Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Before describing the information verification method provided by the embodiment of the present application in detail, a brief description is first given to an implementation environment related to the embodiment of the present application.

The information verification method provided by the embodiment of the application is applied to a service-oriented communication network architecture, and the interface protocol defined in the service-oriented communication network architecture provides more possibility for third-party service development. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a communication network architecture that may be applied to a car networking service using D2D technology, according to an example embodiment.

The communication Network architecture may include, but is not limited to, PCF (Policy Control Function) Network elements, UDM (User Data Manager) Network elements, AMF (Access and Mobility Management Function) Network elements, AF (Application Function) Network elements, NEF (Network export Function) Network elements, SMF (Session Management Function) Network elements, NG-RAN (New Generation-Radio Access Network, radio Access Network), and UE (User Equipment).

In the communication network architecture, the AMF may directly communicate with the PCF and the SMF, respectively, the AMF may directly communicate with the UE, the PCF may directly communicate with the UDM, the UDM may directly communicate with the AF, and the UDM may be provided with a UDR (Unified Data storage). The NG-RAN is respectively connected with the UE through a Uu interface, and the plurality of UEs are connected through a PC5 interface. Two adjacent UE can be in direct communication through a PC5 interface, and each UE is provided with a D2D direct connection layer. Each UE may have installed therein at least one application capable of triggering a message event of a discovery message, which may be referred to as a V2X application in some embodiments.

It should be noted that, the above is only described by taking the communication Network architecture as an example, in another embodiment, the communication Network architecture may further include other Network elements, for example, the communication Network architecture may further include an UPF (User Plane Function) Network element, an NRF (Network Function Repository Function) Network element, and the like, which is not limited in this embodiment of the present application.

In this embodiment, the AMF may be referred to as a mobility management network element, the policy control function network element and the session management function network element may be collectively referred to as a network function network element, and further, the network function network element is a 5G core network element, and the AF may be referred to as an application server.

After the communication network architecture related to the embodiments of the present application is described, the information verification method provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating an information verification method according to an exemplary embodiment, where the information verification method may be applied to the communication network architecture shown in fig. 1, and the method may include the following implementation steps:

step 201: the terminal equipment sends an information verification request to a network function network element, wherein the information verification request carries first application information of a first application needing to be verified.

The first Application information may be used to uniquely identify the first Application, and for example, the first Application information may be identified by an OS (Operating System) ID (Identification) and an APP (Application) ID; alternatively, the first application information may also be a predefined character string, and the like, which is not limited in this embodiment of the application.

As an example, when a certain service related to a first application needs to establish direct communication, a terminal device needs to be able to discover other terminal devices nearby in which the first application is installed, and for this purpose, a discovery message may be sent or a discovery message may be listened to. Before sending or listening, it is also necessary to verify whether the first application is capable of triggering a message event related to a discovery message, the message event including sending the discovery message or listening to the discovery message, i.e. whether the first application is capable of triggering a terminal device to send the discovery message or listen to the discovery message. As an example, the terminal device may send an information verification request carrying information of the first application that needs to be verified to the network function network element.

In a possible implementation manner, a specific implementation of sending, by the terminal device, the information verification request to the network function network element may include: and the terminal equipment packages the information verification request into a first transparent container, adds the first transparent container into a non-access stratum (NAS) message, sends the NAS message to a mobility management network element, and forwards the first transparent container to the network function network element by the mobility management network element.

Since a communication connection is established between the terminal device and a mobility management element (AMF) on the network side, and the mobility management element is connected to a network function element, in order to send the information authentication request to the network function element, the terminal device may send the information authentication request to a Non Access Stratum (NAS), and the NAS layer encapsulates the authentication request message into a first transparent container, encapsulates the first transparent container into a NAS message, and sends the NAS message to the mobility management element. The mobility management network element may directly forward the first transparent container to a network function network element without parsing after receiving the first transparent container.

It should be noted that, since the terminal device encapsulates the information verification request into the first transparent container and adds the first transparent container to the NAS message, the mobility management network element may not need to decode the content in the first transparent container, thereby reducing the operation burden of the mobility management network element.

As another example, the terminal device encapsulates the information verification request into an NAS message and sends the NAS message to the mobility management network element, and the mobility management network element parses the information verification request from the NAS message and forwards the information verification request to the network function network element.

