The resource allocation scheme provided by the embodiment of the invention is further described in detail below.

As shown in fig. 2, the resource allocation system according to the embodiment of the present invention includes a server 20 and a base station 21;

the server 20 is configured to determine, after determining that the target terminal needs to be handed over to another cell, a candidate neighbor cell capable of receiving the target terminal from at least one neighbor cell of the target cell to which the target terminal is currently connected; the target terminal is a part or all of terminals accessed to the target cell; and sending an adjustment message for adjusting the coverage of the candidate neighbor cell to the base station corresponding to the candidate neighbor cell so that the base station adjusts the coverage of the candidate neighbor cell.

A first base station 21, configured to receive an adjustment message sent by a server and used for adjusting a coverage area of a candidate neighbor cell; after determining that the target terminal needs to be switched to other cells, the candidate neighbor cell determines a cell capable of receiving the target terminal from at least one neighbor cell of the target cell currently accessed by the target terminal; the target terminal is part or all of terminals accessed to the target cell; and adjusting the coverage range of the candidate neighbor cell according to the adjustment message.

A second base station 22, configured to receive a control message sent by the server and used for controlling the target cell; the target cell is a cell accessed by a target terminal, the target terminal is a terminal which needs to be switched to other cells, and the target terminal is a part or all of terminals accessed into the target cell; and executing corresponding control operation according to the control message, wherein the control operation is used for switching the target terminal accessed to the target cell to other cells.

The first base station is a base station corresponding to a candidate neighbor cell, and the second base station is a base station corresponding to a target cell.

The server detects the network load information of each cell under each base station, and determines whether the terminal accessed to the cell needs to be switched to other cells according to the network load information of each cell;

in the implementation, comparing the acquired network load information of each cell with a preset range, if the network load information of the target cell is higher than the upper limit value of the preset range, taking part of terminals accessed into the target cell as target terminals, and switching the target terminals to other cells; and if the network load information of the target cell is lower than the lower limit value of the preset range, taking all terminals accessed into the target cell as target terminals, and switching the target terminals to other cells.

If the network load of the target cell is higher than the upper limit value of the preset range, the number of the terminals accessed in the target cell is larger, and a part of terminals accessed in the target cell need to be switched to other cells; if the network load of the target cell is lower than the lower limit value of the preset range, the number of the terminals in the target cell is smaller, and all the terminals accessed into the target cell can be switched to other cells, so that the target cell is subjected to energy-saving treatment, and the energy-saving purpose is achieved.

In an alternative implementation manner, when determining the network load information of each cell of the base station, the server may determine the network load information according to the use condition of the physical resource blocks (Physical Resource Block, PRBs) of each cell.

In addition, the embodiment of the invention can also take the cell with the fault as the target cell, and when the target cell has the fault, all terminals in the access target cell are taken as target terminals, and all terminals in the cell with the fault need to be switched to other cells.

The condition for the trigger server to adjust the network load of the target cell in the embodiment of the invention can be a periodic detection trigger mode or an event trigger mode;

Two different triggering modes are described below:

1. periodically detecting a triggering mode;

the embodiment of the invention presets a network load detection period and a network load detection duration;

after the network load detection period arrives, the server detects the network load information of each cell of the base station within the network load detection duration.

After detecting the network load information of each cell, the server compares the network load information of each cell with a preset range; the preset range is a preset network load range, for example, the preset range can be obtained based on a simulation test, or the preset range can be an experience range value of a person skilled in the art;

if the network load information of the cell is higher than the upper limit value of the preset range, determining that the network load of the cell is higher, and switching part of terminals accessed to the cell to other cells; if the network load information of the cell is lower than the lower limit value of the preset range, determining that the network load of the cell is lower, switching all terminals accessed into the cell to other cells, and performing energy-saving processing on the cell.

