具体实施方式
本发明实施例提供了一种组呼方法、装置及用户设备，用以更加简单、快速地实现组呼业务。
本发明实施例提供的组呼方法，基于自组网架构下，简单、稳定，多个用户之间可以快速地搭建起自组网执行PTT业务功能。
图1为本发明实施例提供的一种自组网架构示意图。
其中包括多个UE及基站，在同一网段内，多个UE可组成一个PPT组或多个PPT组。较佳地，不同UE之间例如可以通过交换机进行无线连接，或者是通过交换机进行有线连接，或者是通过其他设备进行连接等，从而实现同一组内的PTT业务，本发明对此不作限定。需说明的是，图1中的绘图只是示意性地，可以看出图中给出的UE为手机，当然也可以是其他的设备，如电脑等，本发明对此不作限定。
在该自组网架构下，本发明实施例提出了一种组呼方法，当同一组中的UE执行PTT业务功能时，用户可按下UE上设置的PTT按键，抢占话语权，当该UE获取话语权后，即可采集媒体数据，并将该媒体数据以广播的方式发送给该UE所在组中的其他成员，其他成员接收到该UE发送的媒体数据后进行相应地处理。
下面分别从主叫UE侧及被叫UE侧对本发明实施例提供的组呼方法进行详细地阐述。
在主叫UE侧，参见图2，本发明实施例提供的一种组呼方法，包括：
S201、主叫用户设备UE确定获取话语权；
S202、所述主叫UE将媒体数据以广播的方式发送给该主叫UE所在组中的UE。
较佳地，所述主叫UE将媒体数据以广播的方式发送给该主叫UE所在组中的UE，具体是指：所述主叫UE将媒体数据以广播的方式发送给该主叫UE所在组中的除该主叫UE之外的每一UE。
较佳地，所述主叫UE确定获取话语权，具体包括：
所述主叫UE申请话语权后，在预设的时间内检测是否接收到该主叫UE所在组中的任一UE发送的媒体数据；
当所述主叫UE在预设的时间内没有接收到该主叫UE所在组中的任一UE发送的媒体数据时，所述主叫UE确定获取话语权。
较佳地，所述主叫UE申请话语权后，在预设的时间内检测是否接收到该主叫UE所在组中的任一UE发送的媒体数据，具体包括：所述主叫UE在预设的时间内以及预设的收发端口检测是否有媒体数据发出，该媒体数据可以是该主叫UE所在组中除该主叫UE之外的任一UE发送的。
其中，所述预设的收发端口例如可以为该主叫UE所在的网段中的每一UE共同约定的收发端口，该收发端口包括：音频收发端口和/或视频收发端口。例如，所述音频收发端口可以为2030，所述视频收发端口可以为2032等，可根据具体情况进行设定，本发明对此不作限定。
较佳地，所述主叫UE将媒体数据以广播的方式发送给该主叫UE所在组中的UE，具体包括：
所述主叫UE通过UDP广播报文将媒体数据以广播的方式发送给该主叫UE所在组中的UE。
较佳地，所述主叫UE以一定时间(如20ms)为间隔，采集媒体数据，当采集到媒体数据后，通过UDP广播报文将该媒体数据发送给该主叫UE所在组中的UE。
例如，主叫UE上设置的PTT按键被用户按下时，表示该主叫UE正在申请话语权。此时，主叫UE在预设的时间内检测是否接收到该主叫UE所在组中的任一UE发送的媒体数据，若所述主叫UE在预设的时间内没有接收到该主叫UE所在组中的任一UE发送的媒体数据，则所述主叫UE确定获取话语权。相应地，主叫UE会给用户相应地提示，提示用户现在可以讲话。此时，主叫UE以20ms为间隔，采集用户发出的语音信息，并将采集到的语音信息通过UDP广播报文发送给该主叫UE所在组中的除该主叫UE之外的每一UE。
可以理解，在自组网架构下，同一组UE之间进行PTT业务功能时，例如可以通过软终端实现组内成员之间的通信。所谓软终端，是针对硬终端(实际的终端设备)而言的，可以理解为是终端设备上安装的客户端软件。
