20130329635 | Method and Apparatus for Reporting Measurement Result in Wireless Communication System - Provided an apparatus and a method for reporting a measurement result in a wireless communication system. A terminal receives report conditions and a measurement setting including a report for position information from a base station. When a measurement report is triggered, the terminal determines whether valid position information is available and the measured result is transmitted to the base station. When the valid position information is not available, the measured result includes serving cell information and adjacent cell information. | 12-12-2013 |
20140126519 | METHOD FOR CONTROLLING RADIO RESOURCE ALLOCATION IN MOBILE COMMUNICATION SYSTEM - In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource. | 05-08-2014 |
20140192631 | METHOD FOR DETECTING SECURITY ERROR IN MOBILE TELECOMMUNICATIONS SYSTEM AND DEVICE OF MOBILE TELECOMMUNICATIONS - According to one embodiment, a method of performing a re-establishment procedure in a mobile communication system includes: receiving at least one packet data convergence protocol (PDCP) control plane data unit; performing an integrity check on the at least one PDCP control plane data unit; identifying an integrity check failure with regard to the at least one PDCP control plane data unit; and performing a re-establishment procedure if the integrity check failure is identified to exist with regard to the at least one PDCP control plane data unit. | 07-10-2014 |
20140233490 | METHOD OF DETECTING AND HANDLING AN ENDLESS RLC RETRANSMISSION - Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and more particularly, to a method of effectively detecting and handling endless RLC retransmission so as to prevent endless RLC re-transmission occurring between the terminal and a network in an Evolved Universal Mobile Telecommunications System (E-UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system. | 08-21-2014 |
20150044972 | Method for Logging Measurement Result in Wireless Communication System and Apparatus for the Same - A method for logging measurement results in a wireless communication system is provided. The method includes: receiving a logged measurement configuration from a network, the logged measurement configuration comprising information for performing logged Minimization Driving Test (MDT); measuring at least one cell based on the logged measurement configuration; determining whether the measurement result has importance for logging; if a storage space for logging is enough for additionally logging, setting an importance tag of the measurement result to a predetermined value in accordance with the determination; and logging the measurement result and the importance tag in the storage space. | 02-12-2015 |
