Description

一种通信方法、通信装置及终端 技术领域
本申请涉及通信技术领域，尤其涉及短距通信技术领域，具体涉及一种通信方法、通信装置及终端。
背景技术
随着智能终端的发展，终端之间的相互发现和连接极大地丰富了人们的生活。以智能汽车为例，当用户走向车辆时，智能汽车能够自动解锁车门。在家居环境下，智能门锁、智能音响、智慧大屏等设备，让家庭生活更之智能、舒适。而通过可穿戴设备，用户可以聆听音乐、记录运动、了解身体各项指数等。总之，终端之间的通信为人们的生活提供了极大的便利。
而可供使用的终端的越来越多，多个设备之间的管理和连接也存在越来越多的挑战。例如，占用式使用的终端往往在同一时间内往往只能为另一个终端或者说一个用户提供服务。例如无线耳机只能与一个终端(例如：平板电脑)保持连接，便于为其所连接的终端提供音乐播放、接听电话等服务。
在这种情况下，当另一个终端(例如：手机)有无线耳机的使用请求时，用户需要手动断开无线耳机与平板电脑的连接，然后将无线耳机与手机进行蓝牙连接，操作的步骤复杂，用户的体验较差。
发明内容
本申请实施例公开了一种通信方法、通信装置及终端，通过本申请实施例，终端之间的连接关系可以自适应建立，提高服务质量，提升了用户的体验。

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。需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中实施例提到的“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b、或c中的至少一项(个)，可以表示：a、b、c、(a和b)、(a和c)、(b和c)、或(a和b和c)，其中a、b、c可以是单个，也可以是多个。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A、同时存在A和B、单独存在B这三种情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
以及，除非有相反的说明，本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等仅用于区别不同对象，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一消息和第二消息，只是为了区分不同的分光消息，而并不是表示这两种消息的消息结构、顺序、重要程度等的不同。
为了便于理解，以下示例地给出了部分与本申请实施例相关概念的说明以供参考。如下所示：
1.业务
业务指需要处理的事务，或者为了完成某一目标所进行的一系列活动。在某些情况下，业务也可以理解为应用或者服务。
业务可以包括多种类型，例如可以包含电话业务、音频业务、视频业务、游戏业务、网页浏览业务、日程记录及提醒等等中的一项或者多项业务。
其中，通话业务可以包括在电话、语音消息、音频通话、视频通话、游戏、语音助手等场景下，播放的语音数据，或采集用户的语音数据发送给对端等。
音频业务包括多种类型，例如可以包括媒体业务和前述通话业务中的部分业务等。其中，媒体业务可以包括为用户播放音乐、录音、视频文件中的声音、游戏中的背景音乐、来电提示音等音频业务。
2.业务的信息
业务的信息可以用于指示某一项业务，或者可以用于指示某一项业务的某一属性。可选的，业务的信息包括以下任一项或多项：
A.业务的标识(identification)
业务的标识可以是业务的名称，或者业务的编号，或者根据业务的名称(和/或编号)生成的标识业务的标识。例如，请参见表1，表1是本申请实施例提供的一种可能的业务描述信息，其中，业务的名称可以为“语音播放”、“电话接听”、视频播放业务、音频播放业务、屏幕投放业务等等。
表1业务的编号对应的业务名称
业务的编号 业务名称 优先级
0001 语音播放 2
0002 电话接听 1
0003 视频播放 3
0004 音频播放 4
0005 屏幕投放 5
B.业务的优先级
业务的优先级可以是预先配置、或者预先定义的，例如通过协议规定。业务的优先级也可以是通过管理接口设置的，例如第三方设备通过空中接口设置的优先级。业务的优先级也可以是通过用户输入指示信息确定的。
业务的优先级可以指示第一业务。例如，参见表1，一项优先级对应一种业务，优先级为1的业务则指示对应电话接听业务。当然，一项优先级也可以对应的多种业务，对于这种情况本申请同样适用。
