Description

一种发现信号与蜂窝信号的共存装置、方法及系统 技术领域
本发明涉及无线通信技术领域，尤其涉及一种发现信号与蜂窝信号的共存装置、方法及系统。
背景技术
随着终端对终端通信(Device to Device，简称：D2D)技术的发展，越来越多的终端设备具有了D2D的功能，而采用传统蜂窝通信的用户设备(User Equipment，简称：UE)使用第三代合作伙伴计划(3rd Generation Partnership Project 3GPP)、长期演进(Long Term Evolution，简称：LTE)等系统的资源直接进行终端对终端的通信，也变成一种趋势。这类UE被称为蜂窝直通终端，其资源管理是通过该UE所属蜂窝小区的基站进行的，作为发现(Discovery)资源与蜂窝资源在时域上分开，即蜂窝直通终端采用时分双工模式进行通信，其中，蜂窝直通终端使用发现资源与其他蜂窝直通终端进行发现信号的收发。蜂窝直通终端使用蜂窝资源与基站进行蜂窝信号的收发。
但是，当蜂窝直通终端进行小区切换或者资源紧张时，可能会出现基站为该终端分配的发现资源与蜂窝资源在时域上发生冲突，当存在这种冲突时，基站并不能够识别出为该终端分配的发现资源与蜂窝资源存在这样的冲突，而现有技术中蜂窝直通终端无法同时进行发送资源对应的发现信号和蜂窝资源对应的蜂窝信号的传输，从而导致该终端的D2D通信和蜂窝通信无法正常工作，从而降低了D2D通信和蜂窝通信的稳定性。

优选的，所述处理器801，具体用于在所述发现帧对应的时域资源接收其他UE发送的发现信号；或者，在所述发现帧对应的时域资源向所述其他UE发送发现信号；
还具体用于在所述寻呼帧对应的时域资源接收所述基站发送的寻呼信号；或者，在所述寻呼帧对应的时域资源向所述基站发送寻呼信号。
进一步的，本发明实施例还提供一种发现信号与蜂窝信号的共存系统，该系统包括上述实施例中所示至少一个基站和UE，其中基站可以采用上述图1、图3、图5和/或图7所示装置的结构，并实现相应的技术效果，UE可以采用上述图2、图4、图6和/或图8所示装置的结构，并实现相应的技术效果。另外该系统也可以包含数据传输过程中的其他网元，例如，网关、服务器等。
下面通过具体实施例提供一种发现信号与蜂窝信号的共存方法，以避免发送信号与蜂窝信号发生冲突，避免由于冲突导致通信稳定性降低。图9为本发明实施例提供的一种发现信号与蜂窝信号的共存方法的流程示意图，该方法的执行主体可以采用上述图1、图3、图5和/或图7所示装置的结构，并实现相应的技术效果，具体的，该装置为eNB、基站、小基站、中继设备等，如无特殊说明，下文实施例均已eNB作为示例进行说明，参照图9，该方法包括如下步骤：
步骤100、接收用户设备UE发送的通信模式请求指示；
其中，所述通信模式请求指示用于指示所述UE需要采用的通信模式；所述通信模式包括：终端对终端D2D通信或者蜂窝通信；
步骤101、根据所述通信模式请求指示，确定所述UE采用的通信模式；
步骤102、向所述UE发送确定的UE采用的通信模式的信息。
本发明实施例提供的通信模式确定方法，通过接收用户设备UE发送的 通信模式请求指示；其中，所述通信模式请求指示用于指示所述UE需要采用的通信模式；所述通信模式包括：终端对终端D2D通信或者蜂窝通信；根据所述通信模式请求指示，确定所述UE采用的通信模式；向所述UE发送确定的UE采用的通信模式的信息。从而实现了根据UE上报的通信模式请求指示，指示UE在进行发现信号的通信或蜂窝信号的通信的其中一种，从而避免UE两种通信方式发生冲突，提高了UE的D2D通信和蜂窝通信的稳定性。
在图9的基础上，图10为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，参照图10，在步骤101之前，还包括如下步骤：
步骤103、若所述UE当前进行业务的属性满足第一切换条件，则确定所述UE能够切换至所述通信模式请求指示指示的通信模式。
具体的，若所述UE当前进行业务的属性不满足第一切换条件，则说明该UE不能够切换至所述通信模式请求指示对应的通信模式。
