Techniques for allowing access based online charging in cases of multiple user agents (multi-UAs) scenarios where the instances are registered to different telephony application servers (TASs) are discussed herein. For example, a user device may support a native number and multiple virtual numbers linked via a user account. When servicing a call, the user device may determine a served number to service the call from. If the served number is not the native number but a virtual number, the native-line server may handle the call session, but the online charging session will be handled by the virtual-line server. The native-line server may use session initiation protocol (SIP) information to send updated information for charging parameters to the virtual-line server, including network access transfer for accuracy in online charging logic.

Methods, apparatus, and systems for the process-efficient generation of data records for data communications involving groups or aggregates of user equipment (UE), such as IoT devices, are described. In one illustrative example, for each one of a plurality of UEs associated with a group or aggregation identifier (ID), a request which includes data indicative of a network resource usage event of the UE is received and the data are stored in association with the group or aggregation ID. In response to identifying a predetermined condition, the data indicative of the network resource usage events associated with the group or aggregation ID are aggregated, and a request for generating a data record based on the aggregated data is sent to a data function for generating the data record. The generated data record (e.g. a CDR) may be stored for subsequent retrieval for reporting, analysis, network/communications management, or billing.

A method at a user equipment to facilitate activation and splitting of data billing between at least two parties, the method including starting, at the user equipment, a virtual subscriber identity module platform (‘VSP’) service on the user equipment; verifying VSP configuration information with a network server; upon verification, starting a data networking access point name (‘APN’) based on the configuration information on the user equipment; and setting a status indicator on the user equipment to indicate the VSP service is enabled.

Methods and apparatus that allow a device to migrate wireless service across multiple wireless networks. In one exemplary embodiment, the present invention enables storing and switching between multiple Electronic Subscriber Identity Modules (eSIM), where each eSIM is specific to a different carrier network. By loading the appropriate eSIM, the user device can authenticate itself with the selected carrier, rather than roaming. During roaming operation, the user equipment can load one or more of the previously stored eSIMs. Selection of the eSIM can be done manually by the user or can be driven by the user equipment based on desired context; for example, based on carrier signal strength, cost-effectiveness, etc. Support for multiple radio technologies also allows universal connectivity for wireless devices, even spanning previously incompatible technologies such as GSM (Global Standard for Mobile Communications), CDMA (Code Division Multiple Access), etc.

Various methods for selecting a network access subscription are provided. One example method includes receiving a request to participate in a communications session, determining that at least two subscriptions for network access are available, determining tariffs for one or more connection types that are available through each subscription, 5 determining cost factors for each connection type of the at least two subscriptions based on the tariffs, and selecting a target subscription and a target connection type for use in satisfying the request based on the cost factors. Similar and related example methods and example apparatuses are also provided.

A charge management system includes a user managing unit configured to manage pieces of user identification information for identifying users and pieces of terminal identification information for identifying transmission terminals, each piece of user identification information being associated with pieces of terminal identification information for identifying transmission terminals used by a user identified by the each piece of identification information; and a calculating unit configured to calculate a participation charge to each of the transmission terminals, bases on a total participation duration in which the each of the transmission terminals has participated in a conversation during a predetermined period, and calculate a total participation charge to each of the users by summing up the participation charges to transmission terminals specified by the pieces of terminal identification information associated with the each piece of the user identification information.

The invention relates to a human mobility measuring method comprising a structuring step where CDR raw metadata is filtered so as to identify a device identification, a cell site identification, a date, and a time; a data frame generating and sorting step where the filtered CDR metadata is sorted and the filtered sorted CDR metadata are projected into an occupancy grid comprising a location vs. time-bin matrix, a probabilistic map generating step of a device's location in space and time, and a filtering step to accurately represent human mobility from patterns that reflect errors, uncertainties, or patterns not related with real human mobility. The method further comprises a gap filling process allowing for a continuous localization of the device by extrapolating any trajectory in space and time of any device and a projecting step comprising projecting the trajectories defined at a Voronoi grid defined by the sites and towers to the road and street grid

Systems and methods discussed herein are directed to managing customer Subscriber Identity Module (SIM) and embedded SIM (eSIM) profiles and allocated Mobile Station International Subscriber Directory Numbers (MSISDN) for connected devices, e.g., cars, in different use-cases. For example, in configurations, users may have a primary electronic device, e.g., a mobile phone having a primary MSISDN.sub.PRIMARY that is instantiated on a primary Integrated Circuit Card Identifier (ICCID), ICCID.sub.PRIMARY in the billing system of a wireless communication network. When the user has a secondary device paired with the mobile phone, that secondary device may have a secondary MSISDN.sub.SECONDARY that is activated with a secondary ICCID.sub.SECONDARY in the billing system. Thus, the secondary device may be used by the user in conjunction with the primary device and is paired with the primary device such that incoming calls are forked to both the primary device and the secondary device.

A method, system and graphical user interface (GUI) for a mobile device, the GUI including: (a) at least one multifunctional button having at least two activation states: (i) a first state, when actuated, providing a basic function, and (ii) a second state, when actuated, providing an advanced function; whereby each of the activation states is actuated by a different user action; and (b) a plurality of calling accounts, each of the plurality of calling account being logically associated with a subscriber identity module (SIM) card or a direct inward dial (DID) number; wherein the at least one multifunctional button is configured to facilitate selection of one of the plurality of calling accounts in order to perform a communication event.
