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.
Referring to Fig. 3, the present invention is a kind of mobile communications device of realizing that channel is shared fully, the band signal processor of the base station that this device connects to form for the Channel Processing plate CHU, the radio frequency interface unit R IU that are arranged to parallel mode work by four and six Transmit Receive Unit TRX, each CHU goes up to join end to end by two and forms daisy chain, and shares the Channel Processing special chip CSM (referring to Fig. 6) of one group of front and back to transmit port, and a plurality of channel banks that are used for finishing the modulation and demodulation of CDMA Channel digital baseband signal are arranged in each CSM chip; 6 groups of forward direction/backs that each CHU is defeated by 6 sector datas are all converged to (output/input) port and are connected to RIU, wherein 6 groups of forward direction ports data of exporting to RIU are distributed them to arrive the accumulator of different sectors respectively by the data routing module among the RIU, and each sector accumulator all has the uplink port from different CHU.This accumulator is finished adding up of different CHU input signals, finishes time domain interpolation, signal shaping filtering and sequential adjustment respectively by the logic of back again, delivers to TRX at last and does further processing.The reverse data of each sector of being sent here by TRX also duplicates in RIU and delivers to all simultaneously and have with it among the CHU that forward data is connected.One of innovation key of the present invention is to be provided with two field programmable gate array chips (FPGA) in RIU, be respectively applied for and make up support above-mentioned forward direction circuit that 2 years 3 fan channels are shared fully and back to circuit, make each the Channel Processing special chip on each channel board have at least a port to connect the radio-frequency (RF) transmit-receive circuit of different carrier frequency, different sectors respectively, realize the transmission of front and back to data.
Here need to be illustrated as the direct addition of data that what handles special chip from different channels and can not cause obscuring this and determining of information by CDMA signal own characteristic.As everyone knows, CDMA is a self-interference system, and the signal of different channels is exactly noise each other, must extract the information of respective channel by specific orthogonal code.Therefore, as long as different channels handles that special chip produces a plurality of add with signal in do not have signal by a plurality of channels of same orthogonal code modulation, add in theory and after signal and the multichannel composite signal that produces by a Channel Processing special chip without any difference! The theoretical foundation that the present invention that Here it is can realize; Simultaneously, therefrom also can learn: user's (channel) number that " channel is shared fully " device can be supported in certain sector, can not be above the number of orthogonal code that band spectrum modulation adopts in the cdma system.
Referring to Fig. 4, specifically introduce the forward direction circuit of the 2 years 3 complete common share communication devices of fan channel among the Fig. 3 of configuration in the frame of broken lines wherein:
Four resource pool pool0-3 that insert logic as the data of the first order respectively with the corresponding connection of four Channel Processing plates of CHU0～CHU3,6 data interfaces of each channel board are respectively among 6 TRX each by resource pool and forward data processing logic one tunnel output are provided, the forward direction of the Channel Processing special chip on each Channel Processing plate output can be connected to any sector of carrier frequency f1 and f2 like this, by the CHU drive software can with for the output signal of the channel bank of different sectors service from its corresponding sector output port output.
Whether the port controlling switch that is controlled by system controlling software imports resource pool to the port data of each CHU is controlled respectively, when certain CHU breaks down or groove position vacancy, can turn-off the first order data corresponding by master control borad and insert the invalid port of Pool i in the logic, avoid introducing interference signal back level signal processing is produced interference from these invalid mouthful with this fault or vacant locations.
Follow-up forward direction logical circuit is divided into multistage: be linked in sequence separately 2 years 3 fans totally six groups of forward direction baseband signal numeric fields add and, to add and after signal do time domain interpolation, base band shaping filtering etc. and finish the treatment circuit that speed and bandwidth are adjusted, and carry out and go here and there the circuit that conversion and sequential adjust, distinguish dateout to six a Transmit Receive Unit TRX at last.The six knob forward signal treatment circuits of comprise just that the forward direction baseband signal that different CHU are delivered to same sector sums up respectively, interpolation, filtering and sequential being adjusted.In fact, this part forward direction circuit is the core that the present invention realizes " channel is shared fully " technology, each sector all comprise adding of I, Q two paths of signals and, function such as interpolation, base band shaping filtering.
