The present disclosure relates to the field of communication technology, and in particular to methods and apparatuses for reconfiguring a cell.
In a handover of a 4th Generation mobile communication technology (4G for short), the network can send a handover request to a handover target cell based on a measurement report result of user equipment (UE for short). When a confirmation of the handover target cell is completed, the network may send a handover command carrying configuration information of the handover target cell to the UE. After receiving the handover command, the UE may initiate a random access to the handover target cell.
In order to improve robustness of the handover, a conditional handover (CHO for short) is proposed in a fifth generation mobile communication technology (5G for short), that is, the network can configure the handover target cell and a handover trigger condition for the UE in advance. When the handover trigger condition is met, the UE can initiate the handover by itself without the need for the network to sending the handover command.
However, in the CHO, if a signal strength relationship of a neighbor cell changes, the UE may not update the measurement report result, and the network may not change the handover target cell. This may cause the UE to perform a handover to a cell with a weaker signal, which in turn leads to frequent handovers or a handover failure.
In order to overcome the problems in the related art, the embodiments of the present disclosure provide methods and apparatuses for reconfiguring a cell.

At step 110, it is determined that a handover target cell configured by a base station for the terminal is a first neighbor cell.
In the embodiments of the present disclosure, the first neighbor cell may be a handover target cell configured by the base station for the terminal in a conditional handover (CHO for short).
At step 120, a cell reconfiguration condition is determined, where the cell reconfiguration condition is a specified condition for triggering the terminal to request the base station to reconfigure the handover target cell.
In the embodiments of the present disclosure, the cell reconfiguration condition is a specified condition set for changing the handover target cell in the CHO, in order to prevent the terminal from performing a handover to a cell with a weaker signal, which in turn may lead to frequent handovers or a handover failure.
In an embodiment, the cell reconfiguration condition in the step 120 may include a first measurement report condition, where the first measurement report condition is that a neighbor cell after offset is better than the first neighbor cell; its specific implementation can be seen in the embodiment shown in
The first measurement report condition may be a measurement report condition newly defined in the present disclosure, which includes: event A7; that is, a neighbor cell after offset is better than a specific neighbor cell (or neighbor becomes offset better than neighbor X). The specific neighbor cell is the first neighbor cell in the present disclosure.
In an embodiment, the first measurement report condition may be a measurement report condition configured by the base station for the terminal and sent to the terminal through the first configuration information. The specific implementation includes:
In an embodiment, the first configuration information in the (1-1) may further include a specified offset value configured by the base station for the terminal. For example, the specified offset value is 3 db.
In an embodiment, the cell reconfiguration condition in the step 120 may be a handover failure for the first neighbor cell; its specific implementation can be seen in the embodiment shown in
At step 130, when it is detected that the cell reconfiguration condition is met, a specified measurement result for reconfiguring the handover target cell is sent to the base station, so that the base station reconfigures the handover target cell based on the specified measurement result.
In the embodiments of the present disclosure, when the terminal detects that the cell reconfiguration condition is met, it indicates that the first neighbor cell configured by the base station for the terminal is not the best. In this case, the terminal can send the specified measurement result for reconfiguring the handover target cell to the base station. In this way, the base station can select a best neighbor cell based on the specified measurement result reported by the terminal and reconfigure the neighbor cell for the terminal.
In an example scenario, as shown in
In the present disclosure, the base station 11 may be an apparatus deployed in an access network to provide wireless communication functionalities for the terminal 12. The base station 11 may include various types of macro base stations, micro base stations, relay stations, access points, and so on. In systems adopting different radio access technologies, names of devices having functionalities of a base station may be different. For example, in 5G NR systems, they are called gNodeB or gNB. As communication technology evolves, the name “base station” may change. For the convenience of description, in the embodiments of the present disclosure, apparatuses for providing wireless communication functionalities for the terminal 12 are collectively referred to as base stations.
Usually, there are a plurality of terminals 12, and one or more terminals 12 may be distributed in a cell managed by the base station 11. The terminals 12 may include various devices with wireless communication functionalities such as handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various types of User Equipment (UE for short), Mobile Station (MS for short), terminal device, etc. For ease of description, in the embodiments of the present disclosure, the above-mentioned devices are collectively referred to as terminals.
