A ProSe Direct Discovery procedure has been defined for such services to detect and identify UEs that are using evolved UMTS Land Surface Access (E-UTRA) direct radio signals. ProSe Direct Discovery can be an independent service, and can also initiate ProSe Direct Communication.

Currently, the International Standards Third Generation Partnership Project (3GPP) has defined Mode A ("I am here") of the direct discovery process between adjacent UEs described above, in which two UEs of different roles are defined: (Announcing) UE and Monitor (Monitoring) UE. The Announcing UE can broadcast information of interest to UEs that are close to the discovery capability; and the Monitoring UE can listen to information that is of interest to the Annanonce UE. FIG. 1 is a flow chart of direct discovery of mode A according to the related art. As shown in FIG. 1, the process may include the following steps:

Step S102: Perform a service authorization based on a Public Land Mobile Communication Network (PLMN) that can use ProSe Direct Discovery;

Step S104: If the UE is authorized as an announcer, the UE sends a discovery request for broadcasting to a ProSe Function.

Step S106: If the request is successful and the ProSe Application Code is obtained, the UE starts broadcasting on a preset interface (for example, a PC5 interface);

Step S108: If the UE is authorized as the listener, the UE sends a discovery request for the ProSe Function for monitoring;

Step S110: If the request is successful and the discovery filter composed of ProSe Application Code(s) or mask(s) is obtained, the UE starts to listen to the ProSe Application Code(s) on the PC5 interface;

In the related art, charging for direct discovery of neighboring UEs cannot be implemented. Using the method shown in FIG. 2, the ProSe direct discovery process for mode A increases the triggering timing of offline charging: that is, when the request message or the matching report message sent by the UE is successfully responded, according to the request message or the matching report message. The offline charging process is triggered, thereby solving the problem that the direct discovery of the neighboring UE cannot be performed in the related art, and the direct discovery of the neighboring UE is performed.

Step S302: Receive a request message or a matching report message sent by the user equipment UE, where the type of the request message is determined according to a role that the UE is authorized after being subjected to the service authorization process;

Step S304: trigger an online charging process according to the request message or the matching report message.

After the ProSe Function receives the discovery request of the Announcing UE, the ProSe Function triggers a credit control request (CCR) [Event] and carries information about the ProSe service, which may include, but is not limited to, at least one of the following: whether the ProSe-enabled UE has Public safety attributes, such as open or restrict, Discovery Model (mode A or mode B), UE identity (eg, International Mobile Subscriber Identity (IMSI)), UE Role (eg: Announcing UE), ProSe Application ID, ProSe Application Code, and timestamp.

After the ProSe Function receives the monitoring request from the monitoring UE, the ProSe Function triggers the CCR[Event] and carries the information about the ProSe service, which may include, but is not limited to, at least one of the following: whether the ProSe-enabled UE has public safety (Public safety) ) attribute, add discovery mode (open or restrict), discovery mode (Discovery Model) (ie mode A or mode B), UE identity (eg international mobile subscriber identity (IMSI)), role of the UE (eg: Announcing UE), ProSe Application ID, ProSe Application Code, and timestamp.

After the ProSe Function receives the matching report of the UE, the ProSe Function triggers the CCR[Event] and carries the information about the ProSe service, which may include, but is not limited to, at least one of the following: whether the ProSe-enabled UE has public safety (Public safety) Attributes, add discovery mode (open or restrict), discovery mode (Discovery Model) (ie mode A or mode B), UE identity (eg International Mobile Subscriber Identity (IMSI)), UE role (eg: Announcing) UE), ProSe Application ID, ProSe Application Code, and timestamp.
