Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment is as follows:

the method aims at the problem that only the downlink channel quality of a cell can be used as a basis in the processes of switching or redirection and the like because a base station only pays attention to the downlink channel quality related information of the cell when the base station performs cell quality statistics in the related technology. In the cell quality statistics process, the cell channel quality acquisition method provided by this embodiment may set a cell channel quality statistics table for a cell to be counted, where the cell channel quality statistics table includes a cell quality parameter to be counted and unique identification information of the cell, so that one cell uniquely corresponds to one cell channel quality statistics table; and in the set cell channel quality statistical table, the cell quality parameters comprise uplink channel quality parameters of the cell, when the cell quality parameters are counted, the cell quality parameter values of the cell can be obtained based on interactive information obtained by interacting with the terminal, and the corresponding cell quality parameters in the cell channel quality statistical table of the cell are updated and then stored in a cell quality summary database for calling, so that when the cell channel quality is required to be used as the basis for cell switching or redirection and the like, the uplink channel quality of the cell can be selectively used as the basis according to the demand, the basis selection surface of operations such as cell switching or redirection and the like is larger and more flexible, the operation result is more accurate, and the user experience satisfaction can be further improved.

It should be understood that, in this embodiment, it is not limited that the cell channel quality statistics table set for all cells requiring cell quality statistics must include uplink channel quality parameters; in some application scenarios, when quality statistics can be selectively performed on some or some class of cells, statistics on uplink channel quality of the cells is required to be set, and statistics on uplink channel quality of other cells can be selectively not performed; in other application scenarios, uplink channel quality statistics can be selectively performed for all cells needing quality statistics; which mode can be flexibly selected according to the requirement is particularly adopted. It should be understood that, in some application scenarios, the content included in the generated cell channel quality statistics table may be the same or different for all cells to be subjected to quality statistics; for example, the same cell quality parameters may 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 may not be updated correspondingly. In this embodiment, the statistical uplink channel quality parameter may include at least one of quality parameters of an uplink control channel and an uplink traffic channel.

For convenience of understanding, the following description of the present embodiment, with reference to the cell channel quality acquiring method shown in fig. 1 as an example, includes:

s101: and acquiring the interaction information between the terminal and the cell.

In this step, the communication device acquires the interaction information with the terminal in the cell, and the communication device may be, but is not limited to, a base station device on the network side, and may also 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 be changed in the subsequent communication network as long as it is an equivalent device that realizes the function of the corresponding base station.

It should be understood that the interaction information with the terminal in this embodiment may be any message carrying information capable of characterizing the channel quality of the cell. The interactive information may be related information directly carrying a cell quality parameter value, or may also be related information carrying a cell quality parameter value for determining, or related information determining a cell quality parameter value according to a receiving condition of the interactive information; such as packet loss rate, reception accuracy rate (or error rate), etc.

It should be understood that, in the embodiment, when performing the cell quality statistics, the statistics is not limited to be performed only according to the interaction information between the terminal and the cell, and the corresponding statistics may also be performed according to the channel quality information, which is obtained from other network devices and can represent the cell, as needed.

S102: and acquiring the cell quality parameter value of the cell according to the interaction information.

In this embodiment, when the interactive information directly carries the 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 carry out corresponding calculation to obtain the corresponding cell quality parameter value. When the cell quality parameter value is determined according to the receiving condition of the interactive information, corresponding statistics can be carried out on the receiving condition of the interactive information, and the corresponding cell quality parameter value is calculated by adopting a corresponding algorithm according to the statistical result.

S103: and updating the corresponding cell quality parameters in a cell channel quality statistical table of the cell according to the acquired cell quality parameter values, wherein the cell quality parameters comprise uplink channel quality parameters of the cell, and the cell channel quality statistical table comprises the unique identification information of the cell.

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

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 to Interference Noise Ratio (single rb SINR) and an uplink Block error rate (bler).

The unique identification information of the cell in this embodiment may be any information that can uniquely characterize the cell, for example, in an 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 is different between cells of different base stations, the unique identification information of the cell may also include only the cell identification information.

S104: and storing the updated cell channel quality statistical table into a cell quality summarizing database for calling.

