[0024] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0025] Since most of the Femto base stations are used to compensate for indoor coverage blind area, and are used in indoor coverage environment, and the neighbor cells of the Femto cell are automatically configured by the Femto base station according to the wireless environment measured by the antenna, there are redundant neighbor cells.

[0026] The method for optimizing a neighbor cell of a home base station cell provided by the present application deletes redundant neighbor cells according to the characteristics of the Femto cell. Since the indoor building, such as the indoor signal compensation of the user's personal home, has a certain regularity in the motion track of the resident user, and the switching locations mainly occur at places such as from the gate to the indoor, from the indoor to the window or the balcony, etc. In addition to the necessary switching location from the gate to the indoor, if the indoor Femto signal coverage is strong, it is unnecessary to add these switching neighbor cells, and increase the unnecessary switching times. Meanwhile, the switching time interval of the two cells at the switching point from the gate to the indoor will be larger than the switching time interval of the two cells at the switching point of the window or the balcony, and therefore, these characteristics can be used to delete the redundant neighbor cells. The following will be described in combination with specific examples.

[0027] Figure 1 A flow chart of a method for optimizing a neighbor cell of a home base station cell is shown. As shown in Figure 1 the method comprises the following steps:

[0028] In step S101, a current neighbor cell list of the home base station cell is acquired.

[0029] The femto cell is a cell covered by a femto base station, and a current neighbor cell list of the femto cell is a list of existing neighbor cells determined by the femto base station, specifically, the list is automatically configured by the femto base station according to a wireless environment measured by an antenna, and records which neighbor cells currently exist in the femto cell. The list may have redundant neighbor cells, and thus, a neighbor cell optimization process is needed. Specifically, the optimization process can be performed by using the neighbor cell optimization process scheme of the femto cell provided by the embodiment, and specifically, the step acquires a current neighbor cell list of the femto cell, and the neighbor cell list records at least one neighbor cell.

[0030] In step S102, for any neighbor cell recorded in the neighbor cell list, a switching time point when the femto cell and the neighbor cell switch to each other and a cut-out level value corresponding to a cut-out femto cell are acquired within a preset time period.

[0031] In an actual application scenario, there may be three cases of switching from the femto cell to the neighbor cell, switching from the neighbor cell to the femto cell, and switching from the neighbor cell to the neighbor cell. The switching from the femto cell to the neighbor cell is referred to as the cut-out femto cell, and the switching from the neighbor cell to the femto cell is referred to as the cut-in femto cell. When switching, the cut-out or cut-in may occur between the femto cell and the same neighbor cell, or the cut-out or cut-in may occur between multiple neighbor cells and the femto cell, for example, switching from the neighbor cell A to the femto cell and switching from the femto cell to the neighbor cell B. Here, only an example is given, and the example does not have any limiting effect.

[0032] In order to accurately optimize the neighbor cell, for any neighbor cell recorded in the neighbor cell list, a switching time point when the femto cell and the neighbor cell switch to each other and a cut-out level value corresponding to a cut-out femto cell are acquired within a preset time period. It should be noted that the step acquires the switching time point when the femto cell switches to the neighbor cell, the switching time point when the neighbor cell switches to the femto cell, and the cut-out level value when the femto cell switches to the neighbor cell.

[0033] The preset time period is a long enough time period, so as to collect enough data, such as the switching time point and the cut-out level value, for optimization processing.

[0034] In step S103, whether the neighbor cell is a redundant neighbor cell is determined according to the switching time point and the cut-out level value. If yes, step S104 is performed.

[0035] After the switching time point and the cut-out level value are acquired, whether the neighbor cell is a redundant neighbor cell can be determined according to the switching time point and the cut-out level value, wherein the redundant neighbor cell specifically refers to a cell with a poor neighbor cell signal, and switching to the cell can easily cause a call drop and frequent switching.

[0036] In step S104, the neighbor cell is deleted from the neighbor cell list corresponding to the home base station cell.

