技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信系统、方法及装置。
背景技术
目前车辆与终端设备(例如手机)、智能家居设备与终端设备之间的通信均需要经过服务器进行转发。以车辆与手机之间的通信为例，手机响应于用户输入的控制指令，将控制指令发送给服务器，服务器接收到来自手机的控制指令后，将该控制指令发送给车辆。特别的是，由于车辆在关闭点火开关之后会进入休眠模式，当车辆处于睡眠模式时，服务器接收到控制指令后，还需要连接运营商的短信网关(short message service-service center，SMS-SC)或语音网关，通过SMC-SC或语音网关唤醒车辆后，才能将控制指令发送至车辆。但是，通过服务器、SMS-SC或语音网关进行交互，通信系统中的网元过多，传输路径过长，导致通信时延长、可靠性低等问题，影响用户使用体验。

S301、第一终端设备获取网络设备为第一终端设备分配的第一IP地址。
在当前通信网络中，当第一终端设备和第二终端设备需要使用网络服务时，首先需要向网络进行注册，网络注册也可以称为附着。仅以第一终端设备为例，注册流程可以分为但不限于如下几种场景：初次注册到网络、当第一终端设备移动出了原来注册的区域时进行移动性注册更新、周期性注册更新、关机后重新开机、从打开飞行模式到关闭飞行模式、从没有网络覆盖的区域移动至有网络覆盖的区域等。
第一终端设备可以在初次注册到网络时，向网络侧发送网络注册请求。网络侧接收到来自第一终端设备的网络注册请求后，为第一终端设备分配IP地址，并将携带车载终端的IP地址的网络注册响应发送至第一设备。车载终端接收到来自网络侧的网络注册响应后，可以从注册响应中获取网络侧为第一终端设备分配的IP地址。
以网络侧包含基站和5G核心网为例，第一终端设备在开机后，向基站发送网络注册请求(Registration Request)，Registration Request中携带第一终端设备的标识。基站接收到来自第一终端设备的Registration Request后，将第一终端设备的第一标识发送至核心网，第一终端设备的第一标识可以采用国际移动用户识别码(international mobile subscriber identity，IMSI)、国际移动设备标识(international mobile equipment identity，IMEI)、移动设备标识码(mobile equipment identifier，MEID)等，5G核心网与第一终端设备进行认证、鉴权后，向第一终端设备发送网络注册响应(Registration Accept)，Registration Accept中携带5G核心网为第一终端设备分配的IP地址。
进一步的，网络注册请求中还可以携带IPv6地址类型参数，IPv6地址类型参数用于 指示网络侧为第一终端设备分配IPv6地址。比如，以4G通信系统为例，第一终端设备发送网络注册请求(Attach Request)给网络侧，Attach Request中可以携带IPv6地址类型参数。再比如，以5G通信系统为例，第一终端设备发送网络注册请求(Registration Request)给网络侧，Registration Request中携带IPv6地址类型参数。
网络注册过程中可能会触发一个或者多个PDU会话的建立，例如在移动性注册更新的场景下，第一终端设备有上行数据需要发送，此时在注册流程中会创建该PDU会话，因此，还可以在请求创建PDU的请求消息中携带IPv6地址类型参数。比如，仍以5G通信系统为例，第一终端设备还可以在发送网络注册请求(PDU Session Establishment Request)给网络侧时，在PDU Session Establishment Request中携带IPv6地址类型参数。

第一终端设备将第一IP地址和第一终端设备的第一标识发送至服务器时，存在但不限于以下几种可能的实现方式：
