Abstract

Embodiments of the invention provide a recovery method and system for wireless link failure. The method includes the following steps: if the wireless link failure is detected, the recovery method of the wireless links is determined based on a QoS net utility function, and the recovery method is a first recovery method or a second recovery method; recovery is performed on the wireless links based on the recovery method; the first recovery method is the recovery method based on connection reconstruction, and the second recovery method is the recovery method based on cover grade improving. Through the QoS net utility function of the terminal, which recovery method being used to perform recovery is determined, the optimal recovery method can be selected by the terminal to perform recovery on the wireless links, when recovery is performed on the wireless links of any terminal physical layer, the communication time-delay and the power consumption of the recovery of the wireless links are reduced, and the comprehensive benefit of the terminal is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a method and system for recovering a wireless link failure. Background technique [0002] The vigorous development of the Internet of Things technology and its wide application in the fields of smart meter reading, environmental monitoring, smart home, and industrial monitoring have attracted close attention from academia and industry. The typical application scenarios of the Internet of Things are mostly special closed spaces such as inside the car, basement, and underground. Compared with the ordinary communication environment, the indoor IoT terminal will experience severe penetration loss, which will seriously affect the communication quality of the IoT terminal. Especially in the fifth generation mobile communication system (5G, the Fifth Generation) scenario, compared with the traditional second generation (2G, the Second Gener...
