Description

通信连接建立方法及媒介设备
技术领域
本发明涉及通信领域， 尤其涉及一种通信连接建立方法及装置。 背景技术
近场通信 （英文： Near Field Communication, 縮写： NFC ) 是一种短距 离通信连接技术， 基于射频识别 （英文： Radio Frequency IDentification, 縮 写： RFID) 技术， 用户只需要通过使一个终端设备触碰 （英文： Tap) 或者 靠近另一个终端设备， 就可实现这两个终端设备之间的近距离通信， 例如直 观、 安全并且非接触式的信息交换、 支付交易等。 目前， NFC 主要工作在 13.56MHz的频率上，可以支持 106kbit/秒、 212kbit/秒、 424kbit/秒以及 848kbit/ 秒四种传输速率， 并且通信的有效范围约为 0〜20cm， 典型值是 4cm。
由于数据的传输速率较低， NFC比较适合少量数据的交互。换言之， 若 使用 NFC传输大文件， 将会出现传输速度慢， 影响用户体验的问题。 因此， NFC论坛 （英文： NFC Forum) 提出了基于 NFC的连接切换技术。
所谓基于 NFC的连接切换技术是指： 对于同时支持 NFC以及其它通信 连接的两个终端， 可以在点对点 （英文： peer-to-peer, 縮写： P2P ) 模式下 使用 NFC交换其它通信连接方式的连接配置信息， 从而能够在两个终端之 间建立其它通信连接。其中， 其它通信连接方式包括蓝牙（英文： Bluetooth, 縮写： BT) 和无线保真 （英文： Wireless Fidelity, 縮写： Wi-Fi) 等。
但是， 在设备尺寸较大或者位置相对固定的情况下， 同时支持 NFC 以 及其它通信连接的两个终端可能不方便直接触碰或者靠近。为此， NFC论坛 在连接切换技术规范 1.3 版本 （英文： Connection Handover Technical Specification Version 1.3 , 简称： CH 1.3规范）中提出， 可通过一个支持 NFC 的可移动终端 （例如手机） 作为切换媒介 （英文： Handover Mediator) , 来 辅助两个终端建立其它通信连接。
具言之，假设希望利用切换媒介辅助建立第一终端与第二终端之间的蓝 牙连接， 根据 CH 1.3规范， 切换媒介需要： 先分别触碰或者靠近第一终端 以及第二终端， 以分别获取第一终端以及第二终端的蓝牙连接配置信息； 再 将第一终端的蓝牙连接配置信息发送至第二终端， 以使得第二终端能够基于 所接收到的蓝牙连接配置信息向第一终端发起蓝牙连接初始化请求。
根据现有技术，在利用切换媒介 M基于 NFC辅助一个设备 A建立与 N (N 2) 个设备 B的通信连接的情况下， 需要切换媒介 M分别往返于设备 A与 N个设备 B之间至少 N次，具体为： 切换媒介 M碰触或靠近设备 A— 次， 切换媒介 M碰触或靠近第一设备 一次； 切换媒介 M碰触或靠近设备 A—次， 切换媒介 M碰触或靠近第二设备 一次； …切换媒介 M碰触或靠 近设备 A—次， 切换媒介 M碰触或靠近第 N设备 BN—次。 如此操作明显 费时费力， 尤其在主设备 A与目标设备 B相距较远的情况下。
此外， 根据 CH 1.3规范， 任何一个终端在发送切换媒介响应后可确保 该消息承载列表中所有承载保持一定时间 （例如 2分钟） 的可连接状态， 因 此， 很可能导致在这 2分钟内切换媒介 M前后触碰的多个设备之间的误连 接。例如， 在 2分钟的可连接状态中， 切换媒介 M碰触或靠近设备 A—次， 碰触或靠近第一设备 —次， 碰触或靠近第二设备 B2—次， 以及碰触或靠 近设备 A—次， 此时可能会造成第一设备 及第二设备 82之间的误连接。 发明内容

实施例 1
图 1示出根据本发明实施例 1的通信连接建立方法的流程图。如图 1所示， 该方法主要包括：
歩骤 Sl、媒介设备与至少三个候选设备进行第一通信连接以获取所述候 选设备的连接配置信息， 并保存所获取到的连接配置信息。
歩骤 S2、在所述媒介设备与至少三个候选设备进行第一通信连接之前或 之后或过程中， 所述媒介设备确定一个所述候选设备为主设备， 其他所述候 选设备为目标设备。 确定方式可以包括：
方式一、所述媒介设备确定最先与所述媒介设备进行所述第一通信连接 的候选设备为所述主设备；

方式四、 所述媒介设备将在与至少三个候选设备进行第一通信连接之 后， 与所述媒介设备最先进行第一通信连接的设备， 确定为所述主设备。
歩骤 S3、所述媒介设备将所述主设备的连接配置信息与每个所述目标设 备的连接配置信息进行匹配， 以使所述主设备分别与每个所述目标设备建立 第二通信连接。 所述第一通信连接包括近场通信 NFC, 所述第二通信连接包 括蓝牙连接和 /或无线保真 Wi-Fi连接。

实施例 2
图 2示出根据本发明实施例 2的通信连接建立方法的流程图。如图 2所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介；
歩骤 S102、 媒介设备 M使其上的连接配置信息列表为空， 相当于初始化 连接配置信息列表 CARRIER— CONFIG— LIST;上述歩骤 S101和 S102的顺序不 作限定，即还可以是 S102在 S101之前，也可以将两个歩骤合为一个歩骤进行； 歩骤 S103、 媒介设备 M触碰一个候选设备 D， 以向该候选设备 D发送切 换请求（英文： Handover Request), 该切换请求可包含切换媒介记录（英文： Handover Mediation Record, 縮写 "Hm")， "Hm"表示一种特殊的承载 （英 文： carrier) 类型， 用于标识该终端 M的身份为媒介设备。 然后接收该候选 设备 D反馈的切换媒介响应 （英文： Handover Mediation Response), 该切换 媒介响应可包含该候选设备 D的连接配置信息， 从而获取该候选设备 D的连 接配置信息；
歩骤 S104、媒介设备 M将所获取到的连接配置信息保存到连接配置信息 列表中；
