技术领域technical field

本发明涉及通信技术领域，特别是涉及一种数据传输方法、装置和系统。The present invention relates to the field of communication technology, in particular to a data transmission method, device and system.

背景技术Background technique

WiMo(Wireless Mobile Multimedia Transmission，移动终端无线多媒体传送)技术是针对移动终端的点对点无线传输音视频的标准，可实现移动终端与家庭电视、投影设备和显示设备的多屏共享互动，实现以移动终端为中心的“三屏合一”业务体验。WiMo技术不仅具有优异的信号覆盖范围与传输率，同时可满足以手机为代表的嵌入式产品对低功耗、低时延的要求。通过使用WiMo技术，解决了无线传送高清晰音视频的难题，建立了手机等移动终端与电视屏幕等大屏幕显示设备之间的桥梁，提升了用户使用移动终端的体验，并将打破移动终端应用在家庭中使用机率较小的局面，提升了移动终端应用在家庭中使用的次数与时长。WiMo (Wireless Mobile Multimedia Transmission, mobile terminal wireless multimedia transmission) technology is a standard for point-to-point wireless audio and video transmission for mobile terminals. Centered on the "three screens in one" business experience. WiMo technology not only has excellent signal coverage and transmission rate, but also can meet the requirements of low power consumption and low delay for embedded products represented by mobile phones. Through the use of WiMo technology, the problem of wireless transmission of high-definition audio and video is solved, and a bridge between mobile terminals such as mobile phones and large-screen display devices such as TV screens is established, which improves the user experience of using mobile terminals and will break the mobile terminal application The situation that the probability of using it in the family is small increases the frequency and duration of the use of mobile terminal applications in the family.

为了保证互联互通性、降低设备成本以及充分复用现有的WiFi(WirelessFidelity，无线保真)基础设施，WiMo协议在底层复用WiFi MAC(Media AccessControl，媒体接入控制)层及以下协议，如图1所示。在WiMo场景下，移动终端作为WiMo发送端，而电视机及其WiMo附属设备作为WiMo接收端，如图2所示，移动终端中的WiMo模块通过与AP(Access Point，接入点)的连接获取同屏数据，将同屏数据编码成WiMo数据并通过WiFi模块发送到WiMo接收端，该WiMo接收端在工作时处于WiFi接入点模式。In order to ensure interoperability, reduce equipment costs and fully reuse the existing WiFi (Wireless Fidelity, Wireless Fidelity) infrastructure, the WiMo protocol multiplexes the WiFi MAC (Media Access Control, Media Access Control) layer and the following protocols at the bottom layer, such as Figure 1 shows. In the WiMo scenario, the mobile terminal acts as the WiMo transmitter, and the TV and its WiMo accessories act as the WiMo receiver. As shown in Figure 2, the WiMo module in the mobile terminal is connected to the AP (Access Point, access point) Obtain the same-screen data, encode the same-screen data into WiMo data and send it to the WiMo receiving end through the WiFi module. The WiMo receiving end is in the WiFi access point mode when working.

在实现本发明的过程中，发明人发现现有技术至少存在如下问题：In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:

由于同一个WiFi客户端无法同时连接到两个AP，无法同时保持两个WiFi网络连接并存，因此，当移动终端通过AP进行WiMo传输时，如果该移动终端需要连接普通的WiFi的AP以访问互联网，必须断开当前的WiMo传输，导致移动终端无法同时传输WiFi数据和WiMo数据。Since the same WiFi client cannot connect to two APs at the same time, it cannot maintain two WiFi network connections at the same time. Therefore, when the mobile terminal performs WiMo transmission through the AP, if the mobile terminal needs to connect to an ordinary WiFi AP to access the Internet , the current WiMo transmission must be disconnected, so that the mobile terminal cannot transmit WiFi data and WiMo data at the same time.

本发明实施例提供的技术方案中，当未启动WiMo传输时，发送端执行常规的WiFi搜网，与搜索到的WiFi AP建立连接。当启动WiMo传输时，发送端按照预设参数与接收端进行配对连接，具体地，发送端向接收端发送WiFi连接请求，接收端响应接收到的连接请求，与发送端建立快速配对。In the technical solution provided by the embodiment of the present invention, when the WiMo transmission is not started, the sending end executes a conventional WiFi search network, and establishes a connection with the searched WiFi AP. When WiMo transmission is started, the sending end performs a pairing connection with the receiving end according to preset parameters. Specifically, the sending end sends a WiFi connection request to the receiving end, and the receiving end responds to the received connection request to establish a fast pairing with the sending end.

发送端与接收端连接后，可以向接收端发送参数配置消息；接收端可以根据接收到的参数配置消息配置或修改下一跳路由的指向参数，以连接到下一跳路由，该下一跳路由用于传输WiFi数据到互联网络。发送端与接收端连接成功后，可以进行数据传输，如图3所示，包括以下步骤：After the sender is connected to the receiver, it can send a parameter configuration message to the receiver; the receiver can configure or modify the pointing parameters of the next-hop route according to the received parameter configuration message to connect to the next-hop route.
