Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.
In order to solve the problem of mutual interference when a 4G base station and a 5G base station share the same frequency band, an embodiment of the present invention provides a frequency spectrum sharing method, where a frequency band from 2515Mhz to 2635Mhz is divided into 4 frequency bands, and the 4 frequency bands include a D0 frequency band, a D1 frequency band, a D2 frequency band, and a D3 frequency band. As shown in fig. 1, fig. 1 is a schematic diagram of a spectrum division according to an embodiment of the present invention. The frequency band of D0 is 2515Mhz-2575Mhz, the frequency band of D1 is 2575-2595MHz, the frequency band of D2 is 2594.8-2614.8MHz, and the frequency band of D3 is 2614.6-2634.6 MHz. The D0 band is an area shown in a blank rectangle square as shown in fig. 1, and the D1 band is an area shown by oblique lines as shown in fig. 1; the D2 frequency band is the area indicated by the vertical line shown in fig. 1; the D3 frequency band is a region formed by diagonal interleaving as shown in fig. 1. The frequency band D0 is a 5G dedicated frequency band, the frequency bands D1 and D2 are 4GH and 5G shared frequency bands, and the frequency band D3 is a 4G frequency band. The spectrum sharing method provided by the embodiment of the invention is described below with reference to fig. 1 and fig. 2. Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a spectrum sharing method according to an embodiment of the present invention, where the spectrum sharing method is implemented in a first base station, and the first base station is a 5G base station. The method comprises the following steps:
step 201, acquiring the load information of the cell of the second base station, which is sent by the second base station, under the condition that the spectrum sharing switch is turned on.
The load information comprises PRB utilization rate of a cell and type identification of the cell; the cells of the second base station include a first cell occupying a first preset frequency band, a second cell occupying a second preset frequency band, and a third cell occupying a third preset frequency band. The first predetermined frequency band is a D1 frequency band shown in fig. 1, the second predetermined frequency band is a D2 frequency band shown in fig. 1, and the third predetermined frequency band is a D3 frequency band shown in fig. 1.
The cell type identifier is used to identify a frequency point of the cell as one of a frequency point in a D1 frequency band, a frequency point in a D2 frequency band, and a frequency point in a D3 frequency band, for example, a frequency point of a cell 1 of the second base station is identified by 0 as a frequency point in a D1 frequency band, a frequency point of a cell 2 of the second base station is identified by 1 as a frequency point in a D2 frequency band, and a frequency point of a cell 3 of the second base station is identified by 2 as a frequency point in a D3 frequency band. For example, the first base station may determine, according to the received load information of each of cell 1, cell 2, and cell 3 sent by the second base station, a cell of which the type of cell 1 is D1 frequency point from a cell type identifier included in the received load information of cell 1; determining the cell 2 with the type of the frequency point D2 from the cell type identifier included in the received load information of the cell 2; and determining the cell 3 type as a cell with a frequency point D3 from the cell type identifier included in the received load information of the cell 3. Therefore, the first base station determines the PRB utilization rate of the second cell of the second base station and determines the PRB utilization rate of the third cell of the second base station according to the received load information of the cell sent by the second base station, and then determines whether a condition for releasing a preset frequency band (for example, the preset frequency band is a second preset frequency band) occupied by the cell of the first base station is satisfied according to the load information (for example, the load information of the third cell) of the cell of the second base station in step 202. It should be noted that the PRB utilization of a cell includes uplink PRB utilization and downlink PRB utilization of the cell.
Step 202, if the timing time of the first timer is greater than or equal to the first preset time, determining whether a condition of releasing a preset frequency band occupied by the cell of the first base station is met according to the load information of the cell of the second base station.
The preset frequency bands occupied by the cell of the first base station may include a D0 frequency band, a D1 frequency band, and a D2 frequency band as shown in fig. 1. Whether the condition of releasing the preset frequency band occupied by the cell of the first base station is met or not is judged, whether the condition of releasing the second preset frequency band occupied by the cell of the first base station is met or not is judged, and whether the condition of releasing the first preset frequency band occupied by the cell of the first base station is met or not is judged.
