Abstract

The invention discloses a radio link control method and apparatus, a radio network controller (RNC) and a user equipment (UE), comprising: when the UE communicates through a first frequency point radio link in a first frequency point cell, the RNC receives measurement information about a second frequency point cell reported by the UE, wherein the second frequency point cell is a cell deployed on another frequency point within the coverage area of the first frequency point cell; and the RNC sends configuration parameters between the UE and a second frequency point radio link to the UE to instruct the UE to set up synchronization with the second frequency point radio link. As the UE is instructed to set up the synchronization with the different frequency point radio link after the measurement information of the different frequency point cell reported by the UE is received and the UE is not directly instructed to switch to the different frequency point radio link, synchronization between a macro eNB and a micro eNB can be maintained at the same time, so that different frequency cell switching failure can be effectively avoided, and continuous user experience is ensured.

For above-mentioned steps S420, in a kind of possible implementation, the second frequency step-out information can be the instruction of " the second frequency radio link failure " or " Radio Link Failure occurs the second frequency " etc.

In addition, because the first frequency point cell is current Serving cell, UE can pass through the up signaling directly sending the second frequency step-out information that carries via the first frequency wireless link, by this message notice to RNC.Such as, this up signaling can be SCRI.

Owing to maintain the synchronous of UE and the first frequency wireless link and the second frequency wireless link simultaneously, when finding that UE loses synchronous with non-communicating with the second frequency wireless link based on link signal quality, method for wireless link control according to the above embodiment of the present invention can delete the second frequency wireless link in time, and can not affect present communications the first frequency wireless link.
