Description
Technical field
The present invention relates to wireless communication field, particularly wireless cellular network Mid Frequency distribution method.
Background technology
Mobile communication has changed people's life greatly, and along with the development of mobile communication and the growth of communication requirement, the user also improves day by day for the requirement of mobile network's quality.In mobile communication application personal mobile communication field the most widely, cellular mobile system has occupied leading status.
Wireless cellular network is divided into several cellular subcovering districts with whole service area, be called sub-district or honeycomb (Cell), each sub-district is covered with a transceiver, this transceiver is called base station (Base Station, be called for short " BS "), in the whole sub-district user all thus the base station finish communication.Because wireless cellular network can use identical frequency resource in different sub-districts, as shown in Figure 1, therefore only utilize narrower frequency band just can save frequency resource greatly for whole service area provides the mobile communication service.
Yet problem also produces thereupon, uses the network of same frequency resources for different districts, and the user who is in cell edge can be subjected to the interference from other adjacent cell, thereby the signal interference ratio of Cell Edge User can hang down.The simplest way of improving the cell edge signal interference ratio adopts channeling exactly.The channeling technology is meant that the wireless channel of same carrier frequency covers different districts, and these use between the sub-district of same carrier at intervals so that co-channel interference suppresses within the acceptable range.
In the early stage wireless cellular network, because anti-less, generally adopt looser frequency multiplexing mode with, the adjacent function of disturbing frequently.For example at total access communication system (the Total AccessCommunications System of Britain; be called for short " TACS ") and Advanced Mobile Phone System (the Advanced Mobile Phone System of the U.S.; be called for short " AMPS ") etc. in the analogue system; because signal adopts analogue modulation system; anti-fading and the signal demodulation ability is all relatively poor; so it is to protecting the requirement of thresholding also higher with frequency, generally greater than 18dB.Comparatively popular frequency multiplexing mode is 7/21 multiplexing in the TACS system, 7/21 multiplexing being (generally is divided into each base station 3 sub-districts) with all frequency average marks in cellular system in 21 sub-districts of 7 base stations, not reusing at these 21 sub-district intermediate-frequeney points, is that a topological structure is reused in whole network with these 21 sub-districts.From this relation everybody as can be seen the high carrier frequency configuration of each sub-district depend on two factors, the one, the frequency resource that operator had, the 2nd, the frequency multiplexing mode that when network design, is adopted.Take 7/21 to be multiplexed with example, high carrier frequency configuration=all frequency number/21, every sub-district.We also claim 21 to be frequency reuse, and it is a major parameter weighing a multiplexing loose degree of network.
At global mobile system (Global System of Mobility, be called for short " the GSM ") initial stage, comparatively popular is 4/12 frequency multiplexing mode afterwards, and 7/21 multiplexing comparing of this and TACS system had very big raising on the utilance of frequency resource.The multiplexing coefficient of 4/12 structure is 12, compares it with 21 and can dispose more carrier frequencies in each sub-district, thereby bigger capacity is provided on unit are.But it is one group with 4 base stations and reuses frequency, with 7/21 multiplexing the comparing with spacing distance is little frequently that with 7 base stations is a group.Gsm system why can adopt compact channeling technology to be because its adopts digital modulation technique, and signal is all much better than than analog signal aspect anti-fading, anti-interference.
Along with further developing of mobile communication technology, under the situation about acquiring a certain degree of the asthenia of signal, antijamming capability, as can be seen, wireless cellular network for rule, frequency reuse only need reach 3 just can guarantee that the frequency of any two neighbor cells use is all different, as shown in Figure 2, thereby can utilize limited frequency resource better, under the constant situation of the frequency resource that operator had, make each sub-district can dispose more carrier frequencies.
Nonetheless, each sub-district still is merely able to use 1/3 original frequency, and owing to use with minizone frequently every diminishing, presence of intercell interference increases, thereby further introduces this notion of Inter-Cell Interference Coordination.A basic scheme of Inter-Cell Interference Coordination is to manage at downlink resource, promptly between the sub-district, increase constraints (as to the structure of conventional channel and the scheduling of non-conventional channel) with coordination mode, time/frequency domain resource that these constraintss are normally available to explorer restriction, or to the restriction of the through-put power on certain time-frequency domain resources.
