It can be understood that, in the embodiment of the present invention, the user equipment is first subjected to the neighbor cell determination to determine one or more neighbor cells (in this embodiment, the first neighbor cell) that meet the access requirement of the current user equipment, then, the first adjacent cells are screened according to the switching failure times of each first adjacent cell, the first adjacent cells which do not meet the requirements are added into a blacklist, then, the updated blacklist list is sent to the user equipment, so that when the user equipment performs neighbor cell measurement to complete LTE switching, the neighbor cells located in the blacklist are not measured and corresponding measurement data is not uploaded to the base station, meanwhile, the neighbor cells in the blacklist do not need to be measured and a measurement report is uploaded to the base station, therefore, the bandwidth load of the network side is reduced, the power consumption of the user equipment and the system signaling overhead are reduced, and the success rate of system switching can be greatly improved. Meanwhile, the dynamic blacklist mechanism is intelligently set, the step that the traditional means needs to observe the blacklist for a long time and manually increase the blacklist is reduced, and the timeliness is better.
The following describes in detail a specific technical solution of the LTE handover optimization method provided in this embodiment with reference to fig. 1 again.
First, step S01 is executed: and judging the adjacent cells of the user equipment so as to determine at least one first adjacent cell which meets the current access requirement of the user equipment in the adjacent cells of a service cell (also called a main service cell) where the user equipment is currently located.
Optionally, in the embodiment of the present invention, a decision period may be preset, a neighboring cell decision is performed on the user equipment every other decision period, and/or when the user equipment needs to perform LTE handover, the base station is triggered to perform the neighboring cell decision on the user equipment, which is not limited in this regard.
It should be appreciated that LTE handover may be base station triggered or user equipment triggered. Taking the triggering of the ue as an example, when the ue moves, due to changes in location and the like, parameters between the ue and the serving cell where the ue is located may reach a measurement report threshold, for example, the power is low, and the execution of the service cannot be supported, so that in order to ensure normal operation of the service, the ue may measure each neighboring cell, and generate a measurement report according to a measurement result.
Before LTE handover, a base station needs to obtain a measurement report of a user equipment and load information of a neighboring cell, and selects a neighboring cell (a first neighboring cell in an embodiment of the present invention) meeting a current access requirement from neighboring cells of a serving cell where the user equipment is currently located according to the measurement report of the user equipment and the load information of the neighboring cell.
In one or more embodiments of the invention, step S01: the method for determining a neighboring cell of a serving cell in which the user equipment is currently located to determine at least one first neighboring cell that meets a current access requirement of the user equipment includes:
step S011: obtaining a Measurement Report (MR) of the user equipment, wherein the Measurement Report comprises a reference signal received power of at least one fourth neighboring cell in a current serving cell and all neighboring cells of the serving cell of the user equipment, and the fourth neighboring cell is a neighboring cell which is not in a blacklist list in all neighboring cells of the serving cell.
Specifically, in the LTE system, when the ue moves and a measurement report reporting threshold is reached, the ue may report a measurement report to the base station, and the base station may receive the measurement report uploaded by the ue. Of course, there may be other reasons that the base station may receive the measurement report uploaded by the user equipment, which is not limited in this application.
It should be noted that the measurement report uploaded by the user equipment does not necessarily include reference signal received power and load information of all neighboring cells corresponding to the user equipment, in the embodiment of the present invention, the user equipment may screen the neighboring cells according to a blacklist, measure the neighboring cells not in the blacklist and upload a corresponding measurement report, and in order to facilitate the differentiation, the present invention names the neighboring cell not in the blacklist of the user equipment as a fourth neighboring cell.
The blacklist is established and dynamically updated by the base station, the updated blacklist is sent to the user equipment in real time, and each user equipment has a corresponding blacklist.
It can be understood that the blacklist is set as one of the improvement points of the present invention, when the user equipment performs the neighbor cell measurement to complete the LTE handover, the user equipment can exclude the neighbor cell located in the blacklist from being measured and upload the corresponding measurement data to the base station according to the blacklist, thereby improving the handover success rate, reducing the measurement report data of the neighbor cell in the blacklist, and reducing the load of the bandwidth of the network side.
The neighboring cell is a cell adjacent to the cell where the user equipment is located. Specifically, each base station may have a neighboring cell relationship table, where each cell in the base station and a neighboring cell of each cell are stored in the neighboring cell relationship table. Since the neighbor relation table is a prior art, it is not discussed in detail in this application.
For example, the cell in which the ue a is located is cell 1, and the cell 1 is adjacent to the cell 2 and the cell 3 in geographic locations, then the cell 2 and the cell 3 are adjacent to the cell 1, that is, the cell 2 and the cell 3 are adjacent to the ue a, and the base station includes the cell 2 in a blacklist that is issued at the nearest time from the current time, then the ue a measures the cell 3, and correspondingly, the uploaded measurement report includes RSRP (reference signal received power) of the cell 3.
For example, the measurement report uploaded by the ue includes the following fields:
step S012: and acquiring load information of the service cell and each fourth neighboring cell.
In order to achieve the purpose of load balancing during cell switching, the base station needs to acquire load information of a serving cell where the user equipment is located and each fourth neighboring cell, in addition to the RSRP of the serving cell and the neighboring cells of the user equipment. The load information may include, but is not limited to, the number, traffic volume, and/or resource utilization of the ue in the serving cell and each neighboring cell.
