器实现的功能,本公开实施例对此不作限定。
下面将结合图2对本公开实施例提供的方法进行详细说明。
如图2所示,本公开实施例提供的设备识别方法包括如下操作:
步骤201、在终端设备接入时,获取接入的该终端设备的设备标识信息和设备特征信息。
本公开实施例中,设备标识信息为区别不同终端设备的标识,接入同一设备的每个终端设备的设备标识信息各不相同。优选地,采用MAC地址作为设备标识信息,当然,也可以采用其他信息作为设备标识信息。
具体地,路由器(或其他设备)在检测到有终端设备接入后,即对该终端设备事实上报的通信消息(如HTTP报文)进行解析,从中获取设备标识信息和设备特征信息。
本公开实施例中,设备特征信息是指能够反映设备信息的信息,例如主机名(Hostname)、用户代理(user agent)信息、DNS信息等等。
本公开实施例中,优选地,仅在终端设备首次接入时,获取其设备标识信息以及设备特征信息。由于在该终端设备首次接入后,通过下图3所示的过程可以有效识别出其完整的设备信息并保存到设备信息库中,因此,后续该终端设备再次接入时,仅获取其设备标识信息即可实现设备识别。
采用以下至少一种识别方式对接入的终端设备进行识别:
步骤202a、在设备信息数据库中查找接入的上述终端设备的设备标识信息关联的设备信息,获取查找到的设备信息作为接入的该终端设备的设备信息;
步骤202b、利用预定的正则规则集对上述设备特征信息进行匹配,根据匹配结果获取接入的上述终端设备的设备信息。
应当指出的是,本公开实施例不对步骤202a和步骤202b的执行顺序进行限定。由于设备信息数据库的查询结果更准确、全面,且查询速度较快,优选地,首先执行步骤202a,在没有识别到设备信息时,继续执行步骤202b,如果通过步骤202a得到设备信息,则不执行步骤202b。当然,也可以并行 执行步骤202a和步骤202b,将最先输出的设备信息作为上述终端设备的设备信息。
本公开实施例中,优选地,上述步骤202a和步骤202b在云端服务器执行,以提高处理速度。当然,上述步骤202a和步骤202b也可以在其他设备上实现,例如,通过扩充路由器的内存,在路由器上实现上述步骤202a和步骤202b;又例如,在系统中增设设备识别服务器(局域网或互联网上的独立服务器而非云服务器),通过该设备识别服务器执行步骤202a和步骤202b。
其中,如图3所示,设备信息数据库采用以下方式更新:
步骤301、获取已接入的各个终端设备的设备标识信息,并按照预定的规则获取已接入的各个终端设备的多条用户代理信息。
具体地,以图1所示的系统为例,由路由器执行该步骤301,并将获取的信息上报。
其中,设备标识信息可以在终端设备进行接入认证时获取,也可以从终端设备上报的通信消息(如HTTP报文)中获取。若从终端设备上报的通信消息中获取,既可以仅获取一次,也可以在每次获取用户代理信息时一并获取设备标识信息。
本公开实施例不对上述预定规则进行限定,在实际应用中,可以根据具体应用场景的需要制定预定规则,例如,持续获取已接入的各个终端设备的预定数量的用户代理信息。
本公开实施例不对预定数量进行限定,实际应用中,可以根据实际需要或者经验确定。优选地,该预定数量为200条。
步骤302、利用获取的多条用户代理信息识别已接入的各个终端设备,得到已接入的各个终端设备的设备信息,并将已接入的各个终端设备的设备标识信息与各自的设备信息关联保存到设备信息数据库。
本公开实施例中,优选地,设备信息数据库保存在云端。当然,设备信息数据库也可以保存在本地,例如,为路由器扩展内存,将设备信息数据库保存在扩展内存中,又例如,在局域网内添加存储设备,将设备信息数据库保存在该存储设备中。
本公开实施例中,优选地,上述步骤302在云端服务器执行,以提高处理速度。当然,上述步骤302也可以在其他设备上实现,例如,通过扩充路由器的内存,在路由器上实现上述步骤302;又例如,在系统中增设设备识别服务器(局域网或互联网上的独立服务器而非云服务器),通过该设备识别服务器执行步骤302。
本公开实施例提供的方法,预先建立设备信息数据库,并利用已接入的终端设备的多条用户代理信息获取设备信息,将设备标识信息与设备信息关联保存到设备信息数据库中。通过多条用户代理信息获取设备信息,可以降低甚至避免用户代理信息修改而无法获取设备信息的情况。基于此,在对终端设备进行识别时,不仅可以采集终端的设备特征信息,并利用正则规则集 匹配获得设备信息,还可以采集终端设备的设备标识信息,并据此查找设备信息数据库获取设备信息。本公开实施例并非利用单一识别方式进行设备识别,而是结合设备信息数据库进行设备识别,提高了设备识别率。
