Systems and methods for direct ledger reporting of user equipment (UE) data usage for telecommunications networks are provided. Embodiments of the present disclosure, at least in part, assess telecommunications network data usage by decentralizing the tasks of monitoring and collecting data regarding the types and quantity of data usage, delegating those tasks to data usage record synthesizers that are instantiated at, or close to, the point and/or device where the data is being consumed. In some embodiments, assessing data usage may include determining a classification of an instance of UE network data usage based on data packet traffic; determining ledger record data for inclusion in one or more fields of a ledger record based on the classification; generating a ledger record based on the one or more fields of ledger record data; and transmitting the ledger record via the telecommunications network for recording to an immutable data usage ledger.

A user equipment with a primary identifier and a secondary identifier. The user equipment comprises a witness application stored in the memory, that when executed by the processor in a trusted security zone, wherein the trusted security zone provides hardware assisted trust, transmits a message comprising the logs of the communication service consumption to a server in a network of a service provider associated with the user equipment using a trusted end-to-end communication channel, wherein the logs are translated by the server to a format compatible with a billing data store supported by a billing server, wherein the translated logs are transmitted to the billing data store, whereby a bill is created for each of the primary identifier and the secondary identifier by the billing server accessing the billing data store.

Methods and apparatus, including computer program products, are provided for charging in multi-connectivity systems. In some example embodiments, there may be provided a method that includes marking, by a first base station serving a user equipment, at least one packet to include a first indication indicating that the at least one packet was received directly at the first base station serving the user equipment; and marking, by the first base station, at least one other packet to include a second indication to indicate that the at least one other packet was received via a second base station also serving the user equipment. Related systems, methods, and articles of manufacture are also described.

A device may determine a subscriber identifier associated with a subscriber device. The device may obtain a service indicator based on the subscriber identifier. The service indicator may identify a network service to which a subscriber, associated with the subscriber identifier, is subscribed. The device may obtain a charging data function (CDF) identifier based on the service indicator. The CDF identifier may identify a destination CDF for charging messages associated with the network service. The device may establish a communication session associated with the subscriber device and the network service. The device may transmit one or more charging messages, associated with the communication session, to the destination CDF identified by the CDF identifier.

The present disclosure generally relates to systems, methods, and computer-readable media for managing the generation and processing of charging data records (CDRs) in a telecommunication environment (e.g., a fourth generation (4G) a fifth generation (5G), or future generation mobile network). The systems described herein involve predicting lengths of CDRs prior to encoding and providing the CDRs to a charging gateway function to ensure that the CDRs do not exceed a maximum allowable length that the charging gateway function is capable of processing while also reducing the total number of CDR packages that are encoded and transmitted. Indeed, the systems described herein can predict the length of the CDRs incrementally as charging containers are added, thus limiting the number of CDRs that are generated and processed.

A message transmission method and a core network interface device are provided, so as to reduce complexity of a communication interaction between a core network and each external entity. After receiving a request message from a service instance, obtains device indication information of a target device, an identifier of the service instance, and a type of a response message corresponding to the request message; after sending the request message and receiving a to-be-forwarded response message, obtains a type of the to-be-forwarded response message and device indication information of a device that sends the to-be-forwarded response message; sends the to-be-forwarded response message to the service instance when the type of the to-be-forwarded response message and the device indication information of the device that sends the to-be-forwarded response message respectively match the type of the response message and the device indication information of the target device that correspond to the request message.

The mobile device stores a plurality of communication profiles comprising one or more local communication profiles and a global communication profile. The mobile device determines local access requirements for connecting to a local cellular network operator and determines whether the plurality of communication profiles comprises a local communication profile that satisfies the local access requirements. When the plurality of communication profiles does not comprise a local communication profile that satisfies the local access requirements: the mobile device connects to a global cellular network operator using the global communication profile; receives, from the global cellular network operator, a new local communication profile that satisfies the local access requirements and connects to the local cellular network operator using the new local communication profile. Subsequently, the mobile device communicates with another device via the local cellular network operator as if the mobile device was a local mobile device.

Examples disclosed herein involve receiving a request from a calling device to establish a communication session between a mobile device and the calling device, the mobile device assigned a virtual telephone number, retrieving location information corresponding to a location of the mobile device from a location register, and sending a redirect to a session border controller (SBC) to establish the communication session between the calling device and the mobile device based on the location information.

A charging method, including sending, by a control plane gateway, a first charging trigger event to a user plane gateway, where the first charging trigger event triggering the user plane gateway to generate service usage information, generating, by the user plane gateway, the service usage information when the user plane gateway detects that the first charging trigger event occurs, sending, by the user plane gateway, the service usage information to the control plane gateway, generating, by the control plane gateway, a charging request according to the service usage information, and sending, by the control plane gateway, the charging request to a charging system. Offline charging during packet data network gateway (PGW) control and user (CU) separation is implemented.

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.