一种可能的设计中，业务优先级可以为应用层优先级。示例性的，在应用层中，语音通话业务的优先级为1级，传统音频传输的优先级为2级，而通过预先定义的规则为等级指示数越小优先级越高(仅为示例，对于等级指示数越大优先级越高的规则同样适用)，则语音通话业务的优先级高于传统音频传输的优先级。
在又一种可能的设计中，业务优先级也可以为接入层优先级。相关的等级设置和规则可以参考前述，此处不再赘述。
C.业务的类型
一种可能的设计中，业务的类型可以通过应用层标识(applicationidentification，AID)来指示。例如，AID1用于指示电话业务；AID2用于指示传统音频业务。不同的类型可以 指示不同的优先级。
D.第一业务的服务质量(Quality of Service，QoS)需求
QoS可以用于评估服务方满足客户服务需求的能力。通过配置QoS，对企业的网络流量进行调控，避免并管理网络拥塞，减少报文的丢失率，同时也可以为企业用户提供专用带宽或者为不同的业务(语音、视频、数据等)提供差分服务。
一些可能的情况中，Qos需求可以包含通过业务优先级(Priority)、业务传输可靠性(Realibility)、业务时延(Latency)要求、业务速率(Rate)需求等中的至少一个。
示例性地，QoS需求可以指示业务的优先级。例如，若某一业务的QoS需求指示其为Best Effort业务，或者速率保障类型的业务，则相比其他QoS需求的业务具有更低的优先级。
E.第一业务的QoS类标识符(QoS Class Identifier，QCI)索引(index)
通过QCI索引可以指示业务的优先级。其中，QCI index所指示的优先级可以是预配置或者存储的终端设备上的，也可以是通过其他方式获取，或者通过计算方法确定QCI index对应的优先级。例如：语音通话业务的QCI index为15，传统音频传输QCI index为5，其中QCI index为15的业务的优先级高于QCI index为5的业务。
3.第一终端、第三终端
在一种可能的实现方式中，本申请示出的第一终端可以是手持式设备、车载设备、手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑(如笔记本电脑、掌上电脑等)、移动互联网设备(mobile internet device，MID)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的终端、智能电网(smart grid)中的终端、运输安全(transportation safety)中的终端、智慧城市(smart city)中的终端、智慧家庭(smart home)中的终端、5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。
此外，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。可选的，IoT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接、深度覆盖、终端省电。
在另一种可能的实现方式中，本申请示出的第一终端可以包括接入点(Access Point，AP)等。
可理解，对于第一终端的具体形态，本申请不作限定。但凡在有业务需求时，可以通过第二终端来处理相关业务的设备，均落入第一终端的保护范围。
可理解，对于第三终端的具体形式可以参考上述关于第一终端的描述，这里不再详述。
4.第二终端
本申请示出的第二终端可以用于处理与第一终端、第三终端或者其他终端的相关的业务。第二终端可以为可穿戴设备(例如无线耳机、手表、手环、智能眼镜等等)、音响、显示屏幕、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备等设备中的一种或者多种。
在一种可能的实现方式中，第二终端为无线耳机。该无线耳机可以有多种类型，例如可以是耳塞式、入耳式、头戴式、耳罩式或挂耳式无线耳机等。无线耳机可以包括分别佩戴于用户左耳和右耳的第一部分和第二部分。第一部分和第二部分可以通过连接线相连，例如颈带式无线耳机；第一部分和第二部分也可以是相互独立的两部分，例如真无线立体声(true wireless stereo，TWS)耳机。示例性的，当无线耳机为TWS耳机时，第一部分和第二部分可以为分别用于佩戴在用户左耳和右耳上。
5.广播、单播、组播
