20130083784 | METHOD AND APPARATUS FOR PROVIDING SERVICE - A method and apparatus for providing a service in a service providing device are provided. The method includes receiving, from a terminal, information about a wireless transmitter/receiver whose vicinity the terminal is located within; determining a differentiated service to be provided to the terminal according to the received information about the wireless transmitter/receiver; and providing the determined differentiated service to the terminal. | 2013-04-04 |
20130083785 | SYSTEM AND METHOD FOR PROVISIONING TELECOMMUNICATIONS SERVICES BETWEEN AN ACCESS POINT AND A TELECOMMUNICATIONS NETWORK AND PROVIDING MISSING INFORMATION NOTIFICATION - A method and system for selectively provisioning connections between an access point, which supports telecommunications services over an IP network, and a carrier network includes a network connection and a telephone connector suitable for connecting to a landline telephone, a cordless telephone, or a mobile device. The access point sends a provisioning request, which includes identifying information such as a subscriber identifier and a MAC address, to a network controller. The network controller attempts to find a geographic, street, or other address associated with the connection to be provisioned. If an address is not found, the network controller rejects the connection and sends a missing information notification to the access point. After receiving the missing information notification, the access point controls a user indicator to provide error information. | 2013-04-04 |
20130083786 | METHOD AND APPARATUS FOR SYNCHRONIZATION IN A DYNAMIC SPECTRUM ACCESS (DSA) COGNITIVE RADIO SYSTEM - A method and apparatus for synchronization in a dynamic spectrum access system is provided herein. During operation a transmitter will vary a known sequence to generate a preamble for each radio frame. The variation of the known sequence is based on what particular subcarriers are currently being used by the transmitter. In one embodiment, the preamble is coupled to the filterbank multicarrier synthesis to generate an over-the-air preamble for use in synchronizing a receiver. | 2013-04-04 |
20130083787 | CONFIGURATION OF A NEAR-FIELD COMMUNICATION ROUTER ACCORDING TO THE MODULATION TYPE - A method for configuring a first near-field communication device according to a modulation type transmitted by a second device, wherein: a decoder of the first device is configured to decode a type-A modulation; a signal received during a first time slot corresponding to the duration of a first type-A symbol is decoded; and the first device is configured according to the value of the decoded symbol to determine the modulation type. | 2013-04-04 |
20130083788 | Delay-Induced Scattering with Phase Randomization and Partitioned Frequency Hopping - A method includes generating multiple copies of a signal that comprises a plurality of time division multiple access frames. The multiple copies of the signal includes a first copy and one or more other copies of the signal. Each of the one or more other copies of the signal having a respective fixed delay and a respective phase relative to the first copy of the signal. The method also includes transmitting the multiple copies of the signal using hopping carrier frequencies. The hopping carrier frequencies associated with a consecutive pair of the plurality of time division multiple access frames are separated by an odd multiple of a separation value representing a frequency separation between two adjacent carrier signals. The respective fixed delay is proportional to the separation value for each of the one or more other copies of the signal. | 2013-04-04 |
20130083789 | Clock Synchronization and Distributed Guard Time Provisioning - Embodiments provide a method to accommodate clock drift and guard time in a distributed fashion. A first device is adapted to communicate with a second device. A clock in the first device is synchronized to a clock in the second device using beacon or/and acknowledgement frames from the second device. A nominal guard time is computed that accounts for clock drift in the first and second devices during a nominal synchronization interval. An additional guard time is computed that accounts for clock drift in the first and second devices during an additional interval beyond the nominal synchronization interval. An available transmission interval is determined within an allocation interval for transmissions between the devices, wherein the beginning and/or the end of the available transmission interval are selected by accounting for the nominal guard time and/or the additional guard time. One or more frames are transmitted within the available transmission interval. | 2013-04-04 |
