Fig. 2 is the flow chart of the method for the adjustment carrier frequency point of the embodiment of the present invention two.As shown in Figure 2, the method comprises following process.
The RTWP of the original candidates target frequency of step 201:NB monitoring configuration.
Step 202:NB obtains the community ID from the community to be adjusted of RNC.
Step 203:NB, according to the RTWP of the community ID of community to be adjusted, the target frequency RTWP thresholding of configuration and original candidates target frequency, selects current candidate target frequency from the original candidates target frequency of configuration.
Step 204:NB reports current candidate target frequency to RNC, and to make RNC according to target frequency selection strategy, select target frequency from current candidate target frequency, adjusts to target frequency by carrier wave to be adjusted.
In the embodiment of the present invention two, NB monitors the RTWP of original candidates target frequency, obtain the community ID of community to be adjusted from RNC, select current candidate target frequency according to above-mentioned monitored results and community ID and report RNC, carrying out carrier frequency point adjustment to make RNC select target frequency.Thus NB can obtain candidate target frequency by monitoring RTWP, when carrier performance is deteriorated, NB reports candidate target frequency according to the triggering of RNC, thus make RNC and NB independently can complete frequency adjustment, avoid and adjust the discovery that causes manually not in time and the long defect of artificial adjustment process holding time, therefore improve the real-time of poor performance carrier wave being carried out to frequency adjustment.
Fig. 3 is the flow chart of the method for the adjustment carrier frequency point of the embodiment of the present invention three.As shown in Figure 3, the method comprises following process.
Step 301:RNC judges whether to open carrier frequency point adjustment.
If so, step 302 is performed, otherwise, repeated execution of steps 301.
Step 302:RNC sends to NB and opens carrier frequency point adjustment notification message.
In this step, RNC sends to NB and opens carrier frequency point adjustment notification message, and NB obtains the unlatching carrier frequency point adjustment notification message from RNC.
After step 302, RNC performs step 303 to step 307, and NB performs step 308.Particularly, step 308 can perform between step 302 and step 303, also can perform between step 307 and step 309, can also perform any time in the process of step 303 to step 307, in this embodiment, be only explained to perform step 308 after step 307.
Step 303:RNC starts carrier frequency point adjustment timer.
Step 304:RNC monitors the performance index of the carrier wave of community to be adjusted.
In this step, the above-mentioned performance index adopted in monitor procedure can be any indexs relevant to carrier performance.Such as, for all types of carrier wave, above-mentioned performance index all can to adopt in carrier wave measurement period the call drop accounting of average RAB every day (Radio Access Bear is called for short RAB) number or radio open reason.Particularly, in carrier wave measurement period every day average RAB number be in measurement period frequency RAB sum divided by measurement period number of days.The call drop accounting of radio open reason is that this carrier wave wireless eats dishes without rice or wine the quantity of reason call drop divided by this frequency call drop sum, the call drop that reason of eating dishes without rice or wine causes comprises wireless link (Radio Link is called for short RL) and sets up the call drop and the overtime call drop caused of various downlink signaling that unsuccessfully cause.On this basis, for the carrier wave of R4 type, above-mentioned performance index can also adopt uplink special physical channel (Dedicated Physical Channel, be called for short DPCH) slot interfering signal of time code power (Interference Signal Code Power is called for short ISCP) strong jamming accounting.Particularly, up DPCH time slot ISCP strong jamming accounting is the total degree that the number of times reporting ISCP to be greater than the strong ISCP thresholding in backstage in measurement period reports divided by this frequency ISCP.For the carrier wave of high-speed slender body theory (High SpeedDownlink Packet Access is called for short HSDPA) type, above-mentioned performance index can also adopt cell update ratio.Particularly, cell update ratio is that cell update number of times is divided by RAB number.For high speed uplink packet access (High Speed Uplink Packet Access, be called for short HSUPA) carrier wave of type, above-mentioned performance index can also adopt and strengthen uplink physical channel (Enhance Physical UplinkChannel is called for short E-PUCH) ISCP strong jamming accounting.Particularly, E-PUCH ISCP strong jamming accounting is the total degree that number of times that the E-PUCH ISCP reported in measurement period is greater than the strong ISCP thresholding in backstage reports divided by this frequency ISCP.In actual applications, can be used alone above-mentioned performance index, also any more than two or two in above-mentioned performance index can be combined, and, above-mentioned performance index are only some instantiations of the performance index carrying out monitoring, and can also monitor in actual applications to other performance index.
