[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of the embodiments of the present invention through specific implementation methods combined with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Embodiment 1:

[0033] In view of the problem that the base station in the related technology only pays attention to the information related to the downlink channel quality of the cell when performing cell quality statistics, resulting in the problem that only the downlink channel quality of the cell can be used as the basis in the process of switching or redirection. In the process of performing cell quality statistics, the cell channel quality acquisition method provided in this embodiment can set a cell channel quality statistics table for the cell that needs to be counted, wherein the cell channel quality statistics table includes the cell quality parameters that need to be counted and the unique identification information of the cell, so that one cell can only correspond to one cell channel quality statistics table; and in the set cell channel quality statistics table, the cell quality parameters include the uplink channel quality parameters of the cell, and when performing cell quality parameter statistics, the cell quality parameter value of the cell can be obtained based on the interactive information obtained by interaction with the terminal, and the corresponding cell quality parameters in the cell channel quality statistics table of the cell are updated and stored in the cell quality summary database for call, so that when the cell channel quality is needed as the basis for cell switching or redirection, the cell uplink channel quality can be selectively used as the basis according to the needs, so that the basis selection of operations such as cell switching or redirection is larger and more flexible, and the operation results are more accurate, thereby further improving the user experience satisfaction.

[0034] It should be understood that in this embodiment, it is not limited that the cell channel quality statistics table set for all cells that need to count the cell quality must include the uplink channel quality parameter; in some application scenarios, it can be set to need to count the uplink channel quality of some or a certain type of cells when performing quality statistics, while it is optional not to count the uplink channel quality of other cells; in other application scenarios, uplink channel quality statistics can be selectively performed for all cells that need to perform quality statistics; the specific method can be flexibly selected according to needs. And it should be understood that in some application scenarios, for all cells to be subjected to quality statistics, the contents included in the generated cell channel quality statistics table can be the same or different; for example, the same cell quality parameters can be included, and when some cells do not need to perform uplink channel quality statistics, the uplink channel quality parameters in the cell quality parameters can be not updated accordingly. And in this embodiment, the statistical uplink channel quality parameters can include at least one of the quality parameters of the uplink control channel and the uplink service channel.

[0035] For ease of understanding, this embodiment is described below in conjunction with Figure 1 The cell channel quality acquisition method shown is described as an example, including:

[0036] S101: Acquire interaction information with a terminal in a cell.

[0037] In this step, the communication device obtains the interaction information between the terminal and the cell. The communication device may be, but is not limited to, a base station device on the network side, or may be other network side devices used for cell quality statistics. In addition, it should be understood that the name of the base station device may change in subsequent communication networks, as long as it is an equivalent device that implements the corresponding base station function.

[0038] It should be understood that the interactive information between the terminal and the present embodiment may be any message that carries information that can characterize the cell channel quality. The interactive information may directly carry relevant information of the cell quality parameter value, or may carry relevant information for determining the cell quality parameter value, or determine the cell quality parameter value according to the reception of the interactive information; for example, packet loss rate, reception accuracy (or error rate), etc.

[0039] It should be understood that, in this embodiment, when performing cell quality statistics, it is not limited to performing statistics based only on the interaction information with the terminal, but corresponding statistics can also be performed based on corresponding information that can characterize the cell channel quality obtained from other network devices as needed.

[0040] S102: Acquire a cell quality parameter value of the cell according to the interaction information.

[0041] In this embodiment, when the interactive information directly carries relevant information of the cell quality parameter value, the corresponding cell quality parameter value can be directly extracted from the interactive information. When the interactive information carries relevant information for determining the cell quality parameter value, the relevant information can be extracted to perform corresponding calculations to obtain the corresponding cell quality parameter value. When the cell quality parameter value is determined based on the reception of the interactive information, the reception of the interactive information can be correspondingly counted, and the corresponding cell quality parameter value can be calculated using a corresponding algorithm based on the statistical results.

[0042] S103: According to the obtained cell quality parameter value, the corresponding cell quality parameter in the cell channel quality statistics table of the cell is updated, the cell quality parameter includes the uplink channel quality parameter of the cell, and the cell channel quality statistics table includes unique identification information of the cell.

