Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method for handling 4 / 5G interoperability problems, an apparatus for handling 4 / 5G interoperability problems, an electronic device, and a computer-readable storage medium. Background Technology

[0002] Currently, 5G network deployment primarily utilizes a 1:1 co-location approach with 4G sites. However, 5G networks operate at higher frequencies than 4G networks, resulting in smaller coverage areas. In areas with sparse 5G site distribution, there is often 4G coverage but no or weak 5G coverage. Furthermore, most suburban areas, towns, and rural areas lack 5G coverage and rely on 4G networks as their basic coverage infrastructure. When a terminal moves at the edge of 5G coverage where 4G coverage exists, 4G / 5G interoperability is involved. Therefore, proper configuration of 4G / 5G interoperability parameters is crucial to ensure the continuity of voice and data services, reduce ping-pong handovers (or redirections) and reselections between different systems, minimize frequent TAU ​​(Tracking Area Update) and re-registration, thereby reducing service interruption latency and improving user experience speeds.

[0003] However, the existing 4G / 5G interoperability threshold parameter strategies are not uniform, and are even disjointed. For example, for cells with good 5G coverage, the difficulty of migrating to 4G is increased; conversely, for cells with poor 5G coverage, the difficulty of migrating to 4G is reduced. The same considerations apply to the migration from 4G to 5G. During network changes and user model changes, policy modifications are inconsistent, often resulting in surrounding sites or related parameters not being modified synchronously. This leads to problems such as inter-system ping-pong handover, late start testing, insufficient measurement intervals, or unnecessary TAUs (Transient Acceptance Units). Summary of the Invention

[0004] This invention provides a method, apparatus, electronic device, and computer-readable storage medium for handling 4 / 5G interoperability issues, in order to solve or partially solve the problem of communication risks caused by logical errors in operating parameters during the 4 / 5G network handover process.

The union of the first 4 / 5G neighbor cell pair and the second 4 / 5G neighbor cell pair is taken to obtain the target 4 / 5G neighbor cell pair table.

Then, the LTE neighbor cell relationships are associated with the 4G cell attribute information to generate a first 4 / 5G neighbor cell pair table. The NR neighbor cell relationships are associated with the 5G cell attribute information to generate a second 4 / 5G neighbor cell pair table. Finally, the union of the first and second 4 / 5G neighbor cell pairs is taken to obtain the target 4 / 5G... The system uses a neighbor cell pairing table, and then checks the target 4 / 5G neighbor cell pairing table for ping-pong handover issues based on the access network interoperability parameters and the new air interface interoperability parameters. It outputs a set of 4 / 5G interoperability issues corresponding to the target region. By acquiring relevant communication data and configuring parameters based on this data, the system can verify issues involved in the 4 / 5G interoperability process. This effectively solves problems such as inter-system ping-pong handover, late start-up testing, insufficient measurement intervals, or unnecessary TAUs. It facilitates the investigation of logical errors in operational parameters during the 4 / 5G network handover process. Furthermore, based on the output issue set, it can not only effectively verify existing problems for timely resolution, but also eliminates the need for on-site testing and signaling analysis, reducing reliance on the experience of relevant personnel and improving the applicability of the scenario.

[0102] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0103] As an example, current 5G network deployment primarily utilizes a 1:1 co-location approach with 4G sites. However, 5G network frequencies are higher than 4G frequencies, resulting in a smaller coverage area. In areas with sparse 5G site distribution, there is often 4G coverage but no or weak 5G coverage. Furthermore, most suburban areas, towns, and rural areas lack 5G coverage and require 4G networks as a basic coverage network. When a terminal moves at the edge of 5G coverage where there is 4G coverage, 4G / 5G interoperability is involved. Therefore, it is essential to properly configure 4G / 5G interoperability parameters to ensure the continuity of voice and data services, reduce ping-pong handovers (or redirections) and reselections between different systems, minimize frequent TAUs and re-registrations, thereby reducing service interruption latency and improving user experience speed.

[0104] However, the existing 4G / 5G interoperability threshold parameter strategies are not uniform, and are even disjointed. For example, for cells with good 5G coverage, the difficulty of migrating to 4G is increased; conversely, for cells with poor 5G coverage, the difficulty of migrating to 4G is reduced. The same considerations apply to the migration from 4G to 5G. During network changes and user model changes, policy modifications are inconsistent, often resulting in surrounding sites or related parameters not being modified synchronously. This leads to problems such as inter-system ping-pong handover, late start testing, insufficient measurement intervals, or unnecessary TAUs (Transient Acceptance Units).

[0105] Therefore, verifying interoperability parameter issues between different communication modes is crucial. Traditional interoperability parameter optimization methods generally rely on past ping-pong handover problems, analyzing indicators or signaling to adjust parameters for related sites. This requires significant manpower and time, depends heavily on the experience of network optimization engineers, and cannot prevent problems from occurring in the first place or avoid them across the entire network. Alternatively, methods may independently match and verify the thresholds of each interoperability parameter across the entire network within a certain range, without considering the correlation between different parameters, lacking targeted analysis of logical problems between related parameters, and the set range may not meet the needs of certain special scenarios. Further confirmation and troubleshooting by network optimization personnel familiar with the current network situation are required.

[0106] Because there are millions or even tens of millions of parameters at the neighbor cell pair level in the current network, and this number is still increasing, traditional data processing capabilities are insufficient to conduct network-wide neighbor cell pair parameter verification. With the development trend of big data in recent years, parameter verification has also benefited from big data processing. In view of this, one of the core inventive points of this invention is to consider the correlation between different parameters of different 4G and 5G sites, and propose a method and device for automatic correlation verification of logical problems in 4G / 5G interoperability parameters from the perspectives of avoiding ping-pong handover or redirection, frequent reselection, no measurement gap, and unnecessary TAU. Specifically, by acquiring communication data corresponding to each communication cell in the target area, including 4G and 5G cells, the communication data includes at least LTE neighbor cell relationships of 5G cells, NR neighbor cell relationships of 4G cells, 4G cell attribute information, 5G cell attribute information corresponding to 5G cells, access network interoperability parameters of 5G cells, and new radio interface interoperability parameters of 4G cells. Then, the LTE neighbor cell relationships are associated with the 4G cell attribute information to generate a first 4 / 5G neighbor cell pair table, and the NR neighbor cell relationships are associated with the 5G cell attribute information to generate a second 4 / 5G neighbor cell pair table. The union of the first and second 4 / 5G neighbor cell pairs is then taken to obtain the target 4 / 5G neighbor cell pair table. Finally, based on the... The access network interoperability parameters and the new air interface interoperability parameters are used to check the target 4 / 5G neighbor cell pair table for ping-pong handover issues. A set of 4 / 5G interoperability issues corresponding to the target region is output. By acquiring relevant communication data and configuring parameters based on this data, issues involved in the 4 / 5G interoperability process can be checked. This effectively solves problems such as inter-system ping-pong handover, late start-up testing, insufficient measurement intervals, or unnecessary TAUs. It facilitates the investigation of logical errors in operational parameters during the 4 / 5G network handover process. Furthermore, based on the output issue set, not only can existing problems be effectively identified for timely resolution, but on-site testing and signaling analysis are also eliminated, reducing reliance on the experience of relevant personnel and improving the applicability of the scenario.

