Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.

In actual applications, when the multicarrier configuration is all adopted in each sector of macro base station, then macro base station can be opened the carrier wave turn-off function in professional idle, so that when some carrier waves satisfy turn-off criterion, this carrier load can be moved on other carrier waves in the same coverage (being same sector), then turn-off this carrier wave to reach the energy-conservation purpose of whole net.And in the heterogeneous network of macro base station and the coexistence of little base station, if the little base station in the coverage of a certain sector of macro base station has also been opened turn-off function simultaneously, so little base station needed its load migration to macro base station before turn-offing, if and macro base station is turned off its certain one or more carrier wave already, so that the load of the residue carrier wave of macro base station is higher, and can't carry the load of little base station migration, will cause so little base station to turn-off.Under this scene, if do not take effective control measure, the carrier wave of macro base station is turn-offed and little base station produces the result who mutually suppresses between turn-offing, be unfavorable for that whole net is energy-conservation.In addition, the shutoff that refers to all carrier waves of little base station is turn-offed in said little base station in the embodiment of the invention, that is to say the invisible mode of eating dishes without rice or wine to be in of little base station.But little base station still can keep and control the communication interface between node or other base station, so that each other sending and receiving instruction.

The embodiment of the invention provides a kind of base station control method and equipment, system, can reduce whole net energy consumption.For the ease of understanding the embodiment of the invention of subsequent descriptions, the below introduces first following three kinds of relations.

The first relation: the overlapping covering relation of macro base station carrier wave and little base station.

If it is overlapping covered that a certain carrier wave F of a certain sector of macro base station and little base station B have, then between the carrier wave F of defmacro base station and the little base station B overlapping covering relation is arranged.Further, the same macro base station carrier wave of same sector can have overlapping covering relation with a plurality of little base stations, and also can there be overlapping covering relation same little base station with many carrier waves of a plurality of sectors of a plurality of macro base stations.

The second relation: the overlapping covering relation of macro base station sector and little base station.

If a certain carrier wave F and the little base station B of a certain sector S of macro base station have overlapping covering relation, then between the sector S at the carrier wave F place of defmacro base station and the little base station B overlapping covering relation is arranged.Further, can there be overlapping covering relation the same sector of macro base station with a plurality of little base stations, and also can there be overlapping covering relation same little base station with a plurality of sectors of a plurality of macro base stations.

The third relation: the overlapping covering relation of macro base station and little base station.