本公开实施例中,通过图2所示的处理过程得到的设备信息可以直接输出并展示给用户。但通过设备特征信息识别到的用户信息往往由于映射规则不同、各个终端设备生产厂商的信息格式不同等原因,存在格式不统一,且信息表示不直观,使得用户难以快速根据设备信息确认终端设备的问题。
为此,一种实现方式中,可以预先建立映射规则以对设备信息进行标准化处理。具体地,可以在识别过程中或者在建立规则库、数据库时即进行标准化处理,也可以在利用图2所示的方法得到设备信息后进行标准化处理。
以后者为例,采用任意一种识别方式对接入的终端设备进行识别之后,按照预定的映射规则对接入的终端设备的设备信息进行标准化处理;通过安装有目标应用程序的终端设备输出标准化处理后的设备信息。
本公开实施例中,映射规则反映了标准化之前的设备信息与标准化之后的设备信息的对应关系。例如,标准化之前的设备信息为:APPLE(设备品牌),对应的标准化之后的设备信息为:苹果(设备品牌);又例如,标准化之前的设备信息为:PHONE(设备类型),对应的标准化之后的设备信息为:手机(设备类型);还例如,标准化之前的设备信息为:A1660(设备型号),对应的标准化之后的设备信息为:苹果7(设备型号)。
为进一步提高可视化水平,标准化之后的设备信息还包括设备图形。例如,品牌图标、类型图标、型号图标等。
本公开实施例中,不同的设备信息的粒度不同。以品牌、类型、型号为例,其中,品牌的粒度最大,型号的粒度最小,在标准化处理过程中,选择粒度最小的设备信息对应的设备图形添加到最终输出的标准化设备信息中。
本公开实施例提供的方法按照预定的映射规则对设备信息进行标准化处理,标准化处理后的设备信息格式统一,且信息表达方式直观,例如采用用户母语作为表达方式等等,将标准化处理后的设备信息在指定显示屏上显示,便于用户快速确认终端设备。
在上述任意方法实施例的基础上,上述步骤202b的实现方式有多种。
其中,若设备特征信息为单一设备特征信息,例如UA信息或HOSTNAME信息,则可以利用该单一设备特征信息对应的正则规则集对其进行匹配。
为了提高识别率,优选地,设备特征信息通常包括多种。实际应用中,为提高数据处理效率,需要对设备特征信息的数据格式进行定义,本公开实施例不对设备特征信息的数据格式进行限定,可以根据实际需要确定。作为举例而非限定,设备特征信息包括如下两个字段:UA信息字段和HOSTNAME信息字段。以UA信息字段为例,UA信息字段的取值为空,表示没有获取到UA信息,若不为空,其取值即为UA信息。
相应地,若设备特征信息中包括多种信息,优选地,上述步骤202b具体是利用多个正则规则集分别对接入的终端设备的设备特征信息中的部分或全部信息进行匹配,分别得到每个正则规则集的匹配结果,匹配成功的匹配结果包括设备信息;若至少一个正则规则集匹配成功,根据各个正则规则集的匹配结果及预定的可信度权重调整规则确定各个匹配结果的可信度权重;根据每个匹配结果的可信度权重对各个匹配结果进行融合,得到接入的终端设备的设备信息。
本公开实施例中,如上所述,设备信息也可以包括多种,相应地,设备信息的数据格式可以包括多个字段,每个字段的取值对应一种设备信息。上述根据每个匹配结果的可信度权重对各个匹配结果进行融合,得到终端设备的设备信息,其具体实现方式可以是:查找设备信息的各个字段的目标字段取值,目标字段取值为目标匹配结果中包含的目标字段的取值,目标匹配结果为所有包括目标字段的匹配结果中可信度权重最高的匹配结果。
进一步地,若所有正则规则集均匹配失败,将接入的终端设备的设备特征信息输入设备识别模型,利用设备识别模型得到接入的终端设备的设备信息,设备识别模型是利用设备特征样本信息训练得到的,设备特征样本信息包括设备特征信息和表示设备信息的标签。
在上述任意方法实施例的基础上,对接入的终端设备进行识别,还包括:
将接入的终端设备的设备标识信息与通过查找预先建立的缓存数据库中的设备标识信息进行匹配;
若匹配成功,根据匹配结果获取接入的终端设备的设备信息。
优选地,上述处理过程在步骤202a和步骤202b之前执行。
