Detailed Description
First, terms referred to in the present application will be explained.
A cell, also called a cell, is a basic unit of coverage of a wireless network, and is an area covered by a base station or a part of a base station in a cellular mobile communication system, in which a user equipment can communicate with the base station through a wireless channel, and generally one base station corresponds to three cells.
The neighboring cell refers to a neighboring cell, and each cell has a neighboring cell.
Cell handover refers to a process of handover of a user equipment from one cell to another cell. When the ue is in a service connection state and maintains a service, the original cell may not be able to continue to provide the service for the ue when the ue moves from one cell to another cell. Or, in the service process, the signal strength of the new cell is much higher than that of the original cell, and at this time, in order to enable the user to obtain better experience, the user may be switched from the original cell to the new cell.
The X2 interface refers to an interface between a base station and a base station that supports data and signaling.
The X2 link refers to a communication link formed by the interconnection of the base stations through the X2 interface.
The prior art related to the present application will be described and analyzed in detail below.
In the prior art, the neighbor cell switching generally is to determine that a candidate neighbor cell satisfies a current switching condition of a target cell when a user equipment detects that a signal intensity of the candidate neighbor cell is higher than a signal intensity of the target cell by a preset signal intensity threshold, and after the candidate neighbor cell satisfies the current switching condition of the target cell, the user equipment determines the candidate neighbor cell satisfying the current switching condition as the target neighbor cell and sends a request for switching to the target neighbor cell to a base station to switch to the target neighbor cell with higher signal intensity. In the neighbor cell switching method, the user equipment performs switching based on the signal strength of the target cell and the candidate neighbor cell, and the user equipment cannot acquire the actual service performance of the neighbor cell. In practical applications, a neighboring cell with high signal strength may have problems of large signal interference, high network load, device failure, and the like, and may not provide better network service for the user equipment. Therefore, the existing neighbor cell switching method cannot acquire the actual service performance of the neighbor cell and cannot select the target neighbor cell for switching according to the actual service performance of the neighbor cell, thereby causing the problem that better user experience after the user equipment switches the cell cannot be guaranteed.
Therefore, in the face of the problems in the prior art, the inventor finds out through creative research that the technical scheme of the application is provided, and aims to solve the problems in the prior art. In order to ensure that the user equipment obtains better user experience after switching the cells, the current service performance value of each candidate neighbor cell needs to be determined, and whether the candidate neighbor cell meets the switching condition is determined together according to the current service performance value and the signal strength of each candidate neighbor cell, so that the target neighbor cell determined by the user equipment from the candidate neighbor cell meeting the switching condition has better actual service performance than the target cell, and further, the user equipment can obtain better user experience after being switched to the target neighbor cell. Therefore, the method includes the steps of obtaining a target cell where the user equipment is located and at least one candidate neighbor cell of the target cell, obtaining current network sensing information of each candidate neighbor cell, determining a current service performance value of the corresponding candidate neighbor cell according to each current network sensing information, determining a current switching condition related offset value corresponding to the current service performance value of each candidate neighbor cell, sending each current switching condition related offset value to the user equipment, wherein each current switching condition related offset value is used for indicating the user equipment to obtain a current switching condition of the target cell and signal strength of each candidate neighbor cell, and determining the target neighbor cell according to the current switching condition of the target cell, the signal strength of each candidate neighbor cell and the current switching condition related offset value of each candidate neighbor cell. The current network perception information of each candidate neighbor cell can reflect the actual service performance of each candidate neighbor cell, and further, the current service performance value of the corresponding candidate neighbor cell determined according to the current network perception information of each candidate neighbor cell can also reflect the actual service performance of each candidate neighbor cell, and the current switching condition related offset value of each candidate neighbor cell corresponds to the current service performance value of each candidate neighbor cell, so that the user equipment determines that the target neighbor cell can ensure that the actual service performance of the target neighbor cell is higher than that of the target cell according to the current switching condition, the signal strength of each candidate neighbor cell and the current switching condition related offset value, and further, the user equipment can be ensured to obtain better user experience after being switched to the target neighbor cell.
