    • In an embodiment, a call originator sends, to an application server, a request to initiate a given communication session with at least one call target, the received request configured to indicate to the application server that the given communication session is associated with a high-priority. The application server configures a call announcement to force the at least one call target to accept the given communication session, and transmits the configured call announcement to the at least one call target. The at least one call target receives the call announcement, and determines that the call announcement is configured to force the given access terminal to accept the given communication session. Responsive to the determination, the at least one call target transmits an acknowledgment to the call announcement that indicates that the at least one call target has accepted the given communication session.
    • 在一个实施例中,呼叫发起者向应用服务器发送与至少一个呼叫目标发起给定通信会话的请求,所述接收到的请求被配置为向应用服务器指示给定通信会话与高通 优先。 应用服务器配置呼叫通知以迫使至少一个呼叫目标接受给定的通信会话,并将配置的呼叫通知发送到至少一个呼叫目标。 所述至少一个呼叫目标接收所述呼叫通知,并且确定所述呼叫通知被配置为强制给定接入终端接受给定的通信会话。 响应于确定,所述至少一个呼叫目标向呼叫公告发送指示所述至少一个呼叫目标已经接受给定通信会话的确认。

    • In an embodiment, a given access terminal (AT) detects a request to initiate a Push-to-Talk (PTT) session, and stores first time information indicative of when the request to initiate the PTT session is detected. The given AT sends the request as a message to an access network, which forwards an announce message to announce the PTT session to a plurality of access terminals. At least one of the plurality ATs accepts the announce message to join the PTT session, and the access network sends a message to the given AT granting permission to begin the PTT session. The given AT stores second time information indicative of when the permission is received, and sends PTT latency information based on the first and second time information to the access network, the PTT latency information related to an initial PTT latency of the PTT session.
    • 在一个实施例中,给定的接入终端(AT)检测到发起一键通(PTT)会话的请求,并且存储指示何时检测到发起PTT会话的请求的第一时间信息。 给定的AT将请求作为消息发送到接入网络,该接入网转发通告消息以向多个接入终端通知PTT会话。 多个AT中的至少一个接受该通知消息以加入PTT会话,并且接入网向给定的AT发送一个消息以允许开始PTT会话。 给定的AT存储指示何时接收许可的第二时间信息,并且基于第一和第二时间信息向接入网络发送与PTT会话的初始PTT等待时间相关的PTT等待时间信息。
