Description

Method and device for identifying missing neighbor cell

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for identifying a missed neighbor cell.

Background

In order to ensure the communication quality of the mobile station, the neighboring cell configured for the serving cell needs to be accurate and complete. However, due to the continuous change of the mobile communication network, for example, due to the existence of network construction behaviors such as relocation, capacity expansion, frequency change and the like, the neighboring cells of each service cell are dynamically changed, which may result in the continuous change of the mobile communication network, and due to the existence of city construction behaviors such as building a new building, transforming an original building and the like, which may also result in the continuous change of the mobile communication network, thereby affecting the configuration of the neighboring cells of the service cell, so that the service cell may have the neighboring cells which are missed in configuration, that is, the neighboring cells which are missed in configuration. The existence of the missed neighbor cell will cause the mobile station not to be switched from the current serving cell to the primary coverage cell, thereby affecting the communication quality of the mobile station. For example, in the case where the second serving cell is a neighboring cell of the first serving cell and the second serving cell is not configured as a neighboring cell of the first serving cell, when the mobile station moves from the first serving cell to the second serving cell, the mobile station will not be able to switch from the first serving cell to the second serving cell, i.e., the primary coverage cell, and thus the communication quality of the mobile station may be affected. Therefore, in order to ensure the communication quality of the mobile station, the missed neighbor cell of the serving cell needs to be identified.

The method for identifying the missing neighbor cell provided in the related art generally includes determining whether the serving cell has the missing neighbor cell by adding a test neighbor cell to the serving cell. On one hand, because the number of the adjacent cells of the service cell is limited in the mobile communication network, when the number of the adjacent cells of the service cell reaches the limited number, the test adjacent cells cannot be added to the service cell, so that the missing adjacent cells of the service cell cannot be identified by the method; on the other hand, the method needs a large amount of manual operation, so that the method has the problems that the missing adjacent cell cannot be identified automatically and accurately in real time, the missing adjacent cell needs to be identified by a large amount of manpower, and the like, and therefore the identification efficiency and the accuracy of the identification result are reduced.

Detailed Description

In the embodiment of the invention, a base station acquires a measurement report reported by a mobile station of a service cell; the measurement report includes information related to a neighboring cell of the serving cell; the base station counts out the adjacent cells with the occurrence frequency exceeding a preset threshold value according to the currently acquired relevant information of the adjacent cells, and takes the adjacent cells with the occurrence frequency exceeding the preset threshold value as the adjacent cells to be judged; and the base station confirms the neighbor cell to be judged which does not exist in the neighbor cell list of the service cell as the missing neighbor cell of the service cell.

The present invention will be described in further detail with reference to the following drawings and specific examples.

Fig. 1 is a schematic flowchart of a method for identifying a missed neighbor cell according to an embodiment of the present invention, as shown in fig. 1, the method includes:

step 101: acquiring a measurement report reported by a mobile station of a serving cell; the measurement report includes information about the neighbor of the serving cell.

Specifically, the step may be that the base station obtains a measurement report reported by the mobile station of the serving cell; the measurement report includes information about the neighbor of the serving cell.

Specifically, the implementation procedure of this step may include that the mobile station selects a cell as a serving cell; a Broadcast Control Channel Allocation (BA) list of a Base Station, where the BA list includes Broadcast Control Channel (BCCH) frequency points and Base Station Identity Codes (BSICs) of each neighboring cell of a serving cell; the mobile station of the service cell receives the BA list and measures the level value of BCCH frequency point of each adjacent cell in the BA list; the mobile station of the service cell reports a measurement report to the base station, wherein the measurement report comprises level values, BCCH and BSIC of adjacent cells with the strongest level values; the base station receives the measurement report. Therefore, the base station can acquire the relevant information of the adjacent cell of the service cell.

It should be noted that the relevant information of the neighboring cell may include information such as BCCH and BSIC of the neighboring cell.

The base station may be a Global System for mobile communication (GSM) base station or a Code Division Multiple Access (CDMA) base station of a CDMA mobile communication System.

Step 102: and counting the adjacent cells with the occurrence frequency exceeding a preset threshold value according to the currently acquired related information of the adjacent cells, and taking the adjacent cells with the occurrence frequency exceeding the preset threshold value as the adjacent cells to be judged.

