RESOURCE RELOCATION METHOD, BASE STATION, AND RADIO NETWORK CONTROL DEVICE

摘要

In a base station having a card for performing a plurality of a base band signal processes under a traffic consisting of a plurality of types of call and changing with time, it is possible to effectively allocate resources without generating a call loss. There are provided a signal processing card for performing a base band process and the like, radio resource monitoring means for monitoring the state of the signal processing card, radio resource control means for performing resource allocation and movement of the signal processing card, and traffic recording means for recording a traffic generated for each time band. A threshold value of the number of empty resources is decided from the calls to be contained as many as possible. When the number of empty resources in the base station has become smaller than the threshold value, a relocation process is started. Furthermore, by changing the threshold value according to the number of necessary resources of the call having the largest incidence rate for each time band, it is possible to prevent a call loss when containing the call of the largest incidence rate for each time band.