The Inter-Cell Interference Coordination technology mainly contains the frequency soft multiplexing technology.Frequency soft multiplexing claims partial frequency multiplexing again, the user who promptly is in each center of housing estate in the same mobile communications network can use identical frequency, but must be with lower power emission and reception, the user who is in each cell edge is the multiplexing method of frequency of utilization then, guarantees that two adjacent arbitrarily sub-districts use different frequencies.
That is to say that mobile communications network adopts frequency reuse greater than 1 for the more serious cell edge area of interference ratio, then be adopted as 1 frequency reuse in inside, sub-district.Being 3 to be example with the edge zone frequency reuse specifically, as shown in Figure 3, is 3 to divide frequencies according to multiplexing coefficient earlier, and each sub-district obtains dominant frequency separately, and for each sub-district, the frequency except its dominant frequency is called secondary frequency.That is to say that 2 the insides have just become secondary frequency to the dominant frequency of sub-district 1 in the sub-district.Usually, the available horsepower on the secondary frequency need be done some restrictions, accomplish lower than dominant frequency.The user of inside, sub-district can use dominant frequency arbitrarily or secondary frequently come transmitt or receive signal, and the user of cell edge can only use dominant frequency to come transmitt or receive signal, thereby has avoided the signal of Cell Edge User to be subjected to the interference of other sub-districts.
In actual applications, there is following problem in such scheme: the unicast service of the soft multiplex technique of frequency of utilization can't be compatible well with the common-frequency broadcasting multicast service.
Cause the main cause of this situation to be, because the clean culture frequency soft multiplexing need be divided the specified frequency resource, all frequency resources are divided into the dominant frequency and the secondary frequency of each sub-district, thereby do not leave frequency range and carry out broadcast multi-broadcasting for network side, and because broadcast multi-broadcasting is not frequent generation at network side, if be exclusively used in broadcast multi-broadcasting, can make resource to be utilized fully again from specified frequency resource division band segment.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of wireless cellular network and Mid Frequency distribution method thereof, makes more effectively to utilize limited frequency spectrum resources.
For achieving the above object, the invention provides a kind of wireless cellular network Mid Frequency distribution method, comprise following steps:
In the predeterminable area of forming by at least two neighbor cells, when network side carries out broadcast multi-broadcasting at needs, mark off band segment and carry out the common-frequency broadcasting multicast from the employed designated frequency band of this predeterminable area, clean culture is carried out in the interference coordination mode in each sub-district in this predeterminable area in the residue frequency range; When not needing to carry out broadcast multi-broadcasting, this designated frequency band is all distributed to interior each sub-district of this predeterminable area carry out clean culture in the interference coordination mode.
Wherein, describedly comprise the clean culture frequency soft multiplexing in the interference coordination mode.
In this external described method, when described network side carries out broadcast multi-broadcasting at needs, in described residue band limits, redistribute the major-minor frequency of the clean culture frequency soft multiplexing of each sub-district in the described predeterminable area.
In this external described method, when described network side carries out broadcast multi-broadcasting at needs, the band segment that directly takies in the described designated frequency band carries out the common-frequency broadcasting multicast, described in the residue frequency range in the predeterminable area clean culture frequency soft multiplexing major-minor dividing mode frequently of each sub-district consistent when not needing to carry out broadcast multi-broadcasting.
In this external described method, described designated frequency band adopts time division multiplexing mode to divide by timeslice, when described network side carried out broadcast multi-broadcasting at needs, in different timeslices, the band segment that uses for the common-frequency broadcasting multicast that directly takies was a part different in the described designated frequency band.
In this external described method, described designated frequency band adopts time division multiplexing mode to divide by timeslice, when described network side carries out broadcast multi-broadcasting at needs, only the part-time sheet of the band segment that marks off from described designated frequency band, carry out the common-frequency broadcasting multicast, carry out clean culture in the interference coordination mode in the sheet in the remaining time of this band segment.
In this external described method, have at least and overlap if carry out the dominant frequency of shared broadcast multi-broadcasting frequency range in the sub-district of common-frequency broadcasting multicast and adjacent pure clean culture sub-district, the dominant frequency of lap that then will this pure clean culture sub-district changes into frequently secondary.
