Disclosed herein are various embodiments to prevent, detect, or take action in response to the moving a device credential from one device to another, the improper configuration of a service processor, a missing service processor, or the tampering with a service processor in device-assisted services (DAS) systems.

A mobile digital telecommunication system, a computer-implemented method, and a computer readable medium having stored thereon a computer executable program code for processing of usage detail records (UDRs) is disclosed herein. The mobile digital cellular telecommunication system comprises a network component configured to generate the UDRs, a rating system and a billing system.

A non-transitory computer-readable storage medium storing one or more machine-executable instructions that, when executed by one or more processors, cause the one or more processors to: determine whether a traffic flow of a wireless end-user device is associated with a first service activity, the traffic flow comprising one or more attempted or successful communications over a wireless access network; if it is determined that the traffic flow is associated with the first service activity, create a first data record, the first data record identifying the first service activity; if it is determined that the traffic flow is not associated with the first service activity, determine whether the traffic flow is associated with a second service activity; and if it is determined that the traffic flow is associated with the second service activity, create a second data record, the second data record identifying the second service activity.

A system, method, and computer program product are provided for managing a shared quota for a plurality of network subscribers in a consumer telecommunications network. In use, a first usage quota reservation out of a shared quota is allocated to at least one first subscriber among a plurality of network subscribers. Further, it is determined that at least a portion of the shared quota is available. Additionally, a progressively smaller at least one second usage quota reservation out of the at least a portion of the shared quota is recursively allocated to the at least one first subscriber among the plurality of network subscribers, the smaller at least one second usage quota reservation being smaller than the first usage quota reservation out of the shared quota.

Device assisted CDR creation, aggregation, mediation and billing is provided. In some embodiments, device assisted CDR creation, aggregation, mediation and billing for a wireless network includes collecting device generated service usage information for one or more devices in wireless communication on the wireless network; and providing the device generated service usage information in a syntax (e.g., a device assisted charging data record (CDR)) and a communication protocol (e.g., 3GPP, 3GPP2, or other communication protocols) that can be used by other network devices to augment or replace network generated service usage information for the one or more devices in wireless communication on the wireless network.

A pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein achieve a method and system for providing a network-based northbound application programming interface. The method includes receiving, by an API provider, a request for invoking one or more service APIs from one or more API invoker clients. The method includes utilizing, by the API provider, a CAPIF core function residing at a first domain to provide the one or more service APIs. The method includes providing, by the API provider, the one or more service APIs to the one or more API invoker clients through the CAPIF core function, wherein the API provider comprises one or more service APIs, an API exposing function, an API publishing function and an API management function.

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.