The condition for releasing the second preset frequency band occupied by the cell of the first base station comprises the following conditions:
condition 1: if the cell of the first base station occupies a first preset frequency band and a second preset frequency band, and the uplink Physical Resource Block (PRB) utilization rate of the cell of the first base station and the downlink PRB utilization rate of the cell of the first base station are both smaller than or equal to a first preset threshold value;
condition 2: and the uplink PRB utilization rate of the third cell and/or the downlink PRB utilization rate of the third cell are/is greater than or equal to a second preset threshold value.
And if the two conditions are met, the condition of releasing the second preset frequency band occupied by the cell of the first base station is met. The uplink PRB utilization rate of the cell of the first base station and the downlink PRB utilization rate of the cell of the first base station are both less than or equal to a first preset threshold, which means that the current load of the cell of the first base station is low, and more resources are unoccupied in an idle state. However, the uplink PRB utilization rate of the third cell of the second base station and/or the downlink PRB utilization rate of the third cell of the second base station is greater than or equal to the second preset threshold, which means that the current load of the third cell of the second base station is higher, and there may be a situation where resources are not enough. Under the condition, the first base station releases the second preset frequency band occupied by the cell of the first base station, and the second base station schedules the second preset frequency band, so that the resource shortage condition of the second base station is relieved.
And the coverage range of the third cell of the second base station is the same as the coverage range of the cell of the first base station.
The first preset threshold is a preset frequency spectrum sharing low-load threshold, and the second preset threshold is a preset frequency spectrum sharing high-load threshold. The first base station may obtain load information of a third cell of the second base station, which is sent by the second base station, and obtain an uplink PRB utilization rate of the third cell of the second base station or a downlink PRB utilization rate of the third cell of the second base station from the received load information of the third cell of the second base station.
It should be noted that, in order to ensure that the 5G base station uses the spectrum continuously, the 5G base station adopts a policy of preferentially releasing the second preset frequency band. In addition, since D0, D1, and D2 all belong to the same frequency band occupied by the first cell, the first base station does not need to schedule the second preset frequency band after releasing the second preset frequency band.
The condition of judging whether the first preset frequency band occupied by the cell of the first base station is released is as follows:
condition 1: if the cell of the first base station occupies a first preset frequency band, the uplink PRB utilization rate of the cell of the first base station and the downlink PRB utilization rate of the cell of the first base station are both smaller than or equal to a first preset threshold value;
condition 2: the uplink PRB utilization rate of a second cell of the second base station and/or the downlink PRB utilization rate of the second cell of the second base station is greater than or equal to a second preset threshold;
condition 3: and if the uplink PRB utilization rate of the third cell of the second base station and/or the downlink PRB utilization rate of the third cell of the second base station is greater than or equal to a second preset threshold, the condition of releasing the first preset frequency band occupied by the cell of the first base station is met.
And if the three conditions are met, the condition of releasing the first preset frequency band occupied by the cell of the first base station is met.
Step 203, if the condition of releasing the preset frequency band occupied by the cell of the first base station is satisfied, releasing the preset frequency band occupied by the cell of the first base station so that the second base station can schedule the preset frequency band.
If the condition for releasing the second preset frequency band occupied by the cell of the first base station is satisfied in step 102, the second preset frequency band occupied by the cell of the first base station is released in this step, so that the second base station can schedule the second preset frequency band. If the condition of releasing the first preset frequency band occupied by the cell of the first base station is satisfied in step 102, the first preset frequency band occupied by the cell of the first base station is released in this step, so that the second base station can schedule the first preset frequency band.
