The present invention mainly comprises following content:
The wireless communication networks energy-saving scheme of group base stations control is built in energy-saving scheme one, base station.This scheme is different from following energy-saving scheme two and energy-saving scheme three, needs to set up energy-conservation group; And energy-saving scheme two and energy-saving scheme three are configured in advance good energy-conservation group directly use and get final product, need not to set up energy-conservation group.
One, the cell information that increases in existing cell information comprises: 1) the normal covering power information in sub-district is essential; 2) whether can be essential as the sign of Master sub-district; 3) the maximum covering power information in sub-district is normally optional, has only when for the sub-district that can be used as the Master sub-district, and the maximum covering power information in described sub-district is only essential; 4) cell footprint domain information is optional.Wherein, for the sub-district that can be used as the Master sub-district, below unified employing " candidate Master sub-district " is described, the reason of Miao Shuing is because of " sub-district that can be used as the Master sub-district " in the energy-saving scheme one like this, being different from the Master sub-district in energy-saving scheme two and the energy-saving scheme three, might not be Master sub-district truly; And the Master sub-district in energy-saving scheme two and the energy-saving scheme three since before being static configuration good, so can clearly know whether Master sub-district into truly at the very start, can directly use " Master sub-district " description.Relevant Master, Master dactylus can group leaders, under the management energy-conservation group.
The cell information of these increases can be by the base station of network management configuration under each sub-district, and can transmit between the base station.For instance, 1) in the LTE/LTE-A network, can pass through existing eNB configuration update message; Perhaps X2 sets up request message and X2 and sets up response message and transmit at X2 interface; 2) can transmit at the S1 interface by existing eNB configuration transmission and MME configuration message transfer; 3) also can transmit by X2 or the new requests/response messages of S1 interface, in office what is the need for of eNB is obtained these information of related cell from another eNB when wanting.
Two, set up energy-conservation group.Specifically, for the base station that comprises candidate Master sub-district, according to the normal covering power information in the sub-district of its adjacent area, cell footprint domain information, calculate with the cell footprint domain information of the maximum covering power information in the sub-district of this candidate Master sub-district, this candidate Master sub-district, if this candidate Master cell operation can cover the overlay area of this adjacent area when maximum covering power, then joining this adjacent area with this candidate Master sub-district is in energy-conservation group of Master sub-district; If this adjacent area has belonged to certain energy-conservation group then refuse.And all adjacent areas that satisfy condition are joined this energy-conservation group with same energy-conservation group teaming method.For certain candidate Master sub-district,, then do not set up energy-conservation group if when it is operated in maximum covering power, can not cover the overlay area of any adjacent area.One of them sub-district can only belong to one energy-conservation group.When hope adds certain energy-conservation group to certain sub-district, need belong to certain energy-conservation group as this sub-district and then refuse to this sub-district application.Wherein, the implication of involved here " relevant adjacent area " refers to: this adjacent area is non-candidate Master sub-district.
Three, comprise energy-conservation group base station monitors and comprise energy-conservation group traffic carrying capacity.
Four, find that when the base station that comprises energy-conservation group one or more energy-conservation groups of comprising are in normal condition and its traffic carrying capacity is lower than certain level, such as being lower than pre-set threshold value, as be lower than at 2% o'clock that designs peak traffic, the covering power of the Master sub-district in this energy-conservation group of this base station is strengthened, such as adjusting transmitting power and/or Downtilt, so that its covering radius expands the overlay area that can cover non-Master sub-district in this energy-conservation group to; And the base station under the non-Master sub-district in this energy-conservation group sends out message, notifies the corresponding non-Master of its dormancy the sub-district.
Five, find that when the base station that comprises energy-conservation group one or more energy-conservation groups of comprising are in power save mode and its traffic carrying capacity is higher than certain level, such as being higher than pre-set threshold value, as be higher than at 3% o'clock that designs peak traffic, message is sent out in base station under the non-Master sub-district in this energy-conservation group, notifies it to wake corresponding non-Master sub-district up; And the covering power of the Master sub-district in this energy-conservation group of this base station adjusted back to normal level, such as adjusting transmitting power and/or Downtilt to normal value.
Also can from the adjacent area of its adjacent area, select when further, setting up energy-conservation group in candidate Master sub-district in this energy-conservation scheme.
The wireless communication networks energy-saving scheme of energy-saving scheme two, webmaster combo base stations control.
One, good each energy-conservation group of information of webmaster configured in advance.Wherein each information of energy-conservation group comprises: the sign of this energy-conservation group of sub-district that is comprised, and which indicates is the Master sub-district; Also should be included in transmitting power and/or antenna downtilt angle information when entering power save mode for the Master sub-district, and have in the Master sub-district when a plurality of, an if zone that for example exists some sub-districts to cover, the sub-district that is fit to do the Master sub-district is a sector cell, need a plurality of sub-districts to strengthen covering power simultaneously and just can cover this monoblock zone, then specify one of them as Master sub-district with controlled function, remaining Master sub-district does not then have controlled function, is called auxilliary Master sub-district.
Two, for each energy-conservation group of information, webmaster is issued to base station under its Master sub-district that comprises with it.
Three, energy-conservation group traffic carrying capacity under this Master sub-district of base station monitors under the Master sub-district.
Four, find corresponding energy-conservation group when being in normal condition and its traffic carrying capacity and being lower than certain level when the base station under the Master sub-district, message is sent out in base station under the auxilliary Master sub-district in this energy-conservation group, the value of notifying its transmitting power that will assist the Master sub-district accordingly and/or Downtilt to transfer to appointment in the message; And the base station under the non-Master sub-district in this energy-conservation group sends out message, notifies the corresponding non-Master of its dormancy the sub-district.Wherein, when message is sent out in the base station under the auxilliary Master sub-district in this energy-conservation group, can carry transmitting power and/or the antenna downtilt angle information of corresponding auxilliary Master sub-district when entering power save mode in this message.
