Improved reliability of the radio link with the use of multi-carrier-performance in wireless broadband systems

摘要

A method for multi-carrier-switch, comprising:Connecting a user terminal user equipment (ue), wherein the ue to the communication via a plurality of carriers is configured with a base station (base station bs);Monitoring a link quality on a primary carrier, the of the ue is used, where the ue on the plurality of carriers, which runs a primary carrier and one or more secondary carrier;Detecting a deterioration of the connection quality on the primary carrier;Determining whether recovery on the primary carrier;A declared radio link failure (radio link failure, rlf) on the primary carrier, whereby the rlf of the ue is declared;Identifying of the one or more of the secondary support; selecting a secondary target carrier from the one or more of the secondary support; andSetting up of a new primary carrier on the secondary target carrier.