[0037] In a case where it is determined that the neighbor cell is a redundant neighbor cell, the neighbor cell is deleted from the neighbor cell list corresponding to the Femto cell. By deleting the neighbor cell from the neighbor cell list, the neighbor relationship is released, and the Femto cell can be prevented from switching to the neighbor cell, thereby reducing the number of switching times of the user staying in the Femto cell and improving the user experience.

[0038] According to the method provided in the above embodiment of the present application, the current neighbor cell list of the home base station cell is acquired; for any neighbor cell recorded in the neighbor cell list, the switching time point and the cut-out level value of the home base station cell when the home base station cell and the neighbor cell switch to each other within a preset time period are acquired; whether the neighbor cell is a redundant neighbor cell is determined according to the switching time point and the cut-out level value; and if the neighbor cell is a redundant neighbor cell, the neighbor cell is deleted from the neighbor cell list corresponding to the home base station cell. According to the user mobility law, the redundant neighbor cell is removed, so that the switching relationship is simplified and effective, and the user experience is improved due to the elimination of the confusion of the neighbor relationship and the complexity of the switching chain.

[0039] Figure 2 A flow chart of a neighbor cell optimization processing method of a home base station cell provided in another embodiment of the present application is shown. As shown in the figure, the method comprises the following steps: Figure 2

[0040] In step S201, the current neighbor cell list of the home base station cell is acquired.

[0041] The home base station cell (Femto cell) is a cell covered by a home base station (Femto base station), and the current neighbor cell list of the Femto cell is a list of existing neighbor cells determined by the Femto base station. The neighbor cell list is automatically configured by the Femto base station according to the wireless environment measured by the antenna. The neighbor cell list records the current neighbor cells of the Femto cell, and the neighbor cell list can include redundant neighbor cells. Therefore, the neighbor cell optimization processing is required. Specifically, the neighbor cell optimization processing can be performed by the neighbor cell optimization processing scheme of the home base station cell provided in the embodiment. Specifically, the current neighbor cell list of the Femto cell is acquired in this step, and at least one neighbor cell is recorded in the neighbor cell list.

[0042] ​Step S202, for any neighbor cell recorded in the neighbor cell list, the switching time point when the home base station cell and the neighbor cell switch each other and the cut-out level value corresponding to the cut-out home base station cell collected in a preset time period are acquired.

[0043] In the actual application scenario, there can be three cases of Femto cell switching to a neighbor cell, neighbor cell switching to a Femto cell and neighbor cell switching to a neighbor cell, Femto cell switching to a neighbor cell is called cut-out Femto cell, and neighbor cell switching to a Femto cell is called cut-in Femto cell. When switching, it can be that the cut-out or cut-in occurs between the Femto cell and the same neighbor cell, or the cut-out or cut-in occurs between multiple neighbor cells and the Femto cell, for example, switching from a neighbor cell A to a Femto cell and switching from the Femto cell to a neighbor cell B, which is only an example for illustration and does not have any limiting effect.

[0044] In order to accurately optimize the neighbor cell, for any neighbor cell recorded in the neighbor cell list, the switching time point when the home base station cell and the neighbor cell switch each other and the cut-out level value corresponding to the cut-out home base station cell collected in a preset time period are acquired. It should be noted that this step acquires the switching time point when the Femto cell switches to the neighbor cell and the switching time point when the neighbor cell switches to the Femto cell, and the level value of the cut-out Femto cell when the Femto cell switches to the neighbor cell.

[0045] The preset time period is a long enough time period so as to collect enough data such as switching time point and cut-out level value for optimization processing.

[0046] Suppose that nM neighbor cells are recorded in the neighbor cell list, then the acquired switching time points are as follows:

[0047]

[0048] Wherein, T nMf_NM represents the nM switching time point when the nM neighbor cell switches between the Femto cell and the neighbor cell, and the switching time point includes the switching time point when the Femto cell switches to the neighbor cell and / or the switching time point when the neighbor cell switches to the Femto cell. The data of each row represents the switching time point of one neighbor cell, and the number of switching time points acquired by each neighbor cell can be the same or different. Taking the first row of data as an example, it represents that the first neighbor cell has acquired 0-N1 switching time points.

