To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The method for determining the neighboring base station provided by the present application may be applied to the application environment shown in fig. 1. The base station management station 101 is in communication connection with each base station 102 in the control area, and is configured to monitor and manage the base stations 102. The base station management station 101 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, a method for determining a neighboring base station is provided, where the method may be implemented in a base station management station 101, and includes:
step S100, acquiring attribution information and report business data of each base station in a control area;
wherein, the attribution information indicates the position attribute of the base station, and the report service data reflects various service conditions currently operated by the base station.
Specifically, the process of acquiring the attribution information and the report service data may be that each base station in the management and control area actively reports the attribution information and the report service data of itself at regular intervals, or that the base station management station 101 sends a data request to each base station in the management and control area, so that each base station reports the attribution information and the report service data of itself to the base station management station 101.
Step S200, dividing each base station in the control area into a plurality of adjacent area groups according to the attribution information of each base station;
specifically, the key factor for determining whether a base station can be set as a neighboring base station of another base station is that the cells of two base stations must be connectable, so to determine the neighboring base station of each base station, division is performed from the position of each base station first. The attribution information can indicate the position attribute of the base station, all base stations in the control area are firstly divided into a plurality of adjacent area groups according to the attribution information, the base stations are firstly divided on the position attribute, each base station is possible to determine the adjacent area relation only with other base stations in the adjacent area groups, and the efficiency of determining the adjacent area base stations of each base station in the control area is improved.
Step S300, according to the attribution information and report business data of each base station, for any base station, in the adjacent cell group to which the base station belongs, the adjacent cell base station of the base station is determined.
Specifically, for each neighboring cell group, the neighboring cell base station of each base station in the group is selected from the base stations of the neighboring cell group by considering the base stations in the group from two aspects of position attributes and various service conditions according to the attribution information and report service data of the base stations in the group.
In the method for determining a neighboring base station provided in the above embodiment, according to the attribution information of each base station in the management and control area, each base station is first divided into different neighboring groups, and in each neighboring group, the neighboring base station of each base station in the group is determined according to the report service data and the attribution information of each base station in the group. Based on the method, the adjacent cell relation between the base stations is judged according to the attribution information and the report service data reported by the base stations in real time, the attribution information and the report service data can reflect the position attribute and various service conditions of the base stations more comprehensively, the service switching success rate of the determined adjacent cell base stations is higher, the smoothness during switching is better, and the call drop rate of the cell edge of each base station is lower. In addition, the embodiment directly obtains the data required by determining the neighboring base station from the base station, and does not need the participation of the user terminal, thereby reducing the burden of the communication system and lowering the complexity of the method.
In an embodiment, as shown in fig. 3, the process of determining, for any one of the base stations, a neighboring base station of the base station in the neighboring group to which the base station belongs according to the attribution information of each base station and the report service data includes:
step S310, for any adjacent cell group, calculating the adjacent cell relation parameter of each adjacent cell candidate base station to a reference base station according to the attribution information and report service data of each base station in the adjacent cell group, wherein the reference base station is any base station in the adjacent cell group, and the adjacent cell candidate base station is any base station except the reference base station in the adjacent cell group;
step S320, determining the neighboring cell base station of each reference base station in each neighboring cell group according to the neighboring cell relation parameter of each neighboring cell candidate base station in each neighboring cell group to the reference base station.
The neighbor relation parameter is used for indicating the degree of the neighbor relation of the neighbor candidate base station relative to the reference base station, that is, the association degree of the neighbor candidate base station and the reference base station.
Specifically, after each base station in the control area is divided into a plurality of neighboring cell groups, the neighboring cell groups are used as a unit to calculate the neighboring cell base station of each base station in each neighboring cell group. In any adjacent area group, the following steps are carried out for any base station: the base station is used as a reference base station, namely a service switching-out base station during service switching, other base stations in the adjacent cell group are used as adjacent cell candidate base stations, namely candidate service switching-in base stations, the adjacent cell relation degree, namely the adjacent cell relation parameter, of each adjacent cell candidate base station relative to the reference base station is calculated according to the previously obtained attribution information and report service data of each base station, and then the adjacent cell base station of the reference base station is determined according to the adjacent cell relation parameter of each adjacent cell candidate base station. And when the neighbor cell base station of each reference base station in each neighbor cell group is obtained, the neighbor cell base station of each base station in the control area is determined. And calculating the neighbor relation parameters for evaluating the neighbor relation based on the attribution information of each base station and the report service data, so that each base station is more matched with the neighbor base station in actual position distribution and service conditions, and service switching between the neighbors is more stable.
