Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a processing method for excessive coverage provided in an embodiment of the present invention, as shown in fig. 1, the method includes:
step S11, obtaining user soft sampling data, and determining an over-long coverage cell according to the soft sampling data;
specifically, in order to handle the problem of too far coverage, first, user soft data is obtained, where the soft data includes signaling data of a network side related to a user and measurement report data of the user, a cell in which too far coverage occurs may be determined by the signaling data and the measurement report data, and is recorded as a too far coverage cell, and all too far coverage cells are combined into a too far coverage cell list.
Step S12, if judging that the user in the too far coverage cell meets the preset switching-out condition, switching in the user to a corresponding adjacent cell;
specifically, the handover policy in the prior art is based on handover of Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ), and as the RSRP or RSRQ of the serving cell deteriorates, the RSRP or RSRQ of the neighbor cell becomes better, and when a preset threshold is reached, handover from the serving cell to the neighbor cell is triggered. In order to avoid the occurrence of the abnormal event caused by the problem of the too-far coverage, the embodiment of the invention provides a new switching strategy aiming at the problem, a switching-out condition is preset, and when the user of the too-far coverage cell meets the preset switching-out condition, the user is switched into the corresponding adjacent cell in advance, so that the abnormal event caused by the too-far coverage is avoided. In this case, the area where these users are handed over from the too far coverage cell to the neighboring cell forms a handoff island area.
Step S13, adding the too far coverage cell into the cut-out blacklist of the neighboring cell, and prohibiting a user in the neighboring cell from cutting into the too far coverage cell.
Specifically, the too-far coverage cell in the too-far coverage cell list is added into a cut-out blacklist of a corresponding peripheral adjacent cell, and a user of the adjacent cell is forbidden to cut into the too-far coverage cell, so that the too-far coverage cell is added into a switching adjacent cell of the peripheral adjacent cell of the too-far coverage area to be the blacklist, and the peripheral adjacent cell of the cross-area island area is forbidden to cut into the too-far coverage cell, so that abnormal events caused by multiple times of switching of the user in the cross-area island area are avoided.
For example, user soft acquisition data is acquired, an excessively far coverage cell is determined to be a cell a according to the soft acquisition data, then the network side judges whether a user in the cell a meets a preset switching-out condition in real time, if so, the user is switched into a corresponding adjacent cell, if not, the cell switching step is not executed, and then the excessively far coverage cell a is added into a switching-out blacklist of an adjacent cell B and an adjacent cell C, so that the user cannot be switched into the cell a from the cell B or the cell C, and abnormal events caused by the excessively far coverage problem are avoided.
The method for processing the too-far coverage provided by the embodiment of the invention determines the too-far coverage cell according to the user soft acquisition data, sets a new cell switching strategy aiming at the problem of the too-far coverage, switches the user to the corresponding adjacent cell in advance when judging that the user in the too-far coverage cell meets the preset switching-out condition, adds the too-far coverage cell into the switching-out blacklist of the adjacent cell, prohibits the user from switching into the too-far coverage cell from the adjacent cell, effectively reduces the occurrence of abnormal events of the too-far coverage area, and improves the network quality.
On the basis of the foregoing embodiment, further, the acquiring user soft data and determining an excessively far coverage cell according to the soft data includes:
acquiring user soft acquisition data, and determining the frequency of abnormal events of each cell according to the soft acquisition data;
if the frequency is judged to be larger than a preset frequency threshold value, whether the first time lead of the user in the cell and the first reference signal receiving power meet a first preset threshold value is judged according to the soft acquisition data, and if so, the cell is determined to be an over-long coverage cell.
