Link monitoring method and device

Abstract

The invention relates to a link monitoring method and device. The method comprises the following steps: when dialing succeeds, establishing at least two links; obtaining parameter information of eachlink; determining whether a link to be restarted exists in the at least two links according to the parameter information; when it is determined that the link to be restarted exists, determining whether a restart opportunity exists currently or not; when it is determined that there is a restart opportunity at present, determining whether there is more than one communication link; and when it is determined that more than one communication link exists, restarting the link to be restarted. According to the technical scheme, the transmission of the current data can be realized, and the restart of the link with poor quality can also be realized, so that the overall quality of the link for transmitting the data is improved, and the data transmission performance of dial-up networking is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a link monitoring method and device. Background technique [0002] With the continuous development of mobile communication network technology, terminal equipment has more and more functions, and users use terminal equipment to dial up to access the Internet, which has been more and more widely used. [0003] In related technologies, a single link is usually used for dial-up Internet access, and in the process of surfing the Internet, the link needs to be monitored, that is, the downlink signal strength of a single link is detected, and when the downlink signal strength of a single link is determined to be lower than the preset When the value is set, it is determined that the link quality is poor. [0004] However, since the link is always in use, when it is determined that the quality of the link is poor, the quality of the link cannot be directly improved...

[0003] In related technologies, a single link is usually used for dial-up Internet access, and in the process of surfing the Internet, the link needs to be monitored, that is, the downlink signal strength of a single link is detected, and when the downlink signal strength of a single link is determined to be lower than the preset When the value is set, it is determined that the link quality is poor

[0004] However, since the link has been in use, when the quality of the link is determined to be poor, the quality of the link cannot be directly improved, resulting in poor data transmission performance
