20090168751 | METHOD TO PREVENT HYPER FRAME NUMBER DE-SYNCHRONIZATION IN A WIRELESS COMMUNICATION SYSTEM - A method for HFN synchronization in a wireless communication system. The method includes toggling an RSN bit value in RESET PDU, after single sided re-establishment of RLC entity. A RESET PDU with the toggled RSN bit value is transmitted to a receiver. The HFN value then updated according to a RESET ACK PDU. | 07-02-2009 |
20090219828 | METHOD AND SYSTEM FOR MANAGING DATA TRANSFER - A method and a system for managing data transfer are provided. The method includes receiving a poll request for a status report on Protocol Data Units (PDUs) transmitted sequentially during the data transfer, determining a status reporting range of the PDUs to be accounted in the status report based on a sequence number in the poll request, and providing the status report with status information on a receipt or a loss of the PDUs within the status reporting range during the data transfer. | 09-03-2009 |
20120183142 | METHOD AND APPARATUS FOR APPLYING A CIPHERING CONFIGURATION IN A WIRELESS COMMUNICATION NETWORK - Methods and devices are provided for applying a ciphering configuration in a wireless communication network. The method includes initiating an entity reset procedure by a first entity in the wireless communication network; synchronizing Hyper Frame Numbers (HFNs) associated with the first entity and a second entity, respectively, during the entity reset procedure; and applying a new ciphering configuration by the first entity and the second entity, upon completing the entity reset procedure, without updating the synchronized HFNs associated with the first entity and the second network, respectively. | 07-19-2012 |
20120220299 | METHOD AND SYSTEM TO HANDLE A SIGNALING CONNECTION RELEASE PROCESS IN A WIRELESS COMMUNICATION SYSTEM - A method and system for handling a signaling connection release process in a wireless communication system is provided. The method includes receiving a reconfiguration message by a mobile device. The method also includes triggering a serving radio network subsystem (SRNS) relocation process for the mobile device based on the receiving. Further, the method further includes causing a timer to cease miming and resetting the timer to a predefined value. Moreover, the method includes clearing a variable associated with the timer from the mobile device. The system includes a mobile device, a radio network controller, and a communication interface. | 08-30-2012 |
20140204920 | METHOD TO PREVENT HYPER FRAME NUMBER DE-SYNCHRONIZATION IN A WIRELESS COMMUNICATION SYSTEM - Methods and apparatus are provided for HFN synchronization in a wireless communication system. If re-establishment of an RLC entity occurs during a pending RLC reset procedure, the pending RLC reset procedure is aborted and the re-establishment of the RLC entity is performed. A first RC variable included in a RESET PDU is incremented. The pending RLC reset procedure is restarted. The RESET PDU including the incremented first RC variable is transmitted. A RESET ACKnowledgement (ACK) PDU for the RESET PDU including a second RC variable is received. The second RC variable included in the received RESET ACK PDU is checked and the received RESET ACK PDU is accepted based on the checking result. | 07-24-2014 |
20150109918 | METHOD AND SYSTEM FOR OPTIMIZING USER EQUIPMENT PERFORMANCE IN LONG TERM EVOLUTION CO-EXISTENT NETWORKS - The present invention provides a method and system for optimizing user equipment performance by having faster resumption of services during co-existence of LTE Frequency division duplexing (FDD) and Time division duplexing (TDD) networks. The method includes determining whether the UE is able to acquire essential system information (SI) associated with a cell or frequency which is barred by the UE. Further, the method includes removing the barring restriction conditionally for that cell or frequency which is barred by the UE if the UE is able to acquire the essential system information associated with the cell frequency. Furthermore, the method includes, allowing the UE to camp on the cell or frequency whose essential SI has been acquired by the UE and resuming the service with the cell and frequency. Furthermore, it also includes the method to have seamless handover between TDD and FDD and vice versa. | 04-23-2015 |
20150109946 | METHOD AND SYSTEM OF CELL SELECTION FOR A HANDOVER DURING COEXISTENCE OF LTE FDD/TDD NETWORKS - A method and system for performing a cell selection in case of a handover during co-existence of LTE TDD/FDD networks is provided. The method includes receiving a handover message from a network along with a target cell for the handover. The method includes scanning for primary target cells, upon a failure in detecting the target cell by the User Equipment. The method includes storing the detected primary target cells in a measurement database by the UE. The UE initiates scanning on the stored primary target cells in the measurement database for performing the cell selection during the handover. Further, the UE after the performing the cell selection, sends the re-establishment request message along with the measurement database to the network. | 04-23-2015 |
20150163845 | METHOD AND SYSTEM TO HANDLE A SIGNALING CONNECTION RELEASE PROCESS IN A WIRELESS COMMUNICATION SYSTEM DURING SRNS RELOCATION PROCEDURE - A method in a wireless communication system is provided. The method includes receiving a reconfiguration message, and stopping and resetting a timer inhibiting a mobile device from transmitting a signaling connection release indication message while the timer is running and clearing any value associated with the timer if the received reconfiguration message is for radio bearer reconfiguration and a new universal mobile telecommunications system terrestrial radio access network (UTRAN) radio network temporary identifier (U-RNTI) is included. | 06-11-2015 |
