An implementation of interworking system for CDMA wireless data communications

Wireless data services and systems represent a rapidly growing and increasingly important segment of the communications industry. We describe the implementation of an interworking system for CDMA wireless data services between the mobile subscriber with a data terminal and the public subscriber in the public switched telephone network (PSTN) with a personal computer or G3 facsimile terminal. This module can be used to make a search of information, which is included in the database of a data network. To adapt this module for the mobile communication network, we suggested the use of a system structure in parallel with the mobile switching system in order to reduce the influence of the network configuration. This system can be used to provide an end to end data communication service and a means of searching for information in databases.