较佳地，所述主叫UE通过UDP广播报文将媒体数据以广播的方式发送给该主叫UE所在组中的UE，具体包括：
所述主叫UE根据该主叫UE所在网段内的广播地址，从预设的收发端口将携带媒体数据的UDP广播报文发送给该主叫UE所在组中的UE。
所述广播地址，例如可以设为255.255.255.255，可根据UE所在的网段对广播地址进行设定，本发明对此不作限定。
具体地，当所述媒体数据为音频媒体数据时，所述主叫UE从音频收发端口将携带所述音频媒体数据的UDP广播报文发送给该主叫UE所在组中的UE；或者，
当所述媒体数据为视频媒体数据时，所述主叫UE从视频收发端口将携带所述视频媒体数据的UDP广播报文发送给该主叫UE所在组中的UE。
较佳地，所述UDP广播报文中的数据部分格式如表1所示。即UDP广播报文的数据部分包括：发送该UDP广播报文的UE所在的组的组号、传输协议、媒体类型(音频或视频)、媒体编码格式、媒体数据。其中，传输协议例如可以为实时传输协议(Real Time Protocol，RTP)或者实时传输控制协议(Real time Transport Control Protocol，RTCP)。
表1
Figure PCTCN2016089826-appb-000001
较佳地，当所述主叫UE不需要发送媒体数据给该主叫UE所在的组中的UE时，所述主叫UE释放话语权，并设置一用以表示该被叫UE无正在处理的媒体数据的标识。从而，当用户看到该标识后，就可以获知当前话语权空闲。
例如，主叫UE发送媒体数据给该主叫UE所在的组中的UE后，此时没有需要发送的媒体数据，则该主叫UE的PTT按键被用户松开，同时，用户也可从该主叫UE上看到用以表示该被叫UE无正在处理的媒体数据的标识。
以上是一组UE中的主叫UE获取话语权及发送媒体数据的过程，相应地，该组中除该主叫UE之外的其他UE需要接收该主叫UE发送的媒体数据，并对该媒体数据进行相应地处理，具体过程如下所述。
在被叫UE侧，参见图3，本发明实施例提供的一种组呼方法，包括：
S301、被叫用户设备UE获取该被叫UE所在组中的主叫UE发送的媒体数据；
S302、所述被叫UE对所述媒体数据进行处理。
需要说明的是，这里所述的被叫UE，泛指该被叫UE所在的组中的任一被叫UE。
较佳地，所述被叫UE获取该被叫UE所在组中的主叫UE发送的媒体数据，具体包括：
所述被叫UE从预设的收发端口接收用户数据报协议UDP广播报文；
当接收到的UDP广播报文中的组标识与所述被叫UE所在组的组标识一致时，所述被叫UE从所述UDP广播报文中获取主叫UE发送的媒体数据。
也就是，一组UE中的任一UE除可以接收到本组中的UE发送的UDP广播报文外，也可以接收到其他组的UE发送的UDP广播报文。这是由于，在同一网段内，可能存在多组UE，并且多组UE共用一个收发端口，因此UE从该收发端口接收UDP广播报文时，可以接收到该UE所在组中的UE发送的UDP广播报文，也可以接收到该UE所在网段内的其它组中的UE发送的UDP广播报文。因此，接收到UDP广播报文的UE需要确认在UDP广播报文中携带的组标识与自身所在组的组标识是否一致，当UE确定该UDP广播报文中携带的组标识与自身所在组的组标识一致时，该UE从该UDP广播报文中获取媒体数据并进行处理；当该UE确定该UDP广播报文中携带的组标识与自身所在组的组标识不一致时，该UE将该UDP广播报文丢弃。
该方法中所述的UDP广播报文的数据格式与上述在主叫UE侧论述的UDP广播报文的数据格式一致，具体可参见表1，在此不再赘述。
较佳地，上述收发端口包括：音频收发端口和/或视频收发端口。
较佳地，所述被叫UE对所述媒体数据进行处理，具体包括：
所述被叫UE对所述媒体数据进行解析后播放，并记录所述主叫UE的标识信息。