[0107] Reference Figure 1 The diagram illustrates a flowchart of a method for handling 4 / 5G interoperability issues provided in an embodiment of the present invention, which may specifically include the following steps:

[0108] Step 101: Obtain communication data corresponding to each communication cell in the target area. The communication cells include 4G cells and 5G cells. The communication data includes at least the LTE (Long Term Evolution) neighbor cell relationship of the 5G cell, the NR (New Radio) neighbor cell relationship of the 4G cell, the attribute information of the 4G cell, the attribute information of the 5G cell corresponding to the 5G cell, the access network interoperability parameters of the 5G cell, and the NR interoperability parameters of the 4G cell.

[0109] In practical implementation, the automatic verification of 4 / 5G interoperability parameter logic problems can be carried out in a hierarchical manner according to the corresponding regions. For example, the verification can be carried out according to the urban area division. When it is necessary to verify the 4 / 5G interoperability parameter logic problems of a certain region, the communication data corresponding to each communication cell in the target region can be collected periodically.

[0110] The communication cell can include 4G cells and 5G cells. Communication parameters can include at least the LTE neighbor cell relationships of the 5G cell, the NR neighbor cell relationships of the 4G cell, 4G cell attribute information, the corresponding 5G cell attribute information, the access network interoperability parameters of the 5G cell, and the new radio interface interoperability parameters of the 4G cell. For the 4G cell attribute information, it can be the basic parameters corresponding to the 4G cell, such as cell identifier, cell frequency band, cell location, etc. Similarly, the 5G cell attribute information can be the basic parameters corresponding to the 5G cell. In the process of 4G / 5G network deployment, for a 4G cell, its neighboring cells can be 5G cells. Based on the 4G cell and the 5G cell, corresponding neighbor cell relationships can be constructed. The relationships corresponding to the 4G cell can be NR neighbor cell relationships, and the relationships corresponding to the 5G cell can be LTE neighbor cell relationships. This invention does not impose any limitations on this.

[0111] Furthermore, the access network interoperability parameters for 5G cells can be shown in Table 1 below:

[0112]

[0113]

[0114] Table 1

[0115] CDUP can be a custom parameter group, representing the cell DU parameters; LCCUP can be a custom parameter group, representing the logical cell CU parameters.

[0116] The new air interface interoperability parameters for 4G cells are shown in Table 2 below:

[0117]

[0118]

[0119] Table 2

[0120] Step 102: Associate the LTE neighbor cell relationship with the 4G cell attribute information to generate a first 4 / 5G neighbor cell pair table; associate the NR neighbor cell relationship with the 5G cell attribute information to generate a second 4 / 5G neighbor cell pair table; and take the union of the first 4 / 5G neighbor cell pair and the second 4 / 5G neighbor cell pair to obtain the target 4 / 5G neighbor cell pair table.

[0121] In the specific implementation, during the verification of logical issues related to 4G / 5G interoperability parameters, neighbor cell pair matching is performed to output corresponding neighbor cell pairs for 4G and 5G. This allows the parameters of 4G and 5G cells with neighbor relationships to be associated for verification. The association method can be one or more methods, such as neighbor cell handover pair indicators, neighbor cell relationship configuration, or a combination of MR and engineering parameters. Considering that neighbor cell handover pair indicators cannot be automatically collected and engineering parameters may be inaccurate, and that 5G fallback to 4G both use handover methods with relatively complete neighbor cell configurations, this embodiment of the invention uses a 4 / 5G bidirectional neighbor cell relationship configuration method to output the corresponding neighbor cell pairs.

[0122] The 4G cell attribute information includes at least the first 5G base station identifier, the first 5G cell identifier, the first 4G base station identifier, and the first 4G local base station identifier. The 5G cell attribute information includes at least the second 5G base station identifier, the second 5G cell identifier, the second 4G base station identifier, and the second 4G local base station identifier. Then, the first 5G base station identifier, the first 5G cell identifier, the first 4G base station identifier, and the first 4G local base station identifier can be associated with the LTE neighbor cell relationship and deduplicated to generate a first 4 / 5G neighbor cell pair table. Then, the second 5G base station identifier, the second 5G cell identifier, the second 4G base station identifier, and the second 4G local base station identifier can be associated with the LTE neighbor cell relationship and deduplicated to generate a second 4 / 5G neighbor cell pair table. Finally, the union of the first 4 / 5G neighbor cell pair and the second 4 / 5G neighbor cell pair is taken to obtain the target 4 / 5G neighbor cell pair table.

[0123] In one example, based on the information of NrNRelationship and the 4G cell itself, each NR neighbor cell data of each 4G cell can be associated with the 4G cell itself into multiple records, including fields such as gNodeBId, 5G_cell_id, eNodeBId, and 4G_Local_Cell_Id. Then, records with identical fields are deduplicated and denoted as NrLtePairA. At the same time, based on the information of LTECellRelation and the 5G cell itself, each LTE neighbor cell data of each 5G cell can be associated with the 5G cell itself into multiple records, also including the four fields from step A, and deduplicated in the same way, denoted as NrLtePairB. Then, the union of NrLtePairA and NrLtePairB is taken and denoted as NrLtePair. The number of records is denoted as n.

[0124] Furthermore, since the connection-mode interoperability parameters are configured separately for QCI, and 4G-related parameters are associated with QCI through parameter groups, the 4G-side parameters need to be decomposed. Specifically, the handover threshold parameter table corresponding to the 4G cell and the inter-system handover common parameter table can be extracted from the new air interface interoperability parameters. The handover threshold parameter table should at least include the first local cell identifier, QCI parameters, NRHOParamGroupId, and InterRatHoCommGroupId. The inter-system handover common parameter table should at least include the inter-system handover A1 RSRP (Reference Signal Receiving Power) threshold, the inter-system handover A2 RSRP threshold, the inter-system handover A1A2 RSRP threshold, the coverage-based E-UTRAN handover to NR B1 event RSRP trigger threshold CovBasedNrB1RsrpThld, and the service-based E-UTRAN (UMTS Terrestrial Radio Access Network) handover to NR The B1 event RSRP trigger threshold ServBasedNrB1RsrpThld and the inter-system handover to new air interface parameter NrB1B2Hysteresis are then used to generate a first target table. Next, the first 4G base station identifier corresponding to the 4G cell is associated with the first local cell identifier, QCI parameters, NRHOParamGroupId, and InterRatHoCommGroupId to obtain a first target table. Using the first local cell identifier and InterRatHoCommGroupId as the primary key, the inter-system handover A1 RSRP threshold, inter-system handover A2 RSRP threshold, and inter-system handover A1A2 RSRP threshold are associated to generate a second target table. Finally, using the first local cell identifier and NRHOParamGroupId as the primary key, CovBasedNrB1RsrpThld, ServBasedNrB1RsrpThld, and NrB1B2Hysteresis are associated to generate a 4G bearer table.