歩骤 S105、 媒介设备 M判断是否接收到获取完成命令； 若未接收到， 则 返回执行歩骤 S103; 若接收到， 则确定候选连接配置信息收集完毕， 并继续 执行歩骤 S106; 此外， 在一种可能的实现方式中， 媒介设备 M还可在接收到 获取完成命令之后、 即在歩骤 S105判断为接收到的情况下， 提示用户所有候 选设备的连接配置信息已收集完毕， 以提醒用户选择主设备入、 即执行歩骤 S106; 歩骤 S106、 媒介设备 M接收设备选择命令， 以使媒介设备 M将设备选择 命令所选择的设备确定为主设备 A;
歩骤 S107、 媒介设备 M触碰主设备 A， 以向主设备 A发送切换请求， 然 后接收主设备 A反馈的切换媒介响应， 从而获取主设备 A的连接配置信息； 在一种可能的实现方式中， 本歩骤还可以进一歩包括： 如果连接配置信息列 表中记录有主设备 A的连接配置信息、即主设备 A曾作为候选设备 D被媒介设 备 M触碰， 则响应于接收到的设备选择命令， 媒介设备 M还可将连接配置信 息列表中主设备 A的连接配置信息忽略掉、 例如删除或者标记为不可用； 歩骤 S108、媒介设备 M将连接配置信息列表中所保存的连接配置信息与 主设备 A的连接配置信息进行匹配处理， 以得到匹配的连接配置信息；
歩骤 S109、媒介设备 M向主设备 A发送切换初始化请求（英文： Handover Initiate Request)，该切换初始化请求包含所有目标设备 B的与主设备 A的连接 配置信息相匹配的连接配置信息； 然后接收主设备 A反馈的切换初始化响应 (英文： Handover Initiate Response), 该切换初始化响应包含主设备 A针对 每个目标设备 B选定的连接配置信息；
歩骤 S110、 主设备 A基于其针对每个目标设备 B选定的连接配置信息， 分别初始化其与每个目标设备 B之间的通信连接， 包括但不限于蓝牙连接、 Wi-Fi连接。
通过媒介设备获取并保存候选设备的连接配置信息，确定一个候选设备 为主设备其他候选设备为目标设备，将主设备的连接配置信息与每个目标设 备的连接配置信息进行匹配， 以使主设备分别与每个目标设备建立第二通信 连接， 根据本实施例的通信连接建立方法明显减少了整个通信连接建立过程 中媒介设备 M需要往返于主设备与目标设备之间进行碰触的次数、 即提高了 操作简便性。
例如， 假设目标设备 B有 N个， 则媒介设备 M所需的触碰次数可以为 N+2 次， 包括： 在接收到获取完成命令之前触碰 N+l次， 以完成包括主设备 A和 N 个目标设备 B的所有候选设备 D的连接配置信息收集； 在接收到设备选择命 令之后触碰 1次， 以获取主设备 A的连接配置信息并实现主设备 A对主设备 A 与每个目标设备 B之间的通信连接的切换初始化。 甚至， 若在接收到获取完 成命令之前并未触碰主设备 A， 则所需的触碰次数可进一歩减小至 N+l次。
此外， 按照背景技术的方案， 媒介设备获取一个目标设备的连接配置信 息后，会自动将该连接配置信息与媒介设备内处于保存状态的主设备的连接 配置信息进行匹配， 并建立目标设备与主设备之间的通信连接， 但是若此时 媒介设备中保存有其他目标设备的连接配置信息， 则有可能造成两个目标设 备之间的误连接。 根据本发明实施例， 在媒介设备获取一个候选设备的连接 配置信息后不会马上做匹配处理， 而是将其保存在连接配置信息列表中， 待 确定候选设备的身份后再由主设备发起对每个目标设备的通信连接初始化， 本发明实施例有效避免了目标设备之间的误连接。
在一种可能的实现方式中， 在歩骤 S104中媒介设备 M可仅将所获取到的 特定类型的连接配置信息、例如蓝牙连接配置信息保存到连接配置信息列表 中。 并且， 在这种实现方式下， 在歩骤 S108中， 媒介设备 M只需将所保存的 蓝牙连接配置信息与主设备 A的蓝牙连接配置信息进行匹配。 在一种可能的 具体实现方式中， 若某一候选设备 D反馈的切换媒介响应中不包含所述特定 类型的连接配置信息、 例如不包含蓝牙连接配置信息， 媒介设备 M可输出告 警消息以提醒用户该候选设备 D不支持所述特定类型的连接。
在另一种可能的实现方式中， 在歩骤 S104中媒介设备 M可将所获取到的 所有类型的连接配置信息、 例如蓝牙连接配置信息和 Wi-Fi连接配置信息都 保存到连接配置信息列表中。 并且， 在这种实现方式下， 在歩骤 S108中， 媒 介设备 M将按连接类型进行匹配处理， 例如将连接配置信息列表中所保存的 蓝牙连接配置信息与主设备 A的蓝牙连接配置信息进行匹配、 将连接配置信 息列表中所保存的 Wi-Fi连接配置信息与主设备 A的 Wi-Fi连接配置信息进行 匹配； 当然， 媒介设备 M还可以针对某特定类型的连接进行优先匹配处理， 例如优先匹配连接配置信息列表中所保存的蓝牙连接配置信息与主设备 A的 蓝牙连接配置信息。
此外，歩骤 S109中所述的切换初始化请求和切换初始化响应都属于切换 初始化消息（英文： Handover Initiate Message),按照切换初始化消息的结构， 如图 3a所示， 切换初始化消息包括切换初始化记录（英文： Handover Initiate Record , 縮写： Hi记录） 及零个至多个承载配置记录 （英文： Carrier Configuration record) , 即 NFC数据交换格式 （英文： NFC Data Exchange Format, 縮写： NDEF) 记录中的连接配置信息， 其中， 切换初始化请求应 包含至少一个 NDEF记录以携带连接配置信息， 而切换初始化响应则可能仅 包含 Hi记录而不包含 NDEF记录（图中未示出）， 这主要取决于响应设备是否 接受该切换初始化请求。 Hi记录的结构如图 3b所示， Hi记录中的可选承载记 录（英文： Alternative Carrier Record, 縮写： ac)具有指向上述 NDEF记录的 承载数据指针（英文： CARRIER— DATA— REFERENCE), 以及可能存在的附 加数据指针 （英文： AUXILIARY— DATA— REFERENCE )。 现有 Hi记录中只 能包含一个设备的 ac, 每个 ac对应一种 carrier (如蓝牙或 wifi) 即每个切换初 始化请求和切换初始化响应中只能指向一个设备的连接配置信息。在一种可 能的实施方式中， 本发明实施例对 CH 1.3规范定义的切换初始化消息中的 Hi 记录进行扩展， 扩展后的 Hi记录的结构如图 3c所示， 可以包含多个设备的可 选承载记录， 用设备标识（DEVICE ID)来标记不同设备， 每个设备对应有 相应的可选承载记录， 该设备标识下的可选承载记录即可用来指向该设备的 NDEF记录中的连接配置信息。 通过分别对切换初始化请求和切换初始化响 应中的 Hi记录的结构进行扩展， 实现在一个切换初始化请求和切换初始化响 应中包括所有匹配的连接配置信息， 从而进一歩达到简化建立通信连接歩骤 的技术效果。
