Background technique

Neighbor optimization is an important factor affecting network performance. Therefore, how to implement a reasonable neighbor optimization method becomes an important task for optimizing the network.

At present, there are many neighboring optimization methods for the UMTS (Universal Mobile Telecommunications System) network. The simplest is to calculate the distance and coverage direction between the two cells under the base station according to the geographical location of the cell, thereby obtaining the priority configured as the neighboring cell. However, this method does not take into account factors such as actual geographical location and obstacles. Another more advanced solution is to obtain a comprehensive score ranking priority by collecting the actual switching data and setting the switching data and distance to a specific weight. The disadvantage of this scheme is that the weight of the set permissions largely affects the results of the neighborhood optimization, and it is difficult for the user to set this value, which is difficult to operate. Moreover, these neighboring area optimization methods deviate from the actual scene, and there is no comprehensive consideration of whether adding or deleting neighboring areas will cause problems such as single allocation and scrambling code multiplexing. Therefore, the difficulty in setting the authority weight value in the existing neighborhood optimization method and the deviation from the actual site are an urgent problem to be solved.

detailed description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to The invention is defined.

The present invention provides a neighboring area optimization method. Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a neighboring area optimization method according to the present invention. In the first embodiment, the neighboring area optimization method includes the following steps:

Step S100: Collect data of soft handover and virtual handover.

The terminal continuously reports the measurement report to the RNC (Radio Network Controller), where the terminal may be referred to as a UE (User Equipment), and may also be called a mobile terminal (Mobile Terminal), a mobile user equipment, etc.; The cell in the monitoring set of the neighboring cell can be measured and reported, and the cell in the detection set where the neighboring cell relationship is not configured can be measured and reported. In this embodiment, the terminal collects the virtual handover data that occurs in the handover and detection set that actually occurs within a few days from the foreground. The soft handover refers to channel switching between cells when the carrier frequencies of the pilot channels are the same. The virtual handover refers to a false handover, which causes waste of resources.

Step S200: Acquire preliminary results of neighborhood optimization according to the collected soft handover and virtual handover data and a preset handover threshold.

The terminal obtains the preliminary result of the neighborhood optimization according to the collected soft handover and virtual handover data and the preset handover threshold. The preset switching threshold may be the number of handovers or the proportion of handover. The preliminary result of the neighboring area optimization may be correspondingly adding or deleting the neighbor relationship of the cell pair, or filtering the data of the neighboring area, etc. For example, if the terminal detects that the number of virtual handovers of the cell pair is less than a preset handover threshold and the ratio of the virtual handover is less than a preset handover ratio threshold, determining that the cell pair is an invalid neighboring pair, The virtual switched data is filtered out. The two cells form a cell pair. For example, the primary cell and the neighboring cell may form a cell pair.

Step S300: Adjust the preliminary result of the neighboring area optimization according to the preset neighboring area parameter.

The terminal adjusts the preliminary result of the obtained neighboring area optimization according to the preset neighboring area parameter, where the preset neighboring area parameter may be a red and black list, a neighboring area mutual allocation, a neighboring number threshold, and a disturbance. A combination of one or more of the code multiplexing, wherein the priority order of the neighboring cell parameters is preceded by a red and black list, for example, if the AB cell is not added as a neighbor relationship in the preliminary result of the neighboring area optimization, but When there is an AB cell in the red list in the red blacklist, the AB cell is added as a neighbor relationship.

The neighboring area optimization method provided in this embodiment solves the problem that the authority specific value is difficult to set and deviates from the actual scene, and the optimization efficiency of the neighboring area is improved, and the accuracy is high.

As shown in FIG. 2, FIG. 2 is a schematic diagram of a refinement process of step S200 in FIG. 1, and the step S200 includes:

Step S210: If it is detected that the number of virtual handovers of the cell pair is less than a preset handover threshold and the ratio of the virtual handover is less than a preset handover ratio threshold, determine that the cell pair is an invalid neighbor pair, and the virtual The switched data is filtered out.

