Patent number: 7317920Abstract: A system and method is provided for fast call set-up in a wireless communication system. A base station sets up a call from a mobile station by sending null frames to the mobile station on a forward traffic channel instead of sending a base station acknowledgement order. The mobile station sends a traffic channel preamble to the base station on a reverse traffic channel instead of sending a mobile station acknowledgment order. The fast call set-up procedure of the present invention reduces the call set-up time from approximately two (2) to three (3) seconds to approximately two hundred milliseconds (200 msec) to three hundred milliseconds (300 msec).Type: GrantFiled: September 10, 2003Date of Patent: January 8, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Purva R.

Patent number: 7302261Abstract: For use in a wireless network, a mobile station that can selectively use the reduced slot cycle mode under the control of a first wireless network base station. The mobile station comprises: 1) a message controller for communicating in a paging channel with the first base station; and 2) a reduced slot cycle controller coupled to the message controller for causing the message controller to transmit to the first base station a first Release Order message comprising a minimum reduced slot cycle index (SCI) value requested by the mobile station. The reduced slot cycle controller is further capable of receiving from the first base station a second Release Order message comprising a selected slot cycle index (SCI) value at which the mobile station will operate.Type: GrantFiled: January 23, 2004Date of Patent: November 27, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Purva R.

Publication number: 20070091788Abstract: A system for providing parallel, concurrent transmission of multiple DRC elements is disclosed. An assignment element assigns, for each access terminal in an access network, two DRC-related parameters. A first parameter is assigned to uniquely identify a given access terminal. A second parameter is assigned to identify DRC traffic for that access terminal. An allocation message, such as a traffic channel allocation message, is modified to communicate the parameters from the access network to an access terminal. The access terminal processes its DRC traffic with both parameters, enabling the access network to identify its transmissions regardless of time multiplexing.Type: ApplicationFiled: May 10, 2006Publication date: April 26, 2007Applicant: SAMSUNG ELECTRONICS Co., LTD.Inventors: Purva Rajkotia, Sanjaykumar Kodali, Chanakya Bandyopadhyay, Rajasimman Vijayasimman
