As shown in fig. 2, a flowchart of a method 200 for near field communication according to an exemplary embodiment of the present application is provided, where the method 200 may be, but is not limited to, executed by a first terminal, and in particular may be executed by hardware and/or software installed in the first terminal. In this embodiment, the method 200 may at least include the following steps.

S210, the first terminal performs a direct discovery process on the PC5 interface based on the preconfigured target configuration information.

In this embodiment, there may be various pre-configuration manners of the target configuration information, for example, when the first terminal is in a radio resource control (Radio Resource Control, RRC) active state or a connected state, the network side pre-configures the target configuration information to the first terminal through RRC signaling or the like, and for example, pre-configures the target configuration information to the first terminal in a protocol contract or the like; for example, the target configuration information may be preconfigured in the first terminal by default when the first terminal leaves the factory, which is not limited herein. It should be noted that, the preconfiguration manner of the target configuration information is different from the network side configuration manner in that the first terminal may update the target configuration information according to the requirement of the first terminal or the indication of the network side, but the first terminal may not update the preconfigured target configuration information while updating the target configuration information.

Optionally, the target configuration information at least includes configuration information related to a direct discovery process on the PC5 interface, such as ProSe related discovery parameters, an execution policy of the direct discovery process on the PC5 interface, and the like, where specific content of the target configuration information may be configured according to a communication requirement, and is not limited herein.

Optionally, before S210, the method may further include:

s200, the first terminal acquires preconfigured target configuration information.

In this embodiment, the first terminal performs the direct discovery process on the PC5 interface based on the preconfigured target configuration information, and on one hand, for some scenes where the relevant discovery parameters of ProSe are not available or cannot be obtained, the direct discovery process on the PC5 interface can also be performed, so as to ensure the performance of the communication network.

As shown in fig. 3, a flowchart of a method 300 for near field communication according to an exemplary embodiment of the present application is provided, where the method 300 may be, but is not limited to, executed by a first terminal, and in particular may be executed by hardware and/or software installed in the first terminal. In this embodiment, the method 300 may at least include the following steps.

S310, the first terminal performs a direct discovery process on the PC5 interface based on the preconfigured target configuration information.

It may be appreciated that, in addition to the related description in the method embodiment 200, as a possible implementation manner, if the first terminal cannot obtain valid relevant discovery parameters of ProSe (such as ProSe application Code (ProSe Application Code), proSe restriction Code (ProSe Restricted Code), proSe Query Code (ProSe Query Code), proSe response Code (ProSe Response Code), etc.), the first terminal may perform the direct discovery procedure on the PC5 interface based on the preconfigured target configuration information, then please refer to fig. 3 again, and the first terminal performing the direct discovery procedure on the PC5 interface based on the preconfigured target configuration information may include S311, as follows.

S311, in case the first event is satisfied, the first terminal performs a direct discovery process on the PC5 interface based on the preconfigured target configuration information.

Wherein the first event may include at least any one of the following (11) - (12).

(11) The first terminal is not connected with the network side.

Optionally, the case where the first terminal is not connected to the network side may include at least one of the following (111) - (114).

(111) The first terminal has no network coverage, which may also be referred to as the first terminal having no RAN coverage.

(112) The first terminal does not have non-access stratum (Non Access Stratum, NAS) capability, i.e. the first terminal cannot connect with the network side.

(113) The first terminal registers the first network but does not register the second network successfully in the process of registering with the second network. Among them, it can be understood that: the first terminal registers the first network, and then the first terminal deletes the relevant discovery parameter of ProSe configured by the first network, or the first terminal does not have a use authority of using the relevant discovery parameter of ProSe configured by the first network, which results in the first terminal not having a valid relevant discovery parameter of ProSe configured by a network side.

(114) The first terminal sends a seventh discovery request to a network side, but does not receive a response message of the network side. Wherein the seventh discovery request is used for requesting ProSe related discovery parameters from the network side. For example, in the process from network coverage to no network coverage, the first terminal sends a seventh discovery request in the network coverage area, but moves to the no network coverage area without receiving a response message sent by the network side.

(12) The relevant discovery parameters of the ProSe configured by the network side in the first terminal are invalid and cannot be updated. For example, the first terminal leaves the area served by the network side, or the relevant discovery parameters of ProSe configured by the network side exceed a predetermined validity time, etc.

In this case, as an implementation manner, an implementation manner in which the first terminal performs the direct discovery process on the PC5 interface based on the preconfigured target configuration information may be different according to the target configuration information, and a description of the implementation process will be provided below with reference to examples 1 to 3, respectively.

Example 1

Assuming that the target configuration information includes relevant discovery parameters of the ProSe, the relevant discovery parameters of the ProSe include at least one of the following (21) - (24).

(21) A first discovery code comprising a first subcode and/or a second subcode, the first subcode being used for a first direct discovery process; wherein the first direct discovery process is a direct discovery process based on a first model over a PC5 interface.

Optionally, the first subcode includes at least one of ProSe restriction code, proSe application code. .

In one implementation, the ProSe restriction code is usable for a restricted direct discovery process (restricted direct discovery) based on a first model on a PC5 interface, and the ProSe application code is usable for a published direct discovery process (open direct discovery) based on the first model on the PC5 interface.

