- “maintaining Wi-Fi link” has the same meaning as “maintaining Wi-Fi connection”. The meaning includes that under Wi-Fi communication, the communication device senses that the peer communication device is in a powered-on state and both parties in the communication The distance between them is within the effective communication range.
- “Working state” refers to the state in which the communication device transmits service data packets.
- “Sleep state” is a state in which no service data packets are transmitted relative to the "working state” and can also be called a standby state. Regardless of “sleep state” or “working state”, the relevant functional modules in the communication equipment need to be powered on. This is explained uniformly and will not be repeated below. In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first provided as follows.
- the access point (AP) periodically sends beacon frames to the station (station, STA) through the Wi-Fi link.
- the STA receives the beacon frame from the AP through the Wi-Fi link, indicating that the AP is powered on and the distance between the AP and the STA is within the effective communication range.
- the STA knows that the Wi-Fi link with the AP is not disconnected.
- the STA periodically sends keepalive frames to the AP through the Wi-Fi link.
- the transmission period of the keep-alive frame is usually an integer multiple of the transmission period of the beacon frame, and the keep-alive frame does not carry data.
- the AP receives the beacon frame from the STA through the Wi-Fi link, indicating that the STA is powered on and the distance between the STA and the AP is within the effective communication range. Therefore, the AP will not actively disconnect the Wi-Fi connection with the STA.
- Wi-Fi communication Since the power consumption of Wi-Fi communication is higher than that of Bluetooth or other methods, the existing Wi-Fi connection maintenance method will generate higher power consumption.
- the AP can be a router
- the STA can be a battery-powered device with Wi-Fi functionality.
- the power consumption generated by communicating with the AP to maintain the Wi-Fi connection is an important aspect of power consumption optimization.
- the low-power Wi-Fi connection maintenance method helps improve the standby endurance of STA.
- device A and device B respectively having Wi-Fi function and Bluetooth function can establish a Wi-Fi connection by establishing a Bluetooth connection.
- device A can be a smart watch 101
- device B can be a smart phone 102
- a Bluetooth connection and/or a Wi-Fi connection can be established between the smart watch 101 and the smart phone 102.
- device A 201 has a Bluetooth module 2011 and a Wi-Fi module 2012
- device B 202 has a Bluetooth module 2021 and a Wi-Fi module 2022.
- device A 201 is an STA and device B 202 is an AP.
- the specific process of Wi-Fi communication is as follows: Device A 201 does not scan through Wi-Fi, but uses, for example, bluetooth low energy. BLE) performs Bluetooth scanning, and discovers device B 202, and then establishes a Bluetooth connection with device B 202, as shown in steps S201 and S202. Then, device A 201 and device B 202 can exchange Wi-Fi network configuration information through the established Bluetooth connection and complete network configuration, as shown in step S203. Among them, the distribution network information may include a service set identifier (SSID) of the Wi-Fi network. Afterwards, the Bluetooth connection between device A 201 and device B 202 is disconnected, and a Wi-Fi connection is established, as shown in steps S204 and S205.
- SSID service set identifier
- step S206 After device A 201 and device B 202 establish a Wi-Fi connection, service data can be transmitted through Wi-Fi. When there is no service data transmission, the Wi-Fi connection can be maintained briefly between device A 201 and device B 202, as shown in step S206.
- the Bluetooth module 2011 and the Bluetooth module 2021 participate in the execution of steps S201 to S204
- the Wi-Fi module 2012 and the Wi-Fi module 2022 participate in the execution of steps S205 and S206.
- the power consumption reduced in the existing technology is mainly the power consumption generated before the Wi-Fi connection is established.
- step S206 in Figure 2 still uses the above-mentioned existing Wi-Fi connection. The retention method will produce higher power consumption.
- the Wi-Fi connection is generally not maintained for a long time. That is to say, the method shown in Figure 2 is usually used for temporary Wi-Fi transmission services, such as point-to-point (P2P) services. Specifically, after the service data transmission is completed, the Wi-Fi connection is maintained briefly. Just disconnect, and next time new service data needs to be transmitted, execution will start from step S201 to re-establish the Wi-Fi connection. Especially in scenarios where business data is discontinuous but frequently transmitted, the existing Wi-Fi communication method shown in Figure 2 will frequently establish or disconnect Wi-Fi, which may cause large transmission delays and unstable transmission. question.

