Problems solved by technology

Therefore, if many terminals transmit on the access channel and / or if some terminals transmit on the access channel frequently, a heavy load on the access channel may increase the load on the system, delays required by terminals connected to the system access, etc.

Embodiment Construction

[0015] The techniques described herein may be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and others. The terms "system" and "network" are often used interchangeably. A CDMA system may implement a radio technology such as cdma2000, Universal Terrestrial Radio Access (UTRA), and so on. cdma2000 covers IS-2000, IS-95 and IS-856 standards. UTRA includes Wideband-CDMA (WCDMA) and other variations of CDMA. A TDMA system can implement a radio technology such as Global System for Mobile Communications (GSM). OFDMA systems may implement radio technologies such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM Wait. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced are the latest releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-Advanced and GSM are described in document...

Abstract

Techniques for access channel load management in a wireless communication system are described. In an aspect, the load of the access channel may be controlled by having each terminal regulates its use of the access channel (e.g., its rate of system access) based on a rate control algorithm (e.g., token bucket). The rate control algorithm may maintain information on past activities of a terminal and may regulate the use of the access channel by the terminal based on its past activities in order to control the access channel load and achieve fairness. The system may determine (312) at least one parameter value for the rate control algorithm based on load conditions and may broadcast (314) the at least one parameter value to terminals. Each terminal may regulate (318) its use of the access channel based on the at least one parameter value received from the system (316).

Description

[0001] This application claims U.S. Provisional Application No. 61 / 033,149, filed March 3, 2008, entitled "METHOD AND APPARATUS FOR LOAD MANAGEMENT IN WIRELESS COMMUNICATIONS" priority to the application assigned to the assignee of the present invention and incorporated herein by reference. technical field [0002] The present disclosure relates generally to communications, and more specifically, to techniques for managing the load of access channels in wireless communication systems. Background technique [0003] Wireless communication systems are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless systems may be multiple-access systems capable of supporting multiple users by sharing the available system resources. Examples of these multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Acc...