Specifically, in this step, the base station may count up the neighboring cells whose occurrence frequency exceeds the preset threshold according to the currently acquired relevant information of the neighboring cells, and use the neighboring cells whose occurrence frequency exceeds the preset threshold as the neighboring cells to be determined.

Specifically, the implementation process of this step may include that the currently acquired relevant information of the neighboring cell includes BCCH and BSIC of the neighboring cell; the base station takes BCCH and BSIC of the adjacent region as identification information of the adjacent region; the base station calculates the occurrence frequency value of each adjacent cell according to the currently acquired identification information of each adjacent cell; and the base station takes the adjacent cell with the frequency value exceeding the preset threshold value as the adjacent cell to be judged.

It should be noted that the preset threshold may be set according to actual requirements. For example, the mobile station of the serving cell reports a measurement report to the base station every 0.48 seconds, the base station obtains the measurement report of the mobile station of the serving cell every 0.48 seconds, the base station receives the measurement report each time and includes 6 neighboring cells with the strongest level values, and when it is expected that the base station determines whether the neighboring cell with the frequency value exceeding the empirical value, e.g., 15 or 5, in the currently obtained measurement report is the missing neighboring cell of the serving cell, the preset threshold value may be set to the empirical value, e.g., 15 or 5. The experience value may be set by a mobile network manager according to the mobile network management experience.

Step 103: and confirming the neighbor cell to be judged which does not exist in the neighbor cell list of the service cell as the missing neighbor cell of the service cell.

Specifically, since the neighbor cell configured for the serving cell is usually stored in the neighbor cell list of the serving cell, when there is no neighbor cell to be determined in the neighbor cell list of the serving cell, the base station determines that the neighbor cell to be determined is not configured as the neighbor cell of the serving cell, that is, the neighbor cell to be determined is determined to be the missing neighbor cell of the serving cell. Therefore, the missing neighbor cell of the serving cell can be identified automatically and accurately in real time, a large amount of manpower is not required to be consumed in the whole process, and the identification efficiency and the accuracy of the identification result are improved.

Specifically, the step may include the base station determining whether the neighbor cell list of the serving cell has identification information of a neighbor cell to be determined; and when the identification information of the neighbor cell to be judged does not exist in the neighbor cell list of the service cell, the base station confirms the neighbor cell to be judged as the missing neighbor cell of the service cell. When the identification information of the neighbor cell to be judged exists in the neighbor cell list of the service cell, the base station judges that the neighbor cell to be judged is not the missing neighbor cell of the service cell. The identification information of the neighbor cell to be determined may be BCCH and BSIC of the neighbor cell to be determined.

Fig. 2 is a schematic flow chart of a specific embodiment of a method for identifying a missed neighbor cell provided by the present invention, and as shown in fig. 2, the specific steps include:

step 201: acquiring a measurement report reported by a mobile station of a serving cell; the measurement report includes information about the neighbor of the serving cell.

Specifically, the implementation process of this step may include the base station broadcasting a BA list, where the BA list includes BCCH frequency points and BSICs of each neighboring cell of the serving cell; the mobile station of the service cell receives the BA list and measures the level value of BCCH frequency point of each adjacent cell in the BA list; the mobile station of the service cell reports a measurement report to the base station, wherein the measurement report comprises level values, BCCH and BSIC of adjacent cells with the strongest level values; the base station receives the measurement report.

Step 202: and counting the adjacent cells with the occurrence frequency exceeding a preset threshold value according to the currently acquired relevant information of the adjacent cells.

Specifically, the implementation process of this step may include that the currently acquired relevant information of the neighboring cell includes BCCH and BSIC of the neighboring cell; the base station takes BCCH and BSIC of the adjacent region as identification information of the adjacent region; the base station calculates the occurrence frequency value of each adjacent cell according to the currently acquired identification information of each adjacent cell; and the base station judges the adjacent cell of which the occurrence frequency value exceeds a preset threshold value.

Step 203: and judging whether the neighbor cell with the occurrence frequency exceeding the preset threshold exists in a neighbor cell list of the service cell.