In this implementation, the terminal device transmits the information verification request to the NAS layer, the NAS layer directly encapsulates the information verification request into an NAS message and then sends the NAS message to the mobility management network element, in this case, the mobility management network element parses the NAS message to parse the information verification request, and then sends the obtained information verification request to the network function network element.

It is worth mentioning that, in this implementation manner, since the terminal device is not required to perform the operation of encapsulating the information verification request into the first transparent container, but is directly encapsulated into the NAS message, the power consumption of the terminal device can be reduced.

As an example, the information verification request may further include group information indicating a group in which the first application is located; and/or, the information verification request may further include terminal device information of the terminal device; and/or the information verification request may also include user information.

Wherein the group identification can be used to uniquely identify a group. As an example, for the same application, if sessions of the same direct communication service are established among a plurality of terminal devices for the application, the plurality of terminal devices may be considered to belong to the same group, for example, to be grouped in a game. The terminal devices in the same group may be from the same PLMN (Public Land Mobile Network) or from different PLMNs. For example, a group includes 5 terminal devices, 3 of which may be terminal devices in PLMN1, 2 of which may be terminal devices in PLMN2, the terminal devices of 3 PLMNs 1 may communicate directly on the PC5 interface using D2D technology, and the terminal devices of 3 PLMNs 1 may also communicate with the terminal devices of 2 PLMNs 2 using a network. In some embodiments, in addition to requiring authentication of the first application, the group in which the first application resides may be authenticated to determine whether the group allows for message events that trigger discovery messages, and thus, the information authentication request may also include group information.

The terminal device information is used to uniquely identify the terminal device, and may be, for example, a GPSI (general Public subscriber Identifier). In some embodiments, a part of specific terminal devices may be limited to be capable of triggering a message event of a discovery message, so that the terminal device installed with the first application may be verified while verifying the first application, that is, the terminal device information may be carried in the information verification request to check whether the terminal device where the first application is located is capable of triggering a message event of a discovery message.

The user information may be used to uniquely identify a user in an application, and for example, the user information may be a user account. In some embodiments, the user account logged in to the first application may also be verified, that is, whether the user information allows a message event triggering a discovery message may be verified, and thus, the information verification request may carry the user information.

The information verification request is used to instruct the network functional network element to perform verification based on the first application information and the application verification information, and the specific implementation is as follows.

Step 202: the network function network element receives the information verification request.

Step 203: the network functional network element obtains application authentication information.

Wherein the application authentication information includes second application information of a second application capable of triggering a message event of the discovery message.

The second application is an application authorized to trigger a message event of the discovery message, and in the application authentication information, the authorized second application may include one or more applications, that is, the application authentication information includes at least one piece of second application information.

As an example, the application verification information further includes group information of a group in which the second application information is located, wherein each second application information is associated with at least one group information or each group information is associated with at least one second application information; and/or the application verification information further comprises terminal equipment information of terminal equipment used for installing the second application; and/or, the application authentication information further includes user information for logging in the second application.

As described above, in addition to the first application may be authenticated, at least one of group information, terminal device information, and user information related to the first application may need to be authenticated, and correspondingly, the application authentication information may include at least one of group information, terminal device information, and user information related to an authorized second application.

The association relationship between the second application information and the group information may include two types, one type is that the second application information is associated with at least one group information, that is, each group in at least one group related to the second application allows a message event that triggers a discovery message; another is that a certain group of information is associated with at least one second application information, i.e. each of the at least one second application within the certain group is allowed to trigger a message event of the discovery message.

As an example, the specific implementation of the network function network element obtaining the application verification information may include: and the network functional network element acquires the application verification information from the local.

The network function network element may locally store the application authentication information, and the locally stored application authentication information may be pulled from the user data management network element in advance.

As an example, the specific implementation of the network function network element obtaining the application verification information may further include: the network function network element obtains the application verification information from the user data management network element, and the application verification information in the user data management network element is sent by the application server in advance.

When the application authentication information is not locally stored in the network functional network element, the application authentication information may be pulled from the user data management network element. As an example, when the network function network element is a session management function network element, the session management function network element pulls the application authentication information from the user data management network element through the policy control function network element, that is, the policy control function network element needs to forward the application authentication information pulled from the user data management network element to the session management function network element at this time.