The present invention also provides a kind of wireless cellular network, comprises at network side:
Decision-making module is used to judge whether to carry out broadcast multi-broadcasting;
The frequency allocation module is used for the employed designated frequency band of the predeterminable area of being made up of at least two neighbor cells is distributed unitedly;
Described decision-making module is judged in the time of need carrying out broadcast multi-broadcasting, indicates described frequency allocation module to mark off band segment from described designated frequency band and carries out the common-frequency broadcasting multicast, and clean culture is carried out in the interference coordination mode in each sub-district in this predeterminable area in the residue frequency range; Described decision-making module is judged when not needing to carry out broadcast multi-broadcasting, indicates described frequency allocation module that this designated frequency band is all distributed to interior each sub-district of this predeterminable area and carries out clean culture in the interference coordination mode.
By relatively finding that the main distinction of technical scheme of the present invention and prior art is, only when needs carry out broadcast multi-broadcasting, mark band segment and carry out the common-frequency broadcasting multicast, the residue frequency range is carried out clean culture in the Inter-Cell Interference Coordination mode.This scheme has realized the dynamic combination of broadcast multi-broadcasting and clean culture can more effectively utilizing limited frequency spectrum resources in same frequency range.
The residue frequency range can be distributed in the interference coordination mode again in each minizone, and the method for salary distribution in the time of also can keeping not needing to carry out broadcast multi-broadcasting is constant.With the clean culture frequency soft multiplexing is example, and the scheme of redistributing can make the major-minor resource allocation frequently of each sub-district relatively more balanced, keeps the scheme of the former method of salary distribution can avoid repartitioning continually the expense that major-minor brings frequently.
Can also carry out time division multiplexing to above-mentioned frequency range, the part-time sheet of a distribution portion frequency range returns the common-frequency broadcasting multicast to use, and all timeslices in the sheet At All Other Times of this band segment and the residue frequency range all return the clean culture frequency soft multiplexing to use.After adopting this time division multiplexing, can control the shared frequency resource of broadcast multi-broadcasting more neatly.
If the method for salary distribution when the residue frequency range keeps not needing to carry out broadcast multi-broadcasting is constant, and has adopted time division multiplexing, can adopt frequency hopping, promptly each occurs that the shared frequency range of common-frequency broadcasting multicast is different in the timeslice of common-frequency broadcasting multicast.Can prevent because some sub-district that the bandwidth ratio broad that broadcast multi-broadcasting takies causes does not have the situation of dominant frequency on the broadcast multi-broadcasting timeslice by frequency hopping, make that the throughput of each cell edge is comparatively balanced generally.
If carrying out the dominant frequency of shared broadcast multi-broadcasting frequency range in the sub-district of common-frequency broadcasting multicast and adjacent pure clean culture sub-district has at least and overlaps, the dominant frequency of lap that then will this pure clean culture sub-district changes into frequently secondary, thereby avoids interfering with each other between broadcast multi-broadcasting and the clean culture dominant frequency.

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, in the predeterminable area of forming by at least two neighbor cells, when network side carries out broadcast multi-broadcasting at needs, mark off band segment and carry out the common-frequency broadcasting multicast from the employed designated frequency band of this predeterminable area, clean culture is carried out in the interference coordination mode in each sub-district in this predeterminable area in the residue frequency range; When not needing to carry out broadcast multi-broadcasting, this designated frequency band is all distributed to interior each sub-district of this predeterminable area carry out clean culture in the interference coordination mode.Wherein, the interference coordination mode can be the clean culture frequency soft multiplexing.
According to inventive principle, first embodiment of the invention wireless cellular network Mid Frequency distribution method is described below.
As shown in Figure 4, in step 410, network side distributes the dominant frequency and the secondary frequency of the clean culture frequency soft multiplexing of each sub-district in the predeterminable area in the designated frequency band scope.Such as in the designated frequency band scope, network side is three adjacent cell allocation dominant frequency in the same predeterminable area, is respectively dominant frequency 1, dominant frequency 2 and dominant frequency 3, and the frequency in the designated frequency band except that its dominant frequency is the frequently secondary of this sub-district, as shown in Figure 5.
