  • Patent number: 7486966
    Abstract: A communication system formed by a private network that includes a private wireless network. The communication system includes a public wireless network using a public wireless protocol, such as GSM, and includes public networks, such as PSTN, ISDN and the Internet, using a wired protocol, such as 1P. The private network also includes a local area network (LAN) and the private network connects to the public networks using a wired packet protocol, such as IP. The public and private wireless networks operate with the same public wireless protocol, such as GSM, and the private wireless network additionally operates with a wired packet protocol, such as IP. The communication system permits users to operate freely in both public and private wireless networks using standard mobile stations while achieving high private network data rates. The communication system uses normal wireless handsets or other mobile or fixed stations without need for any modifications.

  • Patent number: 7412257
    Abstract: Methods, systems, and computer program products for bridging mobile phone networks with other telephone networks. A telephone network comprises multiple individually addressable telephone lines connected to telephones and to a gateway, which in turn is connected to one or more mobile phones and potentially to one or more landlines. When the gateway receives an inbound call from one of the mobile phones, or an outbound call from one or the telephones, the gateway applies routing rules to determine how to route the call. Routing may depend on a variety of factors, such as time of day, cost, the mobile phone receiving an inbound call. To help identify the mobile phone as the source of an inbound call, a distinctive ring may be selected. To account for differences in the mobile phone network and the telephone network, the gateway translates signals between the two networks.

  • Patent number: 7406330
    Abstract: An IP PBX system that serves enterprise telephones via a landline IP network connection is be expanded to serve cellular wireless communication devices (WCD) via a cellular wireless carrier's radio access network (RAN). Calls to and from the cellular WCD are connected through the cellular carrier's RAN and the IP PBX system, so that the IP PBX system can control and manage the calls just as the IP PBX would control and manage calls involving other extensions on the IP PBX. A cellular WCD thereby becomes an IP PBX client station, i.e., an extension on the IP PBX system. As such, the cellular WCD can seamlessly benefit from many of the same IP PBX features that other more conventional IP PBX client stations (e.g., desk phones) enjoy.

  • Patent number: 7149542
    Abstract: A method and apparatus for connecting a subscriber apparatus or subscriber's network to a mobile network, wherein a network element is placed between a mobile network and a subscriber apparatus or subscriber's network. The network element emulates the appropriate interface towards both the mobile network and a subscriber apparatus or subscriber's network that are attached to the network element. The network element is assigned the task to switch and, if necessary, concentrate calls between the mobile network and subscriber's network. In addition, the network element advantageously comprises a database block that stores the subscriber data needed by the mobile network, which data correspond to subscriber apparatus in the subscriber's network connected to the mobile network.

  • Patent number: 7085560
    Abstract: A decentralized asynchronous wireless communication system is disclosed for providing the remote location retrieval of voice and data communication and allowing for flexibility of communication paths for local communication or for communication to external networks. The system makes use of external data communications modules that may communicate in a local mode, an extended mode, or a distant mode. The external data communications modules may also provide a communication path to a Public Switch Telephone Network and other communication medium. The entire system is monitored by a network of personal computers comprising an Artificial Intelligence (AI) Network to manage any catastrophic system failure. The entire system is suitable for operation in rural areas having a low population density and urban areas where hours of peak call loading could otherwise be detrimental to call completions.

  • Patent number: 7072630
    Abstract: A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access point in the communication system, and passing the RAB to a digital filter to produce a filtered RAB. In one embodiment, the reverse link data rate is determined based on the filtered value of the RAB. Furthermore, a processor in the access terminal may determine whether the access terminal is in an idle mode, and passing a non-busy state value of the RAB to the digital filter when the access terminal is in the idle mode. The filtered RAB may be compared to a threshold to determine a mode of reverse link data rate determination. The mode defines a set of criteria for an aggressiveness level of increasing or decreasing the reverse link communication data rate. The processor, therefore, determines the data rate based on the filtered reverse activity bit in accordance with the determined mode.

  • Patent number: 7072615
    Abstract: A method of inserting a communications module (6) into a wireless communication system (1) comprising at least one control module (2) and a plurality of communications modules (3, 4, 5) is disclosed. The system (1) is adapted to transmit messages either directly or indirectly between modules and each module is adapted to receive a wireless message and transmit a wireless message to a further communications module or to a control module. The communications module (6) is inserted into the system (1) and transmits a first signal in a set-up mode. If the first signal is detected by at least one pair of modules (2, 3, 4, 5), the communications module (6), by means of a signal from a control module (2), is installed to communicate directly with the two modules of at least one pair of modules.

  • Patent number: 7072659
    Abstract: A system for selectively answering a telephone from a remote location is disclosed herein. The system basically includes both a stationary unit and a portable unit. The stationary unit, first of all, is connectable in line with a telephone line extending to a telephone. The stationary unit includes a ring detector circuit for activating the system upon detecting a ringing signal received over the telephone line, a first antenna with transmitter-receiver, a switching circuit for seizing the telephone line, and an enclosure. The portable unit, on the other hand, may be carried on-person. The portable unit includes a second antenna with transmitter-receiver for establishing electromagnetic communication with the first antenna, an activatable switch for selectively triggering seizure of the telephone line in response to any ringing signal that is detected, a microphone for transmitting verbal communications over the telephone line whenever the telephone line is seized, and a casing.
