BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In the embodiment of the present invention, after the mobility parameter is adjusted, the system does not achieve the expected effect, and a parameter processing method and device based on the load balancing mechanism are provided. The solution may be performed by a server that is jointly connected by two adjacent cells, or may be performed by a base station of a cell in two adjacent cells. The connection relationship between each device or module in the embodiment of the present invention may be a wired connection or a wireless connection, such as a coupled connection. The method and apparatus are described below by way of specific examples. This embodiment provides a parameter processing method based on a load balancing mechanism, which can be used for load balancing between two adjacent cells in the same base station, and can also be used for load balancing between two adjacent cells in different base stations. One of the two cells may be a serving cell and the other is a neighboring cell, but the equivalent replacement thereof is also included in the protection scope of the present invention. 1 is a flowchart of a parameter processing method based on a load balancing mechanism according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps: Step S102: Detect performance states of two neighboring cells; Step S104: When the performance state detected in step S102 reaches the handover threshold, the handover parameters (ie, mobility parameters) of the two neighboring cells are modified, and the modified association value of the handover parameter is cached; Step S106, the modified handover parameter is detected at the specified time. Whether the performance status meets the recovery threshold requirement, and if not, the modified switching parameter is rolled back according to the modified associated value cached in step S104. The above specified time may be timed by a timer, or may be set, but is not limited to these timing modes. Through the above steps, the modified associated value is cached when the switching parameter is modified, so that the modified switching parameter can be rolled back if the system performance state after the specified time does not reach the expected effect. The invention solves the problem that the system is in an unstable state in the case that the system still fails to achieve the expected effect after the switching parameter adjustment in the prior art, so that the controllability and stability of the configuration parameters related to the mobility load balancing function are higher, reaching Better maintain and ensure the stability and robustness of the system. The performance status mentioned above may be a load difference or a load ratio of two adjacent cells, but is not limited thereto. For example, the number of loads of two adjacent cells may be the same as long as the performance state of the cell can be expressed. Within the scope of protection of the present invention. For the sake of simplicity in the actual operation, the performance state in the following embodiments is described by taking the load difference of two adjacent cells as an example. As a preferred embodiment, the handover parameter of at least one of the two neighboring cells in the embodiment reaches a set maximum value. Based on this, in actual implementation, two adjacent handovers may be attempted to be modified multiple times. The parameter is used to achieve the expected effect. If the modified switching parameter reaches the set maximum value and the system still does not achieve the expected effect, the above-mentioned fallback mechanism can be used for processing. In this case, the step-by-step method can be used, for example, The modification of the associated value is performed each time the switching parameter is modified, and the switching parameter is gradually rolled back according to the saved modified associated value, and finally the switching parameter is not restored. With this implementation, the system can be made more secure and stable in balancing the load of two adjacent cells. As a preferred embodiment, the modified association value cached in step S104 may be a handover parameter before modification of each of the two adjacent cells, or may be a modified offset value of each of the two adjacent cells. When the modified association value is a handover parameter before the modification of each of the two neighboring cells, the handover parameter that is modified according to the modified association value in step S106 may be to restore the modified handover parameters of the two adjacent cells to The switching parameters before the respective modification; when the modified association value is the modified offset value of each of the two neighboring cells, the modified handover parameter according to the modified association value in step S106 may be that the two adjacent cells are respectively The modified switching parameters are incrementally modified according to the respective modified offset values, and the switching parameters before the respective modifications are obtained. The incremental modification corresponds to the inverse modification modified in step S104, and the incremental modification may be to increase the modified offset value, or may reduce the modified offset value. In the above manner, the rollback mode can be made more flexible. However, the use of the modified offset value as a way to modify the associated value will save storage space. Therefore, in the following embodiments, the method of modifying the associated value using the modified offset value will be used as an example. However, this is not to be construed as limiting the scope of the invention. The two cells are two peer cells. For convenience of description, one of them is used as a serving cell, and the other is a neighboring cell of the serving cell. In this case, the modified offset value in step S104 