In this embodiment, the cell quality summarizing database may store a cell channel quality statistics table of each cell for which quality statistics is required; it can also be used to store the cell channel quality statistics table of the specified part of the cells that need to be quality-counted. In this embodiment, the cell quality summarizing database may be disposed on the communication device, or may be disposed on a background management device of the communication device. For example, when the communication device is a base station, the communication device may be disposed on a background management device of the base station. Therefore, when needed, a cell channel quality statistical table of the corresponding cell can be called from the cell quality summarizing database according to the requirements; and the called cell channel quality statistical table comprises uplink channel quality parameters used for representing the cell uplink channel quality, and compared with the situation that only the cell downlink channel quality related information is concerned when a base station performs cell quality statistics in the related technology, the cell uplink channel quality can be selectively used as the basis according to the requirement under the condition that only the cell downlink channel quality can be used as the basis in the switching or redirection process, so that the basis selection surface of the cell switching or redirection operation is larger and more flexible, the operation result is 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 can also be improved.

Optionally, in this embodiment, the cell quality parameters in the cell channel quality statistics table may be set according to requirements to only include uplink channel quality parameters that characterize uplink channel quality of the cell. In other examples of this embodiment, in order to further improve the requirements of cell handover or redirection, corresponding other quality parameters may be flexibly added to the cell quality parameters in the cell channel quality statistics table.

For example, in an application scenario of the present embodiment, the cell quality parameters further include a Reference Signal receiving parameter; if necessary, the channel quality statistical table of the corresponding cell can be directly called, and the value of the reference signal receiving parameter of the cell is extracted from the channel quality statistical table of the cell. In some examples, the cell quality parameter and the uplink channel quality parameter of the cell may be separately and independently counted and independently invoked upon subsequent invocation. In some examples of this embodiment, in order to improve efficiency and accuracy, statistics may be further associated between the reference signal reception parameter of the cell and the uplink channel quality parameter. At this time, the cell channel quality statistical table of the cell comprises uplink channel quality parameters corresponding to the reference signal receiving parameters of different interval values. In this embodiment, the interval value of the reference signal receiving parameter can be flexibly set according to the requirement, and the lengths of different intervals can be the same or different.

In this example, obtaining the cell quality parameter value of the cell according to the mutual information includes:

acquiring a reference signal receiving parameter value of the position of the terminal and an uplink channel quality parameter value according to the interactive information;

according to the acquired cell quality parameter value, updating the corresponding cell quality parameter in the cell channel quality statistical table of the cell comprises:

and determining a target reference signal receiving parameter interval to which the reference signal receiving parameter value belongs, and updating the uplink channel quality parameter corresponding to the target reference signal receiving parameter interval according to the uplink channel quality parameter value.

In addition, it should be understood that the reference signal receiving 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 Received parameter may include, but is not limited to, at least one of Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ).

For convenience of understanding, in the present embodiment, several corresponding relationships between the reference signal receiving parameters and the uplink channel quality parameters are taken as examples for description.

For example, in one example, the reference signal reception parameter includes a reference signal reception power, and the uplink channel quality parameter includes a single resource block signal-to-interference ratio and an uplink block error rate (of course, only either one of the single resource block signal-to-interference ratio and the uplink block error rate may be included). Referring to fig. 2, in this example, the length of the interval for which the reference signal received power is set to be 10db, but may be any value between 1db and 15 db. The specific value of the interval length can be flexibly set according to specific requirements. In this example, the reference signal received power value, the single resource block signal-to-interference ratio value, and the uplink block error rate value may be obtained based on the mutual information with the terminal, and it is determined to which reference signal received power interval in fig. 2 the obtained reference signal received power value belongs (for example, it is assumed that the reference signal received power interval belongs to an interval of-64 dBm to-54 dBm), and then values of the single resource block signal-to-interference ratio and the uplink block error rate corresponding to the reference signal received power interval of-64 dBm to-54 dBm in fig. 2 are updated according to the obtained single resource block signal-to-interference ratio and the uplink block error rate value.

