In some embodiments, a communication method is provided for application to a first functional entity. The first functional entity may in particular be a PCF, a first UE, a DDNMF or an application function AF (Application Function).

Fig. 1 is a flow chart of a communication method provided in an embodiment of the present application, as shown in fig. 1, the method mainly includes the following steps:

s101: and acquiring the proximity service communication analysis information of the first User Equipment (UE).

In this step, the proximity service communication analysis information includes statistical information and/or predictive information related to the proximity service communication of the first UE.

Specifically, the PCF, the first UE, the DDNMF, or the AF may acquire the proximity service communication analysis information of the first UE from a second functional entity, which may be NWDAF, and the second functional entity may generate the proximity service communication analysis information after analyzing the proximity service communication of the first UE.

S102: based on the proximity service communication analysis information, one of the following is performed: determining a proximity service communication policy; or determining at least one target UE, and carrying out proximity service communication with the at least one target UE.

In this step, the proximity services communication policy is used to direct the first UE to conduct proximity services communication with at least one target UE.

Specifically, if the first functional entity is PCF or AF, after acquiring the proximity service communication analysis information, the proximity service communication policy of the first UE may be determined according to the proximity service communication analysis information, and the proximity service communication policy is sent to the first UE, so that the first UE determines at least one target UE to perform proximity service communication according to the proximity service communication policy.

Optionally, if the first functional entity is the AF, the AF may further determine a proximity service communication parameter (or a set of proximity service communication parameters) for a specific application after receiving the proximity service communication analysis information, and send the proximity service communication parameter to the PCF, so that the PCF determines a proximity service communication policy according to the proximity service communication parameter (in this case, the proximity service communication policy includes the proximity service communication parameter), and sends the proximity service communication policy to the first UE or the DDNMF. Wherein the AF may send the proximity service communication parameters (or set of proximity service communication parameters) to the network capability opening function NEF (Network Exposure Function) and/or the unified database UDR (Unified Data Repository), the NEF and/or the UDR in turn send the proximity service communication parameters (or set of proximity service communication parameters) to the PCF.

Optionally, the AF may also directly send the proximity service communication parameters (or the set of proximity service communication parameters) to the first UE or the DDNMF, so that the first UE or the DDNMF directly determines at least one target UE according to the proximity service communication parameters. Wherein the AF may send the proximity service communication parameter (or set of proximity service communication parameters) to the NEF, which in turn sends the proximity service communication parameter (or set of proximity service communication parameters) to the DDNMF.

Specifically, if the first functional entity is the first UE, after the first UE acquires the proximity service communication analysis information, the first UE may directly select at least one target UE for direct communication according to the proximity service communication analysis information, or select at least one target UE as a relay, and then perform proximity service communication with the at least one target UE.

Optionally, when the first UE selects at least one target UE for direct communication, at least one target UE meeting the following conditions may be selected from a plurality of neighbor UEs supporting a specific neighbor service for neighbor service communication:

1) Optimal communication performance (e.g., support high QoS or QoE, and/or support high data transmission rates); and/or the number of the groups of groups,

2) The percentage of available resources is highest.

Alternatively, when the first UE selects at least one target UE as a relay, the first UE may select at least one target UE satisfying the following condition as a relay UE among a plurality of neighbor UEs supporting a specific relay mode neighbor service:

1) Relay performance is optimal (e.g., support relay mode proximity services high QoS or QoE requirements, and/or support high relay transmission rates); and/or the number of the groups of groups,

2) The percentage of available resources is highest; and/or the number of the groups of groups,

3) With good mobility performance (e.g., long time in 3GPP network, low frequency of moving out of 3GPP network, and/or high handover success rate).

Specifically, if the first functional entity is a DDNMF, after acquiring the proximity service communication analysis information, the DDNMF may directly determine information of at least one target UE, and send the information of the at least one target UE to the first UE, so that the first UE performs proximity service communication with the at least one target UE.

According to the communication method provided by the embodiment of the application, the second functional entity analyzes the adjacent service communication of the first UE, after the adjacent service communication analysis information is generated, the first functional entity obtains the adjacent service communication analysis information, so that an adjacent service communication strategy for guiding the first UE to conduct adjacent service communication with at least one target UE can be determined, or at least one target UE is directly determined, and the first UE and the at least one target UE can be enabled to successfully establish adjacent service communication.