It can be seen from the above embodiment that after it is determined that the handover target cell configured by the base station for the terminal is the first neighbor cell, the cell reconfiguration condition can be determined, and when it is detected that the cell reconfiguration condition is met, it indicates that the first neighbor cell configured by the base station for the terminal is not a best handover target cell. In this case, the specified measurement result for reconfiguring the handover target cell may be sent to the base station, thus the base station can reconfigure the handover target cell based on the specified measurement result. In this way, it is ensured that the terminal can eventually perform a handover to the best neighbor cell, frequent handovers or a handover failure due to the terminal performing a handover to a cell with a weaker signal can be avoided and efficiency of cell handover is improved.
At step 310, it is detected that one or more second neighbor cells meet the cell reconfiguration condition.
In the embodiments of the present disclosure, the second neighbor cells represents neighbor cells that meet the first measurement report condition. If the terminal detects that one or more second neighbor cells are better than the first neighbor cell, the terminal can request the base station to reconfigure a handover target cell for it.
At step 320, measurement report information is generated, where the measurement report information includes respective identifiers of the second neighbor cells and respective first measurement results corresponding to the second neighbor cells.
In the embodiment of the present disclosure, the terminal informs the base station of respective first measurement results corresponding to the second neighbor cells, thus the base station can select a best neighbor cell from the second neighbor cells and reconfigure the neighbor cell for the terminal.
At step 330, the measurement report information is sent to the base station, so that the base station acquires the first measurement result from the measurement report information, where the first measurement result is the specified measurement result for reconfiguring the handover target cell.
The method for reconfiguring a cell shown in the steps 310 to 330 is described in the following specific examples, the base station 11 and terminal 12 shown in
In the embodiments of the present disclosure, since the signal strength of the neighbor cell 1 is greater than the signal strength of the neighbor cell 2, the base station may configure the neighbor cell 1 as the handover target cell.
In the embodiments of the present disclosure, since the signal strength of the neighbor cell 1 becomes weaker, and the signal strength of the neighbor cell 2 becomes stronger, and the signal strength of both meets the specified offset value of 3 db, the measurement report may be triggered in order to ensure that the terminal can perform a handover to a best neighbor cell. In this way, the base station can reconfigure the handover target cell for the terminal.
It can be seen from the above embodiment that when the cell reconfiguration condition includes the first measurement report condition, if it is detected that one or more second neighbor cells meet the cell reconfiguration condition, it indicates that the signal strength of the second neighbor cells is already greater than the signal strength of the first measurement report condition, that is, it indicate that the first neighbor cell configured by the base station for the terminal is not the best handover target cell, thus the base station is to reconfigure a handover target cell for the terminal from the second neighbor cells. In this case, the terminal can trigger the measurement report, that is, the terminal can generate measurement report information. The measurement report information includes respective identifiers of the second neighbor cells and respective first measurement results corresponding to the second neighbor cells. The measurement report information is sent to the base station, so that the base station can acquire the first measurement result from the measurement report information, and the handover target cell is reconfigured based on the first measurement result. In this way, frequent handovers due to the possibility of the terminal performing a handover to a cell with a weaker signal is avoided and the efficiency of cell handover is improved.
At step 410, the handover failure for the first neighbor cell is detected.
In the embodiments of the present disclosure, if the terminal initiates a handover to the first neighbor cell and the handover fails, the terminal may request the base station to reconfigure a handover target cell for it.
At step 420, handover failure indication information is generated, where the handover failure indication information includes an identifier of the first neighbor cell and second measurement results of other neighbor cells.
In the embodiments of the present disclosure, the terminal informs the base station of the second measurement results of the other neighbor cells, thus the base station can select a best neighbor cell from the other neighbor cells and reconfigure the neighbor cell for the terminal.
At step 430, the handover failure indication information is sent to the base station, so that the base station acquires the second measurement results from the handover failure indication information, where the second measurement results are the specified measurement result for reconfiguring the handover target cell.
The method for reconfiguring a cell shown in the steps 410 to 430 is described in the following specific examples, the base station 11 and terminal 12 shown in
In the embodiments of the present disclosure, since the signal strength of the neighbor cell 1 is greater than the signal strength of the neighbor cell 2, the base station may configure the neighbor cell 1 as the handover target cell.

