Abstract: Methods, systems and devices are providing for managing quad SIM functionality on a mobile device. The method includes maintaining active in a data traffic state on a first radio frequency (RF) chain of the mobile device a first subscription of a first SIM. Also, maintaining active in a slotted idle state each of a second SIM subscription, a third SIM subscription and a fourth SIM subscription on a second RF chain of the mobile device. The slotted idle states enabling the subscriptions to monitor pages in their paging channel slots. The method may include switching the third and fourth subscriptions to the first RF chain in response to the second subscription exiting the slotted idle state. The first, subscription may operate with tune away support while the third and fourth subscriptions operate in slotted idle state together on the first RF chain.

Abstract: A method for channel scanning includes: accessing a communication network with a first subscription on a first band and channel combination using a first pseudorandom noise (PN) code; determining if channel quality on the first band and channel combination using the first PN code has deteriorated; in response to determining that the channel quality has deteriorated, determining if a good sector is available on the first band and channel combination; in response to determining that a good sector is available, preventing the first band and channel combination from being placed on an avoidance list; and handing off to the good sector using a second PN code.

Abstract: Systems, methods and apparatus for optimizing machine-to-machine device performance are provided. In one aspect, a method comprises acquiring a pilot signal and determining a clock drift of the device based on the acquired pilot signal. The method further comprises selectively adjusting the frequency with which the device reacquires the pilot signal based at least in part on the determined clock drift. The slot cycle index is reduced when the determined clock drift is greater than a first predetermined fraction of a reacquisition window size. The slot cycle index is reduced when an anticipated clock drift of the device is greater than a second predetermined fraction of a reacquisition window size and the device fails to reacquire the pilot signal, the device is handed off, a finger energy is less than a first predetermined threshold, or a channel estimate value is less than a second predetermined threshold.
