摘要:
PURPOSE: A call setup method for a PTT(Push-To-Talk) service in a cellular mobile communication system is provided to transmit a PTT signaling message while previously attempting a traffic channel setup, and to load the PTT signaling message on an origination message or a reconnect message, thereby reducing a delay caused by a PTT signaling message exchange. CONSTITUTION: When a traffic channel is not connected, a talker transmits a PTT request message to a PTT server through an R-EACH(Reverse-Extended Access Channel)(310), and immediately starts a setup procedure of the traffic channel(320). The PTT server transmits a PTT confirm message to ring an approval tone(330), and transmits an SDB-type PTT request message to listeners(340). The listeners perform a re-inactivation procedure with a wireless access network by responding to the PTT request message(350), and transmits a PTT confirm message to the PTT server when a setup of the traffic channel is completed(360). Voice packets are transceived between the talker and the PTT server(370) and between the PTT server and the listeners(380).
摘要(中):
目的:提供一种用于蜂窝移动通信系统中的PTT(即按即说)服务的呼叫建立方法,用于在先前尝试业务信道建立时发送PTT信令消息,并将PTT信令消息加载在发起消息上 或重新连接消息,从而减少由PTT信令消息交换引起的延迟。 构成:当没有连接业务信道时,说话者通过R-EACH(反向扩展接入信道)(310)向PTT服务器发送PTT请求消息,并立即开始业务信道(320)的建立过程, 。 PTT服务器发送PTT确认消息以振铃批准音(330),并向收听者(340)发送SDB型PTT请求消息。 收听者通过响应PTT请求消息(350)执行无线接入网络的重新失活过程,并且当业务信道的建立完成时,向PTT服务器发送PTT确认消息(360)。 语音分组在讲话者和PTT服务器(370)之间以及PTT服务器和听众(380)之间被收发。
