METHOD FOR DETECTING RADIO LINK FAILURE FOR TRANSMISSION OVER ENHANCED DEDICATED CHANNEL IN CELL-FACH STATE Russian patent published in 2012 - IPC H04W76/06 

Abstract RU 2441350 C1

FIELD: information technology.

SUBSTANCE: method and apparatus are used for detecting a radio link (RL) failure and a post verification process. Quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then occurrence of an RL failure is declared and transmission over the E-DCH in a cell forward access channel (CELL-FACH) state is terminated.

EFFECT: E-DCH resources are released in case of the post verification failure.