In the spectrum sharing method provided in this embodiment, the load information of the cell of the second base station, which is sent by the second base station, is acquired when the spectrum sharing switch is turned on, if the timing time of the first timer is greater than or equal to the first preset time, it is determined whether a condition for releasing the preset frequency band occupied by the cell of the first base station is satisfied according to the load information of the cell of the second base station, and if the condition for releasing the preset frequency band occupied by the cell of the first base station is satisfied, the preset frequency band occupied by the cell of the first base station is released, so that the second base station schedules the preset frequency band. The problem of mutual interference caused by the fact that the first base station and the second base station share the same frequency band is solved, the first base station releases part of the frequency band occupied by the first cell of the first base station under the condition that the preset frequency band is released, the released part of the frequency band can be used for the second base station to schedule, and friendly frequency spectrum sharing is achieved between the first base station and the second base station.
It should be noted that, when the spectrum sharing switch is turned on, the first base station may receive the load information of the cell of the second base station sent by the second base station, and store the load information of the cell of the second base station, so that the first base station determines whether the condition for releasing the preset frequency band is satisfied according to the stored load information of the cell of the second base station.
Referring to fig. 3, fig. 3 is a signaling flowchart of a spectrum sharing method according to an embodiment of the present invention, where the spectrum sharing method according to the embodiment includes the following steps:
step 301, under the condition that the cell of the first base station is in the activated state, if the timing time of the second timer is greater than or equal to a second preset time, the first base station sends the load information of the cell of the first base station to the second base station.
Under the condition that the first cell of the first base station is in the activated state, the first base station needs to determine whether the timing time of the second timer is greater than or equal to a second preset time. It should be noted that before the first base station determines whether the timing time of the second timer is greater than or equal to a second preset time, the first base station needs to determine whether the spectrum sharing switch is turned on, and if not, the spectrum sharing switch needs to be turned on, and the second timer is started to start timing; if the spectrum sharing switch is opened, the second timer can be directly started to start timing. The second timer is a periodic timer for determining whether to transmit the load information of the cell of the first base station to the second base station. If the timing time of the second timer is greater than or equal to the second preset time, sending the load information of the cell of the first base station to the second base station, after sending the load information of the cell of the first base station to the second base station, clearing the timing time of the second timer, and restarting timing to periodically judge whether the condition of sending the load information of the cell of the first base station to the second base station is met. Wherein, the second base station may be a 4G base station. It should be noted that, because the first cell of the 5G base station is a cell occupying 100M of frequency bands of D0, D1, and D2 shown in fig. 1, the load information of the cell of the first base station, which is sent by the 5G base station to the 4G base station, includes the Physical Resource Block (PRB) utilization rate of the cell of the first base station and the identification information of the cell of the first base station, and the 4G base station may determine, according to the identification information of the cell of the first base station, that the load information received by the 4G base station is the load information of the cell of the first base station.
Step 302, the second base station receives the load information of the cell of the first base station, which is sent by the first base station, under the condition that the spectrum sharing switch is turned on; the load information of the cell of the first base station comprises the Physical Resource Block (PRB) utilization rate of the cell of the first base station and the identification information of the cell of the first base station.
Step 303, if the timing time of the first timer is greater than or equal to the first preset time, the second base station determines whether a condition for releasing a preset frequency band occupied by the cell of the second base station is met according to the load information of the cell of the first base station.
The second base station determines whether the condition for releasing the preset frequency band occupied by the cell of the second base station is met or not according to the load information of the cell of the first base station, and may determine whether the condition for releasing the first preset frequency band occupied by the first cell of the second base station is met or not or determine whether the condition for releasing the second preset frequency band occupied by the second cell is met or not.
The condition that the first preset frequency band occupied by the first cell is released includes the following 4 conditions:
condition 1: under the condition that a first cell, a second cell and a third cell are in an activated state, if the coverage area of the second cell and the coverage area of the third cell contain the coverage area of the first cell;
condition 2: the PRB utilization rate of the first cell is less than or equal to a first preset threshold value;
condition 3: the PRB utilization rate of the second cell and/or the PRB utilization rate of the third cell are/is less than or equal to a first preset threshold value;
condition 4: the load of a first adjacent cell of the first cell is greater than or equal to a second preset threshold.
If all the above 4 conditions are satisfied, the condition for releasing the first preset frequency band is satisfied.
