  • Patent number: 8094613
    Abstract: A method of assigning calls to a hot cell site. A hot cell site is a cell site for carrying highly concentrated traffic, which cell site supports only a proper sub-set of the frequencies supported by other (basic) cells. It is surrounded by hot zones of other (basic) cell sites. When mobile stations enter the hot zone, an extra percentage of powered-on, but idle mobile stations is tuned or re-tuned to one of the frequencies supported by the hot cell. Advantageously, this increases the traffic carried by the hot cell. In accordance with one feature of the invention, if a hot cell is approaching the limit of its call carrying capacity, it will hand-off calls to a neighboring cell. Advantageously, the hot cell usage is optimized.

  • Patent number: 8090346
    Abstract: This invention relates to a feature for controlling resellers of telecommunications services. A service provider may freeze the accounts, and therefore service, for all customers of a reseller if that reseller is behind on payments to the service provider. In one preferred embodiment, all customers of a reseller are identified with a reseller identification field in the customer's data stored by the service provider. When the service provider issues a freeze order, the account records for all customers of the reseller, identified by the reseller identification stored for each customer, are set into a frozen state wherein these customers cannot initiate or receive calls; after the frozen state is removed, the various promotions allotted to each customer are reinstated. Advantageously, the threat of freezing service to the customers of the reseller is a potent weapon to force the reseller to pay the service provider.

  • Patent number: 6539004
    Abstract: Methods and apparatus for transmitting packets from a source of such packets to one or more radio station sites so that the radio station sites can transmit the packets at the correct real time. Each radio site has an independent source of exact time based on the reception of signals derived from satellite inputs. Using the real time calculated by a base station, the base station calculates an offset between the time of arrival of a signal with a specified time marker, and the time that a signal with that specified time marker should have arrived in order to be transmitted in a timely fashion. The offset is sent back to the source of packets, and used by the source of packets to advance, or retard, the transmission of future packets. Advantageously, packets can be transmitted from each base station at the correct time, and if packets are being transmitted for a given call from several base stations, can be transmitted simultaneously, by these base stations.

  • Patent number: 6539090
    Abstract: Apparatus and a method for controlling the establishment of telecommunications calls. In response to a service request from a calling party, a switch serving the calling party transmits a query identifying the called party to a shared database. The database provides information identifying the switch for accessing the called party, and information for identifying port(s) for accessing the called party from that switch. When a customer moves from one location to another, the database is updated to reflect the switch and port identification associated with the new location of the customer. If the called customer is a mobile customer, the database maintains information concerning the current location of that customer so that calls can be immediately switched to that customer.

  • Patent number: 6532231
    Abstract: An arrangement and method for switching a single destination data channel to a different destination without losing any data messages. Such a switch is required, for example, when a switch is made to a standby control unit and the messages originally destined for the original active control unit must be sent to the standby. Received messages are drained from the source prior to making the switch. Appropriate data is copied from the active unit to the standby so that the standby unit is in a state to start accepting newly queued messages from the source.

  • Patent number: 6493445
    Abstract: This invention relates to methods and apparatus for handling incoming or intra-office calls when a telephone subscriber having a POTS, (Plain Old Telephone Service) telephone instrument and line connecting that customer to a serving switch, is connected to an Internet service provider for providing communications to the Internet. The bandwidth of the customer's line is divided into a lower band for providing communications, and a higher band for transmitting signaling and control information. When an incoming or intra-office call is received while the customer is connected to the Internet, the signal channel is used to transmit information which can be displayed to the called customer providing information about the call. If the called customer wishes to answer the call, the called customer can signal over the signaling channel a request that the incoming or intra-office call be completed.

  • Patent number: 6493549
    Abstract: An improved method of updating parameters stored in memory of mobile telecommunications stations. An object model represents all the parameters that can be modified in an IS-683A mobile station. The details of the physical location of each parameter are defined in this mobile object model. Advantageously, when any parameter is changed or added, it is necessary to provide the computer system, which generates messages to be transmitted to the mobile station, only the identification and value of the parameter to be added or changed. The computer system then generates a message sequence that defines the memory location in the mobile station to be changed, and the new value of the data for that memory location. Advantageously, this arrangement sharply reduces the total number of airwave messages transmitted to the mobile station in order to change or add a parameter.

  • Patent number: 6452490
    Abstract: A method and apparatus for communicating between Customer Premises Equipment, (CPE) alarm sensing devices, and alarm monitoring stations. The sensing devices communicate with an end office switch by transmitting a message, such as a string of Dual-Tone Multi-Frequency, (DTMF) digits to that switch. At the switch, the message is processed and a determination is made which of a plurality of alarm monitoring stations should receive the alarm indication. One or more data packets are sent to the selected alarm monitoring stations with the packets identifying the source of the alarm indication, and the type of alarm indication. Advantageously, the packetized communication between the end office switch and the alarm monitoring system allows a high volume of alarm indications to be sent to an alarm monitoring station, because individual telephone connections are not required for each such alarm message.