本申请涉及通信领域,尤其涉及短距离无线通信方法、装置及系统。
在例如2.4GHz频段上传输同样的数据包,采用无线局域网(wireless fidelity,Wi-Fi)通信的功耗比采用蓝牙或其他方式通信的功耗更高。
为了降低Wi-Fi通信过程中产生的功耗,现有的技术方案设计主要针对的是建立Wi-Fi连接之前,特别是Wi-Fi发现和配网的过程。但是,在Wi-Fi连接建立之后,采用现有技术仍然会产生较高的功耗。
发明内容
本申请实施例提供短距离无线通信方法、装置及系统,用于降低Wi-Fi通信过程中产生的功耗。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供了一种短距离无线通信方法,执行该短距离无线通信方法的装置可以为第一设备,可以为应用于第一设备中的模块,例如芯片或芯片系统。下面以执行主体为第一设备为例进行描述。第一设备与第二设备之间采用第一通信方式传输第一业务数据包;该第一设备采用第二通信方式向该第二设备发送第一数据包,其中,该第一数据包用于维持该第一通信方式对应的第一通信链路和该第二通信方式对应的第二通信链路;在传输相同数据包的情况下,采用该第一通信方式产生的功耗高于采用该第二通信方式产生的功耗。
在本申请实施例提供的短距离无线通信方法中,由于在第一设备或第二设备内部,第二通信方式对应的功能模块可以与第一通信方式对应的功能模块通信,因此,通过第二通信方式传输的第一数据包除了可以用于维持第二通信方式对应的第二通信链路之外,还可以用于维持第一通信方式对应的第一通信链路。采用比第一通信方式的功耗更低的第二通信方式来维持第一通信方式对应的第一通信链路,能够达到降低功耗的技术效果。进一步地,由于本申请实施例提供的短距离无线通信方法可以以较低的功耗来维持第一通信链路,因此,可以长时间地维持第一通信链路,在下一次需要采用第一通信方式传输新的业务数据包时,不需要重新建立第一通信链路,从而能够降低新业务数据包的传输时延,并且能够实现稳定的第一通信链路保持。

在本申请实施例中,“维持Wi-Fi链接”与“保持Wi-Fi连接”的含义相同,所指含义包括Wi-Fi通信下,通信设备感知对端通信设备处于上电状态且通信双方之间的距离在有效的通信范围内。“工作状态”是指通信设备传输业务数据包的状态,“睡眠状态”是相对于“工作状态”而言的、没有业务数据包传输的状态,也可以被称为待机状态。无论“睡眠状态”还是“工作状态”,都需要通信设备中相关功能模块处于上电状态。在此统一说明,以下不再赘述。为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
第一,现有的Wi-Fi连接保持方法。
一方面,接入点(access point,AP)周期性地通过Wi-Fi链路向站点(station,STA)发送信标(beacon)帧。相应地,STA通过Wi-Fi链路接收到来自AP的信标帧,表明AP处于上电状态且AP与STA之间的距离在有效的通信范围内。从而STA知晓与AP的Wi-Fi链路未断开。
另一方面,STA周期性地通过Wi-Fi链路向AP发送保持存活(keepalive)帧。其中,保持存活帧的发送周期通常为信标帧的发送周期的整数倍,保持存活帧中不携带数据。相应地,AP通过Wi-Fi链路接收到来自STA的信标帧,表明STA处于上电状态且STA与AP之间的距离在有效的通信范围内。从而AP不会主动断开与STA的Wi-Fi连接。
由于采用Wi-Fi通信的功耗比采用蓝牙或其他方式通信的功耗更高,因此,现有的Wi-Fi连接保持方法会产生较高的功耗。
通常,AP可以为路由器,STA可以为由电池供电的具有Wi-Fi功能的设备。STA待机时,与AP通信以维持Wi-Fi连接所产生的功耗是功耗优化的重要方面。低功耗的Wi-Fi连接保持方法有助于提升STA的待机续航能力。
第二,现有Wi-Fi通信中降低功耗的方法。
