frequency and vice-versa (col. 1, lines 52-55). A user receives
local pages at a home city frequency, and pages at a nationwide
frequency when outside of the user's local area (col. 2, lines
43-48). Transmission at the nationwide frequency is via
satellite or land-line link as shown in figure 1. When a user
leaves city L1, the user reports his absence to the local Radio
Common Carrier (RCC), which adjusts the system so that pages for
the user will be diverted to the nationwide system. The
nationwide system then transmits the messages to the user in all
cities or to a specific city (col. 2, lines 60-66). If a user
travels from city L1 to city L2, the pager finds a special code
for L2 (absence of L1) in the transmissions and determines that
it is not in city L1. The pager/receiver then switches channels
to the nationwide frequency (col. 6, lines 3-9).
We find that Gaskill (col. 4, lines 21-28) is directed to a
paging system that operates within any desired area, including
local, regional, national, continental, and worldwide
communication capability, without displacing local area access to
the paging system. Paging requests are transmitted from local
area transmitting means in the form of packets. Page requests
are transmitted by telephones 24 and personal computers (col. 6,
lines 40-43). A sending user transmits a request by dialing the
