Conserving the power of a node in a wireless communication system
First Claim
1. A method of reducing power consumption of a Radio Network Controller with a plurality of control units in a wireless communication system, each of the control units including one or more processors, the control units adapted to operate in an active mode or adopt a power saving mode, a first control unit operating in the active mode, the method comprising:
- measuring a degree of utilization of the first control unit;
comparing the degree of utilization of the first control unit with a first threshold;
if the degree of utilization of the first control unit is below the first threshold;
freezing the first control unit for a predetermined first period of time, wherein, during the freezing, the first control unit processes the existing requests on it and any new request to the first control unit is blocked; and
changing the mode of the first control unit to a power saving mode after the predetermined first period of time.