The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
A network architecture and an application scenario of the neighbor cell switching method provided in the embodiment of the present application will be described below. When the following description refers to the accompanying drawings, the same data in different drawings represent the same or similar elements, unless otherwise indicated.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, and as shown in fig. 1, a network architecture corresponding to the application scenario provided in the embodiment of the present application includes: the base station 10, the target cell 110, the user equipment 12, and at least one candidate neighbor cell, as in fig. 1, including: a first candidate neighbor 111 and a second candidate neighbor 112. The target cell 110, the first candidate neighbor cell 111 and the second candidate neighbor cell 112 all belong to the base station 10 and are controlled by the base station 10. The user equipment 12 is located in the target cell 110 and may switch to the first candidate neighbor 111 or the second candidate neighbor 112.
After the user equipment 12 accesses the base station 10 through the target cell 110, the base station 10 obtains the target cell 110 where the user equipment 12 is located and each candidate neighboring cell (the first candidate neighboring cell 111 and the second candidate neighboring cell 112) of the target cell 110, and directly obtains current network sensing information of each candidate neighboring cell (for example, receives current network sensing information of each candidate neighboring cell sent by the user equipment in each candidate neighboring cell).
Fig. 2 is a schematic view of another application scenario provided in the embodiment of the present application, and as shown in fig. 2, a network architecture corresponding to the another application scenario provided in the embodiment of the present application includes: base station 10, second base station 11, target cell 110, user equipment 12, and at least one candidate neighbor, as in fig. 2 including: a first candidate neighbor 111 and a third candidate neighbor 113. The target cell 110 and the first candidate neighbor cell 111 belong to the base station 10 and are controlled by the base station 10, and the third candidate neighbor cell 113 belongs to the second base station 11 and is controlled by the second base station 11. The user equipment 12 is located in the target cell 110 and may switch to the first candidate neighbor 111 or the third candidate neighbor 113. The base station 10 and the second base station 11 may be connected by an X2 link.
After the user equipment 12 accesses the base station 10 through the target cell 110, the base station 10 obtains the target cell 110 where the user equipment 12 is located and each candidate neighboring cell (the first candidate neighboring cell 111 and the third candidate neighboring cell 113) of the target cell 110, and directly obtains current network sensing information of the first candidate neighboring cell 111 (for example, receives current network sensing information of the first candidate neighboring cell 111 sent by the user equipment in the first candidate neighboring cell 111), and communicates with the second base station 11 through an X2 link, so as to obtain current network sensing information of the third candidate neighboring cell 113.
In the above two application scenarios, the base station 10 determines the current service performance value of the corresponding candidate neighbor cell according to the current network sensing information of each candidate neighbor cell; determining a current switching condition related offset value corresponding to the current service performance value of each candidate neighbor cell; and sending the relevant offset value of each current switching condition to the user equipment 12, wherein the relevant offset value of each current switching condition is used for indicating the user equipment 12 to acquire the current switching condition of the target cell and the signal strength of each candidate neighbor cell, and determining the target neighbor cell according to the current switching condition, the signal strength of each candidate neighbor cell and the relevant offset value of the current switching condition.
After receiving the relevant offset values of the current switching conditions, the user equipment 12 sends a current switching condition acquisition request to the base station to acquire the current switching conditions of the target cell, measures the signal strength of each candidate neighbor cell in real time, and determines the target neighbor cell according to the current switching conditions of the target cell, the signal strength of each candidate neighbor cell and the relevant offset values of the current switching conditions of each candidate neighbor cell. After the target neighboring cell is determined, a request for switching to the target neighboring cell is sent to the base station 10, and the request for switching to the target neighboring cell includes the flag information of the target neighboring cell.
After receiving the request for switching to the target neighboring cell sent by the user equipment 12, the base station 10 switches to the target neighboring cell in cooperation with the user equipment 12 (or replaces to the target neighboring cell together with the second base station 11 in cooperation with the user equipment 12) according to the flag information of the target neighboring cell in the request for switching to the target neighboring cell.

Embodiments of the present application will be described below with reference to the accompanying drawings. The embodiments described in the following examples do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Example one
Fig. 3 is a flowchart illustrating a method for switching a neighboring cell according to a first embodiment of the present application, where as shown in fig. 3, an execution main body of the present application is a neighboring cell switching device, and the neighboring cell switching device is located in a base station, for example, may be located in an indoor baseband processing unit (BBU) of the base station. The method for switching between adjacent cells provided in this embodiment includes steps 301 to 305.
