Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The inventors have found that there are sometimes a lot of user equipments accessing a cell.

Secondly, it has been found that in one case the transmission rate of the 5G cell is higher than that of the 4G cell, so that most user equipments can access the 5G cell preferentially to enjoy the higher transmission rate. However, under the condition that the 5G cell is fully loaded, the subsequent other user equipment cannot access the 5G cell to enjoy a higher transmission rate, and the other user equipment can only access the 4G cell, so that when the service data of the other user equipment needs to be transmitted at a high rate, the high transmission rate of the 5G cell cannot be shared, and only the low transmission rate of the 5G cell cannot be shared, which may cause that the service data of the other user equipment cannot be normally transmitted or cannot be transmitted on time, and the like.

In addition, it is also found that in another case, the 4G cell that the ue accesses first uses the 4G cell to transmit service data, and the 4G cell can meet the requirement when the amount of data that the ue needs to transmit is low. However, the amount of service data to be transmitted later may increase, but the user equipment may only share a low transmission rate to the 4G cell, which may cause that the service data with the increased amount of data of the user equipment cannot be normally transmitted or cannot be transmitted on time, etc.

Therefore, in order to solve the above-described problems, the present solution is proposed.

The 5G base station can acquire the network resource quantity of each user equipment accessed to the 5G cell, which occupies the 5G cell, in real time.

The network resources of the 5G cell occupied by the first user equipment may include PRBs of the 5G cell occupied by the first user equipment, and so on.

The amount of network resources occupied by the first user equipment in the 5G cell may include the number of PRBs occupied by the first user equipment in the 5G cell, etc.

The number of PRBs of the 5G cell occupied by the first user equipment may include the number of uplink PRBs of the 5G cell occupied by the first user equipment and/or the number of downlink PRBs of the 5G cell occupied by the first user equipment.

The first user equipment is one of a plurality of user equipment currently accessed to the 5G cell, or the first user equipment is more than two of the plurality of user equipment currently accessed to the 5G cell.

In addition, the first user equipment may be a user equipment supporting handover from a 5G cell to a 4G cell.

For example, if the user of the ue sets that the operation mode of the first ue includes a 5G mode and a 4G mode, it may be used as the first ue. Or if the user of the user equipment sets the working mode of the first user equipment to include the 5G mode and not include the 4G mode, the first user equipment is not used as the first user equipment.

In step S102, the 5G base station obtains a quantity ratio between the network resource quantity of the 5G cell occupied by the first user equipment and the total network resource quantity of the 5G cell.

The total amount of network resources of the 5G cell may be configured in the 5G base station in advance, and thus, the 5G base station may directly acquire the total amount of network resources of the 5G cell configured in advance.

The total amount of network resources of the 5G cell is a nominal amount, which is the maximum amount of network resources that the 5G cell can provide.

The network resources of the 5G cell may include PRBs of the 5G cell, etc.

The total amount of network resources of the 5G cell may include the total number of PRBs of the 5G cell, etc.

The total number of PRBs of the 5G cell may include the total number of uplink PRBs of the 5G cell and/or the total number of downlink PRBs of the 5G cell.

In step S103, if the number ratio is smaller than the preset threshold, the 5G base station sends a handover request to the 4G base station corresponding to the 4G cell covering the first user equipment, where the handover request carries the network resource amount of the 5G cell occupied by the first user equipment and the first number of the first user equipment, and the handover request is used to request to switch the cell accessed by the first user equipment from the 5G cell to the 4G cell, and the 4G cell covering the first user equipment is a cell not currently accessed by the first user equipment.

The first number is used to identify that the first user device has several.

In the case that the number of the first user equipment is plural, the network resource amount of the 5G cell occupied by the first user equipment may be understood as the network resource amount of the 5G cell occupied by each first user equipment.

As 5G base station, it is known in advance which of the 4G cells cover the first user equipment by communicating with the first user equipment accessing the 5G cell.

