Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
First, the terms involved in the embodiments of the present application will be briefly described:
5G is a new generation broadband mobile communication technology with high speed, low time delay and large connection characteristics, and is a network infrastructure for realizing man-machine object interconnection. 5G is as a novel mobile communication network, not only is the problem of person-to-person communication solved, but also the problem of person-to-object communication is solved, and the application requirements of the Internet of things such as mobile medical treatment, internet of vehicles, intelligent home, industrial control, environmental monitoring and the like are met, wherein the user is provided with augmented reality, virtual reality, ultra-high definition (3D) video and the like to be more immersive and extreme business experience. Finally, 5G is permeated into various fields of various industries of economy and society, and becomes a key novel infrastructure for supporting digitization, networking and intelligent transformation of economy and society. The 5G international technical standard is focused on meeting the requirements of flexible and various Internet of things. On the basis of orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA) and multiple-in multiple-out (MIMO) base technologies, 5G is a flexible brand new system design for supporting three application scenarios. In terms of frequency bands, unlike 4G supporting medium and low frequency, 5G simultaneously supports medium and low frequency and high frequency bands in consideration of limited medium and low frequency resources, wherein the medium and low frequency meets the requirements of coverage and capacity, the high frequency meets the requirement of capacity improvement in a hot spot area, and 5G designs a unified technical scheme aiming at the medium and low frequency and the high frequency and supports hundred MHz basic bandwidth. In order to support high-rate transmission and better coverage, 5G adopts LDPC, polar novel channel coding schemes, larger-scale antenna techniques with stronger performance, and the like. In order to support low latency and high reliability, 5G adopts short frame, fast feedback, multi-layer/multi-station data retransmission, etc.
A user terminal, which is a concept in mobile communication, is used to instruct a mobile device that is accessed into a 5G network and is used by a user. In the present application, the user terminal is implemented as a mobile terminal connected to a 5G network, such as a mobile phone.
The access network device, i.e. the interface device implemented as a public mobile communication base station, is an interface device for accessing a user terminal to the internet, and refers to a radio transceiver station for transmitting information with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. In the application, a communication connection is established between the access network device and the user terminal, and the user terminal can be connected to the Internet through the access network device. In this case, the access network device corresponds to a serving cell, that is, indicates that the serving cell corresponding to the access network device is a primary serving cell of the user terminal.
In the process of establishing communication connection between the user terminal and the access network device, if the number of overlapping cells corresponding to the user terminal is too large, the use of the user terminal is unstable, so that the characteristics of the 5G network are required to be combined to evaluate the overlapping coverage state of the network.
Fig. 1 is a flow chart of a method for evaluating coverage status of a beam-based network according to an exemplary embodiment of the present application, where the method is applied to an access network device for illustration, and the method includes:
and step 101, receiving a measurement report sent by the user terminals in the user terminal set in a target period.
In the embodiment of the application, a network connection relationship is established between the access network equipment and the user terminal, and the user terminal is connected to the network through the access network equipment. Thus, as a primary serving cell for the user terminal, the user terminal may periodically receive measurement reports transmitted by the user terminal.
In the embodiment of the application, the user terminal can periodically perform self-checking, generate a measurement report and then automatically upload the measurement report, or the user terminal receives a measurement report sending instruction sent by the access network device, performs self-checking based on the measurement report sending instruction and feeds back to the access network device.
In the embodiment of the application, the user terminal belongs to a user terminal set, and the user terminal set is a set of user terminals taking the access network and the device as a main service cell.
In the embodiment of the present application, the measurement report includes a standard synchronization reference signal level and at least two neighbor synchronization reference signal levels. The standard synchronization reference signal level indicates the level value of the reference beam corresponding to the main service cell and the user terminal, and the neighbor synchronization reference signal level indicates the level value of at least two beams transmitted by at least one candidate service cell received by the user terminal.
In the embodiment of the present application, by combining the characteristics of the 5G network, the signal is collected for the beam intensity that can be received by the user terminal. On the basis, the access network equipment aims at the received level value of the reference beam directly related to the user terminal in the main service cell which is used for providing service for the user terminal and the candidate service cell which is not used for providing service for the user terminal. Alternatively, the at least two beams may be from one same candidate serving cell, or may be from at least two candidate serving cells, and the cell from which the at least two beams are derived is not limited in this application.
