Embodiment
Base station equipment is undertaken the requirement of work and the business that guarantees to provide good down of state that sub-district as much as possible is in low-power consumption.The current traffic carrying capacity of dynamic analysis provides enough sub-districts in this programme, lets a part of sub-district get into power save mode; When traffic carrying capacity increases, but dynamic wake-up is in the sub-district of power save mode, until all being in normal operating conditions; When traffic carrying capacity reduces, can dynamically the part sub-district be changed over to energy-conservationly again, up to having only minimum sub-district that the most basic access service is provided, require any zone can not be simultaneously because of energy-conservation and take place to cover the cavity.
As shown in Figure 1, the base station energy-saving method comprises in this programme: after the abutting subdistrict of Target cell satisfied request energy saving condition and said Target cell all satisfied the energy-conservation condition of the said Target cell of permission, said Target cell was set to power save mode.
Wherein, Target cell is meant non-basic coverage cell, and the abutting subdistrict of said Target cell is meant the sub-district of having set up syntople with said Target cell.Energy-conserving action is mainly played in the effect of non-basic coverage cell, and the effect of basic coverage cell mainly is the effective covering that guarantees signal.Basic coverage cell is meant the sub-district in the minimum sub-district that can cover predeterminable area, and non-basic coverage cell is meant other sub-district except that said basic coverage cell on the said predeterminable area.The purpose of this kind setting is: when the traffic carrying capacity of non-basic coverage cell seldom the time, then change maximum non-basic coverage cell over to power save mode as far as possible, be in low power mode of operation; Basic coverage cell then provides effective covering of this regional signal, ensures signal quality, and when traffic carrying capacity increases, wakes the sub-district that is in power save mode up.
The method of confirming basic coverage cell and non-basic coverage cell is: determine basic coverage cell and non-basic coverage cell according to the accurate coverage of sub-district and the syntople of minizone.Method according to the accurate coverage of confirming the sub-district is: confirm the rough coverage of sub-district according to sub-district longitude and latitude, cell transmit power, antenna in cell deflection and antenna in cell angle of declination, according to the position coordinates that accesses terminal the rough coverage in said sub-district is done the border and revise the accurate coverage that obtains the sub-district.
When Target cell and its abutting subdistrict all belonged to same base station, this base station can be accomplished the abutting subdistrict whether Target cell satisfy request energy saving condition and said Target cell at inside of base station and whether satisfied the judgement that allows the energy-conservation condition of said Target cell.When Target cell all belongs to different base station with its abutting subdistrict; Need carry out information interaction between the base station; Interaction content is the information of minizone, and said Target cell sends energy-conservation request to said abutting subdistrict after satisfying the request energy saving condition; After said abutting subdistrict satisfies the energy-conservation condition of the said Target cell of permission, allow the energy-conservation message of said Target cell to said Target cell notice.
The traffic carrying capacity that the described request energy saving condition is meant said Target cell less than the lasting duration of first traffic volume threshold greater than the first preset duration; The traffic carrying capacity that said permission energy saving condition is meant all of its neighbor sub-district less than the lasting duration of second traffic volume threshold greater than the second preset duration.
Abutting subdistrict satisfies when stopping the energy-conservation condition of said Target cell, sends to said Target cell and wakes power-saving notification up, and said Target cell withdraws from power save mode.
The sub-district of long-term work possibly occur failing and be wrong, is more serious and this failure is arranged with mistake.Basic coverage cell is responsible for the basic covering in this zone, and their existence can make basic coverage cell get into and withdraw from power save mode smoothly; If yet coverage cell breaks down basically, need to confirm again basic coverage cell collection.Consider and confirm that the basic algorithm that covers is general more consuming time; The situation that this programme breaks down basic coverage cell is divided into two kinds: (or a small amount of) sub-district moves back clothes and clothes are moved back in a plurality of (or in a large number) sub-district; And carry out the processing of corresponding network self-healing: in order to tackle the clothes situation of moving back; In this programme, occur one in the said abutting subdistrict when moving back clothes, wake the sub-district that is in power save mode in the neighbor cell of said abutting subdistrict up; Occur a plurality ofly when moving back clothes in the said abutting subdistrict, wake that all are in the sub-district of power save mode in the operation maintenance center compass of competency under the said Target cell up.
The base station energy-saving system comprises base station energy-saving device and OMC in this programme.