In this embodiment, the ue is attached to the target cell and communicates with the base station, so that the base station can directly communicate with the ue to obtain the target cell where the ue is located. Meanwhile, the base station can inquire at least one candidate neighbor cell of the target cell in the neighbor cell relation table. The neighbor relation table may be pre-configured in the base station, or may be formed by the base station automatically establishing and adaptively adjusting the neighbor relation according to the operation state of the wireless network and the wireless data collected by the user equipment and the base station.
In this embodiment, the candidate neighbor cell and the target cell may be intra-system neighbor cells, that is, neighbor cells belonging to the same network system; or may be an inter-system neighboring cell, that is, a neighboring cell belonging to different network systems. The candidate neighbor cell and the target cell can also be co-sited neighbor cells, namely neighbor cells belonging to the same base station; or adjacent cells, that is, adjacent cells with similar geographic locations but not belonging to the same base station; the cell may also be a co-coverage neighboring cell, that is, a cell belonging to the same base station but having different frequency points.
In this embodiment, the network awareness information is usage awareness of the user equipment for the cell network service, and may be embodied by each network awareness index and a value of each network awareness index, and the network awareness information may include each network awareness index and a value of each network awareness index. Illustratively, the network awareness information may include an average rate (including an uplink rate and a downlink rate), a maximum rate, a download rate steep drop rate, an abnormal disconnection rate, an access failure rate, an error rate, and the like of the user equipment that is switched to the candidate neighbor cell when using the network within a preset evaluation period. Specifically, the base station may send a network awareness information acquisition request to the user equipment that is switched to the candidate neighbor cell. The network perception acquisition request comprises a preset evaluation period and various network perception indexes which need to be measured by the user equipment. And each user equipment switched to the candidate neighbor cell receives a network perception information acquisition request sent by the base station after being switched to the candidate neighbor cell, measures values of various network perception indexes of network services provided by each candidate neighbor cell in a preset evaluation period, and sends the values to the base station after the measurement is completed. If the number of the user equipment switched to the candidate neighbor cell is multiple, the base station may determine an average value of various network perception index values measured by multiple user equipment as an index value of each network perception index in the current network perception information of the candidate neighbor cell. As the user equipment switches in or out of the cell, the network load situation of the cell changes, and the index value of each network perception index measured by the user changes with the movement of the user, different propagation paths of electromagnetic waves, and the like. And the current network perception information of the candidate neighbor cell is obtained by the real-time measurement of the user equipment switched to the candidate neighbor cell. The base station may periodically obtain current network sensing information of each candidate neighbor cell, and the network sensing information obtained in the current period is the current network sensing information.
In this embodiment, the current service performance value is a quantized value of the real-time service performance of the candidate neighbor cell. The performance value corresponding to each network perception index can be preset, the index value of each network perception index in the current network perception information is multiplied by the corresponding performance value, and the product obtained by multiplication is determined as the current service performance value of the candidate neighbor cell. The performance value corresponding to each network perception index may be related to the size of the index value. For example, for the error rate, when the error rate is set to 0%, the corresponding performance value is 1; when the error rate is 0-10%, the corresponding performance value is 0.9; when the error rate is 10-50%, the corresponding performance value is 0.5; the corresponding performance value is 0 when the error rate is 50-100%. For the access success rate, when the access success rate is set to 0%, the corresponding performance value is 0.
Optionally, in this embodiment, the network awareness information may be good network awareness or poor network awareness, and may be determined by the ue switching to the candidate neighbor according to a network state of the candidate neighbor when the ue uses the network. Specifically, the user equipment that is switched to the candidate neighbor cell may monitor whether each network abnormal condition occurs within a preset evaluation period after being switched to the candidate neighbor cell, where the network abnormal condition may include a dropped connection, an access failure, a steep drop in download rate, and the like. In a preset evaluation period, in the process of uploading the network, if any one or more network abnormal conditions occur in the user equipment switched to the candidate neighbor cell, the network sensing information of the candidate neighbor cell can be determined as poor network sensing and sent to the base station, and if any one network abnormal condition does not occur, the network sensing information of the candidate neighbor cell can be determined as good network sensing and sent to the base station. The base station may receive, within a preset time period, network sensing information sent by all user equipment that is switched to the candidate neighbor cell, and determine the ratio of good network sensing as the current service performance value of the candidate neighbor cell, that is: the current service performance value of the candidate neighbor cell is the number of times of good network perception sent by all user equipment switched to the candidate neighbor cell within a preset time period/the total number of times of network perception information sent by all user equipment switched to the candidate neighbor cell within the preset time period.
