The present invention discloses a method of wideband CDMA system to reduce paging failure, configure and keep all UTRAN registration area (URA) under this RNC radio network controller RNC on whether the cross-RNC coverage area information. Serving radio network controller SRNC to URA_PCH state the user equipment UE is controlled only when there is no coverage of the coverage area across the RNC URA URA where the UE currently, the UE is allowed to move in the URA_PCH state or the URA_PCH state and remains reside in the URA. Moving the UE from the SRNC to the drift radio network controller DRNC and cross-URA, update immediately reported to the cell, perform the DSCR direct signaling connection reestablishment, the DRNC will establish a signaling connection. Both the use of the URA_PCH state UE on the network load is small advantages, but also to avoid the problem across the Iur port DSCR way paging failure.