[0125] In one example, the eNodeBId (base station identifier) ​​of each 4G cell can be taken and compared with the LOCALCELLID (local cell identifier) ​​and QCI (QoS Class) of the CELLQCIPARA table (handover threshold parameter table). Table a is created by using the fields Identifier (scale value), NRHOPARAMGROUPID, and InterRatHoCommGroupId as primary keys. Then, using LOCALCELLID and InterRatHoCommGroupId as primary keys, the three fields InterRatHoNrA1ThldRsrp, InterRatHoNrA2ThldRsrp, and InterRatHoA1A2Hyst from the INTERRATHOCOMMGROUP (inter-system handover common parameter table) are linked to obtain table b. Finally, using LOCALCELLID and NRHOPARAMGROUPID as primary keys, the three fields CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld from the INTERRATHONRPARAMGRP (4G bearer table) are linked to obtain table 4G_QCI_PARAM (4G bearer table).

[0126] Step 103: Based on the access network interoperability parameters and the new air interface interoperability parameters, check the target 4 / 5G neighbor cell pair table for ping-pong handover issues, and output the 4 / 5G interoperability issue set corresponding to the target region.

[0127] In this embodiment of the invention, the verification of 4 / 5G interoperability parameter logic issues can be performed by checking for ping-pong handover (or redirection) issues (i.e., the B1 threshold of L2NR must be greater than the B2_1 threshold of NR2L, otherwise ping-pong handover exists). L2NR refers to a terminal moving from an LTE site to an NR site, while NR2L refers to a terminal moving from an NR site to an LTE site. Connected-state mobility includes handover and redirection. Handover includes handover decision, preparation, and execution. Execution is completed through an RRC reconfiguration message, which indicates the target cell information and requires precise configuration of neighboring cells and frequencies. Redirection includes measurement-based redirection and blind redirection. This invention mainly refers to measurement-based redirection, which includes redirection measurement and execution. Execution is completed through an RRC release message, which indicates the target frequency information. Only the frequency points and a corresponding virtual neighbor cell need to be configured. L2NR generally uses service-based handover or redirection, employing the B1 event, which refers to the situation where the measured level of the target cell meets (is higher than) the B1 threshold condition. When the signal level of the serving cell meets (is lower than) the A2 threshold and remains so for a period of time, a handover or redirection to the target cell or frequency point is triggered. NR2L generally uses coverage-based handover or redirection, employing the B2 event. When the measured level of the serving cell meets (is lower than) the A2 threshold and remains so for a period of time, the A2 event is triggered, and the B2 measurement is initiated. When the measured level of the serving cell meets (is lower than) the B2_1 threshold and the measured level of the target cell meets (is higher than) the B2_2 threshold and remains so for a period of time, the B2 event is reported, triggering a handover or redirection. If the B2 event condition is not met but the measured level of the serving cell meets (is higher than) the A1 threshold and remains so for a period of time, the A1 event is reported, the B2 event monitoring is deleted, and the B2 measurement is canceled. The ping-pong effect refers to the terminal switching (or redirecting) back and forth between two base stations.

[0128] In the specific implementation, the target 4 / 5G neighbor cell pair table can be traversed. For the i-th 4 / 5G neighbor cell pair in the target 4 / 5G neighbor cell pair table, the target 5G base station identifier, target 5G cell identifier, target 4G base station identifier, and target 4G cell identifier of the i-th 4 / 5G neighbor cell pair are obtained. Then, from the preset 5G spectrum table, the B2 event association QCI, B2 event trigger threshold 1, B2 event trigger hysteresis value, A2 event association QCI, A2 event trigger threshold, and A2 event trigger hysteresis value that are the same as the target 5G base station identifier and target 5G cell identifier are obtained. At the same time, from the 4G bearer table, the QCI, CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBas that are the same as the target 4G base station identifier and target 4G cell identifier are obtained. Then, for the B2 event associated QCI, B2 event trigger threshold 1, B2 event trigger hysteresis value, A1 event associated QCI, A1 event trigger threshold, and A1 event trigger hysteresis value, an outer join is performed using the B2 event associated QCI and A2 event associated QCI. For QCI, CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld, an inner join is performed using QCI. This generates several target QCI data sets that exist for both access network interoperability parameters and new air interface interoperability parameters. Then, based on these target QCI data sets, a ping-pong handover problem check is performed on the target 4 / 5G neighbor cell pair table, and a set of 4 / 5G interoperability problems corresponding to the target region is output.

[0129] Specifically, by traversing several target QCI data records, for each target QCI data record, compare the records with the same QCI. If (ServBasedNrB1RsrpThld + 0.5 * NrB1B2Hysteresis) - min(B2 event trigger threshold 1 - B2 event trigger hysteresis value - 156, A2 interface average threshold - A2 interface average hysteresis value - 156) < the first preset threshold, output the service-based ping-pong problem set ServBasedPingPongSet_i. At the same time, when traversing several target QCI data records, for each target QCI data record, also compare the records with the same QCI. If (CovBasedNrB1RsrpThld + 0.5 * NrB1B2Hysteresis) - min(B2 event trigger threshold 1 - B2 event trigger hysteresis value - 156, A2 event trigger threshold - A2 event trigger hysteresis value - 156) < the second preset threshold, output the coverage-based ping-pong problem set CovBasedPingPongSet_i. Then take the union between ServBasedPingPongSet_i and CovBasedPingPongSet_i to obtain the connected-state ping-pong problem set PingPongSet_i.

[0130] In specific implementation, it is also possible to use the 5G base station identifier, 5G cell identifier, A1 event associated QCI, A2 event associated QCI, and B2 event associated QCI in the access network interoperability data as the primary key to associate and generate a 5G bearer table with the same QCI. The 5G bearer table includes several 5G QCI data records. Then traverse the fifth-generation (5G) bearer table. For each 5G QCI data record, compare the records with the same 5G base station identifier, 5G cell identifier, and QCI. If (A1 event trigger threshold + A1 event trigger hysteresis value s) - (A2 event trigger threshold - A2 event trigger hysteresis value) < the third preset threshold, output the measurement interval too small problem set 5G_A1A2Set; if A2 event trigger threshold - A2 event trigger hysteresis value < B2 event trigger threshold 1 - B2 event trigger hysteresis value, output the start measurement too late problem set 5G_A2B2Set.

