Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with embodiments of the invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of embodiments of the invention, as detailed in the following claims.

The terminology used in the embodiments of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of the present disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of embodiments of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The execution subject that this disclosed embodiment relates to includes but not limited to: a wireless charging transmitting terminal, such as a wireless charging base; and a wireless charging receiving end, such as a mobile phone.

An application scenario of the embodiment of the present disclosure is, as shown in fig. 1, that a charging coil of a wireless charging transmitting terminal generates electromagnetic induction through faraday's law to transfer energy to the charging coil of a wireless charging receiving terminal. The wireless charging transmitting terminal and the wireless charging receiving terminal adopt the wave beam with the same frequency as the wireless charging wave beam as a carrier wave, or directly adopt the charging wave beam as the carrier wave to carry out in-band communication. Thus, in-band communication interferes with the wireless charging beam to reduce charging efficiency.

As shown in fig. 2, the present exemplary embodiment provides a wireless charging authentication method, where the wireless charging authentication method may be applied to a wireless charging receiving terminal, and the wireless charging authentication method may include:

step 201: receiving indication information;

step 202: and responding to the fact that the wireless charging transmitting terminal supports out-of-band communication determined according to the indication information, and authenticating the wireless charging based on the out-of-band communication.

Here, the wireless charging receiving terminal may be a power receiving device supporting the Qi wireless charging standard, for example, a mobile phone supporting wireless charging. The wireless charging transmitting terminal may be a power supply device indicating the Qi wireless charging standard, e.g. a charger supporting wireless charging or the like. Of course, this embodiment is not limited to the Qi wireless charging standard, and may also be adapted to a powered device supporting other standards in the evolution of the standard.

The in-band communication may be communication in which the carrier wave has the same frequency band as the charging beam, or signal transmission is performed directly using the charging beam as the carrier wave. For example, in-band communication may load information on a charging beam through amplitude modulation or frequency shift keying modulation, and perform signal transmission through a charging coil of a wireless charging transmitter and a charging coil of a wireless charging receiver.

The out-of-band communication may be communication using a carrier different from the band of the charging beam for signal transmission. For example: the out-of-band communication may be bluetooth, near field communication, WiFi, and the like. Here, the bluetooth may include bluetooth low energy, and the like. Because the carrier wave of the in-band communication and the charging wave beam have the same frequency band, the interference is generated on the charging wave beam, and the charging efficiency is reduced; or, since the modulated signal is loaded on the charging beam, the stability of the wireless charging voltage is reduced, and the charging efficiency is reduced.

Here, the authentication of the wireless charging refers to a mutual authentication process between the wireless charging transmitting terminal and the wireless charging receiving terminal based on the Qi wireless charging standard. The wireless charging receiving end can determine whether the wireless charging receiving end is a powered device meeting the wireless charging requirement or not through the authentication wireless charging transmitting end of the wireless charging, and a wireless charging protocol and the like which can be adopted by the wireless charging receiving end. Here, the wireless charging protocol may include a Basic Power Profile (BPP) protocol, an Extended Power Profile (EPP) protocol, and the like.

The wireless charging transmitting terminal can send the indication information after establishing communication connection with the wireless charging receiving terminal. The wireless charging transmitting terminal can send the indication information in the initialization process after the communication connection is established. Here, the communication connection may be a communication connection established by in-band communication or a communication connection established by out-of-band communication.

The wireless charging transmitting terminal can send the indication information when the wireless charging receiving terminal is close to the wireless charging transmitting terminal. When the wireless receiving terminal that charges was close to the wireless transmitting terminal that charges, the load of the charging coil of the wireless transmitting terminal that charges can send the change, consequently, the wireless transmitting terminal that charges can confirm whether the wireless transmitting terminal that charges is close to according to the load condition of charging coil.

The indication information may include an indication of whether the wireless charging transmitting terminal supports out-of-band communication. Here, whether the wireless charging transmitting terminal supports out-of-band communication may include: whether the wireless charging transmitting terminal supports the wireless charging out-of-band communication and/or whether the wireless charging transmitting terminal supports the wireless charging authenticated out-of-band communication.

For example, the support information may indicate whether the wireless charging transmitting terminal supports out-of-band communication with 1 bit, for example: support may be represented by "1" and not support by "0"; support may also be indicated by "0" and not by "1".

