[0038] A baseband processing unit (BBU, Base Band Unite) is an important component of a wireless base station. In order to reduce the power consumption of the BBU, an energy-saving method is adopted, including improving the use efficiency of baseband resources in the BBU. Specifically, in the related art, the use of baseband resources of a baseband board is matched with real-time service load, and cells are concentrated on part of the baseband board for processing, and the baseband resources of the remaining baseband board are closed. The above scheme needs to migrate cells between baseband boards. Each time the cells are migrated between baseband boards, since the process of re-establishing the cells by a new board card, re-matching the service state and the like all need to consume a certain time, a certain time of service interruption will be caused. When the matching between the service load and the baseband resources reaches a critical point, due to the fluctuation of the service volume, the cells will be repeatedly migrated between the board cards, causing frequent service interruption.

[0039] Based on this, in various embodiments of the present application, when the condition for starting cell migration is reached, the first base station determines the change feature corresponding to the historical service load of the first baseband board card of the first base station in a first time period, and based on the change feature, controls the first baseband board card to start cell migration or maintain a normal working state. The starting time point of the first time period is represented as the time point when the service load on the first baseband board card reaches the condition for starting cell migration. Based on the above scheme, when the service volume carried by the cells and the baseband resources configured for the cells are in a critical state of matching, the adoption of the above scheme can effectively avoid the repeated migration of the cells between the baseband board cards, thereby avoiding frequent service interruption.

[0040] The terms related to the embodiments of the present application are defined as follows:

[0041] Normal working state: when each baseband board card of a base station carries an original cell, the baseband board card is in a normal working state, and the cell carried on the baseband board card is also in a normal working state;

[0042] Pooled working state: when part of the baseband boards in the base station bear all the cells through cell migration, the part of the baseband boards bearing all the cells is in a pooled working state, and usually, the part of the baseband boards bearing all the cells is called a pooled baseband board. Correspondingly, the cell completing cell migration is also in a pooled working state.

[0043] Cell migration: the process of changing a cell from a normal working state to a pooled working state, that is, the process of migrating a cell from an original baseband board to a pooled baseband board through front-haul data interaction between baseband boards, which is called cell migration.

[0044] Cell recovery: the process of recovering a cell from a pooled working state to a normal working state, that is, the process of migrating a cell from a pooled baseband board to an original baseband board, which is called cell recovery.

[0045] Embodiments of the present application provide a cell migration method applied to a first base station, as shown in the figure, the method comprises: Figure 1

[0046] Step 101: determining a first change feature in the case of reaching a condition for starting cell migration.

[0047] The first change feature represents a change feature corresponding to historical service load of the first baseband board of the first base station in a first time period; and the starting time point of the first time period represents a time point when the service load on the first baseband board reaches the condition for starting cell migration.

[0048] In actual application, each baseband board on the first base station bears a corresponding cell, and each baseband board is in a normal working state. By detecting the service load on each baseband board in real time, it is determined whether the condition for starting cell migration is reached. Usually, when determining whether the condition for starting cell migration is reached, the matching of the service load on the baseband board and the baseband resource is mainly considered. If the service load on each baseband board of the first base station does not exceed or will exceed the service load that can be borne by the corresponding baseband resource, it can be considered that the current service load of the first base station does not reach the condition for starting cell migration, each baseband board maintains a normal working state, and the corresponding cell borne on each baseband board also maintains a normal working state; if the service load on the first baseband board exceeds or will exceed the service load that can be borne by the corresponding baseband resource, and there is a second baseband board that can offload the service load on the first baseband board, it can be determined that the condition for starting cell migration is reached, and at this time, the historical service load data of the first baseband board is obtained.

[0049] ​In the embodiment of the present application, the historical service load data of the baseband board is acquired to determine the change of the service load of the baseband board in the historical same period. For example, taking an hour as a unit of statistics interval, the service load of the first baseband board at 18:15 in the afternoon of a day reaches the condition of starting cell migration, and the cell migration of the first baseband board is needed, so the service load data of the first baseband board from 18:00 to 19:00 in the afternoon of the previous day, the previous week, the previous month or the previous year is called out to determine the corresponding change characteristics.

[0050] In actual application, the historical service load data can be stored in the form of a data trend chart for easy calling and viewing.

[0051] Step 102: based on the first change characteristics, controlling the first baseband board to start cell migration or maintain a normal working state.

[0052] After determining the corresponding change characteristics based on the historical service load data, whether the first baseband board is controlled to start cell migration or maintain a normal working state is determined according to the determined change characteristics.

[0053] In an embodiment, the step of controlling the first baseband board to start cell migration or maintain a normal working state based on the first change characteristics comprises:

[0054] In the case that the first change characteristics represent the increase of the service load, the first baseband board is controlled to maintain a normal working state.

[0055] That is, if the historical service load data of the first baseband board in the historical same period presents a trend of increase, it means that the service load of the cell is likely to increase in the future, and at this time, the first baseband board is controlled to maintain a normal working state without cell migration, so as to avoid the cell restoration after cell migration due to the increase of the service load, leading to repeated cell migration and frequent service interruption.

[0056] In the case that the first change characteristics represent the decrease or invariability of the service load, the first baseband board is controlled to start cell migration or maintain a normal working state based on second change characteristics.

[0057] The second change characteristics represent the change characteristics of the service load of the first baseband board after reaching the condition of starting cell migration.

