Description

通信方法及装置 技术领域
本申请涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
数据分享，是指一个设备将数据，如音频发送给其他设备，如同事、朋友、或者其他人群等的设备的过程。其中，数据分享的一种常见方式是蓝牙分享。
目前，可以基于点对点多连接方案和广播方案实现数据的蓝牙分享。具体地，点对点多连接方案中，分享设备通过与多个被分享设备分别建立的点对点连接，向各个被分享设备各发送一份待分享数据的副本(copy)。广播方案中，分享设备通过广播，向所有被分享设备发送一份待分享数据。
上述两种方案，都需要发送多份待分享数据的副本或多份待分享数据，占用较多空口资源。由于蓝牙采用跳频扩频(frequency hoppingspread spectrum，FHSS)方式通信，需要将频带划分为多个子频带，同一设备每个时刻在一个子频带上工作，从而导致同一设备每个时刻只占用部分带宽，单位时间内传输的数据量较少，无法支持高质量的蓝牙分享。另外，由于蓝牙和无线保真(wireless fidelity，WiFi)都工作在2.4吉赫兹(giga hertz，GHz)频段，且分享设备的蓝牙和WiFi可能需要共用同一天线，可能导致蓝牙分享与WiFi通信抢占空口资源的情况，如蓝牙分享只能在部分时间内完成，数据传输速率有限，同样无法支持高质量的蓝牙分享。此外，受限于电池容量，分享设备的发射功率通常较小，也无法支持长距离数据分享。
发明内容
本申请实施例提供一种通信方法及装置，能够解决分享设备单位时间内传输数据量受限以及分享距离短的问题，从而提高数据质量以及被分享的设备数量。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种通信方法。该方法应用于转发设备。该通信方法包括：转发设备接收来自终端设备的分享指示信息，其中，分享指示信息用于指示分享第一数据，第一数据为终端设备的待分享数据；转发设备获取第一数据，并根据分享指示信息，将第一数据以无线广播方式发送给多个接收终端。

图2-图5中示出的设备的结构并不构成对设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
需要说明的是，上述设备为接入上述通信系统，且具有数据收发功能的终端或可设置于该终端的芯片或芯片系统。
应当指出的是，本申请实施例中的方案还可以应用于其他通信系统中，相应的名称也可以用其他通信系统中的对应功能的名称进行替代。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他设备，图1中未予以画出。
下面将结合图6-图12详细阐述本申请实施例提供的通信方法。
示例性地，图6为本申请实施例提供的一种通信方法的流程示意图一。该通信方法可以适用于图1所示的通信系统中转发设备101与终端设备102之间的通信，以及转发设备101与接收设备103之间的通信。如图6所示，该通信方法包括如下步骤：
S601，终端设备向转发设备发送分享指示信息，转发设备接收来自终端设备的分享指示信息。
其中，分享指示信息用于指示分享第一数据，第一数据为终端设备的待分享数据。
示例性地，第一数据为终端设备的待分享数据，即第一数据为需要通过终端设备发送给转发设备分享的数据，或者终端设备指示转发设备分享的数据。
可选地，分享指示信息可以包括如下一项或多项：第一数据的重传次数、或发射功率。
示例性地，重传次数是指转发设备采用广播方式发送待分享数据时，发送待分享数据的次数。例如，待分享数据为第一数据时，若重传次数为2，则转发设备发送第一数据时，在一个广播周期内每一个数据包发送2次。图7为蓝牙广播的数据包发送示意图。以下结合图7说明。
如图7所示，时间t1-时间t2之间为第一个广播周期，蓝牙在广播时，发送的数据包括数据P0、数据P1、数据P2和数据P3，数据P0和数据P1属于一个数据包，数据P2和数据P3属于一个数据包。蓝牙主设备每次发送一个数据包。当需要广播数据P0-数据P3时，蓝牙主设备根据广播周期和重传次数发送数据。具体地，蓝牙主设备首先在第一个广播周期内发送一次数据P0和数据P1，然后在第一个广播周期内再次发送数据P0和数据P1。这样，蓝牙主设备需要发送两次数据包，每次发送的数据包都可能被接收设备接收，则每多发一次数据包，接收设备接收到数据包中数据的概率就增大一些。例如，在数据分享中，重传次数为4，则相较于重传次数为2的情况，接收设备接收到第一数据的概率会增加。
示例性地，发射功率是指转发设备发送数据的功率大小。
例如，接收设备与转发设备之间的最大距离为L，若转发设备当前的发射功率不能覆盖半径为L的区域，则可以调整转发设备的发射功率，以使得与转发设备之间的距离大于或等于L的接收设备也能够接收到第一数据。
可以理解的是，分享指示信息还可以包括转发设备广播的物理信道配置信息。
如此，可以通过终端设备确定转发设备的重传次数，多次重传第一数据，增加接收设备接收到第一数据的概率，能够提高数据分享的可靠性。通过终端设备确定转发设备的发射功率，从而可以确保合适的分享范围。
示例性地，终端设备可以通过无线，如蓝牙、WiFi，或者有线，如光纤、电缆，向转发设备发送分享指示信息。

