Abstract: A user while traveling may call an operator in an information/call center to request directions to a desired destination. In response, the operator obtains a directions file containing the requested directions. To facilitate the user receiving directions in installments in accordance with the invention, the directions file has an indicator associated therewith. The requested directions are read from the directions file to the user by an interactive voice response (IVR) unit via synthesized voice. The indicator is used to indicate in the file which direction is to be read to the user. The user may terminate the call after hearing a desired quantity of directions. When the user subsequently needs another installment of directions, the user may call back the IVR unit which then continues to read directions in the directions file from where the associated indicator indicates. The above process can be repeated, thereby enabling the user to controllably receive the directions in installments.

Abstract: A system for and method of providing Short Message Service (SMS) message notification to a cellular telephone customer regarding missed incoming calls that are missed while the cellular telephone is unavailable such as when the telephone is powered off. This is accomplished by generating a notification message at a SS7 gateway that includes caller ID/name ID information and/or time of the missed call. The message is preferably generated at the SS7 gateway only upon receipt of an “access denied” response with a reason code of at least one of MS Inactive, Busy, No Page Response or Unavailable that is sent from a home location register in response to a location request sent by the SS7 gateway. Once the generated message is complete it is sent to a message center where it is stored until it is retrieved by the cellular telephone soon after registration with the cellular network.

Abstract: An apparatus, method and system are provided for hand-off of a communication session from a serving base station to a target base station. The preferred system includes a switch coupled to the serving base station and to the target base station. Respective first and second terminals at the serving and target base station share the same directory number, with the first terminal of the serving base station providing the communication session with the mobile unit. For a hand-off, the target base station transmits a request designating the shared directory number to the switch. Upon reception of the request, the switch bridges the target base station, through a bridged call path, into the communication session, through a second terminal of the target base station having the shared directory number, to form a three-way communication session.

Abstract: A duplex radio transceiver, coupled to baseband circuitry and to an antenna, includes a receive chain, a transmit chain and a duplexer. The transmit chain includes filter components that attenuate signals originating from the transmit chain in a receive frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the receive band. Similarly, the receive chain includes filter components filter components that attenuate signals in a transmit frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the transmit band. A bias control circuit senses a power level associated with radio signals in the transmit chain and adjusts an amplifier in the receive chain responsive to the power level.

Abstract: A closed power control feedback loop system allows a single portable transceiver architecture to be used for systems in which a transmit signal including both a phase modulated (PM) component and an amplitude modulated (AM) component are supplied to a power amplifier and in systems in which the transmit signal has only a PM component supplied to a power amplifier. By injecting the inverse of the AM portion of the desired transmit signal into the closed power control feedback loop, the feedback loop will not cancel the AM portion of the signal, thus allowing a system where both a PM component and an AM component of the transmit signal are present at the output of the power amplifier to function using a closed power control feedback loop.

The resource proxy definitions are technology independent with respect to the communication mechanisms required to obtain the data. Resources are added to the resource proxy via a resource discovery mechanism automatically performed by the mobile device. Multiple network gateways can be defined and each is responsible for requesting and retrieving information for the resource proxy.

Abstract: Measuring wireless network performance from a remote site uses a mobile handset that may include an appropriate world wide network browser. A user connects the mobile handset to the remote site via the wireless network which is coupled to the world wide network. Once the connection is made, application software at the measurement site sends commands to the mobile handset and in response the mobile handset sends measurement data to the application software. The application software processes the data to provide information about the wireless network performance including analyses for predictive and diagnostic purposes, since measurement data from many handsets, many locations and many base stations at many times may be collected at one central location.
