具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个 或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
本申请实施例中涉及的电子设备可以是车机、车载扬声器、车载麦克风等车载设备、手机、平板电脑、桌面型、膝上型、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、手持计算机、上网本、个人数字助理(Personal Digital Assistant，PDA)、可穿戴电子设备、虚拟现实设备等。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)CDC：control domain cockpit，驾驶舱域控制器，本申请中也称其为车机。目前车机的功能除了传统的收音机、音乐视频播放、导航功能以外，已经带有蜂窝通信功能(3G，4G等)及Telematics，能结合汽车的CAN-BUS技术，实现人与车，车与外界的信息通讯，增强了用户体验及服务、安全相关的功能。
(2)主节点、从节点：在逻辑功能上区分的两类节点，分别是主节点和从节点。其中主节点管理从节点，具有分配资源的功能，负责为从节点分配资源；从节点听从主节点的调度，使用主节点分配的资源与主节点进行通信。需要注意的是，节点的属性特征可能改变，例如，当智能终端与耳机进行通信时，智能终端为主节点，耳机为从节点，但是当智能终端接入更高优先级的设备(例如CDC)，听从CDC调度的时候，此时智能终端的角色属性变更为从节点。
(3)主从通信对：包括一个主节点设备和一个从节点设备，两个设备互相连接构成一对主从通信对。
其次，为了便于理解本申请实施例，以下具体分析本申请实施例所需要解决的技术问题以及对应的应用场景。
目前智能座舱中涉及到的连接设备主要有车机(CDC)，车载音视频设备(扬声器、麦克等)、智能终端，例如手机，其他智能可穿戴设备(例如耳机)等。其中车机与车载的音视频设备主要采用有线方式连接；车机CDC与智能终端，智能终端与其他可穿戴设备大都采用无线方式进行连接，例如蓝牙。
当CDC与第一智能终端连接进行通信时，此时CDC为主节点，第一智能终端为从节点，主节点负责为从节点分配资源。此时，在座舱环境下可能存在其他智能终端(例如第二智能终端)，此时该第二智能终端可能正与智能可穿戴设备(例如，耳机)进行通信，此时第二智能终端为主节点，其连接的智能可穿戴设备为从节点，同样的，由主节点为从节点分配资源。这时，座舱内就有了两个主从通信对互不联系的独立通信。当多个不同的主从节点之间同时通信(组成不同的域)，多个主从通信对之间的通信资源可能存在冲突。当不同主从通信对之间的时频资源产生冲突，会导致严重的干扰问题，进而影响的通信、服务的性能，缺乏良好的用户体验。
因此，针对上述技术问题，本申请主要解决的问题为如何在座舱等短距离空间内，协调多个主节点间的资源分配，避免多个主从节点对之间通信的资源碰撞和干扰，保障用户体验。本申请中基于设备优先级信息实现连接建立，从而使得高优先级设备能够对于资源 的统一调度和管控，例如由CDC统一进行座舱内资源管理与分配，这种方法能够避免任何两个设备间通信对其他设备通信产生的干扰和资源碰撞。
上述方案中所出现的技术问题，以下示例性列举本申请中通信方法所应用的场景，如图1所示，图1示出了本申请实施例涉及的应用场景。该应用场景可以是在智能座舱中，可以包括高优先级主节点设备11、低优先级主节点设备12和从节点设备13。高优先级主节点设备11、低优先级主节点设备12和从节点设备13通过无线连接(例如蓝牙)的方式进行通信。其中，
高优先级主节点设备11、低优先级主节点设备12和从节点设备13均为电子设备，可以是静止的，也可以是移动的。可以是网络设备、也可以是终端设备。
网络设备包括各种形式的网络设备，例如：服务器、宏基站，微基站(也称为小站)，中继站，接入点等。其中服务器可以包括但不限于云服务器、后台服务器、组件服务器、数据处理服务器等，服务器可以通过互联网与多个终端进行通信。服务器上需要运行有相应的服务器端程序来提供相应的服务，如数据库服务、数据计算、决策执行等等。