进一步的，对于第一切换条件，其可以有多种实现形式，例如，UE现有一个语音通话(VoIP)业务正在进行，因为语音的时延要求高，所以eNB决定不让UE接收D2D通信的发现信号，于是通知UE暂缓接收发现信号，通知方法为，应答RRC信令为“延迟发现信号接收(delay discovery reception)”，又例如，一个下载业务正在进行中，时延要求低，eNB认为可以让UE接收发现信号，于是通知UE可以在邻近的下一个发现信号对应的周期内接收发现信号，通知方法为，应答RRC信令为“即刻接收发现信号(discovery reception right now)”。
显然，对于第一切换条件，还可以有其他的实现形式，只要能够保证切换后D2D通信或蜂窝通信能够正常运行即可，本实施例对于第一切换条件的具体形式不作限定。
在图9的基础上，图11为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，参照图11，在步骤101之前，还包括如下步骤：
步骤104、若所述UE当前进行业务的属性和所述预置的业务优先级满足第二切换条件，则确定所述UE能够切换至所述通信模式请求指示指示的通信模式；
具体的，若所述UE当前进行业务的属性和所述预置的业务优先级不满足第二切换条件，则说明该UE不能够切换至所述通信模式请求指示对应的通信模式。
进一步的，对于第二切换条件，其可以有多种实现形式，例如，UE签约信息：若设置发现信号为最低优先级业务时，eNB发送指示要求UE只能在非连续接收(Discontinue Receiveing，简称：DRX)的去活周期内(deactive period)内进行发现信号通信，或者没有其他业务时进行发现信号通信。若设置发现信号不是最低优先级时，则比较发现信号与其他正在进行的业务的优先级，按照从高到低来调度UE的接收，当发现信号优先级高的时候，要求UE进行发现信号的通信，即在发现信号的周期到来之后eNB不调度其他的业务数据。否则就指示给UE不能进行发现信号的通信。
可选的，当具有D2D通信功能的UE正在接收D2D发现信号(discovery)时，若UE需要建立RRC链接进行其他业务的通信。针对这种场景，下面通过具体示例进行说明：
RRC建立的过程的时间域与UE驻留的小区的发现信号接收周期相同或者有重叠的时候，要求UE暂时放弃接收发现信号，只接收基站发送的下行蜂窝信号。在RRC链接建立过程的最后一步，该条消息为“RRC连接建立完成消息(RRC connection setup complete)”，报告给eNB该UE正在进行发现信号的接收，则上文中所述上报消息即为“RRC连接建立完成消息”，进一步的，在该消息中增加一个“发现信号正在接收(discovery receiving)”指示域，例如该指示域围为“1”表示正在接收发现信号，指示域围为“0”表示没有接收发现信号。
eNB解析收到的消息，发现UE正在接收发现信号，而且UE没有能力同时下行基站发送的蜂窝信号和其他D2D UE发送的发现信号时，执行上述实施例中的步骤101、步骤102。
进一步的，对于步骤100，一种可行的实现方式为：
步骤100a、接收所述UE发送的RRC连接建立完成消息，所述RRC连接建立完成消息包含发现信号接收指示，所述发现信号接收指示用于表示所述UE正在进行所述D2D通信；
相应的，步骤101的一种可行的实现方式为：
步骤101a、根据所述发现信号接收指示，确定所述UE采用的通信模式为蜂窝通信。
可选的，当具有D2D通信功能的UE正在接收发现信号时，eNB为UE配置半静态持续调度资源(Semi-static Persistent Scheduling Resource，简称：SPS)，使得UE能够延时接收蜂窝的信号，避免发现信号与蜂窝信号发生冲突。进一步的，图12为本发明实施例提供的另一种通信模式确定方法的流程示意图，该方法的执行主体可以采用上述图1、图3、图5和/或图7所示装置的结构，并实现相应的技术效果，该方法可以和图9至图11对应的实施例结合实现，也可以独立实现，此处不予限定，具体的，参照图12，对于避免所述D2D通信的下行信号与所述蜂窝通信的下行信号冲突的情况，该方法包括如下步骤：