Specifically, the step may include the base station determining whether there is an identifier of a neighboring cell whose frequency of occurrence exceeds a preset threshold in a neighboring cell list of the serving cell; when the identification information of the neighbor cells with the occurrence frequency exceeding the preset threshold does not exist in the neighbor cell list of the serving cell, the base station determines that the neighbor cells with the occurrence frequency exceeding the preset threshold do not exist in the neighbor cell list of the serving cell; the identifier information of the neighbor cell whose occurrence frequency exceeds the preset threshold may be BCCH and BSIC of the neighbor cell whose occurrence frequency exceeds the preset threshold.

When the neighbor cell whose occurrence frequency exceeds the preset threshold does not exist in the neighbor cell list of the serving cell, executing step 204, otherwise, entering step 205: finishing; when the neighbor cells with the occurrence frequency exceeding the preset threshold exist in the neighbor cell list of the serving cell, the neighbor cells with the occurrence frequency exceeding the preset threshold are configured as the neighbor cells of the serving cell.

Step 204: and determining the neighbor cells which do not exist in the neighbor cell list of the service cell and have the occurrence frequency exceeding a preset threshold value as the missing neighbor cells of the service cell.

Specifically, the base station determines a neighbor cell, which does not exist in the neighbor cell list of the serving cell and has a frequency exceeding a preset threshold, as a missed neighbor cell of the serving cell.

In order to realize the method, the invention discloses a device for identifying the missing neighbor cell.

Fig. 3 is a schematic structural diagram of a device for identifying a missed neighbor cell according to an embodiment of the present invention, and as shown in fig. 3, the device for identifying a missed neighbor cell includes:

an obtaining module 301, configured to obtain a measurement report reported by a mobile station of a serving cell; the measurement report includes information related to a neighboring cell of the serving cell;

a counting module 302, configured to count the neighboring cell whose occurrence frequency exceeds a preset threshold according to the currently acquired relevant information of the neighboring cell, and use the neighboring cell whose occurrence frequency exceeds the preset threshold as a neighboring cell to be determined;

a determining module 303, configured to determine the neighboring cell to be determined that is not present in the neighboring cell list of the serving cell as the missing-configured neighboring cell of the serving cell.

Further, the counting module 302 is specifically configured to use a broadcast control channel BCCH and a base station identity code BSIC of the neighboring cell as the identification information of the neighboring cell; calculating the occurrence frequency value of each neighboring cell according to the currently acquired identification information of each neighboring cell; and taking the neighbor cell with the occurrence frequency value exceeding a preset threshold value as a neighbor cell to be judged.

Further, the determining module 303 is specifically configured to determine whether the identifier information of the neighboring cell to be determined exists in the neighboring cell list of the serving cell; and when the identification information of the neighbor cell to be judged does not exist in the neighbor cell list, confirming the neighbor cell to be judged as the missing neighbor cell of the service cell.

In practical applications, the obtaining module 301, the statistical module 302, and the determining module 303 may be implemented by a Central Processing Unit (CPU), a microprocessor Unit (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like located in a server.

Another method for identifying a missed neighbor cell provided in the embodiment of the present invention is shown below.

In the embodiment of the invention, when a behavior event generated by a mobile station of a service cell meets a first preset condition, a target cell of the behavior event is judged to be a neighboring cell of the service cell; and when the judged neighbor cell does not exist in the neighbor cell list of the service cell, determining the judged neighbor cell as the missing neighbor cell of the service cell.

Fig. 4 is a flowchart of another method for identifying a missed neighbor cell according to an embodiment of the present invention, where as shown in fig. 4, the method for identifying a missed neighbor cell includes:

step 401: when the behavior event generated by the mobile station of the service cell meets a first preset condition, the target cell of the behavior event is judged to be the adjacent cell of the service cell.

Specifically, the step may include the base station determining whether a behavior event occurring at the mobile station of the serving cell satisfies a first preset condition; and when the first preset condition is met, the base station judges that the target cell of the behavior event is the adjacent cell of the service cell.

Specifically, the implementation manner of the step of the base station determining whether the behavior event occurring in the mobile station of the serving cell satisfies the first preset condition may include a first manner, a second manner, and a third manner.

