实施例一
请参考图1，图1为本申请实施例所提供的一种无线内部通话系统的示意图；参考图1所示，该无线内部通话系统包括：
主机，用于通过专用时隙向当前频道下的分机发送控制指令以启用或禁用分机，并通过专用时隙发送语音信号，以及接收并播放当前频道下被 启用的分机发送的语音信号；分机，用于当被启用时，通过获取的通信时隙发送语音信号，接收并播放其他被启用的分机发送的语音信号以及主机通过专用时隙发送的语音信号。
具体的，主机具有管控分机的权限，其可通过当前频道下的无线帧中的专用时隙(无线帧中供主机使用的时隙)向分机发送控制指令，以启用或者禁用某个或某些分机，并且可通过专用时隙发送语音信号，以及接收并播放各被启用的分机发送的语音信号。其中，主机启用或禁用分机的方式可以为：主机上可设置多个按键，当主机上的各按键均启用时，主机启用当前频道下的各个分机，使当前频道下的各分机均可进行听说。当主机上的某个或某些按键禁用时，主机禁用对应编号的分机，使其不能听说。此外，无论主机是否通过专用时隙发送语音信号，主机均会持续通过专用时隙发送控制指令。
分机接受主机管控，当分机被启用时，若需要发送语音信号，分机可获取无线帧中空闲的通信时隙，进而通过获取的通信时隙发送语音信号，并可接收并播放当前频道下其他被启用的分机通过通信时隙发送的语音信号以及主机通过专用时隙发送的语音信号。
其中，无线内部通话系统可支持多种部署模式，包括单主机-多分机部署模式，单主机-多中继台-多分机部署模式，多主机-多中继台-多分机部署模式，单中继台-多分机部署模式，多中继台-多分机部署模式以及分机脱网部署模式。具体而言，单主机-多分机部署模式即系统内仅存在一台主机与任意数量的分机，如图1所示。单主机-多中继台-多分机部署模式即系统仅存在一台主机、且同时存在多台中继台，主机与各中继台所在频道内都存在任意数量的分机，主机与中继台之间以及各中继台之间通过IP网络相连，如图2所示。多主机-多中继台-多分机部署模式即系统内存在多台主机、多台中继台，各主机与各中继台所在频道下都存在任意数量的分机，主机与主机、主机与中继台以及中继台与中继台通过IP网络相连，如图3所示。单中继台-多分机部署模式即系统内存在一个中继台与任意数量的分机，如图4所示。多中继台-多分机部署模式即系统内存在多台中继台与任意数量的分机，各中继台通过IP网络相连，如图5所示。分机脱网部署模式即系统内存在任意数量的分机，无主机与中继台，如图6所示。
综上所述，本申请所提供的无线内部通话系统，主机可通过专用时隙向分机发送控制指令，以控制分机的状态，选择允许发送语音信号的分机，并且主机可通过专用时隙发送语音信号，被启用的分机可通过通信时隙发送语音信号，从而实现主机与分机间的灵活便捷的无线通话，节省时间，为工作人员提供方便。
实施例二
本实施例中，无线内部通话系统仅设置一个主机，且主机未启用无线中继功能，分机未进行分组。
具体而言，主机可通过专用时隙向当前频道下的分机发送控制指令，以启用或者禁用分机，以及通过专用时隙发送语音信号。分机当被启用时，若需要发送语音信号，分机可获取一个空闲的通信时隙，进而通过此通信时隙发送语音信号，以及将接收到的当前频道下的其他被启用的分机发送的语音信号以及主机发送的语音信号混音后播放。此时，由于各被启用的分机无法接收到其自身发送的语音信号，因此分机没有回音。分机当被禁用时，此时分机不具有发送语音信号的权限，也不能播放其他分机以及主机发送的语音信号。
以无线帧包括一个专用时隙与8个通信时隙为例，专用时隙标号为0，通信时隙标号为1至8。此时，系统可支持一个主机与8个分机同时进行双向通话。主机可通过专用时隙0发送控制指令以及语音信号。被启用的分机当需要发送语音信号时，可从1至8这8个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号。且可接收并播放当前频道下的其他被启用的分机通过通信时隙发送的语音信号以及主机通过专用时隙发送的语音信号。被禁用的分机则不能发送语音信号以及播放语音信号。
实施例三
本实施例中，无线内部通话系统仅设置一个主机，且主机启用无线中继功能，分机未进行分组，分机有回声。
具体而言，主机通过专用时隙发送控制指令，以启用或者禁用分机。 被启用的分机当需要发送语音信号时获取空闲的通信时隙并通过获取的通信时隙发送语音信号。主机接收各通信时隙发送的语音信号并可将自身的语音信号与接收到的分机发送的语音信号混音后，通过专用时隙发送。从而被启用的分机除可以接收并播放其他分机通过通信时隙发送的语音信号外，还接收并播放主机通过专用时隙发送的语音信号(包括分机自身发送的语音信号)，于是，此时分机有回声。