进一歩地， 歩骤 S109还可以包括其他情况， 例如：
情况 1、媒介设备最后触碰主设备仅 1次（即第 N+2次）， 匹配处理后， 连 续发送接收 N对切换初始化请求 /切换初始化响应，每对切换初始化请求 /切换 初始化响应中仅包含 1个目标设备的连接配置信息； 此情况不需对切换初始 化消息中的 Hi记录进行扩展；
情况 2、 媒介设备最后触碰主设备仅 1次， 匹配处理后， 连续发送接收 X ( Kx<N) 对切换初始化请求 /切换初始化响应， 而每对切换初始化请求 /切 换初始化响应中包含 y ( Ky<N)个目标设备的连接配置信息， 其中 xXy=N; 此情况需对切换初始化消息中的 Hi记录进行扩展；
情况 3、 媒介设备最后触碰主设备 n次 （1<η<Ν) ，每次触碰中发送接收 1 对切换初始化请求 /切换初始化响应， 每对切换初始化请求 /切换初始化响应 中包含 m ( Km<N) 个目标设备的连接配置信息， 其中 mXn=N; 此情况需 对切换初始化消息中的 Hi记录进行扩展；
情况 4、 媒介设备最后触碰主设备 n次 （1<η<Ν) ，每次触碰中发送接收 m ( Km<N) 对切换初始化请求 /切换初始化响应， 每对切换初始化请求 /切换 初始化响应中包含 1个目标设备的连接配置信息， 其中 mXn=N; 此情况不需 对切换初始化消息中的 Hi记录进行扩展；
情况 5、媒介设备最后触碰主设备 n次，每次触碰中发送接收 m'(0<m'<m) 对切换初始化请求 /切换初始化响应， 每对切换初始化请求 /切换初始化响应 中包含 p (1<ρ<Ν)个目标的连接配置信息， 其中 nX m' Xp=N; 此情况需对切 换初始化消息中的 Hi记录进行扩展；
情况 6、 媒介设备最后触碰主设备 N次， 每次触碰中发送接收 1对切换初 始化请求 /切换初始化响应， 每对切换初始化请求 /切换初始化响应中包含 1 个目标设备的连接配置信息； 此情况不需对切换初始化消息中的 Hi记录进行 扩展。
实施例 3
图 4示出根据本发明实施例 3的通信连接建立方法的流程图。如图 4所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介；
歩骤 S102、 媒介设备 M使其上的连接配置信息列表为空；
歩骤 S103、 媒介设备 M触碰一个候选设备 D， 以向该候选设备 D发送切 换请求， 该切换请求可包含承载类型， 然后接收该候选设备 D反馈的切换媒 介响应， 该切换媒介响应包含该候选设备 D的连接配置信息， 从而获取该候 选设备 D的连接配置信息；
歩骤 S104、媒介设备 M将所获取到的连接配置信息保存到连接配置信息 列表中；
歩骤 S105、 媒介设备 M判断是否接收到获取完成命令； 若未接收到， 则 返回执行歩骤 S103; 若接收到， 则确定候选连接配置信息收集完毕， 并继续 执行歩骤 S 107;
歩骤 S107、 媒介设备 M触碰主设备 A， 以向主设备 A发送切换请求， 然 后接收主设备 A反馈的切换媒介响应， 从而获取主设备 A的连接配置信息； 在一种可能的实现方式中， 本歩骤还可以进一歩包括： 如果连接配置信息列 表中记录有主设备 A的连接配置信息、即主设备 A曾作为候选设备 D被媒介设 备 M触碰， 则响应于接收到的设备选择命令， 媒介设备 M还可将连接配置信 息列表中主设备 A的连接配置信息忽略掉、 例如删除或者标记为不可用； 歩骤 S108、媒介设备 M将连接配置信息列表中所保存的连接配置信息与 主设备 A的连接配置信息进行匹配处理， 以得到匹配的连接配置信息；
在一种可能的实现方式中， 本歩骤还可以进一歩包括： 媒介设备 M在上 述匹配处理过程中，若匹配出其中一个候选设备的连接配置信息中的媒体访 问控制（英文： Media Access Control, 縮写： MAC)地址与本次触碰中所获 取主设备 A的连接配置信息中的 MAC地址相同， 则还可将该连接配置信息列 表中主设备 A的连接配置信息忽略掉、 例如删除或者标记为不可用；
歩骤 S109、 媒介设备 M向主设备 A发送切换初始化请求， 该切换初始化 请求包含所有目标设备 B的与主设备 A的连接配置信息相匹配的连接配置信 息； 然后接收主设备 A反馈的切换初始化响应， 该切换初始化响应包含主设 备 A针对每个目标设备 B选定的连接配置信息； 与实施例 2类似， 歩骤 S109还 可以包括其他情况， 在此不再赘述；
歩骤 S110、 主设备 A基于其针对每个目标设备 B选定的连接配置信息， 分别初始化其与每个目标设备 B之间的通信连接。
通过将图 4与图 2进行比较， 并结合以上介绍可知， 本实施例与实施例 2 的主要区别在于： 没有执行歩骤 S106, 即不使用设备选择命令， 而是直接将 在接收到获取完成命令之后， 首次触碰的设备确定为主设备 A， 从而在触碰 主设备 A时确定其主设备的身份并进行连接配置信息的获取与匹配处理。
