Abstract: 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 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 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.

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: A method of reselecting a mobile wireless communication device to a network subsystem before initiating a connection with a wireless communication network. A connection request is received by the mobile wireless communication device in response to a user input. 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. 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. After reselection, the mobile wireless communication device initiates a connection through the reselected network subsystem.

Abstract: Methods and apparatuses to select a transmit antenna in a mobile wireless device connected to a wireless network are described. The mobile wireless device monitors received signal characteristics through first and second antennas and switches antennas based on the monitored signal characteristics and on an assessment of the sufficiency of available transmit power headroom to accommodate data transmissions in the uplink direction. Sufficiency is determined based on one or more criteria including achievable data rate throughput, quality of service, grade of service, an amount of data buffered, an amount of resources allocated by the wireless network and a number of “power up” commands received by the mobile wireless device during a pre-determined time interval.

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.
