该实施例通过扩展 SIP中 INFO消息体的 Command操作标识，定义一个或者 两个不同的 Command操作标识，参见 INFO消息 Command命令示例说明 ,由 Call AS根据 INFO消息中的扩展 Command命令标签进行判断， 并实现同号软终端与 移动终端通话切换过程。
其中， INFO消息扩展 Command标签示例：

该标签可自定义， 可自定义一个或两个不同命令标签， 例如定义标签 4001 , 表 示需要将通话切换到与软终端同号的移动终端或者客户端上； 或者定义标签 4001 , 表示需要将通话切换到与软终端同号的移动终端上， 而定义标签 4002， 表示需要将通话切换到与移动终端同号的软终端上。
整个通话切换包含两个主要流程： 一是呼叫前转流程， 即 PC客户端将正 在进行的通话切换到同号移动终端上； 另一是呼叫转入流程， 即与移动终端同 号的 PC客户端将同号移动终端正在进行的通话切换到同号 PC客户端上。 两种 切换流程都是通过在与移动终端同号的 PC客户端上一个按键或者两个按键操 作实现。
下面分别对两个流程实现进行详细描述。
本发明实施例一中， 呼叫前转（PC2Phone )流程图如图 2所示， 用户 B 与 PC客户端与移动终端同号用户 A (移动终端号码： 13812345678 )进行通 话， 用户 A通过 PC客户端与用户 B通话。 包括以下步骤：
步骤 s201 , 用户 A点击 PC客户端切换按键， 通过软交换向 Call AS发送 切换 INFO消息。
步骤 s202, Call AS收到 PC客户端发起的切换 INFO消息， 解析消息体中 Command标签， 确认该标签为呼叫前转请求， 随后通过软交换 /SG向 PC客户端 同号的移动终端 AJ ^起呼叫， 同时 Call AS仍然保持用户 A的 PC客户端与用户 B 的通话。

步骤 s203 , Call AS查询用户 A的同号移动终端 A物理号码， 并发起呼叫： 如果用户 A的移动终端 A状态不可用 （无信号、 关机等） ， 则结束本次切换请 求，用户 A的 PC客户端 A呼叫不释放；如果用户 A的移动终端 A正常并有回铃音， 此时 Call AS需要向被叫屏蔽用户 A的移动终端 A回铃音， 进入步骤 s204;
步骤 s204, 用户 A的移动终端 A振铃并接听； Call AS接收用户 A的移动终 端应答消息， Call AS建立用户 A同号移动终端 A与用户 B话路， 并释放用户 A 的 PC客户端 A与用户 B通话。
步骤 s205, 用户 A通过与其 PC客户端 A同号的移动终端 A与用户 B通 话。
根据本发明实施例一，呼叫前转流程信令流程如图 3所示， 包括以下步骤： 步骤 s301 , 用户 Α通过 PC客户端 A向软交换发送携带呼叫切换的 Command 标签的 INFO消息。
步骤 s302, 软交换将 INFO消息转发到 Call AS。
步骤 s303 , Call AS判断 INFO消息中扩展的 Command标签为 xxx, 识别为 呼叫前转命令， 则通过软交换下发 INVITE消息， 呼叫 A的同号移动终端（例如 13812345678 ) 。
步骤 s304, 软交换通过 SG将呼叫用户 A的移动终端 A的 SIP的 INVITE消息 转化为 SS7的 IAI消息， 并向目标 GMSC/MSC (移动关口局 /移动交换机）发送 IAI消息。
步骤 s305, GMSC/MSC呼叫用户 A的移动终端 A。
步骤 s306 , 用户 A通过同号移动终端 A应答， 并回复 ANM应答消息给 GMSC/MSC。
步骤 s307, GMSC/MSC通过 SG回复 ANM消息给软交换；