因此， 针对实施例 2的大部分详细解释和特别说明， 例如关于连接配置 信息列表保存的连接配置信息的类型、关于连接配置信息的匹配处理以及关 于切换初始化消息的扩展等， 同样适用于本实施例， 并在此不再赘述。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以明显 提高操作简便性。例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通 信连接， 在本实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次 数可以为 N+2次， 包括： 在接收到获取完成命令之前触碰 N+1次， 以完成包 括主设备 A和 N个目标设备 B的所有候选设备 D的连接配置信息收集； 在接收 到获取完成命令之后触碰 1次，以获取主设备 A的连接配置信息并实现主设备 A对主设备 A与每个目标设备 B之间的通信连接的切换初始化。甚至， 若在接 收到获取完成命令之前并未触碰主设备 A， 则所需的触碰次数可进一歩减小 至 N+1次。 SP， 本实施例与实施例 2所需的触碰次数类似。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以避免 目标设备之间的误连接， 在此不再赘述。
在一种可能的实现方式中， 与实施例 2类似， 媒介设备 M还可在接收到 获取完成命令之后、 即在歩骤 S105判断为是的情况下， 提示用户所有候选设 备的连接配置信息已收集完毕， 以提醒用户使媒介设备 M触碰主设备 A、 即 执行歩骤 S 107。
实施例 4
图 5示出根据本发明实施例 4的通信连接建立方法的流程图。如图 5所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介； 另外， 还可 以不使用歩骤 S101 , 而是在开始时进行歩骤 S102和 S301 , 也可以达到后续目 的。
歩骤 S102、 媒介设备 M使其上的连接配置信息列表为空；
歩骤 S301、 媒介设备 M选择多对一模式， 以确定先触碰目标设备、 后触 碰主设备；
歩骤 S103、媒介设备 M触碰一个目标设备 B， 以向该目标设备 B发送切换 请求， 该切换请求可包含承载类型， 然后接收该目标设备 B反馈的切换媒介 响应， 该切换媒介响应包含该目标设备 B的连接配置信息， 从而获取该目标 设备 B的连接配置信息；
歩骤 S104、媒介设备 M将所获取到的连接配置信息保存到连接配置信息 列表中；
歩骤 S105、 媒介设备 M判断是否接收到获取完成命令； 若未接收到， 则 返回执行歩骤 S103; 若接收到， 则确定候选连接配置信息收集完毕， 并继续 执行歩骤 S 107;
歩骤 S107、 媒介设备 M触碰主设备 A， 以向主设备 A发送切换请求， 然 后接收主设备 A反馈的切换媒介响应， 从而获取主设备 A的连接配置信息； 歩骤 S108、媒介设备 M将连接配置信息列表中所保存的连接配置信息与 主设备 A的连接配置信息进行匹配处理， 以得到匹配的连接配置信息；
歩骤 S109、 媒介设备 M向主设备 A发送切换初始化请求， 该切换初始化 请求包含所有目标设备 B的与主设备 A的连接配置信息相匹配的连接配置信 息； 然后接收主设备 A反馈的切换初始化响应， 该切换初始化响应包含主设 备 A针对每个目标设备 B选定的连接配置信息； 与实施例 2类似， 歩骤 S109还 可以包括其他情况， 在此不再赘述；
歩骤 S110、 主设备 A基于其针对每个目标设备 B选定的连接配置信息， 分别初始化其与每个目标设备 B之间的通信连接。
通过将图 5与图 2进行比较， 并结合以上介绍可知， 本实施例与实施例 2 的主要区别在于： 利用歩骤 S301替换歩骤 S106, 即不使用设备选择命令， 而 是根据多对一（即触碰顺序为先触碰目标设备、 再触碰主设备） 的模式选择 来确定主设备和目标设备的身份。
因此， 针对实施例 2的大部分详细解释和特别说明， 例如关于连接配置 信息列表保存的连接配置信息的类型、关于连接配置信息的匹配处理以及关 于切换初始化消息的扩展等， 同样适用于本实施例，并在此不再赘述。并且， 与前述实施例 2、 3类似， 根据本实施例的通信连接建立方法同样可以明显提 高操作简便性。
例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通信连接， 在本 实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次数可以只有 N+1次， 包括： 在接收到获取完成命令之前触碰 N次， 以完成 N个目标设备 B 的连接配置信息收集；在接收到获取完成命令之后触碰 1次， 以获取主设备 A 的连接配置信息并实现主设备 A对主设备 A与每个目标设备 B之间的通信连 接的切换初始化。 即， 与实施例 2、 3相比， 本实施例所需的触碰次数可减少 1次。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以避免 目标设备之间的误连接， 在此不再赘述。
在一种可能的实现方式中， 与实施例 2、 3类似， 媒介设备 M还可以在接 收到获取完成命令之后、 即在歩骤 S105判断为是的情况下， 提示用户所有目 标设备 B的连接配置信息已收集完毕， 以提醒用户使媒介设备 M触碰主设备 A、 即执行歩骤 S107。
需要说明的是， 尽管图 5示出歩骤 S301在歩骤 S102之后执行， 本领域技 术人员能够理解， 本发明应不限于此。 事实上， 歩骤 S301可在歩骤 S102之前 执行， 还可与歩骤 S102同时执行， 只要能够在歩骤 S107之前确定目标设备和 主设备的触碰顺序即可。
实施例 5
图 6示出根据本发明实施例 5的通信连接建立方法的流程图。如图 6所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介； 另外， 还可 以不使用歩骤 S101 , 而是在开始时进行歩骤 S102和 S301 , 也可以达到后续目 的；
歩骤 S102、 媒介设备 M使其上的连接配置信息列表为空；
歩骤 S301、 媒介设备 M选择多对一模式， 以确定先触碰目标设备、 后触 碰主设备；
歩骤 S401、 媒介设备 M将计数器的计数值置为 0， 相当于初始化计数器； 歩骤 S401也可以在 S301之前进行；