The method comprises the steps that a base station judges whether a mobile station of a service cell has a first switching behavior according to recorded switching related information; when the mobile station does not generate the first switching action, the base station returns to execute the step of judging whether the mobile station of the service cell generates the first switching action according to the recorded switching related information; when the mobile station generates a first switching behavior, the base station judges whether the mobile station generates a second switching behavior according to the switching related information; when the mobile station does not generate the second switching action, the base station returns to execute the step of judging whether the mobile station of the service cell generates the first switching action according to the recorded switching related information; when the mobile station generates a second switching behavior, the base station judges whether the time interval between the first switching behavior and the second switching behavior is lower than a first preset time interval or not according to the switching related information; when the time interval is not less than a first preset time interval, the base station determines that the action event generated by the mobile station of the service cell does not meet a first preset condition, and the base station returns to execute the step of judging whether the mobile station of the service cell generates a first switching action according to the recorded switching related information; when the time interval is lower than a first preset time interval, the base station determines that the behavior event of the mobile station of the serving cell meets a first preset condition.

It should be noted that the first handover behavior refers to a handover of a mobile station of a serving cell from the serving cell to a first target cell; the second handover behavior is a handover of the mobile station from a first target cell to a second target cell. The second target cell is a cell other than the serving cell. For example, the serving cell is an a cell, the first handover action may be a handover of the mobile station from the a cell to a B cell, and the second handover action may be a handover of the mobile station from the B cell to a C cell.

Specifically, the recording process of the handover-related information may include that, when a handover action occurs to a mobile station of a serving cell, the base station records information related to the handover action of the mobile station. The information is handover-related information, which may include identification information of the mobile station, the original cell and the target cell of the handover action of the mobile station, and the time of the handover action.

Specifically, the preset time interval may be set according to an actual situation, for example, the serving cell is an a cell, the first handover behavior may be a handover of the mobile station from the a cell to a B cell, and the second handover behavior may be a handover of the mobile station from the B cell to a C cell; if it is known from multiple actual measurements that the time interval between two handover behaviors is less than 3 seconds, the target cell of the second handover behavior, i.e. the cell C, may be the neighboring cell of the original cell of the first handover behavior, i.e. the cell a, and at this time, the first preset time interval may be set to 3 seconds.

The base station judges whether the mobile station of the service cell is powered off or not according to the recorded power on/off related information; when the mobile station does not have the power-off behavior, the base station returns the recorded power-on and power-off related information to judge whether the mobile station of the service cell has the power-off behavior; when the mobile station is powered off, the base station judges whether the mobile station is powered on or not according to the power on and off related information; when the mobile station does not generate the power-on behavior, the base station returns the power-on related information according to the record to judge whether the mobile station of the service cell generates the power-off behavior; when the mobile station is powered on, the base station judges whether the time interval between the power-off action and the power-on action is lower than a second preset time interval or not according to the power-on and power-off related information; when the time interval is not less than a second preset time interval, the base station determines that the action event generated by the mobile station of the service cell does not meet a first preset condition, and the base station returns to the step of judging whether the mobile station of the service cell is powered off or not according to the recorded power on/off related information; and when the time interval is lower than a second preset time interval, the base station determines that the behavior event of the mobile station of the serving cell meets a first preset condition.

Specifically, the recording process of the power on/off related information may include that, when the mobile station in the serving cell performs the power off behavior and the power on behavior, the base station records the related information of the power off behavior and the power on behavior of the mobile station. The information is the related information of power on and power off, and the related information may include the identification information of the mobile station, the cell where the mobile station is located when the power off behavior and the power on behavior occur, and the time when the power off behavior and the power on behavior occur.

Specifically, the second preset time interval may be set according to an actual situation, for example, if it is determined according to a multiple power-on/power-off event that occurs to the mobile station, when the time interval between the power-off behavior and the power-on behavior of the mobile station is smaller than 30 seconds, the geographic location where the mobile station is located when the mobile station is powered on is generally near the geographic location where the mobile station is located when the mobile station is powered off, that is, in this case, the cell where the mobile station is located when the mobile station is powered off is generally adjacent to the cell where the mobile station is located when the mobile station is powered on, and at this time, the second preset time interval may be set to 30 seconds.