The 4G cell covering the first ue in the present application is a 4G cell supporting the ue migration. The 4G cells that do not support user equipment mobility are not under consideration in the schemes of the present application.

In this application, the quantitative ratio may be compared to a preset threshold.

Under the condition that the number ratio is greater than or equal to the preset threshold, the network resource amount occupied by the first user equipment is often more, namely, the first user equipment is high-flow user equipment, and the high-flow user equipment can be understood as user equipment which is in video chat, watching video, downloading large files, using VR or using AR, and the like, so that a cell accessed by the first user equipment can not be switched from a 5G cell to a 4G cell.

In the case that the number ratio is smaller than the preset threshold, it means that the amount of network resources occupied by the first user equipment is often smaller, that is, the first user equipment is low-traffic user equipment, and the low-traffic user equipment can be understood as user equipment browsing e-mail, browsing news or typing chat, etc., so that an attempt can be made to switch the cell accessed by the first user equipment from the 5G cell to a 4G cell.

In one embodiment, the network resources of the 5G cell comprise PRBs of the 5G cell, etc.

The preset threshold includes a preset uplink threshold and a preset downlink threshold.

As such, the preset threshold may include a PRB number threshold of the 5G cell, and the like.

The PRB number threshold of the 5G cell may include an uplink PRB number threshold of the 5G cell and/or a downlink PRB number threshold of the 5G cell.

If the number ratio between the number of uplink PRBs of the 5G cell occupied by the first user equipment and the total number of uplink PRBs of the 5G cell is greater than or equal to the uplink PRB number threshold of the 5G cell, and/or if the number ratio between the number of downlink PRBs of the 5G cell occupied by the first user equipment and the total number of downlink PRBs of the 5G cell is greater than or equal to the downlink PRB number threshold of the 5G cell, the first user equipment may be high-flow user equipment, and the 5G base station does not send a handover request to the 4G base station corresponding to the 4G cell covering the first user equipment.

Or if the number ratio between the number of uplink PRBs of the 5G cell occupied by the first user equipment and the total number of uplink PRBs of the 5G cell is smaller than the uplink PRB number threshold of the 5G cell, and the number ratio between the number of downlink PRBs of the 5G cell occupied by the first user equipment and the total number of downlink PRBs of the 5G cell is smaller than the downlink PRB number threshold of the 5G cell, the first user equipment is a low-flow user equipment, and the 5G base station sends a handover request to a 4G base station corresponding to a 4G cell covering the first user equipment.

In the present application, a unified preset threshold is required to be adopted for cooperation between the 4G cell and the 5G cell, and the present application may define a unified preset threshold. To ensure that the identification results of the high-traffic user equipment and the low-traffic user equipment identified by the 4G base station or the 5G base station are consistent.

Further, in view of the difference in resource allocation of the 4G cell or the 5G cell, for example, the total amount of network resources of the 5G cell and the total amount of network resources of the 4G cell are different, so that the uniform preset threshold is required to be converted relative to the resource allocation of the 4G cell or the 5G cell.

For example, the conversion method for converting the unified preset threshold into the preset threshold corresponding to the 4G cell includes:

preset threshold corresponding to 4G cell=unified preset threshold×273×k/total network resource of cell.

The total amount of network resources of a cell may include the total number of PRBs of the cell, etc.

The total amount of network resources (total number of PRBs) of the 5G cell may be 273. The total amount of network resources (total number of PRBs) of the 4G cell may be 100.

k is a conversion factor, and the conversion factor corresponding to the 5G cell may be 1.5,4G cell and 1.

In one example, assume that the unified upstream preset threshold comprises 4%. The preset uplink threshold corresponding to the converted 5G is 4% x 273 x 1.5/273=6%.

Alternatively, in another example, assume that the unified downlink preset threshold comprises 3%. The preset downlink threshold corresponding to the converted 5G is 3% x 273 x 1.5/273=4.5%.

