Patent ID: 6987729

Claim:
In a wireless communication system having a transmitter and at least one receiver coupled via a communication channel and operable to provide a communications path for at least one user application, a method of admission control for a user requesting access to said communication system comprising the steps of: determining an allocation of system resources required to provide a predetermined level of service for a set of user applications theretofore admitted to said communication system, wherein system loading corresponding to said allocated system resources is specified in terms of a loading factor; determining a maximum loading for said system, said maximum loading being designated as a loading factor threshold; in response to an access request from a new user, determining an initial allocation of system resources needed to provide a specified level of service for said new user; computing a loading factor corresponding to system loading for system resources required for said theretofore admitted users in combination with system resources to be allocated to said new user; comparing said computed loading factor with said loading factor threshold and making an admission decision for said user requesting access based on a relationship between said computed loading factor and said loading factor threshold; wherein the step of determining an initial allocation of system resources further includes the substeps of: determining a first and a second set of performance characteristic curves based on predetermined channel condition information in respect to said communications path, said first set of performance characteristic curves being determined in respect to a user application of said requesting user and said second set of performance characteristic curves being determined in respect to a physical channel for said communications path; determining a QOS requirement for said user application; determining a set of data pairs on said first set of performance characteristic curves that correspond to said QOS requirement; mapping said determined set of data pairs on said first set of performance characteristic curves to a corresponding set of data pairs on said second set of performance characteristic curves, each said mapped data pair on said second set of performance characteristic curves being functionally related to a transmission power level in said communications channel; from said mapped data pairs on said second set of performance characteristic curves, selecting a pair corresponding to a lower transmission power level in said communications channel.
