20150053572 | HYDROMETALLURGICAL PROCESS FOR THE RECOVERY OF TELLURIUM FROM HIGH LEAD BEARING COPPER REFINERY ANODE SLIME - A hydrometallurgical process is provided for the recovery of tellurium as elemental tellurium powder from copper refinery anode slime containing high amount of lead. The process involves the removal of copper and lead from anode slime followed by the recovery of tellurium as elemental powders. An economical and environment friendly process is provided for producing tellurium from a high lead bearing anode slime as it involves only hydrometallurgical techniques and thereby avoids emission of any polluting gases and has an efficiency of 85 to 90%. The developed process of recovering tellurium as elemental powders from copper refinery anode slime is beneficial in the production of pure tellurium instead of tellurium compounds. It helps raise the profit margin of a non-ferrous metal industry dealing with extraction of copper from ores and treatment of anode slime for the recovery of other metal values. | 02-26-2015 |

20150237597 | ENHANCED TUNE-AWAY MECHANISM DURING SIGNALING PROCEDURE IN MULTIPLE SUBSCRIPTION COMMUNICATIONS - In various aspects of the disclosure, an improved tune-away technique is utilized by a user equipment (UE) for wireless communication during a signaling procedure for a primary subscription with reduced impact on paging performance of one or more secondary subscriptions. The UE performs a signaling procedure including receiving at least one protocol data unit (PDU) of a signaling radio bearer (SRB) message from a first network associated with the first subscription. The UE further determines a message type of the SRB message based on the at least one received PDU. If the message type indicates that the SRB message includes a signaling non-critical message, the UE further performs a tune-away procedure to communicate with a second network associated with the second subscription, while the signaling procedure is ongoing. | 08-20-2015 |
20150237672 | DCH TO NON-DCH STATE SWITCHING OF USER EQUIPMENT IN UMTS - A method and apparatus for radio resource control (RRC) state transitions of a user equipment (UE) are provided. For the RRC state transitions of the UE, for example, a reconfiguration message is received at the UE while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states. The reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of RRC states. A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state. | 08-20-2015 |

20130273915 | METHOD AND APPARATUS FOR EXPEDITED WIRELESS DEVICE HANDOVER - The present disclosure presents a method and apparatus for expedited mobile device handover that include performing one or more handover tasks in parallel that have previously been performed exclusively in serial. For example, the disclosure presents a method for wireless device handover, which may include acquiring a target cell, ascertaining a system frame number (SFN) of the target cell, calculating a connection frame number (CFN) for a dedicated channel (DCH) transmission, and reconfiguring a dedicated physical channel (DPCH) based on the calculated CFN. In addition, such an example method may include, while performing at least one of the ascertaining of the SFN, the calculating of the CFN, and the reconfiguring of the DPCH, contemporaneously performing at least one of establishing a downlink dedicated physical channel (DL-DPCH), establishing a synchronization with the target cell, and establishing an uplink dedicated physical channel (UL-DPCH) subsequent to the downlink synchronization. | 10-17-2013 |
20140022989 | METHOD AND APPARATUS FOR DYNAMICALLY CONFIGURING A CELL UPDATE MESSAGE - The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example, the method may include determining that a size of the cell update message at the UE is above a threshold value after a “measured results on random access channel (RACH)” information element (IE) is excluded from the cell update message. Furthermore, such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value.

20140254506 | DEVICES AND METHODS FOR FACILITATING H-RNTI UPDATES IN NETWORK-INITIATED CELL REDIRECTION - Access terminals are adapted to facilitate updating an access terminal with a valid H-RNTI in response to a network-initiated redirection of an access terminal from a serving cell to a target cell in a wireless communications system. According to at least one example, an access terminal can acquire a target cell in response to a network-initiated redirection indicated by a received redirection message. A determination can be made that a current radio network temporary identity (RNTI) associated with the access terminal is invalid for use in the target cell. In response to the determination that the RNTI is invalid for use in the target cell, a cell update procedure may be initiated to obtain a valid RNTI for use in the target cell. Other aspects, embodiments, and features are also included. | 09-11-2014 |
20140274083 | METHOD AND APPARATUS FOR IMPROVING RE-TRANSMISSION OF RECONFIGURATION MESSAGES - The present disclosure presents an improved method and apparatus for re-transmission of reconfiguration messages. For example, the disclosure presents a method for detecting that a reconfiguration complete message is transmitted from a user equipment (UE) to a network and initiating a reconfiguration re-transmission timer upon the detection. In addition, such an example method, may include determining that the UE has not received a layer two acknowledgement (L2 ACK) message for the transmitted reconfiguration complete message from the network prior to expiration of the reconfiguration re-transmission timer and triggering a cell update message to the network in response to the determination that the UE has not received the L2 ACK message. As such, improved re-transmission of reconfiguration messages may be achieved. | 09-18-2014 |

Additionally, the example method may include determining that the configuration information includes invalid configuration information. Moreover, the example method may include performing at least one remedial action to ensure that the UE is able to transmit the uplink transmissions based on determining that the configuration information includes invalid configuration information. | 07-16-2015 |
20150223148 | TECHNIQUES FOR READING SYSTEM INFORMATION IN WIRELESS COMMUNICATIONS - Described herein are various aspects related to determining whether to read system information of a network entity. A user equipment (UE) can receive system information transmitted by a network entity. The UE can analyze one or more parameters of the system information to determine whether system information for the network entity has changed when a value tag broadcasted in the system information is equivalent to a stored value tag for the network entity; thus the UE can utilize more than just the value tag, such as system information size, system information scheduling, a value tag in master information, and/or the like, at least in instance where the value tag may be the same in different transmissions of the system information. The UE can process the system information for the network entity based at least in part on determining that the system information for the network entity has changed. | 08-06-2015 |

20150019822 | System for Maintaining Dirty Cache Coherency Across Reboot of a Node - Nodes in a data storage system having redundant write caches identify when one node fails. A remaining active node stops caching new write operations, and begins flushing cached dirty data. Metadata pertaining to each piece of data flushed from the cache is recorded. Metadata pertaining to new write operations are also recorded a corresponding data flushed immediately when the new write operation involves data in the dirty data cache. When the failed node is restored, the restored node removes all data identified by the metadata from a write cache. Removing such data synchronizes the write cache with all remaining nodes without costly copying operations. | 01-15-2015 |