终端设备包括通信终端、车载设备、移动设备、用户终端、移动终端、无线通信设备、便携式终端、用户代理、用户装置、服务设备或用户设备(User Equipment，UE)等计算机网络中处于网络最外围的设备，主要用于数据的输入以及处理结果的输出或显示等，也可以是安装于或运行于上述任意一个设备上的软件客户端、应用程序等。例如，终端可以是移动电话、无绳电话、智能手表、可穿戴设备、平板设备、具备无线通信功能的手持设备、计算设备、车载通信模块、智能电表或连接到无线调制解调器的其它处理设备等。
对于智能座舱这个应用场景来说，高优先级主节点设备11可以是车机CDC；低优先级主节点设备12可以是手机、平板、车载麦克风、车载扬声器等车载设备等等；从节点设备13可以是耳机、可穿戴设备等等。不同的设备之间基于设备的优先级信息实现连接建立，从而使得高优先级设备能够对于资源的统一调度和管控，有效的降低了多个主从通信对之间的相互干扰问题。
基于前述技术问题以及应用场景，本申请实施例提供了一种通信方法。将第一装置作为高优先级主节点，第二装置作为低优先级主节点，第三装置作为从节点为例。其中第三装置与第二装置建立连接成功，第二装置和第三装置为一对主从通信对。接下来使用三个具体实施例来进行详细描述，当第二装置和第三装置进入到第一装置的通信范围内时，第一装置、第二装置和第三装置如何来进行连接更新和资源分配。
实施例一、低优先级主节点(第二装置，例如手机)判断优先级，停止自身的资源分配功能，服从高优先级主节点(第一装置，例如车机)的资源分配。
具体流程描述可以参见图2。
步骤S201：获取第一装置的身份信息和优先级信息中的至少一个。
具体地，第一装置发送第一装置的身份信息和优先级信息中的至少一个，当第二装置进入到第一装置的通信范围，第二装置获取到第一装置的身份信息和优先级信息中的至少一个。其中，第一装置的身份信息指示第一装置具有资源分配功能，即第一装置可以作为 主节点。身份信息可以指示设备类型(例如车机、手机、便携式终端等)、或者是一个可以标识第一装置为主节点的身份标识。可以理解的，资源分配也可以称为资源管理或资源调度。
其中，第一装置的身份信息和优先级信息中的至少一项可以包含在第一装置发送的广播消息中(例如，系统广播消息)，也可以包含在资源控制信令(Radio Resource Control，RRC)中。或者，第一装置的身份信息和优先级信息中的至少一项可以通过广播方式发送，也可以通过单播或者组播方式发送。
或者，第一装置的身份信息和优先级信息中的至少一项可以承载在第一装置发送的物理信号中。示例性的，物理信号可以是主同步信号，不同优先级信息可以对应不同式样或图样的同步信号，其他装置可以通过接收同步信号，获取或确定第一装置的优先级信息。也可以理解为，所述优先级信息对应所述物理信号的式样或者图样，或者说，所述优先级信息通过所述物理信号的式样或者图样指示。
示例性的，身份信息可以通过设备标识码来指示，一般的，设备标识码按照一定编码规则对设备进行编码。其中设备标识码中的不同字段具有不同的含义，可以通过对部分或全部字段的解析获取设备的身份信息。例如，设备标识码中可以是有2bit用来指示设备类型，例如00标识CDC，01标识手机，10表示可穿戴设备等；又例如，身份信息也可以通过1bit来指示，即0标识主节点(具有资源分配/调度功能)，1标识从节点(只听从主节点的调度)。
可选的，身份信息可以通过媒体接入层地址(Media Access Control Address,MAC地址)来指示，与设备标识码类似，不再赘述。
可选的，优先级信息用于指示资源分配优先级。优先级低的设备要服从优先级高的设备的资源分配。或者，优先级信息可以体现为接入优先级或连接优先级，即其他装置优先与高优先级设备建立连接，或向高优先级设备发起接入，由高优先级设备统一进行资源分配。举例来说，其他装置在面对多个设备发送的连接请求时，与多个设备中优先级最高的设备建立连接；或者其他装置在向多个设备发起连接请求时，多个设备中优先级最高的设备响应该连接请求，建立连接；或者其他装置向多个设备中优先级最高的设备发起连接请求。
具体的，优先级信息可以是一个等级标识，表示了第一装置作为主节点的优先级。举例来说，CDC发送第一系统广播消息，消息中携带第一接入优先级指示000(高接入优先级)；手机发送第二系统广播消息，消息中携带第二接入优先级指示001(低接入优先级)，则此时其他装置优先向CDC发送连接建立/接入请求，由CDC为其调度资源。另外，优先级信息可以是按照协议约定的，示例性的，协议中可以约定CDC设备具有最高优先级，手机具有较低优先级等。