作为第一种可能的实现方式：第一终端设备可以直接将第一IP地址和第一标识发送至服务器。
作为第二种可能的实现方式：第一终端设备将第一IP地址、第一标识和第一终端设备的第一业务类型发送至服务器。
作为第三种可能的实现方式：第一终端设备将第一IP地址、第一标识和至少一个第二终端设备的第二标识发送至服务器。至少一个第二终端设备是指与第一终端设备关联的N个第二终端设备中的至少一个终端设备。N为正整数。
作为第四种可能的实现方式：第一终端设备向服务器发送指示信息，指示信息中携带将第一IP地址和第一标识。该指示信息用于触发服务器向第一终端设备返回与第一终端设备关联的第二终端设备的第二IP地址。
S303、服务器确定与第一标识存在关联关系的第二终端设备的第二标识。
作为第一种可能的情况，服务器仅接收到来自第一终端设备的第一标识和第一IP地址。示例性的，服务器根据第一映射关系，确定与第一终端设备存在关联的N个第二终端设备，第一映射关系中包含第一标识和N个第二标识之间的关联关系，N个第二标识分别用于标识N个第二终端设备。进一步的，服务器确定将第一终端设备的IP地址发送给所述N个第二终端设备。
其中，第一映射关系可以是第一终端设备与第二终端设备建立关联的过程中，服务器接收到来自第一终端设备的第一标识，以及接收到第二终端设备的第二标识后，根据第一终端设备的第一标识和第二终端设备的第二标识建立并存储的。
作为第二种可能的情况，服务器接收到来自第一终端设备的第一标识、第一IP地址和第一业务类型。示例性的，服务器根据第一映射关系，确定与第一终端设备存在关联的N个第二终端设备；根据第二映射关系，从N个第二终端设备中，筛选出至少一个第二终端设备，第二映射关系中包含至少一个第二终端设备的第二标识与至少一个第二终端设备的第二业务类型之间的关联关系，至少一个第二终端设备的第二业务类型与第一业务类型相同。其中，第二映射关系可以是服务器在第一终端设备与第二终端设备建立关联的过程中创建并存储的。
作为第三种可能的情况，服务器接收到来自第一终端设备的第一标识、第一IP地址和至少一个第二终端设备的第二标识。示例性的，服务器根据第一标识，确定将第一IP地址通知给至少一个第二终端设备，其中，第一标识与至少一个第二终端设备的第二标识之间存在关联关系。
作为第四种可能的情况，服务器接收到来自第一终端设备的指示信息，该指示信息中携带将第一IP地址和第一标识。服务器根据第一映射关系，确定与第一终端设备存在关联的N个第二终端设备，确定将第一终端设备的IP地址发送给N个第二终端设备。进一步的，服务器还可以根据指示信息，确定将存储的N个第二终端设备的第二IP地址发送至第一终端设备。
S304、服务器根据第二标识，将第一IP地址发送给第二终端设备。
S305、第二终端设备接收并存储到来自服务器的第一IP地址。
S306、第二终端设备根据第一IP地址，向第一终端设备发送第一信息。
相应的，第一终端设备接收来自第二终端设备的第一信息。
在第一终端设备和第二终端设备进行直接通信的过程中，第一终端设备的第一IP地址和第二终端设备的第二IP地址均可能发生变化。下面仅以第一终端设备为例进行说明。
作为一种可能的实现方式，第一终端设备可以在重新启动、关闭飞行模式、从无网络覆盖的区域移动至有网络覆盖的区域等情况下，重新附着到网络。第一终端设备在第一终端设备重新附着到网络的过程中，获取网络设备为第一终端设备分配的第三IP地址，第三IP地址与第一IP地址不同。
作为另一种可能的实现方式，第一终端设备在确定第一IP地址的使用时长达到第一时长时，将第一IP地址替换为第三IP地址，第三IP地址的主机地址和第一IP地址的主机地址不同，第三IP地址的主机地址和第一IP地址的网络地址相同。IP地址可以由网络地址和主机地址组成，其中，网络地址用于标识终端设备所在的网络，主机地址用于标识该网络中的终端设备。
第一终端设备在获取到第三IP地址之后，作为一种举例，第一终端设备可以通过服务器将第三IP地址通知给第二终端设备，相应的，第二终端设备通过服务器接收第一IP地址。