本公开实施例不对缓存数据库的数量以及存储位置进行限定。在一种实现方式中缓存数据库包括设备信息缓存数据库和/或特征信息缓存数据库,设备信息缓存数据库中关联保存设备标识信息和设备信息,特征信息数据库中关联保存设备标识信息和设备特征信息。
其中,上述两个缓存数据库可以均保存在云端,也可以保存在本地。
具体实现过程中,可以同时利用这两个缓存数据库进行识别,也可以按照预定的执行顺序依次利用这两个缓存数据库进行识别。
进一步地,若与设备信息缓存数据库中的设备标识信息匹配成功,根据匹配结果获取终端设备的设备信息的实现方式可以但不仅限于:从设备信息缓存数据库中获取设备标识信息关联的设备信息作为终端设备的设备信息;
若与特征信息缓存数据库中的设备标识信息匹配成功,根据匹配结果获取终端设备的设备信息的实现方式可以但不仅限于:从特征信息缓存数据库中获取设备标识信息关联的设备特征信息;利用预定的正则规则集合对获取的设备特征信息进行匹配;若匹配成功,获取匹配得到的设备信息作为终端设备的设备信息。
在上述任意利用缓存数据库进行设备识别的实施例中,利用设备标识信 息和设备特征信息对终端设备进行识别,得到终端设备的设备信息之后,一种实现方式中,从设备信息中检测到目标信息后,将设备信息和设备标识信息关联保存到设备信息缓存数据库,另一种实现方式中,从设备信息中检测到目标信息,将设备标识信息和设备特征信息关联保存到特征信息缓存数据库中。
优选地,若利用上述设备信息数据库匹配成功,则将设备信息和设备标识信息关联保存到设备信息缓存数据库;若利用其他方式匹配成功,从设备信息中检测到目标信息,将设备标识信息和设备特征信息关联保存到特征信息缓存数据库中。其中,目标信息可以但不仅限于是设备品牌、设备类型和设备型号。
在上述任意方法实施例的基础上,还可以引入纠错功能。具体地,若检测到预定的纠错触发条件被触发,向纠错处理客户端发送纠错请求消息,纠错请求消息中包括接入的终端设备的设备标识信息和设备特征信息,还包括触发纠错触发条件的信息;接收纠错处理客户端返回的纠错指令,并根据纠错指令的指示执行以下至少一种操作:
对至少一个可信度权重调整规则进行调整;
更新至少一个正则规则集中的正则规则;
更新至少一个映射规则。
其中,纠错触发条件包括以下至少一条:
条件1、接入的终端设备的设备信息不包括目标信息;
条件2、接收到目标应用程序反馈的设备信息修正消息,设备信息修正消息中携带修正后的设备信息。
相应地,上述触发该条件1的信息为指示识别到的设备信息不完整的信息;
上述触发该条件2的信息为指示识别到的设备信息不正确的信息。
下面以一具体实施例对实现本公开实施例提供的方法的软件架构进行说明,应当指出的是,该实施例提供的软件架构仅作为举例而非限定,实际应用中,可以根据具体场景需要和/或硬件设备的条件限制等搭建不同功能模块划分方式的软件架构,本公开实施例对此不作限定。
如图4所示,本实施例提供的软件架构包括如下部分:
数据采集
以图1所示的系统为例,由路由器进行数据采集。在该实施例中,数据采集过程分为两部分,一部分为线下数据采集,一部分为在线数据采集。
其中,线下数据采集过程是指路由器持续对已接入的终端设备的UA信息进行预定数量的采集,并将采集到的UA信息上报到云端。
其中,在线数据采集是指终端设备首次连接到路由器时,路由器采集该终端设备实时上报的多字段信息,例如:mac,hostname,user-agent,op60等,并将这些信息上报给云端进行识别。
本公开实施例中,若云端为每个路由器独立维护缓存数据库,那么,对于首次接入路由器的终端设备,其设备信息不可能出现在缓存数据库中,因此,路由器具体是将在线采集到的信息上报给云端的在线设备识别引擎。若云端在维护缓存数据库时,可根据多个路由器上报信息的识别结果维护同一个缓存数据库,那么,即使某终端设备首次接入路由器A,但其曾经接入过路由器B,而缓存数据库与这两个路由器均关联,那么,路由器可以先将在线采集到的信息上报给云端的缓存数据库。
云查缓存
云查缓存机制是基于预先建立的缓存数据库,构建缓存查询机制和缓存回收机制。
当接收到路由器上报的信息时,通过匹配缓存数据库,实现快速、精准识别设备。与此同时,建立的缓存机制可以有效防止上报数据前后不一致倒是设备识别失败等情况。
若通过云查缓存机制获得设备信息,则直接将设备信息输入知识库进行标准化处理并输出;否则,将路由器上报的信息发送给在线识别引擎继续进行设备识别处理。
相应地,上述缓存回收机制是指,若在线识别引擎识别到的设备信息包括设备品牌、设备类型和设备型号,将对应的上报信息(mac,hostname,ua等)保存到缓存数据库中,以扩充缓存数据库。