In this embodiment, the bias value related to the current handover condition is used to determine whether the candidate neighbor cell satisfies the current handover condition together with the signal strength of the candidate neighbor cell. The current switching condition related offset value corresponds to the current service performance value, which is the embodiment of the actual service performance of the candidate neighbor cells, different current switching condition related offset values are set for the candidate neighbor cells with different actual service performances, and the difficulty degree of meeting the current switching condition of the target cell by each candidate neighbor cell can be controlled. The current handover condition related offset value may have positive and negative values, and may set a positive current handover condition related offset value for a candidate neighboring cell with better actual service performance, and set a negative current handover condition related offset value for a candidate neighboring cell with worse actual service performance. Illustratively, a larger current handover condition bias value is determined for the candidate neighbor with a higher current service performance value, so that the candidate neighbor more easily satisfies the current handover condition. Specifically, the current service performance values of the candidate neighbor cells may be sorted in descending order, the current handover condition related offset value corresponding to the current service performance value of the top 50% is determined as a positive value, the current handover condition related offset value corresponding to the current service performance value of the last 50% is determined as a negative value, and the larger the current service performance value is, the larger the current handover condition related offset value is.
In this embodiment, the base station sends the current handover condition related offset value of each candidate neighbor cell to the user equipment, and the user equipment obtains the current handover condition of the target cell and the signal strength of each candidate neighbor cell in real time after receiving the current handover condition related offset value of each candidate neighbor cell. The current handover condition of the target neighboring cell may include a preset signal strength threshold, and the current handover condition of the target neighboring cell may be: and the signal intensity of the candidate neighbor cell is greater than a preset signal intensity threshold value. The user equipment may determine, as the candidate neighbor cell satisfying the current handover condition, the candidate neighbor cell whose signal strength is greater than or equal to the preset signal strength threshold after superimposing the current handover condition-related bias value of each candidate neighbor cell. Namely, the candidate neighbor cell of which the sum of the signal strength and the bias value related to the previous switching condition is greater than or equal to the preset signal strength threshold value is determined as the candidate neighbor cell meeting the current switching condition.
As an optional implementation manner, the current handover condition of the target neighboring cell may further include a first preset signal strength value and a second preset signal strength value, and the current handover condition of the target neighboring cell may further be: the signal intensity of the target cell is smaller than a first preset signal intensity value, and the signal intensity of the candidate neighbor cell is larger than a second preset signal intensity value. The user equipment may obtain, in real time, the current handover condition and the signal strength of the target cell and the signal strength of each candidate neighbor cell after receiving the current handover condition-related offset value of each candidate neighbor cell, and determine, as a candidate neighbor cell satisfying the current handover condition, the candidate neighbor cell whose sum of the signal strength and the current handover condition-related offset value is greater than or equal to the second preset signal strength when the signal strength of the target cell is less than the first preset signal strength value.
In this embodiment, the user equipment may determine any candidate neighbor cell that satisfies the current handover condition as the target neighbor cell, send a request for cell handover to the target neighbor cell to the base station, where the request for cell handover to the target neighbor cell includes cell flag information of the target neighbor cell
Exemplarily, the current handover condition related offset values of the first candidate neighbor cell and the second candidate neighbor cell received by the user equipment are 5dbm and-5 dbm, respectively, and it can be understood that, at this time, the actual service performance of the first candidate neighbor cell is higher than the actual service performance of the second candidate neighbor cell, the current handover condition obtained for the target cell is-65 dbm, and the signal strengths of the first candidate neighbor cell and the second candidate neighbor cell measured in real time are-70 dbm and-65 dbm, respectively. According to the neighbor cell switching method in the prior art, since the signal strength of the second candidate neighbor cell is higher than that of the first candidate neighbor cell, the user equipment determines the second candidate neighbor cell as the target neighbor cell. However, the actual service performance of the second candidate neighbor cell is not as good as that of the first candidate neighbor cell, and may even be lower than that of the target cell. According to the neighbor cell switching method determined by the application, the user equipment superposes the signal intensity of the first candidate neighbor cell and the current switching condition offset value, then judges whether the superposed signal intensity meets the current switching condition of the target cell, thus, the signal strength of the first candidate neighbor is superimposed with the current handover condition offset value to-70 + 5-65 dbm, the signal strength of the second candidate neighbor is superimposed with the current handover condition offset value to-65-5-70 dbm, the signal strength of the first candidate neighbor cell after superposition satisfies the current handover condition of the target cell, the signal strength of the second candidate neighbor cell after superposition does not satisfy the current handover condition of the target cell, the user equipment determines the first candidate neighbor cell as the target neighbor cell, furthermore, the user equipment can obtain better user experience after being switched to the first candidate neighbor cell.