When the charging coil was used for charging, the charging coil of wireless transmitting terminal that charges and the charging coil of the wireless receiving terminal that charges produced electromagnetic induction transmission energy through Faraday's law. When the charging coil is used for in-band communication, the charging coil of wireless transmitting terminal that charges and the charging coil of wireless receiving terminal that charges are regarded as communication antenna, send or receive modulation electromagnetic signal. The in-band communication is limited by the charging coil due to the fact that the charging coil is multiplexed with the wireless charging coil, and the in-band communication is carried out in an amplitude modulation or frequency shift keying modulation mode, so that the anti-interference performance is poor, and the transmission rate is low; on the other hand, the efficiency of wireless charging is affected when in-band communication is adopted for communication; thereby affecting the user experience.

The wireless charging receiving end can determine whether the wireless charging transmitting end supports out-of-band communication according to the supporting information; when the wireless charging transmitting terminal supports out-of-band communication, the out-of-band communication can be selected for authentication of wireless charging.

Thus, the wireless charging transmitting terminal can indicate whether the out-of-band communication is supported or not through the indication information. When the wireless charging transmitting terminal supports out-of-band communication, the wireless charging receiving terminal can select out-of-band communication to perform authentication of wireless charging according to the indication of the indication information, on one hand, compared with in-band communication, the transmission rate of the out-of-band communication is high, the communication delay can be reduced, and the user experience is improved; on the other hand, the authentication of the wireless charging and the wireless charging adopt different communication modes, the wireless charging is not influenced by the authentication of the wireless charging, and the efficiency of the wireless charging is improved.

In one embodiment, step 202 may comprise:

and responding to the fact that the wireless charging transmitting end supports out-of-band communication and the wireless charging receiving end supports out-of-band communication of the same type according to the indication information, and authenticating wireless charging through the out-of-band communication supported by the wireless charging transmitting end and the wireless charging receiving end.

The indication information may include an indication of a type of out-of-band communication supported by the wireless charging transmitting end.

The indication information may indicate the type of supported out-of-band communication in 1 bit, for example: the supported out-of-band communication may be represented by a "1" as bluetooth and a "0" as a near field communication connection; the indication information may also use two bits to indicate the type of supported out-of-band communication, which may be "00" for bluetooth, "01" for near field, and "10" for WiFi connectivity.

When the wireless charging receiving end determines that the wireless charging transmitting end supports out-of-band communication and the type of out-of-band communication adopted by the wireless charging receiving end and the wireless charging transmitting end in current communication is the same, the wireless charging receiving end initiates authentication of wireless charging with the wireless charging transmitting end by adopting first-type communication connection.

When the wireless charging receiving end and the wireless charging transmitting end support a plurality of out-of-band communications simultaneously, the wireless charging receiving end can select one out-of-band communication to perform authentication of wireless charging based on a preset selection rule. For example, the currently connected out-of-band communication may be selected for authentication of wireless charging, or the out-of-band communication with the highest transmission speed may be selected for authentication of wireless charging, or the out-of-band communication with the simplest connection mode may be selected for authentication of wireless charging. In this way, the indication information explicitly indicates the type of out-of-band communication supported by the wireless charging transmitting terminal, and the wireless charging receiving terminal can determine the out-of-band communication for wireless charging authentication according to the type of the out-of-band communication supported by the wireless charging transmitting terminal.

In one embodiment, the wireless charging authentication method may include:

and responding to the fact that the wireless charging transmitting terminal does not support out-of-band communication supported by the wireless charging receiving terminal according to the indication information, and authenticating the wireless charging through the in-band communication.

When the indication information indicates that the wireless charging transmitting terminal does not support the out-of-band communication supported by the wireless charging receiving terminal, the wireless charging receiving terminal cannot perform the authentication of the wireless charging with the wireless charging transmitting terminal through the out-of-band communication. The wireless charging receiving terminal can establish in-band communication with the wireless charging transmitting terminal through the charging coil. Authentication of wireless charging is performed through in-band communication. Therefore, the authentication of wireless charging can be ensured, and the wireless charging is further completed.

In one embodiment, step 202 may comprise: the wireless charging transmitting terminal does not support out-of-band communication of wireless charging; or the wireless charging out-of-band communication supported by the wireless charging transmitting terminal is different from the wireless charging out-of-band communication supported by the wireless charging receiving terminal.

Here, when the wireless charging transmitting terminal does not support out-of-band communication, or the wireless charging out-of-band communication supported by the wireless charging transmitting terminal is different from the wireless charging receiving terminal, the wireless charging receiving terminal may establish in-band communication with the wireless charging transmitting terminal through the charging coil. Authentication of wireless charging is performed through in-band communication. Therefore, the authentication of wireless charging can be ensured, and the wireless charging is further completed.

