摘要:
The present invention provides a time division synchronous code division multiple access (TD-SCDMA) system for controlling enhanced uplink random access, including user equipment (UE), node B and serving radio network controller. The present invention also provides a method for controlling the enhanced uplink random access in a time division synchronous code division multiple access system, including: in high speed uplink packet access scheduling service of time division synchronous code division multiple access system, the higher layer of network side deploys a timer at the user equipment side; if the user equipment still needs to transmit data when the current available grant expires, it starts up the timer which is used as the delay time of initiating the enhanced uplink random access. According to the ability of the network side in controlling E-DCH resources, the present invention can be used to control the time delay that UE initiates the enhanced uplink random access after one grant expires, so as to avoid invalid random access; meanwhile the present invention provides a reliable mechanism for the enhanced uplink random access. By using the method of this invention, system resources can be reasonably utilized, thereby greatly improving the system efficiency.
