本步骤中, 用户终端设备根据搜索得到的服务网络信息, 配置自身为 站 (STA, Station )模式, 设置网络 ID, 并向服务网络的中心节点 (作为 服务网络的接入节点)发送动态地址获取请求, 获取服务网络的中心节点 为该用户终端设备分配的 IP地址并完成配置。 中心节点需要支持动态主机 设置协议 ( DHCP, Dynamic Host Configuration Protocol )。
步骤 104, 用户终端设备与服务网络内的节点进行交互, 共同完成统一 业务提供。
如果一项业务提供需要借助服务网络的中心节点的服务能力, 则用户 终端设备与中心节点进行交互, 共同完成统一业务提供; 如果一项业务提 供还需要借助服务网络内的其他节点的服务能力, 则用户终端设备还需要 与其他节点进行交互, 共同完成统一业务提供。
步骤 105,判断不存在具备用户终端设备完成业务所需服务能力的服务 网络时, 用户终端设备从未加入服务网络的、 且具备用户终端设备完成业 务所需服务能力的设备中选取中心节点。
本步骤中, 用户终端设备从搜索的未加入服务网络的设备中, 选择具 备用户终端设备完成业务所需服务能力的设备, 参加中心节点选举; 中心 节点的选取可以根据各设备信息采用协商的方式进行, 如中心节点的选取 可采取随机选取方式、 基于博弈论的竟争选取方式、 轮训选举方式等多种 实现方式。
例如: 中心节点的选取策略为 "处理能力最强", 则根据参加选举的设 备的处理能力, 基于竟争选取方式, 选择处理能力最强的设备作为中心节 点。
步骤 106, 根据选取的中心节点配置生成服务网络。
用户终端设备将选取的中心节点配置为接入点 (AP )模式, 形成服务 网络, 所述中心节点开启动态地址分配服务, 打开动态地址分配端口, 为 动态地址分配做好准备; 用户终端设备配置为 STA模式, 设置网络 ID, 并 向选取的中心节点发送动态地址获取请求, 获取所述中心节点分配的 IP地 址并完成配置。 选取的中心节点需要支持 DHCP。 步骤 107, 广播服务网络信息, 邀请其它设备加入。
本步骤为可选操作, 中心节点配置为 AP模式后,修改或更新其所提供 的服务标号, 并广播该中心节点的服务网络信息(包括中心节点 ID号、 所 提供的服务标号); 其他设备在搜索周边时即可搜索到该服务网络。
如果统一业务的完成还需要其他设备的协同, 则需要协同的设备可以 在搜索到该服务网络后请求加入, 或者该服务网络主动邀请需要协同的设 备力口入。
通过上述方法, 用户终端设备在进入服务设备分布的区域时, 可以自 主完成服务发现和网络的配置, 自主地聚合一定区域内的设备能力, 通过 多个设备的协同配合完成统一业务提供, 从而满足用户的最佳服务体验。
对应本发明实施例的设备和服务的发现方法, 本发明的另一实施例还 提供了一种用于设备和服务发现的设备中间件。 如图 2 所示, 设备中间件 10位于网络层和媒体接入控制 ( MAC, Media Access Control )层之间; 本 发明实施例基于跨层思想, 设备中间件 10通过多个模块与应用层、 网络层 和 MAC层进行信息交互, 完成设备、 服务发现及网络配置过程。 设备中间 件 10包括: 服务查询及调用模块 11、 信息广播及搜索模块 12和网络配置 模块 13。
其中, 服务查询及调用模块 11, 配置为通过与应用层交互, 向应用层 查询用户终端设备的设备信息和服务能力信息; 服务查询及调用模块 11提 供 API接口 (应用程序接口), 应用层通过对 API接口的调用, 将用户终端 设备的设备信息和服务能力信息输入设备中间件 10的服务查询及调用模块 11。 此外, 当应用层有设备信息和服务能力信息变更时, 需要调用所述 API 接口将最新的设备信息和服务能力信息以事件通知的方式输入到设备中间 件 10的服务查询及调用模块 11, 以供设备和服务发现使用。
信息广播及搜索模块 12, 配置为控制 MAC层广播用户终端设备的设 备信息和服务能力信息, 并搜索周边的服务网络信息、 未加入服务网络的 设备信息和设备的服务能力信息。
网络配置模块 13, 配置为通过与网络层交互, 完成网络配置过程, 包 括中心节点选取、 网络自组织生成、 节点参数自动配置 (包括网络类型、 网络 ID、 IP地址)等等; 具体的:
在信息广播及搜索模块 12搜索到周边存在具备用户终端设备完成业务 所需服务能力的服务网络时, 网络配置模块 13将所述用户终端设备配置加 入所述服务网络, 并与所述服务网络的中心节点进行交互完成业务; 在信 息广播及搜索模块 12搜索周边不存在具备用户终端设备完成业务所需服务 能力的服务网络时, 网络配置模块 13从未加入服务网络的、 且具备完成业 务所需服务能力的设备中选取中心节点, 并根据选取的中心节点配置生成 服务网络, 与选取的中心节点进行交互完成业务。
较佳的, 网络配置模块 13还配置为, 通过以下方式将所述用户终端设 备配置加入所述服务网络:
配置所述用户终端设备为站 STA模式, 设置网络 ID, 并向所述服务网 络的中心节点发送动态地址获取请求, 获取所述服务网络的中心节点为所 述用户终端设备分配的 IP地址。
较佳的, 网络配置模块 13还配置为, 通过以下方式, 根据选取的中心 节点配置生成服务网络:
将选取的中心节点配置为 AP模式,所述中心节点开启动态地址分配服 务, 打开动态地址分配端口;
配置所述用户终端设备为 STA模式, 设置网络 ID, 并向选取的中心节 点发送动态地址获取请求, 获取所述中心节点为所述用户终端设备分配的 IP地址。
另外, 网络配置模块 13可采取随机选取方式、 基于博弈论的竟争选取 方式、 轮训选举方式等多种实现方式, 来进行中心节点的选取。 下面再结合图 2 所示的设备中间件结构, 对本发明实施例中利用设备 中间件发现周边设备及服务, 并完成业务提供的方法流程进行详细阐述, 如图 3所示, 该流程主要包括以下步骤:
步骤 301,设备中间件的服务查询及调用模块向应用层发送查询设备及 服务能力信息的请求消息。
步骤 302,应用层调用设备中间件的 API接口填写请求的用户终端设备 的设备信息和服务能力信息, 并发送给设备中间件。
本步骤中, 当设备信息及服务能力信息发生变更时, 应用层需要调用 设备中间件提供的 API接口, 将最新的设备信息和服务能力信息以事件通 知的方式输入到设备中间件, 以供设备和服务发现使用。
步骤 303,设备中间件封装获取的设备信息及服务能力信息, 并通过信 息广播及搜索模块向 MAC 层发出广播设备信息及服务能力信息的请求消 息。
步骤 304, 信息广播及搜索模块向 MAC层发出搜索周边服务网络、 未 加入服务网络的设备及设备的服务能力信息的请求消息。
需要说明的是, 步骤 303、 304的执行先后顺序没有严格的要求, 可以 同时进行。
步骤 305, MAC层完成信息广播及搜索, 向设备中间件返回搜索结果。 搜索结果包括: 周边的服务网络信息、 未加入服务网络的设备信息及 设备的服务能力信息。
步骤 306,设备中间件的服务查询及调用模块将搜索结果进行筛选并上 传至应用层。
所述筛选, 是根据业务需求, 从搜索结果中筛选满足业务需求的结果。 步骤 307,设备中间件的网络配置模块根据所获取的信息(即服务查询 及调用模块上传的搜索结果) 完成自组织组网, 生成网络参数并对网络中 的节点进行网络配置。
步骤 308, 应用层根据应用 (即业务需求)填充 Socket套接, 以供网 络层连接使用。
步骤 309,网络层通过 MAC层向指定网络中心节点发送网络连接请求。 如图 4所示是一个利用本发明实施例的方法进行业务提供的实施例示 意图。
如图 4所示, 用户携带移动终端进入办公区域, 通过广播消息搜索到 区域中的笔记本、 投影仪和打印机设备, 自动配置形成面向用户业务需求 的办公网络, 用户携带的文件可以在笔记本电脑上进行修改, 可以通过打 印机享受打印服务, 也可以通过投影仪将文件投至显示屏上进行显示。 以在用户设备进入服务设备分布的区域时, 自主完成服务发现及网络的配 置, 自主地聚合一定区域内的设备能力, 通过多个设备的协同配合完成统 一业务提供。 由于设备发现与服务发现同时进行, 实现了服务能力的透明 访问, 省去了用户配置的繁瑣过程, 可以满足用户的最佳服务体验。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
