Title:
A TD-SCDMA SYSTEM AND A METHOD FOR CONTROLLING HSUPA RANDOM ACCESS THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/025233
Kind Code:
A1
Abstract:
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.
