Description
Technical field
The present invention relates to wireless communication network base station, particularly the power-saving technology of wireless communications network base station.
Background technology
Nineteen sixties, units such as U.S.'s Bell Laboratory have proposed the notion of cellular mobile communication.But the control system that it is complicated, especially the control that realizes travelling carriage is up to the seventies, along with the development of maturation, large scale integrated circuit device and the microprocessor technology of semiconductor technology and the extensive use of surface mount process, just the realization for cellular mobile communication provides technical foundation.Even to this day, cellular mobile communication is from global system for mobile communications (the Global System for mobileCommunication of the second generation, be called for short " GSM ") develop into Wideband Code Division Multiple Access (WCDMA) (Wideband CodeDivision Multiple Access is called for short " WCDMA ") and be the 3-G (Generation Three mobile communication system) of representative.
In wireless communication system,, generally adopt different carrier frequencies it to be cut apart each other with different zones in order to reduce phase mutual interference between contiguous each area communication user.Being about to the scope division that system covered is a plurality of different zones, and different carrier frequencies is adopted in each different zone, that is to say, the frequency of the signal of each regional input and output is fixing and unique.
Along with the development of radio communication, the number of users in the system is more and more, and in order to increase power system capacity, increasing sector number and increasing carrier frequency quantity is two kinds of methods relatively more commonly used.So-called sector is meant and utilizes oriented antenna that the zone of a border circular areas or other shapes is divided into a plurality of sector regions.In mobile communication system, typical sector point-score has three kinds, is respectively omnidirectional sector, three sectors and six sectors.What deserves to be explained is that in real application systems, the zone that utilizes oriented antenna to divide might not be fan-shaped on the geometric meaning, still can be called as the sector but those of ordinary skill in the art are appreciated that these zones.According to the planning and designing method of network system, generally certain geographic areas can be become the network system of m * n sub-district.Wherein, m represents number of sectors, and n represents the carrier number of each sector.Such as, when the WCDMA system network planning designs, according to demand, the somewhere is formulated for 3 * 4 system, then to represent the base station, this area all is configured to 3 sectors, there are 4 carrier waves each sector, totally 3 * 4=12 sub-district; If be formulated for 6 * 2 system, represent that then with this area's base station configuration be 6 sectors, there are 2 carrier waves each sector, totally 6 * 2=12 sub-district.
In wireless communication system, all there is different separately frequencies above-mentioned each sub-district, all needs a cover transceiver.General transceiver all comprises a cover baseband and a radio frequency processing subsystem, and wherein Radio Frequency Subsystem is finished the radiofrequency signal processing.Radio frequency is a radio-frequency current, be that a kind of high-frequency ac changes electromagnetic abbreviation, the alternating current that per second changes less than 1000 times is called low-frequency current, the high-frequency current that is called greater than 10000 times, a kind of high-frequency current and radio frequency comes to this, radio-frequency technique has widely at wireless communication field, irreplaceable effect.Radio Frequency Subsystem will carry out complicated processing such as dual frequency conversion, amplification and frequency discrimination to signal.
The wireless communication system operation principle is roughly as follows:
The existing wireless communications system comprises one or several RNS (Radio NetworkSubsystem, be called for short " RNS "), each RNS is by cell base station node (Node Base Station, abbreviation " NodeB "), radio network controller (Radio Network Controller, abbreviation " RNC "), travelling carriage compositions such as (Mobile Station are called for short " MS ").The base station multi-sector base stations of signal in control, a plurality of sectors of management is arranged and only be responsible for a sector in addition sector in the base station of sub-district of a certain carrier wave of use.
Communicate by wireless air interface Un between each base station and each travelling carriage, radio network controller is communicated by letter by Iub interface with the base station.Main now wireless communication system such as Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access is called for short " WCDMA ") adopt the asymmetric processing of base station up-downgoing.At first carrying out the base station down channel data handles.Promptly give the base station by Iub interface transmit frame agreement (Frame Protoeol is called for short " FP ") packet from radio network controller; Carry out chnnel coding in the base station, promptly carry out coded combination transmission channel (Coded Composite TransportChannel, abbreviation " CCTrCH ") code multiplexing, then carry out baseband modulation, obtain base band data, carry out digital intermediate frequency then, send on the interface Uu between radio network controller and the subscriber equipment by radio frequency processing at last.Radiofrequency signal will be launched at wireless air interface Un interface after the base station down channel data is handled.
