Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As it is shown in figure 1, the system architecture schematic diagram being suitable for for the embodiment of the present invention. Local controller and multiple Smallcell are by IP (InternetProtocol, the agreement of interconnection between network) net is attached, local controller issues control command can to each Smallcell, so that Smallcell performs the order received.
As in figure 2 it is shown, the Smallcell power-economizing method that the embodiment of the present invention provides, including:
Step 201, according to the energy saving period in power save parameters corresponding for Smallcell, it is judged that whether described Smallcell is in described energy saving period;
If the described Smallcell of step 202 is in described energy saving period, then according to the energy conservation starting thresholding in described power save parameters, it is judged that whether described Smallcell meets energy saving condition;
If the described Smallcell of step 203 meets energy saving condition, then according to the Energy Saving Strategy in described power save parameters, generate radio-frequency channel shutdown command and be sent to described Smallcell, so that described Smallcell is according to the shutdown command of described radio-frequency channel, close the radio-frequency channel in described Smallcell.
Attendant is installed in local controller, according to each Smallcell overlay area characteristic, corresponding power save parameters is configured for each Smallcell, after Smallcell is successfully accessed to local controller, local controller is according to the power save parameters corresponding for each Smallcell of storage in local controller, Smallcell is controlled, wherein, power save parameters corresponding for each Smallcell includes energy saving period, energy conservation starting thresholding (energy conservation starting thresholding comprises again number of users thresholding and downlink resource occupancy thresholding), energy-conservation closedown thresholding and Energy Saving Strategy etc.
Energy saving period is used for indicating Smallcell relatively idle within which time period, the region that each Smallcell covers is different, the intraday business of zones of different changes very greatly, Annual distribution has very strong regularity: such as residential quarter portfolio on daytime is little, and the time period portfolio in morning to morning is less; Such as office building the week portfolio on daytime is very big, and smaller with the portfolio at weekend at night; Such as dining room noon and dusk portfolio are relatively larger, and section business amount is less At All Other Times. For example, such as a Smallcell overlay area is dining room, then energy saving period corresponding for this Smallcell can be set as 00:00～10:00, a Smallcell overlay area is office building for another example, then energy saving period corresponding for Smallcell can be set as Monday～Friday 18:00-09:00 and weekend whole day, etc. Specifically, an energy saving period corresponding for Smallcell, is that the traffic characteristics according to this Smallcell region covered sets.
Energy conservation starting thresholding is used for judging whether Smallcell meets energy saving condition, wherein comprises again number of users thresholding and downlink resource occupancy thresholding.
Energy-conservation closedown thresholding is used for judging whether Smallcell meets energy-conservation closedown condition.
Energy Saving Strategy closes for indicating or opens which radio-frequency channel of Smallcell.
In an initial condition, all radio-frequency channels in each Smallcell are opened, and wherein, radio-frequency channel is opened and referred to that to open radio frequency link, transmitter and power amplifier in running order etc.
In above-mentioned steps 201, for a Smallcell, local controller is according to the energy saving period in the power save parameters corresponding for described Smallcell of storage, and according to current time, it is judged that whether Smallcell is in described energy saving period. For example, energy saving period corresponding for i-th Smallcell is: 00:00～10:00, if current time is 19:00:05, then may determine that this Smallcell is not at energy saving period, if current time is 09:00:20, then may determine that this Smallcell is in energy saving period.
In above-mentioned steps 202, if Smallcell is in energy saving period, then according to the energy conservation starting thresholding in power save parameters, it is judged that whether Smallcell meets energy saving condition, the Smallcell only meeting energy saving condition just can carry out the closedown of respective radio-frequency passage.
Wherein, it is judged that whether Smallcell meets the mode of energy saving condition is set in advance, in the embodiment of the present invention, alternatively, some or all of according in following manner, it is judged that whether described Smallcell meets energy saving condition, including:
The downlink resource occupancy thresholding that active user's number of described Smallcell is not more than the number of users thresholding in described energy conservation starting thresholding, the current downlink resource occupation amount of described Smallcell is not more than in described energy conservation starting thresholding.