Specifically, obtaining user soft acquisition data, determining the number of times of abnormal events occurring in each cell according to signaling data in the soft acquisition data, for example, abnormal events such as handover failure, dropped call or missing neighboring cells, determining the number of times of abnormal events occurring and the Time point of abnormal events occurring by analyzing the signaling data, if the number of times of abnormal events occurring in a user in a cell is greater than a preset number threshold, indicating that the user in the cell has multiple abnormal events, then determining the Time Advance (TA) of the user having abnormal events occurring in the cell according to the soft acquisition data, the serving cell reference signal receiving power and the neighboring cell reference signal receiving power of the user, the TA being the Time advance for transmitting signals by a terminal UE, the UE receiving a TA command from a network side, adjusting the transmission Time of uplink PUCCH/PUSCH/SRS, in order to eliminate different transmission delays between UEs, the time when the uplink signals of different UE reach the base station eNodeB is aligned, the uplink orthogonality is ensured, and the interference in the cell is reduced. Therefore, the TA represents the distance between the UE and the antenna port of the base station, and the distribution of the terminals can be known by the TA value. The larger the TA value, the farther the user is from the base station. The TA value and the RSRP value can be directly obtained through measurement report data MR in the user soft acquisition data, according to the too-far coverage definition, the actual coverage area of the cell exceeds the planned cell coverage area, and when the TA value is large and both RSRP values are relatively high, the cell is the too-far coverage cell. And carrying out statistical analysis on the variation conditions of the TA and the RSRP values of different cells in which the user resides before and after the abnormal event occurs based on the MR big data to determine a cell list with an over-long coverage problem. For example, when a handover failure event occurs in the cell a for multiple times, the TA value of the user obtained through analyzing the MR data is 7, which is greater than the preset threshold 6, and both RSRP1 and RSRP2 are greater than 100dBm, that is, the user should be handed over to an adjacent cell originally, and due to the too far coverage of the cell a, the serving cell of the user is the cell a, and therefore the cell a is the too far coverage cell.
The processing method of the over-long coverage provided by the embodiment of the invention judges the cell of the over-long coverage based on the reference signal receiving power and the time lead according to the user soft acquisition data, is simpler, quicker and more comprehensive compared with positioning methods such as DT test, customer complaint and the like, sets a new cell switching strategy for the problem of the over-long coverage, switches the user to the corresponding adjacent cell in advance when judging that the user in the over-long coverage cell meets the preset switching-out condition, adds the over-long coverage cell into the switching-out blacklist of the adjacent cell, prohibits the user from switching in from the adjacent cell to the over-long coverage cell, effectively reduces the occurrence of abnormal events of the over-long coverage area, and improves the network quality.
On the basis of the foregoing embodiments, further, the determining that the user in the too-far coverage cell meets a preset handover-out condition includes:
acquiring measurement report data of all users in the too far coverage cell;
determining a second time advance of each user, the second reference signal receiving power of the too-far coverage cell and the third reference signal receiving power of an adjacent cell according to the measurement report data;
if the second time lead is judged and known to be larger than a first preset threshold value and the second reference signal receiving power is larger than a second preset threshold value, determining that the user is an over-long coverage user;
and if the fact that the third reference signal receiving power of the over-long coverage user is larger than a third preset threshold value is judged and obtained, determining that the over-long coverage user meets a preset switching-out condition.
Specifically, measurement report data MR of all users in an excessively far coverage cell is acquired, a time advance of each user is determined through analysis, and is recorded as a second time advance TA2, a serving cell reference signal received power is recorded as a second reference signal received power RSRP2, and a third reference signal received power RSRP3 of an adjacent cell, and then it is determined whether TA2 is greater than a first preset threshold X and RSRP2 is greater than a second preset threshold Y, and if both are greater, it is indicated that the user is an excessively far coverage user. And then, judging whether the RSRP3 of the too-far coverage user is greater than a third threshold value Z, if so, determining that the too-far coverage user meets a preset switching-out condition, and switching the user to an adjacent cell, wherein the third threshold value Z may be set to be the same as the second threshold value Y or greater than the second threshold value.
The method for processing the too-far coverage provided by the embodiment of the invention judges the cell and the user covered by the too-far coverage based on the reference signal receiving power and the time advance according to the user soft acquisition data, sets a new cell switching strategy for the too-far coverage problem, switches the user to the corresponding adjacent cell in advance when judging that the user in the too-far coverage cell meets the preset switching-out condition, adds the too-far coverage cell into the switching-out blacklist of the adjacent cell, prohibits the user from switching into the too-far coverage cell from the adjacent cell, effectively reduces the occurrence of abnormal events of the too-far coverage area, and improves the network quality.