其中，单播(unicast)通常只有一个发送方和一个接收方，具体体现为单播时发送的数据单元的目的地址为接收方接口的地址，例如，第一节点通过单播向第二节点发送接入信息，该接入信息所在数据单元中包括第二节点的网际互连(Internet Protocol，IP)地址和/或第二节点的媒体存取控制(Media Access Control，MAC)地址。
组播(mulitcast，或者在某些场景也称为多播)方式通常为一个发送方和一组指定接收方，具体体现为组播时发送的数据单元的目的地址为组播地址(组播地址可以标识一组接口的地址，一些场景中为保留的D类地址)，发送到多播地址的数据单元被送到由该地址标识的一组接口。
广播(broadcast)通常为一个发送方和该子网内的所有接收方，广播地址(Broadcast Address)是专门用于同时向网络中所有工作站进行发送的一个地址。具体体现为广播时发送的数据单元的目的地址为广播地址，例如，在使用传输控制协议/网际协议(Transmission Control Protocol/Internet Protocol，TCP/IP)协议的网络中，主机标识段host ID为全1的IP地址为广播地址，发送到广播址的数据单元被送到host ID段所涉及的所有节点。例如，对于10.1.1.0(255.255.255.0)网段，其广播地址为10.1.1.255(255即2进制的11111111)，当发出一个目的地址为10.1.1.255的数据单元时，它将被分发给该网段上的所有节点。
上述相关概念的说明可以应用于下文的实施例中。
本申请提供一种通信方法及装置，终端之间的连接关系可以自适应建立，无需用户手动断开和连接，减少了操作流程，提高服务质量，提升了用户的体验。
本申请提供的方法可以应用于智能驾驶、智能家居、智慧城市等等领域中。网络形式可以为数据中心网络、运营商网络、园区组网、校园组网等。运营商网络可以包括一个运营商网络，或者多个不同的运营商网络等。换句话说，本申请提供的方法可以应用于任意形式的网络。
同时，本申请下文中以通信的设备为终端设备为例进行说明，但是本申请提供的方法也可以应用于其他网络设备中。该网络设备可以为任意形态的计算机、服务器、交换机(或者称为交换设备、交换芯片等)、路由器、网卡等，本申请对于该网络设备的具体形态不作限定。
示例性的，本申请提供的方法可以应用于如图1所示的通信系统，包括第一终端101和第二终端102。应理解，通信系统中还包括一个或者一个以上的其他设备，例如：还可以包含第三终端103。
其中，第一终端101、第二终端102以及第三终端为具有数据处理能力和数据收发能 力的电子设备，或者电子设备中的器件(例如：芯片或者集成电路)。
第一终端101产生第一业务(或者说生成对第一业务的处理需求)时或者之后，可以发送第一消息。其中，发送第一消息时，可以使用广播形式、组播形式或者单播形式发送，或者还可以使用其他形式发送。
在一种实现方式中，第二终端102可以接收第一消息，向第一终端101发送第二消息。该第二消息用于指示第一终端101连接第二终端102，从而使得第一终端101通过第二终端102处理第一业务。
可选的，第二终端102可以与第三终端103处于连接状态，在接收第一消息后，可以断开与第三终端103连接，从而与第一终端101建立连接。
在又一种实现方式中，第三终端103与第二终端102处于连接状态，第三终端103可以接收第一消息，向第一终端101发送第二消息。该第二消息用于指示第一终端101连接第二终端102，从而使得第一终端101通过第二终端102处理第一业务。可选的，在接收第一消息后，第三终端103可以断开与第二终端102的连接。
在上述过程中，无需用户手动的断开连接，再将第一终端101连接第二终端102，减少了操作过程。请参见图2，图2是本申请实施例提供的一种通信方法的应用场景示意图，以第一终端101为手机201、第二终端102为耳机202、第三终端103为平板203为例进行说明。耳机202可以通过无线通信技术与平板203连接，播放平板的音频。例如用户通过平板进行游戏，耳机可以播放游戏中的音频。此时，若手机201接到来电，用户需要接听语音电话时，手机201可以发送第一消息，耳机202或者平板203可以向手机发送第二消息，该第二消息用于指示手机201连接耳机202。而耳机202可以断开与平板203之间的连接，或者平板203断开与耳机202的连接关系。这样一来，手机201可以与耳机202可以建立连接关系，用户可以通过耳机202接听语音电话，而无需额外的人工操作，减少了流程，提升了终端的服务指令，提升了用户体验。