can be cached in The serving cell may also be cached in the neighboring cell. Of course, the modified offset value may also be cached in both cells. In the preferred embodiment, in order to save storage space, the modification in step S104 is offset. The value buffer is described in the serving cell as an example. When the modified offset value in the step S104 is buffered in the serving cell, the backoff mode in the step S106 may be that the serving cell incrementally modifies the modified offset value and the modified handover parameter to obtain the serving cell before modification. The handover parameter is sent by the serving cell to the neighboring cell, where the fallback notification carries the modified offset value of the neighboring cell; after receiving the fallback notification, the neighboring zone changes the modified offset value of the neighboring cell to the neighboring zone. The modified switching parameters are incrementally modified to obtain the switching parameters before the modification of the neighboring cell. When the modified offset value in the step S104 is buffered in the serving cell, the backoff mode in the step S106 may be that the serving cell first sends a fallback notification to the neighboring cell, where the backoff notification carries the modified offset value of the neighboring cell. After receiving the fallback notification, the neighboring area incrementally modifies the modified offset value of the neighboring area and the modified switching parameter of the neighboring area to obtain the switching parameter before the modification of the neighboring area, and sends the fallback to the serving cell successfully. After receiving the fallback success response, the serving cell incrementally modifies the modified offset value and the modified handover parameter to obtain the handover parameter before the modification of the serving cell. Through the above steps, the rollback mode of the handover parameter can be made more reliable, and multiple rollback modes can also make the rollback process more flexible. In this embodiment, a parameter processing device based on the load balancing mechanism is further provided, and the device is used to implement the foregoing embodiments and preferred embodiments, and details are not described herein. As used hereinafter, the term "module" may implement a combination of software and/or hardware of a predetermined function.

Incremental modification, get the switching parameters before each modification. For convenience of description, one of the two neighboring cells is a serving cell, and the other is a neighboring cell of the serving cell. Based on this, the second backoff unit 2104 may be set at a base station where the serving cell is located. The second back-off unit 2104 includes: a first modification sub-unit, configured to incrementally modify the modified offset value of the serving cell itself and the modified handover parameter to obtain a handover parameter before the modification of the serving cell; The modification sub-unit is connected, and is configured to send a fallback notification to the neighboring area, where the back-off notification carries the modified offset value of the neighboring area; of course, correspondingly, the base station of the neighboring area also has a second fallback The unit 2104, at this time, the second back-off unit 2104 on the neighboring area includes: a second modifying sub-unit 21043, connected to the sending sub-unit, configured to receive the modified offset value of the neighboring area after receiving the back-off notification The modified switching parameters are incrementally modified to obtain the switching parameters before the neighboring area is modified.

The back-off module 210 on the base station where the serving cell is located includes: a sending unit, configured to send a fallback to the neighboring cell. The notification, where the fallback notification carries the modified offset value of the neighboring cell; the backoff unit is configured to receive the modified offset value of the serving cell itself and the modified switch after receiving the fallback success response returned by the neighboring cell The parameter is incrementally modified to obtain the handover parameter before the modification of the serving cell; the fallback module 210 on the base station where the neighboring cell is located includes: a parameter recovery unit, configured to: after receiving the fallback notification, modify the modified offset value of the neighboring cell The subsequent switching parameters are incrementally modified to obtain the switching parameters before the modification of the neighboring cell; the response unit is connected to the parameter recovery unit, and is set to obtain the switching parameter before the modification of the neighboring area by the parameter recovery unit, and then send a successful response to the serving cell. . Preferably, the performance state detected by the first detecting module 202 is a load difference or a load ratio of two adjacent cells. The modified handover parameter of at least one of the two adjacent cells in the modification module 204 reaches a set maximum value. Through the above device, the modified associated value is cached when the switching parameter is modified, so that the modified switching parameter can be rolled back after the system performance state after the specified time does not achieve the expected effect, and the current solution is resolved. In the technology, if the system still fails to achieve the expected effect after the adjustment of the switching parameters, the system will be in an unstable state, so that the controllability and stability of the configuration parameters related to the mobility load balancing function are higher, and the better. Maintain and ensure the stability and robustness of the system. The following description is made in conjunction with the