    • Instant messaging clients transmit, to a server, presence information indicating that the respective client is in a communicative state in which the client is receptive to communicating with the other clients. A server determines, for each client, that the respective client is in a communicative state if presence information was received from the client over a preceding predetermined time period, and that the client is in an unknown state if presence information was not received from the client over the preceding predetermined time period. The communicative state and the unknown state are possible presence states of the clients. The server transmits a notification to a second client of the presence state of a first client when both the first client and the second client are in a communicative state. But the server refrains from transmitting the notification to the second client when the first client is in the unknown state.
    • 即时消息客户端向服务器发送指示相应客户端处于客户端接受与其他客户端通信的通信状态的呈现信息。 如果在先前的预定时间段内从客户端接收到存在信息,并且如果没有从客户端接收到存在信息,则客户机处于未知状态,则对于每个客户端,服务器确定相应客户端处于通信状态 超过上述预定时间段。 交往状态和未知状态是客户端的可能存在状态。 当第一客户端和第二客户端处于通信状态时,服务器向第二客户端发送第一客户端的存在状态的通知。 但是当第一个客户端处于未知状态时,服务器不会将通知发送给第二个客户端。
