Method of managing processing resources in a mobile radio system

Abstract

A method of managing processing resources in a mobile radio system, in which a first entity manages radio resources and corresponding processing resources, the latter being provided in a second entity separate from the first entity. The second entity signals to the first entity its global processing capacity, or capacity credit, and the consumption law, or quantity of the global processing capacity, or cost, for different spreading factor values. The first entity updates the capacity credit on the basis of the consumption law. In the case of multicode transmission using N spreading codes, the updating is effected on the basis of the cost for at least one of the N spreading codes.

1 . A load control and/or call admission control method in a mobile radio system, wherein: 
 a base station signals to a radio network control a capacity credit, and a capacity consumption law,    the radio network controller updates the capacity credit on the basis of the consumption law, and    if the capacity credit in the uplink and/or downlink direction falls below a given first threshold, any new call is rejected until the capacity credit is again above a given second threshold greater than or equal to the first threshold.    
     
     
         2 . A mobile radio system comprising 
 a base station comprising means for signaling to a radio network controller a capacity credit and a capacity consumption law,    a radio network controller comprising means for updating the capacity credit on the basis of the capacity consumption law, and    a radio network control comprising means for rejecting any new call if the uplink and/or downlink capacity credit falls below a given first threshold until the capacity credit is again above a given second threshold greater than or equal to the first threshold.    
     
     
         3 . A radio network controller comprising: 
 means for receiving from a base station a capacity credit and a capacity consumption law,    means for updating the capacity credit on the basis of the capacity consumption law, and    means for rejecting any new call if the uplink and/or downlink capacity credit falls below a given first threshold until the capacity credit is again above a given second threshold greater than or equal to the first threshold.    
     
     
         4 . A load control and/or call admission control method in a mobile radio system, wherein: 
 a base station signals to a radio network controller a capacity credit, and a capacity consumption law,    the radio network controller updates the capacity credit on the basis of the capacity consumption law, and    an overload control procedure is initiated if the capacity credit falls below a given threshold.    
     
     
         5 . A mobile radio communication system, comprising: 
 a base station comprising means for signaling to a radio network controller a capacity credit and a capacity consumption law,    a radio network controller comprising means for updating the capacity credit on the basis of the capacity consumption law, and    means for initiating an overload control procedure if the capacity credit falls below a given threshold.    
     
     
         6 . A radio network controller comprising: 
 means for receiving from a base station a capacity credit and a capacity consumption law,    means for updating the capacity credit on the basis of the capacity consumption law, and    means for initiating an overload control procedure if the capacity credit falls below a given threshold.