When the base station acquires the load information of the fourth neighboring cell, the base station can directly acquire the load information of the fourth neighboring cell of the user equipment, which belongs to the base station, and for the fourth neighboring cell of the user equipment, which does not belong to the base station, the base station can acquire the load information of the fourth neighboring cell by interacting with the base station where the fourth neighboring cell is located. Therefore, the load information of each fourth neighboring cell can be obtained, and load balancing is facilitated.
Step S013: and determining at least one first adjacent cell which meets the current access requirement of the user equipment in the at least one second adjacent cell according to the reference signal receiving power and the load information of the serving cell and the at least one fourth adjacent cell.
Specifically, when performing cell handover, the reason that the user equipment needs to perform cell handover needs to be considered, for example, when performing cell handover due to the reason that the RSRP of the current serving cell of the user equipment does not meet the requirement and/or the load backlog, and the like, the RSRP and the load information of each fourth neighboring cell need to be integrated, for example, different weights are allocated according to the handover reason to determine which neighboring cells can be finally selected as target cells during handover, that is, the first neighboring cell in the embodiment of the present invention.
Next, step S02 is executed: and judging whether each first adjacent cell meets a preset condition or not according to the switching failure times of each first adjacent cell in at least one first adjacent cell in a preset statistical range, and adding the first adjacent cells which do not meet the preset condition into a blacklist.
Further, in order to improve the handover success rate, the embodiment of the present invention further implements a filtering mechanism for the first neighboring cell obtained after the base station performs the neighboring cell decision.
Referring to fig. 2, optionally, step S02: according to the number of switching failures of each first neighboring cell in the at least one first neighboring cell within a preset statistical range, judging whether each first neighboring cell meets a preset condition, and adding the first neighboring cells which do not meet the preset condition into a blacklist, which may specifically include:
step S021: determining the first switching failure times of each first adjacent cell in a first time period T1, judging whether a second adjacent cell with the first switching failure times exceeding a first threshold value N exists in at least one first adjacent cell, and if so, adding the second adjacent cell into a low-priority list.
Step S022: and determining the second switching failure times of each second adjacent cell in a second time period T2, judging whether a third adjacent cell with the second switching failure times exceeding a second threshold value M exists in the second adjacent cells, and if so, adding the third adjacent cell into a blacklist list.
It should be noted that the number of failed handover times means the number of times of unsuccessful handover in at least one handover of the second neighboring cell performed by the ue within the preset statistical range. Specifically, a target cell is determined from neighboring cells of a user equipment according to data such as a measurement report and then switched to the target cell, but unavoidable factors or faults and the like also cause a situation of switching failure in the target cell determined according to the measurement report.
For convenience of distinguishing, in the embodiment of the present invention, the number of handover failures of each first neighboring cell in the first time period is named as a first number of handover failures, and the number of handover failures of each second neighboring cell in the second time period is named as a second number of handover failures.
In other embodiments, the preset statistical range is not limited to be determined according to time, and may also be determined according to the number of times that the user equipment attempts to switch to the second neighboring cell/the third neighboring cell, for example, according to the number of times that each first neighboring cell/the second neighboring cell fails to switch in X times (for example, 100 times) of switching that is closest to the current time, to determine whether to add the second neighboring cell/the third neighboring cell to the low priority list/the blacklist.
It is further required to know that, after the base station determines the third neighboring cell exceeding the second threshold M and adds the third neighboring cell to the blacklist, the third neighboring cell in the second neighboring cell is deleted from the low priority list, so that the neighboring cells in the low priority list and the blacklist do not overlap.
In the embodiment of the present invention, the ending times of the first time period T1 and the second time period T2 are both current times, the duration corresponding to the first time period T1 is greater than the duration corresponding to the second time period T2, the ratio of the duration corresponding to the first threshold N and the first time period T1 is greater than the ratio of the duration corresponding to the second threshold M and the second time period T2, that is, N/T1 > M/T2.
Further, if at least one first handover failure frequency does not exceed the first threshold and there is no fifth neighboring cell located in the low priority list in the at least one first neighboring cell, the target cell is determined in the at least one fifth neighboring cell, and a handover instruction for handover to the target cell is sent to the user equipment.
Further, if there is no second neighboring cell in the at least one first neighboring cell whose first handover failure number exceeds the first threshold, the target cell is determined in the at least one first neighboring cell. The method for determining the target cell in the at least one first neighboring cell may be random, or the method may further include ranking the at least one first neighboring cell according to the measurement report and the load information, selecting the first neighboring cell for handover from high to low according to a ranking result, and ending the procedure if the handover is successful.
It can be understood that the invention ensures the call quality, the channel utilization efficiency and the system switching success rate by setting the low priority list, setting the low priority neighbor cell for the first time and dynamically judging the blacklist neighbor cell mechanism for the second time.
Further, after the third neighboring cell is added to the blacklist, the method further includes: and if the time length of the second adjacent region in the low priority list reaches the preset first time length, removing the second adjacent region from the low priority list.
Further, after the third neighboring cell is added to the blacklist, the method further includes: if the time length of the third adjacent cell in the blacklist reaches the preset second time length, removing the third adjacent cell from the blacklist; and sending the updated blacklist to the user equipment.
It is to be noted that the first duration and the second duration are punished durations, and when the time reaches a preset time, the base station automatically moves out the corresponding neighboring cells from the low priority list and the blacklist list, so that the corresponding neighboring cells enter a normal switching process, user perception can be better guaranteed, and user experience is improved.
