Embodiment
For solving the problem that in prior art, carrier resource utilance is on the low side, in the embodiment of the present invention, RNC receives the public-measurement report that NodeB reports, and notes down and calculates the throughput of each H carrier wave in setting-up time.RNC sorts to the throughput of each H carrier wave in setting-up time accordingly, when RNC receives the request of PS service access, is accessed by carrier wave minimum for the throughput of prioritizing selection in setting-up time.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Consult shown in Figure 1A, in the embodiment of the present invention, the idiographic flow carrying out sorting with balanced to carrier wave is as follows:
The public-measurement report that step 100:RNC reports according to NodeB, calculates the throughput of each H carrier wave in setting duration respectively, and wherein, H carrier wave is the carrier wave of carrying HSDPA resource and the carrier wave of carrying HSUPA resource.
Consult shown in Figure 1B, in the embodiment of the present invention, the idiographic flow that RNC receives the public-measurement report of NodeB periodic report is as follows:
Step 1001:RNC sends public-measurement initialization request to NodeB;
Step 1002:NodeB sends public-measurement initialization response after receiving the request of RNC;
Step 1003:NodeB periodic report public-measurement is reported to RNC.
After community is successfully established, NodeB initiates bit rate (the High-Speed Downlink Shared Channel Provided Bit Rate provided for the high speed descending sharing channel of HSDPA resource, HS-DSCH Provided Bit Rate) public-measurement of type and the public-measurement of bit rate (Enhanced Dedicated Channel Provided Bit Rate, E-DCH Provided Bit Rate) type that provides for the enhancing dedicated channel of HSUPA resource.When NodeB performs this two classes public-measurement, periodic report mode will be taked by public-measurement report reporting to RNC, and reporting period is configurable.
RNC reports according to the public-measurement of the HS-DSCH Provided Bit Rate type for H carrier wave reported by NodeB, respectively by descending scheduling priority instruction (Scheduling Priority Indicator all on each H carrier wave, SPI) speed that correspondence reports adds up, as the HSDPA speed sum of corresponding H carrier wave.
SPI span is here 0 ~ 15,0 corresponding lowest priority, 15 corresponding limit priorities.When NodeB reports the measurement report of HS-DSCH Provided Bit Rate type, corresponding bit rate can be reported respectively for each descending SPI, the speed that descending SPI correspondences all on each H carrier wave report is added up, as the HSDPA speed sum of corresponding H carrier wave.
RNC reports according to the public-measurement of the E-DCH Provided Bit Rate type for H carrier wave reported by NodeB, adds up, the speed that up SPI correspondences all on each H carrier wave report as the HSUPA speed sum of corresponding H carrier wave respectively.
In like manner, when NodeB reports the measurement report of E-DCH Provided Bit Rate type, corresponding bit rate can be reported respectively for each up SPI, the speed that up SPI correspondences all on each H carrier wave report is added up, as the HSUPA speed sum of corresponding H carrier wave.
HSDPA speed sum corresponding for each H carrier wave and HSUPA speed sum are weighted according to the weighted factor preset by RNC respectively, obtain total speed sum of corresponding H carrier wave, and respectively using total speed sum of each H carrier wave as corresponding H carrier wave setting duration in throughput.Here total speed sum RateSum represents, the concrete throughput of some H carrier waves in setting-up time can be formulated as:
RateSum=HSDPA speed sum * weighted factor/100+HSUPA speed sum * (100-weighted factor)/100
Here default weighted factor is the integer between 0 to 100.
Step 110:RNC sorts to each H carrier wave based on the throughput of each H carrier wave in setting duration.
The throughput of each H carrier wave obtained by above-mentioned formulae discovery in setting duration arranges according to order from small to large by RNC, and wherein, the H carrier wave access priority that the throughput in setting duration is lower is higher.
When step 120:RNC receives packet switching PS data service access request, PS data service request is linked on the minimum H carrier wave of throughput in setting duration.
Like this PS user priority newly accessed is linked on the low H carrier wave of throughput, ensure that the Static Load of each carrier wave is balanced.
In addition, after a period of time, through the process such as release, adjustment of some users, such as user's active request adjusts to another H carrier wave of current area from certain H carrier wave of current area, or user is from the H carrier switch of current area to the H carrier wave another community, now may occur that the throughput of indivedual H carrier waves in setting-up time of community is higher, but the phenomenon that the throughput of other carrier wave in setting-up time is on the low side, therefore cause the unbalanced of carrier load.Under prior art, when the number of users on H carrier wave changes, RNC needs the dynamic equalization based on number of users on H carrier wave, each H carrier wave being carried out to carrier load, when the number of users that the minimum H carrier wave of the H carrier wave ratio number of users that under Ji Dang community, number of users is maximum has more exceedes certain predetermined thresholding, adjust to choosing certain or certain several user on the maximum carrier wave of number of users on the minimum carrier wave of number of users.But there is such a case, such as, although number of users is on the high side on the carrier wave of source, but major part is the data service lower to carrier resource demand, and although number of users is on the low side in target carrier, major part is the data service higher to carrier resource demand, does not so reach the effect of load balancing after adjustment, increase the weight of the unbalanced situation of load on the contrary, the problem such as cause the on the low side or user rate of the utilance of carrier resource not high.
