Abstract

In accordance with the principles of the present invention, a wireless virtual phone booth is provided within a filtered wireless zone. A filtered wireless zone is provided. A geographically limited signal is contained within the filtered wireless zone. When a handset in the filtered wireless zone attempts to place a call, the call attempt is blocked. In addition, a handset in the geographically limited signal contained within the filtered wireless zone is allowed to place calls.

Claims

1-48. -48. (canceled)

49. A virtual phone booth comprising:

a filtered wireless zone; and

a geographically limited signal contained within the filtered wireless zone;

whereby when a handset in the filtered wireless zone attempts to place a call, the call attempt is blocked;

further whereby a handset in the geographically limited signal contained within the filtered wireless zone places a call, the call is allowed.

50. The virtual phone booth of claim 49 further wherein the geographically limited signal contained within the filtered wireless zone is generated by a set of transmitter-receivers.

51. The virtual phone booth of claim 49 further wherein the geographically limited signal contained within the filtered wireless zone allows calls to be received.

52. The virtual phone booth of claim 49 further wherein certain calls made from a handset in the filtered wireless zone are allowed.

53. The virtual phone booth of claim 49 further wherein the filtered wireless zone comprises:

a system control, the system control arranged to receive a signaling channel of one or more cell sites in a geographic vicinity and to cover the filtered wireless zone with a signal;

a signal channeling marker signal transmitted by the system control in the filtered wireless zone; and

a new signaling channel assignment message transmitted by the system control in the filtered wireless zone, thereby sending handsets to a new capture channel.

54. The virtual phone booth of claim 49 further wherein the signal channeling marker signal comprises the identity of the ordinary system it is supplanting.

55. The virtual phone booth of claim 49 further wherein the strength of the geographically limited signal is higher than signal strengths normally received in the filtered wireless zone.

56. The virtual phone booth of claim 49 further wherein the signal comprises Frequency Division Multiple Access (FDMA) signals.

57. The virtual phone booth of claim 49 further wherein the signal comprises Time Division Multiple Access (TDMA) signals.

58. The virtual phone booth of claim 49 further wherein the signal comprises Code Division Multiple Access (CDMA) signals.

59. The virtual phone booth of claim 49 further wherein the signal comprises Global System for Mobile Communications (GSM) signals.

60. The virtual phone booth of claim 49 further wherein the signal comprises transmission control protocol/internet protocol (TCP/IP) signals.

61. A method of creating a virtual phone booth comprising:

establishing a filtered wireless zone; and

transmitting a geographically limited signal contained within the filtered wireless zone;

whereby when a handset in the filtered wireless zone attempts to place a call, the call attempt is blocked;

further whereby a handset in the geographically limited signal contained within the filtered wireless zone places a call, the call is allowed.

62. The method of creating a virtual phone booth of claim 61 further including generating the geographically limited signal contained within the filtered wireless zone by a set of transmitter-receivers.

63. The method of creating a virtual phone booth of claim 61 further including the geographically limited signal contained within the filtered wireless zone allowing calls to be received.

64. The method of creating a virtual phone booth of claim 61 further including allowing certain calls made from a handset in the filtered wireless zone.

65. The method of creating a visual phone booth of claim 61 further wherein establishing the filtered wireless zone comprises scanning signaling channels serving a geographic vicinity;

recording channel identity and system identity of each signaling channel;

commanding a transmitter-receiver to such channel, causing the transmitter-receiver to radiate a signaling channel marker; and

transmitting a new signaling channel assignment message, sending handsets to a new capture channel.

66. The method of creating a virtual phone booth of claim 61 further wherein the step of causing the system control to radiate a signaling channel marker comprises including in that the identity of the ordinary system it is supplanting.

67. The method of creating a virtual phone booth of claim 61 further including ensuring the strength of signals are higher than signal strengths normally serving the filtered wireless zone.
