Problems solved by technology

[0004] In the scenario of multi-user cooperative communication, once the wireless link of the beneficiary UE or the supporting UE fails, the T311 timer will be started, and cell reselection and wireless link re-establishment will be performed. If the link fails to be re-established successfully, the UE will enter the idle state, which will interrupt the communication of the UE and reduce the user experience

Abstract

The embodiment of the present invention discloses a method and device for processing a radio link failure, which relate to the field of communication technology. The method includes: when the first user equipment UE detects that the radio link fails, it initiates the reconstruction of the radio link; if If the wireless link re-establishment fails, the first UE sends a keep-alive packet to the second UE through a short-distance link, and the keep-alive packet includes at least keep-alive indication information for instructing the base station to retain the context of the first UE , so that the base station retains the context of the first UE according to the keep-alive indication information. The invention is suitable for multi-user cooperative communication technology.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing wireless link failure. Background technique [0002] With the rapid development of global communication technology, a variety of different mobile communication systems have emerged, for example, the Global System of Mobile communication (Global System of Mobile communication, English abbreviation is GSM) network, General Packet Radio Service technology (General Packet Radio Service) , English abbreviation is GPRS) network, wideband code division multiple access (Wideband Code Division Multiple Access, English abbreviation is WCDMA) network, CDMA-2000 network, time division synchronous code division multiple access (Time Division-Synchronous Code Division Multiple Access, English abbreviation TD-SCDMA) network, Worldwide Interoperability for Microwave Access (WiMAX) network, etc. These mobile communication systems usually provide ...