[0131] In specific implementation, the 4G bearer table includes several 4G QCI data records. Then it is also possible to traverse the 4G bearer table. For each 4G QCI data record, compare the records with the same QCI. If InterRatHoNrA1ThldRsrp - InterRatHoNrA2ThldRsrp < the fourth preset threshold, output the start measurement too late problem set 4G_A1A2Set on the 4G side.

[0132] In specific implementation, the minimum received level and low-priority serving cell RSRP decision threshold that are the same as the target 5G base station identifier and target 5G cell identifier can also be obtained from the 5G spectrum table, as well as the minimum received level and NR frequency high-priority reselection threshold that are the same as the target 4G base station identifier and target 4G cell identifier. If (minimum received level + NR frequency high-priority reselection threshold) - (lowest received level of cell + low-priority serving cell RSRP decision threshold) < fifth preset threshold, then the ping-pong reselection problem ReselPingPongSet_i is output, the verification and analysis process of the i-th 4 / 5G neighbor cell pair ends, and this step is repeated to perform the verification and analysis of the next i-th 4 / 5G neighbor cell pair until all 4 / 5G neighbor cell pairs have been verified, and the ping-pong reselection problem set ReselPingPongSet is output. Additionally, the inter-frequency neighbor cell measurement threshold and the low-priority serving cell RSRP decision threshold can be obtained from the 5G spectrum table. If the inter-frequency neighbor cell measurement threshold - the low-priority serving cell RSRP decision threshold ≤ 0, the problem set 5G_ReselMeasSet for late reselection testing is output.

[0133] In specific implementations, the new radio interoperability parameters include the cell reselection frequency priority within the LTE system, and the access network interoperability parameters include the cell reselection frequency priority within the NR system and the sub-priority of the cell reselection frequency point within the NR system. Therefore, the verification of logical issues related to the 4 / 5 interoperability parameters can also include: For the 4G side, if there exists a cell reselection frequency priority within the LTE system that is greater than the sum of the cell reselection frequency priority within the NR system and the sub-priority of the cell reselection frequency point within the NR system, then the 4G side inter-system reselection priority problem set 4G_ReselPriSet is output. Simultaneously, for the 5G side, the access network interoperability parameters include the cell reselection priority, the priority during reselection judgment, and the sub-priority during reselection judgment. If there exists a cell reselection priority that is less than the priority during reselection judgment and the sub-priority during reselection judgment, then the 5G side inter-system reselection priority problem set 5G_ReselPriSet is output.

[0134] In addition, 5G cells include CU cells and DU cells. Therefore, the verification of 4 / 5 interoperability parameter logic issues can also include: extracting the cell DU parameters corresponding to the DU cell and the logical cell CU parameters corresponding to the CU cell from the 5G bearer table. The cell DU parameters include the minimum access level, and the logical cell CU parameters include the low-priority serving cell RSRP decision threshold. If the minimum access level of the DU cell + the low-priority serving cell RSRP decision threshold of the CU cell < min(CU cell B2 event trigger threshold 1 - B2 event trigger hysteresis value - 156, CU cell A2 event trigger threshold - A2 event trigger hysteresis value - 156), then output the QCI level connected state and idle state contradiction problem set 5G_RSHOSet.

[0135] Among them, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, and the fifth preset threshold can be thresholds set according to the corresponding scenarios, and the present invention does not limit them.

[0136] It should be noted that the embodiments of the present invention include, but are not limited to, the examples described above. It is understood that those skilled in the art can make further settings according to actual needs under the guidance of the ideas in the embodiments of the present invention, and the present invention does not limit such settings.

[0137] In this embodiment of the invention, for the 4 / 5G ping-pong handover process, communication data corresponding to each communication cell in the target area can be obtained. The communication cells include 4G cells and 5G cells. The communication data includes at least the LTE neighbor cell relationships of the 5G cells, the NR neighbor cell relationships of the 4G cells, 4G cell attribute information, 5G cell attribute information corresponding to the 5G cells, access network interoperability parameters of the 5G cells, and new radio interface interoperability parameters of the 4G cells. Then, the LTE neighbor cell relationships are associated with the 4G cell attribute information to generate a first 4 / 5G neighbor cell pair table. The NR neighbor cell relationships are associated with the 5G cell attribute information to generate a second 4 / 5G neighbor cell pair table. Finally, the union of the first and second 4 / 5G neighbor cell pairs is taken to obtain the target 4 / 5G... The system uses a neighbor cell pairing table, and then checks the target 4 / 5G neighbor cell pairing table for ping-pong handover issues based on the access network interoperability parameters and the new air interface interoperability parameters. It outputs a set of 4 / 5G interoperability issues corresponding to the target region. By acquiring relevant communication data and configuring parameters based on this data, the system can verify issues involved in the 4 / 5G interoperability process. This effectively solves problems such as inter-system ping-pong handover, late start-up testing, insufficient measurement intervals, or unnecessary TAUs. It facilitates the investigation of logical errors in operational parameters during the 4 / 5G network handover process. Furthermore, based on the output issue set, it can not only effectively verify existing problems for timely resolution, but also eliminates the need for on-site testing and signaling analysis, reducing reliance on the experience of relevant personnel and improving the applicability of the scenario.

[0138] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, an example is provided below for illustration:

[0139] Step 1: Regular data collection: Collect the LTE neighbor cell relationship (LTECellRelation) of all manufacturers' 5G cells and the NR neighbor cell relationship (NrNRelationship) of 4G cells at 0:00 and 12:00 every day for the target user's available sites; in addition, collect the NR interoperability related parameters of 4G cells and the EUTRAN interoperability related parameters of 5G cells.

[0140] Step 2: Neighbor Cell Pair Matching: Output 4G and 5G neighbor cell pairs to associate the parameters of 4G and 5G cells with neighbor cell relationships for verification. The association method can be one or more methods such as neighbor cell handover pair indicators or neighbor cell relationship configuration. Considering that neighbor cell handover pair indicators cannot be automatically collected and that operating parameters may be inaccurate, and that both 5G fallback and 4G use handover methods with relatively complete neighbor cell configurations, this invention uses a 4 / 5G bidirectional neighbor cell relationship configuration method to output neighbor cell pairs. This method specifically consists of the following sub-steps:

[0141] Step A: Based on the information of NrNRelationship and the 4G cell itself, associate each NR neighbor cell data of each 4G cell with the 4G cell itself into multiple records, including fields such as gNodeBId (i.e., 5G base station identifier), 5G_Cell_Id (i.e., 5G cell identifier), eNodeBId (i.e., 4G base station identifier), and 4G_Local_Cell_Id (i.e., 4G cell identifier). Then, remove duplicate records where all the above fields are the same, and denot them as NrLtePairA.

