摘要:
Methods (10, 70, 90, and 100) and systems (50, 80, 150, and 200) for enhancing user experiences on a mobile device use non-volatile execute-in-place memory (60, 160, 207) to provide faster boot-up, reduce current drain, improve security, and facilitate storage decisions that all enhance the operation of the mobile device for a user. Methods and systems embodied herein can include power management for handheld mobile electronic devices. Other embodiments are disclosed.
摘要:
A method and apparatus control message transmissions in an acknowledge-back selective call communication system (100) including an infrastructure (102) and a selective call receiver (120). The selective call receiver (120) stores received messages in a memory (322). The infrastructure (102) transmits (604) to the selective call receiver (120) information including the length (408) of a pending message, and the selective call receiver (120) determines (606) therefrom a response (412, 504) based upon the length (408) of the pending message and memory space available in the memory (322). The selective call receiver (120) transmits (608) the response (412, 504) to the infrastructure (102), and the infrastructure (102) controls further processing of the pending message in accordance with the response (412, 504).
摘要:
The present invention discloses a portable computing device (100) including a processor (102), alternate memory (106), and a DRAM memory (108). Under normal operating conditions, providing full functionality of the device, a full code instantiation in the DRAM is executed, providing operating system, user interface and application execution functionality. A reduced code instantiation (114) which duplicates certain elements of the operating system, user interface, and application code is maintained in the low power memory. When a condition occurs that dictates or allows, execution is switched from the full code instantiation to the reduced code instantiation, and the DRAM is shut off.
摘要:
A mobile communication device (102) includes a wide area network (WAN) modem (122) for communicating over a wireless WAN. During a voice call, the WAN modem operates in a power save mode (206) but must occasionally scan for handover candidate base stations (208). The modem goes directly from the power save mode to a scan mode at an agreed upon time, first selected by the mobile communication device, but which may be modified by the base station.
摘要:
A mobile communication device (102) contains both a WAN modem (122) and a PAN modem (134) which operate on interfering radio frequencies. To mitigate interference, and still permit real-time communication operation, the PAN is prevented from transmitting while the WAN is receiving (714). The PAN carries the real-time data via an active link (144) between the PAN modem and a remote device (142). The active link uses a retransmission protocol, which allows recovery of suppressed packets within a given period. The PAN modem is disabled for periods shorter than a maximum time which guarantees success transmission or retransmission of the PAN data. To further aid successful operation of the PAN retransmission operation, the WAN base station aggregates data into a single downlink burst.

Methods and systems for trusted boot using an original design manufacturer secure partition using execute-in-place non-volatile memory (XIP NVM) can include forming a secure partition within the XIP NVM and loading an initial program load within the secure partition wherein the initial program load comprises computer instructions which when executed by a processor causes the processor to perform operations comprising a trusted boot. Other embodiments are disclosed.