在一种可能的实施方式中，第二装置获取第一装置的身份信息和优先级信息中的至少一个之前，第二装置先广播发送连接请求消息。当第一装置进入到第二装置的通信范围，第一装置对第二装置发送的连接请求消息进行响应，向第二装置发送响应信息，该响应信息包括第一装置的身份信息和优先级信息中的至少一个。第二装置获取到第一装置的身份信息和优先级信息中的至少一个。
具体的，第二装置可以通过接收第一装置发送的系统广播消息来获取第一装置的身份信息和优先级信息中的至少一个。
在一种可能的实施方式中，身份信息可以指示资源分配优先级。当第二装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的资源分配优先级。装置优先向资源分配优先级较高的设备申请资源，由资源分配优先级较高的设备来统一进行资源分配和管理。
可选的，第一装置的身份信息可以为第一设备的优先级信息，即当第二装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的优先级，从而决定是否向第一装置发送连接建立请求，并由第一装置为其调度资源。
步骤S202：确定第一装置的优先级信息所指示的优先级高于第二装置的优先级。
具体地，第二装置获取第一装置的身份信息和优先级信息中的至少一个后，确定第一装置的优先级信息所指示的优先级高于第二装置的优先级。
步骤S203A：发送第一消息，设置主节点身份标识为缺省。
具体地，第二装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，设置第二装置的身份信息(指示第二装置具有资源分配功能)为缺省，即第二装置不再作为主节点为其他装置分配资源，第二装置服从第一装置的资源分配。由于第二装置与第三装置为一对主从通信对，则第二装置向第三装置发送第一消息。该第一信息用于指示第二装置不再为第三装置分配资源，即第二装置不再作为第三装置的主节点。
可选的，第一信息可以包含第一装置的身份信息和优先级信息中的至少一个，并且第一信息携带模式变更指示，指示第三装置资源获取模式的变更，根据第一信息中第一装置的身份信息和优先级信息中的至少一个，指示第三装置服从第一装置的资源分配，从第一装置获取资源分配信息。
步骤S203B：第二装置发送广播消息，广播主节点身份标识缺省。
具体地，第二装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，设置第二装置的身份信息(指示第二装置具有资源分配功能)为缺省，即第二装置不再作为主节点为其他装置分配资源，第二装置服从第一装置的资源分配。并且第二装置发送广播消息，该广播消息用于向其他设备广播声明第二装置的主节点身份标识缺省。第三装置接收到该广播消息后，不再服从第二装置的资源分配。
可选的，来自第二装置的广播消息不包含第二装置的身份信息和优先级信息，即第二装置暂时无法作为主节点与其他设备连接。
步骤S203C：第二装置停止发送广播消息。
具体地，第二装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，停止发送广播消息，第二装置服从第一装置的资源分配。第三装置在无法获取第二装置的广播消息的情况下，自动与第三装置断开连接，不再服从第二装置的资源分配。
需要注意的是，步骤S203A、S203B和S203C均为可选的步骤，且不限定执行的前后顺序。
步骤S204：第三装置与第一装置建立连接。
具体地，第三装置与第一装置建立连接，服从第一装置的资源分配，从第一装置获取 资源分配信息。
可选的，第三装置释放与第二装置的连接，释放第二装置分配的资源。
步骤S205：获取第一资源配置信息。
具体地，第二装置从第一装置获取第一资源配置信息，第一资源配置信息用于配置第二资源，第二资源用于第一装置与第二装置之间的通信；第三装置从第一装置获取第一资源配置信息，第一资源配置信息用于配置第一资源，第一资源用于第一装置与第三装置之间的通信。也即是说，第二装置和第三装置分别从第一装置直接获取资源分配信息。其中，第二装置和第三装置之间的通信数据可以通过第一装置中转而完成数据传输。
可以理解的，第二装置获取与第一资源配置信息之前还包括成功建立与第一装置的连接。
