具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
蓝牙技术是一种支持设备短距离通信的无线电技术，能够在蓝夜设备之间进行无线信息交换。其中，蓝牙设备可以是移动终端、智能手机、平板电脑、智能家电(比如智能音箱、智能冰箱、智能空调等)、可穿戴式智能设备(比如智能眼镜、智能手表等)、智能传感器(比如温度传感器、门窗传感器等)，本申请实施例不对蓝牙设备的设备类型进行限定。
示例性的，蓝牙设备为蓝牙广播源设备和蓝牙广播接收端设备中的一种。其中，蓝牙广播源设备用于发送蓝牙广播的相关数据，蓝牙广播接收端设备用于接收源设备发送的蓝牙广播的相关数据，从而实现蓝牙通信。
示意性的，蓝牙广播通过广播包的传输来实现。
其中，广播包的协议数据单元(Protocol Data Unit，PDU)类型有多种，包括但不限于如下类型中的至少一种：广播扩展指示帧(Advertising Extension Indication，ADV_EXT_IND)、辅助广播指示帧(Auxilary Advertising Indication，AUX_ADV_IND)、辅助同步指示帧(Auxilary Synchronization Indication，AUX_SYNC_IND)和辅助链指示帧(Auxilary Chain Indication，AUX_CHAIN_IND)。
以第一蓝牙设备和第二蓝牙设备进行蓝牙广播的传输为例：第一蓝牙设备发送第一扩展广播包，比如AUX_SYNC_IND数据包，第一扩展广播包中携带有数据信息，第二蓝牙设备通过接收第一扩展广播包来获取数据信息。
在传输过程中，由于数据信息的长度较长，存在超出第一扩展广播包的最长单帧帧长的可能性，也即第一扩展广播包中无法携带数据信息的全部内容的可能性。基于此，需要增加一个或多个第二扩展广播包，比如AUX_CHAIN_IND数据包，将数据信息的剩余内容携带在第二扩展广播包中，以实现数据的完整发送。
参考图1，蓝牙广播的传输过程具体阐述如下：
蓝牙广播源设备发送ADV_EXT_IND数据包，ADV_EXT_IND数据包用于指示蓝牙广播接收端设备接收AUX_ADV_IND数据包；接收端设备在接收到 ADV_EXT_IND数据包后，获取到AUX_ADV_IND数据包的接收指令；随后，源设备发送AUX_ADV_IND数据包，AUX_ADV_IND数据包用于指示接收端设备接收AUX_SYNC_IND数据包；接收端在接收到AUX_ADV_IND数据包后，获取到AUX_SYNC_IND数据包的接收指令；随后，源设备发送AUX_SYNC_IND数据包，接收端接收AUX_SYNC_IND数据包。
其中，AUX_SYNC_IND的帧结构如图2所示。在该帧结构的有效荷载中包括四个字段，分别是广播数据信息(Advertising Data Information，ADI)、辅助指针(AuxilaryPtrl，Aux Ptr)、额外广播数据、广播数据(Advertising Data，Adv数据)。示意性的，Aux Ptr字段是可选字段，广播数据字段中携带有蓝牙广播音频流元数据(Broadcast Audio Stream Metadata)。
参考图1，在蓝牙广播音频流元数据的数据长度超过AUX_SYNC_IND的情况下，源设备可选地发送一个或多个AUX_CHAIN_IND，AUX_CHAIN_IND中携带有蓝牙广播音频流元数据的部分内容。
其中，AUX_CHAIN_IND的帧结构如图3所示。在该帧结构的有效荷载中包括三个字段，分别是ADI、Aux Ptr、广播数据。示意性的，ADI字段和Aux Ptr字段是可选字段。
示例性的，在蓝牙广播音频流元数据的数据长度超过AUX_SYNC_IND的最长单帧帧长时，蓝牙广播音频流元数据中超过AUX_SYNC_IND的最长单帧帧长的部分内容被携带在AUX_CHAIN_IND中，比如携带在AUX_CHAIN_IND的广播数据字段中；AUX_CHAIN_IND的ADI字段跟随AUX_SYNC_IND的ADI字段出现而出现；AUX_CHAIN_IND和AUX_SYNC_IND中包括的Aux Ptr字段在需要发送AUX_CHAIN_IND的情况下使用。
其中，Aux Ptr字段可参考如下表格的描述：
Figure PCTCN2021109951-appb-000001
示例性的，频道索引用于描述接收蓝牙广播的数据包的位置；辅助类型数据包偏移量用于描述接收数据包的时间点与当前时间的间隔量，该间隔量用偏移单位表示，比如，接收数据包的时间点与当前时间间隔2个偏移单位；辅助类型数据包物理层用于指示接收数据包物理层位置。

在一种可选的实施场景下，本申请实施例所涉及的URL地址可实现为URL短地址，用于减少蓝牙广播同步信息的长度。其中，URL短地址的格式、字节大小可根据协议标准或者实际需要来设定。
示例性的，URL地址指向的数据中携带有目标信息，其中，URL地址指向网页或者二维码中的至少一种。可选的，目标信息携带在URL地址指向的网页数据中。其中，网页数据中包括但不限于如下中的至少一种：文字信息、图片信息、音频信息、视频信息。比如，URL地址指向的网页数据中包括一首歌曲的文字信息、图片信息和音频信息，目标信息是歌曲的音频信息。