步骤200、若所述D2D通信的下行信号与所述蜂窝通信的下行信号在资源的时域位置上发生重合，对所述蜂窝通信的下行信号对应的子帧进行位移，使得所述D2D通信的下行信号与所述蜂窝通信的下行信号设置在所述资源的不同时域位置上；
步骤201、向所述UE发送下行信号子帧位移指示，所述下行信号子帧位移指示用于告知所述UE所述蜂窝通信的下行信号对应的子帧已发生位移，以便所述UE根据所述下行信号子帧位移指示在所述资源的不同时域位置上接收所述D2D通信的下行信号和/或所述蜂窝通信的下行信号。
图13为本发明实施例提供的另一种通信模式确定方法的流程示意图，该方法的执行主体可以采用上述图1、图3、图5和/或图7所示装置的结构，并实现相应的技术效果，该方法可以和图9至图11对应的实施例结合实现，也可以独立实现，此处不予限定，具体的，参照图13，对于避免所述D2D通信的上行信号与所述蜂窝通信的上行信号冲突的情况，该方法包括如下步骤：
步骤300、接收所述UE发送的上行信号子帧位移指示，所述上行信号子帧位移指示用于指示当所述D2D通信的上行信号与所述蜂窝通信的上行信号在资源的时域位置上发生重合时，所述UE对所述蜂窝通信的上行信号对应的子帧已进行位移，以使所述D2D通信的上行信号与所述蜂窝通信的上行信号设置在所述资源的不同时域位置上；
步骤301、根据所述上行信号子帧位移指示在所述资源的不同时域位置上接收所述D2D通信的上行信号和/或所述蜂窝通信的上行信号。
具体的，对于图12或图13对应实施例，eNB分配给UE的资源，可以周期性的使用一段时间，该资源为可配置的，或者为可更改的，即所述资源为半静态持续调度资源。
本发明实施例提供的发现信号与蜂窝信号的共存方法，通过判断所述D2D通信的信号与所述蜂窝通信的信号在资源的时域位置上是否发生重合，若发生重合，则对所述蜂窝通信的信号对应的子帧进行位移，使得所述D2D通信的信号与所述蜂窝通信的信号设置在资源的不同时域位置上。从而实现D2D通信与蜂窝通信彼此独立，避免了相互冲突，提高了D2D通信与蜂窝通信的稳定性。
进一步的，对于如何实现对所述蜂窝通信的信号对应的子帧进行位移，使得所述D2D通信的信号与所述蜂窝通信的信号相互独立。下面通过几种可行的实现方式进行举例说明：
图14至16为本发明实施例提供的子帧位移示意图，以下行信号为例，其中，D2D通信采用发现信号，蜂窝通信采用SPS信号。具体的，首先参照图14，其中，图14中上半部分为发现信号的时间轴，下半部分为SPS信号的时间轴，参见图14可见，SPS信号与发现信号重合，此时，一种可行的方式是：将SPS信号中与发现信号重合的子帧2进行位移，将该子帧2位移至下一个SPS信号对应周期内。
参照图15，上半部分为发现信号的时间轴，下半部分为SPS信号的时间轴，SPS信号与发现信号重合，此时，另一种可行的方式是：将重合的子帧2平移到下一个SPS信号对应周期的子帧3，而在下一个周期内子帧2也用于传输SPS信号。即，在一个周期内传输子帧2对应的SPS信号和子帧3对应的SPS信号。
参照图16，上半部分为发现信号的时间轴，下半部分为SPS信号的时间轴，SPS信号与发现信号重合，此时，参照图16可知，SPS信号对应的周期与发现信号对应的周期并非完全重合，例如图16中SPS信号对应的周期内，子帧8和子帧9并未与发现信号重合，因此，另一种可行的方式是，将重合的子帧2平移到同一周期内未发生重合的子帧上，例如，平移到子帧8上。
对于图14至图16所示的子帧位移的方式，其具体的实现方式为：
设D为发现信号出现的周期长度,每个周期中发现的帧号的初始位置为Dis_F，发现信号的初始子帧号为Ndoff，发现信号的持续子帧个数为Nc，SPS信号下行帧的出现的周期长度每个下行SPS信号的数据包占用时间长度为1个子帧，子帧号为Ns(子帧号的范围为0-9)。
