Method of providing burst timing for high-speed data transmission in a base station transceiver system of a mobile communication system

Abstract

A method of establishing a supplemental channel (SCH) to provide burst timing for high-speed data transmission in a mobile communication system is disclosed. In the SCH establishing method, a source base station transceiver determines that a traffic burst exists and sends a target base station transceiver a burst request message. The burst request message includes forward and reverse burst timing information and channel use time information, which is determined in consideration of a discontinuous transmission (DTX) mode, in order to reserve necessary resources, when a large amount of high rate data is to be transmitted. Then, the target base station transceiver sends the source base station transceiver a burst response message including information about resources committed to the traffic burst.

Description

[0001]This Application claims the benefit of 60 / 133,790, filed May 12, 1999.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to a method of providing burst timing in a base station (BS) of a mobile communication system, and in particular, to a method of providing forward and reverse burst timing with respect to the time of using a supplemental channel (SCH) and a supplemental code channel (SCCH) for rapid transmission of a large amount of data in a BS, taking into account a discontinuous transmission (DTX) mode.[0004]Specifically, the present invention relates to a method of providing burst timing definable with respect to the use time of a physical channel and the start and end time of data and a method of supporting an AAL5 protocol for high-speed data transmission between BTSs by a base station transceiver system (BTS) and a base station controller (BSC) in a mobile communication system under a ratio channel environment which...

AI Technical Summary

Benefits of technology

[0076]It is another object of the present invention to provide the AAL5 (ATM Adaptation Layer 5) protocol, which is used to effectively transmit high rate data, in an A3 traffic channel protocol stack field.

[0078]It is still another object of the present invention to provide a method of defining forward and reverse burst timing messages in one message or defining them separately to be available in either direction as well as both directions, and expressing the start time of a burst in various units, to thereby implement a burst operation at a more accurate time.

Problems solved by technology

However, a physical channel is not necessarily created to set up a new logical channel.

Therefore, the protocol stack is not fit for high rate data.

Therefore, a BS cannot adequately identify channels.

Furthermore, high rate data cannot be transmitted since only the AAL2 protocol, which is used for voice service, is defined in the A3 Traffic Channel Protocol Stack.

The DTX duration of a reverse SCH and SCCH is not provided, thereby making it impossible to perform rapid packet service in a BS.
