Document Type and Number:
WIPO Patent Application WO/2023/071561
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of communications. Provided are a radio link failure processing method, and a terminal, a base station, a system, a device and a medium. The method comprises: when a radio link failure occurs between a terminal and a first radio access network node, recording, in a radio link failure report, radio link failure information in all carrier frequency point number ranges which are supported by the first radio access network node, and switching to a second radio access network node; the second radio access network node sending a terminal information request message to the terminal, and receiving a terminal information response message which is returned by the terminal and includes the radio link failure report of all the carrier frequency point number ranges; the second radio access network node sending, to the first radio access network node, a radio link failure indication message which includes the radio link failure report of all the carrier frequency point number ranges; and the first radio access network node adjusting switching parameters of all the carrier frequency point number ranges that are set by the first radio access network node.
