Method of determining transmission rate from a mobile station to a base station in a wireless communication system
First Claim
1. A method for determining when a request for higher transmission rate should be granted to a mobile station that has access to a communication system comprising the steps of:
- calculating a first indicator using a second indicator, for all active connections;
deciding whether to grant the mobile station access to use the requested higher transmission rate based on a comparison of at least one of the first indicator and the second indicator relative to at least one blocking threshold;
tracking at least one of the indicators, if the mobile station is granted access to use the requested higher transmission rate, prior to transmissions by the mobile station at the higher transmission rate; and
deciding whether to deny the mobile station access to use the requested higher transmission rate based on a comparison of the at least one tracked indicator to the at least one blocking threshold.

Abstract
A method is disclosed for determining when a request for a higher transmission rate should be granted to a mobile station that currently has access to a communication system to facilitate the maintenance of a performance target (quality of service level) of the reverse link. The method for determining when a mobile station can have access to a higher transmission rate includes obtaining first and second estimated performance indicators for a reverse link of the base station that a mobile station is currently accessing. A blocking threshold value is established. Access at the requested higher transmission rate is based on a comparison of the first and second indicators relative to the established blocking threshold value. If access is denied at the requested higher rate, access will be granted at the next lower rate which will not degrade the performance of the wireless communication system.

12. A method for determining when a request for higher transmission rate should be granted to a mobile station that has access to a communication system comprising:
-
obtaining a fit estimated performance indicator and a second estimated performance indicator for all active connections; establishing a blocking threshold; and deciding whether to grant or deny the mobile station access to use the requested higher transmission rate based on a comparison of the first and second indicators relative to the established blocking threshold, wherein the deciding step comprises denying access at the requested higher transmission rate to the mobile station when the first performance indicator exceeds the blocking threshold value to avoid degradation of performance of the wireless communication system, wherein the obtaining step comprises obtaining a projected receive signal strength indicator rise as the first estimated performance indicator and estimated loading as the second indicator, the projected receive signal strength indicator rise being a ratio of the estimated receive signal strength indicator at the start time to one minus the projected change of loading for the mobile station requesting the new channel divided by one minus the estimated loading. - View Dependent Claims (13, 14, 15, 16)

17. A method of communicating with a mobile station over a network cannel, the method comprising the steps of:
-
determining whether to grant the mobile station access to a transmission rate higher than a current transmission rate of the mobile station, based on a comparison of at least one channel indicator to at least one blocking threshold; trading the at least one channel indicator, if the mobile station is granted access to the higher transmission rate, prior to transmissions by the mobile station at the higher transmission rate; and determining whether to deny the mobile station access to the higher transmission rate based on a comparison of the at least one tracked channel indicator to the at least one blocking threshold. - View Dependent Claims (18, 19, 20)
