信息技术.UPnP设备体系结构.第16-10部分:低功率设备控制协议.低功率代理服务

[中文适用范围]： 本服务定义符合 UPnP 设备架构版本 1.0。该服务类型用于建模“基本电源管理代理”（BPMPX）功能能力。BPMPX 是 UPnP 服务和控制点的组合。作为控制点，代理发现并控制网络中运行的低功耗设备服务；作为 UPnP 代理服务，它向网络通告自身，并响应来自低功耗感知控制点的操作。BPMPX 的基本功能包括：接收来自电源管理 UPnP 设备的组播发现消息以了解其电源状态；发送组播或单播发现消息（如 M-SEARCH）以查询 UPnP 设备并跟踪其电源状态；发送由电源感知设备提供的 GetPowerManagementInfo 操作；当接收到来自低功耗感知控制点的 WakeupDevice 操作时，向指定的睡眠设备发送适当的唤醒消息；作为 UPnP 服务获取电源管理机制；发送 BPMPX 服务公告和 M-Search 回复；响应 SearchSleepingDevices 操作以提供网络中睡眠设备的信息；响应来自控制点的 Wakeup 操作（唤醒操作是针对低功耗设备的，而不是唤醒 BPMPX 本身）。 [外文原描述]： ISO/IEC 29341-16-10:2011(E) describes a service definition which is compliant with the UPnP Device Architecture version 1.0.service. This service-type enables modelling of "Basic Power Management Proxy" function capabilities. Basic Power Management Proxy (BPMPX) is a combination of UPnP service and a control point. As Control Point, Proxy discovers and controls Low Power Device services running in the network, and as UPnP Proxy service, it advertises itself to the network, and responds to actions from low power aware Control Point. [LPARCH] Basic functions that BPMPX does are as follows: - Receive multicast discovery messages from power managed UPnP devices in order to be. aware of their power states (i.e. the BPMPX will act as Control Point). - Send multicast or unicast discovery messages (i.e. M-SEARCH) to query UPnP devices and keep track of their power states (i.e. the BPMPX will act as Control Point). - Send GetPowerManagementInfo action to obtain power management mechanism provided by power-aware devices. - Should send the appropriate wakeup message to the specified sleeping device when it receives WakeupDevice action from power aware Control Point. [LPARCH]. Act as UPnP service. - Sending BPMPX service announcements and M-Search replies. - Respond to SearchSleepingDevices action to provide the information of sleeping devices in network. - Respond to Wakeup action from Control Point. (Wake up action is directed to the low power devices and not for waking up the BPMPX).