preferred embodiments, which are combined with the above-described embodiments and preferred embodiments thereof. Embodiment 1 In the preferred embodiment, an implementation method with a fallback function based on a mobility load (ie, load) equalization mechanism is provided. The implementation method is specifically: after modifying the handover parameter, if the performance state of the system reaches the expected (ie, the recovery threshold is reached) within a specified time (for example, one or more specified time periods or time windows), the handover parameter is maintained. modify. If the performance status of the system still fails to meet the expected performance, the system will revert the modified configuration of the previous cache to the specified range. The preferred embodiment mainly includes the following steps: Step S2, performing periodic detection on the load (ie, load) state of the system network, and processing one of two neighboring cells (in the embodiment, the serving cell is taken as an example) The cell dynamically monitors and updates the load status of the cell and its neighboring cells. Step S4, after the load state of the serving cell and its neighboring area reaches a certain load difference, or after reaching a certain load state ratio and other performance state parameters, the serving cell starts a mobility load balancing function, and services according to a predetermined policy. The cell and the selected neighboring cell modify the switching parameters, and the parameters can be cached before being modified. The predetermined policy may be: modifying a handover parameter of the serving cell to make it easier for the access device that resides in the cell to switch out, and modifying the handover parameter of the corresponding neighboring cell to make the access device easier to switch access. Of course, it can also be an equivalent replacement of the above predetermined strategy. Step S6: The control module (ie, the foregoing second detecting module 208) performs one or more time window effect monitoring after determining that the switching parameters of the serving cell and the neighboring cell are modified (for example, detecting at a time point of the system cycle) Whether the performance status of the serving cell and the neighboring cell reaches the recovery threshold), dynamically updating the current load status information of the serving cell and the neighboring cell. In step S8, if it is detected that the service cell load status information is significantly improved (for example, when a predetermined recovery threshold is met), the mobility load balancing function is considered to have achieved the effect that the current handover parameter modification is saved. In step S10, if the monitoring of the load state information of the serving cell is not significantly improved, that is, the recovery threshold is not met, it is considered that the mobility load balancing function cannot perform the proper effect, and setting according to the switching parameter is difficult to satisfy the load balancing of the entire system. Therefore, the previously modified switching parameters should be rolled back. By adopting the processing mechanism of the preferred embodiment, in the case that the processing of the load balancing function does not achieve the expected effect, the robustness of the system and the stability of the configuration data are ensured by processing the modified switching parameters. In the embodiment, the source side cell is used as the serving cell, and the target side cell is used as the neighboring cell of the serving cell. Correspondingly, the source side processing unit refers to the front and back subsystems of the source side cell, and the target side processing unit. It refers to the front and back subsystems that process the target side cell. 5 is a schematic diagram of a connection relationship between a source side cell and a target side cell according to a preferred embodiment of the present invention. As shown in FIG. 5, the schematic diagram includes a source side cell 501 of a source side processing unit and a target side including a target side processing unit. Cell 502. The source side cell 501 and the target side cell 502 may belong to the same base station or belong to different base stations. The preferred embodiment is described by taking the serving cell and its neighboring cell in the same base station as an example. FIG. 6 is a schematic structural diagram of two neighboring cells in the same base station according to a preferred embodiment of the present invention. As shown in FIG. 6, the schematic diagram includes: a source side execution module 603 corresponding to a source side cell and a corresponding target side cell. The target side execution module 606; the base station further includes: an algorithm module 601, a measurement module 602, an interface module 604, and a background 605, wherein the background 605 is a background processing unit of the source side cell and the target side cell common base station. In the preferred embodiment, the base station where the two cells are located and the interface in the background adopt a common interface. In the process of the modification and the rollback processing of the handover parameters, the base station sends a notification message to the background 605, and the background 605 modifies the relevant parameters and then synchronizes to the source side execution module 603 or the target side execution module 606 of the foreground. Ensure the consistency of the front and back data. The algorithm module 601 and the measurement module 602 complete the functions of the first detection module 202 or the second detection module 208, and the background 605 completes the functions of the modification module 204, the cache module 206, and the fallback module 210. The module in FIG. 6 above will be further described below in conjunction with specific embodiments. 