Said method gives the three kinds of modes judging whether Smallcell meets energy saving condition:
Mode one, Smallcell active user's number be not more than the number of users thresholding in energy conservation starting thresholding.
As an example it is assumed that the number of users threshold sets of i-th Smallcell is 3 people, then when active user's number of this Smallcell is less than 3 people, then it is assumed that this Smallcell meets energy saving condition.
Mode two, Smallcell current downlink resource occupation amount be not more than the downlink resource occupancy thresholding in energy conservation starting thresholding.
As an example it is assumed that the downlink resource occupancy threshold sets of jth Smallcell is 5%, then when the current downlink resource occupation amount of this Smallcell is lower than 5%, then it is assumed that this Smallcell meets energy saving condition. Wherein, downlink resource is send the PRB (PhysicalRecourceBlock, Physical Resource Block) that downlink data calls.
Mode three, Smallcell active user's number be not more than the number of users thresholding in energy conservation starting thresholding, and the current downlink resource occupation amount of Smallcell is not more than the downlink resource occupancy thresholding in energy conservation starting thresholding.
Which is when the condition of mode one and mode two meets simultaneously, just thinks that this Smallcell meets energy saving condition.
For example, the number of users threshold sets assuming kth Smallcell is 2 people, and downlink resource occupancy threshold sets is 8%, then when active user's number of this Smallcell is less than 2 people, and when current downlink resource occupation amount is less than 8%, then it is assumed that this Smallcell meets energy saving condition.
Specifically, it is any that one Smallcell uses in above-mentioned three kinds of modes, can according to the feature in this Smallcell region covered, being pre-configured in the energy conservation starting thresholding of this Smallcell correspondence power save parameters, wherein energy conservation starting thresholding comprises number of users thresholding and downlink resource occupancy thresholding respectively.
Certainly, in actual applications, it is also not limited to use above two thresholding to judge whether Smallcell meets energy saving condition. Such as can also using other energy conservation starting thresholding, the peak flow thresholding etc. of such as Smallcell, peak flow thresholding refers to when the peak flow of Smallcell is less than this peak flow thresholding, it is believed that this Smallcell meets energy saving condition.
Additionally, active user's number and the current downlink resource occupation amount of Smallcell can periodically obtain, for example, RRC (the RadioResourceControl of Smallcell, wireless heterogeneous networks) number of users under the current Smallcell of module periodic statistics, and statistical result is reported OAM (OperationAdministrationandMaintenance, the operation management maintainance) module of Smallcell; MAC (MediaAccessControl, media get involved key-course) the module periodic statistics current downlink resource occupation amount of Smallcell, and report the OAM module of Smallcell.
Local controller is periodically to the number of users under the OAM module polls of Smallcell once this Smallcell and downlink resource occupancy.
Wherein, the cycle that local controller obtains active user's number and current downlink resource occupation amount to the OAM module of Smallcell is T1, for instance T1 is 3 seconds, or 5 seconds etc.
The OAM module of Smallcell obtains active user's number to RRC module, and is T2 to the cycle of MAC module acquisition current downlink resource occupation amount, for instance T2 is 4 seconds, 5 seconds etc.
Wherein, cycle T 1 can be identical with T2, it is also possible to differs.
In addition, local controller is periodically to the number of users under the OAM module polls of Smallcell once this Smallcell and downlink resource occupancy, can be before step 201, can also need in step 202. to obtain again when the number of users under use Smallcell and downlink resource occupancy, specifically depending on being actually needed.
In above-mentioned steps 203, if described Smallcell meets energy saving condition, then according to the Energy Saving Strategy in described power save parameters, generate radio-frequency channel shutdown command and be sent to described Smallcell, so that described Smallcell is according to the shutdown command of described radio-frequency channel, close the radio-frequency channel in described Smallcell.