作为另一种举例，第一终端设备也可以根据存储的第二终端设备的第二IP地址，将第三IP地址直接发送给第二终端设备，相应的，第二终端设备直接接收来自第一终端设备的第一IP地址。
以第一终端设备为车载终端、第二终端设备为手机为例。

示例性的，车载终端与手机可以采用S302中第一终端设备与第二终端设备的关联建立方式，车载终端与手机也可以通过以下方式建立关联：若车载终端中配置有与用户进行交互的交互装置，也可以由车载终端向服务器发起与手机进行关联。示例性地，车载终端向服务器发送绑定请求，该绑定请求中携带车辆信息、车载终端的标识和用户信息。其中，用户信息和车辆信息可以是用户通过交互装置输入至车载终端中的。服务器接收到来自车载终端的绑定请求后，存储绑定请求中携带的车辆信息和用户信息。
服务器根据接收到的用户信息，向手机发送验证请求，该验证请求中携带车辆信息。手机接收到来自服务器的验证请求后，提示用户是否与车辆信息对应的车载终端进行绑定，手机响应于用户选择的确认绑定指示，向服务器发送验证响应，该验证响应表征手机确认与车载终端建立关联关系。服务器在接收到来自手机的上述验证响应后，可以向车载终端发送绑定响应，通知车载终端车辆注册完成。进一步的，验证响应中还可以携带手机的标识，服务器接收到来自手机的上述验证响应后，可以向车载终端发送携带手机的标识的绑定响应，便于后续车载终端和手机之间进行直接通信。
服务器根据接收到的用户信息，向手机发送验证请求时，作为一种举例，若接收到的用户信息为手机号和\或邮箱，则可以直接根据手机号或邮箱，向手机发送验证请求。作为另一种举例，服务器中存储有手机的用户信息和手机的标识之间的关联关系，服务器接收到用户信息后，根据手机的用户信息和手机的标识之间的关联关系，向手机发送验证请求。
示例性地，手机的用户信息和手机的标识之间的关联关系可以通过以下方式建立：手机向服务器发送用户注册请求，该用户注册请求中携带用户信息和手机的标识。服务器接收到来自手机的注册请求后，存储注册请求中携带的用户信息。比如，手机中可以安装用于与车辆进行交互的应用A，当用户购车后，用户可以在应用A的注册界面中进行注册，在注册界面输入用户信息，用户信息中包括用户名和用户密码。手机响应于用户输入注册信息的操作，向服务器发送用户注册请求，该用户注册请求中携带用户信息和手机的标识。服务器接收到来自手机的用户注册请求时，存储用户注册请求中携带的用户名、用户密码和手机的标识。
S403、手机向服务器发送手机的IP地址和手机的标识。
手机可以在初次注册到网络时，采用S301中车载终端获取网络侧为车载终端分配的 IP地址的方式，获取网络侧为手机分配的IP地址，手机的标识也可以采用IMSI、IMEI、MEID等。
一种可能的实现方式中，手机可以在与车载终端建立关联的过程中，将手机的IP地址和手机的标识发送至服务器。在另一可能的实现方式中，手机也可以在与车载终端建立关联关系的过程后，将手机的IP地址和手机的标识发送至服务器。本申请对此不作限制，在此不再赘述。
S404、服务器根据车载终端的标识和手机的标识，确定车载终端和手机之间存在关联。
服务器接收到车载终端发送的车载终端的标识和车载终端的IP地址后，服务器根据第一映射关系，确定与车载终端存在关联的终端设备为手机。服务器接收到手机发送的手机的标识和手机的IP地址后，服务器根据第一映射关系，确定与手机存在关联的终端设备为车载终端。
S405、服务器将手机的IP地址发送给车载终端。
S406、服务器将车载终端的IP地址发送给手机。
需要说明的是，本申请实施例中，对S405和S406的执行顺序不作限定，服务器也可以先执行S406，再执行S405。
S407、手机和车载终端根据车载终端的IP地址和手机的IP地址进行直接通信。
示例性的，手机根据车载终端的IP地址，向车载终端发送第一信息。以第一信息为控制指令为例，手机检测到用户输入的控制指令后，将控制指令发送至车载终端，该控制指令携带车载终端的IP地址和手机的IP地址，车载终端的IP地址作为目的IP地址，手机的IP地址作为源IP地址。比如，手机检测到用户输入的指示开启空调的控制指令1时，将车载终端的IPv6地址作为目的IP地址，手机的IPv6地址作为源IP地址，向车载终端控制指令1。
