In one example, a charging filtering function may obtain a request for one or more rules that control whether or when one or more charging data records associated with a user equipment are to be provided to one or more billing systems. The request includes an identification of the user equipment. Based on the identification of the user equipment, the charging filtering function may identify the one or more rules. The charging filtering function may provide the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems.

Systems and methods that transport Charging Data Records (CDRs) using GTP′ for offline charging. One embodiment comprises a Charging Data Function (CDF) that communicates with a Charging Gateway Function (CGF) of an offline charging system using GTP′. The CDF assembles a GTP′ request for a transaction, assigns a sequence number for the transaction, and assigns a timestamp to the sequence number. The CDF inserts the sequence number in a GTP′ header of the GTP′ request, inserts the timestamp assigned to the sequence number in the GTP′ header of the GTP′ request, and sends the GTP′ request to the CGF.

The method includes obtaining charging related information of a proximity based service used by user equipment; generating a charging request for the proximity based service used by the user equipment based on the charging related information; and transmitting the charging request to a charging system of the wireless communication network.

Systems and methods are provided for processing messages in an Offline Charging System (OFCS) of a communications services provider. A front-end distributor unit receives Diameter messages from a Charging Trigger Function (CTF) and distributes the Diameter messages to Charging Data Function (CDF) units of the OFCS. The distributor unit receives Diameter response messages from CDFs and calculates performance metrics based on the distributed messages and their responses. The distributor unit computes revised distribution weights used for distributing new Diameter messages for new Diameter sessions to the CDF units based on the measured metrics, thus adjusting the distribution pattern of the Diameter messages based on estimated workload conditions at the CDFs.

Systems and methods described herein include receiving, at a network device and from a session management device, a first message that includes a first identifier associated with a subscriber and a second identifier associated with a first service that is charged using an online charging system. The network device transmits a second message that indicates a first time period in which to report data usage associated with the first service and a second time period in which to report data usage associated with one or more second services that are charged using an offline charging system. The network device receives first data usage information associated with the first service after the first time period and second data usage information associated with the one or more second services after the second time period. The network device processes the data usage information.

Systems, methods, and software of managing bandwidth allocated to User Equipment (UE). In one embodiment, a bandwidth management system collects cell load information for a plurality of cells within a Radio Access Network (RAN), and processes the cell load information to determine a cell load status for each of the cells. The system performs bandwidth throttling for the UE by determining a location of the UE, identifying the cell load status for one or more cells in a region of the RAN corresponding with the location of the UE, determining whether the region of the RAN is overloaded based on the cell load status, and controlling a downgrade of bandwidth allocated to the UE in the RAN responsive to a determination that the region is overloaded.

Embodiments of this application disclose a charging method and a related product. A charging function CHF apparatus receives a first charging request sent by a charging trigger function CTF apparatus, where the first charging request carries event charging information. Then, the CHF apparatus determines a first event charging processing mode based on the event charging information, and processes the first charging request according to the first event charging processing mode. According to the method, the CHF apparatus may determine the first event charging processing mode based on the first charging request, and perform event charging processing. Therefore, charging can be accurately and efficiently performed on an event charging service.

A method performed in a CP node. The method comprises setting a TQM in a URR to which its corresponding SDFs are applicable for envelope reporting, setting at least one reporting trigger in the URR, to instruct the UP function to generate a usage report upon closure of an envelope, setting a measurement method in the URR, to instruct the UP function to collect usage of volume, time and/or event, sending the set URR to the UP function, receiving one or more usage reports from the UP function, in response to the sent URR, wherein the received usage report(s) comprises at least a usage report trigger set to envelope closure, determining a starting time and/or an ending time for each envelope, based on the received usage report(s), and storing each envelope, with the determined starting time and/or ending time, for online or offline charging.

Systems and methods for performing offline charging for proximity services. One embodiment is a proximity service element that controls proximity services for a mobile network. The proximity service element receives a request from User Equipment (UE) for a proximity service, and collects offline charging information related to the proximity service. The proximity service element formats the offline charging information into an offline charging communication, and transmits the offline charging communication to an offline charging system.
