Problems solved by technology

This results in a reduction in the receive capacity of the reverse link
[0024] Furthermore, since the accuracy of ROT measured by the base station of the current mobile communication system such as the 1xEV-DO system is not yet reliable, the related art method of setting the RAB simply by comparing the measured ROT value with the reference value ROTm_th has various advantages in many respects. a limitation

Embodiment Construction

[0049] Referring to FIG. 1, the base station measures the ROTm value at predetermined time intervals, such as time slot units (S11). ROTm is a measurement value used to determine the reverse link load state, and is obtained by subtracting (db principle) thermal noise power (RxPower_Thermal) from the total received power RxPower_Total received by the antenna at the receiving end of the base station. ROTm is measured by the RF device in the base station.

[0050] ROTm is compared with the reference value ROTm_th (S12). If ROTm is higher than ROTm_th, the reverse active bit (RAB) (ie, RAB=1) is set based on reducing the terminal transmission data rate (S18). If ROTm is smaller than ROTm_th, for example, the RAB setting time (RABSetTime) is calculated.

[0051] After the RAB setting time corresponding to the ROTm state and the RAB setting time corresponding to the ROTm state transition degree are set in advance, the RAB setting time is calculated whenever the ROTm state changes. For e...

Abstract

In a mobile communication system, a method of setting a reverse activity bit (RAB) is provided. The method comprises measuring a rise over thermal noise-measured (ROTm) representing a load degree of a reverse link; comparing the ROTm with a setup reference value (ROTm_th); setting the RAB to lower data rate of a terminal, when the ROTm is greater than the ROTm_th; enabling a base station to receive and monitor a variation state of the ROTm, when the ROTm is less than the ROTm_th; and setting the RAB to control the data rate according to the variation state of the ROTm.

Description

[0001] Cross-reference related applications [0002] This application claims the priority of Korean application No. 10-2002-0078797 filed on December 11, 2002 and Korean application No. 10-2002-79101 filed on December 12, 2002, and their entire contents are hereby combined as reference. Technical field [0003] The present invention relates to a method for setting a reverse activation bit in a mobile communication environment, and in particular, to a method for setting a reverse activation bit for enabling users in a cell or sector to receive services and enhancing reverse link capacity. Background technique [0004] Generally, 1xEV-DO is a dedicated data communication system developed by Qualcomm in the late 1990s to provide general data communication services in a non-real-time wireless mobile environment. The 1xEV-DO system adopts an inherent resource allocation method corresponding to the characteristics of the forward and reverse links. [0005] In the forward link, the base ...
