Embodiment Construction

[0012] The invention enables the mobile terminal (MS) to send or receive short data packets through the existing common channel and packet or packet data service node (PSDN), without using the forward / reverse traffic channel. This MS could be a telemetry control unit, an inventory control unit for a vending machine, a pager, etc. To describe this embodiment, various abbreviations are used, and their definitions are as follows:

Abstract

A method and system is provided for controlling data transfer using a short data burst mechanism between a mobile station (MS) and a base station (BS). After identifying that a short data burst mechanism is desired to be used for transmitting data between the MS and the BS, the data is transmitted over a common channel used for communication between the MS and the BS without having to establish a communcation link between the MS and the BS over a traffic channel.

Description

[0001] refer to [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 232,910, filed September 15,2000. Background technique [0003] The present invention generally relates to data communication in a communication network, and in particular relates to a method and system for transmitting data information using a public or common channel. In a typical CDMA (Code Division Multiple Access) communication system, when a mobile terminal (MS) is initialized, it must acquire a traffic channel before it can exchange data with a base station. As an option, the MS maintains only minimal contact with the base station through common channels in a dormant state. Occupying a business or traffic channel (traffic channel) costs a lot. For example, functions such as power control, handoff (handoff) and channel resource management must be performed so that the MS can work in the effective area of ​​the communication network, because various intelligent f...
