A method of interpreting an authorization token is described herein. The service can receive an authorization token from a client device, and validate a signature of the authorization token. The service can identify an allowed function value associated at least part of an entitlement representation contained in a body of the authorization token. The service can convert the allowed function value to an allowed function bitmask that includes bits at a plurality of bit positions that are set to values indicating whether the subscriber element has attributes associated with each of the plurality of bit positions on a predefined attribute list. The service can determine whether the allowed function bitmask indicates that the subscriber element has one or more qualifying attributes that entitle a user of the client device to access the service.

A method, user device, and computer-readable storage media for registering and activating accounts is provided. A method includes: transmitting, by a user device to a computing system, an input from a user regarding opening an account at an institution associated with the computing system; establishing, by the user device, a communication session based on exchanging encryption keys between the user device and the computing system; in response to establishing the communication session, automatically installing, by the user device, a client application; displaying, via the client application on the user device, a graphical user interface (GUI) comprising a request for a user verification; transmitting, by the user device via the communication session, a received user verification to the computing system; and receiving, by the user device, an indication of an activation of the account at the institution from the computing system.

Asynchronous and/or synchronous zero charge telephony protocol systems and methods may include an asynchronous signaling switch and/or a call duration time quota from a synchronous charging onset to place and complete a call. A call request is received with a second device mobile address. The asynchronous systems include instructions to automatically modify the mobile address with a routing prefix when the first device has insufficient balance or independent of balance, route to the asynchronous signaling switch based on an associated modified address trunk path, revert to the call signal at the asynchronous signaling switch, and deliver and automatically disconnect the call immediately when the call is completed. The synchronous systems include instructions to automatically set the call duration time quota upon insufficient balance, and deliver and automatically disconnect the call from the second user mobile device when the call is completed and the call duration time quota is exceeded.

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.

A user equipment strategy configuration method and apparatus, a user equipment, a base station, and a storage medium are provided. The method includes: in an idle state, a user equipment sends an RRC establishment request to a base station; the user equipment sends an NAS message to the base station, wherein at least one of the RRC establishment request and the NAS message comprises a preset parameter, and the preset parameter indicates use for configuring a user equipment strategy; and/or in a connected state, send the NAS message to the base station by means of an SRB, wherein the NAS message comprises the preset parameter, and the preset parameter indicates use for configuring the user equipment strategy.

A transaction processing platform capable of facilitating the distribution to consumers of various types of prepaid products is disclosed. The transaction processing platform is configured to interface with one or more providers of such prepaid products in order to facilitate the procurement or activation of the products. The platform includes a conduit interface through which service request messages are received and respectively utilized to generate transaction requests for corresponding types of prepaid services. A supply interface arrangement, operatively coupled to the conduit interface, is configured to route a first of the transaction requests through a first supply interface associated with a first type of prepaid service. The supply interface arrangement also routes a second transaction request through a second supply interface associated with a second type of prepaid service. The platform is also configured to provide supplier response information received through the supply interfaces to the conduit interface.

Disclosed are a service data transmission method, a terminal and a charging system, and a computer storage medium. The method comprises: when detecting that a terminal roams from a local place to a different place, requesting and acquiring V-SIM card information about the different place from a V-SIM card server; disconnecting network connections which are established using a SIM card, and establishing network connections using the acquired V-SIM card information; and transmitting service data using the established network connections.

A method and system for least cost routing for mobile telephone calls between the United States and Mexico in such a way so that the call is separated into several call legs and the international portion or call leg is routed via a low-cost or no-cost route independently of the local call legs, essentially achieving an international call with local call rates. This uses a SIM card that automatically identifies any incoming or outgoing call and provides the ability to convert the call from an expensive international and/or roaming call to a local (free) call. Several slight variations are disclosed, and all embodiments have an integrated money transfer service that can be used with a very simple low-cost basic mobile phone using IVR, SMS and voice recognition, or can be accessed via the web or via a smartphone app.

A method of managing identities for use in a mobile telecommunications device in a telecommunications network has the following features. The identity management process is triggered and one or more parameters of a currently available mobile telecommunications network detected. An identity database is searchedeach record in the identity database comprises an identity and additional identity information for each identity. The additional identity information includes the one or more parameters. The identity management process involves selecting an identity when a first record comprising the one or more parameters detected is found in said searching and modifying an active identity of the mobile telecommunications device to be the selected identity when the active identity is not already the selected identity. This process can be carried out by a subscriber information module of a mobile telecommunications device.

Apparatuses, methods, and systems are provided for configuring a SIM-less System-on-Chip (S2oC) with integrated reprogrammable cellular network connectivity. Digitally issued Subscriber Identity Module (SIM) cards may be digitally issued by a remote server and downloaded and managed by the S2oC. A virtual SIM card container may be packaged in the S2oC and hosts an identity manager used by a plurality of applications residing in the multi-core processor of the S2oC. A virtual modem with a custom communication protocol allows the multi-core processor applications to exchange data with the virtual SIM card container.
