The following describes in detail, by means of some embodiments and application scenarios thereof, a discovery method, a device, a UE, and a medium for near field communication provided in the embodiments of the present application with reference to the accompanying drawings.

Technical terms involved in the technical solutions provided in the embodiments of the present application will be described in the following by way of example.

1) Discovery process

LTE near field communication:

in LTE, in order to better support public safety scenario requirements (especially for UEs that are out of network coverage or have poor signal quality under network coverage), near field communication is introduced, and UEs can discover nearby UEs through a discovery mechanism of near field communication, and after discovering nearby UEs, establish through a connection between UEs, and then complete some public safety services, including completing some public safety services through relay UEs.

Since the purpose of LTE introducing near field communication is to meet public security requirements, in the discovery process, the sender of the discovery message does not care or consider the receiver, and the receiver does not care the sender, only needs to discover nearby UEs, and then establish a connection to complete subsequent public security services, including relay communication.

NR near field communication:

NR near field communication is based on LTE near field communication, and further expands to commercial scenes. However, currently, for NR near field communication, including near field communication discovery, the mechanism of LTE is basically used. The sender of the discovery message (the sending UE) and the receiver of the discovery message (the monitoring UE) still do not consider who the peer UE is specifically.

2) Evaluation of discovery procedure

For the above discovery procedure, it is obvious that the commercial scenario of NR near field communication is not satisfied. Such as the user's handset and watch, the discovery and pairing of which is limited to only the handset and the watch, the handset does not actually require other unrelated watches to be paired with and connected to. If the discovery mechanism of LTE is still in use, the handset may receive pairing and connection requests from other watches around, resulting in unnecessary resource waste. Since the existing short-range discovery mechanism and relay discovery mechanism are used to fulfill public security scene requirements, discovery and identification of specific users in a business scene are not considered, so that the following situations can be caused when the discovery mechanism is continuously executed in the business scene: the discovery purpose of a specific user is not achieved; the purpose that the sending end and the specific receiving end establish subsequent direct communication or relay communication is not achieved; the sender receives discovery replies or connection establishment requests of a plurality of irrelevant destination users.

In summary, the near field communication needs to further consider the business scenario, and the sending end and the receiving end are not limited by public security, and because the sending end may only need to discover a specific receiving end, or the receiving end only needs to discover a specific sending end, the discovery process of the near field communication needs to carry an explicit receiving end and sending end, so that the UE can determine whether to respond to the discovery of the end UE or establish a connection with the opposite end UE.

In order to solve the above-described problem, in the embodiment of the present application, the first UE may transmit a close range communication discovery message; wherein the near field communication discovery message includes at least one of: first user information of a first UE; and second user information of at least one second UE, wherein the second UE is the UE which the first UE wants to discover. According to the method, the short-range communication discovery message sent by the first UE comprises the user information of the first UE and/or the user information of at least one second UE which the first UE wants to discover, so that the first UE can conveniently discover the specific second UE, and the waste of wireless resources in the discovery process of the short-range communication can be reduced.

An embodiment of the application provides a method for discovering near field communication, and fig. 2 shows a flowchart of the method for discovering near field communication provided in the embodiment of the application. As shown in fig. 2, the discovery method of near field communication provided in the embodiment of the present application may include the following step 201.

Step 201, the first UE transmits a near field communication discovery message.

In the embodiment of the present application, the above near field communication discovery message may include at least one of the following: first user information of the first UE, second user information of the at least one second UE.

In this embodiment of the present application, the second UE is a UE that the first UE wants to discover.

It will be appreciated that the at least one second UE establishes close range communication with each of the at least one second UE for UEs that the first UE wants to discover, i.e., the first UE needs to establish close range communication with each of the at least one second UE.

In this embodiment of the present application, each of the at least one second UE corresponds to one piece of second user information.

Optionally, in an embodiment of the present application, the first user information may be used to identify at least one of the first UE and a user of the first UE; the second user information may be used to identify at least one of the second UE and a user of the second UE.

Optionally, in the embodiment of the present application, the user information of the UE may include UE application ID (user equipment application identifier).

It is understood that the first user information may include a first UE application ID and the second user information may include a second UE application ID, the user information being different for each UE.

In the embodiment of the application, since the user information of the UE may identify the UE and/or the user of the UE, the UE and/or the user of the UE may be known through the user information.

Alternatively, in the embodiment of the present application, the first user information and/or the second user information may be provided by an application layer, or may be preconfigured.

It will be appreciated that a UE may be provided by the application layer or preconfigured with user information that may uniquely identify the UE and/or the user of the UE.

Alternatively, in the embodiment of the present application, the first UE may send the close range communication message through broadcasting.

In the method for discovering near field communication provided in the embodiment of the present application, since the near field communication discovery message sent by the first UE includes the user information of the first UE and/or the user information of at least one second UE that the first UE wants to discover, the first UE can discover a specific second UE conveniently, so that waste of UE resources in the discovery process of near field communication can be reduced.