同样以无线帧包括一个专用时隙0与8个通信时隙为例，此时系统可支持一个主机与8个分机同时进行双向通话。主机可通过专用时隙0发送控制指令以及语音信号。被启用的分机当需要发送语音信号时，可从1至8这8个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号。被启用的分机还可接收并播放其他分机通过通信时隙发送的语音信号以及接收并播放主机通过专用时隙发送的主机自身的语音信号以及转发的分机的语音信号。被禁用的分机则不能发送语音信号以及播放语音信号。
实施例四
本实施例中，无线内部通话系统仅设置一个主机，且主机启用无线中继功能，分机未进行分组，分机无回声。
具体而言，主机通过专用时隙发送控制指令，以启用或者禁用分机，以及通过专用时隙发送主机的语音信号。被启用的分机当需要发送语音信号时获取空闲的通信时隙并通过获取的通信时隙发送语音信号。主机接收各通信时隙发送的语音信号，通过对应的转发时隙转发分机发送的语音信号。被启用的分机可以接收到其他分机通过通信时隙发送的语音信号、主机通过转发时隙转发的语音信号以及主机通过专用时隙发送的语音信号，并从接收到的语音信号中剔除自身发送的语音信号后将接收的其他的语音信号混音后播放。
以无线帧包括一个专用时隙与4个通信时隙以及4个转发时隙为例，专用时隙标号为0，通信时隙标号为1至4，转发时隙标号为5至8。此时，系统可支持一个主机与4个分机同时进行双向通话。主机可通过专用时隙0发送控制指令以及语音信号。被启用的分机当需要发送语音信号时，可 从1至4这4个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号。并可接收其他分机通过通信时隙发送的语音信号以及接收并播放主机通过专用时隙发送的主机自身的语音信号以及主机通过转发时隙转发的分机发送的语音信号。例如，主机通过转发时隙5对应转发的通信时隙1发送的语音信号。此时，对于同一个分机发送的语音信号，被启用的分机可接收到两次。而由于被启用的分机可将自身发送的语音信号从接收到的所有语音信号中剔除，后进行语音播放，因此分机没有回声。被禁用的分机则不能发送语音信号以及播放语音信号。
实施例五
本实施例中，无线内部通话系统仅设置一个主机，分机进行分组。
具体而言，主机通过专用时隙发送控制指令，以启用或者禁用某个或某些分组内的所有分机，以及通过专用时隙发送主机的语音信号。其中，被启用的分组内的分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号，以及可接收并播放主机发送的语音信号、分机所在分组的其他分机通过通信时隙发送的语音信号。被禁用的分组内的分机当需要发送语音信号时，也可获取空闲的通信时隙发送语音信号，并播放其所在分组内的其他分机发送的语音信号，却不允许播放主机通过专用时隙发送的语音信号。主机在接收到不同分组的分机通过通信时隙发送的语音信号后，剔除其中被禁用的分组的分机所发送的语音信号后，将剩余的语音信号混音后播放。其中，各分机发送的语音信号中携带有分机所在分组的编号，以便于识别分机所在分组。
实施例六
本实施例中，无线内部通话系统仅设置一个主机，主机未启用无线中继功能、分机进行分组、分机无回声。
具体而言，主机通过专用时隙发送控制指令，以启用或者禁用某个或某些分组内的所有分机，以及通过专用时隙发送主机的语音信号。其中，被启用的分组内的分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号，以及可接收并播放主机发送的语音信 号、分机所在分组的其他分机通过通信时隙发送的语音信号。被禁用的分组内的分机当需要发送语音信号时，也可获取空闲的通信时隙发送语音信号，并播放其所在分组内的其他分机发送的语音信号，却不允许播放主机通过专用时隙发送的语音信号。主机在接收到不同分组的分机通过通信时隙发送的语音信号后，剔除其中被禁用的分组的分机所发送的语音信号后，将剩余的语音信号混音后播放。其中，各分机发送的语音信号中携带有分机所在分组的编号，以便于识别分机所在分组。
以无线帧包括一个专用时隙与8个通信时隙为例，专用时隙标号为0，通信时隙标号为1至8，此时，系统可支持一个主机与8个分机同时进行双向通话。主机可通过专用时隙发送控制指令以及语音信号。被启用的分组的分机当需要发送语音信号时，可从1至8这8个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，以及播放主机通过专用时隙发送的语音信号。被禁用的分组内的分机，当需要发送语音信号时，可从1至8这6个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，可播放分机所在分组的其他分机通过通信时隙发送的语音信号，却不能播放主机通过专用时隙发送的主机自身的语音信号。

