<p>A call admission control process method in CDMA system comprises step: When call service make request for admission, classify the call service according to the service type, take the lowest nonzero speed for non-real time service, measure the load power on up link, down link of the cell on real time, take account of the factor of power increasing caused by the interference of multiple access and non-orthogonality on down link, estimate load power increment of the call service, control the call admission on both up link and down link in order to be suitable for the admission of asymmetric service, reduce call loss ratio (block probability) and improve system running efficiency on condition of system stabilization.</p> |