If the number of times that the virtual handover of the cell pair is less than the preset handover threshold and the ratio of the virtual handover is less than the preset handover ratio threshold, the terminal determines that the cell pair is an invalid neighbor pair, and the virtual handover The data is filtered out. The ratio of the virtual handover is the sum of the virtual handover times of the cell pair, the sum of the virtual handover times and the soft handover times of the primary cell as a denominator, the calculated ratio, the preset handover threshold, and the preset handover threshold. It can be preset according to the actual needs of the user, or can be appropriately adjusted in actual operation. For example, the switching threshold can be set to 50 times and the switching ratio threshold is set to 2%, then if the virtual switching of the cell pair is detected, If the number of times is less than 50 and the ratio of the virtual handover is less than 2%, it is confirmed that the cell pair is an invalid cell pair, and the data of the virtual handover of the cell is filtered out.

Step S220: If it is detected that the number of virtual handovers of the cell pair is greater than or equal to a preset handover threshold, and the ratio of the virtual handover is greater than or equal to a preset handover ratio threshold, and the cell pair is not configured with a neighbor relationship, the corresponding addition is performed. The cell pair is a neighbor relationship.

The admission conditions for the neighbor cell relationship set by the terminal in advance are as follows:

1. The number of virtual handovers of the cell pair is greater than or equal to a preset handover threshold;

2. The ratio of the virtual handover is greater than or equal to the preset handover ratio threshold;

3. The cell pair is not configured with a neighbor relationship.

The ratio of the virtual handover is the sum of the virtual handover times of the cell pair, the sum of the virtual handover times and the soft handover times of the primary cell as a denominator, the calculated ratio, the preset handover threshold, and the preset handover threshold. It can be preset according to the actual needs of the user. If the above three conditions are simultaneously established, the terminal adds the cell pair as a neighbor relationship.

As shown in Table 1, after the cell A filters the virtual handover data according to step S100 and step S200, it is calculated that the sum of the soft handover and the virtual handover times of the same frequency in the cell A is 7641, and the utilization rate of the cell A is 89%; All the information of the same-frequency neighboring cell relationship with the cell A or the intra-frequency handover cell is listed.

Table 1

It should be noted that the cell IDs of the primary cell and the neighboring cells (N1 to N16) are directly recorded in the soft handover data, but the virtual handover data records only the number of times the primary cell ID and the neighboring area scrambling code are switched, therefore, For virtual handover, it is also necessary to find the cell M whose scrambling code is closest to the cell A.

Assume that the virtual handover set by the terminal increases the threshold of the neighbor relationship as the neighbor relationship: the handover threshold S=1%, and the handover threshold C=50, then the last two virtual cells in the above table correspond to the initial neighbor optimization. The recommendations are as shown in Table 2:

Table 2

Step S230: If it is detected that the number of virtual handovers of the cell pair is less than a preset handover threshold, the ratio of the virtual handover is less than a preset handover ratio threshold, the utilization of the cell pair is greater than or equal to a preset utilization threshold, and the cell When the neighbor relationship is configured, the neighbor relationship of the cell pair is deleted.

The admission conditions for the neighbor relationship of the deleted cell pair preset by the terminal are as follows:

1. The number of virtual handovers of the cell pair is less than a preset handover threshold;

Second, the ratio of virtual switching is less than a preset switching ratio threshold;

3. The utilization rate of the cell pair is greater than or equal to the preset utilization threshold;

4. The cell pair has been configured as a neighbor relationship.

The ratio of the virtual handover is the sum of the virtual handover times of the cell pair, the sum of the virtual handover times and the soft handover times of the primary cell as a denominator, the calculated ratio, the preset handover threshold, and the preset handover threshold. It can be preset according to the actual needs of the user. If the above four conditions are simultaneously established, the terminal deletes the neighbor relationship of the cell pair.

