The Research And Development Of Data Service Platform Of Brew

A method to develop Trunking System PTT (Push To Talk) encrypt call terminal by utilizing BREW in CDMA system has been elaborated. The detailed design has realized the process of the Trunking System Encrypt PTT service, combined management towards Encrypt PTT service to bring up the designing way of thinking and ensure its realization. The design for software and hardware compatibility on relevantly Encrypt Data Module Interface has been realized, so as to make the form of encrypt algorithm exist with hardware or software package. An open user interface has been designed to meet customers' needs, so that the consumer can expediently realize the update of encrypt algorithm. On the design of the user interface of UI software, its own window mechanism use the development management platform has been put forward for the support of multiple reuse, password verification and the kind of interactive interface design. On the platform the management of window mechanism is realized, encapsulate the data of the binding, and the design of control lib. Through making use of this platform the fleetness to efficiently develop the certain standard and unified style operation interface. Finally, encrypt PTT function will perform effective work and have the good and follow-up development.