现有技术中,分别具有Wi-Fi功能和蓝牙功能的设备A和设备B可以通过建立蓝牙连接来实现Wi-Fi连接的建立。示例性地,如图1所示,设备A可以为智能手表101,设备B可以为智能手机102,智能手表101和智能手机102之间可以建立蓝牙连接和/或Wi-Fi连接。进一步地,如图2所示,设备A 201具有蓝牙模块2011和Wi-Fi模块2012,设备B 202具有蓝牙模块2021和Wi-Fi模块2022。假设设备A 201为STA,设备B 202为AP,结合图2,Wi-Fi通信的具体过程如下:设备A 201不通过Wi-Fi进行扫描,而是采用例如低功耗蓝牙(bluetooth low energy,BLE)进行蓝牙扫描,并发现设备B 202,进而与设备B 202建立蓝牙连接,如步骤S201和步骤S202所示。然后,设备A 201和设备B 202可以通过已建立的蓝牙连接交换Wi-Fi的配网信息,并完成配网,如步骤S203所示。其中,配网信息可以包括Wi-Fi网络的服务集标识(service set identifier,SSID)。之后,设备A 201与设备B 202之间的蓝牙连接断开,并建立Wi-Fi连接,如步骤S204和S205所示。设备A 201与设备B 202建立Wi-Fi连接之后,便可以通过Wi-Fi传输业务数据。当无业务数据传输时,设备A 201与设备B 202之间可以短暂地保持Wi-Fi连接,如步骤S206所示。其中,蓝牙模块2011和蓝牙模块2021参与步骤S201至步骤S204的执行,Wi-Fi模块2012和Wi-Fi模块2022参与步骤S205和步骤S206的执行。
然而,现有技术中降低的功耗主要是建立Wi-Fi连接之前所产生的功耗,但在Wi-Fi连接建立之后,例如图2中的步骤S206仍然沿用上述现有的Wi-Fi连接保持方法,会产生较高的功耗。
此外,由于图2中步骤S206所产生的功耗较高,因此,一般不会长时间地保持Wi-Fi连接。也就是说,图2所示的方法通常用于临时的Wi-Fi传输业务,例如点对点(point to point,P2P)业务,具体地,在业务数据传输完成之后,短暂地保持Wi-Fi连接后就断开,下次需要传输新的业务数据时再从步骤S201开始执行,以重新建立Wi-Fi连接。尤其在业务数据不连续但频繁传输的场景下,图2所示的现有Wi-Fi通信方法会频繁地建立或Wi-Fi断开连接,可能会引发传输时延较大、传输不稳定的问题。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。其中,在本申请的描述中,除非另有说明,“/”表示前后关联的对象是一种“或”的关系,例如,A/B可以表示A或B;本申请中的“和/或”仅仅是一种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。并且,在本申请的描述中,除非另有说明,“多个”是指两个或多于两个。“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-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。同时,在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“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它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,便于理解。

可选的,本申请实施例中的第一设备或者第二设备的相关功能可以由一个设备实现,也可以由多个设备共同实现,还可以是由一个设备内的一个或多个功能模块实现,本申请实施例对此不作具体限定。可以理解的是,上述功能既可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能,或者是硬件与软件的结合,或者是平台(例如,云平台)上实例化的虚拟化功能。

存储器403可以是具有存储功能的装置。例如可以是只读存储器(read-only memory,ROM)或可存储静态信息和指令的其他类型的静态存储设备,随机存取存储器(random access memory,RAM)或者可存储信息和指令的其他类型的动态存储设备,也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory,EEPROM)、只读光盘(compact disc read-only memory,CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质,但不限于此。存储器可以是独立存在,通过通信线路402与处理器相连接。存储器也可以和处理器集成在一起。