In step S104, the 4G base station receives a handover request sent by the 5G base station.

In step S105, the 4G base station obtains a second number of second user equipments having access to the 4G cell and a maximum number of user equipments for which the 4G cell supports the connection.

The second number of second user equipments having access to the 4G cell may include the current RRC connected state user number of the 4G cell, i.e. the number of user equipments establishing a connection with the 4G base station corresponding to the 4G cell.

The second number of the second user equipments having access to the 4G cell may be counted by the 4G base station in real time, and the specific counting mode may refer to a currently existing mode, and the specific counting mode is not limited in the present application.

In step S106, the 4G base station obtains a number difference between the maximum number and the second number.

In step S107, in the case where the number difference is greater than or equal to the first number, the 4G base station acquires the amount of idle network resources of the 4G cell.

If the number difference is greater than or equal to the first number, it is indicated that the 4G cell can also accommodate access of the first user equipment (i.e., the 4G base station corresponding to the 4G cell can also establish a connection with the first user equipment), and it can be continuously determined whether the 4G cell can provide network resources required by the first user equipment for the first user equipment.

Or, if the number difference is smaller than the first number, it is indicated that the 4G cell cannot accommodate the access of the first user equipment (i.e., the 4G base station corresponding to the 4G cell cannot establish a connection with the first user equipment), so that the 4G base station may directly send an indication of refusing to switch to the 5G base station, so that the 5G base station receives the indication of refusing to switch, and determines that the 4G base station is not used as a switching destination of the first user equipment according to the indication of refusing to switch, and then the 5G base station continues to search for other 4G cells.

In step S108, when the amount of idle network resources of the 4G cell is greater than or equal to the amount of network resources of the 5G cell occupied by the first ue, the 4G base station sends a handover response to the 5G base station, where the handover response is used to indicate that the cell to which the first ue accesses is agreed to be handed over from the 5G cell to the 4G cell.

When the amount of idle network resources of the 4G cell is greater than or equal to the amount of network resources of the 5G cell occupied by the first user equipment, it is indicated that the 4G cell can also provide the first user equipment with network resources required to be used by the first user equipment, so that the 4G base station can serve as a switching destination of the first user equipment, and further the 4G base station can send a switching response to the 5G base station, where the switching response is used for indicating that the cell to which the first user equipment is allowed to access is switched from the 5G cell to the 4G cell.

Or, under the condition that the idle network resource amount of the 4G cell is smaller than the network resource amount of the first user equipment occupying the 5G cell, the 4G cell is not capable of providing the first user equipment with the network resource required to be used by the first user equipment, so that the 4G base station can directly send an indication of refusing to switch to the 5G base station, so that the 5G base station receives the indication of refusing to switch, and determines that the 4G base station is not used as a switching destination of the first user equipment according to the indication of refusing to switch, and the 5G base station continues to search for other 4G cells.

In step S109, the 5G base station receives a handover response transmitted from the 4G base station.

In step S110, the 5G base station instructs the first user equipment to switch the cell accessed by the first user equipment from the 5G cell to the 4G cell according to the switching response.

In the present application, in the case of defining one 4G cell (handover destination) to which the first user equipment may be handed over, a specific handover manner in which the first user equipment switches the cell to which the first user equipment is connected from the 5G cell to the defined one 4G cell may refer to a handover manner that already exists at present, which is not limited in the present application.

In one embodiment of the present application, the 4G cell is one, and the 5G base station receives a handover response, where the handover response is sent by the one 4G cell, so the 5G base station can easily determine that the 4G cell to which the first ue needs to be handed over is the one 4G cell. And explicitly instructs the first ue to switch the cell accessed by the first ue from the 5G cell to the one 4G cell.