以下将详细介绍本申请提供的通信方法。
请参见图3，图3是本申请实施例提供的一种通信方法的流程示意图。可选的，该方法可以基于图1所示的架构来实现。上述方法包括但不限于如下步骤：
步骤S301：第一终端发送第一消息。其中，第一消息中包含第一终端的身份信息、第二终端的身份信息和第一业务的信息。
具体地，第一消息的发送方式可以为单播、组播或者广播。示例性地，当第一消息通过广播发送时，第一消息可以被一个子网或者一个区域内的所有节点接收。当第一消息通过组播发送时，一个通信组中的其他节点接收。当第一消息通过单播发送时(例如向第二终端发送或者向第三终端发送)，第一消息可以被第一终端指定的接收方收到。
第一终端的身份信息可以为第一终端的MAC地址、IP地址、ID(可以为固定ID也可以为临时ID)、编号、设备名称等等中的一项或者多项，或者根据上述一项或者多项信息生成的用于标识身份的信息。第二终端的身份信息可以为第二终端的MAC地址、IP地址、ID(可以为固定ID也可以为临时ID)、编号、设备名称等等中的一项或者多项，或者根据上述一项或者多项信息生成的用于标识身份的信息。
第一业务是第一终端支持的业务。例如，第一终端为手机，能够支持接听电话、视频点播、音频播放、视频聊天、游戏等等多种业务，第一业务可以属于其支持的多个业务的一个或者多个。
第一业务的信息用于指示第一业务，可以是业务的ID、优先级、类型、QoS需求、QCI索引等等中的一项或者多项，或者根据上述一项或者多项信息生成的用于标识第一业务的信息。
可选的，第一终端产生第一业务(或者说生成第一业务的处理需求)时或者之后，第一终端发送第一消息。
在一种可能的设计中，第一终端可以接收来自第二终端的发送第三消息。进一步的，第三消息可以用于指示第二终端的状态，或者用于指示第二终端当前处理的业务(为了便于描述称为第二业务。可选的，第二业务可以是与第三终端相关的业务。)，又或者用于指示第一终端连接第二终端，又或者用于指示第二终端当前连接的终端(为了便于描述称为第三终端)。
可选的，第三消息中可以包含第二终端的身份信息、第二业务的信息、第三终端的身份信息中的至少一个。本申请例举几种可能的情况：
情况一：第三消息包含第二终端的身份信息。第一终端根据第二终端的身份信息可以发现第二终端，在产生第一业务时(或者之后)，可以向第二终端发送第一消息。
情况二：第三消息包含第二业务的信息，用于指示当前处理的第二业务。第一终端根据第二业务的信息确定第一业务的优先级高于(或者等于)第二业务的优先级，从而向第二终端发送第一消息，第二终端可以暂停或者终止处理第二业务，以连接第一终端，从而处理与第一终端相关的第一业务。
可选的，第二业务可以是第三终端与所述第二终端之间处理的业务。第二终端接收第一消息后，可以断开与第三终端的连接，从而暂停、中止或者终止处理第二业务，以连接第一终端。
可选的，第一终端可以存储有业务的信息与业务的优先级的对应关系集合，因此可以根据业务的信息确定业务的优先级。进一步，该对应关系集合可以是预先定义或者配置的。
情况三：第三消息包含第三终端的身份信息。第一终端根据第三终端的身份信息，从而可以确定当前与第二终端处于连接状态的终端，从而可以向第三终端发送第一消息。相应的，第三终端根据第一消息可以获取当前第一终端对第二终端的使用需求。
在一种可能的设计中，第一终端与第二终端连接过，且连接已经断开。例如，第一终端曾经与第二终端连接(或者配对成功)，第一终端中存储有已经连接(或者已经配对成功)过的终端的身份信息，从而可以在第一消息中携带第二终端的身份信息。
例如，如图4所示，终端401可以显示已经连接(或者配对成功)过的终端。参见区域402所示，终端401与第二终端曾经连接过，终端401中可以显示第二终端的身份信息(此处以名称作为示例)。进一步的，用户可以搜索可用的设备进行连接(或者配对)、或者删除已经连接过的终端。
可选的，第一消息中还可以携带有第一终端为第二终端分配的时频资源的指示信息。
步骤S302：第一终端接收第二消息。
具体地，第二消息可以是来自第二终端，也可以是来自第二终端原本所连接的终端(第三终端)，或者还可以是控制多个终端的连接关系的控制终端。示例性地，关于第二消息地来源，本申请例举几种可能的情况：
第一种：第二消息来自第二终端。第二终端获取第一终端对第二终端的使用需求(例如：接收到来自第一终端的第一消息，或者接收其他终端的消息)，第二终端可以向第一终端发送第二消息，指示第一终端连接第二终端。
