A communication system formed by a private wireless network that can be used
with
public wireless networks using a public wireless protocol, such as GSM, and typically
includes public networks, such as PSTN, ISDN and the Internet, using a wired-packet
protocol, such as IP. The private network also typically includes a local area
network (LAN) and the private network typically connects to the public networks
using the wired-packet protocol, such as IP. The public and private wireless networks
operate with the same public wireless protocol, such as GSM, and the private wireless
network additionally operates with the wired-packet protocol, such as IP. In this
environment, multiple wireless cells are present and inter-cell handovers employ
multiple protocols including the wired-packet protocol.
