Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows a flowchart of a method for determining a cell coverage scenario provided in this embodiment, where the method includes:
s101, calculating the MR-RSRP coverage rate of the source cell according to the MR-RSRP (Measurement Report-Reference Signal Receiving Power) data reported by each terminal, and determining the coverage type of the source cell according to the MR-RSRP coverage rate of the source cell.
Wherein the MR-RSRP data is an average value of received signal power on all resource elements carrying reference signals, and is a key parameter representing wireless signal strength.
The MR-RSRP coverage of the source cell is the ratio of the MR-RSRP sampling points of the source cell to all RSRP sampling points.
The coverage type of the source cell is determined according to the coverage rate of the source cell, and generally includes three types: a good coverage type, a general coverage type, and a weak coverage type.
S102, MR-RSRP data of a target neighbor cell set of the source cell is obtained, MR-RSRP coverage of the target neighbor cell set is calculated according to the MR-RSRP data of the target neighbor cell set, and the coverage type of the target neighbor cell set is determined according to the MR-RSRP coverage of the target neighbor cell set.
The MR-RSRP coverage of the target neighbor cell set is the ratio of the MR-RSRP sampling points of the target neighbor cell set to all RSRP sampling points.
The coverage type of the target neighbor cell set is determined according to the coverage rate of the target neighbor cell set, and generally includes three types: a good coverage type, a general coverage type, and a weak coverage type.
S103, determining cell coverage scenes under different communication modes according to the coverage type of the source cell and the coverage type of the target adjacent cell set.
Specifically, the method for determining the cell coverage scenario provided by this embodiment is suitable for determining the cell coverage scenario among multiple network systems, such as between 5G and 4G and between 4G and 5G, and between 6G and 5G and between 5G and 6G in future development trend, and can provide a basis for the user residence parameter and improve the user perception.
Taking the existing China mobile network mainstream 4G network TDD and FDD network as an example, MR-RSRP data of TDD and FDD two systems can truly feed back the real coverage condition of a cell, and provide a basis for reasonably setting interoperation parameters of TDD and FDD two systems.
The cell coverage scenario is determined according to the communication system and the coverage type of the source cell and the target neighbor cell set, and includes the communication system of the source cell, the coverage type of the source cell, the communication system of the target neighbor cell set, the coverage type of the target neighbor cell set, a reselection strategy and a handover strategy.
By determining a specific cell coverage scenario, the method can correspond to a specific reselection strategy and a specific handover strategy, and is convenient for the terminal to rapidly handover from the source cell to the target neighbor cell in the target neighbor cell set.
In the embodiment, the MR-RSRP data is used as the basis for processing, so that the support of actual coverage data can be obtained, and the actual coverage condition of each cell can be accurately reflected; and determining the coverage types of each source cell and each adjacent cell through the MR-RSRP data so as to determine cell coverage scenes under different communication modes, and accurately, effectively and comprehensively evaluating the coverage condition of a full amount of users through a specific cell coverage scene.
Further, on the basis of the above method embodiment, S101 specifically includes:
analyzing and obtaining one or more RSRP sampling points corresponding to a source cell according to MR-RSRP data of the source cell reported by each terminal in a first preset time period;
calculating to obtain the MR-RSRP coverage rate of the source cell according to all the RSRP sampling points and one or more RSRP sampling points corresponding to the source cell;
and determining the coverage type of the source cell according to a preset coverage type corresponding rule and the MR-RSRP coverage of the source cell.
Wherein the first preset time period is a preset time period, for example, 7 days.
The RSRP sampling points are preset single points or intervals for sampling the RSRP.
