Network switching method and terminal device

Abstract

The invention discloses a network switching method and a terminal device, and the method can enable the terminal device accessed to a 5G system to be switched to other non-5G systems in time when thedata link quality is poor, so as to guarantee the continuity of data services, and improve the terminal performance and user experience. The method comprises the following steps: the terminal device firstly acquiring a link quality parameter of a data link of the terminal device, and when the number of downlink data packets received by the terminal device exceeds a first threshold value and the number of sent uplink data packets is zero within a set time length, or when the number of the uplink data packets sent by the terminal device exceeds a second threshold and the number of the received downlink data packets is zero within the set duration, determining that the 5G system is unavailable and switching from the 5G system to a non-5G system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a network switching method and terminal equipment. Background technique [0002] With the progress of communication technology, the fifth generation (5th Generation, 5G) system (such as new generation radio access technology (new radio access technology, NR)) will be the mainstream communication technology for a period of time in the future. The 5G system cannot meet the coverage requirements in the early stage of commercial use, so the terminal equipment connected to the 5G system will have the problem of poor link quality of the data link. For example, the access request sent by the application running on the terminal device may not receive feedback within a period of time, resulting in access failure. [0003] At present, although a terminal device loaded with the Android system has the above-mentioned problems, it can use the self-healing (dorecovery) ...

Problems solved by technology

The 5G system cannot meet the coverage requirements in the early stage of commercial use, so the terminal equipment connected to the 5G system will have the problem of poor link quality of the data link

For example, the access request sent by the application running on the terminal device may not receive feedback for a period of time, resulting in the problem of access failure

[0003] At present, although a terminal device loaded with the Android system has the above-mentioned problems, it can use the self-healing (dorecovery) mechanism supported by the Android system (including the self-healing mechanism and four-level reconstruction strategy, respectively querying the activation list, resetting Routing, re-registration, switching flight mode, etc.) to perform self-healing, but this self-healing mechanism often cannot solve the problem of poor link quality, which may cause users to freeze and respond slowly when using 5G terminal devices to access the Internet. question
