Background technology
For mobile communication system, the base station has occupied the overwhelming majority of mobile communication equipment power consumption.Along with mobile communication rapid development, the quantity of base station is more and more, and for energy savings, protection environment, and the energy-saving and emission-reduction of base station are seemed most important.Carrier wave shutoff technology is exactly one of important technology of base station energy-saving reduction of discharging.
Carrier wave shutoff technology is meant, when the sub-district is normally moved, if some carrier wave free time promptly do not have the user, then closes this carrier wave, realizes the purpose of energy-saving and emission-reduction.
At present, carrier Control is that the implementation method of switching carrier wave has two kinds:
Scheme one: be responsible for the switching carrier wave by the base station, promptly carrier wave turn-offs by base stations control.The base station when not having the user on detecting certain carrier wave, is turn-offed this carrier wave according to the situation that takies of real resource; When new resource need be distributed on the carrier wave that has turn-offed, the base station can be opened this carrier wave immediately.
We know that the management and the control of Radio Resource are finished by base station controller.And the base station is in order to realize the control to carrier wave, can only simply whether this carrier wave is turn-offed/opened to the free time according to carrier wave.Give such as, base station controller certain base station administration a cell configuration 3 carrier waves.Sometime wherein two carrier wave utilances approach 100%, and another carrier wave is an idle condition, the base station can be turn-offed the carrier wave that this is in idle condition immediately.If at this moment have certain user to need to insert, and need to adopt buttoned-up carrier resource, then the base station is opened buttoned-up carrier wave immediately; When user's on-hook, this carrier wave transfers idle condition again to, and this carrier wave can be closed again in the base station and then.
From the existing scheme one that realizes carrier Control, because base station itself does not manage and controls Radio Resource, to be placed on the base station to the control of carrier wave and realize, the rational division of work of on the one hand having run counter to whole system has caused system uncontrollable to base station resource; On the other hand, increased the unnecessary and unprofessional workload in base station, can only adopt simple control mode, be easy to generate ping-pong in this case, thereby increased user's access delay, influenced the normal performance of network because the base station is controlled resource.
Scheme two: by operation maintenance equipment the carrier wave of base station is carried out switching, this mode is by setting the time that carrier wave is closed and opened in advance, and should dispose the time to base station controller and base station.Wherein, carrier wave time of closing and opening is decided by the traffic situation that statistics obtains.Because the traffic situation only has statistical property, for the traffic situation in a certain moment at random, can't estimate, therefore the existing scheme two that realizes carrier Control, be easy to occur situation about not conforming to actual traffic situation, like this, when carrier wave idle and when not turn-offing, can waste Internet resources, and when having the user to insert on the carrier wave but turn-offing carrier wave, then influenced network capacity, reduce and come network performance.