总的来说，实施例一的核心思想为，在一定范围内，只允许具有最高优先级的主节点进行主节点身份声明；低优先级主节点(第二装置)识别具有更高优先级主节点(第一装置)后，停止其资源分配功能，并通知其所连接的从节点设备(第三装置)。后续低优先级主节点和从节点均服从高优先级主节点的资源分配。
可以理解的，当从节点(第三装置)和低优先级主节点(第二装置)移出高优先级主节点(第一装置)的通信覆盖范围后，低优先级主节点(第二装置)检测不到更高优先级主节点，则其自身恢复主节点身份，第三装置继续服从第二装置资源分配。
需要说明的是，是否在通信范围可以取决于接收到的信号功率是否大于预设功率门限，当大于该预设功率门限时，则认为在通信范围内了，否则认为不在通信范围内。
可选的，是否在通信范围内也可以取决于通信速率是否大于某个速率门限，原理与信号功率类似，在此不再赘述。
实施例二、低优先级主节点(第二装置，例如手机)判断优先级，停止自身的资源分配功能，服从高优先级主节点(第一装置，例如车机)的资源分配，并且转发从节点(第三装置)的资源给第三装置。
具体流程描述可以参见图3。其中，步骤S301和步骤S302的相关描述可以参考图2中步骤S201和步骤S202。
步骤S303A：发送第一信息，指示第三装置资源获取模式的变更。
具体地，第二装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，第二装置停止自身的资源分配，服从第一装置的资源分配。由于第二装置与第三装置为一对主从通信对，则与第二装置连接的从节点(第三装置)也要服从第一装置的资源分配。则第二装置向第三装置发送第一消息。该第一信息用于指示第三装置资源获取模式的变更，即第二装置不再作为第三装置的主节点向第三装置进行资源分配，第三装置的资源不是由第二装置而分配的。
可选的，第一信息可以包含第一装置的身份信息和优先级信息中的至少一个，并且第一信息携带模式变更指示，指示第三装置资源获取模式的变更，根据第一信息中第一装置的身份信息和优先级信息中的至少一个，指示第三装置服从第一装置的资源分配，第二装置代替自己的从节点(第三装置)向第一装置申请资源，并转发给第三装置。
步骤S303B：发送广播消息，指示第三装置资源获取模式的变更。
具体地，第二装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，第二装置停止自身的资源分配，服从第一装置的资源分配。由于第二装置与第三装置为一对主从通信对，则与第二装置连接的从节点(第三装置)也要服从第一装置的资源分配。则第二装置向第三装置发送广播消息，该广播消息用于向其他设备广播声明第二装置的从节点资源获取模式的变更。第三装置接收到该广播消息后，释放第二装置之前分配的所有资源。
可选的，来自第二装置的广播消息可以包含第二装置的身份信息和优先级信息，即第二装置可以作为主节点与其他设备连接，但是需要向第一装置申请资源，并转发给从节点。
需要注意的是，步骤S303A和S303B均为可选的步骤，且不限定执行的前后顺序。
步骤S304：第三装置释放与第二装置的连接资源。
具体地，第三装置释放第二装置之前分配的所有资源，重新从第二装置获取第一装置分配的资源分配信息。
需要注意的是，步骤S304为可选的步骤。
步骤S305：获取第一资源配置信息。
具体地，第二装置从第一装置获取第一资源配置信息，第一资源配置信息用于配置第二资源，第二资源用于第一装置与第二装置之间的通信；第一资源配置信息还可以用于配置第一资源，第一资源用于第一装置与第三装置之间的通信。
可选的，第二装置向第一装置发送指示第二装置所连接的从节点的数据信息，该数据信息包括第二装置连接的从节点的数量、从节点的设备类型、从节点的身份标识信息以及从节点的数据量等等。第一装置接收到该数据信息后，为每个节点分配对应的资源，发送给第二装置。
可以理解的，第二装置获取与第一资源配置信息之前还包括成功建立与第一装置的连接。
步骤S306：发送第二资源配置信息。
具体地，第二装置接收到第一资源配置信息后，向第三装置发送第二资源配置信息。该第二资源配置信息为第一装置为第三装置分配的资源。第一资源配置信息用于配置第二资源，则第二资源配置信息配置的资源为第二资源中的部分资源。
可选的，第二装置接收到第一资源配置信息后，向第三装置转发或者透传第一资源配置信息。第一资源配置信息用于配置第一资源，第二装置直接转发第一资源配置信息(第二资源配置信息与第一资源配置信息相同)。