As shown in Table 3, assuming that the handover threshold set by the terminal is N=200, the handover ratio threshold is 0.2%, and the utilization threshold of the primary neighboring cell is 80%, the neighbor relationship that satisfies the three thresholds needs to be deleted. Therefore, The preliminary optimization suggestions are updated as follows:

table 3

It should be noted that the above steps S210, S220 and S230 do not have a strict execution sequence.

Referring to FIG. 3 again, FIG. 3 is a schematic flowchart of the refinement of the first embodiment of step S300 in FIG. 1, and the step S300 includes:

Step S310: Configure a neighbor relationship for the cell pair according to the obtained preliminary result of the neighboring cell optimization and the preset red and black list.

Step S320: If the cell pair is in the preset redlist and is not added to the neighbor relationship, the cell pair is added to be a neighbor relationship.

Step S330: If the cell is in a preset redlist and the neighbor relationship of the cell pair has been deleted, the neighbor relationship of the cell pair is newly added.

The terminal further optimizes the neighboring cell according to the obtained preliminary result of the neighboring cell optimization and the preset red and black list, for example, if the AB cell pair is preset in the red list table and the AB cell is not added in the previous preliminary neighboring area optimization result For the neighbor relationship, add the AB cell pair as a neighbor. If the A-B cell pair is set in the redlist table and the neighbor relationship of the A-B cell pair is deleted, the neighbor relationship of the A-B cell pair is re-added, and the purpose is to ensure that the A-B cell pair is configured as a neighbor relationship. Similarly, if the AB cell pair is preset in the blacklist table and the previous optimization result has added the AC cell pair to the neighbor relationship, the neighbor relationship of the AC cell pair is deleted; if the AB cell pair is preset in the blacklist table If the previous optimization result does not add the AC cell pair to the neighbor relationship, then the AC cell pair still has no neighbor relationship.

On the basis of the optimization example in Table 3 above, assuming that there is an A-M3 record in the preset red list and an A-N5 record in the black list, the neighboring area optimization result is updated as shown in Table 4:

Table 4

Referring to FIG. 4, FIG. 4 is a schematic diagram of a refinement process of the second embodiment of step S300 in FIG. 1, and the step S300 includes:

Step S340: Perform mutual matching processing on the neighboring relationship of the added cell pair according to the preliminary result of the obtained neighboring cell optimization.

Step S350: If there is no reverse neighboring cell pair in the added cell pair, add the reverse neighboring cell pair.

Step S360: If the reverse cell pair is in the preset redlist and the neighbor relationship of the reverse cell pair has been deleted, the neighbor relationship of the reverse cell pair is re-added.

The terminal performs mutual matching processing on the neighboring cell relationship of the added cell pair according to the obtained preliminary result of the neighboring cell optimization, and the processing principle of the neighboring cell mutual matching is: adding the neighboring cell without violating the limitation of the red and black list a neighboring cell pair of the relationship, if there is no reverse neighboring cell, adding a reverse neighboring cell pair; if the reverse cell pair is in a preset redlist and the neighboring cell relationship of the reverse cell pair has been deleted And then re-add the neighbor relationship of the reverse cell pair.

Continuing with the example in Table 4, if the optimization result does not exist in the M1-A neighbor relationship or if there is no M1-A in the neighboring cell relationship, then the A-M1 is configured as a neighbor and becomes a single match. Therefore, it is necessary to increase the M1. -A's neighborhood relationship. Assume that there is an N5-A neighboring pair in the optimization result. According to the principle of mutual matching, A-N5 in Table 4 needs to be added as a neighboring relationship. However, since A-N5 exists in the blacklist, the blacklist takes precedence, so A The neighbor relationship of -N5 still needs to be deleted. The optimization results are shown in Table 5:

table 5

As shown in FIG. 5, FIG. 5 is a schematic flowchart of a second embodiment of a neighboring cell optimization method according to the present invention. On the basis of the first embodiment, the neighboring cell optimization method provided by the second embodiment includes:

Step S300A: Limiting the number of neighboring cells. If the number of neighboring cells of the cell pair is not within a preset threshold of the number of neighboring cells, the number of neighboring cells is adjusted within a range of the number of neighboring cells.