Specifically, the identification information of the proximity service, or the identification information of the relay mode proximity service, may enable the first UE to determine whether to directly communicate or communicate through the relay. The second functional entity analyzes the proximity service communication of the first UE, specifically may analyze performance information and status information of the first UE and its proximity UE, so as to select an optimal target UE for the first UE, so that a success rate of the proximity service communication between the first UE and the target UE may be greatly improved.

In particular, the statistical information of the first UE and/or the at least one target UE may include first statistical information and second statistical information, and the prediction information may include first prediction information and second prediction information. The specific examples are shown in the following table:

table 1 statistics table of first UE and/or at least one target UE

/>

Table 2 prediction information table of first UE and/or at least one target UE

Specifically, when the first functional entity obtains the proximity service communication analysis information, the first functional entity may first send a proximity service communication analysis request to the second functional entity, and after receiving the proximity service communication analysis request, the second functional entity analyzes the proximity service communication of the first UE, thereby generating the proximity service communication analysis information, and sends the proximity service communication analysis information to the first functional entity, so as to analyze the proximity service communication of the first UE through the second functional entity, thereby realizing improvement of the success rate of the proximity service communication between the first UE and at least one target UE.

Alternatively, the proximity service communication analysis request may request the proximity service communication analysis information once or subscribe to the proximity service communication analysis information a plurality of times (for example, request the second functional entity NWDAF to transmit the proximity service communication analysis information at a certain period or retransmit the proximity service communication analysis information when the proximity service communication analysis information is updated).

Optionally, if the first functional entity is the first UE, the first UE may send the proximity service communication analysis request to the NWDAF by one of the following ways:

1) The first UE sends a data packet containing the proximity service communication analysis request to a user plane function UPF through a user plane, and the UPF forwards the analyzed analysis request to an NWDAF;

2) The first UE sends a proximity service communication analysis request to a core network control function (e.g. an access and mobility management function AMF or a session management function SMF) through control plane signaling, and the core network control function entity forwards the proximity service communication analysis request to the NWDAF.

Specifically, the proximity service communication analysis request may include proximity service communication description information for indicating to the NWDAF that proximity service communication-related analysis information of the first UE is requested, for example, the following parameters:

The proximity traffic communication analysis request may include analysis target information (Target of Analytics Reporting): for indicating which UE/UEs are to be AI-related analyzed. For example:

target of Analytics Reporting = UE1 ID (identity of UE1, indicating analysis of UE 1), where UE1 may be the first UE;

target of Analytics Reporting = UE2 ID (identity of UE2, meaning analysis of UE 2), where UE2 is a target UE that may be in proximity traffic communication with UE1, or a target UE that is a Relay (i.e. Relay UE), or other target UE of interest to UE 1. UE1 may discover UE2, which may perform proximity service communication with UE1 or act as a relay UE, through a Direct Discovery (Direct Discovery) procedure;

Target of Analytics Reporting = list of UE IDs (list of UE identities, indicating analysis of multiple UEs identified), where the UEs in the list are target UEs that can communicate short range with UE1, or target UEs that are relays, or other target UEs of interest to UE 1. UE1 may discover these UEs that may communicate with the UE for proximity services or as relay UEs through a Direct Discovery (Direct Discovery) procedure;

target of Analytics Reporting = UE Group ID (UE Group identity, indicating analysis of a Group of UEs), which may be the Group in which UE1 is located, or a target UE Group (e.g. 1-to-many communication, chat, conference, etc.) communicating with UE1, or other target UE Group of interest to UE 1;

The proximity services communication analysis request may include other information such as: time period information indicating that proximity service communication analysis information in a past or future period is requested.

Optionally, if the first functional entity is AF, the proximity service communication analysis request may further include: the Application ID of the Application of interest for AF, for example, set Application id=prose identifier_1 or rsc_1, represents proximity service communication analysis information of the Application of interest (Application). Further, the AF may set analysis target information Target of Analytics Reporting, target of Analytics Reporting =one or more UE identities supporting the above specific application, or UE group identities, or all UEs (note that other conditions in analysis filtering information need to be satisfied at the same time) according to the information of the UE supporting the above specific application.

The PCF may set these parameters based on information locally configured or stored by the PCF. Alternatively, the PCF may send a request to the DDNMF or the unified data management function UDM (Unified Data Management), where the request carries the identities (UE IDs) of one or more UEs, and then set the corresponding parameters in the proximity service communication analysis request according to ProSe identifier or RSC carried in a response message from the DDNMF or the UDM (e.g., set Application id=prose identifier_1 or rsc_1).

