A serving Cell (Cell) at a network device is an area of signal coverage for the network device.
Optionally, the target user may include one or more of the following:
All users initially accessing the service cell;
All users establishing reconnection with the serving cell;
All users that successfully initiate a radio resource control (Radio Resource Control, RRC) recovery procedure in the serving cell;
All users handed over from other cells to the cell;

a user which establishes reconnection with a serving cell within a cross-region coverage detection duration;
A user which successfully initiates an RRC recovery process in a serving cell within a coverage detection duration;
And switching from other service cells to the user of the service cell in the coverage detection duration.
Step 102, determining whether the serving cell is a coverage cell based on the target user's time advance (TIMING ADVANCE, TA) measurement.
In some embodiments, the serving cell is determined to be a coverage cell in the event that the number of target users for which the TA measurement is greater than the TA decision threshold is greater than a preset number.
In the method for detecting the coverage area provided in the embodiment of fig. 1, the target user in the service cell of the network device is determined, and whether the service cell is the coverage area is determined based on the time advance TA measured value of the target user, so that the outfield tester can be prevented from moving in the service cell while carrying the test device on a transportation means or walking, and the accuracy of detecting whether the service cell is the coverage area is improved.
In addition, in the related art, the outfield tester carries the test equipment to move in the service cell by taking a vehicle or walking, that is, the vehicle and the related technician are required to collect test data, so that the difficulty of finding the coverage area of the cell is found, and the network optimization cost of the operator is high. In the application, whether the service cell is a cross-region coverage cell is determined based on the TA measured value of the time advance of the target user, so that the need of collecting test data by vehicles and related technicians can be avoided, the difficulty of finding the coverage cell of the region is reduced, and the network optimization and operation and maintenance costs are saved.
Further, the network device discovers the coverage cell based on the coverage detection method provided by the application, and can be rapidly deployed in a large area without adding detection components. And the method for detecting the cross-region coverage discovers the cross-region coverage cell, so that the network equipment is more intelligent, and the product competitiveness of the network equipment is improved.
In some embodiments, step 102 may include:
determining a handoff user among the target users based on the TA measurement values of the target users;
Based on the number of target users and the number of overlay users, it is determined whether the serving cell is an overlay cell.
Specifically, based on the number of target users and the number of coverage users, it is determined whether the serving cell is a coverage cell, and further, the accuracy of detecting whether the serving cell is a coverage cell can be improved.
In some embodiments, a user of the target user whose TA measurement is greater than or equal to the TA decision threshold is determined to be a handoff user.
The TA decision threshold may be pre-stored in the network device.
In some embodiments, a ratio between the number of overlay users and the number of target users is determined; and determining the serving cell as the coverage cell in the case that the ratio is greater than the coverage user decision threshold.
The handoff user decision threshold may be a handoff user decision threshold pre-stored in the network device.
In some embodiments, step 101 may comprise:
Acquiring a cross-region coverage detection time length;
and determining the target user in the service cell of the network equipment in the coverage detection duration.
Unlike the prior art, in the prior art, the outfield tester takes a long time to move in the serving cell with the test device in a vehicle or walking, so that the test device records enough test data, and therefore, the time for detecting whether the serving cell is a coverage cell is long, and the detection efficiency is low. In the application, the target user in the service cell of the network equipment is determined in the time of the coverage detection duration, and then whether the service cell is the coverage cell is determined based on the time advance TA measured value of the target user, so that the detection duration is limited in the time of the coverage detection duration, and whether the service cell is the coverage cell is detected in a shorter time, and further the detection efficiency is improved.
In some embodiments, determining a target user in a serving cell of a network device for a handoff detection duration comprises:
Acquiring CRC state information of the user to be selected within the coverage detection duration;
Determining the user with correct CRC state information in the users to be selected as a target user in a service cell of the network equipment;
the candidate users include one or more of the following:
A user initially accessing a service cell;
a user establishing a reconnection with a serving cell;
a user that successfully initiates a radio resource control, RRC, recovery procedure in a serving cell;
a user handed over from other serving cells to the serving cell.
In the application, the user with correct CRC state information in the user to be selected is determined as the target user in the service cell of the network equipment, thereby improving the accuracy of determining the target user and further improving the accuracy of detecting whether the service cell is covered by the cell or not.
In some embodiments, acquiring Cyclic Redundancy Check (CRC) status information for a candidate user during a handoff detection duration includes:
acquiring the utilization rate of a physical resource module PRB of a serving cell;
and under the condition that the PRB utilization rate is determined to start the cross-region coverage detection task, acquiring Cyclic Redundancy Check (CRC) state information of the candidate user within the cross-region coverage detection duration.
In some embodiments, obtaining physical resource module, PRB, utilization of a serving cell includes:
acquiring the uplink PRB utilization rate and the downlink PRB utilization rate of a serving cell;
And determining the PRB utilization rate of the serving cell based on the uplink PRB utilization rate and the downlink PRB utilization rate.
Alternatively, the PRB utilization of the serving cell may be determined based on two ways.
Mode 11 determines an average value of the uplink PRB utilization and the downlink PRB utilization as the PRB utilization of the serving cell.
Mode 12, determining a first product of an uplink PRB utilization rate and a preset uplink weight;