The terminal presets the number of neighboring cells to limit the number of neighboring cells. If the number of neighboring cells in the cell pair is not within the threshold of the preset neighboring cell number, the number of neighboring cells is adjusted in the neighboring cell. Within the range of a few thresholds.

First, the number of neighboring areas (the number of existing neighboring areas + the number of adjacent neighboring areas - the number of deleted neighboring areas) - When the maximum value of the maximum neighboring cell threshold is N>0, the neighboring cell relationship of the added cell pair needs to be partially deleted.

a. If the neighbor relationship of the added cell pair exists in the red list, the added neighbor relationship of the cell pair is preferentially reserved.

b. After considering the limitation of the red list, the neighboring relationship of the remaining added cell pairs is arranged in descending order according to the virtual cut ratio of the neighbor relationship;

c. If the virtual cut ratios are equal, the second order is sorted in ascending order, and the neighbor relationship of the N pairs of cell pairs at the last position after the added sort is deleted.

2. When the number of neighboring cells (the number of existing neighboring cells + the number of neighboring cells added - the number of deleted neighboring cells) - the minimum value of the neighboring cell number threshold M < 0, it is necessary to partially add neighboring cells Deleted neighbor relationship.

a. If the deleted neighbor relationship exists in the blacklist, the neighbor relationship of the cell pair is preferentially deleted.

b. After considering the limitation of the blacklist, the neighboring relationship of the remaining deleted cell pairs is arranged in ascending order according to the soft-cut ratio of the neighboring area relationship.

c. When the soft cut ratios are equal, the distances are descended in descending order, and the neighbor relationship of the M cell pairs located at the last after sorting is newly added.

Assume that the maximum value of the neighboring number threshold is M=31, and the minimum value of the neighboring number threshold is N=15. Under the limitation of these two thresholds, because the number of neighboring cells is not enough, according to the above rule of restricting the number of neighboring cells, the neighboring zone relationship of A-N3 and A-N4 in the preceding neighboring zone optimization suggestion is changed from deleted to not deleted. Although A-N5 has a larger switching ratio, A-N5 still needs to be deleted in the blacklist. Further optimization results are shown in Table 6:

Table 6

As shown in FIG. 6 , FIG. 6 is a schematic flowchart of a third embodiment of a neighboring cell optimization method according to the present invention. On the basis of the first embodiment, the neighboring cell optimization method provided by the third embodiment includes:

Step S300B: If the added cell pair has scrambling code multiplexing, delete the neighbor relationship of the cell pair.

The terminal further checks the scrambling code multiplexing situation in the neighbor relationship between the addition and deletion. If the neighboring cell relationship of the added cell pair has scrambling code multiplexing, the neighboring cell relationship of the cell pair needs to be deleted, so as to achieve the purpose of eliminating the scrambling code multiplexing path. In this embodiment, an example of checking the two-layer scrambling code multiplexing is taken as an example.

Assume that cell A is configured with B as the neighboring cell and cell B is configured with C as the neighboring cell. Then cell C is the second-layer neighboring cell relationship of cell A. As shown in Table 7, A-C has the following four paths: A-->B indicates that A is configured with B as the neighboring cell, and A<--B indicates that B is configured with A as the neighboring cell. Only the first three are valid paths. That is to say, in the path of the first three cases, when A and C are in the same frequency and the same scrambling code, there will be interference between A and C, that is, A and C have scrambling code multiplexing.