[0058] Here, if the historical service load data of the first baseband board in the historical same period presents a trend of decrease or invariability, the duration of the trend is further observed to determine whether the first baseband board is controlled to start cell migration or maintain a normal working state.

[0059] Therefore, in an embodiment, the controlling the first baseband board card to start cell migration or maintain normal working state based on the second change feature comprises:

[0060] controlling the first baseband board card to start cell migration in a case where the first duration of the service load dropping or remaining unchanged exceeds a set duration.

[0061] controlling the first baseband board card to maintain normal working state in a case where the first duration does not exceed the set duration.

[0062] Here, the second change feature can be understood as the change feature of the service load of the first baseband board card after it is determined in step 101 that the condition for starting cell migration is met. In actual application, after the condition for starting cell migration is met, further action is suspended, and the change of the service load on the first baseband board card is continuously observed. If the service load remains dropping or remaining unchanged for a relatively long time, it is considered that the service load will continue to be at a relatively low load for a short time, and the first baseband board card is controlled to start cell migration at this time, which is likely to trigger cell recovery in a short time, and therefore, cell migration is started. If the service load presents a dropping or remaining unchanged trend for a short time and then presents a growing trend, it is considered that the service load will continue to rise in a short time, and the first baseband board card is controlled to start cell migration at this time, which is unlikely to trigger cell recovery in a short time, and therefore, cell migration is not started.

[0063] In actual application, the second change feature is obtained by taking the set duration as an observation window, and in an embodiment, the set duration is greater than the first duration; the first duration represents a set multiple of the cell switching duration.

[0064] For example, the set duration greater than a dozen cell switching durations is taken as an observation window to obtain the second change feature. Here, the set duration is greater than a dozen cell switching durations, and such a setting can ensure that cell migration is not repeatedly performed in a short time.

[0065] The above scheme can effectively avoid repeated migration of a cell between baseband board cards and frequent service interruption by judging whether to start cell migration when the service amount of the cell and the baseband resources configured for the cell are in a matching critical state. Figure 2 An implementation process of a cell migration method provided by an embodiment of the present application is shown.

[0066] Since the cell migration will cause the service to be interrupted temporarily, in actual application, in order to avoid the influence on the user caused by the service interruption, it is possible to only wish to perform the cell migration when the service load is low, for example, performing the cell migration in the early morning in a day and restoring the normal working state of the cell when the service load is high. Based on this, in an embodiment, in the case that the first duration of the service load dropping or being unchanged represented by the second change feature exceeds a set duration, the first baseband board card is controlled to start the cell migration, including:

[0067] In the case that the first duration exceeds the set duration and the first duration is greater than a second duration, the first baseband board card is controlled to start the cell migration; wherein,

[0068] The second duration represents the duration of the service load dropping or being unchanged corresponding to the last time when the first baseband board card starts the cell migration in a set time period.

[0069] For example, the set time period is set to 1 natural day, when the first baseband board card starts the cell migration for the first time in a day, the duration t1 of the service load dropping or being unchanged at this time is recorded. When the corresponding cell restores the normal working state and the corresponding service load reaches the condition of starting the cell migration for the second time in a day, the duration t2 of the service load dropping or being unchanged at this time is recorded, and whether t2 is much greater than t1 is judged, if t2 is much greater than t1, the first baseband board card starts the cell migration for the second time, otherwise, the first baseband board card maintains the normal working state, and so on.

[0070] The above scheme can be understood as that a punishment mechanism is set for the start of the cell migration, so that as the number of times of the service load reaching the condition of starting the cell migration increases, only when the service load continuously drops or is unchanged, the cell migration is performed, thereby limiting the number of times of the cell migration in the set time period.

[0071] In addition, in an embodiment, the method further includes:

[0072] In the case that the number of times of starting the cell migration by the first baseband board card in the set time period is greater than a set number of times, the first baseband board card is prohibited to start the cell migration.

[0073] Here, the upper limit of the number of times of starting the cell migration in the set time period is also set, so as to limit the number of times of the cell migration in the set time period. For example, the maximum migration number m in a day is set, and a counter is started, the count value of the counter is increased by 1 every time the cell migration is started in a day, and when the count value of the counter reaches the maximum migration number m, the cell migration is not started regardless of whether the service load reaches the condition of starting the cell migration.

[0074] In an embodiment, the method further comprises:

[0075] In the case that the first baseband board card is in the pooled working state, when the service load of the originally carried cell on the first baseband board card reaches the condition for starting cell recovery, the first baseband board card is controlled to return to the normal working state.

[0076] In actual application, in the case that the first baseband board card is in the pooled working state, the service load of the originally carried cell on the first baseband board card is detected in real time to determine whether the corresponding service load reaches the condition for starting cell recovery. Generally, when determining whether the condition for starting cell recovery is reached, if the service load of the cell in the pooled state has caused or will cause the load of the baseband board card currently carrying the cell to be too large, it can be considered that the corresponding service load reaches the condition for starting cell recovery, and the first baseband board card needs to return to the normal working state, otherwise, the first baseband board card still maintains in the pooled working state. After the first baseband board card returns to the normal working state, the condition for starting cell migration can be determined again according to the service load of the cell and the baseband resource configured for the cell. Figure 2 The flowchart shown in the figure is used to determine whether to start cell migration when the service load of the cell and the baseband resource configured for the cell are in a critical matching state.

[0077] Figure 3 The implementation flow of the cell recovery method provided by the embodiment of the application is shown.

[0078] In actual application, the cell migration method of the embodiment of the application can be implemented on the baseband board card, the main control board or the network management.