In the neighbor cell switching method provided in this embodiment, current network sensing information of each candidate neighbor cell is obtained by obtaining a target cell where a user equipment is located and at least one candidate neighbor cell of the target cell, a current service performance value of the corresponding candidate neighbor cell is determined according to each current network sensing information, a current switching condition related offset value corresponding to the current service performance value of each candidate neighbor cell is determined, and each current switching condition related offset value is sent to the user equipment. Because the current network perception information of each candidate neighbor cell can reflect the actual service performance of each candidate neighbor cell, further, the current service performance value of the corresponding candidate neighbor cell determined according to the current network perception information of each candidate neighbor cell can reflect the actual service performance of each candidate neighbor cell, the bias value related to the current handover condition corresponds to the current service performance value of each candidate neighbor cell, the preset signal strength threshold value can be the signal strength value of the target cell which needs to be higher than the target cell in the original handover condition of the target neighbor cell, therefore, the current switching condition of each target adjacent cell is determined according to the current switching condition offset value and the corresponding preset signal strength, the actual service performance of the target adjacent cell can be ensured to be higher than that of the target cell under the current switching condition, furthermore, better user experience can be obtained after the user equipment performs neighbor cell switching according to the current switching condition.

In this embodiment, after the ue switches to the cell controlled by the target base station, the target base station may send a network sensing information acquisition request to the ue. The network perception acquisition request comprises a preset evaluation period and various network perception indexes which need to be measured by the user equipment. After receiving a network sensing information acquisition request sent by a base station, user equipment measures values of various network sensing indexes of network services provided by a cell in which the user equipment is located in a preset evaluation period, and sends the values to a target base station after the measurement is completed.
And 402, receiving current network perception information of the controlled cell sent by other base stations which are in communication connection with the target base station.
In this embodiment, at least one neighboring cell of the target cell may include a neighboring cell, and a base station where the neighboring cell is located is different from a base station where the target cell is located. The other base stations are base stations which are adjacent to the target base station in the geographic position and are in communication connection with the target base station, and the cells controlled by the other base stations may be adjacent to the target cell. Specifically, the target base station and other base stations may be communicatively connected through an X2 link, and the target base station may receive current network awareness information of the controlled cell transmitted by other base stations through an X2 link.
Step 403, the cell controlled by the target base station and the cells controlled by other base stations in communication connection with the target base station are screened to obtain the neighboring cell corresponding to the target cell where the user equipment is located.
In this embodiment, because the cells controlled by other base stations are not necessarily the neighbor cells of the target cell, and the cell controlled by the target base station is also the target cell but not the neighbor cell of the target cell, it is necessary to screen the cell controlled by the target base station and the cells controlled by other base stations, specifically, the flag information of the candidate neighbor cells in the neighbor relation table of the target cell may be used as a keyword to screen the cells controlled by other target base stations and the cells controlled by other base stations, so as to obtain the neighbor cells corresponding to the target cell where the user equipment is located.
In this embodiment, the flag information of the neighboring cell corresponding to the target cell may be used as a keyword, and the current network sensing information of the neighboring cell corresponding to the target cell, from the current network sensing information of the controlled cell sent by other base stations and the current network sensing information of the cell controlled by the target base station sent by the user equipment, is determined as the current network sensing information of the candidate neighboring cell.