线下识别引擎
按照预定的时间周期(例如以一个自然日为周期),将线下采集并存储到云端的UA信息进行设备识别,将识别到的设备信息以及对应的设备标识信息关联保存到设备信息数据库中。
其中,利用上述UA信息进行设备信息识别的实现方式可以是:通过比较UA信息,从中获取有效UA信息;解析有效UA信息得到设备信息。
具体地,通过比较UA信息,获取重复数量最多的UA信息作为有效UA信息,重复数量是指信息内容完全相同的UA信息的数量。
其中,解析有效UA信息得到设备信息的实现方式可以是:从有效UA信息中提取目标关键字;根据预先建立的目标关键字与设备信息的关联关系,获取提取的目标关键字关联的设备信息作为终端设备的设备信息。
在线设备识别引擎
在线设备识别引擎是接收路由器实时采集的数据信息(路由器直接上报或经云查缓存后输入)进行识别,并将识别结果输出给下一级进行标准化处理。
其中,在线设备识别引擎具体采用如下四种设备识别方式:
基于设备信息数据库进行匹配识别,其识别得到的设备信息包括设备品牌、设备类型和设备型号;
基于Hostname正则规则库进行匹配识别,其识别得到的设备信息包括 设备品牌和设备类型,可选地包含设备型号;
基于UA正则规则库进行匹配识别,其识别得到的设备信息包括设备品牌和设备型号;
基于设备识别模型进行匹配识别,其识别得到的设备信息包括设备品牌和设备类型。
其中,基于hostname正则规则集、基于ua正则规则集和/或基于设备识别模型得到的设备信息需经过融合后输出。
知识库
接收在线识别引擎输出的设备信息后,将设备信息进行标准化处理,并输出给前端(目标应用程序)进行展示。
其中,假设在线识别引擎输出的设备信息为:品牌:huawei,型号:MLAUL00。
通过标准化后输出结果:品牌:华为,型号:麦芒5。
纠错学习
若在线识别引擎的识别结果有误,那么终端设备的信息会进入“智能产品-纠错学习平台”,进行人工校验。基于校验结果,反向扩充知识库、更新hostname和UA正则规则库。待规则更新后,重新对该设备进行识别,输出正确的识别结果。由此形成设备识别闭环(识别出错–识别校验–模型更新–识别准确)。
应当指出的是,进行设备识别的目的是向用户展示设备信息,因此,可以在用户打开目标应用程序(或者在用户调用目标应用程序的相关展示界面时),该目标应用程序发出设备信息请求消息,根据该设备请求消息进行实时信息采集以及设备识别。当然,为提高展示速度,也可以在接入的终端设备连接后,即对其进行设备识别,并将识别到的设备信息推送给目标应用程序保存在本地,目标应用程序在需要展示时,从本地调取设备信息进行展示。
若通过纠错对设备信息进行了更新,那么,目标应用程序(即前端)展示更新后的设备信息。
本公开实施例还提供一种终端设备识别系统,如图5所示,包括:
信息获取单元501,用于在终端设备接入时,获取接入的终端设备的设备标识信息和设备特征信息;
设备识别执行单元502,用于采用以下至少一种识别方式对接入的终端设备进行识别:
在设备信息数据库中查找接入的终端设备的设备标识信息关联的设备信息,获取查找到的设备信息作为接入的终端设备的设备信息;
利用预定的正则规则集对设备特征信息进行匹配,根据匹配结果获取接入的终端设备的设备信息;
设备信息数据库更新单元503,用于获取已接入的各个终端设备的设备标识信息,并按照预定的规则获取已接入的各个终端设备的多条用户代理信 息;利用获取的多条用户代理信息识别已接入的各个终端设备,得到已接入的各个终端设备的设备信息,并将已接入的各个终端设备的设备标识信息与各自的设备信息关联保存到设备信息数据库。

若至少一个正则规则集匹配成功,根据各个正则规则集的匹配结果及预定的可信度权重调整规则确定各个匹配结果的可信度权重;
根据每个匹配结果的可信度权重对各个匹配结果进行融合,得到接入的终端设备的设备信息。
可选地,若所有正则规则集均匹配失败,设备识别执行单元还用于:

可选地,设备识别执行单元还用于:
将接入的终端设备的设备标识信息与通过查找预先建立的缓存数据库中的设备标识信息进行匹配;
若匹配成功,根据匹配结果获取接入的终端设备的设备信息。

若检测到预定的纠错触发条件被触发,向纠错处理客户端发送纠错请求消息,纠错请求消息中包括接入的终端设备的设备标识信息和设备特征信息,还包括触发纠错触发条件的信息;