For example, the preset range may be [ P1, P2], where P1 is a lower limit value of the preset range, and P2 is an upper limit value of the preset range, where P2 is greater than P1; when the server detects that the network load of the target cell of the base station is greater than P2, determining that partial terminals accessed to the target cell need to be switched to other cells; when the server detects that the network load of the target cell of the base station is smaller than P1, the target cell is determined to be required to be subjected to energy saving processing, and all terminals accessed into the target cell are switched to other cells.

2. An event trigger mode;

according to the embodiment of the invention, the server determines that the network load adjustment is required to be carried out on the cell of the base station according to the event reported by the base station;

the event reported by the base station can be a cell fault event or a high network load event; for example, the network load event may be a bursty high traffic event.

In the implementation, when the base station determines that the network load of the cell is greater than a preset value, reporting a high network load event to a server; the base station judges whether a high network load event occurs or not according to the comparison of the network load of the cell with a preset value, wherein the preset value can be obtained based on a simulation test or can be an experience value of a person skilled in the art;

for example, when the network load of the cell is greater than P3 (where P3 is assumed to be a preset value set in advance for determining whether a high network load event occurs), the high traffic event that is sudden in the cell is determined, and the base station reports the sudden high traffic event to the server.

When P1, P2, and P3 are preset, P3 may be preset to be larger than P2.

After determining that a target terminal in a target cell needs to be switched to other cells, determining candidate neighbor cells capable of receiving the target terminal from at least one neighbor cell of the target cell;

In an alternative implementation manner, a server screens neighbor cells capable of covering part or all of terminals accessed to a target cell from at least one neighbor cell according to coverage areas of all neighbor cells in the at least one neighbor cell and position information of all terminals accessed to the target cell; and the server takes the neighbor cells with the network load information of which is not more than a preset threshold value in the screened neighbor cells as candidate neighbor cells.

It should be noted that, the candidate neighbor cells determined in the embodiment of the present invention need to satisfy two conditions simultaneously: 1. the candidate neighbor cell may cover some or all terminals in the target cell; 2. the network load information of the candidate neighbor cells is not more than a preset threshold value;

the preset threshold may be obtained based on a simulation test, or may be an empirical value of a person skilled in the art. When the network load of the target cell is higher than the upper limit value of the preset range or the network load of the target cell is lower than the lower limit value of the preset range, the value of the preset threshold value is not greater than the upper limit value of the preset range; for example, a preset threshold p4=p2×k1, where P2 is an upper limit value of a preset range, k1 is a preset weight coefficient, and 0< k1<1. When the target cell is a failed cell, the value of the preset threshold value is not smaller than the upper limit value of the preset range; for example, a preset threshold p4=p2×k2, where P2 is an upper limit value of a preset range, k2 is a preset weight coefficient, and k2+_1.

When determining a candidate neighbor cell from at least one neighbor cell of a target cell, the server acquires the coverage range of each neighbor cell stored in advance and acquires the position information of each terminal stored in advance;

in the implementation, the server can receive the position information reported by each terminal through the base station and the accessed cell information, so that the server can determine the coverage area corresponding to each cell;

the coverage area corresponding to each cell can be represented by longitude and latitude data.

After determining the coverage area corresponding to each cell, the server constructs and stores the corresponding relation between the coverage area of each cell and the coverage parameters of the cell according to the historical coverage parameters of each cell;

the coverage parameters of the histories of the cells in the embodiment of the invention can be the coverage parameters of the cells obtained before the corresponding relation is constructed.

Aiming at different types of target cells, the embodiment of the invention has different processing modes on the target cells and candidate neighbor cells corresponding to the target cells;

the types of the target cell include: a high network load cell, a low network load cell, and a failure cell;

the high network load cell is a cell with the network load higher than the upper limit value of the preset range, the low network load cell is a cell with the network load lower than the lower limit value of the preset range, and the fault cell is a cell with the fault.

The following description is made for different target cell types, respectively.

1. A high network load cell;

the high network load cell is a cell with the network load higher than the upper limit value of the preset range; wherein the definition of the upper limit value of the preset range can be found in the above description.

