Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
TD-LTE communication system not only has the feature of two-forty, low time delay, and has the bandwidth of flexibility and changeability, specifically can carry 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz bandwidth carrier and carry out transfer of data.And the physical layer Basic Transmission Unit of TD-LTE system is Resource Block RB, RB number corresponding to different carrier bandwidths is not quite similar.In data transmission procedure, and not all RB can be occupied, and adopt the RB quantity taken to be RB resource utilization divided by the RB total quantity under this carrier wave, this index can read from main equipment.
Prior art, for TD-LTE system, adopts macro station directly high flow capacity community to be carried out to the method reply tidal effect of carrier wave dilatation usually.First build up TD-LTE first phase network, be configured to 20MHz single carrier for each community is unified, then in network operation process, carrier wave dilatation carried out to high flow capacity community.Such as, after building up first phase network, in network actual motion, there is serious network congestion in certain market of central business district CBD daytime, hour downlink throughput capacity of congested cells (A community) reaches 7.3 × 10
9byte.The RB resource utilization of A community as shown in Figure 1, the same day 8,9,10,11,13,16,23 RB resource utilizations have all exceeded 50%, this community belongs to high flow capacity Hot Spot.In next period TD-LTE network engineering, directly the dilatation of 20MHz carrier wave is carried out to A community.But A community except 8,9,10,11,13,16,23 time periods that several resource utilization is higher, all the other time periods do not need to carry out carrier wave dilatation, although therefore the method solves the network congestion problem of Hot Spot, inevitably bring the problem of carrier wave redundancy.
Possess energy-saving and emission-reduction, focus on, the Radio Access Network C-RAN technology of collaboration type radio and cloud computing ability can realize carrier resource and share, thus realize the dynamic adaptation of carrier resource.But C-RAN technology is usually used in global system for mobile communications GSM and TD SDMA TD-SCDMA system.
The method of the network resource planning of the embodiment of the present invention, can be applicable to the TD-LTE system with the C-RAN network architecture, the characteristic of TD-LTE system a scalable network bandwidth and C-RAN can be shared and the characteristic that dynamic allocates carrier wave organically combines, and to utilize RB resource utilization to plan carrier resource.Achieve the real-time dynamic adaptation of carrier resource, efficiently solve the problem that tidal effect causes, and the carrier wave redundancy occurred after avoiding dilatation, farthest ensure that resource utilization.
As shown in Figure 2, the method for the network resource planning of the embodiment of the present invention, comprising:
Step 11, periodically detects the carrier resource configuration data of network Xia Ge community to be planned, and described network to be planned is can the network of centralization process, and described network to be planned comprises base band resource pool, and described base band resource pool comprises default multiple carrier resource;
Step 12, obtains the carrier resource utilance of each community according to described carrier resource configuration data;
Step 13, judges whether described carrier resource utilance exceeds preset range, obtains judged result;
Step 14, when described judged result is for being, judge to need the community corresponding to described carrier resource utilance to carry out resource adjustment, to make the carrier resource utilance after adjustment in described preset range, and according to the carrier resource in described base band resource pool and described judged result, obtain adjustment data;
Step 15, according to described adjustment data, re-starts planning to the carrier wave configuring condition of described network Xia Ge community to be planned.
The method of the network resource planning of the embodiment of the present invention, by periodically detecting carrier resource configuration data and the carrier resource utilance of network to be planned, and by the carrier resource in base band resource pool, dynamic adaptation is carried out, to control carrier resource utilance in preset range to carrier wave configuration.Achieve the real-time dynamic adaptation treating planning network each cell carrier resource, efficiently solve the problem that tidal effect causes, and the carrier wave redundancy occurred after avoiding dilatation.
Wherein, in above-mentioned steps 11, predetermined period can be one hour, one week or one day etc.

Step 141, judges to need the community corresponding to described carrier resource utilance to carry out carrier resource release in limited time lower than the lower of described preset range in described carrier resource utilance, and according to the carrier resource in described base band resource pool, obtains release data;
Step 142, judges to need the community corresponding to described carrier resource utilance to carry out carrier resource dilatation higher than the upper of described preset range in described carrier resource utilance in limited time, and according to the carrier resource in described base band resource pool, acquisition dilatation data;
The lower limit of wherein said preset range is less than the upper limit of described preset range.
Now, prescribe a time limit lower than the lower of preset range in carrier resource utilance, carrier wave release is carried out to community; Prescribe a time limit higher than the upper of preset range in carrier resource utilance, carrier wave dilatation is carried out to community, effectively can control carrier resource utilance in preset range, to solve the network congestion that tidal effect causes, achieve the real-time dynamic adaptation of carrier resource.
Wherein, can also comprise before the step of above-mentioned steps 15:

12, a
13], wherein a
11for cell ID, a
12for carrier bandwidths, a
13for carrier resource utilance, wherein a
13∈ [0%, 100%].
Reevaluate the carrier resource demand of each community, structure carrier wave dilatation table and carrier wave free list.As shown in Figure 4, the lower limit r of preset range and the upper limit R of preset range can be preset, wherein 0%≤r<R≤100%, then read the element a in carrier resource utilance matrix
13, then judge a by above-mentioned steps 13
13whether between r and R.Then by step 141, at a