Or in another embodiment of the present application, the number of 4G cells covering the first user equipment is multiple; the switching response received by the 5G base station is multiple, and the switching response is respectively sent to the 5G base station by the 4G base station corresponding to the different 4G cells; the handover response sent by the 4G base station to the 5G base station also carries the amount of idle network resources of the 4G cell configured by the 4G base station. In this way, the 5G base station may determine which 4G cell the first user equipment needs to be handed over to among the plurality of 4G cells.

For example, the 5G base station may extract the amount of idle network resources of the 4G cell in each handover response; selecting a 4G cell with the largest idle network resource amount from a plurality of 4G cells covering the first user equipment; and indicating the first user equipment to switch the cell accessed by the first user equipment from the 5G cell to the 4G cell with the largest idle network resource amount. The first user equipment is enabled to switch the cell accessed by the first user equipment from the 5G cell to the 4G cell with the largest idle network resource amount, so that load balancing of the plurality of 4G cells on the network resource amount level is achieved.

Or in another embodiment of the present application, the number of the 4G cells covering the first user equipment is multiple; the switching response received by the 5G base station is multiple, and the switching response is respectively sent to the 5G base station by the 4G base station corresponding to the different 4G cells; the handover response sent by the 4G base station to the 5G base station also carries the amount of idle network resources of the 4G cell configured by the 4G base station.

The 5G may instruct the first ue to switch the cell accessed by the first ue from the 5G cell to one 4G cell according to the response, and since the number of 4G cells is plural, the switching response is to instruct the first ue to switch the cell accessed by the first ue from the 5G cell to any one of the 4G cells, that is, it may be that the first ue determines, in the plural 4G cells, to which 4G cell the first ue needs to be switched.

For example, after receiving the handover indication, the first ue can learn to which 4G cells the first ue can be handed over according to the handover indication, for example, the handover indication carries the IDs of the 4G cells to which the first ue can be handed over, so that the first ue can measure the signal quality of each 4G cell in the 4G cells; selecting a 4G cell with highest signal quality; and switching the cell accessed by the first user equipment from the 5G cell to the 4G cell with the highest signal quality. The signal quality of the 4G cell may include RSRQ and/or RSRP of the 4G cell, etc.

Referring to fig. 3, a step flow chart of a heterogeneous system handover method of the present application is shown, where the method is applied to the heterogeneous system handover architecture shown in fig. 1, and the method is used for switching a cell accessed by a first user equipment from a 4G cell to a 5G cell, and the method includes:

in step S201, the 4G base station obtains the network resource amount of the 4G cell occupied by the first user equipment currently accessing the 4G cell.

There may be one or more user equipments currently accessing the 4G cell, and each user equipment currently accessing the 4G cell may occupy a part of the network resource amount of the 4G cell.

The 4G base station can acquire the network resource quantity of the 4G cell occupied by each user equipment accessed to the 4G cell in real time.

The network resources of the 4G cell occupied by the first user equipment may include PRBs of the 4G cell occupied by the first user equipment, and so on.

The amount of network resources occupied by the first user equipment in the 4G cell may include the number of PRBs occupied by the first user equipment in the 4G cell, etc.

The number of PRBs of the 4G cell occupied by the first user equipment may include the number of uplink PRBs of the 4G cell occupied by the first user equipment and/or the number of downlink PRBs of the 4G cell occupied by the first user equipment.

The first user equipment is one of a plurality of user equipment currently accessed to the 4G cell, or the first user equipment is more than two of the plurality of user equipment currently accessed to the 4G cell.

In addition, the first user equipment may be a user equipment supporting handover from a 4G cell to a 5G cell.

For example, if the user of the ue sets that the operation mode of the first ue includes a 4G mode and a 5G mode, it may be used as the first ue. Or if the user of the user equipment sets the working mode of the first user equipment to include the 4G mode and not include the 5G mode, the first user equipment is not used as the first user equipment.

In step S202, the 4G base station obtains a quantity ratio between the network resource quantity of the 4G cell occupied by the first user equipment and the total network resource quantity of the 4G cell.