For example, the 4G coverage reports MR-RSRP data to a big data platform through a mobile terminal, and the platform queries through query conditions, field names, and data descriptions shown in the following table one, and analyzes each RSRP sampling point:
table one query specification
The range of the RSRP sampling points is shown in the following table, and the sampling points MR-RSSRP _00 correspond to one interval from-infinity to-120 dBm; an interval from-120 dBm to-115 dBm is set, and the corresponding sampling point RSRP _01 is obtained; every 1dB interval from-115 dBm to-80 dBm corresponds to a sampling point RSRP _02 to a sampling point RSRP _ 36; every 2dB interval from-80 dBm to-60 dBm corresponds to a sampling point RSRP _37 to a sampling point RSRP _ 46; an interval greater than-60 dBm corresponds to sample point RSRP _47, and so on.
Value range of two sampling points in table
In order to guarantee the reliability and stability of the data, the data are taken for 7 days, namely the first preset time period is 7 days. The method comprises the following steps of summarizing and calculating the number of RSRP sampling points of each cell by using MR-RSRP data of cell level and antenna level, and calculating the ratio of RSRP to each level value according to the data, wherein the calculation formula is as follows:
coverage of a certain RSRP ═ 100% greater than MR-RSRP sample points/total MR-RSRP sample points of the RSRP
For example:
coverage of-90 dBm ═ RSRP _28+ RSRP _27+ - - - - + RSRP _47)/(RSRP _00+ RSRP _01+ - - - + RSRP _47) × 100%
The following intervals can be calculated:
-coverage of 75 dBm: sampling point ratio of >;
coverage of 85 dBm: sampling point proportion of-85 dBm;
coverage of 90 dBm: sampling point proportion of-90 dBm;
coverage of-110 dBm: sampling point proportion of-110 dBm;
specifically, according to the analysis and arrangement of MR-RSRP data, combined with the external field test index statistics, the 4G signal is easy to have overlapping coverage increase and SINR deterioration when being less than-90 dBm, resulting in perception deterioration, and therefore-90 dBm is set as a critical point of coverage deterioration.
As shown in fig. 2, according to the sampling ratio of RSRP less than-90 dBm in MR-RSRP, since the data report of MR-RSRP is reported by the terminal, representing the real coverage of the cell, the ratio of RSRP < -90dBm less than 8% is defined as a good coverage cell, the ratio of RSRP < -90dBm between [ 8%, 15% ] is defined as a general coverage cell, the ratio of RSRP < -90dBm greater than 15% is a weak coverage cell, and the cells are defined as three coverage types by differentiating the ratio of RSRP < -90dBm, as shown in the following table:
table three cell coverage type
The MR-RSRP coverage rate of each source cell can be rapidly calculated in a RSRP sampling point mode, and therefore the coverage type of each source cell can be rapidly determined.
Further, on the basis of the above method embodiment, S102 specifically includes:
acquiring MR-RSRP data of a target neighbor cell set of a source cell in a second preset time period from a data acquisition and analysis platform;
carrying out frequency band distinguishing on a target adjacent cell set of a source cell, and acquiring one or more RSRP sampling points corresponding to the target adjacent cell set in a preset number before switching times;
calculating to obtain the MR-RSRP coverage rate of the target neighbor cell set according to all the RSRP sampling points and one or more RSRP sampling points corresponding to the target neighbor cell set;
and determining the coverage type of the target neighbor cell set according to a preset coverage type corresponding rule and the MR-RSRP coverage of the target neighbor cell set.
The second preset time period may be the same as or different from the first preset time period. Generally, the second preset time period is the same as the first preset time period, so that more accurate data can be obtained conveniently.
Specifically, neighbor cell switching data of a source cell and target neighbor cell set pair is derived from an OMC (Operation and Maintenance Center), and 7-day summarized data is obtained for ensuring data accuracy; then, the source cell and the target neighbor cell set are distinguished in frequency band, such as frequency band E \ D \ F of FDD1800 and TDD; selecting TOP N cell switching pairs with more switching times from a source cell and a sub-band target neighbor cell set, wherein N is generally set according to the number of neighbor cells of the current network, and if the set number is too large, the MR-RSRP data of the cell with less switching times has deviation, generally proposing to select 10 neighbor cells; and finally, calculating the MR-RSRP data of the TOP N cell, and summarizing the MR-RSRP data into a sample proportion of MR-RSRP < -90 dBm.