7 is a flowchart of mobility load balancing processing of two neighboring cells in the same base station according to a preferred embodiment 2 of the present invention. As shown in FIG. 7, the flow includes the following steps (steps S702 to S716): Step S702, determining whether the function period is reached, if yes, executing step S704; if not, continuing monitoring, and repeating this step. The function period is that the measurement module 602 monitors whether the duration of two neighboring cells reaches a set time, for example, a timer that periodically starts the mobility load balancing function in the system, and the measurement module 602 directly performs the source side cell. When the load information measurement and update of the neighboring area is performed, the source side execution module 603 determines whether the timer expires, and if the timer expires, the process proceeds to step S704. The present embodiment is only described with the source side as the originating side, but the equivalent execution manner, for example, the following steps are performed by the target side execution module 606 as the originating side, and should also be included in the protection scope of the present invention. Step S704, the source side execution module 603 first calls the measurement module 602 to detect the load status of the system, and then invokes the algorithm module 601 to perform an algorithm decision on the result measured by the measurement module 602, and determines whether the result satisfies the set mobility load balance. The algorithm determines the threshold. In this embodiment, it is determined whether the load difference between the serving cell and the neighboring cell reaches the condition threshold. If not, the timer is restarted, and the process proceeds to step S702. If yes, the process proceeds to step S706. In step S706, the source side execution module 603 notifies the background 605 to modify the cell handover parameter through the interface module 604 and performs caching (for example, the modification flag may be performed at the value before the handover parameter modification, or the modified offset value may also be stored. After the modification is successful, the background 605 returns a confirmation message, and then proceeds to step S708. Step S708, after obtaining the confirmation message, the source side execution module 603 notifies the corresponding neighboring target side execution module 606 through the interface module 604, and the execution module notifies the background 605 to modify and cache the switching parameters through the interface module 604 (when the above step S706 When the modified offset value is stored in the cache, the modification flag may be performed only at the value before the switching parameter modification; when the above step S706 is cached, the modification flag is performed at the value before the switching parameter modification, The modified offset value is stored), and after completion, step S710 is performed. The order of the above steps S706 and S708 can be reversed. Step S710, after completing the modification of the handover parameter in step S708, the source side execution module 603 or the target side execution module 606 starts a timer for effect determination, and monitors whether the timer of the effect determination arrives (ie, whether the monitoring time window arrives). If the timer expires, then go to step S712; if no, continue monitoring, repeat this step. In step S712, the source side execution module 603 controls the measurement module 602 to perform real-time monitoring on the load status of the network, and the control algorithm module 601 determines whether the result measured by the measurement module 602 reaches an expected condition (for example, reaching recovery). If there is any, it indicates that the load status of the current serving cell is significantly improved, and step S714 is performed; otherwise, step S716 is performed. In step S714, the source side execution module 603 controls the interface module 604 to notify the background 605 to retain the parameter values after the previous switching parameter modification. In step S716, the source side execution module 603 controls the interface module 604 to notify the background 605 to perform the rollback processing according to the previous modification flag or the modified offset value. After the background 605 returns the rollback success response, the background 605 sends a fallback message to the target of the corresponding neighboring area. The side execution module 606 notifies that it also performs the rollback process of the relevant modified parameter, so as to restore the original parameter configuration, wherein the back-off message carries the modified associated value cached in the previous S706. Of course, step S714 and step S716 may be that the source side execution module 603 or the target side execution module 606 first notifies the corresponding neighboring area to perform the rollback processing first, and then performs the backoff of the party after receiving the response information of the successful backoff of the other party. deal with. In this embodiment, the handover parameter modification process of two adjacent cells in the same base station is improved, and the modified association value is cached when the handover parameter is modified, so that the system performance state after the specified time does not reach the expected effect. In the case of the method, the modified handover parameter can be retired, which solves the problem that the system is in an unstable state in the prior art that the system still fails to achieve the expected effect after the adjustment of the handover parameter, so that the mobility load is balanced. The controllability and stability of the function-related configuration parameters are higher, achieving better maintenance and ensuring system stability and robustness.