具体而言，主机通过专用时隙发送控制指令，以启用或者禁用某个或某些分组内的分机，以及通过专用时隙发送主机的语音信号，并将接收到的同一分组内的分机发送的语音信号混音后，通过相应的转发时隙转发混音后的同一分组内的分机发送的语音信号。其中，被启用的分组内的各分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号，以及接收并播放其所在分组内的分机通过专用时隙发送的语音信号(可选的)、主机通过专用时隙发送的语音信号以及主机通过转发时隙转发的其所在分组内的语音信号，此时分机有回声。被禁用的分组内的分机当需要发送语音信号时，可获取空闲的通信时隙发送语音信号，并 播放其所在分组内的其他分机发送的语音信号，却不允许播放主机通过专用时隙发送的主机自身的语音信号。主机接收分机通过通信时隙发送的语音信号并剔除其中被禁用的分组的分机所发送的语音信号后，将剩余的语音信号混音后播放。其中，各分机发送的语音信号中携带有分机所在分组的编号，以便于识别分机所在分组。
以无线帧包括一个专用时隙与4个通信时隙以及4个转发时隙为例，此时系统可支持一个主机与4个分机同时进行双向通话。主机可通过专用时隙0发送控制指令以及语音信号。被启用的分组的分机当需要发送语音信号时，可从1至4这4个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，并可接收并播放主机通过专用时隙发送的主机自身的语音信号以及主机通过5至8中对应的转发时隙转发的同一分组的分机发送的语音信号(包括分机自身发送的语音信号)。
实施例八
本实施例中，无线内部通话系统仅设置一个主机，且主机启用无线中继功能，分机进行分组，分机无回声。
具体而言，主机通过专用时隙发送控制指令，以启用或者禁用某个或某些分组内的分机，以及通过专用时隙发送主机的语音信号，并将接收到的分机的语音信号，通过相应的转发时隙转发分机发送的语音信号。其中，被启用的分组内的各分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号，以及接收分机通过专用时隙发送的语音信号、主机通过专用时隙发送的语音信号以及主机通过转发时隙转发的语音信号，并从接收的所有语音信号中剔除分机自身发送的语音信号后播放剩余的语音信号，故分机没有回声。被禁用的分组内的分机当需要发送语音信号时，也可以获取空闲的通信时隙发送语音信号，却不允许播放主机发送的语音信号，但可播放剔除了自身的语音信号的其所在分组的其他分机所发送的语音信号。主机在接收到分机通过通信时隙发送的语音信号后，剔除其中被禁用的分组的分机所发送的语音信号后，将剩余的语音信号混音后播放。其中，各分机发送的语音信号中携带有分机所在分组的编号，以便于识别分机所在分组。
同样以无线帧包括一个专用时隙与4个通信时隙以及4个转发时隙为例，此时，系统可支持一个主机与4个分机同时进行双向通话。主机可通过专用时隙0发送控制指令以及语音信号。被启用的分组的分机当需要发送语音信号时，可从1至4这4个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，并可接收并播放主机通过专用时隙发送的主机自身的语音信号以及主机通过5至8中对应的转发时隙转发的分机发送的语音信号(不播放分机自身发送的语音信号)。
实施例九
本实施例中，无线内部通话系统设置一个以上的主机或者一个主机与至少一个中继台，且主机未启用无线中继功能，分机未进行分组。
具体而言，所谓中继台即仅具有语音信号转发功能而不具有控制功能的设备。中继台与主机或者主机与主机之间通过IP网络连接，各主机或中继台分属不同的频道，且各主机以及中继台所在频道下的无线帧均包含一个专用时隙。主机可通过专用时隙向其所属频道下即当前频道下的分机发送控制指令以及语音信号，并可通过IP网络接收其他主机或中继台转发的其他频道下的分机发送的语音信号。进一步，主机通过IP网络接收到其他频道下的分机发送的语音信号后，通过专用时隙发送其他频道下分机发送的语音信号，使当前频道下的被启用的分机可接收其他频道下的分机发送的语音信号。另外，主机将接收到各分机包括当前频道下的分机与其他频道下的分机发送的语音信号混音后播放。此外，主机还可将其接收到的当前频道下的分机发送的语音信号混音后通过IP网络发送至其他主机或中继台。
