Abstract
This document provides wireless communications technologies, including methods, devices and systems. For example, a method of facilitating wireless communications is provided to include operating a wireless network to receive an access probe transmission from an access terminal requesting an access channel grant; perform, based on the received access probe transmission, a persistence test with the access terminal; receive a subsequent probe transmission for the access channel grant request; and perform, based on the received subsequent probe transmission, a subsequent persistence test with the access terminal.
Claims10
A wireless communications method, comprising:
- transmitting multiple access probe transmissions from an access terminal requesting an access channel grant;
- and
- performing, prior to transmitting every one of the multiple access probe transmissions, a persistence test between two consecutive multiple access probe transmissions for controlling congestion on an access channel, so that no access probe transmission is performed without first performing the persistence test,
- wherein the performing the persistence test includes:
- comparing a random number x with a persistence number p;
- and
- deciding to transmit a corresponding access probe when the random number x is less than the persistence number p, wherein x is between 0 and 1 and p is not zero.
A wireless communications apparatus, comprising:
- a probe transmitter that transmits multiple access probe transmissions from an access terminal requesting an access channel grant;
- a persistent test performer that performs, prior to transmitting every one of the multiple access probe transmissions, a persistence test between two consecutive multiple access probe transmissions for controlling congestion on an access channel, so that no access probe transmission is performed without first performing the persistence test
- wherein the performing the persistence test includes:
- comparing a random number x with a persistence number p;
- and
- deciding to transmit a corresponding access probe when the random number x is less than the persistence number p, wherein x is between 0 and 1 and p is not zero.
A wireless communications apparatus, comprising:
- an access terminal sending multiple access probe transmissions for requesting an access channel grant, and
- performing, prior to transmitting every one of the multiple access probe transmissions, a persistence test between two consecutive multiple access probe transmissions for controlling congestion on an access channel, so that no access probe transmission is performed without first performing the persistence test,
- wherein the performing the persistence test includes:
- comparing a random number x with a persistence number p;
- and
- deciding to transmit a corresponding access probe when the random number x is less than the persistence number p, wherein x is between 0 and 1 and p is not zero.
A computer program product, comprising a computer-readable, non-volatile memory having code stored thereon, the code, when executed by a processor, causing the processor to:
- transmit multiple access probe transmissions from an access terminal requesting an access channel grant;
- and
- perform, prior to transmitting every one of the multiple access probe transmissions, a persistence test between two consecutive multiple access probe transmissions for controlling congestion on an access channel, so that no access probe transmission is performed without first performing the persistence test,
- wherein the performing the persistence test includes:
- comparing a random number x with a persistence number p;
- and
- deciding to transmit a corresponding access probe when the random number x is less than the persistence number p, wherein x is between 0 and 1 and p is not zero.