歩骤 S103、媒介设备 M触碰一个目标设备 B， 以向该目标设备 B发送切换 请求， 该切换请求可包含承载类型， 然后接收该目标设备 B反馈的切换媒介 响应， 该切换媒介响应包含该目标设备 B的连接配置信息， 从而获取该目标 设备 B的连接配置信息；
歩骤 S402、 媒介设备 M使计数器的计数值加 1 ; S402还可以在 S104之后 且 S105之前的一个时刻进行。
歩骤 S104、媒介设备 M将所获取到的连接配置信息保存到连接配置信息 列表中；
歩骤 S105、 媒介设备 M判断是否接收到获取完成命令； 若未接收到， 则 返回执行歩骤 S103 ; 若接收到， 则确定候选连接配置信息收集完毕， 并继续 执行歩骤 S 107;
歩骤 S107、 媒介设备 M触碰主设备 A， 以向主设备 A发送切换请求， 然 后接收主设备 A反馈的切换媒介响应， 从而获取主设备 A的连接配置信息； 歩骤 S403、 媒介设备 M将计数器的计数值减 1 ;
歩骤 S404、 媒介设备 M将连接配置信息列表中保存的一个目标设备 B的 连接配置信息与主设备 A的连接配置信息进行匹配处理， 以确定该目标设备 B与主设备 A的连接配置信息相匹配的连接配置信息；
歩骤 S405、 媒介设备 M向主设备 A发送切换初始化请求， 该切换初始化 请求包含所确定目标设备 B的与主设备 A的连接配置信息相匹配的连接配置 信息； 然后接收主设备 A反馈的切换初始化响应， 该切换初始化响应包含主 设备 A针对该目标设备 B选定的连接配置信息；
歩骤 S406、 主设备 A基于其针对该目标设备 B选定的连接配置信息， 初 始化其与该目标设备 B之间的通信连接；
歩骤 S407、 媒介设备 M判断计数器的计数值是否大于 0， 若是则返回执 行歩骤 S107， 否则结束本流程。
通过将图 6与图 5进行比较， 并结合以上介绍可知， 本实施例与实施例 4 的主要区别在于：在歩骤 S301与歩骤 S103之间增加了歩骤 S401、并在歩骤 103 之后与歩骤 S104之间增加了歩骤 S402, 以统计目标设备 B的个数； 以及将歩 骤 S108〜S110替换为歩骤 S403〜S407， 以通过连续地触碰主设备 A来依次实现 主设备 A对其与每个目标设备 B之间通信连接的切换初始化， 从而无需对 CH 1.3规范中的 Hi记录进行扩展以包含多个目标设备 B的连接配置信息。
因此， 针对实施例 2〜4的大部分详细解释和特别说明， 例如关于连接配 置信息列表保存的连接配置信息的类型以及关于连接配置信息的匹配处理 等， 同样适用于本实施例， 并在此不再赘述。 并且， 与前述实施例 2〜4类似， 根据本实施例的通信连接建立方法同样可以明显提高操作简便性。
例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通信连接， 在本 实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次数可以最多为 2N次， 包括： 在接收到获取完成命令之前触碰 N次， 以完成 N个目标设备 B 的连接配置信息收集； 在接收到获取完成命令之后触碰 N次， 以获取主设备 A的连接配置信息并实现主设备 A对其与每个目标设备 B之间通信连接的切 换初始化。 与实施例 4相比， 本实施例所需的触碰次数从 N+1增加至 2N。 但 是， 由于无需对现有 CH 1.3规范中的切换初始化消息进行扩展， 并且后面 N 次触碰都是在主设备 A旁连续进行的， 即无需用户手持媒介设备 M在主设备 A与每个目标设备 B之间往返， 根据本实施例的通信连接建立方法仍能够有 效提高用户操作的简便性。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以避免 目标设备之间的误连接， 在此不再赘述。
在一种可能的实现方式中， 与实施例 2〜4类似， 媒介设备 M还可在接收 到获取完成命令之后、 即在歩骤 S105判断为是的情况下， 提示用户所有目标 设备 B的连接配置信息已收集完毕， 以提醒用户使媒介设备 M触碰主设备 A、 即执行歩骤 S107。
需要说明的是， 与实施例 4类似， 尽管图 6示出歩骤 S301在歩骤 S102之后 执行， 本发明应不限于此， 事实上， 歩骤 S301可在歩骤 S102之前执行， 还可 与歩骤 S102同时执行，只要能够在歩骤 S107之前确定主设备和目标设备的触 碰顺序即可。
此外， 尽管图 6示出歩骤 S403在歩骤 S404之前执行， 本发明应不限于此， 事实上歩骤 S403还可在歩骤 S404、 S405和 S406中任一之后执行，只要能够在 歩骤 S107之后并且歩骤 S407之前完成计数器的计数值的更新即可。

歩骤 S109、 媒介设备 M向主设备 A发送切换初始化请求， 该切换初始化 请求包含所有目标设备 B的与主设备 A的连接配置信息相匹配的连接配置信 息； 然后接收主设备 A反馈的切换初始化响应， 该切换初始化响应包含主设 备 A针对每个目标设备 B选定的连接配置信息； 与实施例 2类似， 歩骤 S109还 可以包括其他情况， 在此不再赘述；
歩骤 S110、 主设备 A基于其针对每个目标设备 B选定的连接配置信息， 分别初始化其与每个目标设备 B之间的通信连接。
通过将图 7与图 6进行比较， 并结合以上介绍可知， 本实施例与实施例 5 的主要区别在于： 在歩骤 S401之前增加了歩骤 S501、 并将歩骤 105替换为歩 骤 502， 以基于设定的目标设备个数 N来判断候选连接配置信息是否收集完 毕， 而无需使用获取完成命令； 以及， 将歩骤 S403〜S407替换为歩骤 S108〜S110，以通过仅 1次触碰主设备 A来实现主设备 A对主设备 A与每个目标 设备 B之间的通信连接的切换初始化， 而无需连续地触碰主设备 A多次。
因此， 针对实施例 2〜5的大部分详细解释和特别说明， 例如关于连接配 置信息列表保存的连接配置信息的类型、关于连接配置信息的匹配处理以及 关于切换初始化消息的扩展等， 同样适用于本实施例， 并在此不再赘述。 并 且， 与前述实施例 2〜5类似， 根据本实施例的通信连接建立方法同样可以明 显提高操作简便性。