总的来说，实施例二的核心思想为，在一定范围内，允许具有不同优先级的主节点同时声明主节点身份；低优先级主节点(第二装置)识别具有更高优先级主节点(第一装置)后，停止其资源分配功能，并通知其所连接的从节点设备(第三装置)。后续低优先级主节点代替从节点向高优先级主节点申请资源，并发送给从节点。
可以理解的，当从节点(第三装置)和低优先级主节点(第二装置)移出高优先级主节点(第一装置)的通信覆盖范围后，低优先级主节点(第二装置)检测不到更高优先级主节点，则其自身恢复主节点身份，第三装置继续服从第二装置资源分配。
需要说明的是，是否在通信范围可以取决于接收到的信号功率是否大于预设功率门限，当大于该预设功率门限时，则认为在通信范围内了，否则认为不在通信范围内。
可选的，是否在通信范围内也可以取决于通信速率是否大于某个速率门限，原理与信号功率类似，在此不再赘述。
实施例三、从节点(第三装置)判断优先级，停止服从低优先级主节点(第二装置)资源分配，服从高优先级主节点(第一装置，例如车机)的资源分配。
具体流程描述可以参见图4：
步骤S401：获取第一装置的身份信息和优先级信息中的至少一个。
具体地，第一装置通过广播发送第一装置的身份信息和优先级信息中的至少一个，当第三装置进入到第一装置的通信范围，第三装置获取到第一装置的身份信息和优先级信息中的至少一个。其中，第一装置的身份信息指示第一装置具有资源分配功能，即第一装置可以作为主节点。身份信息可以指示设备类型(例如车机、手机、便携式终端等)、或者是一个可以标识第一装置为主节点的身份标识。可以理解的，资源分配也可以称为资源管理或资源调度。
其中，第一装置的身份信息和优先级信息中的至少一项可以包含在第一装置发送的广播消息中(例如，系统广播消息)，也可以包含在资源控制信令(Radio Resource Control，RRC)中。或者，第一装置的身份信息和优先级信息中的至少一项可以通过广播方式发送，也可以通过单播或者组播方式发送。
或者，第一装置的身份信息和优先级信息中的至少一项可以承载在第一装置发送的物理信号中。示例性的，物理信号可以是主同步信号，不同优先级信息可以对应不同式样或图样的同步信号，其他装置可以通过接收同步信号，获取或确定第一装置的优先级信息。
示例性的，身份信息可以通过设备标识码来指示，一般的，设备标识码按照一定编码规则对设备进行编码。其中设备标识码中的不同字段具有不同的含义，可以通过对部分或全部字段的解析获取设备的身份信息。例如，设备标识码中可以是有2bit用来指示设备类型，例如00标识CDC，01标识手机，10表示可穿戴设备等；又例如，身份信息也可以通过1bit来指示，即0标识主节点(具有资源分配/调度功能)，1标识从节点(只听从主节点的调度)。
可选的，身份信息可以通过媒体接入层地址(Media Access Control Address,MAC地址)来指示，与设备标识码类似，不再赘述。
可选的，优先级信息用于指示资源分配优先级。优先级低的设备要服从优先级高的设备的资源分配。或者，优先级信息也可以体现为接入优先级或连接优先级，即其他装置优先与高优先级设备建立连接，或向高优先级设备发起接入，由高优先级设备统一进行资源分配。举例来说，其他装置在面对多个设备发送的连接请求时，与多个设备中优先级最高的设备建立连接；或者其他装置在向多个设备发起连接请求时，多个设备中优先级最高的设备响应该连接请求，建立连接；或者其他装置向多个设备中优先级最高的设备发起连接请求。
具体地，优先级信息可以是一个等级标识，表示了第一装置作为主节点的优先级。举 例来说，CDC发送第一系统广播消息，消息中携带第一接入优先级指示，000(高接入优先级)；手机发送第二系统广播消息，消息中携带第二接入优先级指示001(低接入优先级)，则此时其他装置优先向CDC发送连接建立/接入请求，由CDC为其调度资源。另外，优先级信息可以是按照协议约定的，示例性的，协议中可以约定CDC设备具有最高优先级，手机具有较低优先级等。
在一种可能的实施方式中，第三装置获取第一装置的身份信息和优先级信息中的至少一个之前，第三装置先广播发送连接请求消息。当第一装置进入到第三装置的通信范围，第一装置对第三装置发送的连接请求消息进行响应，向第三装置发送响应信息，该响应信息包括第一装置的身份信息和优先级信息中的至少一个。第三装置获取到第一装置的身份信息和优先级信息中的至少一个。
具体的，第三装置可以通过接收第一装置发送的系统广播消息来获取第一装置的身份信息和优先级信息中的至少一个。