For another example, in another example, the reference signal reception parameter includes a reference signal reception quality, and the uplink channel quality parameter includes a single resource block signal-to-interference ratio and an uplink block error rate (of course, only either one of the single resource block signal-to-interference ratio and the uplink block error rate may be included). Referring to fig. 3, in the present example, the length of the interval for setting the reference signal received quality is 3, but may be any value between 1 and 5. The specific value of the interval length can be flexibly set according to specific requirements. In this example, the reference signal reception quality, the single resource block signal-to-interference ratio and the uplink block error rate value may be obtained based on the mutual information with the terminal, and it is determined to which reference signal reception quality interval the obtained reference signal reception power value belongs in fig. 3 (for example, it is assumed that the reference signal reception quality interval belongs to an interval of-9 to-6), and then 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 in fig. 3 are updated according to the obtained single resource block signal-to-interference ratio and the uplink block error rate value.

In other application scenarios of this embodiment, in order to further improve requirements of cell handover or redirection, corresponding other quality parameters may be further flexibly added to the cell quality parameters in the cell channel quality statistics table. For example, the cell quality parameter further includes a downlink channel quality parameter of the cell (and optionally may include at least one of a quality parameter of a downlink control channel and a quality parameter of a downlink traffic channel); the cell channel quality statistical table comprises downlink channel quality parameters corresponding to reference signal receiving parameters with different interval values; and it should be understood that the downlink channel quality parameter in this embodiment may include at least one of various parameters reflecting the downlink channel quality. For example, the downlink Channel Quality parameter may include, but is not limited to, at least one of a Modulation and Coding Scheme (MCS), a downlink block error rate (bler), and a Channel Quality Indicator (CQI).

Under the application scene, acquiring the cell quality parameter of the cell according to the interaction information, and acquiring a downlink channel quality parameter value;

according to the obtained cell quality parameter value, updating the corresponding cell quality parameter in the cell channel quality statistical table of the cell may further include: and determining a target reference signal receiving parameter interval to which the reference signal receiving parameter value belongs, and updating the downlink channel quality parameter corresponding to the target reference signal receiving parameter interval according to the downlink channel quality parameter value.

For convenience of understanding, in the present embodiment, several corresponding relationships among the reference signal receiving parameters, the uplink channel quality parameters, and the downlink channel quality parameters are taken as examples for description.

For example, in one example, the reference signal received parameter includes a reference signal received power, the uplink channel quality parameter includes a single resource block signal-to-interference ratio and an uplink block error rate (of course, only any one of the single resource block signal-to-interference ratio and the uplink block error rate may be included), and the downlink channel quality parameter may include, but is not limited to, a modulation and coding strategy, a downlink block error rate, and a CQI (of course, only any one of the modulation and coding strategy, the downlink block error rate, and the CQI may be included). Referring to fig. 4, in this example, the length of the interval for which the reference signal received power is set to be 15db, but may be any value between 1db and 15 db. The specific value of the interval length can be flexibly set according to specific requirements. In this example, the reference signal received power value, the single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy, and the downlink block error rate may be obtained based on the mutual information with the terminal, and it is determined which reference signal received power interval (for example, assumed to belong to an interval of-64 dBm to-49 dBm) the obtained reference signal received power value belongs to in fig. 4, and then the single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy value, and the downlink block error rate corresponding to the reference signal received power interval of-64 dBm to-49 dBm in fig. 4 are updated according to the obtained single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy, and the downlink block error rate.

For another example, in one example, the reference signal reception parameter includes a reference signal reception quality, the uplink channel quality parameter includes a single resource block signal-to-interference ratio and an uplink block error rate (of course, only any one of the single resource block signal-to-interference ratio and the uplink block error rate may be included), and the downlink channel quality parameter may include, but is not limited to, a modulation and coding strategy, a downlink block error rate, and a CQI (of course, only any one of the modulation and coding strategy, the downlink block error rate, and the CQI may be included). Referring to fig. 5, in this example, the length of the interval for which the reference signal received quality value is set to be 3, but may be any value between 1 and 6. The specific value of the interval length can be flexibly set according to specific requirements. In this example, the reference signal reception quality value, the single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy, and the downlink block error rate may be obtained based on the mutual information with the terminal, and it is determined to which reference signal reception quality interval (for example, assumed to belong to an interval of-6 to-3) the obtained reference signal reception quality value belongs in fig. 5, and then the values of the single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy value, and the downlink block error rate corresponding to the reference signal reception quality interval of-6 to-3 in fig. 5, the uplink block error rate value, the modulation and coding strategy, and the downlink block error rate may be updated according to the obtained single resource block signal-to-interference ratio, the uplink block error rate value, the modulation and coding strategy, and the downlink block.