例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通信连接， 在本 实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次数可以为 N+1 次， 包括： 先触碰 N次， 以完成 N个目标设备 B的连接配置信息收集； 再触碰 1次， 以获取主设备 A的连接配置信息并实现主设备 A对主设备 A与每个目标 设备 B之间的通信连接的切换初始化。 SP， 本实施例与实施例 4所需的触碰次 数一样。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以避免 目标设备之间的误连接， 在此不再赘述。
在一种可能的实现方式中， 与实施例 2〜5类似， 媒介设备 M还可在触碰 了 N个目标设备 B之后、 即在歩骤 S502判断为是的情况下， 提示用户所有目 标设备 B的连接配置信息已收集完毕， 以提醒用户使媒介设备 M触碰主设备 A、 即执行歩骤 S107。
需要说明的是， 与实施例 4、 5类似， 尽管图 7示出歩骤 S301在歩骤 S102 之后执行， 本发明应不限于此， 事实上， 歩骤 S301可在歩骤 S102之前执行， 还可与歩骤 S102同时执行，只要能够在歩骤 S107之前确定主设备和目标设备 的触碰顺序即可。
此外， 尽管图 7示出歩骤 S501在歩骤 S401之前执行， 本发明应不限于此， 事实上歩骤 S501还可跟歩骤 S401合并，还可在歩骤 S102、 S301和 S401中任一 之前执行， 只要能够在歩骤 S103之前确定目标设备的个数即可。
以及， 尽管图 7示出歩骤 S402在歩骤 S104之前执行， 本发明应不限于此， 事实上歩骤 S402还可在歩骤 S104之后执行，只要能够在歩骤 S103之后并且歩 骤 S502之前完成计数器的计数值的更新即可。 实施例 7
图 8示出根据本发明实施例 7的通信连接建立方法的流程图。如图 8所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介； 另外， 还可 以不使用歩骤 S101 , 而是在开始时进行歩骤 S102和 S301 , 也可以达到后续目 的；
歩骤 S102、 媒介设备 M使其上的连接配置信息列表为空；
歩骤 S301、 媒介设备 M选择多对一模式， 以确定先触碰目标设备、 后触 碰主设备；
歩骤 S501、 媒介设备 M接收数量指示命令， 以确定目标设备的个数 N; 歩骤 S401、 媒介设备 M将计数器的计数值置为 0;
歩骤 S103、媒介设备 M触碰一个目标设备 B， 以向该目标设备 B发送切换 请求， 该切换请求可包含承载类型， 然后接收该目标设备 B反馈的切换媒介 响应， 该切换媒介响应包含该目标设备 B的连接配置信息， 从而获取该目标 设备 B的连接配置信息；
歩骤 S104、媒介设备 M将所获取到的连接配置信息保存到连接配置信息 列表中；
歩骤 S402、 媒介设备 M使计数器的计数值加 1 ;
歩骤 S502、 媒介设备 M判断计数器的计数值是否小于 N; 若是， 则返回 执行歩骤 S103 ; 若否， 则确定候选连接配置信息收集完毕， 并继续执行歩骤 S107;
歩骤 S107、 媒介设备 M触碰主设备 A， 以向主设备 A发送切换请求， 然 后接收主设备 A反馈的切换媒介响应， 从而获取主设备 A的连接配置信息； 歩骤 S403、 媒介设备将计数器的计数值减 1 ; 歩骤 S404、 媒介设备 M将连接配置信息列表中保存的一个目标设备 B的 连接配置信息与主设备 A的连接配置信息进行匹配处理， 以确定该目标设备 B与主设备 A的连接配置信息相匹配的连接配置信息；
歩骤 S405、 媒介设备 M向主设备 A发送切换初始化请求， 该切换初始化 请求包含所确定目标设备 B的与主设备 A的连接配置信息相匹配的连接配置 信息； 然后接收主设备 A反馈的切换初始化响应， 该切换初始化响应包含主 设备 A针对该目标设备 B选定的连接配置信息 ·'
歩骤 S406、 主设备 A基于其针对该目标设备 B选定的连接配置信息， 初 始化其与该目标设备 B之间的通信连接；
歩骤 S407、 媒介设备 M判断计数器的计数值是否大于 0， 若是则返回执 行歩骤 S107, 否则结束本流程。
通过将图 8与图 7进行比较， 并结合以上介绍可知， 本实施例与实施例 6 的主要区别在于：将歩骤 S108〜S110替换为歩骤 S403〜S407， 以通过连续地触 碰主设备 A来依次实现主设备 A对其与每个目标设备 B之间通信连接的切换 初始化， 从而无需对 CH 1.3规范中的 Hi记录进行扩展以包含多个目标设备 B 的连接配置信息。
因此， 针对实施例 2〜6的大部分详细解释和特别说明， 例如关于连接配 置信息列表保存的连接配置信息的类型以及关于连接配置信息的匹配处理 等， 同样适用于本实施例， 并在此不再赘述。 并且， 与前述实施例 2〜6类似， 根据本实施例的通信连接建立方法同样可以明显提高操作简便性。
例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通信连接， 在本 实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次数可以最多为 2N次， 包括： 先触碰 N次， 以完成 N个目标设备 B的连接配置信息收集； 再 触碰 N次，以获取主设备 A的连接配置信息并实现主设备 A对其与每个目标设 备 B之间通信连接的切换初始化。与实施例 6相比， 本实施例所需的触碰次数 从 N+l增加至 2N。 但是， 与实施例 5—样， 由于无需对现有 CH 1.3规范中的 切换初始化消息进行扩展， 并且后面 N次触碰都是在主设备 A旁连续进行的， 即无需用户手持媒介设备 M在主设备 A与每个目标设备 B之间往返，根据本实 施例的通信连接建立方法仍能够有效提高用户操作的简便性。