[0049] The acquired cut-out level value corresponding to the cut-out Femto cell is as follows:

[0050]

[0051] Wherein, RSRP nMf_LMrepresents the Lth level value of the handover level when the nthM neighbor cell occurs the handover from the Femto cell to the neighbor cell, and the data of each row represents the corresponding handover level value of each neighbor cell. The number of the handover level values obtained by each neighbor cell can be the same or different. For example, the first row of data represents that the 1st neighbor cell obtains 0-L1 handover level values.

[0052] In step S203, the handover time interval between the adjacent two handover time points is calculated, and the average value corresponding to the handover time interval is calculated.

[0053] In order to accurately analyze whether a neighbor cell is a redundant neighbor cell, the handover time interval between the adjacent two handover time points is calculated, and the handover time interval corresponding to each neighbor cell is finally obtained as follows:

[0054]

[0055] wherein, t nMf_N1 = T nMf_N1 -T nMf_N2 , and the others are similar. The data of each row represents the corresponding handover time interval of each neighbor cell.

[0056] After the handover time interval corresponding to each neighbor cell is calculated, the average value is calculated according to the handover time interval corresponding to the neighbor cell, and the average value of the handover time interval corresponding to the nM neighbor cells is represented as follows:

[0057] t_avg n1f ,t_avg n2f …t_avg nMf

[0058] wherein, and the others are similar.

[0059] In step S204, the handover level average value of the handover Femto cell is calculated according to the handover level value.

[0060] For each neighbor cell, the handover level average value of the handover Femto cell is calculated according to the handover level value obtained by the neighbor cell, and for the nM neighbor cells, the handover level average value of the handover Femto cell is represented as follows:

[0061] RSRP_avg n1f ,RSRP_avg n2f …RSRP_avg nMf

[0062] wherein, and the others are similar.

[0063] In step S205, the proportion value of the handover time interval less than the preset time interval threshold value is calculated.

[0064] The preset time interval threshold is a preset time interval judgment threshold, and a specific value can be set by a person skilled in the art according to experience. The proportion value can effectively improve the judgment accuracy of the redundant neighbor cell, and avoid the situation that the switching time interval is too long, the average value is affected, and the judgment of the redundant neighbor cell is inaccurate.

[0065] The proportion value of the switching time interval less than the preset time interval threshold is calculated by using the following formula:

[0066]

[0067] Wherein, P is the proportion value, t i is the i-th switching time interval, τ is the preset time interval threshold, and M is the number of switching time intervals.

[0068] In combination with nM neighbor cells, the calculated proportion value is as follows:

[0069] P n1f ,P n2f …P nMf

[0070] Wherein, Other similar, wherein, NM switching time interval number, t nMf_i represents the i-th switching time interval of the nM-th neighbor cell, P nMf represents the proportion value of the nM-th neighbor cell, and τ is the preset time interval threshold.

[0071] The execution order of steps S203 and S204 is not limited in this embodiment. Steps S203 and S204 can be executed simultaneously, step S204 can be executed first and then step S203, or step S203 can be executed first and then step S204, which is not limited here.

[0072] The execution order of steps S204 and S205 is not limited in this embodiment. Steps S204 and S205 can be executed simultaneously, step S204 can be executed first and then step S205, or step S205 can be executed first and then step S204, which is not limited here. In addition, after the switching time interval is calculated in step S203, the proportion value of the switching time interval less than the preset time interval threshold can be directly calculated.

[0073] In step S206, it is judged whether the average value corresponding to the switching time interval is less than the preset switching time interval threshold, whether the average value of the switching level is greater than the preset level threshold, and whether the proportion value is greater than the preset proportion value. If yes, step S207 is executed.

