    Abstract: Methods and apparatus for power optimization in e.g. a wireless mobile device. In one embodiment the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g. the quality of the radio environment power considerations location etc. For example if a UE has not moved and its radio reception quality is good the UE is likely to successfully receive a paging notification (i.e. without multiple attempts). Consequently the UE configures itself to receive only a single paging indication.

    Abstract: APL1P721.AU A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to 5 associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least 10 one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria. \ \4 , : : S ta rt: Detect First Cell Fails Stored Suitability Criteria Search For And Locate A Set Of Candidate Cells Measure At Least One Signal Metric For Each Candidate Cell A Candidate Cell = First Cell?

    Abstract: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

    Abstract: A method for reducing power consumption in connected mode discontinuous reception is disclosed. The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission. The method can further include the wireless communication device determining a subset of remaining uplink transmission opportunities in the pending HARQ retransmission process to monitor for an uplink grant in response to receiving the ACK and monitoring the subset of remaining uplink transmission opportunities for an uplink grant. The method can additionally include the wireless communication device entering a sleep state for any uplink transmission opportunities remaining in the pending HARQ retransmission process after monitoring the subset of remaining uplink transmission opportunities in an instance in which an uplink grant for the pending HARQ retransmission process is not received for any of the subset of remaining uplink transmission opportunities.

    Abstract: Ein Jitter Buffer in einem Voice over LTE-Empfänger kann durch Funkpegel-Feedback (RLF) von sowohl lokalen als auch an anderen Orten liegenden Endpunkten beeinflusst werden, um die Jitter-Buffer-Verzögerung in Erwartung voraussichtlicher Verluste, die mit hoher Wahrscheinlichkeit eintreten werden, präventiv anzupassen. Die Funkereignisse des RLF und die Szenarien, welche die präventiven Anpassungen auslösen, können identifiziert werden, und ihre Verwendung kann anhand von mathematischen Formeln ausgedrückt werden. In Konzepten des Standes der Technik wird der momentane Jitter aus einem gewichteten Verlauf des Mediendatenstroms abgeleitet, und infolgedessen werden nur Pakete, die bereits angekommen sind, verwendet, um den momentanen Jitter zu berechnen, um die Länge des Puffers anzupassen. Durch Ausgeben und Nutzen von RLF sowohl von lokalen als auch von entfernten Endpunkten kann die voraussichtliche Verzögerung – für Pakete, die noch nicht angekommen sind –, verwendet werden, um den Puffer präventiv anzupassen, wodurch ein Paketverlust minimiert wird, ohne eine unnötige Verzögerung einzuführen.
