First Claim
1. A remote unit for a wireless communication system (WCS), comprising:
- a plurality of communications service circuits each configured to process received respective communications signals for a respective communications service in the WCS;
at least one optical/electrical (O/E) converter configured to receive at least one downlink optical communications signal from head-end equipment and convert the at least one downlink optical communications signal into at least one downlink electrical communications signal to be communicated to at least one client device;
at least one electrical/optical (E/O) converter configured to receive at least one uplink electrical communications signal from at least one client device and convert the at least one uplink electrical communications signal to at least one uplink optical communications signal to be communicated to the head-end equipment;
a power selection circuit configured to draw power over a power input from a power supply and selectively provide the drawn power to each of the plurality of communications service circuits based on a control signal; and
a control circuit configured to;
determine power consumption of the remote unit based on the drawn power over the power input from the power supply;
determine if the power consumption of the remote unit exceeds a defined threshold power level for the remote unit;
generate the control signal to direct the power selection circuit to selectively provide the drawn power to one or more of the plurality of communications service circuits in a sequence to activate the one or more of the plurality of communications service circuits, such that the power consumption of the remote unit does not exceed the defined threshold power level;
store a communications service indicia comprised of phase indicia indicating the one or more of the plurality of communications service circuits drawing power from the power selection circuit such that the power consumption of the remote unit does not exceed the defined threshold power level;
determine the power consumption of the remote unit based on the communications service indicia;
set the phase indicia to an initial phase before generating the control signal to direct the power selection circuit to selectively provide the drawn power to the one or more of the plurality of communications service circuits;
if the phase indicia is set, generate the control signal to direct the power selection circuit to selectively provide the drawn power to the one or more of the plurality of communications service circuits such that the power consumption of the remote unit does not exceed the defined threshold power level; and
set the phase indicia based on each of the one or more of the plurality of communications service circuits drawing power from the power selection circuit.

Abstract
Selective activation of communications services on power-up of a remote unit(s) in a wireless communication system (WCS) based on power consumption is disclosed. To avoid a remote unit drawing more power than is allowed and risking shutting down all of its communications services, after a remote unit in the WCS is powered-up to start its operations, the remote unit selectively activates its different communications services. The remote unit selectively activates communications services based on the power consumption of the remote unit to avoid the remote unit drawing more power than is allowed. If activating a next communications service would cause the remote unit to draw more power than is allowed, the remote unit discontinues activating additional communications services. In this manner, the already activated communications services in the remote unit can remain operational without risking powering down of the remote unit and discontinuing all of its communications services.
