  • Publication number: 20120167179
    Abstract: Presented is a system and methods for allowing a user, through their end user device, to invoke and access on-demand and always-on time interval based multimedia priority services (MPS). The time interval can be specified by the user directly for the user's session or provided by a managing authority for a plurality of user sessions. The time interval can be specified as a period from user invocation forward or as a start time/date pair to an end time/date pair.

  • Patent number: 6999449
    Abstract: A system and method for monitoring and reporting a volume of data transferred between a Mobile Station (MS) and a data network during a data session. A Prepaid Server (PPS) maintains an MS account and informs a AAA Server of a predetermined volume of data that may be transferred during the session. A Packet Data Service Node (PDSN) sends interim accounting messages to the AAA Server which determines when the predetermined volume of data has been transferred, and notifies the PPS. When the account balance goes below a threshold volume, the data session is terminated. During handoff of the MS from a first PDSN to a second PDSN, a data tunnel is established between them. When the handoff is complete, the tunnel is torn down. The first PDSN reports the volume of data transferred through the tunnel to the second PDSN which reports the volume to the AAA Server.

  • Patent number: 6834300
    Abstract: A method in a Code Division Multiple Access (CDMA) 2000 packet data network of negotiating reporting mechanisms for accounting records, and sending accounting records from a Packet Data Service Node (PDSN) to an accounting server such as a Home Radius Server utilizing the Radius protocol. The PDSN sends an Access Request (AR) message to the accounting server, via any intermediate nodes, and includes (a) an Accounting Capability (AC) attribute indicating that the PDSN can accumulate a plurality of accounting records and send the accumulated accounting records in a container in a single message, and (b) an Accounting Handling (AH) attribute indicating a plurality of alternative reporting methods that trigger the PDSN to send a container. The Home Radius Server then sends an Access Accept (AA) message to the PDSN that (a) confirms that the Home Radius Server can receive accounting records in containers, and (b) indicates a preferred reporting method for triggering the PDSN to send a container.

  • Publication number: 20020167909
    Abstract: The present invention relates to a system, a method and a service node for providing a pre-paid service to a mobile station for data transmission in a packet data cellular telecommunication network. A connection is established between the mobile station and the service node in the packet data cellular telecommunication network. Upon establishment of the connection, at least one pre-paid connection limit parameter is obtained from a subscriber account database. The at least one pre-paid connection limit parameter is indicative of a limit at which the connection must be terminated. Then, the service node monitors the connection to determine whether the data transmission exceeds the at least one pre-paid connection limit parameter. If the data transmission exceeds the at least one pre-paid connection limit parameter, the connection is terminated.

  • Publication number: 20020116338
    Abstract: The invention relates to a solution for prepaid access to an Internet Protocol (IP) network, and particularly a third generation (3G) network. A user has a prepaid account configured in his terminal and in a Prepaid Server (PPS). When the user wants to access the network, an access server requests that the PPS authenticates the terminal and, if accepted, responds with a message informing the access server of how much the terminal can utilise network resources before a re-authentication is necessary. When this limit is met, the access server re-requests authentication until the user disconnects or the account is exhausted, in which case the user is denied further access.

  • Patent number: 6364066
    Abstract: An elevator rescue system provides rescue signals from a remote control station. The rescue signals typically operate a release mechanism such as the brake to allow the elevator to move to an appropriate door zone. The rescue signals are preferably sent from a remote control station such as may typically monitor a number of elevators. Essentially, the rescue signal is initiated when the remote control station receives a signal from the elevator monitoring system that a particular elevator is likely to have trapped passengers. As an initial step, the remote control station ensures there is no safety reason not to move the elevator, and then remotely commands operation of an elevator component that allows the elevator cab to move.