[0043] In this embodiment, updating the cell quality parameter includes: when the difference between the cell quality parameter value before the update and the cell quality parameter value obtained in S102 reaches the condition that requires updating, updating the value of the cell quality parameter to the cell quality parameter value obtained in step S102, or adding a value, and the added value is the cell quality parameter value obtained in S102; otherwise, the value of the cell quality parameter can be kept unchanged.

[0044] In addition, it should be understood that the uplink channel quality parameter in this embodiment may include at least one of various parameters that can characterize the uplink channel quality of the cell, and may be flexibly set according to the application scenario requirements. For example, in one example, the uplink channel quality parameter may include but is not limited to at least one of a single resource block signal-to-interference noise ratio (single RB SINR) and an uplink block error rate bler.

[0045] In this embodiment, the unique identification information of the cell can be any information that can uniquely represent the cell. For example, in one example, the unique identification information of the cell may include a combination of base station identification information and cell identification information. When the cell identification information of different base station cells is different, the unique identification information of the cell may also include only the cell identification information.

[0046] S104: Store the updated cell channel quality statistics table in the cell quality summary database for later use.

[0047] In this embodiment, the cell quality summary database can store the cell channel quality statistics table of each cell that needs to be counted for quality; it can also be used to store the cell channel quality statistics table of the specified part of the cells that need to be counted for quality. In this embodiment, the cell quality summary database can be set on the communication device, or on the background management device of the communication device. For example, when the communication device is a base station, it can be set on the background management device of the base station. In this way, when needed, the cell channel quality statistics table of the corresponding cell can be called out from the cell quality summary database according to the demand; and the called cell channel quality statistics table includes the uplink channel quality parameters used to characterize the uplink channel quality of the cell. Compared with the related art, the base station only pays attention to the downlink channel quality related information of the cell when performing cell quality statistics, resulting in the situation that only the downlink channel quality of the cell can be used as the basis in the process of switching or redirection, etc., the uplink channel quality of the cell can be selectively used as the basis according to the demand, so that the selection of the basis for operations such as cell switching or redirection is larger and more flexible, and the operation results are more accurate, which improves the success rate of wireless network switching and the ability to perceive wireless network services, and can also improve the utilization efficiency of the wireless network.

[0048] Optionally, in this embodiment, the cell quality parameters in the cell channel quality statistics table may be set to include only uplink channel quality parameters characterizing the cell uplink channel quality according to demand. In other examples of this embodiment, in order to further improve the requirements of cell switching or redirection, other corresponding quality parameters may be flexibly added to the cell quality parameters in the cell channel quality statistics table.

[0049] For example, in an application scenario of the present embodiment, the cell quality parameters also include reference signal ReferenceSignal reception parameters; when necessary, the cell channel quality statistics table of the corresponding cell can be directly called to extract the value of the reference signal reception parameters of the cell from the cell channel quality statistics table. In some examples, the cell quality parameters and uplink channel quality parameters of the cell can be independently counted separately and independently called in subsequent calls. In some examples of the present embodiment, in order to improve efficiency and accuracy, the reference signal reception parameters of the cell can also be associated with the uplink channel quality parameters for statistics. At this time, the cell channel quality statistics table of the cell includes uplink channel quality parameters corresponding to reference signal reception parameters with values ​​in different intervals. In the present embodiment, the interval values ​​of the reference signal reception parameters can be flexibly set according to needs, and the lengths of different intervals can be the same or different.

[0050] In this example, obtaining a cell quality parameter value of a cell according to the interaction information includes:

[0051] Acquire a reference signal reception parameter value and an uplink channel quality parameter value at a location of the terminal according to the interaction information;

[0052] According to the obtained cell quality parameter value, updating the corresponding cell quality parameter in the cell channel quality statistics table of the cell includes:

[0053] A target reference signal reception parameter interval to which the reference signal reception parameter value belongs is determined, and an uplink channel quality parameter corresponding to the target reference signal reception parameter interval is updated according to the uplink channel quality parameter value.

[0054] In addition, it should be understood that the reference signal reception parameter in this embodiment may include at least one of various parameters that can characterize the cell quality, and may be flexibly set according to the application scenario requirements. For example, in one example, the reference signal reception parameter may include but is not limited to at least one of a reference signal received power (RSRP) and a reference signal received quality (RSRQ).