In some application scenarios of this embodiment, in order to avoid that the downlink channel quality parameters and/or the uplink channel quality parameters corresponding to some reference signal receiving parameter intervals cannot be updated all the time because corresponding interaction information is acquired all the time, the comprehensiveness, the accuracy rate, and the efficiency of updating are improved. Optionally, in some application scenarios, updating the corresponding cell quality parameter in the cell channel quality statistics table of the cell according to the obtained cell quality parameter value further includes at least one of the following:

estimating a variation value (for example, but not limited to, at least one of a single resource block signal-to-interference ratio and an uplink block error rate) of an uplink channel quality parameter corresponding to at least one other reference signal reception parameter interval according to a difference between a value before updating and a value after updating of the uplink channel quality parameter corresponding to a target reference signal reception parameter interval (for example, an interval of-64 dBm to-54 dBm in fig. 2, or an interval of-3-9 to-6 in the drawing), and updating the uplink channel quality parameter corresponding to at least one other reference signal reception parameter interval according to the obtained variation value;

estimating a variation value of a downlink channel quality parameter (which may include, but is not limited to, at least one of a modulation and coding strategy and a downlink block error rate) corresponding to at least one other reference signal reception parameter interval according to a difference between a pre-update value and an updated value of the downlink channel quality parameter corresponding to the target reference signal reception parameter interval, and updating the downlink channel quality parameter corresponding to the at least one other reference signal reception parameter interval according to the obtained variation value.

That is, in this embodiment, the values of the uplink channel quality parameter and the downlink channel quality parameter corresponding to the other reference signal receiving parameter intervals may be corrected according to the difference between the value before updating and the value after updating of the uplink channel quality parameter corresponding to the target reference signal receiving parameter interval and the difference between the value before updating and the value after updating of the downlink channel quality parameter. And it should be understood that the above estimation manner in the present embodiment can be flexibly adopted based on the correlation between the above parameters.

It should be understood that, in this embodiment, the cell channel quality statistics table for each cell may be established once each cell is successfully established, and may be stored in the cell quality summary database. In this embodiment, when initially establishing a cell and initially establishing a cell channel quality statistical table, an initial cell channel quality statistical table of a local cell may be formed by calculation based on cell indexes (NI values, etc.). Once a cell is established, the cell starts to collect channel quality information of the cell, so long as interaction information corresponding to terminal interaction can be executed, based on information interaction with the terminal, the corresponding relation between the reference signal receiving power value (or reference signal receiving quality) of the position where the terminal is located and the uplink channel quality and the downlink channel quality can be estimated, then the channel quality statistical table of the cell is updated correspondingly, and values of the uplink channel quality parameters and the downlink channel quality parameters corresponding to other reference signal receiving power intervals in the channel quality statistical table of the cell are corrected according to the uplink channel quality and the downlink channel quality corresponding to the reference signal receiving power of the terminal, so that the values of the corresponding channel quality parameters in the channel quality statistical table of the cell in the cell tend to the actual performance of the cell channel.

Therefore, in some examples of this embodiment, the more general principle for 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 receiving parameters, obtaining corresponding channel quality parameter values according to corresponding interaction information obtained from the terminal, and taking the obtained channel quality parameter values as the standard; and if the corresponding channel quality parameter value is not obtained according to the corresponding interactive information obtained from the terminal, correcting the channel quality parameter according to the channel quality parameter adjustment direction or the adjustment value obtained by estimating according to the channel quality parameter value obtained by the interactive information.