Specifically, after receiving the proximity service communication policy, the first UE may use proximity service communication with at least one target UE according to indication information for indicating that proximity service communication is used in the proximity service communication policy, or use relay communication with at least one target UE according to indication information for indicating that proximity service communication is used in a relay mode; the information of the at least one target UE may include: the target UE is within a proximity service communication range of the first UE (e.g., within an area with a radius of 100 meters centered on the first UE), the target UE supports QoS or QoE requirements for a particular proximity service, the target UE has available resources (e.g., 45% of the resources of the target UE are available); the information of the target application of the proximity service communication may include: application identification information of a target application, packet filtering information (such as an IP triplet or a quintuple), identification information of a proximity service, identification information of a relay mode proximity service, and the like; the time of the proximity service communication (i.e., the time of validity of the proximity service communication), the area (and/or location) of the proximity service communication, the quality of service QoS parameter of the proximity service communication may enable the first UE to conduct the proximity service communication at a particular time, in a particular area (and/or location), for a particular service (or application), and/or using a particular QoS parameter.

Alternatively, if there is a target UE that satisfies one or more conditions in the proximity service communication policy, then the proximity service communication may be set for a particular service in the proximity service communication policy, otherwise the proximity service communication is not employed.

Optionally, the proximity service communication policy may further include a list of UE IDs of target UEs that can perform specific proximity service communication with the first UE, and the list is prioritized. For example, proSe Policy sent to the first UE includes { (ProSe identifier_1:UE2 ID,UE3 ID,UE4 ID), (rsc_1: UE3 ID, UE5 ID) }, for indicating to the first UE proximity services identified by ProSe identifier_1, and preferentially selecting UE2, UE3, and UE4 in order for proximity services communication; for the relay mode adjacent service identified by RSC_1, the UE3 and the UE5 are sequentially and preferentially selected as relay UE.

Specifically, if the first functional entity is a PCF, after determining the proximity service communication policy, the PCF may further send the proximity service communication policy to the first UE, and after receiving the proximity service communication policy, the first UE may execute the received proximity service communication policy, and specifically, the first UE may perform proximity service communication on a service indicated to use proximity service communication in the proximity service communication policy. Further, if the proximity service communication policy further includes a list of UE IDs of UEs that can perform specific proximity service communication with the first UE, for example { (ProSe identifier_1:UE2 ID,UE3 ID,UE4 ID), (rsc_1: UE3 ID, UE5 ID) }, then: for the proximity service identified by ProSe identifier_1, UE2 is preferentially selected for proximity service communication, if UE2 cannot be selected for some reasons, for example, the first UE detects that the UE2 radio signal is weak (for example, below a set threshold), UE3 is selected, and so on. For trunking mode proximity services identified by rsc_1, UE3 is preferred, and if UE3 cannot be selected for some reason, for example, the first UE detects that UE3 has a weak radio signal (e.g., below a set threshold), then UE5 is selected.

Specifically, after determining the proximity service communication policy, the proximity service communication of the first UE may be directly controlled according to the proximity service communication policy, so that the first UE performs proximity service communication with at least one target UE; or sending the proximity service communication policy to the third functional entity DDNMF, where the DDNMF controls proximity service communication of the first UE according to the proximity service communication policy, so that the first UE performs proximity service communication with at least one target UE.

Optionally, if the first functional entity is an AF, the AF may further determine a proximity service communication parameter (or a set of proximity service communication parameters) for a specific application according to the acquired proximity service communication analysis information, and send the proximity service communication parameter to the PCF, so that the PCF may perform one of the following:

1) The PCF determines a proximity service communication policy of the first UE based on the proximity service communication parameters for the particular application and sends the proximity service communication policy to the first UE. The proximity service communication policy of the first UE includes proximity service communication parameters for a specific application.

The proximity service communication policy of the first UE may further include a UE ID list of a UE capable of performing specific proximity service communication with the first UE, and the UE ID list is prioritized. For example, proSe Policy sent to the first UE (i.e. UE 1) includes { (ProSe identifier_1:UE2 ID,UE3 ID,UE4 ID), (rsc_1: UE3 ID, UE5 ID) } for indicating to UE1 proximity service identified by ProSe identifier_1, and preferably selecting UE2, UE3, and UE4 in order for proximity service communication; for the relay mode adjacent service identified by RSC_1, the UE3 and the UE5 are sequentially and preferentially selected as relay UE.