For example, assuming that the first terminal needs to perform a first direct discovery procedure, and the first direct discovery procedure is a restricted direct discovery procedure, the first terminal may send a first discovery request to the second terminal, where the first discovery request carries the ProSe restriction code.

For another example, assuming that the first terminal needs to perform a first direct discovery procedure, and the first direct discovery procedure is a published direct discovery procedure, the first communication device may send a first discovery request to the second terminal, where the first discovery request carries the ProSe application code.

In this embodiment, the ProSe application code may associate a PLMN ID with a default application layer ID (default Application layer user identity).

The second subcode is used for a second direct discovery process, wherein the second direct discovery process is a direct discovery process based on a second model over a PC5 interface. Optionally, the second subcode may include at least one of ProSe query code and ProSe response code.

For example, assuming that the first terminal needs to perform the second direct discovery process, the first communication device may send a first discovery request to the second terminal, where the first discovery request carries the ProSe query code, and correspondingly, after receiving the first discovery request, the second terminal determines that the first terminal can discover the ProSe query code, and if the first terminal determines that the first terminal can discover the ProSe query code, the first terminal sends a response message to the first terminal, where the response message may carry the ProSe response code.

It is noted that the first model referred to in the present application may also be referred to as model A (model A), and the second model may also be referred to as model B (model B). Wherein the model A uses a single discovery protocol message (i.e., request), such as a direct discovery procedure based on model A, a first terminal needs to send a discovery request, but a second terminal that receives the discovery request does not need to feed back a response message; while the model B uses two discovery protocol messages (i.e., a request and a response), such as a direct discovery process based on the model B, a first terminal needs to send a discovery request and a second terminal receiving the discovery request needs to feed back a response message.

(22) First filtering information comprising a first Filter, which may also be referred to as Discovery Filter (Discovery Filter), for matching the first subcode and for a first direct Discovery process, i.e. a model a based PC5 direct Discovery process (5G ProSe direct Discovery procedure over PC5 with model A). Optionally, the first filter may include at least one of the following (221) - (223).

(221) ProSe application code; the ProSe application code is used for matching with the ProSe application code in the first subcode. For example, when the first terminal receives a second discovery request sent by a second terminal, if the first terminal determines that the ProSe application code in the first filter is matched with the ProSe application code carried in the second discovery request, the first terminal determines that the first terminal can be discovered by the second terminal, otherwise, determines that the first terminal cannot be discovered by the second terminal.

(222) ProSe restriction codes; the ProSe restriction code is used for matching with the ProSe restriction code in the first subcode. For example, when the first terminal receives a second discovery request sent by a second terminal, if the first terminal determines that the ProSe restriction code in the first filter is matched with the ProSe restriction code carried in the second discovery request, the first terminal determines that the first terminal can be discovered by the second terminal, otherwise, the first terminal cannot be discovered by the second terminal.

(223) ProSe application mask (ProSe Application Mask code). The ProSe application code is used for matching with a ProSe application code or a ProSe restriction code in the first subcode. For example, when the first terminal receives a second discovery request sent by a second terminal, if the first terminal determines that a ProSe application mask matches a ProSe application code or a ProSe restriction code carried in the second discovery request, the first terminal determines that the first terminal can be discovered by the second terminal, otherwise, the first terminal cannot be discovered by the second terminal. In one implementation, at least a portion of the ProSe application code information may be included in the ProSe application mask.

The second filter may also be referred to as a discovery query filter (Discovery Query Filter) or a discovery response filter (Discovery Response Filter) for matching the second subcode and for a second direct discovery process, i.e. the second filter is for a model B based PC5 direct discovery process (5G ProSe direct discovery procedure over PC5 with model B).

Optionally, the second filter includes at least one of ProSe query codes, proSe query codes.

The ProSe query code is used for matching with a ProSe query code in a second subcode, for example, when the first terminal receives a second discovery request sent by a second terminal, if the first terminal determines that the ProSe query code in the second filter matches with a ProSe query code carried in the second discovery request, the first terminal determines that the first terminal can be discovered by the second terminal, and sends a response message to the second terminal, where a ProSe response code can be carried in the response message, otherwise, the first terminal determines that the first terminal cannot be discovered by the second terminal.

(23) A second discovery code, the second discovery code being common to the first direct discovery process and the second direct discovery process; that is, whether the first terminal performs a first direct discovery process or a second direct discovery process may be performed based on the second discovery code.

Optionally, the second discovery code is associated with a terminal identifier (UE ID) on the application layer, so that when the second terminal receives the first discovery request sent by the first terminal, the second terminal can determine whether the second terminal discovers according to the UE ID on the application layer associated with the second discovery code in the first discovery request, if the second terminal discovers the second terminal, the second terminal can determine that the second terminal discovers the second terminal, if the second terminal discovers the second terminal does not discover the second terminal.

In one implementation, the second discovery code includes an Application identification (Application ID) and a PLMN identification. The Application identifier may be a ProSe identifier or an Application ID, and the PLMN may be a PLMN where the first terminal is located, and/or a PLMN where a 5G direct discovery name management function (direct discovery name management function, DDNMF) is located, which is not limited herein.

