A time division synchronized code division multiple access system for controlling enhanced uplink random access is provided, which includes: user terminal, node B and serving wireless network controller. A method for controlling enhanced uplink random access in a time division synchronized code division multiple access system is also provided, the method includes: in high speed uplink packet access scheduling service of time division synchronized code division multiple access system, high layer of network side deploys a timer at user terminal side; if user terminal still needs to transmit data after granted available time is expired, it initiates the timer to start the delay time of enhanced uplink random accessing. According to ability of network side controlling E-DCH resources, the delay of UE initiates enhanced uplink random access after a grant is controlled, invalid random access is avoided; and reliable mechanism of enhanced uplink random access is provided. The method could utilize system resources reasonable, and improves system-working efficiency. |