In addition, it should be understood that the variation of the channel quality of a cell may be periodic, for example, for some cells, the variation of the channel quality may conform to a variation period of one worship (some cells may be one day or one month, etc.); at this time, when the channel quality statistics is performed for the cell, periodic statistics can be performed, and after the periodic statistics result is stable, corresponding values of corresponding parameters in the corresponding cell channel quality statistics table in the period are basically counted, and the value change fluctuation of corresponding time in different periods is small. Therefore, optionally, in this embodiment, the communication device may determine that the statistical table of the channel quality of the cell counted by the communication device is stable, and then store the table into the background cell quality summarizing database.

In addition, in some examples of this embodiment, for a certain cell, the channel quality of the cell corresponding to different periods of time in a cycle may be relatively stable. For example, in a certain day of a certain month of a certain year, a parameter value corresponding to the cell channel quality of a certain cell from 00:00 to 6:00 is in a stable state, and a parameter value corresponding to the cell channel quality of from 6:00 to 18:00 is in another stable state; at a ratio of 18:00 to 00: the parameter value corresponding to the cell channel quality of 00 is another stable state; for this situation, optionally, in some examples of this embodiment, a cell channel quality statistics table of one cell may be set to include multiple time periods, where each time period corresponds to an uplink channel quality parameter and a downlink channel quality parameter corresponding to reference signal receiving parameters with different interval values;

in this example, after the interactive information is acquired, acquiring the current time is further included; according to the acquired cell quality parameter values, updating the corresponding cell quality parameters in the cell channel quality statistical table of the cell comprises the following steps:

and determining the current time to determine the corresponding target time interval in the cell channel quality statistical table, and updating the cell quality parameters corresponding to the target time interval according to the obtained cell quality parameter values.

For example, please refer to fig. 6, in an example, two time periods (the number of the time periods and the value of each time period can be flexibly set according to specific requirements) respectively correspond to a set of reference signal receiving parameters, uplink channel quality parameters, and downlink uplink channel quality parameters; wherein the reference signal receiving parameter includes a reference signal receiving power, the uplink channel quality parameter includes a single resource block signal-to-interference ratio and an uplink block error rate (of course, only any one of the single resource block signal-to-interference ratio and the uplink block error rate may be included), and the downlink channel quality parameter may include, but is not limited to, a modulation and coding strategy and a downlink block error rate (of course, only any one of the modulation and coding strategy and the downlink block error rate may be included). Referring to fig. 6, in this example, the length of the interval for which the reference signal received power is set to be 15db, but may be any value between 1db and 15 db. The specific value of the interval length can be flexibly set according to specific requirements. In this example, the reference signal receiving power value, the single resource block signal-to-interference ratio value, the uplink block error rate value, the modulation and coding strategy, the downlink block error rate, and the current time may be obtained based on the interaction information with the terminal; and determining which time interval the obtained current time belongs to (for example, assuming as a first time interval), and which reference signal received power interval the obtained reference signal received power value belongs to in the time interval (for example, assuming as an interval of-64 dBm to-49 dBm), then updating the single resource block signal-to-dry ratio, the uplink block error rate value, the modulation and coding strategy value, and the downlink block error rate corresponding to the reference signal received power interval of-64 dBm to-49 dBm in fig. 6 according to the obtained single resource block signal-to-dry ratio, the uplink block error rate value, the modulation and coding strategy value, and the downlink block error rate.

In this embodiment, the cell channel quality statistics table of the cell is stored in a background management device (e.g., a background gateway device), and may be directly loaded from the background management device when the cell is restarted (optionally, the cell channel quality statistics table of the cell may be loaded, and optionally, the cell channel quality statistics table of at least one neighboring cell of the cell may also be loaded), which may reduce the statistics time (i.e., learning time) and improve the acquisition efficiency.

In some examples of this embodiment, it may also be required that, initially, the cell starts to store the channel quality statistics table of the cell to the background according to a preset time interval (e.g. 20 minutes), and then updates the channel quality statistics table of the cell at a certain time interval, according to the requirement, and this action is stored until the channel quality is stable. After the cell is restarted, the loading can be directly carried out from the background. And the cell can be continuously detected to update the cell channel quality statistical table until the channel is stable. And after the channel is detected to be stable, the channel can not be monitored any more or the detection frequency can be reduced according to the requirement, and the channel can also be continuously monitored according to the original detection strategy.