Step 305:RNC judges that whether carrier frequency point adjustment timer is overtime.
If so, step 306 is performed; Otherwise, return step 304.
Step 306: when carrier frequency point adjustment timer expiry, RNC, according to the performance index of the carrier wave of default ordering strategy, default adjustment number of carriers and community to be adjusted, selects carrier wave to be adjusted from the carrier wave of community to be adjusted.
In this step, particularly, the ordering strategy preset comprises: according to performance index sequence from difference to excellent order, and, for at least two carrier waves belonging to same community to be adjusted, select a carrier wave according to the principle that subcarrier is preferential and/or the poorest carrier wave of performance is preferential.Correspondingly, the detailed process of step 306 comprises: RNC according to performance index from difference to excellent order, select the carrier wave belonging to different community to be adjusted respectively of default adjustment number of carriers, for at least two carrier waves belonging to same community to be adjusted, select a carrier wave according to the principle that subcarrier is preferential and/or the poorest carrier wave of performance is preferential.
For the performance index introduced in above-mentioned steps 304, then within step 306, specifically can adopt following method choice carrier wave to be adjusted: the first step, preset frequency adjustment average RAB number thresholding every day, from the carrier wave of community to be adjusted, filter out every day average RAB number be less than the carrier wave of this pre-determined threshold.Second step, sorts according to the call drop accounting order from high to low of radio open reason.When sorting, if the carrier wave that the call drop accounting that there is radio open reason is identical, then according to following principle process: for R4 carrier wave, sort according to up DPCH time slot ISCP strong jamming accounting order from high to low; For HSDPA carrier wave, with the RAB sum of the number of times of this carrier wave generation cell update divided by this carrier wave, the result order from high to low according to above-mentioned division calculation sorts; For HSUPA carrier wave, sort according to up EPUCH ISCP strong jamming accounting order from high to low; If during according to above-mentioned performance index sequence, still there are two or more carrier waves that performance index value is identical, namely there is situation arranged side by side in the ranking, then to carrier wave arranged side by side, sort according to the carrier wave ID order from small to large of community, carrier wave place.3rd step, according to the adjustment number of carriers preset, selects carrier wave to be adjusted.Represent with n the adjustment number of carriers preset, according to the sequence of second step, n carrier wave before selecting from the carrier wave after sequence, as carrier wave to be adjusted.On the basis of technique scheme, preferably, when selecting, if there is the carrier wave belonging to same cells, can only select the subcarrier in this community as carrier wave to be adjusted.
Step 307:RNC sends the community ID of community to be adjusted to NB.

Step 310:NB reports current candidate target frequency to RNC.
In this step, NB reports current candidate target frequency to RNC, and RNC obtains the current candidate target frequency that NB reports.Particularly, NB can report current candidate target frequency by private message to RNC.
Step 311:RNC according to target frequency selection strategy, select target frequency from current candidate target frequency.
In this step, target frequency selection strategy comprises: select frequency reusing degree to be less than the current candidate target frequency of the target frequency reusing degree thresholding of configuration as target frequency.Correspondingly, the detailed process of step 311 comprises: first, and RNC, according to the Neighboring Cell List of community to be adjusted, calculates the frequency reusing degree belonging to the current candidate target frequency of this community to be adjusted.Particularly, in RNC adjacent area, the access times of current candidate target frequency are divided by adjacent area intermediate-frequeney point sum, obtain the frequency reusing degree of current candidate target frequency.Then, RNC selects frequency reusing degree to be less than the current candidate target frequency of the target frequency reusing degree thresholding of configuration, as target frequency.In this step, further, the all right maximum reusing degree of goal-selling frequency of RNC, according to the frequency reusing degree of the current candidate target frequency that above-mentioned calculating obtains, deletes the frequency that current candidate target frequency intermediate-frequeney point reusing degree is greater than the maximum reusing degree of above-mentioned target frequency.