Because each sector of each carrier frequency all can have I, Q two paths of signals to need to handle, therefore the base station transceiver part of 2 years 3 fans just has 12 road I, Q signal needs to handle.In order to improve integrated level, in monolithic FPGA, realize whole circuit logics, the present invention adopts some special technologies to reduce the shared resource of interlock circuit: for example add with circuit and adopt the serial addition circuit, filter circuit is the finite impulse response filter circuit that distributed algorithm, its filter factor can be revised.
Referring to Fig. 5, specifically introduce among the Fig. 3 of configuration in the frame of broken lines wherein the back to circuit of 2 years 3 complete sharing means of fan channel: 6 inputs of each CHU connect 6 different TRX of 2 years 3 fans respectively, the reverse data that 6 road TRX receive is given the particular port of 6 CHU respectively according to the corresponding relation of itself and forward direction circuit.The CHU drive software is according to system configuration and operating state, determines which is effective in 6 ports of this plate, and the Channel Processing special chip that is provided with again in this CHU is handled the input data of these ports.So just the reverse data of each sector all can be duplicated and deliver to all Channel Processing special chips.
Referring to Fig. 6, two CSM serially concatenateds of each CHU inside of the present invention are formed daisy chain, shared one group of input/output port.Be the situation that is used for compatibility " not exclusively Channel Sharing " wherein from the input of prime Channel Processing plate with to subordinate's processing channel plate output.Always have four dispensing units among this figure: configuration 1-configuration receives input port, configuration 2-configuration cascade input port, the transmission output port of first CSM in the configuration 3-configuration plate, the transmission output port of second CSM in the configuration 4--configuration plate; These configurations be used to realize the daisy chain in the Channel Processing plate CHU connects and fault after reconstruct.This 4 configurations of applying in a flexible way can realize the redundancy scheme of CSM baseband signal input port, output port and tandem inbound port.Belong to the state of the art because the technology of different configurations is set according to various situations, just give unnecessary details no longer in detail here.
Support 6 groups of input/output ports at most owing to use the CSM of Qualcomm's modulation widely chip at present, therefore, when the set of sectors number in the whole base station system (carrier frequency number * sector number) greater than 6 the time, when for example fan disposed in 3 years 3, just can not allow the special-purpose CSM chip of a slice Channel Processing directly support the communication of all set of sectors.According to analysis, only when the configuration (when being 4 Channel Processing plates of foregoing employing CHU) of 2 years 3 fans still often can not be satisfied user's needs the sub-district in, just need be configured to fan or more multiprocessing ability in 3 years 3 to reality operation situation.For this reason, the present invention also provides the communicator that the channel of " 4+2 " is as shown in Figure 7 shared fully.
Referring to Fig. 7-9, introduce the another kind of mobile communications device of realizing that channel is shared fully, it is the band signal processor of the base station that connected to form by six Channel Processing plates, radio frequency interface unit and nine Transmit Receive Unit, on each Channel Processing plate also be have two connect into daisy chain, and share one group before and after to the Channel Processing special chip of transmit port, a plurality of channel banks that are used for finishing the modulation and demodulation of CDMA Channel digital baseband signal are arranged in each Channel Processing special chip; Be characterized in: six Channel Processing plates of parallel mode work are divided into two groups: first group has four, second group to have two; 6 input/output end ports of each Channel Processing plate and each sector Data transmission all converge and are connected to the radio frequency interface unit, in the radio frequency interface unit, be provided with two field programmable gate array chips (FPGA), be respectively applied for and make up support forward direction circuit that 3 years 3 fan channels are shared fully and back to circuit, make that respectively organize each Channel Processing special chip on the channel board has a port connect this group respectively different carrier frequency that belonged to, the radio-frequency (RF) transmit-receive circuit of different sectors at least, realizes the transmission of front and back to data.