Then enter step 420, network side is judged the current broadcast multi-broadcasting that whether needs to carry out, then enter step 440 if desired, do not need then to enter step 430, the subscriber equipment of each sub-district carries out the clean culture frequency soft multiplexing frequently according to the major-minor of distributing in the predeterminable area, afterwards, return step 420, continue to judge the current broadcast multi-broadcasting that whether needs to carry out.
In step 440, network side need carry out broadcast multi-broadcasting, divides band segment and carry out the common-frequency broadcasting multicast in the designated frequency band scope.
Then enter step 450, network side is redistributed the dominant frequency and the secondary frequency of the clean culture frequency soft multiplexing of each sub-district in the predeterminable area in the residue band limits.At above-mentioned example shown in Figure 5, in identical band limits, network side is divided band segment as the broadcast multi-broadcasting frequency band, and remaining frequency range is divided into three frequency ranges again, distribute to three original sub-districts respectively as its dominant frequency, equally, other frequencies in the residue frequency range except that dominant frequency are the frequently secondary of this sub-district, as shown in Figure 6.
Because in real network, some content may only need be carried out broadcast multi-broadcasting in the part sub-district, can not consider the existence of broadcast multi-broadcasting this moment for the adjacent pure clean culture sub-district, sub-district of carrying out broadcast multi-broadcasting with needs, according to soft multiplexing being configured of normal clean culture, yet this method may cause interfering with each other on the cell edge.
Then enter step 460, the subscriber equipment of each sub-district carries out the clean culture frequency soft multiplexing frequently according to the major-minor of redistributing in the predeterminable area.
By when needs carry out broadcast multi-broadcasting, from original frequency range, mark off part and carry out broadcast multi-broadcasting, and in the residue frequency range in this predeterminable area each sub-district carry out clean culture in the frequency soft multiplexing mode, make that clean culture frequency soft multiplexing and broadcast multi-broadcasting can be in the dynamic combinations of same frequency range, when not increasing extra resource, neither influence the clean culture frequency soft multiplexing, can carry out the broadcast multi-broadcasting of network side again, effectively utilized limited frequency spectrum resources.
Second embodiment of the invention wireless cellular network Mid Frequency distribution method, as shown in Figure 7, step 710-730 and step 410-430 are similar, do not repeat them here.
In step 740, network side need carry out broadcast multi-broadcasting, the band segment that network side directly takies in the designated frequency band carries out the common-frequency broadcasting multicast, in the residue frequency range in the predeterminable area clean culture frequency soft multiplexing major-minor dividing mode frequently of each sub-district consistent when not needing to carry out broadcast multi-broadcasting.Such as, before the network side is three dominant frequency that neighbor cell allocation is different of same predeterminable area, be respectively dominant frequency 1, dominant frequency 2 and dominant frequency 3, when needs carry out broadcast multi-broadcasting, as shown in Figure 8, network side directly takies all frequency ranges of dominant frequency 3 and the band segment of dominant frequency 2 carries out the common-frequency broadcasting multicast, and the clean culture frequency soft multiplexing major-minor dividing mode frequently of each sub-district is constant in the residue frequency range.Thereby avoided because of repartitioning the expense that major-minor brings frequently continually.
Then enter step 750, the major-minor of network side change respective cell frequently.Specifically, can not be used further to clean culture owing to be broadcasted the frequency that multicast takies, therefore network side no longer allows the sub-district to use this part frequency as dominant frequency or frequently secondary, and, originally this part frequency as the sub-district of dominant frequency can not be again it as dominant frequency, network side is that the major-minor of each sub-district is done corresponding change frequently in the predeterminable area.
Then enter step 760, the subscriber equipment of each sub-district carries out the clean culture frequency soft multiplexing frequently according to the major-minor after changing in the predeterminable area.Afterwards, return step 720, continue to judge the current broadcast multi-broadcasting that whether needs to carry out.
Third embodiment of the invention wireless cellular network Mid Frequency distribution method is big to identical with first execution mode, its difference only is, in the present embodiment, designated frequency band adopts time division multiplexing mode to divide by timeslice, when network side carries out broadcast multi-broadcasting at needs, only the part-time sheet of the band segment that marks off from designated frequency band, carry out the common-frequency broadcasting multicast, remain unchanged in the sheet according to the major-minor frequency of original distribution, adopt frequency soft multiplexing to carry out clean culture in the remaining time of this band segment.
