Abstract

In accordance with the principles of the present invention, a method and apparatus for filtered wireless communications is provided. The method provides a filtered wireless zone. Signaling channels normally serving a geographic vicinity are scanned, with the channel identity and the system identity of each signaling channel recorded. A transmitter-receiver is commanded to such channel. A signaling channel marker is radiated. A new signaling channel assignment message is sent, sending handsets to a new capture channel. An appropriate signal is radiated to keep the handsets locked to the new capture channel. The transmitter-receiver then ceases radiating on the first channel, and proceeds to the second external signaling channel previously recorded. The transmitter-receiver repeats this process for all the external signaling channels previously located. In a further embodiment, a virtual phone booth can be provided within the filtered wireless zone.

Dependent claims

A filtered wireless zone comprising:

a system control connected to a signaling channel receiver outside the filtered wireless zone and a system signaling channel transmitter-receiver within the filtered wireless zone;
the signaling channel receiver arranged to receive a signaling channel of one or more cell sites in a geographic vicinity;
the system signaling channel transmitter-receiver arranged to cover the filtered wireless zone with a signal;
a signal channeling marker signal transmitted by the system signaling channel transmitter-receiver in the filtered wireless zone;
and
a new signaling channel assignment message transmitted by the system signaling channel transmitter-receiver in the filtered wireless zone, thereby sending handsets to a new capture channel;
whereby when a handset has been so captured a call for that handset is routed to voice-mail or other processing, as previously configured for that handset;
further whereby when a handset that has been so captured attempts to place a call, the call attempt is blocked;
further whereby if a handset that has been so captured attempts to place an emergency call, the call is routed to an emergency call line.
