Patent Description:
Along with technology development of drones, drones have played an important role in various fields, for example, aerial photography, express transportation, disaster relief and news report. After a drone accesses a cell and is in a connected state, if another cell is detected, and a signal of the another cell keeps being stronger than a signal of the presently-accessed cell by a threshold value within a preset time period (usually called TimeToTrigger), the drone performs cell handover processing and is handed over from the presently-accessed cell to the another cell.

In order to describe the technical solutions in the embodiments of the present disclosure more clearly, the accompanying drawings required to be used for descriptions about the embodiments will be simply introduced below. It is apparent that the accompanying drawings described below only illustrate some embodiments of the present disclosure. Those skilled in the art may further obtain other accompanying drawings according to these accompanying drawings without creative work.

A method for managing a measurement parameter for cell handover is provided according to an exemplary embodiment of the present disclosure. The method may be implemented by a flight vehicle. The flight vehicle may be an unmanned helicopter, an unmanned airship and the like.

The flight vehicle may include components such as a processor, a memory, a transceiver and a flight component. The processor may be a Central Processing Unit (CPU) and the like, and may be configured for related processing for calculation of a target measurement parameter. The transceiver may be configured to receive correspondences between target parameters and measurement parameters for cell handover sent by a base station and the like. The memory may be a Random Access Memory (RAM), a flash and the like, and may be configured to store received data, data required in a processing process, data generated in the processing process and the like, for example, the correspondences between the target parameters and the measurement parameters for cell handover. The flight component may include a motor, a propeller and the like. The motor is configured to provide flight power, and the propeller is configured to drive an airflow to implement flight of the flight vehicle.

A method for managing a measurement parameter for cell handover is provided according to an embodiment of the present disclosure. As shown in <FIG>, the method includes steps as follows.

In step <NUM>, a target parameter is acquired in a flight process. The target parameter is a parameter varying with an altitude and configurable to indicate the altitude of a flight vehicle.

In implementation, the flight vehicle detects the target parameter in the flight process to acquire the target parameter, for subsequently determining a measurement parameter for cell handover.

In step <NUM>, a target measurement parameter for cell handover is determined according to the target parameter.

The measurement parameter for cell handover is used to determine cell handover. When a device (the flight vehicle or another terminal) detects that signal strength of a cell meets a cell handover condition in a time period, and a duration of the time period reaches the measurement parameter, cell handover is performed.

In implementation, the flight vehicle, after acquiring the target parameter, determines the target measurement parameter for cell handover according to the target parameter.

In step <NUM>, cell handover processing is performed according to the target measurement parameter.

In implementation, the flight vehicle, after determining the target measurement parameter, judges whether the flight vehicle is required to perform cell handover and performs related processing.

A method for managing a measurement parameter for cell handover is provided according to an embodiment of the present disclosure. A measurement parameter comprises a TimeToTrigger, a Hysteresis parameter (Hys) or the like. The TimeToTrigger is taken as an example of the measurement parameter in the embodiment, to describe the solution in detail. The other cases for the method are similar to the case for the TimeToTrigger, and will not be described repeatedly in the embodiment anymore. As shown in <FIG>, the method for managing a measurement parameter for cell handover may include the following steps.

In step <NUM>, a first notification message sent by a base station is received. The first notification message is used to instruct a flight vehicle to detect a target parameter.

In implementation, the base station may record in advance the target parameter which is to be detected by the flight vehicle, and a parameter used as the target parameter may be pre-configured by a technician. After the flight vehicle accesses the base station, the base station sends the first notification message to the flight vehicle, as shown in <FIG>, for example, Radio Resource Control (RRC) signaling. The first notification message instructs the flight vehicle to detect the target parameter. The flight vehicle, after receiving the first notification message, parses the first notification message to obtain the type of the target parameter to be detected by the flight vehicle, and then the flight vehicle may measure the target parameter to obtain the target parameter.

In step <NUM>, the target parameter is acquired in a flight process. The target parameter is a parameter varying with an altitude and configurable to indicate the altitude of the flight vehicle.

In implementation, when a user is intended to control the flight vehicle to take off, the user may place the flight vehicle stably, turn on a switch of the flight vehicle, operate a remote controller to control the flight vehicle to fly, and control a flight direction of the flight vehicle. The flight vehicle, after being turned on and receiving a signal of the base station, may further establish a connection with the base station. The flight vehicle, after successfully accessing the base station, may detect the parameter at a preset detection period. Every time when the preset detection period is reached, the flight vehicle may measure the target parameter, for subsequently determining the TimeToTrigger for cell handover.