Judging whether the mobile station of the service cell has weak coverage drop call behavior or not by the base station according to the recorded drop call reconnection related information; when the mobile station does not have the weak coverage call drop behavior, the base station returns to execute the step of judging whether the mobile station of the service cell has the weak coverage call drop behavior according to the recorded call drop reconnection related information; when the mobile station has a weak coverage dropped call behavior, the base station judges whether the mobile station of the service cell has a call behavior according to the dropped call reconnection related information; when the mobile station does not have a call behavior, the base station returns to execute the step of judging whether the mobile station of the service cell has a weak coverage call drop behavior according to the recorded call drop reconnection related information; when the mobile station has a call behavior, the base station judges whether the time interval between the weak coverage call drop behavior and the call behavior is lower than a third preset time interval or not according to the call drop reconnection related information; when the time interval is not less than a third preset time interval, the base station determines that the behavior event generated by the mobile station of the service cell does not meet a first preset condition, and the base station returns to execute the step of judging whether the mobile station of the service cell has a weak coverage drop call behavior according to the recorded drop call reconnection related information; and when the time interval is lower than a third preset time interval, the base station determines that the behavior event of the mobile station of the serving cell meets a first preset condition.

It should be noted that the weak coverage dropped call behavior refers to a dropped call behavior caused by the level value of the serving cell of the mobile station being less than minus 90 db mv.

Specifically, the recording process of the information related to the reconnection can include that when the mobile station in the serving cell has a weak coverage dropped call behavior and a call behavior, the base station records the information related to the weak coverage dropped call behavior and the call behavior of the mobile station. The information is the information related to the dropped call reconnection, and the related information may include identification information of the mobile station, a cell where the mobile station is located when the mobile station has a weak coverage dropped call behavior and a call behavior, and a time when the mobile station has a weak coverage dropped call behavior and a call behavior.

Specifically, the third preset time interval may be set according to an actual situation, for example, if it is determined according to a multiple dropped call reconnection event occurring on the mobile station, when the time interval between the weak coverage dropped call behavior occurring on the mobile station and the call behavior is less than 30 seconds, the geographical location where the mobile station is located when the weak coverage dropped call behavior occurs on the mobile station is usually near the geographical location where the mobile station is located when the call behavior occurs on the mobile station, that is, in this case, the cell where the mobile station is located when the mobile station has the weak coverage dropped call behavior is usually adjacent to the cell where the mobile station is located when the call behavior occurs on the mobile station, and at this time, the third preset time interval may be set to 30 seconds.

Specifically, the implementation manner of the step of determining that the target cell of the behavior event is the neighboring cell of the serving cell when the first preset condition is met may include a first manner, a second manner, and a third manner.

In a first manner, when the behavior event is a handover event, the handover event refers to an event where the first handover behavior and the second handover behavior occur, and when the first preset condition is met, it is determined that the target cell of the behavior event is a neighboring cell of the serving cell, where the base station determines that the target cell of the second handover behavior is a neighboring cell of the serving cell when a time interval between the first handover behavior and the second handover behavior is lower than a first preset time interval. For example, the serving cell is a cell a, and the first handover behavior may be a handover of the mobile station from the cell a to a cell B; the second handover behavior may be a handover of the mobile station from the B cell to the C cell, and when a time interval between the first handover behavior and the second handover behavior is lower than a first preset time interval, the base station determines that a target cell of the second handover behavior is the C cell, and may be an original cell of the first handover behavior, that is, a neighboring cell of the a cell.

In a second mode, when the behavior event is a power on/off event, the power on/off event refers to the event that the power off behavior and the power on behavior occur, and when the first preset condition is met, the target cell of the behavior event is determined to be a neighboring cell of the serving cell. If the serving cell is a cell A, the mobile station is in the cell A when the weak coverage drop call behavior occurs; when the mobile station has a call behavior, the base station determines that the cell where the mobile station is located when the call behavior occurs, namely the cell B, may be the cell where the mobile station is located when the weak coverage drop-call behavior occurs, namely the cell A, when the time interval between the weak coverage drop-call behavior and the call behavior is lower than a third preset time interval.

And when the time interval between the weak coverage drop-call behavior and the call behavior is lower than a third preset time interval, the base station determines that the cell where the mobile station is located when the call behavior occurs is the cell of the serving cell. If the serving cell is a cell A, the mobile station is in the cell A when the weak coverage drop call behavior occurs; when the mobile station has a call behavior, the base station determines that the cell where the mobile station is located when the call behavior occurs, namely the cell B, may be the cell where the mobile station is located when the weak coverage drop-call behavior occurs, namely the cell A, when the time interval between the weak coverage drop-call behavior and the call behavior is lower than a third preset time interval.

