Problems solved by technology

However, the working mode in which the first device and the second device are successfully matched with each other and the connection is successfully established has certain randomness, and it is possible that the rate in the current matching working mode is low, which affects data transmission performance

Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than 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.

[0058] The mode adaptive matching method provided by the embodiment of the present invention is applied to the process of establishing a connection for a device supporting multiple working modes, so as to preferentially work in a high-speed working mode on the basis of realizing adaptive matching of the working mode of the device. For example: the mode adaptive matching method provided by the embodiment of the present invention can be ap...

Abstract

The invention provides an adaptive mode matching method and device. The adaptive mode matching method provided by the invention comprises the following steps: after a first device is successfully connected with a second device in a first working mode, if the rate in the first working mode is greater than or equal to a set threshold, then keeping the first working mode, and stopping switching the working mode; and otherwise, switching the working mode according to a sequence of rates from high to low, and if the first device is successfully connected with the second device in the current working mode in a switching process, keeping the current working mode, and stopping switching the working mode. After the first device is successfully connected with the second device, if the first device judges the rate in the successfully connected working mode is smaller than the set threshold, the first device switches the working mode according to the sequence of rates from high to low so as to connect with the second device in the high-rate working mode, and thus data transmission is preferably performed in the high-rate working mode on the basis of realizing the adaptive matching of the working mode.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mode adaptive matching method and equipment. Background technique [0002] In the prior art, various interface chips may be disposed inside the electronic device, therefore, the electronic device may support multiple interface modes. When establishing a connection between different devices, pattern matching is required. [0003] For adaptive matching of different rates on the same medium, for example, ordinary network physical layer (PHY) chips support 10\100\1000Base-T, the specific method is: use different data transmission auto-negotiation signals for pre-negotiation , the pulse mode adopted by this negotiation signal is different from data transmission. Only when the negotiation pulse informs each other of the modes supported by each other can it decide which interface mode to use for data transmission for adaptive matching. [0004] For interface modes of ...