The total amount of network resources of the 4G cell may be configured in the 4G base station in advance, and thus, the 4G base station may directly acquire the total amount of network resources of the 4G cell configured in advance.

The total amount of network resources of the 4G cell is a nominal amount, which is the maximum amount of network resources that can be provided by the 4G cell.

The network resources of the 4G cell may include PRBs of the 4G cell, etc.

The total amount of network resources of the 4G cell may include the total number of PRBs of the 4G cell, etc.

The total number of PRBs of the 4G cell may include the total number of uplink PRBs of the 4G cell and/or the total number of downlink PRBs of the 4G cell.

In step S203, if the number ratio is greater than or equal to the preset threshold, the 4G base station sends a handover request to the 5G base station corresponding to the 5G cell covering the first user equipment, where the handover request carries the network resource amount of the 4G cell occupied by the first user equipment and the first number of the first user equipment, and the handover request is used to request to switch the cell accessed by the first user equipment from the 4G cell to the 5G cell, and the 5G cell covering the first user equipment is a cell not currently accessed by the first user equipment.

The first number is used to identify that the first user device has several.

In the case that the number of the first user equipment is plural, the network resource amount of the 4G cell occupied by the first user equipment may be understood as the network resource amount of the 4G cell occupied by each first user equipment.

As a 4G base station, it is known in advance which of the 5G cells cover the first user equipment by communicating with the first user equipment accessing the 4G cell.

The 5G cell covering the first ue in the present application is a 5G cell supporting the ue migration. 5G cells that do not support user equipment mobility are not under consideration in the schemes of the present application.

Under the condition that the number ratio is greater than or equal to a preset threshold, the network resource amount occupied by the first user equipment is often more, namely, the first user equipment is high-flow user equipment, and the high-flow user equipment can be understood as user equipment which is in video chat, watching video, downloading large files, using VR or using AR, and the like, so that an attempt can be made to switch a cell accessed by the first user equipment from a 4G cell to a 5G cell.

Under the condition that the quantity ratio is smaller than the preset threshold, the network resource amount occupied by the first user equipment is usually smaller, namely the first user equipment is low-flow user equipment, the low-flow user equipment can be understood as user equipment which is browsing e-mail, browsing news or typing chat, and the like, and therefore a cell accessed by the first user equipment can not be switched from a 4G cell to a 5G cell.

In one embodiment, the network resources of the 4G cell comprise PRBs of the 4G cell, etc.

As such, the preset threshold may include a PRB number threshold of the 4G cell, etc.

The PRB number threshold of the 4G cell may include an uplink PRB number threshold of the 4G cell and/or a downlink PRB number threshold of the 4G cell.

If the number ratio between the number of uplink PRBs of the 4G cell occupied by the first user equipment and the total number of uplink PRBs of the 4G cell is greater than or equal to the uplink PRB number threshold of the 4G cell, and/or if the number ratio between the number of downlink PRBs of the 4G cell occupied by the first user equipment and the total number of downlink PRBs of the 4G cell is greater than or equal to the downlink PRB number threshold of the 4G cell, the first user equipment may be high-flow user equipment, and the 4G base station sends a handover request to a 5G base station corresponding to the 5G cell covering the first user equipment.

Or if the number ratio between the number of uplink PRBs of the 4G cell occupied by the first user equipment and the total number of uplink PRBs of the 4G cell is smaller than the uplink PRB number threshold of the 4G cell, and the number ratio between the number of downlink PRBs of the 4G cell occupied by the first user equipment and the total number of downlink PRBs of the 4G cell is smaller than the downlink PRB number threshold of the 4G cell, the first user equipment is low-flow user equipment, and the 4G base station does not send a handover request to the 5G base station corresponding to the 5G cell covering the first user equipment.

In the present application, a unified preset threshold is required to be adopted for cooperation between the 5G cell and the 4G cell, and a unified preset threshold can be defined in the present application. To ensure that the identification results of the high-traffic user equipment and the low-traffic user equipment identified by the 5G base station or the 4G base station are consistent.

