Abstract:
A method and apparatus for remote monitoring of daily dispensing of medication is disclosed. In one embodiment, a dispensing unit, equipped with a weight sensing mechanism, such as scale or balance, communicates with a monitoring application residing in a wireless terminal. The monitoring application provides supervision over a medication dispensing process.
Abstract:
This invention provides wireless safety network through the integration of mobile femto-cells (mFAP), into macro-cellular system. Such network provides safety management for students during their travel to and from school through the supervision of handovers between home and mobile femto-cell and the macro-cellular environment as well as supervision of class attendance, emergency function, and other services.
Abstract:
A method for acquiring time synchronization and location information with a Femtocell includes an access point base station conveying an activation request to a service provider through a wired connection, where the service provider provides wireless communication in a macro area, and where the access point base station provides wireless communication in a local area. The method also includes the access point base station performing a first plurality of procedures to acquire a time synchronization and a second plurality of procedures to acquire a location of the access point base station.
Abstract:
Automatic provisioning of an access point base station or femtocell. The method may include the femtocell transmitting first information (e.g., location information, signal measurement information, capability information, etc.) to a service provider (e.g., over an IP network). The femtocell may receive second information from the service provider, where the second information includes one or more operational parameters. The operational parameters may include hand-off parameters, admission policy parameters, PN or scrambling codes, power parameters, and/or other parameters. The femtocell may operate according to the received parameters to provide access for a plurality of access terminals in a local area.

Abstract:
A method and apparatus for communicating data signals using a spread spectrum cellular network, the cellular network including a plurality of base stations coupled to the cellular network the mobile unit assigned to one of the plurality of base stations. The method and apparatus receives a signal of another of the plurality of base stations (target base station) and determines the interference density to the target base station from the received signal.
Abstract:
A method of time division multiplexing for a forward data packet channel includes encoding parallel data sub-packets into parallel streams of turbo codes; interleaving each of the parallel streams of turbo codes to generate parallel streams of quasi-complementary turbo codes; modulating the parallel streams of quasi-complementary turbo codes to generate parallel streams of modulated data symbols; and multiplexing the parallel streams of modulated data symbols by one of multiplexing and non-complete puncturing to generate a single stream of modulation symbols.
Abstract:
A method and apparatus for enabling more efficient use of plural packet data control channels (PDCCHs) that are associated with a common block of one or more packet data channels in a cellular communication system capable of high-speed data communications. Mobile stations (MSs) within a coverage area of a base station (BS) are categorized in accordance with an expected ability to receive signal transmissions, by determining position, transmission path length, reported channel quality, required reverse transmit power, or otherwise. The plural PDCCHs are preferentially associated with different categories of MSs, and are transmitted at different levels of robustness. The most robust PDCCH reaches all served MSs, and another PDCCH is transmitted at a lower robustness for more efficient utilization. Power may be reduced, and/or data density increased, on a less robust PDCCH.
Abstract:
A method and apparatus for initiating a reverse link intergenerational handoff in a CDMA communication system that measures and compares parameters between a serving base station of one generation and a target base station of another generation to determine the best possible handoff initiation time instant for performing a reverse link intergenerational hard handoff. Different embodiments can utilize one of several procedures to determine the best possible handoff initiation time instant. A pilot signal strength embodiment determines a handoff initiation time instant based upon the total pilot signal strength of both a serving and target base station. An Eb/Nt embodiment determines a handoff initiation time instant based upon Eb/Nt (ratio of average power per bit to total received power spectral density) values of both a serving and a target base station. The method and apparatus decreases the probability of degraded or dropped calls during intergenerational handoffs.
Abstract:
A method of synchronizing measurement of a mobile station location with communications service includes performing communications service between the mobile station and a base station, transmitting a synchronization message from the mobile station to the base station to indicate that the mobile station will be unavailable for communications service during a selected time interval, measuring the mobile station location from the mobile station during the selected time interval, and resuming communications service between the mobile station and the base station.