[0142] Step B: Based on the information of LTECellRelation and the 5G cell itself, associate each LTE neighbor cell data of each 5G cell with the 5G cell itself into multiple records, which also contain the 4 fields of Step A and are deduplicated in the same way, denoted as NrLtePairB.

[0143] Step C: Take the union of NrLtePairA and NrLtePairB, denoted as NrLtePair (i.e., the target 4 / 5G neighbor cell pair list), and denote the number of records as n;

[0144] Step 3: Data Preprocessing: Since the connection-mode interoperability parameters are distinct from the QCI configuration, and the 4G-related parameters are associated with the QCI through parameter groups, the 4G-side parameters need to be decomposed. This method is specifically divided into the following sub-steps:

[0145] Step D: Take the eNodeBId of each 4G cell and the LOCALCELLID, QCI, NRHOPARAMGROUPID, and InterRatHoCommGroupId fields of the CELLQCIPARA table to form table a;

[0146] Step E: Using LOCALCELLID and InterRatHoCommGroupId as primary keys, join the three fields InterRatHoNrA1ThldRsrp, InterRatHoNrA2ThldRsrp, and InterRatHoA1A2Hyst of the INTERRATHOCOMMGROUP table to obtain table b;

[0147] Step F: Using LOCALCELLID and NRHOPARAMGROUPID as primary keys, join the three fields CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld of the INTERRATHONRPARAMGRP table to obtain the table 4G_QCI_PARAM.

[0148] Step 4: Check for ping-pong switching (redirection) issues: B1 of L2NR must be greater than the B2_1 threshold of NR2L; otherwise, ping-pong switching exists. This method is specifically divided into the following sub-steps:

[0149] L2NR refers to a terminal moving from an LTE site to an NR site, while NR2L refers to a terminal moving from an NR site to an LTE site. Connected-state mobility includes handover and redirection. Handover involves handover decision, preparation, and execution, with execution completed via RRC reconfiguration messages. These messages indicate target cell information and require precise configuration of neighboring cells and frequencies. Redirection includes measurement-based redirection and blind redirection. This invention primarily refers to measurement-based redirection, which includes redirection measurement and execution. Execution is completed via RRC release messages, indicating target frequency information. Only frequency points and corresponding virtual neighbor cells need to be configured. L2NR generally uses service-based handover or redirection, employing B1 events, which occur when the measured level of the target cell meets (or exceeds) the B1 threshold condition and remains unchanged. After a certain period of time, a handover or redirection to the target cell or frequency is triggered. NR2L generally uses coverage-based handover or redirection, employing the B2 event. When the measured level of the serving cell meets (is lower than) the A2 threshold and persists for a certain period, the A2 event is triggered, initiating the B2 measurement. When the measured level of the serving cell meets (is lower than) the B2_1 threshold, and the measured level of the target cell meets (is higher than) the B2_2 threshold and persists for a certain period, the B2 event is reported, triggering a handover or redirection. If the B2 event condition is not met, but the measured level of the serving cell meets (is higher than) the A1 threshold and persists for a certain period, the A1 event is reported, the B2 event monitoring is deleted, and the B2 measurement is canceled. The ping-pong effect refers to the terminal switching (or redirecting) back and forth between two base stations.

[0150] Step G: Traverse the NrLtePair neighbor pair table. For the i-th neighbor pair (i is the NrLtePair number, i = 1, 2, ..., n), take the gNodeBId and 5G_Cell_Id of NrLtePair_i. Then, take the B2_interrat_coverage_QCI, B2_interrat_coverage_threshold1, B2_interrat_coverage_hysteresis, and 5G_Cell_Id from the 5GLCCUP table that have the same gNodeBId and 5G_Cell_Id. l_Id, A2_interfreq_coverage_QCI, A2_interfreq_coverage_threshold, A2_interfreq_coverage_hysteresis, then take the QCI, CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld from the 4G_QCI_PARAM table where both eNodeBId and 4G_Local_Cell_Id are the same as those in NrLtePair_i;

[0151] Step H: Take the three data sets of NrLtePair_i above, and perform an outer join of the first two 5G data sets using B2_interrat_coverage_QCI and A2_interfreq_coverage_QCI, and then perform an inner join of the QCI of 4G_QCI_PARAM to obtain q data sets NrLtePair_i_QCIPARAM containing both 5G and 4G data. Generally, q = 9.

[0152] Step I: Traverse NrLtePair_i_QCIPARAM. For each piece of data, compare the records with the same QCI. If there exists (4G side ServBasedNrB1RsrpThld + 0.5 * NrB1B2Hysteresis) - min(5G side B2_interrat_coverage_threshold1 - B2_interrat_coverage_hysteresis - 156, 5G side A2_interfreq_coverage_threshold - A2_interfreq_coverage_hysteresis - 156) < x (unit: dB, x is a positive number, and this invention recommends x = 2), then output the service-based ping-pong problem set ServBasedPingPongSet_i; the meaning analysis of this formula is as follows: When moving from 4G in the connected state to 5G, generally the service-based method is used, that is, when 5G is greater than the B1 threshold, it will switch or redirect to 5G. There are two strategies for 5G to fall back to 4G, namely B1 and B2. If B1 is adopted, then B2_interrat_coverage_threshold1 is empty, and when the 5G side threshold is lower than its starting measurement threshold A2, it may fall back to 4G (because the 4G coverage is good and B1 is easily satisfied). If the B1 threshold from 4G to 5G is less than the A2 threshold or too close, then it is very likely to immediately switch or redirect to 5G, forming a dead loop in this process, resulting in discontinuous network data and seriously affecting the user experience; similarly, if the B2 strategy is adopted for 5G to fall back to 4G, when the 5G side threshold is lower than its starting measurement threshold A_{2}, it will measure both the 4G and 5G thresholds simultaneously. When the 5G threshold is lower than B2_1, it may fall back to 4G. Normally, A2 > B2_1 should hold, but there are also configurations in the existing network where A2 <= B2_1, that is, a fallback condition is already satisfied when the measurement is initiated (similarly, the B2_2 threshold is easily satisfied). Therefore, the smaller value between A2 and B2_1 should be taken to judge the fallback condition on the 5G side; in addition, the formula calculates the actually effective threshold value for 4 / 5G interworking, and the same applies hereinafter;

[0153] Step J: Traverse NrLtePair_i_QCIPARAM again (i.e., several QCI data entries). For each data entry, compare it with the records of the same QCI. If (4G-side CovBasedNrB1RsrpThld + 0.5 * NrB1B2Hysteresis) - min(5G-side B2_interrat_coverage_threshold1 - B2_interrat_coverage_hysteresis - 156, A2_interrat_coverage_threshold - A2_interrat_coverage_hysteresis - 156) < x (unit: dB, x is a positive number, and in this invention, x = 2 is recommended), then output the coverage-based ping-pong problem set CovBasedPingPongSet_i. This formula is different from Step I, considering the possible 4G->5G handover or redirection strategy based on coverage on the 4G side and using the 4G-side coverage-based B1 threshold for calculation.