In the neighbor cell switching method provided by this embodiment, current network sensing information of a cell controlled by a target base station, which is sent by user equipment, is received, current network sensing information of the controlled cell, which is sent by other base stations in communication connection with the target base station, is received, the cell controlled by the target base station and cells controlled by other base stations in communication connection with the target base station are screened, so as to obtain a neighbor cell corresponding to the target cell where the user equipment is located, and the current network sensing information of the neighbor cell corresponding to the target cell is determined as the current network sensing information of a candidate neighbor cell; because the neighbor cell corresponding to the target cell is screened from the cell controlled by the target base station and the cells controlled by other base stations in communication connection with the target base station, and the current network sensing information of the neighbor cell corresponding to the target cell is determined as the current network sensing information of the candidate neighbor cell, the current network sensing information of the candidate neighbor cell can be accurately and completely determined.
EXAMPLE III
Fig. 5 is a schematic flowchart of a neighboring cell handover method according to a third embodiment of the present application, and as shown in fig. 5, the neighboring cell handover method provided in this embodiment refines step 303 on the basis of any one of the above embodiments, and then the step 303 refinement includes step 501 to step 502.
In this embodiment, the current network awareness information may include each network awareness index and a value of each network awareness index when the user equipment uses the network within a preset evaluation period. Therefore, for the index values capable of directly reflecting the network abnormal situation indexes, such as the access failure rate, the abnormal disconnection rate and the like, the indexes can be directly determined as the network abnormal indexes in the network abnormal situation, and the values of the indexes can be determined as the occurrence rate of the network abnormal indexes in the network abnormal situation. For the indexes which can not directly reflect the abnormal conditions of the network, such as the maximum rate, the bit error rate and the like, the abnormal change of the indexes can be determined as the abnormal indexes of the network, and the occurrence rate of the abnormal change of the indexes in the preset evaluation period can be determined as the occurrence rate of the abnormal indexes of the network. For example, for the rate, the abnormal change of the rate may be determined as the network abnormal index, and the rate of the abnormal change of the rate may be determined as the rate of the network abnormal index. The rate abnormal change may be that the rate of the user equipment after being switched to the candidate neighbor cell is obviously reduced compared with the download rate before being switched, that is: the download rate before switching-the download rate after switching > the threshold of the preset rate deterioration amplitude, and (download rate before switching-download rate after switching)/download rate before switching > the threshold of the preset rate deterioration ratio. The rate of occurrence of abnormal rate change may be a ratio of rate abnormal change occurring after the handover to the candidate neighbor cell to the user equipment handed over to the candidate neighbor cell.
In this embodiment, it can be understood that the less the network abnormal condition is, the better the service performance of the candidate neighbor cell is, and the lower the occurrence rate of the network abnormal condition is, the better the service performance of the candidate neighbor cell is. In this embodiment, specifically, the formula may be usedCalculating the current service performance value of the candidate neighbor cell, wherein Q is the current service performance value of the candidate neighbor cell, RiThe occurrence rate of the ith network abnormal index in the current network abnormal condition of the candidate neighbor cell is represented, and n represents the number of the network abnormal indexes in the current network abnormal condition of the candidate neighbor cell. It can be understood that the maximum value of the service performance value is 1, the minimum value is 0, and if the occurrence rate of any network abnormality index in the network abnormality condition is 100%, the current service performance value of the candidate neighbor cell is0。
In the neighbor cell switching method provided by this embodiment, the current network abnormal situation of the corresponding candidate neighbor cell is determined from each current network sensing information, where the current network abnormal situation includes the occurrence rate of multiple network abnormal indexes, and the current service performance value of the corresponding candidate neighbor cell is calculated according to each network abnormal situation; because the current service performance of the candidate neighbor cell is calculated according to the occurrence rate of each network abnormal index in the network abnormal condition, the service performance value of the candidate neighbor cell with less abnormal condition and lower network abnormal index occurrence rate is larger, the service performance value of the candidate neighbor cell with more abnormal condition and higher network abnormal index occurrence rate is smaller, therefore, the current service performance of the candidate neighbor cell can be quantized into the current service performance value, and the current service performance value of the candidate neighbor cell with better current service performance is higher.
As an optional implementation manner, on the basis of the third embodiment, the step 502 is refined, and then the step 502 refinement includes steps 5021 to 5022.