Step 402: and when the judged neighbor cell does not exist in the neighbor cell list of the service cell, determining the judged neighbor cell as the missing neighbor cell of the service cell.

Specifically, the step may include the base station determining whether the determined neighbor cell exists in a neighbor cell list of the serving cell; and when the judged neighbor cell does not exist in the neighbor cell list, the base station determines the judged neighbor cell as the missing neighbor cell of the service cell. That is, the base station judges whether the judged neighbor cell is configured as the neighbor cell of the serving cell, determines the judged neighbor cell as the neighbor cell of the serving cell when determining that the judged neighbor cell is not configured as the neighbor cell of the serving cell, and otherwise, determines that the judged neighbor cell is not the neighbor cell of the serving cell. Therefore, the missing adjacent cells can be identified automatically and accurately in real time without consuming a large amount of manpower, and the identification efficiency and the accuracy of the identification result are improved.

In the present step, for example, when the target cell of the second handover behavior, i.e. the cell C, does not exist in the neighbor cell list of the serving cell, i.e. the cell a, the base station may determine the cell C as the missed neighbor cell of the serving cell, i.e. the cell a. Or, when the cell B where the mobile station is located when the power-on behavior occurs does not exist in the neighbor cell list of the serving cell a, the base station may determine the cell B where the mobile station is located when the power-on behavior occurs as the missed neighbor cell of the serving cell a. Or, when the cell B where the mobile station is located when the call behavior occurs does not exist in the neighbor cell list of the serving cell a, the base station may determine the cell B where the mobile station is located when the call behavior occurs as the missed neighbor cell of the serving cell a.

It should be noted that, in order to identify the missing neighboring cell more accurately and definitely, a specific implementation process of this step may include: when the judged neighbor cell does not exist in the neighbor cell list of the serving cell, the base station judges whether the times of the behavior events of the mobile station of the serving cell meet a second preset condition or not; and when the times meet a second preset condition, the base station determines the judged neighbor cell as the missing neighbor cell of the serving cell. That is, when the mobile station has a corresponding behavior event for many times, the base station determines the determined neighbor cell as the missing neighbor cell of the serving cell. Therefore, the base station can more accurately identify the missing neighbor cell of the serving cell, and the accuracy of the identification result is improved.

Specifically, when the behavior event is a handover event, the specific implementation process of this step may include that, when the mobile station performs the second handover behavior, the base station performs an add operation on the corresponding first value; wherein, the different first time values are used for recording the times of different switching events of the mobile station of the service cell; the base station performs an adding operation on the second numerical value; the second value is used for recording the times of the switching events of the mobile station of the service cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station judges whether the ratio of the first numerical value to the second numerical value exceeds a preset ratio or not; and when the ratio exceeds a preset ratio, the base station takes the judged neighbor cell as the missing-configuration neighbor cell of the serving cell. It should be noted that the preset ratio may be set according to an actual situation, for example, if the ratio exceeds 10, and the determined neighboring cell is usually the serving cell that has missed the neighboring cell, the preset ratio may be set to 10.

Specifically, when the behavior event is a power-on/off event, the specific implementation process of this step may include that, when the mobile station performs a power-on behavior, the base station performs an add operation on the corresponding third numerical value; the different third numerical value is used for recording the times of different power-on and power-off events of the mobile station of the service cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station judges whether the third numerical value exceeds the preset numerical value or not; and when the third numerical value exceeds the preset numerical value, the base station takes the judged neighbor cell as the missing neighbor cell of the service cell.

Specifically, when the behavior event is a call drop and call reconnection event, the specific implementation process of this step may include that, when the mobile station has a call behavior, the base station performs an add operation on the corresponding fourth numerical value; the different fourth numerical value is used for recording the times of different call drop and call re-calling events of the mobile station of the serving cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station judges whether the fourth numerical value exceeds the preset numerical value or not; and when the fourth numerical value exceeds the preset numerical value, the base station takes the judged neighbor cell as the missing neighbor cell of the service cell. It should be noted that the preset number of times may be set according to an actual situation, for example, if the preset number of times exceeds 20, and a determined serving cell, which is usually a neighboring cell, misses a neighboring cell, the preset number of times may be set to 20.