The origin of the application authentication information in the user data managing network element is briefly described here. In some embodiments, the application server may send application authentication information that can be applied to the discovery process performed on the PC5 to the user data managing network element, and further, the application server may send the application authentication information to the NEF, which sends the application authentication information to the user data managing network element. The user data management network element receives and stores the application authentication information sent from the application server, and further, the user data management network element can also store the application authentication information into the UDR.

Step 204: the network function network element performs authentication based on the first application information and the application authentication information.

Since the application authentication information includes the second application information of the second application capable of triggering the message event of the discovery message, the network function network element may detect, during the authentication process, whether the second application information in the application authentication information includes the first application information, if so, the authentication is passed, i.e., it indicates that the first application is capable of triggering the message event of the discovery message, and if not, the authentication is failed, i.e., it indicates that the first application is not capable of triggering the message event of the discovery message.

Further, when the information verification request further includes a group identifier, the group identifier needs to be verified, that is, whether the application verification information includes the group identifier in the information verification request is queried, and if the application verification information includes the group identifier, the verification is passed, and if the application verification information does not include the group identifier, the verification is not passed.

Further, when the information verification request further includes a terminal device identifier, the terminal device identifier also needs to be verified, that is, whether the application verification information includes the terminal device identifier in the information verification request is queried, if so, the verification is passed, and if not, the verification is not passed.

Further, when the information verification request further includes a user identifier, the user identifier also needs to be verified, that is, whether the application verification information includes the user identifier in the information verification request is queried, and if the application verification information includes the user identifier in the information verification request, the verification is passed, and if the application verification information does not include the user identifier, the verification is not passed.

That is, the application authentication information may correspond to information to be authenticated carried in the information authentication request, and when the application authentication information further includes a group identifier, it indicates that it is necessary to verify whether the first application can perform a discovery process on the PC5 interface, and also to verify whether a group corresponding to the group identifier allows the discovery process on the PC5 interface. Similarly, when the application authentication information includes the terminal device identifier, it indicates that it is necessary to verify not only whether the first application can perform the discovery process on the PC5 interface, but also whether the terminal device in which the first application is installed can perform the discovery process on the PC5 interface, and so on.

Step 205: sending a verification result of the first application information to the terminal equipment, wherein the verification result is used for indicating whether the first application can trigger a message event of a discovery message

And after the verification is finished, the network functional network element sends the verification result to the terminal equipment. Wherein the verification result may include a verification success message indicating that the first application is capable of performing the discovery process on the PC5 interface or a verification failure message indicating that the first application is not capable of performing the discovery process on the PC5 interface. Further, when the verification result includes the verification success message, the verification result may further include an application code, and the application code may be used by the terminal device for a secure transmission mechanism in a subsequent direct connection communication process. Further, when the verification result includes a verification failure message, the verification result further includes a failure reason, for example, the failure reason may include that the application is not allowed, the group is not allowed, or the terminal device is not allowed.

As an example, the specific implementation that the network function network element sends the verification result of the first application information to the terminal device may include the following two possible implementation manners:

the first implementation mode comprises the following steps: and the network function network element encapsulates the verification result into a second transparent container and sends the second transparent container to a mobility management network element, and the mobility management network element encapsulates the second transparent container into an NAS message and forwards the NAS message to the terminal equipment.

That is, in this implementation manner, the network function network element may perform an encapsulation operation on the verification result, that is, encapsulate the verification result into the second transparent container, and then send the second transparent container to the mobility management network element. After receiving the second transparent container, the mobility management network element may send the second transparent container to the NAS layer, and encapsulate the second transparent container in an NAS message by using the NAS layer, and send the NAS message to the terminal device. As an example, the mobility management network element may send the second transparent container to the terminal device via a UE configuration update message.

The second implementation mode comprises the following steps: and the network function network element sends the verification result to a mobility management network element, and the mobility management network element encapsulates the verification result into an NAS message and forwards the NAS message to the terminal equipment.