In the embodiment of the invention, a server determines that a target cell is a high network load cell, and after determining that a candidate neighbor cell capable of receiving part of terminals in the target cell is determined in neighbor cells of the target cell, coverage areas of the candidate neighbor cell and the target cell are respectively adjusted;

in the implementation, a server sends an adjustment message for adjusting the coverage area of a candidate neighbor cell to a base station corresponding to the candidate neighbor cell;

optionally, the adjustment message sent by the server to the base station corresponding to the candidate neighbor cell includes an adjustment value of the coverage parameter of the candidate neighbor cell; and after receiving the adjustment message, the base station corresponding to the candidate neighbor cell adjusts the coverage parameters of the candidate neighbor cell according to the adjustment value of the coverage parameters of the candidate neighbor cell contained in the adjustment message.

Wherein the overlay parameters include, but are not limited to:

transmit power parameters, weight parameters, beam parameters.

Before sending an adjustment message to a base station corresponding to a candidate neighbor cell, the server determines an adjustment value of a coverage parameter of the candidate neighbor cell;

optionally, the server determines an adjustment value of the coverage parameter of the candidate neighbor cell according to the coverage parameter of the candidate neighbor cell and the number of target terminals to be switched from the target cell to the candidate neighbor cell.

In the implementation, the server can determine the number of terminals needing to be switched from the target cell to the candidate neighbor cell according to the network load information of the target cell; the embodiment of the invention can determine one or more candidate neighbor cells from neighbor cells of the target cell.

Because the embodiment of the invention needs to switch part of terminals of the target cell to the candidate neighbor cells when the target cell is a high network load cell, in order to ensure that the terminals are smoothly switched to the candidate neighbor cells and ensure the network quality after the terminals are switched to the candidate neighbor cells, the coverage area of the candidate neighbor cells needs to be increased; therefore, the coverage parameter adjustment value sent by the server to the base station corresponding to the candidate neighbor cell is used for increasing the coverage of the candidate neighbor cell.

When the coverage area of the candidate neighbor cell is increased through the adjustment value of the coverage parameter of the candidate neighbor cell, for example, the transmission power parameter of the candidate neighbor cell can be selectively increased, the beam parameter can be increased, or the horizontal angle and/or the vertical angle in the weight parameter can be adjusted; thereby increasing the coverage of the candidate neighbor cells.

In addition, because the network load of the target cell needs to be reduced, the number of terminals accessing the target cell is reduced, and the coverage of the target cell can be reduced while the coverage of the candidate neighbor cell is increased;

optionally, the server generates a control message for controlling the target cell according to the network load information of the target cell; and sending the control message to the base station corresponding to the target cell, so that the base station corresponding to the target cell executes corresponding control operation according to the control message, wherein the control operation is used for enabling the target terminal accessed to the target cell to be switched to other cells.

In the implementation, when the target cell is a high network load cell, the server sends a control message for reducing the coverage of the target cell to a base station corresponding to the target cell, so that the base station corresponding to the target cell reduces the coverage of the target cell;

before a server sends a control message for reducing the coverage of a target cell to a base station corresponding to the target cell, the server acquires the coverage parameters of the target cell; determining an adjustment value of the coverage parameter of the target cell according to the coverage parameter of the target cell and the number of target terminals needing to be switched from the target cell to other cells;

And the server sends a control message containing the adjustment value of the coverage parameter of the target cell to the base station corresponding to the target cell, so that the base station corresponding to the target cell adjusts the coverage parameter of the target cell according to the adjustment value contained in the control message, and the coverage of the target cell is reduced.

When the coverage area of the target cell is reduced through the adjustment value of the coverage parameter of the target cell, for example, the transmission power parameter of the target cell can be selected to be reduced, or the beam parameter can be reduced, or the horizontal angle and/or the vertical angle in the weight parameter can be adjusted; thereby narrowing the coverage of the target cell.