Step 102, determining a sub-sample overlapping coverage state corresponding to the user terminal in the target period based on the standard synchronization reference signal level and at least two neighbor synchronization reference signal levels.
In the embodiment of the present application, after determining the standard synchronization reference signal level and at least two neighbor synchronization reference signal levels, it is determined whether the ue is in the overlapping coverage state in the target period according to the corresponding strength values. I.e. one sub-sample overlap coverage status, indicating the overlap coverage status of one user terminal within one target period.
And step 103, evaluating the network overlapping coverage state corresponding to the main service cell by combining at least two sub-sample overlapping coverage states in the target time period.
In the embodiment of the present application, the target period includes at least two target periods, and the user terminal set includes at least two user terminals, so the number of the sub-sample overlapping coverage states is at least two. In this case, the network overlapping coverage status of the primary serving cell is evaluated based on the at least two sub-sample overlapping coverage status. In one example, determining a network overlapping coverage status rate of the primary serving cell by indicating a proportion of the user terminals in overlapping coverage status in the sub-sample overlapping coverage status; in another example, image drawing is performed based on the sub-sample overlapping coverage state and the measurement time and place of the sub-sample overlapping coverage state, and a network overlapping coverage hot area diagram of the main serving cell is obtained, so as to evaluate the network overlapping coverage state corresponding to the main serving cell.
In the embodiment of the application, the overlapping coverage state of the network corresponding to the main serving cell is directly evaluated through the overlapping coverage state of the wave beams.
In summary, in the method provided in the embodiment of the present application, in an application scenario of a 5G network, a sub-overlapping coverage state of a target period is determined by periodically receiving a beam used for providing services to a user terminal by a main serving cell to be tested, where the beam has a standard synchronization reference signal level and a neighbor synchronization reference signal level, and the sub-overlapping coverage states are combined with each other, and finally, the network overlapping coverage state is evaluated. In the process of evaluating the overlapping coverage of the network, the unit level of evaluation is improved to the level of a narrow beam level, so that the accuracy of network structure evaluation is improved, and under the condition of providing a reference for signal optimization of the beam level, the evaluation efficiency of the overlapping coverage state of the network is improved by adapting to the condition of a 5G network.
Fig. 2 is a flowchart of another method for evaluating coverage status of beam-based network according to an exemplary embodiment of the present application, please refer to fig. 2, wherein the method includes:
step 201, receiving measurement reports sent by user terminals in a user terminal set in a target period.
This step is similar to step 101 and will not be described in detail here.
In the embodiment of the present application, the level value in the measurement report fed back by the ue is a level value corresponding to a beam in another neighboring cell in the same frequency region as the primary serving cell, where the level value is received by the ue.
Optionally, the content of at least two neighbor synchronization reference signal levels that should be included in the measurement signal is as follows
Table 1 shows:
the adjacent cell sector number is the cell identifier of other cells different from the main service cell, the adjacent cell beam number is the beam identifier corresponding to the beam in the adjacent cell, the unit of the synchronous reference signal level is dB, and the level value when the user terminal receives the beam is indicated.
In addition, the measurement signal may include a standard synchronization reference signal level.
In one example, the content details in the measurement information are shown in table 1 below:
table 1: measurement signal content details:
| neighbor sector number | Neighbor beam numbering | Synchronizing reference signal level | |
| 1 | C2 | Beam_1 | -60dBm |
| 2 | C2 | Beam_2 | -62dBm |
| 3 | C3 | Beam_7 | -63dBm |
| 4 | C3 | Beam_8 | -68dBm |
| 5 | C3 | Beam_1 | -75dBm |
| 6 | C2 | Beam_3 | -77dBm |
| 7 | C2 | Beam_8 | -90dBm |
| 8 | C3 | Beam_6 | -95dBm |
In this example, the standard synchronization reference signal level is-58 dBm.
Step 202, determining a deviation threshold corresponding to a standard synchronization reference signal level.