In this implementation, the network function element does not process the verification result, but directly sends the verification result to the mobility management element, and the mobility management element encapsulates the verification result into an NAS message and forwards the NAS message to the terminal device. As an example, after receiving the verification result, the mobility management network element may send the verification result to the NAS layer, and encapsulate the verification result into an NAS message by the NAS layer and forward the NAS message to the terminal device. Exemplarily, the mobility management network element may send the verification result to the terminal device through a UE configuration update message.

Step 206: the terminal device determines whether to execute a message event of the discovery message for the first application according to a verification result received from the network function network element.

And the terminal equipment receives a verification result fed back by the network function network element, wherein the verification result is used for indicating whether the first application can trigger a message event of a discovery message. As described above, since the network functional network element may send the verification result to the terminal device in different manners, correspondingly, the terminal device obtains the verification result in different manners, which may specifically include:

in the first case: in the first case of step 201, the terminal device receives the NAS message through the NAS layer, reads the second transparent container from the NAS message, and interprets the second transparent container to obtain the verification result.

In the second case: for the second case in step 202, the terminal device receives the NAS message through the NAS layer, and parses the NAS message, so as to obtain the verification result.

As an example, the terminal device may further receive the verification result through the D2D direct connection layer, and further, may feed back the verification result to the application layer.

The terminal device decides whether to execute the message event related to the discovery message according to the message included in the verification result, and it is understood that the message event related to the discovery message is executed when the verification result includes a verification success message, and the message event related to the discovery message is not executed when the verification result does not include a verification success message.

Next, for the case that the verification is successful, the operations performed by the terminal device are described as follows:

before introducing the operation executed by the terminal device, the layers included inside the terminal device and the inter-layer relationship are simply introduced. Referring to fig. 3, the terminal device may include an application layer, a D2D direct connection layer, and an access layer, where the interlayer relationship among the application layer, the D2D direct connection layer, and the access layer is as shown in fig. 3, where the access layer may directly transfer information with the application layer, that is, the D2D direct connection layer is not required to forward the information.

As an example, when the message event includes sending a discovery message, if the verification result includes a verification success message, the terminal device builds a discovery message through the D2D direct connection layer, and transfers the discovery message to the access layer; the terminal device adds the first application information as additional information of the discovery message through the access layer, and sends the added discovery message.

That is to say, when sending the discovery message, if it is determined that the first application can trigger sending the discovery message through verification, the terminal device builds the discovery message through the D2D direct connection layer, and then sends the discovery message to the access layer of the terminal device, and indicates that the message type is the discovery message. After receiving the discovery message, the access layer of the terminal device sets the first application information as additional information of the discovery message, for example, the first application information and the discovery message may be packaged, and then the access layer sends the packaged data to the terminal device on the receiving side. The first application information packaged by the access stratum of the terminal device may be preconfigured or sent by the application layer.

As an example, the message event includes an interception discovery message, and if the verification result includes a verification success message, the terminal device receives, through the access layer, the discovery message added with additional information, and detects whether first application information in the additional information is application information of an application that needs to be intercepted. And when the terminal equipment determines that the first application information is the application information of the application needing monitoring through the access layer, transmitting the first application information to the application layer or transmitting the first application information to the application layer through the D2D direct connection layer.

Corresponding to the sending end, when the terminal device is used as the terminal device of the receiving side, after being authorized to monitor the discovery message, the terminal device sends and receives the discovery message through the access layer. When receiving the discovery message, the access layer obtains the additional information of the discovery message, that is, obtains the first application information, and the access layer may determine whether the first application information is the application information of the application that needs to be monitored according to the preconfigured application detection information. If so, the access layer may directly send the first application information to the access layer, or the access layer sends the first application information to the D2D direct connection layer, and the D2D direct connection layer forwards the first application information to the application layer.

The preconfigured application detection information may be from an application layer, a D2D direct connection layer, or may also be from a network side. The specific implementation from the network side may refer to that the network function network element configures the application detection information for the terminal device, where the application detection information may be the same as the application verification information, or may be a subset of the application verification information. Further, the network function element may pull the application detection information from a user data management element.

