Embodiment
Basic thought of the present invention is: be set to the frequency sharing district by a plurality of residential quarters, all frequency resources in the dynamic frequency resource pool are shared in each residential quarter in this frequency sharing district, when each residential quarter needs to load carrier frequency owing to professional increase, from dynamic frequency resource pond, choose frequency and the loading disturbing minimum unallocated frequency or distributed to other residential quarters in the frequency sharing district, when professional minimizing need to be closed carrier frequency in the residential quarter, this close will be identified as when frequency corresponding to carrier frequency used by other residential quarters unallocated, in order to load for other residential quarters.
For making purpose of the present invention, technical scheme and advantage are clearer, and by the following examples and with reference to accompanying drawing, the present invention is described in more detail.Below explanation only is exemplary, rather than in order to limit protection scope of the present invention and application thereof.
Among the present invention, be a frequency sharing district with some cell configuration.The frequency sharing district is the cell area that the service-user total amount is relatively stable, service-user moved in described frequency sharing district with the period, for example aforesaid morning and evening tides traffic related cell.Among the present invention, generally be to have the cell configuration of morning and evening tides traffic in same frequency sharing district.In addition, the frequency sharing district is the zone that adjacent cell forms, and also can serve as reasons mutual is not the zone of the residential quarter composition of adjacent cell.The present invention need to construct one and offer the dynamic frequency resource pool that use each residential quarter in the frequency sharing district, interferometry is periodically carried out to the frequency in the dynamic frequency resource pool in the residential quarter, obtain thus usable frequency collection separately, when needs load new frequency, concentrate from usable frequency and select suitable frequency and use, realize the maximization of frequency resource utilization ratio.Among the present invention, the dynamic frequency resource pool can be set up take each residential quarter as unit, is in the frequency sharing district each residential quarter and sets up respectively the dynamic frequency resource pool, and the frequency sharing district group that also can consist of take a plurality of residential quarters is set up the dynamic frequency resource pool as unit.
Fig. 1 is dynamic frequency resource pool schematic diagram, as shown in Figure 1, frequency in the dynamic frequency resource pool among the present invention can be divided into four kinds of different states, be respectively: unallocated down state, unallocated upstate, distribute down state and distributed upstate, wherein, unallocated down state is, frequency is not assigned with and disturbs and do not satisfy threshold requirement, and the frequency of this state can not be assigned with.Unallocated upstate is, frequency is not assigned with and disturbs and satisfies threshold requirement, and the frequency of this state can be assigned with.Distributed down state to be, frequency has been assigned with and has disturbed and do not satisfy threshold requirement, and the frequency of this state can not be assigned with.Distributed upstate to be, frequency has been assigned with and has disturbed and satisfy threshold requirement, and when all usable frequencies all were assigned with, the frequency of this state just can be assigned with.
The state of frequency needs periodically to determine.When base station BTS is in initial condition, at first the frequency of high priority TCH frequency carried out preassignment, and with these frequency state never distribution state be adjusted into distribution state.Then the residential quarter begins all frequencies in the dynamic frequency resource pool are carried out interferometry, when frequency interferences satisfies threshold requirement, then puts into the usable frequency of this residential quarter and concentrates.
When the residential quarter needs to load carrier frequency owing to professional increase, concentrate the frequency that is in unallocated state of selecting the interference minimum to load from usable frequency, and with the state of frequency never distribution state be adjusted into distribution state, if usable frequency concentrates all frequencies all to be used, then select and disturb the minimum frequency of distributing to other residential quarters to load.
Because professional minimizing need to close corresponding carrier frequency the time, corresponding frequency is not used by other residential quarters if this closes carrier frequency when the residential quarter, and the state of then this being closed frequency then is adjusted into unallocated state from distribution state.
Fig. 2 is six cell topology schematic diagrames of morning and evening tides traffic, and as shown in Figure 2, showing 6 residential quarters (residential quarter 1 to residential quarter 6) is the example in a frequency sharing district, and when supposing that each residential quarter carried out the frequency static configuration, each residential quarter need configure 5 TCH carrier frequency.Like this, the TCH carrier frequency of 6 residential quarters needs to use 30 frequencies altogether.And during practical application, because morning and evening tides traffic phenomenon, 4 TCH carrier frequency only need be opened in average every residential quarter, use 24 frequencies to satisfy the demands.Below in conjunction with the frequency configuration situation of residential quarter shown in Figure 2, further illustrate the essence of technical solution of the present invention.
Fig. 3 is the flow chart of the frequency spectrum resource collocation method of the embodiment of the invention, and as shown in Figure 3, frequency spectrum resource collocation method of the present invention specifically may further comprise the steps:
Initialization static configuration network B CCH and high priority TCH carrier frequency frequency; Suppose that each residential quarter has 1 BCCH carrier frequency and 2 TCH carrier frequency to carry out static frequency configuration.And system has used 24 TCH frequencies altogether, but residential quarter 1 static configuration frequency is that { 1,7}, residential quarter 2 is that { 3,9}, residential quarter 3 is that { 6,12}, residential quarter 4 is that { 5,11}, residential quarter 5 is that { 2,8}, residential quarter 6 is { 4,10}.