当SFNi mod D在[Dis_F，(Dis_F*10+Ndoff+Nc)/10]内，其中SFNi为第i个系统子帧号，并且在也属于(SFNi mod(SPS DL frame cycle))时(即发现信号的子帧帧号与SPS DL子帧帧号相同时)，即如果发现信号子帧与SPS DL下行子帧相同：Nd＝SPS subframe Ns。其中Nd为发现信号的子帧号。
则eNB将Ns移位到SFNi+(Dis_F*10+Ndoff+Nc)/10+1帧的Ns子帧，同时UE也会在SFNi+(Dis_F*10+Ndoff+Nc)/10+1接收下行基站发送的信号。
可能的移位方法还有：将SPS的DL子帧变为：
发现信号的子帧最后一个子帧之后，即帧号是SFNi+(Dis_F*10+Ndoff+Nc)/10，子帧号是(Ndoff+Nc+1)mod10。
对应上文作为eNB的实施例，下面通过具体实施例对UE侧的方案进行说明。
图17为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，该方法的执行主体为具有D2D通信功能的UE，该UE可以采用上述图2、图4、图6和/或图8所示装置的结构，并实现相应的技术效果，具体的，该UE可以为手机、具有蜂窝直通功能的终端设备等，参照图17，该方法包括如下步骤：
步骤400、用户设备UE向基站发送通信模式请求指示；
其中，所述通信模式请求指示用于指示所述UE需要采用的通信模式；所述通信模式包括：终端对终端D2D通信或者蜂窝通信；
步骤401、所述UE接收所述基站发送的确定所述UE采用的通信模式的信息；
具体的，所述信息为所述基站根据所述通信模式请求指示确定得到的，所述信息对应所述基站确定所述UE采用的通信模式；
步骤402、所述UE采用所述信息对应的通信模式进行通信。
本发明实施例提供的发现信号与蜂窝信号的共存方法，通过用户设备UE向基站发送通信模式请求指示；其中，所述通信模式请求指示用于指示所述UE需要采用的通信模式；所述通信模式包括：终端对终端D2D通信或者蜂窝通信；所述UE接收所述基站发送的确定所述UE采用的通信模式的信息，所述信息为所述基站根据所述通信模式请求指示确定得到的，所述信息对应所述基站确定所述UE采用的通信模式；所述UE采用所述信息对应的通信模式进行通信。从而实现UE进行发现信号的通信或蜂窝信号的通信的其中一种，从而避免UE两种通信方式发生冲突，提高了UE的D2D通信和蜂窝通信的稳定性。
在图17的基础上，图18为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，在步骤400之前，还包括如下步骤：
步骤403、所述UE更新通信状态信息，所述通信状态信息用于表示所述UE需要采用的通信模式。
具体的，对于步骤403，其一种可行的实现方式为：UE的RAN层(具体的说是RRC层)收到了临近服务层(Prose layer)的一个开始接收发现信号的指示信息。则进行通信状态信息的更新，即UE需要的通信状态信息为D2D通信。或者，另一种可行的实现方式为：UE的RRC层通知MAC层需要接收发现信号，MAC层报告给eNB一个媒体接入层控制单元(简称：MAC CE)内容如下表一所示：
表一
LGID Discovery Receiving Status
其中逻辑组标识(Logical Group ID，简称：LGID)表明这个MAC CE是报告发现信号接收状态的，”发现信号接收状态(discovery receiving status)”为：“发现信号接收开始(discovery reception start)”或者“发现信号接收停止(discovery reception stop)”两种。对应的，在上文步骤301中，eNB发送物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)以指示UE后续是接收发现信号还是继续接收蜂窝的下行链路信号：具体如下：PDCCH上携带一个指示，指示比特为允许接收或者延迟接收。
