Abstract: PROBLEM TO BE SOLVED: To provide a method of reselecting a mobile wireless communication device to a network subsystem before initiating a connection with a wireless communication network.SOLUTION: A connection request is received by the mobile wireless communication device in response to a user input (402). Attributes of signals received by the mobile wireless communication device from multiple network subsystems in the wireless communication network are measured over a period of time (403). The mobile wireless communication device is associated with one of the network subsystems and not associated with other network subsystems. The mobile wireless communication device reselects to one of the network subsystems based on quality metrics generated from the measured received signal attributes (404). After reselection, the mobile wireless communication device initiates a connection through the reselected network subsystem (405).

Abstract: A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

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: A method and apparatus for expanded cell search and selection in a mobile wireless device. The mobile device locates cells in a first of neighbor cells and in a second list of stored cells and evaluates located cells using suitability criteria. When locating a suitable first cell that uses a first radio access technology (RAT) in the first list, the first cell is selected. When locating a second suitable cell that uses a second RAT in the first list and not locating a suitable cell that uses the first RAT in the second list, the second cell is selected. When locating a third suitable cell that uses the second RAT in the first list and locating a fourth suitable cell that uses the first RAT in the second list, the fourth cell is selected when more suitable than the third cell.

Abstract: Offenbart wird ein Verfahren zur Reduzierung von Verbindungsabbrüchen in Szenarien mit Uplink-Leistungsbegrenzung. Das Verfahren kann ein drahtloses Datenübertragungsgerät beinhalten zur Ermittlung, dass sich das drahtlose Datenübertragungsgerät in einem Zustand der Uplink-Leistungsbegrenzung befindet, in dem eine Sendeleistung des drahtlosen Datenübertragungsgeräts auf eine Leistungsebene unterhalb des Leistungsklassenniveaus des drahtlosen Datenübertragungsgeräts beschränkt ist; Das Verfahren kann außerdem eine Downlink-Leistungsgrenze für die Sendung eines Messberichts beinhalten, um eine Verbindungsübergabe auf Grundlage des Zustands der Uplink-Leistungsbegrenzung auszulösen. Die Downlink-Leistungsgrenze kann über dem von einer bedienenden Basisstation konfigurierten Schwellenwert liegen. Das Verfahren kann zusätzlich beinhalten, dass auf Grundlage der gemessenen Downlink-Leistung ermittelt wird, dass die berechnete Downlink-Leistungsgrenze erreicht wurde, und dass ein Messbericht gesendet wird, welcher eine Verbindungsübergabe an die bedienende Basisstation als Reaktion auf die Erreichung der Leistungsgrenze für den Downlink auslöst.