[0055] For ease of understanding, this embodiment is described below by taking the correspondence between several reference signal reception parameters and uplink channel quality parameters as examples.

[0056] For example, in one example, the reference signal reception parameter includes the reference signal reception power, and the uplink channel quality parameter includes the single resource block signal-to-noise ratio and the uplink block error rate (of course, it may also include only one of the single resource block signal-to-noise ratio and the uplink block error rate). Figure 2As shown, in this example, the interval length of the reference signal received power value is set to 10db, and of course it can be any value between 1db and 15db. The specific value of the interval length can be flexibly set according to specific needs. In this example, the reference signal received power value, the single resource block signal-to-noise ratio value and the uplink block error rate value can be obtained based on the interactive information between the terminal, and the reference signal received power value obtained is determined in Figure 2 Which reference signal received power interval does it belong to (for example, assuming it belongs to the interval of -64dBm to -54dBm), and then according to the obtained single resource block signal-to-interference ratio and uplink block error rate value, Figure 2 The values ​​of the single resource block signal-to-noise ratio and uplink block error rate corresponding to the reference signal receiving power range of -64dBm to -54dBm are updated.

[0057] For another example, the reference signal reception parameter includes the reference signal reception quality, and the uplink channel quality parameter includes the single resource block signal-to-noise ratio and the uplink block error rate (of course, it may also include only one of the single resource block signal-to-noise ratio and the uplink block error rate). Figure 3 As shown, in this example, the interval length of the reference signal reception quality is set to 3, and of course it can be any value between 1 and 5. The specific value of the interval length can be flexibly set according to specific needs. In this example, the reference signal reception quality, the single resource block signal-to-interference ratio value and the uplink block error rate value can be obtained based on the interactive information between the terminal, and the reference signal reception power value obtained is determined in Figure 3 Which reference signal reception quality interval does it belong to (for example, assuming it belongs to the interval of -9 to -6), and then according to the obtained single resource block signal-to-interference ratio and uplink block error rate value, Figure 3 The values ​​of the single resource block signal-to-interference ratio and the uplink block error rate corresponding to the reference signal reception quality interval of -9 to -6 are updated.

[0058] In other application scenarios of this embodiment, in order to further improve the requirements of cell switching or redirection, other corresponding quality parameters can be further flexibly added to the cell quality parameters in the cell channel quality statistics table. For example, the cell quality parameters also include the downlink channel quality parameters of the cell (and may optionally include at least one of the quality parameters of the downlink control channel and the downlink service channel); the cell channel quality statistics table includes downlink channel quality parameters corresponding to reference signal reception parameters with values ​​in different intervals; and it should be understood that the downlink channel quality parameters in this embodiment may include at least one of the various parameters that can reflect the downlink channel quality. For example, the downlink channel quality parameters may include but are not limited to at least one of the modulation and coding scheme (MCS), downlink block error rate and channel quality indicator (CQI).

[0059] In this application scenario, obtaining the cell quality parameter of the cell according to the interaction information also includes obtaining a downlink channel quality parameter value;

[0060] According to the obtained cell quality parameter value, updating the corresponding cell quality parameter in the cell channel quality statistics table of the cell may also include: determining a target reference signal reception parameter interval to which the reference signal reception parameter value belongs, and updating the downlink channel quality parameter corresponding to the target reference signal reception parameter interval according to the downlink channel quality parameter value.

[0061] For ease of understanding, this embodiment is described below by taking the correspondence between several reference signal reception parameters, uplink channel quality parameters, and downlink channel quality parameters as examples.

[0062] For example, in one example, the reference signal reception parameter includes the reference signal reception power, the uplink channel quality parameter includes the single resource block signal-to-noise ratio and the uplink block error rate (of course, it can also include only one of the single resource block signal-to-noise ratio and the uplink block error rate), and the downlink channel quality parameter can include but is not limited to the modulation and coding strategy, the downlink block error rate and the CQI (of course, it can also include only one of the modulation and coding strategy, the downlink block error rate and the CQI). Please refer to Figure 4 As shown, in this example, the interval length of the reference signal received power value is set to 15db, and of course it can be any value between 1db and 15db. The specific value of the interval length can be flexibly set according to specific needs. In this example, the reference signal received power value, the signal-to-noise ratio of a single resource block, the uplink block error rate value, the modulation and coding strategy and the downlink block error rate can be obtained based on the interactive information between the terminal, and the obtained reference signal received power value is determined in Figure 4Which reference signal received power interval does it belong to (for example, assuming it belongs to the interval of -64dBm to -49dBm), and then according to the obtained single resource block signal-to-noise ratio value, uplink block error rate value, modulation and coding strategy value and downlink block error rate value, Figure 4 The single resource block signal-to-noise ratio, uplink block error rate value, modulation and coding strategy and downlink block error rate corresponding to the reference signal receiving power range of -64dBm to -49dBm are updated.

[0063] For another example, in one example, the reference signal reception parameter includes the reference signal reception quality, the uplink channel quality parameter includes the single resource block signal-to-noise ratio and the uplink block error rate (of course, it can also include only any one of the single resource block signal-to-noise ratio and the uplink block error rate), and the downlink channel quality parameter can include but is not limited to the modulation and coding strategy, the downlink block error rate and the CQI (of course, it can also include only any one of the modulation and coding strategy, the downlink block error rate and the CQI). Please refer to Figure 5 As shown, in this example, the interval length of the reference signal reception quality value is set to 3, and of course it can be any value between 1 and 6. The specific value of the interval length can be flexibly set according to specific needs. In this example, the reference signal reception quality value, the signal-to-noise ratio of a single resource block, the uplink block error rate value, the modulation and coding strategy, and the downlink block error rate can be obtained based on the interactive information between the terminal, and the obtained reference signal reception quality value is determined in Figure 5 Which reference signal reception quality interval does it belong to (for example, assuming it belongs to the interval of -6 to -3), and then according to the obtained single resource block signal-to-interference ratio value, uplink block error rate value, modulation and coding strategy value and downlink block error rate value, Figure 5 The single resource block signal-to-interference ratio, uplink block error rate, modulation and coding strategy and downlink block error rate corresponding to the reference signal reception quality interval of -6 to -3 are updated.

[0064] In some application scenarios of this embodiment, in order to avoid that the downlink channel quality parameters and / or uplink channel quality parameters corresponding to certain reference signal reception parameter intervals cannot be updated because the corresponding interaction information has not been obtained, and to improve the comprehensiveness, accuracy and efficiency of the update. Optionally, in some application scenarios, according to the obtained cell quality parameter value, the corresponding cell quality parameter update in the cell channel quality statistics table of the cell also includes at least one of the following:

[0065] According to the target reference signal receiving parameter interval (such as the above Figure 2estimating a change value of an uplink channel quality parameter corresponding to at least one other reference signal reception parameter interval (for example, including but not limited to at least one of a single resource block signal-to-interference ratio and an uplink block error rate), and updating the uplink channel quality parameter corresponding to at least one other reference signal reception parameter interval according to the obtained change value;

[0066] According to the difference between the value before and after the update of the downlink channel quality parameter corresponding to the target reference signal reception parameter interval, estimate the change value of the downlink channel quality parameter corresponding to at least one other reference signal reception parameter interval (for example, including but not limited to at least one of the modulation and coding strategy and the downlink block error rate), and update the downlink channel quality parameter corresponding to at least one other reference signal reception parameter interval according to the obtained change value.

[0067] That is, in this embodiment, the values ​​of the uplink channel quality parameter and the downlink channel quality parameter corresponding to other reference signal reception parameter intervals can be corrected according to the difference between the value before the update and the value after the update of the uplink channel quality parameter corresponding to the target reference signal reception parameter interval and the difference between the value before the update and the value after the update of the downlink channel quality parameter. And it should be understood that the above estimation method in this embodiment can be flexibly adopted based on the association relationship between the above parameters.

