Abstract: A stationary access terminal, such as a stationary remote sensor, capable of wireless communication with a network is provided. The access terminal obtains sector information associated with a wireless network node by establishing a communication link with the network node. The access terminal then stores the sector information in non-volatile memory, and later retrieves the sector information from the memory, for example, after a subsequent boot up or wake up event. The stored sector information is used by the access terminal to establish a subsequent communication link with the network node, and may include at least one of channel, band, and pseudo-random number sequence information. The access terminal may also store overhead messages received from the network node in the non-volatile memory. The stored overhead messages may later be retrieved to establish system operating parameters of the network node after the subsequent boot up or wake up event.

Abstract: An access terminal configured for use in a wireless communication system utilizing discontinuous reception (DRx). To reduce power consumption, a pilot acquisition timeline may be reduced when channel conditions are favorable; and to improve call quality, the pilot acquisition timeline may be increased when channel conditions are poor. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.

Abstract: Access terminals are adapted to facilitate power conservation by selectively powering down one or more hardware block when processing a general page message (GPM) received in slotted idle mode. An access terminal may include a processor core, a de-interleaver, a decoder and a firmware block. The firmware block may be adapted to enable the processor core to sleep while the firmware block collects samples of a received transmission and extracts symbols from the collected samples. The firmware block may further power ON the de-interleaver to de-interleave the extracted symbols, and the decoder to decode the de-interleaved symbols. Other aspects, embodiments, and features are also included.

Abstract: Various features and aspects of the present disclosure are adapted to facilitate improved reception of page messages at an access terminal operable in a wireless communication system. When the access terminal is in a region where two or more cells overlap, if the access terminal is moving away from the coverage area of an active cell and moving towards the coverage area of a neighbor cell, the access terminal may miss an incoming page message transmitted from its serving cell. Thus, the access terminal may dedicate fingers of a rake receiver to listen to paging information transmitted from one or more neighbor cells, decoding this information if a page decoding operation corresponding to the active cell fails. Other aspects, embodiments, and features are also claimed and described.

In one aspect, a mobile device is operated in slotted mode. The mobile device wakes up to perform a pilot reacquisition corresponding to a slotted mode and detects a slew of a pilot timing relative to a pilot reference timing. The mobile device adjusts a subsequent pilot reference timing by an amount corresponding to the detected slew, to be utilized during a subsequent wake-up cycle. The mobile device returns to a sleep state to wait for the subsequent wake-up cycle. Other aspects, embodiments, and features are also claimed and described.

Abstract: Performance is improved in certain M2M devices by suppressing explicit network registration or attachment. The described techniques may be used, for example, by M2M devices that periodically or occasionally transmit event data using wireless communication networks without needing to receive periodic or on-demand communications from the network for regular operation. In some embodiments, an M2M device may continue to monitor pilot channels of available wireless networks, select a particular network for communication from among the available wireless networks, and monitor system information for the selected network without registering on the selected network. The M2M device may suppress explicit registration based on one or more explicit registration triggers associated with the selected network. The M2M device may be implicitly registered as part of the network access transmitting the captured or measured event data to the selected network.

Abstract: Aspects of the present disclosure provide methods and apparatuses for improved throughput for network subscriptions in multi-SIM, multi-standby wireless devices by altering a tune away frequency to another network subscription based on throughput level or communication link parameters. For example, the present application provides a method of tune away in a wireless system, which includes initiating a data session via a first subscription in a multi-subscriber identity module, multi-standby user equipment, determining that a data rate associated with the data session is less than a threshold data rate value, establishing a modified tune away frequency based on the determining, and tuning a radio resource away to a second subscription based on the modified tune away frequency. Through such operation, throughput on an active subscription in such user equipment can be dynamically maximized.
