  • Patent number: 7369842
    Abstract: A mobile switching center is configured with software instructions which allow it to continue to provide at least limited call termination and call origination services for mobile terminals in the event of a failure of a signaling link between the mobile switching center and a home location register and/or a signal control point (SCP) in an intelligent network. For pre-paid callers originating or terminating a call, the mobile switching center marks a call detail record as indicating that the call is a post-paid call. The call detail record is later provided to the SCP after the signaling link has been restored in order to bill the mobile terminal. In one example, the signaling link between the mobile switching center and the home location register or SCP may be a satellite link, which may go down for various reasons such as for maintenances, an unexpected failure, or the orbit of the satellite goes outside the field of reception of an antenna in the signal path.

  • Patent number: 7369845
    Abstract: A portable communication device detects a current speed of travel of the portable communication device independent of any vehicle temporarily transporting the portable communication device. A speed based setting controller of the portable communication device compares the current speed to at least one threshold value set at the portable communication device. Responsive to the current speed exceeding the threshold value, the speed based setting controller automatically assigns a separate speed based setting to a current setting for each feature assigned to the threshold value, wherein each current setting for each feature designates the operability of that feature within the portable communication device, such that the current setting for each feature adjusts with a speed of travel as detected by the portable communication device.

  • Patent number: 7353030
    Abstract: A system and method for reducing power consumption and interference in a communications system that has multiple base radios. A base radio controller assigns priorities to the base radios in the system. When higher priority base radios have excess capacity, intracell handovers are used to consolidate communications from lower priority base radios to higher priority base radios. After transferring communications to higher priority base radios, the lower priority base radios can attenuate or shut off their transmitted signal in order to reduce or eliminate all the interference they cause other base stations in the system, and reduce transmission power requirements.

  • Patent number: 7317706
    Abstract: A method for scheduling messages transmitted on a forward common channel of a CDMA system. The method includes determining the ratio between the slotted and unslotted messages transmitted over the forward common channel over a period of time. For each time slot S(i) of the forward common channel, s % time is allocated from the duration of the time slot to slotted messages and u % time is allocated from the duration of the time slot to unslotted messages. The s % time and u % time are determined based on the ratio between the slotted and unslotted messages transmitted over the forward common channel over a period of time.

  • Patent number: 7308267
    Abstract: A call is routed to a wireless mobile station from a wireline network while bypassing a host mobile switching center (MSC) of the mobile station when the mobile station is registered at an MSC other than the host MSC. In particular, a service control point (SCP) in the wireline network receives a query from a tandem switch, associated with a trunk group of the host MSC, in response to an attempted termination of the call at the trunk group. Based on information from the query, the SCP retrieves registration data from a home location register of the host MSC, using IS-41 signaling. When the registration data indicates that the mobile station is registered at the alternate MSC, the SCP instructs the tandem switch to route the call directly to a trunk group of the alternate MSC, i.e., without passing through the host MSC.

  • Patent number: 7302255
    Abstract: A method for a WLAN access point to allocate telephone numbers for use by mobile stations. The access point includes stored data indicating one or more allowed telephone numbers. When a mobile station associated with the access point and acquires an IP address, the mobiles station sends a telephone number allocation-request to the access point, seeking allocation of a particular telephone number for use by the mobile station. If the telephone requested number is one of those allowed, then the access point associates the telephone number with the mobile station. On the other hand, if the requested telephone number is not one of those allowed, then the access point provides the mobile station with a list of the available telephone numbers, to allow a user to select a desired telephone number, and the mobile station may then send a new telephone number allocation-request, seeking allocation of the selected telephone number.

  • Patent number: 7299069
    Abstract: The present invention provides a method and an apparatus for adapting a communications network of a plurality of wireless access nodes, such as base stations to a changing environment. The method comprises determining a current location of at least a first user in the communications network, identifying a need for change in at least one parameter associated with a position of a first base station of the plurality of base stations based on the current location of the first user, and implementing a first response in the communications network in response to the need for change for the first base station. In this way, a self-deploying wireless access network may autonomously reposition base stations in a changing environment of user distributions across a coverage area and/or user demand by users of wireless communication devices, such as mobile units.

  • Patent number: 7295806
    Abstract: The principles of the present invention provide for using directional antennas to adaptively communicate in a wireless mesh network. A number of infrastructure components are included in a wireless mesh network environment. Each infrastructure component includes an omni-directional antenna and one or more directional antennas (e.g., electronically steered phased array antennas) that can be used to communicate with other infrastructure component and wireless devices. Directional antennas can utilize one or more directional beams that can be directed towards an infrastructure component or wireless device to communicate with the infrastructure component or wireless device. Infrastructure components can adapt to communicate with the same destination through different intermediary infrastructure components. Since the signal strength of a directional beam can be greater than that of an omni-directional antenna of the same gain, infrastructure components can be separated by greater distances.