It should be noted that, because the same steps are performed for each base station in each neighboring cell group, each neighboring cell group can be sequentially traversed, then each base station is traversed in the neighboring cell group, each base station is taken as a reference base station in turn, the neighboring cell relation parameters of the reference base station calculated by each neighboring cell candidate base station in the current round are calculated, and the neighboring cell base station of the reference base station calculated in the current round is determined according to the neighboring cell relation parameters; the same calculation procedure for each base station in each neighboring group may be divided into multiple threads to perform calculation simultaneously.
In one embodiment, as shown in fig. 4, the report service data includes a cut-in success rate, a cut-out success rate, a call drop rate, and a packet loss rate. The home information includes location information and area information.
The process of calculating the neighbor relation parameters of the candidate neighbor base stations to the reference base station according to the attribution information and the report service data of each base station in the neighbor group comprises the following steps:
step S311, respectively obtaining distance relation data between each adjacent cell candidate base station and the reference base station according to the attribution information of each adjacent cell candidate base station and the attribution information of the reference base station;
the location information indicates the location of the base station, and may include latitude and longitude positioning information. The area information indicates an area where the reference is located, the area being defined in advance according to a mobile communication network plan.
Specifically, the location information includes latitude and longitude positioning information of the base station. For any one adjacent cell candidate base station, the distance between the adjacent cell candidate base station and the reference base station is calculated according to the attribution information of the adjacent cell candidate base station and the reference base station, but the distance is converted into distance relation data according to a certain preset rule because the distance is weighted and calculated together with report service data.
Step S312, performing weighted operation on the cut-in success rate of each neighboring candidate base station, the cut-out success rate of each neighboring candidate base station, the drop call rate of each neighboring candidate base station, the packet loss rate of each neighboring candidate base station, and the distance relation data between each neighboring candidate base station and the reference base station, to obtain neighboring relation parameters of each neighboring candidate base station to the reference base station, respectively.
The switching-in success rate is the success rate of switching the service from other base stations to the base station, and the switching-out success rate is the success rate of switching the service from the base station to other base stations.
Specifically, for any one neighboring cell candidate base station, the cut-in success rate, the cut-out success rate, the call drop rate, the packet loss rate of the neighboring cell candidate base station and the distance relation data of the neighboring cell candidate base station and the reference base station are weighted and added by corresponding preset weights, so as to obtain the neighboring cell relation parameter of the neighboring cell candidate base station to the reference base station. The preset weight is a corresponding weight preset for each item of data according to operation and maintenance experience.
The calculation process can be represented by the following formula,
wherein, CanrRepresenting the neighbor relation parameter, and the value range is from 0 to 100. XiI is 1,2, and 3 … 5 respectively represent the cut-in success rate, the cut-out success rate, the call drop rate, the packet loss rate, and the distance relation data, and the range of values is 0 to 1. WiI is 1,2,3 … 5 and XiI is a preset weight corresponding to 1,2,3 … 5, and ranges from 0 to 100
It should be noted that the report service data may also include other data besides the above-mentioned four data according to the actual application requirements.
In an embodiment, as shown in fig. 4, the process of determining the neighboring cell base station of each reference base station in each neighboring cell group according to the neighboring cell relation parameter of each neighboring cell candidate base station in each neighboring cell group to the reference base station includes:
step S321, for any reference base station in any neighbor cell group, selecting a plurality of neighbor cell candidate base stations with neighbor cell relation parameters larger than the neighbor cell threshold value as a plurality of neighbor cell base stations of the reference base station.
The neighbor cell threshold is a preset numerical value and is used for judging whether a neighbor cell relation parameter of a neighbor cell candidate base station to a reference base station reaches a neighbor cell base station which can be used as the reference base station. If the neighbor relation parameter of any neighbor candidate base station to the reference base station is greater than the neighbor threshold, the degree of the neighbor relation of the neighbor pre-selection base station relative to the reference base station reaches the standard, and the neighbor candidate base station is determined to be the neighbor base station of the reference base station.
