当主叫用户在手机终端上发起语音呼叫时， 手机终端首先查询自身的 数据连接状态（包括蜂窝网和 WLAN连接）， 如果数据连接处于激活状态， 则向 PLMN网络发出语音呼叫信令消息的同时，也向 IP网络业务服务器发 出 IP业务查询消息， 其中， 携带有主叫方和被叫方电话号码。
IP网络业务服务器接收到手机终端发来的 IP业务查询消息后， 解析该 消息， 获取主、 被叫号码， 然后检查主被叫双方用户的业务权限和数据连 接状态， 如果双方用户都已注册 IP网络通话业务， 并且都处于数据连接激 活状态（包括蜂窝网和 WLAN连接）， 即双方都满足预设的通话切换条件。 此时 IP网络业务服务器分别向主、 被叫用户发送切换选择提示消息， 询问 双方用户是否愿意将原来的 PLMN语音电话业务切换为 IP网络语音电话业 务， 如果主、 被叫双方都选择切换到 IP网络语音电话业务， 则在主被叫双 方之间建立 IP网络连接通路， 同时通知主被叫手机终端。
主叫终端接收到通知后， 将原来的 PLMN网络语音呼叫断开， 开始基 于 http协议的网络通话， 从而实现将本该由 PLMN网络承载的语音电话业 务切换为 IP网络通话。
综上所述， 可见本发明实施例所述方法， 通过终端和 IP网络业务 务 器共同配合， 在用户发起基于 PLMN网络的语音电话时， 能智能判断当前 主被叫用户的 IP网络业务权限状态和数据连接状态， 并在主被叫双方的状 态均满足设定的切换条件时， 自动将 PLMN网络的语音电话业务切换至 IP 网络的语音电话业务， 通过 IP网络替代 PLMN网络承载本次通话， 从而达 到提高通话质量和节省话费的目的。