The handover failure indication information includes an identifier of the first neighbor cell and second measurement results of other neighbor cells. The handover failure indication information is sent to the base station, so that the base station acquires the second measurement results from the handover failure indication information and reconfigures the handover target cell based on the second measurement results. In this way, when the handover fails, the terminal can initiate a handover to another handover target cell as soon as possible, and a time used for a cell handover is shortened, and realization of cell reconfiguration is enriched, thus improving reliability of cell reconfiguration.
At step 510, a reconfiguration message for indicating a third neighbor cell sent by the base station is received, where the third neighbor cell is the handover target cell reconfigured by the base station for the terminal.
In the embodiments of the present disclosure, the base station may take a neighbor cell with a greatest signal strength as a best neighbor cell and reconfigure the neighbor cell for the terminal.
At step 520, a handover is initiated to the third neighbor cell based on the reconfiguration message.
It can be seen from the above embodiment that when receiving a reconfiguration message for indicating a third neighbor cell sent by the base station, where the third neighbor cell is the handover target cell reconfigured by the base station for the terminal, a handover is initiated to the third neighbor cell based on the reconfiguration message. In this way, it is ensured that the terminal can eventually perform a handover to a best neighbor cell, and utility of the cell reconfiguration is improved.

In this case, the base station can select a best neighbor cell based on the specified measurement result reported by the terminal and reconfigure the neighbor cell for the terminal.
It can be seen from the above embodiment that when it is determined that the handover target cell configured for the terminal is the first neighbor cell, if the specified measurement result for reconfiguring the handover target cell sent by the terminal is received, the handover target cell can be reconfigured based on the specified measurement result. In this way, it is ensured that the terminal can eventually perform a handover to a best neighbor cell, frequent handovers or a handover failure due to the terminal performing a handover to a cell with a weaker signal can be avoided and the efficiency of cell handover is improved.
At step 710, when the terminal detects that one or more second neighbor cells meet the cell reconfiguration condition, measurement report information sent by the terminal is received. The measurement report information includes respective identifiers of the second neighbor cells and respective first measurement results corresponding to the second neighbor cells.
In the embodiments of the present disclosure, the second neighbor cells represent neighbor cells that meet the first measurement report condition. If the terminal detects that one or more second neighbor cells are better than the first neighbor cell, the terminal can request the base station to reconfigure a handover target cell for it.
At step 720, the first measurement result is acquired from the measurement report information, where the first measurement result is the specified measurement result for reconfiguring the handover target cell.
In the embodiments of the present disclosure, the terminal informs the base station of respective first measurement results corresponding to the second neighbor cells, thus the base station can select a best neighbor cell from the second neighbor cells and reconfigure the neighbor cell for the terminal.

In this case, the base station can acquire the first measurement result from the measurement report information, and the handover target cell is reconfigured based on the first measurement result. In this way, frequent handovers due to the possibility of the terminal performing a handover to a cell with a weaker signal is avoided and the efficiency of cell handover is improved.
At step 810, when the terminal detects the handover failure for the first neighbor cell, handover failure indication information sent by the terminal is received, where the handover failure indication information includes an identifier of the first neighbor cell and second measurement results of other neighbor cells.

In an example, the apparatus 2000 may be implemented by one or more Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components for performing the above method.
In an example, there is further provided a non-transitory computer readable storage medium including instructions, such as the memory 2002 including instructions. The above instructions may be executed by the processor 2009 of the apparatus 2000 to complete the above method. For example, the non-transitory computer readable storage medium may be a Read-Only Memory (ROM), a Random Access Memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.
When the instructions in the storage medium are executed by the processor, the apparatus is caused to perform any one of the above methods for reconfiguring a cell.
The present disclosure further provides an apparatus for reconfiguring a cell, the apparatus is applied to a base station and includes:
As shown in
A processor in the processing component 2122 may be configured to perform any one of the above methods for reconfiguring a cell.
The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects. In the present disclosure, after it is determined that the handover target cell configured by the base station for the terminal is the first neighbor cell, the cell reconfiguration condition can be determined, and when it is detected that the cell reconfiguration condition is met, it indicates that the first neighbor cell configured by the base station for the terminal is not a best handover target cell. In this case, the specified measurement result for reconfiguring the handover target cell may be sent to the base station, thus the base station can reconfigure the handover target cell based on the specified measurement result. In this way, it is ensured that the terminal can eventually perform a handover to the best neighbor cell, frequent handovers or a handover failure due to the terminal performing a handover to a cell with a weaker signal can be avoided and efficiency of cell handover is improved.
In the present disclosure, when it is determined that the handover target cell configured for the terminal is the first neighbor cell, if the specified measurement result for reconfiguring the handover target cell sent by the terminal is received, the handover target cell can be reconfigured based on the specified measurement result. In this way, it is ensured that the terminal can eventually perform a handover to a best neighbor cell, frequent handovers or a handover failure due to the terminal performing a handover to a cell with a weaker signal can be avoided and the efficiency of cell handover is improved.