邻区链Neighbor chain	A--BA--B	B--CB--C	属性Attributes
邻区链Neighbor chain	A--BA--B	B--CB--C	属性Attributes	11	<--<--	<--<--	有效组合Effective combination

44	-->-->	<--<--	无效组合Invalid combination	33	-->-->	-->-->	有效组合Effective combination

Table 7

Taking neighboring chain 1 as an example, when A and C have scrambling code multiplexing, and B<--C is the neighboring pair added in the neighboring area optimization proposal, then B<-- C This added neighborhood relationship should be removed. Check all the networks and find all the links that have Layer 2 scrambling code multiplexing. If these links contain the recommended neighboring areas, you need to delete the neighbors that have been added to eliminate the scrambling code. .

As shown in FIG. 7, FIG. 7 is a schematic diagram of a function module according to a first embodiment of the present invention. The terminal provided in this embodiment includes:

The collecting module 10 is configured to collect data of the soft switching and the virtual switching;

The obtaining module 20 is configured to obtain a preliminary result of the neighboring area optimization according to the collected data of the soft switching and the virtual switching and the preset switching threshold;

The adjusting module 30 is configured to adjust the preliminary result of the neighboring area optimization according to the preset neighboring area parameter.

The collection module 10 of the terminal continuously reports the measurement report to the RNC. The terminal may be referred to as a UE, and may also be referred to as a mobile terminal or a mobile user equipment. The terminal may not only perform measurement reports on the cells in the monitoring set of the neighboring area, but also The cells in the detection set in which the neighbor relationship is not configured may be measured and reported. In this embodiment, the terminal collects the virtual handover data that occurs in the handover and detection set that actually occurs within a few days from the foreground. The soft handover refers to channel switching between cells when the carrier frequencies of the pilot channels are the same. The virtual handover refers to a false handover, which causes waste of resources.

The acquiring module 20 of the terminal is configured according to the collected soft switching and virtual switching data and a preset cut. Change the threshold to obtain preliminary results of neighborhood optimization. The preset switching threshold may be the number of handovers or the proportion of handover. The preliminary result of the neighboring area optimization may be correspondingly adding or deleting the neighbor relationship of the cell pair, or filtering the data of the neighboring area, etc. For example, if the terminal detects that the number of virtual handovers of the cell pair is less than a preset handover threshold and the ratio of the virtual handover is less than a preset handover ratio threshold, determining that the cell pair is an invalid neighboring pair, The virtual switched data is filtered out.

The adjustment module 30 of the terminal adjusts the preliminary result of the obtained neighboring area optimization according to the preset neighboring area parameter, where the preset neighboring area parameter may be a red and black list, a neighboring area mutual allocation, a neighboring number threshold, and A combination of one or more of the scrambling code multiplexing, wherein the priority order of the neighboring cell parameters is preceded by a red and black list, for example, if the AB cell is not added as a neighbor relationship in the preliminary result of the neighboring cell optimization, When there is an AB cell in the red list in the red and black list, the AB cell is added as a neighbor relationship.

The terminal provided in this embodiment solves the problem that the priority value of the authority is difficult to set and deviates from the actual site, and the optimization efficiency of the neighboring area is improved, and the accuracy is high.

As shown in FIG. 8, FIG. 8 is a schematic diagram of functional modules of the acquiring module in FIG. 7, and the obtaining module 20 includes:

The filtering unit 21 is configured to: if it is detected that the number of virtual handovers of the cell pair is less than a preset handover threshold and the ratio of the virtual handover is less than a preset handover ratio threshold, determine that the cell pair is an invalid neighboring zone pair, Filtering the virtual switched data;

The adding unit 22 is configured to: if it is detected that the number of virtual handovers of the cell pair is greater than or equal to a preset handover threshold, the ratio of the virtual handover is greater than or equal to a preset handover ratio threshold, and the cell pair is not configured with a neighbor relationship relationship, And correspondingly adding the cell pair to a neighbor relationship;

The deleting unit 23 is configured to: if it is detected that the number of virtual handovers of the cell pair is less than a preset handover threshold, the ratio of the virtual handover is less than a preset handover ratio threshold, and the utilization of the cell pair is greater than or equal to a preset utilization threshold When the cell pair has configured the neighbor relationship, the corresponding deletion is performed. The neighbor relationship of the cell pair.

