Accordingly, service providers who are now using TDMA are in the process of deciding whether to migrate on a path followed by GSM or IS-95 adherents. The time-to-market of the various 3G technologies varies because of the varying maturity of the underlying technology. The generic steps in the deployment process for any new wireless system involve the building and testing of several prototype systems, setting a firm specification for systems and handsets, optimizing system and handset performance, and adding rich feature sets for multimedia.
The new architecture will need to be based on the paradigm that every user is potentially mobile, and the network is to be able to carry all types of traffic, some requiring strict quality of service (QoS) and others requiring only best effort service. Some key areas that are being studied aggressively are (1) transporting heterogeneous traffic in a heterogeneous access network using Internet protocols, (2) seamless mobility, (3) seamless QoS and resource management, (4) ubiquitous networking for dynamic ad hoc networks, (5) security, and (6) network services and end user applications.

With nontransparent access, the user credentials are sent to the remote PDN and the user is permitted to access this PDN only if he or she is successfully authenticated. In this case, the user is assigned an IP address from the address space of the remote PDN. 3). , corporate networks) or ISPs, whereas the transparent access is most appropriate for users who do not maintain subscriptions to third-party ISPs or intranets.