其中,存储器403用于存储执行本申请方案的计算机执行指令,并由处理器401来控制执行。处理器401用于执行存储器403中存储的计算机执行指令,从而实现本申请实施例中提供的短距离无线通信方法。

下面将结合图1至图4对本申请实施例提供的短距离无线通信方法进行具体阐述。
如图5所示,为本申请实施例提供的一种短距离无线通信方法,包括如下步骤:
步骤S501、第一设备与第二设备之间采用第一通信方式传输第一业务数据包。
在本申请实施例中,第一设备可以为STA,第二设备可以为AP;或者,第一设备可以为AP,第二设备可以为STA,本申请实施例对此不作任何限定。
示例性地,第一通信方式可以为Wi-Fi通信。相应地,第一业务数据包可以为Wi-Fi数据包。
步骤S502、第一设备采用第二通信方式向第二设备发送第一数据包。其中,第一数据包用于维持第一通信方式对应的第一通信链路和第二通信方式对应的第二通信链路;在传输相同数据包的情况下,采用第一通信方式产生的功耗高于采用第二通信方式产生的功耗。相应地,第二设备采用第二通信方式接收来自第一设备的第一数据包。
在本申请实施例中,第一数据包,第二数据包或第三数据包可以为空数据包,广播数据包,探测数据包,或者任何能够用于维持通信链路的数据包,本申请实施例对此不作任何限定。
示例性地,第二通信方式可以为蓝牙通信,例如BLE通信。结合图3,图6示出了本申请实施例提供的一种通信系统30的具体示例。其中,第一设备301具有蓝牙模块3011和Wi-Fi模块3012,第二设备302具有蓝牙模块3021和Wi-Fi模块3022。蓝牙模块3011与蓝牙模块3021之间可以按照对应的蓝牙通信协议进行通信,Wi-Fi模块3012与Wi-Fi模块3022之间可以按照Wi-Fi通信协议进行通信,并且在传输相同数据包的情况下,Wi-Fi模块3012与Wi-Fi模块3022之间通信产生的功耗高于蓝牙模块3011与蓝牙模块3021之间通信产生的功耗。在设备的内部,各模块之间也可以进行快速的信息交互,即蓝牙模块3011与Wi-Fi模块3012之间可以通信,蓝牙模块3021与Wi-Fi模块 3022之间可以通信,以例如实现模块唤醒的功能。
在本申请实施例中,第二设备能够采用第二通信方式接收到来自第一设备的第一数据包,从而第二设备可以得知在第二通信方式下,第一设备处于上电状态且第一设备与第二设备之间的距离在有效的通信范围内。也就是说,第一数据包用于维持第二通信方式对应的第二通信链路。此外,在第二设备内部,第二通信方式对应的功能模块还可以与第一通信方式对应的功能模块通信,从而第二设备中第一通信方式对应的功能模块可以得知在第一通信方式下,第一设备处于上电状态且第一设备与第二设备之间的距离在有效的通信范围内。也就是说,第一数据包还可以用于维持第一通信方式对应的第一通信链路。当第一通信方式下需要密钥更新或时钟同步时,第一设备与第二设备之间也可以采用第二通信方式传输携带相关信息的数据包,以维持第一通信链路。本申请实施例对此不作任何限定。
在本申请实施例提供的短距离无线通信方法中,由于在第一设备或第二设备内部,第二通信方式对应的功能模块可以与第一通信方式对应的功能模块通信,因此,通过第二通信方式传输的第一数据包除了可以用于维持第二通信方式对应的第二通信链路之外,还可以用于维持第一通信方式对应的第一通信链路。采用比第一通信方式的功耗更低的第二通信方式来维持第一通信方式对应的第一通信链路,能够达到降低功耗的技术效果。进一步地,由于本申请实施例提供的短距离无线通信方法可以以较低的功耗来维持第一通信链路,因此,可以长时间地维持第一通信链路,在下一次需要采用第一通信方式传输新的业务数据包时,不需要重新建立第一通信链路,从而能够降低新业务数据包的传输时延,并且能够实现稳定的第一通信链路保持。
