    摘要: A user device automatically sends a presence message to a presence server when the user device is powered on. Thereafter, the user device may send a sleep message to the presence server upon power down or prolonged period of inactivity, or the device may be required to send periodic messages to the presence server to maintain it as being listed as an active device. The presence server is then used to manage communication with the user device based on the presence information.

    摘要翻译: 当用户设备通电时,用户设备自动向存在服务器发送存在消息。 此后,用户设备可以在掉电或长时间不活动时向存在服务器发送睡眠消息,或者可能需要该设备向存在服务器发送周期性消息以将其维护为被列为活动设备。 然后,存在服务器用于基于存在信息来管理与用户设备的通信。
