METHOD OF DYNAMICALLY CONTROLLING THE LENGTH OF R_DATA MESSAGES ON A RANDOM ACCESS CHANNEL

摘要

A method for dynamically controlling the length of an R_DATA message on a random access channel (25) is disclosed. Initially, a set of threshold values for traffic load levels are established (65) with respect to the usage of a random access (RACH) channel (25). A particular R_DATA message length is then associated with each of these threshold values. The RACH channel (25) is monitored (70) to track the traffic load (50) on the RACH (25), and once one of the established threshold levels is reached (80, 95), the R_DATA message length is set to the value associated with that threshold level (85). R_DATA messages are then transmitted (90) according to the new length.
