<p>A mobile communication system includes a plurality of base stations 13-16, a mobile terminal 11 and a base station controller (BSC) 12 controlling the radio resource of the base stations 13-16. The BSC 12 receives from each of the base stations 13-16 a signal 22-25 indicative of how much of the radio resource is used by each of the base stations 13-16 and data indicative of the quality of the radio channels 18-21 of the mobile terminal 11 in a macro diversity condition. When the amount of radio resource used exceeds a first threshold, the BSC 12 keeps a first number of radio channels 18-21 alive and releases the rest of the radio channels 18-21. The first number of radio channels 18-21 kept alive is a minimum number of channels 18-21 that the mobile terminal 11 is allowed to have and these are selected for having higher radio quality than the radio channels 18-21 that are released.</p> |