Further, the UE performs the received proximity service communication policy. Wherein the first UE adopts proximity service communication for a specific service (and/or application) according to proximity service communication parameters for the specific application in the proximity service communication policy. Namely: for a particular service (and/or application), proximity service communications are employed at a specified time, in a specified area (and/or location), and/or within a specified proximity service communication range, and specified QoS parameters or QoE parameters (and/or targets) are set.

Further, if the proximity service communication policy further includes a list of UE IDs of UEs that can perform specific proximity service communication with the first UE, for example { (ProSe identifier_1:UE2 ID,UE3 ID,UE4 ID), (rsc_1:ue3 ID, UE5 ID) }, then: for the proximity service identified by ProSe identifier_1, preferentially selecting UE2 for proximity service communication, if UE2 cannot be selected for some reasons, for example, UE1 detects that the UE2 wireless signal is weak (for example, lower than a set threshold), then selecting UE3, and so on; for trunking mode proximity services identified by rsc_1, UE3 is preferred, and if UE3 cannot be selected for some reason, for example, UE1 detects that UE3 radio signal is weak (e.g., below a set threshold), then UE5 is selected.

2) The PCF determines a proximity traffic communication policy based on the proximity traffic communication parameters for the particular application and sends the proximity traffic communication policy to the DDNMF. The proximity service communication policy includes proximity service communication parameters for a specific application.

Further, the DDNMF performs the received proximity service communication policy. The DDNMF, when receiving a Direct Discovery (Direct Discovery) request message of a first UE (e.g., UE 1) according to proximity service communication parameters of a specific application in a proximity service communication policy, discovers one or more target UEs capable of performing proximity service communication with the UE1 in a designated time, a designated area (and/or location) and/or a designated proximity service communication range for a specific service (and/or application), and sends information of the target UEs to the UE1 with the response message; meanwhile, the response message also carries the QoS parameters or QoE parameters (and/or targets) of the specific service (and/or application) specified in the adjacent service communication strategy. And the UE1 establishes proximity service communication with one or more target UEs according to the information carried in the response message.

Optionally, the AF may also send the proximity service communication parameters to the first UE after determining the proximity service communication parameters (or the set of proximity service communication parameters) for the specific application. Alternatively, the AF may send the proximity service communication parameter (or the proximity service communication parameter set) to the first UE through the application layer.

Further, the first UE application receives a proximity service communication parameter (or set of proximity service communication parameters) for the particular application. Wherein the first UE may employ proximity service communication for a particular service (and/or application) in accordance with a proximity service communication parameter (or set of proximity service communication parameters) for the particular application. Namely: for a particular service (and/or application), proximity service communications are employed at a specified time, in a specified area (and/or location), and/or within a specified proximity service communication range, and specified QoS parameters or QoE parameters (and/or targets) are set.

Optionally, the AF may also send the proximity service communication parameters to the DDNMF after determining the proximity service communication parameters (or set of proximity service communication parameters) for a particular application. Specifically, the AF may transmit the proximity service communication parameter (or the proximity service communication parameter set) to the NEF, which in turn transmits the proximity service communication parameter (or the proximity service communication parameter set) to the DDNMF.

Further, the DDNMF, upon receiving a Direct Discovery (Direct Discovery) request message of a first UE (e.g., UE 1), discovers one or more target UEs that can perform proximity service communication with UE1 within a specified time, a specified area (and/or location) and/or a specified proximity service communication range for a specific service (and/or application) according to proximity service communication parameters (or a set of proximity service communication parameters) for the specific application, and sends the target UE information to UE1 with the response message; meanwhile, the response message also carries QoS parameters or QoE parameters (and/or targets) of specific services (and/or applications) specified in the proximity service communication parameters (or proximity service communication parameter sets). And the UE1 establishes proximity service communication with one or more target UEs according to the information carried in the response message.

Alternatively, the AF may set the following proximity service communication parameters for a specific application according to the proximity service communication analysis information:

for a particular application:

1) Proximity service communication range (e.g., within an area of 100 meters radius centered on the UE);

2) QoS or QoE requirements of neighboring traffic;

3) The effective time of the proximity service communication;

4) Proximity to the area/location of traffic communication.