Further, in view of the difference in resource allocation of the 5G cell or the 4G cell, for example, the total amount of network resources of the 4G cell and the total amount of network resources of the 5G cell are different, so that the uniform preset threshold is required to be converted relative to the resource allocation of the 5G cell or the 4G cell.

For example, the conversion method for converting the unified preset threshold into the preset threshold corresponding to the 5G cell includes:

preset threshold corresponding to 5G cell=unified preset threshold×273×k/total network resource of cell.

In one example, assume that the unified upstream preset threshold comprises 4%. The preset uplink threshold corresponding to the converted 5G is 4% x 273 x 1/100=10.92%.

Alternatively, in another example, assume that the unified downlink preset threshold comprises 3%. The preset downlink threshold corresponding to the converted 5G is 3% x 273 x 1/100=8.19%.

In step S204, the 5G base station receives a handover request sent by the 4G base station.

In step S205, the 5G base station obtains a second number of second user equipments having access to the 5G cell and a maximum number of user equipments for which the 5G cell supports the connection.

The second number of second user equipments having access to the 5G cell may include the current RRC connected state user number of the 5G cell, i.e. the number of user equipments establishing a connection with the 5G base station corresponding to the 5G cell.

The second number of the second user equipments having access to the 5G cell may be counted by the 5G base station in real time, and the specific counting mode may refer to a currently existing mode, and the specific counting mode is not limited in the present application.

In step S206, the 5G base station obtains a number difference between the maximum number and the second number.

In step S207, in the case where the number difference is greater than or equal to the first number, the 5G base station acquires the amount of idle network resources of the 5G cell.

When the number difference is greater than or equal to the first number, it is indicated that the 5G cell can also accommodate access of the first user equipment (i.e., the 5G base station corresponding to the 5G cell can also establish connection with the first user equipment), and it can be continuously determined whether the 5G cell can provide network resources required by the first user equipment for the first user equipment.

Or, if the number difference is smaller than the first number, it is indicated that the 5G cell cannot accommodate the access of the first user equipment (i.e., the 5G base station corresponding to the 5G cell cannot establish a connection with the first user equipment), so that the 5G base station may directly send an indication of refusing to switch to the 4G base station, so that the 4G base station receives the indication of refusing to switch, and determines that the 5G base station is not used as a switching destination of the first user equipment according to the indication of refusing to switch, and then the 4G base station continues to search for other 5G cells.

In step S208, when the amount of idle network resources of the 5G cell is greater than or equal to the amount of network resources of the 4G cell occupied by the first ue, the 5G base station sends a handover response to the 4G base station, where the handover response is used to indicate that the cell to which the first ue accesses is agreed to be handed over from the 4G cell to the 5G cell.

When the amount of idle network resources of the 5G cell is greater than or equal to the amount of network resources of the 4G cell occupied by the first user equipment, it is indicated that the 5G cell can also provide the first user equipment with network resources required to be used by the first user equipment, so that the 5G base station can serve as a switching destination of the first user equipment, and further the 5G base station can send a switching response to the 4G base station, where the switching response is used for indicating that the cell to which the first user equipment is allowed to access is switched from the 4G cell to the 5G cell.

Or, under the condition that the idle network resource amount of the 5G cell is smaller than the network resource amount of the 4G cell occupied by the first user equipment, the 5G cell is not capable of providing the first user equipment with the network resource required to be used by the first user equipment, so that the 5G base station can directly send an indication of refusing to switch to the 4G base station, so that the 4G base station receives the indication of refusing to switch, and determines that the 5G base station is not used as a switching destination of the first user equipment according to the indication of refusing to switch, and the 4G base station continues to search for other 5G cells.

In step S209, the 4G base station receives a handover response transmitted from the 5G base station.