Such as, when network side carries out broadcast multi-broadcasting at needs, in the designated frequency band scope, divide band segment, and in the residue band limits, the dominant frequency of redistributing the clean culture frequency soft multiplexing of each sub-district in the predeterminable area is with frequently secondary as the broadcast multi-broadcasting frequency range.Afterwards, only in the odd number timeslice, network side carries out the common-frequency broadcasting multicast with the broadcast multi-broadcasting frequency, and simultaneously, the user of each sub-district carries out the clean culture frequency soft multiplexing frequently according to the major-minor of redistributing in the predeterminable area; And in the even numbers timeslice, network side does not carry out the common-frequency broadcasting multicast, and the user of each sub-district still carries out the clean culture frequency soft multiplexing frequently according to original major-minor that distributes in the predeterminable area.
The four embodiment of the invention wireless cellular network Mid Frequency distribution method and second execution mode are roughly the same, its difference only is that designated frequency band adopts time division multiplexing mode to divide by timeslice, when network side carries out broadcast multi-broadcasting at needs, in different timeslices, the band segment that uses for the common-frequency broadcasting multicast that directly takies is to specify different part in the frequency range, just the band segment that uses for the common-frequency broadcasting multicast is carried out frequency hopping and handles.
Such as, before the network side three dominant frequency that neighbor cell allocation is different in the identical predeterminable area, be respectively dominant frequency 1, dominant frequency 2 and dominant frequency 3, when needs carry out broadcast multi-broadcasting, as shown in Figure 9, in timeslice 1, network side directly takies all frequency ranges of dominant frequency 1 and the band segment of dominant frequency 2 carries out the common-frequency broadcasting multicast, and in timeslice 2, network side directly takies all frequency ranges of dominant frequency 2 and the band segment of dominant frequency 3 carries out the common-frequency broadcasting multicast, afterwards, in timeslice 3, network side directly takies all frequency ranges of dominant frequency 3 and the band segment of dominant frequency 2 carries out the common-frequency broadcasting multicast.Carry out the common-frequency broadcasting multicast by taking different frequency range at the different time sheet, can prevent that some sub-district that causes because of the bandwidth ratio broad that broadcast multi-broadcasting takies from not having the situation of dominant frequency on the broadcast multi-broadcasting timeslice, make that the throughput of each cell edge is comparatively balanced generally.
The fifth embodiment of the invention wireless cellular network Mid Frequency distribution method and second to the 4th execution mode are roughly the same, its difference only is, in the present embodiment, whether the dominant frequency of broadcast multi-broadcasting frequency range that the sub-district that network side needs further judgement to carry out the common-frequency broadcasting multicast is shared and adjacent pure clean culture sub-district overlaps, if overlap, the dominant frequency of lap that then will this pure clean culture sub-district changes into frequently secondary.Such as, broadcast multi-broadcasting is carried out in three sub-districts of network side in predeterminable area, take band segment in the designated frequency band as the broadcast multi-broadcasting frequency range, at this moment, network side needs further to judge whether the dominant frequency of the pure clean culture sub-district of adjacent area overlaps with this broadcast multi-broadcasting frequency range, if having then lap dominant frequency that will this pure clean culture sub-district changes the pair frequency into.Thereby avoid interfering with each other between broadcast multi-broadcasting and the clean culture dominant frequency.
The wireless cellular network of sixth embodiment of the invention, comprise and be used to judge whether to carry out the decision-making module of broadcast multi-broadcasting, and be used for frequency allocation module that the employed designated frequency band of the predeterminable area of being made up of at least two neighbor cells is distributed unitedly.
Specifically, network side is judged the current broadcast multi-broadcasting that whether needs to carry out by decision-making module, if judging, decision-making module need carry out broadcast multi-broadcasting, then indicate the frequency allocation module from designated frequency band, to mark off band segment and carry out the common-frequency broadcasting multicast, and in the residue frequency range in this predeterminable area each sub-district carry out clean culture in the interference coordination mode; Do not need to carry out broadcast multi-broadcasting if decision-making module is judged, then indicate the frequency allocation module that this designated frequency band is all distributed to interior each sub-district of this predeterminable area and carry out clean culture in the interference coordination mode.
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.