Specifically, for any reference base station in any neighbor cell group, the process of calculating the neighbor cell relation parameter of each neighbor cell candidate base station to the reference base station is independent, so that after the neighbor cell relation parameter of each neighbor cell candidate base station to the reference base station is obtained, a plurality of neighbor cell candidate base stations with the neighbor cell relation parameter larger than the neighbor cell threshold value are selected to be determined as a plurality of neighbor cell base stations of the reference base station; or after obtaining the neighboring cell relation parameter of the neighboring cell candidate base station to the reference base station, comparing the neighboring cell relation parameter with a neighboring cell threshold to determine whether the neighboring cell candidate base station can be used as the neighboring cell base station of the reference base station, and if the neighboring cell relation parameter is greater than the neighboring cell threshold, determining that the neighboring cell candidate base station is the neighboring cell base station of the reference base station.
However, in the practical application process, the inventor finds that some base stations in some neighboring cell groups are built at the central position, and when they are used as reference base stations, almost all other base stations can be used as their neighboring cell base stations, so that the accuracy requirement of the algorithm for performing service handover in the reference base station is higher, and the time required for service handover is longer. Therefore, in an embodiment, as shown in fig. 5, after selecting a plurality of neighboring cell candidate base stations whose neighboring cell relation parameters are greater than the neighboring cell threshold, the method further includes:
step S322, if the number of the selected neighbor cell candidate base stations is greater than N, selecting N neighbor cell candidate base stations with the largest neighbor cell relation parameter from the selected neighbor cell candidate base stations as N neighbor cell base stations of the reference base station; n is a positive integer.
Specifically, the step of selecting the N neighboring cell candidate base stations with the largest neighboring cell relation parameter may be to sort the neighboring cell candidate base stations with the neighboring cell relation parameter larger than the neighboring cell threshold value from large to small, and select the first N neighboring cell candidate base stations as the neighboring cell base stations of the reference base station in the sorting result. The upper limit of the number of the adjacent base stations is set to be N, the adjacent base stations of the reference base station are limited within a certain number, and the stable operation of service switching among the base stations is guaranteed.
In an embodiment, as shown in fig. 6, after determining the neighboring cell base station of each base station in each neighboring cell group according to the attribution information of each base station and the report service data, the method further includes:
and step S400, sending the neighboring cell relation information to the corresponding base stations in the neighboring cell groups, wherein the neighboring cell relation information is used for representing the neighboring cell base station corresponding to any base station in any neighboring cell group.
Specifically, the corresponding neighbor relation information is sent to each base station in the controlled area, so that each base station knows its corresponding neighbor base station, and thus, a neighbor relation list of itself is established. One piece of neighbor relation information corresponds to one base station, and can represent the corresponding relation between the base station and the neighbor base station. In one embodiment, cell identification information of the base station and its corresponding neighboring base station may be included, and the identification information may include PCI and ECGI of the cell.
In an embodiment, as shown in fig. 7, the process of sending the neighboring cell relation information to each corresponding base station in each neighboring cell group includes:
step S410, acquiring the operation mode of a reference base station for any reference base station in any adjacent cell group;
step S420, if the reference base station is in the free mode, sending corresponding adjacent area relation information to the reference base station;
step S430, if the reference base station is in the controlled mode, displaying the neighboring base station corresponding to the reference base station, and after receiving the confirmation instruction, sending corresponding neighboring relationship information to the reference base station.
Specifically, if one reference base station is in the controlled mode, the neighboring base station of the reference base station is displayed to the network administrator of the base station management and control station, and the network administrator can send a confirmation instruction or a cancellation instruction through the input device. And after receiving the confirmation instruction of the network management personnel, sending corresponding adjacent region relation information to the reference base station. When the reference base station is in the controlled mode, the neighbor relation information is sent to the reference base station only through manual confirmation, and the safety of the system is improved.
The process of displaying the neighboring base station of the reference base station to the network manager of the base station management and control station may be to generate a neighboring relation record of the reference base station according to a corresponding relationship between the reference base station and the neighboring base station, and display the neighboring relation record to the network manager. The display to the network management personnel can be displayed by a screen, and the input instruction of the network management personnel can be finished by input equipment such as a touch screen, a mouse, a keyboard and the like.
In one embodiment, if the reference base station is in the free mode, the process of sending the corresponding neighboring cell relation information to the reference base station includes:
if the reference base station is in the free mode, after one adjacent base station of the reference base station is determined, the effectiveness judgment is carried out on the adjacent base station;
and after the adjacent base station is judged to be the effective base station, sending corresponding adjacent relation information to the reference base station.
