  • Patent number: 7130626
    Abstract: Access terminal identification management providing a minimum distance between subnets before reusing subnet identifiers. Mobility criteria evaluation determines when to reassign an access terminal identifier. In one embodiment, the mobility criteria is whether any member of the active set for the access terminal belongs to an originating subnet. In an alternate embodiment, the criteria is whether the access terminal has traveled more than a minimum distance from the originating subnet. When a mobility criteria is violated, the access network assigns a new identifier. In one embodiment, the access terminal identifier is a long code mask based on a subnet identifier. Identifier management applies when crossing sector boundaries in a cellular system, and serves to reduce the ambiguity of mapping CC values to full UATI values, and to avoid overlapping assignments.

  • Patent number: 7127654
    Abstract: A method and an apparatus for quick retransmission of signals in a communication system are disclosed. A transmitting terminal, e.g., a base station, transmits signals in a form of packets to a receiving terminal, e.g., a subscriber station. The receiving terminal determines if the packet was intended for the receiving terminal, and if so, the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics match, the packet is declared correctly received, and is forwarded for further processing. If the quality metrics fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. The transmitting terminal then schedules the packet for retransmission.

  • Patent number: 7113766
    Abstract: Systems and methods consistent with the present invention provide a transaction processing during which a transaction billing event is created. Metadata associated with an application is stored in a transaction manager database. When a wireless device downloads an application, raw transaction information is sent to and stored in the database. The raw transaction data may include a subset of the metadata and additional information included by other devices and/or systems. Billing events are created by correlating the metadata and the raw transaction data. In addition, subscription billing events, such as those having reoccurring charges, are calculated by evaluating those transactions having a subscription transaction type and their associated metadata stored in the database.

  • Patent number: 7106782
    Abstract: Techniques to adjust the phase rotation of a modulated signal to compensate for the phase rotation introduced by circuit elements associated with the transmit signal path. In one implementation, at least one control signal is received, with each control signal being provided to adjust a particular characteristic (e.g., gain, bias current) of one or more circuit elements (e.g., VGA, PA) associated with the transmit signal path. The circuit elements can be located directly in, or operatively coupled to, the transmit signal path. A phase rotation corresponding to an operating state defined by the received control signal(s) is then determined, and the phase of the modulated signal is rotated by an amount related to the determined phase rotation. The phase rotation compensation can be performed at various locations along the transmit signal path by rotating either the data, the PN sequences used to spectrally spread the data, or the carrier signals used to modulate the data.
