A method for controlling data communication includes receiving a request to register a terminal to a communication network, allocating a virtual card to the terminal for data communication, acquiring data usage information of the virtual card, and controlling use or reallocation of the virtual card according to the data usage information. The data usage information includes an amount of data consumed by the terminal through using the virtual card.

Users may enroll one or more devices based on device information and a resource information associated with a resource. Such information and identifiers may be tokenized according to a hash algorithm to generate an enrolled user token. This enrolled user token may be utilized to verify communications and status changes of the user device. In response to a change of status of the user, similar information as that used to generate the enrolled user token, or at least a portion thereof, may be gathered from the user device and subjected to the same hash algorithm to generate a current user token. The current user token and the enrolled user token may be compared to determine if the user device is a spoofed device.

A modified telecommunications system is provided herein in which UEs can be associated with a user account using information other than SIM card data or a username and password combination. For example, when a subscriber activates a user account, the subscriber may be requested to provide a signature. A signature can include a unique PIN, a sample voice command, a fingerprint, a retinal scan, and/or the like. The signature may be stored in a data store in an entry corresponding to the user account. To associate a UE with a user account, the subscriber can provide a signature via the UE. The UE can then transmit the provided signature and a UE address to a management system. The management system can then store the UE address in the data store in an entry associated with the user account that corresponds with the provided signature.

A semiconductor integrated card includes an external package, a subscriber identification module (SIM) circuit, a plurality of SIM pins, a storage device and a plurality of memory pins. The SIM circuit is formed inside of the external package and is configured to store subscriber information. The SIM pins are formed on a surface of the external package and are electrically connected to the SIM circuit. The storage device is formed inside of the external package and is separated from the SIM circuit. The storage device includes a nonvolatile memory device. The memory pins are formed on the surface of the external package and are electrically connected to the storage device.

A method for revenue assurance in a telephone network. The method comprises receiving a call request from a first user device on a network to a second user device, where the user device associated with a first user account has an account credit value insufficient to complete the requested call. A call timer duration is set to instantly expire on encountering a chargeable event. The call is continued toward the second user device. Upon encountering a chargeable event, the call is released. The chargeable event may be presenting a Ring Back Tone to the caller and confirming that the second device is ringing. The chargeable event may be detecting when the call has been answered.

Systems and methods for managing a set of electronic assets from a single location are disclosed. The method includes providing a portal with a network security access control. The method includes determining that login credentials input to the access control are associated with a set of electronic assets corresponding to a plurality of third-party computing systems with application programming interface (API) gateways configured to accept API calls directed to changes in functionality of the electronic assets. The method includes presenting, via the portal, a virtual icon to identify a coordinated action with respect to the set of electronic assets and, in response to a selection of the virtual icon, executing a set of API calls that include an asset-specific API call to each third-party computing system in the plurality of third-party computing systems to implement the coordinated action on all electronic assets in the set of electronic assets.

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.

A method of signaling speech signal related text messages on board an aircraft, a computer program product for carrying out such a method, an apparatus for signaling speech signal related text messages on board an aircraft, and an aircraft comprising such an apparatus. A method embodiment comprises: providing a speech signal related to an announcement to passengers of an aircraft; obtaining a text message containing text corresponding to spoken words of the speech signal; and signaling the text message to one or more devices on board the aircraft.

Battery life of a user equipment (UE) can be extended when the UE is roaming internationally in a country that has multiple carrier networks each utilizing multiple public land mobile network (PLMN) identifiers. Scan control tables, stored in a universal integrated circuit card (UICC) of the UE, are populated with the identifiers of a PLMN having the highest priority in a defined area (e.g., Circle). A roaming control applet of the UICC can compare serving cell data with the scan control tables to determine if the UE is to perform a higher priority (HP) PLMN search. Utilization of the scan control table avoids unnecessary searches for HPPLMNs that are unavailable in the UE's current location and accordingly extends battery life of the UE.