当前频道下的分机被启用时，若需要发送语音信号，分机可获取一个空闲的通信时隙，进而通过此通信时隙发送语音信号，以及将接收到的当前频道下的其他被启用的分机发送的语音信号、主机发送的主机自身的语音信号以及主机发送的其他频道下的分机发送的语音信号混音后播放，此时，各被启用的分机无法接收到其自身发送的语音信号，因此分机没有回音。分机当被禁用时，此时分机不能发送语音信号以及播放语音信号。

当前频道下的被启用的分组中的各分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号以及接收并播放主机发送的语音信号，包括主机转发的其他频道下的同一分组内的分机的语音信号与当前频道下主机的语音信号以及其他频道下主机的语音信号。被禁用的分组内的分机当需要发送语音信号时，可以获取空闲的通信时隙发送语音信号，而不允许播放主机发送的语音信号。
同样以无线内部通话系统包括两个主机，无线帧包括一个专用时隙0与4个通信时隙、4个转发时隙为例，此时每个频道下可支持一个主机与4个分机同时进行双向通话。当前频道下，主机可通过专用时隙0发送控制指令、其自身的语音信号以及通过IP网络接收的其他频道下的主机的语音信号，以及通过转发时隙发送其他频道下的分组内分机的语音信号。当前频道下被启用的分组内的分机当需要发送语音信号时，可从1至4这4个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，以及接收并播放其他分机以及主机发送的语音信号。被禁用的分机则不能播放主机发送的语音信号。
实施例十三
本实施例中，无线内部通话系统设置一个以上的主机或者一个主机与至少一个中继台，且主机启用无线中继功能，分机进行分组，分机有回声。
具体而言，当前主机可通过专用时隙发送控制指令以及当前主机的语音信号，并可将通过IP网络接收到的其他频道下的同一分组内的分机发送的语音信号和当前频道下的同一分组的分机的语音信号混音后通过相应的转发时隙发送出去。此外，主机还可将当前频道下的分机通过通信时隙发送的同一分组内的语音信号混音后通过IP网络发送至其他主机或中继台，以进一步通过其他主机或中继台进行语音信号转发。以及主机在接收到分机的语音信号后，剔除其中被禁用的分组的分机所发送的语音信号后，将剩余的语音信号混音后播放。
当前频道下的被启用的分组内的各分机，当需要发送语音信号时可获取空闲的通信时隙并通过获取的通信时隙发送语音信号以及接收并播放主机发送的语音信号，包括主机转发其他频道的分组内分机的语音信号与当前频道下主机的语音信号以及其他频道下主机的语音信号。被禁用的分组内的分机当需要发送语音信号时，可以获取空闲的通信时隙发送语音信号，而不允许播放主机发送的语音信号。
同样以无线内部通话系统包括两个主机，无线帧包括一个专用时隙0与4个通信时隙、4个转发时隙为例，此时每个频道下可支持一个主机与4个分机同时进行双向通话。当前频道下，主机可通过专用时隙0发送控制 指令、其自身的语音信号以及通过IP网络接收的其他频道下的主机的语音信号，以及通过转发时隙发送其他频道下的分组内分机的语音信号与当前频道下同一分组内的分机的语音信号。当前频道下被启用的分组内的分机当需要发送语音信号时，可从1至4这4个通信时隙中获取一个空闲的通信时隙，并通过获取的通信时隙发送语音信号，以及接收并播放剔除了自身的语音信号的其他分机以及主机发送的语音信号。被禁用的分机则不能播放主机发送的语音信号。
实施例十四
本实施例中，无线内部通话系统设置一个以上的主机或者一个主机与至少一个中继台，且主机启用无线中继功能，分机进行分组，分机无回声。
具体而言，主机可通过专用时隙发送控制指令，以启用或禁用当前频道下的某个或某些分组，以及通过专用时隙发送主机的语音信号。此外，主机可通过IP网络接收其他主机或中继台转发的其他频道下的分组内分机发送的语音信号，并通过对应的转发时隙发送。另外，主机通过IP网络接收到其他主机发送的语音信号后，将此其他主机的语音信号通过专用时隙发送给当前频道下的分机。并且主机在接收到当前频道下的分组内的分机通过通信时隙发送的语音信号后，进一步通过相应的转发时隙发送当前频道下的分机发送的语音信号，以及依据各分机的分组情况，将同一分组的分机发送的语音信号混音后通过IP网络发送给其他主机或中继台，以及将主机自身的语音信号通过IP网络发送给其他主机或中继台。
被启用的分组的分机当需要发送语音信号时，可获取当前频道下空闲的通信时隙并通过获取的通信时隙发送语音信号，以及至少接收并播放经由专用时隙与转发时隙发送的语音信号。被禁用的分组的分机当需要发送语音信号时，可获取当前频道下空闲的通信时隙并通过获取的通信时隙发送语音信号，以及接收并播放经由转发时隙发送的语音信号中与分机自身为同一个分组的其他分机发送的语音信号，而不播放主机的语音信号。