In the wireless communication system course of work, radio frequency part is the highest part of base station power consumption, and the power consumption of base station and the heap(ed) capacity of base station, maximum transmission power are relevant.The heap(ed) capacity of base station is relevant with bandwidth, and needed transmitting power size also is different under the different bandwidth rates conditions, and the big more needed transmitting power of bandwidth is just big more.If the operating power of base station does not reach desired power after the bandwidth adjustment, then can emergent power limited and can't meet the requirements of situation, have a strong impact on the channel communication quality, even cause the consequence of link down, conversation loss.Therefore, though not all moment customer volume is all near power system capacity when actual motion in the base station, the base station still will be according to maximum transmission power work to guarantee user's access.
In actual applications, there is following problem in such scheme: power consumption and actual user's magnitude relation are little generally speaking, and in few period of customer volume, the power consumption of base station is wasted in a large number.
Cause the main cause of this situation to be, in order to guarantee that the user can both insert smoothly, the base station when actual motion no matter the active user of its each each carrier wave of sector of being responsible for amount what are, comprise that the active user measures few even when being zero, still will be according to maximum transmission power work.Cause the power consumption of base station to waste in a large number.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, the active user of each carrier wave amount in each sector of accounting base-station is according to the customer volume summation in each sector and preset strategy and determine the needed power amplifier number in this sector.Whether judge the needed power amplifier number in this sector less than the current power amplifier number that is in opening in this sector, if less than the user in the unnecessary power amplifier would be transferred in the power amplifier that still is in opening in this sector, close unnecessary power amplifier again; Otherwise, be in the power amplifier of closed condition to make up the gap if the needed power amplifier number in this sector greater than the current power amplifier number that is in opening in this sector, is then opened.When the current needed power amplifier of decision is counted, leave certain surplus, in order to avoid power amplifier occurs by the situation of frequent opening and closing.
As shown in Figure 1, save the system of base station power consumption in the cordless communication network of the present invention, comprise user's statistic unit of active user's amount of each carrier wave in each sector that is used for accounting base-station; Be used for measuring the customer volume summation of calculating in each sector according to the active user that counts, and in conjunction with presetting the control unit that strategy is determined unlatching behind the needed power amplifier number in this sector or closed power amplifier; And at least one or a plurality of sector and prerequisite mains switch interface of each power amplifier unit that is used to carry the power amplifier unit of at least one carrier wave.
The base station is when actual motion, at first the active user by the carrier wave that each power amplifier unit carried in each sector of user's statistic unit accounting base-station measures, then control unit is measured the customer volume summation of calculating in each sector according to the active user from user's statistic unit, and in conjunction with presetting the needed power amplifier number in definite this sector of strategy, if the needed power amplifier number in this sector is less than the current power amplifier number that is in opening in this sector, then close unnecessary power amplifier by the mains switch interface in the power amplifier unit, if greater than the current power amplifier number that is in opening in this sector, then opening by the mains switch interface in the power amplifier unit, the needed power amplifier number in this sector is in the power amplifier of closed condition to make up the gap.
More than system of the present invention is illustrated, below principle of the present invention is described in detail, concrete principle as shown in Figure 2.
In step 210, active user's amount of the carrier wave that each power amplifier unit carried in each sector is at first added up in the base station.Specifically, user's statistic unit is at first opened in when operation in the base station, and user's statistic unit is added up one by one to each active user's amount that is in the carrier wave that power amplifier unit carried of opening in each sector, afterwards, enters step 220.