与前述实施例 2类似， 根据本实施例的通信连接建立方法同样可以避免 目标设备之间的误连接， 在此不再赘述。
在一种可能的实现方式中， 与实施例 2〜6类似， 媒介设备 M还可在触碰 了 N个目标设备 B之后、 即在歩骤 S502判断为是的情况下， 提示用户所有目 标设备 B的连接配置信息已收集完毕， 以提醒用户使媒介设备 M触碰主设备 A、 即执行歩骤 S107。
需要说明的是， 与实施例 4〜6类似， 尽管图 8示出歩骤 S301在歩骤 S102 之后执行， 本发明应不限于此， 事实上， 歩骤 S301可在歩骤 S102之前执行， 还可与歩骤 S102同时执行，只要能够在歩骤 S107之前确定主设备和目标设备 的触碰顺序即可。
此外， 与实施例 6类似， 尽管图 8示出歩骤 S501在歩骤 S401之前执行， 本 发明应不限于此， 事实上， 歩骤 S501还可在歩骤 S102、 S301和 S401中任一之 前执行， 只要能够在歩骤 S103之前确定目标设备的个数即可。
以及尽管图 8示出歩骤 S403在歩骤 S404之前执行， 本发明应不限于此， 事实上， 歩骤 S403还可在歩骤 S404、 S405和 S406中任一之后执行， 只要能够 在歩骤 S107之后并且歩骤 S407之前完成计数器的计数值的更新即可。
实施例 8
图 9示出根据本发明实施例 8的通信连接建立方法的流程图。如图 9所示， 该方法主要包括：
歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介； 在本实施例 中也可以省略本歩骤， 直接执行歩骤 S701 ;
歩骤 S701、 媒介设备 M选择一对多模式， 以确定先触碰主设备、 后触碰 目标设备；
歩骤 S702、 媒介设备 M触碰主设备 A， 并向主设备 A发送切换请求， 该 切换请求可包含承载类型， 然后接收主设备 A反馈的切换媒介响应， 该切换 媒介响应包含主设备 A的连接配置信息， 从而获取主设备 A的连接配置信息； 歩骤 S703、媒介设备 M触碰一个目标设备 B，并向该目标设备 B发送切换 请求， 然后接收该目标设备 B反馈的切换媒介响应， 从而获取该目标设备 B 的连接配置信息；
歩骤 S704、 媒介设备 M将该目标设备 B的连接配置信息与主设备 A的连 接配置信息进行匹配处理， 以确定主设备 A的与该目标设备 B的连接配置信 息相匹配的连接配置信息；
歩骤 S705、 媒介设备 M向该目标设备 B发送切换初始化请求， 该切换初 始化请求包含主设备 A的与该目标设备 B的连接配置信息相匹配的连接配置 信息； 然后接收该目标设备 B反馈的切换初始化响应， 该切换初始化响应包 含该目标设备 B针对主设备 A选定的连接配置信息；
歩骤 S706、 该目标设备 B基于其针对主设备 A选定的连接配置信息， 初 始化其与主设备 A之间的通信连接；
歩骤 S707、 媒介设备 M保存主设备 A的连接配置信息， 同时释放该目标 设备 B的连接配置信息； 例如删除或者标记为不可用；
歩骤 S708、 媒介设备 M判断是否接收到建立完成命令， 若未接收到， 则 返回执行歩骤 S703 , 若接收到， 则结束本流程。
对于歩骤 S707 , 在一种可能的实现方式中， 媒介设备 M可仅保存主设备 A的特定类型的连接配置信息、 例如蓝牙连接配置信息。 并且， 在这种实现 方式下， 在歩骤 S704中， 媒介设备 M只需将所保存的蓝牙连接配置信息与该 目标设备 B的蓝牙连接配置信息进行匹配。 在一种可能的具体实现方式中， 若某一目标设备 B反馈的切换媒介响应中不包含所述特定类型的连接配置信 息、 例如不包含蓝牙连接配置信息， 则媒介设备 M可输出告警消息以提醒用 户该目标设备 B不支持所述特定类型的连接。
或者， 在另一种可能的实现方式中， 在歩骤 S707中， 媒介设备 M可保存 主设备 A的所有类型的连接配置信息，例如蓝牙连接配置信息和 Wi-Fi连接配 置信息等都保存。 并且， 在这种实现方式下， 在歩骤 S704中， 媒介设备 M将 按连接类型进行匹配处理， 例如将所保存的蓝牙连接配置信息与目标设备 B 的蓝牙连接配置信息进行匹配、将所保存的 Wi-Fi连接配置信息与目标设备 B 的 Wi-F涟接配置信息进行匹配； 当然，媒介设备 M还可以针对某特定类型的 连接进行优先匹配处理，例如优先匹配连接配置信息列表中所保存的蓝牙连 接配置信息与主设备 A的蓝牙连接配置信息。
此外， 在一种可能的实现方式中， 与实施例 2〜7类似， 媒介设备 M可使 用连接配置信息列表来保存主设备 A的连接配置信息。 在这种实现方式下， 在歩骤 S702之前还要执行歩骤 S102, 以使媒介设备 M将其上的连接配置信息 列表置为空。
通过将图 9与图 5进行比较， 并结合以上介绍可知， 本实施例与实施例 4 的主要区别在于： 利用歩骤 S701替换歩骤 S301 , 从而根据一对多（即触碰顺 序为先触碰主设备、 再触碰目标设备） 的模式选择来确定主设备和目标设备 的身份，而不是根据多对一（即触碰顺序为先触碰目标设备、再触碰主设备） 的模式选择来确定主设备和目标设备的身份； 以及， 利用歩骤 S702替换歩骤 S103〜S105、利用歩骤 S703〜708替换歩骤 S107〜S110， 以使媒介设备 M持续保 存主设备 A的连接配置信息直至接收到建立完成命令， 并在接收到建立完成 命令之前每触碰一个目标设备 B, 就获取该目标设备 B的连接配置信息并实 现该目标设备 B对主设备 A的切换初始化。 换言之，通过在基于一对多的模式选择确定了主设备和目标设备的身份 之后，使媒介设备 M保存主设备 A的连接配置信息直至接收到建立完成命令， 并在接收到建立完成命令之前每触碰一个目标设备 B, 获取目标设备 B的连 接配置信息并实现该目标设备 B对主设备 A的切换初始化， 根据本实施例的 通信连接建立方法明显减少了整个通信连接建立过程中媒介设备 M所需的 触碰次数、 即提高了操作简便性。