That is, for a particular service (and/or application), it is required or recommended to employ proximity service communications within a specified time, specified area (and/or location), and/or specified proximity service communication range, and to meet specified QoS/QoE requirements.

Specifically, if the first functional entity is DDNMF, before sending the proximity service communication analysis request to NWDAF, the DDNMF may further receive a proximity service request message sent by the first UE, so as to request information of the target UE or information required for requesting proximity service communication. Alternatively, the proximity service request message may be a Direct Discovery (Direct Discovery) request message of the proximity service.

Optionally, if the DDNMF receives the proximity service request message sent by the first UE, the DDNMF may set a corresponding parameter in the proximity service communication analysis request (for example, set Application id=prose identifier_1 or rsc_1) according to a proximity service identifier (ProSe identifier) or a relay mode proximity service identifier (i.e. a relay mode proximity service code RSC) carried in the direct discovery request message.

Optionally, the DDNMF further determines, for one or more UEs supporting a specific proximity service (including non-relay proximity service, relay mode proximity service, one or more of the following UE states or capabilities:

1) Communication performance;

2) Available resources;

3) Relay performance;

4) Mobility performance;

5) UE location or relative location.

Further, the DDNMF may determine a prioritized list of UEs supporting proximity services communication according to the UE status or performance described above. For example, { (ProSe identifier_1:UE2 ID,UE3 ID,UE4 ID), (rsc_1: UE3 ID, UE5 ID) } for indicating proximity service identified by ProSe identifier_1, UE2, UE3, UE4 are preferentially selected in order for proximity service communication; for the relay mode adjacent service identified by RSC_1, the UE3 and the UE5 are sequentially and preferentially selected as relay UE.

Further, the DDNMF may send a Direct Discovery (Direct Discovery) response message to the first UE, where the Direct Discovery response message carries information of UEs supporting proximity service communication.

Optionally, the direct discovery response message carries: for each UE supporting proximity services communication, one or more of the following UE status or performance information: 1) Communication performance; 2) Available resources; 3) Relay performance; 4) Mobility performance; 5) UE location or relative location. Or, the direct discovery response message carries a prioritized UE list supporting proximity service communication.

Further, the first UE determines to establish proximity service communication with one or more UEs according to the information carried in the direct discovery response message. Optionally, the first UE selects, as the relay UE, the UE with the best performance (e.g., communication performance) and sufficient available resources (e.g., 45% of the resources available) to establish direct communication, or the UE with the best relay performance and sufficient available resources (e.g., 45% of the resources available), depending on one or more status or performance information of the respective UE. Or if the direct discovery response message carries a prioritized UE list supporting proximity service communication, the first UE preferentially selects the UE with the high priority to establish proximity service communication.

Specifically, if the first functional entity is the first UE or the DDNMF, after determining the proximity service communication policy, the proximity service communication policy may also be executed, that is, proximity service communication or proximity service discovery is performed according to the proximity service communication policy, so as to implement that the first UE successfully establishes proximity service communication with at least one target UE.

Specifically, after determining the proximity service communication policy, the first UE may use proximity service communication with the at least one target UE according to indication information for indicating that proximity service communication is used in the proximity service communication policy, or use relay communication with the at least one target UE according to indication information for indicating that proximity service communication is used in the relay mode; proximity service discovery or proximity service communication is performed at a specific time, in a specific area, for a specific service (or application), and/or using specific QoS parameters according to information of a target application of the proximity service communication, an area of the proximity service communication, a quality of service QoS parameter of the proximity service communication in the proximity service communication policy. If there is a target UE supporting one or more specific services according to the proximity service communication policy, proximity service communication may be employed for the specific service, otherwise proximity service communication is not employed.

Specifically, after determining the proximity service communication policy, the DDNMF may, according to the proximity service communication parameters for a specific application in the proximity service communication policy, discover, for a specific service (and/or application), one or more target UEs that may perform proximity service communication with the UE1 within a specified time, a specified area (and/or location), and/or a specified proximity service communication range when receiving a Direct Discovery (Direct Discovery) request message of a first UE (for example, UE 1), and send information of the target UEs to the UE1 in a response message; meanwhile, the response message also carries the QoS parameters or QoE parameters (and/or targets) of the specific service (and/or application) specified in the adjacent service communication strategy. And the UE1 establishes proximity service communication with one or more target UEs according to the information carried in the response message.
