20090109896 | SESSION ESTABLISHMENT IN MULTI-CARRIER DATA TRANSMISSION SYSTEMS - An access terminal acquires a multi-carrier radio network on an acquisition channel, receives a list of available channels from the network, and hashes to a channel on which the access terminal attempts to establish a session. If the access terminal fails to establish the session, the access terminal selects a new acquisition channel from an acquisition table other than the acquisition table from which the original acquisition channel was selected. The access terminal then repeats the above steps in order to attempt to establish a session, beginning with acquisition on the new acquisition channel. In this way, the number of unsuccessful session establishment attempts resulting from back end network failures is typically reduced, shortening the time to successful session establishment, reducing power consumption by the access terminal, and lessening interference due to unsuccessful attempts to establish a session. | 04-30-2009 |
20130040671 | ANTENNA TO TRANSCEIVER MAPPING OF A MULTIMODE WIRELESS DEVICE - Various arrangements for mapping antennas to transceivers are presented. A plurality of antennas may be present. Each antenna of the plurality of antennas may be configured to communicate using different radio technologies. A plurality of transceivers may be present. At least some of the transceivers of the plurality of transceivers may be configured to utilize different radio technologies. A selector circuit may be present that is configured, based on input from a processor, to map each antenna of the plurality of antennas with each transceiver of the plurality of transceivers. The processor may be configured to control which antennas of the plurality of antennas are mapped to which transceiver of the plurality of transceivers. Touch sensors may be used to determine which antenna or antennas are likely to serve as effective electromagnetic transducers. Signal-to-noise measurements may be used to determine when to modify an antenna mapping. | 02-14-2013 |

20140315587 | METHODS AND APPARATUSES FOR MANAGEMENT OF SMS MESSAGE IDENTIFICATIONS IN A MULTI-MODE DEVICE - Aspects of the present disclosure propose systems and methods for managing assignment of short message service (SMS) message identifications (IDs) in a multimode device (e.g., mobile station). The proposed methods ensure that a unique message ID is assigned to each SMS transmitted by the mobile station (MS). Each retransmission of the SMS messages may be assigned a message ID similar to or the same as the previous transmission(s) of the SMS message. As a result, a network messaging center may be able to identify duplicate SMS messages that are marked with unique message IDs even if they are transmitted on different air interfaces and/or by different modems (modulators/demodulators). | 10-23-2014 |

20110096732 | SYSTEMS AND METHODS FOR MEASURING AND REDUCING LATENCY OF RADIO LINK FLOWS - Disclosed are systems, methods and computer program products for measuring and reducing latency of radio link flows having different quality of service (QoS) reservations. An example method comprises establishing one or more radio link flows with an access gateway, wherein each radio link flow has a different QoS reservation, transmitting at least one transport layer protocol message having a predetermined size on each radio link flow to the echo service of the access gateway, receiving at least one response message on each radio link flow from the access gateway, computing the round trip time (RTT) for the transmitted and received messages on each radio link flow, and modifying QoS reservations of the one or more radio link flows based on the computed RTT for the one or more radio link flows. | 04-28-2011 |
20120307621 | SYSTEM, APPARATUS, AND METHOD FOR REDUCING RECOVERY FAILURE DELAY IN WIRELESS COMMUNICATION SYSTEMS - A method, an apparatus, and a computer program product for wireless communication are provided in which blocking of LTE access due to Internet Protocol Multimedia Subsystem (IMS) Packet Data Network (PDN) recovery failure is prevented. The blocking may be caused by detach and immediate attach to LTE because of internal or other commonly executed network procedures. Recovery procedures may be modified to avoid prolong periods when access to the PDN is prevented based on long backoff delays set by an operator for PDN failure conditions. Based on a reason for failure to reconnect, a backoff period may be selected from an operator define minimum backoff time and a locally configured minimum backoff time. | 12-06-2012 |