If the number of times that the virtual handover of the cell pair is less than the preset handover threshold and the ratio of the virtual handover is less than the preset handover ratio threshold, the filtering unit 21 of the terminal determines that the cell pair is invalid. The virtual switched data is filtered out. The ratio of the virtual handover is the sum of the virtual handover times of the cell pair, the sum of the virtual handover times and the soft handover times of the primary cell as a denominator, the calculated ratio, the preset handover threshold, and the preset handover threshold. It can be preset according to the actual needs of the user, or it can be adjusted in the actual operation. For example, the switching threshold can be set to 50 times and the switching ratio threshold is set to 2%, then if the virtual switching of the cell pair is detected, If the number of times is less than 50 and the ratio of virtual handover is less than 2%, it is confirmed that the cell pair is an invalid cell pair, and the data of the virtual handover of the cell is filtered out.

The admission conditions for the added cell pair set by the adding unit 22 of the terminal to be the neighbor relationship are as follows:

3. The cell pair is not configured with a neighbor relationship.

It should be noted that the cell IDs of the primary cell and the neighboring cells (N1 to N16) are directly recorded in the soft handover data, but only the primary cell ID and the neighboring zone are recorded in the virtual handover data record. The number of times the code is switched, therefore, for the virtual handover, it is also necessary to find the cell M whose scrambling code is closest to the cell A.

Assume that the virtual handover set by the terminal increases the threshold of the neighbor relationship as the neighbor relationship: the handover threshold S=1%, and the handover threshold C=50, then the last two virtual cells in the above table correspond to the initial neighbor optimization. The recommendations are shown in Table 2.

The admission conditions of the neighboring cell relationship of the deleted cell pair set by the deleting unit 23 of the terminal are as follows:

4. The cell pair has been configured as a neighbor relationship.

As shown in Table 3, assuming that the handover threshold set by the terminal is N=200, the handover ratio threshold is 0.2%, and the utilization threshold of the primary neighboring cell is 80%, the neighbor relationship that satisfies the three thresholds needs to be deleted. Therefore, The preliminary optimization recommendations were updated to be shown in Table 3.

As shown in FIG. 9, FIG. 9 is a schematic diagram of a functional module of the first embodiment of the adjustment module of FIG. 7. The adjustment module 30 provided by the first embodiment includes:

The configuration unit 31 is configured to configure a neighbor relationship for the cell pair according to the obtained preliminary result of the neighboring cell optimization and the preset red and black list;

The redlisting unit 32 is configured to add the cell pair as a neighbor relationship if the cell pair is in a preset redlist and is not added to the neighbor relationship; if the cell is in a preset red list If the neighbor relationship of the cell pair has been deleted, the neighbor relationship of the cell pair is newly added.

The configuration unit 31 of the terminal further optimizes the neighboring cell according to the obtained preliminary result of the neighboring cell optimization and the preset red and black list. For example, the redlisting unit 32 of the terminal is preset in the redlist table and is in front of the If the AB cell pair is not added to the neighboring cell relationship, the AB cell pair is added as the neighbor relationship; if the AB cell pair is set in the red list and the neighbor relationship of the AB cell pair is deleted, the R zone is re-added. The neighboring relationship of the AB cell pair is intended to ensure that the AB cell pair is necessarily assigned a neighbor relationship. Similarly, if the AB cell pair is preset in the blacklist table and the previous optimization result has added the AC cell pair as the neighbor relationship, then the neighbor relationship of the AC cell pair is deleted; if the AB cell pair is preset in the blacklist table If the previous optimization result does not add the AC cell pair to the neighbor relationship, then the AC cell pair still has no neighbor relationship.

Based on the optimization example of Table 3 above, assuming that there is an A-M3 record in the preset red list and a record of A-N5 in the black list, the neighboring area optimization result is updated as shown in Table 4.

