Embodiment
Base station apparatus of the present invention is based on the big base station of traditional 1C7T, and the big base station of tradition comprises following a few part: network interface and baseband processing unit; Modem module is divided into principal and subordinate's two parts, carries out the modulation and the diversity reception of 4 road signals respectively; 8 road radio-frequency front-ends comprise radio-frequency (RF) transceiver and power amplification/low noise amplification module respectively; 8 road air feedback units.Wherein network interface and baseband processing unit are responsible for and the interface of network side and the processing of baseband signal, and the main interface between it and the modem module is the transmission data and the tranmitting data register of serial, and serial received data and receive clock.Because modem module is divided into two stations of principal and subordinate, like this between network interface and baseband processing unit and the modem module just by two groups independently the serial receiving and transmitting signal carry out interface.Transmission intermediate frequency signal between modem module and the radio frequency, descending aspect modem module will carry out up-conversion and power amplification to radio frequency through the intermediate-freuqncy signal of ovennodulation, and up aspect radio frequency will be separated the mediation diversity to modem module through the intermediate-freuqncy signal of LNA and down-conversion and merge.By N Connector, transmit the radiofrequency signal of 1.9GHz between radio frequency and the air feedback unit.
The present invention need increase a control unit in network interface and baseband processing unit, be used to control the binding mode of base station.This control unit can be a processing module that increases in the FPGA (Field Programmable Gate Array) of network interface and baseband processing unit, between it and the upper layer software (applications) interface is arranged, software tells by this interface which kind of binding mode is FPGA (Field Programmable Gate Array) adopt, thereby FPGA (Field Programmable Gate Array) is carried out process described below and bundled operation accordingly.When telephone traffic than higher the time, take normal 1C7T binding mode to increase the number of Traffic Channel, we can be referred to as " time slot binding ".And when telephone traffic was lower, the mode of taking another to be referred to as " antenna binding " became a 1C3T with the base station binding of two 1C3T.This mode doubles transmitting power and receiving sensitivity on the basis of having sacrificed half Traffic Channel.
Be different from " the time slot binding " of front, under " antenna binding " mode, two groups of serial base band receiving and transmitting signals between network interface and baseband processing unit and the modem module are reduced to one group, and what carry out modulation and demodulation by principal and subordinate's modem module is same group of base band data.These changes all can by foregoing interface, be finished corresponding conversion by programmable logic cells by software control in inside.Same group of downstream signal will be by 8 modulation channels modulation when posting a letter like this, and 8 antennas send.And original principal and subordinate's modem module has only 4 modulation channels respectively, 4 antennas, and the power of so just will posting a letter has increased by one times.And upward signal will have been become 8 antennas by 4 original antenna diversities and carry out diversity reception when collecting mail, and corresponding receiving gain also can increase.When increasing, transmitting power satisfies the requirement of up-downgoing receiving-transmitting balance.
In the following description, under time slot binding mode situation, we close with antenna binding sign and represent, and bundle under the mode situation at antenna, open with antenna binding mode and represent.
Fig. 1 is the situation that antenna binding Warning Mark is closed in network interface and baseband processing unit.The base station of this moment is exactly the logical big base station of 1C7T of a Daepori.1.1 is network interface and Base-Band Processing part among the figure, the 1.2nd, and modem section, 1.3 is radio frequency part, and 1.4 is power supply and other aid in treatment part, and these have formed a complete base station.The interface of base station comprises network side interface and air interface.1.1.1 be initiate control unit among the present invention, represent antenna binding Warning Mark with switch form among the figure, switch disconnects represents that the time slot of taking to give tacit consent to bundlees mode.Wherein modem module is divided into two parts of principal and subordinate, and two-part structure is just the same.Comprise that respectively " modulating unit+D/A switch " circuit of a four-way is modulated to base band data the diversity reception unit of a suitable intermediate frequency and a four-way, the upward signal that No. four antennas are received is demodulated into base band data, also will recover data clock simultaneously and pass to network interface and Base-Band Processing part.
Under this working method, the up-downgoing baseband signal between network interface and Base-Band Processing and the modem section has two groups respectively, is independently handled respectively by principal and subordinate's modulator-demodulator.
Fig. 2 is antenna binding Warning Mark when opening, and works according to the signal connected mode among the figure in the base station.Be equivalent to the big base station of a 1C3T this moment, but power and receiving sensitivity will double in theory.Different with Fig. 1 is that antenna binding indication 1.1.1 is closed this moment, and the base station takes the mode of antenna binding to increase power.
Under this working method, the up-downgoing baseband signal between network interface and Base-Band Processing part and the modem module has only one group.Quite with two independently four-way receive synthetic one 8 modem module of receiving 8 of modem module that four-way is sent out.Do not need to do change for radio-frequency front-end, but corresponding radio-frequency (RF) control signal may need to change according to the data of actual transceiver.Concrete, under the mode of time slot binding, if a certain time slot of homophony system demodulating unit need be sent out data, the radio-frequency (RF) switch signal that need open this time slot correspondence so gets final product, and does not need to open from the radio-frequency (RF) switch signal of modem module correspondence.And under the antenna binding mode, what principal and subordinate's modem module sent is identical information, if therefore a certain time slot need send data, then the radio-frequency (RF) switch signal of principal and subordinate's modem module correspondence just need be opened simultaneously at this moment.
The front has been described the base station among the present invention, and except the network and the baseband processing unit of normal base station, modem module beyond radio-frequency front-end and the air feedback unit, has also comprised the unit of a control binding mode.Network and Base-Band Processing part also will be done certain processing to the base band downstream signal except increasing control unit, specifically, when receiving antenna binding indication, just can not be again as sending the two-way data of posting a letter at the beginning.Because the base band serial data of this moment has only one group, and the modem module needs is two groups of data of posting a letter.At this time network and Base-Band Processing part need be issued the data of posting a letter two input ports of posting a letter of modem module simultaneously.Just two groups of original data of posting a letter are linked together at network and Base-Band Processing partial interior.Changing more in addition is that the radio-frequency (RF) switch signal is also partly given radio frequency part by network and Base-Band Processing usually, and the radio-frequency (RF) switch signal also will be made variation as mentioned before synchronously like this.
In order to allow modem module also obtain the information of antenna binding indication, to increase an interface between network and Base-Band Processing part and the modem module and be used for the marker antenna Binding information.Concrete mode can adopt modem module internal register etc.In case receive antenna binding Warning Mark, what modem module need change mainly is the upstream data aspect.Because two up four-way diversity receptions of this moment need be merged into one eight passage diversity reception.The diversity demodulating algorithm need be made certain change like this.And when switching, and the data-interface between network and the Base-Band Processing part also changes, and two groups of original base band datas become one group, and wherein no one group of FPDP is then forbidden dateout.
Fig. 3 adopts manually operated method to change the binding mode of base station, adopts this mode can change the bundle status of base station by the background net management manmachine command at any time.Owing to be the binding that changes according to TCH (Traffic Channel), and can not have influence on the state of CCH (control channel), therefore can at any time the base station be changed the binding mode, and not need to restart the base station or withdraw from operation state, this has further increased the flexibility of this scheme.
As shown in Figure 3, after the base station powers on,, enter operation state after the initialization synchronously at first according to normal startup flow process.At this time can change the binding mode (antenna binding or time slot binding) of base station at any time according to the needs input manmachine command of coverage.The base station default conditions are common time slot binding mode, 1C7T base station just, when needs increase coverage, when just needing to increase power, just open antenna binding indication, the relevant connection mode and the flow process of network and Base-Band Processing part and modem module adjusted in the base station at once according to the description of top hardware components, the base station becomes 1C3T, the base station that power and receiving sensitivity double.Coverage also increases accordingly simultaneously.
Fig. 4 adopts the binding mode of controlling the base station according to telephone traffic automatically, and on manually operated basis shown in Figure 3, software section increases the module and the interface of a traffic statistic.Set the telephone traffic thresholding of a period of time, i.e. unit interval telephone traffic thresholding.It is similar to start flow process and above-mentioned Artificial Control, at first enters normal operation state, and statistical unit time telephone traffic after after a while is higher when the unit interval telephone traffic, when surpassing the threshold value of setting, does not change bundle status.When being lower than thresholding, open antenna binding sign switch automatically, the base station becomes high-power 1C3T base station.And the base station can be at any time changes the binding modes automatically according to what of unit interval telephone traffic.
It should be noted that in this way the frequency of adjusting can not be too high.Because telephone traffic is random fluctuation, the unit interval can be established to such an extent that grow a bit.
In addition, utilize telephone traffic time dependent characteristics in a day, also can change the binding mode of base station according to the different time periods, the time period less in telephone traffic enlarges covering, and increases the number of Traffic Channel in the higher period of telephone traffic.