[0068] It should be understood that in this embodiment, the cell channel quality statistics table of each cell can be established once each cell is successfully established, and can be stored in the cell quality summary database. In this embodiment, when the cell is initially established and the cell channel quality statistics table is initially established, an initial cell channel quality statistics table of the cell can be formed by calculation based on the cell index (NI value, etc.). Once the cell is established, the cell starts to collect the channel quality information of the cell, and it can be executed as long as the corresponding interactive information can be interacted with the terminal. Based on the information interaction with the terminal, the corresponding relationship between the reference signal received power value (or reference signal received quality) at the location of the terminal and the uplink channel quality and downlink channel quality can be evaluated, and then the cell channel quality statistics table of the cell is updated accordingly, and the uplink channel quality parameters and downlink channel quality parameters corresponding to other reference signal received power intervals in the cell channel quality statistics table are corrected according to the uplink channel quality and downlink channel quality corresponding to the reference signal received power of the terminal, so that the values ​​of the corresponding channel quality parameters in the cell channel quality statistics table in the cell are more inclined to the actual performance of the cell channel.

[0069] Therefore, in some examples of the present embodiment, the principle for updating the channel quality parameters in the cell channel quality statistics table is: for the channel quality parameters corresponding to each interval of the reference signal reception parameter, if the corresponding channel quality parameter value is obtained according to the corresponding interactive information obtained from the terminal, the obtained channel quality parameter value shall prevail; for the corresponding channel quality parameter value not obtained according to the corresponding interactive information obtained from the terminal, the channel quality parameter adjustment direction or adjustment value estimated according to the channel quality parameter value obtained from the interactive information shall be used as the basis for correction.

[0070] In addition, it should be understood that the change of the channel quality of the cell may be periodic. For example, for some cells, the change of its channel quality may conform to a change cycle of one week (some cells may be one day or one month, etc.); at this time, when the channel quality statistics are performed for the cell, periodic statistics can be performed, and after the periodic statistical results are stable, the corresponding values ​​of the corresponding parameters in the corresponding cell channel quality statistics table in this period will basically be counted and the value changes at the corresponding moments in different periods will not fluctuate much. Therefore, optionally, in this embodiment, the communication device can store the cell channel quality statistics table it has counted in the background cell quality summary database after determining that it is stable.

[0071] In addition, in some examples of the present embodiment, for a certain cell, the cell channel quality corresponding to different time periods within a cycle may also be relatively stable. For example, on a certain day of a certain month of a certain year, the parameter value corresponding to the cell channel quality of a certain cell from 00:00 to 6:00 may be a stable state, and the parameter value corresponding to the cell channel quality from 6:00 to 18:00 may be another stable state; the parameter value corresponding to the cell channel quality from 18:00 to 00:00 may be another stable state; in view of this situation, optionally, in some examples of the present embodiment, a cell channel quality statistics table of a cell may be set to include multiple time periods, and each time period may correspond to the uplink channel quality parameters and downlink channel quality parameters corresponding to the reference signal reception parameters with values ​​in different intervals;

[0072] In this example, after the interaction information is obtained, the current time is also obtained; and according to the obtained cell quality parameter value, the corresponding cell quality parameter in the cell channel quality statistics table of the cell is updated, including:

[0073] The target time period corresponding to the current time is determined in the cell channel quality statistics table, and the cell quality parameter corresponding to the target time period is updated according to the obtained cell quality parameter value.

[0074] For example, see Figure 6As shown, in one example, two time periods (the number of time periods and the values ​​of each time period can be flexibly set according to specific needs) correspond to a set of reference signal reception parameters, uplink channel quality parameters and downlink channel quality parameters respectively; the reference signal reception parameters include the reference signal reception power, the uplink channel quality parameters include the single resource block signal-to-noise ratio and the uplink block error rate (of course, it can also include only one of the single resource block signal-to-noise ratio and the uplink block error rate), and the downlink channel quality parameters can include but are not limited to the modulation and coding strategy and the downlink block error rate (of course, it can also include only one of the modulation and coding strategy and the downlink block error rate). Please refer to Figure 6 As shown, in this example, the interval length of the reference signal receiving power value is set to 15db, and of course it can also be any value between 1db and 15db. The specific value of the interval length can be flexibly set according to specific needs. In this example, the reference signal receiving power value, the signal-to-noise ratio of a single resource block, the uplink block error rate value, the modulation and coding strategy and the downlink block error rate can be obtained based on the interactive information between the terminal, and it also includes obtaining the current time; and determining which time period the obtained current time belongs to (for example, assuming it is the first time period), and which reference signal receiving power interval the obtained reference signal receiving power value belongs to in the time period (for example, assuming it belongs to the interval of -64dBm to -49dBm), and then according to the obtained single resource block signal-to-noise ratio, the uplink block error rate value, the modulation and coding strategy value and the downlink block error rate value, Figure 6 The single resource block signal-to-noise ratio, uplink block error rate value, modulation and coding strategy and downlink block error rate corresponding to the reference signal receiving power range of -64dBm to -49dBm are updated.