在一种可能的实施方式中，第一装置的身份信息可以指示第一装置的资源分配优先级。当第三装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的资源分配优先级。装置向资源分配优先级较高的设备申请资源，由资源分配优先级较高的设备来统一进行资源分配和管理。
可选的，第一装置的身份信息可以为第一设备的优先级信息，即当第三装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的优先级，从而决定是否向第一装置发送连接建立请求，并由第一装置为其调度资源。
步骤S402：确定第一装置的优先级信息所指示的优先级高于第二装置的优先级。
具体地，第三装置获取第一装置的身份信息和优先级信息中的至少一个后，确定第一装置的优先级信息所指示的优先级高于第二装置的优先级。
步骤S403：第三装置与第一装置建立连接。
具体地，第三装置确定第一装置的优先级信息所指示的优先级高于第二装置的优先级后，与第一装置建立连接。即第三装置服从第一装置的资源分配。
可选的，第三装置释放与第二装置的连接，即第二装置不再作为主节点为第三装置分配资源。
可选的，释放与第二装置的连接可以不需要接收第二装置的应答消息。
步骤S404：发送第二信息，指示第二资源停止资源分配。
具体地，由于第二装置与第三装置为一对主从通信对，则第二装置可以向第三装置发送第二信息。该第二信息用于指示第二装置不再为第三装置分配资源，即第二装置不再作为第三装置的主节点。
可选的，第二信息可以是中断连接请求消息。
可选的，第一信息可以包含第一装置的身份信息和优先级信息中的至少一个，指示第二装置服从第一装置的资源分配，从第一装置获取资源分配信息。
需要注意的是，步骤S404为可选的步骤。
步骤S405：获取第一资源配置信息。
具体地，第三装置从第一装置获取第一资源配置信息，第一资源配置信息用于配置第 一资源，第一资源用于第一装置与第三装置之间的通信；第二装置从第一装置获取第一资源配置信息，第一资源配置信息用于配置第二资源，第二资源用于第一装置与第二装置之间的通信。也即是说，第二装置和第三装置分别从第一装置直接获取资源分配信息。其中，第二装置和第三装置之间的通信数据可以通过第一装置中转而完成数据传输。
可以理解的，第二装置获取与第一资源配置信息之前还包括成功建立与第一装置的连接。
总的来说，实施例三的核心思想为，在一定范围内，允许具有不同优先级的主节点同时声明主节点身份；从节点(第三装置)识别具有更高优先级主节点(第一装置)后，停止服从低优先级主节点(第二装置)资源分配，并对其进行通知。后续低优先级主节点和从节点均服从高优先级主节点的资源分配。
可以理解的，当从节点(第三装置)和低优先级主节点(第二装置)移出高优先级主节点(第一装置)的通信覆盖范围后，从节点(第三装置)检测不到更高优先级主节点，则第二装置变为优先级最高的主节点，第三装置继续服从第二装置资源分配。
上述三个实施例，具体实现了连接变更和资源分配过程，基于优先级信息确定一个优先级最高的设备，对资源进行协调统一分配，避免了干扰，保障了服务质量。
接下来，以第一装置为主节点，第二装置为从节点为例，示例性的提供第一装置和第二装置的两种连接方式。
方式一、以第一装置为执行主体，第一装置主动发起连接请求，与第二装置连接。如图5所示，该方法包括但不限于如下步骤：
步骤S501：第一装置发送第三信息。
具体地，第一装置发送第三信息，该第三信息可以是通过广播、组播等方式发送。用于表明第一装置的连接请求。该第三信息中可以包含第一装置的身份信息、第一装置的优先级信息以及第一地址中的至少一个。其中，第一装置的身份信息用于表征第一装置具有资源分配的功能，身份信息具体可以是第一装置的装置类型(例如CDC、手机、便携式终端等)，也可以是其他可以表征第一装置为主节点的标识。可以理解的，资源分配也可以称为资源管理或资源调度。
可选的，第一装置可以在广播信道上，周期性广播发送第三信息；也可以通过在广播信道上随机选择资源，广播第三信息。其中，身份信息和优先级信息可以根据设备属性在出厂的时候预配置。
可选的，第一装置的身份信息和优先级信息中的至少一项可以包含在第一装置发送的广播消息中(例如，系统广播消息)，也可以包含在资源控制信令中(Radio Resource Control，RRC)。或者，第一装置的身份信息和优先级信息中的至少一项可以通过广播方式发送，也可以通过单播或者组播方式发送。