Optionally, in the embodiment of the present application, after the step 201, the method for discovering near field communications provided in the embodiment of the present application may further include the following steps 202 and 203.

Step 202, the first UE receives a close range communication establishment request message sent by the first target UE.

Alternatively, in the embodiment of the present application, after receiving the above-mentioned close range communication discovery message, the first target UE may send the above-mentioned close range communication establishment request message to the first UE.

Alternatively, in the embodiment of the present application, the above-mentioned close range communication establishment request message may be used to request the first UE to establish close range communication.

Step 203, the first UE establishes close range communication between the first UE and the first target UE based on the close range communication establishment request message.

Optionally, in an embodiment of the present application, the above-mentioned close range communication establishment request message may include at least one of the following: the method comprises the steps of first user information and user information of a first target UE.

Alternatively, in the embodiment of the present application, the first target UE may be one or more UEs of the at least one second UE.

It can be understood that, because the first target UE is the UE that the first UE wants to discover, after receiving the above-mentioned close range communication establishment request message sent by the first target UE, the first UE may establish close range communication with the first target UE to complete the required service.

In this embodiment of the present application, after receiving the close range communication establishment request message sent by one or more UEs (i.e., the first target UE) in the at least one second UE, the first UE may establish close range communication with the first target UE based on the close range communication establishment request message including the first user information and/or the user information of the first target UE, so that accuracy of establishing close range communication between specific UEs may be improved.

Optionally, in the embodiment of the present application, before the step 202, the method for discovering near field communications provided in the embodiment of the present application may further include a step 204 described below.

Step 204, the first UE receives the reply message sent by the second target UE.

In the embodiment of the present application, the reply message may be used to return the short-range communication discovery message.

Alternatively, in the embodiment of the present application, the second target UE may be one or more UEs of the first target UE.

Optionally, in an embodiment of the present application, the reply message may include at least one of the following: first user information and user information of a second target UE.

In this embodiment of the present application, the second target UE may enable the first UE to learn the second target UE and/or the user of the second target UE by sending the reply message to the first UE, and then request the first UE to establish the close range communication by sending the close range communication establishment request message to the first UE.

In this embodiment of the present application, since the first UE may receive the reply message sent by one or more UEs (i.e., the second target UE) in the first target UE, and the reply message may include the first user information and/or the user information of the second target UE, the first UE may quickly and accurately discover the second target UE, so that discovery efficiency of near-field communication may be improved, so as to further reduce radio resource waste in a discovery process of near-field communication.

An embodiment of the present application provides a method for discovering near field communication, and fig. 3 shows a flowchart of the method for discovering near field communication provided in the embodiment of the present application. As shown in fig. 3, the discovery method of near field communication provided in the embodiment of the present application may include the following steps 301 and 302.

Step 301, the third UE receives a near field communication discovery message from the first UE.

Step 302, in a case where the close range communication discovery message satisfies the first condition, the third UE sends the first message to the first UE.

Optionally, in an embodiment of the present application, the first message may include at least one of first user information of the first UE and user information of the third UE.

Optionally, in an embodiment of the present application, the above near field communication discovery message may include at least one of the following: first user information, second user information of at least one second UE.

Optionally, in the embodiment of the present application, the second UE is a UE that the first UE wants to discover.

For other descriptions in the embodiments of the present application, reference may be made specifically to the descriptions related to the foregoing embodiments, and in order to avoid repetition, details are not repeated herein.

Optionally, in an embodiment of the present application, the foregoing meeting the first condition by the close range communication discovery message may include at least one of: the near field communication discovery message comprises first user information, and the first UE is a UE (1) monitored by a third UE; the near field communication discovery message includes at least one second user information, and the user information of the third UE is matched with the at least one second user information (2).

Alternatively, in the embodiment of the present application, in the above (1), the UE monitored by the third UE may be a UE that has established close range communication with the third UE.

Optionally, in the embodiment of the present application, in (2) above, the matching between the user information of the third UE and the at least one second user information may be that the matching degree between the user information of the third UE and the at least one second user information is greater than or equal to a preset threshold.

It may be understood that in the above (2), the third UE may be a UE of the above at least one second UE, or may be a UE other than the at least one second UE, and the user information matches with the at least one second user information.

In the embodiment of the present application, in a case where the above-mentioned close range communication discovery message satisfies the first condition and includes (1) and/or (2) above, the third UE may send the first message to the first UE.

In the embodiment of the present application, the first UE may send the first message to the first UE when the short-range communication discovery message includes the first user information and the first UE is the UE monitored by the third UE, and/or when the short-range communication discovery message includes at least one second user information and the user information of the third UE is matched with the at least one second user information, so that flexibility of the UE for discovering the specific UE may be improved.

Alternatively, in the embodiment of the present application, the first message may be used to request to establish close range communication (one possible implementation), or used to return the above close range communication discovery message (another possible implementation).

Possible implementation manner

Alternatively, in the embodiment of the present application, the first message may include a first close range communication establishment request message.

