20120170569 | ADAPTIVE TIMERS FOR POLLING IN A MOBILE WIRELESS DEVICE - A method for adapting data retrieval polling in a mobile wireless device. The mobile wireless device is configured in an adaptive pull mode and polls a remote server when a data retrieval polling timer expires. Data retrieval information is stored in the mobile wireless device and the data retrieval polling timer is updated to a value based on the stored data retrieval information. The data retrieval information includes time intervals between successive polls or time delay intervals between data arrival at and retrieval from the remote server. Updates are based on weighted moving averages of the data retrieval information. | 07-05-2012 |
20130295997 | DEVICE INITIATED CARD PROVISIONING VIA BEARER INDEPENDENT PROTOCOL - A processor in a mobile wireless device provisions a user identity module (UIM) card in the mobile wireless device in response to a user command. The processor detects a user command to provision the UIM card and reads a provisioning status of the UIM card from a UIM card provisioning status file in the UIM card. When the provisioning status is “not provisioned”, the processor establishes a bearer independent protocol (BIP) data connection to a server in a wireless network and exchanges provisioning data between the server and the UIM card until the UIM card commands the processor to close the BIP data connection. In representative embodiments, the UIM card provisioning status file includes fields for a UIM card provisioning status, a UIM card software version and a UIM card provisioning date/time, and the processor updates the fields during provisioning. | 11-07-2013 |
20140051449 | METHODS AND APPARATUS FOR RADIO LINK IMBALANCE COMPENSATION - Methods, apparatuses and computer readable media are described to compensate for radio frequency link imbalances in a wireless communication device. Processing circuitry in the wireless communication device detects a radio frequency link imbalance for a bi-directional communication link. The wireless communication device biases one or more operational parameters of the wireless communication device to adjust for a performance degradation induced by the radio frequency link imbalance. The wireless communication device determines whether a trigger condition for cell selection, reselection, or handover occurs based on the biased operational parameters, and when the trigger condition occurs, performs a remediating action to compensate for the radio frequency link imbalance. Remediation can include performing an intra-RAT or inter-RAT reselection or handover. | 02-20-2014 |
