The invention provides a distributing method of uplink synchronized code, which includes setting reference for redistributing, initially configuring uplink synchronized code (SYNC_UL) for high speed uplink packet access (HSUPA) service, then redistributing SYNC_UL by radio network controller for HSUPA service according to the set reference for redistributing. The invention can improve rationalityof uplink synchronized code's distribution, reduce access collision caused by unreasonable distribution of SYNC_UL, improve access performance of the system, and bring good feeling to the user in thesame time.