[0074] The preset switching time interval threshold is Thr_τ, the preset level threshold is Thr_rsrp, and the preset proportion value is Thr_p. The above single values are preset decision thresholds, which respectively define the critical conditions for the neighbor cell to be a redundant neighbor cell

[0075] For the neighbor cell nM, the average value corresponding to the switching time interval calculated above is compared with the preset switching time interval threshold, the average value of the cut-out level is compared with the preset level threshold, and the proportion value is compared with the preset proportion value. If the average value corresponding to the switching time interval is less than the preset switching time interval threshold, the average value of the cut-out level is greater than the preset level threshold, and the proportion value is greater than the preset proportion value, that is, t_avg nMf <Thr_τ, and RSRP avgnMf >Thr_rsrp, and P nMf >Thr_p, the neighbor cell nM is determined to be a redundant neighbor cell.

[0076] In step S207, it is determined that the neighbor cell is a redundant neighbor cell, and the neighbor cell is deleted from the neighbor cell list corresponding to the home base station cell.

[0077] If it is determined that the average value corresponding to the switching time interval is less than the preset switching time interval threshold, the average value of the cut-out level is greater than the preset level threshold, and the proportion value is greater than the preset proportion value, it can be determined that the neighbor cell is a redundant neighbor cell, and the neighbor cell is deleted from the neighbor cell list corresponding to the Femto cell. By deleting the neighbor cell from the neighbor cell list, the neighbor relationship is resolved, the number of handovers of the Femto cell is reduced, and the user experience is improved.

[0078] In step S208, it is determined whether the connected state performance index is degraded. If yes, step S209 is performed.

[0079] After deleting the neighbor cell from the neighbor cell list corresponding to the home base station cell, the connected state performance index needs to be observed. If the connected state performance index is degraded, it indicates that the deleted neighbor cell is not a redundant neighbor cell, and the deleted neighbor cell needs to be restored. The connected state performance index includes one or more of the following indexes: network rate and handover success rate. For the network rate, degradation means that the network rate is reduced. For the handover success rate, degradation means that the handover success rate is low.

[0080] In step S209, it is determined that the neighbor cell is not a redundant neighbor cell, and the neighbor cell is restored to the neighbor cell list corresponding to the home base station cell.

[0081] In the case where it is determined that the connected state performance index is degraded, it can be determined that the deleted neighbor cell is not a redundant neighbor cell, and the deleted neighbor cell needs to be restored. Specifically, the neighbor cell is restored to the neighbor cell list corresponding to the home base station cell.

[0082] The present application eliminates redundant neighboring cells according to user mobility rules, thereby ensuring the simplification and effectiveness of handover relations, avoiding user perception reduction caused by complex handover chains and chaotic neighboring cell relations.

[0085] The second acquisition module 302 is adapted to acquire the handover time point and the handout level value corresponding to the handout home base station cell when the home base station cell and the neighboring cell are mutually switched within a preset time period for any neighboring cell recorded in the neighboring cell list.

[0088] Optionally, the first judgment module is further adapted to: calculate the handover time interval between two adjacent handover time points, and calculate the average value corresponding to the handover time interval.

[0089] According to the handout level value, the average value of the handout level of the handout home base station cell is calculated.

[0090] The proportion value of the handover time interval less than the preset time interval threshold value is calculated.

[0091] According to the average value corresponding to the handover time interval, the average value of the handout level, and the proportion value, it is judged whether the neighboring cell is a redundant neighboring cell.

[0092] Optionally, the first judgment module is further adapted to: calculate the proportion value of the handover time interval less than the preset time interval threshold value by using the following formula

[0093]

[0095] ​​Optionally, the first judgment module is further adapted to: determine whether the average value corresponding to the switching time interval is less than the preset switching time interval threshold, whether the average value of the switching level is greater than the preset level threshold, and whether the ratio value is greater than the preset ratio value.