作为一种可能的实现方式，车载终端接收到来自手机的控制指令后，若车载终端所属的车辆的运行状态表征该车辆处于休眠模式，并且此时该控制指令需要唤醒车辆，则车载终端将车辆进行唤醒，在车辆被唤醒后，执行控制指令指示的操作。其中，休眠模式是指车辆的发动机熄火后，高压系统下电，车辆通过电瓶蓄电池对车载终端的通信模块进行供电。以车辆内装载的空调为例，在休眠模式下，空调的控制单元关闭，此时将无法执行目标指令。比如，车载终端接收到目的IP地址为车载终端的IPv6地址、源IP地址为手机的IPv6地址的控制指令1后，如果车载终端所属的车辆处于休眠模式，车载终端将车辆中的空调控制单元唤醒后，执行开启空调暖风的操作。
作为另一种可能的实现方式，手机在执行S407之前，即手机向车载终端发送控制指令之前，还可以向车载终端发送唤醒指令。进一步的，车载终端接收到来自终端设备的唤醒指令，对车辆进行唤醒后，接收来自手机的控制指令，并执行控制指令指示的操作。
进一步的，车载终端可以在接收到来自手机的第一信息之后，向手机发送接收响应。手机发送第一信息之后，若在第二时长内未接收到来自车载终端的接收响应，作为一种可能的实现方式，车载终端可以将第一信息、车载终端的标识发送给服务器。服务器接收到来自手机的第一信息后，根据车载终端的标识，将第一信息发送至车载终端。
作为另一种可能的实现方式，手机还可以向服务器发送地址查询请求，该地址查询请求中携带车载终端的标识。服务器根据地址查询请求中携带的车载终端的标识，以及根据手机的标识和车载终端的标识之间的关联关系，查询到存储的车载终端的IP地址，然后将 存储的车载终端的IP地址发送至手机。作为一种举例，手机获取到服务器中存储的车载终端的IP地址后，根据服务器中存储的车载终端的IP地址，再次向车载终端发送第一信息。作为另一种举例，手机获取到服务器中存储的车载终端的IP地址后，在确定服务器和手机中存储的车载终端的IP地址不同时，将服务器中存储的车载终端的IP地址作为目的地址，再次向车载终端发送第一信息。
在车载终端和手机进行直接通信的过程中，车载终端也可以根据手机的IP地址，向手机发送第二信息，比如，车载终端也可以向手机发送用于提示用户车辆电源异常的第二信息，手机接收到第二信息后，提示用户查看车辆的电池使用情况。
在车载终端和手机进行直接通信的过程中，车载终端的IP地址和手机的IP地址均可能发生变化。当车载终端的IP地址或手机的IP地址发生变化时，车载终端或手机可以将新的IP地址通知给对方。
以车载终端为例，车载终端可以通过但不限于以下两种可能的实现方式，获取新的IP地址：
第一种可能的实现方式：车载终端可以在重新启动、关闭飞行模式、从无网络覆盖的区域移动至有网络覆盖的区域等情况下，再次向网络侧发起网络注册，获取网络侧为车载终端分配的新的IP地址，车载终端将网络侧分配的新的IP地址作为与手机进行直接通信的IP地址。
例如，车载终端可以再次向网络侧发送网络注册请求AttachRequest，该网络注册请求中携带IPv6地址类型参数，网络侧根据IPv6地址类型参数，为车载终端分配新的IPv6地址，并向车载终端发送携带车载终端的新的IPv6地址的注册响应，车载终端接收到来自网络侧的注册响应后，获取新的IPv6地址。
第二种可能的实现方式：车载终端可以周期性生成新的IP地址。示例性的，车载终端获取到网络侧分配的IP地址之后，在确定车载终端的IP地址的使用时长达到第一时长时，生成新的IP地址，新的IP地址的网络地址与旧的IP地址的网络地址相同，新的IP地址的主机地址与旧的IP地址的主机地址不同。例如，车载终端在获取到网络侧分配的第一IPv6地址之后，可以在确定车载终端的IP地址的使用时长达到7天时，周期性地生成新的IPv6地址，新的IPv6地址的网络地址与旧的IPv6地址的网络地址相同，新的IPv6地址的主机地址与旧的IPv6地址的主机地址不同，通过周期变更主机地址，提升交互安全性。