Step 5021, aiming at each network abnormal condition, the weight corresponding to the occurrence rate of each network abnormal index is obtained.
In this embodiment, the weight corresponding to the occurrence rate of each network anomaly index may be preset. Illustratively, the corresponding weight may be preset to 0.4 when the occurrence rate of access failure is (85%, 100% >), the corresponding weight may be preset to 0.3 when the occurrence rate of access failure is (50%, 85% >), the corresponding weight may be preset to 0.2 when the occurrence rate of access failure is (25%, 50% >), the corresponding weight may be preset to 0.1 when the occurrence rate of access failure is [ 0%, 25% > ].
Step 5022, a weighted average value of the incidence rates of the network abnormal indexes is obtained, and the current service performance value of the corresponding candidate neighbor cell is determined according to the weighted average value.
In this embodiment, the weighted average of the occurrence rates of the network abnormal indicators reflects the network abnormal situation of each candidate neighbor cell, and it can be understood that, the higher the weighted average of the occurrence rates of the network abnormal indicators is, the worse the actual service performance is, and the lower the weighted average of the occurrence rates of the network abnormal indicators is, the better the actual service performance is. Since the weighted average of the occurrence rates of the network abnormal indicators is a number greater than 0, in this embodiment, the reciprocal of the weighted average of the occurrence rates of the network abnormal indicators may be determined as the current service performance value of the corresponding candidate neighbor cell. Here, if the weighted average of the occurrence rates of the respective network abnormality indexes is 0, the current service performance value of the corresponding candidate neighbor may be determined as the maximum value among the current service performance values of all the candidate neighbors. In this embodiment, the current service performance value of the candidate neighboring cell may also be determined by using other methods, which are not limited herein.
In the neighbor cell switching method provided by this embodiment, weights corresponding to the occurrence rates of network abnormal indicators are obtained for each network abnormal condition, a weighted average of the occurrence rates of the network abnormal indicators is obtained, and the weighted average is determined as the current service performance value of the corresponding candidate neighbor cell; the weighted average value of the incidence rate of each network abnormal index is obtained, so that the influence of each network abnormal index on the actual service performance of the candidate neighbor cell is more accurately quantified, and the actual service performance of the candidate neighbor cell can be better reflected according to the current service performance value of the candidate neighbor cell determined by the weighted average value.

Fig. 6 is a schematic flowchart of a neighboring cell handover method according to a fourth embodiment of the present application, and as shown in fig. 6, the neighboring cell handover method provided in this embodiment refines step 304 on the basis of any one of the above embodiments, and step 304 refinement includes step 601 to step 602.
In this embodiment, the current service performance value of the candidate neighbor cell may be corresponding to different current handover condition priorities, and the higher the service performance value is, the higher the corresponding current handover condition priority is. For example, the current service performance values of the candidate neighbor cells may be sorted from large to small, the current handover condition priority corresponding to the current service performance of the first 50% of the candidate neighbor cells (including the middle candidate neighbor cell when the number of the candidate neighbor cells is odd) is determined as a first priority, the current handover condition priority corresponding to the current service performance of the last 50% of the candidate neighbor cells is determined as a second priority, and the first priority is higher than the second priority. In this embodiment, the number of the priorities may be preset according to the number of the candidate neighbor cells.
In this embodiment, the current handover condition related offset value corresponding to the current handover condition of the candidate neighboring cell may be determined to be a value from large to small according to the order of the priorities from high to low. And when the priorities of the current switching conditions are the same, the corresponding related offset values of the current switching conditions are the same.
In the neighbor cell switching method provided in this embodiment, the current switching condition priority corresponding to the current service performance value of each candidate neighbor cell is determined, and the corresponding current switching condition related offset value is determined according to the current switching condition priority of each candidate neighbor cell; the actual service performance of each candidate neighbor cell is converted into the corresponding current switching condition priority, and the actual service performance of each candidate neighbor cell is reflected in a switching condition priority mode, so that when the current service performance values are different, the current service performance values correspond to the same switching condition priority, and the current switching condition related offset values corresponding to the candidate neighbor cells with the same switching condition priority are set to be the same, therefore, the number of the switching condition related offset values can be reduced, and the data volume required to be sent by the base station is further reduced.