步骤400一种可行的实现方式为：
步骤400a、所述UE向所述基站发送RRC连接建立完成消息，所述RRC连接建立完成消息包含发现信号接收指示，所述发现信号接收指示用于表示所述UE正在进行所述D2D通信；
基于步骤400a，步骤401的一种可行的实现方式为：
步骤401a、所述UE接收所述基站发送的确定所述UE采用的通信模式的信息，所述信息对应蜂窝通信。
例如，当UE的RRC层发现自身处于“RRC连接(RRC_connected)”的状态，则UE报告eNB“发现信号接收开始(discovery reception start)”，表明该UE后面希望能够接收发现信号。
可选的，对应上文实施例中eNB为UE配置半静态持续调度资源，相应的，对于避免所述D2D通信的下行信号与所述蜂窝通信的下行信号冲突的情况，所述UE接收所述基站发送的下行信号子帧位移指示，所述下行信号子帧位移指示用于指示当所述D2D通信的下行信号与所述蜂窝通信的下行信号在资源的时域位置上发生重合时，所述基站对所述蜂窝通信的下行信号对应的子帧已进行位移，以使所述D2D通信的下行信号与所述蜂窝通信的下行信号设置在所述资源的不同时域位置上；所述UE根据所述下行信号子帧位移指示在所述资源的不同时域位置上接收所述D2D通信的下行信号和/或所述蜂窝通信的下行信号。
对于避免所述D2D通信的上行信号与所述蜂窝通信的上行信号冲突的情况，若所述D2D通信的上行信号与所述蜂窝通信的上行信号在资源的时域位置上发生重合，所述UE对所述蜂窝通信的上行信号对应的子帧进行位移，使得所述D2D通信的上行信号与所述蜂窝通信的上行信号设置在所述资源的不同时域位置上；所述UE向所述基站发送的上行信号子帧位移指示，所述上行信号子帧位移指示用于指示所述蜂窝通信的上行信号对应的子帧已发生位移。
其中，所述资源为半静态持续调度资源。
需要说明的是，对于在UE接收基站配置的半静态持续调度资源后，基站侧如何进行重合子帧的位移，上文实施例已进行了详细说明，此处不再赘述。
进一步的，具有D2D通信功能的UE正在接收发现信号时，UE需要接 收网络的寻呼信道来发现是否有自己的寻呼。为了避免蜂窝通信的寻呼信号与D2D通信的发现信号之间发生冲突，本发明下述实施例提供一种发现信号与蜂窝信号的共存方法，图19为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，该方法的执行主体可以为eNB，该eNB也能够执行上文图9至图11对应实施例的功能，参照图19，该方法包括如下步骤：
步骤500、判断寻呼帧对应的时域资源与发现帧对应的时域资源是否发生重合；
步骤501、若所述寻呼帧对应的时域资源与所述发现帧对应的时域资源重合，则设置所述寻呼帧对应的时域资源与所述发现帧对应的时域资源不重合；
步骤502、将所述发现帧对应的接收信息下发给用户设备UE；或者，将所述寻呼帧对应的接收信息下发给所述UE，其中，所述发现帧对应的接收信息用于指示所述UE在所述发现帧对应的时域资源仅进行发现通信，所述寻呼帧对应的接收信息用于指示所述UE在所述寻呼帧对应的时域资源仅进行寻呼通信。
本发明实施例提供的发现信号与蜂窝信号的共存方法，通过判断寻呼帧对应的时域资源与发现帧对应的时域资源是否发生重合；若所述寻呼帧对应的时域资源与所述发现帧对应的时域资源重合，则设置所述寻呼帧对应的时域资源与所述发现帧对应的时域资源不重合；将所述发现帧对应的接收信息下发给用户设备UE；或者，将所述寻呼帧对应的接收信息下发给所述UE，其中，所述发现帧对应的接收信息用于指示所述UE在所述发现帧对应的时域资源仅进行发现通信，所述寻呼帧对应的接收信息用于指示所述UE在所述寻呼帧对应的时域资源仅进行寻呼通信。从而实现UE进行发现信号的通信或寻呼信号的通信的其中一种，从而避免UE两种通信方式发生冲突，提高了UE的D2D通信和蜂窝通信的稳定性。
优选的，步骤500的一种可行的实现方式为：
步骤500a、若所述寻呼帧对应的时域资源与所述发现帧对应的时域资源重合，则确定在所述发现帧对应的时域资源仅用于进行发现通信。