[0075] In this embodiment, the cell channel quality statistics table of the cell is saved in a background management device (such as a background gateway device), and can be directly loaded from the background management device when the cell is restarted (optionally, in addition to loading the cell channel quality statistics table of this area, the cell channel quality statistics table of at least one neighboring area of ​​this cell can also be loaded), which can not only reduce the statistical time (that is, the learning time), but also improve the acquisition efficiency.

[0076] In some examples of this embodiment, the cell may be required to save the cell channel quality statistics table to the background at the initial stage according to the preset time interval (for example, 20 minutes), and then update the cell channel quality statistics table at a certain interval. This behavior is saved until the channel quality is stable. After the cell is restarted, it can be loaded directly from the background. And the cell can be continuously detected to update the cell channel quality statistics table until the channel is stable. And after detecting that the channel is stable, it can no longer be monitored or the detection frequency can be reduced according to the needs, or it can continue to be monitored according to the original detection strategy.

[0077] In this way, each cell can perform statistics (or learn) and store the cell channel quality of each cell based on the cell channel quality acquisition method of the above example, and store it for retrieval.

[0078] For example, in some application scenarios of the present embodiment, for a certain cell, in addition to statistics on the cell channel quality of the cell through the above-mentioned example method, the unique identification information of the neighboring cells of the cell can also be obtained; the cell channel quality statistics table of the neighboring cells is retrieved from the cell quality summary database according to the unique identification information of the neighboring cells obtained. For example, in one application scenario, after the current cell is running, according to the configured neighboring cell information, the cell channel quality statistics table of the neighboring cells is requested from the neighboring cells. If the current cell is an initial operation cell, it is recommended to delay 10 to 20 minutes after the current cell is normal, and then obtain the cell channel quality statistics table from the neighboring cells or query the background for the cell channel quality statistics table of the neighboring cells. In some examples of the present embodiment, if the current cell fails to obtain a certain neighboring cell summary table, it can randomly initiate the acquisition process again at an interval of n*20 (can also be set to other values) minutes (1≤n≤4).

[0079] In some application scenarios of this embodiment, the method for acquiring cell channel quality further includes at least one of the following:

[0080] When the current cell receives a notification message about a change in the channel quality of a neighboring cell, it can re-acquire the cell channel quality statistics table of the target neighboring cell corresponding to the notification message about the change in the channel quality of the neighboring cell. In one example, it can directly obtain the changed parameters of the target neighboring cell, and make corresponding updates to the changed parameters in the cell channel quality statistics table corresponding to the target neighboring cell that has been obtained.

[0081] Accordingly, in an application scenario of the present embodiment, after the corresponding cell quality parameter in the cell channel quality statistics table of the cell is updated, a neighboring cell channel quality change notification message may be sent to each serving cell that uses the cell as a neighboring cell.

[0082] Optionally, in this embodiment, before retrieving the cell channel quality statistics table of the neighboring area from the cell quality summary database according to the unique identification information of the neighboring area, in order to avoid conflicts between the cell quality statistics or query process and related operations such as service execution in the cell, at least one of the following may also be included:

[0083] Determine the time to call the cell channel quality statistics table. When the time to call the cell channel quality statistics table arrives, retrieve the cell channel quality statistics table of the neighboring area from the cell quality summary database according to the unique identification information of the neighboring area. The method for determining the time to call the cell channel quality statistics table can be determined based on at least one of the business situation of the cell, business change trend, channel quality change trend, etc. In one example, the time to call the cell channel quality statistics table can be determined by adopting the principle of advancing the relatively predicted conflict time point (that is), and in one example, the principle of delaying the relatively predicted conflict time point can also be adopted.