较佳地，这里所述的主叫UE的标识信息，例如可以为该主叫UE的IP地址。
并且，较佳地，所述被叫UE对所述媒体数据进行解析时，可根据接收到的UDP广播报文中携带的媒体编码格式对媒体数据进行解析。
较佳地，所述被叫UE获取所述主叫UE发送的媒体数据后，该方法还包括：
所述被叫UE启动一定时器，在该定时器的定时时长内接收所述主叫UE发送的媒体数据，并且在所述定时器超时后删除所述主叫UE的标识信息，并设置用以表示该被叫UE无正在处理的媒体数据的标识。
所述定时器的定时时长例如可以设定为2s，可以根据具体情况进行设定，本发明对此不作限定。
这样，当用户看到UE上的用以表示该被叫UE无正在处理的媒体数据的标识时，就可以获知当前无PTT业务处理，话语权空闲。
较佳地，当所述被叫UE在所述定时器的定时时长内接收到该被叫UE所在组中的另一UE发送的媒体数据时，所述被叫UE将所述另一UE发送的媒体数据丢弃。
也就是说，在所述定时器的定时时长内，所述被叫UE只处理同一个UE发送的媒体数据。
在主叫UE侧，参见图4，本发明实施例提供的一种组呼装置，包括：
确定单元11，用于确定获取话语权；
发送单元12，用于将媒体数据以广播的方式发送给该装置所在组中的UE。
较佳地，所述确定单元11具体用于：
申请话语权后，在预设的时间内检测是否接收到该装置所在组中的任一UE发送的媒体数据；
当在预设的时间内没有接收到该装置所在组中的任一UE发送的媒体数据时，所述确定单元11确定获取话语权。
较佳地，所述发送单元12具体用于：
通过用户数据报协议UDP广播报文将媒体数据以广播的方式发送给本装置所在组中的UE。
较佳地，所述UDP广播报文包括以下信息：
所述发送单元12所属的装置所在组的组号、传输协议、媒体类型、媒体编码格式、媒体数据。
较佳地，所述发送单元12通过用户数据报协议UDP广播报文将媒体数据以广播的方式发送给本装置所在组中的UE时，具体用于：
根据本装置所在网段内的广播地址，从预设的收发端口将携带媒体数据的UDP广播报文以广播的方式发送给该装置所在组中的UE。
较佳地，所述预设的收发端口为：音频收发端口或视频收发端口；其中，
当所述媒体数据为音频媒体数据时，所述发送单元12从音频收发端口将携带所述音频媒体数据的UDP广播报文以广播的方式发送给本装置所在组中的UE；或者，
当所述媒体数据为视频媒体数据时，所述发送单元12从视频收发端口将携带所述视频媒体数据的UDP广播报文以广播的方式发送给本装置所在组中的UE。
在被叫UE侧，参见图5，本发明实施例提供的一种组呼装置，包括：
获取单元21，用于获取该装置所在组中的主叫用户设备UE发送的媒体数据；
处理单元22，用于对所述媒体数据进行处理。
较佳地，所述获取单元21具体用于：
从预设的收发端口接收用户数据报协议UDP广播报文；
当接收到的UDP广播报文中的组标识与本装置所在组的组标识一致时，所述获取单 元21从所述UDP广播报文中获取主叫UE发送的媒体数据。
较佳地，所述UDP广播报文包括以下信息：
所述主叫UE所在组的组号、传输协议、媒体类型、媒体编码格式、媒体数据。
较佳地，所述预设的收发端口包括：音频收发端口和/或视频收发端口。
较佳地，所述处理单元22具体用于：

较佳地，所述处理单元22还用于：
当在所述定时器的定时时长内接收到该装置所在组中的另一UE发送的媒体数据时，所述处理单元将所述另一UE发送的媒体数据丢弃。
上述组呼装置，例如可以为用户设备。
本发明实施例提供的一种用户设备，包括上述在主叫UE侧的组呼装置以及在被叫UE侧的组呼装置。也就是说，该用户设备即可以作为主叫UE侧的组呼装置，也可以作为被叫UE侧的组呼装置。