在车载终端的IP地址发生变化时，车载终端可以通过以下两种可能的方式，将新的车载终端的IP地址发送给手机，使得手机可以通过新的车载终端的IP地址与车载终端进行直接通信，下文中，以新的车载终端的IP地址为地址A，旧的车载终端的IP地址为地址B为例进行说明：
第一种可能的方式，车载终端可以通过服务器将地址A发送给手机。示例性地，车载终端可以将地址A发送至服务器，服务器接收到来自车载终端的地址A时，将存储的车载终端的IP地址替换为地址A。服务器向手机发送地址更新指示，该地址更新指示中携带车载终端的标识和地址A。手机在接收到来自服务器的地址更新指示后，根据地址更新指示中携带的车载终端的标识，确定对车载终端的IP地址进行替换时，将存储的车载终端的IP地址由地址B替换为地址A。
第二种可能的方式，车载终端可以直接将地址A发送给手机。示例性地，车载终端可以将地址A作为源IP地址，将手机的IP地址作为目的IP地址，向手机发送地址更新指示， 该地址更新指示中携带车载终端的标识和地址A。这样，手机可以在接收到地址更新指示，根据该地址更新指示中携带的车载终端的标识，确定对车载终端的IP地址进行替换时，将存储的车载终端的IP地址由地址B替换为地址A。
采取以上两种可能的方式时，手机将车载终端的IP地址由地址B替换为地址A后，可以将地址A作为目的IP地址，将手机的IP地址作为源IP地址，向车载终端发送地址更新响应。车载终端在向手机发送地址更新指示后，若在设定时长内，未接收到来自手机的地址更新响应时，可以将地址A发送至服务器。服务器接收到来自车载终端的地址A时，将存储的车载终端的IP地址由地址B替换为地址A。
下面，对手机的IP地址发生变化，手机将新的IP地址通知给车载终端的过程进行说明。
手机也可以通过上述两种可能的实现方式，获取新的IP地址，在此不再赘述。下文中，以新的手机的IP地址为地址C，旧的手机的IP地址为地址D为例进行说明。
进一步的，手机可以通过以下两种可能的方式，将新的IP地址通知给车载终端：
第一种可能的方式：在手机的IP地址发送变化时，手机可以通过服务器将地址C发送给车载终端，使得车载终端可以通过地址C与手机进行直接通信。示例性地，手机可以将地址C发送至服务器，服务器接收到来自手机的地址C时，向车载终端发送地址更新指示，该地址更新指示中携带手机的标识和地址C。车载终端中存储有手机的IP地址，车载终端在接收到来自服务器的地址更新指示后，根据地址更新指示中携带的手机的标识，确定对手机的IP地址进行替换时，将存储的手机的IP地址由地址D替换为地址C。
第二种可能的方式：手机可以直接将地址C发送给车载终端。示例性地，手机可以将地址C作为源IP地址，将车载终端的IP地址作为目的IP地址，向车载终端发送地址更新指示，该地址更新指示中携带手机的标识和地址C。车载终端中存储有手机的IP地址，车载终端可以在接收到来自手机的地址更新指示后，根据该地址更新指示中携带的手机的标识，确定对手机的IP地址进行替换时，将存储的手机的IP地址由地址D替换为地址C。
采取以上两种可能的方式时，车载终端将手机的IP地址由地址D替换为地址C后，可以将地址C作为目的IP地址，将车载终端的IP地址作为源IP地址，向手机发送地址更新响应。手机在向车载终端发送地址更新指示后，若在设定时长内，未接收到来自车载终端的地址更新响应时，可以将地址C发送至服务器。服务器接收到来自手机的地址C时，将存储的手机的IP地址由地址D替换为地址C。
进一步的，车载终端可以在无法根据手机的IP地址与手机进行直接通信时，向服务器发送地址查询请求，该地址查询请求中携带车载终端的标识。服务器根据地址查询请求中携带的车载终端的标识，以及根据手机的标识和车载终端的标识之间的关联关系，查询到存储的手机的IP地址，然后将存储的手机的IP地址发送至车载终端。车载终端获取到服务器中存储的手机的IP地址后，根据服务器中存储的手机的IP地址与手机进行直接通信。