In the embodiment of the present invention, RNC, according to the ranking results of throughput of each H carrier wave in setting duration, calculates the speed difference of wherein most high-throughput and minimum throughput, judges whether speed difference exceedes setting threshold; If so, at least one the PS user then chosen on throughput the highest H carrier wave adjusts on the minimum H carrier wave of throughput, otherwise do not need to carry out PS user's adjustment, RNC is by clear for imbalance state counter 0, and follow-up restarting is accumulated.
Preferably, wherein, when being judged as "Yes", RNC can adopt but be not limited to following two kinds of modes and carry out PS user's transfer between H carrier wave;
1) RNC is when judging that the speed difference of most high-throughput and minimum throughput exceedes setting threshold, and at least one the PS user directly chosen on throughput the highest H carrier wave adjusts on the minimum H carrier wave of throughput;
2) RNC is when judging that the speed difference of most high-throughput and minimum throughput exceedes setting threshold, under judging current area, H carrier wave is in imbalance state, and when the number of times judging that further H carrier wave under current area is in imbalance state reaches setting threshold, at least one the PS user chosen on throughput the highest H carrier wave adjusts on the minimum H carrier wave of throughput.
In use the 2nd) plant mode time, introduce the judgement to imbalance state, when the speed difference of most high-throughput and minimum throughput exceedes setting threshold, under then judging current area, H carrier wave is in imbalance state, imbalance state counter in RNC is by the number of times of the imbalance state of H carrier wave under current area cumulative 1, and whether the number of times that further judgement H carrier wave is in imbalance state reaches setting threshold, the number of times of imbalance state is here the continuous how many times load imbalance of H carrier wave under current area, also can be described as unbalance number of times, if unbalance number of times reaches the threshold value of setting, then RNC at least one PS user chosen on throughput the highest H carrier wave adjusts on the minimum H carrier wave of throughput, if unbalance number of times does not reach the threshold value of setting, only by unbalance number of times cumulative 1.
In addition, when being judged as "Yes", when RNC carry out between H carrier wave PS user transfer time, RNC can select that at least one priority on the highest carrier wave of the throughput in setting-up time is low and demand factor is larger PS user adjusts on the minimum carrier wave of throughput in setting-up time, to reaching the object of the dynamic equalization of H carrier load, improve the utilance of H carrier wave.
Consult shown in Fig. 2, the sequence that the embodiment of the present invention also provides for H carrier wave is as follows with balanced preferably idiographic flow:
Step 201:RNC sends public-measurement initialization request to NodeB, and NodeB sends public-measurement initialization response after receiving the request of RNC.
Step 202:NodeB periodic report public-measurement is reported to RNC.
Step 203:RNC receives the public-measurement report of all H carrier waves in one-period, and upgrades the total speed sum of each H carrier wave in setting-up time, i.e. the throughput of each H carrier wave in setting-up time.
Step 204:RNC sorts according to the throughput of each H carrier wave in setting duration, when RNC receives packet switching PS data service access request, is linked into by PS data service request on the minimum H carrier wave of throughput in setting duration.
Step 205:RNC, according to the ranking results of throughput of each H carrier wave in setting duration, calculates the speed difference of wherein most high-throughput and minimum throughput, and judges whether this speed difference exceedes setting threshold.If the speed difference of most high-throughput and minimum throughput exceedes setting threshold, perform step 206; If the speed difference of most high-throughput and minimum throughput is lower than setting threshold, perform step 209.
Step 206:RNC is by the load imbalance number of times of H carrier wave cumulative 1.
Step 207: if the speed difference of most high-throughput and minimum throughput exceedes setting threshold, then judge whether to exceed the unbalance number of times of setting, if meet the unbalance number of times requirement of setting, perform step 208; If do not meet the unbalance number of times requirement of setting, perform step 209.
Here unbalance number of times is the continuous how many times load imbalance of H carrier wave under community.
Step 208: if meet the unbalance number of times requirement of setting, then choose low and rate requirement the is larger PS user of a priority on throughput the highest H carrier wave and adjust on the minimum H carrier wave of throughput.
Step 209:RNC is by the load imbalance number of times clear 0 of H carrier wave under this community.
Sequence and the balanced adjustment of step 210:H carrier wave terminate.
By above-mentioned process, being adjusted on the minimum carrier wave of throughput by choosing low and rate requirement the is larger PS user of priority on the highest carrier wave of throughput, reaching the object of H carrier load dynamic equalization, improve the utilance of carrier resource.
