Abstract

The present invention relates to a wireless charging method, comprising: sending a wireless charging request to a network device for requesting the network device to provide a wireless charging configuration for the terminal, wherein the wireless charging request carries first auxiliary information, and the first auxiliary information at least indicates a wireless charging configuration expected by the terminal for assisting the network device to determine the wireless charging configuration.

Claims17

Dependent claims

A wireless charging method, performed by a terminal, wherein the method comprises:

sending, to a network device, a wireless charging request for requesting the network device to provide a wireless charging configuration for the terminal, in response to determining that a timing advance is less than a preset value;
wherein the wireless charging request carries first auxiliary information, and the first auxiliary information at least indicates a wireless charging configuration expected by the terminal for assisting the network device to determine the wireless charging configuration;
in response to the terminal leaving a wireless charging service area configured by the wireless charging configuration during a wireless charging process, sending leaving indication information to the network device to indicate that the terminal has left the wireless charging service area, wherein the leaving indication information further indicates whether the terminal expects to continue wireless charging after leaving the wireless charging service area, and carries location information of the terminal in response to the terminal expects to continue the wireless charging;
in response to that the terminal is in a connected state or an unconnected state,
sending expectation indication information to the network device to indicate whether the terminal expects to continue wireless charging after entering the unconnected state;
wherein the terminal expects to continue wireless charging after entering the unconnected state, and the method further comprises:
receiving unconnected-state wireless charging configuration information sent by the network device, determining an unconnected-state wireless charging service area according to the unconnected-state wireless charging configuration information, and
after entering the unconnected state, receiving a wireless charging signal to perform wireless charging while being in the unconnected-state wireless charging service area.

A wireless charging method, performed by a network device, wherein the method comprises:

receiving a wireless charging request sent by a terminal, wherein the wireless charging request is used for requesting to provide a wireless charging configuration for the terminal, and the wireless charging request carries first auxiliary information which at least indicates a wireless charging configuration expected by the terminal for assisting the network device to determine the wireless charging configuration;
and the wireless charging request is sent by the terminal in response to that a timing advance is less than a preset value;
receiving leaving indication information sent by the terminal, and determining that the terminal has left a wireless charging service area according to the leaving indication information;
determining, according to the leaving indication information, whether the terminal expects to continue wireless charging after the terminal leaves the wireless charging service area, and determining location information of the terminal according to the leaving indication information in response to determining that the terminal expects to continue wireless charging;
in response to that the terminal is in a connected state or an unconnected state, receiving expectation indication information sent by the terminal, and determining, according to the expectation indication information, whether the terminal expects to continue wireless charging after the terminal enters the unconnected state;
wherein in response to determining that the terminal expects to continue wireless charging after the terminal enters the unconnected state, the method further comprises:
sending unconnected-state wireless charging configuration information to the terminal, wherein an unconnected-state wireless charging service area is carried in the unconnected-state wireless charging configuration information.

4 more elements

A wireless charging apparatus, wherein the apparatus comprises one or more processors configured to:

send to a network device a wireless charging request for requesting the network device to provide a wireless charging configuration for a terminal, in response to determining that a timing advance is less than a preset value;
wherein the wireless charging request carries first auxiliary information, and the first auxiliary information at least indicates a wireless charging configuration expected by the terminal for assisting the network device to determine the wireless charging configuration;
in response to the terminal leaving a wireless charging service area configured by the wireless charging configuration during a wireless charging process, send leaving indication information to the network device to indicate that the terminal has left the wireless charging service area, wherein the leaving indication information further indicates whether the terminal expects to continue wireless charging after leaving the wireless charging service area, and carries location information of the terminal in response to the terminal expects to continue the wireless charging;
in response to that the terminal is in a connected state or an unconnected state,
send expectation indication information to the network device to indicate whether the terminal expects to continue wireless charging after entering the unconnected state;
wherein in response to determining that the terminal expects to continue wireless charging after entering the unconnected state, and the wireless charging apparatus is further configured to:
receive unconnected-state wireless charging configuration information sent by the network device, determine an unconnected-state wireless charging service area according to the unconnected-state wireless charging configuration information, and
after the terminal entering the unconnected state, receive a wireless charging signal to perform wireless charging while being in the unconnected-state wireless charging service area.