In the embodiment of the application, the measurement report includes a standard synchronization reference signal level and at least two neighbor synchronization reference signal levels, and for the difference value of the two, the access network device pre-stores a standard corresponding to the difference value of the two. Alternatively, in the example as described in step 201, the deviation threshold is set to 6dBm.
In step 203, overlapping coverage is determined based on the standard synchronization reference signal and a deviation threshold.
As described above, when the standard synchronization reference signal level is-58 dBm and the difference corresponding to the standard synchronization reference signal level is 6dBm, the overlapping coverage is-52 dBm to-64 dBm.
And 204, determining that the comparison result corresponding to the neighbor synchronization reference signal is an overlapping coverage result in response to the neighbor synchronization reference signal being in the overlapping coverage.
In step 205, in response to the neighbor synchronization reference signal not being in the overlapping coverage, it is determined that the comparison result corresponding to the neighbor synchronization reference signal is a non-overlapping coverage result.
Steps 204 to 205 are the judgment of the comparison result corresponding to each neighbor synchronization reference signal. And judging whether the neighbor synchronization reference signal is in the overlapped coverage range or not when the neighbor synchronization reference signal is in the specific value.
Optionally, in the example as described in step 201, the results indicated by the neighbor beams of Beam numbers beam_1, beam_2, and beam_7 are overlapping coverage results, and the other overlapping coverage results are non-overlapping coverage results.
In step 206, in response to the number of overlapping coverage results reaching the comparison result number threshold, determining that the subsampled overlapping coverage state is an overlapping coverage state.
In step 207, in response to the number of overlapping coverage results not reaching the comparison result number threshold, determining that the sub-sample overlapping coverage state is a non-overlapping coverage state.
Steps 206 through 207 are processes for determining the subsampled overlapping coverage status. The comparison result number threshold is a natural number, and the comparison result number threshold is smaller than the number of comparison results. In the example as described in step 201, the comparison result number threshold is set to 3. For the measurement data as described in step 201, the sub-sample overlap state may be determined.
Step 208, determining a first number of sub-sample overlapping coverage states in the overlapping coverage state and a second number of sub-sample overlapping coverage states within the target time period.
In the embodiment of the present application, the target period includes at least two periods, and each period corresponds to a sub-sample overlapping coverage state.
In this case, counting of the first number and the second number is performed based on the subsampled overlapping coverage state.
In step 209, the ratio of the first number to the second number is determined to be the beam overlap coverage ratio.
In the example shown in step 201, the ratio of the first number to the second number is the beam overlap coverage ratio corresponding to the target time period. Alternatively, assuming that the second number is total_m and the first number is ol_m, the Beam overlap coverage ratio may be determined to be beam_ol=ol_m/total_m.
And step 210, evaluating the network overlapping coverage state corresponding to the main service cell based on the beam overlapping coverage ratio.
In the embodiment of the application, the network overlapping coverage corresponding to the main service cell can be evaluated by performing the form of beam overlapping coverage ratio determination. That is, during this evaluation, the network coverage index is sunk to the beam level, and the network coverage ratio shown in the embodiments of the present application essentially indicates the coverage ratio of the beam. On this basis, after determining the network overlapping coverage status of the primary serving cell, the beam may be directly adjusted. In one example, after the evaluation of the network overlapping coverage status corresponding to the primary serving cell is performed, the evaluation result indicates that the overlapping coverage is greater than the overlapping coverage threshold, and then the adjustment of the beam azimuth or the adjustment of the beam power is performed for the target beam in the primary serving cell.
In summary, in the method provided in the embodiment of the present application, in an application scenario of a 5G network, a sub-overlapping coverage state of a target period is determined by periodically receiving a signal level having a standard synchronization reference signal and a neighbor synchronization reference signal level for a main serving cell to be tested, and a plurality of sub-overlapping coverage states are combined, and finally, the network overlapping coverage state is evaluated. In the process of evaluating the overlapping coverage of the network, the unit level of evaluation is improved to the level of a narrow beam level, so that the accuracy of network structure evaluation is improved, and under the condition of providing a reference for signal optimization of the beam level, the evaluation efficiency of the overlapping coverage state of the network is improved by adapting to the condition of a 5G network.