As an optional implementation manner, on the basis of the fourth embodiment, the step 601 is refined, and then the step 601 refinement includes steps 6011 to 6012.
Step 6011, matching each current service performance value with a plurality of preset service performance intervals respectively.
In this embodiment, the plurality of preset service performance intervals correspond to different numerical ranges of the current service performance value, and the current service performance value can be respectively matched with the plurality of preset service performance intervals only according to the specific numerical value of the current service performance value.
Step 6012, determining the priority of the current handover condition corresponding to the candidate neighbor according to the preset service performance interval matched with each current service performance value; the boundary value of the preset service performance interval and the current switching condition priority of the corresponding candidate adjacent cell are in positive correlation.
In this embodiment, the correspondence between each preset service performance interval and the current switching condition priority of the candidate neighboring cell may be preset. A preset service performance interval may correspond to a current handover condition priority, and a boundary value of the preset service performance interval may be a maximum value or a minimum value in a numerical range of the preset service performance interval, and is in a positive correlation with the current handover condition priority, that is, a candidate neighboring cell with a larger value of the service performance value has a higher corresponding current handover condition priority.
In the neighboring cell switching method provided in this embodiment, each current service performance value is respectively matched with a plurality of preset service performance intervals, and the current switching condition priority of a corresponding candidate neighboring cell is determined according to the preset service performance interval matched with each current service performance value, where a boundary value of the preset service performance interval and the current switching condition priority of the corresponding candidate neighboring cell are in a positive correlation; the current service performance value of each candidate neighbor cell is respectively matched with a plurality of preset service performance intervals, and the preset service intervals correspond to different current switching condition priorities, so that the current switching condition priority corresponding to the candidate neighbor cells can be determined, the actual service performance of each candidate neighbor cell is reflected by the switching condition priority, and the current switching condition related offset value of each candidate neighbor cell can be adjusted by adjusting the current switching condition priority of each candidate neighbor cell, so that the candidate neighbor cell with better actual service performance has a higher current switching condition related offset value, the candidate neighbor cell with better actual service performance can more easily meet the current switching condition of the target cell, and the user equipment is guided to be switched to the cell with better actual service performance.
As an optional implementation manner, on the basis of the fourth embodiment, the step 602 is refined, and then the step 602 refinement includes the steps 6021 to 6022.
Step 6021, acquiring the pre-stored mapping relationship between the current switching condition priority and the bias value related to the current switching condition.
In this embodiment, the pre-stored mapping relationship between the priority of the current switching condition and the bias value related to the current switching condition may be a preset function, a preset mapping table, and the like, the preset function may be a function in which the priority of the current switching condition is used as an independent variable and the bias value related to the current switching condition is used as a dependent variable, and the preset mapping table may include the priority of the current switching condition and the bias value related to the current switching condition corresponding to each priority of the current switching condition. The pre-stored mapping relation only needs to map the same current switching condition priority to the same current switching condition related offset value. For different current handover condition priorities, different current handover condition related offset values may be mapped, or the same current handover condition related offset value may be mapped. And the current switching condition related offset value is used for indicating the user equipment to acquire the current switching condition of the target cell and the signal strength of each candidate neighbor cell, and determining the target neighbor cell according to the current switching condition, the signal strength of each candidate neighbor cell and the current switching condition related offset value.
And 6022, determining a corresponding current switching condition correlation bias value according to the mapping relation and the current switching condition priority of each candidate neighboring cell, wherein the current switching condition priority and the corresponding current switching condition correlation bias value are in a positive correlation relation.
In this embodiment, the current switching condition related offset value corresponding to the current switching condition priority of the candidate neighbor cell may be queried in the preset mapping table, and the higher the current switching condition priority of the candidate neighbor cell is, the larger the corresponding current switching condition related offset value may be.
In the neighbor cell switching method provided by this embodiment, a mapping relationship between a pre-stored current switching condition priority and a current switching condition related bias value is obtained, and a corresponding current switching condition related bias value is determined according to the mapping relationship and the current switching condition priority of each candidate neighbor cell, where the current switching condition priority and the corresponding current switching condition related bias value are in a positive correlation; the current switching condition related offset value corresponding to each candidate neighbor cell is directly obtained through the pre-stored mapping relation, so that the current switching condition related offset value of each candidate neighbor cell can be quickly determined.