In the preferred embodiment, the base station and the background interface where the two cells are located adopt a common interface. During the modification and rollback processing of the handover parameters, the base station where the cell is located sends a notification message to the corresponding background, and the background performs the modification of the relevant parameters and then synchronizes to the corresponding control module in the foreground to ensure the consistency of the front and back data. Sexual. The module in FIG. 8 above will be further described below in conjunction with specific embodiments.

As shown in FIG. 9, the process includes the following steps (step S902 to step S916): Step S902, determining whether the function period is reached, and if yes, Go to step S904; if no, continue monitoring and repeat this step. The function period refers to whether the measurement module 802 monitors whether the duration of two neighboring cells reaches a set time, for example, a timer that periodically starts the mobility load balancing function in the system, and the measurement module 802 directly performs the source side cell. Measurement and update of load information with its neighbors. When the source side control module 803 determines whether the timer has expired, if the timer expires, the process proceeds to step S904. Step S904, the source side control module 803 first calls the measurement module 802 to detect the load condition of the system, and then invokes the algorithm module 801 to perform an algorithm decision on the measurement result of the measurement module 802, and determines whether the result satisfies the set mobility load balance. The algorithm determines the threshold. In this embodiment, it is determined whether the load difference between the serving cell and the neighboring cell reaches the condition threshold. If not, the timer is restarted, and the process proceeds to step S902. If yes, the process proceeds to step S906. The present embodiment is only described with the source side as the originating side, but the equivalent implementation manner, for example, the following steps are performed by the target side control module 806 as the originating side, and should also be included in the protection scope of the present invention. In step S906, the source side control module 803 notifies the target side control module 806 of the corresponding neighboring area to modify the cell switching parameter by using the source side interface module 804 and the target side interface module 807, and the target side control module 806 passes the target side interface module 807 to the target. The side background 808 initiates the switching parameter modification, and the confirmation message returned by the target side background 808 is received, and the confirmation message is fed back to the source side control module 803 through the target side interface module 807 and the source side interface module 804, and the process proceeds to step S908. In step S908, the source-side control module 803 notifies the source-side background 805 of the modification of the handover parameter by the source-side interface module 804, and performs a cache process for modifying the associated value, where the direction and size of the modification are modified. It can be calculated by the algorithm module 801, and after successful, the process proceeds to step S910. Step S910, after completing the modification of the handover parameter in step S908, the source-side control module 803 starts a timer for the effect determination, and monitors whether the timer of the effect determination arrives (ie, monitors whether the time window arrives), if the timer expires , then proceed to step S912; if no, continue monitoring, repeat this step. In step S912, the source-side control module 803 controls the measurement module 802 to perform real-time monitoring on the load status of the network, and the control algorithm module 801 determines whether the result measured by the measurement module 802 reaches an expected condition. If yes, the current load status of the serving cell has If the improvement is significant, step S914 is performed, otherwise step S916 is performed. In step S914, the source side control module 803 notifies the target side control module 806 to retain the parameter value of the previous switching parameter modification through the source side interface module 804 and the target side interface module 807, and controls the source side background 805 to be reserved by the source side interface module 804. The parameter value after the previous switching parameter modification; the target side control module 806 controls the target side background 808 through the target side interface module 807 to perform the process of retaining the modified parameter value. In step S916, the source-side control module 803 sends the back-end message to the target-side control module 806 to perform the rollback processing according to the previous modification flag or the modified offset value by the source-side interface module 804 and the target-side interface module 807. The retrace message carries the modified association value cached in the previous S908; the target-side control module 806 initiates the rollback processing to the target-side background 808 through the target-side interface module 807 according to the modified association value cached in the S908 carried in the back-off message. After returning the fallback success response to the source side control module 803; after receiving the fallback success response, the source side control module 803 controls the source side background 805 to perform back according to the previous modification flag or the modified offset value. The processing is returned, and the original parameter configuration is restored. 