Systems, methods, and apparatuses may include a Billing System (BS) node, Charging System (CS) node, and a mediation node for managing Mobile Station International Subscriber Directory Numbers (MSISDN)s for a telecommunication network. The system may make an MSISDN available for reassignment immediately or shortly after (e.g., seconds, minutes, days, or weeks after) receiving a cancelation request associated with the MSISDN. For instance, upon receiving the cancelation request, the system may store a line identifier with an association to the MSISDN and/or an International Mobile Subscriber Identity (IMSI) in a line identifier database, and the system may delete the MSISDN/IMSI from a user account database. The system may receive a Telephone Account Procedure (TAP) Call Detail Record (CDR) associated with the MSISDN/IMSI after receiving the cancelation request. Accordingly, the system may use the line identifier stored in the line identifier database to generate a billing report corresponding to the TAP CDR.

A charging function device may include a processor configured to obtain subscription information associated with a user equipment (UE) device in a wireless communication network. The processor may be further configured to receive, from a gateway device, data flow information relating to data flows associated with the UE device; receive, from a policy device, policy information relating to policies applied to the data flows associated with the UE device; generate a record for the UE device based on the received data flow information and the received policy information, wherein the record identifies at least one account charge based on a particular data flow associated with the UE device; and provide the generated charging record to an account system.

A system for preserving charging event messages in a mobile telecommunications network when a charging server is unavailable includes a message broker comprising persistent storage. The system also includes a network element that generates a charging event message, attempts to send the charging event message to a charging server, and writes the charging event message to the message broker in response to determining that the attempt to send the charging event message to the charging server has failed. The system also includes a replay agent that subscribes to the message broker for notifications associated with the charging server, receives a notification from the message broker about the charging event message, reads the charging event message from the message broker, and causes the charging event message to be sent to the charging server when the charging server is available.

The present disclosure method and device for wireless communications, comprising: operating a first data block set; and transmitting first charging information; a size of data in the first data block set is used to generate the first charging information, the first charging information comprises a first identity (ID) set, and the first ID set comprises a first ID and a second ID; the first ID is a link layer ID; the operating action is receiving, a destination ID field of a MAC header of a MAC PDU used to carry the first data block set comprises at least partial bits in a first ID, when a destination link layer ID list maintained by a node indicated by the second ID comprises the first ID. The present disclosure determines a receiver or a generator of a first data block set, which improves accuracy of charging and enriches charging types of services.

A system, method, and computer program are provided for processing a billing item. In use, a first dataset is collected including a plurality of records. The first dataset includes customer records, billing records (with billing item(s)) for each of the customers, and call incident records (with calling customer identification, billing record identification, and billing item identification). Additionally, a first AI-model is trained using the first dataset to recognize at least one pair of a first customer type and a first billing item type, and an associated first probability that such pair results in a call to the call-center. Further, a second dataset is collected including new billing records. The first AI-model is used to detect at least one billing record in the second dataset having probability higher than a redefined threshold probability that the customer associated with the billing record will call a call-center.

A first network element or an access network device determines, based on identification information of one or more terminals on which a first operation is performed and type information of the first operation, quantity information of the first operation that is performed, and the first network element sends charging information including the type information and the quantity information to a charging function network element.

There are provided measures for coordinated session charging in roaming scenarios. Such measures (of a first session management entity of a first mobile network in a roaming charging related scenario between said first mobile network and a second mobile network) exemplarily comprise transmitting a session creation request message to a second session management entity of said second mobile network, said session creation request message including information indicative of a first configuration utilized for mobile network related charging, and receiving a session creation response message from said second session management entity of said second mobile network, said session creation response message including information indicative of a second configuration utilized for mobile network related charging.

A communications system, a core network device and a non-transitory machine-readable medium are provided. In the communications system, a master base station gather traffic statistics information on a service of a user terminal which is transmitted between the user terminal and the master base station through a secondary base station, and sends a message to a core network device. The message includes the traffic statistic information for calculating a charge on the service by the core network device.

There are provided measures for coordinated session charging in roaming scenarios. Such measures (of a first session management entity of a first mobile network in a roaming charging related scenario between said first mobile network and a second mobile network) exemplarily comprise transmitting a session creation request message to a second session management entity of said second mobile network, said session creation request message including information indicative of a first configuration utilized for mobile network related charging, and receiving a session creation response message from said second session management entity of said second mobile network, said session creation response message including information indicative of a second configuration utilized for mobile network related charging.

A method for billing in a wireless communication system, according to an embodiment, includes: transmitting billing data to an upper entity; determining whether the billing data has been normally transmitted; and executing a supplementary operation based on a result of the determining.