例如，第二终端接收第一消息，第一消息中包含第二终端的身份信息。响应于第一消息中的第二终端的身份信息与自身的身份信息匹配，则向第一终端发送第二消息。
再如，第二终端接收第一消息，第一消息中包含第二终端的身份信息和第一业务的信息。响应于第一消息中的第二终端的身份信息与自身的身份信息匹配，且第一业务优先级高于或者等于第二业务的优先级，则向第一终端发送第二消息。
再如，第二终端接收第一消息，第一消息中包含第二终端的身份信息和第一终端的身份信息。响应于第一消息中的第二终端的身份信息与自身的身份信息匹配，且第一终端的优先级高于当前连接的第三终端的优先级，则向第一终端发送第二消息。
可选的，第二终端发送第二消息所使用的时频资源可以是第二终端自己获取的，也可以是第一终端通过第一消息指示的时频资源。
应理解，上述第一种情况中，第二终端发送第二消息之前，可以处于与其他终端的连接状态，也可以处于空闲状态。例如，以第一终端为手机、第二终端为耳机为例，考虑一种可能的场景：手机与耳机处于可连接的范围但未建立连接，若手机需要播放音频，而手机的使用者误以为自己已经连接了耳机，在播放音频、视频时，可能会造成音量的外放、或者泄露私密的语音内容，用户的使用体验较差。而通过上述方法，手机在产生音视频播放的业务时，可以发送第一消息，耳机可以通过第二消息指示手机与其建立连接，通过耳机来处理手机的音视频业务。可以看出，在存在业务时需要耳机配合处理时，通过手机与耳机自适应的建立连接，可以提升手机、耳机的提供的服务质量，提升用户的使用体验。
第二种：第二消息来自第三终端，第三终端与第二终端处于连接状态。第三终端获取第一终端对第二终端的使用需求，第三终端可以向第一终端发送第二消息，指示第一终端连接第二终端。
第三种：在第一终端及第二终端所在网络域中存在控制终端，该控制终端可以调整多个终端的连接关系或者调度用于处理业务的终端，控制终端接收来自第一节点的第一消息，可以向第一终端发送第二消息，指示第一终端连接第二终端。
上述说明了第二消息的多种来源，以下对第二消息的具体情况进行示说明。第二消息用于指示所述第一终端与所述第二终端建立连接。其中，第二消息可以包含指示信息、第二终端的身份信息、第一终端的身份信息、第二业务的信息、第三终端的身份信息等等中的一项或者多项。示例性的，本申请例举如下几种第二消息的可能实现方式：
实现方式一：第二消息包含指示信息，该指示信息表征第二终端可以被第一终端连接。相应的，第一终端可以接收第二消息，从而与第二终端建立连接。
示例性的，该指示信息可以通过第一字段指示，该第一字段的取值为“1”则指示第一终端连接第二终端。这样一来，第一节点可以通过解析第二消息，从而确定是否连接第二 终端。进一步的，该第一字段的取值为“0”时，指示不连接第二终端。
再如，该指示信息可以指示第一业务的优先级是否高于或者等于第二业务的优先级。若第一业务的优先级高于或者等于第二业务的优先级，则指示第一终端连接第二节点。
可选的，在第二终端当前处理有多个业务时，该第二业务可以为多个业务的优先级中优先级最高的业务。
实现方式二：第二消息包含第二业务的信息，该第二业务的信息指示第二终端当前处理的第二业务。进一步的，第二业务的优先级低于或者等于第一业务的优先级，第一终端可以连接第二终端。可选的，该第二业务可以为第三终端与第二终端之间处理的业务。其中，第二业务的信息可以为第二业务的ID、优先级、类型、QoS需求、QCI索引等等中的一项或者多项，或者根据上述一项或者多项信息生成的用于标识第二业务的信息。
进一步的，第一终端可以根据第一业务的信息以及第二业务的信息，确定第二业务的优先级低于或者等于第一业务的优先级。
实现方式三：第二消息包含第二终端的身份信息。一种可能的情况中，第一终端接收到第二消息，且第二消息中包含第二终端的身份信息，则第一终端请求与第二终端进行连接。
可选的，第二消息中还可以包含安全参数。该安全参数可以用于认证第二消息的发送方的身份，或者用于认证第二终端或者第三终端的身份。
例如，以该安全参数用于认证第三终端的身份为例，安全参数可以为所述第三终端所连接的局域网的域网连接码、第三终端的用户身份信息、第二终端的身份信息、所述第一终端与所述第三终端之间的预先协商得到的参数等等。下面例举几种可能的设计：
设计1，第三终端与第二终端处于连接状态的情况下，若通过域网连接码认证第三终端与所述第一终端在同一局域网下，则第一终端可以请求与第二终端建立连接。
设计2，第三终端与第二终端处于连接状态的情况下，若第三终端与第一终端属于同一个用户，则第一终端可以请求与第二终端建立连接。