[0154] Step K: Take the union of ServBasedPingPongSet_i and CovBasedPingPongSet_i to obtain the connected-state ping-pong problem set PingPongSet_i, end the verification and analysis process of the i-th NrLtePair, i = i + 1, and continue to repeat the fourth step to perform the verification and analysis of the next i-th NrLtePair until i > n ends. <OOO0328>Step 5: Verify the problem of too late start of measurement: A2 should be greater than B2_1, otherwise it may cause the problem that the signal fades too fast and drops back to 4G before there is time to measure. At the same time, the start measurement threshold A2 should be lower than the stop measurement threshold A1 by a certain interval, otherwise there will not be enough space for inter-system measurement. This verification method is specifically divided into the following sub-steps:

[0156] It should be noted that there is a misspelling in the original text where "OOO0328" should probably be "

[0155] ". This has been corrected in the translation.Step L: Using the gNodeBId, 5G_Cell_Id, A1_interrat_coverage_QCI, A2_interrat_coverage_QCI, and B2_interrat_coverage_QCI of 5G data as the primary keys, associate records with the same QCI to obtain 5G_QCI_PARAM (i.e., the 5G bearer table). The number of records is m. Traverse 5G_QCI_PARAM. For each piece of data, compare records with the same gNodeBId, 5G_Cell_Id, and QCI. If ((A1_interrat_coverage_threshold + A1_interrat_coverage_hysteresis) - (A2_interrat_coverage_threshold - A2_interrat_coverage_hysteresis)) < x (unit: dB, x is a positive number, this invention recommends x = 2), then output the problem set 5G_A1A2Set with too small measurement intervals;

[0157] Step M: Traverse 5G_QCI_PARAM to check if there exists (A2_interrat_coverage_threshold - A2_interrat_coverage_hysteresis) < (B2_interrat_coverage_threshold1 - B2_interrat_coverage_hysteresis). If it exists, then output the problem set 5G_A2B2Set with too late start of measurement;

[0158] Step N: Traverse the 4G_QCI_PARAM table. For each piece of data, compare records with the same QCI. If InterRatHoNrA1ThldRsrp - InterRatHoNrA2ThldRsrp < x (unit: dB, x is a positive number, this invention recommends x = 2), then output the problem set 4G_A1A2Set with too late start of measurement on the 4G side;

[0159] Sixth step: Check the idle state 4 / 5G mobility problem (heterogeneous system idle state mobility moves to the target cell by means of reselection). This method is specifically divided into the following sub-steps:

[0160] For the inter-frequency reselection start threshold, it means that when the serving cell is lower than this threshold, the inter-frequency and inter-system reselection measurement is started; the low-priority reselection threshold of the serving cell means that when the serving cell has a higher priority than the target cell, such as moving from 5G to 4G, if the UE stays on the current serving cell for more than 1 second, the measured level of the serving cell is lower than this threshold, and during TreselectionEUTRA, the threshold of the target cell is higher than the EUTRAN low-priority reselection threshold, then it will reselect to the target cell;

[0161] Step O: Verify the ping-pong reselection problem, that is, the reselection threshold of L2NR needs to be greater than the low-priority reselection threshold of the serving cell of NR2L, otherwise there is ping-pong: Traverse the NrLtePair table of neighbor cell pairs. For the i-th neighbor cell pair (i is the number of NrLtePair, i = 1, 2,..., n), take the gNodeBId and 5G_Cell_Id of NrLtePair_i, and respectively take the Qrxlevmin and Threshservinglowp with the same gNodeBId and 5G_Cell_Id in the 5GCDUP table. Then take the MinRxLevel and NrFreqHighPriReselThld of the NRNFREQ with the same eNodeBId and 4G_Local_Cell_Id as in NrLtePair_i. If there is (4G side NRNFREQ.MinRxLevel + NRNFREQ.NrFreqHighPriReselThld) - (5G side CDUP.Qrxlevmin + LCCUP.Threshservinglowp) < x (unit: 2dB, x is a positive number, this invention recommends x = 1), then output the ping-pong reselection problem ReselPingPongSet_i, end the verification and analysis process of the i-th NrLtePair, i = i + 1, continue to repeat this step to execute the verification and analysis of the next i-th NrLtePair until i > n ends, and output the ping-pong reselection problem set ReselPingPongSet; where NrFreqHighPriReselThld is the high-priority reselection threshold configured on the 4G side. For example, when moving from 4G to 5G, when the UE stays on the current serving cell for more than 1 second, and during TReselectionNR, the measured level value of the high-priority target cell is higher than this threshold, it will reselect to the target cell;

[0162] Step P: Verify the problem of too late reselection start measurement: Verify Snonintrasearchp and Threshservinglowp in the 5G LCCUP table. If LCCUP.Snonintrasearchp - LCCUP.Threshservinglowp <= 0 exists, output the problem set of too late reselection start measurement for 5G, 5G_ReselMeasSet;

[0163] Step Q: Priority configuration problem on the 4G side: The 5G reselection priority should be higher than that of 4G. Verify the 4G side parameters. If CELLRESEL.CellReselPriority > NRNFREQ.NrFreqReselPriority + NRNFREQ.NrFreqReselSubPriority exists, output the problem set of inter-system reselection priority for the 4G side, 4G_ReselPriSet;

[0164] Step R: Priority configuration problem on the 5G side: Verify the 5G side parameters. If LCCUP.Cellreselectionpriority < eutrafreq_cellreselectionpriority + eutrafreq_cellreselectionsubpriority exists, output the problem set of inter-system reselection priority for the 5G side, 5G_ReselPriSet;

[0165] Seventh step: Problem of contradiction between connected state and idle state: If the N2L reselection threshold executed by 5G < the N2L handover threshold, it is easy to have the phenomenon that immediately switches to 4G as soon as entering the 5G connected state, causing unnecessary TAU and increasing the service interruption delay. Verify the 5G_QCI_PARAM table, associate Qrxlevmin of CDUP and Threshservinglowp of LCCUP according to gNodeBId and 5G_Cell_Id. If 2 * (5G side CDUP.Qrxlevmin + LCCUP.Threshservinglowp) < min(5G side LCCUP.B2_interrat_coverage_threshold1 - B2_interrat_coverage_hysteresis - 156, 5G side LCCUP.A2_interrat_coverage_threshold - A2_interrat_coverage_hysteresis - 156) exists, output the problem set of contradiction between connected state and idle state at the QCI level for 5G, 5G_RSHOSet.