On the basis of the foregoing embodiments, further, the first preset threshold, the second preset threshold, and the third preset threshold are determined according to the following method:
acquiring user soft acquisition data, and determining a third time lead and a fourth reference signal receiving power of a first service cell of each user before an abnormal event occurs according to the soft acquisition data;
determining a fourth time lead and a fifth reference signal receiving power of a second serving cell of each user after an abnormal event occurs according to the soft acquisition data;
determining the first preset threshold according to the third time advance and the fourth time advance;
determining the second preset threshold and the third preset threshold according to the fourth reference signal received power and the fifth reference signal received power.
Specifically, user soft acquisition data is acquired, a time point of an abnormal event occurring to a user is determined through signaling data in the soft acquisition data, time advance and reference signal receiving power of a serving cell before and after the abnormal event occurring to each user are determined according to MR data in the soft acquisition data, for convenience of distinguishing, a serving cell of the user before the abnormal event occurring is recorded as a first serving cell, a serving cell of the user after the abnormal event occurring is recorded as a second serving cell, the time advance of the first serving cell is recorded as a third time advance, the time advance of the second serving cell is recorded as a fourth time advance, the reference signal receiving power of the first serving cell is recorded as a fourth reference signal receiving power, and the reference signal receiving power of the second serving cell is recorded as a fifth reference signal receiving power.
Based on the analysis result of the MR big data, the change conditions of the timing advance TA and the reference signal received power RSRP before and after the occurrence of the abnormal event mainly include the following two conditions: one is that the TA value of the main service cell before the occurrence of the abnormal event of the user in the over-long coverage area is large and the RSRP value is good, the RSRP is rapidly reduced and the TA value is large when the abnormal event occurs, and the TA value of the cell residing after the abnormal event occurs is small and the RSRP value is good; the other is that the TA value of the main service cell is large and the RSRP value is good before the abnormal event of the user occurs in the coverage area which is too far away, the abnormal event occurs for too short time, the RSRP is not rapidly reduced after the MR data is collected, and the TA value of the cell where the abnormal event occurs is small and the RSRP value is good.
Therefore, a first preset threshold may be set according to the time advance before and after the occurrence of the abnormal event, for example, the first preset threshold is set to 6, and a second preset threshold and a third preset threshold may be set according to the serving cell reference signal received power before and after the occurrence of the abnormal event, for example, both set to-100 dBm.
Fig. 2 is a schematic diagram of an excessive coverage scenario provided by an embodiment of the present invention, as shown in fig. 2, a base station a, a base station B, and a base station C all have typical azimuth angles of 0, 120, and 240, each base station includes three cells, which are 1 cell, 2 cells, and 3 cells, respectively, and a direction angle and a downtilt of an antenna are adjusted to a reasonable angle in a previous priority process through survey.
The statistical analysis of the switching failure events through soft acquisition data shows that the switching failure between the cell of the base station A2 and the cell of the base station C3 is frequent and the switching failure times are more. Analyzing RSRP and TA values before and after switching failure based on MR big data to know that a user occupies a 2-cell area of the base station A before switching, the RSRP value fluctuates between-94 dBm and-100 dBm, and the TA value fluctuates between 6 and 7; occasionally, a steep drop problem occurs during switching, and the steep drop is about 15 dB; and after switching, the terminal occupies a 3-cell C base station, and the RSRP value fluctuates between-90 dBm and-101 dBm. The MR data table before and after the occurrence of the switching event is shown in table 1:
TABLE 1 MR data sheet reported by UE
Through the analysis of the table 1, signals meet the conditions that the RSRP is more than or equal to 100dBm and the TA is more than or equal to 6 before the UE user fails in switching, and the TA value is less than or equal to 3 and the RSRP value is more than or equal to 100dBm after switching. Therefore, the first threshold of the timing advance can be set to 6, and the second and third thresholds of the reference signal received power can be set to 100 dBm.