具体的，UE的需要接收的寻呼信道在时间，即寻呼帧(Paging Frame， 简称PF)由如下公式进行计算得到：
SFN mod T＝(T div N)*(UE_ID mod N)
其中，T：非连续接收的周期长度；nB为：4T,2T,T,T/2,T/4,T/8,T/16,T/32；N为:min(T,nB)；子帧号计算参数Ns为:max(1,nB/T)；UE_ID为:IMSI mod 1024。
进一步的，Ns与寻呼机会子帧(Paging Occasion，简称：PO)、寻呼子帧号(i_s)的关系如下表二和表三所示：

其中，表二所示的各个参数适用于频分双工(Frequency Division Duplexing，简称：FDD)系统，表三所示的各个参数适用于时分双工(Time Division Duplexing，简称：TDD)系统。
进一步地，i_s的可以通过如下公式获得：
i_s＝floor(UE_ID/N)mod Ns
为了能够保证UE能够接收到寻呼信号和发现信号，采用上述方法能够将寻呼信号的寻呼帧与发现信号的发现帧互不重合，避免冲突，具体的，实现方式可以为：
方式一：eNB规定在寻呼帧与发现帧发生重合时，即SFN mode D＝＝(T div N)*(UE_ID mod N),其中D是发现信号的周期，则发现帧不能作为寻呼帧 帧来发送寻呼信号。这时，UE也不用接收寻呼消息。
方式二：在寻呼帧与发现帧发生重合时，eNB更新寻呼帧位置，使得寻呼帧的位置与发现帧的位置彼此独立，从而避免冲突。
对应图19所示eNB侧的方案，下面通过具体实施例对UE侧的方案进行说明。
图20为本发明实施例提供的另一种发现信号与蜂窝信号的共存方法的流程示意图，该方法的执行主体可以为UE，该UE也能够执行上文图17、图18对应实施例的功能，参照图20，该方法包括如下步骤：
步骤600、用户设备UE接收所述基站下发的所述发现帧对应的接收信息，所述发现帧对应的接收信息用于指示所述UE在所述发现帧对应的时域资源仅进行发现通信；
步骤601、所述UE在所述发现帧对应的时域资源进行所述发现通信；
步骤602、所述UE接收所述基站下发的寻呼帧对应的接收信息，所述寻呼帧对应的接收信息用于指示所述UE在所述寻呼帧对应的时域资源仅进行寻呼通信；
步骤603、所述UE在所述寻呼帧对应的时域资源进行所述寻呼通信；
需要说明的是，所述寻呼帧对应的时域资源与所述发现帧对应的时域资源不重合。并且，执行步骤600和601时，可以不执行步骤602和步骤603，反之亦然。
本发明实施例提供的发现信号与蜂窝信号的共存方法，通过用户设备UE接收所述基站下发的所述发现帧对应的接收信息，所述发现帧对应的接收信息用于指示所述UE在所述发现帧对应的时域资源仅进行发现通信；所述UE在所述发现帧对应的时域资源进行所述发现通信；或者，所述UE接收所述基站下发的寻呼帧对应的接收信息，所述寻呼帧对应的接收信息用于指示所述UE在所述寻呼帧对应的时域资源仅进行寻呼通信；所述UE在所述寻呼帧对应的时域资源进行所述寻呼通信；其中，所述寻呼帧对应的时域资源与所述发现帧对应的时域资源不重合。从而实现UE进行发现信号的通信或寻呼信号的通信的其中一种，从而避免UE两种通信方式发生冲突，提高了UE的D2D通信和蜂窝通信的稳定性。
进一步的，步骤601的一种可行的实现方式为：
步骤601a、所述UE在所述发现帧对应的时域资源接收其他UE发送的发现信号；或者，所述UE在所述发现帧对应的时域资源向所述其他UE发送发现信号。
步骤603的一种可行的实现方式为：
步骤603a、所述UE在所述寻呼帧对应的时域资源接收所述基站发送的寻呼信号；或者，所述UE在所述寻呼帧对应的时域资源向所述基站发送寻呼信号。
其中，参见上文，所述寻呼帧对应的时域资源与发现帧对应的时域资源彼此独立，因此在寻呼帧对应的时域资源进行寻呼通信，不会与发现帧冲突；或者，当所述UE在所述对应的时域资源进行发现通信时，参照上文可知，所述发现帧对应的时域资源内不允许进行寻呼通信，因此也可以避免冲突。