(24) And second filtering information, wherein the second filtering information is used for matching the second discovery code, and the second filtering information is commonly used for a first direct discovery process and a second direct discovery process.

For example, assuming that the first terminal receives a second discovery request sent by the second terminal, the first terminal matches the second filtering information with a second discovery code in the second discovery request, if the second filtering information and the second discovery code match, the first terminal determines that the second filtering information can be discovered by the second terminal, and determines whether to feed back a response message to the second terminal according to a first model or a second model corresponding to the second discovery request; otherwise, if the two do not match, the first terminal may determine that it cannot be found by the second terminal.

It should be noted that, for the foregoing first discovery code, first filtering information, second discovery code, and second filtering information, if the first terminal is used as an initiator of the direct discovery process on the PC5 interface, the first terminal may perform the sending of the first discovery request based on the first discovery code or the second discovery code; if the first terminal is to be discovered as a direct discovery process on the PC5 interface, the first terminal may match the first filter information or the second filter information with a discovery code in the received second discovery request to determine whether to be discovered.

In addition, for the aforementioned second terminal, similar to the first terminal, the target configuration information is preconfigured on the second terminal, or the target configuration information on the second terminal may also be obtained through interaction with the network side, so as to be used for initiating the second discovery request and responding to the first discovery request, which is not limited herein.

Of course, for the aforementioned target configuration information, the target configuration information may be preconfigured in a universal integrated circuit card (Universal Integrated Circuit Card, UICC) in the first terminal; the target configuration information may also be preconfigured in the Mobile Equipment (ME) in the first terminal, which is not limited herein.

In this example 1, by pre-configuring the relevant discovery parameters of ProSe for the first terminal, when the relevant discovery parameters of ProSe that are not connected to or configured by the network side of the first terminal fail, the direct discovery process on the PC5 interface can also be executed, so as to ensure the communication performance.

Example 2

Assuming that the target configuration information includes a first identity, the first terminal may perform a direct discovery procedure on the PC5 interface based on the first identity. Optionally, the first identity includes a ProSe identifier and/or an Application identity (Application ID).

Based on this, in one implementation, when the first terminal is acting as an initiator of the direct discovery procedure, the first terminal may send a fifth discovery request, where the fifth discovery request includes the first identifier.

In another implementation, when the first terminal is a discoveree of the direct discovery process, the first terminal may determine whether to be discovered by the second terminal according to a first identifier included in a sixth discovery request when the first terminal receives the sixth discovery request. For example, the first terminal matches the first identifier with the first identifier carried in the sixth discovery request, if the first identifier and the first identifier match, the first terminal determines that the first identifier is discovered by the second terminal, otherwise, the first terminal determines that the first identifier is not discovered by the second terminal.

It should be noted that the first terminal performs the direct discovery process on the PC5 interface based on the first identifier, which may be a direct discovery process based on the first model or a direct discovery process based on the second model, which is not limited herein.

In this example 2, through the pre-configuration of the first identifier, when the first terminal is not connected to the network side or the relevant discovery parameter of ProSe configured by the network side fails, a direct discovery process on the PC5 interface can be executed based on the first identifier, so as to ensure communication performance.

Example 3

Assuming that the target configuration information is execution policy information of a direct discovery process on a PC5 interface when the first terminal satisfies a first event, that is, the first terminal cannot acquire the relevant discovery parameter of ProSe without configuring the relevant discovery parameter of ProSe in the target configuration information, in this case, the first terminal may execute the first direct discovery process or execute the second direct discovery process when executing the direct discovery process on the PC5 interface based on the preconfigured target configuration information.

Wherein the first direct discovery process is a direct discovery process performed on a PC5 interface based on a first model, and the first direct discovery process is a public direct discovery process, and a ProSe application code in a third discovery request in the first direct discovery process is in a default (absent) state; the second direct discovery process is a direct discovery process based on a second model on the PC5 interface, and ProSe query codes in a fourth discovery request in the second direct discovery process are in a default state.

That is, the first terminal may perform a public direct discovery process (e.g., model A open discovery) based on the first model on the PC5 interface or a direct discovery process based on the second model on the PC5 interface without any one of ProSe restricted code, proSe query code, proSe Response Code, although the network side does not allow the first terminal to perform a limited direct discovery process (e.g., model A restricted discovery) based on the first model on the PC5 interface, it is noted that the ProSe application code is not carried in the third discovery request in the first direct discovery process, and the ProSe query code is not carried in the fourth discovery request in the second direct discovery process.

In this example 3, by pre-configuring the execution policy of the direct discovery process of the first terminal when the relevant discovery parameter does not have ProSe, the first terminal can smoothly execute the direct discovery process on the PC5 interface based on the target configuration information when the relevant discovery parameter does not have ProSe, thereby ensuring communication performance.

Examples 1-3 given above, the first terminal is based on which of examples 1-3 performs the direct discovery process on the PC5 interface, and may be implemented by protocol conventions, higher layer configurations, etc., without limitation.