Specifically, since the handover reselection corresponds to all neighboring cells, the neighbor cell MR-RSRP data of the sub-band statistical neighboring cells are summarized and calculated when calculating the neighboring cells, such as FDD1800 and FDD900, and the neighbor cell data may reflect all coverage reflections of the part.
The existing network of China Mobile is the mainstream 4G network TDD and FDD network, and theoretical research and the existing network test statistics show that: when the receiving level is higher than-90 dBm, the service provided by the TDD network can still meet the QoS quality requirement of the user; when the receiving level is less than-90 dBm, the influence perception of the SINR is poor due to the overlapping influence of the RSRP signals of the multiple cells, but at the moment, the FDD network mainly has the advantages of FDD1800 and FDD900 due to the standard advantages of frequency bands and frequency division duplexing, the deep coverage is good, at the moment, the service can be preferentially migrated to the FDD network, and the perception reduction of users is avoided.
It should be noted that, RSRP data of MR-RSRP data of a cell level T days is acquired, and the more T days, the more accurate the data model is, the more T suggested value is 7 days; m days of data are obtained in a gathering way by the adjacent cell, and M is more than or equal to 3 and less than or equal to 7 in M days; more TOP N switching times are selected for each frequency band to serve as an effective data source of a neighbor cell, and the value of N is set according to the network size, for example, 10 neighbor cells can be selected in an urban area, 4 values can be selected in a rural area, and the actual condition is needed.
The embodiment can flexibly set parameters and avoid the problem that the perception is influenced by the poor RSRP receiving of the edge user.
It should be noted that the determination process and effect of the MR-RSRP coverage and coverage type of the neighbor cell are the same as the determination process and effect of the MR-RSRP coverage and coverage type of the source cell, and are not described herein again.

Specifically, by respectively defining three defined coverage scenarios of TDD \ FDD, each scenario of TDD corresponds to each scenario of FDD, and there are 18 scenarios in total, as shown in fig. 2, the following table four is specifically classified:
reselection strategy and handover strategy for table four-cell coverage scenarios
In this embodiment, coverage types of cells under different network standards are defined according to MR-RSRP data, and a cell coverage scenario is determined according to different types of cell coverage, which is convenient for determining a handover reselection strategy between a source cell and an adjacent cell and formulating a reasonable handover reselection threshold according to the cell coverage scenario.
Further, on the basis of the above method embodiment, the method for determining a cell coverage scenario further includes:
reselecting a target neighbor cell in the target neighbor cell set from the current source cell according to a reselection strategy;
and controlling the terminal to be switched from the source cell to the target neighbor cell according to the switching strategy.
Specifically, cell reselection is divided into three phases: obtaining reselection parameters, starting testing of the adjacent cells and judging cell reselection. The neighbor cell test is mainly divided into the following three types:
first, low- > high (reselection priority): the UE always performs measurements on these high priority cells;
second, same priority/same frequency: the serving cell is less than or equal to the serving cell threshold (co-frequency)/non-co-frequency measurement threshold (inter-frequency), and the UE performs measurement lower than the non-measurement;
third, high- > low (reselection priority): the RSRP value of the serving cell is smaller than or equal to a non-co-frequency measurement threshold, measurement is executed, and the RSRP value is larger than the non-measurement threshold;
the cell reselection decision mainly has the following criteria: if a plurality of adjacent cells on the highest priority meet the conditions, selecting the optimal cell on the highest priority frequency, and adopting the R criterion of the same-frequency cell reselection for the same-priority frequency points (or the same frequency).
The cell reselection of the high-priority frequency point needs to meet the following conditions:
the time for the UE to reside in the source cell exceeds 1 s;
the S value of the high priority frequency cell is greater than the high priority reselection threshold value and the duration exceeds the reselection time parameter T.
