Abstract: A mobile device can save time by validating a stored message, which was previously unreadable, by utilizing a related message, which can be received at a much quicker rate. In accordance with some aspects, the mobile device can save time by validating the stored message by reading a new related message and subsequently re-reading or descrambling the stored message or its CRC. The first attempt to read the message might not be successful due to a scrambling information change or due to other reasons. The reason for the failure of the first attempt to read the message may be determined based on whether a later attempt to read the message with the same or a different scrambling information is successful.

Abstract: A reference signal management (RSM) program executing on a mobile device detects multiple reference signals, allocates those reference signals into groups, and performs reference signal management functions using information conveyed in the reference signals. The RSM program detects both broadband and narrowband reference signals and maintains updated groups of reference signals that are transmitted from access points with independent configurations or different radio technologies. Battery power of the mobile device is efficiently used to manage reference signals in heterogeneous network environments by preventing unnecessary handoffs, overhead downloads, access probes and new registrations. Reference signals are managed from both synchronous and asynchronous sectors and in idle mode as well as in connected state mode.

Abstract: A method of a mobile switching center includes determining if a message belongs to a first set of messages or a second set of messages, filtering the message when the message belongs to the first set of messages, and sending the message when the message belongs to the second set of messages. A method of an interworking solution includes receiving a message from an apparatus, determining if the message belongs to a first set of messages or a second set of messages, and discarding the message when the message belongs to the first set of messages. The first set of messages are 1× native messages unsupported for tunneling to a user equipment and the second set of messages are 1× native messages supported for tunneling to the user equipment for circuit switch fallback procedures.

Abstract: A method for correcting operation of the sleep oscillator (116) of a wireless communications device (100). Sleep oscillator frequency is estimated (412) so as to compensate for estimated temperature induced errors. In estimating temperature induced errors, errors (504) in sleep oscillator frequency are treated as being temperature induced errors (522), but probable multipath errors are bounded (410, 520) to predetermined sleep clock error maxima (602) corresponding to sleep duration over which the error occurred.
