Users of Operators A, B, and C can access Operator X's 5G core network and establish sessions through Operator X's RAN.
[0040] The inventors noted that because there is no corresponding billing scheme for indirect network sharing deployments, it is impossible to provide billing services to indirect network sharing users.
[0041] Accordingly, this disclosure provides a billing processing method that can provide billing services to indirect network sharing users.
[0042] Figure 2 This is a schematic flowchart illustrating a billing processing method according to an embodiment of the present disclosure. In some embodiments, the following billing processing method is performed by an AMF network element in a managed operator network, including steps 21-22.
[0043] In step 21, during the user equipment registration management process, the network identifier of the user equipment is obtained.
[0044] In some embodiments, the network identifier of a user equipment includes the PLMN (Public Land Mobile Network) identifier of the user equipment.
[0045] In step 22, when the network identifier indicates that the user equipment is an indirect network sharing user and the predetermined conditions are met, a billing data request related to registration management is provided to the first CHF (Charging Function) network element in the managed operator network and the second CHF network element in the participating operator network. The user equipment belongs to the participating operator network, and the billing data request includes billing information related to the user equipment, so that the first CHF network element creates a first CDR (Charging Data Record) related to registration management, and the second CHF network element creates a second CDR related to registration management.
[0046] In some embodiments, the AMF network element has interconnection interfaces with both the first CHF network element and the second CHF network element. In this case, the AMF network element sends the aforementioned billing data request to the first CHF network element, and also sends the aforementioned billing data request to the second CHF network element.
[0047] In some embodiments, the AMF network element has an interconnection interface with the first CHF network element, and the first CHF network element and the second CHF network element have an interconnection interface. In this case, the AMF network element sends the aforementioned billing data request to the first CHF network element, and the first CHF network element sends the received aforementioned billing data request to the second CHF network element.
[0048] It should be noted that the AMF network element, as a Charging Trigger Function (CTF) network element, needs to collect billing information to provide to the first CHF network element and the second CHF network element.

[0050] In some embodiments, registration management includes registering a user equipment with a managed operator network or deregistering a user equipment with a managed operator network.
[0051] For example, in the case of registering user equipment with a hosting operator network, the aforementioned predetermined conditions include the user equipment completing the registration with the hosting operator network.
[0052] For example, in the case of registration management for user equipment to register with the hosting operator network, the aforementioned predetermined conditions include the user equipment completing the registration with the hosting operator network.
[0053] In the billing processing method provided in the above embodiments of this disclosure, during the registration management process of user equipment, if the user equipment is an indirect network sharing user and predetermined conditions are met, the AMF network element in the managed operator network provides a billing data request related to registration management to the first CHF network element in the managed operator network and the second CHF network element in the participating operator network. This allows the first CHF network element to create a first CDR related to registration management, and the second CHF network element to create a second CDR related to registration management, thereby providing billing services to the indirect network sharing user.