或者，第一装置的身份信息和优先级信息中的至少一项可以承载在第一装置发送的物理信号中。示例性的，物理信号可以是主同步信号，不同优先级信息可以对应不同式样或图样的同步信号，其他装置可以通过接收同步信号，获取或确定第一装置的优先级信息。
示例性的，身份信息可以通过设备标识码来指示，一般的，设备标识码按照一定编码 规则对设备进行编码。其中设备标识码中的不同字段具有不同的含义，可以通过对部分或全部字段的解析获取设备的身份信息。例如，设备标识码中可以是有2bit用来指示设备类型，例如00标识CDC，01标识手机，10表示可穿戴设备等；又例如，身份信息也可以通过1bit来指示，即0标识主节点(具有资源分配/调度功能)，1标识从节点(只听从主节点的调度)。
可选的，身份信息可以通过媒体接入层地址(Media Access Control Address,MAC地址)来指示，与设备标识码类似，不再赘述。
可选的，优先级信息用于指示资源分配优先级。优先级低的设备要服从优先级高的设备的资源分配。或者，优先级信息也可以体现为接入优先级或连接优先级，即其他装置优先与高优先级设备建立连接，或向高优先级设备发起接入，由高优先级设备统一进行资源分配。举例来说，其他装置在面对多个设备发送的连接请求时，与多个设备中优先级最高的设备建立连接；或者其他装置在向多个设备发起连接请求时，多个设备中优先级最高的设备响应该连接请求，建立连接；或者其他装置向多个设备中优先级最高的设备发起连接请求。
具体的，优先级信息可以是一个等级标识，表示了第一装置作为主节点的优先级。举例来说，CDC发送第一系统广播消息，消息中携带第一接入优先级指示，000(高接入优先级)；手机发送第二系统广播消息，消息中携带第二接入优先级指示001(低接入优先级)，则此时其他装置优先向CDC发送连接建立/接入请求，由CDC为其调度资源。另外，优先级信息可以是按照协议约定的，示例性的，协议中可以约定CDC设备具有最高优先级，手机具有较低优先级等。
在一种可能的实施方式中，第一装置的身份信息可以指示第一装置的资源分配优先级。当第二装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的资源分配优先级。装置向资源分配优先级较高的设备申请资源，由资源分配优先级较高的设备来统一进行资源分配和管理。
可选的，第一装置的身份信息可以为第一设备的优先级信息，即当第三装置获取到第一装置的身份信息时，可以通过身份信息而判断出第一装置的优先级，从而决定是否向第一装置发送连接建立请求，并由第一装置为其调度资源。
在一种可能的实施方式中，第一地址可以指示第一装置的资源分配优先级。当第二装置获取到第一装置的第一地址时，可以通过第一地址而判断出第一装置的资源分配优先级。举例来说，第一地址为CDC发送的信息；则此时通过第一地址，第二装置可以知道第一装置具有资源分配功能，且资源分配优先级最高。
可选的，第一地址为媒体接入层地址。
在一种可能的实施方式中，该第三信息中还可以包含第一装置的设备ID，第一装置的设备ID可以唯一指示第一装置，例如可以是第一装置的硬件地址；其他设备可以通过设备ID与第一装置通信。设备ID可以指示第一装置的资源分配优先级。当第二装置获取到第一装置的设备ID时，可以通过设备ID而判断出第一装置的资源分配优先级。
步骤S502：第二装置发送响应消息。
具体地，第一装置发送第三信息后，第二装置接收到该第三信息。第二装置向第一装 置发送响应消息，该响应消息包含第二装置的标识信息(例如第二装置的设备ID)。
可选的，第二装置发送响应消息的触发方式包括手动触发和自动触发。手动触发包括点击、触控、语音、手势、悬浮触控等方式。示例性的，手动触发可以是初次响应第一装置的连接建立时，第二装置接收到第一装置发送的第三信息后，根据用户的手动触发，然后发送响应消息。自动触发可以是第二装置和第一装置初次建立连接后，互相存储对方的设备ID或其他能够唯一识别对方的身份标识等；后续当第二装置再次接收到第一装置发送的第三信息时，识别到第一装置的身份标识与存储的身份标识相同，将自动根据该第三信息发送响应消息到第一装置。
步骤S503：第一装置发送连接建立信息。
