Publication number: 20170164144Abstract: Embodiments herein provide a method for sharing information of location of a communication device during a voice call over the non-cellular technology. The method includes acquiring cellular location information directly or indirectly from a cellular network during the voice call. Further, the method includes sending the cellular network parameters in a Session Initiation Protocol (SIP) header field to a core network. The SIP P-header can be P-Alternate-Access-Network-Info. The cellular network parameters correspond to location related information of the communication device. The proposed method provides the location information of the communication device without relying on GPS information.Type: ApplicationFiled: December 2, 2016Publication date: June 8, 2017Inventors: Akhil Madan Panchabhai, Manish Dass, Venkatesh Gowni Ramakrishna, Vijay Saha, Ravikumar Kalaimani

Patent number: 8892097Abstract: Methods and apparatus are provided for selecting a serving cell in a communication network for reducing power consumption in a UE, is provided. Network topology information is determined by obtaining cell rank information for the UE, extracting a mobility state of the UE, and applying a double moving average principle to the cell rank information of the UE. The network topology information is employed to determine a change in network topology. Radio Frequency (RF) scans are optimized based on the network topology.Type: GrantFiled: February 11, 2013Date of Patent: November 18, 2014Assignee: Samsung Electronics Co., LtdInventors: Avijit Manna, Kirti Keshav, Prakash Rao, Ravikumar Kalaimani

Patent number: 8442554Abstract: A method and system for identifying the location of a mobile device in a wireless communication network includes identifying Hierarchical Cell Structure (HCS) priority number of a cell in which the mobile device is currently camped. A first positioning method is selected to identify the location of the mobile device when the HCS priority number is greater than a first predefined number, and a second positioning method is selected when the HCS priority number is smaller than a second predefined number. The method also performs a probabilistic method to select a positioning method from the first posting method and the second positioning method when the HCS priority number is between the first predefined number and the second predefined number.Type: GrantFiled: May 31, 2011Date of Patent: May 14, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Kirti Keshav, Ravikumar Kalaimani

Patent number: 7535846Abstract: Disclosed is a method for handling inter-RAT cell measurement in a dual-mode UE in a connected mode, which supports both GSM/GPRS (Global System for Mobile communication/General Packet Radio Service) RAT (Radio Access Technology) and UMTS (Universal Mobile Telecommunications System) RAT. A UTRAN (UMTS Terrestrial Radio Access Network) of the UMTS RAT transmits a measurement control message to a URRC (UMTS Radio Resource Control) of a UMTS network layer in the UE. Upon receiving the measurement control message, the URRC sends a measurement request for GSM cells to an RR/GRR (Radio Resource/GPRS Radio Resource) of a GSM/GPRS network layer. The RR/GRR activates a GSM physical layer and sends a measurement request for the GSM cells to the GSM physical layer. The GSM physical layer performs measurement on the GSM cells and reports a measurement value to the RR/GRR. The RR/GRR reports the measurement value for GSM cells, received from the GSM physical layer, to the URRC.Type: GrantFiled: May 15, 2003Date of Patent: May 19, 2009Assignee: Samsung Electronics Co., LtdInventors: Yu-Shin Kim, Ravikumar Kalaimani, Goli Naga Santha Mohan Rao, Jang-Ki Min, Bhishma V