determining a second product of the utilization rate of the downlink PRB and a preset downlink weight;
and determining the sum of the first product and the second product as the PRB utilization rate of the serving cell.
Alternatively, the initiation of the coverage detection task based on PRB utilization determination may be accomplished in two ways.
In the mode 21, when the PRB utilization of the serving cell is smaller than the PRB utilization decision threshold, it is determined to start the handover coverage detection task.
In the mode 22, when the preset handover coverage detection switch is in an on state and the PRB utilization of the serving cell is smaller than the PRB utilization decision threshold, it is determined to start a handover coverage detection task.
Alternatively, the PRB utilization decision threshold may be a PRB utilization decision threshold pre-stored in the network device.
In the application, the cross-region coverage detection occupies the system resources of the network equipment, so that under the condition that the PRB utilization rate of the serving cell is smaller than the PRB utilization rate judgment threshold, the start of the cross-region coverage detection task is determined, and the network equipment can be ensured to have enough system resources to execute the cross-region coverage detection task, thereby avoiding the detection failure of the cross-region coverage detection task caused by insufficient system resources and improving the detection success rate.
In some embodiments, the handoff detection task is stopped with a preset handoff detection switch in an off state.
In some embodiments, the handoff detection task is stopped if the pre-set handoff detection switch is in an on state and the PRB utilization of the serving cell is greater than or equal to a PRB utilization decision threshold.
In some embodiments, the duration of the coverage detection may be obtained in two ways.
And 31, receiving parameter configuration information sent by the management function, and acquiring the cross-region coverage detection duration from the parameter configuration information, wherein the parameter configuration information comprises the cross-region coverage detection duration.
Optionally, the parameter configuration information may further include a handover coverage user decision threshold, a TA decision threshold, and a PRB utilization decision threshold. The management function is, for example, an Operation maintenance center (Operation AND MAINTENANCE CENTER, OMC).
Mode 32, acquiring a handoff detection configuration instruction, and acquiring a handoff detection duration from the handoff detection configuration instruction, wherein the handoff detection instruction comprises the handoff detection duration.
The handoff detection configuration instruction is a configuration instruction directed to the network device.
Optionally, the handover detection configuration instruction may further include a handover user number decision threshold, a TA decision threshold, and a PRB utilization decision threshold.
Optionally, the management function and the network device may add the following cell-level parameters (as shown in table 1) to flexibly configure the coverage detection duration, the coverage user decision threshold, the TA decision threshold, and the PRB utilization decision threshold.
TABLE 1
Note that, for the coverage detection period, the six parameter configurations of NRTASTARTDATE, NRTASTARTTIMEHOUR, NRTASTARTTIMEMINUTE, NRTAENDDATE, NRTAENDTIMEHOUR, NRTAENDTIMEMINUTE in table 1 are adopted.
Duration of the coverage detection: and setting a cross-region coverage detection time length through a detection timer, and judging whether the serving cell is in the cross-region coverage after the time of the timer (the timing time length of the detection timer is equal to the cross-region coverage detection time length). In order to shorten the time period of the coverage detection, a default value of 15 minutes is set. The larger the time length of the coverage detection, the more accurate the detected data, but the detection efficiency becomes low.
TA decision threshold: when the frequency band of the signal of the network device is 700 mega (M) (5G network), the farthest coverage distance of the network device is slightly lower than the range of about 5 kilometers (km), and the effective coverage distance is about 2.2 km. At a subcarrier spacing equal to 15 kilohertz (Khz), the coverage distance is approximately 78.125M in the case of a signal experiencing 1TA, so that the effective coverage of the serving cell corresponds to a TA of approximately 28.16 (2.2x1000/78.125=28.16) in the case of a frequency band of 700M. Thus, the default value of the TA decision threshold may be set to 28. Optionally, the TA decision threshold may be adjusted according to the deployment of the spacing between the base stations.
And (3) a cross-region coverage user number judgment threshold: the initial value may be set to 5%, i.e. it is considered that in the serving cell, when 5% of the user TAs are abnormally large, the serving cell is confirmed as a coverage cell. In the practical application process, the judgment threshold of the number of the coverage users can be dynamically adjusted.
PRB utilization decision threshold: the system resource of the base station is occupied by the coverage detection, the variable is added to judge the busy degree of the service cell, and the coverage detection task is dynamically configured. The PRB utilization decision threshold default may be configured to be 50%, and if the PRB utilization of the serving cell is lower than 50%, it indicates that the serving cell is not busy, and a coverage detection task is configured for the serving cell.
Optionally, the network device includes a base station Operation maintenance (Operation AND MAINTENANCE), a high Layer (HIGH LEVEL, HL) and a Layer 2 (Layer 2, L2), and the Operation maintenance function, the high Layer and the Layer 2 can implement the handoff coverage detection method provided by the present application through the following information interaction process shown in fig. 2.

Optionally, in the case that the CRC status information of the candidate user is incorrect, the determination is repeated as to whether the CRC status information of the candidate user is correct. In the application, whether CRC state information of the user to be selected is correct or not is repeatedly judged, and misjudgment of flow caused by Msg1 false detection can be avoided, thereby improving accuracy of determining the target user.
Step 207, L2 sends the TA measurement of the target user to HL.
Specifically, the method for obtaining the TA measurement value of the target user by using the L2 may refer to the prior art, and will not be described herein.

For each target user, N is increased by 1 before the end of the coverage detection period if its TA measurement is greater than or equal to the TA decision threshold. At the end time of the coverage detection period, N at this time is determined as the number of coverage users.
Alternatively, the number of target users may be L2 sent to HL.
