摘要： Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA EvDO) include determining if a number associated with temporarily-disabled sectors of an available sector set of the multimode device while the device is operational with a 3G base station is at least equal to a threshold number. If the number is at least equal to the threshold number, a scan for a sector in the 4G network to handover the operation of the multimode device from the 3G base station associated with the 3G coverage to a 4G base station associated with the 4G coverage is initiated. A scan for a fixed period of time for a new available sector in the 3G network to be added in the available sector set may be initiated; and, if a new available sector is added to the sector set, it may be redetermined if the number associated with the temporarily-disabled sectors is at least equal to the threshold number, before initiating the scan for a sector in the 4G network.

摘要： Application requirements of an application running on a wireless device are received. The wireless device is handed off from a first network to a second network when a first handoff criteria is met based on the application requirements, first network conditions, and second network conditions. A second network usage of the application is limited based on the application requirements and the second network conditions, and first network conditions are monitored while the application is running on the wireless device in communication with the second network. The wireless device is handed off from the second network to the first network when a second handoff criteria is met based on the application requirements, the first network conditions and the second network conditions.