Of course, the above is only described by taking the case that the additional information includes the first application information as an example, in another embodiment, the additional information may further include group information and the like, in this case, the application detection information in the terminal device at the receiving side further includes group information and the like of a group that needs to be monitored, at this time, it is further required to determine whether the group information in the additional information is the group information of the group that needs to be monitored, and after determining that the group information is the group information of the group that needs to be monitored, it is further required to feed back the group information to the application layer, and detailed description thereof is not repeated here.

As an example, if the message event includes sending a discovery message, if the verification result includes a verification success message, the terminal device constructs the discovery message through a D2D direct connection layer and then transmits the discovery message to an access layer, where the discovery message includes the first application information, and the terminal device sends the discovery message through the access layer.

If the message event includes sending a discovery message, the terminal device is a terminal device of a sending side. After the terminal device determines that the verification is passed, when the discovery message is built through the D2D direct connection layer, the first application information may be added to the discovery message, and then the discovery message including the first application information is sent through the access layer. Further, when the discovery message is constructed, in addition to the construction based on the first application information, the construction may be performed based on at least one of a group identifier, a terminal device identifier, and a user identifier.

As an example, if the message event includes a monitoring discovery message, if the verification result includes a verification success message, the terminal device receives the discovery message through the access layer, transmits the discovery message to the D2D direct connection layer, analyzes the discovery message through the D2D direct connection layer, and transmits the first application information to the application layer when it is determined that the first application information obtained after the analysis is application information of an application that needs monitoring.

That is, as shown in fig. 4, if the terminal device is a terminal device at a receiving end, after the discovery message is authorized to be monitored, the discovery message is received and sent through an access layer. Upon receiving the discovery message, the discovery message is passed to a D2D direct connection layer, and the D2D direct connection layer parses the discovery message to parse the first application information in the discovery message. Then, the D2D direct connection layer detects whether the first application information in the discovery message is application information of an application that needs to be monitored, as described above, the D2D direct connection layer may determine whether the first application information is application information of an application that needs to be monitored according to preconfigured application detection information. When the terminal device determines that the first application information in the discovery message is the application information of the application needing monitoring through the D2D direct connection layer, the first application information is transmitted to the application layer, and therefore the terminal device achieves a discovery process.

Further, the terminal device receives a discovery message through the access layer, detects whether first application information in the discovery message is application information of an application needing monitoring, transmits the first application information to the D2D direct connection layer when the terminal device determines that the first application information is the application information of the application needing monitoring through the access layer, and transmits the first application information to the application layer through the D2D direct connection layer.

That is to say, if the terminal device is a terminal device that receives information, after the discovery message is authorized to be monitored, the discovery message is received through the access stratum, and then it is detected through the access stratum whether the first application information in the discovery message is application information of an application that needs to be monitored. Similarly, the access stratum may determine whether the first application is application information of an application that needs to be monitored according to the preconfigured application detection information. The preconfigured information may be from an application layer, a direct connection layer, or from a network side. When the access layer determines that the first application is the application needing monitoring, the first application information is transmitted to the D2D direct connection layer and transmitted to the application layer by the D2D direct connection layer, or the access layer directly transmits the first application information to the application layer.

Further, the verification result includes configuration information of a timer, and the configuration information is used for indicating that the verification result is valid all the time in the running time period of the timer.

The configuration information may include a timing duration of the timer. That is to say, after the end of the verification, the network function network element may configure a timer for the terminal device, as an example, the network function network element may decide whether to configure the timer according to a local policy, and further, the network function network element may configure the timer according to the auxiliary information of the application server, that is, the auxiliary information may include configuration information of the timer. During the timer running period, the terminal device may use the verification result all the time, for example, the message event of the discovery message triggered multiple times by the same application or group does not need to be verified. Once the timer expires, the terminal device needs to reinitiate the authentication process.

As an example, the starting time of the timer includes at least one of:

(1) The time when the configuration information of the timer is received.

That is to say, the terminal device starts the timer once receiving the configuration information, and the running duration of the timer is the timing duration in the configuration information. It is understood that, since the configuration information of the timer is included in the verification result, it can also be understood that, when the verification result is received, the terminal device starts the timer.

(2) The time at which the restart timer command is received.

The restart timer command may be indicated by the network side, that is, in some cases, the terminal device may be required to restart the timer due to factors such as a change of the verification result, and the network side may issue a restart timer instruction at this time, and accordingly, the terminal device starts the timer.

