Wireless communication system, and device and method used in same

Abstract

The present invention provides a wireless communication system, an apparatus in the wireless communication system and a method, wherein the apparatus (100) at a user equipment side in the wireless communication system comprises: a wireless link problem detection unit (102), which detects a first wireless link between a first node and a user equipment so as to determine whether a wireless link problem occurs; a timer configuration unit (104), which starts a first timer when detecting that the wireless link problem occurs on the first wireless link, wherein the user equipment considers that a wireless link failure event occurring on the first wireless link is detected when the first timer expires; and a wireless link information reporting unit (106), which reports content comprising wireless link information of the first wireless link to a second node through a second wireless link between the user equipment and the second node when detecting that the wireless link problem occurs on the first wireless link. According to the present invention, service interruption time of the user equipment can be reduced and user experience can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and more specifically, to a device, a device, a method used in the wireless communication system, and a wireless communication system on the user equipment side in a wireless communication system capable of quickly solving wireless link problems. Background technique [0002] When the signal of the user equipment is strongly interfered or deeply attenuated, the wireless link failure of the user equipment will occur. The failure of the wireless link leads to the interruption of service transmission. During this period, the user cannot send or receive any data service. Additionally, prolonged interruptions in connectivity can negatively impact the application layer, degrading the user experience. [0003] In order to cope with the exponentially increasing mobile data volume in the network, small cells are deployed in hotspot areas in heterogeneous networks. In the standard...

AI Technical Summary

Problems solved by technology

For the solution (1), it can directly reduce the overall service interruption time, but it may cause the user equipment to declare the radio link failure prematurely, that is, the user equipment loses the opportunity to wait for the radio link with the problem to recover, thus potentially increasing the service outage to some extent

For the (2) scheme, it can improve the success probability of RRC connection re-establishment, but when the user equipment context saved by the source cell changes, additional signaling overhead is required to transmit the new user equipment context, and the signaling Make the overhead proportional to the number of target cells for potential RRC connection re-establishment, and possibly introduce additional delay