As shown in FIG. 10, FIG. 10 is a schematic diagram of a functional module of a second embodiment of the adjustment module of FIG. 7. The entire module 30 provided by the second embodiment includes:

The interworking unit 33 is configured to perform interworking processing on the neighbor relationship of the added cell pair according to the preliminary result of the obtained neighboring cell optimization;

The reverse neighboring cell pair adding unit 34 is configured to add the reverse neighboring cell pair if the added cell pair does not have a reverse neighboring cell pair;

The reverse neighboring cell re-addition unit 35 is configured to re-add the reverse cell pair if the reverse cell pair is in a preset redlist and the neighbor relationship of the reverse cell pair has been deleted. Neighborhood relationship.

The inter-matching unit 33 of the terminal performs mutual matching processing on the neighboring cell relationship of the added cell pair according to the preliminary result of the obtained neighboring cell optimization, and the processing principle of the neighboring cell mutual matching is: the premise of not violating the red-black list restriction Next, the neighboring cell pair of the neighboring cell relationship is added; if the reverse neighboring cell pair adding unit 34 detects that there is no reverse neighboring cell, the reverse neighboring cell pair is added; if the reverse neighboring cell counterweighting unit 35 detects the The reverse cell pair is in the preset red list and the neighbor relationship of the reverse cell pair has been deleted. In addition, the neighbor relationship of the reverse cell pair is re-added.

Continuing with the example in Table 4, if the optimization result does not exist in the M1-A neighbor relationship or if there is no M1-A in the neighboring cell relationship, then the A-M1 is configured as a neighbor and becomes a single match. Therefore, it is necessary to increase the M1. -A's neighborhood relationship. Assume that there is an N5-A neighboring pair in the optimization result. According to the principle of mutual matching, A-N5 in Table 4 needs to be added as a neighboring relationship. However, since A-N5 exists in the blacklist, the blacklist takes precedence, so A The neighbor relationship of -N5 still needs to be deleted. The optimization results are shown in Table 5.

Referring to FIG. 7, in the adjustment module 30, the adjustment module 30 is further configured to limit the number of neighboring cells, if the number of neighboring cells in the cell pair is not in the range of the preset neighboring number threshold. At the same time, the number of neighboring cells is adjusted within the range of the number of neighboring cells.

The adjustment module 30 of the terminal presets the number of neighboring cells to limit the number of neighboring cells. If the number of neighboring cells in the cell pair is not within the preset threshold of the neighboring cell, the number of neighboring cells is adjusted. Within the range of the threshold of the neighboring area.

1. When the number of neighboring cells (the number of existing neighboring cells + the number of neighboring cells added - the number of deleted neighboring cells) - the maximum value of the maximum number of neighboring cells is N>0, then partial deletion has been added. The neighbor relationship of the cell pair.

Assume that the maximum value of the neighboring number threshold is M=31, and the minimum value of the neighboring number threshold is N=15. Under the limitation of these two thresholds, because the number of neighboring cells is not enough, according to the above rule of restricting the number of neighboring cells, the neighboring zone relationship of A-N3 and A-N4 in the preceding neighboring zone optimization suggestion is changed from deleted to not deleted. Although A-N5 has a larger switching ratio, A-N5 still needs to be deleted in the blacklist. Further optimization results are shown in Table 6.

Referring to FIG. 7 , in the adjustment module provided in this embodiment, the adjustment module 30 is further configured to delete the neighbor relationship of the cell pair if the added cell pair has scrambling code multiplexing.

The adjustment module 30 of the terminal further checks the scrambling code multiplexing situation on the neighbor relationship of the addition and deletion. If the neighboring cell relationship of the added cell pair has scrambling code multiplexing, the neighboring cell relationship of the cell pair needs to be deleted, so as to achieve the purpose of eliminating the scrambling code multiplexing path. In this embodiment, an example of checking the two-layer scrambling code multiplexing is taken as an example.