一种可能的设计方案中，在S601，终端设备向转发设备发送分享指示信息，转发设备接收来自终端设备的分享指示信息之前，图6所示的通信方法还可以包括步骤4。
步骤4，终端设备与转发设备创建通信连接。
示例性地，终端设备判断：终端设备与转发设备之间是否存在通信连接。若不存在通信连接，则终端设备与转发设备创建通信连接。例如，终端设备获取转发设备的设备地址，并基于该设备地址与终端设备创建通信连接。需要说明的是，本申请实施例中，还可以由转发设备发起通信连接的创建流程。由转发设备创建通信连接的实现可以参照终端设备创建通信连接的实现方式，在此不再赘述。
示例性地，转发设备与终端设备之间的通信连接，可以通过蓝牙、WiFi等无线方式实现，还可以通过电缆、光纤等有线方式实现，本申请实施例对此不作具体限定。
可以理解的是，在步骤4，终端设备与转发设备创建通信连接后，转发设备可以向终端设备发送第四信息，用于指示转发设备与终端设备之间的通信连接成功创建。
需要说明的是，本申请实施例中，步骤1-步骤4的顺序并不代表步骤执行的先后顺序。例如，上述步骤1可以位于步骤2之前，或者位于步骤2与步骤3之间，也可以位于步骤3之后。步骤4可以位于步骤2之前，或者位于步骤2与步骤3之间，也可以位于步骤3之后。步骤4可以位于步骤2之前或者位于步骤2之后，本申请实施例并不具体限定步骤1-步骤4的先后顺序。
为了帮助理解创建通信连接的过程，以下以基于蓝牙创建通信连接和基于WiFi创建通信连接为例说明。
图8为转发设备与终端设备基于蓝牙创建通信连接的流程示意图。如图8所示，转发设备与终端设备创建通信连接的步骤包括S601-1至S601-3：
S601-1，终端设备获取转发设备的蓝牙地址。
S601-2，终端设备根据转发设备的蓝牙地址，创建蓝牙连接。
S601-3，终端设备获取蓝牙连接标识。
示例性地，蓝牙连接标识是与基于蓝牙创建通信连接的两个设备，如转发设备和终端设备对应的信息，可以用于标识两个设备之间的通信连接。
以下结合蓝牙的异步面向连接(asynchronous connection-oriented，ACL)进一步说明。
具体地，终端设备通过主机蓝牙协议栈的通用访问配置文件(generic access profile， GAP)协议扫描蓝牙，获得转发设备(通常为耳机等)的蓝牙地址和名字信息。然后，终端设备通过主机蓝牙协议栈的GAP协议，与转发设备创建ACL连接，该ACL连接创建好后，终端设备获取该ACL连接的连接标识。如此，转发设备与终端设备之间便成功创建通信连接。
图9为转发设备与终端设备基于WiFi创建通信连接的流程示意图。如图9所示，转发设备与终端设备基于WiFi创建通信连接的流程包括S601-4至S601-6。
S601-4，终端设备获取无线访问节点(access point，AP)列表。
示例性地，终端设备可以调用主机WiFi模块的扫描接口，以获取AP列表。
S601-5，终端设备根据转发设备的服务集标识(service set identifier，SSID)，调用终端设备中WiFi模块的连接接口。
示例性地，转发设备的SSID，可以根据AP列表的选择结果确定。例如，用户通过人机交互界面，选中了AP列表中的第三个SSID，则AP列表中的第三个SSID所对应的设备即为转发设备，AP列表中的第三个SSID即为转发设备的SSID。
S601-6，终端设备获取WiFi连接的连接状态和连接标识。
其中，连接状态用于指示终端设备与转发设备之间基于WiFi的通信连接是否创建成功和信号质量等。WiFi连接的标识是基于WiFi创建的通信连接对应的信息，可以用于识别通信连接。
以上基于蓝牙和基于WiFi创建通信连接的过程仅用于作示例，并不具体限定创建通信连接的方式。

