  • Publication number: 20100184402
    Abstract: Communication networks and methods are disclosed for allowing a party (i.e., a controlling party) to monitor the usage of a handset in real time. The handset being monitored (i.e, a reporting handset) may be involved in one or more communication events, such as initiating or terminating voice calls, initiating or terminating data sessions, sending or receiving text messages, etc. When a communication event occurs involving the reporting handset, a communication event report is generated in the reporting handset or the communication network. The communication event report is then transmitted to a controlling handset of the controlling party so that the controlling party may view the report. Because the communication event report is generated and transmitted to the controlling party responsive to the occurrence of the communication event, the report of the communication event is provided to the controlling party in real time.

  • Publication number: 20100124318
    Abstract: IMS networks, text message systems, and methods are disclosed for delivering text messages to IMS wireline phones. A text message system of an IMS network receives a text message intended for the IMS wireline phone. The text message system identifies capability data for an IMS wireline phone that indicates the capability of the IMS wireline phone for handling text messages. The text message system processes the capability data for the IMS wireline phone to determine if the IMS wireline phone is capable of handling text messages. If the IMS wireline phone is not capable of handling text messages, then the text message system appends the text message to a caller ID header of an IMS signaling message, and forwards the IMS signaling message to the IMS wireline phone to display the text message on a caller ID unit associated with the IMS wireline phone.

  • Publication number: 20100042525
    Abstract: IMS networks and methods are disclosed for authorizing financial transactions. Credit card information, debit card information, and other purchasing data may be consolidated into an IMS device for conducting financial transactions, such as the purchasing of items from a merchant. Before a financial transaction can be completed, an IMS device transmits transaction data for the financial transaction to the IMS network. The IMS network then processes predefined purchasing rules to determine whether or not the financial transaction is authorized. If the financial transaction is authorized, then the IMS network transmits a confirmation message to the IMS device indicating that the financial transaction is authorized. If the financial transaction is not authorized, then the IMS network transmits a cancel message to the IMS device indicating that the financial transaction is not authorized.

  • Publication number: 20090268702
    Abstract: Communication networks and methods are disclosed that synchronize call feature data between an IMS network and a legacy network, such as a cellular network. An IMS subscriber server (e.g., a Home Subscriber Server (HSS)) is notified of changes to feature data for a call feature (e.g., call forwarding, call waiting, etc) in the IMS network. Responsive to the notification, the IMS subscriber server updates a legacy subscriber server (e.g., a Home Location Register (HLR)) in the legacy network based on the change to the feature data. Similarly, the IMS subscriber server identifies changes to feature data for a call feature in the legacy network. Responsive to the change, the IMS subscriber server notifies one or more application servers in the IMS network of the change to the feature data. Through the IMS subscriber server, feature data for call features is synchronized between the IMS network and the legacy network.

  • Publication number: 20090209229
    Abstract: Communication networks and methods are disclosed for providing offline charging in a 3GPP network for sessions over a wireless local area network (WLAN) access network. A AAA server in the 3GPP network provides offline charging messages for a session to an offline charging system. If a data flow is established during the session, such as streaming video, then a packet data network gateway provides offline charging messages for the data flow to the offline charging system. The AAA server and the packet data network gateway share charging identifiers so that one or both are able to include the charging identifier for the session and the charging identifier for the data flow in an offline charging message. This allows the offline charging system to effectively correlate CDRs for the session with CDRs for the data flow occurring during the session.

  • Publication number: 20090088129
    Abstract: Communication networks and methods are disclosed for sharing charging information between a home IMS network and a visited IMS network. If a signaling message for a session is received in the visited IMS network, the visited IMS network assigns a visited charging identifier (e.g., ICID), and shares the visited charging identifier with the home IMS network through signaling messages. Similarly, the home IMS network assigns a home charging identifier, and shares the home charging identifier with the visited IMS network through signaling messages. When CDRs are generated in the home IMS network and the visited IMS network, the networks include the home charging identifier and the visited charging identifier in the CDRs so that billing systems may more easily correlate the CDRs from the different IMS networks.

  • Publication number: 20080299971
    Abstract: IMS networks and methods are disclosed for providing supplemental content to a user of a communication device during registration. When a communication device attempts to register with an IMS network, the IMS network receives a register request message from the communication device, and processes the register request message to register the communication device. The IMS network also identifies supplemental content to provide to the communication device, such as account information, weather content, news, location information, advertisements, etc. The IMS network generates a register response message, and embeds or otherwise includes the supplemental content in the register response message. The IMS network then transmits the register response message to the communication device. Responsive to receiving the register response message, the communication device identifies the supplemental content in the register response message, and provides the supplemental content to the user.
