  • 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: 6917612
    Abstract: A system and unified method of address resolution in an IP-based network. A Resolver determines whether an input address is a URL/URI, and if so, extracts a domain name. If the input address is an E.164 number, the Resolver converts the E.164 number into a domain name in ENUM format. The Resolver then sends a domain name query to a DNS which, if able, returns the IP address for either a Global MGCF or a destination server along with a supported Application protocol. If the DNS is unable to perform the translation, or the Application protocol returned is not supported by the requesting application, the Resolver sends a domain name query to an extended Location Server (LS) to obtain an IP address of a gateway function capable of interfacing with the destination server.

  • Patent number: 6912214
    Abstract: A system and method for optimizing the use of packet-resources by releasing a hanging packet-data connection when a Mobile Station (MS) performs a power-down while involved in a dormant packet-data session. A Base Station Controller (BSC) sends a message to a Mobile Switching Center (MSC) indicating that the MS has powered down. The MSC determines that the packet-data session is dormant, and sends an instruction to the BSC in a class-0 connectionless transaction to release network resources associated with the packet-data session. The BSC then sends an instruction to a Packet Control Function (PCF) to tear down the associated resources, and the packet-data connection is released by a Packet Data Service Node (PDSN) in response to the tearing down of the resources by the PCF.

  • Patent number: 6834044
    Abstract: A system and method in a packet-switched radio access network of sending data packets over a radio interface from a Mobile Station (MS) to a Radio Network Controller (RNC) using multiple data transmission paths. When the MS launches a new application through a first base station (BS1), a Multi-path Context Activator (MCA) in the RNC determines whether the bandwidth required by the new application exceeds the bandwidth capacity of the radio interface portion of the first data transmission path. If so, the RNC identifies a second BS (BS2) that has the capacity to provide a portion of the radio interface bandwidth required. The MS then transmits separate data streams to BS1 and BS2 as over the radio interface. The MCA combines the separate upstream data portions. For downstream packets, the MCA separates the packets into two streams which are sent to an MCA in the MS via BS1 and BS2.

  • Patent number: 6785246
    Abstract: A system and method for setting up a multi-party conference call in a packet-switched radio telecommunications network in which a Gatekeeper (GK) has established an on-going two-party call between a first party and a second party. The first party sends an enhanced Facility message to the GK that indicates a multi-party conference call is desired, and includes a globally unique conference identity and a list of telephone numbers for third parties to be joined. A Multipoint Controller (MC) provides an Internet Protocol (IP) address of a Multipoint Processor (MP) to each of the parties, and provides the IP addresses of the parties to the MP. The MC then negotiates media sessions with each of the parties, and sends the negotiation results to the MP. Each of the parties then sends its media payload to the MP where the payloads are mixed and forwarded to the other parties.

  • Patent number: 6424832
    Abstract: A method of supporting functionality for roamer port calls in a radio telecommunications network in which Number Portability (NP) is implemented, the network having a plurality of mobile switching centers (MSCs) and home location registers (HLRs). The network includes a roamer port MSC having a roamer port which is shared with at least one neighboring MSC. A number portability database (NPDB) associates a location routing number (LRN) with each distinct MSC/HLR pair in the network. When a roamer port call, which includes the mobile directory number (MDN) of the called mobile station, is received in the roamer port MSC, the roamer port MSC determines whether the MDN falls within a ported range. If so, a request is sent to the NPDB to retrieve a LRN for the called mobile station. From the LRN, a HLR associated with the mobile station is identified.

  • Patent number: 6397056
    Abstract: A system and method of reducing control message signaling load in a radio telecommunications network. When an authentication request is issued by the mobile switching center (MSC), the home network performs authentication of the visiting subscriber. When authentication fails the home network determines if a threshold value is reached. If so, a suitable authentication code portion is included in the return message so that local authentication of the visiting subscriber may be performed. The MSC is able to locally authenticate a visiting subscriber trying to access the network thereby suppressing the transmission of additional authentication requests and failure reports to the home network. For failed authentications, the VLR transmits authentication failure reports to the home network. If a threshold value is reached the MSC locally authenticates the mobile subscriber's subsequent attempts so that the VLR is precluded from sending additional authentication failure reports to the home network.

  • Patent number: 6389039
    Abstract: A system and method of transferring data to and from a mobile station (MS) in a cellular telecommunications network. When the MS originates a data transmission, the MS simultaneously seizes additional voice channels or control channels from the serving cell or adjacent cells, fills time slots with data packets, and asynchronously transmits the data packets over the plurality of channels in order to increase the data transfer rate. For data calls terminating at the MS, the serving mobile switching center (MSC) reserves a plurality of channels having sufficient signal strength to maintain a connection with the destination MS. The MSC informs the involved base stations that an asynchronous transmission is to be made to the MS. The MSC then assembles the data packets and starts transmission through the involved base stations to the MS over the reserved channels. The MS assembles the packets in numerical order and delevers the data to the user.