(3) A time when the updated verification result is received.

When the verification result changes, which indicates that the current verification result has failed, in this case, the timer may be started, which is equivalent to performing timing anew.

It should be noted that, the above is only described by taking an example of configuring a timer by a network function network element, and in another embodiment, the timer may also be configured for the terminal device by a user data management network element according to a local policy or auxiliary information of an application server, which is not limited in this embodiment of the present application.

In the embodiment of the application, the terminal device sends first application information of a first application needing to be verified to a network function network element, the network function network element verifies whether the first application can trigger a message event of a discovery message, and feeds back a verification result to the terminal device, and the terminal device determines whether to execute the message event of the discovery message of the first application according to the fed-back verification result, so that information verification in a 5G system is realized.

In another embodiment, the terminal device may further perform authentication on the first application by using preconfigured application authentication information, and then details the implementation manner. Referring to fig. 5, fig. 5 is a flowchart illustrating an information verification method according to another embodiment, which may be applied to the communication network architecture shown in fig. 1, and the method may include the following implementation steps:

step 501: and the network function network element sends application verification information to the terminal equipment.

The application verification information comprises second application information of a second application capable of triggering a message event of the discovery message, and the message event is used for verifying whether the first application can trigger the discovery message or not by the terminal equipment based on the first application information of the first application needing verification, and comprises the steps of sending the discovery message and monitoring the discovery message.

Wherein the second application information of the second application may be used to uniquely identify the second application, and may be exemplarily identified by an OS ID and an APP ID; alternatively, the second application information may also be a predefined character string, which is not limited in this embodiment of the present application,

the second application is an application authorized to trigger a message event of the discovery message, and in the application authentication information, the authorized second application may include one or more, that is, the application authentication information includes at least one second application information.

As an example, the application verification information further includes group information of a group in which the second application information is located, wherein each second application information is associated with at least one group information or each group information is associated with at least one second application information; and/or the application verification information further comprises terminal equipment information of terminal equipment used for installing the second application; and/or the application authentication information further comprises user information for logging in the second application.

As an example, the network function network element encapsulates the application authentication information into a third transparent container and sends the third transparent container to the mobility management network element, and the mobility management network element adds the third transparent container to the NAS message and forwards the NAS message to the terminal device.

That is, in this implementation manner, the network function element may perform an encapsulation operation on the application authentication information, that is, encapsulate the application authentication information into the third transparent container, and then send the third transparent container to the mobility management element. After receiving the third transparent container, the mobility management network element may send the third transparent container to the NAS layer, and encapsulate the third transparent container in an NAS message by using the NAS layer, and send the NAS message to the terminal device.

As an example, the network function network element sends the application authentication information to the mobility management network element, and the application authentication information is encapsulated in an NAS message by the mobility management network element and then forwarded to the terminal device.

In this implementation, the network functional network element does not process the application authentication information, but directly sends the application authentication information to the mobility management network element, and the mobility management network element encapsulates the application authentication information into an NAS message and forwards the NAS message to the terminal device. As an example, after receiving the verification result, the mobility management network element may send the application verification information to the NAS layer, and encapsulate the application verification information into an NAS message by the NAS layer and forward the NAS message to the terminal device.

Further, when the terminal device is in a connected state with the mobility management network element, the mobility management network element may send the application verification information to the terminal device through a UE configuration update message.

Further, when the terminal device and the mobility management network element are in an unconnected state, that is, the terminal device is in an idle state, the mobility management network element may send the application verification information to the terminal device in the following manner: and receiving a service request or a registration request sent by the terminal equipment, wherein the service request or the registration request carries the capability information of the terminal equipment for executing the message event of the discovery message. If it is determined based on the capability information that the terminal device has the capability of performing the message event of the discovery message, the application authentication information is sent to the terminal device via a service response or a registration response, and if it is determined based on the capability information that the terminal device does not have the capability of performing the message event of the discovery message, a rejection message may be sent to the terminal device, which may carry a rejection reason.

Further, if the network function network element does not provide the application authentication information to the terminal device, it may be expressed as any one of the following cases: all applications can trigger a message event of a discovery message, or all applications cannot trigger a message event of a discovery message, or historical application verification information configured at the time closest to the current time is determined as application verification information, that is, the historical application verification information configured at the last time is adopted.

