A method for providing mobile connectivity in a transportation vehicle with a cellular connectivity unit using a first subscriber identification module associated with a first subscription for a first Mobile Network Operator and at least a second subscriber identification module associated with a second subscription for a second Mobile Network Operator. A first Access Point Name interface and at least one further Access Point Name interface are configured, wherein both are related to the first subscriber identification module. The first Access Point Name interface is used for network registration and data transport of the cellular connectivity unit assigned to the first subscriber identification module. The at least one further Access Point Name interface is used for network registration and data transport of the cellular connectivity unit assigned to the second subscriber identification module.

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.

The disclosed embodiments include a method for offline charging performed by an anchoring node of a telecommunications network. The anchoring node can send a request to an online charging system (OCS), where the request is for online metering of a call by a subscriber of the telecommunications network. The anchoring node may obtain an indication of an exception to the online metering of the call. In response, the anchoring node can perform a default call handling (DCH) procedure to allow the call on the telecommunications network despite an inability to perform the online metering. The anchoring node also generates a modified charging detail record (CDR) that includes an indication of the exception. The anchoring node can then send a message, which includes at least an indication of the modified CDR, to enable a mediation server to perform offline charging for the call.

The present disclosure relates to a method for determining node metrics based on node field-value pairs and electronic activities. The method includes identifying a first node profile. The method includes identifying a plurality of electronic activities associated with the first node profile. The method includes identifying a first group of node profiles of a first category with a predetermined event. The method includes selecting a second group of node profiles. The method includes parsing the plurality of electronic activities to identify creation timestamps and participant characteristics of the electronic activities. The method includes generating an input array based on the timestamps and the participant characteristics. The method includes generating, for each of the second group of node profiles, a respective array. The method includes determining a probability score indicating a likelihood that the node profile belongs to the first category.

Secure architectures and methods for improving the security of mobile devices are disclosed. Also disclosed are apparatuses and methods to detect and mitigate fraud in device-assisted services implementations.

A communication system includes: a first communication apparatus configured to control a first wireless communication and a second wireless communication different from the first wireless communication; a second communication apparatus configured to communicate using the second communication; and a third communication apparatus configured to perform data communication with the first communication apparatus via the first wireless communication or the second wireless communication, wherein the third communication apparatus transmits to the first communication apparatus a control message that includes an available address of the third wireless communications apparatus used in the second wireless communication, the first communication apparatus notifies the second communication apparatus of the available address of the third communication apparatus, and the second communication apparatus communicate with the third communication apparatus using the address.

The present disclosure provides details on an intermediary service bureau (ISB) system which includes an ISB center that acts as an intermediary communication center between communication devices used by correctional facilities and contract providers. The ISB records communications, stores security data, and provides front end processing to facilitate an inmate to communicate with an outside party by way of a contract provider. Further, the ISB provides accounting services for inmates and friends and family that use services provided the contract provider. The contract provider provides security and routing services for the ISB by obtaining data from the ISB and updating data at the ISB according to the communications.

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 and method for incoming and outgoing RCS messages with inmates includes a database including a plurality of user records, wherein the user records include a plurality of user profiles and a plurality of inmate profiles, wherein each of the user profiles includes a user ID, a mobile ID, a carrier, and at least one inmate account number. Each of the inmate profiles includes an inmate user ID, a carrier, a current account balance, and at least one user account number. The system and method also includes an application server including a processor programmed to receive a RCS message from a new user profile, determine a carrier of the user profile, process the new user profile based on the carrier, wherein the carrier is determined by a triggering event, and send the new user profile to an appropriate list for future RCS messaging.

Various methods for a 3GPP defined Charging and Collection Function are employed that may use a microservices approach. The microservice approach may decompose the function of the network elements into component level functions that may be deployed as separate functional elements.
