Abstract: A user equipment (UE) detects a change in one or more criteria, determines whether a severity of the potential loss of network service is above a severity threshold, transmits a ping to a server to which the UE was connected before detecting the potential loss of network service based on the severity of the potential loss of network service being above the severity threshold, and blocks transmission of a ping to the server based on the severity of the potential loss of network service not being above the severity threshold. A server attempts unsuccessfully to connect received call requests to the UE, transmits one or more pings to the UE, and changes a presence status of the UE to indicate that the UE is likely not reachable based on not receiving a response to the one or more pings from the UE before transmitting a threshold number of pings.

Abstract translation: 用户设备（UE）检测一个或多个标准的变化，确定网络服务的潜在丢失的严重程度是否高于严重性阈值，在检测到UE的潜在丢失之前将ping发送到与UE相连的服务器 基于网络服务潜在损失严重程度的网络服务高于严重性阈值，并根据网络服务潜在丢失的严重程度阻止对服务器的Ping传输不高于严重性阈值。 服务器尝试不成功地将接收的呼叫请求连接到UE，向UE发送一个或多个呼叫，并且基于未接收到对该一个或多个呼叫的响应来改变UE的存在状态以指示UE可能不可达 在发送阈值数量的呼叫之前，来自UE的ping。