Wherein first group of CHU0, the CHU1 of the forward direction circuit among Fig. 8, four Channel Processing plates of CHU2, CHU3 constitute the 2 years 3 complete share technique schemes of fan channel, from these four CHU0-3 any one can be exported the base band data of 6 sectors, receives 6 TRX:TR0, TR1, TR3, TR4, TR6, TR7 respectively; Be that each CHU has to the path of any one TRX wherein, thereby realize that channel is shared fully.Two Channel Processing plates of second group of CHU4, CHU5 also are to export 6 sector datas respectively, but are divided into 3 groups and receive 3 TRX:TR2, TR5, TR8 respectively, realize that the channel of fanning in single year 3 is shared fully.Although in this device, 6 CHU are actual to be divided into 2 groups, and first group is 4 Channel Processing plates, and second group of 2 Channel Processing plate realizes that respectively channel is shared fully.But, because under its situation that to be Channel Processing ability that 4 Channel Processing plates can provide still often can not satisfy the demands, just dispose other two Channel Processing plates, so just can not waste resource.And adopting fpga chip to realize on the circuit logic, and its main distinction with Fig. 3 is many two resource pool pool 4-5 and 3 groups add and, interpolation, filtering and time sequence adjusting circuit, and still, the interlock circuit structure of they and first group is identical.In fact, a fpga chip logic enough realizes n is carried 3 configurations of fanning (n≤3) forward direction circuit.In a word, the communicator that 3 years 3 of the present invention fan channels are shared fully is basic identical with the communicator hardware circuit that 2 years 3 fan channels are shared fully, just no longer detailed description here.
Fig. 9 is supported fan in 3 years 3 back to circuit diagram, just " 4+2 " two groups also have been divided into to data thereafter with shown in Figure 62 years 3 fan backs to the maximum difference of circuit, but, the back to data also all according to the corresponding relation of forward data link, give the particular port of corresponding CHU respectively.
Therefore, the communicator that Fig. 7 of the present invention-shown in Figure 93 years 3 fan channel is shared does not fully increase more device and circuit complexity when keeping flexibility of resource allocation, should be the communicator of present cost performance optimum.
Based on above-mentioned hardware configuration, apparatus of the present invention are furnished with corresponding allocation algorithm according to the load balancing resource, the operational processing unit on all the Channel Processing special chips in the unified dispatching device.When a new business application allocated channel is handled resource, resource scheduler is according to the continuous channel number of its needs, in the Resources list, search whether available resources are arranged, when on a plurality of Channel Processing special chips the resource that can meet the demands being arranged all, according to surplus resources phase approximately principle, this business priority allocation in the maximum Channel Processing special chip of residue processing unit, is guaranteed that load is in dynamic equilibrium on each Channel Processing plate.In the time of can guaranteeing before the power system capacity unsaturation (being to also have available channel bank CE in the system) like this, the resource bid of set of sectors whichsoever requires and can both be met, thereby realizes the forward link all functions that the many sector channel of multicarrier are shared fully.And the loaded service amount is more or less the same on all CHU plates, can not occur causing comprehensive inefficacy of certain sector service of system owing to some CHU plates break down.
The present invention has carried out implementing test in the base station equipment of applicant's development, this device is that utilization sign indicating number Taoist monastic name is distinguished the different channels in the same set of sectors.Therefore, in the device that complete channel is shared, how to support at the same time reverse cell in the monolithic Channel Processing special chip of a plurality of set of sectors work can distinguish the back mode that adopts to data the present invention of same sign indicating number Taoist monastic name in the different carrier frequency set of sectors be the input data of the reverse cell of control from which back to FPDP, then then bind with the carrier frequency sector to FPDP, after having determined the input port of cell data like this, just can determine the carrier frequency sector that this reverse cell is supported.The hardware logic of whole device verifies that test is successful on the base station platform of applicant's development, the functional test of sign indicating number territory and frequency domain is all passed through smoothly, has realized goal of the invention.