[0166] Finally, combining the above seven steps, nine issue sets are output: PingPongSet, 5G_A1A2Set, 5G_A2B2Set, 4G_A2B2Set, ReselPingPongSet, 5G_ReselMeasSet, 4G_ReselPriSet, 5G_ReselPriSet, and 5G_RSHOSet. Among them, PingPongSet, 5G_A1A2Set, 5G_A2B2Set, and 4G_A2B2Set are QCI level, so each issue data is in list form, containing one or more QCI issue sets. PingPongSet is further divided into two sets: ServBasedPingPongSet and CovBasedPingPongSet. These can be merged into three issue lists based on the 4G eNodeBId and 4G_Local_Cell_Id, the 5G gNodeBId and 5G_Cell_Id, and the four IDs of 4G and 5G related to NrLtePair issues.

[0169] Reference Figure 8 The diagram illustrates a structural block diagram of a 4 / 5G interoperability problem processing device provided in an embodiment of the present invention, which may specifically include the following modules:

[0170] The communication data acquisition module 801 is used to acquire communication data corresponding to each communication cell in the target area. The communication cells include 4G cells and 5G cells. The communication data includes at least the LTE neighbor cell relationship of the 5G cell, the NR neighbor cell relationship of the 4G cell, the attribute information of the 4G cell, the attribute information of the 5G cell corresponding to the 5G cell, the access network interoperability parameters of the 5G cell, and the new air interface interoperability parameters of the 4G cell.

[0171] The neighbor cell pair generation module 802 is used to associate the LTE neighbor cell relationship with the 4G cell attribute information to generate a first 4 / 5G neighbor cell pair, associate the NR neighbor cell relationship with the 5G cell attribute information to generate a second 4 / 5G neighbor cell pair, and take the union between the first 4 / 5G neighbor cell pair and the second 4 / 5G neighbor cell pair to obtain a target 4 / 5G neighbor cell pair.

[0174] The first 5G base station identifier, the first 5G cell identifier, the first 4G base station identifier, and the first 4G local base station identifier are associated with the LTE neighbor cell relationship and deduplicated to generate the first 4 / 5G neighbor cell pair table.

[0175] The second 5G base station identifier, the second 5G cell identifier, the second 4G base station identifier, and the second 4G local base station identifier are associated with the LTE neighbor cell relationship and deduplicated to generate a second 4 / 5G neighbor cell pair table.

[0176] Take the union of the first 4 / 5G neighbor cell pair and the second 4 / 5G neighbor cell pair to obtain the target 4 / 5G neighbor cell pair table.

[0177] In one alternative embodiment, it further includes:

[0178] The data acquisition module is used to extract the handover threshold parameter table and the inter-system handover common parameter table corresponding to the 4G cell from the new air interface interoperation parameters. The handover threshold parameter table includes at least the first local cell identifier, QCI parameters, NRHOParamGroupId, and InterRatHoCommGroupId. The inter-system handover common parameter table includes at least the inter-system handover A1 RSRP threshold, inter-system handover A2 RSRP threshold, inter-system handover A1A2 RSRP threshold, coverage-based E-UTRAN handover to NR B1 event RSRP trigger threshold CovBasedNrB1RsrpThld, service-based E-UTRAN handover to NR B1 event RSRP trigger threshold ServBasedNrB1RsrpThld, and inter-system handover to new air interface parameter NrB1B2Hysteresis.

[0179] The first form generation module is used to associate the first 4G base station identifier corresponding to the 4G cell with the first local cell identifier, QCI parameters, NRHOParamGroupId and InterRatHoCommGroupId to obtain the first target form;

[0180] The second form generation module is used to generate a second target form by associating the inter-system handover A1 RSRP threshold, the inter-system handover A2 RSRP threshold, and the inter-system handover A1A2 RSRP threshold with the first local cell identifier and the InterRatHoCommGroupId as primary keys.

[0181] The 4G bearer table generation module is used to generate a 4G bearer table by using the first local cell identifier and the NRHOParamGroupId as the primary key, and associating CovBasedNrB1RsrpThld, ServBasedNrB1RsrpThld and NrB1B2Hysteresis.

[0182] In one alternative embodiment, the problem set output module 803 is specifically used for:

[0183] Traverse the target 4 / 5G neighbor cell pair table. For the i-th 4 / 5G neighbor cell pair in the target 4 / 5G neighbor cell pair table, obtain the target 5G base station identifier, target 5G cell identifier, target 4G base station identifier, and target 4G cell identifier of the i-th 4 / 5G neighbor cell pair.

[0184] Obtain from the preset 5G spectrum table the B2 event associated QCI, B2 event trigger threshold 1, B2 event trigger hysteresis value, A2 event associated QCI, A2 event trigger threshold, and A2 event trigger hysteresis value that are the same as the target 5G base station identifier and the target 5G cell identifier;

[0185] From the 4G bearer table, obtain QCI, CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld, which are identical to the target 4G base station identifier and the target 4G cell identifier.

[0186] For the B2 event associated QCI, the B2 event trigger threshold 1, the B2 event trigger hysteresis value, the A1 event associated QCI, the A1 event trigger threshold, and the A1 event trigger hysteresis value, the B2 event associated QCI and the A2 event associated QCI are externally joined. For QCI, CovBasedNrB1RsrpThld, NrB1B2Hysteresis, and ServBasedNrB1RsrpThld, the QCI is internally joined to generate several target QCI data that exist in both the access network interoperability parameters and the new air interface interoperability parameters.

[0187] Based on the aforementioned target QCI data, the target 4 / 5G neighbor cell pair table is checked for ping-pong handover issues, and a set of 4 / 5G interoperability issues corresponding to the target region is output.

[0188] In one alternative embodiment, the problem set output module 803 is specifically used for:

[0189] Iterate through the target QCI data. For each target QCI data, compare the records with the same QCI. If there exists (ServBasedNrB1RsrpThld+0.5*NrB1B2Hysteresis)-min(B2 event trigger threshold 1-B2 event trigger hysteresis value-156, A2 interface average threshold-A2 interface average hysteresis value-156)<first preset threshold, then output the business-based ping-pong problem set ServBasedPingPongSet_i.

[0190] Traverse the several target QCI data. For each target QCI data, compare the records with the same QCI. If (CovBasedNrB1RsrpThld + 0.5 * NrB1B2Hysteresis) - min(B2 event trigger threshold 1 - B2 event trigger hysteresis value - 156, A2 event trigger threshold - A2 event trigger hysteresis value - 156) < the second preset threshold, then output the coverage-based ping-pong problem set CovBasedPingPongSet_i;

[0191] Take the union between the ServBasedPingPongSet_i and CovBasedPingPongSet_i to obtain the connected-state ping-pong problem set PingPongSet_i.