为了进一步降低功耗,本申请实施例提供的短距离无线通信方法还包括:在第一设备与第二设备之间采用第一通信方式传输第一业务数据包的过程中,第一设备采用第二通信方式向第二设备发送第二数据包,其中,第二数据包用于维持第二通信方式对应的第二通信链路。相应地,在第一设备与第二设备之间采用第一通信方式传输第一业务数据包的过程中,第二设备采用第二通信方式接收来自第一设备的第二数据包。在该方案中,在传输第一业务数据包的过程中,通过第二数据包的传输来维持第二通信链路,从而当第一设备采用第二通信方式发送第一数据包时,不需要重新建立第二通信链路,进而能够节省因重新建立第二通信链路产生的功耗。
可选地,第一数据包的发送周期为第一周期,第二数据包的发送周期为第二周期,其中,第一周期小于第二周期。在该方案中,第二数据包的发送周期较长,能够在维持第二通信链路的前提下尽可能降低功耗。第一数据包的发送周期较短,有助于后续及时地唤醒第二设备。
在一种可能的实现方式中,在步骤S502之后,本申请实施例提供的短距离无线通信方法还包括:第一设备采用第二通信方式向第二设备发送唤醒数据包;相应地,第二设备采用第二通信方式接收来自第一设备的唤醒数据包。其中,唤醒数据包用于触发第二设备采用第一通信方式接收来自第一设备的业务数据包。之后,第一设备采用第一通信方式向第二设备发送第二业务数据包;相应地,第二设备采用第一通信方式接收来自第一设备的第二业务数据包。在该方案中,由于在第一设备或第二设备内部,第二通信方式对应的功能模块可以与第一通信方式对应的功能模块通信,因此,通过 采用第二通信方式发送唤醒数据包,第一设备可以快速唤醒第二设备中第一通信方式对应的功能模块,从而第一设备可以采用第一通信方式向第二设备发送第二业务数据包,第二设备也可以采用第一通信方式接收来自第一设备的第二业务数据包。
示例性地,在蓝牙通信协议中,第一设备向第二设备发送信号的时间点可以被称为锚点。锚点通常是周期性的且锚点的周期是可调整的。例如,在步骤S502中,第一设备采用蓝牙通信向第二设备发送的第一数据包的发送周期可以为第一周期,又例如,在第一设备与第二设备之间采用Wi-Fi通信传输第一业务数据包的过程中,第一设备采用蓝牙通信向第二设备发送的第二数据包的发送周期可以为第二周期。因此,第一设备可以在锚点采用蓝牙通信向第二设备发送唤醒数据包。也就是说,唤醒数据包的发送时刻与最近的上一个第一数据包的发送时刻之间的时长为第一周期。
示例性地,若第一通信方式下第二设备具有工作状态和睡眠状态,也就是说,第二设备可能处于睡眠状态,那么,第一设备可以尝试通过上述方法唤醒第二设备,以使第二设备从睡眠状态切换为工作状态。
在另一种可能的实现方式中,在步骤S502之后,本申请实施例提供的短距离无线通信方法还包括:第一设备采用第一通信方式向第二设备发送第二业务数据包;相应地,第二设备采用第一通信方式接收来自第一设备的第二业务数据包。
示例性地,若第一通信方式下第二设备只具有工作状态,那么,第一设备可以尝试直接采用第一通信方式向第二设备发送第二业务数据包。
为了进一步降低功耗,本申请实施例提供的短距离无线通信方法还包括:在第一设备采用第一通信方式向第二设备发送第二业务数据包的过程中,第一设备采用第二通信方式向第二设备发送第三数据包,其中,第三数据包用于维持第二通信方式对应的第二通信链路。相应地,在第一设备采用第一通信方式向第二设备发送第二业务数据包的过程中,第二设备采用第二通信方式接收来自第一设备的第三数据包。在该方案中,在传输第二业务数据包的过程中,通过第三数据包的传输来维持第二通信链路,从而后续第一设备再次采用第二通信方式发送数据包时,不需要重新建立第二通信链路,进而能够节省因重新建立第二通信链路产生的功耗。
可选地,第一数据包的发送周期为第一周期,第三数据包的发送周期为第二周期,其中,第一周期小于第二周期。在该方案中,第三数据包的发送周期较长,能够在维持第二通信链路的前提下尽可能降低功耗。第一数据包的发送周期较短,有助于后续及时地唤醒第二设备。
可选地,在第一设备与第二设备之间采用第一通信方式传输第一业务数据包的过程中,在第一通信方式对应的第一通信链路断开的情况下,第二通信方式对应的第二通信链路断开;或者,第一设备与第二设备之间采用第一通信方式传输的第一业务数据包传输完成之后且第二业务数据包传输之前,在第二通信方式对应的第二通信链路断开的情况下,第一通信方式对应的第一通信链路断开。在该方案中,第二通信链路的断开情况与第一通信链路的断开情况有关。在不需要继续维持第一通信链路或第二通信链路的情况下,将其断开,这有助于进一步降低设备的功耗。