In one embodiment, step 202 may comprise: and responding to the charging protocol supported by the wireless charging transmitting terminal determined according to the indication information, and authenticating the charging protocol through out-of-band communication.

Here, the indication information sent by the wireless charging transmitting terminal may also carry an indication of a charging protocol supported by the wireless charging transmitting terminal. Here, the charging protocol may include BPP, EPP, and the like. BPP is a wireless charging standard of 5W, EPP is a wireless charging standard up to 15W. The wireless charging receiving terminal determines a charging protocol supported by the wireless charging transmitting terminal according to the indication information, selects an available charging protocol according to the charging protocol supported by the wireless charging receiving terminal, and authenticates the wireless charging according to the available charging protocol.

Illustratively, the indication information indicates that the wireless charging transmitting terminal supports EPP. The wireless charging receiving end supports two wireless charging standards of BFF and EPP. Therefore, the wireless charging receiving terminal can initiate the authentication of the wireless charging based on the EPP.

In one embodiment, step 202 may comprise: in response to the fact that the wireless charging terminal supports the private charging protocol and at least one standard charging protocol according to the indication information, authentication of the private charging protocol is conducted through out-of-band communication;

in response to authentication failure of the private charging protocol, authentication of the standard charging protocol is performed via out-of-band communication.

Here, a proprietary charging agreement is one that a merchant or a combination of merchants make, but is not temporarily recognized by the industry or owner as a standard for charging. A standard charging protocol is a protocol recognized by the industry or owner as a standard for charging. Typically, the proprietary charging protocol may be a wireless charging protocol that is customized by a device vendor to have a different charging efficiency than a standard charging protocol. For example, a proprietary charging protocol may have a higher charging power than a standard charging protocol, which is more efficient in conducting wireless charging. The standard charging protocol may be the Qi standard wireless charging protocol or the like. The proprietary charging protocol may be a different protocol than the standard charging protocol. The proprietary charging protocol may be completely independent of the standard charging protocol. The proprietary charging protocol may be a wireless charging protocol with higher charging efficiency than BPP or EPP.

The indication information can indicate a first charging protocol and a second charging protocol at the same time, and the charging efficiency of the first charging protocol is higher than that of the second charging protocol. The wireless charging receiving end can authenticate the first charging protocol with high charging efficiency in priority and then authenticate the second charging protocol with low charging efficiency. Preferably, the first charging protocol is adopted for wireless charging. The wireless charging receiving end can authenticate the second charging protocol when the wireless charging receiving end does not support the first charging protocol. Here, the first charging protocol may include a private charging protocol, and the second charging protocol may include a standard charging protocol.

The equipment manufacturer can customize wireless charging assemblies of the wireless charging transmitting terminal and the wireless charging receiving terminal, so that the charging power of the wireless charging transmitting terminal and the wireless charging receiving terminal is larger than BPP or EPP, and mutual communication, authentication and the like are performed in a mode different from a standard charging protocol.

When the indication information indicates that the wireless charging terminal supports the private charging protocol and at least one standard charging protocol, if the wireless charging receiving terminal also supports the private charging protocol, the wireless charging can be preferentially performed through the private charging protocol.

When the authentication of the private charging protocol cannot be completed, namely the private charging protocol cannot be adopted for wireless charging, the authentication of the wireless charging of the standard wireless charging protocol can be carried out, and then the standard wireless charging protocol is adopted for charging.

In response to the authentication of the private charging protocol being successful, the authentication of the standard wireless charging is stopped. When the wireless charging transmitting terminal and the wireless charging receiving terminal complete the authentication of the private charging protocol, the authentication of the wireless charging of the standard charging protocol is not performed any more.

Therefore, the private charging protocol with higher charging power can be selected for charging, and the charging efficiency is improved. And the probability of directly selecting the standard charging protocol with lower charging efficiency for wireless charging can be reduced. Here, the authentication of the private charging protocol may be authentication of the private charging protocol or the like.

As shown in fig. 3, the present exemplary embodiment provides a wireless charging authentication method, where the wireless charging authentication method may be applied to a wireless charging transmitting terminal, and the wireless charging authentication method may include:

step 301: sending indication information; the indication information is used for the wireless charging receiving end to determine whether the wireless charging transmitting end supports out-of-band communication;

step 302: and carrying out wireless charging authentication based on out-of-band communication and a wireless charging receiving terminal.