[0084] Before updating the corresponding cell quality parameter in the cell channel quality statistics table of the cell according to the obtained cell quality parameter value, the method further includes: determining the update time of the cell channel quality statistics table, and when the update time of the cell channel quality statistics table arrives, updating the corresponding cell quality parameter in the cell channel quality statistics table of the cell according to the obtained cell quality parameter value. The method for determining the update time of the cell channel quality statistics table can also be determined based on at least one of the business situation of the cell, the business change trend, the channel quality change trend, etc. In one example, the update time of the cell channel quality statistics table can also adopt the principle of advancing the relative predicted conflict time point (that is,), and in another example, the principle of lagging the relative predicted conflict time point can also be adopted.

[0085] In addition, it should be understood that when the cell channel quality statistics table of the neighboring cell is used for scheduling, if there is a time period interval in the cell channel quality statistics table, it is necessary to pay attention to calling the channel quality parameters of the corresponding time period; when the cell channel quality statistics table of the neighboring cell is used for scheduling, attention should be paid to the correspondence between the reference signal receiving power, which should be the same as the reference signal receiving power of the current cell or based on the neighboring cell reference signal receiving power reported by the terminal, that is, the uplink and downlink channel quality corresponding to the neighboring cell reference signal receiving power index, and then compared with the channel quality of the current service of this cell.

[0086] In this embodiment, for the application scenario where a cell has a large number of neighboring cells, when the cell scheduling uses the neighboring cell channel quality statistics table, if the decision on cell switching is already being made, that is, the neighboring cell channel conditions have been determined in advance, and re-acquisition is no longer allowed in time, even if the neighboring cell notifies the message that the channel quality has changed, the cell can keep this message and continue to execute the current scheduling, and update the neighboring cell channel quality statistics table after the current scheduling is completed, so as to make basic reserves for the next quality switching. As time goes by, the characteristics of the network will tend to be stable, and the channel quality changes will tend to be stable, so this temporary change event will become less and less.

[0087] After the cell is restarted, the cell can directly load the channel quality information of the neighboring cells that are suitable for the current day. Subsequently, the cell will load the channel quality conditions of the neighboring cells of the current day from the background as needed every day. Of course, it can also be loaded at an hourly granularity or a smaller granularity. The specific implementation strategy can be determined based on multiple conditions such as network pressure, server pressure, base station pressure, network pressure, etc., and the best implementation strategy can be selected.

[0088] In the event of a failure in requesting the channel quality statistics table of a neighboring cell, the communication device may preferentially switch to the cell containing the channel quality. If the channel quality statistics tables of all neighboring cells are not obtained, the communication device may initiate a blind inter-frequency quality handover - that is, blindly switch the UE to an inter-frequency cell.

[0089] In addition, in this embodiment, considering various situations such as newly built cells and cell restart, the cell channel quality statistics tables of all cells are saved by the background, and the communication equipment (such as base station) can directly obtain them from the background after operation, which not only ensures the acquisition of the channel quality information of the neighboring cells, but also ensures that the channel summary table information is not lost after the base station is powered off. This means that there is no need to start a new learning process from scratch after power failure, so the real-time performance can be further improved.

[0090] At the same time, in this embodiment, after a period of learning, the channel quality of the cells in the network is basically stabilized. As time goes by, the probability of the communication device needing to learn will become lower and lower. Then, after the operation of the cell, the cell channel quality statistics table information of the cell and the neighboring cell can be loaded into the communication device (such as a base station) together, so that the channel quality information can be used without delay as long as the cell is running. That is, once the cell channel quality statistics table that meets the requirements of a certain time period is loaded, the base station scheduling can be used directly without further learning, thereby meeting the real-time requirements of the service for channel quality.

[0091] Embodiment 2:

[0092] This embodiment also provides a cell channel quality acquisition device, which can be set in a communication device on the network side (such as a base station), see Figure 7 As shown, including:

[0093] The information acquisition module 701 is used to acquire the interaction information with the terminal in the cell. For the specific interaction information and the acquisition process, please refer to the above embodiment, which will not be described in detail here.

[0094] The parameter value acquisition module 702 is used to acquire the cell quality parameter value of the cell according to the interaction information. The specific acquisition process and the specific contents of the cell quality parameter value are shown in the above embodiment and will not be repeated here.