Step 301: for each residential quarter makes up the frequency resource pond, the below is take the construction process of six residential quarters dynamic frequency resource pool of the present invention as example illustrates of topological structure shown in Figure 2, at first according to the geographical position of residential quarter, and the morning and evening tides telephone traffic characteristic, with little three the frequency sharing district groups of dividing into shown in Figure 2, be respectively: (1,5), (2,6), (3,4), wherein, the every a pair of subdistrict position in the frequency sharing district group is non-conterminous.After determining the shared frequencies cell set, just can be each shared frequencies set constructor frequency resource pond in accordance with the following steps:
A) initiation parameter i=0, j=0, p=0, n=shared frequencies group number, m=shared frequencies residential quarter sum, C
kResidential quarter number among the=shared frequencies group k;
B) make j=1, i=1, p=1 is assigned to shared frequencies group j with i frequency;
C) i=i+1, if i＞system's sum frequency number, then algorithm finishes;
D) judge following condition:
If i-(p-1) * m is less than or equal to
I frequency is assigned to shared frequencies group j, execution in step c;
If i-(p-1) * m greater than
Then jump to step e;
E) j=j+1, judge following condition:
If j is less than or equal to n, i frequency is assigned to shared frequencies group j, execution in step c;
If j, jumps to step f greater than n;
F) p=p+1, j=1 is assigned to shared frequencies group j, execution in step c with i frequency.
Perhaps, also can distribute frequency by following mode:
First round frequency point allocation process: frequency 1,2 is distributed to shared frequencies district group 1, and frequency 3,4 is distributed to shared frequencies district group 2, and frequency 5,6 is distributed to shared frequencies district group 3;
Second takes turns the frequency point allocation process: frequency 7,8 is distributed to shared frequencies district group 1, and frequency 9,10 is distributed to shared frequencies district group 2, and frequency 11,12 is distributed to shared frequencies district group 3;
……
Fourth round frequency point allocation process: frequency 19,20 is distributed to shared frequencies district group 1, and frequency 21,22 is distributed to shared frequencies district group 2, and frequency 23,24 is distributed to shared frequencies district group 3.
The dynamic frequency resource pool that finally obtains shared frequencies district group 1 is { 1,2,7,8,13,14,19,20}, the frequency resource pond of shared frequencies district group 2 is { 3,4,9,10,15,16,21,22}, the frequency resource pond of shared frequencies district group 3 is { 5,6,11,12,17,18,23,24}.Its intermediate-frequeney point 1～12 distributes in step 1.
Step 302 judges whether the computing cycle of usable frequency collection arrives.
When the computing cycle of usable frequency collection arrives, each frequency in the dynamic frequency resource pool is disturbed definite, determined current usable frequency collection, to upgrade the current usable frequency collection of this residential quarter.
Step 303 is upgraded the disturbed condition of each frequency according to the interference calculation algorithm.
Each residential quarter is measured the disturbed condition of each frequency in the dynamic frequency resource pool in real time, and periodically calculates its usable frequency collection.When a usable frequency collection computing cycle arrived, the disturbed condition of each frequency was at first calculated in the residential quarter according to the result who measures.
A method calculating each frequency interferences situation is to bring calculating according to uplink interference.Because the base station can periodically be measured the uplink interference band of idle channel, therefore can when measuring the idle channel interference fringe, scan the disturbed condition that obtains them to dynamic frequency resource pool medium frequency, each frequency interferences situation adopts the mean value of 8 channel disturbance band grades to characterize, when surpassing certain threshold, the interference fringe rank of frequency just thinks that this frequency is unavailable, and do not put into residential quarter usable frequency collection, usable frequency is put into the usable frequency collection successively by interference fringe grade order from small to large.
The up-downgoing disturbed condition of this residential quarter that also can be reported by mobile phone for measuring and each frequency of BCCH level estimation of abutting subdistrict.
Among the present invention, disturbed condition definite as shown in table 1.
Step 304 is upgraded residential quarter usable frequency collection.
Threshold requirement shown in interference calculation result and the table 1 is compared, when frequency interferences meets the demands, then put into the usable frequency collection.By calculating periodically the disturbed condition of each frequency in the dynamic frequency resource pool, can determine in time which frequency is to belong to the frequency that this residential quarter can be used in the attitude frequency resource pond.
Table 1
Whether step 305 has the residential quarter need to close carrier frequency.
In the time of need to closing carrier frequency when the residential quarter because the variation of telephone traffic such as current business reduce, the state that then needs this to be closed the carrier frequency respective frequencies upgrades.
Step 306 determines whether the frequency that other residential quarters use this to close.
Step 307 is " unallocated " with this status indication of closing frequency.
If determining does not have other frequencies to use this to close frequency in the frequency sharing district, the status indication of then this being closed frequency is " unallocated "
Step 308 has determined whether that the residential quarter loads new carrier frequency.
When needing to load carrier frequency because business demand such as business increase when the residential quarter, concentrate the frequency of searching " unallocated " that disturb minimum to load from usable frequency, and the new frequency state of changing this loading is " distributing ", if it all is " distributing " state that usable frequency is concentrated all frequencies, then selects and disturb the minimum current frequency of distributing to other residential quarters to load.Also namely, the frequency that each residential quarter can use mutually other residential quarters to load in the frequency sharing district, this is owing to each residential quarter in the frequency sharing district is not adjacent cell, the interference less that uses identical frequency to bring mutually.
Dynamic frequency resource pool of method construct of the present invention is selected suitable frequency to frequency dynamic in the system and is used from this dynamic frequency resource pool in sum.After using technical scheme of the present invention, the frequency number that each TCH frequency of frequency sharing district takies is 24, several 30 of the acquisition frequency when not using technical solution of the present invention, thus realized spectrum saving.