In step 220, control unit is measured the customer volume summation of calculating in each sector according to the active user from user's statistic unit, and determines the needed power amplifier number in this sector in conjunction with presetting strategy.Specifically, the active user that control unit calculates the carrier wave that each power amplifier unit carried in each sector measures sum, obtains the customer volume summation in each sector.Judge the needed power amplifier number in this sector according to presetting strategy afterwards, preset in the strategy and to judge that the condition that unnecessary power amplifier is arranged can be that the customer volume summation of sector is lower than first thresholding that presets or the customer volume summation of sector is lower than first thresholding that presets, and to have the customer volume summation that inserts be zero power amplifier; Judge that the not enough condition of power amplifier in the sector can be that customer volume summation in the sector is above second thresholding that presets, and there is the power amplifier that is in closed condition in this sector, according to unnecessary power amplifier or power amplifier deficiency are arranged in this sector of above-mentioned condition judgment, thereby determine the needed power amplifier number in this sector.
Then enter in step 230, judge whether the current power amplifier number that is in opening in the needed power amplifier number in this sector and this sector coincide.Specifically, the needed power amplifier number in this sector that control unit will be determined is before compared with the current power amplifier number that is in opening in this sector, if the needed power amplifier number in this sector then enters step 240 less than the current power amplifier number that is in opening in this sector; Otherwise, then enter step 250.
In step 240, control unit will be closed unnecessary power amplifier.Because the needed power amplifier number in sector is less than the current power amplifier number that is in opening in this sector, therefore, control unit is measured power amplifier less or that no user inserts with the active user and is considered as unnecessary power amplifier, if still there is small number of users to insert in this unnecessary power amplifier, then the user in the carrier wave of its carrying is switched to other are in the power amplifier of opening in the sector, close the unnecessary power amplifier that does not have the user to insert by the mains switch interface then by control unit; If no user inserts in this unnecessary power amplifier, then directly it is closed by the mains switch interface.
In step 250, because the needed power amplifier number in sector is greater than the current power amplifier number that is in opening in this sector, therefore, control unit is open at the power amplifier that is in closed condition in the sector to remedy the deficiency of power amplifier by the mains switch interface, avoid normally to insert, when saving power consumption, also do not influence the base station work quality because of underpower causes the user.
According to principle of the present invention, first execution mode of the present invention is described below.First execution mode of the present invention is only to carry under the situation of a carrier wave at power amplifier in the sector, saves the method for base station power consumption in the cordless communication network.Cordless communication network described in the present embodiment can be global system for mobile communications network, code division multiple access (Code Division Multiple Access, abbreviation " CDMA ") network, CDMA 2000 (Code Division Multiple Access 2000, abbreviation " CDMA2000 ") network, WCDMA network or TD SDMA (Time Division SynchronousCode Division Multiple Access is called for short " TD-SCDMA ") network.There are a plurality of power amplifiers and a plurality of carrier wave in each sector in this cordless communication network, and power amplifier can be that the single carrier power amplifier also can be a multi-carrier power amplifier, but a carrier wave can only be by a power amplifier carrying.
In the present embodiment, two single carrier power amplifiers are arranged in the same sector, be respectively power amplifier 1 and power amplifier 2, each single carrier power amplifier is carrier wave of carrying at most, power amplifier 1 bearing carrier wave 1, power amplifier 2 bearing carrier waves 2.User's statistic unit is at first opened in the base station when operation, user's statistic unit is realized by the radio network controller of base station in the present embodiment.User's statistic unit is added up one by one to active user's amount of the carrier wave that each power amplifier unit carried that is in opening in the sector, and promptly adds up active user's amount of the carrier wave 2 that carrier wave 1 that power amplifier 1 carried and power amplifier 2 carried respectively.
Then, control unit calculates active user's amount of the carrier wave 1 that power amplifier 1 is carried in the sector and the active user of the carrier wave 2 that power amplifier 2 is carried measures sum, obtains the customer volume summation in the current time sector.Again the customer volume summation is compared with first thresholding of setting, if the customer volume summation is lower than first thresholding, active user's amount of the carrier wave 2 that carried of the carrier wave 1 that carried of power amplifier 1 and power amplifier 2 relatively then, the power amplifier that customer volume is less is considered as unnecessary power amplifier.Suppose that power amplifier 2 customer volumes are less, be unnecessary power amplifier, control unit carries out alien frequencies by radio network controller and switches, user in the carrier wave 2 of power amplifier 2 carrying switched in the carrier wave 1 with power amplifier 1 carrying of sector go, close the power amplifier 2 that does not have the user by the mains switch interface of power amplifier 2 again, thereby the power consumption of power amplifier is reduced to original 50 percent, saves this time period system power dissipation greatly.
