Abstract

A wireless communication system wherein wireless infrastructure adapts access parameters and manages channel resources based on detailed reconnection information obtained from individual mobile stations. Mobile stations transmit particular reconnection attempt status information to the wireless infrastructure. The reconnection attempt status information, along with the aggregate statistics of other mobile stations, is used by the infrastructure to adapt access parameters to increase or decrease the likelihood of successful access. This allows the infrastructure to tune access parameters to particular mobile station information and it also allows the infrastructure to provide better resource management for both traffic channel assignments and access channel usage.

Claims

1. A mobile station for use in a wireless communication system comprising:

a processor that determines a reconnection parameter when a reconnection attempt is carried out;

a transceiver that transmits a connection request along with the reconnection parameter,

wherein the reconnection parameter has a reason for the reconnection attempt and a number of the reconnection attempt,

the processor determines whether the reason is a first reason or a second reason, and

the processor determines a first value for the number of reconnection attempt when the reason is the first reason and determines a second value for the number of reconnection attempt when the reason is the second reason, wherein the first value is the number of the reconnection attempt attributable to the first reason and the second value is the number of the reconnection attempt attributable to the second reason.

2. The mobile station according to claim 1, wherein the first reason is determined based on access failure.

3. The mobile station according to claim 1, wherein the second reason is determined based on an access retry.