The first neighboring cell of the first cell is at least one of the cells of the first base station (for example, the first neighboring cells of the first cell are cell 1 and cell 2 of the first base station), and the coverage area of the first neighboring cell of the first cell is the same as the coverage area of the first cell. The PRB utilization of the first cell comprises an uplink PRB utilization of the first cell and a downlink PRB utilization of the first cell. The PRB utilization of the second cell comprises an uplink PRB utilization of the second cell and a downlink PRB utilization of the second cell. The PRB utilization of the third cell comprises an uplink PRB utilization of the third cell and a downlink PRB utilization of the third cell.
The condition for releasing the second preset frequency band includes the following 5 conditions:
condition 1: the first cell is not in an activated state, and the second cell and the third cell are in an activated state;
condition 2: the coverage area of the third cell comprises the coverage area of the second cell;
condition 3: the PRB utilization rate of the second cell and the PRB utilization rate of the third cell are both smaller than or equal to a first preset threshold value;
condition 4: the load of a first adjacent cell of the second cell is greater than or equal to a second preset threshold;
and if the 4 conditions are met, releasing a second preset frequency band occupied by the second cell so that the first base station can schedule the second preset frequency band. The first neighboring cell of the second cell is at least one of the cells of the first base station (for example, the first neighboring cell of the second cell is cell 1 of the first base station), and the coverage area of the first neighboring cell of the second cell is the same as the coverage area of the second cell.
And step 304, if the condition of releasing the preset frequency band occupied by the cell of the second base station is met, releasing the preset frequency band for the first base station to schedule the preset frequency band.
When the predetermined frequency channel of release is first predetermined frequency channel, before the frequency channel is predetermine in the release, still include:
and switching part of the mobile terminals accessed to the first cell to a second adjacent cell of the first cell, wherein the load of the second adjacent cell of the first cell is smaller than that of the first cell, and the coverage range of the second adjacent cell of the first cell is the same as that of the first cell.
Optionally, when the released preset frequency band is the second preset frequency band, before the release of the preset frequency band, the method further includes:
and after switching part of the mobile terminals of the second cell to a second adjacent cell of the second cell, sending a second notification message to the first base station, wherein the second notification message is used for notifying the first base station to use a second preset frequency band.
It should be noted that, if the frequency band released in step 304 is the first preset frequency band, step 305 is executed after step 304 is executed; if the second preset frequency band is released in step 304, step 306 is executed after step 304 is executed.
Step 305, after switching part of the mobile terminals of the first cell to the second neighboring cell of the first cell, the second base station sends a first notification message to the first base station, where the first notification message is used to notify the first base station to schedule the first preset frequency band.
Step 306, after switching part of the mobile terminals of the second cell to the second neighboring cell of the second cell, the second base station sends a second notification message to the first base station, where the second notification message is used to notify the first base station to use the second preset frequency band.
It should be noted that if step 305 is executed, step 307 is executed accordingly. If step 306 is performed, then step 308 is performed accordingly.
Step 307, the first base station receives the first notification message sent by the second base station, and schedules the first preset frequency band in response to the first notification message.
For example, the first base station may allocate partial PRB resources of the first preset frequency band to cell 1 and cell 2 of the first base station. Therefore, the mobile terminal accessing the cell 1 or the cell 2 can obtain more resources, and the resource shortage condition of the cell 1 and the cell 2 is relieved.
And step 308, the first base station receives a second notification message sent by the second base station, and schedules the second preset frequency band in response to the second notification message.
For example, the first base station may allocate partial PRB resources of the second preset frequency band to cell 1 and cell 2 of the first base station. Therefore, the mobile terminal accessing the cell 1 or the cell 2 can obtain more resources, and the resource shortage condition of the cell 1 and the cell 2 is relieved.
Referring to fig. 4, fig. 4 is a signaling flowchart of another spectrum sharing method according to an embodiment of the present invention, where the spectrum sharing method according to the embodiment includes the following steps:
step 401, under the condition that the cell of the second base station is in the activated state, if the timing time of the second timer is greater than or equal to a second preset time, the second base station sends the load information of the cell of the second base station to the first base station.
