The present disclosure relates to a method related to an online charging system for a cellular radio communication system. The method includes obtaining a notification that a refill action of a user account for the communication system is pending. The notification includes an identifier (vid) of a refill resource for the refill action. The method also includes inspecting a refill database updated by an account management function of the online charging system to determine whether the refill resource identifier is included therein, indicating whether or not the user account has been refilled based on the refill resource.

A system and method for providing top-up of mobile data, by processing one or more transactions between a data sponsor and a data beneficiary who is possibly being served by multiple data providers. The top-up can be based on i) an application program interface (API) call being made into the mobile network operator of a data user or ii) an API call being made into a sponsored data (SD) platform/system (SDS) to allocate a quota to the data user, among other possible product options. In the first option, provisioning of the data quota and consumption against the quota is managed directly by the mobile network operator itself. In the second option, allocation of the quota and consumption against the quota is managed by the SDS and an SD control app. The system can select a particular option because that option best meets one or more business goals or rules.

Methods, systems, and computer readable media for validating a redirect address in a Diameter message are disclosed. One method occurs at a Diameter node, e.g., a Diameter routing agent (DRA) node, a packet data network (PDN) gateway, a policy and charging enforcement function (PCEF) node, or a Diameter edge agent (DEA) node. The method includes receiving a message containing a redirect address that appears to be associated with a top-up server for facilitating a subscriber to recharge or top-up an account balance. The method also includes determining whether the redirect address is valid by querying, using a subscriber related identifier, a data structure containing one or more addresses. The method further includes performing at least one action based on the determining.

A method and system of detecting a delinquent mobile user device. An international mobile subscriber identity (IMSI) of a subscriber identity module (SIM) card of the user device is determined by the user device. The IMSI is sent to a Remote Recovery Server (RRS). A message is received from the RRS as to whether the IMSI is authorized for the user device. Upon determining that the IMSI is not authorized for the user device, a notification is displayed on a display of the user device.

A system for providing multimedia content. The system includes means for transmitting targeted multimedia content to customers via a telecommunications network; and automatically receiving and outputting the content on a mobile platform. In the illustrative embodiment, the system includes means for encoding, compressing and storing content on a server. An applet is transmitted from the server to each mobile platform. When executed at the mobile platform, the applet deciphers the content and retrieves a schedule with a playback time. The content is then played out without interrupting the user. The applet may include credit code which adds time to a SIM card on the mobile platform giving a user credit time to use the device for one or more functions (communication, games, etc.) at no additional charge. The applet may also include a bar code which when displayed to a third party vendor, allows the user to receive a discount on purchases of goods or services related to the ad. In the best mode, the mobile platform includes a cellular transceiver adapted for a GSM or CDMA network. The mobile platform stores data relating to the output of the content and sends this data on command back to the server. The server includes code for forwarding this feedback data to advertisers.

A method for crediting a customer account maintained by a vendor of services in response to payment received from a customer is disclosed herein. The method includes issuing, to the customer, a membership account number associated with at least the customer account. A membership account number and a payment corresponding to a requested amount of a service offered by the vendor are received from the customer at a point-of-sale. The method further includes generating, at the point-of-sale, an authorization message including at least the membership account number and embedded transaction information identifying the service offered by the vendor and the requested amount. The embedded transaction information is then communicated from the point-of-sale to a database server. The customer account is credited, in response to the embedded transaction information, based upon an amount of the payment. The method also includes electronically transferring funds based upon the amount of the payment from a first account associated with the point-of-sale to a second account associated with the vendor.

The present invention comprises a system and method for providing a personal identification number (PIN) to a client terminal over a computer network. In accordance with one aspect of the present invention, a host connection manager receives a request for a PIN, which is associated with a particular monetary value. The host connection manager transmits the request for the PIN to a server, and the host connection manager receives the PIN from the server. In addition, the host connection manager is adapted to receive a client request indicative of the particular monetary value. The client request is generated at the client terminal and is transmitted from the client terminal to the host connection manager. In response to the client request, the host connection manager sends the PIN associated with the particular monetary value to the client terminal.

A method and system of restoring a functionality of a mobile user device. A lock screen is displayed on the display of the user device. An international mobile subscriber identity (IMSI) of a subscriber identity module (SIM) card presently installed in the user device is determined. The IMSI is sent to a Remote Recovery Server (RRS). A message is received from the RRS indicating whether the IMSI is authorized for the user device and whether an account of the user device is replenished at least in part. Upon determining that the IMSI is authorized for the user device and the account of the user device is replenished at least in part, at least one function that was previously restricted is restored.