10 is a flowchart of a mobility load balancing process for modifying a target side cell handover parameter after two neighboring cells are between different base stations according to a preferred embodiment of the present invention, and the modification manner is to modify the source side cell handover parameter first. As shown in FIG. 10, the process includes: Step S1002 to Step S1016, the specific steps are as follows: Step S1002: Determine whether the function period is reached, if yes, execute step S1004; if no, continue monitoring, and repeat this step. The function period refers to whether the measurement module 802 monitors whether the duration of two neighboring cells reaches a set time, for example, a timer that periodically starts the mobility load balancing function in the system, and the measurement module 802 directly performs the source side cell. Measurement and update of load information with its neighbors. When the source side control module 803 determines whether the timer has expired, if it is, the process proceeds to step S1004. In step S1004, the source side control module 803 first calls the measurement module 802 to detect the load status of the system, and then invokes the algorithm module 801 to perform an algorithm decision on the measurement result of the measurement module 802, and determines whether the measurement result satisfies the set mobility load. The equalization algorithm determines the threshold. In this embodiment, it is determined whether the load difference between the serving cell and the neighboring cell reaches the condition threshold. If not, the timer is restarted, and the process proceeds to step S1002. If the process reaches 1j, the process proceeds to step S1006. In step S1006, the source-side control module 803 notifies the source-side background 805 of the modification of the handover parameter by the source-side interface module 804, and performs a cache process for modifying the associated value. After the modification succeeds, the source side returns an acknowledgement message to the 805. The source side control module 803, wherein the direction and size of the modification of the handover parameter can be calculated by the algorithm module 801. Step S1008: After receiving the confirmation message, the source side control module 803 notifies the target side control module 806 of the corresponding neighboring area to modify the cell handover parameter by using the source side interface module 804 and the target side interface module 807, and the target side control module 806 passes the target. The side interface module 807 initiates the switching parameter modification to the target side background 808. After the modification succeeds, the process proceeds to step S1010. Step S1010, after completing the modification of the switching parameter of step S1008, the source-side control module 803 starts the timer of the effect determination, and monitors whether the timer of the effect determination is up, if the timer expires, then proceeds to step S1012; , continue monitoring, repeat this step. In step S1012, the source-side control module 803 controls the measurement module 802 to monitor the load status of the network in real time, and the control algorithm module 801 determines whether the measurement result of the measurement module 802 meets an expected condition. If yes, the current service cell load status is If the improvement is significant, step S1014 is performed, otherwise step S1016 is performed. In step S1014, the source side control module 803 controls the source side background 805 to retain the parameter value of the previous switching parameter modification through the source side interface module 804, and the source side control module 803 also notifies the source side interface module 804 and the target side interface module 807. The target side control module 806 retains the previously changed parameter values of the switching parameters, and the target side control module 806 controls the target side background 808 to retain the modified parameter values through the target side interface module 807. In step S1016, the source side control module 803 controls the source side background 805 to perform the rollback processing according to the previous modification flag or the modified offset value, and sends the target back to the target through the source side interface module 804 and the target side interface module 807. The side control module 806 performs a back-off message of the rollback process according to the previous modification flag or the modified offset value, where the back-off message carries the modified association value cached in the previous S1006; the target-side control module 806 is configured according to the back-off message. The modified association value cached in the carried S1006 is initiated by the target side interface module 807 to the target side background 808, thereby restoring the original parameter configuration. In this embodiment, the handover parameter modification process of two adjacent cells between different base stations is improved, and the modified association value is cached when the handover parameter is modified, so that the system performance state after the specified time does not achieve the expected effect. In the case of the method, the modified handover parameter can be retired, which solves the problem that the system is in an unstable state in the prior art that the system still fails to achieve the expected effect after the adjustment of the handover parameter, so that the mobility load is balanced.