The target parameter may be one or more of a parameter on an altitude value, a parameter on the number of detected cells other than a presently-accessed cell, a parameter on the number of detected cells, other than the presently-accessed cell and neighbor cells thereof, and a parameter on an increase speed of the number of detected cells.

The parameter on the increase speed of the number of cells refers to an increment of the number of detected cell per height unit rise of the flight vehicle.

In implementation, the target parameter may be represented in many manners.

In a first condition that the target parameter is a parameter on an altitude value, the operation that the flight vehicle detects the target parameter may include an operation as follows. The flight vehicle may measure an altitude (in meters) at a present position through a laser ranging or <NUM> Dimensions (3D) Global Positioning System (GPS), as shown in <FIG>, to obtain a value as the detected target parameter.

The target parameter is the parameter on the number of detected cells other than the presently-accessed cell, the operation that the flight vehicle detects the target parameter may include an operation as follows. The base station may periodically broadcast a synchronization signal and a secondary synchronization signal to each cell. The synchronization signal and the secondary synchronization signal contain a cell identifier. Since signal coverage of different cells may overlap, signals of multiple cells may be detected by the flight vehicle at the same time (within a relatively short preset time). The flight vehicle acquires the cell identifier from each presently-detected signal, as shown in <FIG>, and calculates the number of cell identifiers of cells other than the presently-accessed cell as the detected target parameter. Alternatively, when the number of cell identifiers is calculated, only the number of cell identifiers carried in messages having signal strength greater than a preset threshold value is calculated.

In a third condition that the target parameter is the parameter on the number of detected cells, other than the presently-accessed cell and the neighbor cells of the presently-accessed cell, the operation that flight vehicle detects the target parameter may include operations as follows. A server may obtain the cell identifier acquired by the flight vehicle from each presently-detected message according to a processing manner in the above second condition, then acquire a list of neighbor cells of the currently-accessed cell, compare all the cell identifiers detected by the flight vehicle with cell identifies in the list of the neighbor cells, remove a cell identifier in the list of the neighbor cells and the cell identifier of the presently-accessed cell from all the cell identifiers, calculate the number of remaining cell identifiers as the detected target parameter. The list of neighbor cells of the currently-accessed cell may be pre-stored by the flight vehicle, and may also be sent to the flight vehicle by the base station and then received and stored by the flight vehicle.

In a fourth condition that the target parameter is the parameter on an increase speed of the number of detected cells, the operation that the flight vehicle detects the target parameter may include operations as follows. As shown in <FIG>, the server may detect the altitude of the flight vehicle according to a processing manner in the first condition. Every time when the flight vehicle rises by a unit height, the flight vehicle obtains the number of cells that may be detected at the same time in a processing manner similar to the above second condition, records the number of cells, and acquires the number of cells detected at the previous unit height, further calculates an increment of the number of cells after rising by the unit height, and divides the increment by the unit height to obtain an increase speed as the detected target parameter.

In the embodiment of the present disclosure, one or a combination of the above conditions may be used, that is, the target parameter may be any one or more of the above conditions.

In step <NUM>, a target TimeToTrigger for cell handover is determined according to the target parameter.

The TimeToTrigger for cell handover is configured to determine cell handover. When a device (the flight vehicle or another terminal) detects that signal strength of a cell always meets a cell handover condition within a time period, and a duration of the time period reaches the TimeToTrigger, cell handover is performed. In correspondences, for the condition that the target parameter is the parameter on the altitude value, the TimeToTrigger increases with an increase of the altitude; in the condition that the target parameter is the parameter on the number of detected cells other than the presently-accessed cell, the TimeToTrigger increases with an increase of the number; for the condition that the target parameter is the parameter on the number of detected cells, other than the presently-accessed cell and the neighbor cells thereof, the TimeToTrigger increases with an increase of the number; and for the condition that the target parameter is the parameter on an increase speed of the number of detected cells, the TimeToTrigger increases with an increase of the increase speed.

As shown in <FIG>, the method includes step <NUM>', in which, a target regulation factor corresponding to the currently-acquired target parameter is determined according to pre-stored correspondences between target parameters and regulation factors; and a product of the target regulation factor and a pre-stored reference TimeToTrigger for cell handover is acquired to obtain the target TimeToTrigger for cell handover.

In implementation, reference TimeToTrigger may be preset by the technician, or may be arbitrarily set based on a practical condition. For example, the reference TimeToTrigger may be set in consideration of a cell density. In addition, correspondences between the target parameters and the regulation factors may also be preset by the technician, and may be stored in form of a table. A value of the regulation factor may be arbitrarily set based on the practical condition, and may be set in consideration of the selected target parameter. The reference TimeToTrigger and the correspondences table may be directly stored in a memory of the flight vehicle, and may also be sent to the flight vehicle by the base station and stored in the flight vehicle. In the above correspondences, for the condition that the target parameter is the parameter on the altitude value, the regulation factor increases with an increase of the altitude; for the condition that the target parameter is the parameter on the number of detected cells other than the presently-accessed cell, the regulation factor increases with an increase of the number; for the condition that the target parameter is the parameter on the number of detected cells, other than the presently-accessed cell and the neighbor cells thereof, the regulation factor increases with an increase of the number; and for the condition that the target parameter is the parameter on the increase speed of the number of detected cells, the regulation factor increases with an increase of the increase speed.

The flight vehicle, after detecting the target parameter, search the correspondence table for a regulation factor (i.e., the target regulation factor) corresponding to the value. The target regulation factor is multiplied by the reference TimeToTrigger to obtain a product as the target TimeToTigger.

For example, the preset reference TimeToTrigger is <NUM>,<NUM>, and the correspondence table of the target parameters and the regulation factors is shown in Table <NUM>.

When the target parameter is the parameter on the altitude value and the flight vehicle detects that the altitude is <NUM> meters, it may be learned according to Table <NUM> that the regulation factor corresponding to the target parameter is <NUM> when the target parameter is <NUM> meters, and the regulation factor of <NUM> is multiplied by the reference TimeToTrigger <NUM>,<NUM>, <NUM> × <NUM>=<NUM>, to obtain <NUM>. Therefore, it may be learned that the target TimeToTrigger corresponding to the present position of the flight vehicle is <NUM>,<NUM>.

For another example, the preset reference TimeToTrigger is <NUM>, and the correspondence table between the target parameters and the regulation factors is shown in Table <NUM>.

When the target parameter is the parameter on the number of detected cells other than the presently-accessed cell and the flight vehicle detects that the number of detected cells is <NUM>, it may be learned according to Table <NUM> that the regulation factor corresponding to the target parameter is <NUM> when the target parameter is <NUM>, and the regulation factor <NUM> is multiplied by the reference TimeToTrigger <NUM>, <NUM> × <NUM>=<NUM>, to obtain <NUM>. Therefore, it may be learned that the target TimeToTrigger corresponding to the present position of the flight vehicle is <NUM>,<NUM>.

Optionally, as shown in <FIG>, the method further includes step <NUM>, in which, a second notification message sent by the base station is received, the second notification message contains the reference TimeToTrigger and the correspondences between the target parameters and the regulation factors, and the correspondences and the reference TimeToTrigger are stored.

The second notification message and the first notification message may be the same message, and may also be different messages.

In implementation, correspondences between the target parameters and the regulation factors may be preset by the technician, and be stored in the base station in form of a table. In addition, the reference TimeToTrigger may also be preset by the technician, and be stored in the base station. When the flight vehicle accesses the base station, the base station may send the second notification message to the flight vehicle, the second notification message contains the correspondences and the reference TimeToTrigger. The flight vehicle, after receiving the second notification message sent by the base station, stores the reference TimeToTrigger and the correspondences between the target parameters and the regulation factors and in the second notification message, for subsequently calculating the target TimeToTrigger.

In step <NUM>, cell handover processing is performed according to the target TimeToTrigger.

In implementation, the flight vehicle, after determining the target TimeToTrigger, stores the target TimeToTrigger. If the flight vehicle detects that a difference between signal strength of a cell and signal strength of the presently-accessed cell is greater than a preset threshold value, and a duration in which the difference is kept greater than the preset threshold value reaches the target TimeToTrigger, a drone starts executing cell handover processing and is handed over from the presently-accessed cell to the cell having relatively high signal strength, as shown in <FIG>. A value of the preset threshold value may range from 5dBm to 20dBm. For example, the preset threshold value is 10dBm.

In the embodiment of the present disclosure, the target parameter is acquired, the target parameter is a parameter varying with the altitude and configurable to indicate the altitude of the flight vehicle. The target TimeToTrigger for cell handover is determined according to the target parameter. Cell handover processing is performed according to the target TimeToTrigger. In such a manner, the drone may have different TimeToTrigger at different heights. Based on values set in the correspondences, a relatively long TimeToTrigger is obtained when the drone flies at a relatively high height, which avoids frequent cell handover, thereby reducing a failure rate of data transmission.