In one embodiment, the indication information is further used for the wireless charging receiving end to determine the type of out-of-band communication supported by the wireless charging transmitting end;

step 302 may include: and responding to the fact that the wireless charging transmitting terminal and the wireless charging receiving terminal both support the same type of out-of-band communication, and performing wireless charging authentication based on the out-of-band communication supported by the line charging transmitting terminal and the wireless charging receiving terminal.

When the wireless charging receiving end and the wireless charging transmitting end support a plurality of out-of-band communications simultaneously, the wireless charging receiving end can select one out-of-band communication to perform authentication of wireless charging based on a preset selection rule. For example, the currently connected out-of-band communication may be selected for authentication of wireless charging, or the out-of-band communication with the highest transmission speed may be selected for authentication of wireless charging, or the out-of-band communication with the simplest connection mode may be selected for authentication of wireless charging.

In this way, the indication information explicitly indicates the type of out-of-band communication supported by the wireless charging transmitting terminal, and the wireless charging receiving terminal can determine the out-of-band communication for wireless charging authentication according to the type of the out-of-band communication supported by the wireless charging transmitting terminal.

In one embodiment, the wireless charging authentication method may include:

and responding to the situation that the wireless charging transmitting terminal does not support the out-of-band communication supported by the wireless charging receiving terminal, and performing authentication of wireless charging through the in-band communication.

In one embodiment, the wireless charging transmitter does not support out-of-band communication supported by the wireless charging receiver, including: the wireless charging transmitting terminal does not support out-of-band communication of wireless charging; or the wireless charging out-of-band communication supported by the wireless charging transmitting terminal is different from the wireless charging out-of-band communication supported by the wireless charging receiving terminal.

In one embodiment, the indication information further comprises: an indication of a charging protocol supported by the wireless charging transmit terminal;

step 302 may include: and authenticating the charging protocol through out-of-band communication and the wireless charging receiving terminal.

Here, the indication information sent by the wireless charging transmitting terminal may also carry an indication of a charging protocol supported by the wireless charging transmitting terminal. Here, the charging protocol may include BPP, EPP, and the like. BPP is a wireless charging standard of 5W, EPP is a wireless charging standard up to 15W.

The wireless charging receiving terminal determines a charging protocol supported by the wireless charging transmitting terminal according to the indication information, selects an available charging protocol according to the charging protocol supported by the wireless charging receiving terminal, and authenticates the wireless charging according to the available charging protocol.

In one embodiment, the indication information further comprises: an indication of a private charging protocol and an indication of at least one standard charging protocol supported by the wireless charging transmitter;

step 302 may include: authentication of a private charging protocol is carried out through out-of-band communication and a wireless charging receiving terminal;

and responding to the authentication failure of the private charging protocol, and authenticating the standard charging protocol with the wireless charging receiving terminal through out-of-band communication.

In response to the authentication of the private charging protocol being successful, the authentication of the standard wireless charging is stopped. When the wireless charging transmitting terminal and the wireless charging receiving terminal complete the authentication of the private charging protocol, the authentication of the wireless charging of the standard charging protocol is not performed any more. Therefore, the protocol with higher charging power can be selected for charging, and the charging efficiency is improved. Here, the authentication of the private charging protocol may be authentication of the private charging protocol or the like.

One specific example is provided below in connection with any of the embodiments described above:

the authentication between the mobile phone with the Low power consumption Bluetooth (BLE) out-of-band communication function and the wireless charger is firstly passed through Bluetooth. The mobile phone acquires first information sent by the wireless charger, wherein the first information is used for indicating whether the wireless charger supports out-of-band communication and the type of the supported out-of-band communication, and the type of the supported out-of-band communication can indicate the types of the two out-of-band communication by using 1 bit. The mobile phone judges whether the wireless charger supports BLE. Here, the mobile phone is a wireless charging receiving terminal (Rx), and the wireless charger is a wireless charging transmitting terminal (Tx).

The mobile phone and the wireless charger can also be authenticated through near field communication.

If the wireless charger supports out-of-band communication, the handset initiates Bluetooth Low Energy (BLE) -based authentication.

If the wireless charger does not support out-of-band communication, the mobile phone initiates authentication of in-band communication.

The first information may also be used for indicating both in-band communication authentication and out-of-band communication authentication, for example, the first information may include both out-of-band communication type and wireless charging protocol, such as EPP type, so that multiple times of information occurrence may be reduced and efficiency may be improved.

It also allows BLE-based proprietary protocols to start before EPP authentication, i.e. proprietary protocol takes precedence; the authentication flows of the private protocol and the standard are relatively independent and do not influence each other.