The cell reselection of frequency points with the same frequency or priority needs to meet the following conditions:
the time for the UE to reside in the source cell exceeds 1 s;
and the R criterion is continuously met in the same-frequency or same-priority cell T time.
The cell reselection of the low-priority frequency point needs to meet the following conditions:
the time that the UE resides in the source cell exceeds 1 s;
the RSRP value of the service cell is smaller than the service frequency point threshold, and the RSRP value of the adjacent cell is larger than the low-priority reselection threshold.
Specifically, the reselection-related parameters are shown in the following table five:
table five-reselection correlation parameter description
In addition, the handover in the E-UTRAN (UMTS Terrestrial Radio Access Network ) in the connected mode is a handover controlled by the terminal auxiliary Network, and the handover process is divided into three parts: measurement, decision and execution. For the handover in the LTE system, the handover mainly includes intra-station handover and inter-station handover:
the intra-site handover comprises the steps of:
s1, the eNodeB configures the measurement of the UE and sends the measurement control information to the UE through the RRC reconfiguration message. The UE performs measurement configuration at an RRC protocol end of the UE according to measurement control issued by the eNode B, and sends an RRC Connection Reconfiguration Complete message to the eNode B to indicate that the measurement configuration is completed;
s2, UE reports measurement report to eNode B according to measurement configuration, including information of service cell and adjacent cell;
s3, the eNode B makes a decision of UE handover based on the measurement report and the radio resource management information. When the eNode B considers that the switching is necessary, a proper target neighbor cell is determined, and the access control of the target neighbor cell is requested;
s4, the target adjacent cell carries out resource admittance, and air interface resources and SAE bearing resources of service are distributed for UE access;
s5, the source cell sends the parameters needed by the UE to access the target adjacent cell during the switching execution to the UE to execute the switching through the RRC Connection Reconfiguration information;
s6, completing uplink synchronization with the target adjacent cell;
s7, after receiving the RRC reconfiguration message containing MobilityControlInfo, the UE interrupts the radio connection with the source cell and starts to establish a new radio connection with the target neighboring cell, and during this time, the data transmission is interrupted. When the UE is successfully accessed to the target adjacent cell, the UE sends RRC connection reconfiguration completion information to the target adjacent cell to indicate that the switching process is completed for the UE.
The inter-station switching comprises the following steps:
b1, source eNode B configures UE measurement and sends measurement control information to UE through RRC reconfiguration message. The UE performs measurement configuration at an RRC protocol end of the UE according to measurement control issued by the eNodeB, and sends an RRC connection reconfiguration Complete message to the eNode B to indicate that the measurement configuration is completed;
b2, UE reports the measurement report to eNode B according to the measurement configuration. The source eNode B makes a decision for UE handover based on the measurement report and radio resource management information. When the source eNode B considers that the switching is necessary, a proper target neighbor cell is determined, and the source eNode B controlling the target neighbor cell is requested to be accessed;
b3, in order to reserve resources for Handover at the target side, the source eNodeB sends Handover Request information to the target eNodeB and transmits necessary information. The target adjacent cell carries out resource access and allocates air interface resources and SAE bearing resources of services for the access of the UE;
b4, after the target neighbor cell resource is successfully admitted, sending a Handover Request acknowledgement message to the source eNodeB to inform the source eNB of preparing resources in the target eNB;
b5, eNodeB sends the parameters needed by UE accessing the target adjacent cell to UE through RRC Connection Reconfiguration message when switching;
b6, the message is sent to the target eNB by the source eNB and is used for sending the PDCP SN and HFN state of the uplink/downlink E-RAB in the switching process;
b7, completing uplink synchronization with the target neighbor cell;
b8, after receiving the RRC reconfiguration message containing MobilityControlInfo, the UE interrupts the radio connection with the source eNode B and starts to establish a new radio connection with the target eNode B, during which time the data transmission is interrupted. When the UE is successfully accessed to the target neighbor cell, the UE sends RRC connection reconfiguration complete information to the target eNode B to indicate that the switching process is completed for the UE.
