Problems solved by technology

[0005] 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

Embodiment Construction

[0024] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] In the technical solution provided by the embodiment of the present invention, when the WiMo transmission is not started, the sending end performs a conventional WiFi network search, 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 respond...

Abstract

The invention discloses a data transmission method, device and system. The method comprises the following steps: a transmitting end conveys WiMo (Wireless Mobile Multimedia Transmitting) data and wireless fidelity WiFi (Wireless Fidelity) data to a mobile terminal wireless multimedia to carry out hybrid coding; the coding data obtained by the hybrid coding is sent to a receiving end; the receiving end decodes from the received coding data; the WiMo data and the WiFi data are separated; and the WiFi data is forwarded to a next-hop route. According to the data transmission method, the WiMo data and the WiFi data can be simultaneously transmitted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device and system. Background technique [0002] 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 ...