Owing to Smallcell is in energy saving period, and this Smallcell meets energy saving condition, then think that this Smallcell currently need not open all of radio-frequency channel really, therefore can according to the Energy Saving Strategy pre-set, generate radio-frequency channel shutdown command, then radio-frequency channel shutdown command is sent to Smallcell, Smallcell after receiving radio-frequency channel shutdown command, close the portion radio frequency passage in Smallcell
Specifically, close which radio-frequency channel in Smallcell, can be through radio-frequency channel shutdown command and inform which radio-frequency channel Smallcell closes, it is also possible to as long as being that Smallcell receives radio-frequency channel shutdown command, just closing one of them radio-frequency channel in order.
It is described in detail below for the first mode closing radio-frequency channel.
Alternatively, described according to the Energy Saving Strategy in described power save parameters, generate radio-frequency channel shutdown command and be sent to described Smallcell, so that described Smallcell is according to the shutdown command of described radio-frequency channel, close the radio-frequency channel in described Smallcell, including:
According to described Energy Saving Strategy, it is determined that need the radio-frequency channel closed;
According to the radio-frequency channel needing to close determined, generate the shutdown command of described radio-frequency channel;
The shutdown command of described radio-frequency channel is sent to described Smallcell, so that described Smallcell is according to the shutdown command of described radio-frequency channel, closes the radio-frequency channel needing to close described in described Smallcell.
In the method, local controller is according to Energy Saving Strategy, determine the radio-frequency channel needing to close, then according to the radio-frequency channel needing to close determined, generate radio-frequency channel shutdown command, and the shutdown command of described radio-frequency channel is sent to Smallcell, Smallcell after receiving radio-frequency channel shutdown command, therefrom obtain the information of the radio-frequency channel needing closedown, thus closing the radio-frequency channel needing to close. The method, is by needing the radio-frequency channel closed to be carried in the shutdown command of radio-frequency channel by local controller, such that it is able to inform that Smallcell needs to close which radio-frequency channel.
Wherein, according to Energy Saving Strategy, it is determined that need the radio-frequency channel closed, it is possible to be predefined Energy Saving Strategy, such as Smallcell, it is assumed that this Smallcell, by 5 radio-frequency channels, is numbered radio-frequency channel 1, radio-frequency channel 2 respectively, radio-frequency channel 3, radio-frequency channel 4, radio-frequency channel 5.
If Energy Saving Strategy may is that number of users is equal to 1, or downlink resource occupancy is less than 2%, then close wherein three radio-frequency channels (namely retaining two radio-frequency channels to open); If number of users is equal to 2, or downlink resource occupancy is more than 2% and less than 4%, then close two of which radio-frequency channel (namely retaining three radio-frequency channels to open), etc.Specifically Energy Saving Strategy, it is possible to set according to practical situation.
In above-mentioned steps 202, it is judged that whether Smallcell meets energy saving condition, if meeting energy saving condition, then implement according to the mode of step 203. If being unsatisfactory for energy saving condition, can implement as follows.
Alternatively, described judge whether described Smallcell meets energy saving condition after, also include:
If described Smallcell is unsatisfactory for energy saving condition, and the current downlink resource occupation amount of described Smallcell is more than the energy-conservation closedown thresholding in described power save parameters, and described Smallcell has radio-frequency channel to be closed, then generate radio-frequency channel first according to described Energy Saving Strategy open order and be sent to described Smallcell, so that described Smallcell opens order according to described radio-frequency channel first, open the radio-frequency channel in described Smallcell.
In said method, Smallcell is currently at energy saving period, but Smallcell is unsatisfactory for energy saving condition, and the current downlink resource occupation amount of Smallcell is more than the energy-conservation closedown thresholding in power save parameters, and Smallcell has radio-frequency channel be closed, now generate radio-frequency channel first according to Energy Saving Strategy open order and be sent to Smallcell, Smallcell receiving after radio-frequency channel first opens order, open radio-frequency channel therein.
