Abstract

In our recent proposal based on working proto- type, the iDEN infrastructure is extended to support Dispatch service for Desktop IP network Client (DIPC). This extension includes the Desktop Dispatch Access Server (DDAS) which allows a computer connected to an Internet (Networked Multimedia Computer) to send and receive signaling and voice information over an IP network. The com- puter's microphone and speakers are used for audio signal I/O so it can be used instead of phone for voice communications.

INTRODUCTION

  In our recent proposal based on working proto- type, the iDEN infrastructure is extended to support Dispatch service for Desktop IP network Client (DIPC). This extension includes the Desktop Dispatch Access Server (DDAS) which allows a computer connected to an Internet (Networked Multimedia Computer) to send and receive signaling and voice information over an IP network. The com- puter's microphone and speakers are used for audio signal I/O so it can be used instead of phone for voice communications.

  Accessing iDEN network for Dispatch commu- nication from Desktop IP Client computer requires its identification by the network. In iDEN this oper- ation is performed during a process of registering MS IMSI with the DAP. Conventional PC does not have built in unique identity which permanently available after normal hardware and software upgrades done by the user. Therefore, PC authenti- cation is not straightforward process. Besides assigning permanent ID to the DIPC creates duplicative record for the user who has already reg- istered (iDEN) Mobil Subscriber unit (MS) and complicates use of Desktop Dispatch access since tbe user normally will use only one of access term- ml DIPC or SU at the same time.

MOTIVATION

  iDEN telephone provides either Cellular or Dispatch voice communication services at a time. With the introduction of additional access device (DIPC), these two services could be provided s...
