When the call forwarding state is set, the voice gateway forwards the second incoming call command in response to the first incoming call command to the second called terminal, and determines whether the second called terminal is an available terminal, according to the judgment result, and according to The first incoming call instruction and the second incoming call instruction implement a voice call operation of the calling terminal and the available terminal, thereby implementing call forwarding of the terminal; in this embodiment, the terminal call transfer is implemented by using a voice gateway. The problem that the function of the terminal call transfer in the related art can only be realized through the soft switch server or the IP multimedia system is solved, so that the transfer of the terminal is more convenient and flexible, and no longer depends on the soft switch server or the IP multimedia system.

步骤S12:语音网关向第二被叫终端发送第二呼入指令。Step S12: The voice gateway sends a second incoming call instruction to the second called terminal.
此外,在本实施例中涉及到的语音网关判断第二被叫终端是否为可用终端的方式包括:In addition, the manner in which the voice gateway involved in the embodiment determines whether the second called terminal is an available terminal includes:
在第二被叫终端处于通话正常状态时,语音网关确定第二被叫终端为可用终端;在第二被叫终端处于通话异常状态时,语音网关确定第三被叫终端为可用终端,其中,第三被叫终端处于通话正常状态。When the second called terminal is in the normal state of the call, the voice gateway determines that the second called terminal is an available terminal; when the second called terminal is in the abnormal state of the call, the voice gateway determines that the third called terminal is an available terminal, where The third called terminal is in a normal call state.
基于本实施例中的在第二被叫终端通话正常时,则第二被叫终端为可用终端,因此,在本实施例中的一个可选实施方式中,依据第一呼入指令和第二呼入指令执行主叫终端和可用终端的语音通话操作可以通过如下方式实现:The second called terminal is an available terminal when the second called terminal is in a normal state in the present embodiment. Therefore, in an optional implementation manner in this embodiment, according to the first incoming call instruction and the second The incoming call instruction to perform the voice call operation of the calling terminal and the available terminal can be implemented as follows:
步骤S21:语音网关根据第二呼入指令建立第二被叫终端与主叫终端之间的通信链路;Step S21: The voice gateway establishes a communication link between the second called terminal and the calling terminal according to the second incoming call instruction.
步骤S22:语音网关激活主叫终端的呼入操作;Step S22: The voice gateway activates the incoming call operation of the calling terminal;
步骤S23:语音网关依据链路和第一呼入指令执行主叫终端和第二被叫终端的语音通话操作。Step S23: The voice gateway performs a voice call operation of the calling terminal and the second called terminal according to the link and the first incoming call instruction.
基于本实施例中的在第二被叫终端处于通话异常时,在本实施例中的一个可选实施方式中语音网关将响应于第一呼入指令的第二呼入指令转发给第二被叫终端之后,语音网关将第二呼入指令转发给第三被叫终端。In an optional implementation manner in this embodiment, the voice gateway forwards the second incoming call command in response to the first incoming call instruction to the second After the terminal is called, the voice gateway forwards the second incoming call command to the third called terminal.
对于本实施例中该第三被叫终端处于通话正常状态,因此,步骤S108中依据第一呼入指令和第二呼入指令执行主叫终端和可用终端的语音通话操作方式可以通过如下方式实现包括:In this embodiment, the third called terminal is in a normal call state. Therefore, the voice call operation mode of the calling terminal and the available terminal according to the first incoming call command and the second incoming call command may be implemented in the following manner. include:
步骤S31:语音网关根据第二呼入指令建立第三被叫终端与主叫终端之间的链路;Step S31: The voice gateway establishes a link between the third called terminal and the calling terminal according to the second incoming call instruction.

需要说明的是,本实施例中是以第三被叫终端处于正常状态时为例进行说明的,如该第三被叫终端也是处于通话异常时,语音网关会较该第二呼入指令转发到第四被叫终端,如果该第四被叫终端时处于正常通话状态,实现第四被叫终端与主叫终端的 通话连接与第三被叫终端与主叫终端通话连接时类似的;也就是说在该语音网关实现呼叫转移的过程中,主叫终端与可用终端实现通话的过程中,选择可用终端的过程会涉及到多个被叫终端,而该被叫终端的数量可以根据用户的需要和实际情况进行相应的设置,可以使多个也可以是一个。It should be noted that, in this embodiment, the third called terminal is in a normal state as an example. If the third called terminal is also in a call abnormal state, the voice gateway forwards the second incoming call. To the fourth called terminal, if the fourth called terminal is in a normal call state, implementing the fourth called terminal and the calling terminal The call connection is similar to the call connection between the third called terminal and the calling terminal; that is, in the process of implementing the call transfer by the voice gateway, during the process in which the calling terminal and the available terminal implement a call, the process of selecting an available terminal is A plurality of called terminals are involved, and the number of the called terminals can be set correspondingly according to the needs and actual conditions of the user, and multiple or one of them can be one.

下面结合本发明的可选实施例对本发明进行举例说明。The invention is exemplified below in conjunction with alternative embodiments of the invention.
本可选实施例以家庭语音网关为例进行举例说明,本可选实施例提供了一种基于家庭语音网关的呼叫转移装置,该装置包括呼叫转移配置模块,设置为配置是否开启所要呼叫转移的电话号码、转移呼叫的条件、所要播放的提示音等;The present embodiment is described by taking a home voice gateway as an example. The optional embodiment provides a home voice gateway-based call forwarding device, where the device includes a call forwarding configuration module, and is configured to configure whether to enable the call forwarding. Phone number, conditions for transferring the call, prompts to be played, etc.;
其中,当开启呼叫转移功能时,语音家庭网关有外线呼入,所接对应用户话机振铃;当所设置的呼叫转移条件满足,语音呼叫转接模块模拟摘机,停止话机振铃,并进行相关的业务处理,如拨打所配置的转接号码、当呼叫接通时的语音转接实现等。When the call forwarding function is enabled, the voice home gateway has an incoming call, and the corresponding user's phone rings; when the set call forwarding condition is satisfied, the voice call transfer module simulates off-hook, stops the phone ringing, and performs related Business processing, such as dialing the configured forwarding number, voice forwarding implementation when the call is connected, and so on.
可见,通过家庭网关FXS口所接的用户并没有真正摘机通话,并且在家庭语音网关中通过语音转接模块的处理,不会影响呼叫转移实际通话双方的语音质量,从而实现了不用软交换或IMS服务器来实现终端的呼叫转移。It can be seen that the user connected through the home gateway FXS port does not really pick up the phone, and the voice switching module in the home voice gateway does not affect the voice quality of the call forwarding actual call parties, thereby achieving no soft switching.