[0192] In an optional embodiment, the problem set output module 803 is further specifically configured to:

[0193] Taking the 5G base station identifier, 5G cell identifier, A1 event associated QCI, A2 event associated QCI, and B2 event associated QCI in the access network interoperability data as the primary key, associate the same QCI to generate a 5G bearer table, and the 5G bearer table includes several 5G QCI data;

[0194] Traverse the 5G bearer table. For each 5G QCI data, compare the records with the same 5G base station identifier, 5G cell identifier, and QCI. If (A1 event trigger threshold + A1 event trigger hysteresis value s) - (A2 event trigger threshold - A2 event trigger hysteresis value) < the third preset threshold, then output the measurement interval too small problem set 5G_A1A2Set;

[0195] If A2 event trigger threshold - A2 event trigger hysteresis value < B2 event trigger threshold 1 - B2 event trigger hysteresis value, then output the start measurement too late problem set 5G_A2B2Set.

[0196] In an optional embodiment, the 4G bearer table includes several 4G QCI data, and the problem set output module 803 is further specifically configured to:

[0197] Traverse the 4G bearer table. For each 4G QCI data, compare the records with the same QCI. If InterRatHoNrA1ThldRsrp - InterRatHoNrA2ThldRsrp < the fourth preset threshold, then output the start measurement too late problem set 4G_A1A2Set on the 4G side.

[0198] In an optional embodiment, the problem set output module 803 is further specifically configured to:

[0199] Obtain from the 5G spectrum table the lowest received level and low priority serving cell RSRP decision threshold that are the same as the target 5G base station identifier and the target 5G cell identifier, as well as the minimum received level and NR frequency high priority reselection threshold that are the same as the target 4G base station identifier and the target 4G cell identifier;

[0200] If (the minimum received level + the NR frequency high priority reselection threshold) - (the lowest received level of the cell + the low priority serving cell RSRP decision threshold) < the fifth preset threshold, then output the ping-pong reselection problem ReselPingPongSet_i, end the verification and analysis process of the i-th 4 / 5G neighbor cell pair, and continue to repeat this step to perform the verification and analysis of the next i-th 4 / 5G neighbor cell pair until all 4 / 5G neighbor cell pairs have been verified and the ping-pong reselection problem set ReselPingPongSet is output.

[0201] In an optional embodiment, the problem set output module 803 is further configured to:

[0202] Obtain the inter-frequency neighbor cell measurement threshold and the low-priority serving cell RSRP decision threshold from the 5G spectrum table. If the inter-frequency neighbor cell measurement threshold - the low-priority serving cell RSRP decision threshold ≤ 0, then output the problem set 5G_ReselMeasSet for late reselection testing.

[0203] In one optional embodiment, the new air interface interoperability parameters include the cell reselection frequency point priority within the LTE system, and the access network interoperability parameters include the cell reselection frequency point priority within the NR system and the cell reselection frequency point sub-priority within the NR system. The problem set output module 803 is further configured to:

[0204] If there exists a cell reselection frequency point priority in the LTE system that is greater than the sum of the cell reselection frequency point priority and the sub-priority of the cell reselection frequency point in the NR system, then output the 4G-side inter-system reselection priority problem set 4G_ReselPriSet.

[0205] In an optional embodiment, the access network interoperability parameters include cell reselection priority, priority during reselection determination, and sub-priority during reselection determination. The problem set output module 803 is further configured to:

[0206] If there exists a cell reselection priority that is lower than the priority at the time of reselection and the sub-priority at the time of reselection, then output the 5G side inter-system reselection priority problem set 5G_ReselPriSet.

[0207] In one optional embodiment, the 5G cell includes a CU cell and a DU cell, and the problem set output module 803 is further configured to:

[0208] Extract the cell DU parameters corresponding to the DU cell and the logical cell CU parameters corresponding to the CU cell from the 5G bearer table. The cell DU parameters include the minimum access level. The logical cell CU parameters include the low priority serving cell RSRP decision threshold.

[0209] If the minimum access level of the DU cell + the low priority serving cell RSRP decision threshold of the CU cell < min(B2 event trigger threshold 1 - B2 event trigger hysteresis value - 156 of the CU cell, A2 event trigger threshold - A2 event trigger hysteresis value - 156 of the CU cell), then the QCI-level connected state and idle state contradiction problem set 5G_RSHOSet is output.

[0210] As the device embodiment is basically similar to the method embodiment, the description is relatively simple, and relevant parts can be found in the description of the method embodiment.

[0213] Figure 9 A schematic diagram of the hardware structure of an electronic device for implementing various embodiments of the present invention.

[0214] The electronic device 900 includes, but is not limited to, components such as: a radio frequency unit 901, a network module 902, an audio output unit 903, an input unit 904, a sensor 905, a display unit 906, a user input unit 907, an interface unit 908, a memory 909, a processor 910, and a power supply 911. Those skilled in the art will understand that the electronic device structure involved in the embodiments of the present invention does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements. In the embodiments of the present invention, the electronic device includes, but is not limited to, mobile phones, tablet computers, laptop computers, PDAs, in-vehicle terminals, wearable devices, and pedometers.

[0215] It should be understood that, in this embodiment of the invention, the radio frequency unit 901 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink data from the base station and processes it with the processor 910; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 901 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. Furthermore, the radio frequency unit 901 can also communicate with networks and other devices through a wireless communication system.

[0216] Electronic devices provide users with wireless broadband internet access through network module 902, such as helping users send and receive emails, browse web pages, and access streaming media.

[0217] The audio output unit 903 can convert audio data received by the radio frequency unit 901 or the network module 902 or stored in the memory 909 into audio signals and output them as sound. Furthermore, the audio output unit 903 can also provide audio output related to specific functions performed by the electronic device 900 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 903 includes a speaker, a buzzer, and a receiver, etc.

[0218] Input unit 904 is used to receive audio or video signals. Input unit 904 may include a graphics processing unit (GPU) 9041 and a microphone 9042. The GPU 9041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on display unit 906. The image frames processed by GPU 9041 can be stored in memory 909 (or other storage medium) or transmitted via radio frequency unit 901 or network module 902. Microphone 9042 can receive sound and process such sound into audio data. The processed audio data can be converted into a format that can be transmitted to a mobile communication base station via radio frequency unit 901 in telephone call mode.

[0219] The electronic device 900 also includes at least one sensor 905, such as a light sensor, a motion sensor, and other sensors.

As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used to identify the posture of the electronic device (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. The sensor 905 may also include a fingerprint sensor, pressure sensor, iris sensor, molecular sensor, gyroscope, barometer, hygrometer, thermometer, infrared sensor, etc., which will not be described in detail here.

Touch panel 9071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 9071). Touch panel 9071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to processor 910, which receives and executes commands from processor 910. In addition, touch panel 9071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave.

Subsequently, the processor 910 provides corresponding visual output on the display panel 9061 based on the type of touch event. It is understood that in one embodiment, the touch panel 9071 and the display panel 9061 are implemented as two independent components to realize the input and output functions of the electronic device.
