Abstract
The invention discloses a neighbor cell maintenance method and a neighbor cell maintenance device. The neighbor cell maintenance process comprises the following steps: after acquiring candidate neighbor cells of a service cell (including configured neighbor cells in a configured neighbor cell list of the service cell and discovered unknown neighbor cells of the service cell), making statistical analysis of the switching performance of each neighbor cell; and selecting M neighbor cells of good switching performance as formal configured neighbor cells of the service cell according to the switching performance of each neighbor cell. According to the invention, after unknown neighbor cells are detected, whether or not to add the unknown neighbor cells is not judged immediately based on the current remaining space of the service cell. The switching performance of configured and to-be-configured neighbor cells is acquired first, and then, M neighbor cells of good switching performance are selected as formal configured neighbor cells of the service cell. Previously-configured neighbor cells of poorer performance than the selected M neighbor cells are deleted from the configured neighbor cell list. Thus, the added neighbor cells are neighbor cells of best switching performance.

Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment one:
Shown in Figure 1, the adjacent area maintaining method that the present embodiment provides comprises:
Step 101: obtain the candidate adjacent of Serving cell, this candidate adjacent comprises the unknown adjacent area of each Serving cell of configuring adjacent cell and discovery of Serving cell in configuring neighbor cell list, claims this kind of unknown adjacent area to be adjacent area to be configured herein;
Step 102: the performance of handoffs adding up each candidate adjacent;
Step 103: select the formal configuring adjacent cell as Serving cell that M performance of handoffs is good according to the performance of handoffs obtained from candidate adjacent; M is herein less than or equal to the maximum adjacent area number N that Serving cell is supported.
In above-mentioned steps 101, specifically automatically find to serve stingy unknown adjacent area by UE measurement in ANR process.After UE measurement in ANR process gets the ECGI (E-UTRANCellGlobalIdentifier) of adjacent area, just obtained and switched necessary neighboring BS information, system support service community is to the switching of adjacent area.Now first directly do not add neighbor cell configuration, but using the adjacent area to be configured of configuring adjacent cell and discovery all as the candidate adjacent of Serving cell, add up the performance of handoffs of the adjacent area to be configured (i.e. above-mentioned unknown adjacent area) of configuring adjacent cell and discovery, then resequence based on the adjacent area to be configured of performance of handoffs to configuring adjacent cell and discovery, then therefrom select the good adjacent area of M performance of handoffs, and then ensure that the adjacent area of adding is that in all adjacent areas, performance of handoffs is good.Specifically can according to the performance of handoffs of each adjacent area from getting well to the order differed from sort in configuring adjacent cell and adjacent area to be configured; Then select M the preceding adjacent area of sequence as the formal configuring adjacent cell of described Serving cell.
Preferably, when the number K sum (i.e. total number of candidate adjacent) of the number L of Serving cell configuring adjacent cell and the adjacent area to be configured of discovery is less than or equal to the maximum adjacent area number N supported Serving cell, i.e. L+K<=N, now show that Serving cell supports all adjacent areas to be configured directly all to add at present, therefore M now equals the number of configuring adjacent cell and the number sum of adjacent area to be configured, i.e. M=L+K;
When the number L of Serving cell configuring adjacent cell and the number K sum (i.e. total number of candidate adjacent) of adjacent area to be configured are greater than the maximum adjacent area number N supported Serving cell, i.e. L+K>N, show the maximum adjacent area number supported beyond Serving cell, M now equals N; Namely the adjacent area selecting N number of performance of handoffs best from all candidate adjacent is as formal allocating cell; For originally configured and performance of handoffs then delete from configuring neighbor cell list than the adjacent area of the N number of adjacent area difference selected.
In the present embodiment, the performance of handoffs of candidate adjacent by the handover success rate that user terminal is switched to the switching times of each candidate adjacent in the measurement period preset from Serving cell, user terminal is switched to each candidate adjacent in the measurement period preset from Serving cell and user terminal in the measurement period preset to the measurement of each candidate adjacent report number of times at least one characterize.Corresponding, in above-mentioned steps 102, the performance of handoffs adding up each candidate adjacent comprises: at the measurement period preset, (this measurement period is at least greater than the time once switched; In order to ensure the reliability of adding up, preferably be set to the integral multiple of a day) in, the handover success rate that counting user terminal is switched to the switching times of each candidate adjacent from Serving cell, user terminal is switched to each candidate adjacent from Serving cell and the measurement of user terminal to each candidate adjacent report at least one number of times.
Such as, only counting user terminal can be switched to the handover success rate of each configuring adjacent cell and each adjacent area to be configured from Serving cell, then according to handover success rate height, be sorted in each adjacent area;
Again such as: only counting user terminal can be switched to the switching times of each configuring adjacent cell and each adjacent area to be configured from Serving cell, then according to switching times height, be sorted in each adjacent area;
Such as, counting user terminal can be switched to switching times and the handover success rate of each configuring adjacent cell and each adjacent area to be configured from Serving cell, then first according to handover success rate height, sorted in each adjacent area, for the adjacent area that handover success rate is identical, then resequence according to the height of switching times; Probable rear elder generation sorts to each adjacent area according to switching times height, for the adjacent area that switching times is identical, then resequences according to the height of handover success rate.
In order to ensure statistical accuracy and reliability as far as possible in the present embodiment, the handover success rate that preferred counting user terminal to be switched to the switching times of each candidate adjacent in the measurement period preset from Serving cell, user terminal is switched to each candidate adjacent in the measurement period preset from Serving cell and user terminal report number of times to the measurement of each candidate adjacent in the measurement period preset.Now to the order differed from, sequence is carried out to described each candidate adjacent according to performance of handoffs comprise from getting well:

Whether be greater than predetermined threshold value according to the switching times of each candidate adjacent and each candidate adjacent is divided into the first queue (for being greater than each candidate adjacent of predetermined threshold value in the present embodiment, the probability that Serving cell switches to these candidate adjacent is greater than each candidate adjacent in the second queue, therefore to be come each candidate adjacent in the first queue in the second queue before each candidate adjacent in the present embodiment) and the second queue (for being less than or equal to each candidate adjacent of predetermined threshold value in the present embodiment); Then neutralize each candidate adjacent in the second queue to the first queue respectively to sort according to preset rules and obtain the first collating sequence and the second collating sequence respectively, after the candidate adjacent in the second collating sequence being added successively to last candidate adjacent in the first collating sequence.In the present embodiment, predetermined threshold value specifically can the factor such as network environment residing for historical statistics switching times and each Serving cell be arranged.
Preset rules in the present embodiment is: first sort according to handover success rate order from high to low, identical for handover success rate, minor sort is again carried out again according to switching times order from high to low, for handover success rate and switching times all identical, then according to measurement report number of times order from high to low to carry out minor sort again.Concrete: each adjacent area switching times being greater than to the first queue of predetermined threshold value, its sequencer procedure is: first sort to each adjacent area according to handover success rate order from high to low, for the adjacent area that handover success rate is identical, minor sort is again carried out again according to switching times order from high to low, for handover success rate and switching times all identical, then according to measurement report number of times order from high to low to carry out minor sort again.For each candidate adjacent in the second queue, its sequencer procedure and said process similar, do not repeat them here.
After the above steps, can measurement period be restarted, perform next round statistics.The adjacent area that can always keep configured like this is that in the abutting subdistrict of Serving cell, performance of handoffs is best.
In the present embodiment, when the number K sum (i.e. total number of candidate adjacent) of the number L of Serving cell configuring adjacent cell and the adjacent area to be configured of discovery is less than or equal to the maximum adjacent area number N supported Serving cell, i.e. L+K<=N, now shows that Serving cell supports all adjacent areas to be configured directly all to add at present.The each performance of handoffs of configuring adjacent cell and the performance of handoffs of adjacent area to be configured in Serving cell configuring neighbor cell list can not be added up, but directly using configuring adjacent cell and adjacent area to be configured all as the formal configuring adjacent cell of Serving cell.Therefore, in the present embodiment, between above-mentioned steps 101 and step 102, also comprise:
Judge whether configuring adjacent cell number L and adjacent area to be configured number K sum (i.e. total number of candidate adjacent) are less than or equal to the maximum adjacent area number N supported Serving cell, in this way, then directly just configuring adjacent cell and adjacent area to be configured all as the formal configuring adjacent cell of Serving cell; Otherwise, carry out the statistics of the performance of handoffs of configuring adjacent cell and adjacent area to be configured.
After the above steps, during new discovery the unknown adjacent area, can measurement period be restarted, perform next round statistics.The adjacent area that can always keep configured like this is that in the abutting subdistrict of Serving cell, performance of handoffs is best.

Such as, can be switched to the handover success rate of each configuring adjacent cell and each adjacent area to be configured from Serving cell by means of only switching statistics submodule counting user terminal, then sorting sub-module sorts to each adjacent area according to handover success rate height;
Again such as: the switching times that can be switched to each configuring adjacent cell and each adjacent area to be configured by means of only switching statistics submodule counting user terminal from Serving cell, then sorting sub-module sorts to each adjacent area according to switching times height;
Such as, switching times and the handover success rate of each configuring adjacent cell and each adjacent area to be configured can be switched to from Serving cell by switching statistics submodule counting user terminal, then sorting sub-module first sorts to each adjacent area according to handover success rate height, for the adjacent area that handover success rate is identical, then resequence according to the height of switching times; Probable rear elder generation sorts to each adjacent area according to switching times height, for the adjacent area that switching times is identical, then resequences according to the height of handover success rate.
In order to ensure statistical accuracy and reliability as far as possible in the present embodiment, preferably by switching statistics submodule user terminal and be switched to from Serving cell in the measurement period preset the switching times of each candidate adjacent, user terminal is switched to each candidate adjacent in the measurement period preset handover success rate from Serving cell and report number of times to add up submodule counting user terminal to report number of times to the measurement of each candidate adjacent in the measurement period preset by measuring.Now sorting sub-module carries out sequence to the order differed to described configuring adjacent cell and adjacent area to be configured according to the performance of handoffs of each adjacent area comprise from getting well:
