Detailed Description
The following embodiments of the present invention provide a method and an apparatus for controlling UE wireless charging, and RAN equipment.
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of an embodiment of a method for controlling UE wireless charging according to the present invention is shown:
step 101: the RAN equipment receives a wireless charging command sent by CN equipment, wherein the wireless charging command is a command generated by the CN equipment according to a wireless charging request message sent by UE.
In the embodiment of the invention, when the UE detects that the electric quantity of the UE is insufficient, the UE can send the wireless charging request message to the CN equipment. When the UE is in the RRC idle state, the UE establishes RRC connection with the CN equipment and then sends the wireless charging request message to the CN equipment. The wireless charging request message sent by the UE may be transmitted to the CN device through the RAN device, and after receiving the wireless charging request message, the CN device may authenticate the UE, and when confirming that the UE can perform wireless charging, may send a wireless charging command to the RAN device.
Step 102: the RAN equipment selects a first wireless charging node for the UE according to the wireless charging command.
And after receiving the wireless charging command sent by the CN equipment, the RAN equipment selects a first wireless charging node for the UE. In the embodiment of the present invention, the wireless charging node accessed to the RAN device may be a base station where the UE is located, a Relay station Relay, a Radio Remote Unit (RRU), a small cell, a micro base station (pico), and the like, where the wireless charging node is an entity to which the UE cannot be directly accessed or cannot be directly perceived, but the charging nodes may be perceived by the RAN device and may be controlled by the RAN device.
When the RAN equipment selects a wireless charging node for the UE from a plurality of wireless charging nodes, the RAN equipment firstly obtains the position information of the UE under the trigger of a received wireless charging command, and selects a wireless charging node closest to the UE for the UE according to the position information of the UE and the position information of each wireless charging node. When obtaining the location information of the UE, the RAN device may obtain the location information of the UE from a measurement report reported by the UE, or the RAN device may also obtain the location information of the UE through GPS positioning, which is not limited in the embodiments of the present invention.
Step 103: the RAN equipment controls the first wireless charging node to be started so that the first wireless charging node can charge the UE.
After the RAN device selects the first wireless charging node for the UE, the RAN device may control the wireless charging transmitter of the first wireless charging node to start, and correspondingly, the wireless charging receiver of the UE to start, so as to wirelessly charge the UE through the first wireless charging node.
As can be seen from the above embodiments, in the embodiment, the mobility management performance of the wireless communication network for the UE is applied, and the RAN device is used to control and manage the wireless charging of the UE, so that the RAN device can select different wireless charging nodes for the UE during the moving process of the UE, thereby ensuring that the wireless charging of the UE is not interrupted, thereby achieving the seamless performance of the wireless charging and improving the mobile charging experience of the user.
Referring to fig. 2, a flowchart of another embodiment of the method for controlling UE wireless charging according to the present invention shows a process that RAN equipment reselects a wireless charging node for a UE and charges the UE when the UE is in an RRC connected state:
step 201: the UE is in RRC connected state.
In the embodiment of the invention, when the UE detects that the electric quantity of the UE is insufficient, the UE can send the wireless charging request message to the CN equipment. For example, the UE may set the wireless charging request message to be sent to the CN device when the power is less than 20%. The UE needs to send the wireless charging request message in an RRC connected state, so before sending the wireless charging request message, if the UE has service transmission with the network side, the UE already enters the RRC connected state, or if there is no service transmission between the UE and the network side, the CN device has released the RRC connection for the UE, the UE is in an RRC idle state, and at this time, the UE needs to reestablish the RRC connection with the CN device and enter the RRC connected state.
Step 202: the UE sends a wireless charging request message to the CN device.
In this embodiment, the wireless charging request message sent by the UE in the RRC connected state may be transmitted to the CN device through the RAN device.
The wireless charging request message may be carried by a Non-Access stratum (NAS) message, or may be carried by a newly established message, which is not limited in this embodiment of the present invention.
Step 203: the CN device sends a wireless charging command to the RAN device.
Optionally, if the UE subscribes to the wireless charging service in advance, the CN device may send the wireless charging command to the RAN device after receiving the wireless charging request message and determining that the UE is a subscriber of the wireless charging service according to the wireless charging request message.
Optionally, after receiving the wireless charging command, the RAN device may issue first wireless charging private control information to the UE, where the control information may be carried in the wireless charging command issued by the CN device or generated by the RAN device. For example, the wireless charging private control information may include an unlocking command for a wireless charging receiver built in the UE, so as to ensure that only the UE receiving the unlocking command can be charged through the wireless charging node selected by the subsequent RAN device, and other UEs that do not receive the unlocking command cannot be charged even within the charging range of the wireless charging node.
Step 204: the RAN equipment selects a first wireless charging node for the UE according to the wireless charging command and controls the first wireless charging node to be started.
And after receiving the wireless charging command sent by the CN equipment, the RAN equipment selects a first wireless charging node for the UE. In the embodiment of the present invention, the wireless charging node accessed to the RAN device may be a base station, a Relay station Relay, an RRU, a small base station, a micro base station (pico), and the like, where the UE is located, and the wireless charging node is an entity that the UE cannot be directly accessed or directly perceived, but the charging nodes may be perceived by the RAN device and may be controlled by the RAN device.
When the RAN device selects a wireless charging node for the UE from the plurality of wireless charging nodes, the RAN device may first obtain location information of the UE, and select a wireless charging node closest to the UE for the UE according to the location information of the UE and the location information of each wireless charging node. When obtaining the location information of the UE, the RAN device may obtain the location information of the UE from a measurement report reported by the UE, or the RAN device may also obtain the location information of the UE through GPS positioning, which is not limited in the embodiments of the present invention.
After the RAN device selects the wireless charging node for the UE, the RAN device controls the wireless charging transmitter of the wireless charging node to start, so as to wirelessly charge the UE through the wireless charging node, and the wireless charging process is consistent with the prior art and is not described herein again.
On the basis of the embodiment shown in the above steps 201 to 204, another embodiment of the present invention may further perform the following steps 205 to 206, which show the process of reselecting the charging node for the UE when the UE moves.
Step 205: the RAN equipment senses location change information of the UE.
In the process of charging the UE by the first wireless charging node, if the UE moves out of the range of the current first wireless charging node, the RAN device may perceive the location change information of the UE according to the location information of the UE obtained in real time, where a manner of obtaining the location information of the UE by the RAN device in real time is consistent with the description in step 204, and is not described herein again.
Step 206: and the RAN equipment selects a second wireless charging node for the UE again according to the position change information, controls the first wireless charging node to be closed, and controls the second wireless charging node to be opened.
The RAN device reselects the second wireless charging node for the UE according to the location change information of the UE, and the selection process is consistent with the description of step 204, and is not described herein again. After the RAN equipment selects the second wireless charging node, the RAN equipment controls the second wireless charging node to be started, and controls the first wireless charging node to be stopped at the same time, so that the second wireless charging node replaces the first wireless charging node to charge the UE, and seamless charging in the moving process of the UE is achieved.
As can be seen from the above embodiments, in the embodiment, the mobility management performance of the wireless communication network for the UE is applied, and the RAN device is used to control and manage the wireless charging of the UE, so that the RAN device can select different wireless charging nodes for the UE during the moving process of the UE, thereby ensuring that the wireless charging of the UE is not interrupted, thereby achieving the seamless performance of the wireless charging and improving the mobile charging experience of the user.
Referring to fig. 3, a flowchart of another embodiment of the method for controlling UE wireless charging according to the present invention shows a process that RAN equipment reselects a wireless charging node for a UE and charges the UE when the UE is in an RRC idle state:
step 301: the UE is in RRC connected state.
In the embodiment of the invention, when the UE detects that the electric quantity of the UE is insufficient, the UE can send the wireless charging request message to the CN equipment. For example, the UE may set the wireless charging request message to be sent to the CN device when the power is less than 20%. The UE needs to send the wireless charging request message in an RRC connected state, so before sending the wireless charging request message, if the UE has service transmission with the network side, the UE already enters the RRC connected state, or if there is no service transmission between the UE and the network side, the CN device has released the RRC connection for the UE, the UE is in an RRC idle state, and at this time, the UE needs to reestablish the RRC connection with the CN device and enter the RRC connected state.
Step 302: the UE transmits wireless charging request information to the CN device.
In this embodiment, the wireless charging request message sent by the UE in the RRC connected state may be transmitted to the CN device through the RAN device.
The wireless charging request message may be carried by an NAS message, or may also be carried by a newly established message, which is not limited in this embodiment of the present invention.
Step 303: the CN device sends a wireless charging command to the RAN device.
Optionally, if the UE subscribes to the wireless charging service in advance, the CN device may send the wireless charging command to the RAN device after receiving the wireless charging request message and determining that the UE is a subscriber of the wireless charging service according to the wireless charging request message.
Optionally, after receiving the wireless charging command, the RAN device may issue first wireless charging private control information to the UE, where the control information may be carried in the wireless charging command issued by the CN device or generated by the RAN device. For example, the wireless charging private control information may include an unlock command to a wireless charging receiver built in to the UE.
Step 304: the RAN equipment selects a first wireless charging node for the UE according to the wireless charging command and controls the first wireless charging node to be started.
And after receiving the wireless charging command sent by the CN equipment, the RAN equipment selects a first wireless charging node for the UE. In the embodiment of the present invention, the wireless charging node accessed to the RAN device may be a base station, a Relay station Relay, an RRU, a small base station, a micro base station (pico), and the like, where the UE is located, and the wireless charging node is an entity that the UE cannot be directly accessed or directly perceived, but the charging nodes may be perceived by the RAN device and may be controlled by the RAN device.
When the RAN device selects a wireless charging node for the UE from the plurality of wireless charging nodes, the RAN device may first obtain location information of the UE, and select a wireless charging node closest to the UE for the UE according to the location information of the UE and the location information of each wireless charging node. When obtaining the location information of the UE, the RAN device may obtain the location information of the UE from a measurement report reported by the UE, or the RAN device may also obtain the location information of the UE through GPS positioning, which is not limited in the embodiments of the present invention.
After the RAN device selects the wireless charging node for the UE, the RAN device controls the wireless charging transmitter of the wireless charging node to start, so as to wirelessly charge the UE through the wireless charging node, and the wireless charging process is consistent with the prior art and is not described herein again.
On the basis of the embodiments shown in the above steps 301 to 304, another embodiment of the present invention may further perform the following steps 305 to 310, which show the process that when the UE has no traffic transmission, the UE status changes and the charging node is selected again for the UE.
Step 305: when the UE has no service transmission, the CN equipment triggers the UE to carry out RRC release, and then the UE enters an RRC idle state.
The embodiment is different from the embodiment shown in fig. 2 in that if there is no service transmission between the UE and the network side in the process of charging the UE by the first wireless charging node, the CN device triggers the UE to perform RRC release, and the UE enters an RRC idle state.
Step 306: the UE detects that the charging efficiency is below a threshold.
When the UE is in the RRC idle state, the UE may perform cell reselection measurement, monitor a charging condition of the UE by a current first wireless charging node, and when the UE moves and moves out of a range of the first wireless charging node, at this time, since the UE is in the RRC idle state, the RAN device cannot sense location change information of the UE, but since the UE moves out of the range of the first wireless charging node, the UE may detect that the charging efficiency is reduced until the charging efficiency is lower than a preset threshold.
Step 307: and establishing RRC connection between the UE and the CN equipment, and enabling the UE to enter an RRC connection state.
When the UE detects that the charging efficiency is lower than the preset threshold value, it indicates that the RAN equipment needs to select the wireless charging node for the UE again, at this time, the UE triggers the establishment of RRC connection with the CN equipment, and the UE enters an RRC connection state.
Step 308: and the UE reports the wireless charging information to the RAN equipment.
After the UE establishes the RRC connection, it may report wireless charging information to the RAN device through the RRC connection, where the wireless charging information may include current location information of the UE, and further may include neighboring cell measurement information and current power information of the UE. The wireless charging information may be carried by an RRC message, or a Media Access Control (MAC) Control Element (CE), or may be carried by a newly established message, which is not limited in this embodiment of the present invention.
Step 309: and the RAN equipment reselects a third wireless charging node for the UE according to the wireless charging information, controls the first wireless charging node to be closed, and controls the third wireless charging node to be opened.
The RAN device reselects the third wireless charging node for the UE according to the location information of the UE included in the wireless charging information, and the selection process is consistent with the description of step 304, and is not described herein again. And after the RAN equipment selects the third wireless charging node, controlling the third wireless charging node to be started, and simultaneously controlling the first wireless charging node to be closed, so that the third wireless charging node replaces the first wireless charging node to charge the UE, and seamless charging in the moving process of the UE is realized.
Step 310: and the RAN equipment triggers the UE to release the RRC, and the UE reenters the RRC idle state.
In this embodiment, since the RAN device is in the RRC idle state before reselecting the wireless charging node for the UE, after the RAN device reselects the third wireless charging node for the UE, the RAN device may trigger the UE to perform RRC release, so that the UE recovers to the previous RRC idle state.

Referring to fig. 4, a flowchart of another embodiment of the method for controlling UE wireless charging according to the present invention shows a RAN device control process after the UE completes wireless charging:
step 401: the UE detects that the charging is complete.
In this embodiment, the UE may preset a charging completion value, for example, when the power of the UE exceeds 95%, the UE detects that charging is completed.
Step 402: the UE enters the RRC connected state.
Wherein, the UE may be in an RRC connected state all the time during the charging process; or, the UE may be in the RRC idle state during the charging process, and when the UE detects that the charging is completed, the UE reestablishes the RRC connection with the CN device and enters the RRC connected state.
Step 403: and the UE sends a wireless charging completion message to the CN equipment.
In this embodiment, a wireless charging completion message sent by the UE in the RRC connected state may be transmitted to the CN device through the RAN device, where the wireless charging completion message may include information of a charged amount of the UE.
The wireless charging completion message may be carried by a Non-Access stratum (NAS) message, or may be carried by a newly established message, which is not limited in this embodiment of the present invention.
Step 404: the CN device sends a wireless charging completion command to the RAN device.
Optionally, in the embodiments shown in fig. 2 and fig. 3, if the RAN device issues the first wireless charging private control information to the UE after receiving the wireless charging command, the RAN device may issue the second wireless charging private control information to the UE after receiving the wireless charging completion command, where the control information may be carried in the wireless charging completion command issued by the CN device, or may be generated by the RAN device. For example, the second wireless charging private control information may include a lock command to a wireless charging receiver built in to the UE.
Step 405: the RAN device turns off the wireless charging node that charges the UE.
As can be seen from the above embodiments, the embodiment applies the mobility management performance of the wireless communication network to the UE, and after the UE is charged, the wireless charging node can be controlled to be turned off, so as to implement control and management of the wireless charging process, and ensure that the wireless charging node in the wireless network can flexibly provide charging service for the mobile UE.