It should be noted that, in order to identify the missing-matching neighboring cell with a strong level value, the specific implementation process of this step may include: when the judged neighbor cell does not exist in the neighbor cell list of the serving cell, the base station judges whether the level value of the judged neighbor cell measured by the mobile station in the serving cell before the mobile station of the serving cell has a behavior event exceeds a preset level value; and when the level value exceeds a preset level value, the base station determines the judged neighbor cell as the missing neighbor cell of the serving cell. Therefore, the base station can identify the neighbor cell which is missed to be matched and has a stronger level value. The preset level value may be set according to an actual situation, for example, when the level value of the neighboring cell measured by the mobile station in the serving cell exceeds negative 90 db mv, and when the mobile station is handed over from the serving cell to the neighboring cell, the communication quality of the mobile station may be ensured, in this case, the neighboring cell may be configured as the neighboring cell of the serving cell, and therefore, in this case, the preset level value may be set to negative 90 db mv.

It should be noted that, in order to more accurately and certainly identify the missing neighbor cell with a strong level value, a specific implementation process of this step may include that, when there is no determined neighbor cell in the neighbor cell list of the serving cell, the base station determines whether the number of times of occurrence of a behavior event of the mobile station of the serving cell satisfies a second preset condition, and whether the level value of the determined neighbor cell measured by the mobile station in the serving cell before the occurrence of the behavior event of the mobile station of the serving cell exceeds a preset level value; and when the times meet a second preset condition and the level value exceeds a preset level value, the base station determines the judged neighbor cell as the missing neighbor cell of the serving cell. Therefore, the base station can identify the missing-matching adjacent cell with the stronger level value more accurately.

Specifically, when the behavior event is a handover event, the specific implementation process of this step may include that, when the mobile station performs the second handover behavior, the base station performs an add operation on the corresponding first value; the different first time values are used for recording the times of different switching events of the mobile station of the service cell; the base station performs an adding operation on the second numerical value; the second value is used for recording the times of the switching events of the mobile station of the service cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station judges whether the ratio of the first numerical value to the second numerical value exceeds a preset ratio or not; when the ratio exceeds a preset ratio, the base station acquires the level value of the judged adjacent cell measured by the mobile station in the serving cell before the occurrence of the switching event; the base station calculates the average level value of all the level values obtained currently; the base station judges whether the average level value exceeds a preset level value or not; and when the average level value exceeds a preset level value, the base station determines the judged neighbor cell as the missing neighbor cell of the serving cell.

Specifically, when the behavior event is a power-on/off event, the specific implementation process of this step may include that, when the mobile station performs a power-on behavior, the base station performs an add operation on the corresponding third numerical value; the different third numerical value is used for recording the times of different power-on and power-off events of the mobile station of the service cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station acquires the level value of the judged neighbor cell measured by the mobile station in the service cell before the power-on and power-off event occurs; the base station calculates the average level value of all the level values obtained currently; the base station judges whether the average level value exceeds a preset level value or not; when the average level value exceeds the preset level value, the base station judges whether the third time value exceeds the preset time value; and when the third numerical value exceeds the preset numerical value, the base station takes the judged neighbor cell as the missing neighbor cell of the service cell.

Specifically, when the behavior event is a call drop and call reconnection event, the specific implementation process of this step may include that, when the mobile station has a call behavior, the base station performs an add operation on the corresponding fourth numerical value; the different fourth numerical value is used for recording the times of different call drop and call re-calling events of the mobile station of the serving cell; when the judged neighbor cell does not exist in the neighbor cell list of the service cell, the base station acquires the level value of the judged neighbor cell measured by the mobile station in the service cell before the call drop event occurs and the call is resumed; the base station calculates the average level value of all the level values obtained currently; the base station judges whether the average level value exceeds a preset level value or not; when the average level value exceeds the preset level value, the base station judges whether the fourth numerical value exceeds the preset numerical value; and when the fourth numerical value exceeds the preset numerical value, the base station takes the judged neighbor cell as the missing neighbor cell of the service cell.