Due to the too far coverage of the a base station 2 cell, a cross-over island problem is formed in the coverage area of the C base station 3 cell. In order to solve the problem of switching failure when a UE user moves between an over-long coverage area of a cell of a base station (A) 2 and a coverage boundary zone of a peripheral adjacent cell, the UE user is moved to a cell of a base station (C) 3 in advance, the cell of the base station (A) 2 is added into a blacklist of the cell of the base station (C) 3, and the user in the cell of the base station (C) 3 is forbidden to be switched to the cell of the base station (A) 2, so that abnormal events caused by over-long coverage can be avoided.
The method for processing the too-far coverage, provided by the embodiment of the invention, is characterized in that a too-far coverage judgment threshold is preset according to a network condition to enable a judgment result to be more accurate, a cell and a user which are covered too far are judged based on reference signal receiving power and time lead according to user soft acquisition data, a new cell switching strategy is set for the problem of the too-far coverage, when the user in the too-far coverage cell is judged to meet a preset switching-out condition, the user is switched to a corresponding adjacent cell in advance, the too-far coverage cell is added into a switching-out blacklist of the adjacent cell, the user is forbidden to switch from the adjacent cell to the too-far coverage cell, the occurrence of abnormal events of the too-far coverage area is effectively reduced, and the network quality is improved.
On the basis of the foregoing embodiments, further, the hand-in of the user to a corresponding neighboring cell includes:
sending a cell switching instruction to the user;
receiving fifth reference signal receiving power of all adjacent cells sent by the user, determining the adjacent cells after switching according to the fifth reference signal receiving power, and switching the user into the adjacent cells.
Specifically, when the network side judges that the user meets the preset switching-out condition, a cell switching instruction is sent to the user, the user sends the reference signal receiving power of all the adjacent cells to the network side and records the reference signal receiving power as fifth reference signal receiving power, and after the network side receives the reference signal receiving power of all the adjacent cells of the user, the network side sorts the reference signal receiving power according to the priority from large to small, and switches the user into the corresponding optimal adjacent cell.
In practical application, the user may also send the reference signal reception quality of all the neighboring cells to the network side, and after receiving the reference signal reception quality of all the neighboring cells of the user, the network side sorts the received reference signal reception quality of all the neighboring cells according to the priority from large to small, and switches the user into the corresponding optimal neighboring cell.
The method for processing the too-far coverage provided by the embodiment of the invention is based on the triggering conditions of the time lead and the reference signal receiving power of the serving cell and the adjacent cell, when the network side monitors that the time lead, the reference signal receiving power and the adjacent cell reference signal receiving power of the cell where the user is located meet the preset switching-out conditions, a switching-out strategy is triggered, the network side sends out a switching-out command to the user in the too-far coverage cell in advance, and the user is moved to the corresponding optimal adjacent cell according to the priority sequence of the reference signal receiving power or the reference signal receiving quality from large to small of the adjacent cell information reported by the user measurement. The method has the advantages that the method adds the over-long coverage cells into the switching neighbor cells of the neighbor cells around the over-long coverage area as the blacklist, prohibits the neighbor cells around the island area of the cross-area from being switched into the over-long coverage cells, makes up for the defect of over-long coverage in the traditional optimization method, avoids abnormal events caused by over-long coverage, and improves network quality.

The switching-out module 32 presets a switching-out condition, and when the user in the cell covered too far meets the preset switching-out condition, switches the user into the corresponding adjacent cell in advance, so as to avoid the occurrence of abnormal events caused by the too far coverage. In this case, the area where these users are handed over from the too far coverage cell to the neighboring cell forms a handoff island area. The processing module 33 adds the too far coverage cell in the too far coverage cell list to the cut-out blacklist of the corresponding neighboring cell, and prohibits the user of the neighboring cell from being cut into the too far coverage cell, so that the too far coverage cell is added to the switching neighboring cell of the too far coverage area as the blacklist, and the neighboring cell of the island area of the cross-area is prohibited from being cut into the too far coverage cell, thereby avoiding the occurrence of abnormal events caused by multiple times of switching of the user in the island area of the cross-area.
