Description
Technical field
The present invention relates to access net fields, more particularly to the power-economizing method and device of a kind of Along Railway base station.
Background technique
Now, high-speed railway covers the area of most domestic, and route is all selected in remote suburb, in order to give high-speed rail
On user the better network coverage is provided, each mobile operator has set up corresponding matched wireless base station along the railway and has been used to
Guarantee user experience.The huge challenge that high-speed mobile communications face at present has:
(1) penetration loss is big.The new type train of high-speed railway use totally-enclosed carriage body construction, box body be stainless steel or
The metal materials such as aluminium alloy, glass for vehicle window are thicker glass material, lead outdoor wireless signal and penetrate damage in bullet train
It consumes larger, brings larger difficulty to the intracorporal wireless coverage of vehicle.Different trains due to the difference in material and speed, for
The penetration loss difference of wireless signal is very big.The corresponding penetration loss of different incidence angles is different, when signal vertical incidence
Penetration loss is minimum.When the upright position of base station is closer apart from railway, the incidence angle that footprint edges signal enters compartment is small,
Penetration loss is big.
(2) Doppler shift.Train high-speed motion will cause Doppler shift, and receiving end is caused to receive signal frequency hair
Changing, and the size of frequency variation and speed are related to the speed of train.Big frequency deviation caused by high speed demodulates receiver
Performance boost is a greatly challenge.
(3) switching is frequent.Due to single limited coverage area of standing, train high-speed mobile will pass through multiple small in a short time
The coverage area in area causes frequent handover between cells, and then influences the overall performance of network.
At present along the railway generally using RRU (abbreviation of Radio remote unit, Remote Radio Unit) total cell
Technology is developed based on distribution-type base station architecture, is zoomed out by RRU, and BBU be (Building Base band Unite's
Abbreviation, indoor baseband processing unit) under multiple sub-cells physically adhere to different sites separately, logically belong to the same cell.
After the multiple overlay areas RRU for belonging to same logic district partly overlap a chain of be connected, the height of a strip is constituted
The MPS process scheme of the suitable Along Railway of signal strength is conducive to increase covering signal strength, shown in Fig. 1.Cell is covered altogether
Mobile service under lid, all sub-cells all moment that up direction is total to cell all keep reception state, and down direction is small altogether
All moment broadcast channels in all sub-cells in area keep emission state, other channels only select the optimal sub-cell hair of quality
It penetrates.
More RRU, which are total to cell advantage, to be had: (1) reducing the switching of minizone, improve handover success rate.RRU multi-site is total to cell
The coverage area that technology has greatly widened single cell (covers 500 meters of calculating according to single sub-cell, configures 8 sub-cells, then
Covering can reach nearly 4 kilometers), it no longer needs to switch between the different sub-cells of cell altogether, instead different sons are small
Relay between area.Mobile station only enters cell switching when passing through the overlay area and cell switches out, passes through sub-cell
Between switching realization business continuity.(2) carrier frequency utilization rate is improved.Frequency planning difficulty is reduced, interference is reduced.Along Railway
Telephone traffic distribution has specific characteristics, train standoff distance farther out, for an iron leg route, although there is continuous several cells to cover
Lid, but main telephone traffic often focuses in a cell.RRU multi-site is total to the overlay length that cell has elongated cell, mentions
The high utilization rate of frequency point, while reducing the frequency point interference of neighboring community.
But meanwhile more RRU are total in cell, the base station signal of railway mobile communication network be continue transmitting, whether
Have a train process, base station all can outward radiation signal to guarantee that train passes through when enough signals are provided in time, do not having
When thering is train to pass through, many resource energy are wasted；In addition, signal and the runner public-network portion of railway mobile communication network
The base station of administration has overlapping to cover, and base station uses the long-term mode for increasing transmission power for the use on high-speed rail train along high-speed rail
Family provides good enough service, when no high-speed rail train passes through, since frequency range configures, sometimes can also to high-speed rail along the line near
Public network causes serious interference.
Existing technical solution is generally waken up using the base station based on parameters such as loads, is closed.Be adapted to compensate for cell and
The scene of energy-saving cell layered coverage sends cell wake-up call to energy-saving cell when compensating cell load and being more than given threshold
Instruction, activation energy-saving cell handle user's access request；The latter selectively closes off energy-saving cell when loading decline.This side
Case is directed to the tidal effect of user in the cellular network of city and proposes, when daytime, load was higher than certain threshold value, starting energy-saving is small
Area achievees the purpose that power saving with energy-saving cell is turned off when certain threshold value and improves system energy efficiency when loading low at night.
But the above-mentioned base station based on parameters such as loads wakes up, the technical solution of closing needs a door when judgement
Limit value, along the railway in this train under the unfixed scene of number of users, the threshold value of the parameters such as load is difficult to arrange, if setting

Person has compensation base station to cover, and when integral load is lower, compensation base station can also carry a part of load, and load judgement is not required to
It is especially accurate, but the base station that Along Railway is in low-power consumption mode is exclusively used in train user, other typically no bases
It stands covering, when there is any train user arrival, even if Along Railway base station also all must in the case where train user is considerably less