设计3，第三终端与第二终端处于连接状态的情况下，若第一终端通过预先协商得到的安全参数可以认证第三终端的身份，则第一终端可以请求与第二终端建立连接。
通过安全参数，可以使得第一终端先认证第三终端的身份，从而再根据第二消息的指示与第三终端建立连接，避免第一终端受到攻击，提高了第一终端的数据安全性。
可选的，第二消息中还可以包含连接配置信息。其中，连接配置信息可以为第二终端与第三终端连接所使用的配置信息。例如，配置信息可以包含第三终端与第二终端的之间通信的CID、时频资源的指示信息、媒体存取控制(media access control，MAC)标识(identification，ID)、物理层ID等等中的一项或者多项。
一种可能的实施情况中，CID可以用于指示第三终端与第二终端之间通信的逻辑信道或者物理信道等中的至少一个。物理层ID可以用于指示第三终端与第二终端之间通信时，用于调度第二终端的临时ID。所述时频资源指示信息可以用于指示为第一终端为第二终端配置的时频资源。
可以看出，第一终端在与第二终端建立连接时，可以通过该连接配置信息进行连接的建立，而无需再重新确定配置信息，提高了第一终端与第二终端建立连接的效率，提升了 用户的体验。
需要说明的是，第二消息可以是一条也可以是多条。示例性的，第二消息可以包含消息A和消息B。其中，消息A中包含第一终端的身份信息、第二业务的信息，消息B中包含安全参数和连接配置信息。
应理解，该第二消息也可以称为响应消息。可选的，该第二消息可以是针对第一消息的响应消息。本申请各个实施例中不对消息或者信息的名称进行限定，仅是对包含的内容进行示例性的说明和表达，其名称可以进行任意替换。
步骤S303：第一终端执行与所述第二终端的连接建立，以用于所述第一业务的处理。
具体地，第一终端与第二终端可以通过无线通信技术建立连接。例如，该无线通信技术可以是蓝牙(bluetooth，BT，具体可以是传统蓝牙或者低功耗蓝牙)、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，Wi-Fi)网络、Zigbee、调频(frequency modulation，FM)、近距离无线通信技术(near field communication，NFC)、车载短距通信技术或者其他连接技术。
在一种可能的实施情况中，第一终端向第二终端发送连接建立请求(request)，接收来自第二终端的连接响应消息，从而第二终端建立连接。可选的，连接建立请求中可以包含第一终端为第三终端分配的时频资源的指示信息。
可选的，连接建立请求中可以还包含用于协商通信密钥的参数等等中的一项或者多项。进一步可选的，响应消息中携带有第二终端确定的用于协商通信密钥的参数。第一终端与第二终端协商得到一致的通信密钥，从而配对成功，建立连接。
在又一种可能的实施情况中，第一终端可以基于所述连接配置信息向第二终端发送连接重配置消息，用于重新配置第二终端所连接的终端。
可选的，所述连接配置信息为第二终端与第三终端连接时使用的连接配置信息。
示例性地，配置信息可以包含第三终端与第二终端的之间通信的CID，第一终端通过该CID向第二终端发送连接重配置消息，从而第二终端与第一终端建可以使用该CID进行通信，而无需重新确定CID。
再如，配置信息可以包含时频资源的指示信息，第一终端通过该时频资源向第二终端发送连接重配置消息，从而第二终端与第一终端建可以使用该时频资源进行通信，而无需重新确定时频资源。
应理解，上述连接过程仅用于示例，第一终端与第二终端的连接过程中还可以包括多个阶段的认证流程和协商流程，对于包含这些流程的连接过程，本申请同样适用。
可选的，第一节点可以接收第一指示信息，所述第一指示信息用于指示确认连接所述第二终端。进一步的，该第一指示信息可以是来自用户的。例如，该第一指示信息可以是根据用户的确认操作得到的指示信息。
进一步可选的，第一终端可以输出第一提醒消息，用于提醒是否连接所述第二终端，该第一指示信息可以是对输出的第一提醒消息的确认。在接收到用户的确认操作、得到第一指示信息后，第一终端向第二终端发起连接请求。请参加图5，图5是本申请实施例提供的一种可能的界面示意图，终端501在产生第一业务之后，接收到第二消息指示连接第二终端。终端501可以输出提醒消息，如区域502所示，该提醒消息用于提醒用户存在第 二终端。接收到用户确定连接的指示信息，则执行与第二终端建立连接。
可选的，若接收到用户拒绝连接的指示信息，则不执行与第二终端建立连接。