For example, the energy saving period of Smallcell is 08:00～15:00, current time is 14:00:00, the energy saving condition of Smallcell is: downlink resource occupancy threshold sets be 5% and number of users thresholding be 3 people, energy-conservation closedown thresholding is 80%, active user's number is 20 people, and current downlink resource occupation amount thresholding is 90%.
Although now Smallcell is in energy saving period, but (namely current downlink resource occupation amount thresholding is 90% to be unsatisfactory for energy saving condition, be unsatisfactory for energy saving condition: downlink resource occupancy threshold sets be 5% and number of users thresholding be 3 people), and the current downlink resource occupation amount of Smallcell is more than energy-conservation closedown thresholding (the i.e. current downlink resource occupation amount 90% of Smallcell in power save parameters, more than energy-conservation closedown thresholding 80%), it is taken as that although this Smallcell is in energy saving period, but owing to current downlink resources flowing amount is bigger, if therefore currently there being the radio-frequency channel being closed, then need for opening radio-frequency channel.
Which, as the radio-frequency channel opened in being closed, also determine according to Energy Saving Strategy set in advance. Alternatively, described according to described Energy Saving Strategy generate radio-frequency channel first open order and be sent to described Smallcell so that described Smallcell opens order according to described radio-frequency channel first, open the radio-frequency channel in described Smallcell, including:
According to described Energy Saving Strategy, it is determined that need the radio-frequency channel opened;
According to the radio-frequency channel that the needs determined are opened, generate described radio-frequency channel first and open order;
Order is opened in described radio-frequency channel first and is sent to described Smallcell, so that described Smallcell opens order according to described radio-frequency channel first, open the radio-frequency channel needing to open described in described Smallcell.
Set as an example it is assumed that i-th Smallcell has in the Energy Saving Strategy of 10 radio-frequency channels: if current downlink resource occupation amount is more than 85% and less than 90%, it is determined that open 9 radio-frequency channels therein;If current downlink resource occupation amount is more than 90%, it is determined that open all of radio-frequency channel. Certainly how concrete Energy Saving Strategy sets, depending on being actually needed.
It addition, in above-mentioned steps 201, it is judged that whether Smallcell is in energy saving period, if being in energy saving period, then implements according to the method for step 202～step 203, if being not at energy saving period, then can implement as follows.
Alternatively, the energy saving period in the described power save parameters corresponding according to Smallcell, it is judged that described Smallcell also includes after whether being in described energy saving period:
If described Smallcell is not at described energy saving period, and a described Smallcell upper cycle is in described energy saving period, and described Smallcell has radio-frequency channel to be closed, then according to described Energy Saving Strategy, generate radio-frequency channel second open order and be sent to described Smallcell, so that described Smallcell opens order according to described radio-frequency channel second, open the radio-frequency channel in described Smallcell.
In said method, Smallcell is not currently in energy saving period, but a upper cycle is in energy saving period, namely this Smallcell just forwards non-energy saving period to from energy saving period, now, if Smallcell there being radio-frequency channel be closed, then according to Energy Saving Strategy, generate radio-frequency channel second open order and be sent to Smallcell, Smallcell is after receiving radio-frequency channel second and opening order, obtain the radio-frequency channel information opened of wherein needing, then open the some or all of radio-frequency channel of radio-frequency channel in Smallcell.
The method that the embodiment of the present invention provides, local controller is according to the energy saving period in power save parameters corresponding to Microcell, it is judged that whether Microcell is in energy saving period; If being in energy saving period, then according to the energy conservation starting thresholding in power save parameters, it is judged that whether Smallcell meets energy saving condition; If meeting energy saving condition, then according to the Energy Saving Strategy in power save parameters, generating radio-frequency channel shutdown command and being sent to Microcell, so that Microcell is according to radio-frequency channel shutdown command, closing the radio-frequency channel in Microcell. When the method is in energy saving period and meets energy saving condition in Microcell, send radio-frequency channel shutdown command to Microcell so that radio-frequency channel can be closed in Microcell, thus reducing the power consumption of radio frequency unit, and then reduces the total power consumption of base station system.