In step S210, the 4G base station instructs the first user equipment to switch the cell accessed by the first user equipment from the 4G cell to the 5G cell according to the switching response.

In the present application, in the case of defining one 5G cell (handover destination) to which the first user equipment may be handed over, a specific handover manner in which the first user equipment switches the cell to which the first user equipment is connected from the 4G cell to the defined one 5G cell may refer to a currently existing handover manner, which is not limited in the present application.

In one embodiment of the present application, the 5G cell is one, and the 4G base station receives a handover response, where the handover response is sent by the one 5G cell, so the 4G base station can easily determine that the 5G cell to which the first ue needs to be handed over is the one 5G cell. And explicitly instructs the first ue to switch the cell accessed by the first ue from the 4G cell to the one 5G cell.

Or in another embodiment of the present application, the 5G cells covering the first user equipment are multiple; the switching response received by the 4G base station is multiple, and the switching responses are respectively sent to the 4G base station by the 5G base stations corresponding to different 5G cells; the handover response sent by the 5G base station to the 4G base station also carries the amount of idle network resources of the 5G cell configured by the 5G base station. In this way, the 4G base station may determine which 5G cell the first user equipment needs to be handed over to among the plurality of 5G cells.

For example, the 4G base station may extract the amount of idle network resources of the 5G cell in each handover response; selecting a 5G cell with the largest idle network resource amount from a plurality of 5G cells covering the first user equipment; and indicating the first user equipment to switch the cell accessed by the first user equipment from the 4G cell to the 5G cell with the largest idle network resource amount. The first user equipment is enabled to switch the cell accessed by the first user equipment from the 4G cell to the 5G cell with the largest idle network resource amount, so that load balancing of the plurality of 5G cells on the network resource amount level is achieved.

Or in another embodiment of the present application, the 5G cells covering the first user equipment are multiple; the switching response received by the 4G base station is multiple, and the switching responses are respectively sent to the 4G base station by the 5G base stations corresponding to different 5G cells; the handover response sent by the 5G base station to the 4G base station also carries the amount of idle network resources of the 5G cell configured by the 5G base station.

The 4G may instruct the first ue to switch the cell accessed by the first ue from the 4G cell to one 5G cell according to the response, and since the number of 5G cells is plural, the switching response indicates that the first ue may switch the cell accessed by the first ue from the 4G cell to any 5G cell, that is, it may be that the first ue determines, in the plural 5G cells, to which 5G cell the first ue needs to be switched.

For example, after receiving the handover indication, the first ue can learn to which 5G cells the first ue can be handed over according to the handover indication, for example, the handover indication carries the IDs of the 5G cells to which the first ue can be handed over, so that the first ue can measure the signal quality of each of the 5G cells; selecting a 5G cell with highest signal quality; and switching the cell accessed by the first user equipment from the 4G cell to the 5G cell with the highest signal quality. The signal quality of the 5G cell may include RSRQ and/or RSRP of the 5G cell, etc.

According to the method and the device, for the user equipment accessing the 4G cell, under the condition that the network resource of the 4G cell occupied by the user equipment is high, the situation that the current requirement of the user equipment on the network resource is high is often indicated, and under the condition that the 4G cell configured by the 4G base station cannot meet the current or later requirement of the user equipment on the network resource, so that the cell accessed by the user equipment can be switched from the 4G cell to the 5G cell in order not to influence the transmission of the service data of the user equipment, the user equipment can enjoy the high transmission rate of the 5G cell to transmit the service data of the user equipment, and the service data of the user equipment can be transmitted normally or can be transmitted on time as much as possible.

It should be noted that, for the sake of simplicity of description, the method embodiments are all described as a series of combinations of actions, but it should be understood by those skilled in the art that the present application is not limited by the order of actions described, as some steps may take place in other order or simultaneously in accordance with the present application. Further, those skilled in the art will appreciate that the embodiments described in the specification are all alternative embodiments, and that the acts referred to are not necessarily required for the present application.