Otherwise, after any time, if the customer volume summation surpasses second thresholding preset, then open with the power amplifier 2 that is in closed condition in the sector by the mains switch interface, to remedy the deficiency of power amplifier, avoid reducing the quality that the user inserts.Because the characteristic of human lives's habit and location, base station, cause the most of the time of most of base station all to be in lower user's access amount state, by closing a power amplifier, fundamentally saved system power dissipation in the less time period of user's access amount (for example shopping centre at night).
According to principle of the present invention, second execution mode of the present invention is described below.Second execution mode of the present invention is to be multi-carrier power amplifier at power amplifier in the sector, and each power amplifier can carry under the situation of one or more carrier waves, saves the method for base station power consumption in the cordless communication network.
In the present embodiment, same sector comprises two power amplifiers that can carry two carrier waves.Power amplifier 1 is in bearing carrier wave 1 or the carrier wave 2 separately, also bearing carrier wave 1 and carrier wave 2 simultaneously.Power amplifier 2 is in bearing carrier wave 3 or the carrier wave 4 separately, also bearing carrier wave 3 and carrier wave 4 simultaneously.
At a time, two power amplifiers have been opened in the base station, power amplifier 1 bearing carrier wave 1,2; Power amplifier 2 bearing carrier waves 3,4.User's statistic unit is at first opened in the base station, and user's statistic unit is realized by the baseband portion of base station in the present embodiment.User's statistic unit is added up one by one to active user's amount of the carrier wave that each power amplifier unit carried that is in opening in the sector, and promptly adds up active user's amount of the carrier wave 3,4 that carrier wave 1,2 that power amplifier 1 carried and power amplifier 2 carried respectively.
Then, control unit calculates active user's amount of the carrier wave 1,2 that power amplifier 1 is carried in the sector and the active user of the carrier wave 3,4 that power amplifier 2 is carried measures sum, obtains the customer volume summation in the current time sector.The customer volume summation is compared with first thresholding of setting again, if the customer volume summation is lower than first thresholding, then compare active user's amount that power amplifier 1 and power amplifier 2 are carried, the power amplifier that customer volume is less is considered as unnecessary power amplifier.Suppose that power amplifier 2 customer volumes are less, be unnecessary power amplifier, then the data of the carrier wave 3,4 of carrying on the power amplifier 2 are issued the power amplifier 1 at carrier wave 1,2 places.
Close the no longer power amplifier 2 of bearing carrier wave by control unit by the mains switch interface then, to save power consumption.
Afterwards, insert the change of number along with the user, at a time, if the customer volume summation surpasses second thresholding that presets, then open with the power amplifier 2 that is in closed condition in the sector by the mains switch interface, can open a carrier wave ratio such as carrier wave 3 this moment earlier, opens another carrier wave ratio such as carrier wave 4 again if the customer volume summation further increases and surpassed another thresholding, thereby improved power system capacity.
According to principle of the present invention, the 3rd execution mode of the present invention is described below.The 3rd execution mode of the present invention is to be under the situation of zero power amplifier at the customer volume summation that exist to insert in the sector, the method for saving base station power consumption in the cordless communication network.
The sector comprises a plurality of power amplifiers and a plurality of carrier wave in the present embodiment, and power amplifier can be that the single carrier power amplifier also can be a multi-carrier power amplifier, and each power amplifier can carry a power amplifier also can carry a plurality of power amplifiers.Base station baseband is partly added up active user's amount of each each carrier wave of power amplifier, calculate the customer volume summation in the current time sector, if the customer volume summation is lower than the first default thresholding, and there is certain power amplifier, its all carrier waves all do not have the user to insert, then close the power amplifier that does not have the carrier wave that the user inserts, thereby save system power dissipation; If the customer volume summation is higher than preset second threshold, then open with carrier wave that is in closed condition in the sector and corresponding power amplifier thereof.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