It should be noted that, in the embodiment of the present invention, the server adjusts the coverage areas of the target cell and the candidate neighbor cell, and after the coverage areas of the target cell and the candidate neighbor cell change, the terminal accessing the target cell can automatically complete the handover from the target cell to the candidate neighbor cell based on the channel quality measured to each cell in the measurement reporting process, thereby reducing the network load of the target cell.

In addition, after adjusting the coverage areas of the target cell and the candidate neighbor cells, the server detects the network load of the target cell, and if the network load of the target cell is still higher than the upper limit value of the preset range, the server reports capacity expansion alarm information to prompt that the capacity expansion processing is required to be carried out on the target cell.

The resource allocation flow chart shown in fig. 3, in which the target cell is taken as an example of a high network load cell, includes the following steps:

step S301, a server detects each cell of a base station and determines network load information of each cell;

step S302, a server determines that the network load information of a target cell is higher than the upper limit value of a preset range;

step S303, the server screens out adjacent cells which can cover part or all of the terminals accessed to the target cell from at least one adjacent cell according to the coverage area of each adjacent cell in at least one adjacent cell of the target cell and the position information of each terminal accessed to the target cell;

step S304, the server takes the neighbor cells with the network load information of which is not more than a preset threshold value in the screened neighbor cells as candidate neighbor cells;

step S305, the server determines the adjustment value of the coverage parameter of the candidate neighbor cell;

step S306, the server sends an adjustment message containing the adjustment value of the coverage parameter of the candidate neighbor cell to the base station corresponding to the candidate neighbor cell;

for convenience of description, the base station corresponding to the candidate neighbor cell is referred to as a first base station in the following flow;

step S307, the first base station adjusts the coverage parameters of the candidate neighbor cells according to the adjustment values contained in the adjustment message so as to increase the coverage of the candidate neighbor cells;

Step S308, the server determines the adjustment value of the coverage parameter of the target cell, and generates a control message for narrowing the coverage of the target cell, wherein the control message comprises the adjustment value of the coverage parameter;

step S309, the server sends a control message containing the adjustment value of the coverage parameter of the target cell to the base station corresponding to the target cell;

for convenience of description, the base station corresponding to the target cell is referred to as a second base station in the following procedure;

step S310, the second base station adjusts the coverage parameters of the target cell according to the adjustment value contained in the control message so as to reduce the coverage of the target cell;

the low network load cell is a cell with the network load lower than the lower limit value of the preset range; wherein the definition of the lower limit value of the preset range can be found in the above description.

According to the embodiment of the invention, the server determines that the target cell is a low network load cell, and the server can send the control message to the base station corresponding to the target cell, so that the base station corresponding to the target cell can perform energy-saving treatment on the target cell.

Before performing energy-saving treatment on a target cell, in order to avoid user perception, the embodiment of the invention needs to ensure that a terminal accessed into the target cell is switched to a candidate neighbor cell; an alternative implementation manner is that the server adjusts the coverage of the candidate neighbor cells;

Wherein the overlay parameters include, but are not limited to:

transmit power parameters, weight parameters, beam parameters.

In addition, as the target cell is a low network load cell, the server can select the target cell for energy saving treatment in order to save resources and reduce energy consumption;

In implementation, the server sends a control message for performing energy-saving processing on the target cell to the base station corresponding to the target cell, so that the base station corresponding to the target cell performs energy-saving processing on the target cell.

In some embodiments, if it is determined that network load information of a cell corresponding to an active antenna unit (Active Antenna Unit, AAU) is lower than the lower limit value of the preset range, the server sends an energy-saving control message to the AAU, so that the AAU enters an energy-saving state after receiving the energy-saving control message;

if the server determines that the network load information of the cell corresponding to the baseband processing unit (Building Base band Unite, BBU) is lower than the lower limit value of the preset range, the server sends an energy-saving control message to the BBU so that the BBU enters an energy-saving state after receiving the energy-saving control message;

if the server determines that the network load information of the cells corresponding to the logic stations is lower than the lower limit value of the preset range, the server sends an energy-saving control message to the logic stations, so that the logic stations enter an energy-saving state after receiving the energy-saving control message.