The cells of the second base station include a first cell occupying a first predetermined frequency band (the first predetermined frequency band is a D1 frequency band shown in fig. 1), a second cell occupying a second predetermined frequency band (the second predetermined frequency band is a D2 frequency band shown in fig. 1), and a third cell occupying a third predetermined frequency band (the third predetermined frequency band is a D3 frequency band shown in fig. 1). And under the condition that the cell of the second base station is in the activated state, the second base station needs to judge whether the timing time of the second timer is greater than or equal to second preset time. It should be noted that before the second base station determines whether the timing time of the second timer is greater than or equal to a second preset time, the second base station needs to determine whether the spectrum sharing switch is turned on, and if not, the spectrum sharing switch needs to be turned on, and the second timer is started to start timing; if the spectrum sharing switch is opened, the second timer can be directly started to start timing. The second timer is a periodic timer for determining whether to transmit load information of a cell of the second base station to the first base station. If the timing time of the second timer is greater than or equal to the second preset time, sending the load information of the cell of the second base station to the first base station, after sending the load information of the cell of the second base station to the first base station, clearing the timing time of the second timer, and restarting timing to periodically judge whether the condition of sending the load information of the cell of the second base station to the first base station is met. The second base station may be a 4G base station, the first base station may be a 5G base station, and the first base station may be the first base station in the embodiment shown in fig. 1.
It should be noted that the load information of the cell of the second base station, which is sent by the second base station to the first base station, includes the PRB utilization rate of the cell and the type identifier of the cell. The type identifier of the cell is used to indicate that the frequency point of the cell is one of a frequency point in a D1 frequency band, a frequency point in a D2 frequency band, and a frequency point in a D3 frequency band, which may specifically refer to the description in the embodiment corresponding to fig. 1, and is not described here again to avoid repetition.
And step 402, the first base station receives the load information of the cell of the second base station, which is sent by the second base station, under the condition that the spectrum sharing switch is opened.
Step 201 may be referred to in this step, and is not described herein again.
Step 403, if the timing time of the first timer is greater than or equal to the first preset time, the first base station determines whether a condition for releasing a preset frequency band occupied by the cell of the first base station is met according to the load information of the cell of the second base station.
This step can refer to step 202, and is not described herein again.
Step 404, if a condition of releasing the preset frequency band occupied by the cell of the first base station is satisfied, releasing the preset frequency band occupied by the cell of the first base station so that the second base station can schedule the preset frequency band.
If the released default frequency band is the first default frequency band in step 404, step 405 is executed. If the released default frequency band is the second default frequency band in step 404, go to step 406.
Step 405, the first base station sends a third notification message to the second base station, where the third notification message is used to instruct the second base station to schedule the first preset frequency band.
If step 405 is performed, step 407 is performed after step 405 is performed.
And step 406, the first base station sends a fourth notification message to the second base station, where the fourth notification message is used to instruct the second base station to schedule the second preset frequency band.
If step 406 is performed, step 406 is performed and then step 408 is performed.
Step 407, the second base station receives the third notification message sent by the first base station, and schedules the first preset frequency band in response to the third notification message. The third notification message is used for instructing the second base station to schedule the first preset frequency band.
And step 408, the second base station receives the fourth notification message sent by the first base station, and schedules the second preset frequency band in response to the fourth notification message. The fourth notification message is used for instructing the second base station to schedule the second preset frequency band.
In the spectrum sharing method provided in this embodiment, when the cell of the second base station is in an active state, if the timing time of the first timer is greater than or equal to a first preset time, the second base station sends the load information of the cell of the second base station to the first base station, if a condition for releasing the preset frequency band is met, the preset frequency band is released, so that the first base station schedules the preset frequency band, and if the condition for releasing the preset frequency band is met, the preset frequency band is released, so that the first base station schedules the preset frequency band.