Thus, each cell can perform statistics (or learning) storage on the cell channel quality of each cell based on the cell channel quality acquisition method of the above example, and store the cell channel quality for calling.

For example, in some application scenarios of this embodiment, for a certain cell, the unique identification information of the neighboring cell of the cell may be obtained in addition to the statistics of the cell channel quality of the cell in the above exemplary manner; and calling a cell channel quality statistical table of the adjacent cell from a cell quality summarizing database according to the acquired unique identification information of the adjacent cell. For example, in an application scenario, after the cell operates, according to the configured information of the neighboring cell, a cell channel quality statistical table of the neighboring cell to the neighboring cell is sent to the neighboring cell, if the cell is an initial operating cell, the cell is recommended to be normal and then delayed for 10-20 minutes, and then the cell channel quality statistical table is obtained from the neighboring cell or a cell channel quality statistical table of the neighboring cell is inquired from a background. In some examples of this embodiment, if the current cell fails to acquire its neighbor cell summary table, the acquisition procedure may be initiated again (1 ≦ n ≦ 4) at a random interval of n × 20 (or set to another value) minutes.

In some application scenarios of this embodiment, the cell channel quality obtaining method further includes at least one of the following:

when receiving the neighbor cell channel quality change notification message, the local cell may re-acquire the cell channel quality statistics table of the target neighbor cell corresponding to the neighbor cell channel quality change notification message, in one example, the changed parameter of the target neighbor cell may be directly acquired, and the changed parameter in the cell channel quality statistics table corresponding to the target neighbor cell that has been acquired may be updated correspondingly.

Correspondingly, in an application scenario of this embodiment, after updating the corresponding cell quality parameter in the cell channel quality statistics table of the current cell, a neighbor cell channel quality change notification message may also be sent to each serving cell that uses the cell as a neighbor cell.

Optionally, in this embodiment, before the cell channel quality statistics table of the neighboring cell is retrieved from the cell quality summary database according to the unique identification information of the neighboring cell, in order to avoid a conflict between a cell quality statistics or query process and service execution in the cell and other related operations, at least one of the following may be further included:

determining the calling time of the cell channel quality statistical table, and calling the cell channel quality statistical table of the neighbor cell from the cell quality summary database according to the unique identification information of the neighbor cell when the calling time of the cell channel quality statistical table is reached; the manner of determining the call time of the cell channel quality statistics table may be determined based on at least one of a traffic condition, a traffic variation trend, a channel quality variation trend, and the like of the cell, in one example, the call time of the cell channel quality statistics table may be determined by using a relatively predicted collision time point advance principle (that is, a relatively predicted collision time point lag principle).

According to the acquired cell quality parameter value, before updating the corresponding cell quality parameter in the cell channel quality statistical table of the cell, the method further comprises the following steps: and determining the updating time of the cell channel quality statistical table, and updating the corresponding cell quality parameters in the cell channel quality statistical table of the cell according to the acquired cell quality parameter values when the updating time of the cell channel quality statistical table is up. The manner of determining the update time of the channel quality statistical table of the cell may also be determined based on at least one of the traffic situation, the traffic variation trend, the channel quality variation trend, and the like of the cell. The update time of the cell channel quality statistics may also use a relatively predicted collision time point advance rule (i.e., an example) or a relatively predicted collision time point lag rule.

In addition, it should be understood that, when the cell scheduling uses the cell channel quality statistical table of the neighboring cell, if there is a time interval in the cell channel quality statistical table, it needs to pay attention to call the channel quality parameter of the corresponding time interval; when the cell scheduling uses the cell channel quality statistical table of the adjacent cell, the corresponding relation of the reference signal receiving power is noticed, the reference signal receiving power is equal to that of the cell or the uplink and downlink channel quality corresponding to the reference signal receiving power index of the adjacent cell is needed according to the adjacent cell reference signal receiving power condition reported by the terminal, and then the uplink and downlink channel quality is compared with the current service channel quality of the cell.