In addition, in order to avoid the problem of coverage area in the dynamic adjustment process of the cell coverage area, if more than one non-fault or energy-saving site exists between the terminal and the currently accessed target cell, even if the target cell can be covered by other cells, the energy-saving processing is not performed on the target cell.

It should be noted that, in the embodiment of the present invention, the server adjusts the coverage area of the candidate neighbor cell, after the energy-saving processing of the target cell, the terminal accessing the target cell can automatically complete the handover from the target cell to the candidate neighbor cell based on the measured channel quality of each cell in the measurement reporting process.

The resource allocation flow chart shown in fig. 4, in which the target cell is taken as an example of a low network load cell, includes the following steps:

step S401, a server detects each cell of a base station and determines network load information of each cell;

step S402, the server determines that the network load information of the target cell is lower than the lower limit value of the preset range;

step S403, the server screens out the adjacent cells which can cover part or all of the terminals accessed to the target cell from at least one adjacent cell according to the coverage area of each adjacent cell in at least one adjacent cell of the target cell and the position information of each terminal accessed to the target cell;

Step S404, the server takes the neighbor cells with the network load information of which is not more than a preset threshold value in the screened neighbor cells as candidate neighbor cells;

step S405, a server determines an adjustment value of a coverage parameter of a candidate neighbor cell;

step S406, the server sends an adjustment message containing the adjustment value of the coverage parameter of the candidate neighbor cell to the base station corresponding to the candidate neighbor cell;

step S407, the first base station adjusts the coverage parameters of the candidate neighbor cells according to the adjustment values contained in the adjustment message so as to increase the coverage of the candidate neighbor cells;

step S408, the server sends a control message for carrying out energy-saving processing on the target cell to a base station corresponding to the target cell;

and step S409, the second base station performs energy-saving processing on the target cell.

3. A failure cell;

in the embodiment of the invention, a server determines a target cell as a fault cell, and in neighbor cells of the target cell, after determining candidate neighbor cells capable of receiving terminals in the target cell, the coverage of the candidate neighbor cells is adjusted;

Wherein the overlay parameters include, but are not limited to:

transmit power parameters, weight parameters, beam parameters.

It should be noted that, in the embodiment of the present invention, the server adjusts the coverage area of the candidate neighbor cell, and after the target cell fails, the terminal accessing the target cell can automatically complete the handover from the target cell to the candidate neighbor cell based on the measured channel quality of each cell in the measurement reporting process.

The resource allocation flow chart shown in fig. 5, in which the target cell is taken as a failure cell, includes the following steps:

Step S501, the server detects each cell of the base station;

step S502, a server determines that a target cell fails;

step S503, the server screens out the adjacent cells which can cover part or all of the terminals accessed to the target cell from at least one adjacent cell according to the coverage area of each adjacent cell in at least one adjacent cell of the target cell and the position information of each terminal accessed to the target cell;

step S504, the server takes the neighbor cells with the network load information not more than a preset threshold value in the screened neighbor cells as candidate neighbor cells;

step S505, the server determines the adjustment value of the coverage parameter of the candidate neighbor cell;

step S506, the server sends an adjustment message containing the adjustment value of the coverage parameter of the candidate neighbor cell to the base station corresponding to the candidate neighbor cell;

step S507, the first base station adjusts the coverage parameters of the candidate neighbor cells according to the adjustment values contained in the adjustment message so as to increase the coverage of the candidate neighbor cells;

step S508, the server detects whether all terminals accessed to the target cell are switched to the candidate neighbor cell; if not, the server reports that the coverage holes exist, and if so, the server reports that the terminals of the target cell are all switched to the candidate neighbor cells.
