Abstract: A method and mechanism for operating user equipment to enable efficient reselection from a first cell conforming to a first wireless standard to a second cell conforming to a second wireless standard. The second standard may require a higher transmission rate for packet-switched data than the first standard. While camping on the first cell, the user equipment makes measurements of received power from the second cell. A reselection timer is started when a measurement is detected that is sufficiently strong. In response to an access state transition to a non-active protocol state (such as UMTS-PCH), the UE saves the timer value. When data becomes available for transmission, an additional measurement is made on the second cell, and reselection to the second cell may be performed immediately if the additional measurement and the saved timer value pass one or more reselection criteria.
Abstract: A method, system and apparatus for providing better cellular network coverage and establishing a new cellular network technology infrastructure are provided. A representative apparatus is a communications device that includes a processing device, memory, a transceiver, and a miniature cellular tower unit. The memory includes a routing manager which has instructions that are executed by the processing device. The instructions include logics that facilitate making and receiving cellular network calls from and to the communications device. The transceiver transmits and receives radio frequency (RF) signals to and from a cellular tower and to and from at least one other communications device. The miniature cellular tower unit routes RF signals from the at least one other communications device to the cellular tower.
Abstract: Methods, devices, systems and computer program products are described for implementing on a communication device customized caller ID and remote functional management of a communication device via shared secret exchange between calling and called parties. Customized caller ID provides for a calling party to identify themself regardless of the device they are using to place to call. In addition, other remote functional management, such as call priority tagging, provides for the calling party to prioritize the call or otherwise customize a call ID message to the called party. By exchanging shared secrets amongst the calling and called parties, the customized caller ID method and remote functional management are secure, thereby eliminating the likelihood of unauthorized tampering by unknown parties. Shared secret exchange also provides for authorized callers to remotely access and manage the communication device, such as, for example, to remotely lock down or place the communication device in an off state.
Abstract: A base transceiver station receives first and second reception power values from a plurality of user equipments. The first reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station without using a reception beam formation function that allows a radio signal transmitted from a predetermined direction to be selectively received with increased reception sensitivity. The second reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station using the reception beam formation function. The base transceiver station selects, from among the plurality of user equipments, a user equipment to be handed over based on the first and second reception power values, and performs handover processing on the selected user equipment.

Abstract: A mobile station includes, where the mobile station supports a first frequency band and a second frequency band, an information element generating unit configured to generate an information element indicating at least one of whether a receiver sensitivity is degraded in the second frequency band, whether a certificate has been obtained for communications in the second frequency band, and whether transmission and reception bands of the mobile station correspond to a portion of a bandwidth of the second frequency band, and a transmitting unit configured to transmit the generated information element.
Abstract: A system and method which identifies locations associated with radio-frequency (RF) signal sources in an area, includes receiving multiple measurement sets from a plurality of collector devices. The collector devices obtain contemporaneous information on characteristics of the signal sources and absolute and/or relative location information of the collectors. These measurement sets are processed to discover positioning data for the RF signal sources that may be used to determine locations of devices in the area that are configured to receive or monitor the RF signals.

Abstract: A software upgrade application can be downloaded to a handset to selectively enable enhanced functionality physical layer circuitry. In a particular implementation, an OFDM handset or other portable modem includes selectively enabled time domain channel estimation circuitry. An upgrade application within the handset is activated. The handset is checked to confirm compatibility with the enhanced functionality and the upgrade application is checked to confirm its authenticity. The upgrade application then activates the enhanced functionality within the physical layer of the device.

Abstract: A base station apparatus, when performing the transmission controls of pico base stations, can perform an appropriate transmission control for each pico base station, while suppressing the increase of the amount of feedback information from a macro terminal to a macro base station and also suppressing the increase of the amount of transmission control information from the macro base station to the pico base station. In this apparatus, a transmission control unit (102) updates, on the basis of the control information, the priority level of each of a plurality of different correspondences in which the respective ones of transmission control guidelines are associated with the respective ones of a plurality of control information history patterns, and controls the transmissions on the basis of the control guidelines determined from the control information histories and the correspondences each having a respective higher priority level.

Abstract: After a user equipment (UE) in a communication network selects a serving cell for multimedia broadcast and multicast service (MBMS), the UE waits an average time before it can re-select a new MBMS serving cell. The average time is based on keeping track of average MCCH reading time, which varies among network operators. In other words, the UE uses time hysteresis but adapts the value of the time hysteresis to the way an operator has deployed its MBMS functionality.

A method as described herein includes identifying a signal sent by the mobile device and received by respective ones of a set of receivers including at least a first receiver and a second receiver, wherein the first receiver and second receiver are positioned collinearly to the target location; determining a first signal-quality metric observed at the first receiver and a second signal-quality metric observed at the second receiver with respect to the signal; computing a ratio associated with distances from the mobile device to the first receiver and the second receiver, respectively, based on the first signal-quality metric and the second signal-quality metric; and determining whether the mobile device is within a proximity region defined in relation to the target location based on the ratio.
Abstract: A method for delivering a mobile terminated call to a mobile device communicating with a mobile switching center (MSC) in one example comprises steps of attempting to deliver the mobile terminated call to a mobile device, receiving a message that the mobile device is no longer in the location area served by the visiting MSC and forwarding the mobile terminated call to a different visiting MSC. The mobile terminated call is forwarded directly from one VMSC to another VMSC without requiring two potentially international calls to be placed serially from the GMSC to a VMSC. This method of Mobile Termination Roaming Forwarding can reduce substantial delay in call setup while saving network resources during establishment of the first call.
