1. A method of optimizing a data format selection procedure (E-TFC) for up link transmission between a terminal and a base station, comprising:
- optimizing the number of time slots to be used by the terminal to detect a command value transmitted from the base station to use the entire period of time Tlimit, and executing an update, wherein the base station transmits a signal including at least one repetition command to the terminal in a predetermined number of time slots, the command constructed to update at least one predetermined parameter intervening in the data format selection, and the terminal detects, on receiving the signal, the command value and conducts the update according to the detected value during a time window having a predetermined period of time Tlimit;
calculating a period of time Trg between an end of the time slots and a start of the up link transmission;
estimating a period of time Tlimit available to execute the update;
comparing the period of time Trg with the period of time Tlimit; and
reducing, if the period of time Trg is less than the period of time Tlimit, the number of time slots dedicated to the signal detection.

Abstract
The present invention relates to a method of optimizing a data format selection procedure (E-TFC) for up link communication between a terminal and a base station on a cellular communication network in which the base station transmits to the terminal a signal including at least one piece of update information of at least one predetermined parameter intervening the data format selection. The method in accordance with the present invention further includes the step of optimizing a period of time required to detect the signal transmitted from the base station.
