Description
Technical field
The present invention relates to Long Term Evolution (LTE) mobile communication technology, espespecially a kind of method and system of selecting energy-saving cell.
Background technology
Existing energy-saving scheme is the target that realizes reducing energy consumption by closing energy-saving cell mostly.Its basic procedure roughly comprises:
The closing flow path of energy-saving cell: energy-saving cell is according to information on load, and autonomous decision enters power save mode; Closing the decision that energy-saving cell makes it to enter power save mode also can be sent by oam (OAM, Oprate and Management); Prepare to close when entering power save mode when energy-saving cell, it can switch to neighbor cell with the subscriber equipment in the coverage (UE, User equipment), and shows that switch reasons is because power-save operation; This shutoff operation of energy-saving cell notice neighbor cell.
When the load rise of the residential quarter that basic covering is provided (namely controlling the jurisdiction district, base station), can wake energy-saving cell up by residential quarter activation (Cell Activation Procedure), make it to enter operating state.The unlatching flow process of energy-saving cell comprises: the decision that wakes energy-saving cell up can be sent by OAM; Energy-saving cell responds wake operation usually, enters operating state; It has withdrawed from energy-saving cell notice neighbor cell power save mode and has entered operating state.
When the load rise of control jurisdiction district, base station, should select suitable energy-saving cell to wake up.Suitable energy-saving cell refers to, after energy-saving cell was waken up, it can bear suitable load for control jurisdiction district, base station.Also pointed out to come by following approach the selection of Optimization of Energy Saving residential quarter in the existing energy-saving scheme: do not carry out any optimization, OAM sets in advance strategy, and interference power and thermal noise power ratio (IoT, Interference over Thermal) are measured, UE measures, positional information.
Wherein, do not carrying out in the method for any optimization, one or more activation are chosen only according to the information on load of this locality in control jurisdiction district, base station from alternative energy-saving cell.This algorithm expense is low, but energy-saving efficiency may be not high; In the OAM strategy, system log (SYSLOG) the periodic law of low load, then preseted open and close time of energy-saving cell by OAM.The method complexity is low, when system load varies compares rule, and good energy-conserving effect.But the method is for dynamic changeable complex situations, and low precision is difficult to play good energy-saving effect;
In the IoT method of measurement, when control jurisdiction district, base station load rises, can open the monitor function of energy-saving cell and measure IoT, thereby need judge whether the starting energy-saving residential quarter.The method precision is high, good energy-conserving effect, but owing to wanting the monitor function of starting energy-saving residential quarter, overhead is large, and also can expend certain energy consumption;
In the UE method of measurement, energy-saving cell can be opened a period of time with pilot signal, and the signal strength signal intensity of the UE energy-saving cell that just can measure according to oneself judges whether to be positioned at the coverage of energy-saving cell like this.The method also is that precision is high, but needs the partial function of starting energy-saving residential quarter, and overhead is large;
In the method that adopts positional information, positional information and the covering radius of energy-saving cell are known in advance.It is by the positional information of positioning UE, then compares to judge load in the energy-saving cell coverage with the positional information of energy-saving cell.The method precision is higher, also need not to open energy-saving cell, but it need to know the positional information of energy-saving cell, therefore and be not suitable for laying flexibly, the uncertain energy-saving cell scene of positional information.
