Description

信息同步方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种信息同步方法及装置。
背景技术
在AllJoyn系统中，用户能在近端网络(例如，家庭网络)中使用其AllJoyn设备享受AllJoyn服务。而AllJoyn网关代理(Gateway Agent，简称为GA)使用户能在离开近端网络时无缝体验AllJoyn服务。为此，用户在近端网络中设置可远程访问的服务列表，包括设备、应用(Application，简称为App)、接口，之后，用户通过云服务器(Cloud Service，简称为CS)远程访问AllJoyn服务。
终端(例如，移动设备(Mobile Device，简称为MD))上的控制App使用户能够在近端网络之中设置远程配置文件，并且在离开近端网络后同样能够控制设备、接收通知，如同在近端网络之中。
GA与其CS连接的第三方协议由服务供应商指定。而GA中实现远程访问的组件包括：
网关管理App，实现控制App管理远程配置文件并曝露远程配置文件给连接器App；
连接器App，提供AllJoyn设备与CS的连接，同时提供AllJoyn和第三方协议间的协议转换；
控制App以基于通告的方式发现网关管理App，而网关管理App和连接器App经GA上预设的同一AllJoyn路由器进行相互通信。
当终端经由互联网远程控制近端网络中的设备时，需要通过CS来实现，此时，CS需要获取终端的上下文信息来处理终端的业务请求；而当终端回到近端网络后，用户不再希望连接互联网，需要直接通过GA来本地控制近端网络中的设备，此时，GA需要获取终端的上下文信息来处理 MD的业务请求。
但是，在相关技术中，由于终端远程访问AllJoyn服务时，仅CS获取了终端的上下文信息，GA中并没有终端的上下文信息，因此，当终端回到近端网络后，GA需要再通过中间网元从云服务器CS或者终端中获取终端上下文信息，在获取的过程中，会产生大量的信令开销，增加网络的负荷。

通过上述步骤，由于创建终端的上下文信息后，将该终端的上下文信息一并同步到网关代理中，无需网关代理GA再通过中间网元从云服务器CS或者终端中获取终端上下文信息，因此，可以解决相关技术中网关代理GA获取终端上下文信息的过程中，产生大量信令开销的问题，达到节省信令开销的效果。
可选地，根据第一上下文参数，创建终端的上下文信息包括：根据第一上下文参数在终端的原始资源中创建子资源，并根据第一上下文参数设置子资源的属性值。例如，可以通过如下方式实现：根据第一上下文参数创建该终端的原始资源的子资源<Contex>，并根据第一上下文参数设置该子资源<Contex>中属性值包括终端的上下文信息。
可选地，根据从第一上下文参数中获取的用于标识需要创建终端的上下文信息的网关代理的网关代理标识，向网关代理标识的网关代理发送第 二请求消息，包括：根据从第一上下文参数中获取的用于标识需要创建终端的上下文信息的网关代理的网关代理标识，向网关代理标识的网关代理发送创建子资源对应的通告资源的请求消息，其中，创建子资源对应的通告资源的请求消息用于请求网关代理创建子资源对应的通告资源，并根据请求消息设置通告资源的属性值为子资源的属性值。例如，可以通过如下方式实现：发送创建通告资源请求到该网关代理GA，使得网关代理可以根据该请求消息创建子资源<Contex>对应的通告资源，并根据该请求消息设置该通告资源<Contex>的属性值包括终端的上下文信息。

步骤S302，接收云服务器发送的用于请求创建终端的上下文信息的第二请求消息，其中，第二请求消息包括第三上下文参数；
步骤S304，根据第三上下文参数，创建终端的上下文信息。

可选地，根据第三上下文参数，创建终端的上下文信息包括：根据第三上下文参数创建终端的原始资源中子资源对应的通告资源，并根据第三上下文参数设置通告资源的属性值为终端的上下文信息，其中，终端的上下文信息为云服务器中终端的原始资源中子资源的属性值。例如，可以通过如下方式实现：网关代理可以根据该请求消息中包含的第三上下文参数创建子资源<Contex>对应的通告资源，并根据第三上下文参数设置该通告资源<Contex>的属性值包括终端的上下文信息。
可选地，接收云服务器发送的用于请求更新终端的上下文信息的第四请求消息，其中，第四请求消息包括第四上下文参数；根据第四上下文参数，更新本地存储的终端的上下文信息。通过上述步骤，实时更新终端的上下文信息，可以保证根据同步的终端上下文信息处理终端最新的业务请求。
可选地，根据第四上下文参数，更新本地存储的终端的上下文信息包括：根据第四上下文参数更新子资源对应的通告资源的属性值。例如，网关代理根据第四上下文参数更新子资源对应通告资源<Context>的属性值为更新后终端上下文信息。
可选地，检测到终端接入；根据本地存储的终端的上下文信息，对终端的业务进行处理。通过上述步骤，当终端进入近端网络后，网关代理 GA无需通过中间网元从云服务器CS或终端中同步上下文信息，直接从GA本地进行获取，从而节省了信令开销，提升了用户体验。
可选地，根据本地存储的终端的上下文信息，对终端的业务进行处理包括；根据子资源对应的通告资源的属性值，对终端的业务进行处理。例如，当终端进入近端网络后，网关代理需要获取终端的上下文信息时，在本地检索通告资源<Context>的属性值获取终端的上下文信息。