In this embodiment, when there is an application scenario in which there are a large number of neighboring cells in a cell, and when the cell scheduling uses the neighbor cell channel quality statistics table, if the cell handover is being decided, that is, the neighbor cell channel condition is determined in advance, and the time is not allowed to be reacquired, even if the neighbor cell notifies a message that the channel quality has changed, the cell may hold the message and continue to perform the current scheduling, and after the current scheduling is finished, the neighbor cell channel quality statistics table is updated again, so that basic reservation is made for the next quality handover. And as the network characteristics tend to be stable and the channel quality changes tend to be stable over time, the temporary change events are less and less.

After the cell is restarted, the cell can directly load the channel quality information of the adjacent cell suitable for the cell on the same day. The channel quality conditions of the neighbor cells belonging to the current day are loaded from the background every day according to the needs of the current cell, and certainly, the channel quality conditions can be loaded with hour granularity or with smaller granularity, and the specific implementation strategy can be determined jointly according to multiple conditions such as network pressure, server pressure, base station pressure, network pressure and the like, so that the optimal implementation strategy is selected.

For the case of failure of requesting the neighbor cell channel quality statistics table, the communication device may preferentially switch to the cell with channel quality, and if all the neighbor cell channel quality statistics tables are not obtained, the communication device may initiate blind inter-frequency quality switching, that is, blind switching of the UE to the inter-frequency cell.

In addition, in this embodiment, in consideration of various situations such as cell creation, cell restart, and the like, the cell channel quality statistics tables of all cells are stored in the background, and a communication device (e.g., a base station) can directly obtain the channel quality statistics tables from the background after operating, which not only ensures that the channel quality information of the neighboring cells is obtained, but also ensures that the channel summary table information is not lost after the base station is powered down. This eliminates the need to start a new learning process from 0 all after the power down, thereby further improving the real-time performance.

Meanwhile, in this embodiment, the communication device learns for a period of time, the channel quality condition of the cell in the network is basically stabilized, and the probability that the communication device needs to learn becomes lower and lower as time goes on, so that after the cell operates, the cell channel quality statistical table information of the cell and the neighbor cell can be loaded to the communication device (for example, a base station) together, and no time delay is realized when the channel quality information can be used as long as the cell operates. That is, once the cell channel quality statistical table meeting the requirements of a certain time period is loaded, the base station scheduling can be directly used without learning, so that the requirement of the service on the channel quality real-time property can be met.

Once the cell channel quality acquisition device finds that the cell channel quality statistical table of a certain cell needs to be updated, the update processing module 703 performs corresponding update, and stores the updated cell channel quality statistical table to the background. The cell channel quality obtaining apparatus may also perform corresponding loading and calling on the cell channel quality statistics tables of the serving cell and the neighboring cell of the serving cell from a background, and for a specific loading and calling process, please refer to the foregoing embodiments, which is not described herein again. The cell channel quality statistical tables of the serving cell and the adjacent cells maintained and called by the cell channel quality acquisition device comprise cell uplink channel quality parameter values, so that when cell switching or redirection and the like need to take the cell channel quality as a basis, the cell uplink channel quality can be selectively used as the basis according to needs, the basis selection surface of operations such as cell switching or redirection and the like is larger and more flexible, the operation result is more accurate, the wireless network switching success rate and the wireless network service sensing capability are improved, the utilization efficiency of a wireless network can be improved, and the user experience satisfaction is improved.

S802: collecting channel quality information of the cell: once a cell is established, the cell starts to collect channel quality information of the cell, and the channel quality information can be acquired through interaction information between a terminal and a base station.

S803: determining whether the cell channel quality statistical table needs to be updated, and if so, turning to S804; otherwise, go to S802.

S804: and updating the cell channel quality statistical table.

For example, the base station acquires a reference signal received power value (RSRP/RSRQ) of a location where the terminal is located according to information interaction between the terminal and the base station, the base station modifies a comparison relation table of time, RSRP and channel quality in a local channel quality summary table according to grasped uplink and downlink channel quality information (channel quality information stable in scheduling at this time), completes a mapping task of a corresponding relation, completes revision of a cell channel quality statistics table at this time, and if the cell channel quality statistics table is shared by a cell quality summary database, the base station determines whether the cell quality summary database is needed, and if so, completes synchronization of the cell quality summary database. The base station cell is often subjected to long-time learning and revising, so that the cell channel quality statistical table tends to the actual performance of the cell channel.
