Abstract

CDMA specifications provide three types of data services: Short message service (SMS), circuit switched, and packet switched data. Circuit-switched data services require a dial-up to a data service. The benefit of using a circuit-switched data service is the ability to utilize existing wireless equipment i.e. a cell phone as a modem to connect to a data network, thereby reducing overall hardware costs. Once connected with packet data services, a mobile terminal utilizes a constant data rate for wireless data services. Packet data services are cost effective, especially for highly frequent use. We have increased the cost-effectiveness of Qualcomm software by reducing or in some cases eliminating setup and transmission costs associated with wireless data calls. As no PSTN call setup or modem training time is required for implementation, the end-to-end connection setup time is drastically reduced. The software module is implemented on the Qualcomm MSM3000 chipset to support support interactive applications linked with serial interface. This module enables the mobile terminal to directly connect the server with TCP using DSSock Socket API in DMSS3000. It can also be adapted to many other PC-based applications via direct-linked RS232C control.