Further, for the network function network element, before sending the application verification information to the terminal device, the application verification information needs to be obtained, and the specific implementation of obtaining may include:

in the first case: and the network function network element acquires the application verification information from the local.

In the second case: the network function network element obtains the application verification information from the user data management network element, and the application verification information in the user data management network element is sent by the application server in advance.

When the application authentication information is not locally stored in the network functional network element, the application authentication information may be pulled from the user data management network element. As an example, when the network function network element is a session management function network element, the session management function network element pulls the application verification information from the user data management network element through a policy control function network element, that is, the policy control function network element needs to forward the application verification information pulled from the user data management network element to the session management function network element at this time. Further, if the user data managing network element does not have application authentication information, the application authentication information may not be provided.

Step 502: the terminal device receives and stores the application authentication information.

As an example, the specific implementation that the terminal device receives the application verification information may include: and the terminal equipment receives a UE configuration updating message sent by the mobility management network element, wherein the UE configuration updating message carries application verification information.

As an example, the specific implementation that the terminal device receives the application verification information may further include: the terminal equipment sends a service request or a registration request to the mobility management network element, wherein the service request or the registration request carries the capability information of the terminal equipment for executing the message event of the discovery message, the terminal equipment receives a service response or a registration response sent by the mobility management network element, the service response or the registration response carries the application verification information, and the application verification information is sent by the mobility management network element after the mobility management network element determines that the terminal equipment has the capability of executing the message event of the discovery message based on the capability information.

Further, for the terminal device, when the terminal device does not receive the application verification information, it is determined that all applications can trigger a message event of the discovery message; or, when the terminal device does not receive the application verification information sent by the network function network element, determining that all applications cannot trigger a message event of a discovery message; or, determining the preconfigured authentication information as application authentication information; or, determining the historical application verification information configured at the time closest to the current time as the application verification information, that is, determining the historical application verification information configured at the last time as the application verification information.

It should be noted that, the above describes a process of configuring application authentication information for a terminal device by a network function network element, and based on the above implementation, when the terminal device authenticates first application information that needs to be authenticated, the terminal device may perform authentication according to the application authentication information that is configured in advance.

Step 503: and the terminal equipment verifies the first application to be verified based on the application verification information.

When the first application needs to be verified, the terminal device may acquire application verification information and first application information of the first application that needs to be verified.

As an example, the first application needs to be verified when a certain service related to the first application is activated at the application layer or when there is a specific set-up in the first application. As an example, the application layer of the terminal device may send the first application information of the first application to the D2D direct connection layer.

Step 504: and the terminal equipment determines whether to execute the message event of the discovery message of the first application according to the verification result.

That is, the terminal device verifies whether the first application can trigger the message event of the discovery message based on the first application information and the application verification information.

As an example, the terminal device may be authenticated through a D2D direct layer. Illustratively, the D2D direct layer of the terminal device verifies whether the first application information is authorized to trigger a message event of the discovery message based on the application verification information. Further, the D2D direct layer of the terminal device verifies, based on the application verification information, whether the first application information and the group identity are authorized to trigger a message event of the discovery message. Further, the D2D direct layer of the terminal device verifies the first application information and the group identity and whether the terminal device is authorized to trigger a message event of the discovery message based on the application verification information. Further, the D2D direct layer of the terminal device verifies the first application information and whether the terminal device is authorized to trigger a message event of a discovery message based on the application verification information, and so on.

The terminal equipment determines whether to execute the message event related to the discovery message according to the verification result, and can understand that when the verification is passed, the message event related to the discovery message is executed, and when the verification is not passed, the message event related to the discovery message is not executed.

In addition, for the operation executed by the terminal device in the case that the verification is successful, reference may be made to step 203 in the embodiment of fig. 2 described above, and details are not repeated here.

In this embodiment of the present application, when the terminal device needs to verify the first application, the application verification information preconfigured by the network function network element may be obtained, and since the application verification information includes the second application information of the second application that can trigger the message event of the discovery message, the terminal device may verify whether the first application can trigger the message event of the discovery message based on the first application information and the application verification information, thereby implementing information verification in the 5G system.
