Abstract:
The present invention relates to the field of wireless communication and specifically the use of a cell-phone to monitor safe driving by suspending all communication to/from mobile terminal when the user of such terminal is an active driver, unless the vehicle is not a train and it is equipped with the hands-free functionality, or it is not in motion, or the active driver status has changed, or unless the user makes an emergency call.
Abstract:
A remote monitoring of the daily dispensing of prescription drugs by at-home care, an elderly or clinical trial patient is proposed. The system consists of a dispensing unit equipped with weight sensing mechanism such as scale or balance which communicates with the monitoring application residing in the wireless terminal, such as cellular phone over the Personal Area Network (PAN) wireless interfaces such as Bluetooth. The monitoring application provides supervision over the medication dispensing process as well as communication with unauthorized medical supervisor using wireless Wide Area Network (WAN) connection to the Internet.
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:
In a method and apparatus suitable to convey timely information for facilitating accurate reception of transmitted data, a pilot signal is modulated to convey information. The information may facilitate efficient interpretation of an associated traffic signal. Modulation of a pilot signal frame may be limited to ensure early detection, and/or to minimize impairment of pilot functionality. In one embodiment, a Secondary Pilot Channel (SPICH) is transmitted at one of several selectable power levels to boost effectiveness of a phase reference, and is modulated to indicate the selected level. Such timely information enables prompt optimal combining of the SPICH with a primary Pilot Channel (PICH), and/or permits processing efficiencies for an associated traffic channel. Pilot signal frames may be transmitted at a predetermined level during a detection preamble portion of a frame to ensure accurate and early detection, and at a more optimal level thereafter.
Abstract:
A method and apparatus managing a list of base stations (“BSs”) for which a mobile station (“MS”) can establish an optimal communications channel are disclosed. In accordance with the teachings disclosed herein, a MS acquires suitable parameter information (“information”) and bases a subsequent switching decision based upon such information. Suitable parameters comprise cell loading and/or service priority, and MS needs. Such information comprises, for example, a number of BS users, switching latency associated with a particular BS, applications available by a BS, available code space, and a number of MSs for which a particular BS can provide resources. A MS decision to switch from a first BS to a second BS is predicated upon the acquired information.
Abstract:
A method, apparatus, and system permits an access terminal (“AT”) for a multi-carrier CDMA wireless communication system to concurrently receive data on N different-frequency carriers while restricting one or more parameters that affect data reception rate, so that limited resources of the AT will be sufficient to properly process data packets on the N carriers. The data rate controlling parameter may be “I,” the number of supported H-ARQ channels for one or more of the N carriers. A relationship may be defined between the number of supported forward and/or reverse link carriers, versus the number of supported H-ARQ channels and/or other data rate controlling parameters. Messages may enable identification of AT characteristics, and configuration and/or dynamic re-configuration of AT data communication capabilities that are related to different values of N and corresponding different data rate controlling parameters.
Abstract:
A method and apparatus for reducing power dissipation in mobile stations that are configured to provide concurrent voice and high-speed packet data communication capability in a cellular telecommunications system. A state is defined during which data directed to a mobile station (MS) is not fully receive processed by the MS. Such a reduced receive processing state may be co-extensive with a Control Hold state. A notification mechanism is presented by which a serving base station directs a mobile station to return from reduced to full receive processing in advance of transmitting data on a packet data channel. The notification may take several forms, such as a message presenting the MS MAC address and one or more other bits of predetermined data content. Return to active (full receive) status may be required to be completed within a predetermined time, such as one ACK delay, after notification.
Abstract:
A method to enable scheduling communications activities for an electronic communication device configured to communicate across a communication network is provided. The method comprises the steps of scheduling a communication activity during a scheduling window such that the communication activity is scheduled to occur toward the end of a communication window; entering a power-save mode after the scheduling step; and transitioning from the power-save mode prior to the scheduled communication activity. In one embodiment the method can further include a step of conducting the scheduled communication activity and transitioning back to the power-save mode after a next communication activity is scheduled or be implemented to allow the step of conducting the scheduled communication activity and transitioning back to the power-save mode at the end of the next communication window. In one embodiment the transitioning step comprises the steps of awakening from the power-save mode and synchronizing with the communication network, wherein synchronizing can comprise the step of synchronizing with electronic communication device associated with the communication network.
Abstract:
A novel method and apparatus for performing cell selection handoffs in a wireless communication system is disclosed. The CSHO method and apparatus of the present invention determines which transmitters to temporarily disable or “gate off” during soft handoff procedures. The method and apparatus of the present invention monitors the channel conditions for all base stations in an active set of a selected mobile station and determines the relative strengths of base stations based on the monitored channel conditions. The method and apparatus of the present invention reduces interference to receivers in a wireless communication system. Specifically, the present invention temporarily disables, or “gates off” selected transmitters (e.g., base stations) during soft handoff procedures and thereby reduces interference to receivers that are not associated with the selected transmitters. Reducing this interference increases the overall voice and data capacity in a wireless communication system.
