Abstract

The invention discloses a data link establishment method and device, belonging to the technical field of communications. The method comprises the following steps: enabling a network camera to receivea network access mode negotiation request sent by the terminal through the first data link, wherein the network access mode negotiation request comprises indication information of a service scene; andaccording to each network access mode currently supported by the network camera, negotiating a target network access mode used in a corresponding service scene with the terminal through the first data link, and if it is determined that the target network access mode is not matched with the first data link, establishing a second data link with the terminal according to the target network access mode, so that the network camera can switch the data link between the network camera and the terminal according to the service scene, and does not use one data link to transmit the service data with theterminal in all service scenes any more, and thus, the data transmission performance of the network camera can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for establishing a data link. Background technique [0002] Network camera, also known as Internet Protocol Camera (IPC), is a new generation of camera produced by combining camera and network technology. It can remotely transmit business data through the network. [0003] In practical application, if the user wants to access the business data in the network camera through the terminal, he needs to manually select the network access mode of the terminal first, and then the terminal establishes a data link with the network camera according to the network access mode selected by the user, and then passes the established The data link obtains the service data in the network camera. If the user does not manually switch the network access mode of the terminal, the terminal and the network camera will always use this data link to transmit busin...