例如， 假设要辅助主设备 A建立与 N个目标设备 B之间的通信连接， 在本 实施例的整个通信连接建立过程中，媒介设备 M所需的触碰次数只有 N+1次， 包括： 先触碰 1次， 以获取主设备 A的连接配置信息； 之后触碰 N次， 以完成 N个目标设备 B的连接配置信息收集， 并实现每个目标设备 B对主设备 A的切 换初始化。 SP， 本实施例所需的触碰次数与实施例 4、 6—样。 此外， 本实施 例通过媒介设备 M保存主设备 A的连接配置信息，释放目标设备 B的连接配置 信息， 可有效避免目标设备 B之间的误连接。 因此， 与前述实施例 2〜7类似， 根据本实施例的通信连接建立方法同样可以获得有效避免误连接并明显提 高操作简便性的有益效果。
在一种可能的实现方式中， 媒介设备 M还可在接收到建立完成命令之 后、 即在歩骤 S708判断为是的情况下， 提示用户所有目标设备 B均与主设备 建立了通信连接， 以提醒用户整个通信连接建立过程完毕。
需要说明的是， 尽管图 9示出歩骤 S701在歩骤 S702之前执行， 本领域技 术人员应能理解， 本发明应不限于此。 事实上， 歩骤 S701还可在歩骤 S702 之后执行， 或者与歩骤 S702同时执行， 只要能够在歩骤 S703之前确定主设备 和目标设备的触碰顺序即可。
实施例 9
图 10示出根据本发明实施例 9的通信连接建立方法的流程图。 如图 10所 示， 该方法主要包括： 歩骤 S101、 媒介设备 M接收角色指示命令， 以确定其要作为基于 NFC辅 助一个主设备 A建立与多个目标设备 B的通信连接的切换媒介； 在本实施例 中也可以省略本歩骤， 直接执行歩骤 S701 ;
歩骤 S701、 媒介设备 M选择一对多模式， 以确定先触碰主设备、 后触碰 目标设备；
歩骤 S702、 媒介设备 M触碰主设备 A， 并向主设备 A发送切换请求， 该 切换请求可包含承载类型， 然后接收主设备 A反馈的切换媒介响应， 该切换 媒介响应包含主设备 A的连接配置信息， 从而获取主设备 A的连接配置信息； 歩骤 S801、 媒介设备 M接收数量指示命令， 以确定目标设备 B的个数 N; 歩骤 S802、 媒介设备 M将计数器的计数值置为 0;
歩骤 S703、媒介设备 M触碰一个目标设备 B，并向该目标设备 B发送切换 请求， 然后接收该目标设备 B反馈的切换媒介响应， 从而获取该目标设备 B 的连接配置信息；
歩骤 S704、 媒介设备 M将该目标设备 B的连接配置信息与主设备 A的连 接配置信息进行匹配处理， 以确定主设备 A的与该目标设备 B的连接配置信 息相匹配的连接配置信息；
歩骤 S705、 媒介设备 M向该目标设备 B发送切换初始化请求， 该切换初 始化请求包含主设备 A的与该目标设备 B的连接配置信息相匹配的连接配置 信息； 然后接收该目标设备 B反馈的切换初始化响应， 该切换初始化响应包 含该目标设备 B针对主设备 A选定的连接配置信息；
歩骤 S706、 该目标设备 B基于其针对主设备 A选定的连接配置信息， 初 始化其与主设备 A之间的通信连接；
歩骤 S707、 媒介设备 M保存主设备 A的连接配置信息， 同时释放该目标 设备 B的连接配置信息； 例如删除或者标记为不可用；
歩骤 S803、 媒介设备 M将计数器的计数值加 1 ; 歩骤 S804、 媒介设备判断计数器的计数值是否小于 N， 若是， 则返回执 行歩骤 S703 , 若否， 则结束本流程。
通过将图 10与图 9进行比较， 并结合以上介绍可知， 本实施例与实施例 8 的主要区别在于：在歩骤 S703之前增加了歩骤 S801〜S802、并将歩骤 708替换 为歩骤 803〜804，以基于设定的目标设备个数 N来判断整个通信连接建立过程 是否完毕， 而无需使用建立完成命令。
因此， 针对实施例 8的大部分详细解释和特别说明， 同样适用于本实施 例， 并在此不再赘述。 并且， 与前述实施例 2〜8类似， 根据本实施例的通信 连接建立方法同样可以明显提高操作简便性。
例如， 假设要辅助建立主设备 A分别与 N个目标设备 B之间的通信连接， 在本实施例的整个通信连接建立过程中， 媒介设备 M所需的触碰次数可以为 N+1次， 包括： 先触碰 1次， 以获取主设备 A的连接配置信息； 之后触碰 N次， 以完成 N个目标设备 B的连接配置信息收集，并实现每个目标设备 B对主设备 A的切换初始化。 SP， 本实施例所需的触碰次数与实施例 4、 6、 8—样， 其中 实施例 4及实施例 6需要对现有切换初始化消息进行扩展才能达到减少碰触 次数的技术效果， 实施例 8及本实施例则可以在无需对现有切换初始化消息 进行扩展的情况下， 实现减少碰触次数简化操作流程的技术效果。
此外， 本实施例通过媒介设备 M保存主设备 A的连接配置信息， 释放目 标设备 B的连接配置信息， 可有效避免目标设备 B之间的误连接。 因此， 与 前述实施例 2〜7类似， 根据本实施例的通信连接建立方法同样可以获得有效 避免误连接并明显提高操作简便性的有益效果。
在一种可能的实现方式中， 与实施例 8类似， 媒介设备 M还可在触碰了 N 个目标设备之后、 即在歩骤 S804判断为否的情况下， 提示用户所有目标设备 B均与主设备建立了通信连接， 以提醒用户整个通信连接建立过程完毕。
需要说明的是， 与实施例 8类似， 尽管图 10示出歩骤 S701在歩骤 S702之 前执行， 本发明应不限于此， 事实上， 歩骤 S701还可在歩骤 S702之后执行， 只要能够在歩骤 S703之前确定主设备和目标设备的触碰顺序即可。
此外，尽管图 10示出歩骤 S801在歩骤 S802之前执行，本发明应不限于此， 事实上， 歩骤 S801还可在歩骤 S802之后执行， 或者与歩骤 S802同时执行， 还 可以在歩骤 S702之前执行，只要能够在歩骤 S703之前确定目标设备的个数即 可。
以及，尽管图 10示出歩骤 S803在歩骤 S707之后执行，本发明应不限于此， 事实上， 歩骤 S803可在歩骤 S703、 S704、 S705、 S706和 S707中任一之前执 行，只要能够在歩骤 S802之后并且歩骤 S804之前完成计数器的计数值的更新 即可。
