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.