For a specific description of the close range communication establishment request message, reference may be made to the related description in the above embodiment, and in order to avoid repetition, a description thereof will be omitted.

It may be appreciated that after the third UE sends the first close range communication establishment request message to the first UE, the first UE may receive the first close range communication establishment request message and establish close range communication between the first UE and the third UE based on the received first close range communication establishment request message.

The following exemplarily describes a discovery method of near field communication provided in the embodiments of the present application with reference to the accompanying drawings.

For example, as shown in fig. 4, when S401, UE1 (i.e., the first UE) needs to discover a specific UE, the UE1 may send (broadcast) a near field communication discovery message. S402, if the close range communication discovery message includes the user information (i.e., the first user information) of the UE1 and the UE1 is the UE that the UE4 (i.e., the third UE) listens to, and/or includes the user information of the UE0 (i.e., at least one second UE) and the user information of the UE4 matches with the user information (i.e., the second user information) of the UE0, the UE4 may send a close range communication establishment request message (i.e., the first close range communication establishment request message) to the UE1 after receiving the close range communication discovery message from the UE 1. And, the close range communication establishment request message may include user information of the UE1 and/or user information of the UE4, so that the UE1 may establish close range communication with the UE4 based on the close range communication establishment request message after receiving the close range communication establishment request message. It can be seen that, since the UE1 is not a UE monitored by the UE2, the UE3 and the UE5, and the user information of the UE2, the UE3 and the UE5 is not matched with the user information of the UE0, the UE2, the UE3 and the UE5 will not send the close range communication establishment request message to the UE1, so that the discovery of the UE1 on the specific UE can be achieved, and the waste of UE resources in the discovery process of the close range communication can be reduced.

In the embodiment of the present application, since the first message may include a first close range communication establishment request message, and the first close range communication establishment request message may include the first user information and/or the user information of the third UE, accuracy of establishing close range communication between specific UEs may be improved.

Another possible implementation

Optionally, in the embodiment of the present application, the first message may include a reply message, where the reply message is used to reply to the above-mentioned close range communication discovery message, and after step 302, the method for discovery of close range communication provided in the embodiment of the present application may further include step 303 described below.

Step 303, the third UE sends a second close range communication establishment request message to the first UE.

Optionally, in the embodiment of the present application, after replying to the above-mentioned close range communication discovery message, the third UE may send a second close range communication establishment request message to the first UE to request to establish close range communication.

It may be appreciated that after the third UE sends the reply message to the first UE, the first UE may receive the reply message and learn the third UE and/or the user of the third UE through the reply message; and then the third UE may send a second close range communication establishment request message to the first UE, so that after the first UE receives the second close range communication establishment request message, close range communication between the first UE and the third UE may be established based on the second close range communication establishment request message.

For example, as shown in fig. 5, when a specific UE needs to be found by S501, UE1 (i.e., the first UE), the UE1 may send (broadcast) a near field communication discovery message. S502, if the close range communication discovery message includes the user information (i.e., the first user information) of the UE1 and the UE1 is the UE that the UE4 (i.e., the third UE) listens to, and/or includes the user information of the UE0 (i.e., at least one second UE) and the user information of the UE4 matches with the user information (i.e., the second user information) of the UE0, the UE4 may send a reply message to the UE1 after receiving the close range communication discovery message from the UE 1. And, the reply message may include the user information of the UE1 and/or the user information of the UE4, so that the UE1 may learn the UE4 and/or the user of the UE4 through the reply message after receiving the reply message. It can be seen that, since the UE1 is not the UE monitored by the UE2, the UE3 and the UE5, and the user information of the UE2, the UE3 and the UE5 is not matched with the user information of the UE0, the UE2, the UE3 and the UE5 will not send a reply message to the UE1, so that the UE1 can conveniently and rapidly discover the specific UE, and the discovery efficiency of the near field communication can be improved.

Further, after sending the reply message to the UE1, the UE4 may send a close range communication request message (i.e. a second close range communication request message) to the UE1 to request the UE1 to establish close range communication, so that after receiving the close range communication establishment request message, the UE1 may establish close range communication with the UE4 based on the close range communication establishment request message.

In the embodiment of the present invention, since the first message may include a reply message for replying to the close range communication discovery message, and the third UE may further send a second close range communication establishment request message to the first UE after sending the first message to the first UE, so as to request the first UE to establish close range communication, the first UE may conveniently and rapidly discover the specific UE, and thus, rapid and accurate establishment of close range communication between the specific UEs may be achieved.

Optionally, in the embodiment of the present application, the UE may determine to send the close range communication request to the first UE through one possible implementation manner or another possible implementation manner according to different time periods in a day, or a service type that needs to be completed, or the like.

Optionally, in the embodiment of the present application, the foregoing procedure for establishing near field communication may be applicable to a relay communication scenario, and for a specific description of the procedure for establishing near field communication in the relay communication scenario, reference may be made to the related description in the foregoing embodiment, so that, for avoiding repetition, a description is omitted here.
