Patent number: 8855091Abstract: The present invention relates to a mobile communications system, and particularly, to a method for determining whether to keep or deactivate an activated Idle mode Signaling Reduction (ISR) feature for a terminal in a mobile communications system. In case of the UE's intra-SGSN mobility and intra-MME mobility, when deciding, by a mobility management node, ISR activation for a UE in an IMS network environment where heterogeneous mobile communications networks (e.g., E-UTRAN and UTRAN/GERAN) interwork with each other, considered are not only whether the mobility management node can support an ISR feature, and whether the UE can use IMS voice, but also conditions (information) on whether each mobility management can support IMS voice over PS session. This may allow an incoming voice call to the UE from the IMS network to be delivered through a first trial, to a domain (PS domain or CS domain) selected with consideration of access network situations.Type: GrantFiled: December 27, 2010Date of Patent: October 7, 2014Assignee: LG Electronics Inc.Inventors: Laeyoung Kim, Hyunsook Kim, Taehyeon Kim, Saso Stojanovski, Arnaud Vedrine

Publication number: 20130017829Abstract: The present invention relates to a mobile communication system and, more particularly, to a method for performing offline indication of a machine type communication (MTC) device in an MTC service. A network entity checks (or searches) whether or not an MTC device is out of monitoring or management because it is in an offline state. A network entity repeatedly transmits a signal for checking whether or not the UE is currently in an offline state to the UE during operation time of a timer, namely, during a detection time, or checks a signal (e.g., a message of an attach procedure, a message of a location registration procedure, and the like) transmitted by the UE during the detection time to check whether or not the UE is in an offline state. When the UE is checked to be in an offline state, the network entity informs an MTC server or an MTC user accordingly, to thus automatically manage a loss, malfunction, or the like, of the MTC device.Type: ApplicationFiled: January 7, 2011Publication date: January 17, 2013Applicant: LG ELECTRONICS INC.Inventors: Taehyeon Kim, Hyunsook Kim, Laeyoung Kim, Saso Stojanovski, Arnaud Vedrine

Patent number: 6898194Abstract: A method and system are disclosed for fast access to an uplink channel for a mobile station in a packet data radio network. A plurality of mobile stations are assigned to a first uplink channel. A mobile station assigned to the first uplink channel transmits in an uplink transmission block real time information. In response to the transmission, a base station reassigns the other mobile stations that are assigned to the first uplink channel and are involved in the communication of real time information in a downlink transmission block immediately following the uplink transmission block. Thereafter, the first mobile station continues transmitting real time information on the first uplink channel.Type: GrantFiled: May 9, 2000Date of Patent: May 24, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Arnaud Védrine

Patent number: 6707808Abstract: Fast access to an uplink channel for a mobile station in a packet data radio network can be obtained by causing a collision in an uplink radio block. A first uplink block of the uplink channel is initially assigned to a first mobile station. During the first uplink block, however, a transmission from a second mobile station is received on the uplink channel. In response, a subsequent uplink block of the uplink channel is assigned to the second mobile station.Type: GrantFiled: March 17, 2000Date of Patent: March 16, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Arnaud Vedrine