具体地，第一装置接收到来自第二装置的响应消息后，向第二装置发送连接建立消息。该连接建立消息包括第二地址，该第二地址为第一装置为第二装置分配的地址，用于第一装置和第二装置之间的通信，以及第一装置为第二装置分配的资源(例如时频资源)。其中，第一装置为第二装置分配的资源可以是动态调度的资源，也可以是半静态调度的资源。
可选的，该第二地址为第一装置分配的短地址，在第一装置和第二装置通信的过程中使用第二地址可以减少信令的开销，减少数据包的长度，节约资源。根据该第二地址，可实现的方法包括，第一装置(主节点)在MAC PDU子头寻址第二装置(从节点)，并携带资源分配信息以及通信数据信息向第二装置发送。可选的，短地址也可以是物理层短地址；物理层可以根据该短地址来过滤接收到的物理层数据。
步骤S504：第二装置发送连接建立完成消息。
具体地，第二装置接收到第一装置发送的连接建立消息后，向第一装置发送连接建立完成消息，辅助第一装置(主节点)判断连接建立是否成功。第一装置接收到该连接建立完成消息，则判断与第二装置的连接建立成功。
可选的，若第一装置在预设时间之前，接收到该连接建立完成消息，则判断与第二装置的连接建立成功；若第一装置在预设时间内没有接收到该连接建立完成消息，则判断与第二装置的连接建立失败，可以重新发起新的连接。
需要注意的是，步骤S504为可选的步骤。
在图5所描述的方法中，是第一装置主动发送第三信息，得到第二装置的响应后与第二装置进行连接。与传统的连接方式不同，为了使第一装置和第二装置在进入更复杂的通信环境中能够不与其他设备产生资源冲突，本申请实施例在连接过程中，第一装置在发送的第三信息中声明其主节点身份以及主节点优先级，从节点设备(第二装置，包括耳机、可穿戴设备等)与主节点设备(第一装置)建立连接，并在连接建立后从主节点获取资源分配信息，与主节点进行数据传输。基于设备优先级信息实现连接建立，便于在主从节点接入复杂环境时，使得高优先级设备能够对于资源进行统一调度和管控，解决多个主从通信对之间的资源互相干扰问题。
方式二、以第二装置为执行主体，第二装置主动发起连接请求，与第一装置连接。如图6所示，该方法包括但不限于如下步骤：

其中，第一装置的身份信息和优先级信息中的至少一项可以包含在第一装置发送的广播消息中(例如，系统广播消息)，也可以包含在资源控制信令中(Radio Resource Control，RRC)。或者，第一装置的身份信息和优先级信息中的至少一项可以通过广播方式发送，也可以通过单播或者组播方式发送。
或者，第一装置的身份信息和优先级信息中的至少一项可以承载在第一装置发送的物理信号中。示例性的，物理信号可以是主同步信号，不同优先级信息可以对应不同式样或图样的同步信号，其他装置可以通过接收同步信号，获取或确定第一装置的优先级信息。
示例性的，身份信息可以通过设备标识码来指示，一般的，设备标识码按照一定编码规则对设备进行编码。其中设备标识码中的不同字段具有不同的含义，可以通过对部分或全部字段的解析获取设备的身份信息。例如，设备标识码中可以是有2bit用来指示设备类型，例如00标识CDC，01标识手机，10表示可穿戴设备等；又例如，身份信息也可以通过1bit来指示，即0标识主节点(具有资源分配/调度功能)，1标识从节点(只听从主节点的调度)。
可选的，身份信息可以通过媒体接入层地址(Media Access Control Address,MAC地址)来指示，与设备标识码类似，不再赘述。
可选的，优先级信息用于指示资源分配优先级。优先级低的设备要服从优先级高的设备的资源分配。或者，优先级信息也可以体现为接入优先级或连接优先级，即其他装置优先与高优先级设备建立连接，或向高优先级设备发起接入，由高优先级设备统一进行资源分配。举例来说，其他装置在面对多个设备发送的连接请求时，与多个设备中优先级最高的设备建立连接；或者其他装置在向多个设备发起连接请求时，多个设备中优先级最高的设备响应该连接请求，建立连接；或者其他装置向多个设备中优先级最高的设备发起连接请求。
具体地，优先级信息可以是一个等级标识，表示了第一装置作为主节点的优先级。举例来说，CDC发送第一系统广播消息，消息中携带第一接入优先级指示，000(高接入优先级)；手机发送第二系统广播消息，消息中携带第二接入优先级指示001(低接入优先级)，则此时其他装置优先向CDC发送连接建立/接入请求，由CDC为其调度资源。另外，优先级信息可以是按照协议约定的，示例性的，协议中可以约定CDC设备具有最高优先级，手机具有较低优先级等。
