    Summary form only given. Wireless data networks are unique in that there are three key aspects to a complete solution: the network, the radio modem and the application. As wireless data networks emerged, the focus was on architecting the network and designing small, power efficient modems. Little effort was focused on the connectivity of the network (and modem) to higher operating systems and appl... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (372 KB)

    Delays in accessing the service (delays in user/terminal authentication or call set up) and/or denial of service due to non-availability of resources (call blocking, hand-off failure) are key traffic performance parameters for PCS (personal communication service). These parameters will have a significant impact on the quality of service perceived by the end users of PCS. Suitable standards (target... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (368 KB)

    The growing number of services now available through modern communication networks has increased the complexity of terminals. This is why it is important to simplify the man-machine interaction in order to allow an efficient use of terminal resources also by not-skilled persons. Another important point is to add an appropriate degree of intelligence to allow the automatic interaction between the u... View full abstract»

    One feature of PCS is that a user can make and receive calls at any locations using the same phone number. This is number mobility. In order to provide number mobility, the network has to be able to locate the called user and then route the call. The process involves updating network's knowledge about user's current location and mapping of the PCS number received from the calling user to the calle... View full abstract»