可选地，在S602转发设备接收第一数据之前，图6所示的通信方法还包括：接收来自终端设备的解密信息。
其中，解密信息用于解析终端设备与蓝牙设备之间传输的第一数据。
具体地，解密信息用于解析终端设备与蓝牙设备之间，通过蓝牙连接传输的数据，以获取第一数据。例如，终端设备与蓝牙设备之间可以传输第一数据的密文，在终端设备与蓝牙设备之间通过蓝牙连接时，转发设备可以根据解密信息设置硬件电路的解密信息。如此，转发设备在接收到第一数据密文后，便可以通过设置好解密信息的硬件电路解密第一数据密文，从而获得第一数据的明文。
可选地，解密信息可以包括：EN_RAND随机数(用于密钥加密)、连接密钥、蓝牙连接的主设备地址、主设备的蓝牙时钟、认证加密偏移量(authenticated ciphering offset，ACO)和主设备的蓝牙时钟相对于连接的主设备蓝牙时钟的偏移值。
例如，转发设备可以首先根据解密信息获取加密密钥，然后根据解密信息以及加密密钥设置硬件电路的解密信息，以解析第一数据。

基于图6所示的通信方法，转发设备(即辅助分享设备)可以获取第一数据，以 及根据终端设备(即主分享设备)的分享指示信息，向多个接收终端(即被分享设备)分享第一数据，即转发设备可以协助终端设备完成数据分享。其中，主分享设备可以为空口资源和/或发射功率受限设备，辅助分享设备可以为空口资源和/或发射功率不受限设备。如此，终端设备可以利用WiFi或有线等通信方式向转发设备发送第一数据，由于WiFi通信在同一时刻占用的频带更宽，相比蓝牙等短距离无线通信技术有更高的速率，而有线方式可以进一步摆脱蓝牙和WiFi通信等短距离无线通信的速率限制，采用这两种方式均可以在单位时间内发送更大的数据量，且转发设备在获取高质量的待分享数据之后，可以再通过无线广播的方式分享给如蓝牙音箱等多个接收终端，从而能够发送高质量的待分享数据，确保分享质量。或者，终端设备向转发设备发送待分享数据，可以利用重复发送待分享数据的空口资源，发送待分享数据的不同部分，可以实现更高质量的待分享数据的分享，既可以确保分享质量，又可以减少终端设备发送的数据量，从而减少主分享设备的资源开销和功耗，以兼顾数据分享业务和其他业务。
并且，转发设备作为终端设备分享数据的中继设备，能够向更多设备分享数据，以扩大分享范围，从而提高数据分享的效率。
此外，终端设备可以用更小的发射功率向转发设备发送数据，从而能够节省功耗，延长续航时间。