[0095] The update processing module 703 is used to update the corresponding cell quality parameter in the cell channel quality statistics table of the cell according to the obtained cell quality parameter value, the cell quality parameter includes the uplink channel quality parameter of the cell, and the cell channel quality statistics table includes the unique identification information of the cell. The specific update process is also shown in the above embodiment, which will not be repeated here.

[0096] The management module 704 is used to store the updated cell channel quality statistics table into the cell quality summary database for retrieval.

[0097] For ease of understanding, this embodiment is described below with reference to the application of the above-mentioned cell channel quality acquisition device as an example. In this example, it includes the following process:

[0098] The content that needs to be included in the cell channel quality statistics table can be determined by the background or communication equipment, and when determined by the background, the determined content of the cell channel quality statistics table can also be sent to the cell channel quality acquisition device. The cell channel quality acquisition device generates a cell channel quality statistics table for the established cell when the cell is established according to the content that needs to be included in the received cell channel quality statistics table, and stores the cell channel quality statistics table in the background. Once the cell channel quality acquisition device finds that the cell channel quality statistics table of a certain cell needs to be updated, its update processing module 703 performs corresponding updates and stores the updated cell channel quality statistics table in the background. The cell channel quality acquisition device can also load and call the cell channel quality statistics table of the serving cell and the neighboring area of ​​the serving cell from the background. For the specific loading and calling process, please refer to the above embodiments, which will not be repeated here. The cell channel quality statistics table of the serving cell and its neighboring cells maintained and called by the cell channel quality acquisition device includes the cell uplink channel quality parameter value, so that when the cell channel quality is needed as a basis for cell switching or redirection, the cell uplink channel quality can be selectively used as a basis according to demand, so that the basis selection for operations such as cell switching or redirection is larger and more flexible, the operation results are more accurate, the wireless network switching success rate and the wireless network service perception capability are improved, and the utilization efficiency of the wireless network and the user experience satisfaction can also be improved.

[0099] For ease of understanding, the present embodiment hereinafter illustrates an example of a process in which a cell channel quality acquisition device acquires cell channel quality in conjunction with a specific application scenario. Figure 8 As shown, including:

[0100] S801: Initialization of cell channel quality statistics table: Once a cell is established, the cell channel quality statistics table generating device can calculate and form a cell channel quality statistics table of the cell according to the cell index (NI value, etc.). In some application scenarios, an empty cell channel quality statistics table can be generated according to the demand.

[0101] S802: Collecting channel quality information of the cell: Once the cell is established, the cell starts to collect channel quality information of the cell, which can be obtained, for example, through interaction information between the terminal and the base station.

[0102] S803: Determine whether the cell channel quality statistics table needs to be updated. If so, go to S804; otherwise, go to S802.

[0103] S804: Update the cell channel quality statistics table.

[0104] For example, the base station obtains the reference signal received power value (RSRP / RSRQ) of the location of the terminal based on the information exchange between the terminal and the base station. Based on the uplink and downlink channel quality information (the stable channel quality information of this scheduling), the base station modifies the comparison relationship table of time, RSRP and channel quality in the local channel quality summary table, completes the mapping task of the corresponding relationship, and completes the revision of the channel quality statistics table of this cell. If the channel quality statistics table of the cell has been shared with the cell quality summary database, the base station determines whether it needs to be shared with the cell quality summary database. If necessary, the synchronization work of the cell quality summary database is completed. The base station cell often studies and revises for a long time, so that the cell channel quality statistics table is more inclined to the actual performance of the cell channel. The cell constantly studies and revises in different time periods, and the channel quality data in the cell channel quality statistics table of this cell is stabilized, so that the cell channel quality statistics table of this cell is closer to the actual situation, and the cell also completes the mapping of the corresponding relationship between channel quality and RSRP / RSRQ and time.

[0106] This embodiment also provides a communication device, which may be a user-side device, such as various user-side user devices (such as user terminals), or a network-side communication device, such as a base station device).

[0112] In addition, it should be understood that the base station in this embodiment may also adopt a CU (Central Unint, central unit) -DU (Distributed Unit, distributed unit) architecture, where DU is a distributed access point, responsible for completing the underlying baseband protocol and radio frequency processing functions, and CU is a central unit, responsible for processing high-level protocol functions and centrally managing multiple DUs.
